Philosophical Letters : OR , MODEST REFLECTIONS Upon some Opinions in NATVRAL PHILOSOPHY , MAINTAINED By several Famous and Learned Authors of this Age , Expressed by way of LETTERS : By the Thrice Noble , Illustrious , and Excellent Princess , The Lady MARCHIONESS of NEWCASTLE .

LONDON , Printed in the Year , 1664.

TO HER EXCELLENCY The Lady MARCHIONESS OF NEW CASTLE , On her Book of Philosophical Letters . T Is Supernatural , nay 't is Divine , To write whole Volumes ere I can a line . I'mplor'd the Lady Muses , those fine things , But they have broken all their Fidle-strings And cannot help me ; Nay , then I did try Their Helicon , but that is grown all dry : Then on Parnassus I did make a sallie , But that 's laid level , like a Bowling-alley ; Invok'd my Muse , found it a Pond , a Dream , To your eternal Spring , and running Stream ; So clear and fresh , with Wit and Phansie store , As then despair did bid me write no more . W. Newcastle .
TO HIS EXCELLENCY The LORD MARQUIS of NEW CASTLE . My Noble Lord ,

ALthough you have always encouraged me in my harmless pastime of Writing , yet was I afraid that your Lordship would be angry with me for Writing and Publishing this Book , by reason it is a Book of Controversies , of which I have heard your Lordship say , That Controversies and Disputations make Enemies of Friends , and that such Disputations and Controversies as these , are a pedantical kind of quarrelling , not becoming Noble Persons . But your Lordship will be pleased to consider in my behalf , that it is impossible for one Person to be of every one's Opinion , if their opinions be different , and that my Opinions in Philosophy , being new , and never thought of , at least not divulged by any , but my self , are quite different from others : For the Ground of my Opinions is , that there is not onely a Sensitive , but also a Rational Life and Knowledge , and so a double Perception in all Creatures : And thus my opinions being new , are not so easily understood as those , that take vp several pieces of old opinions , of which they patch up a new Philosophy , ( if new may be made of old things , ) like a Suit made up of old Stuff bought at the Brokers : Wherefore to find out a Truth , at least a Probability in Natural Philosophy by a new and different way from other Writers , and to make this way more known , easie and intelligible , I was in a manner forced to write this Book ; for I have not contradicted those Authors in any thing , but what concerns and is opposite to my opinions ; neither do I any thing , but what they have done themselves , as being common amongst them to contradict each other : which may as well be allowable , as for Lawyers to plead at the Barr in opposite Causes . For as Lawyers are not Enemies to each other , but great Friends , all agreeing from the Barr , although not at the Barr : so it is with Philosophers , who make their Opinions as their Clients , not for Wealth , but for Fame , and therefore have no reason to become Enemies to each other , by being Industrious in their Profession . All which considered , was the cause of Publishing this Book ; wherein although I dissent from their opinions , yet doth not this take off the least of the respect and esteem I have of their Merits and Works . But if your Lordship do but pardon me , I care not if I be condemned by others ; for your Favour is more then the World to me , for which all the actions of my Life shall be devoted and ready to serve you , as becomes ,

My LORD , Your Lordships honest Wife , and humble Servant , M. N.
TO THE MOST FAMOUS UNIVERSITY OF CAMBRIDGE . Most Noble , Ingenious , Learned , and Industrious Students .

BE not offended , that I dedicate to you this weak and infirm work of mine ; for though it be not an offering worthy your acceptance , yet it is as much as I can present for this time ; and I wish from my Soul , I might be so happy as to have some means or ways to express my Gratitude for your Magnificent favours to me , having done me more honour then ever I could expect , or give sufficient thanks for : But your Generosity is above all Gratitude , and your Favours above all Merit , like as your Learning is above Contradiction : And I pray God your University may flourish to the end of the World , for the Service of the Church , the Truth of Religion , the Salvation of Souls , the Instruction of Youth , the preservation of Health , and prolonging of Life , and for the increase of profitable Arts and Sciences : so as your several studies may be , like several Magistrates , united for the good and benefit of the whole Common-wealth , nay , the whole World . May Heaven prosper you , the World magnifie you , and Eternity record your fame ; Which are the hearty wishes and prayers of ,

Your most obliged Servant M. NEWCASTLE .
A PREFACE TO THE READER . Worthy Readers ,

I Did not write this Book out of delight , love or humour to contradiction ; for I would rather praise , then contradict any Person or Persons that are ingenious ; but by reason Opinion is free , and may pass without a pass-port , I took the liberty to declare my own opinions as other Philosophers do , and to that purpose I have here set down several famous and learned Authors opinions , and my answers to them in the form of Letters , which was the easiest way for me to write ; and by so doing , I have done that , which I would have bone unto me ; for I am as willing to have my opinions contradicted , as I do contradict others : for I love Reason so well , that whosoever can bring most rational and probable arguments , shall have my vote , although against my own opinion . But you may say , If contradictions were frequent , there would be no agreement amongst Mankind . I answer ; It is very true : Wherefore Contradictions are better in general Books , then in particular Families , and in Schools better then in Publick States , and better in Philosophy then in Divinity . All which considered , I shun , as much as I can , not to discourse or write of either Church or State . But I desire so much favour , or rather Justice of you , Worthy Readers , as not to interpret my objections or answers any other ways then against several opinions in Philosophy ; for I am confident there is not any body , that doth esteem , respect and honour learned and ingenious Persons more then I do : Wherefore judg me neither to be of a contradicting humor , nor of a vain-glorious mind for dissenting from other mens opinions , but rather that it is done out of love to Truth , and to make my own opinions the more intelligible , which cannot better be done then by arguing and comparing other mens opinions with them . The Authors whose opinions I mention , I have read , as I found them printed , in my native Language , except Des Cartes , who being in Latine , I had some few places translated to me out of his works ; and I must confess , that since I have read the works of these learned men , I understand the names and terms of Art a little better then I did before ; but it is not so much as to make me a Scholar , nor yet so little , but that , had I read more before I did begin to write my other Book called Philosophical Opinions , they would have been more intelligible ; for my error was , I began to write so early , that I had not liv'd so long as to be able to read many Authors ; I cannot say , I divulged my opinions as soon as I had conceiv'd them , but yet I divulged them too soon to have them artificial and methodical , But since what is past , cannot be recalled , I must desire you to excuse those faults , which were committed for want of experience and learning . As for School-learning , had I applied my self to it , yet I am confident I should never have arrived to any ; for I am so uncapable of Learning , that I could never attain to the knowledge of any other Language but my native , especially by the Rules of Art : wherefore I do not repent that I spent not my time in Learning , for I consider , it is better to write wittily then learnedly ; nevertheless , I love and esteem Learning , although I am not capable of it . But you may say , I have expressed neither Wit nor Learning in my Writings : Truly , if not , I am the more sorry for it ; but self-conceit , which is natural to mankind , especially to our Sex , did flatter and secretly perswade me that my Writings had Sense and Reason , Wit and Variety ; but Judgment being not called to Counsel , I yielded to Self-conceits flattery , and so put out my Writings to be Printed as fast as I could , without being reviewed or corrected : Neither did I fear any censure , for Self-conceit had perswaded me , I should be highly applauded ; wherefore I made such haste , that I had three or four Books printed presently after each other .

But to return to this present Work , I must desire you , worthy Readers , to read first my Book called Philosophical and Physical Opinions , before you censure this , for this Book is but an explanation of the former , wherein is contained the Ground of my Opinions , and those that will judge well of a Building , must first consider the Foundation ; to which purpose I will repeat some few Heads and Principles of my Opinions , which are these following : First , That Nature is Infinite , and the Eternal Servant of God : Next , That she is Corporeal , and partly self-moving , dividable and composable ; that all and every particular Creature , as also all perception and variety in Nature , is made by corporeal self-motion , which I name sensitive and rational matter , which is life and knowledg , sense and reason . Again , That these sensitive and rational parts of matter are the purest and subtilest parts of Nature , as the active parts , the knowing , understanding and prudent parts , the designing , architectonical and working parts , nay , the Life and Soul of Nature , and that there is not any Creature or part of nature without this Life and Soul ; and that not onely Animals , but also Vegetables , Minerals and Elements , and what more is in Nature , are endued with this Life and Soul , Sense and Reason : and because this Life and Soul is a corporeal Substance , it is both dividable and composable ; for it divides and removes parts from parts , as also composes and joyns parts to parts , and works in a perpetual motion without rest ; by which actions not any Creature can challenge a particular Life and Soul to it self , but every Creature may have by the dividing and composing nature of this self-moving matter more or fewer natural souls and lives .

These and the like actions of corporeal Nature or natural Matter you may find more at large described in my afore-mentioned Book of Philosophical Opinions , and more clearly repeated and explained in this present . T is true , the way of arguing I use , is common , but the Principles , Heads and Grounds of my Opinions are my own , not borrowed or stolen in the least from any ; and the first time I divulged them , was in the year 1653. since which time I have reviewed , reformed and reprinted them twice ; for at first , as my Conceptions were new and my own , so my Judgment was young , and my Experience little , so that I had not so much knowledge as to declare them artificially and methodically ; for as I mentioned before , I was always unapt to learn by the Rules of Art . But although they may be defective for want of Terms of Art , and artificial expressions , yet I am sure they are not defective for want of Sense and Reason : And if any one can bring more Sense and Reason to disprove these my opinions , I shall not repine or grieve , but either acknowledge my errour , if I find my self in any , or defend them as rationally as I can , if it be but done justly and honestly , without deceit , spight , or malice ; for I connot chuse but acquaint you , Noble Readers , I have been informed , that if I should be answered in my Writings , it would be done rather under the name and cover of a Woman , then of a Man , the reason is , because no man dare or will set his name to the contradiction of a Lady ; and to confirm you the better herein , there has one Chapter of my Book called The Worlds Olio , treating of a Monastical Life , been answer'd already in a little Pamphlet , under the name of a woman , although she did little towards it ; wherefore it being a Hermaphroditical Book , I judged it not worthy taking notice of . The like shall I do to any other that will answer this present work of mine , or contradict my opinions indirectly with fraud and deceit . But I cannot conceive why it should be a disgrace to any man to maintain his own or others opinions against a woman , so it be done with respect and civility ; but to become a cheat by dissembling , and quit the Breeches for a Petticoat , meerly out of spight and malice , is base , and not fit for the honour of a man , or the masculine sex . Besides , it will easily be known ; for a Philosopher or Philosopheress is not produced on a sudden . Wherefore , although I do not care , nor fear contradiction , yet I desire it may be done without fraud or deceit , spight and malice ; and then I shall be ready to defend my opinions the best I can , whilest I live , and after I am dead , I hope those that are just and honorable will also defend me from all sophistry , malice , spight and envy , for which Heaven will bless them . In the mean time , Worthy Readers , I should rejoyce to see that my Works are acceptable to you , for if you be not partial , you will easily pardon those faults you find , when you do consider both my sex and breeding ; for which favour and justice , I shall always remain ,

SECT. 1.
1. MADAM ,

YOu have been pleased to send me the Works of four Famous and Learned Authors , to wit , of two most Famous Philosophers of our Age , Des Gartes , and Hobbs , and of that Learned Philosopher and Divine Dr. More , as also of that Famous Physician and Chymist Van Helmont . Which Works you have sent me not onely to peruse , but also to give my judgment of them , and to send you word by the usual way of our Correspondence , which is by Letters , how far , and wherein I do dissent from these Famous Authors , their Opinions in Natural Philosophy . To tell you truly , Madam , your Commands did at first much affright me , for it did appear , as if you had commanded me to get upon a high Rock , and fling my self into the Sea , where neither a Ship , nor a Plank , nor any kind of help was near to rescue me , and save my life ; but that I was forced to sink , by reason I cannot swim : So I having no Learning nor Art to assist me in this dangerous undertaking , thought , I must of necessity perish under the rough censures of my Readers , and be not onely accounted a fool for my labour , but a vain and presumptuous person , to undertake things surpassing the ability of my performance ; but on the other side I considered first , that those Worthy Authors , were they my censurers , would not deny me the same liberty they take themselves ; which is , that I may dissent from their Opinions , as well as they dissent from others , and from amongst themselves : And if I should express more Vanity then Wit , more Ignorance then Knowledg , more Folly then Discretion , it being according to the Nature of our Sex , I hoped that my Masculine Readers would civilly excuse me , and my Female Readers could not justly condemn me . Next I considered with my self , that it would be a great advantage for my Book called Philosophical Opinions , as to make it more perspicuous and intelligible by the opposition of other Opinions , since two opposite things placed near each other , are the better discerned ; for I must confess , that when I did put forth my Philosophical Work at first , I was not so well skilled in the Terms or Expressions usual in Natural Philosophy ; and therefore for want of their knowledg , I could not declare my meaning so plainly and clearly as I ought to have done , which may be a sufficient argument to my Readers , that I have not read heretofore any Natural Philosophers , and taken some Light from them ; but that my Opinions did meerly issue from the Fountain of my own Brain , without any other help or assistance . Wherefore since for want of proper Expressions , my named Book of Philosophy was accused of obscurity and intricacy , I thought your Commands would be a means to explain and clear it the better , although not by an Artificial way , as by Logical Arguments or Mathematical Demonstrations , yet by expressing my Sense and Meaning more properly and clearly then I have done heretofore : But the chief reason of all was , the Authority of your Command , which did work so powerfully with me , that I could not resist , although it were to the disgrace of my own judgment and wit ; and therefore I am fully resoved now to go on as far , and as well as the Natural strength of my Reason will reach : but since neither the strength of my Body , nor of my understanding , or wit , is able to mark every line , or every word of their works , and to argue upon them , I shall onely pick out the ground Opinions of the aforementioned Authors , and those which do directly dissent from mine , upon which I intend to make some few Reflections , according to the ability of my Reason ; and I shall meerly go upon the bare Ground of Natural Philosophy , and not mix Divinity with it , as many Philosophers use to do , except it be in those places , where I am forced by the Authors Arguments to reflect upon it , which yet shall be rather with an expression of my ignorance , then a positive declaration of my opinion or judgment thereof ; for I think it not onely an absurdity , but an injury to the holy Profession of Divinity to draw her to the Proofs in Natural Philosophy ; wherefore I shall strictly follow the Guidance of Natural Reason , and keep to my own ground and Principles as much as I can ; which that I may perform the better , I humbly desire the help and assistance of your Favour , that according to that real and intire Affection you bear to me , you would be pleased to tell me unfeignedly , if I should chance to err or contradict but the least probability of truth in any thing ; for I honor Truth so much , as I bow down to its shadow with the greatest respect and reverence ; and I esteem those persons most , that love and honor Truth with the same zeal and fervor , whether they be Ancient or Modern Writers .

Thus , Madam , although I am destitute of the help of Arts , yet being supported by your Favour and wise Directions , I shall not fear any smiles of scorn , or words of reproach ; for I am confident you will defend me against all the mischievous and poisonous Teeth of malitious detractors . I shall besides , implore the assistance of the Sacred Church , and the Learned Schools , to take me into their Protection , and shelter my weak endeavours : For though I am but an ignorant and simple Woman , yet I am their devoted and honest Servant , who shall never quit the respect and honor due to them , but live and die theirs , as also ,

MADAM , Your Ladiships humble and faithful Servant .
II. MADAM ,

BEfore I begin my Reflections upon the Opinions of those Authors you sent me , I will answer first your Objection concerning the Ground of my Philosophy , which is Infinite Matter : For you were pleased to mention , That you could not well apprehend , how it was possible , that many Infinites could be contained in one Infinite , since one Infinite takes up all Place Imaginary , leaving no room for any other ; Also , if one Infinite should be contained in an other Infinite , that which contains , must of necessity be bigger then that which is contained , whereby the Nater of Infinite would be lost ; as having no bigger nor less , but being of an Infinite quantity .

First of all , Madam , there is no such thing as All in Infinite , nor any such thing as All the Place , for Infinite is not circumscribed nor limited : Next , as for that one Infinite cannot be in an other Infinite , I answer , as well as one Finite can be in another Finite ; for one Creature is not onely composed of Parts , but one Part lies within another , and one Figure within another , and one Motion within another . As for example , Animal Kind , have they not Internal and External Parts , and so Internal and External Motions ? And are not Animals , Vegetables and Minerals inclosed in the Elements ? But as for Infinites , you must know , Madam , that there are several kindes of Infinites . For there is first Infinite in quantity or bulk , that is such a big and great Corporeal substance , which exceeds all bounds and limits of measure , and may be called Infinite in Magnitude . Next there is Infinite in Number , which exceeds all numeration and account , and may be termed Infinite in Multitude ; Again there is Infinite in Quality ; as for example , Infinite degrees of softness , hardness , thickness , thinness , heat and cold , &c. also Infinite degrees of Motion , and so Infinite Creations , Infinite Compositions , Dissolutions , Contractions , Dilations , Digestions , Expulsions ; also Infinite degrees of Strength , Knowledg , Power , &c. Besides there is Infinite in Time , which is properly named Eternal . Now , when I say , that there is but one Infinite , and that Infinite is the Onely Matter , I mean infinite in bulk and quantity . And this Onely matter , because it is Infinite in bulk , must of necessity be divisible into infinite Parts , that is , infinite in number , not in bulk or quantity ; for though Infinite Parts in number make up one infinite in quantity , yet they considered in themselves , cannot be said Infinite , because every Part is of a certain limited and circumscribed Figure , Quantity and Proportion , whereas Infinite hath no limits nor bounds : besides it is against the nature of a single Part to be Infinite , or else there would be no difference between the Part and the whole , the nature of a Part requiring that it must be less then its whole , but all what is less hath a determined quantity , and so becomes finite . Therefore it is no absurdity to say , that an Infinite may have both Finite and Infinite Parts , Finite in Quantity , Infinite in Number . But those that say , if there were an Infinite Body , that each of its Parts must of necessity be Infinite too , are much mistaken ; for it is a contradiction in the same Terms to say One Infinite Part , for the very Name of a Part includes a Finiteness , but take all parts of an Infinite Body together , then you may rightly say they are infinite . Nay Reason will inform you plainly , for example : Imagine an Infinite number of grains of Corn in one heap , surely if the number of Grains be Infinite , you must grant of necessity the bulk or body , which contains this infinite number of grains , to be Infinite too ; to wit , Infinite in quantity , and yet you will find each Grain in it self to be Finite . But you will say , an Infinite Body cannot have parts , for if it be Infinite , it must be Infinite in Quantity , and therefore of one bulk , and one continued quantity , but Infinite parts in number make a discrete quantity . I answer it is all one ; for a Body of a continued quantity may be divided and severed into fo many Parts either actually , or mentally in our Conceptions or thoughts ; besides nature is one continued Body , for there is no such Vacuum in Nature , as if her Parts did hang together like a linked Chain ; nor can any of her Parts subsist single and by it self , but all the Parts of Infinite Nature , although they are in one continued Piece , yet are they several and discerned from each other by their several Figures . And by this , I hope , you will understand my meaning , when I say , that several Infinites may be included or comprehended in one Infinite ; for by the one Infinite , I understand Infinite in Quantity , which includes Infinite in Number , that is Infinite Parts ; then Infinite in Quality , as Infinite degrees of Rarity , Density , Swiftness , Slowness , Hardness , Softness , &c. Infinite degrees of Motions , Infinite Creations , Dissolutions , Contractions , Dilations , Alterations , &c. Infinite degres of Wisdom , Strength , Power , &c. and lastly Infinite in Time or Duration , which is Eternity , for Infinite and Eternal are inseparable ; All which Infinites are contained in the Onely Matter as many Letters are contained in one Word , many Words in one Line , many Lines in one Book . But you will say perhaps , if I attribute an Infinite Wisdom , Strength , Power , Knowledge , &c. to Nature ; then Nature is in all coequal with God , for God has the same Attributes : I answer , Not at all ; for I desire you to understand me rightly , when I speak of Infinite Nature , and when I speak of the Infinite Deity , sor there is great difference between them , for it is one thing a Deitical or Divine Infinite , and another a Natural Infinite ; You know , that God is a Spirit , and not a bodily substance , again that Nature is a Body , and not a Spirit , and therefore none of these Infinites can obstruct or hinder each other , as being different in their kinds , for a Spirit being no Body , requires no place , Place being an attribute which onely belongs to a Body , and therefore when I call Nature Infinite , I mean an Infinite extension of Body , containing an Infinite number of Parts ; but what doth an Infinite extension of Body hinder the Infiniteness of God , as an Immaterial Spiritual being ? Next , when I do attribute an Infinite Power , Wisdom , Knowledge , &c. to Nature , I do not understand a Divine , but a Natural Infinite Wisdom and Power , that is , such as properly belongs to Nature , and not a supernatural , as is in god ; For Nature having Infinite parts of Infinite degrees , must also have an Infinite natural wisdom to order her natural Infinite parts and actions , and consequently an Infinite natural power to put her wisdom into act ; and so of the rest of her attributes , which are all natural : But Gods Attributes being supernatural , transcend much these natural infinite attributes ; for God , being the God of Nature , has not onely Natures Infinite Wisdom and Power , but besides , a Supernatural and Incomprehensible Infinite Wisdom and Power ; which in no wayes do hinder each other , but may very well subsist together . Neither doth Gods Infinite Justice and his Infinite Mercy hinder each other ; for Gods Attributes , though they be all several Infinites , yet they make but one Infinite .

But you will say , If Nature's Wisdom and Power extends no further then to natural things , it is not Infinite , but limited and restrained . I answer , That doth not take away the Infiniteness of Nature ; for there may be several kinds of Infinites , as I related before , and one may be as perfect an Infinite as the other in its kind . For example : Suppose a Line to be extended infinitely in length , you will call this Line Infinite , although it have not an Infinite breadth : Also , if an infinite length and breadth joyn together , you will call it , an Infinite Superficies , although it wants an infinite depth ; and yet every Infinite , in its kinde , is a Perfect Infinite , if I may call it so : Why then shall not Nature also be said to have an Infinite Natural Wisdom and Power , although she has not a Divine Wisdom and Power ? Can we say , Man hath not a free Will , because he hath not an absolute free Will , as God hath ? Wherefore , a Natural Infinite , and the Infinite God , may well stand together , without any opposition or hinderance , or without any detracting or derogating from the Omnipotency and Glory of God ; for God remains still the God of Nature , and is an Infinite Immaterial Purity , when as Nature is an Infinite Corporeal Substance ; and Immaterial and Material cannot obstruct each other . And though an Infinite Corporeal cannot make an Infinite Immaterial , yet an Infinite Immaterial can make an Infinite Corporeal , by reason there is as much difference in the Power as in the Purity : And the disparity between the Natural and Divine Infinite is such , as they cannot joyn , mix , and work together , unless you do believe that Divine Actions can have allay .

But you may say , Purity belongs onely to natural things , and none but natural bodies can be said purified , but God exceeds all Purity . 'T is true : But if there were infinite degrees of Purity in Matter , Matter might at last become Immaterial , and so from an Infinite Material turn to an Infinite Immaterial , and from Natrue to be God : A great , but an impossible Change . For I do verily believe , that there can be but one Omnipotent God , and he cannot admit of addition , or diminution ; and that which is Material cannot be Immaterial , and what is Immaterial cannot become Material , I mean , so , as to change their natures ; for Nature is what God was pleased she should be ; and will be what she was , until God be pleased to make her otherwise . Wherefore there can be no new Creation of matter , motion , or figure ; nor any annihilation of any matter , motion , or figure in Nature , unless God do create a new Nature : For the changing of Matter into several particular Figures , doth not prove an annihilation of particular Figures ; nor the cessation of particular Motions an annihilation of them : Neither doth the variation of the Onely Matter produce an annihilation of any part of Matter , nor the variation of figures and motions of Matter cause an alteration in the nature of Onely Matter : Wherefore there cannot be new Lives , Souls or Bodies in Nature ; for , could there be any thing new in Nature , or any thing annihilated , there would not be any stability in Nature , as a continuance of every kind and sort of Creatures , but there would be a confusion between the new and old matter , motions , and figures , as between old and new Nature ; In truth , it would be like new Wine in old Vessels , by which all would break into disorder . Neither can supernatural and natural effects be mixt together , no more then material and immaterial things or beings : Therefore it is probable , God has ordained Nature to work in herself by his Leave , Will , and Free Gift . But there have been , and are still strange and erroneous Opinions , and great differences amongst Natural Philosophers , concerning the Principles of Natural things ; some will have them Atoms , others will have the first Principles to be Salt , Sulphur and Mercury ; some will have them to be the four Elements , as Fire , Air , Water , and Earth ; and others will have but one of these Elements ; also some will have Gas and Blas , Ferments , Idea's , and the like ; but what they believe to be Principles and Causes of natural things , are onely Effects ; for in all Probability it appears to humane sense and reason , that the cause of every particular material Creature is the onely and Infinite Matter , which has Motions and Figures inseparably united ; for Matter , Motion and Figure , are but one thing , individable in its Nature . And as for Immaterial Spirits , there is surely no such thing in Infinite Nature , to wit , so as to be Parts of Nature ; for Nature is altogether Material , but this opinion proceeds from the separation or abstraction of Motion form Matter , viz. that man thinks matter and motion to be dividable from each other , and believes motion to be a thing by its self , naming it an Imaterial thing , which has a being , but not a bodily substance : But various and different effects do not prove a different Matter or Cause , neither do they prove an unsetled Cause , onely the variety of Effects hath obscured the Cause from the several parts , which makes Particular Creatures partly Ignorant , and partly knowing . But in my opinion , Nature is material , and not any thing in Nature , what belongs to her , is immaterial ; but whatsoever is Immaterial , is Supernatural , Therefore Motions , Forms , Thoughts , Ideas , Conceptions , Sympathies , Antipathies , Accidents , Qualities , as also Natural Life , and Soul , are all Material : And as for Colours , Sents , Light , Sound , Heat , Cold , and the like , those that believe them not to be substances or material things , surely their brain or heart ( take what place you will for the forming of Conceptions ) moves very Irregularly , and they might as well say , Our sensitive Organs are not material ; for what Objects soever , that are subject to our senses , cannot in sense be denied to be Corporeal , when as those things that are not subject to our senses , can be conceived in reason to be Immaterial ? But some Philosophers striving to express their wit , obstruct reason ; and drawing Divinity to prove Sense and Reason , weaken Faith so , as their mixed Divine Philosophy becomes meer Poetical Fictions , and Romancical expressions , making material Bodies immaterial Spirits , and immaterial Spirits material Bodies ; and some have conceived some things neither to be Material nor Immaterial , but between both . Truly , Madam , I wish their Wits had been less , and their Judgments more , as not to jumble Natural and Supernatural things together , but to distinguish either clearly , for such Mixtures are neither Natural nor Divine ; But as I said , the Confufion comes from their too nice abstractions , and from the separation of Figure and Motion from Matter , as not conceiving them individable ; but if God , and his servant Nature were as Intricate and Confuse in their Works , as Men in their Understandings and Words , the Universe and Production of all Creatures would soon be without Order and Government , so as there would be a horrid and Eternal War both in Heaven , and in the World , and so pittying their troubled Brains , and wishing them the Light of Reason , that they may clearly perceive the Truth , I rest

IT seems you are offended at my Opinion , that Nature is Eternal without beginning , which , you say , is to make her God , or at least coeqnal with God ; But , if you apprehend my meaning rightly , you will say , I do not : For first , God is an Immaterial and Spiritual Infinite Being , which Propriety God cannot give away to any Creature , nor make another God in Essence like to him , for Gods Attributes are not communicable to any Creature ; Yet this doth not hinder , that God should not make Infinite and Eternal Matter , for that is as easie to him , as to make a Finite Creature , Infinite Matter being quite of another Nature then God is , to wit , Corporeal , when God is Incorporeal , the difference whereof I have declared in my former Letter . But as for Nature , that it cannot be Eternal without beginning , because God is the Creator and Cause of it , and that the Creator must be before the Creature , as the Cause before the Effect , so , that it is impossible for Nature to be without a beginning ; if you will speak naturally , as human reason guides you , and bring an Argument concluding from the Priority of the Cause before the Effect , give me leave to tell you , that God is not tied to Natural Rules , but that he can do beyond our Understanding , and therefore he is neither bound up to time , as to be before , for if we will do this , we must not allow , that the Eternal Son of God is Coeternal with the Father , because nature requires a Father to exist before the Son , but in God is no time , but all Eternity ; and if you allow , that God hath made some Creatures , as Supernatural Spirits , to live Eternally , why should he not as well have made a Creature from all Eternity ? for Gods making is not our making , he needs no Priority of Time . But you may say , the Comparison of the Eternal Generation of the Son of God is Mystical and Divine , and not to be applied to natural things : I answer , The action by which God created the World or made Nature , was it natural of supernatural ? surely you will say it was a Supernatural and God-like action , why then will you apply Natural Rules to a God-like and Supernatural Action ? for what Man knows , how and when God created Nature ? You will say , the Scripture doth teach us that , for it is not Six thousand years , when God created this World . I answer , the holy Scripture informs us onely of the Creation of this Visible World , but not of Nature and natural Matter ; for I firmly believe according to the Word of God , that this World has been Created , as is described by Moses , but what is that to natural Matter ? There may have been worlds before , as many are of the opinion that there have been men before Adam , and many amongst Divines do believe , that after the destruction of this World God will Create a new World again , as a new Heaven , and a new Earth ; and if this be probable , or at least may be believed without any prejudice to the holy Scripture , why may it not be probably believed that there have been other worlds before this visible World ? for nothing is impossible with God ; and all this doth derogate nothing from the Honour and Glory of God , but rather increases his Divine Power . But as for the Creation of this present World , it is related , that there was first a rude and indigested Heap , or Chaos , without form , void and dark ; and God said , Let it be light ; Let there be a Firmament in the midst of the Waters , and let the Waters under the Heaven be gathered together , and let the dry Land appear ; Let the Earth bring forth Grass , the Herb yielding seed , and the Fruit-tree yielding Fruit after its own kind ; and let there be Lights in the Firmament , the one to rule the Day , and the other the Night ; and let the Waters bring forth abundantly the moving Creature that hath life ; and let the Earth bring forth living Creatures after its kinde ; and at last God said , Let us make Man , and all what was made , God saw it was good . Thus all was made by Gods Command , and who executed his Command but the Material servant of God , Nature ? which ordered her self-moving matter into such several Figures as God commanded , and God approved of them . And thus , Madam , I verily believe the Creation of the World , and that God is the Sole and omnipotent Creator of Heaven and Earth , and of all Creatures therein ; nay , although I believe Nature to have been from Eternity , yet I believe also that God is the God and Author of Nature , and has made Nature and natural Matter in a way and manner proper to his Omnipotency and Incomprehensible by us : I will pass by natural Arguments and Proofs , as not belonging to such an Omnipotent Action ; as for example , how the nature of relative terms requires , that they must both exist at one point of Time , viz. a Master and his Servant , and a King and his Subjects ; for one bearing relation to the other , can in no ways be considered as different from one another in formiliness or laterness of Time ; but as I said , these being meerly natural things , I will nor cannot apply them to Supernatural and Divine Actions ; But if you ask me , how it is possible that Nature , the Effect and Creature of God , can be Eternal without beginning ? I will desire you to answer me first , how a Creature can be Eternal without end , as , for example , Supernatural Spirits are , and then I will answer you , how a Creature can be Eternal without beginning ; For Eternity consists herein , that it has neither beginning nor end ; and if it be easie for God to make a Being without end , it is not difficult for Him to make a Being without beginning . One thing more I will add , which is , That if Nature has not been made by God from all Eternity , then the Title of God , as being a Creator , which is a Title and action , upon which our Faith is grounded , ( for it is the first Article in our Creed ) has been accessory to God , as I said , not full Six thousand years ago ; but there is not anything accessory to God , he being the Perfection himself . But , Madam , all what I speak , is under the liberty of Natural Philosophy , and by the Light of Reason onely , not of Revelation ; and my Reason being not infallible , I will not declare my Opinions for an infallible Truth : Neither do I think , that they are offensive either to Church or State , for I submit to the Laws of One , and believe the Doctrine of the Other , so much , that if it were for the advantage of either , I should be willing to sacrifice my Life , especially for the Church ; yea , had I millions of Lives , and every Life was either to suffer torment or to live in ease , I would prefer torment for the benefit of the Church ; and therefore , if I knew that my Opinions should give any offence to the Church , I should be ready every minute to alter them : And as much as I am bound in all duty to the obedience of the Church , as much am I particularly bound to your Ladiship , for your entire love and sincere affection towards me , for which I shall live and die ,

I Have chosen , in the first place , the Work of that famous Philosopher Hobbs , called Leviathan , wherein I find he sayes , * * Part. 1. ch. 1. That the cause of sense or sensitive perception is the external body or Object , which presses the Organ proper to each Sense . To which I answer , according to the ground of my own Philosophical Opinions , That all things , and therefore outward objects as well as sensitive organs , have both Sense and Reason , yet neither the objects nor the organs are the cause of them ; for Perception is but the effect of the Sensitive and rational Motions , and not the Motions of the Perception ; neither doth the pressure of parts upon parts make Perception ; for although Matter by the power of self-motion is as much composeable as divideable , and parts do joyn to parts , yet that doth not make perception ; nay , the several parts , betwixt which the Perception is made , may be at such a distance , as not capable to press : As for example , Two men may see or hear each other at a distance , and yet there may be other bodies between them , that do not move to those perceptions , so that no pressure can be made , for all pressures are by some constraint and force ; wherefore , according to my Opinion , the Sensitive and Rational free Motions , do pattern out each others object , as Figure and Voice in each others Eye and Ear ; for Life and Knowledge , which I name Rational and Sensitive Matter , are in every Creature , and in all parts of every Creature , and make all perceptions in Nature , because they are the self-moving parts of Nature , and according as those Corporeal , Rational , and Sensitive Motions move , such or such perceptions are made : But these self-moving parts being of different degrees ( for the Rational matter is purer then the Sensitive ) it causes a double perception in all Creatures , whereof one is made by the Rational corporeal motions , and the other by the Sensitive ; and though both perceptions are in all the body , and in every part of the body of a Creature , yet the sensitive corporeal motions having their proper organs , as Work-houses , in which they work some sorts of perceptions , those perceptions are most commonly made in those organs , and are double again ; for the sensitive motions work either on the inside or on the outside of those organs , on the inside in Dreams , on the out-side awake ; and although both the Rational and the Sensitive matter are inseparably joyned and mixed together , yet do they not always work together , for oftentimes the Rational works without any sensitive paterns , and the sensitive again without any rational paterns . But mistake me not , Madam , for I do not absolutely confine the sensitive perception to the Organs , nor the rational to the Brain , but as they are both in the whole body , so they may work in the whole body according to their own motions . Neither do I say , that there is no other perception in the Eye but sight , in the Ear but hearing , and so forth , but the sensitive organs have other perceptions besides these ; and if the sensitive and rational motions be irregular in those parts , between which the perception is made , as for example , in the two fore-mentioned men , that see and hear each other , then they both neither see nor hear each other perfectly ; and if one's motions be perfect , but the other 's irregular and erroneous , then one sees and hears better then the other ; or if the Sensitive and Rational motions move more regularly and make perfecter paterns in the Eye then in the Ear , then they see better then they hear ; and if more regularly and perfectly in the Ear then in the Eye , they hear better then they see : And so it may be said of each man singly , for one man may see the other better and more perfectly , then the other may see him ; and this man may hear the other better and more perfectly , then the other may hear him ; whereas , if perception were made by pressure , there would not be any such mistakes ; besides the hard pressure of objects , in my opinion , would rather annoy and obscure , then inform . But as soon as the object is removed , the Perception of it , made by the sensitive motions in the Organs , ceaseth , by reason the sensitive Motions cease from paterning , but yet the Rational Motions do not always cease so suddenly , because the sensitive corporeal Motions work with the Inanimate Matter , and therefore cannot retain particular figures long , whereas the Rational Matter doth onely move in its own substance and parts of matter , and upon none other , as my Book of Philosophical Opinions will inform you better . And thus Perception , in my opinion , is not made by Pressure , nor by Species , nor by matter going either from the Organ to the Object , or from the Object into the Organ . By this it is also manifest , that Understanding comes not from Exterior Objects , or from the Exterior sensitive Organs ; for as Exterior Objects do not make Perception , so they do neither make Understanding , but it is the rational matter that doth it , for Understanding may be without exterior objects and sensitive organs ; And this in short is the opinion of

V. MADAM ,

YOur Authours opinion is , * * Leviathan , Part. 1. c. 2. that when a thing lies still , unless somewhat else stir it , it will lie still for ever ; but when a thing is in motion , it will eternally be in motion , unless somewhat else stay it ; the reason is , saith he , because nothing can change it self ; To tell you truly , Madam , I am not of his opinion , for if Matter moveth it self , as certainly it doth , then the least part of Matter , were it so small as to seem Individable , will move it self ; T is true , it could not desist from motion , as being its nature to move , and no thing can change its Nature ; for God himself , who hath more power then self-moving Matter , cannot change himself from being God ; but that Motion should proceed from another exterior Body , joyning with , or touching that body which it moves , is in my opinion not probable ; for though Nature is all Corporeal , and her actions are Corporeal Motions , yet that doth not prove , that the Motion of particular Creatures or Parts is caused by the joining , touching or pressing of parts upon parts ; for it is not the several parts that make motion , but motion makes them ; and yet Motion is not the cause of Matter , but Matter is the cause of Motion , for Matter might subsist without Motion , but not Motion without Matter , onely there could be no perception without Motion , nor no Variety , if Matter were not self-moving ; but Matter , if it were all Inanimate and void of Motion , would lie as a dull , dead and senseless heap ; But that all Motion comes by joining or pressing of other parts , I deny , for if sensitive and rational perceptions , which are sensitive and rational motions , in the body , and in the mind , were made by the pressure of outward objects , pressing the sensitive organs , and so the brain or interior parts of the Body , they would cause such dents and holes therein , as to make them sore and patched in a short time ; Besides , what was represented in this manner , would always remain , or at least not so soon be dissolved , and then those pressures would make a strange and horrid confusion of Figures , for not any figure would be distinct ; Wherefore my opinion is , that the sensitive and rational Matter doth make or pattern out the figures of several Objects , and doth dissolve them in a moment of time ; as for example , when the eye seeth the object first of a Man , then of a Horse , then of another Creature , the sensitive motions in the eye move first into the figure of the Man , then straight into the figure of the Horse , so that the Mans figure is dissolved and altered into the figure of the Horse , and so forth ; but if the eye sees many figures at once , then so many several figures are made by the sensitive Corporeal Motions , and as many by the Rational Motions , which are Sight and Memory , at once : But in sleep both the sensitive and rational Motions make the figures without patterns , that is , exterior objects , which is the cause that they are often erroneous , whereas , if it were the former Impression of the Objects , there could not possibly be imperfect Dreams or Remembrances , for fading of Figures requires as much motion , as impression , and impression and fading are very different and opposite motions ; nay , if Perception was made by Impression , there could not possibly be a fading or decay of the figures printed either in the Mind or Body , whereas yet , as there is alteration of Motions in self-moving Matter , so there is also an alteration of figures made by these motions . But you will say , it doth not follow , if Perception be made by Impression , that it must needs continue and not decay ; for if you touch and move a string , the motion doth not continue for ever , but ceaseth by degrees ; I answer , There is great difference between Prime self-motion , and forced or Artificial Motions ; for Artificial Motions are onely an Imitation of Natural Motions , and not the same , but caused by Natural Motions ; for although there is no Art that is not made by Nature , yet Nature is not made by Art ; Wherefore we cannot rationally judg of Perception by comparing it to the motion of a string , and its alteration to the ceasing of that motion , for Nature moveth not by force , but freely . 'T is true , 't is the freedom in Nature for one man to give another a box on the Ear , or to trip up his heels , or for one or more men to fight with each other ; yet these actions are not like the actions of loving Imbraces and Kissing each other ; neither are the actions one and the same , when a man strikes himself , and when he strikes another ; and so is likewise the action of impression , and the action of self-figuring not one and the same , but different ; for the action of impression is forced , and the action of self-figuring is free ; Wherefore the comparison of the forced motions of a string , rope , watch , or the like , can have no place here ; for though the rope , made of flax or hemp , may have the perception of a Vegetable , yet not of the hand , or the like , that touched or struck it ; and although the hand doth occasion the rope to move in such a manner , yet it is not the motion of the hand , by which it moveth , and when it ceases , its natural and inherent power to move is not lessened ; like as a man , that hath left off carving or painting , hath no less skill then he had before , neither is that skill lost when he plays upon the Lute or Virginals , or plows , plants , and the like , but he hath onely altered his action , as from carving to painting , or from painting to playing , and so to plowing and planting , which is not through disability but choice . But you will say , it is nevertheless a cessation of such a motion . I grant it : but the ceasing of such a motion is not the ceasing of self-moving matter from all motions , neither is cessation as much as annihilation , for the motion lies in the power of the matter to repeat it , as oft it will , if it be not overpowred , for more parts , or more strength , or more motions may over-power the less ; Wherefore forced , or artificial and free Natural motions are different in their effects , although they have but one Cause , which is the self-moving matter , and though Matter is but active and passive , yet there is great Variety , and so great difference in force and liberty , objects and perceptions , sense and reason , and the like . But to conclude , perception is not made by the pressure of objects , no more then hemp is made by the Rope-maker , or metal by the Bell-founder or Ringer , and yet neither the rope nor the metal is without sense and reason , but the natural motions of the metal , and the artificial motions of the Ringer are different ; wherefore a natural effect in truth cannot be produced from an artificial cause , neither can the ceasing of particular forced or artificial motions be a proof for the ceasing of general , natural , free motions , as that matter it self should cease to move ; for there is no such thing as rest in Nature , but there is an alteration of motions and figures in self-moving matter , which alteration causeth variety as well in opinions , as in every thing else ; Wherefore in my opinion , though sense alters , yet it doth not decay , for the rational and sensitive part of matter is as lasting as matter it self , but that which is named decay of sense , is onely the alteration of motions , and not an obscurity of motions , like as the motions of memory and forgetfulness , and the repetition of the same motions is called remembrance . And thus much of this subject for the present , to which I add no more but rest

YOur Authour discoursing of Imagination , saith , * * Leviathan , part. 1. c. 2. That as soon as any object is removed from our Eyes , though the Impression that is made in us , remain , yet other objects more present succeeding and working on us , the Imagination of the past is obscured and made weak . To which I answer , first , that he conceives Sense and Imagination to be all one , for he says , Imagination is nothing else , but a fading or decaying sense ; whereas in my opinion they are different , not onely their matter , but their motions also being distinct and different ; for Imagination is a rational perception , and sense a sensitive perception ; wherefore as much as the rational matter differs from the sensitive , as much doth Imagination differ from Sense . Next I say , that Impressions do not remain in the body of sensitive matter , but it is in its power to make or repeat the like figures ; Neither is Imagination less , when the object is absent , then when present , but the figure patterned out in the sensitive organs , being altered , and remaining onely in the Rational part of matter , is not so perspicuous and clear , as when it was both in the Sense and in the Mind : And to prove that Imagination of things past doth not grow weaker by distance of time , as your Authour says , many a man in his old age , will have as perfect an Imagination of what is past in his younger years , as if he saw it present . And as for your Authours opinion , that Imagination and Memory are one and the same , I grant , that they are made of one kind of Matter ; but although the Matter is one and the same , yet several motions in the several parts make Imagination and Memory several things : As for Example , a Man may Imagine that which never came into his Senses , wherefore Imagination is not one and the same thing with Memory . But your Author seems to make all Sense , as it were , one Motion , but not all Motion Sense , whereas surely there is no Motion , but is either Sensitive or Rational ; for Reason is but a pure and refined Sense , and Sense a grosser Reason . Yet all sensitive and rational Motions are not one and the same ; for forced or Artificial Motions , though they proceed from sensitive matter , yet are they so different from the free and Prime Natural Motions , that they seem , as it were , quite of another nature : And this distinction neglected is the Cause , that many make Appetites and Passions , Perceptions and Objects , and the like , as one , without any or but little difference . But having discoursed of the difference of these Motions in my former Letter , I will not be tedious to you , with repeating it again , but remain ,

VII . MADAM ,

YOur Authours opinion , concerning Dreams * * Leviathan , Part. 1. c. 2. , seemeth to me in some part very rational and probable , in some part not ; For when he sayes , that Dreams are onely Imaginations of them that sleep , which imaginations have been before either totally or by parcels in the Sense ; and that the organs of Sense , as the Brain and the Nerves , being benumb'd in sleep , as not easily to be moved by external objects , those Imaginations proceed onely from the agitation of the inward parts of mans body , which for the connexion they have with the Brain , and other organs , when they be distemper'd , do keep the same in motion , whereby the Imaginations there formerly made , appear as if a man were waking ; This seems to my Reason not very probable : For , first , Dreams are not absolutely Imaginations , except we do call all Motions and Actions of the Sensitive and Rational Matter , Imaginations . Neither is it necessary , that all Imaginations must have been before either totally or by parcels in the Sense ; neither is there any benumbing of the organs of Sense in sleep . But Dreams , according to my opinion , are made by the Sensitive and Rational Corporeal Motions , by figuring several objects , as awake ; onely the difference is , that the Sensitive motions in Dreams work by rote and on the inside of the Sensitive organs , when as awake they work according to the patterns of outward objects , and exteriously or on the outside of the sensitive Organs , so that sleep or dreams are nothing else but an alteration of motions , from moving exteriously to move interiously , and from working after a Pattern to work by rote : I do not say that the body is without all exterior motions , when asleep , as breathing and beating of the Pulse ( although these motions are rather interior then exterior , ) but that onely the sensitive organs are outwardly shut , so as not to receive the patterns of outward Objects , nevertheless the sensitive Motions do not cease from moving inwardly , or on the inside of the sensitive Organs ; But the rational matter doth often , as awake , so asleep or in dreams , make such figures , as the sensitive did never make either from outward objects , or of its own accord ; for the sensitive hath sometimes liberty to work without Objects , but the Rational much more , which is not bound either to the patterns of Exterior objects , or of the sensitive voluntary Figures . Wherefore it is not divers distempers , as your Authour sayes , that cause different Dreams , or Cold , or Heat ; neither are Dreams the reverse of our waking Imaginations , nor all the Figures in Dreams are not made with their heels up , and their heads downwards , though some are ; but this error or irregularity proceeds from want of exterior Objects or Patterns , and by reason the sensitive Motions work by rote ; neither are the Motions reverse , because they work inwardly asleep , and outwardly awake , for Mad-men awake see several Figures without Objects . In short , sleeping and waking is somewhat after that manner , when men are called either out of their doors , or stay within their houses ; or like a Ship , where the Mariners work all under hatches , whereof you will find more in my Philosophical Opinions ; and so taking my leave , I rest

YOur Author going on in his discourse of Imagination , says , a a Leviathan , part. 1. c. 3. That , as we have no Imagination , whereof we have not formerly had sense , in whole or in parts ; so we have not Transition from one Imagination to another , whereof we never had the like before in our senses . To which my answer is in short , that the Rational part of Matter in one composed figure , as in Man , or the like Creature , may make such figures , as the senses did never make in that composed Figure or Creature ; And though your Authour reproves those that say , b b part. 1. c. 2. Imaginations rise of themselves ; yet , if the self-moving part of Matter , which I call Rational , makes Imaginations , they must needs rise of themselves ; for the Rational part of matter being free and self-moving , depends upon nothing , neither Sense nor Object , I mean , so , as not to be able to work without them . Next , when your Author , defining Vnderstanding , says that it is nothing else , but c c Ibid. c. 3. an Imagination raised by words or other voluntary signs , My Answer is , that Understanding , and so Words and Signs are made by self-moving Matter , that is , Sense and Reason , and not Sense and Reason by Words and Signs ; wherefore Thoughts are not like d d ibid. Water upon a plain Table , which is drawn and guided by the finger this or that way , for every Part of self-moving matter is not alwayes forced , perswaded or directed , for if all the Parts of Sense and Reason were ruled by force or perswasion , not any wounded Creature would fail to be healed , or any disease to be cured by outward Applications , for outward Applications to Wounds and Diseases might have more force , then any Object to the Eye : But though there is great affinity and sympathy between parts , yet there is also great difference and antipathy betwixt them , which is the cause that many objects cannot with all their endeavours work such effects upon the Interiour parts , although they are closely press'd , for Impressions of objects do not always affect those parts they press . Wherefore , I am not of your Author's opinion , that all Parts of Matter press one another ; It is true , Madam , there cannot be any part single , but yet this doth not prove , that parts must needs press each other : And as for his Train of Thoughts , I must confess , that Thoughts for the most part are made orderly , but yet they do not follow each other like Geese , for surely , man has sometimes very different thoughts ; as for Example , a man sometime is very sad for the death of his Friend , and thinks of his own death , and immediately thinks of a wanton Mistress , which later thought , surely , the thought of Death did not draw in ; wherefore , though some thought may be the Ring-leader of others , yet many are made without leaders . Again , your Author in his description of the Mind sayes , that the discourse of the mind , when it it is govern'd by design , is nothing but seeking , or the Faculty of Invention ; a hunting out of the Causes of some Effects , present or past ; or of the Effects of some present or past Cause . Sometimes a man seeks what he has lost , and from that Place and Time wherein he misses it , his mind runs back from place to place , and time to time , to find where and when he had it , that is to say , to find some certain and limited Time and Place , in which to begin a method of Seeking . And from thence his thoughts run over the same places and times to find what action or other occasion might make him lose it . This we call Remembrance or calling to mind . Sometimes a man knows a place determinate , within the compass whereof he is to seek , and then his thoughts run over all the Parts thereof in the same manner as one would sweep a room to find a Jewel , or as a Spaniel ranges the field till he find a sent ; or as a Man should run over the Alphabet to start a Rime . Thus far your Author : In which discourse I do not perceive that he defineth what the Mind is , but I say , that if , according to his opinion , nothing moves it self , but one thing moves another , then the Mind must do nothing , but move backward and forward , nay , onely forward , and if all actions were thrusting or pressing of parts , it would be like a crowd of People , and there would be but little or no motion , for the crowd would make a stoppage , like water in a glass , the mouth of the Glass being turned downwards , no water can pass out , by reason the numerous drops are so closely press'd , as they cannot move exteriously . Next , I cannot conceive how the Mind can run back either to Time or Place , for as for Place , the mind is inclosed in the body , and the running about in the parts of the body or brain will not inform it of an Exterior place or object ; besides , objects being the cause of the minds motion , it must return to its Cause , and so move until it come to the object , that moved it first , so that the mind must run out of the body to that object , which moved it to such a Thought , although that object were removed out of the World ( as the phrase is : ) But for the mind to move backward , to Time past , is more then it can do ; Wherefore in my opinion , Remembrance , or the like , is onely a repetition of such Figures as were like to the Objects ; and for Thoughts in Particular , they are several figures , made by the mind , which is the Rational Part of matter , in its own substance , either voluntarily , or by imitation , whereof you may see more in my Book of Philosophical Opinions . Hence I conclude , that Prudence is nothing else , but a comparing of Figures to Figures , and of the several actions of those Figures , as repeating former Figures , and comparing them to others of the like nature , qualities , proprieties , as also chances , fortunes , &c. Which figuring and repeating is done actually , in and by the Rational Matter , so that all the observation of the mind on outward Objects is onely an actual repetition of the mind , as moving in such or such figures and actions ; and when the mind makes voluntary Figures with those repeated Figures , and compares them together , this comparing is Examination ; and when several Figures agree and joyn , it is Conclusion or Judgment : likewise doth Experience proceed from repeating and comparing of several Figures in the Mind , and the more several Figures are repeated and compared , the greater the experience is . One thing more there is in the same Chapter , which I cannot let pass without examination ; Your Authour says , That things Present onely have a being in Nature , things Past onely a being in the Memory , but things to come have no being at all ; Which how it possibly can be , I am not able to conceive ; for certainly , if nothing in nature is lost or annihilated , what is past , and what is to come , hath as well a being , as what is present ; and , if that which is now , had its being before , why may it not also have its being hereafter ? It might as well be said , that what is once forgot , cannot be remembred ; for whatsoever is in Nature , has as much a being as the Mind , and there is not any action , or motion , or figure , in Nature , but may be repeated , that is , may return to its former Figure , when it is altered and dissolved ; But by reason Nature delights in variety , repetitions are not so frequently made , especially of those things or creatures , which are composed by the sensitive corporeal motions in the inanimate part of Matter , because they are not so easily wrought , as the Rational matter can work upon its own parts , being more pliant in its self , then the Inanimate matter is ; And this is the reason , that there are so many repetitions of one and the same Figure in the Rational matter , which is the Mind , but seldom any in the Gross and inanimate part of Matter , for Nature loves ease and freedom : But to conclude , Madam , I perceive your Author confines Sense onely to Animal-kind , and Reason onely to Man-kind : Truly , it is out of self-love , when one Creature prefers his own Excellency before another , for nature being endued with self-love , all Creatures have self-love too , because they are all Parts of Nature ; and when Parts agree or disagree , it is out of Interest and Self-love ; but Man herein exceeds all the rest , as having a supernatural Soul , whose actions also are supernatural , To which I leave him , and rest ,

WHen your Author discourseth of the use of Speech or Words and Names , he is pleas'd to say , * * Leviathan , part. 1. c. 4. That their use is to serve for marks and notes of Remembrance ; Whereof to give you my opinion , I say , That Speech is natural to the shape of Man ; and though sometimes it serves for marks or notes of remembrance , yet it doth not always , for all other Animals have Memory without the help of Speech , and so have deaf and dumb men , nay more then those that hear and speak : Wherefore , though Words are useful to the mind , and so to the memory , yet both can be without them , whereas Words cannot be without Memory ; for take a Bird and teach him to speak , if he had not Memory , before he heard the words , he could never learn them . You will ask me , Madam , What then , is Memory the Cause of Speech ? I answer , Life and Knowledg , which is Sense and Reason , as it creates and makes all sorts of Creatures , so also amongst the rest it makes Words : And as I said before , that Memory may be without the help of Speech or Words , so I say also , that there is a possibility of reckoning of numbers , as also of magnitudes , of swiftness , of force , and other things without words , although your Author denies it : But some men are so much for Art , as they endeavour to make Art , which is onely a Drudgery-maid of Nature , the chief Mistress , and Nature her Servant , which is as much as to prefer Effects before the Cause , Nature before God , Discord before Unity and Concord .

Again , your Author , in his Chapter of Reason Ch. 5. , defines Reason to be nothing else but Reckoning : I answer , That in my opinion Reckoning is not Reason it self , but onely an effect or action of Reason ; for Reason , as it is the chiefest and purest degree of animate matter , works variously and in divers motions , by which it produces various and divers effects , which are several Perceptions , as Conception , Imagination , Fancy , Memory , Remembrance , Understanding , Judgment , Knowledg , and all the Passions , with many more : Wherefore this Reason is not in one undivided part , nor bound to one motion , for it is in every Creature more or less , and moves in its own parts variously ; and in some Creatures , as for example , in some men , it moves more variously then in others , which is the cause that some men are more dull and stupid , then others ; neither doth Reason always move in one Creature regularly , which is the cause , that some men are mad or foolish : And though all men are made by the direction of Reason , and endued with Reason , from the first time of their birth , yet all have not the like Capacities , Understandings , Imaginations , Wits , Fancies , Passions , &c. but some more , some less , and some regular , some irregular , according to the motions of Reason or Rational part of animate matter ; and though some rational parts may make use of other rational Parts , as one man of another mans Conceptions , yet all these parts cannot associate together ; as for example , all the Material parts of several objects , no not their species , cannot enter or touch the eye without danger of hurting or loosing it , nevertheless the eye makes use of the objects by patterning them out , and so doth the rational matter ; by taking patterns from the sensitive ; And thus knowledg or perception of objects , both sensitive and rational , is taken without the pressure of any other parts ; for though parts joyn to parts , ( for no part can be single ) yet this joining doth not necessarily infer the pressure of objects upon the sensitive organs ; Whereof I have already discoursed sufficiently heretofore , to which I refer you , and rest

UNderstanding , says your Author , * * Leviathan , part. 1. c. 4. is nothing else but Conception caused by speech , and therefore , if speech be peculiar to man , ( as , for ought I know , it is ) then is understanding peculiar to him also . Where he confineth Understanding onely to speech and to Mankind ; But , by his leave , Madam , I surely believe , that there is more understanding in Nature , then that , which is in speech , for if there were not , I cannot conceive , how all the exact forms in Generations could be produced , or how there could be such distinct degrees of several sorts and kinds of Creatures , or distinctions of times and seasons , and so many exact motions and figures in Nature : Considering all this , my reason perswadeth me , that all Understanding , which is a part of Knowledg , is not caused by speech , for all the motions of the Celestial Orbs are not made by speech , neither is the knowledg or understanding which a man hath , when sick , as to know or understand he is sick , made by speech , nor by outward objects , especially in a disease he never heard , nor saw , nor smelt , nor tasted , nor touched ; Wherefore all Perception , Sensation , Memory , Imagination , Appetite , Understanding , and the like , are not made nor caused by outward objects , nor by speech . And as for names of things , they are but different postures of the figures in our mind or thoughts , made by the Rational matter ; But Reasoning is a comparing of the several figures with their several postures and actions in the Mind , which joyned with the several words , made by the sensitive motions , inform another distinct and separate part , as an other man , of their minds conceptions , understanding , opinions , and the like .

Concerning Addition and Substraction , wherein your Author sayes Reasoning consists , I grant , that it is an act of Reasoning , yet it doth not make Sense or Reason , which is Life and Knowledge , but Sense and Reason which is self-motion , makes addition and substraction of several Parts of matter ; for had matter not self-motion , it could not divide nor compose , nor make such varieties , without great and lingring retardments , if not confusion . Wherefore all , what is made in Nature , is made by self-moving matter , which self-moving matter doth not at all times move regularly , but often irregularly , which causes false Logick , false Arithmetick , and the like ; and if there be not a certainty in these self-motions or actions of Nature , much less in Art , which is but a secundary action ; and therefore , neither speech , words , nor exterior objects cause Understanding or Reason . And although many parts of the Rational and Sensitive Matter joyned into one , may be stronger by their association , and over-power other parts that are not so well knit and united , yet these are not the less pure ; onely these Parts and Motions being not equal in several Creatures , make their Knowledge and Reason more or less : For , when a man hath more Rational Matter well regulated , and so more Wisdom then an other , that same man may chance to over-power the other , whose Rational Matter is more irreregular , but yet not so much by strength of the united Parts , as by their subtilty ; for the Rational Matter moving regularly , is more strong with subtilty , then the sensitive with force ; so that Wisdom is stronger then Life , being more pure , and so more active ; for in my opinion , there is a degree of difference between Life and Knowledge , as my Book of Philosophical Opinions will inform you .

Again , your Author sayes , That Man doth excel all other Animals in this faculty , that when he conceives any thing whatsoever , he is apt to enquire the Consequences of it , and what effects he can do with it : Besides this ( sayes he ) Man hath an other degree of Excellence , that he can by Words reduce the Consequences he finds to General Rules called Theoremes or Aphorisms , that is , he can reason or reckon not onely in Number , but in all other things , whereof one may be added unto , or substracted from an other . To which I answer , That according to my Reason I cannot perceive , but that all Creatures may do as much ; but by reason they do it not after the same manner or way as Man , Man denies , they can do it at all ; which is very hard ; for what man knows , whether Fish do not Know more of the nature of Water , and ebbing and flowing , and the saltness of the Sea ? or whether Birds do not know more of the nature and degrees of Air , or the cause of Tempests ? or whether Worms do not know more of the nature of Earth , and how Plants are produced ? or Bees of the several sorts of juices of Flowers , then Men ? And whether they do not make there Aphorismes and Theoremes by their manner of Intelligence ? For , though they have not the speech of Man , yet thence doth not follow , that they have no Intelligence at all . But the Ignorance of Men concerning other Creatures is the cause of despising other Creatures , imagining themselves as petty Gods in Nature , when as Nature is not capable to make one God , much less so many as Mankind ; and were it not for Mans supernatural Soul , Man would not be more Supreme , then other Creatures in Nature , But ( says your Author ) this Priviledge in Man is allay'd by another , which is , No living Creature is subject to absurdity , but onely Man . Certainly , Madam , I believe the contrary , to wit , that all other Creatures do as often commit mistakes and absurdities as Man , and if it were not to avoid tediousness , I could present sufficient proofs to you : Wherefore I think , not onely Man but also other Creatures may be Philosophers and subject to absurdities as aptly as Men ; for Man doth , nor cannot truly know the Faculties , and Abilities or Actions of all other Creatures , no not of his own Kind as Man-Kind , for if he do measure all men by himself he will be very much mistaken , for what he conceives to be true or wise , an other may conceive to be false and foolish . But Man may have one way of Knowledge in Philosophy and other Arts ; and other Creatures another way , and yet other Creatures manner or way may be as Intelligible and Instructive to each other as Man 's , I mean , in those things which are Natural . Wherefore I cannot consent to what your Author says , That Children are not endued with Reason at all , till they have attained to the use of Speech ; for Reason is in those Creatures which have not Speech , witness Horses , especially those which are taught in the manage , and many other Animals . And as for the weak understanding in Children , I have discoursed thereof in my Book of Philosophy ; The rest of this discourse , lest I tyre you too much at once , I shall reserve for the next , resting in the mean time ,

MADAM , Your faithful Friend , and Servant .
XI . MADAM ,

I sent you word in my last , that your Author's opinion is , That Children are not endued with Reason at all , until they have attained to the use of Speech , in the same Chapter * * Ch. 4. he speaks to the same purpose thus : Reason is not as Sense and Memory born with us , nor gotten by experience onely , as Prudence is , but attained by industry . To which I reply onely this , That it might as well be said , a Child when new born hath not flesh and blood , because by taking in nourishment or food , the Child grows to have more flesh and blood ; or , that a Child is not born with two legs , because he cannot go , or with two arms and hands , because he cannot help himself ; or that he is not born with a tongue , because he cannot speak : For although Reason doth not move in a Child as in a Man , in Infancy as in Youth , in Youth as in Age , yet that doth not prove that Children are without Reason , because they cannot run and prate : I grant , some other Creatures appear to have more Knowledg when new born then others ; as for example , a young Foal has more knowledg than a young Child , because a Child cannot run and play ; besides a Foal knows his own Dam , and can tell where to take his food , as to run and suck his Dam , when as an Infant cannot do so , nor all beasts , though most of them can , but yet this doth not prove , that a Child hath no reason at all ; Neither can I perceive that man is a Monopoler of all Reason , or Animals of all Sense , but that Sense and Reason are in other Creatures as well as in Man and Animals ; for example , Drugs , as Vegetables and Minerals , although they cannot slice , pound or infuse , as man can , yet they can work upon man more subtilly , wisely , and as sensibly either by purging , vomiting , spitting , or any other way , as man by mincing , pounding and infusing them , and Vegetables will as wisely nourish Men , as Men can nourish Vegetables ; Also some Vegetables are as malicious and mischievous to Man , as Man is to one another , witness Hemlock , Nightshade , and many more ; and a little Poppy will as soon , nay sooner cause a Man to sleep , though silently , then a Nurse a Child with singing and rocking ; But because they do not act in such manner or way as Man , Man judgeth them to be without sense and reason ; and because they do not prate and talk as Man , Man believes they have not so much wit as he hath ; and because they cannot run and go , Man thinks they are not industrious ; the like for Infants concerning Reason . But certainly , it is not local motion or speech that makes sense and reason , but sense and reason makes them ; neither is sense and reason bound onely to the actions of Man , but it is free to the actions , forms , figures and proprieties of all Creatures ; for if none but Man had reason , and none but Animals sense , the World could not be so exact , and so well in order as it is : but Nature is wiser then Man with all his Arts , for these are onely produced through the variety of Natures actions , and disputes through the superfluous varieties of Mans follies or ignorances , not knowing Natures powerful life and knowledg : But I wonder , Madam , your Author says in this place , That Reason is not born with Man , when as in another place , * * In his Elements of Philosophy , part. 1. c. 1. art. 1. he says , That every man brought Philosophy , that is Natural reason with him into the World ; Which how it agree , I will leave to others to judg , and to him to reconcile it , remaining in the mean time ,

TWo sorts of motions , I find your Author * * Leviathan , part. 1. c. 6. doth attribute to Animals , viz. Vital and Animal , the Vital motions , says he , are begun in Generation , and continued without Interruption through their whole life , aud those are the Course of the Blood , the Pulse , the Breathing , Conviction , Nutrition , Excretion , &c. to which motions there needs no help of Imaginations ; But the animal Motions , otherwise called voluntary Motions , are to go , to speak , to move any of our limbs , in such manner as is first fancied in our minds : And because going , speaking , and the like voluntary motions , depend always upon a precedent thought of whither , which way , and what , it is evident , that the Imagination is the first Internal beginning of all voluntary Motion . Thus far your Author . Whereof in short I give you my opinion , first concerning Vital Motions , that it appears improbable if not impossible to me , that Generation should be the cause and beginning of Life , because Life must of necessity be the cause of Generation , life being the Generator of all things , for without life motion could not be , and without motion not any thing could be begun , increased , perfected , or dissolved . Next , that Imagination is not necessary to Vital Motions , it is probable it may not , but yet there is required Knowledg , which I name Reason ; for if there were not Knowledg in all Generations or Productions , there could not any distinct Creature be made or produced , for then all Generations would be confusedly mixt , neither would there be any distinct kinds or sorts of Creatures , nor no different Faculties , Proprieties , and the like . Thirdly , concerning Animal Motions , which your Author names Voluntary Motions , as to go , to speak , to move any of our limbs , in such manner as is first fancied in our minds , and that they depend upon a precedent thought of whither , which way , and what , and that Imagination is the first Internal beginning of them ; I think , by your Authors leave , it doth imply a contradiction , to call them Voluntary Motions , and yet to say they are caused and depend upon our Imagination ; for if the Imagination draws them this way , or that way , how can they be voluntary motions , being in a manner forced and necessitated to move according to Fancy or Imagination ? But when he goes on in the same place and treats of Endeavour , Appetite , Desire , Hunger , Thirst , Aversion , Love , Hate , and the like , he derives one from the other , and treats well as a Moral Philosopher ; but whether it be according to the truth or probability of Natural Philosophy , I will leave to others to judge , for in my opinion Passions and Appetites are very different , Appetites being made by the motions of the sensitive Life , and Passions , as also Imagination , Memory , &c. by the motions of the rational Life , which is the cause that Appetites belong more to the actions of the Body then the Mind : T is true , the Sensitive and Rational self-moving matter doth so much resemble each other in their actions , as it is difficult to distinguish them . But having treated hereof at large in my other Philosophical Work , to cut off repetitions , I will refer you to that , and desire you to compare our opinions together : But certainly there is so much variety in one and the same sort of Passions , and so of Appetites , as it cannot be easily express'd . To conclude , I do not perceive that your Author tells or expresses what the cause is of such or such actions , onely he mentions their dependance , which is , as if a man should converse with a Nobleman's Friend or Servant , and not know the Lord himself . But leaving him for this time , it is sufficient to me , that I know your Ladyship , and your Ladyship knows me , that I am ,

HAving obey'd your Commands in giving you my opinion of the First Part of the Book of that famous and learned Author you sent me , I would go on ; but seeing he treats in his following Parts of the Politicks , I was forced to stay my Pen , because of these following Reasons . First , That a Woman is not imployed in State Affairs , unless an absolute Queen . Next , That to study the Politicks , is but loss of Time , unless a man were sure to be a Favourite to an absolute Prince . Thirdly , That it is but a deceiving Profession , and requires more Craft then Wisdom . All which considered , I did not read that part of your Author : But as for his Natural Philosophy , I will send you my opinion so far as I understand it : For what belongs to Art , as to Geometry , being no Scholar , I shall not trouble my self withal . And so I 'l take my leave of you , when I have in two or three words answered the Question you sent me last , which was , Whether Nature be the Art of God , Man the Art of Nature , and a Politick Government the Art of Man ? To which I answer , T is probable it may be so ; onely I add this , That Nature doth not rule God , nor Man Nature , nor Politick Government Man ; for the Effect cannot rule the Cause , but the Cause doth rule the Effect : Wherefore if men do not naturally agree , Art cannot make unity amongst them , or associate them into one Politick Body and so rule them ; But man thinks he governs , when as it is Nature that doth it , for as nature doth unite or divide parts regularly or irregularly , and moves the several minds of men and the several parts of mens bodies , so war is made or peace kept : Thus it is not the artificial form that governs men in a Politick Government , but a natural power , for though natural motion can make artificial things , yet artificial things cannot make natural power ; and we might as well say , nature is governed by the art of nature , as to say man is ruled by the art and invention of men . The truth is , Man rules an artificial Government , and not the Government Man , just like as a Watch-maker rules his Watch , and not the Watch the Watch-maker . And thus I conclude and rest ,

COncerning the other Book of that learned Author Hobbs you sent me , called Elements of Philosophy , I shall likewise according to your desire , give you my judgment and opinion of it as I have done of the former , not that I intend to prejudice him any ways thereby , but onely to mark those places wherein I seem to dissent from his opinions , which liberty , I hope , he will not deny me ; And in order to this , I have read over the first Chapter of the mentioned Book , treating of Philosophy in General , wherein amongst the rest , discoursing of the Utility of Natural Philosophy , and relating the commodities and benefits which proceed from so many arts and sciences , he is pleased to say , Art. 7. that they are injoyed almost by all people of Europe , Asia , and some of Africa , onely the Americans , and those that live neer the Poles do want them : But why , says he , have they sharper wits then these ? Have not all men one kind of soul , and the same faculties of mind ? To which , give me leave , Madam , to add , That my opinion is , that there is a difference between the Divine and the Natural soul of man , and though the natural mind or soul is of one kind , yet being made of rational matter , it is divideable and composeable , by which division and composition , men may have more or less wit , or quicker and slower wit ; the like for Judgments , Imaginations , Fancies , Opinions , &c. For were the natural rational mind individeable , all men would have the like degree of wit or understanding , all men would be Philosophers or fools , which by reason they are not , it proves the natural rational mind is divideable and composeable , making variations of its own several parts by self-motion ; for it is not the several outward objects , or forreign instructions , that make the variety of the mind ; neither is wit or ingenuity alike in all men ; for some are natural Poets , Philosophers , and the like , without learning , and some are far more ingenious then others , although their breeding is obscure and mean , Neither will learning make all men Scholars , for some will continue Dunces all their life time ; Neither doth much experience make all men wise , for some are not any ways advanced in their wisdom by much and long experiences ; And as for Poetry , it is according to the common Proverb , a Poet is born , not made ; Indeed learning doth rather hurt Fancy , for great Scholars are not always good Poets , nor all States-men Natural Philosophers , nor all Experienced Men Wise Men , nor all Judges Just , nor all Divines Pious , nor all Pleaders or Preachers Eloquent , nor all Moral Philosophers Vertuous ; But all this is occasioned by the various Motions of the rational self-moving matter , which is the Natural Mind . And thus much for the present of the difference of wits and faculties of the mind ; I add no more , but rest ,

MY Discourse for the present shall be of Infinite , and the question shall be first Whether several Finite parts , how many soever there be , can make an Infinite . Your Author says , * * Elem. of Philos. c. 7. a. 12. that several Finite parts when they are all put together make a whole Finite ; which , if his meaning be of a certain determinate number , how big soever , of finite parts , I do willingly grant , for all what is determinate and limited , is not Infinite but Finite ; neither is there any such thing , as Whole or All in Infinite ; but if his meaning be , that no Infinite can be made of finite parts , though infinite in number , I deny it ; Next he says there can be no such thing as One in Infinite , because No thing can be said One , except there be another to compare it withal ; which in my opinion doth not follow , for there is but One God , who is Infinite , and hath none other to be compared withal , and so there may be but one Onely Infinite in Nature , which is Matter . But when he says , there cannot be an Infinite and Eternal Division , is very true , viz , in this sense , that one single part cannot be actually infinitely divided , for the Compositions hinder the Divisions in Nature , and the Divisions the Compositions , so that Nature , being Matter , cannot be composed so , as not to have parts , nor divided so , as that her parts should not be composed , but there are nevertheless infinite divided parts in Nature , and in this sense there may also be infinite divisions , as I have declared in my Book of Philosophy . P. 1. c. 8. And thus there are Infinite divisions of Infinite parts in Nature , but not Infinite actual divisions of one single part ; But though Infinite is without end , yet my discourse of it shall be but short and end here , though not my affection , which shall last and continue with the life of

AN Accident , says your Author , * * Elem. of Philos c. 8. ●rt . 2. is nothing else , but the manner of our Conception of body , or that Faculty of any body , by which it works in us a Conception of it self ; To which I willingly consent ; but yet I say , that these qualities cannot be separated from the body , for as impossible it is that the essence of Nature should be separable from Nature , as impossible is it that the various modes or alterations , either of Figures or Motions , should be separable from matter or body ; Wherefore when he goes on , and says , An accident is not a body , but in a body , yet not so , as if any thing were Art. 3. contained therein , as it for example , redness were in blood in the same manner as blood is in a bloody cloth ; but as magnitude is in that which is great , rest in that which resteth , motion in that which is moved ; I answer , that in my opinion , not any thing in Nature can be without a body , and that redness is as well in blood , as blood is in a bloody cloth , or any other colour in any thing else ; for there is no colour without a body , but every colour hath as well a body as any thing else , and if Colour be a separable accident , I would faih know , how it can be separated from a subject , being bodiless , for that which is no body is nothing , and nothing cannot be taken away from any thing ; Wherefore as for natural Colour it cannot be taken away from any creature , without the parts of its substance or body ; and as for artificial Colours , when they are taken away , it is a separation of two bodies , which joyned together ; and if Colour , or Hardness , or Softness do change , it is nothing else but an alteration of motions and not an annihilation , for all changes and alterations remain in the power of Corporeal motions , as I have said in other places ; for we might as well say , life doth not remain in nature , when a body turns from an animal to some other figure , as believe that those , they name accidents , do not remain in Corporeal Motions ; Wherefore I am not of your Authors mind , when he says , * * Art. 20. that when a White thing is made black , the whiteness perishes ; for it cannot perish , although it is altered from white to black , being in the power of the same matter , to turn it again from black to white , so as it may make infinite Repetitions of the same thing ; but by reason nature takes delight in variety , she seldom uses such repetitions ; nevertheless that doth not take away the Power of self-moving matter , for it doth not ; and it cannot , are two several things , and the latter doth not necessarily follow upon the former ; Wherefore not any , the least thing , can perish in Nature , for if this were possible , the whole body of nature might perish also , for if so many . Fugures and Creatures should be annihilated and perish without any supply or new Creation , Nature would grow less , and at last become nothing ; besides it is as difficult for Nature to turn something into nothing , as to Create something out of nothing ; Wherefore as there is no annihilation or perishing in Nature , so there is neither any new Creation in Nature . But your Author makes a difference between bodies and accidents , saying , that bodies are things and not Generated , but accidents are Generated and not things , Truly , Madam , these accidents seem to me to be like Van Helmont's Lights , Gases , Blazes and Ideas ; and Dr More 's Immaterial Substances or Daemons , onely in this Dr More hath the better , that his Immaterial Substances , are beings , which subsist of themselves , whereas accidents do not , but their existence is in other bodies ; But what they call Accidents , are in my opinion nothing else but Corporeal Motions , and if these accidents be generated , they must needs be bodies , for how nothing can be Generated in nature , is not conceivable , and yet your Author denies , a a Art. 2. that Accidents are something , namely some part of a natural thing ; But as for Generations , they are onely various actions of self-moving matter , or a variety of Corporeal Motions , and so are all Accidents whatsoever , so that there is not any thing in nature , that can be made new , or destroyed , for whatsoever was and shall be , is in nature , though not always in act , yet in power , as in the nature and power of Corporeal motions , which is self-moving matter , And as there is no new Generation of Accidents , so there is neither a new Generation of Motions ; wherefore when your Author says , b b Art. 21. That , when the hand , being moved , moveth the pen , the motion doth not go out of the hand into the pen , for so the writing might be continued , though the hand stood still , but a new motion is generated in the pen , and is the pens motion : I am of his opinion , that the motion doth not go out of the hand into the pen , and that the motion of the pen , is the pens own motion ; but I deny , that after holding the hand a little while still , and beginning to write again , a new motion of the pen is generated ; for it is onely a repetition , and not a new generation , for the Hand , Pen and Ink , repeat but the same motion or action of writing : Besides , Generation is made by Connexion or Conjunction of parts , moving by consent to such or such Figures , but the motion of the Hand or the Pen is always one and the same ; wherefore it is but the variation and repetition in and of the same motion of the Hand , or Pen , which may be continued in that manner infinitely , just as the same Corporeal Motions can make infinite variations and repetitions of one and the same Figure , repeating it as oft as they please , as also making Copy of Copy ; And although I do not deny , but there are Generations in Nature , yet not annihilations or perishings , for if any one motion or figure should perish , the matter must perish also ; and if any one part of matter can perish , all the matter in nature may perish also ; and if there can any new thing be made or created in nature , which hath not been before , there may also be a new Nature , and so by perishings and new Creations , this World would not have continued an age ; But surely whatsoever is in Nature , hath been existent always . Wherefore to conclude , it is not the generation and perishing of an Accident that makes its subject to be changed , but the production and alteration of the Form , makes it said to be generated or destroyed , for matter will change its motions and figures without perishing or annihilating ; and whether there were words or not , there would be such causes and effects ; But having not the art of Logick to dispute with artificial words , nor the art of Geometry to demonstrate my opinions by Mathematical Figures , I fear they will not be so well received by the Learned ; However , I leave them to any mans unprejudiced Reason and Judgment , and devote my self to your service , as becomes ,

YOur Author concerning Place and Magnitude says , that Place is nothing out of the mind , nor Part. 2. c. 8. a. 5. Magnitude any thing within it ; for Place is a meer Phantasme of a body of such quantity and figure , and Magnitude a peculiar accident of the body ; But this doth not well agree with my reason , for I believe that Place , Magnitude and Body are but one thing , and that Place is as true an extension as Magnitude , and not a feigned one ; Neither am I of his opinion , that Place is Immoveable , but that place moves , according as the body moveth , for not any body wants place , because place and body is but one thing , and wheresoever is body , there is also place , and wheresoever is place , there is body , as being one and the same ; Wherefore Motion cannot be a relinquishing of one place and acquiring another , Art. 10. for there is no such thing as place different from body , but what is called change of place , is nothing but change of corporeal motions ; for , say an house stands in such a place , if the house be gone , the place is gone also , as being impossible that the place of the house should remain , when the house is taken away ; like as a man when he is gone out of his chamber , his place is gone too ; T is true , if the ground or foundation do yet remain , one may say , there stood such an house heretofore , but yet the place of the house is not there really at that present , unless the same house be built up again as it was before , and then it hath its place as before ; Nevertheless the house being not there , it cannot be said that either place or house are annihilated , viz , when the materials are dissolved , no not when transformed into millions of several other figures , for the house remains still in the power of all those several parts of matter ; and as for space , it is onely a distance betwixt some parts or bodies ; But an Empty place signifies to my opinion Nothing , for if place and body are one and the same , and empty is as much as nothing , then certainly these two words cannot consist together , but are destructive to one another . Concerning , that your Author says ; Two bodies cannot be together in the same place , nor Art. 8. one body in two places at the same time , is very true , for there are no more places then bodies , nor more bodies then places , and this is to be understood as well of the grosser , as the purest parts of nature , of the mind as well as of the body , of the rational and sensitive animate matter as well as of the inanimate , for there is no matter , how pure and subtil soever , but is imbodied , and all that hath body hath place . Likewise I am of his opinion , That one body hath always one and the same Art. 5. magnitude ; for , in my opinion , magnitude , place and body do not differ , and as place , so magnitude can never be separated from body . But when he speaks of Rest , I cannot believe there is any such thing truly in Nature , for it is impossible to prove , that any thing is without Motion , either consistent , or composing , or dissolving , or transforming motions , or the like , although not altogether perceptible by our senses , for all the Matter is either moving or moved , and although the moved parts are not capable to receive the nature of self-motion from the self-moving parts , yet these self-moving parts , being joyned and mixt with all other parts of the moved matter , do always move the same ; for the Moved or Inanimate part of Matter , although it is a Part of it self , yet it is so intermixt with the self-moving Animate Matter , as they make but one Body ; and though some parts of the Inanimate may be as pure as the Sensitive Animate Matter , yet they are never so subtil as to be self-moving ; Wherefore the Sensitive moves in the Inanimate , and the Rational in the Sensitive , but often the Rational moves in it self . And , although there is no rest in nature , nevertheless Matter could have been without Motion , when as it is impossible that Matter could be without place or magnitude , no more then Variety can be without motion ; And thus much at this present : I conclude , and rest ,

PAssing by those Chapters of your Authors , that treat of Power and Act , Identy and Difference , Analogisme , Angle and Figure , Figures deficient , dimension of Circles , and several others , most of which belong to art , as to Geometry , and the like ; I am come to that wherein he discourses of Sense and Animal Motion , saying , That some Natural bodies have in themselves the patterns almost of all things , and others of none C. 25. a. 1. at all ; Whereof my opinion is , that the sensitive and rational parts of Matter are the living and knowing parts of Nature , and no part of nature can challenge them onely to it self , nor no creature can be sure , that sense is onely in Animal-kind , and reason in Man-kind ; for can any one think or believe that Nature is ignorant and dead in all her other parts besides Animals ? Truly this is a very unreasonable opinion ; for no man , as wise as he thinks himself , nay were all Man-kind joyned into one body , yet they are not able to know it , unless there were no variety of parts in nature , but onely one whole and individeable body , for other Creatures may know and perceive as much as Animals , although they have not the same Sensitive Organs , nor the same manmer or way of Perception . Next your Author says , The cause of Sense or Perception consists herein , that the first organ of sense is touched and pressed ; For when the Art. 2. uttermost part of the organ is pressed , it no sooner yields , but the part next within it is pressed also , and in this manner the pressure or motion is propagated through all the parts of the organ to the innermost . And thus also the pressure of the uttermost part proceeds from the pressure of some more remote body , and so continually , till we come to that , from which , as from its fountain , we derive the Phantasme or Idea , that is made in us by our sense : And this , whatsoever it be , is that we commonly call the object ; Sense therefore is some Internal motion in the Sentient , Generated by some Internal motion of the Parts of the object , and propagated through all the media to the innermost part of the organ . Moreover there being a resistance or reaction in the organ , by reason of its internal motion against the motion propagated from the object , there is also an endeavour in the organ opposite to the endeavour proceeding from the object , and when that endeavour inwards is the last action in the act of sense , then from the reaction a Phantasme or Idea has its being . This is your Authors opinion , which if it were so , perception could not be effected so suddenly , nay I think the sentient by so many pressures in so many perceptions , would at last be pressed to death , besides the organs would take a great deal of hurt , nay totally be removed out of their places , so as the eye would in time be prest into the centre of the brain ; And if there were any Resistance , Reaction or Indeavour in the organ , opposite to the Endeavour of the object , there would , in my opinion , be always a war between the animal senses and the objects , the endeavour of the objects pressing one way , and the senses pressing the other way , and if equal in their strengths , they would make a stop , and the sensitive organs would be very much pained ; Truly , Madam , in my opinion , it would be like that Custom which formerly hath been used at Newcastle , when a man was married , the guests divided themselves , behind and before the Bridegroom ; the one party driving him back , the other forwards , so that one time a Bridegroom was killed in this fashion ; But certainly Nature hath a more quick and easie way of giving intelligence and knowledg to her Creatures , and doth not use such constraint and force in her actions ; Neither is sense or sensitive perception a meer Phantasme or Idea , but a Corporeal action of the sensitive and rational matter , and according to the variation of the objects or patterns , and the sensitive and rational motions , the perception also is various , produced not by external pressure , but by internal self-motion , as I have declared heretofore ; and to prove , that the sensitive and rational corporeal motions are the onely cause of perception ; I say , if those motions in an animal move in another way , and not to such perceptions , then that animal can neither hear , see , taste , smell , nor touch , although all his sensitive organs be perfect , as is evident in a man falling into a swoon , where all the time he is in a swoon , the pressure of the objects is made without any effect ; Wherefore , as the sensitive and rational corporeal motions make all that is in nature , so likewise they make perception , as being perception it self , for all self-motion is perception , but all perception is not animal perception , or after an animal way ; and therefore sense cannot decay nor die ; but what is called a decay or death , is nothing else but a change or alteration of those Motions : But you will say , Madam , it may be , that one body , as an object , leaves the print of its figure , in the next adjoyning body , until it comes to the organ of sense , I answer that then sost bodies onely must be pressed , and the object must be so hard as to make a print , and as for rare parts of matter , they are not able to retain a print without self-motion ; Wherefore it is not probable that the parts of air should receive a print , and print the same again upon the adjoyning part , until the last part of the air print it upon the eye ; and that the exterior parts of the organ should print upon the interior , till it come to the centre of the Brain , without self-motion . Wherefore in my opinion , Perception is not caused either by the printing of objects , nor by pressures , for pressures would make a general stop of all natural motions , especially if there were any reaction or resistence of sense ; but according to my reason , the sensitive and rational corporeal motions in one body , pattern out the Figure of another body , as of an exterior object , which may be done easily without any pressure or reaction ; I will not say , that there is no pressure or reaction in Nature , but pressure and reaction doth not make perception , for the sensitive and rational parts of matter make all perception and variety of motion , being the most subtil parts of Nature , as self-moving , as also divideable , and composeable , and alterable in their figurative motions , for this Perceptive matter can change its substance into any figure whatsoever in nature , as being not bound to one constant figure . But having treated hereof before , and being to say more of it hereaster , this shall suffice for the present , remaining always ,

TO discourse of the World and Stars , is more then I am able to do , wanting the art of Astronomy and Geometry ; wherefore passing by that Chapter of your Author , I am come to that * * Ch. 27. wherein he treats of Light , Heat and Colours ; and to give you my opinion of Light , I say , it is not the light of the Sun , that makes an Animal see , for we can see inwardly in Dreams without the Suns light , but it is the sensitive and rational Motions in the Eye and Brain that make such a figure as Light ; For if Light did press upon the Eye , according to your Authors opinion , it might put the Eye into as much pain as Fire doth , when it sticks its points into our skin or flesh . The same may be said of Colours , for the sensitive motions make such a figure , which is such a Colour , and such a Figure , which is such a Colour ; Wherefore Light , Heat and Colour , are not bare and bodiless qualities ; but such figures made by corporeal self-motions , and are as well real and corporeal objects as other figures are ; and when these figures change or alter , it is onely that their motions alter , which may alter and change heat into cold , and light into darkness , and black colour into white . But by reason the motions of the Sun are so constant , as the motions of any other kind of Creatures , it is no more subject to be altered then all the World , unless Nature did it by the command of God ; for though the Parts of self-moving Matter be alterable , yet all are not altered ; and this is the reason , that the figure of Light in our eye and brain is altered , as well as it is alterable , but not the real figure of the Sun , neither doth the Sun enter our eyes ; and as the Light of the Sun is made or patterned in the eye , so is the light of Glow-worms-tails , and Cats-eyes , that shine in the dark , made not by the Sun 's , but their own motions in their own parts ; The like when we dream of Light , the sensitive corporeal motions working inwardly , make the figure of light on the inside of the eye , as they did pattern out the figure of light on the out side of the eye when awake , and the objects before them ; for the sensitive motions of the eye pattern out the figure of the object in the eye , and the rational motions make the same figure in their own substance . But there is some difference between those figures that perceive light , and those that are light themselves ; for when we sleep , there is made the figure of light , but not from a copy ; but when the eye seeth light , that figure is made from a copy of the real figure of the Sun ; but those lights which are inherent , as in Glow-worms-tails , are original lights , in which is as much difference as between a Man and his Picture ; and as for the swiftness of the Motions of light , and the violence of the Motions of fire , it is very probable they are so , but they are a certain particular kind or sort of swift and violent motions ; neither will all sorts of swift and violent motions make fire or light , as for example the swift and violent Circular motion of a Whirlewind neither makes light nor fire ; Neither is all fire light , nor all light fire , for there is a sort of dead fire , as in Spices , Spirits , Oyles , and the like ; and several sorts of lights , which are not hot , as the light which is made in Dreams , as also the inherent lights in Glow-worms , Cats-eyes , Fish-bones , and the like ; all which several fires and lights are made by the self-moving matter and motions distinguishable by their figures , for those Motions make such a figure for the Suns light , such a figure for Glow-worms light , such a figure for Cats-eyes light , and so some alteration in every sort of light ; The same for Fire , onely Fire-light is a mixt figure , as partly of the figure of Fire , and partly of the figure of Light : Also Colours are made after the like manner , viz. so many several Colours , so many several Figures ; and as these Figures are less or more different , so are the Colours .

Thus , Madam , whosoever will study Nature , must consider the Figures of every Creature , as well as their Motions , and must not make abstractions of Motion and Figure from Matter , nor of Matter from Motion and Figure , for they are inseparable , as being but one thing , viz. Corporeal Figurative Motions ; and whosoever conceives any of them as abstract , will , in my opinion , very much erre ; but men are apt to make more difficulties and enforcements in nature then nature ever knew . But to return to Light : There is no better argument to prove that all objects of sight are figured in the Eye , by the sensitive , voluntary or self-motions , without the pressure of objects , but that not onely the pressure of light would hurt the tender Eye , but that the eye doth not see all objects according to their Magnitude , but sometimes bigger , sometimes less : as for example , when the eye looks through a small passage , as a Prospective-glass , by reason of the difficulty of seeing a body through a small hole , and the double figure of the glass being convex and concave , the corporeal motions use more force , by which the object is enlarged , like as a spark of fire by force is dilated into a great fire , and a drop of water by blowing into a bubble ; so the corporeal motions do double and treble their strength , making the Image of the object exceeding large in the eye ; for though the eye be contracted , yet the Image in the eye is enlarged to a great extension ; for the sensitive and rational matter is extremely subtil , by reason it is extreamly pure , by which it hath more means and ways of magnifying then the Perspective-glass . But I intend to write more of this subject in my next , and so I break off here , resting ,

SOme perhaps will question the truth or probability of my saying , that Light is a Body , objecting that if light were a body , when the Sun is absent or retires under our Horizon , its light would leave an empty place , or if there were no empty place but all full , the light of the Sun at its return would not have room to display it self , especially in so great a compass as it doth , for two bodies cannot be in one place at one time . I answer , all bodies carry their places along with them , for body and place go together and are inseparable , and when the light of the Sun is gone , darkness succeeds , and when darkness is gone , light succeeds , so that it is with light and darkness as with all Creatures else ; For you cannot believe , that if the whole World were removed , there would be a place of the world left , for there cannot be an empty nothing , no more then there can be an empty something ; but if the world were annihilated , the place would be annihilated too , place and body being one and the same thing ; and therefore in my opinion , there be no more places then there are bodies , nor no more bodies then there are places .

Secondly , They will think it absurd that I say , the eye can see without light ; but in my opinion it seems not absurd , but very rational , for we may see in dreams , and some do see in the dark , not in their fancy or imagination , but really ; and as for dreams , the sensitive corporeal motions make a light on the inside of the organ of sight really , as I have declared in my former Letter . But that we do not see ordinarily without exterior Light , the reason is , that the sensitive Motions cannot find the outward objects to pattern out without exterior light , but all perception doth not proceed from light , for all other perception besides animal sight requires not light . Neither in my opinion , doth the Perception of sight in all Creatures but Animals , but yet Animals do often see in the dark , and in sleep : I will not say but that the animate matter which by self-motion doth make the Perception of light with other perceptive Figures , and so animal perceptive light may be the presenter or ground perceptive figure of sight ; yet the sensitive corporeal motions can make other figures without the help of light , and such as light did never present : But when the eye patterns out an exterior object presented by light , it patterns also out the object of light ; for the sensitive motions can make many figures by one act , not onely in several organs , but in one organ ; as for example , there is presented to sight a piece of Imbroydery , wherein is silk , silver and gold upon Sattin in several forms or figures , as several flowers , the sensitive motions streight by one and the same act , pattern out all those several figures of flowers , as also the figures of Silk , Silver , Gold and Sattin , without any pressure of these objects , or motions in the medium , for if they all should press , the eye would no more see the exterior objects , then the nose , being stopt , could smell a presented perfume ;

Thirdly , They may ask me , if sight be made in the eye , and proceeds not from the outward object , what is the reason that we do not see inwardly , but outwardly as from us ? I answer , when we see objects outwardly , as from us , then the sensitive motions work on the outside of the organ , which organ being outwardly convex , causes us to see outwardly , as from us , but in dreams we see inwardly ; also the sensitive motions do pattern out the distance together with the object : But you will say , the body of the distance , as the air , cannot be perceived , and yet we can perceive the distance ; I answer , you could not perceive the distance , but by such or such an object as is subject to your sight ; for you do not see the distance more then the air , or the like rare body , that is between grosser objects ; for if there were no stars , nor planets , nor clouds , nor earth , nor water , but onely air , you would not see any space or distance ; but light being a more visible body then air , you might figure the body of air by light , but so , as in an extensive or dilating way ; for when the mind or the rational matter conceives any thing that hath not such an exact figure , or is not so perceptible by our senses ; then the mind uses art , and makes such figures , which stand like to that ; as for example , to express infinite to it self , it dilates it parts without alteration , and without limitation or circumference ; Likewise , when it will conceive a constant succession of Time , it draws out its parts into the figure of a line ; and if eternity , it figures a line without beginning and end : But as for Immaterial , no mind can conceive that , for it cannot put it self into nothing , although it can dilate and rarifie it self to an higher degree , but must stay within the circle of natural bodies , as I within the circle of your Commands , to express my self ,

HEat and Cold , according to your Authors opinion , are made by Dilation and Contraction : for says he , When the Motion of the ambient aethereal C. 28. ● . 1. substance makes the spirits and fluid parts of our bodies tend outwards , we acknowledg heat , but by the indeavour inwards of the same spirits and humors we feel cold : so that to cool is to make the exterior parts of the body endeavour inwards , by a motion contrary to that of calefaction , by which the internal parts are called outwards . He therefore that would know the cause of Cold , must find by what motion the exterior parts of any body endeavour to retire inwards . But I desire you to consider , Madam , that there be moist Colds , and dry Heats , as well as dry Colds , and moist Heats ; wherefore all sorts of Cold are not made by the retyring of parts inwards , which is contraction or attraction ; neither are all sorts of Heat made by parts tending outwards , which is dilation or rarefaction ; for a moist cold is made by dilation , and a dry heat by contraction , as well as a moist heat is made by dilation , and a dry cold by contraction : But your Author makes not this difference , but onely a difference between a dilated heat , and a contracted cold ; but because a cold wind is made by breath blown thorow pinched or contracted lips , and an hot wind by breath through opened and extended lips , should we judg that all heat and cold must be made after one manner or way ? The contracted mouth makes Wind as well as the dilated , but yet Wind is not made that way , as heat and cold ; for it may be , that onely the air pressed together makes wind , or it may be that the corporeal motions in the air may change air into wind , as they change water into vapour , and vapour into air ; or it may be something else that is invisible and rare , as air ; and there may be several sorts of wind , air , heat , cold , as of all other Creatures , more then man is capable to know . As for your Authors opinion concerning the congealing of Water , and how Ice is made , I will not contradict it , onely I think nature hath an easier way to effect it , then he describes ; Wherefore my opinion is , that it is done by altering motions ; as for example , the corporeal motions making the figure of water by dilation in a Circle figure , onely alter from such a dilating circular figure into a contracted square , which is Ice , or into such a contracted triangle , as is snow : And thus water and vapour may be changed with ease , without any forcing , pressing , raking , or the like . The same may be said of hard and bent bodies ; and of restitution , as also of air , thunder and lightning , which are all done by an easie change of motion , and changing into such or such a figure is not the motion of Generation , which is to build a new house with old materials , but onely a Transformation ; I say a new house with old materials ; not that I mean there is any new Creation in nature , of any thing that was not before in nature ; for nature is not God , to make new beings out of nothing , but any thing may be called new , when it is altered from one figure into another . I add no more at this time , but rest ,

THe Generation of sound , according to your worthy Authors opinion , is as follows : As Vision , * * Ch. 29. a. 1. says he , so hearing is Generated by the medium , but but not in the same manner ; for sight is from pressure , that is , from an endeavour , in which there is no perceptible progression of any of the parts of the medium , but one part urging or thrusting on another , propagateth that action successively to any distance whatsoever ; where as the motion of the medium , by which sound is made , is a stroke ; for when we hear , the drum of the Ear , which is the first organ of hearing , is strucken , and the drum being stricken , the Pia Mater is also shaken , and with it the arteries inserted into it , by which the action propagated to the heart it self , by the reaction of the heart a Phantasme is made which we call Sound . Thus far your Author : To which give me leave to reply , that I fear , if the Ear was bound to hear any loud Musick , or another sound a good while , it would soundly be beaten , and grow sore and bruised with so many strokes ; but since a pleasant sound would be rendred very unpleasant in this manner , my opinion is , that like as in the Eye , so in the Ear the corporeal sensitive motions do pattern out as many several figures , as sounds are presented to them ; but if these motions be irregular , then the figure of the sound in the ear is not perfect according to the original ; for if it be , that the motions are tyred with figuring , or the object of sound be too far distant from the sensitive organ , then they move slowly and weakly , not that they are tyred or weak in strength , but with working and repeating one and the same object , and so through love to variety , change from working regularly to move irregularly , so as not to pattern outward objects as they ought , and then there are no such patterns made at all , which we call to be deaf ; and sometimes the sensitive motions do not so readily perceive a soft sound near , as a stronger farther off . But to prove it is not the outward object of sound with its striking or pressing motion , nor the medium , that causes this perception of sense , if there be a great solid body , as a wall , or any other partition betwixt two rooms , parting the object and the sensitive organ , so , as the sound is not able to press it , nevertheless the perception will be made ; And as for pipes to convey sounds , the perception is more fixt and perfecter in united then in dilated or extended bodies , and then the sensitive motions can make perfecter patterns ; for the stronger the objects are , the more perfect are the figures and patterns of the objects , and the more perfect is the perception . But when the sound is quite out of the ear , then the sensitive motions have altered the patterning of such figures to some other action ; and when the sound fadeth by degrees , then the figure or pattern alters by degrees ; but for the most part the sensitive corporeal motions alter according as the objects are presented , or the perception patterns out . Neither do they usually make figures of outward objects , if not perceived by the senses , unless through Irregularities as in Mad men , which see such and such things , when as these things are not neer , and then the sensitive motions work by rote , or after their own voluntary invention . As for Reflexion , it is a double perception , and so a double figure of one object ; like as many pictures of one man , where some are more perfect then others , for a copy of a copy is not so perfect as a copy of an original . But the recoyling of sound is , that the sensitive motions in the ear begin a new pattern , before they dissolved the former , so as there is no perfect alteration or change , from making to dissolving , but pattern is made upon pattern , which causes a confusion of figures , the one being neither perfectly finished , nor the other perfectly made . But it is to be observed , that not always the sensitive motions in the organs take their pattern from the original , but from copies ; as for example , the sensitive motions in the eye , pattern out the figure of an eye in a glass , and so do not take a pattern from the original it self , but by an other pattern , representing the figure of the eye in a Looking-glass ; The same doth the Ear , by patterning out Ecchoes , which is but a pattern of a pattern ; But when as a man hears himself speak or make a sound , then the corporeal sensitive motions in the Ear , pattern out the object or figure made by the motions of the tongue and the throat , which is voice ; By which we may observe , that there may be many figures made by several motions from one original ; as for example , the figure of a word is made in a mans mouth , then the copy of that figure is made in the ear , then in the brain , and then in the memory , and all this in one Man : Also a word being made in a mans mouth , the air takes a copy or many copies thereof ; but the Ear patterns them both out , first the original coming from the mouth , and then the copy made in the air , which is called an Eccho , and yet not any strikes or touches each others parts , onely perceives and patterns out each others figure . Neither are their substances the same , although the figures be alike ; for the figure of a man may be carved in wood , then cut in brass , then in stone , and so forth , where the figure may be always the same , although the substances which do pattern out the figure are several , viz. Wood , Brass , Stone , &c. and so likewise may the figure of a stone be figured in the fleshy substance of the Eye , or the figure of light or colour , and yet the substance of the Eye remains still the same ; neither doth the substantial figure of a stone , or tree , patterned out by the sensitive corporeal motions , in the flesh of an animal eye , change from being a vegetable or mineral , to an animal , and if this cannot be done by nature , much less by art ; for if the figure of an animal be carved in wood or stone , it doth not give the wood or stone any animal knowledg , nor an animal substance , as flesh , bones , blood , &c. no more doth the patterning or figuring of a Tree give a vegetable knowledg , or the substance of wood to the eye , for the figure of an outward object doth not alter the substance that patterns it out or figures it , but the patterning substance doth pattern out the figure , in it self , or in its own substance , so as the figure which is pattern'd , hath the same life and knowledg with the substance by and in which it is figured or pattern'd , and the inherent motions of the same substance ; and according as the sensitive and rational self-moving matter moves , so figures are made ; and thus we see , that lives , knowledges , motions and figures are all material , and all Creatures are indued with life , knowledg , motion and figure , but not all alike or after the same manner . But to conclude this discourse of perception of Sound , the Ear may take the object of sound afar off , as well as at a near distance ; not onely if many figures of the same sound be made from that great distance , but if the interposing parts be not so thick , close , or many as to hinder or obscure the object from the animal Perception in the sensitive organ ; for if a man lays his Ear near to the Ground , the Ear may hear at a far distance , as well as the Eye can see , for it may hear the noise of a troop afar off , perception being very subtil and active ; Also there may several Copies be made from the Original , and from the last Copy nearest to the Ear , the Ear may take a pattern , and so pattern out the noise in the organ , without any strokes to the Ear , for the subtil matter in all Creatures doth inform and perceive . But this is well to be observed , that the figures of objects are as soon made , as perceived by the sensitive motions in their work of patterning . And this is my Opinion concerning the Perception of Sound , which together with the rest I leave to your Ladyships and others wiser Judgment , and rest ,

I Perceive by your last , that you cannot well apprehend my meaning , when I say that the print or figure of a Body Printed or Carved , is not made by the motions of the body Printing or Carving it , but by the motions of the body or substance Printed or Carved ; for say you , Doth a piece of Wood carve it self , or a black Patch of a Lady cut its own figure by its own motions ? Before I answer you , Madam , give me leave to ask you this question , whether it be the motion of the hand , or the Instrument , or both , that print or carve such or such a body ? Perchance you will say , that the motion of the hand moves the Instrument , and the Instrument moves the Wood which is to be carved : Then I ask , whether the motion that moves the Instrument , be the Instruments , or the Hands ? Perchance you will say the Hands ; but I answer , how can it be the Hands motion , if it be in the Instrument ? You will say , perhaps , the motion of the hand is tranferred out of the hand into the instrument , and so from the instrument into the carved figure ; but give me leave to ask you , was this motion of the hand , that was transferred , Corporeal or Incorporeal ? If you say , Corporeal , then the hand must become less and weak , but if Incorporeal , I ask you , how a bodiless motion can have force and strength to carve and cut ? But put an Impossible proposition , as that there is an Immaterial motion , and that this Incorporeal motion could be transferred out of one body into another ; then I ask you , when the hand and instrument cease to move , what is become of the motion ? Perhaps you will say , the motion perishes or is annihilated , and when the hand and the instrument do move again , to the carving or cutting of the figure , then a new Incorporeal Motion is created ; Truly then there will be a perpetual creation and annihilation of Incorporeal motions , that is , of that which naturally is nothing ; for an Incorporeal being is as much as a natural No-thing , for Natural reason cannot know nor have naturally any perception or Idea of an Incorporeal being : besides , if the motion be Incorporeal , then it must needs be a supernatural Spirit , for there is not any thing else Immaterial but they , and then it will be either an Angel or a Devil , or the Immortal Soul of man ; but if you say it is the supernatural Soul , truly I cannot be perswaded that the supernatural Soul should not have any other imployment then to carve or cut prints , or figures , or move in the hands , or heels , or legs , or arms of a Man ; for other animals have the same kind of Motions , and then they might have a Supernatural Soul as well as Man , which moves in them . But if you say , that these tranferrable motions are material , then every action whereby the hand moves to the making or moving of some other body , would lessen the number of the motions in the hand , and weaken it , so that in the writing of one letter , the hand would not be able to write a second letter , at least not a third . But I pray , Madam , consider rationally , that though the Artificer or Workman be the occasion of the motions of the carved body , yet the motions of the body that is carved , are they which put themselves into such or such a figure , or give themselves such or such a print as the Artificer intended ; for a Watch , although the Artist or Watch-maker be the occasional cause that the Watch moves in such or such an artificial figure , as the figure of a Watch , yet it is the Watches own motion by which it moves ; for when you carry the Watch about you , certainly the Watch-makers hand is not then with it as to move it ; or if the motion of the Watch-makers hand be transferred into the Watch , then certainly the Watch-maker cannot make another Watch , unless there be a new creation of new motions made in his hands ; so that God and Nature would be as much troubled and concerned in the making of Watches , as in the making of a new World ; for God created this World in six days , and rested the seventh day , but this would be a perpetual Creation ; Wherefore I say that some things may be Occasional causes of other things , but not the Prime or Principal causes ; and this distinction is very well to be considered , for there are no frequenter mistakes then to confound these two different causes , which make so many confusions in natural Philosophy ; and this is the Opinion of ,

IN answer to your question , What makes Eccho , I say , it is that which makes all the effects of Nature , viz. self-moving matter ; I know , the common opinion is , that Eccho is made like as the figure of a Face , or the like , in a Looking-glass , and that the Reverberation of sound is like the Reflection of sight in a Looking-glass ; But I am not of that opinion , for both Eccho , and that wich is called the Reflection in a Looking-glass , are made by the self-moving matter , by way of patterning and copying out . But then you will ask me , whether the glass takes the copy of the face , or the face prints its copy on the glass , or whether it be the medium of light and air that makes it ? I answer , although many Learned men say , that as all perception , so also the seeing of ones face in a Looking-glass , and Eccho , are made by impression and reaction ; yet I cannot in my simplicity conceive it , how bodies that come not near , or touch each other , can make a figure by impression and reaction : They say it proceeds from the motions of the Medium of light , or air , or both , viz. that the Medium is like a long stick with two ends , whereof one touches the object , the other the organ of sense , and that one end of it moving , the other moves also at the same point of Time , by which motions it may make many several figures ; But I cannot conceive , how this motion of pressing forward and backward should make so many figures , wherein there is so much variety and curiosity . But , say light and air are as one figure , and like as a seal do print another body ; I answer , if any thing could print , yet it is not probable , that so soft and rare bodies as light and air , could print such solid bodies as glass , nor could air by reverberation make such a sound as Eccho . But mistake me not , for , I do not say , that the Corporeal motions of light or air , cannot , or do not pencil , copie , or pattern out any figure , for both light and air are very active in such sorts of Motions , but I say , they cannot do it on any other bodies but their own . But to cut off tedious and unnecessary disputes , I return to the expressing of my own opinion , and believe , that the glass in its own substance doth figure out the copy of the face , or the like , and from that copy the sensitive motions in the eyes take another copy , and so the rational from the sensitive ; and in this manner is made both rational and sensitive perception , sight and knowledg . The same with Ecchoes ; for the air patterns out the copy of the sound , and then the sensitive corporeal motions in the ear pattern again this copy from the air , and so do make the perception and sense of hearing . You may ask me , Madam , if it be so , that the glass and the air copy out the figure of the face and of sound , whether the Glass may be said to see and the Air to speak ? I answer , I cannot tell that ; for though I say , that the air repeats the words , and the glass represents the face , yet I cannot guess what their perceptions are , onely this I may say , that the air hath an elemental , and the glass a mineral , but not an animal perception . But if these figures were made by the pressures of several objects or parts , and by reaction , there could not be such variety as there is , for they could but act by one sort of motion : Likewise is it improbable , that sounds , words or voices , should like a company of Wild-Geese fly in the air , and so enter into the ears of the hearers , as they into their nests : Neither can I conceive , how in this manner a word can enter so many ears , that is , be divided into every ear , and yet strike every ear with an undivided vocal sound ; You will say , as a small fire doth heat and warm all those that stand by ; for the heat issues from the fire , as the light from the Sun . I answer , all what issues and hath motion , hath a Body , and yet most learned men deny that sound , light and heat have bodies : But if they grand of light that it has a body , they say it moves and presses the air , and the air the eye , and so of heat ; which if so , then the air must not move to any other motion but light , and onely to one sort of light , as the Suns light ; for if it did move in any other motion , it would disturb the light ; for if a Bird did but fly in the air , it would give all the region of air another motion , and so put out , or alter the light , or at least disturb it ; and wind would make a great disturbance in it . Besides , if one body did give another body motion , it must needs give it also substance , for motion is either something or nothing , body or no body , substance or no substance ; if nothing , it cannot enter into another body ; if something , it must lessen the bulk of the body it quits , and increase the bulk of the body it enters , and so the Sun and Fire with giving light and heat , would become less , for they cannot both give and keep at once , for this is as impossible , as for a man to give to another creature his human Nature , and yet to keep it still . Wherefore my opinion is for heat , that when many men stand round about a fire , and are heated and warmed by it , the fire doth not give them any thing , nor do they receive something from the fire , but the sensitive motions in their bodies pattern out the object of the fires heat , and so they become more or less hot according as their patterns are numerous or perfect ; And as for air , it patterns out the light of the Sun , and the sensitive motions in the eyes of animals pattern out the light in the air . The like for Ecchoes , or any other sound , and for the figures which are presented in a Looking-glass . And thus millions of parts or creatures may make patterns of one or more objects , and the objects neither give nor loose any thing . And this I repeat here , that my meaning of Perception may be the better understood , which is the desire of ,

I Perceive you are not fully satisfied with my former Letter concerning Eccho , and a figure presented in a Looking-glass ; for you say , how is it possible , if Eccho consists in the ears patterning out of a voice or sound , but that it will make a confusion in all the parts of the air ? My answer is , that I doe not say that Eccho is onely made by the patterning out of the voice or sound , but by repeating the same voice or sound , which repetition is named an Eccho , for millions of ears in animals may pattern out a voice or words , and yet never repeat them , and so may millions of parts of the air ; wherefore Eccho doth not consist in the bare patterning out , but in the repetition of the same sound or words , which are pattern'd out ; and so some parts of the air may at one and the same time pattern out a sound and not repeat it , and some may both pattern out , and repeat it , but some may neither pattern out , nor repeat it , and therefore the Repetition , not the bare Patterning out is called Eccho : Just as when two or more men do answer or mock each other , and repeat each others words , it is not necessary , if there were a thousand standers by , that they should all do the same . And as for the figure presented in a Looking-glass , I cannot conceive it to be made by pressure and reaction ; for although there is both pressure and reaction in nature , and those very frequent amongst natures Parts , yet they do neither make perception nor production . although both pressure and reaction are made by corporeal self-motions ; Wherefore the figure presented in a Looking-glass , or any other smooth glassie body , is , in my opinion , onely made by the motions of the Looking-glass , which do both pattern out ; and present the figure of an external object in the Glass : But you will say , why do not the motions of other bodies pattern out , and present the figures of external objects , as well as smooth glassie bodies do ? I answer , they may pattern out external objects , for any thing I know ; but the reason that their figures are not presented to our eyes , lies partly in the presenting subject it self , partly in our sight ; for it is observed , that two things are chiefly required in a subject that will present the figure of an external object ; first it must be smooth , even and glassie , next it must not be transparent : the first is manifest by experience ; for the subject being rough and uneven , will never be able to present such a figure ; as for example , A piece of steel rough and unpolished , although it may perhaps pattern out the figure of an external object , yet it will never present its figure , but as soon as it is polished , and made smooth and glassie , the figure is presently perceived . But this is to be observed , that smooth and glassie bodies do not always pattern out exterior objects exactly , but some better , some worse ; like as Painters have not all the same ingenuity ; neither do all eyes pattern out all objects exactly ; which proves that the perception of sight is not made by pressure and reaction , o : herwise there would be no difference , but all eyes would see alike , Next I say , it is observed , that the subject which will present the figure of an external object , must not be transparent ; the reason is , that the figure of Light being a substance of a piercing and penetrating quality , hath more force on transparent , then on other solid dark bodies , and so disturbs the figure of an external object pattern'd out in a transparent body , and quite over-masters it . But you wil say , you have found by experience , that if you hold a burning Candle before a Transparent-glass , although it be in an open Sun-light , yet the figure of light and flame of the Candle will clearly be seen in the Glass . I answer , that it is an other thing with the figure of Candle-light , then of a duskish or dark body ; for a Candle-light , though it is not of the same sort as the Suns light , yet it is of the same nature and quality , and therefore the Candle-light doth resist and oppose the light of the Sun , so that it cannot have so much power over it , as over the figures of other bodies patterned out and presented in Transparent-glass . Lastly , I say , that the fault often-times lies in the perceptive motions of our sight , which is evident by a plain and Concave-glass ; for in a plain Looking-glass , the further you go from it , the more your figure presented in the glass seems to draw backward ; and in a Concave-glass , the nearer you go to it , the more seems your figure to come forth : which effects are like as an house or tree appears to a Traveller ; for , as the man moves from the house or tree , so the house or tree seems to move from the man ; or like one that sails upon a Ship , who imagines that the Ship stands still , and the Land moves ; when as yet it is the Man and the Ship that moves , and not the House , or Tree , or the Land : so when a Man turns round in a quick motion , or when his head is dizzie , he imagines the room or place , where he is , turns round . Wherefore it is the Inherent Perceptive motions in the Eye , and not the motions in the Looking-glass , which cause these effects . And as for several figures that are presented in one glass , it is absurd to imagine that so many several figures made by so many several motions should touch the eye ; certainly this would make such a disturbance , if all figures were to enter or but to touch the eye , as the eye would not perceive any of them , at least not distinctly ; Wherefore it is most probable that the glass patterns out those figures , and the sensitive corporeal motions in the eye take again a pattern from those figures patterned out by the glass , and so make copies of copies ; but the reason why several figures are presented in one glass in several places , is , that two perfect figures cannot be in one point , nor made by one motion , but by several corporeal motions . Concerning a Looking-glass , made in the form or shape of a Cylinder , why it represents the figure of an external object in an other shape and posture then the object is , the cause is the shape and form of the Glass , and not the patterning motions in the Glass . But this discourse belongs properly to the Opticks , wherefore I will leave it to those that are versed in that Art , to enquire and search more after the rational truth thereof . In the mean time , my opinion is , that though the object is the occasion of the figure presented in a Looking-glass , yet the figure is made by the motions of the glass or body that presents it , and that the figure of the glass perhaps may be patterned out as much by the motions of the object in its own substance , as the figure of the object is patterned out and presented by the motions of the glass in its own body or substance . And thus I conclude and rest ,

SInce I mentioned in my last that Light did disturb the figures of External objects presented in Transparent bodies ; you were pleased to ask , Whether light doth penetrate transparent bodies ? I answer , for any thing I know , it may ; for when I consider the subtil , piercing and penetrating nature of light , I believe it doth ; but again , when I consider that light is presented to our sight by transparent bodies onely , and not by duskish and dark bodies , and yet that those duskish bodies are more porous then the transparent bodies , so that the light hath more passage to pass through them , then through transparent bodies ; but that on the contrary , those dark bodies , as Wood , and the like , do quite obscure the light , when as transparent bodies , as Glass , &c. transmit it , I am half perswaded that the transparent bodies , as Glass , rather present the Light by patterning it out , then by giving it passage : Also I am of a mind , that the air in a room may pattern out the Light from the Glass , for the Light in a room doth not appear so clear as in the Glass ; also if the Glass be any way defective , it doth not present the Light so perfectly , whereas , if it were the penetration of light through the glass , the light would pass through all sorts of glass alike , which it doth not , but is more clearly seen through some , and more obscurely through others , according to the goodness or purity of the glass . But you may say , that the light divulges the imperfection or goodness of the glass ; I answer , so it doth of any other objects perceived by our sight ; for light is the presenter of objects to the sense and perception of sight , and for any thing I know , the corporeal optick motions make the figure of light , the ground figure of all other figures patterned out by the corporeal optick motions , as in dreams , or when as some do see in the dark , that is , without the help of exterior light . But you may say , That if the glass and the air in a room did pattern out the figure of light , those patterns of light would remain when light is absent : I answer , That is not usual in nature ; for when the object removes , the Pattern alters ; I will not say but that the corporeal optick motions may work by rote without objects , but that is irregular , as in some distempers . And thus , Madam , I have given you my opinion also to this your question ; if you have any more scruples , I pray let me know of them , and assure your self that I shall be ready upon all occasions to express my self ,

YOur desire is to know , why sound is louder in a Vault , and in a large Room then in a less ? I answer , A Vault or arched Figure is the freest from obstruction , as being without corners and points , so as the sensitive and rational corporeal motions of the Ear can have a better perception ; like as the Eye can see farthest from a hill then being upon a level ground , because the prospect is freer from the hill , as without obstruction , unless it be so cloudy that the clouds do hinder the perception ; And as the eye can have a better prospect upon a hill , so the ear a stronger perception in a Vault ; And as for sound , that it is better perceived in a large , then in a little close room or place , it is somewhat like the perception of sent , for the more the odorous parts are bruised , the stronger is that perception of sent , as being repeated double or treble , which makes the perception stronger , like as a thick body is stronger then a thin one ; So likewise the perception of sound in the air ; for though not all the parts of the air make repetitions , yet some or many make patterns of the sound ; the truth is , Air is as industrious to divulge or present a found , by patterns to the Ear , as light doth objects to the Eye . But then you may ask me , Why a long hollow pipe doth convey a voice to the ear more readily , then any large and open place ? My answer is , That the Parts of the air in a long pipe are more Composed and not at liberty to wander , so that upon necessity they must move onely to the patterning out of the sound , having no choice , which makes the sound much stronger , and the perception of the Ear perfecter ; But as for Pipes , Vaults , Prospects , as also figures presented in a room through a little hole , inverted , and many the like , belongs more to Artists then to my study , for though Natural Philosophy gives or points out the Ground , and shews the reason , yet it is the Artist that Works ; Besides it is more proper for Mathematicians to discourse of , which study I am not versed in ; and so leaving it to them , I rest ,

FRom Sound I am come to Sent , in the discourse whereof , your Author * * Ch. 29. art. 12. is pleased to set down these following propositions : 1. That smelling is hindred by cold and helped by heat : 2. That when the Wind bloweth from the object , the smell is the stronger , and when it blowes from the sentient towards the obiect , the weaker , which by experience is found in dogs , that follow thetrack of beasts by the Sent : 3. That such bodies as are last pervious to the fluid medium , yield less smell then such as are more pervious : 4. That such bodies as are of their own nature odorous , become yet more odorous , when they are bruised : 5. That when the breath is stopped ( at least in man ) nothing can be smelt : 6. That the Sense of smelling is also taken away by the stopping of the Nostrils , though the mouth be left open . To begin from the last , I say , that the nose is like the other sensitive organs , which if they be stopt , the corporeal sensitive motions cannot take copies of the exterior objects , and therefore must alter their action of patterning to some other , for when the eye is shut and cannot perceive outward objects then it works to the Sense of Touch , or on the inside of the organ to some phantasmes ; and so do the rest of the Senses . As for the stopping of breath , why it hinders the Sent , the cause is , that the nostrils and the mouth are the chief organs , to receive air and to let out breath : but though they be common passages for air and breath , yet taste is onely made in the mouth and tongue , and sent in the nose ; not by the pressure of meat , and the odoriferous object , but by patterning out the several figures or objects of sent and taste , for the nose and the mouth will smell and taste one , nay several things at the same time , like as the eye will see light , colour , and other objects at once , which I think can hardly be done by pressures ; and the reason is , that the sensitive motions in the sensitive organs make patterns of several objects at one time , which is the cause , that when flowers , and such like odoriferous bodies are bruised , there are as many figures made as there are parts bruised or divided , and by reason of so many figures the sensitive knowledg is stronger ; but that stones , minerals , and the like , seem not so strong to our smell , the reason is , that their parts being close and united , the sensitive motions in the organ cannot so readily perceive and pattern them out , as those bodies which are more porous and divided . But as for the wind blowing the sent either to or from the sentient , it is like a window or door that by the motion of opening and shutting , hinders or disturbeth the sight ; for bodies coming between the object and the organ , make a stop of that perception . And as for the Dogs smelling out the track of Beasts , the cause is , that the earth or ground hath taken a copy of that sent , which copy the sensitive motions in the nose of the Dog do pattern out , and so long as that figure or copy lasts , the Dog perceives the sent , but if he doth not follow or hunt readily , then there is either no perfect copy made by the ground , or otherwise he cannot find it , which causes him to seek and smell about until he hath it ; and thus smell is not made by the motion of the air , but by the figuring motions in the nose : Where it is also to be observed , that not onely the motions in one , but in millions of noses , may pattern out one little object at one time , and therefore it is not , that the object of sent fills a room by sending out the sent from its substance , but that so many figures are made of that object of sent by so many several sensitive motions , which pattern the same out ; and so the air , or ground , or any other creature , whose sensitive motions pattern out the object of sent , may perceive the same , although their sensitive organs are not like to those of animal creatures ; for if there be but such sensitive motions and perceptions , it is no matter for such organs . Lastly , it is to be observed , That all Creatures have not the same strength of smelling , but some smell stronger , some weaker , according to the disposition of their sensitive motions : Also there be other parts in the body , which pattern out the object of sent , besides the nose , but those are interior parts , and take their patterns from the nose as the organ properly designed for it ; neither is their resentment the same , because their motions are not alike , for the stomack may perceive and pattern out a sent with aversion , when the nose may pattern it out with pleasure . And thus much also of Sent ; I conclude and rest ,

COncerning your Learned Authors discourse of Density and Rality , he defines * * C. 30. a. 1. Thick to be that , which takes up more parts of a space given ; and thin , which containes fewer parts of the same magnitude : not that there is more matter in one place then in an other equal place , but a greater quantity of some named body ; wherefore the multitude and paucity of the parts contained within the same space do constitute density and rarity . Where of my opinion is , That there is no more nor less space or place then body according to its ' dilation or contraction , and that space and place are dilated and contracted with the body , according to the magnitude of the body , for body , place and magnitude are the same thing , only place is in regard of the several parts of the body , and there is as well space betwixt things distant a hairs breadth from one another , as betwixt things distant a million of miles , but yet this space is nothing from the body ; but it makes , that that body has not the same place with this body , that is , that this body is not that body , and that this bodies place is not that bodies place . Next your Author sayes , * * Art. 2. He hath already clearly enough demonstrated , that there can be no beginning of motion , but from an external and moved body , and that heavy bodies being once cast upwards cannot be cast down again , but by external motion . Truly , Madam , I will not speak of your Authors demonstrations , for it is done most by art , which I have no knowledg in , but I think I have probably declared , that all the actions of nature are not forced by one part , driving , pressing , or shoving another , as a man doth a wheel-barrow , or a whip a horse ; nor by reactions , as if men were at foot-ball or cuffs , or as men with carts meeting each other in a narrow lane . But to prove there is no self-motion in nature , he goes on and says ; To attribute to created bodies the power to move themselves , what is it else , then to say that there be creatures which have no dependance upon the Creator ? To which I answer , That if man . ( who is but a single part of nature ) hath given him by God the power and a free will of moving himself , why should not God give it to Nature ? Neither can I see , how it can take off the dependance upon God , more then Eternity ; for if there be an Eternal Creator , there is also an Eternal Creature , and if an Eternal Master , an Eternal Servant , which is Nature ; and yet Nature is subject to Gods Command , and depends upon him ; and if all Gods Attributes be Infinite , then his Bounty is Infinite also , which cannot be exercised but by an Infinite Gift , but a Gift doth not cause a less dependance . I do not say , That man hath an absolute Free-will , or power to move , according to his desire ; for it is not conceived , that a part can have an absolute power : nevertheless his motion both of body and mind is a free and self-motion , and such a self-motion hath every thing in Nature according to its figure or shape ; for motion and figure , being inherent in matter , matter moves figuratively . Yet do I not say , That there is no hindrance , obstruction and opposition in nature ; but as there is no particular Creature , that hath an absolute power of self-moving ; so that Creature which hath the advantage of strength , subtilty , or policy , shape , or figure , and the like , may oppose and over-power another which is inferior to it , in all this ; yet this hinderance and opposition doth not take away self-motion . But I perceive your Author is much for necessitation , and against free-will , which I leave to Moral Philosophers and Divines . And as for the ascending of light , and descending of heavy bodies , there may be many causes , but these four are perceiveable by our senses , as bulk , or quantity of body , grossness of substance , density , and shape or figure , which make heavy bodies descend : But little quantity , purity of substance , rarity , and figure or shape make light bodies ascend . Wherefore I cannot believe , that there are certain little bodies as atoms , and by reason of their smallness , invisible , differing Art. 3. from one another in consistence , figure , motion and magnitude , intermingled with the air , which should be the cause of the descending of heavy bodies . And concerning air , whether it be subject to our senses or not , I say , that if air be neither hot , nor cold , it is not subject ; but Art. 14. if it be , the sensitive motions will soon pattern it out , and declare it . I 'le conclude with your Authors question , What Art. 6. the cause is , that a man doth not feel the weight of Water in Water ? and answer , it is the dilating nature of Water . But of this question and of Water I shall treat more fully hereafter , and so I rest ,

XXX . MADAM ,

I Am reading now the works of that Famous and most Renowned Author , Des Cartes , out of which I intend to pick out onely those discourses which I like best , and not to examine his opinions , as they go along from the beginning to the end of his books ; And in order to this , I have chosen in the first place , his discourse of motion , and do not assent to his opinion , Philos. p. 2. when he defines Motion to be onely a Mode of a thing , and not the thing or body it selfe ; for , in my opinion , Art. 2●● there can be no abstraction made of motion from body , neither really , nor in the manner of our conception , for how can I conceive that which is not , nor cannot be in nature , that is , to conceive motion without body ? Wherefore Motion is but one thing with body , without any separation or abstraction soever . Neither doth it agree with my reason , that one body can give or transferr Art. 40. motion into another body ; and as much motion it gives or transferrs into that body , as much loses it : As for example , in two hard bodies thrown against one another , where one , that is thrown with greater force , takes the other along with it , and loses as much motion as it gives it . For how can motion , being no substance , but onely a mode , quit one body , and pass into another ? One body may either occasion , or imitate anothers motion , but it can neither give nor take away what belongs to its own or another bodies substance , no more then matter can quit its nature from being matter ; and therefore my opinion is , that if motion doth go out of one body into another , then substance goes too ; for motion , and substance or body , as afore-mentioned , are all one thing , and then all bodies that receive motion from other bodies , must needs increase in their substance and quantity , and those bodies which impart or transferr motion , must decrease as much as they increase : Truly , Madam , that neither Motion nor Figure should subsist by themselves , and yet be transferrable into other bodies , is very strange , and as much as to prove them to be nothing , and yet to say they are something . The like may be said of all others , which they call accidents , as skill , learning , knowledge , &c. saying , they are no bodies , because they have no extension , but inherent in bodies or substances as in their subjects ; for although the body may subsist without them , yet they being always with the body , body and they are all one thing : And so is power and body , for body cannot quit power , nor power the body , being all one thing . But to return to Motion , my opinion is , That all matter is partly animate , and partly inanimate , and all matter is moving and moved , and that there is no part of Nature that hath not life and knowledg , for there is no Part that has not a comixture of animate and inanimate matter ; and though the inanimate matter has no motion , nor life and knowledg of it self , as the animate has , nevertheless being both so closely joyned and commixed as in one body , the inanimate moves as well as the animate , although not in the same manner ; for the animate moves of it self , and the inanimate moves by the help of the animate , and thus the animate is moving and the inanimate moved ; not that the animate matter transfers , infuses , or communicates its own motion to the inanimate ; for this is impossible , by reason it cannot part with its own nature , nor alter the nature of inanimate matter , but each retains its own nature ; for the inanimate matter remains inanimate , that is , without self-motion , and the animate loses nothing of its self-motion , which otherwise it would , if it should impart or transferr its motion into the inanimate matter ; but onely as I said heretofore , the inanimate works or moves with the animate , because of their close union and commixture ; for the animate forces or causes the inanimate matter to work with her ; and thus one is moving , the other moved , and consequently there is life and knowledg in all parts of nature , by reason in all parts of nature there is a commixture of animate and inanimate matter : and this Life and Knowledg is sense and reason , or sensitive and rational corporeal motions , which are all one thing with animate matter without any distinction or abstraction , and can no more quit matter , then matter can quit motion . Wherefore every creature being composed of this commixture of animate and inanimate matter , has also selfe-motion , that is life and knowledg , sense and reason , so that no part hath need to give or receive motion to or from another part ; although it may be an occasion of such a manner of motion to another part , and cause it to move thus or thus : as for example , A Watch-maker doth not give the watch its motion , but he is onely the occasion , that the watch moves after that manner , for the motion of the watch is the watches own motion , inherent in those parts ever since that matter was , and if the watch ceases to move after such a manner or way , that manner or way of motion is never the less in those parts of matter , the watch is made of , and if several other figures should be made of that matter , the power of moving in the said manner or mode , would yet still remain in all those parts of matter as long as they are body , and have motion in them . Wherefore one body may occasion another body to move so or so , but not give it any motion , but everybody ( though occasioned by another , to move in such a way ) moves by its own natural motion ; for self-motion is the very nature of animate matter , and is as much in hard , as in fluid bodies , although your Author denies it , saying , The nature of fluid bodies consists in the motion of those little insensible parts into which Philos. part. 2. a. 54. they are divided , and the nature of bard bodies , when those little particles joyned closely together , do rest ; for there is no rest in nature ; wherefore if there were a World of Gold , and a World of Air , I do verily believe , that the World of Gold would be as much interiously active , as the World of Air exteriously ; for Natures motions are not all external or perceptible by our senses , neither are they all circular , or onely of one sort , but there is an infinite change and variety of motions ; for though I say in my Philosophical opinions , * * Part. 1. c. 5. As there is but one onely Matter , so there is but one onely Motion ; yet I do not mean , there is but one particular sort of motions , as either circular , or straight , or the like , but that the nature of motion is one and the same , simple and intire in it self , that is , it is meer motion , or nothing else but corporeal motion ; and that as there are infinite divisions or parts of matter , so there are infinite changes and varieties of motions , which is the reason that I call motion as well infinite as matter ; first that matter and motion are but one thing , and if matter be infinite , motion must be so too ; and secondly , that motion is infinite in its changes and variations , as matter is in its parts . And thus much of motion for this time ; I add no more , but rest ,

I Observe your Author in his discourse of Place makes a difference betwixt an Interior and Exterior Philos. p. 2. a. 10 , 11 , 12 , 13 , 14. place , and that according to this distinction , one body may be said to change , and not to change its place at the same time , and that one body may succeed into anothers place . But I am not of this opinion , for I believe not that there is any more place then body ; as for example , Water being mix'd with Earth , the water doth not take the Earths place , but as their parts intermix , so do their places , and as their parts change , so do their places , so that there is no more place , then there is water and earth ; the same may be said of Air and Water , or Air and Earth , or did they all mix together ; for as their bodies join , so do their places , and as they are separated from each other , so are their places . Say a man travels a hundred miles , and so a hundred thousand paces ; but yet this man has not been in a hundred thousand places , for he never had any other place but his own , he hath joined and separated himselfe from a hundred thousand , nay millions of parts , but he has left no places behind him . You will say , if he travel the same way back again , then he is said to travel thorow the same places . I answer , It may be the vulgar way of expression , or the common phrase ; but to speak properly , after a Philosophical way , and according to the truth in nature , he cannot be said to go back again thorow the same places he went , because he left none behind him , or els all his way would be nothing but place after place , all the hundred miles along ; besides if place should be taken so , as to express the joyning to the neerest bodies which compass him about , certainly he would never find his places again ; for the air being fluid , changes or moves continually , and perchance the same parts of the air , which compassed him once , will never come near him again . But you may say , If a man be hurt , or hath some mischance in his body , so as to have a piece of flesh cut out , and new flesh growing there ; then we say , because the adjoyning parts do not change , that a new piece of flesh is grown in the same place where the former flesh was , and that the place of the former flesh cut or fallen out , is the same of this new grown flesh . I answer , In my opinion , it is not , for the parts being not the same , the places are not , but every one hath its own place . But if the wound be not filled or closed up with other new flesh , you will say , that according to my opinion there is no place then at all . I say , Yes , for the air or any thing else may be there , as new parts joyning to the other parts ; nevertheless , the air , or that same body which is there , hath not taken the fleshes place , which was there before , but hath its own ; but , by reason the adjoyning parts remain , man thinks the place remains there also which is no consequence . 'T is true , a man may return to the same adjoining bodies , where he was before , but then he brings his place with him again , and as his body , so his place returnes also , and if a mans arm be cut off , you may say , there was an arm heretofore , but you cannot say properly , this is the place where the arm was . But to return to my first example of the mixture of Water , and Earth or Air ; Suppose water is not porous , but onely dividable , and hath no other place but what is its own bodies ' , and that other parts of water intermix with it by dividing and composing ; I say , there is no more place required , then what belongs to their own parts , for if some contract , others dilate , some divide , others joyn , the places are the same according to the magnitude of each part or body . The same may be said of all kinds or sorts of mixtures , for one body hath but one place ; and so if many parts of the same nature joyn into one body and increase the bulk of the body , the place of that same body is accordingly ; and if they be bodies of different natures which intermix and joyne , each several keeps its place ; And so each body and each particular part of a body hath its place , for you cannot name body or part of a body , but you must also understand place to be with them , and if a point should dilate to a world , or a world contract to a point , the place would always be the same with the body . And thus I have declared my opinion of this subject , which I submit to the correction of your better judgment , and rest ,

IN my last , I hope , I have sufficiently declared my opinion , That to one body belongs but one place , and that no body can leave a place behind it , but wheresoever is body , there is place also . Now give me leave to examine this question : when a bodies figure is printed on snow , or any other fluid or soft matter , as air , water , and the like ; whether it be the body , that prints its own figure upon the snow , or whether it be the snow , that patterns the figure of the body ? My answer is , That it is not the body , which prints its figure upon the snow , but the snow that patterns out the figure of the body ; for if a seal be printed upon wax , 't is true , it is the figure of the seal , which is printed on the wax , but yet the seal doth not give the wax the print of its own figure , but it is the wax that takes the print or pattern from the seal , and patterns or copies it out in its own substance , just as the sensitive motions in the eye do pattern out the figure of an object , as I have declared heretofore . But you will say , perhaps , A body being printed upon snow , as it leaves its print , so it leaves also its place with the print in the snow . I answer , That doth not follow ; For the place remains still the bodies place , and when the body removes out of the snow , it takes its place along with it : Just like a man , whose picture is drawn by a Painter , when he goes away , he leaves not his place with his picture , but his place goes with his body ; and as the place of the picture is the place of the colour or paint , and the place of the copie of an exterior object patterned out by the sensitive corporeal motions is the place of the sensitive organ , so the place of the print in snow , is the snows place ; or else , if the print were the bodies place that is printed , and not the snow's , it might as well be said , that the motion and shape of a watch were not the motion and shape of the watch , but of the hand of him that made it . And as it is with snow , so it is with air , for a mans figure is patterned out by the parts and motions of the air , wheresoever he moveth ; the difference is onely , that air being a fluid body doth not retain the print so long , as snow or a harder body doth , but when the body removes , the print is presently dissolved . But I wonder much , your Author denies , that there can be two bodies in one place , and yet makes two places for one body , when all is but the motions of one body : Wherefore a man sailing in a Ship , cannot be said to keep place , and to change his place ; for it is not place he changes , but onely the adjoyning parts , as leaving some , and joyning to others ; and it is very improper , to attribute that to place which belongs to parts , and to make a change of place out of change of parts . I conclude , repeating once again , that figure and place are still remaining the same with body ; For example ; let a stone be beat to dust , and this dust be severally dispersed , nay , changed into numerous figures ; I say , as long as the substance of the stone remains in the power of those dispersed and changed parts , and their corporeal motions , the place of it continues also ; and as the corporeal motions change and vary , so doth place , magnitude and figure , together with their parts or bodies , for they are but one thing . And so I conclude , and rest ,

I Am absolutely of your Authors opinion , when he sayes , That all bodies of this Universe are of one and Philos. part. 3. a. 46. the same matter , really divided into many parts , and that these parts are diversly moved : But that these motions should be circular more then of any other sort , I cannot believe , although he thinks that this is the most probable way , to find out the causes of natural effects : for nature is not bound to one sort of motions more then to another , and it is but in vain to indeavour to know how , and by what motions God did make the World , since Creation is an action of God , and Gods actions are incomprehensible ; Wherefore his aethereal Whirlpooles , and little particles of matter , which he reduceth to three sorts and calls them the three elements of the Universe , their circular motions , several figures , shavings , and many the like , which you may better read , then I rehearse to you , are to my thinking , rather Fancies , then rational or probable conceptions : for how can we imagine that the Universe was set a moving as a Top by a Whip , or a Wheele by the hand of a Spinster , and that the vacuities were fill'd up with shavings ? for these violent motions would rather have disturbed and disordered Nature ; and though Nature uses variety in her motions or actions , yet these are not extravagant , nor by force or violence , but orderly , temperate , free , and easie , which causes me to believe , the Earth turns about rather then the Sun ; and though corporeal motions for variety make Whirl-winds , yet Whirl-winds are not constant , Neither can I believe that the swiftness of motion could make the matter more subtil and pure then it was by nature , for it is the purity and subtilty of the matter , that causes motion , and makes it swifter or slower , and not motion the subtilty and purity of matter ; motion being onely the action of matter ; and the self-moving part of matter is the working part of nature , which is wise , and knows how to move and form every creature without instruction ; and this self-motion is as much her own as the other parts of her body , matter and figure , and is one and the same with her self , as a corporeal , living , knowing , and inseparable being , and a part of her self . As for the several parts of matter , I do believe , that they are not all of one and the same bigness , nor of one and the same figure , neither do I hold their figures to be unalterable ; for if all parts in nature be corporeal , they are dividable , composable , and intermixable , and then they cannot be always of one and the same sort of figure ; besides nature would not have so much work if there were no change of figures : and since her onely action is change of motion , change of motion must needs make change of figures : and thus natural parts of matter may change from lines to points , and from points to lines , from squares to circles , and so forth , infinite ways , according to the change of motions ; but though they change their figures , yet they cannot change their matter ; for matter as it has been , so it remaines constantly in each degree , as the Rational , Sensitive and Inanimate , none becomes purer , none grosser then ever it was , notwithstanding the infinite changes of motions , which their figures undergo ; for Motion changes onely the figure , not the matter it self , which continues still the same in its nature , and cannot be altered without a confusion or destruction of Nature . And this is the constant opinion of ,

THat Rarefaction is onely a change of figure , according to your Authors opinion , is in my reason Philos. part. 2. a. 6 , 7. very probable ; but when he sayes , that in rarified bodies are little intervals or pores filled up with some other subtil matter , if he means that all rarified bodies are porous , I dissent from him ; for it is not necessary that all rarified bodies should be porous , and all hard bodies without pores : but if there were a probability of pores , I am of opinion , it would be more in dense and hard , than in rare and soft bodies ; as for example , rarifying and dilating motions are plaining , smoothing , spreading and making all parts even , which could not well be , if there were holes or pores ; Earth is dense and hard , and yet is porous , and flame is rare and dilating , and yet is not porous ; and certainly Water is not so porous as Earth . Wherefore pores , in my opinion , are according to the nature or form of the figure , and not according to the rarity or thinness , and density or thickness of the substance . As for his thin and subtil matter filling up the pores of porous bodies , I assent to your Author so farr , that I meane , thin and thick , or rare and dense substances are joyned and mixed together . As for plaining , smoothing and spreading , I do not mean so much artificial plaining and spreading ; as for example , when a piece of gold is beaten into a thin plate , and a board is made plain and smooth by a Joyners tool , or a napkin folded up is spread plain and even , although , when you observe these arts , you may judge somewhat of the nature of natural dilations ; for a folded cloth is fuller of creases then when plain , and the beating of a thin plate is like to the motion of dilation , which is to spread out , and the forme of rarifying is thinning and extending . I add onely this , that I am not of your Authors opinion , that Rest is the Cause or Glue which keeps the parts of dense or hard bodies together , but it is retentive motions . And so I conclude , resting ,

THat the Mind , according to your Authors opinion , is a substance really distinct from the body , and may be actually separated from it and subsist without it : If he mean the natural mind and soul of Man , not the supernatural or divine , I am far from his opinion ; for though the mind moveth onely in its own parts , and not upon , or with the parts of inanimate matter , yet it cannot be separated from these parts of matter , and subsist by its self , as being a part of one and the same matter the inanimate is of , ( for there is but one onely matter , and one kind of matter , although of several degrees , ) onely it is the self-moving part ; but yet this cannot impower it , to quit the same natural body , whose part it is . Neither can I apprehend , that the Mind 's or Soul's seat should be in the Glandula or kernel of the Brain , and there sit like a Spider in a Cobweb , to whom the least motion of the Cobweb gives intelligence of a Flye , which he is ready to assault , and that the Brain should get intelligence by the animal spirits as his servants , which run to and fro like Ants to inform it ; or that the Mind should , according to others opinions , be a light , and imbroidered all with Ideas , like a Heraulds Coat ; and that the sensitive organs should have no knowledg in themselves , but serve onely like peepingholes for the mind , or barn-dores to receive bundles of pressures , like sheaves of Corn ; For there being a thorow mixture of animate , rational and sensitive , and inanimate matter , we canot assign a certain seat or place to the rational , another to the sensitive , and another to the inanimate , but they are diffused and intermixt throughout all the body ; And this is the reason , that sense and knowledg cannot be bound onely to the head or brain : But although they are mixt together , nevertheless they do not lose their interior natures by this mixture , nor their purity and subtilty , nor their proper motions or actions , but each moves according to its nature and substance , without confusion ; The actions of the rational part in Man , which is the Mind or Soul , are called Thoughts , or thoughtful perceptions , which are numerous , and so are the sensitive perceptions ; for though Man , or any other animal hath but five exterior sensitive organs , yet there be numerous perceptions made in these sensitive organs , and in all the body ; nay , every several Pore of the flesh is a sensitive organ , as well as the Eye , or the Ear. But both sorts , as well the rational as the sensitive , are different from each other , although both do resemble another , as being both parts of animate matter , as I have mentioned before : Wherefore I 'le add no more , onely let you know , that I constantly remain ,

THat all other animals , besides man , want reason , your Author endeavours to prove in his discourse of method , where his chief argument is , That other animals cannot express their mind , thoughts or conceptions , either by speech or any other signs , as man can do : For , sayes he , it is not for want of the organs belonging to the framing of words , as we may observe in Parrats and Pies , which are apt enough to express words they are taught , but understand nothing of them . My answer is , That one man expressing his mind by speech or words to an other , doth not declare by it his excellency and supremacy above all other Creatures , but for the most part more folly , for a talking man is not so wise as a contemplating man . But by reason other Creatures cannot speak or discourse with each other as men , or make certain signs , whereby to express themselves as dumb and deaf men do , should we conclude , they have neither knowledge , sense , reason , or intelligence ? Certainly , this is a very weak argument ; for one part of a mans body , as one hand , is not less sensible then the other , nor the heel less sensible then the heart , nor the legg less sensible then the head , but each part hath its sense and reason , and so consequently its sensitive and rational knowledg ; and although they cannot talk or give intelligence to each other by speech , nevertheless each hath its own peculiar and particular knowledge , just as each particular man has his own particular knowledge , for one man's knowledge is not another man's knowledge ; and if there be such a peculiar and particular knowledg in every several part of one animal creature , as man , well may there be such in Creatures of different kinds and sorts : But this particular knowledg belonging to each creature , doth not prove that there is no intelligence at all betwixt them , no more then the want of humane Knowledg doth prove the want of Reason ; for reason is the rational part of matter , and makes perception , observation , and intelligence different in every creature , and every sort of creatures , according to their proper natures , but perception , observation and intelligence do not make reason , Reason being the cause , and they the effects . Wherefore though other Creatures have not the speech , nor Mathematical rules and demonstrations , with other Arts and Sciences , as Men ; yet may their perceptions and observations be as wise as Men's , and they may have as much intelligence and commerce betwixt each other , after their own manner and way , as men have after theirs : To which I leave them , and Man to his conceited prerogative and excellence , resting ,

COncerning Sense and Perception , your Authors opinion is , That it is made by a motion or impression from the object upon the sensitive organ , Philos. part. 4. a. 189. which impression , by means of the nerves , is brought to the brain , and so to the mind or soul , which onely perceives in the brain ; Explaining it by the example of a Man being blind , or walking in dark , who by the help Diopt. c. 1. a. 2 , 3. &c. 4. a. 1. of his stick can perceive when he touches a Stone , a Tree , Water , Sand , and the like ; which example he brings to make a comparison with the perception of Light ; For , says he , Light in a shining body , is nothing else but a quick and lively motion or action , which through the air and other transparent bodies tends towards the eye , in the same manner as the motion or resistance of the bodies , the blind man meets withal , tends thorow the stick towards the hand ; wherefore it is no wonder that the Sun can display its rays so far in an instant , seeing that the same action , whereby one end of the stick is moved , goes instantly also to the other end , and would do the same if the stick were as long as Heaven is distant from Earth . To which I answer first , That it is not onely the Mind that perceives in the kernel of the Brain , but that there is a double perception , rational and sensitive , and that the mind perceives by the rational , but the body and the sensitive organs by the sensitive perception ; and as there is a double perception , so there is also a double knowledg , rational tional and sensitive , one belonging to the mind , the other to the body ; for I believe that the Eye , Ear , Nose , Tongue , and all the Body , have knowledg as well as the Mind , onely the rational matter , being subtil and pure , is not incumbred with the grosser part of matter , to work upon , or with it , but leaves that to the sensitive , and works or moves onely in its own substance , which makes a difference between thoughts , and exterior senses . Next I say , That it is not the Motion or Reaction of the bodies , the blind man meets withal , which makes the sensitive perception of these objects , but the sensitive corporeal motions in the hand do pattern out the figure of the Stick , Stone , Tree , Sand , and the like . And as for comparing the perception of the hand , when by the help of the stick it perceives the objects , with the perception of light , I confess that the sensitive perceptions do all resemble each other , because all sensitive parts of matter are of one degree , as being sensible parts , onely there is a difference according to the figures of the objects presented to the senses ; and there is no better proof for perception being made by the sensitive motions in the body , or sensitive organs , but that all these sensitive perceptions are alike ; and resemble one another ; for if they were not made in the body of the sentient , but by the impression of exterior objects , there would be so much difference betwixt them , by reason of the diversity of objects , as they would have no resemblance at all . But for a further proof of my own opinion , did the perception proceed meerly from the motion , impression and resistance of the objects , the hand could not perceive those objects , unless they touched the hand it self , as the stick doth ; for it is not probable , that the motions of the stone , water , sand ; &c. should leave their bodies and enter into the stick , and so into the hand ; for motion must be either something or nothing ; if something , the stick and the hand would grow bigger , and the objects touched less , or else the touching and the touched must exchange their motions , which cannot be done so suddenly , especially between solid bodies ; But if motion has no body , it is nothing , and how nothing can pass or enter or move some body , I cannot conceive . T is true there is no part that can subsist singly by it self , without dependance upon each other , and so parts do always joyn and touch each other , which I am not against ; but onely I say perception is not made by the exterior motions of exterior parts of objects , but by the interior motions of the parts of the body sentient . But I have discoursed hereof before , and so I take my leave , resting ,

ICannot conceive why your Author is so much for little and insensible parts , out of which the Elements and all other bodies are made ; for though Nature is divideable , yet she is also composeable ; and I think there is no need to dissect every creature into such little parts , to know their nature , but we can do it by another way as well ; for we may dissect or divide them into never so little parts , and yet gain never the more knowledg by it . But according to these principles he describing amongst the rest the nature of Water , says , That those little Of Meteor . 1. a. 3. parts , out of which Water consists , are in figure somewhat long , light and slippery like little Eeles , which are never so closely joyned and entangled , but may easily be separated . To which I answer , That I observe the nature and figure of water to be flowing , dilating , divideable and circular ; for we may see , in Tides , overflowings , and breaking into parts , as in rain , it will always move in a round and circular figure ; And I think , if its parts were long and entangled like a knot of Eeles , it could never be so easily contracted and denced into snow or ice . Neither do I think , That Salt-water hath a mixture of somewhat grosser parts , not so apt to bend ; for to C. 3. a. 1. my observation and reason , the nature of salt-water consists herein , that its circle-lines are pointed , which sharp and pointed figure makes it so penetrating ; yet may those points be separated from the circle lines of water , as it is seen in the making of Salt . But I am not of your Authors opinion , That those little points do stick so fast in flesh , as little nails , to keep it from putrefaction ; for points do not always fasten ; or else fire , which certainly is composed of sharp-pointed parts , would harden , and keep other bodies from dissolving , whereas on the contrary , it separates and divides them , although after several manners . But Putrefaction is onely a dissolving and separating of parts , after the manner of dilation ; and the motion of salt is contracting as well as penetrating , for we may observe , what flesh soever is dry-salted , doth shrink and contract close together ; I will not say , but the pointed parts of salt may fasten like nayls in some sorts of bodies , but not in all they work on . And this is the reason also , that Sea-water is of more weight then fresh-water , for being composed of points , those points stick within each other , and so become more strong ; But yet do they not hinder the circular dilating motion of water , for the circle-lines are within , and the points without , but onely they make it more strong from being divided by other exterior bodies that swim upon it . And this is the cause that Salt-water is not so easily forced or turned to vapour , as Fresh , for the points piercing into each other , hold it more strongly together ; but this is to be considered , that the points of salt are on the outside of the watry Circle , not on the inside , which causes it to be divideable from the watry Circles . I will conclude , when I have given the reason why water is so soon suckt up by sand , lime , and the like bodies , and say that it is the nature of all spongy , dry and porous bodies , meeting with liquid and pliable bodies as water , do draw and suck them up , like as animal Creatures being thirsty , do drink : And so I take my leave , and rest ,

COncerning Vapour , Clouds , Wind and Rain , I am of your Authors opinion , That Water is changed into Vapour , and Vapour into Air , and that dilated Vapours make Wind , and condensed Vapours , Clouds Of Meteor . c. 2 , 4 , 5 , 6. and Mists ; But I am not for his little particles , whereof , he says , Vapours are made , by the motion of a rare and subtil matter in the pores of terrestrial bodies ; which certainly I should conceive to be loose atoms , did he not make them of several figures and magnitude : for , in my opinion , there are no such things in nature , which like little Flyes or Bees do fly up into the air ; and although I grant , that in Nature are several parts , whereof some are more rare , others more dense , according to the several degrees of matter , yet they are not single , but all mixt together in one body , and the change of motions in those joyned parts , is the cause of all changes of figures whatever , without the assistance of any forreign parts : And thus Water of it self is changed to Snow , Ice , or Hail , by its inherent figurative Motions ; that is , the circular dilation of Water by contraction , changes into the figure of Snow , Ice , or Hail ; or by rarifying motions it turns into the figure of Vapour , and this Vapour again by contracting motions into the figure of hoar-frost ; and when all these motions change again into the former , then the figure of Ice , Snow , Hail , Vapour and Frost , turns again into the figure of Water : And this in all sense and reason is the most facil and probable way of making Ice , Snow , Hail , &c. As for rarefaction and condensation , I will not say that they may be forced by forreign parts , but yet they are made by change and alteration of the inherent motions of their own parts , for though the motions of forreign parts , may be the occasion of them , yet they are not the immediate cause or actors thereof . And as for Thunder , that clouds of Ice and Snow , the uppermost being condensed by heat , and so made heavy , should fall upon another and produce the noise of thunder , is very improbable ; for the breaking of a little small string , will make a greater noise then a huge shower of snow with falling , and as for Ice being hard , it may make a great noise , one part falling upon another , but then their weight would be as much as their noise , so that the clouds or roves of Ice would be as soon upon our heads , if not sooner , as the noise in our Eares ; like as a bullet shot out of a Canon , we may feel the bullet as soon as we hear the noise . But to conclude , all densations are not made by heat , nor all noises by pressures , for sound is oftener made by division then pressure , and densation by cold then by heat : And this is all for the present , from ,

I Cannot perceive the Rational Truth of your Authors opinion , concerning Colours , made by the agitation of little spherical bodies of an AEthereal matter , transmitting the action of Light ; for if colours were made after this manner , there would , in my opinion , not be any fixed or lasting colour , but one colour would be so various , and change faster then every minute ; the truth is , there would be no certain or perfect colour at all : wherefore it seems altogether improbable , that such liquid , rare and disunited bodies should either keep or make inherent and fixed colours ; for liquid and rare bodies , whose several parts are united into one considerable bulk of body , their colours are more apt to change then the colours of those bodies that are dry , solid and dense ; the reason is , that rare and liquid bodies are more loose , slack , and agil , then solid and dry bodies , in so much , as in every alteration of motion their colours are apt to change : And if united rare and liquid bodies be so apt to alter and change , how is it probable , that those bodies , which are small and not united , should either keep or make inherent fixed colours ? I will not say , but that such little bodies may range into such lines and figures , as make colours , but then they cannot last , being not united into a lasting body , that is , into a solid , substantial body , proper to make such figures as colours . But I desire you not to mistake me , Madam , for I do not mean , that the substance of colours is a gross thick substance , for the substance may be as thin and rare as flame or light , or in the next degree to it ; for certainly the substance of light , and the substance of colours come in their degrees very neer each other ; But according to the contraction of the figures , colours are paler or deeper , or more or less lasting . And as for the reason , why colours will change and rechange , it is according as the figures alter or recover their forms ; for colours will be as animal Creatures , which sometimes are faint , pale , and sick , and yet recover ; but when as a particular colour is , as I may say , quite dead , then there is no recovering of it . But colours may seem altered sometimes in our eyes , and yet not be altered in themselves ; for our eyes , if perfect , see things as they are presented ; and for proof , if any animal should be presented in an unusual posture or shape , we could not judg of it ; also if a Picture , which must be viewed side-wards , should be looked upon forwards , we could not know what to make of it ; so the figures of colours , if they be not placed rightly to the sight , but turned topsie-turvie as the Phrase is , or upside-down , or be moved too quick , and this quick motion do make a confusion with the lines of Light , we cannot possibly see the colour perfectly . Also several lights or shades may make colours appear otherwise then in themselves they are , for some sorts of lights and shades may fall upon the substantial figures of colours in solid bodies , in such lines and figures , as they may over-power the natural or artificial inherent colours in solid bodies , and for a time make other colours , and many times the lines of light or of shadows will meet and sympathize so with inherent colours , and place their lines so exactly , as they will make those inherent colours more splendorous then in their own nature they are , so that light and shadows will add or diminish or alter colours very much . Likewise some sorts of colours will be altered to our sight , not by all , but onely by some sorts of light , as for example , blew will seem green , and green blew by candle light , when as other colours will never appear changed , but shew constantly as they are ; the reason is , because the lines of candle light fall in such figures upon the inherent colours , and so make them appear according to their own figures ; Wherefore it is onely the alteration of the exterior figures of light and shadows , that make colours appear otherwise , and not a change of their own natures ; And hence we may rationally conclude , that several lights and shadows by their spreading and dilating lines may alter the face or out-side of colours , but not suddenly change them , unless the power of heat , and continuance of time , or any other cause , do help and assist them in that work of metamorphosing or transforming of colours ; but if the lines of light be onely , as the phrase is , Skin-deep ; that is , but lightly spreading and not deeply penetrating , they may soon wear out or be rubbed of ; for though they hurt , yet they do not kill the natural colour , but the colour may recover and reassume its former vigour and lustre : but time and other accidental causes will not onely alter , but destroy particular colours as well as other creatures , although not all after the same manner , for some will last longer then others . And thus , Madam , there are three sorts of Colours , Natural , Artificial , and Accidental ; but I have discoursed of this subject more at large in my Philosophical Opinions , to which I refer you , and rest ,

MY answer to your Authors question , Why flame ascends in a pointed figure ? is , That the figure P. 4. art. 97. of fire consists in points , and being dilated into a flame , it ascends in lines of points slope-wayes from the fired fuel ; like as if you should make two or more sticks stand upright and put the upper ends close together , but let the lower ends be asunder , in which posture they will support each other , which , if both their ends were close together , they could not do . The second question is , Why fire doth not alwayes flame ? Art. 107. I answer , Because all fuel is not flameable , some being so moist , as it doth oppose the fires dryness , and some so hard and retentive , as fire cannot so soon dissolve it ; and in this contest , where one dissipares , and the other retains , a third figure is produced , viz. smoak , between the heat of one , and the moisture of the other ; and this smoak is forced by the fire out of the fuel , and is nothing else but certain parts of fuel , raised to such a degree of rarefaction ; and if fire come near , it forces the smoak into flame , the smoak changing it self by its figurative motions into flame ; but when smoak is above the flame , the flame cannot force the smoak to fire or enkindle it self , for the flame cannot so well encounter it ; which shews , as if smoak had a swifter motion then flame , although flame is more rarified then smoak ; and if moisture predominate , there is onely smoak , if fire , then there is flame : But there are many figures , that do not flame , until they are quite dissolved , as Leather , and many other things . Neither can fire work upon all bodies alike , but according to their several natures , like as men cannot encounter several sorts of creatures after one and the same manner ; for not any part in nature hath an absolute power , although it hath self-motion ; and this is the reason , that wax by fire is melted , and clay hardened . The third question is , Why some few drops of water sprinkled upon fire , do encrease its flame ? I answer , by reason of their little quantity , which being over-powred by the greater quantity and force of fire , is by its self-motions converted into fire ; for water being of a rare nature , and fire , for the most part , of a rarifying quality , it cannot suddenly convert it self into a more solid body then its nature is , but following its nature by force it turns into flame . The fourth question is , Why the flame of spirit of Wine doth consume the Wine , and yet cannot burn or hurt a linnen cloth ? I answer , The Wine is the fuel that feeds the flame , and upon what it feeds , it devoureth , and with the food , and feeder ; but by reason Wine is a rarer body then Oyle , or Wood , or any other fuel , its flame is also weaker . And thus much of these questions , I rest ,

TO conclude my discourse upon the Opinions of these two famous and learned Authors , which I have hitherto sent you in several Letters , I could not chuse but repeat the ground of my own opinions in this present ; which I desire you to observe well , left you mistake any thing , whereof I have formerly discoursed . First I am for self-moving matter , which I call the sensitive and rational matter , and the perceptive and architectonical part of nature , which is the life and knowledg of nature . Next I am of an opinion , That all Perception is made by corporeal , figuring self-motions , and that the perception of forreign objects is made by patterning them out : as for example , The sensitive perception of forreign objects is by making or taking copies from these objects , so as the sensitive corporeal motions in the eyes copy out the objects of sight , and the sensitive corporeal motions in the ears copy out the objects of sound ; the sensitive corporeal motions in the nostrils ; copy out the objects of sent ; the sensitive corporeal motions in the tongue and mouth , copy out the objects of taste , and the sensitive corporeal motions in the flesh and skin of the body copy out the forreign objects of touch ; for when you stand by the fire , it is not that the fire , or the heat of the fire enters your flesh , but that the sensitive motions copy out the objects of fire and heat . As for my Book of Philosophy , I must tell you , that it treats more of the production and architecture of Creatures then of their perceptions , and more of the causes then the effects , more in a general then peculiar way , which I thought necessary to inform you of , and so I remain ,

I Received your questions in your last : the first was , Whether there be more body compact together in a heavy then in a light thing ? I answer , That purity , rarity , little quantity , exteriour shape , as also motion cause lightnesse ; and grossness of bulk , density , much quantity , exterior figure and motion cause heaviness , as it may be confirmed by many examples : but lightness and heaviness are onely conceptions of man , as also ascent and descent ; and it may be questioned , whether there be such things really in nature ; for change of motions of one and the same body will make lightness , and heaviness , as also rarity and density : besides , the several figures and compositions of bodies will cause them to ascend or descend , for Snow is a light body and yet descends fron the clouds , and Water is a heavie body , and yet ascends in springs out of the Earth ; Dust is a dense body and yet is apt to ascend , Rain or Dew is a rare body and yet is apt to descend ; Also a Bird ascends by his shape , and a small worm although of less body and lighter will fall down ; and there can be no other prof of light and heavy bodies but by their ascent and descent ; But as really there is no such thing as heavie or light in nature more then words , and comparisons of different corporeal motions , so there is no such thing , as high or low , place or time , but onely words to make comparisons and to distinguish different corporeal motions . The second question was , When a Bason with water is wasted into smoak , which fills up a whole Room , Whether the air in the room doth , as the sensitive motions of the eye , pattern out the figure of the smoak ; or whether all the room is really fill'd with the vapour or smoak ? I answer , If it be onely the pattern or figure of smoak or vapour , the extension and dilation is not so much as man imagines ; but why may not the air , which in my opinion hath self-motion , pattern out the figure of smoak as well as the eye ? for that the eye surely doth it , may be proved ; because smoak , if it enter the eye , makes it not onely smart and water much , but blinds it quite for the present ; wherefore smoak doth not enter the eye , when the eye seeth it , but the eye patterns out the figure of smoak , and this is perception ; In the same manner may the air pattern out the figure of smoak . The third question was ; Whether all that they name qualities of bodies , as thickness , thinness , hardness , softness , gravity , levity , transparentness and the like , be substances ? I answer , That all those , they call qualities , are nothing else but change of motion and figure of the same body , and several changes of motions are not several bodies , but several actions of one body ; for change of motion doth not create new matter or multiply its quantity : for though corporeal motions may divide and compose , contract and dilate , yet they cannot create new matter , or make matter any otherwise then it is by nature , neither can they add or substract any thing from its nature . And therefore my opinion is , not that they are things subsisting by themselves without matter , but that there can no abstraction be made of motion and figure from matter , and that matter and motion being but one thing and inseparable , make but one substance . Wherefore density and rarity , gravity and levity , &c. being nothing else but change of motions , cannot be without matter , but a dense or rare , heavie or light matter is but one substance or body ; And thus having obeyed your commands , I rest ,

XLIV . MADAM ,

IAm very ready to give you my opinion of those two questions you sent me , whereof the first was , Whether that , which is rare and subtil , be not withal pure ? To which I answer , That all rare bodies are not subtil , nor pure , and that all which is dense is not gross and dull : As for example , Puddle-water , or also clear water , is rarer then Quicksilver , and yet not so subtil and pure as Quicksilver ; the like of Gold ; for Quicksilver and Gold may be rarified to a transparentness , and yet be so dense , as not to be easily dissolved ; and Quicksilver is very subtil and searching , so as to be able to force other bodies to divide as well as it can divide and compose its own parts . Wherefore my opinion is , that the purest and subtilest degree of matter in nature , is that degree of matter which can dilate and contract , compose and divide into any figure by corporeal self-motion . Your second question was , Why a man's hand cannot break a little hard body , as a little nail , whereas yet it is bigger then the nail ? I answer , It is not because the hand is softer then the nail , for one hard body will not break suddenly another hard body , and a man may easily break an iron nail with his hand , as I have bin informed ; but it is some kind of motion which can easier do it , then another : for I have seen a strong cord wound about both a man's hands , who pulled his hands as hard and strongly asunder as he could , and yet was not able to break it ; when as a Youth taking the same cord , and winding it about his hands as the former did , immediately broke it ; the cause was , that he did it with another kind of motion or pulling , then the other did , which though he used as much force and strength , as he was able , yet could not break it , when the boy did break it with the greatest ease , and turning onely his hands a little , which shews , that many things may be done by a slight of motion , which otherwise a great strength and force cannot do . This is my answer and opinion concerning your proposed questions ; if you have any more , I shall be ready to obey you , as ,

XLV . MADAM ,

I understand by your last , that you are very desirous to know , Whether there be not in nature such animal creatures both for purity and size , as we are not capable to perceive by our sight . Truly , Madam , in my opinion it is very probable there may be animal creatures of such rare bodies as are not subject to our exterior senses , as well , as there are elements which are not subject to all our exterior senses : as for example , fire is onely subject to our sight and feeling , and not to any other sense , water is subject to our sight , taste , touch and hearing , but not to smelling ; and earth is subject to our sight , taste , touch and smelling , but not to our hearing ; and vapour is onely subject to our sight , and wind onely to our hearing ; but pure air is not subject to any of our senses , but onely known by its effects : and so there may likewise be animal creatures which are not subject to any of our senses both for their purity and life ; as for example , I have seen pumpt out of a water pump small worms which could hardly be discerned but by a bright Sun-light , for they were smaller then the smallest hair , some of a pure scarlet colour and some white , but though they were the smallest creatures that ever I did see , yet they were more agil and fuller of life , then many a creature of a bigger size , and so small they were , as I am confident , they were neither subject to tast , smell , touch nor hearing , but onely to sight , and that neither without dificulty , requiring both a sharp sight and a clear light to perceive them ; and I do verily believe that these small animal creatures may be great in comparison to others which may be in nature . But if it be probable that there may be such small animal creatures in nature , as are not subject to our exterior senses , by reason of their littleness ; it is also probable , that there may be such great and big animal creatures in nature as are beyond the reach and knowledg of our exterior senses ; for bigness and smallness are not to be judged by our exterior senses , onely ; but as sense and reason inform us , that there are different degrees in Purity and Rarity , so also in shapes , figures and sizes in all natural creatures . Next you desired to know , VVhether there can be an artificial Life , or a Life made by Art ? My answer is , Not ; for although there is Life in all natures parts , yet not all the parts are life , for there is one part of natural matter which in its nature is inanimate or without life , and though natural Life doth produce Art , yet Art cannot produce natural Life , for though Art is the action of Life , yet it is not Life it self : not but that there is Life in Art , but not art in life , for Life is natural , and not artificial ; and thus the several parts of a watch may have sense and reason according to the nature of their natural figure , which is steel , but not as they have an artificial shape , for Art cannot put Life into the watch , Life being onely natural , not artificial . Lastly your desire was to know , Whether a part of matter may be so small , as it cannot be made less ? I answer , there is no such thing in nature as biggest or least , nature being Infinite as well in her actions as in her substance ; and I have mentioned in my book of Philosophy , and in a letter , I sent you heretofore concerning Infinite , that there are several forts of Infinites , as Infinite in quantity or bulk , Infinite in number , Infinite in quality , as Infinite degrees of hardness , softness , thickness , thinness , swiftness , slowness , &c. as also Infinite compositions , divisions , creations , dissolutions , &c. in nature ; and my meaning is , that all these Infinite actions do belong to the Infinite body of nature , which being infinite in substance must also of necessity be infinite in its actions ; but although these Infinite actions are inherent in the power of the Infinite substance of nature , yet they are never put in act in her parts , by reason there being contraries in nature , and every one of the aforementioned actions having its opposite , they do hinder and obstruct each other so , that none can actually run into infinite ; for the Infinite degrees of compositions hinder the infinite degrees of divisions ; and the infinite degrees of rarity , softness , swiftness , &c. hinder the infinite degrees of density , hardness , slowness , &c. all which nature has ordered with great wisdom and Prudence to make an amiable combination between her parts ; for if but one of these actions should run into infinite , it would cause a horrid confusion between natures parts , nay an utter destruction of the whole body of nature , if I may call it whole : as for example , if one part should have infinite compositions , without the hinderance or obstruction of division , it would at last mount and become equal to the Infinite body of nature , and so from a part change to a whole , from being finite to infinite , which is impossible ; Wherefore , though nature hath an Infinite natural power , yet she doth not put this power in act in her particulars ; and although she has an infinite force or strength , yet she doth not use this force or strength in her parts . Moreover when I speak of Infinite divisions and compositions , creations and dissolutions , &c. in nature , I do not mean so much the infinite degrees of compositions and divisions , as the actions themselves to be infinite in number ; for there being infinite parts in nature , and every one having its compositions and divisions , creations and dissolutions , these actions must of necessity be infinite too , to wit , in number , according to the Infinite number of parts , for as there is an Infinite number of parts in nature , so there is also an infinite number and variety of motions which are natural actions . However let there be also infinite degrees of these natural actions , in the body or substance of infinite nature ; yet , as I said , they are never put in act , by reason every action hath its contrary or opposite , which doth hinder and obstruct it from running actually into infinite . And thus I hope , you conceive cleerly now , what my opinion is , and that I do not contradict my self in my works , as some have falsly accused me , for they by misapprehending my meaning , judge not according to the truth of my sense , but according to their own false interpretation , which shews not onely a weakness in their understandings and passions , but a great injustice and injury to me , which I desire you to vindicate when ever you chance to hear such accusations and blemishes laid upon my works , by which you will Infinitely oblige ,

SECT. II.
I. MADAM ,

BEing come now to the Perusal of the Works of that learned Author Dr. Moor , I find that the onely design of his Book called Antidote , is to prove the Existence of a God , and to refute , or rather convert Atheists ; which I wonder very much at , considering , he says himself , * * Antidote , Book 1. c. 10. a. 5. That there is no man under the cope of Heaven but believes a God ; which if so , what needs there to make so many arguments to no purpose ? unless it be to shew Learning and wit ; In my opinion , it were better to convert Pagans to be Christians , or to reform irregular Christians to a more pious life , then to prove that , which all men believe , which is the way to bring it into question . For certainly , according to the natural Light of Reason , there is a God , and no man , I believe , doth doubt it ; for though there may be many vain words , yet I think there is no such atheistical belief amongst man-kind , nay , not onely amongst men , but also , amongst all other creatures , for if nature believes a God , all her parts , especially the sensitive and rational , which are the living and knowing parts , and are in all natural creatures , do the like , and therefore all parts and creatures in nature do adore and worship God , for any thing man can know to the contrary ; for no question , but natures soule adores and worships God as well as man's soule ; and why may not God be worshipped by all sorts and kinds of creatures as well , as by one kind or sort ? I will not say the same way , but I believe there is a general worship and adoration of God ; for as God is an Infinite Deity , so certainly he has an Infinite Worship and Adoration , and there is not any part of nature , but adores and worships the only omnipotent God , to whom belongs Praise and Glory from and to all eternity : For it is very improbable , that God should be worshipped onely in part , and not in whole , and that all creatures were made to obey man , and not to worship God , onely for man's sake , and not for God's worship , for man's use , and not God's adoration , for mans spoil and not God's blessing . But this Presumption , Pride , Vain-glory and Ambition of man , proceeds from the irregularity of nature , who being a servant , is apt to commit errors ; and cannot be so absolute and exact in her devotion , adoration and worship , as she ought , nor so well observant of God as God is observing her : Nevertheless , there is not any of her parts or creatures , that God is not acknowledged by , though not so perfectly as he ought , which is caused by the irregularities of nature , as I said before . And so God of his mercy have mercy upon all Creatures ; To whose protection I commend your Ladiship , and rest ,

MADAM , Your faithful Friend and Servant .
II. MADAM ,

SInce I spake in my last of the adoration and worship of God , you would faine know , whether we can have an Idea of God ? I answer , That naturally we may , and really have a knowledge of the existence of God , as I proved in my former letter , to wit , that there is a God , and that he is the Author of all things , who rules and governs all things , and is also the God of Nature : but I dare not think , that naturally we can have an Idea of the essence of God , so as to know what God is in his very nature and essence ; for how can there be a finite Idea of an Infinite God ? You may say , As well as of Infinite space . I answer , Space is relative , or has respect to body , but there is not any thing that can be compared to God ; for the Idea of Infinite nature is material , as being a material creature of Infinite material Nature . You will say , How can a finite part have an Idea of infinite nature ? I answer , Very well , by reason the Idea is part of Infinite Nature , and so of the same kind , as material ; but God being an Eternal , Infinite , Immaterial , Individable Being , no natural creature can have an Idea of him . You will say , That the Idea of God in the mind is immaterial ; I answer , I cannot conceive , that there can be any immaterial Idea in nature ; but be it granted , yet that Immaterial is not a part of God , for God is individable , and hath no parts ; wherefore the Mind cannot have an Idea of God , as it hath of Infinite nature , being a part of nature ; for the Idea of God cannot be of the essence of God , as the Idea of nature is a corporeal part of nature : and though nature may be known in some parts , yet God being Incomprehensible , his Essence can by no wayes or means be naturally known ; and this is constantly believed , by

MADAM , Your faithful Friend , and Servant .
III. MADAM ,

ALthough I mentioned in my last , that it is impossible to have an Idea of God , yet your Author is pleased to say , That he will not stick to affirm , that the Idea or notion of God is as easie , as any notion else Of the Immortality of the Soul , l. 1. a. 4. whatsoever , and that we may know as much of him as of any thing else in the world . To which I answer , That in my opinion , God is not so easily to be known by any creature , as man may know himself ; nor his attributes so well , as man can know his own natural proprieties : for Gods Infinite attributes are not conceivable , and cannot be comprehended by a finite knowledg and understanding , as a finite part of nature ; for though nature's parts may be Infinite in number , and as they have a relation to the Infinite whole , if I may call it so , which is Infinite nature , yet no part is infinite in it self , and therefore it cannot know so much as whole nature : and God being an Infinite Deity , there is required an Infinite capacity to conceive him ; nay , Nature her self although Infinite , yet cannot posibly have an exact notion of God , by reason of the disparity between God and her self ; and therefore it is not probable , if the Infinite servant of God is not able to conceive him , that a finite part or creature of nature , of what kind or sort soever , whether Spiritual , as your Author is pleased to name it , or Corporeal , should comprehend God . Concerning my belief of God , I submit wholly to the Church , and believe as I have bin informed out of the Athanasian Creed , that the Father is Incomprehensible , the Sonne Incomprehensible , and the Holy Ghost Incomprehensible ; and that there are not three , but one Incomprehensible God ; Wherefore if any man can prove ( as I do verily believe he cannot ) that God is not Incomprehensible , he must of necessity be more knowing then the whole Church , however he must needs dissent from the Church . But perchance your Author may say , I raise new and prejudicial opinions , in saying that matter is eternal . I answer , The Holy Writ doth not mention Matter to be created , but onely Particular Creatures , as this Visible World , with all its Parts , as the history or description of the Creation of the World in Genesis plainly shews ; For God said , Let it it be Light , and there was Light ; Let there be a Firmament in the midst of the Waters , and let it divide the Waters from the Waters ; and Let the Waters under the Heaven be gathered together unto one place , and let the dry Land appear ; and let the Earth bring forth Grass , the Herb yielding Seed , and the Fruit-tree yielding Fruit after his kind ; and let there be Lights in the Firmament of the Heaven , to divide the Day from the Night , &c. Which proves , that all creatures and figures were made and produced out of that rude and desolate heap or chaos which the Scripture mentions , which is nothing else but matter , by the powerful Word and Command of God , executed by his Eternal Servant , Nature ; as I have heretofore declared it in a Letter I sent you in the beginning concerning Infinite Nature . But least I seem to encroach too much upon Divinity , I submit this Interpretation to the Church ; However , I think it not against the ground of our Faith ; for I am so far from maintaining any thing either against Church or State , as I am submitting to both in all duty , and shall do so as long as I live , and rest ,

IV. MADAM ,

SInce your Worthy and Learned Author is pleased to mention , That an ample experience both of Men Antid. Book . 2. Ch. 2. a. 1. and Things doth enlarge our Understanding , I have taken occasion hence to enquire , how a mans Understanding may be encreased or inlarged . The Understanding must either be in Parts , or it must be Individable as one ; if in Parts , then there must be so many Understandings as there are things understood ; but if Individable , and but one Understanding , then it must dilate it self upon so many several objects . I for my part , assent to the first , That Understanding increases by Parts , and not by Dilation , which Dilation must needs follow , if the Mind or Understanding of man be Indivisible and without parts ; but if the Mind or Soul be Individable , then I would fain know , how Understanding , Imagination , Conception , Memory , Remembrance , and the like , can be in the mind ? You will say , perhaps , they are so many faculties or properties of the Incorporeal Mind , but , I hope , you do not intend to make the Mind or Soul a Deity , with so many attributes , Wherefore , in my opinion , it is safer to say , That the Mind is composed of several active Parts : but of these Parts I have treated in my Philosophy , where you will find , that all the several Parts of Nature are Living and Knowing , and that there is no part that has not Life and Knowledg , being all composed of rational and sensitive matter , which is the life and soul of Nature ; and that Nature being Material , is composable and dividable , which is the cause of so many several Creatures , where every Creature is a part of Nature , and these Infinite parts or creatures are Nature her self ; for though Nature is a self-moving substance , and by self-motion divides and composes her self several manners or ways into several forms and figures , yet being a knowing , as well as a living substance , she knows how to order her parts and actions wisely ; for as she hath an Infinite body or substance , so she has an Infinite life and knowledg ; and as she hath an Infinite life and knowledg , so she hath an infinite wisdom : But mistake me not , Madam ; I do not mean an Infinite Divine Wisdom , but an Infinite Natural Wisdom , given her by the Infinite bounty of the Omnipotent God ; but yet this Infinite Wisdom , Life and Knowledg in Nature make but one Infinite . And as Nature hath degrees of matter , so she has also degrees and variety of corporeal motions ; for some parts of matter are self-moving , and some are moved by these self-moving parts of matter ; and all these parts , both the moving and moved , are so intermixed , that none is without the other , no not in any the least Creature or part of Nature we can conceive ; for there is no Creature or part of Nature , but has a comixture of those mentioned parts of animate and inanimate matter , and all the motions are so ordered by Natures wisdom , as not any thing in Nature can be otherwise , unless by a Supernatural Command and Power of God ; for no part of corporeal matter and motion can either perish , or but rest ; one part may cause another part to alter its motions , but not to quit motion , no more then one part of matter can annihilate or destroy another ; and therefore matter is not meerly Passive , but always Active , by reason of the thorow mixture of animate and inanimate matter ; for although the animate matter is onely active in its nature , and the inanimate passive , yet because they are so closely united and mixed together that they make but one body , the parts of the animate or self-moving matter do bear up and cause the inanimate parts to move and work with them ; and thus there is an activity in all parts of matter moving and working as one body , without any fixation or rest , for all is moveable , moving and moved . All which , Madam , if it were well observed , there would not be so many strange opinions concerning nature and her actions , making the purest and subtillest part of matter immaterial or incorporeal , which is as much , as to extend her beyond nature , and to rack her quite to nothing . But I fear the opinion of Immaterial substances in Nature will at last bring in again the Heathen Religion , and make us believe a god Pan , Bacchus , Ceres , Venus , and the like , so as we may become worshippers of Groves and shadows , Beans and Onions , as our Forefathers . I say not this , as if I would ascribe any worship to Nature , or make her a Deity , for she is onely a servant to God , and so are all her parts or creatures , which parts or creatures , although they are transformed , yet cannot be annihilated , except Nature her self be annihilated , which may be , whensoever the Great God pleases ; for her existence and resolution , or total destruction , depends upon Gods Will and Decree , whom she fears , adores , admires , praises and prayes unto , as being her God and Master ; and as she adores God , so do all her parts and creatures , and amongst the rest Man , so that there is no Atheist in Infinite Nature , at least not in the opinion of ,

V. MADAM ,

I Cannot well conceive what your Author means by the Common Laws of Nature ; But if you desire Antid. Book . 2. c. 2. my opinion how many Laws Nature hath , and what they are ; I say Nature hath but One Law , which is a wise Law , viz. to keep Infinite matter in order , and to keep [ so much Peace , as not to disturb the Foundation of her Government : for though Natures actions are various , and so many times opposite , which would seem to make wars between several Parts , yet those active Parts , being united into one Infinite body , cannot break Natures general Peace ; for that which Man names War , Sickness , Sleep , Death , and the like , are but various particular actions of the onely matter ; not , as your Author imagines , in a confusion , like Bullets , or such like things juggled together in a mans Hat , but very orderly and methodical : And the Playing motions of nature are the actions of Art , but her serious actions are the actions of Production , Generation and Transformation in several kinds , sorts and particulars of her Creatures , as also the action of ruling and governing these her several active Parts . Concerning the Preeminence and Prerogative of Man , whom your Author calls * * C. 3. The flower and chief of all the products of nature upon this Globe of the earth ; I answer , That Man cannot well be judged of himself , because he is a Party , and so may be Partial ; But if we observe well , we shall find that the Elemental Creatures are as excellent as Man , and as able to be a friend or foe to Man , as Man to them , and so the rest of all Creatures ; so that I cannot perceive more abilities in Man then in the rest of natural Creatures ; for though he can build a stately House , yet he cannot make a Honey-comb ; and though he can plant a Slip , yet he cannot make a Tree ; though he can make a Sword , or Knife , yet he cannot make the Mettal . And as Man makes use of other Creatures , so other Creatures make use of Man , as far as he is good for any thing : But Man is not so useful to his neighbour or fellow-creatures , as his neighbour or fellow-creatures to him , being not so profitable for use , as apt to make spoil . And so leaving him , I rest ,

VI. MADAM ,

YOur Author demands , Whether there was ever any man , that was not mortal , and whether there be any mortal that had not a beginning ? Truly , if nature Antid. 1. 3. c. 15. a. 3. be eternal , all the material figures which ever were , are , and can be , must be also eternal in nature ; for the figures cannot be annihilated , unless nature be destroyed ; and although a Creature is dissolved and transformed into numerous different figures , yet all these several figures remain still in those parts of matter , whereof that creature was made , for matter never changes , but is always one and the same , and figure is nothing else but matter transposed or transformed by motion several modes or ways . But if you conceive Matter to be one thing , Figure another , and Motion a third , several , distinct and dividable from each other , it will produce gross errors , for , matter , motion , and figure , are but one thing . And as for that common question , whether the Egg was before the Chick , or the Chick before the Egg , it is but a thred-bare argument , which proves nothing , for there is no such thing as First in Eternity , neither doth Time make productions or generations , but Matter ; and whatsoever matter can produce or generate , was in matter before it was produced ; wherefore the question is , whether Matter , which is Nature , had a beginning , or not ? I say not : for put the case , the figures of Earth , Air , Water , and Fire , Light and Colours , Heat and Cold , Animals , Vegetables and Minerals , &c. were not produced from all Eternity , yet those figures have nevertheless been in Matter , which is Nature , from all eternity , for these mentioned Creatures are onely made by the corporeal motions of Matter , transforming Matter into such several figures ; Neither can there be any perishing or dying in Nature , for that which Man calls so , is onely an alteration of Figure . And as all other productions are but a change of Matters sensitive motions , so all irregular and extravagant opinions are nothing but a change of Matters rational motions ; onely productions by rational motions are interior , and those by sensitive motions exterior . For the Natural Mind is not less material then the body , onely the Matter of the Mind is much purer and subtiller then the Matter of the Body . And thus there is nothing in Nature but what is material ; but he that thinks it absurd to say , the World is composed of meer self-moving Matter , may consider , that it is more absurd to believe Immaterial substances or spirits in Nature , as also a spirit of Nature , which is the Vicarious power of God upon Matter ; For why should it not be as probable , that God did give Matter a self-moving power to her self , as to have made another Creature to govern her ? For Nature is not a Babe , or Child , to need such a Spiritual Nurse , to teach her to go , or to move ; neither is she so young a Lady as to have need of a Governess , for surely she can govern her self ; she needs not a Guardian for fear she should run away with a younger Brother , or one that cannot make her a Jointure . But leaving those strange opinions to the fancies of their Authors , He add no more , but that I am ,

YOur Author being very earnest in arguing against those that maintain the opinion of Matter being self-moving , amongst the rest of his arguments brings in this : Suppose , says he , Matter could Of the Immortality of the Soul , l. 1. c. 12. move it self , would meer Matter with self-motion amount to that admirable wise contrivance of things which we see in the World ? — All the evasion I can imagine , our adversaries may use here , will be this : That Matter is capable of sense , and the finest and most subtil of the most refined sense ; and consequently of Imagination too , yea happily of Reason and Understanding . I answer , it is very probable , that not onely all the Matter in the World or Universe hath Sense , but also Reason ; and that the sensitive part of matter is the builder , and the rational the designer ; whereof I have spoken of before , and you may find more of it in my Book of Philosophy . But , says your Author , Let us see , if all their heads laid together can contrive the anatomical Fabrick of any Creature that liveth ? I answer , all parts of Nature are not bound to have heads or tayls ; but if they have , surely they are wiser then many a man's . I demand , says he , Has every one of these Particles , that must have a hand in the framing of the body of an animal , the whole design of the work by the Impress of some Phantasme upon it ? or as they have several offices , so have they several parts of the design ? I answer , All the actions of self-moving Matter are not Impresses , nor is every part a hand-labourer , but every part unites by degrees into such or such a Figure . Again , says he , How is it conceiveable that any one Particle of Matter , or many together , ( there not existing , yet in Nature an animal ) can have the Idea Impressed of that Creature they are to frame ? I answer , all figures whatsoever have been , are , or can be in Nature , are existent in nature . How , says he , can they in framing several parts confer notes ? by what language or speech can they communicate their Counsels one to another ? I answer , Knowledg doth not always require speech , for speech is an effect and not a cause , but knowledg is a cause and not an effect ; and nature hath infinite more ways to express knowledg then man can imagine , Wherefore , he concludes , that they should mutually serve one another in such a design , is more impossible ; then that so many men , blind and dumb from their nativity , should joyn their forces and wits together to build a Castle , or carve a statue of such a Creature , as none of them knew any more in several , then some one of the smallest parts thereof , but not the relation it bore to the whole . I answer , Nature is neither blind nor dumb , nor any ways defective , but infinitely wife and knowing ; for blindness and dumbness are but effects of some of her particular actions , but there is no defect in self-moving matter , nor in her actions in general ; and it is absurd to conceive the Generality of wisdom according to an Irregular effect or defect of a particular Creature ; for the General actions of Nature are both life and knowledg , which are the architects of all Creatures , and know better how to frame all kinds and sorts of Creatures then man can conceive ; and the several parts of Matter have a more easie way of communication , then Mans head hath with his hand , or his hand with pen , ink , and paper , when he is going to write ; which later example will make you understand my opinion the better , if you do but compare the rational part of Matter to the head , the sensitive to the hand , the inanimate to pen , ink and paper , their action to writing , and their framed figures to those figures or letters which are written ; in all which is a mutual agreement without noise or trouble . But give me leave , Madam , to tell you , That self-moving Matter may sometimes erre and move irregularly , and in some parts not move so strong , curious , or subtil at sometimes , as in other parts , for Nature delights in variety ; Nevertheless she is more wise then any Particular Creature or part can conceive , which is the cause that Man thinks Nature's wise , subtil and lively actions , are as his own gross actions , conceiving them to be constrained and turbulent , not free and easie , as well as wise and knowing ; Whereas Nature's Creating , Generating and Producing actions are by an easie connexion of parts to parts , without Counterbuffs , Joggs and Jolts , producing a particular figure by degrees , and in order and method , as humane sense and reason may well perceive : And why may not the sensitive and rational part of Matter know better how to make a Bee , then a Bee doth how to make Honey and Wax ? or have a better communication betwixt them , then Bees that fly several ways , meeting and joyning to make their Combes in their Hives ? But pardon , Madam , for I think it a Crime to compare the Creating , Generating and producing Coporeal Life and Wisdom of Nature unto any particular Creature , although every particular Creature hath their share , being a part of Nature . Wherefore those , in my opinion , do grosly err , that bind up the sensitive matter onely to taste , touch , hearing , seeing , and smelling ; as if the sensitive parts of Nature had not more variety of actions , then to make five senses ; for we may well observe , in every Creature there is difference of sense and reason according to the several modes of self-motion ; For the Sun , Stars , Earth , Air , Fire , Water , Plants , Animals , Minerals ; although they have all sense and knowledg , yet they have not all sense and knowledg alike , because sense and knowledg moves not alike in every kind or sort of Creatures , nay many times very different in one and the same Creature ; but yet this doth not cause a general Ignorance , as to be altogether Insensible or Irrational , neither do the erroneous and irregular actions of sense and reason prove an annihilation of sense and reason ; as for example , a man may become Mad or a Fool through the irregular motions of sense and reason , and yet have still the Perception of sense and reason , onely the alteration is caused through the alteration of the sensitive and rational corporeal motions or actions , from regular to irregular ; nevertheless he has Perceptions , Thoughts , Ideas , Passions , and whatsoever is made by sensitive and rational Matter , neither can Perception be divided from Motion , nor Motion from Matter ; for all sensation is Corporeal , and so is Perception . I can add no more , but take my leave , and rest ,

YOur Author is pleased to say , that Matter is a Principle purely passive , and no otherwise moved or modified , Of the Immortality of the Soul , l. 2. c. 1. a. 3. then as some other thing moves and modifies it , but cannot move it self at all ; which is most demonstrable to them that contend for sense and perception in it : For if it had any such perception , it would , by vertue of its self-motion withdraw its self from under the knocks of hammers , or fury of the fire ; or of its own accord approach to such things as are most agreeable to it , and pleasing , and that without the help of muscles , it being thus immediately endowed with a self-moving power . By his leave , Madam , I must tell you , that I see no consequence in this argument ; Because some parts of matter cannot withdraw themselves from the force and power of other parts , therefore they have neither sense , reason , nor perception : For put the case , a man should be overpowr'd by some other men , truely he would be forced to suffer , and no Immaterial Spirits , I think , would assist him . The very same may be said of other Creatures or parts of Nature ; for some may over-power others , as the fire , hammer and hand doth over-power a Horse-shooe , which cannot prevail over so much odds of power and strength ; And so likewise it is with sickness and health , life and death ; for example , some corporeal motions in the body turning Rebels , by moving contrary to the health of an animal Creature , it must become sick ; for not every particular creature hath an absolute power , the power being in the Infinite whole , and not in single divided parts : Indeed , to speak properly , there is no such thing as an absolute power in Nature ; for though Nature hath power to move it self , yet not beyond it self . But mistake me not , for I mean by an absolute Power ; not a circumscribed and limited , but an unlimited power , no ways bound or confined , but absolutely or every way Infinite , and there is not any thing that has such an absolute power but God alone : neither can Nature be undividable , being Corporeal or Material ; nor rest from motion being naturally self-moving , and in a perpetual motion . Wherefore though Matter is self-moving , and very wise , ( although your Author denies it , calling those Fools that maintain this a a In the Append . to the Antid. c. 3. a. 10. opinion ) yet it cannot go beyond the rules of its Nature , no more then any Art can go beyond its Rules and Principles : And as for what your Author says , That every thing would approach to that , which is agreeable and pleasant ; I think I need no demonstration to prove it ; sor we may plainly see it in all effects of Nature , that there is Sympathy and Antipathy , and what is this else , but approaching to things agreeable and pleasant , and withdrawing it self from things disagreeable , and hurtful or offensive ? But of this subject I shall discourse more hereafter , wherefore I finish here , and rest ,

YOur Authors opinion is , That Matter being once actually divided as far as possibly it can , it is a perfect In the Preface before the Imm. of the Soul . contradiction it should be divided any further . I answer , Though Nature is Infinite , yet her actions are not all dilative nor separative , but some divide and some compose , some dilate and some contract , which causes a mean betwixt Natures actions or motions . Next your Author says , That as Infinite Greatness has no Figure , so Infinite Littleness hath none also . I answer , Whatsoever hath a body , has a figure ; for it is impossible that substance , or body , and figure , should be separated from each other , but wheresoever is body or substance , there is also figure , and if there be an infinite substance , there must also be an infinite figure , although not a certain determined or circumscribed figure , for such a figure belongs onely to finite particulars ; and therefore I am of your Authors mind , That it is a contradiction to say an Infinite Cube or Triangle , for a Cube and a Triangle is a perfect circumscribed figure , having its certain compass and circumference , be it never so great or little ; wherefore to say an Infinite Cube , would be as much as to say a Finite Infinite . But as for your Authors example of Infinite matter , space or duration , divided into three equal parts , all which he says must needs be Infinite , or else the whole wil not be so , and then the middle part of them will seem both Finite and Infinite . I answer , That Matter is not dividable into three equal parts , for three is a finite number and so are three equal parts ; but I say that Matter being an Infinite body , is dividable into Infinite parts , and it doth not follow , as your Author says , That one of those infinite parts must be infinite also , for else there would be no difference betwixt the whole and its parts ; I say whole for distinctions and better expressions sake , and do not mean such a whole which hath a certain number of parts , and is of a certain and limited figure , although never so great ; but an Infinite whole , which expression I must needs use , by reason I speak of Infinite parts ; and that each one of these Infinite parts in number may be finite in substance or figure , is no contradiction , but very probable and rational ; nay , I think it rather absurd to say that each part is infinite ; for then there would be no difference betwixt parts and whole , as I said before . Onely this is to be observed , that the Infinite whole is Infinite in substance or bulk , but the parts are Infinite in number , and not in bulk , for each part is circumscribed , and finite in its exterior figure and substance . But mistake me not , when I speak of circumscribed and finite single parts ; for I do not mean , that each part doth subsist single and by it self , there being no such thing as an absolute single part in Nature , but Infinite Matter being by self-motion divided into an infinite number of parts , all these parts have so near a relation to each other , and to the infinite whole , that one cannot subsist without the other ; for the Infinite parts in number do make the Infinite whole , and the Infinite whole consists in the Infinite number of parts ; wherefore it is onely their figures which make a difference betwixt them ; for each part having its proper figure different from the other , which is circumscribed and limited , it is called a finite single part ; and such a part cannot be said Infinitely dividable , for infinite composition and division belong onely to the Infinite body of Nature , which being infinite in substance may also be infinitely divided , but not a finite and single part : Besides , Infinite composition doth hinder the Infinite division , and Infinite division hinders the Infinite composition ; so that one part cannot be either infinitely composed , or infinitely divided ; and it is one thing to be dividable , and another to be divided . And thus , when your Author Antid. Book . 2. c. 4. mentions in another place , That if a body be divisible into Infinite Parts , it hath an Infinite number of extended parts : If by extension he mean corporeal dimension , I am of his opinion ; for there is no part , be it never so little in Nature , but is material ; and if material , it has a body ; and if a body , it must needs have a bodily dimension ; and so every part will be an extended part : but since there is no part but is finite in its self , it cannot be divisible into infinite parts ; neither can any part be infinitely dilated or contracted ; for as composition and division do hinder and obstruct each other from running into Infinite , so doth dilation hinder the Infinite contraction , and contraction the Infinite dilation , which , as I said before , causes a mean betwixt Nature's actions ; nevertheless , there are Infinite dilations and contractions in Nature , because there are Infinite contracted and dilated parts , and so are infinite divisions because there are infinite divided parts ; but contraction , dilation , extension , composition , division , and the like , are onely Nature's several actions ; and as there can be no single part in Nature that is Infinite , so there can neither be any single Infinite action . But as for Matter , Motion and Figure , those are Individable and Inseparable , and make but one body or substance ; for it is as impossible to divide them , as impossible it is to your Author to separate the essential proprieties , which he gives , from an Immortal Spirit ; And as Matter , Motion and Figure are inseparable ; so is likewise Matter , Space , Place and Duration ; For Parts , Motion , Figure , Place and Duration , are but one Infinite body ; onely the Infinite parts are the Infinite divisions of the Infinite body , and the Infinite body is a composition of the Infinite parts ; but figure , place and body are all one , and so is time , and duration , except you will call time the division of duration , and duration the composition of time ; but infinite time , and infinite duration is all one in Nature : and thus Nature's Principal motions and actions are dividing , composing , and disposing or ordering , according to her Natural wisdom , by the Omnipotent God's leave and permission . Concerning the Sun , which your Author speaks of in the same place , and denies him to be a Spectator of our Particular affairs upon Earth ; saying , there is no such divine Principle in him , whereby he can do it . I will speak nothing against , nor for it ; but I may say , that the Sun hath such a Principle as other Creatures have , which is , that he has sensitive and rational corporeal motions , as well as animals or other Creatures , although not in the same manner , nor the same organs ; and if he have sensitive and rational motions , he may also have sensitive and rational knowledge or perception , as well as man , or other animals and parts of Nature have , for ought any body knows ; for it is plain to humane sense and reason , that all Creatures must needs have rational and sensitive knowledg , because they have all sensitive and rational matter and motions . But leaving the Sun for Astronomers to contemplate upon , I take my leave , and rest ,

YOur Author in his arguments against Motion , being a Principle of Nature , endeavours to prove , Append. to the Antid. c. 11. that Beauty , Colour , Symmetry , and the like , in Plants , as well as in other Creatures , are no result from the meer motion of the matter ; and forming this objection , It may be said , says he , That the regular motion of the matter made the first plant of every kind ; but we demand , What regulated the motion of it , so as to guide it , to form it self into such a state ? I answer , The Wisdom of Nature or infinite Matter did order its own actions so , as to form those her Parts into such an exact and beautiful figure , as such a Tree , or such a Flower , or such a Fruit , and the like ; and some of her Parts are pleased and delighted with other parts , but some of her parts are afraid or have an aversion to other parts ; and hence is like and dislike , or sympathy and antipathy , hate and love , according as nature , which is infinite self-moving matter , pleases to move ; for though Natural Wisdom is dividable into parts , yet these parts are united in one infinite Body , and make but one Being in it self , like as the several parts of a man make up but one perfect man ; for though a man may be wise in several causes or actions , yet it is but one wisdom ; and though a Judg may shew Justice in several causes , yet it is but one Justice ; for Wisdom and Justice , though they be practised in several causes , yet it is but one Wisdom , and one Justice ; and so , all the parts of a mans body , although they move differently , yet are they but one man's bodily actions ; Just as a man , if he carve or cut out by art several statues , or draw several Pictures , those statues or pictures are but that one man's work . The like may be said of Natures Motions and Figures ; all which are but one self-active or self-moving Material Nature . But Wise Nature's Ground or Fundamental actions are very Regular , as you may observe in the several and distinct kinds , sorts and particulars of her Creatures , and in their distinct Proprieties , Qualities , and Faculties , belonging not onely to each kind and sort , but to each particular Creature ; and since man is not able to know perfectly all those proprieties which belong to animals , much less will he be able to know and judg of those that are in Vegetables , Minerals and Elements ; and yet these Creatures , for any thing Man knows , may be as knowing , understanding , and wise as he ; and each as knowing of its kind or sort , as man is of his ; But the mixture of ignorance and knowledg in all Creatures proceeds from thence , that they are but Parts ; and there is no better proof , that the mind of man is dividable , then that it is not perfectly knowing ; nor no better proof that it is composeable , then that it knows so much : but all minds are not alike , but some are more composed then others , which is the cause , some know more then others ; for if the mind in all men were alike , all men would have the same Imaginations , Fancies , Conceptions , Memories , Remembrances , Passions , Affections , Understanding , and so forth : The same may be said of their bodies ; for if all mens sensitive parts were as one , and not dividable and composeable , all their Faculties , Properties , Constitutions , Complexions , Appetites , would be the same in every man without any difference ; but humane sense and reason doth well perceive , that neither the mind , life nor body are as one piece , without division and composition . Concerning the divine Soul , I do not treat of it ; onely this I may say , That all are not devout alike , nor those which are , are not at all times alike devout . But to conclude : some of our modern Philosophers think they do God good service , when they endeavour to prove Nature , as Gods good Servant , to be stupid , ignorant , foolish and mad , or any thing rather then wise , and yet they believe themselves wise , as if they were no part of Nature ; but I cannot imagine any reason why they should rail on her , except Nature had not given them as great a share or portion , as she hath given to others ; for children in this case do often rail at their Parents , for leaving their Brothers and Sisters more then themselves . However , Nature can do more then any of her Creatures : and if Man can Paint , Imbroider , Carve , Ingrave curiously ; why may not Nature have more Ingenuity , Wit and Wisdom then any of her particular Creatures ? The same may be said of her Government . And so leaving Wise Nature , I rest ,

TO your Authors argument , That if Motion belong naturally to Matter , Matter being Uniform , Antid. l. 2. c. 1. it must be alike moved in every part of particle imaginable of it , by reason this Motion being natural and essential to Matter , is alike every way . I answer , That this is no more necessary , then that the several actions of one body , or of one part of a body should be alike ; for though Matter is one and the same in its Nature , and never changes , yet the motions are various , which motions are the several actions of one and the same Natural Matter ; and this is the cause of so many several Creatures ; for self-moving matter by its self-moving power can act several ways , modes or manners ; and had not natural matter a self-acting power , there could not be any variety in Nature ; for Nature knows of no rest , there being no such thing as rest in Nature ; but she is in a perpetual motion , I mean self-motion , given her from God : Neither do I think it Atheistical ( as your Author deems ) to maintain this opinion of self-motion , as long as I do not deny the Omnipotency of God ; but I should rather think it Irreligious to make so many several Creatures as Immaterial Spirits , like so many severall Deities , to rule and govern Nature and all material substances in Nature ; for what Atheism doth there lie in saying , that natural matter is naturally moving , and wise in her self ? Doth this oppose the omnipotency and Infinite wisdom of God ? It rather proves and confirms it ; for all Natures free power of moving and wisdom is a gift of God , and proceeds from him ; but I must confess , it destroys the power of Immaterial substances , for Nature will not be ruled nor governed by them , and to be against Natural Immaterial substances , I think , is no Atheisme , except we make them Deities ; neither is it Atheisme to contradict the opinion of those , that believe such natural incorporeal Spirits , unless man make himself a God . But although Nature is wise , as I said before , and acts methodically , yet the variety of motions is the cause of so many Irregularities in Nature , as also the cause of Irregular opinions ; for all opinions are made by self-moving matters motions , or ( which is all one ) by corporeal self-motion , and some in their opinions do conceive Nature according to the measure of themselves , as that Nature can , nor could not do more , then they think , nay , some believe they can do as much as Nature doth ; which opinions , whether they be probable or regular , I 'le let any man judg ; adding onely this , that to humane sense and reason it appears plainly , that as God has given Nature a power to act freely , so he doth approve of her actions , being wise and methodical in all her several Productions , Generations , Transformations and Designs : And so I conclude for the present , onely subscribe my self , as really I am ,

MADAM , Your faithful Friend , and Servant .
XII . MADAM ,

I Am of your Authors opinion , concerning self-activity or self-motion , That what is Active of it self , can Of the Immortality of the Soul , l. 1. c. 7. no more cease to be active then to be : And I have been always of this opinion , even from the first begining of my conceptions in natural Philosophy , as you may see in my first Treatise of Natural Philosophy , which I put forth eleven years since ; where I say , That self-moving Matter is in a Perpetual motion ; But your Author endeavors from thence to conclude , That Matter is not self-active , because it is reducible to rest . To which I answer , That there is no such thing as Rest in Nature : Not do I say , that all sorts of motions are subject to our senses , for those that are subject to our sensitive Perceptions , are but gross Motions , in comparison to those that are not subject to our exterior senses : as for example ; We see some bodies dilate , others consume , others corrupt ; yet we do not see how they dilate , nor how they consume , nor how they corrupt : Also we see some bodies contract , some attract , some condense , some consist , &c. yet we do not see their contracting , attracting , condensing , consisting or retenting motions ; and yet we cannot say , they are not corporeal motions , because not subject to our exterior senses ; for if there were not contracting , attracting , retenting or consistent corporeal self-motions , it had been impossible that any creature could have been composed into one united figure , much less stayed and continued in the same figure without a general alteration . But your Author says , If Matter , as Matter , had Motion , nothing would hold together , but Flints , Adamants , Brass , Iron , yea , this whole Earth , would suddenly melt into a thinner substance then the subtil Air , or rather it never had been condensated together to this consistency we find it . But I would ask him , what reason he can give , that corporeal self-motion should make all matter rare and fluid , unless he believe there is but one kind of motion in Nature , but this , human sense and reason will contradict ; for we may observe there are Infinite changes of Motion , and there is more variety and curiosity in corporeal motions , then any one single Creature can imagine , much less know ; but I suppose he conceives all corporeal matter to be gross , and that not any corporeal motion can be subtil , penetrating , contracting and dilating ; and that whatsoever is penetrating , contracting and dilating , is Individable : But by his leave , Madam , this doth not follow ; for though there be gross degrees of Matter , and strong degrees of Corporeal Motions , yet there are also pure and subtil degrees of Matter and Motions ; to wit , that degree of Matter , which I name sensitive and rational Matter , which is natural Life and Knowledg , as sensitive Life and rational Knowledg . Again , your Author askes , What glue or cement holds the parts of hard matter in Stones and Metals together ? I answer , Consistent or retentive corporeal motions , by an agreeable union and conjunction in the several parts of Metal or Stone ; and these retentive or consistent motions , are as strong and active , if not more , then some dilative or contractive motions ; for I have mentioned heretofore , that , as sensitive and rational corporeal motions are in all Creatures , so also in Stone , Metal , and any other dense body whatsoever ; so that not any one Creature or part of Matter is without Motion , and therefore not any thing is at rest . But , Madam , I dare say , I could bring more reason and sense to prove , that sensitive and rational Matter is fuller of activity , and has more variety of motion , and can change its own parts of self-moving Matter more suddenly , and into more exterior figures , then Immaterial Spirits can do upon natural Matter . But your Author says , That Immaterial Spirits are endued with Sense and Reason ; I say , My sensitive and rational corporeal Matter is Sense and Reason it self , and is the Architect or Creator of all figures of Natural matter ; for though all the parts of Matter are not self-moving , yet there is not any part that is not moving or moved , by and with the mover , which is animate matter . And thus I conclude , and rest constantly ,

XIII . MADAM ,

THat Matter is uncapable of Sense , your Author proves by the example of dead Carcasses ; For , says he , Motion and Sense being really one and the Of the Imwortality of the Soul . l. 2. c. 2. same thing , it must needs follow , that where there is motion , there is also sense and perception ; but on the contrary , there is Reaction in dead Carkasses , and yet no Sense . I answer shortly , That it is no consequence , because there is no animal sense nor exterior perceptible local motion in a dead Carcass , therefore there is no sense at all in it ; for though it has not animal sense , yet it may nevertheless have sense according to the nature of that figure , into which it did change from being an animal . Also he says , If any Matter have sense , it will follow , that upon reaction all shall have the like ; and that a Bell while it is ringing , and a Bow while it is bent , and every fack-in-a-box , that School-boys play with , shall be living animals . I answer , It is true , if reaction made sense ; but reaction doth not make sense , but sense makes reaction ; and though the Bell hath not an animal knowledg , yet it may have a mineral life and knowledg , and the Bow , and the Jack-in-a-box a vegetable knowledg ; for the shape and form of the Bell , Bow , and Jack-in-a-box , is artificial ; nevertheless each in its own kind may have as much knowledg as an animal in his kind ; onely they are different according to the different proprieties of their Figures : And who can prove the contrary that they have not ? For certainly Man cannot prove what he cannot know ; but Mans nature is so , that knowing but little of other Creatures , he presently judges there is no more knowledg in Nature , then what Man , at least Animals , have ; and confines all sense onely to Animal sense , and all knowledg to Animal knowledg . Again says your Author , That Matter is utterly uncapable of such operations as we find in our selves , and that therefore there is something in us Immaterial or Incorporeal ; for we find in our selves that one and the same thing , both hears , and sees , and tastes , and perceives all the variety of objects that Nature manifests unto us . I answer , That is the reason there is but one matter , and that all natural perception is made by the animate part of matter ; but although there is but one matter in Nature , yet there are several parts or degrees , and consequently several actions of that onely matter , which causes such a variety of perceptions , both sensitive and rational : the sensitive perception is made by the sensitive corporeal motions , copying out the figures of forreign objects in the sensitive organs of the sentient ; and if those sensitive motions do pattern out forreign objects in each sensitive organ alike at one and the same time , then we hear , see , taste , touch and smell , at one and the same time : But Thoughts and Passions , as Imagination , Conception , Fancy , Memory , Love , Hate , Fear , Joy , and the like , are made by the rational corporeal motions in their own degree of matter , to wit , the rational . And thus all perception is made by one and the same matter , through the variety of its actions or motions , making various and several figures , both sensitive and rational . But all this variety in sense and reason , or of sensitive and rational perceptions , is not made by parts pressing upon parts , but by changing their own parts of matter into several figures by the power of self-motion : For example , I see a Man or Beast ; that Man or Beast doth not touch my eye in the least , neither in it self , nor by pressing the adjoyning parts : but the sensitive corporeal motions streight upon the sight of the Man or Beast make the like figure in the sensitive organ , the Eye , and in the eyes own substance or matter , as being in the eye as well as the other degrees of matter , to wit , the rational and inanimate , for they are all mixt together . But this is to be observed , That the rational matter can and doth move in its own substance , as being the purest and subtillest degree of matter ; but the sensitive being not so pure and subtil , moves always with the inanimate Matter , and so the perceptive figures which the rational Matter , or rational corporeal Motions make , are made in their own degree of Matter ; but those figures which the sensitive patterns out , are made in the organs or parts of the sentient body proper to such or such a sense or perception : as in an animal Creature , the perception of sight is made by the sensitive corporeal motions in the Eye ; the perception of hearing , in the Ear , . and so forth . As for what your Author says , That we cannot conceive any portion of Matter , but is either hard or soft ; I answer , That these are but effects of Matters actions , and so is rare , and dense , and the like ; but there are some Creatures which seem neither perfectly rare , nor dense , nor hard , nor soft , but of mixt qualities ; as for example , Quicksilver seems rare , and yet is dense ; soft , and yet is hard ; for though liquid Quicksilver is soft to our touch , and rare to our sight , yet it is so dense and hard , as not to be readily dissolved from its nature ; and if there be such contraries and mixtures in one particular creature made of self-moving Matter , what will there not be in Matter it self , according to the old saying : If the Man such praise shall have ; What the Master that keeps the knave ? So if a particular Creature hath such opposite qualities and mixtures of corporeal motions , what will the Creator have which is self-moving Matter ? Wherefore it is impossible to affirm , that self-moving Matter is either all rare , or all dense , or all hard , or all soft ; because by its self-moving power it can be either , or both , and so by the change and variety of motion , there may be soft and rare Points , and hard and sharp Points , hard and contracted Globes , and soft and rare Globes ; also there may be pressures of Parts without printing , and printing without pressures . Concerning that part of Matter which is the Common Sensorium , your Author demands , Whether some point of it receive the whole Image of the object , or whether it be wholly received into every point of it ? I answer , first , That all sensitive Matter is not in Points : Next , That not any single part can subsist of it self ; and then that one Part doth not receive all parts or any part into it self ; but that Parts by the power of self-motion can and do make several figures of all sizes and sorts , and can Epitomize a great object into a very little figure ; for outward objects do not move the body , but the sensitive and rational matter moves according to the figures of outward objects : I do not say always , but most commonly ; But , says your Author ; How can so smal a Point receive the Images of so vast or so various objects at once , without obliteration or confusion . First , I answer , That , as I said before , sensitive Matter is not bound up to a Point , nor to be a single self-subsisting Part. Next , as for confusion , I say , that the sensitive matter makes no more confusion , then an Engraver , when he engraves several figures in a small stone , and a Painter draws several figures in a small compass ; for a Carver will cut out several figures in a Cherry-stone , and a Lady in a little black Patch ; and if gross and rude Art is able to do this , why may not Ingenious and Wise Nature do ? And as Nature is ingenious and knowing in her self , so in her Parts , and her Parts in her ; for neither whole nor Parts are ignorant , but have a knowledg , each according to the motion of its own Parts ; for knowledg is in Motion , and Motion in Matter ; and the diversity and variety of motion is the diversity and variety of knowledg , so that every particular figure and motion hath its particular knowledg , as well as its proper and peculiar parts ; and as the parts join or divide , so doth knowledg , which many times causes Arts to be lost and found , and memory and remembrance in Particular Creatures : I do not say , they are utterly lost in nature , but onely in respect to particular Creatures , by the dissolving and dividing of their particular figures . For the rational matter , by reason it moves onely in its own parts , it can change and rechange into several figures without division of parts , which makes memory and remembrance : But men not considering or believing there might be such a degree of onely matter , namely rational , it has made them erre in their judgments . Nevertheless there is a difference between sensitive and rational parts and motions , and yet they are agreeable most commonly in their actions , though not always . Also the rational can make such figures as the sensitive cannot , by reason the rational has a greater power and subtiler faculty in making variety , then the sensitive ; for the sensitive is bound to move with the inanimate , but the rational moves onely in its own parts ; for though the sensitive and rational oftentimes cause each other to move , yet they are not of one and the same degree of matter , nor have they the same motions . And this rational Matter is the cause of all Notions , Conceptions , Imaginations , Deliberation , Determination , Memory , and any thing else that belongs to the Mind ; for this matter is the mind of Nature , and so being dividable , the mind of all Creatures , as the sensitive is the life ; and it can move , as I said , more subtilly , and more variously then the sensitive , and make such figures as the sensitive cannot , without outward examples and objects . But all diversity comes by change of motion , and motions are as sympathetical and agreeing , as antipathetical and disagreeing ; And though Nature's artificial motions , which are her Playing motions , are sometimes extravagant , yet in her fundamental actions there is no extravagancy , as we may observe by her exact rules in the various generations , the distinct kinds and sorts , the several exact measures , times , proportions and motions of all her Creatures , in all which her wisdom is well exprest , and in the variety her wise pleasure : To which I leave her , and rest ,

IF there be any sense and perception in Matter , says Of the Immortality of the Soul . l. 2. c. 1. a. 1 , 6 , 7. your Author , it must needs be Motion or Reaction of one part of matter against another ; and that all diversity of sense and perception doth necessarily arise from the diversity of the Magnitude , Figure , Posture , Vigour and Direction of Motion in Parts of the Matter ; In which variety of perceptions , Matter hath none , but such , as are impressed by corporeal motions , that is to say , that are perceptions of some actions , or modificated Impressions of parts of matter bearing one against another . I have declared , Madam , my opinion concerning Perception in my former Letters , that all Perception is not Impression and Reaction , like as a Seal is printed on Was : For example , the corporeal rational motions in the mind do not print , but move figuratively ; but the sensitive motions do carve , print , engrave , and , as it were , pencil out , as also move figuratively in productions , and do often take patterns from the rational figures , as the rational motions make figures according to the sensitive patterns ; But the rational can move without patterns , and so the sensitive : For surely , were a man born blind , deaf , dumb , and had a numb palsie in his exterior parts , the sensitive and rational motions would nevertheless move both in body and mind according to the nature of his figure ; for though no copies were taken from outward objects , yet he would have thoughts , passions , appetites , and the like ; and though he could not see exterior objects , nor hear exterior sounds , yet no question but he would see and hear interiously after the manner of dreams , onely they might not be any thing like to what is perceiveable by man in the World ; but if he sees not the Sun-light , yet he would see something equivalent to it ; and if he hears not such a thing as Words , yet he would hear something equivalent to words ; for it is impossible , that his sensitive and rational faculties should be lost for want of an Ear , or an Eye ; so that Perception may be without exterior object , or marks , or patterns : for although the sensitive Motions do usually pattern out the figures of exterior objects , yet that doth not prove , but they can make interior figures without such objects . Wherefore Perception is not always Reaction , neither is Perception and Reaction really one thing ; for though Perception and Action is one and the same , yet not always Reaction ; but did Perception proceed from the reaction of outward objects , a blind and deaf man would not so much as dream ; for he would have no interior motion in the head , having no other exterior sense but touch , which , if the body was troubled with a painful disease , he would neither be sensible of , but to feel pain , and interiously feel nothing but hunger and fulness ; and his Mind would be as Irrational as some imagine Vegetables and Minerals are . To which opinion I leave them , and rest ,

YOur Author is pleased , in Mirth , and to disgrace the opinion of those which hold , that Perception is made by figuring , to bring in this following example : Suppose , says he , one Particle should shape it self into a George on Horse-back with a Lance in his hand , In the second Book of the Immortality of the Soul , ch. 6. and another into an Inchanted Castle ; this George on Horse-back must run against the Castle , to make the Castle receive his impress and similitude : But what then ? Truly the Encounter will be very Vnfortunate , for S. George indeed may easily break his Lance , but it is impossible that he should by justling against the Particle in the form of a Castle , conveigh the intire shape of himself and his Horse thereby , such as we find our selves able to imagine of a man on Horse-back ; which is a Truth as demonstrable as any Theorem in Mathematicks . I answer , first , That there is no Particle single and alone by it self ; Next , I say , It is more easie for the rational matter to put it self into such figures , and to make such encounters , then for an Immaterial mind or sustance to imagine it ; for no imagination can be without figure , and how should an Immaterial created substance present such Figures , but by making them either in it self or upon matter ? For S. George and the Castle are figures , and their encounters are real fighting actions , and how such figures and actions can be in the mind or memory , and yet not be , is impossible to conceive ; for , as I said , those figures and actions must be either in the incorporeal mind , or in the corporeal parts of matter ; and if the figures and motions may be in an incorporeal substance , much more is it probable for them to be in a corporeal ; nay if the figures and their actions can be in gross corporeal matter , why should they not be in the purest part of matter , which is the rational matter ? And as for being made known to the whole body , and every part thereof , it is not necessary , no more then it is necessary , that the private actions of every Man or Family should be made known to the whole Kingdom , or Town , or Parish : But my opinion of self-corporeal motion and perception , may be as demonstrable as that of Immaterial Natural Spirits , which , in my mind , is not demonstrable at all , by reason it is not corporeal or material ; For how can that be naturally demonstrable , which naturally is nothing ? But your Author believes the Mind or rational Soul to be individable , and therefore concludes , that the Parts of the same Matter , although at great distance , must of necessity know each Particular act of each several Part ; but that is not necessary ; for if there were not ignorance through the division of Parts , every man and other creatures would know alike ; and there is no better proof , that matter , or any particular creature in nature is not governed by a created Immaterial Spirit , then that knowledg is in parts ; for the hand doth not know what pain the head feels , which certainly it would do , if the mind were not dividable into parts , but an individable substance . But this is well to be observed , that some parts in some actions agree generally in one body , and some not ; as for example , temperance and appetite do not agree ; for the corporeal actions of appetite desire to join with the corporeal actions of such or such other parts , but the corporeal actions of temperance do hinder and forbid it ; whereupon there is a faction amongst the several parts : for example , a Man desires to be drunk with Wine ; this desire is made by such corporeal actions as make appetite ; the rational corporeal motions or actions which make temperance , oppose those that make appetite , and that sort of actions which hath the better , carryes it , the hand and other parts of the body obeying the strongest side ; and if there be no wine to satisfie the appetite , yet many times the appetite continues ; that is , the parts continue in the same motions that make such an appetite ; but if the appetite doth not continue , then those parts have changed their motions ; or when by drinking , the appetite is satisfied , and ceases , then those parts that made the appetite , have altered their former motions . But oftentimes the rational corporeal motions may so agree with the sensitive , as there may be no opposition or crossing at all , but a sympathetical mutual agreement betwixt them , at least an approvement ; so that the rational may approve what the sensitive covet or desire : Also some motions of the rational , as also of the sensitive matter , may disagree amongst themselves , as we see , that a man will often have a divided mind ; for he will love and hate the same thing , desire and not desire one and the same thing , as to be in Heaven , and yet to be in the World : Moreover , this is to be observed , That all rational perceptions or cogitations , are not so perspicuous and clear as if they were Mathematical Demonstrations , but there is some obscurity , more or less in them , at least they are not so well perceivable without comparing several figures together , which proves , they are not made by an individable , immaterial Spirit , but by dividable corporeal parts : As for example , Man writes oftentimes false , and seldom so exact , but he is forced to mend his hand , and correct his opinions , and sometimes quite to alter them , according as the figures continue or are dissolved and altered by change of motion , and according as the actions are quick or slow in these alterations , the humane mind is setled or wavering ; and as figures are made , or dissolved and transformed , Opinions , Conceptions , Imaginations , Understanding , and the like , are more or less ; And according as these figures last , so is constancy or inconstancy , memory or forgetfulness , and as those figures are repeated , so is remembrance ; but sometimes they are so constant and permanent , as they last as long as the figure of the body , and sometimes it happens not once in an age , that the like figures are repeated , and sometimes they are repeated every moment : As for example ; a man remembers or calls to mind the figure of another man , his friend , with all his qualities , dispositions , actions , proprieties , and the like , several times in an hour , and sometimes not once in a year , and so as often as he remembers him , as often is the figure of that man repeated ; and as oft as he forgets him , so often is his figure dissolved . But some imagine the rational motions to be so gross as the Trotting of a Horse , and that all the motions of Animate matter are as rude and course as renting or tearing asunder , or that all impressions must needs make dents or creases . But as Nature hath degrees of corporeal matter , so she hath also degrees of corporeal motions , Matter and Motion being but one substance ; and it is absurd to judg of the interior motions of self-moving matter , by artificial or exterior gross motions , as that all motions must be like the tearing of a sheet of Paper , or that the printing and patterning of several figures of rational and sensitive matter must be like the printing of Books ; nay , all artificial Printings are not so hard , as to make dents and impresses ; witness Writing , Painting , and the like ; for they do not disturb the ground whereon the letters are written , or the picture drawn , and so the curious actions of the purest rational matter are neither rude nor rough ; but although this matter is so subtil and pure , as not subject to exterior human senses and organs , yet certainly it is dividable , not onely in several Creatures , but in the several parts of one and the same Creature , as well as the sensitive , which is the Life of Nature , as the other is the Soul ; not the Divine , but natural Soul ; neither is this Soul Immaterial , bnt Corporeal ; not composed of raggs and shreds , but it is the purest , simplest and subtillest matter in Nature . But to conclude , I desire you to remember , Madam , that this rational and sensitive Matter in one united and finite Figure or particular Creature , has both common and particular actions ; for as there are several kinds and sorts of Creatures , and particulars in every kind and sort : so the like for the actions of the rational and sensitive matter in one particular Creature . Also it is to be noted , That the Parts of rational matter , can more suddenly give and take Intelligence to and from each other , then the sensitive ; nevertheless , all Parts in Nature , at least adjoyning parts , have Intelligence between each other , more or less , because all parts make but one body ; for it is not with the parts of Matter , as with several Constables in several Hundreds , or several Parishes , which are a great way distant from each other , but they may be as close as the combs of Bees , and yet as partable and as active as Bees . But concerning the Intelligence of Natures Parts , I have sufficiently spoken in other places ; and so I 'le add no more , but that I unfeignedly remain ,

SEnsation in corporeal motion is first , and Perception In the Pref. of the Imm. of the Soul . follows , sayes your Author : to which opinion I give no assent , but do believe that Perception and Sensation are done both at one and the same time , as being one and the same thing without division , either in reason or sense , and are performed without any knocks , or jolts , or hitting against . But let me tell you , Madam , there arises a great mistake by many , from not distinguishing well , sensitive Motion , and rational Motion ; for though all motions are in one onely matter , yet that matter doth not move always in the same manner , for then there could be no variety in Nature ; and truly , if man , who is but a part of Nature , may move diversly , and put himself into numerous postures ; Why may not Nature ? But concerning Motions , and their variety , to avoid tedious repetitions , I must still referr you to my Book of Philosophical Opinions ; I 'le add onely this , that it is well to be observed , That all Motions are not Impressions , neither do all Impressions make such dents , as to disturb the adjoyning Parts : Wherefore those , in my opinion , understand Nature best , which say , that Sensation and Perception are really one and the same ; but they are out , that say , there can be no communication at a distance , unless by pressing and crowding ; for the patterning of an outward object , may be done without any inforcement or disturbance , jogging or crowding , as I have declared heretofore ; for the sensitive and rational motions in the sensitive and rational parts of matter in one creature , observing the exterior motions in outward objects , move accordingly , either regularly or irregularly in patterns ; and if they have no exterior objects , as in dreams , they work by rote . And so to conclude , I am absolutely of their opinion , who believe , that there is nothing existent in Nature , but what is purely Corporeal , for this seems most probable in sense and reason to me ,

OUtward Objects , as I have told you before , do not make Sense and Reason , but Sense and Reason do perceive and judg of outward objects ; For the Sun doth not make sight , nor doth sight make light ; but sense and reason in a Man , or any other creature , do perceive and know there are such objects as Sun , and Light , or whatsoever objects are presented to them . Neither doth Dumbness , Deafness , Blindness , &c. cause an Insensibility , but Sense through irregular actions causes them ; I say , through Irregular actions , because those effects do not properly belong to the nature of that kind of Creatures ; for every Creature , if regularly made , hath particular motions proper to its figure ; for natural Matters wisdom makes distinctions by her distinct corporeal motions , giving every particular Creature their due Portion and Proportion according to the nature of their figures , and to the rules of her actions , but not to the rules of Arts , Mathematical Compasses , Lines , Figures , and the like . And thus the Sun , Stars , Meteors , Air , Fire , Water , Earth , Minerals , Vegetables and Animals , may all have Sense and Reason , although it doth not move in one kind or sort of Creatures , or in one particular , as in another : For the corporeal motions differ not onely in kinds and sorts , but also in Particulars , as is perceivable by human sense and reason ; Which is the cause , that Elements have elemental sense and knowledg , and Animals animal sense and knowledg , and so of Vegetables , Minerals , and the like . Wherefore the Sun and Stars may have as much sensitive and rational life and knowledg as other Creatures , but such as is according to the nature of their figures , and not animal , or vegetable , or mineral sense and knowledg . And so leaving them , I rest ,

YOur Author denying that Fancy , Reason and Animadversion are seated in the Brain , and that the Brain is figured into this or that Conception : Antid. lib. 1. c. 11. I demand , says he , in what knot , loop or interval thereof doth this faculty of free Fancy and active Reason reside ? My answer is , that in my opinion , Fancy and Reason are not made in the Brain , as there is a Brain , but as there is sensitive and rational matter , which makes not onely the Brain , but all Thoughts , Conceptions , Imaginations , Fancy , Understanding , Memory , Remembrance , and whatsoever motions are in the Head , or Brain : neither doth this sensitive and rational mattet remain or act in one place of the Brain , but in every part thereof ; and not onely in every part of the Brain , but in every part of the Body ; nay , not onely in every part of a Mans Body , but in every part of Nature . But , Madam , I would ask those , that say the Brain has neither sense , reason , nor self-motion , and therefore no Perception ; but that all proceeds from an Immaterial Principle , as an Incorporeal Spirit , distinct from the body , which moveth and actuates corporeal matter ; I would fain ask them , I say , where their Immaterial Ideas reside , in what part or place of the Body ? and whether they be little or great ? Also I would ask them , whether there can be many , or but one Idea of God ? If they say many , then there must be several , distinct Deitical Ideas ; if but one , Where doth this Idea reside ? If they say in the head , then the heart is ignorant of God ; if in the heart , then the head is ignorant thereof , and so for all parts of the body ; but if they say , in every part , then that Idea may be disfigured by a lost member ; if they say , it may dilate and contract , then I say it is not the Idea of God , for God can neither contract nor extend ; nor can the Idea it self dilate and contract , being immaterial ; for contraction and dilation belong onely to bodies , or material beings : Wherefore the comparisons betwixt Nature and a particular Creature , and between God and Nature , are improper ; much more betwixt God and Natures particular motions and figures , which are various and changeable , although methodical . The same I may ask of the Mind of Man , as I do of the Idea in the Mind . Also I might ask them , what they conceive the natural mind of man to be ; whether material or immaterial ? If material , their opinion is rational , and so the mind is dividable and composable ; if immaterial , then it is a Spirit ; and if a Spirit , it cannot possibly dilate nor contract , having no dimension nor divisibility of parts , ( although your Author proves it by the example of Light ; but I have exprest my meaning heretofore , that light is divisible ) and if it have no dimension , how can it be confined in a material body ? Wherefore when your Author says , the mind is a substance , it is to my reason very probable ; but not when he says , it is an immaterial substance , which will never agree with my sense and reason ; for it must be either something , or nothing , there being no medium between , in Nature . But pray mistake me not , Madam , when I say Immaterial is nothing ; for I mean nothing Natural , or so as to be a part of Nature ; for God forbid , I should deny , that God is a Spiritual Immaterial substance , or Being ; neither do I deny that we can have an Idea , notion , conception , or thought of the Existence of God ; for I am of your Authors opinion , That there is no Man under the cope of Heaven , that doth not by the light of Nature , know , and believe there is a God ; but that we should have such a perfect Idea of God , as of any thing else in the World , or as of our selves , as your Author says , I cannot in sense and reason conceive to be true or possible . Neither am I against those Spirits , which the holy Scripture mentions , as Angels and Devils , and the divine Soul of Man ; but I say onely , that no Immaterial Spirit belongs to Nature , so as to be a part thereof ; for Nature is Material , or Corporeal ; and whatsoever is not composed of matter or body , belongs not to Nature ; nevertheless , Immaterial Spirits may be in Nature , although not parts of Nature . But there can neither be an Immaterial Nature , nor a Natural Immaterial ; Nay , our very thoughts and conceptions of Immaterial are Material , as made of self-moving Matter . Wherefore to conclude , these opinions in Men proceed from a Vain-glory , as to have found out something that is not in Nature ; to which I leave them , and their natural Immaterial Substances , like so many Hobgoblins to fright Children withal , resting in the mean time ,

THere are various opinions concerning the seat of Common Sense , as your Author rehearseth them in his Treatise of the Immortality of the Soul ; Lib. 2. c. 4. But my opinion is , That common sense hath also a common place ; for as there is not any part of the body that hath not sense and reason , so sense and reason is in all parts of the body , as it is observable by this , that every part is subject to pain and pleasure , and all parts are moveable , moving and moved ; also appetites are in every part of the body : As for example , if any part itches , it hath an appetite to be scratched , and every part can pattern out several objects , and so several touches ; and though the rational part of matter is mixt in all parts of the body , yet it hath more liberty to make variety of Motions in the head , heart , liver , spleen , stomack , bowels , and the like , then in the other parts of the body ; nevertheless , it is in every part , together with the sensitive : but they do not move in every part alike , but differ in each part more or less , as it may be observed ; and although every part hath some difference of knowledg , yet all have life and knowledg , sense and reason , some more , some less , and the whole body moves according to each part , and so do all the bodily Faculties and Proprieties , and not according to one single part ; the rational Soul being in all parts of the body : for if one part of the body should have a dead Palsie , it is not , that the Soul is gone from that part , but that the sensitive and rational matter has altered its motion and figure from animal to some other kind ; for certainly , the rational Soul , and so life , is in every part , as well in the Pores of the skin , as in the ventricles of the brain , and as well in the heel as in the head ; and every part of the body knows its own office , what it ought to do , from whence follows an agreement of all the parts : And since there is difference of knowledg in every part of one body , well may there be difference between several kinds and sorts , and yet there is knowledg in all ; for difference of knowledg is no argument to prove they have no knowledg at all . Wherefore I am not of the opinion , that that which moves the whole body , is as a Point , or some such thing in a little kernel or Glandula of the Brain , as an Ostrich-egge is hung up to the roof of a Chamber ; or that it is in the stomack like a single penny in a great Purse ; neither is it in the midst of the heart , like a Lady in a Lobster ; nor in the bloud , like as a Menow , or Sprat in the Sea ; nor in the fourth Ventricle of the Brain , as a lousie Souldier in a Watch-tower . But you may say , it is like a farthing Candle in a great Church : I answer , That Light will not enlighten the by Chappels of the Church , nor the Quest-house , nor the Belfrey ; neither doth the Light move the Church , though it enlightens it : Wherefore the Soul after this manner doth not move the corporeal body , no more then the Candle moves the Church , or the Lady moves the Lobster , or the Sprat the Sea as to make it ebb and flow . But this I desire you to observe , Madam , that though all the body of man or any other Creature , hath sense and reason , which is life and knowledg , in all parts , yet these parts being all corporeal , and having their certain proportions , can have no more then what is belonging or proportionable to each figure : As for example ; if a Man should feed , and not evacuate some ways or other , he could not live ; and if he should evacuate and not feed , he could not subsist : wherefore in all Natures parts there is ingress and egress , although not always perceived by one creature , as Man ; but all exterior objects do not enter into Man , or any other Creature , but are figured by the rational , and some by the sensitive parts or motions in the body ; wherefore it is not rational to believe , that exterior objects take up any more room , then if there were none presented to the sensitive organs : Nor is there any thing which can better prove the mind to be corporeal , then that there may be several Figures in several parts of the body made at one time , as Sight , Hearing , Tasting , Smelling , and Touching , and all these in each several organ , as well at one , as at several times , either by patterns , or not ; which figuring without Pattern , may be done as well by the sensitive motions in the organs , as by the rational in the mind , and is called remembrance . As for example : a Man may hear or see without an object ; which is , that the sensitive and rational matter repeat such figurative actions , or make others in the sensitive organs , or in the mind : and Thoughts , Memory , Imagination , as also Passion , are no less corporeal actions then the motion of the hand or heel ; neither hath the rational matter , being naturally wise , occasion to jumble and knock her parts together , by reason every part knows naturally their office what they ought to do , or what they may do . But I conclude , repeating onely what I have said oft before , that all Perceptions , Thoughts , and the like , are the Effects , and Life and Knowledg , the Nature and Essence of self-moving Matter . And so I rest ,

IAm not able to conceive how the Mind of Man can be compared to a Table-book , in which nothing Antid. Book . 1. c. 5. is writ ; nor how to a Musician , who being asleep , doth not so much as dream of any Musick , but being jogg'd and awakend by another , who tells him two or three words of a Song , and desires him to sing it , presently recovers himself , and sings upon so slight an Intimation : For such intimations are nothing else but outward objects , which the interior sense consents to , and obeys ; for interior sense and reason doth often obey outward objects : and in my opinion there is no rest in Nature , and so neither in the Mind or natural Soul of Man , which is in a perpetual motion , and needs therefore no jogging to put it into any actual motion ; for it hath actual motion and knowledg in it self , because it is a self-moving substance , actually knowing , and Material or Corporeal , not Immaterial , as your Author thinks : and this material or corporeal Mind is nothing else but what I call the rational matter , and the corporeal life is the sensitive matter . But this is to be observed , that the motions of the corporeal Mind do often imitate the motions of the sensitive Life , and these again the motions of the mind : I say oftentimes ; for they do it not always , but each one can move without taking any pattern from the other . And all this I understand of the Natural Soul of Man ; not of the Divine Soul , and her powers and faculties , for I leave that to Divines to inform us of ; onely this I say , that men not conceiving the distinction between this natural and divine Soul , make such a confusion betwixt those two Souls and their actions , which causes so many disputes and opinions . But if Nature hath power from God to produce all kinds of Vegetables , Minerals , Elements , Animals , and other sorts of Creatures , Why not also Man ? Truly if all Creatures are natural Creatures , Man must be so too ; and if Man is a natural Creature , he must needs have natural sense and reason , as well as other Creatures , being composed of the same matter they are of . Neither is it requisite , that all Creatures , being of the same matter , must have the same manner of sensitive and rational knowledg ; which if so , it is not necessary for Corn to have Ears to hear the whistling or chirping of Birds , nor for Stones to have such a touch of feeling as animals have , and to suffer pain , as they do , when Carts go over them ; as your Author is pleased to argue out of AEsopes Tales ; or for the Heliotrope to have eyes to see the Sun : for what necessity Ch. 3. is there that they should have humane sense and reason ? which is , that the rational and sensitive matter should act and move in them as she doth in man or animals : Certainly if there must be any variety in nature , it is requisite she should not ; wherefore all Vegetables , Minerals , Elements , and Animals , have their proper motions different from each others , not onely in their kinds and sorts , but also in their particulars . And though Stones have no progressive motion to withdraw themselves from the Carts going over them , which your Author thinks they would do , if they had sense , to avoid pain : nevertheless they have motion , and consequently sense and reason , according to the nature and propriety of their figure , as well as man has according to his . But this is also to be observed , that not any humane Creature , which is accounted to have the perfectest sense and reason , is able always to avoid what is hurtful or painful , for it is subject to it by Nature : Nay , the Immaterial Soul it self , according to your Author , Append. to the Antid. ch. 3. cannot by her self-contracting faculty withdraw her self from pain . Wherefore there is no manner of consequence to conclude from the sense of Animals to the sense of Minerals , they being as much different as their Figures are ; And saying this , I have said enough to express the opinion and mind of ,

MADAM , Your faithful Friend and Servant .
XXI . MADAM ,

YOur Author endeavours very much to prove the Existency of a Natural Immaterial Spirit , whom he defines to be an Incorporeal substance , Indivisible , that can move it self , can penetrate , contract and dilate it self , and can also move and alter the matter . Whereof , if you will have my opinion , I confess freely to you , that in my sense and reason I cannot conceive it to be possible , that there is any such thing in Nature ; for all that is a substance in Nature , is a body , and what has a body , is corporeal ; for though there be several degrees of matter , as in purity , rarity , subtilty , activity ; yet there is no degree so pure , rare and subtil , that can go beyond its nature , and change from corporeal to incorporeal , except it could change from being something to nothing , which is impossible in Nature . Next , there is no substance in Nature that is not divisible ; for all that is a body , or a bodily substance , hath extension , and all extension hath parts , and what has parts , is divisible . As for self-motion , contraction and dilation , these are actions onely of Natural Matter ; for Matter by the Power of God is self-moving , and all sorts of motions , as contraction , dilation , alteration , penetration , &c. do properly belong to Matter ; so that natural Matter stands in no need to have some Immaterial or Incorporeal substance to move , rule , guide and govern her , but she is able enough to do it all her self , by the free Gift of the Omnipotent God ; for why should we trouble our selves to invent or frame other unconceivable substances , when there is no need for it , but Matter can act , and move as well without them and of it self ? Is not God able to give such power to Matter , as to an other Incorporeal substance ? But I suppose this opinion of natural Immaterial Spirits doth proceed from Chymistry , where the extracts are vulgarly called Spirits ; and from that degree of Matter , which by reason of its purity , subtilty and activity , is not subject to our grosser senses ; However , these are not Incorporeal , be they never so pure and subtil . And I wonder much that men endeavour to prove Immaterial Spirits by corporeal Arts , when as Art is not able to demonstrate Nature and her actions ; for Art is but the effect of Nature , and expresses rather the variety , then the truth of natural motions ; and if Art cannot do this , much less will it be able to express what is not in Nature , or what is beyond Nature ; as to trace the Visible ( or rather Invisible ) footsteps of the divine Councel and Providence , or Antid. lib. 2. ch. 2. to demonstrate things supernatural , and which go beyond mans reach and capacity . But to return to Immaterial Spirits , that they should rule and govern infinite corporeal matter , like so many demy-Gods , by a dilating nod , and a contracting frown , and cause so many kinds and sorts of Corporeal Figures to arise , being Incorporeal themselves , is Impossible for me to conceive ; for how can an Immaterial substance cause a Material corporeal substance , which has no motion in it self , to form so many several and various figures and creatures , and make so many alterations , and continue their kinds and sorts by perpetual successions of Particulars ? But perchance the Immaterial substance gives corporeal matter motion . I answer , My sense and reason cannot understand , how it can give motion , unless motion be different , distinct and separable from it ; nay , if it were , yet being no substance or body it self , according to your Authors and others opinion , the question is , how it can be transmitted or given away to corporeal matter ? Your Author may say , That his Immaterial and Incorporeal spirit of Nature , having self-motion , doth form Matter into several Figures : I answer , Then that Immaterial substance must be transformed and metamorphosed into as many several figures as there are figures in Matter ; or there must be as many spirits , as there are figures ; but when the figures change , what doth become of the spirits ? Neither can I imagine , that an Immaterial substance , being without body , can have such a great strength ; as to grapple with gross , heavy , dull , and dead Matter ; Certainly , in my opinion , no Angel , nor Devil , except God Impower him , would be able to move corporeal Matter , were it not selfmoving , much less any Natural Spirit . But God is a Spirit , and Immovable ; and if created natural Immaterials participate of that Nature , as they do of the Name , then they must be Immovable also . Your Author , Madam , may make many several degrees of Spirits ; but certainly not I , nor I think any natural Creature else , will be able naturally to conceive them . He may say , perchance , There is such a close conjunction betwixt Body and Spirit , as I make betwixt rational , sensitive , and inanimate Matter . I answer , That these degrees are all but one Matter , and of one and the same Nature as meer Matter , different onely in degrees of purity , subtilty , and activity , whereas Spirit and Body are things of contrary Natures . In fine , I cannot conceive , how a Spirit should fill up a place or space , having no body , nor how it can have the effects of a body , being none it self ; for the effects flow from the cause ; and as the cause is , so are its effects : And so confessing my ignorance , I can say no more , but rest ,

YOur Author having assigned Indivisibility to the Soul or Spirit that moves and actuates matter , I desire to know , how one Indivisible Spirit can be in so many dividable parts ? For there being Infinite parts in Nature , they must either have one Infinite Spirit to move them , which must be dilated infinitely , or this Spirit must move severally in every part of Nature : If the first , then I cannot conceive , but all motion must be uniform , or after one and the same manner ; nay , I cannot understand , how there can be any dilation and contraction , or rather any motion of the same spirit , by reason if it dilate , then , ( being equally spread out in all the parts of Matter , ) it must dilate beyond Matter ; and if it contract , it must leave some parts of matter void , and without motion . But if the Spirit moves every part severally , then he is divisible ; neither can I think , that there are so many Spirits as there are Parts in Nature ; for your Author says , there is but one Spirit of Nature ; I will give an easie and plain example : When a Worm is cut into two or three parts , we see there is sensitive life and motion in every part , for every part will strive and endeavour to meet and joyn again to make up the whole body ; now if there were but one indivisible Life , Spirit , and Motion , I would fain know , how these severed parts could move all by one Spirit . Wherefore , Matter , in my opinion , has self-motion in it self , which is the onely soul and life of Nature , and is dividable as well as composable , and full of variety of action ; for it is as easie for several parts to act in separation , as in composition , and as easie in composition as in separation ; Neither is every part bound to one kind or sort of Motions ; for we see in exterior local motions , that one man can put his body into several shapes and postures , much more can Nature . But is it not strange , Madam , that a man accounts it absurd , ridiculous , and a prejudice to Gods Omnipotency , to attribute self-motion to Matter , or a material Creature , when it is not absurd , ridiculous , or any prejudice to God , to attribute it to an Immaterial Creature ? What reason of absurdity lies herein ? Surely I can conceive none , except it be absurd and ridiculous to make that , which no man can know or conceive what it is , viz. an immaterial natural Spirit , ( which is as much as to say , a natural No-thing ) to have motion , and not onely motion , but self-motion ; nay , not onely self-motion , but to move , actuate , rule , govern , and guide Matter , or corporeal Nature , and to be the cause of all the most curious varieties and effects in nature : Was not God able to give self-motion as well to a Material , as to an Immaterial Creature , and endow Matter with a self-moving power ? I do not say , Madam , that Matter hath motion of it self , so , that it is the prime cause and principle of its own self-motion ; for that were to make Matter a God , which I am far from believing ; but my opinion is , That the self-motion of Matter proceeds from God , as well as the self-motion of an Immaterial Spirit ; and that I am of this opinion , the last Chapter of my Book of Philosophy will enform you , where I treat of the Deitical Centre , as the Fountain from whence all things do flow , and which is the supream Cause , Author , Ruler and Governor of all . Perhaps you will say , it is , because I make Matter Eternal . T is true , Madam , I do so : but I think Eternity doth not take off the dependance upon God , for God may nevertheless be above Matter , as I have told you before . You may ask me how that can be ? I say , As well as any thing else that God can do beyond our understanding : For I do but tell you my opinion , that I think it most probable to be so , but I can give you no Mathematical Demonstrations for it : Onely this I am sure of , That it is not impossible for the Omnipotent God ; and he that questions the truth of it , may question Gods Omnipotency . Truly , Madam , I wonder how man can say , God is Omnipotent , and can do beyond our Understanding , and yet deny all that he is not able to comprehend with his reason . However , as I said , it is my opinion , That Matter is self-moving by the power of God ; Neither can Animadversion , and Perception , as also the variety of Figures , prove , that there must be another external Agent or Power to work all this in Matter ; but it proves rather the contrary ; for were there no self-motion in Matter , there would be no Perception , nor no variety of Creatures in their Figures , Shapes , Natures , Qualities , Faculties , Proprieties , as also in their Productions , Creations or Generations , Transformations , Compositions , Dissolutions , and the like , as Growth , Maturity , Decay , &c. and for Animals , were not Corporeal Matter self-moving , dividable and composable , there could not be such variety of Passions , Complexions , Humors , Features , Statures , Appetites , Diseases , Infirmities , Youth , Age , &c. Neither would they have any nourishing Food , healing Salves , soveraign Medicines , reviving Cordials , or deadly Poysons . In short , there is so much variety in Nature , proceeding from the self-motion of Matter , as not possible to be numbred , nor thorowly known by any Creature : Wherefore I should labour in vain , if I endeavoured to express any more thereof ; and this is the cause that I break off here , and onely subscribe my self ,

COncerning the comparison , your Author makes In the Append . to the Antid. c. 3. and Of the Immortality of the Soul , l. 1. c. 5. between an Immaterial Spirit , and Light , That , as Light is contractive and dilative , and yet not divisible , so is also an Immaterial substance . Give me leave to tell you , that in my opinion , all that is contractive and dilative , is also dividable , and so is light : As for example ; when a Candle is snuff'd , the Snuffers do not onely clip the wick , but also the light : The like when a dark body is interposed , or crosses the rays of the Sun ; it cuts those rays asunder , which by reason they cannot joyn together again , because of the interposed body , the light cut off , suddenly goeth out ; that is , the matter of light is altered from the figure of light , to some other thing , but not annihilated : And since no more light can flow into the room from the Fountain or Spring of Light , the Sun , because the passage is stopt close , the room remaineth dark : For Light is somewhat of the nature of Water ; so long as the Spring is open , the Water flows , and whatsoever is taken away , the Spring supplies ; and if another body onely presses thorow it , it immediately joyns and closes its severed parts again , without any difficulty or loss ; The same doth Light ; onely the difference is , that the substance of Light is extraordinary rare , and pure ; for as Air is so much rarer then Water , so Light is so much rarer and purer then Air , and its matter may be of so dilating a nature , as to dilate from a point into numerous rayes . As for ordinary Fire-light , it doth not last longer , then it hath fuel to feed it , and so likewise it is with the light of the Sun ; for Light is according to the substance that feeds it ; and though it is a substance it self , yet it increases and decreases , according as it hath something that succours or nourishes it . But some may object , that if Light were a body , and did contract and dilate , as I say , it is impossible that it could display it self in so great and vast a compass , and remove so suddenly and instantly as it doth . To which objection , I answer , first , That although I say , Light is a real corporeal substance , and doth contract and dilate it self from a point into numerous rayes , as also in another Letter I sent you before Sect. 1. Let. 20. , That Light and Darkness do succeed each other ; nevertheless , as for the perception of Light , I am not so eager in maintaining this opinion , as if it was an Infallible Truth , and impossible to be otherwise ; but I say onely , That , to my sense and reason , it seems very probable , that it may be so , that the light of the Sun doth really dilate it self into so vast a compass as we see ; and that light and darkness do really succeed each other , as all other Creatures do : But yet it seems also probable to mee , that the parts of the Air may onely pattern out the figure of light , and that the light we see in the Air may be onely patterns taken from the real figure of the light of the Sun : And therefore , if it be according to the former opinion , to wit , That the light of the Sun doth really dilate it self into so vast a compass , My answer is , That contraction and dilation are natural corporeal actions or motions , and that there is no alteration of motion in Nature , but is done in Time , that is , successively , not instantly ; for Time is nothing else but the alteration of motion : Besides , I do not perceive any so sudden and swift alteration and succession of light , but that it is done by degrees : As for example ; in the morning , when it begins to dawn and grow light , it appears clearly to our sight how light doth come forth , and darkness remove by degrees ; and so at night , when it grows dark , how light removes , and darkness succeeds ; nay , if there be any such sudden change of the motions of Light , I desire you to consider , Madam , that light is a very subtil , rare , piercing and active body , and therefore its motions are much quicker then those of grosser bodies , and cannot so well be perceived by our gross exterior senses . But if it be , that the Air doth pattern out the light of the Sun , then the framed objection can prove nothing , because there is not then such a real dilation or succession of light , but the corporeal figurative motions of the Air do make patterns of the light of the Sun , and dissolve those patterns or figures again , more suddenly and quickly then man can shut and open his eyes , as being more subtil then his gross exterior senses . But it may be said , that if Air did pattern out the light of the Sun , the light would increase by these numerous patterns . I answer , that cannot appear to our Eyes ; for we see onely the pattern'd figure of light , and that a great compass is enlightned ; also that the further the air is from the Sun , the darker it is ; nevertheless , I do verily believe , that the body of the Sun is far brighter then the light we see , and that the substance of light , and the patterns taken from light , are not one and the same , but very different . And thus much of light . As for Penetration , I conceive it to be nothing else but division ; as when some parts pierce and enter through other parts , as Duellers run each other thorow , or as water runs through a sieve . And this is the opinion of ,

HAving given you my opinion , both of the substance and perception of Light , in my last Letter , I perceive your desire is to know how Shadows are made . Truly , Madam , to my sense and reason , it appears most probable , that shadows are made by the way of patterning : As for example ; when a Man 's , or Trees , or any other the like Creature 's shadow is made upon the Ground , or Wall , or the like ; those bodies , as the Ground , or Wall , do , in my opinion , pattern out the interposing body that is between the light and them : And the reason that the shadow is longer or shorter , or bigger or less , is according as the light is nearer or further off ; for when the light is perpendicular , the interposing body cannot obscure the light , because the light surrounding the interposing body by its brightness , rather obscures the body , then the body the light ; for the numerous and splendorous patterns of light taken from the body of the Sun , do quite involve the interposing body . Next , you desire to know , Whether the light we see in the Moon , be the Moons own natural light , or a borrowed light from the Sun : I answer , that in my opinion , it is a borrowed light ; to wit , that the Moon doth pattern out the light of the Sun : and the proof of it is , that when the Sun is in an Eclipse , we do plainly perceive that so much of the Sun is darkned as the Moon covers ; for though those parts of the Moon , that are next the Sun , may , for any thing we know , pattern out the light of the Sun , yet the Moon is dark on that side which is from the Sun . I will not say , but that part of the Moon which is towards the Earth , may pattern out the Earth , or the shadow of the Earth , which may make the Moon appear more dark and sullen ; But when the Moon is in an Eclipse , then it is plainly perceived that the Moon patterns out the Earth , or the shadow of the Earth . Besides , those parts of the Moon that are farthest from the Sun , are dark , as we may observe when as the Moon is in the Wane , and enlightened when the Sun is nearer . But I will leave this argument to observing Astrologers , and rest ,

IF acording to your Authors opinion , In every particular world , such as Man is especially , his own Soul ( which is a Spirit ) be the peculiar and most perfective architect of the Fabrick of his Body , as the Soul of the Of the Immortality of the Soul . l. 2. c. 10. world is of it : Then I cannot conceive in my reason , how the separation is made in death ; for I see , that all animals , and so man-kind , have a natural desire to live , and that life and soul are unwilling to part ; And if the power lies in the Soul , why doth she not continue with the Body , and animate , move and actuate it , as she did before , or order the matter so , as not to dissolve ? But if the dissolution lies in the body , then the body has self-motion : Yet it is most probable , if the soul be the architect of the body , it must also be the dissolver of it ; and if there come not another soul into the parts of matter , the body must either be annihilated , or lie immoved as long as the world lasts , which is improbable ; for surely all the bodies of men , or other animals , are imployed by Nature to some use or other : However , it is requisite , that the soul must stay so long in the body , until it be turned into dust and ashes ; otherwise , the body having no self-motion , would remain as it was when the soul left it , that is , entire and undissolved : As for example ; when a man dies , if there be no motion in his body , and the soul , which was the mover , be gone , it cannot possibly corrupt ; for certainly , that we call corruptton , is made by motion , and the body requires as much motion to be dissolved or divided , as it doth to be framed or composed ; Wherefore a dead body would remain in the same state continually , if it had no self-motion in it : And if another soul should enter into the body , and work it to another figure , then certainly there must be much more souls then bodies , because bodies are subject to change into several forms ; but if the animal spirits , which are left in the body after the soul is gone , are able to dissolve it without the help of the soul , then it is probable they could have fram'd it without the help of the soul ; and so they being material , it must be granted , that matter is self-moving : But if corporeal matter have corporeal self-motion , a self-moving Immaterial Spirit , by reason of their different natures , would make great obstruction , and so a general confusion ; for the corporeal and incorporeal motions would hinder and oppose each other , their natures being quite different ; and though they might subsist together without disturbance of each other , yet it is not probable they should act together , and that in such a conjunction , as if they were one united body ; for it is , in my opinion , more probable , that one material should act upon another material , or one immaterial upon another immaterial , then that an immaterial should act upon a material or corporeal . Thus the consideration or contemplation of immaterial natural Spirits puts me always into doubts , and raises so many contradictions in my sense and reason , as I know not , nor am not able to reconcile them : However , though I am doubtful of them , yet I can assure your self that I continue ,

BY reason the Soul is a Spirit , and therefore Contractible and Dilatable , your Authors opinion is , Of the Immortality of the Soul , l. 2. c. 10. That it begins within less compass at first in organizing the fitly prepared matter , and so bears it self on in the same tenour of work , till the body hath attained its full growth ; and that the Soul dilates it self in the dilating of the Body , and so possesses it through all the members thereof . Truly , Madam , as for the contraction and dilation of an immaterial Spirit , if I heard never so many arguments , I should hardly be able to conceive the possibility of it ; For in my opinion , dilating and contracting are motions and actions of Nature , which belong to natural material Creatures , and to none else ; for dilation and contraction cannot be without extension , but extension belongs to parts which an immaterial Spirit hath not : But suppose it be so , then the Soul must contract and dilate , extend and shrink together , and so grow less and bigger , according to the extension of the body ; and when the body dies , the soul , in my opinion , must contract to a very point ; and if one part of the body die before the other , the soul must by degrees withdraw out of those parts : also when a part of the body is cut off , the soul must needs contract , and grow less ; the like when a man is let blood . Which contracting of the soul , by your Authors leave , doth seem , to my imagination , just like the contracting of Hodmandod into her shell . Besides , if the soul be individable , and equally spread all over the body , then , to my opinion , she must necessarily be of a human shape ; and if the body be deformed , the soul must be deformed also ; and if the body be casually extended , as by taking Poyson into the body , the soul must be so too , as being individable and filling every part ; and if a man be born with six fingers or toes , the soul must be so too ; or if a dwarf , the soul must be a dwarf also ; and if he be born deaf and dumb , the soul must be so too . But if two Twins , as it may fall out , should be born united in one body , I would fain know then , whether they would have two souls , or but one ? As for example , if they should have but one body , and one stomack , liver , heart , spleen , lungs , bowels , and yet have four legs , four hands , and two heads : It seems , to my opinion , that then two Immaterial Souls must be joyned as into one ; neither do I know yet how this could well be , the monster having but one body , nor how that Immaterial Soul can be divided , being inseparably double , when the body dies . But , Madam , all this I speak of the Natural Soul of Man , not of the Divine Soul , which is not subject to natural imperfections , and corporeal errors , being not made by Nature , but a supernatural and divine gift of the Omnipotent God , who surely will not give any thing that is not perfect . Wherefore it is not probable , this Divine Soul , being not subject to Nature , should be an architect of the body , as having an higher and more divine imployment , viz. to fix her self on her Creator , and being indued with supernatural faculties , and residing in the body in a supernatural manner ; all which I leave to the Church : for I should be loth to affirm any thing contrary to their Doctrine , or the Information of the holy Scripture , as grounding my belief onely upon the sacred Word of God , and its true Interpretation made by the Orthodox Church ; but not upon the opinions of particular persons : for particular mens opinions are not authentical , being so different and various , as a man would be puzled which to adhere to . Thus , Madam , I avoid , as much as ever I can , not to mix Divinity with Natural Philosophy ; for I consider , that such a mixture would breed more confusion in the Church , then do any good to either ; witness the doctrine of the Soul of Man , whereof are so many different opinions : The onely cause , in my opinion , is , that men do not conceive the difference between the Divine , and Natural material Soul of Man , making them both as one , and mixing or confounding their faculties and proprieties , which yet are quite different ; thus they make a Hodg-podg , Bisk or Olio of both ; proving Divinity by Nature , and Faith by Reason ; and bringing Arguments for Articles of Faith , and sacred Mysteries out of Natural Arts and Sciences ; whereas yet Faith and Reason are two contrary things , and cannot consist together ; according to the Proverb , Where Reason ends , Faith begins . Neither is it possible that Divinity can be proved by Mathematical Demonstrations ; for if Nature be not able to do it , much less is Art : Wherefore it is inconvenient to mix supernatural Spirits with Air , Fire , Light , Heat , Cold , &c. and to apply corporeal actions and qualities to them ; and the Divine Soul , with the Brain , Blood , Flesh , Animal Spirits , Muscles , Nerves , Bones , &c. of Man ; all which makes a confusion betwixt the Mind or Natural Soul of Man , and the Supernatural and Divine Soul inspired into him by God ; for both their faculties and proprieties are different , and so are their effects , as proceeding from so different causes . And therefore , Madam , as for Divinity , I pray devoutly , and believe without disputing ; but as for Natural Philosophy , I reason freely , and argue without believing , or adhering to any ones particular opinion , which I think is the best and safest way to choose for ,

YOur Author in the continuation of his discourse concerning the Immaterial Soul of Man , demonstrating , that her seat is not bound up in a certain place of the body , but that she pervades all the body and every part thereof , takes , amongst the rest , an argument from Passions and Sympathies : Moreover , says he , Passions and Sympathies , in my judgment , are more easily to be resolved into this hypothesis of the Soul 's pervading Immort . of the Soul . Book 2. c. 10. the whole Body , then in restraining its essential presence to one part thereof . — But it is evident that they arise in us against both our will and appetite ; For who would bear the tortures of fears and jelousies , if he could avoid it ? Concerning Passions , Madam , I have given my opinion at large in my Book of Philosophy , and am of your Authors mind , that Passions are made in the Heart , but not by an Immaterial spirit , but by the Rational soul which is material ; and there is no doubt , but that many Passions , as Fear , Jealousie , &c. arise against our will and appetite ; for so may forreign Nations invade any Kingdom without the will or desire of the Inhabitants , and yet they are corporeal men : The same may be said of Passions ; and several parts of matter may invade each other , whereof one may be afraid of the other , yet all this is but according as corporeal matter moves , either Generally , or Particularly : Generally , that is , when many parts of Matter unite or joyn together , having the like appetites , wills , designs ; as we may observe , that there are general agreements amongst several parts , in Plagues , as well as Wars , which Plagues are not onely amongst Men , but amongst Beasts ; and sometimes but in one sort of animals , as a general Rot amongst Sheep , a general Mange amongst Dogs , a general Farcy amongst Horses , a general Plague amongst Men ; all which could not be without a general Infection , one part infecting another , or rather one part imitating the motions of the other , that is next adjoyning to it ; for such infections come by the neer adhesion of parts , as is observable , which immaterial and individable natural Spirits could not effect ; that is , to make such a general infection in so many several parts of so many several Creatures , to the Creatures dissolution : Also there will be several Invasions at one time , as Plague , and War , amongst neighbouring and adjoining Creatures or Parts . But this is to be observed , That the sensitive corporeal motions make all diseases , and not the Rational , although the Rational are many times the occasion , that the sensitive do move into such or such a disease ; for all those that are sick by conceit , their sicknesses are caused by the rational corporeal motions . But being loth to make tedious repetitions hereof , having discoursed of diseases and passions in my mentioned Book of Philosophy , I will refer you thither , and rest ,

COncerning Dimness of Sight , which your Author will have to proceed from the deficiency of the Animal Immort . of the Soul . Book 2. 6b . 8. Spirits , My meaning in short is , That when sight is dim , though the sensitive organs are perfect , this dimness is caused by the alteration onely of the sensitive motions in the organs , not moving to the nature of sight . And so is made Deafness , Dumbness , Lameness , and the like , as also Weariness ; for the Relaxation of strength in several parts , is onely an alteration of such sorts of motions which make the nerves strong ; and if a man be more dull at one time , then at another , it is that there are not so many changes of motions , nor so quick motions at that time , as at another ; for Nature may use more or less force as she pleases : Also she can and doth often use opposite actions , and often sympathetical and agreeable actions , as she pleases ; for Nature having a free power to move , may move as she will ; but being wise , she moves as she thinks best , either in her separating or uniting motions , for continuance , as well as for variety . But if , according to your Author , the Immaterial Soul should determinate matter in motion , it would , in my opinion , make a confusion ; for the motions of the Matter would often oppose and cross the motions of the Immaterial Soul , and so they would disagree , as a King and his Subjects , ( except God had given the Soul an absolute power of command , and restrained matter to an irrisistible and necessitated obedience ; which , in my opinion , is not probable : ) By which disagreement , Nature , and all that is in Nature , would have been quite ruined at this time ; for no kinds , sorts , or particulars , would keep any distinction , if Matter did not govern it self , and if all the parts did not know their own affairs , abilities , offices , and functions : Besides , it would , to my thinking , take up a great deal of time , to receive commands in every several action , at least so much , that for example , a man could not have so many several thoughts in so short a time , as he hath . But concerning the Animal Spirits , which your Author calls the Instruments , Organs and Engines of the Incorporeal Soul ; I would fain know , whether they have no motion but what comes from the Soul , or whether they have their own motion of themselves ? If the first , then the Soul must , in my opinion , be like a Deity , and have a divine Power , to give and impart Motion ; if the second , then the spirits being material , it follows that Matter hath motion of it self , or is self-moving ; But if the Immaterial natural Soul can transfer her gifts upon corporeal matter , then it must give numerous sorts of motions , with all their degrees ; as also the faculty of figuring , or moving figuratively in all corporeal Matter : Which power , in my judgment , is too much for a Creature to give . If you say , the Immaterial Soul hath this power from God ; I answer , Matter may have the same ; and I cannot imagine why God should make an Immaterial Spirit to be the Proxy or Vice-gerent of his Power , or the Quarter-master General of his Divine Providence , as your Author is pleased to style it , when Immort . of the Soul . Book 3. c. 13. he is able to effect it without any Under-Officers , and in a more easie and compendious way , as to impart immediately such self-moving power to Natural Matter , which man attributes to an Incorporeal Spirit . But to conclude , if the Animal Spirits be the Instruments of the Incorporeal Soul , then the Spirits of Wine are more powerfull then the Animal Spirits , nay , then the Immaterial Soul her self ; for they can put them and all their actions quite out of order : the same may be done by other material things , Vegetables , Minerals , and the like . And so leaving this discourse to your better consideration , I take my leave for this time , and rest ,

TOuching the State or Condition of the Supernatural and Divine Soul , both in , and after this life , I must crave your excuse that I can give no account of it ; for I dare affirm nothing ; not onely that I am no professed Divine , and think it unfit to take any thing upon me that belongs not to me , but also that I am unwilling to mingle Divinity and Natural Philosophy together , to the great disadvantage and prejudice of either ; for if each one did contain himself within the circle of his own Profession , and no body did pretend to be a Divine Philosopher , many absurdities , confusions , contentions , and the like , would be avoided , which now disturb both Church and Schools , and will in time cause their utter ruine and destruction ; For what is Supernatural , cannot naturally be known by any natural Creature ; neither can any supernatural Creature , but the Infinite and Eternal God , know thorowly everything that is in Nature , she being the Infinite servant of the Infinite God , whom no finite Creature , of what degree soever , whether natural or supernatural , can conceive ; for if no Angel nor Devil can know our thoughts , much less will they know Infinite Nature ; nay , one finite supernatural Creature cannot , in my opinion , know perfectly another supernatural Creature , but God alone , who is all-knowing : And therefore all what is said of supernatural Spirits , I believe , so far as the Scripture makes mention of them ; further I dare not presume to go ; the like of the supernatural or divine Soul : for all that I have writ hitherto to you of the Soul , concerns the natural Soul of Man , which is material , and not the supernatural or divine Soul ; neither do I contradict any thing concerning this divine soul , but I am onely against those opinions , which make the natural soul of man an immaterial natural spirit , and confound supernatural Creatures with natural , believing those spirits to be as well natural Creatures and parts of Nature , as material and corporeal beings are ; when as there is great difference betwixt them , and nothing in Nature to be found , but what is corporeal . Upon this account I take all their relations of Daemons , of the Genii , and of the Souls after the departure from humane Bodies , their Vehicles , Shapes , Habitations , Converses , Conferences , Entertainments , Exercises , Pleasures , Pastimes , Governments , Orders , Laws , Magistrates , Officers , Executioners , Punishments , and the like , rather for Poetical Fictions , then Rational Probabilities ; containing more Fancy , then Truth and Reason , whether they concern the divine or natural Soul : for as for the divine Soul , the Scripture makes no other mention of it , but that immediately after her departure out of this natural life , she goeth either to Heaven or Hell , either to enjoy Reward , or to suffer Punishment , according to man's actions in this life . But as for the Natural Soul , she being material , has no need of any Vehicles , neither is natural death any thing else but an alteration of the rational and sensitive motions , which from the dissolution of one figure go to the formation or production of another . Thus the natural soul is not like a Traveller , going out of one body into another , neither is air her lodging ; for certainly , if the natural humane soul should travel through the airy regions , she would at last grow weary , it being so great a journey , except she did meet with the soul of a Horse , and so ease her self with riding on Horseback . Neither can I believe Souls or Daemons in the Air have any Common-wealth , Magistrates , Officers and Executioners in their airy Kingdom ; for wheresoever are Governments , Magistrates and Executioners , there are also Offences , and where there is power to offend , as well as to obey , there may and will be sometimes Rebellions and Civil Wars ; for there being different forts of Spirits , it is impossible they should all fo well agree , especially the good and evil Genii , which certainly will fight more valiantly then Hector and Achilles , nay , the Spirits of one sort would have more Civil Wars then ever the Romans had ; and if the Soul of Caesar and Pompey should meet , there would be a cruel fight between those two Heroical souls ; the like between Augustus's and Antonius's Soul . But , Madam , all these , as I said , I take for fancies proceeding from the Religion of the Gentiles , not fit for Christians to embrace for any truth ; for if we should , we might at last , by avoiding to be Atheists , become Pagans , and so leap out of the Frying-pan into the Fire , as turning from Divine Faith to Poetical Fancy ; and if Ovid should revive again , he would , perhaps , be the chief head or pillar of the Church . By this you may plainly see , Madam , that I am no Platonick ; for this opinion is dangerous , especially for married Women , by reason the conversation of the Souls may be a great temptation , and a means to bring Platonick Lovers to a neerer acquaintance , not allowable by the Laws of Marriage , although by the sympathy of the Souls . But I conclude , and desire you , not to interpret amiss this my discourse , as if I had been too invective against Poetical Fancies ; for that I am a great lover of them , my Poetical Works will witness ; onely I think it not fit to bring Fancies into Religion : Wherefore what I have writ now to you , is rather to express my zeal for God and his true Worship , then to prejudice any body ; and if you be of that same Opinion , as above mentioned , I wish my Letter may convert you , and so I should not account my labour lost , but judg my self happy , that any good could proceed to the advancement of your Soul , from ,

I Sent you word in my last , I would not meddle with writing any thing of the Divine Soul of Man , by reason it belongs to Faith and Religion , and not to Natural Philosophy ; but since you desire my opinion concerning the Immortality of the Divine Soul , I cannot but answer you plainly , that first I did wonder much you made question of that , whose truth , in my opinion , is so clear , as hardly any rational man will make a doubt of it ; for I think there is almost no Christian in the world , but believes the Immortality of the Soul , no not Christians onely , but Mahometans and Jews : But I left to wonder at you , when I saw Wise and Learned Men , and great Divines , take so much pains as to write whole Volumes , and bring so many arguments to prove the Immortality of the Soul ; for this was a greater Miracle to me , then if Nature had shewed me some of her secret and hidden effects , or if I had seen an Immaterial Spirit . Certainly , Madam , it seems as strange to me to prove the Immortality of the Soul , as to convert Atheists ; for it impossible , almost , that any Atheist should be found in the World : For what Man would be so senceless as to deny a God ? Wherefore to prove either a God , or the Immortality of the Soul , is to make a man doubt of either : for as Physicians and Surgeons apply strengthening Medicines onely to those parts of the body which they suppose the weakest , so it is with proofs and arguments , those being for the most part used in such subjects , the truth of which is most questionable . But in things Divine , Disputes do rather weaken Faith , then prove Truth , and breed several strange opinions ; for Man being naturally ambitious , and endeavouring to excel each other , will not content himself with what God has been pleased to reveal in his holy Word ; but invents and adds something of his own ; and hence arise so many monstrous expressions and opinions , that a simple man is puzzled , not knowing which to adhere to ; which is the cause of so many schismes , sects , and divisions in Religion : Hence it comes also , that some pretend to know the very nature and essence of God , his divine Counsels , all his Actions , Designs , Rules , Decrees , Power , Attributes , nay , his Motions , Affections , and Passions , as if the Omnipotent Infinite God were of a humane shape ; so that there are already more divisions then Religions , which disturb the peace and quiet both of mind and body ; when as the ground of our belief consists but in some few and short Articles , which clearly explained , and the moral part of Divinity well pressed upon the People , would do more good , then unnecessary and tedious disputes , which rather confound Religion , then advance it : but if man had a mind to shew Learning , and exercise his Wit , certainly there are other subjects , wherein he can do it with more profit , and less danger , then by proving Christian Religion by Natural Philosophy , which is the way to destroy them both . I could wish , Madam , that every one would but observe the Command of Christ , and give to God what is Gods , and to Caesar what is Caesars , and so distinguish what belongs to the actions of Nature , and what to the actions of Religion ; for it appears to my Reason , that God hath given Nature , his eternal Servant , a peculiar freedom of working and acting , as a self-moving Power from Eternity ; but when the Omnipotent God acts , he acts supernaturally , as beyong Nature ; of which devine actions none but the holy Church , as one united body , mind and soul , should discourse , and declare the truth of them , according to the Revelation made by God in his holy Word , to her Flock the Laity , not suffering any one single person , of what profession or degree soever , indifferently to comment , interpret , explain , and declare the meaning or sense of the Scripture after his own fancy . And as for Nature's actions , let those whom Nature hath indued with such a proportion of Reason , as is able to search into the hidden causes of natural effects , contemplate freely , without any restraint or consinement ; for Nature acts freely , and so may natural Creatures , and amongst the rest Man , in things which are purely natural ; but as for things supernatural , man cannot act freely , by reason they are beyond his sphere of conception and understanding , so as he is forced to set aside Reason , and onely to work by Faith . And thus , Madam , you see the cause why I cannot give you a full description of the Divine Soul of Man , as I mentioned already in my last , but that I do onely send you my opinion of the natural soul , which I call the rational soul ; not that I dare say , the supernatural soul is without natural reason , but natural reason is not the divine soul ; neither can natural reason , without Faith , advance the divine soul to Heaven , or beget a pious zeal , without divine and supernatural Grace : Wherefore Reason , or the rational Soul is onely the Soul of Nature , which being material , is dividable , and so becomes numerous in particular natural Creatures ; like as the sensitive life being also material and dividable , becomes numerous , as being in every Creature , and in every part of every Creature ; for as there is life in every Creature , so there is also a soul in every Creature ; nay , not onely in every Creature , but in every particle of every Creature , by reason every Creature is made of rational and sensitive Matter ; and as all Creatures or parts of Nature are but one infinite body of Nature , so all their particular souls and lives make but one infinite soul and life of Nature ; and this natural soul hath onely natural actions , not supernatural ; nor has the supernatural soul natural actions ; for although they subsist both together in one body , yet each works without disturbance to the other ; and both are Immortal ; for of the supernatural soul there is no question , and of the natural soul , I have said before , that nothing is perishable or subject to annihilation in nature , and so no death , but what is called by the name of death , is onely an alteration of the corporeal natural motions of such a figure to another figure ; and therefore as it is impossible , that one part of Matter should perish in Nature , so is it impossible , that the natural or rational soul can perish , being material : The natural humane soul may alter , so as not to move in an animal way , or not to have animal motions , but this doth not prove her destruction or annihilation , but onely a change of the animal figure and its motions , all remaining still in Nature . Thus my Faith of the Divine , and my opinion of the Natural Soul , is , that they are both Immortal ; as for the immediate actions of the Divine Soul , I leave you to the Church , which are the Ministers of God , and the faithful dispensers of the sacred mysteries of the Gospel , the true Expounders of the Word of God , Reformers of mens lives , and Tutors of the Ignorant , to whom I submit my self in all that belongs to the salvation of my Soul , and the regulating of the actions of my life , to the honour and glory of God . And I hope they will not take any offence at the maintaining and publishing my opinions concerning Nature and Natural effects , for they are as harmless , and as little prejudicial to them , as my designs ; for my onely and chief design is , and ever hath been to understand . Nature rightly , obey the Church exactly , Believe undoubtedly , Pray zealously , Live vertuously , and Wish earnestly , that both Church and Schools may increase and flourish in the sacred knowledge of the true Word of God , and that each one may live peaceable and happily in this world , die quietly , and rise blessedly and gloriously to everlasting Life and happiness : Which happiness I pray God also to confer upon your Ladiship ; Till then , I rest ,

I Will leave the Controversie of Free-Will and Necessity , Of the Immortality of the Soul . l. 1. c. 3. which your Author is discoursing of , to Divines to decide it , onely I say this , that Nature hath a natural Free-will and power of self-moving , and is not necessitated ; but yet that this Free-will proceeds from God , who hath given her both will and power to act freely . But as for the question , whether there be nothing Lib. 2. c. 2. in the Universe , but meer body ? I answer , My opinion is not , that there is nothing in the world but meer Body ; but that Nature is purely material or corporeal , and that there is no part of Nature , or natural Creature , which is not Matter , or Body , or made of Matter ; also , that there is not any thing else mixt with body , as a copartner in natural actions , which is distinct from Body or Matter ; nevertheless , there may be supernatural spiritual beings or substances in Nature , without any hinderance to Matter or corporeal Nature . The same I may say of the natural material , and the divine and supernatural Soul ; for though the divine Soul is in a natural body , and both their powers and actions be different , yet they cause no ruine or disturbance to each other , but do in many cases agree with each other , without incroachment upon each others powers or actions ; for God , as he is the God of all things , so the God of Order . Wherefore it is not probable , that created Immaterial or Incorporeal beings should order Corporeal Nature , no more then Corporeal Nature orders Immaterial or Incorporeal Creatures . Neither can , in my opinion , Incorporeal Creatures be clearly conceived by Corporeals , although they may really exist and subsist in Nature ; onely , as I said before , it is well to be considered , that there is difference betwixt being in Nature , and being a part of Nature ; for bodiless things , and so spiritual substances , although they may exist in Nature , yet they are not natural , nor parts of Nature , but supernatural , Nature being meerly corporeal , and Matter the ground of Nature ; and all that is not built upon this material ground , is nothing in Nature . But you will say , The divine Soul is a part of Man , and Man a part of Nature , wherefore the divine Soul must needs be a part of Nature . I answer , Not : For the divine Soul is not a part of Nature , but supernatural , as a supernatural Gift from God onely to Man , and to no other Creature : and although in this respect it may be called a part of Man , yet it is no natural or material part of Man ; neither doth this supernatural Gift disturb Nature or natural Matter , or natural Matter this supernatural Gist . And so leaving them both , I rest ,

IF you desire my opinion concerning Witches , whereof your Learned Author hath many Discourses and Stories : I will tell you really , that in my sense Antid. lib. 3. and reason , I do not believe any , except it be the witch of Endor , which the Scripture makes mention of ; for though I believe that there is a Devil , as the Word of God and the Church inform me , yet I am not of the opinion , that God should suffer him to have such a familiar conjunction , and make such contracts with Man , as to impower him to do mischief and hurt to others , or to foretell things to come , and the like ; for I believe that all things Immaterial , as Spirits , Angels , Devils , and the divine Soul of Man , are no parts of Nature , but Supernatural , Nature knowing of no Creature that belongs to her , but what is material ; and since incorporeal Creatures are no parts of Nature , they neither have natural actions , nor are they concerned as copartners or co-agents in the actions of Nature and natural Creatures ; but as their substances , so their actions are supernatural , and beyond our conceivement . As for Faires , I will not say , but there may be such Creatures in Nature , and have airy bodies , and be of a humane shape , and have humane actions , as I have described in my Book of Poems ; for there are many things in Nature , whereof Man hath no knowledg at all , and it would be a great folly for any one to deny what he doth not see , or to ascribe all the unusual effects in Nature to Immaterial Spirits ; for Nature is so full of variety , that she can and doth present sometimes such figures to our exterior senses , as are not familiar to us , so as we need not to take our refuge to Immaterial Spirits : nay , even those that are so much for Incorporeal Spirits , must confess , that they cannot be seen in their own natures , as being Invisible , and therefore have need to take vehicles of some grosser bodies to manifeft themselves to men : and if Spirits cannot appear without bodies , the neerest way is to ascribe such unusual effects or apparitions , as happen sometimes , rather to matter that is already corporeal , and not to go so far as to draw Immaterial Spirits to Natural actions , and to make those Spirits take vehicles fit for their purposes : for Nature takes sometimes delight in unusual Varieties . Concerning those stories which your Author relates In his discourse of Euthusiasm . esct . of the strange effects of Food received into a mans body , how they did work upon the Imagination , and change and transform the humors of those that did feed upon them , those , I say , seem very probable to me . As for example ; of a Wench who being struck into an Epilepsy , upon the seeing of a Malefactors Head cut off , was advised to drink Cats-blood ; which being done , she not long after degenerated into the nature and property of that Animal , cried and jump'd like a Cat , and hunted Mice with the same silence and watchfulness as they do . Then of a Man , being long fed with Swines-blood , which took a special pleasure in wallowing and tumbling himself in the mire . Also of a Girle , which being nourished up with Goats-milk , would skip like a Goat , and brouze on Trees as Goats use to do . And of a Man , who by eating the brains of a Bear , became of a Bear-like disposition . All these stories I believe to be true ; for naturally the motions of a Man may sometimes sympathize so much with the received food , as to make an alteration in his humour or disposition . But although it be natural , yet it is not regular , at least not usual , but proceeds from an irregular and unusual change of motions , like as the conception and generation of a Monster ; For if it were ordinary , then those which drink much of the blood of beasts , would also degenerate into a beastly nature , the contrary whereof is sufficiently known : Likewise those that drink much of Cows-milk , would change into their humors and natures . But certainly , some kinds of meats do not onely cause sickness , but madness , and strange Imaginations ; all which unnatural or unusual accidents are caused by Matter 's irregular motions ; Whereof I have declared my opinion in other places ; and so I rest ,

YOu will have my opinion of the Book that treats of the Pre-existence of Souls , and the Key that unlocks the Divine Providence ; but I have told you heretofore , that there are so many different opinions concerning the Soul , as I do not know which to embrace , for the multiplicity confounds my choice : and the cause of these various opinions , in my simple judgment , is , that most men make no difference between the Divine , and Natural Soul . As for the Natural Soul , humane sense and reason may perceive , that it consists of Matter , as being Material ; but as for the Divine Soul , being not material , no humane sense and reason is able naturally to conceive it ; for there cannot possibly be so much as an Idea of a natural nothing , or an immaterial being , neither can sense and reason naturally conceive the Creation of an Immaterial substance ; for as the Creation of material Creatures , as of this World , belongs to Faith , and not to Reason , so doth also the Creation of Immaterial substances , as Spirits ; nay , it is more difficult to understand a Natural Nothing to be made out of nothing , then a Natural Something out of nothing . And as for the Progress of Immaterial Souls , which the same Author mentions , I cannot conceive how No-thing can make a Progress , and therefore I suppose , it is an Improper , or Metaphorical expression . The truth is , what is Immaterial , belongs not to a Natural knowledg or understanding , but is Supernatural , and goes beyond a natural reach or capacity . Concerning the Key of Divine Providence , I believe God did never give or lend it to any man ; for surely , God , who is infinitely Wise , would never intrust so frail and foolish a Creature as Man , with it , as to let him know his secret Counsels , Acts , and Decrees . But setting aside Pride and Presumption , Sense and Reason may easily perceive , that Man , though counted the best of Creatures , is not made with such infinite Excellence , as to pierce into the least secrets of God ; Wherefore I am in a maze when I hear of such men , which pretend to know so much , as if they had plundered the Celestial Cabinet of the Omnipotent God ; for certainly , had they done it , they could not pretend to more knowledg then they do . But I , Madam , confess my Ignorance , as having neither divine Inspirations , nor extraordinary Visions , nor any divine or humane learning , but what Nature has been pleased to bestow upon me : Yet in all this Ignorance , I know that I am , and ought to be ,

SInce in my former Letters I have discoursed of Immaterial Spirits , and declared my meaning , that I do not believe them to be natural Creatures , or parts of Nature ; you are of opinion , as if I did contradict my self , by reason that in the first Edition of my Book called Philosophical Opinions , I name the rational and sensitive Matter , rational and sensitive Spirits . To which I answer , first , That when I did write my first Conceptions in Natural Philosophy , I was not so experienced , nor had I those observations which I have had since ; Neither did I give those first Conceptions time to digest , and come to a maturity or perfect growth , but forced them forth as soon as conceived , and this made the first publishing of them so full of Imperfections , which I am much sorry for ; But since that time , I have not onely reviewed , but corrected and altered them in several places , so that the last Impression of my Philosophical Opinions , you will find more perfect and exact then the former . Next , I pray you to take notice , Madam , that in the mentioned first Edition , by the word Spirits , I meant Material , not Immaterial Spirits ; for observing , that Learned Men do discourse much of Animal Spirits , which are Material , and that also high extracts in Chymistry are called Spirits ; I used that word purposely , thinking it most proper and convenient to express my sense and meaning of that degree of matter which I call rational and sensitive . But considering again , that my opinions , being new , would be subject to misapprehensions and mis-interpretations ; to prevent those , I thought it fitter to leave out the word Spirits in the second , as also in the last Edition of my named Book of Philosophy , lest my Readers should think I meant Immaterial Spirits ; for I confess really , that I never understood , nor cannot as yet apprehend Immaterial Spirits ; for though I believe the Scripture , and the Church , that there are Spirits , and do not doubt the existency of them , yet I cannot conceive the nature of Immaterial Spirits , and what they are ; Wherefore I do onely treat of natural material substances , and not of incorporeal ; also my discourse is of the Infinite servant of the Infinite God , which servant is corporeal or material Nature : God is onely to be admired , adored , and worshipped ; but not ungloriously to be discoursed of ; Which Omnipotent God , I pray of his Infinite Mercy to give me Faith to believe in him , and not to let presumption prevail with me so , as to liken vain and idle conceptions to that Incomprehensible Deity . These , Madam , are my humble Prayers to God ; and my request to you is , that I may continue the same in your love and affection , which I have been hitherto ; so shall I live content , and rest ,

SECT. III.
I. MADAM ,

I Have discharged my duty thus far , that in obedience to your commands , I have given you my answers to the opinions of three of those famous and learned Authors you sent me , viz. Hobbes , Des Cartes , and More , and explained my own opinions by examining theirs ; My onely task shall be now to proceed in the same manner with that famous Philosopher and Chymist , Van Helmont ; But him I find more difficult to be understood then any of the forementioned , not onely by reason of the Art of Chymistry , which I confess my self not versed in , but especially , that he has such strange terms and unusual expressions as may puzle any body to apprehend the sense and meaning of them : Wherefore , if you receive not that full satisfaction you expect from me , in examining his opinions and arguments , I beg your pardon before hand , and desire you to remember , that I sent you word in the beginning , I did undertake this work more out of desire to clear my own opinions , then a quarrelsome humor to contradict others ; which if I do but obtain , I have my aim . And so to the business : When as your Author discourses of the causes and beginnings of Natural things , he is pleased to say , That Souls and Lives , as they know no Degrees , so they know no Parts ; which Van Helm . in his Book intituled , Physick Refined , ch. 4. of the Causes and begining of natural things . opinion is very different from mine : For although I confess , that there is but one kind of Life , and one kind of Soul in Nature , which is the sensitive Life , and the rational Soul , both consisting not onely of Matter , but of one kind of Matter , to wit , Animate ; nevertheless they are of different degrees , the matter of the rational Soul being more agil , subtil and active , then the matter of the sensitive Life ; which is the reason that the rational can act in its own substance or degree of matter , and make figures in it self , and its own parts ; when as the sensitive , being of somewhat a grosser degree then the rational , and not so subtil and active , is confined to work with and upon the Inanimate matter . But mistake me not , Madam , for I make onely a difference of the degrees of Subtilty , Activity , Agility , Purity , betwixt rational and sensitive Matter ; but as for the rational Matter it self , it has no degrees of Purity , Subtilty and Activity in its own Nature or Parts , but is always one and the same in its substance in all Creatures , and so is the sensitive . You will ask me , How comes then the difference of so many Parts and Creatures in Nature , if there be no degrees of Purity , Activity , and Subtilty in the substance of the rational , and in the substance of the sensitive Matter ? As for example : if there were no such degrees of the Parts of rational Matter amongst themselves , as also of the Parts of the sensitive , there would be no difference betwixt Animals , Vegetables , Minerals , and Elements , but all Creatures would be alike without distinction , and have the same manner of sense and reason , life and knowledg . I answer , That although each sort or degree of animate Matter , rational as well as sensitive , has in it self or its own substance no degrees of purity , rarity , and subtilty , but is one and the same in its nature or essence ; nevertheless , each has degrees of quantity , or parts , which degrees of quantity do make the onely difference betwixt the several creatures or parts of Nature , as well in their general , as particular kinds ; for both the rational and sensitive matter being corporeal , and so dividable into parts , some creatures do partake more , some less of them , which makes them to have more or less , and so different sense and reason , each according to the nature of its kind : Nay this difference of the degrees of quantity or parts in the substance of the rational and sensitive Matter , makes also the difference betwixt particulars in every sort of Creatures , as for example , between several particular Men : But as I said , the nature or essence of the sensitive and rational Matter is the same in all ; for the difference consists not in the Nature of Matter , but onely in the degrees of quantity , and parts of Matter , and in the various and different actions or motions of this same Matter . And thus Matter being dividable , there are numerous lives and souls in Nature , according to the variousness of her several Parts and Creatures . Next your Author , mentioning the Causes and Principles of natural Bodies , assigns two first or chief beginnings and corporeal causes of every Creature , to wit , the Element of Water , and the Ferment or Leaven ; which Ferment he calls a formal created being ; neither a substance , nor an accident , but a neutral thing . Truly , Madam , my reason is not able to conceive this neutral Being ; for it must either be something or nothing in Nature : and if he makes it any thing betwixt both , it is a strange Monster , and will produce monstrous effects : and as for Water , if he doth make it a Principle of Natural things , I see no reason why he excludes the rest of the Elements : But , in my opinion , Water , and the rest of the Elements , are but effects of Nature , as other Creatures are , and so cannot be prime causes . The like the Ferment , which , to my sense and reason , is nothing else , but a natural effect of natural matter . Concerning his opinion , That Causes and Beginnings are all one , or that there is but little difference betwixt them , I do readily subscribe unto it ; but when he speaks of those things , which are produced without life , my reason cannot find out , what , or where they should be ; for certainly , in Nature they are not , Nature being Life and Soul her self , and all her parts being enlivened and soulified , so that there can be no generation or natural production without Life . Neither is my sense and reason capable to understand his meaning , when he says , That the Seeds of things , and the Spirits , as the Dispensers thereof , are divided from the Material Cause : For I do see no difference betwixt the Seed , and the material Cause , but they are all one thing , it being undeniable , that the seed is the matter of that which is produced . But your Author was pleased to say heretofore , that there are but two beginnings or causes of natural things , and now he makes so many more ; for , says he , Of Efficient and Seminal Causes , some are efficiently effecting , and others effectively effecting : which nice distinctions , in my opinion , do but make a confusion in natural knowledg , setting a mans brain on the rack ; for who is able to conceive all those Chymaeras and Fancies of the Archeus , Ferment , various Ideas , Blas , Gas , and many more , which are neither something nor no-thing in Nature , but betwixt both , except a man have the same Fancies , Visions and Dreams , your Author had ? Nature is easie to be understood , and without any difficulty , so as we stand in no need to frame so many strange names , able to fright any body . Neither do natural bodies know many prime causes and beginnings , but there is but one onely chief and prime cause from which all effects and varieties proceed , which cause is corporeal Nature , or natural self-moving Matter , which forms and produces all natural things ; and all the variety and difference of natural Creatures arises from her various actions , which are the various motions in Nature ; some whereof are Regular , some Irregular : I mean Irregular , as to particular Creatures , not as to Nature her self , for Nature cannot be disturbed or discomposed , or else all would run into confusion ; Wherefore Irregularities do onely concern particular Creatures , not Infinite Nature ; and the Irregularities of some parts may cause the Irregularities of other Parts , as the Regularities of some parts do cause the Regularities of others : And thus according as Regularities and Irregularities have power , they cause either Peace or War , Sickness or Health , Delight and Pleasure , or Grief and Pain , Life or Death , to particular Creatures or parts of Nature ; but all these various actions are but various Effects , and not prime Causes ; which is well to be observed , lest we confound Causes with Effects . And so leaving this discourse for the present , I rest ,

MADAM , Your Faithful Friend and Servant .
II. MADAM ,

IT is no wonder , your Author has so many odd and strange opinions in Philosophy , since they do not onely proceed from strange Visions , Apparitions , and Dreams , but are built upon so strange grounds and principles as Ideas , Archeus , Gas , Blas , Ferment , and the like , the names of which sound so harsh and terrifying , as they might put any body easily into a fright , like so many Hobgoblins or Immaterial spirits ; but the best is , they can do no great harm , except it be to trouble the brains of them , that love to maintain those opinions ; for though they are thought to be powerful beings , yet being not corporeal substances , I cannot imagine wherein their power should consist ; for Nothing In his ch. called The Fiction of Elementary Complexions and Mixtures . can do nothing . But to mention each apart ; first his Archeus he calls the Spirit of Life ; a vital Gas or Light ; the Balsam preserving from Corruption ; the Vulcan or In the ch. Of the Birth and Original of Forms . Smith of Generation ; the stirrer up , and inward director of Generation ; an Air ; a skiey or airy Spirit ; cloathing himself presently with a bodily cloathing , in things In the ch. Of the Ideas of Diseases . See his ch. called The Seat of Diseases in the Soul is confirmed . soulified , walking through all the dens and retiring places of the seed , and transforming the matter according to the perfect act of its own Image , remaining the president and overseer or inward ruler of his bounds even till death ; the Principle of Life : the Inn of Life , the onely immediate Ch. Of Archeal Diseases . Witness , Executor , and Instrument of Life ; the Prince Ch. called The Subject of inhering of Diseases is in the point of life , &c. and Center of Life ; the Ruler of the Stern ; the Keeper of Life , and promoter of Transmutations ; the Porter of the Soul ; a Fountainous being ; a Flint . These , and many more names your Author attributes to his Archeus , but what properly it is , and what its Nature and its peculiar office , I am not able to conceive . In the next place , Gas and Blas are to your Author also true Principles of Natural things ; for Gas a a In the ch. Of the Gas of the Water . is the Vapour into which Water is dissolved by Cold , but yet it is a far more fine and subtil thing then Vapour ; which he demonstrates by the Art of Chymistry . This Gas in another place he calls b b In the ch. Of the Fiction of Elementary Complexions and Mixtures . a Wild Spirit , or Breath , unknown hitherto , which can neither be constrained by Vessels , nor reduced into a visible body ; in some things it is nothing but Water ; as for example in Salt , in Fruits , and the like . But Blas c c In the ch. Of the Blas of Meteors . proceeds from the local and alterative motion of the Stars , and is the general beginning of motion , producing heat and cold , and that especially with the changing of the Winds . There is also Blas d d In the ch. Of the unknown action of Government . in all sublunary things ; witness Amulets or preserving Pomanders , whereby they do constrain objects to obey them ; Which Incorporeal Blas of Government acts without a Corporeal Efflux , even as the Moon makes the Sea to swell ; but the fleshly generation e e In the ch. Of the Blas of Man . hath a Blas of its own , and it is twofold , one which existeth by a natural Motion , the other voluntary , which existeth as a mover to it self by an Internal Willing . There is also a Blas of the Heart , which is the fuel of the Vital Spirit , and consequently of its heat . The Ferment f f Of the Causes and beginnings of Natural things . he describes to be A true Principle or Original beginning of things , to wit , a Formal Created being , which is neither a substance , nor an accident , but a Neutral being , framed from the beginning of the World in the places of its own Monarchy , in the manner of Light , Fire , the magnal or sheath of the Air , Forms , &c. that it may prepare , stir up , and go before the Seeds . Lastly , his Ideas are Certain formal seminal Lights , g g Of the Ideas of Diseases . mutually piercing each other without the adultery of Union ; For , says he , although at first , that , which is imagined , is nothing , but a meer being of reason , yet it doth not remain such ; for truely the Fancy is a sealifying vertue , and in this respect is called Imaginative , because it forms the Images of Likenesses , or Ideas of things conceived , and doth characterize them in its own Vital Spirit , and therefore that Idea is made a spiritual or seminal powerful being , to perform things of great moment . And those Ideas he makes various and numerous ; as Archeal Ideas , Ideas of Diseases , Sealifyiug Ideas , Piercing Ideas , Forreign and strange Ideas , Mad Ideas , Irrational and Incorrigible Ideas , Staggering Ideas , and a hundred others : the like of Gas , Blas , and the rest . Thus , Madam , I have made a rehearsal of your Authors strange , and hitherto unknown , Principles ( as his Confession is ) of Natural things , which , to my sense and reason , are so obscure , intricate and perplex , as is almost impossible exactly to conceive them ; when as Principles ought to be easie , plain , and without any difficulty to be understood ; Wherefore what with his Spirits , meer-beings , non-beings , and neutralbeings , he troubles Nature , and puzles the brains of his Readers so , that , I think , if all men were of his opinion , or did follow the way of his Philosophy , Nature would desire God she might be annihilated : Onely , of all other , she doth not fear his Non-beings , for they are the weakest of all , and can do her the least hurt , as not being able to obstruct real and corporeal actions of Nature ; for Nature is a corporeal substance , and without a substance Motion cannot be , and without Motion opposition cannot be made , nor any action in Nature , whether Prints , Seals , Stamps , Productions , Generations , Thoughts , Conceptions , Imaginations , Passions , Appetites , or the like : and if motions cannot be without substance ; then all Creatures , their properties , faculties , natures ; &c , being made by corporeal motions , cannot be Non-beings , no nor anything else that is in Nature ; for non-beings are not in the number of Natural things , Nature containing nothing within her , but what is substantially , really , and corporeally existent . But your Authors a a Of the Magnetick cure of wounds . Ideal Entity , ( whereof he is speaking in another place of his Works , ) which performs all the Works of Nature , seems to me , as if it were the Jack of all Offices , or like the Jack in a Clock , that makes every Wheel move ; for it hath an admirable power to put off and on Corporeality and Incorporeality , and to make it self Something and Nothing as often as it has occasion ; but if this Proteus have such power , it may well be named the Magick of Nature . Your Author saith , it is not the Devil , nor any effect thereof : but certainly , in my opinion , according to its description , and the effects laid to its performance , it must be more then the Devil ; wherefore , in my Reason , I cannot conceive it , neither am I able to understand his Phantastick Activity , Fancy of Forms , the Souls acting by an insensible way , and many more such like expressions . But I conceive that all these can be nothing else but the several motions of the sensitive and rational matter , which is the Active , Ingenious , Distinguishing , Knowing , Wise and Understanding part of Infinite corporeal Nature ; and though Infinite Matter hath Infinite parts in general , yet there is a finiteness in every part considered by it self : not that I think a Part can really subsist single and by it self , but it is onely considered so in the manner of our Conception , by reason of the difference and variousness of natural Creatures : for these being different from each other in their figures , and not all alike , so that we can make a distinction betwixt them ; this difference and distinction causes us to conceive every part of a different figure by it self : but properly and according to the Truth of Nature , there is no part by it self subsisting ; for all parts are to be considered , not onely as parts of the whole , but as parts of other parts , all parts being joyned in Infinite Nature , and tied by an inseparable tie one way or other , although we do not altogether perceive it . But to return to Ideas : I had almost forgot to tell you , Madam , of another kind of Ideas , by your Author named , Bewitching or Inchanting Ideas , b b Of things Conceived , or Conceptions . which are for the most part found in Women , against which I cannot but take exception in the behalf of our Sex : For , says he , Women stamp Ideas on themselves , whereby they , no otherwise then Witches driven about with a malignant spirit of despair , are oftentimes governed or snatched away unto those things , which otherwise they would not , and do bewail unto us their own and unvoluntary Madness : These Ideas are hurtful to themselves , and do , as it were , Inchant , Infatuate , and weaken themselves ; for so ( as Plutarch witnesses ) a desire of death by hanging took hold of all the young Maids in the Island Chios . By this it appears , that your Author has never been in Love , or else he would have found , that Men have as well bewitching Ideas as Women , and that they are as hurtful to Men , as to Women . Neither can I be perswaded to believe , that men should not have as well Mad Ideas as Women ; for to mention no other example , some , ( I will not speak of your Author ) their Writings and strange Opinions in Philosophy do sufficiently witness it ; but whence those Ideas do proceed , whether from the Bride-bed of the Soul , or the Splene , your Author doth not declare . As for the young Maids in Chios , I must confess , it is a very strange example ; but I think there have been as many Men that have killed themselves , as Women , if not more : However , I hope , by the Grace of God , the young Maids in this Kingdom are better advised ; for if they should do the like , it would be a sad fate for all young Men. To conclude , Madam , all these rehearsed opinions of your Author , concerning the Grounds or Principles of Natural Philosophy , if you desire my Unfeigned Judgment , I can say no more , but that they shew more Fancy , then Reason and Truth , and so do many others ; and , perhaps , my opinions may be as far from Truth as his , although their Ground is Sense and Reason ; for there is no single Creature in Nature , that is able to know the perfectest Truth : but some opinions , to humane sense and reason , may have more probability then others , and every one thinks his to be most probable , according to his own fancy and imagination , and so I think of mine ; nevertheless , I leave them to the censure of those , that are endued with solid judgment and reason , and know how to discern betwixt things of fancy and reason , and amongst the rest , I submit them to the censure of your Ladiship , whose solid and wise Judgment is the rule of all the actions of ,

YOur Author relating how he dissents from the False Doctrine , as he terms it , of the Schools , concerning the Elements , and their Mixtures , Qualities , Temperaments , Discords , &c. in order to Diseases , In his Treatise called . A passive deceiving of the Schools of the Humourists . is pleased to say as follows : I have sufficiently demonstrated , that there are not four Elements in Nature , and by consequence , if there are onely three , that four cannot go together , or encounter ; and that the fruits which Antiquity hath believed to be mixt bodies , and those composed from a concurrence of four Elements , are materially of one onely Element ; also that those three Elements are naturally cold ; nor that native heat is any where in things , except from Light , Life , Motion , and an altering Blas : In like manner , that all actual moisture is of Water , but all virtual moisture from the property of the seeds : Likewise , that dryness is by it self in the Air and Earth , but in Fruits by reason of the Seeds and Coagulations ; and that there are not Contraries in Nature . To give you my opinion hereof , first I think it too great a presumption in any man , to feign himself so much above the rest , as to accuse all others of ignorance , and that none but he alone hath the true knowledg of all things as infallible and undeniable , and that so many Learned , Wise and Ingenious Men in so many ages have been blinded with errors ; for certainly , no particular Creature in Nature can have any exact or perfect knowledg of Natural things , and therefore opinions cannot be infallible truths , although they may seem probable ; for how is it possible that a single finite Creature should know the numberless varieties and hidden actions of Nature ? Wherefore your Author cannot say , that he hath demonstrated any thing , which could not be as much contradicted , and perhaps with more reason , then he hath brought proofs and demonstrations : And thus when he speaks of Elements , that there are not four in Nature , and that they cannot go together , or encounter , it may be his opinion ; but others have brought as many reasons to the contrary , and I think with more probability ; so as it is unnecessary to make a tedious discourse thereof , and therefore I 'le refer you to those that have treated of it more learnedly and solidly then I can do . But I perceive your Author is much for Art , and since he can make solid bodies liquid , and liquid bodies solid , he believes that all bodies are composed out of the Element of Water , and that Water therefore is the first Principle of all things ; when as Water , in my opinion , is but an Effect , as all other natural Creatures , and therefore cannot be a cause or principle of them . Concerning the Natural coldness of Water , Air , and Earth , it may be , or not be so , for any thing your Author can truly know ; but to my sense and reason , it seems probable that there are things naturally hot and moist , and hot and dry , as well as cold and moist , and cold and dry : But all these are but several effects produced by the several actions of Natural Matter , which Natural Matter is the onely Principle of all Natural Effects and Creatures whatever ; and this Principle , I am confident your Author can no more prove to be Water , then he can prove that Heat , Light , Life , Motion , and Blas , are not material . Concerning what he saith , That Native Heat is no where in things , except from Light , Life , Motion , and an altering Blas : I believe that motion of life makes not onely heat , but all effects whatsoever ; but this native heat is not produced onely from the motions of Particular lives in particular Creatures , but it is made by the motions of Natures life ; which life , in all probability , is the self-moving Matter , which no doubt , can and doth make Light and Blas without Heat , and Heat without Light or Blas ; Wherefore Light and Blas are not principles of native Heat , no more then native Heat is the principle of Light and Blas . Neither is Water the Principle of Actual moisture , nor the propriety of seeds the Principle of all Virtual moisture ; but self-moving Matter is the Principle of all , and makes both actual and virtual moisture , and there is no question but there are many sorts of moistures . As for Dryness , which he says , is by it self in the Air and Earth , and in Fruits by reason of the Seeds and Coagulations : I cannot conceive how any thing can be by it self in Nature , by reason there is nothing alone and single in Nature , but all are inseparable parts of one body : perchance , he means , it is naturally and essentially inherent in Air and Earth ; but neither can that be in my reason , because all Creatures and Effects of Nature are Intermixt , and there is as much dryness in other Creatures , as in Air and Earth . Lastly , as for his opinion , That there are no Contraries in Nature ; I believe not in the essence or nature of Matter ; but sense and reason inform us , that there are Contraries in Natures actions , which are Corporeal motions , which cause mixtures , qualities , degrees , discords , as also harmonious conjunctions and concords , compositions , divisions , and the like effects whatsoever . But though your Author seems to be an enemy to the mixtures of Elements , yet he makes such a mixture of Divinity , and natural Philosophy , that all his Philosophy is nothing but a meer Hotch-potch , spoiling one with the other . And so I will leave it to those that delight in it , resting ,

WAter , according to your Authors opinion , is frozen into Snow , Ice , or Hail , not by Cold , Ch. Of the Gas of Water . but by its own Gas . But since I am not able to conceive what his Gas is , being a term invented by himself , I will briefly declare my own opinion , which is , That Snow , Ice , and Hail , in my judgment , are made in the like manner , as Passions or Colours are made and raised in Man ; for a sad discourse , or a cruel object will make a Man pale and cold , and a fearful object , will make him tremble ; whereas a wanton and obscene discourse will make some red and hot . But yet these discourses and objects are onely external , occasional , and not immediate efficient causes of such alterations . Also when a Man eats or drinks any thing that is actually hot or cold , or enters into a cold or hot room , bath , or air , he becomes hot or cold by the actions of those external agents that work upon him , or rather whose motions the sensitive motions of his body do pattern out . The like for diseases ; for they may be caused either by hearing ill reports , or by taking either hurtful or superfluous food into the Body , or by Infections inwardly or outwardly , and many other ways . Likewise may Colours be made different ways ; And so may Snow , Ice , and Hail ; for all loose , rare , and porous Bodies are more apt to alter and change then close , solid , and dense bodies ; and not onely to change from what they are , but to rechange to what they were . But , Madam , many studious persons study Nature more in her own substance , then in her various actions , which is the cause they arrive to no knowledg of Natures Works ; for the same parts of Matter may act or work several ways : Like as a Man , or other animal creature , may put one part of his body into various and several postures , and move it many different ways . Your Author may say , that although several Creatures may be changed to our sight or perception , yet they are not really changed in Nature . I answer , Their Principle , which is a natural matter , of which all Creatures are made , cannot be changed , because it is one , simple , and unalterable in its Nature ; but the figures of several Creatures are changed continually by the various motions of this matter ; not from being matter , but onely from such or such a figure into another ; and those figures which do change , in their room are others produced to keep up the certain kinds of Creatures by a continual successive alteration . And as there are changes of parts , so there are also mixtures of several parts , figures and motions in one and the same Matter ; for there are not different kinds in the nature of Matter : But , although Matter is of several degrees , as partly animate and partly inanimate , and the animate Matter is partly rational , and partly sensitive ; Nevertheless , in all those degrees it remains the same onely or meer Matter ; that is , it is nothing else but Matter , and the onely ground in which all changes are made . And therefore I cannot perceive it to be impossible in Nature , as to your Author it seems , That Water should not be transchangeable into Air ; for , that he says , The Air would have increased into a huge bulk , and all Water would have long since failed : It is no consequence , because there is a Mutual transmutation of all figures and parts of Nature , as I declared above ; and when one part is transchanged into another , that part is supplied again by the change of another ; so that there can be no total mutation of kinds or sorts of figures , but onely a mutual change of the particulars . Neither is it of any consequence , when your Author says , That if Water should once beturned into Air , it would always remain Air , because a returning agent is wanting , which may turn Air again into Water . For he might as well say , a Man cannot go or turn backward , being once gone forward . And although he brings a General Rule , That every thing , as much as in it lies , doth desire to remain in it self ; Yet it is impossible to be done , by reason there is no rest in Nature , she being in a perpetual motion , either working to the consistance of a figure , or to the uniting of several parts , or to the dissolving or dividing of several parts , or any other ways . By dissolving , I do not mean annihilating , but such a dissolving of parts as is proper for the altering of such a figure into one or many other figures . But rather then your Author will consent to the transchanging of Water into Air , he will feign several grounds , soils or pavements in the Air , which he calls Peroledes , and so many Flood-gates and Folding-dores , and make the Planets their Key-keepers ; which are pretty Fancies , but not able to prove any thing in Natural Philosophy . And so leaving them to their Author , I rest ,

MADAM , Your humble and faithful Servant .
V. MADAM ,

I Cannot in reason give my consent to your Authors opinion , That Fishes do by the force or vertue of an Ch. The Fiction of Elementary Complexions and Mixtures . inbred Seed transchange simple water into fat , bones , and their own flesh , and that materially they are nothing but water transchanged , and that they return into water by art . For though my opinion is , that bodies change and alter from one figure into another , yet they do not all change into water , neither is water changed into all other figures ; and certainly Fishes do not live nor subsist meerly by Water , but by several other meats , as other animals do ; either by feeding upon other Fishes , the stronger devouring the weaker , or upon Mud , and Grass , and Weeds , in the bottom of Seas , Rivers and Ponds , and the like : As for example , put Fish into a Pool or Sluce , wherein there is not any thing but clear , pure water , and in a short time they will be starved to death for want of Food ; and as they cannot live onely by water , so neither can they breed by the power of water , but by the power of their food , as a more solid substance : And if all Creatures be nourished by those things whereof they consist , then Fishes do not consist of water , being not nourished by water ; for it is not the transchanging of water , by which Fishes live , and by which they produce ; but it is the transchange of food , proceeding from other Creatures , as I mentioned above ? T is true , Water is a proper element for them to live in , but not to live on ; and though I have neither learning , nor experience in Chymistry , yet I believe , that your Author , with all the subtilest Art he had , could not turn or convert all Creatures into pure and simple water , but there would have been dregs and several mixtures left : I will not say , that the Furnace may not rarifie bodies extreamly , but not convert them into such a substance or form as Nature can . And although he thinks Gold is made of Water , yet I do not believe he could convert it into Water by the help of Fire ; he might make it soluble , fluid and rare , but all things that are supple , soluble , flowing and liquid , are not Water ; I am confident no Gas or Blas will , or can transform it , nor no Art whatsoever ; what Nature may do , I know not . But since your Authors opinion is , that Air is also a Primigenial Element , and in its nature a substance , Why doth he not make it a Principle of natural bodies , as well as Water ? I think it had not been so improper to liken Juices to Water ; but to make the onely Principle of the composition and dissolution of all Creatures to be Water , seems to me very improbable . Neither can I admit in reason that the Elements should be called , first , pure , and simple beings ; we might as well call all other creatures , first , pure , and simple beings : for although the word Element sounds as much as Principle , yet they are in my reason no more Principles of Nature , then other Creatures are , there being but one Principle in Nature , out of which all things are composed , viz. the onely matter , which is a pure and simple corporeal substance ; and what Man names impure dregs and filths , these are onely irregular and cross motions of that matter , in respect to the nature of such or such a figure ; or such motions as are not agreeable and sympathetical to our Passions , Humors , Appetites , and the like . Concerning the Contrarieties , Differences and Wars in Nature , which your Author denies , I have spoken thereof already , and though he endeavours in a long discourse to prove , that there is no War in nature ; yet , in my opinion , it is to little purpose , and it makes but a war in the thoughts of the Reader ; I know not what it did in his own . But I observe he appeals often to Divinity to bear him up in Natural Philosophy ; but how the Church doth approve his Interpretations of the Scripture , I know not : Wherefore I will not meddle with them , lest I offend the Truth of the Divine Scripture , wherein I desire to submit to the Judgment of the Church , which is much wiser then I , or any single Person can be . However , for all what your Author says , I do nevertheless verily believe , there is a war between Natural motions : For example ; between the Regular motions of Health , and the Irregular motions of Sickness ; and that things applied do oftentimes give assistance to one side or other , but many times in the conflict , the applied remedies are destroyed , and sometimes they are forced to be Neutrals : Wherefore though the nature of Infinite Matter is simple , and knows of no discord , yet her actions may be cross and opposite : the truth is , Nature could never make such variety , did her actions never oppose each other , but live in a constant Peace and Unity . And thus leaving them to agree , I am confident your Ladiship and I shall never disagree ; for as long as my life doth last , I shall always prove ,

YOur Author condemns the Schools for saying , That Air is moist , or that it may be converted into Water In the ch. of Air. by pressing it together ; bringing an example of an Iron Pipe , wherein Air has been pressed together , which afterwards in its driving out has , like a Hand-gun discharged with Gun-powder , sent a bullet thorow a board or plank . Truly , Madam , concerning the moisture of Air , I am against it , but the transchanging of Air into Water I do verily believe , viz. that some sorts of Air may be contracted or condensed into Water , and that Water again may be dilated into Air , but not readily , commonly and easily by Art , but onely by Nature . Wherefore your Authors Experiment can serve for no proof ; for an artificial trial cannot be an infallible natural demonstration , the actions of Art , and the actions of Nature being for the most part very different , especially in productions and transmutations of natural things : Neither can an alteration of parts , cause an utter destruction of the whole , because when some parts change from their figures , other parts of matter change again into the like figures , by which successive change the continuation of the whole is kept up . Next your Author reproves the Schools for maintaining the opinion , that Air is hot ; for says he , Water , Air , and Earth , are cold by Creation , because without Light , Heat , and the partaking of Life . He might , in my opinion , conclude , as well , that Man is cold by Creation , because a Chameleon , or a Fish is cold , being all of animal kind : But why may not some sorts of Air , Water and Earth be hot , and some be cold , as well as some sorts of Light are hot , and some cold ; and so several other Creatures ? His Reasons prove nothing : for Light doth not make Heat , nor is it the principle of Heat ; and it is no consequence to say , all that is without Light is without Heat , there being many things without Light , which nevertheless are Hot ; But to say , Water , Air , and Earth are cold , because they are without heat , is no proof , but a meer begging of the principle ; for it is but the same thing , as if I should say , this is no Stone , because it is no Glass . And that Water , Air and Earth , do not partake of Life , must be proved first , for that is not granted as yet , there being , according to my opinion , not one Creature that wants Life in all Nature . Again : your Author is of opinion , That Water is the first and chief Principle of all Natural things . But this I can no more believe , then that Water should never change or degenerate from its essence : nay , if your Author means , there shall always be Water in Nature , it is another thing ; but if he thinks that not any part of water doth or can change or degenerate in its nature , and is the principle and chief producer of all other Creatures ; then he makes Water rather a Creator then a Creature ; and it seems , that those Gentiles which did worship Water , were of the same opinion , whereas yet he condemns all Pagan opinions , and all those that follow them . Moreover , I cannot subscribe to his opinion , That Gas and Blas from the Stars do make heat : For heat is made several ways , according to its several sorts ; sor there is a dry heat , and a moist heat , a burning , melting , and evaporating heat , and many more . But as for Meteors , that they are made by Gas and Blas , I can say nothing , by reason I am not skilled in Astrology , and the science of the Heavens , Stars , and Planets ; wherefore if I did offer to meddle with them , I should rather express my Ignorance , then give your Ladiship any solid reasons ; and so I am willing to leave this speculation to others , resting content with that knowledg Nature hath given me without the help of Learning : Which I wholly dedicate and offer to your Ladiship , as becomes ,

MADAM , Your faithful Friend and Servant .
VII . MADAM ,

HAving made mention in my last of your Authors opinion , That Air is in its nature Cold , I thought it fit to take a stricter view of the temper of Air , and to send you withal my own opinion thereof . First of all , I would fain know , what sort of Air your Author means ; for if he thinks there is but one sort of Air , he might as well say , that there is but one sort of Animals , or Vegetables ; whereas yet there are not onely different sorts of animal and vegetable kind , but also different particulars in one and the same sort : As for example ; what difference is not amongst Horses , as between a Barb , a Turk , a Ginnet , a Courser of Naples , a Flanders-horse , a Galloway , an English-horse , and so forth ? not onely in their shapes , but also in their natures , tempers and dispositions ? The like for Cows , Oxen , Sheep , Goats , Dogs , as also for Fowl and Fish , nay , for Men. And as for Vegetables , What difference is there not between Barly and Wheat , and between French-barly , Pine-barly , and ordinary Barly ; as also our English-wheat , Spanish-wheat , Turkish-wheat , Indian-wheat , and the like ? What difference is there not amongst Grapes , as the Malago , Muscadel , and other Grapes , and so of all the rest of Vegetables ? The same may be said of the Elements ; for there is as much difference amongst the Elements as amongst other Creatures . And so of Air : for Air in some places , as in the Indies , especially about Brasilia , is very much different from our air , or from the air that is in other places : Indeed , in every different Climate , you shall find a difference of air , wherefore 't is impossible to assign a certain temper of heat or cold to air in general . But although my sense and reason inform me , that air in its own nature or essence is neither hot nor cold , yet it may become hot or cold , by hot or cold motions ; for the sensitive perceptive motions of Air may pattern out heat or cold ; and hence it is , that in Summer , when as heat predominates , the air is hot ; and in Winter , when as cold predominates , the air is cold . But , perhaps , you will say , air may be cooled by moving it with a Fan , or such like thing which can make wind ; wherefore it follows , that air must needs be naturally cold . I answer , That doth not prove Air to be in its nature cold : for this moving or making of wind may contract or condense the air into cold motions , which may cause a cold wind , like as Ventiducts , where the air running thorow narrow Pipes makes a cold wind . The same may be done with a mans breath ; for if he contract his lips close , his breath will be cold , but if he opens his mouth wide , his breath will be warm . Again : you may say , that rain is congealed by the coldness of the air into Snow , Hail and Ice . I answer ; Frost , Ice , Snow and Hail , do not proceed from the coldness of the air , but rather the coldness of the air proceeds from them ; for Ice , Snow , and Hail , proceed from cold contraction and condensation of a vaporous or watery substance ; and as Frost and Snow cause air to be cold , so Thunder and Lightning cause it to be hot , so long as they last . Thus , Madam , though Air may be altered either to heat or cold , yet it is neither hot nor cold in it self . And this is all for the present that I can say concerning the Temper of Air ; I conclude , and rest ,

MADAM , Your constant Friend , and faithful Servant .
VIII . MADAM ,

HAving hitherto considered your Authors Elements or Principles of Natural things , you will give me leave to present you now with a short view of his Opinions concerning Wind , Vacuum , Rainbows , Thunder , Lightning , Earth-quakes , and the like ; which I will do as briefly as I can , lest I betray my Ignorance ; for I confess my self not to be well versed in the knowledg of Meteors , nor in those things which properly belong to the Mathematicks , as in Astrology , Geography , Opticks , and the like . But your Author says , in the first place , That Natural Wind Ch. Of the Blas of Meteors . is nothing but a flowing Air , moved by the Blas of the Stars . Certainly , Madam , if this were so , then , in my judgment , when the Stars blaze , we should have constant Winds , and the more they blaze , the more violent winds there would be : But I have rather observed the contrary , that when the Stars blaze most apparently , we have the calmest weather either in Summer or Winter . Perchance your Author will say , he doth not mean this apparant and visible Blas , but another invisible Blas . I answer ; I know not , nor cannot conceive any other Blas in the Stars , except I had seen it in a Vision ; neither do I think that Nature her self knows of any other , But your Author doth refer himself upon the Authority of Hypocrates , who says , That not onely the Wind is a blast , but that all Diseases are from blasts ; and that there is in us a Spirit stirring up all things by its Blas ; which Spirit , by a Microcosmical Analogy , or the proportion of a little World , he compares to the blasts of the world . As for my particular , Madam , I dare say , I could never perceive , by my sense and reason , any such blazing Spirit in me ; but I have found by experience , that when my mind and thoughts have been benighted with Melancholy , my Imagination hath been more active and subtil , then when my mind has been clear from dark Melancholy : Also I find that my thoughts and conceptions are as active , if not more , in the night then in the day ; and though we may sometimes dream of several Lights , yet I cannot perceive a constant light in us ; however Light , Blazes , and all those effects are no more then other effects of Nature are ; nor can they have more power on other Creatures , then other Creatures have on them : Neither are they made otherwise then by the corporeal motions of Natural Matter , and are dissolved and transchanged as other Creatures , out of one form or figure into another . Next your Author discoursing a a Ch. Of Vacuum . whether there be any Vacuum in Nature , doth incline to the affirming party , that there is a Vacuum in the Air ; to wit , There is in the air something , that is less then a body , which fills up the emptinesses or little holes and pores in the air , and which is wholly annihilated by fire ; It is actually void of all matter , and is a middle thing between a body and an Incorporeal Spirit , and almost nothing in respect of bodies ; for it came from Nothing , and so may easily be reduced to nothing . All this , Madam , surpasses my capacity ; for I can in no ways conceive any thing between something and nothing , as to be less then something , and more then nothing ; for all that is corporeal in Nature , is to my reason something ; that is , some really existent thing ; but what is incorporeal in Nature , is nothing ; and if there be any absolute vacuum in Nature , as your Author endeavours to prove , then certainly this Vacuum cannot be any thing whatsoever ; for a Vacuum is a pure Nothing . But many ingenious and learned men have brought as many arguments and reasons against Vacuum , as others bring for it , and so it is a thing which I leave to them to exercise their brains withal . The like is the opinion which many maintain concerning Place , viz. that there is a constant succession of Place and Parts , so that when one part removes , another doth succeed in its place ; the truth and manner whereof I was never able to comprehend : for , in my opinion , there can be no place without body , nor no body without place , body and place being all but one thing . But as for the perpetual Creation and annihilation of your Authors Vacuities , give me leave to tell you , Madam , that it would be a more laborious work , then to make a new World , or then it was to make this present World ; for God made this World in six days , and rested the seventh day ; but this is a perpetual making of something out of nothing . Again : concerning Rainbows , your Author says , a a Ch. Of an Irregular Meteor . That a Rainbow is not a natural effect of a natural Cause , but a divine Mystery in its original ; and that it has no matter , but yet is in a place , and has its colours immediately in a place , but in the air mediately , and that it is of the nature of Light . This is indeed a great mystery to my reason ; for I cannot conceive , as I said before , a place without a body , nor how Light and Colours can be bodiless : But as for Rainbows , I have observed , when as water hath been blown up into the air into bubles , that by the reflexion of light on the watery bubles , they have had the like colours of the Rainbow ; and I have heard , that there hath been often seen at the rising and setting of the Sun , Clouds of divers colours ; Wherefore I cannot be perswaded to believe that a Rainbow should not have a natural cause , and consequently be a natural effect ; For that God has made it a sign of the Covenant between him and mortal men , is no proof , that it is not a natural effect ; Neither can I believe that it has not been before the Flood , and before it was made a sign by God , as your Author imagines ; for though it was no sign before the Flood , yet it may nevertheless have had its being and existence before the Flood . Moreover , as for Thunder and Lightning , your Authors opinion is ; That although they may have concurring natural Causes , yet the mover of them is an Incorporeal Spirit , which is the Devil ; who having obtained the Principality of this world , that he may be a certain executer of the Judgments of the chief Monarch , and so the Umpire and Commissioner of Lightning and Thunder , stirs up a monstrous and sudden Blas in the Air , yet under Covenanted Conditions ; for unless his power were bridled by divine Goodness , he would shake the Earth with one stroke so , as to destroy all mortal men : and thus the cracking noise or voice of Thunder is nothing but a spiritual Blas of the Evil Spirit . I will not deny , Madam , that Thunder and Lightning do argue the Power of the most Glorious God , for so do all the rest of the Creatures ; but that this is the onely and immediate cause , which your Author assigns of Thunder and Lightning , I cannot believe ; for surely , in my opinion , Thunder and Lightning are as much natural effects as other Creatures in Nature ; and are not the Devils Blas , for I think they may be made without the help of the Devil ; nay , I believe , he may be as much affraid of Thunder , as those Creatures that live on Earth . But what the causes are , and how Thunder and Lightning are made , I have elsewhere declared more at large , especially in my Philosophical Opinions . Again your Author speaking a a Ch. Of the Earthquake . of the Trembling of the Earth , thinks it is nothing else but the Judgment of God for the sins of Impenitent men . For my part , Madam , I can say little to it , either concerning the divine , or the natural cause of Earthquakes : As for the divine and supernatural Cause , which your Author gives , if it was so , then I wonder much , why God should command Earth-quakes in some parts of the World more frequent then in others . As for example ; we here in these parts have very seldom Earthquakes , and those we have , which is hardly one in many ages , are not so furious , as to do much harm ; and so in many other places of the World , are as few and as gentle Earth-quakes as here ; when as in others , Earth-quakes are very frequent and dreadful : From whence it must needs follow , if Earth-quakes be onely a Judgment from God for the sins of Impenitent Men , and not a natural effect , that then those places , where the Earth is not so apt to tremble , are the habitations of the blessed , and that they , which inhabit those parts that are apt to tremble , are the accursed ; when as yet , in those places where Earthquakes are not usual and frequent , or none at all , People are as wicked and impious , if not more , then in those where Earthquakes are common . But the questions is , Whether those parts which suffer frequent and terrible Earthquakes , would not be so shaken or have such trembling fits , were they uninhabited by Man , or any other animal Creature ? Certainly , in my opinion , they would . But as for the Natural Cause of Earthquakes , you must pardon me , Madam , that I cannot knowingly discourse thereof , by reason I am not so well skilled in Geography , as to know the several Soils , Climats , Parts , Regions , or Countries , nor what disposed matter may be within those parts that are subject to frequent Earthquakes : Onely this I may say , that I have observed , that the light of a small Fire or Candle , will dilate it self round about ; or rather that the air round about the Fire or Candle , will pattern out both its light and its heat . Also I have observed , That a Man in a raging fit of Madness will have such an unsual strength , as ten strong men shall hardly be able to encounter or bind him , when as , this violent fit being past , a single man , nay a youth , may over-master him : Whence I conclude , that the actions , as the motions of Nature , are very powerful when they use their force , and that the ordinary actions of Nature are not so forcible as necessary ; but the extraordinary are more forcible then necessary . Lastly , your Author a a Ch. Of the Birth or Original of Forms . takes great pains to prove , That the Sun with his light rules the Day , and the Moon with hers the Night ; and that the Moon has her own Native light ; and that Bats , Mice , Dormice , Owles , and many others , as also Men , which rise at night , and walk in their sleep , see by the light and power of the Moon ; also that Plants are more plentifully nourished by the night . But lest it might be concluded , that all this is said without any probability of Truth , by reason the Moon doth not every night shine upon the Earth , he makes a difference between the Manner of the Sun 's and Moon 's enlightning the Earth ; to wit , that the Sun strikes his beams in a right line towards the Earth , but the Moon doth not respect the Centre of the World , which is the Earth , in a right line ; but her Centre is always excentrical , and she respects the Earth onely by accident , when she is concentrical with the World ; And therefore he thinks there is another light under the Earth even at Midnight , whereby many Eyes do see , which owes also its rise to the Moon . This opinion of your Author I leave to be examined by those that have skill in Astronomy , and know both the Light and the Course of the Moon : I will onely say thus much , that when the Moon is concentrical , as he calls it , with the World , as when it is Full and New Moon , she doth not shine onely at night , but also in the day , and therefore she may rule the day as well as the night , and then there will be two lights for the ruling of the day , or at least there will be a strife betwixt the Sun and the Moon , which shall rule . But as for Men walking asleep by the light of the Moon , my opinion is , That blind men may walk as well by the light of the Sun , as sleeping men by the light of the Moon . Neither is it probable , that the Moon or her Blas doth nourish Plants ; for in a cold Moon-shiny night they will often die ; but it is rather the Regular motions in well tempered matter that cause fruitful productions and maturity . And so I repose my Pen , lest it trespass too much upon your Patience , resting ,

IN my former , when I related your Authors opinion , concerning Earthquakes , I forgot to tell you , that he counts the the Doctrine of the Schools absurd , when they say that Air , or any Exhalation , is the cause of them : For , says he , There is no place in the Pavements or soils of the Earth , wherein any airy body may be entertained , whether that body be a wind , or an airy exhalation . But since I promised I would not offer to appoint or assign any natural causes of Earthquakes , I have only taken occasion hence to enquire , whether it may not be probably affirmed , that there is air in the bowels of the Earth : And to my reason it seems very probable ; I mean not this Exterior air , flowing about the circumference of the Earth we inhabite ; but such an airy matter as is pure , refined , and subtil , there being great difference in the Elements , as well as in all other sorts of Creatures ; for what difference is there not between the natural heat of an animal , and the natural heat of the Sun ? and what difference is there not between the natural moisture of an Animal , and the natural moisture of Water ? And so for the Purity of Air , Dryness of Earth , and the like : Nay , there is great difference also in the production of those Effects : As for example ; the heat of the Earth is not produced from the Sun , nor the natural heat in Animals , nor the natural heat in Vegetables ; for if it were so , then all Creatures in one Region or place of the Earth would be of one temper . As for example : Poppy , Night-shade , Lettuce , Thyme , Sage , Parsly , &c. would be all of one temper and degree , growing all in one Garden , and upon one patch of Ground , whereon the Sun equally casts his beams , when as yet they are all different in their natural tempers and degrees . And so certainly there is Air , Fire , and Water , in the bowels of the Earth , which were never made by the Sun , the Sea , and this Exterior elemental Air. Wherefore those , in my opinion , are in gross Errors , who imagine that these Interior Effects in the Earth are produced from the mentioned Exterior Elements , or from some other forreign and external Causes ; for an external cause can onely produce an external effect , or be an occasion to the production of such or such an effect , but not be the immediate efficient or essential cause of an interior natural effect in another Creature , unless the Interior natures of different Creatures have such an active power and influence upon each other , as to work interiously at a distance , such effects as are proper and essential to their Natures , which is improbable ; for though their natures and dispositions may mutually agree and sympathize , yet their powers cannot work upon their Interior Natures so , as to produce internal natural effects and proprieties in them . The truth is , it cannot be ; for as the Cause is , so is the Effect ; and if the Cause be an exterior Cause , the Effect must prove so too : As for example ; the heat of the Sun , and the heat of the Earth , although they may both agree , yet one is not the cause of the other ; for the Suns heat cannot pierce into the bowels of the Earth , neither can the heat of the Earth ascend so far as to the Center of the Sun : As for the heat of the Earth , it is certain enough , and needs no proof ; but as for the heat of the Sun , our senses will sufficiently inform us , that although his beams are shot forth in direct lines upon the face of the Earth , yet they have not so much force , as to pierce into a low Celler or Vault ; Wherefore it is not probable , that the Earth hath its natural heat from the Sun , and so neither its dryness from the Air , nor its moisture from the Sea , but these interior effects in the Earth proceed from some other interior causes . And thus there may be great difference between the heat , cold , moisture , and drought which is in the Elements , and between those which are in Vegetables , Minerals , and Animals , not onely in their General kinds , but also in their Particulars : And not onely a difference in the aforesaid qualities of heat , cold , moisture , and drought , but also in all other motions , as Dilations , Contractions , Rarefactions , Densations , &c. nay , in their Mixtures and Temperaments : As for example ; the temper of a Mineral is not the temper of an Animal , or of a Vegetable , neither is the temper of these the temper of the exterior Elements , no more then the temper of the Elements is the temper of them ; for every Creature has a temper natural and peculiar to it self , nay , every particular Creature , has not onely different tempers , compositions , or mixtures , but also different productions ; or else , if there were no difference in their productions ; every Creature would be alike , when as yet there are seldom two that do exactly resemble each other . But I desire you to understand me well , Madam , when I speak of Particular heats , colds , droughts , and moistures ; for I do not believe that all Creatures are made out of the four Elements , no more , then that the Elements are produced from other Creatures , for the Matter of all Creatures is but one and the same ; but although the Matter is the same , nevertheless , the Tempers , Compositions , Productions , Motions , &c. of particular Creatures , may be different , which is the cause of their different exterior figures , or shapes , as also of their different Interiour Natures , Qualities , Properties , and the like . And so , to conclude , there is no impossibility or absurdity in affirming , that there may be Air , Fire , and Water , in the bowels of the Earth proper for those Creatures , which are in her , although not such an Elemental Air , Fire and Water , as is subject here to our senses ; but another kind of Air , Fire and Water , different from those . But this being a subject for Learned and Ingenious men to work and contemplate upon , better , perhaps , then I can do , I will leave it to them , and so remain ,

YOur Author mentioning in his Works , several Seeds of several Creatures , makes me express my opinion thus in short concerning this Subject : Several Seeds seem to me no otherwise then several Humours , or several Elements , or several other Creatures made of one and the same Matter , that produce one thing out of another , and the barrenness of seeds proceeds either from the irregularity of their natural motions , or from their unaptness or unactivity of producing . But it is to be observed , Madam , that not every thing doth produce always its like , but one and the same thing , or one and the same Creature , hath many various and different productions ; for sometimes Vegetables do produce Animals , Animals produce Minerals , Minerals produce Elements , and Elements again Minerals , and so forth : for proof I will bring but a mean and common example . Do not Animals produce Stones , some in one , and some in another part of their bodies , as some in the Heart , some in the Stomack , some in the Head , some in the Gall , some in the Kidnies , and some in the Bladder ? I do not say , that this Generation of Stone is made the same way as the natural generation of Animals , as , for example , Man is born of his Parents ; but I speak of the generation or production of Creatures in general , for otherwise all Creatures would be alike , if all generations were after one and the same manner and way . Likewise do not Fruits , Roots , Flowers and Herbs , produce Worms ? And do not Stones produce Fire ? witness the Flint . And doth not Earth produce Metal ? 'T is true , some talk of the seed of Metals , but who with all his diligent observations could find it out as yet ? Wherefore it is , in my opinion , not probable , that Minerals are produced by way of seeds . Neither can I perceive that any of the Elements is produced by seed , unless Fire , which seems , to my sense and reason , to encrease numerously by its seed , but not any other of the Elements . And thus productions are almost as various as Creatures , or rather parts of Creatures , are ; for we see how many productions there are in one animal body , as the production of flesh , bones , marrow , brains , gristles , veines , sinews , blood , and the like , and all this comes from Food , and Food from some other Creatures , but all have their original from the onely matter , and the various motions of Nature . And thus , in my opinion , all things are made easily , and not by such constrained ways as your Author describes , by Gas , Blas , Ideas , and the like ; for I am confident , Nature has more various ways of producing natural things then any Creature is able to conceive . I 'le give another example of Vegetables , I pray you but to consider , Madam , how many several ways Vegetables are produced , as some by seeds , some by slips , some by grafts , &c. The graft infuses and commixes with the whole stock and the branches , and these do the like with the graft : As for example ; an Apple grafted in Colewort produces Apples ; but those Apples will have a taste and sent of the Colewort , which shews that several parts of several Creatures mix , joyn , and act together ; and as for seeds , they are transchanged wholly , and every part thereof into the produced fruit , and every part of the seed makes a several production by the help of the co-working parts of the Earth , which is the reason that so many seeds are produced from one single seed ; But Producers , that waste not themselves in productions , do not produce so numerously as those that do dissolve ; yet all Creatures increase more or less , according to their supplies or assistances ; for seeds will encrease and multiply more in manured and sertile then in barren grounds ; nay , if the ground be very barren , no production at all will be ; which shews , that productions come not barely from the seed , but require of necessity some assistance , and therefore neither Archeus , nor seminal Ideas , nor Gas , nor Blas , would do any good in Vegetables , if the ground did not assist them in their generations or productions , no more then a house would be built without the assistance of labourers or workmen ; for let the materials lie never so long , surely they will never joyn together of themselves to the artificial structure of an house . Wherefore since there is so much variety in the production of one kind of Creatures , nay of every particular in every kind , what needs Man to trouble his brain for the manner and way to describe circumstantially every particular production of every Creature by seminal or printing Ideas , or any other far-fetched termes , since it is impossible to be done ? And as for those Creatures whose producers are of two different sorts , as a Mule bred of an Asse and a Horse , and another Creature bred of a Cony and a Dormouse ; all which your Author thinks a a In the Ch. the Position is demonstrated : and in the ch. called the Authority of the Duumvirate . do take more after their mother then their father , more after the breeder then the begetter ; I will not eagerly affirm the contrary , although it seems to me more probable : But this I can say , that I have observed by experience , that Faunes and Foales have taken more after the Male then after the Female ; for amongst many several colour'd Deer , I have seen but one milk white Doe ; and she never brought forth a white Faun , when as I have seen a white Buck beget white and speckled Faunes of black and several coloured Does . Also in Foals I have observed , that they have taken more after the Male then after the Female , both in shape and colour . And thus I express no more , but what I have observed my self ; others may find out more examples ; these are sufficient for me ; so I leave them , and rest ,

YOu will cease to wonder , that I am not altogether capable to understand your Authors opinions in Natural Philosophy , when you do but consider , that his expressions are for the most part so obscure , mystical and intricate , as may puzzle any brain that has not the like Genius , or the same Conceptions with your Author ; wherefore I am forced oftentimes to express my ignorance rather , then to declare to you the true sense of his opinions . In the number of these is his discourse of a Middle Life a a Ch. called Magnum oportet . , viz. That the qualities of a middle life do remain in things that are transchanged : For I cannot understand what he means by a middle life ; whether it be a life that is between the strongest and weakest , or whether he means a life between the time of production and dissolution , or between the time of conception and production ; or whether he means a life that is between two sorts of substances , as more then an Animal , and not so high and excellent as an Angel ; or whether he means a middle life for places , as neither in Heaven nor in Hell , but in Purgatory , or neither in , nor out of the world , or any other kind of life : Wherefore I 'le leave this Hermaphroditical or neutral life to better understandings then mine . Likewise I must confess my disability of conceiving the overshadowing of his Archeus , and how it brings this middle life into its first life . For concerning Generation , I know of none that is performed by overshadowing , except it be the miraculous conception of the blessed Virgin , as Holy Writ informs us ; and I hope your Author will not compare his Archeus to the Holy Spirit ; But how a middle life may be brought again into the first life , is altogether unconceivable to me : And so is that , when he says , that the first life of the Fruit is the last of the seed ; for I cannot imagine , that the seed dies in the fruit ; but , in my opinion , it lives rather in the fruit , and is numerously increased , as appears by the production of seed from the fruit . But the most difficult of all to be understood , are his Ideas , which he makes certain seminal Images , Formal Lights , and operative means , whereby Of the Ideas of Diseases . the soul moves and governs the body ; whose number and variety is so great , as it transcends my capacity , there being Ideas of Inclination , of Affection , of Consideration or Judgment , of Passion , and these either mild , or violent , besides a great number of Archeal and forreign Ideas . Truly , Madam , I cannot admire enough the powerful effects of these Ideas , they themselves being no substances or material Creatures ; For how that can pierce , seal , and print a figure , which hath neither substance nor matter , my reason is not able to comprehend , since there can be no figure without matter or substance , they being inseparably united together , so , that where figure is , there is also substance , and where substance is , there is also figure ; neither can any figure be made without a substance . You may say , Ideas , though they are not material or corporeal beings themselves , yet they may put on figures , and take bodies when they please : I answer , That then they can do more then Immaterial Spirits ; for the Learned say , That Immaterial Spirits are Immaterial substances ; but your Author says , that Ideas are no substances ; and I think it would be easier for a substance to take a body , then for that which is no substance : But your Author might have placed his Ideas as well amongst the number of Immaterial Spirits , to wit , amongst Angels and Devils , and then we should not have need to seek far for the causes of the different natures and dispositions of Mankind , but we might say , that Ill-natured men proceeded from Evil , and Good-natured men from Good Spirits or Ideas . However , Madam , I do not deny Ideas , Images , or Conceptions of things , but I deny them onely to be such powerful beings and Principal efficient Causes of Natural effects ; especially they being to your Author neither bodies nor substances themselves . And as for the Figure of a Cherry , which your Author makes so frequent a repetition of , made by a longing Woman on her Child ; I dare say that there have been millions of Women , which have longed for some or other thing , and have not been satisfied with their desires , and yet their Children have never had on their bodies the prints or marks of those things they longed for : but because some such figures are sometimes made by the irregular motions of animate Matter , would this be a sufficient proof , that all Conceptions , Ideas and Images have the like effects , after the same manner , by piercing or penetrating each other , and sealing or printing such or such a figure upon the body of the Child ? Lastly , I cannot but smile when I read that your Author makes a Disease proceed from a non-being to a substantial being : Which if so , then a disease , according to his opinion , is made as the World was , that is , out of Nothing ; but surely luxurious persons find it otherwise , who eat and drink more then their natural digestive motions can dispose ; for those that have infirm bodies , caused by the irregular motions of animate matter , find that a disease proceeds from more then a non-being . But , Madam , I have neither such an Archeus , which can produce , in my mind , an Idea of Consent or approbation of these your Authors opinions , nor such a light that is able to produce a beam of Patience to tarry any longer upon the examination of them ; Wherefore I beg your leave to cut off my discourse here , and onely to subscriibe my self , as really I am ,

MADAM , Your humble and faithful Servant .
XII . MADAM ,

I Cannot well apprehend your Authors meaning , when he says , a a Ch. Narure is ignorant of Contraries That Nature doth rise from its fall ; for if he understands Nature in general , I cannot imagine how she should fall and rise ; for though Man did fall , yet Nature never did , nor cannot fall , being Infinite : And therefore in another place , b b In the Hist. of Tartar . when he saith , that Nature first being a beautiful Virgin , was defiled by sin ; not by her own , but by Mans sin , for whose use she was created ; I think it too great a presumption and arrogancy to say that Infinite Nature was not onely defiled by the sin of Man , but also to make Man the chief over all Nature , and to believe Nature was onely made for his sake ; when as he is but a small finite part of Infinite Nature , and almost Nothing in comparison to it . But I suppose your Author doth not understand Nature in general , but onely the nature of some Particulars , when he speaks of the fall and rise of Nature ; however , this fall and rise of the nature of Particulars , is nothing but a change of their natural motions . And so likewise , I suppose , he understands the nature of Particulars , when he says in another place , c c Ch. Disease is an unknown guest . That Nature in diseases is standing , sitting , and lying ; for surely Nature in general has more several postures then sitting , standing , or lying : As also when he speaks d d Nature is ignorant of Contraries . of the Vertues and Properties that stick fast in the bosom of Nature , which I conceive to be a Metaphorical expression ; although I think it best to avoid Metaphorical , similizing , and improper expressions in Natural Philosophy , as much as one can ; for they do rather obscure then explain the truth of Nature ; nay , your Author himself is of this opinion e e Ch. The Image of the Ferment begets the Mass with Child . , and yet he doth nothing more frequent then bring in Metaphors and similitudes . But to speak properly , there is not any thing that sticks fast in the bosom of Nature , for Nature is in a perpetual motion : Neither can she be heightened or diminished by Art ; for Nature will be Nature in despite of her Hand-maid . And as for your Authors opinion , That there are no Contraries in Nature , I am quite of a contrary mind , viz. that there is a Perpetual war and discord amongst the parts of Nature , although not in the nature and substance of Infinite Matter , which is of a simple kind , and knows no contraries in it self , but lives in Peace , when as the several actions are opposing and crossing each other ; and truly , I do not believe , that there is any part or Creature ofNature , that hath not met with opposers , let it be never so small or great . But as War is made by the division of Natures parts , and variety of natural actions , so Peace is caused by the unity and simplicity of the nature and essence of onely Matter , which Nature is peaceable , being always one and the same , and having nothing in it self to be crossed or opposed by ; when as the actions of Nature , or natural Matter , are continually striving against each other , as being various and different . Again your Author says , That a Specifical being cannot be altered but by Fire , and that Fire is the Death of other Creatures : also that Alchymy , as it brings many things to a degree of greater efficacy , and stirs up a new being , so on the other hand again , it by a privy filching doth enfeeble many things . I , for my part , wonder , that Fire , being as your Author says , no substantial body , but substanceless in its nature , should work such effects ; but however , I believe there are many alterations without Fire , and many things which cannot be altered by Fire . What your Authors meaning is of a new being , I know not ; for , to my reason , there neither is , nor can be made any new being in Nature , except we do call the change of motions and figures a new Creation ; but then an old suit turned or dressed up may be called new too . Neither can I conceive his Filching or Stealing : For Nature has or keeps nothing within her self , but what is her own ; and surely she cannot steal from her self ; nor can Art steal from Nature ; she may trouble Nature , or rather make variety in Nature , but not take any thing from her , for Art is the insnarled motions of Nature : But your Author , being a Chymist , is much for the Art of Fire , although it is impossible for Art to work as Nature doth ; for Art makes of natural Creatures artificial Monsters , and doth oftner obscure and disturb Natures ordinary actions , then prove any Truth in Nature . But Nature loving variety , doth rather smile at Arts follies , then that she should be angry with her curiosity : like as for example , a Poet will smile in expressing the part or action of a Fool. Wherefore Pure natural Philosophers , shall by natural sense and reason , trace Natures ways , and observe her actions , more readily then Chymists can do by Fire and Furnaces ; for Fire and Furnaces do often delude the Reason , blind the Understanding , and make the Judgment stagger . Nevertheless , your Author is so taken with Fire , that from thence he imagines a Formal Light , which he believes to be the Tip-top of Life ; but certainly , he had , in my opinion , not so much light as to observe , that all sorts of light are but Creatures , and not Creators ; for he judges of several Parts of Matter , as if they were several kinds of Matter , which causes him often to err , although he conceits himself without any Error . In which conceit I leave him , and rest ,

MADAM , Your faithful Friend and humble Servant .
XIII . MADAM ,

THe Art of Fire , as I perceive , is in greater esteem and respect with your Author , then Nature her self : For he says , a a Ch. Called , The Essay of a Meteor . That some things can be done by Art , which Nature cannot do ; nay he calls b b Ch. Heat doth not digest efficiently , but excitingly . Art The Mistress of Nature , and subjects whole Nature unto Chymical speculation ; For , nothing , says he , c c Ch. The ignorant natural Philosophy of Aristotle and Galen . doth more fully bring a Man , that is greedy of knowing , to the knowledg of all things knowable , then the Fire ; for the root or radical knowledg of natural things consists in the Fire : d d Ch. A modern Pharmacapoly and dispensatory . It pierces the secrets of Nature , and causes a further searching out in Nature , then all other Sciences , being put together ; and pierces even into the utmost depths of real truth : e e Ch. Of the Power of Medicines . It creates things which never were before . These , and many more the like expressions , he has in the praise of Chymistry . And truly , Madam , I cannot blame your Author , for commending this Art , because it was his own profession , and no man will be so unwise as to dispraise his own Art which he professes ; but whether those praises and commendations do not exceed truth , and express more then the Art of Fire can perform , I will let those judg , that have more knowledg therein then I : But this I may say , That what Art or Science soever is in Nature , let it be the chief of all , yet it can never be call'd the Mistress of Nature , nor be said to perform more then Nature doth , except it be by a divine and supernatural Power ; much less to create things which never were before , for this is an action which onely belongs to God : The truth is , Art is but a Particular effect of Nature , and as it were , Nature's Mimick or Fool , in whose playing actions she sometimes takes delight ; nay , your Author confesses it himself , when he calls f f Ch. Heat doth not digest efficiently , bnt excitingly . the Art of Chymistry , Nature's emulating Ape , and her Chamber-maid , and yet he says , she is now and then the Mistress of Nature ; which in my opinion doth not agree : for I cannot conceive how it is possible to be a Chamber-maid , and yet to be the Mistress too ; I suppose your Author believes , they justle sometimes each other out , or take by turns one anothers place . But whatever his opinion be , I am sure , that the Art of Fire cannot create and produce so , as Nature doth , nor dissolve substances so as she doth , nor transform and transchange , as she doth , nor do any effect like Nature : And therefore I cannot so much admire this Art as others do , for it appears to me , rather to be a troubler , then an assistant to Nature , producing more Monsters then perfect Creatures ; nay , it rather doth shut the Gates of Truth , then unlock the Gates of Nature : For how can Art inform us of Nature , when as it is but an effect of Nature ? You may say , The cause cannot be better known then by its effect ; for the knowledg of the effect , leads us to the knowledg of the cause . I answer , T is true : but you will consider , that Nature is an Infinite cause , and has Infinite effects ; and if you knew all the Infinite effects in nature , then perhaps you might come to some knowledg of the cause ; but to know nature by one single effect , as art is , is impossible ; nay , no man knows this particular effect as yet perfectly ; For who is he , that has studied the art of fire so , as to produce all that this art may be able to afford ? witness the Philosophers-stone . Besides , how is it possible to find out the onely cause by so numerous variations of the effects ? Wherefore it is more easie , in my opinion , to know the various effects in Nature by studying the Prime cause , then by the uncertain study of the inconstant effects to arrive to the true knowledg of the prime cause ; truly it is much easier to walk in a Labyrinth without a Guide , then to gain a certain knowledg in any one art or natural effect , without Nature her self be the guide , for Nature is the onely Mistress and cause of all , which , as she has made all other effects , so she has also made arts for varieties sake ; but most men study Chymistry more for imployment , then for profit ; not but that I believe , there may be some excellent Medicines found out and made by that art , but the expence and labour is more then the benefit ; neither are all those Medicines sure and certain , nor in all diseases safe ; neither can this art produce so many medicines as there are several diseases in Nature , and for the Universal Medicine , and the Philosophers-stone or Elixir , which Chymists brag of so much ; it consists rather in hope and expectation , then in assurance ; for could Chymists find it out , they would not be so poor , as most commonly they are , but richer then Solomon was , or any Prince in the World , and might have done many famous acts with the supply of their vast Golden Treasures , to the eternal and immortal fame of their Art ; nay , Gold being the Idol of this world , they would be worshipped as well for the sake of Gold , as for their splendorous Art ; but how many have endeavored and laboured in vain and without any effect ? Gold is easier to be made , then to be destroyed , says your Author a a Ch. The first Principles of the Chymists , nor the Essences of the same are of the Army of Diseases . , but I believe one is as difficult or impossible , nay more , then the other ; for there is more probability of dissolving or destroying a natural effect by Art , then of generating or producing one ; for Art cannot go beyond her sphere of activity , she can but produce an artificial effect , and Gold is a natural Creature ; neither were it Justice , that a particular creature of Nature should have as much power to act or work as Nature her self ; but because neither Reason , nor Art has found out as yet such a powerful opposite to Gold , as can alter its nature ; men therefore conclude that it cannot be done . Your Author relates a a In the Ch. Of Life Eternal , and in the Ch. Of the Tree of Life . to have seen the Gold-making stone , which he says , was of colour such , as Saffron is in its powder , but weighty and shining like unto powder'd Glass ; one fourth part of one grain thereof , ( a grain he reckons the six hundredth part of one ounce ) being projected upon eight ounces of Quicksilver made hot in a Crucible , and straight way there were found eight ounces , and a little less then eleven grains of the purest Gold ; therefore one onely grain of that powder had transchanged 19186 parts of Quicksilver , equal to it self , into the best Gold . Truly , Madam , I wish with all my heart , the poor Royalists had had some quantity of that powder ; and I assure you , that if it were so , I my self would turn a Chymist to gain so much as to repair my Noble Husbands losses , that his noble family might flourish the better . But leaving Gold , since it is but a vain wish , I do verily believe , that some of the Chymical medicines do , in some desperate cases , many times produce more powerful and sudden effects then the medicines of Galenistsi , and therefore I do not absolutely condemn the art of Fire , as if I were an enemy to it ; but I am of an opinion , that my Opinions in Philosophy , if well understood , will rather give a light to that art , then obscure its worth ; for if Chymists did but study well the corporeal motions or actions of Natures substantial body ; they would , by their observations , understand Nature better , then they do by the observation of the actions of their Art ; and out of this consideration and respect , I should almost have an ambition , to become an Artist in Chymistry , were I not too lazie and tender for that imployment ; but should I quit the one , and venture the other , I am so vain as to perswade my self , I might perform things worthy my labour upon the ground of my own Philosophy , which is substantial Life , Sense , and Reason ; for I would not study Salt , Sulphur , and Mercury , but the Natural motions of every Creature , and observe the variety of Natures actions . But , perchance , you will smile at my vain conceit , and , it may be , I my self , should repent of my pains unsuccessfully bestowed , my time vainly spent , my health rashly endangered , and my Noble Lords Estate unprofitably wasted , in fruitless tryals and experiments ; Wherefore you may be sure , that I will consider well before I act ; for I would not lose Health , Wealth , and Fame , and do no more then others have done , which truly is not much , their effects being of less weight then their words . But in the mean time , my study shall be bent to your service , and how to express my self worthily ,

I Have read your Authors discourse concerning Sensation a a Of the Disease of the Stone . Ch. 9. , but it was as difficult to me to understand it , as it was tedious to read it ; Truly , all the business might have have been easily declared in a short Chapter , and with more clearness and perspicuity : For Sensation , is nothing else but the action of sense proceeding from the corporeal sensitive motions , which are in all Creatures or parts of Nature , and so all have sense and sensation , although not alike after one and the same manner , but some more , some less , each according to the nature and propriety of its figure . But your Author speaks of Motion without Sense , and Sense without Motion , which is a meer impossibility ; for there is not , nor cannot be any Motion in Nature without Sense , nor any Sense without Motion ; there being no Creature without self-motion , although not always perceptible by us , or our external senses ; for all motion is not exteriously local , and visible . Wherefore , not any part of Nature , according to my opinion , wants Sense and Reason , Life and Knowledg ; but not such a substanceless Life as your Author describes , but a substantial , that is ; a corporeal Life . Neither is Light the principle of Motion , but Motion is the principle of Light : Neither is Heat the principle of Motion , but its effect as well as Cold is ; for I cannot perceive that Heat should be more active then Cold. Neither is there any such thing as Unsensibleness in Nature , except it be in respect of some particular Sensation in some particular Figure : As for example , when an Animal dies , or its Figure is dissolved from the Figure of an Animal ; we may say it hath not animal sense or motion , but we cannot say , it hath no sense or motion at all ; for as long as Matter is in Nature , Sense and Motion will be ; so that it is absurd and impossible to believe , or at least to think , that Matter , as a body , can be totally deprived of Life , Sense , and Motion , or that Life can perish and be corrupted , be it the smallest part of Matter conceivable , and the same turned or changed into millions of Figures ; for the Life and Soul of Nature is self-moving Matter , which by Gods Power , and leave , is the onely Framer and Maker , as also the Dissolver and Transformer of all Creatures in Nature , making as well Light , Heat , and Cold , Gas , Blas , and Ferments , as all other natural Creatures beside , as also Passions , Appetites , Digestions , Nourishments , Inclination , Aversion , Sickness and Health ; nay , all Particular Ideas , Thoughts , Fancies , Conceptions , Arts , Sciences , &c. In brief , it makes all that is to be made in Nature . But many great Philosophers conceive Nature to be fuller of Intricacy , Difficulty , and Obscurity , then she is , puzling themselves about her ordinary actions , which yet are easie and free , and making their arguments hard , constrained , and mystical , many of them containing neither sense nor reason ; when as , in my opinion , there is nothing else to be studied in Nature , but her substance and her actions . But I will leave them to their own Fancies and Humors , and say no more , but rest ,

COncerning Sympathy and Antipathy , and attractive or magnetick Inclinations , which some do ascribe to the influence of the Stars , others to an unknown Spirit as the Mover , others to the Instinct of Nature , hidden Proprieties , and certain formal Vertues ; but your Author a a Ch. Of Sympathetical Mediums . doth attribute to directing Ideas , begotten by their Mother Charity , or a desire of Good Will , and calls it b b In the Plague-Grave . a Gift naturally inherent in the Archeusses of either part : If you please to have my opinion thereof , I think they are nothing else but plain ordinary Passions and Appetites . As for example : I take Sympathy , as also Magnetisme or attractive Power , to be such agreeable Motions in one part or Creature , as do cause a Fancy , love and desire to some other part or Creature ; and Antipathy , when these Motions are disagreeable , and produce contrary effects , as dislike , hate and aversion to some part or Creature . And as there are many sorts of such motions , so there are many sorts of Sympathyes and Antipathyes , or Attractions and Aversions , made several manners or ways ; For in some subjects , Sympathy requires a certain distance ; as for example , in Iron and the Loadstone ; for if the Iron be too far off , the Loadstone cannot exercise its power , when as in other subjects , there is no need of any such certain distance , as betwixt the Needle and the North-pole , as also the Weapon-salve ; for the Needle will turn it self towards the North , whether it be near or far off from the North-pole ; and so , be the Weapon which inflicted the wound , never so far from the wounded Person , as they say , yet it will nevertheless do its effect : But yet there must withal be some conjunction with the blood ; for as your Author mentions * * In the Magnetick cnre of Wounds . , the Weapon shall be in vain anointed with the Unguent , unless it be made bloody , and the same blood be first dried on the same Weapon . Likewise the sounding of two eights when one is touched , must be done within a certain distance : the same may be said of all Infectious and catching Diseases amongst Animals , where the Infection , be it the Infected Air , or a Poysonous Vapour , or any thing else , must needs touch the body , and enter either through the Mouth , or Nostrils , or Ears , or Pores of the body ; for though the like Antipathies of Infectious Diseases , as of the Plague , may be in several places far distant and remote from each other at one and the same time , yet they cannot infect particular Creatures , or Animals , without coming near , or without the sense of Touch : For example ; the Plague may be in the East Indies , and in this Kingdom , at one and the same time , and yet be strangers to each other ; for although all Men are of Mankind , yet all have not Sympathy or Antipathy to each other ; the like of several Plagues , although they be of the same kind of disease , yet , being in several places at one time , they may not be a kin to each other , nor one be produced by the other , except the Plague be brought over out of an infected Country , into a sound Country , by some means or other . And thus some Sympathy and Antipathy is made by a close conjunction , or corporeal uniting of parts , but not all ; neither is it required , that all Sympathy and Antipathy must be mutual , or equally in both Parties , so that that part or party , which has a Sympathetical affection or inclination to the other , must needs receive the like sympathetical affection from that part again ; for one man may have a sympathetical affection to another man , when as this man hath an antipathetical aversion to him ; and the same may be , for ought we know , betwixt Iron and the Loadstone , as also betwixt the Needle and the North ; for the Needle may have a sympathy towards the North , but not again the North towards the Needle ; and so may the Iron have towards the Loadstone , but not again the Loadstone towards the Iron : Neither is Sympathy or Antipathy made by the issuing out of any invisible rayes , for then the rays betwixt the North and the Needle would have a great way to reach : But a sympathetical inclination in a Man towards another , is made either by sight , or hearing ; either present , or absent : the like of infectious Diseases . I grant , that if both Parties do mutually affect each other , and their motions be equally agreeable ; then the sympathy is the stronger , and will last the longer , and then there is a Union , Likeness , or Conformableness , of their Actions , Appetites , and Passions ; For this kind of Sympathy works no other effects , but a conforming of the actions of one party , to the actions of the other , as by way of Imitation , proceeding from an internal sympathetical love and desire to please ; for Sympathy doth not produce an effect really different from it self , or else the sympathy betwixt Iron and the Loadstone would produce a third Creature different from themselves , and so it would do in all other Creatures . But as I mentioned above , there are many sorts of attractions in Nature , and many several and various attractions onely in one sort of Creatures , nay , so many in one particular as not to be numbred ; for there are many Desires , Passions , and Appetites , which draw or intice a man to something or other , as for example , to Beauty , Novelty , Luxury , Covetousness , and all kinds of Vertues and Vices ; and there are many particular objects not in every one of these , as for example , in Novelty ? For there are so many several desires to Novelty , as there are Senses , and so many Novelties that satisfie those desires , as a Novelty to the Ear , a Novelty to the Sight , to Touch , Taste , and Smell ; besides in every one of these , there are many several objects ; To mention onely one example , for the novelty of Sight ; I have seen an Ape , drest like a Cavalier , and riding on Horse-back with his sword by his side , draw a far greater multitude of People after him , then a Loadstone of the same bigness of the Ape would have drawn Iron ; and as the Ape turn'd , so did the People , just like as the Needle turns to the North ; and this is but one object in one kind of attraction , viz. Novelty : but there be Millions of objects besides . In like manner good Cheer draws abundance of People , as is evident , and needs no Demonstration . Wherefore , as I said in the beginning , Sympathy is nothing else but natural Passions and Appetites , as Love , Desire , Fancy , Hunger , Thirst , &c. and its effects are Concord , Unity , Nourishment , and the like : But Antipathy is Dislike , Hate , Fear , Anger , Revenge , Aversion , Jealousie , &c. and its effects are Discord , Division , and the like . And such an Antipathy is between a Wolf and a Sheep , a Hound and a Hare , a Hawk and a Partridg , &c. For this Antipathy is nothing else but fear in the Sheep to run away from the Wolf , in the Hare to run from the Hound , and in the Partridg to flie from the Hawk ; for Life has an Antipathy to that which is named Death ; and the Wolf's stomack hath a sympathy to food , which causes him to draw neer , or run after those Creatures he has a mind to feed on . But you will say , some Creatures will fight , and kill each other , not for Food , but onely out of an Antipathetical nature . I answer : When as Creatures fight , and endeavour to destroy each other , if it be not out of necessity , as to preserve and defend themselves from hurt or danger , then it is out of revenge , or anger , or ambition , or jealousie , or custom of quarrelling , or breeding . As for example : Cocks of the Game , that are bred to fight with each other , and many other Creatures , as Bucks , Staggs , and the like , as also Birds , will fight as well as Men , and seek to destroy each other through jealousie ; when as , had they no Females amongst them , they would perhaps live quiet enough , rather as sympathetical Friends , then antipathetical Foes ; and all such Quarrels proceed from a sympathy to their own interest . But you may ask me , what the reason is , that some Creatures , as for example , Mankind , some of them , will not onely like one sort of meat better then another of equal goodness and nourishment , but will like and prefer sometimes a worse sort of meat before the best , to wit , such as hath neither a good taste nor nourishment ? I answer : This is nothing else , but a particular , and most commonly an inconstant Appetite ; for after much eating of that they like best , especially if they get a surfeit , their appetite is changd to aversion ; for then all their feeding motions and parts have as much , if not more antipathy to those meats , as before they had a sympathy to them . Again , you may ask me the reason , why a Man seeing two persons together , which are strangers to him , doth affect one better then the other ; nay , if one of these Persons be deformed or ill-favoured , and the other well-shaped and handsom ; yet it may chance , that the deformed Person shall be more acceptable in the affections and eyes of the beholder , then he that is handsom ? I answer : There is no Creature so deformed , but hath some agreeable and attractive parts , unless it be a Monster , which is never loved , but for its rarity and novelty , and Nature is many times pleased with changes , taking delight in variety : and the proof that such a sympathetical affection proceeds from some agreeableness of Parts , is , that if those persons were vail'd , there would not proceed such a partial choice or judgment from any to them . You may ask me further , whether Passion and Appetite are also the cause of the sympathy which is in the Loadstone towards Iron , and in the Needle towards the North ? I answer , Yes : for it is either for nourishment , or refreshment , or love and desire of association , or the like , that the Loadstone draws Iron , and the Needle turns towards the North. The difference onely betwixt the sympathy in the Needle towards the North , and betwixt the sympathy in the Loadstone towards the Iron is , that the Needle doth always turn towards the North , but the Loadstone doth not always draw Iron : The reason is , because the sympathy of the Needle towards the North requires no certain distance , as I said in the beginning ; and the North-pole continuing constantly in the same place , the Needle knows whither to turn ; when as the sympathy between the Loadstone and Iron requires a certain distance , and when the Loadstone is not within this compass or distance , it cannot perform its effect , to wit , to draw the Iron , but the effect ceases , although the cause remains in vigour . The same may be said of the Flower that turns towards the Sun ; for though the Sun be out of sight , yet the Flower watches for the return of the Sun , from which it receives benefit : Like as faithful Servants watch and wait for their Master , or hungry Beggers at a Rich man's door for relief ; and so doth the aforesaid Flower ; nay , not the Flower onely , but any thing that has freedom and liberty of motion , will turn towards those Places or Creatures whence it expects relief . Concerning ravenous Beasts that feed on dead Carcasfes , they , having more eager appetites then food , make long flights into far distant Countries to seek food to live on , but surely , I think , if they had food enough at home , although not dead Carcasses , they would not make such great Journies ; or if a battel were fought , and many slain , and they upon their journey should meet with sufficient food , they would hardly travel further before they had devoured that food first : But many Birds travel for the temper of the Air , as well as for food , witness Woodcocks , Cranes , Swallows , Fieldfares , and the like ; some for cold , some for hot , and some for temperate Air. And as for such Diseases as are produced by conceit and at distance , the cause is , the fearfulness of the Patient , which produces Irregularities in the Mind , and these occasion Irregularities in the Body , which produce such a disease , as the Mind did fearfully apprehend ; when as without that Passion and Irregularity , the Patient would , perhaps , not fall sick of that disease , But to draw towards an end , I 'le answer briefly to your Authors alledged example * * Ch. Of the Magnetick Power . which he gives of Wine , that it is troubled while the Vine flowreth : The reason , in my opinion , may perhaps be , that the Wine being the effect of the Vine , and proceeding from its stock as the producer , has not so quite alter'd Nature , as not to be sensible at all of the alteration of the Vine ; For many effects do retain the proprieties of their causes ; for example , many Children are generated , which have the same proprieties of their Parents , who do often propagate some or other vertuous or vitious qualities with their off-spring ; And this is rather a proof that there are sensitive and rational motions , and sensitive and rational knowledge in all Creatures , and so in Wine , according to the nature or propriety of its Figure ; for without motion , sense and reason , no effect could be ; nor no sympathy or antipathy . But it is to be observed , that many do mistake the true Causes , and ascribe an effect to some cause , which is no more the cause of that same effect , then a particular Creature is the cause of Nature ; and so they are apt to take the Fiddle for the hot Bricks , as if the Fiddle did make the Ass dance , when as it was the hot Bricks that did it ; for several effects may proceed from one cause , and one effect from several causes ; and so in the aforesaid example , the Wine may perhaps be disturbed by the alteration of the weather at the same time of the flowring of the Vines ; and so may Animals , as well as Vegetables , and other Creatures , alter alike at one and the same point of time , and yet none be the cause of each others alteration . And thus , to shut up my discourse , I repeat again , that sympathy and antipathy are nothing else but ordinary Passions and Appetites amongst several Creatures , which Passions are made by the rational animate Matter , and the Appetites by the sensitive , both giving such or such motions , to such or such Creatures ; for cross motions in Appetites and Passions make Antipathy , and agreeable motions in Appetites and Passions make Sympathy , although the Creatures be different , wherein these motions , Passions and Appetites are made ; and as without an object a Pattern cannot be , so without inherent or natural Passions and Appetites there can be no Sympathy or Antipathy : And there being also such Sympathy betwixt your Ladiship and me , I think my self the happiest Creature for it , and shall make it my whole study to imitate your Ladiship , and conform all my actions to the rule and pattern of yours , as becomes ,

MY opinion of Witches and Witchcraft , ( of whose Power and strange effects your Author is pleased to relate many stories ) in brief , is this ; My Sense and Reason doth inform me , that there is Natural Witchcraft , as I may call it , which is Sympathy , Antipathy , Magnetisme , and the like , which are made by the sensitive and rational motions between several Creatures , as by Imagination , Fancy , Love , Aversion , and many the like ; but these Motions , being sometimes unusual and strange to us , we not knowing their causes , ( For what Creature knows all motions in Nature , and their ways . ) do stand amazed at their working power ; and by reason we cannot assign any Natural cause for them , are apt to ascribe their effects to the Devil ; but that there should be any such devillish Witchcraft , which is made by a Covenant and Agreement with the Devil , by whose power Men do enchaunt or bewitch other Creatures , I cannot readily believe . Certainly , I dare say , that many a good , old honest woman hath been condemned innocently , and suffered death wrongfully , by the sentence of some foolish and cruel Judges , meerly upon this suspition of Witchcraft , when as really there hath been no such thing ; for many things are done by slights or juggling Arts , wherein neither the Devil nor Witches are Actors . And thus an English-man whose name was Banks , was like to be burnt beyond the Seas for a Witch , as I have been inform'd , onely for making a Horse shew tricks by Art ; There have been also several others ; as one that could vomit up several kinds of Liquors and other things : and another who did make a Drum beat of it self . But all these were nothing but slights and jugling tricks ; as also the talking and walking Bell ; and the Brazen-Head which spake these words , Time was , Time is , and Time is past , and so fell down ; Which may easily have been performed by speaking through a Pipe conveighed into the said head : But such and the like trifles will amaze many grave and wise men , when they do not know the manner or way how they are done , so as they are apt to judg them to be effected by Witchcraft or Combination with the Devil . But , as I said before , I believe there is Natural Magick ; which is , that the sensitive and rational Matter oft moves such a way , as is unknown to us ; and in the number of these is also the bleeding of a murdered body at the presence of the Murderer , which your Author a a Ch. Of the Magnetick cure of wounds . mentions ; for the corporeal motions in the murthered body may move so , as to work such effects , which are more then ordinary ; for the animal Figure , being not so quickly dissolved , the animal motions are not so soon altered , ( for the dissolving of the Figure is nothing else but an alteration of its Motions ; ) and this dissolution is not done in an instant of time , but by degrees : But yet I must confess , it is not a common action in Nature , for Nature hath both common , and singular or particular actions : As for example , Madness , natural Folly , and many the like , are but in some particular persons ; for if those actions were general , and common , then all , or most men would be either mad , or fools , but , though there are too many already , yet all men are not so ; and so some murthered bodies may bleed or express some alterations at the presence of the Murtherer , but I do not believe , that all do so ; for surely in many , not any alteration will be perceived , and others will have the same alterations without the presence of the Murtherer . And thus you see , Madam , that this is done naturally , without the help of the Devil ; nay , your Author doth himself confess it to be so ; for , says he , The act of the Witch is plainly Natural ; onely the stirring up of the vertue or power in the Witch comes from Satan . But I cannot understand what your Author means , by the departing of spiritual rays from the Witch into Man , or any other animal , which she intends to kill or hurt ; nor how Spirits wander about in the Air , and have their mansions there ; for men may talk as well of impossibilities , as of such things which are not composed of Natural Matter : If man were an Incorporeal Spirit himself , he might , perhaps , sooner conceive the essence of a Spirit , as being of the same Nature ; but as long as he is material , and composed of Natural Matter , he might as well pretend to know the Essence of God , as of an Incorporeal Spirit . Truly , I must confess , I have had some fancies oftentimes of such pure and subtil substances , purer and subtiler then the Sky or AEthereal substance is , whereof I have spoken in my Poetical Works ; but these substances , which I conceived within my fancy , were material , and had bodies , though never so small and subtil ; for I was never able to conceive a substance abstracted from all Matter , for even Fancy it self is material , and all Thoughts and Conceptions are made by the rational Matter , and so are those which Philosophers call Animal Spirits , but a material Fancy cannot produce immaterial effects , that is , Ideas of Incorporeal Spirits : And this was the cause that in the first impression of my Philosophical Opinions , I named the sensitive and rational Matter , sensitive and rational Spirits , because of its subtilty , activity and agility ; not that I thought them to be immaterial , but material Spirits : but since Spirits are commonly taken to be immaterial , and Spirit and Body are counted opposite to one another , to prevent a misapprehension in the thoughts of my Readers , as if I meant Incorporeal Spirits , I altered this expression in the last Edition , and call'd it onely sensitive and rational Matter , or , which is all one , sensitive and rational corporeal motions . You will say , perhaps , That the divine Soul in Man is a Spirit : but I desire you to call to mind what I oftentimes have told you , to wit , that when I speak of the Soul of Man , I mean onely the Natural , not the Divine Soul ; which as she is supernatural , so she acts also supernaturally ; but all the effects of the natural Soul , of which I discourse , are natural , and not divine or supernatural . But to return to Magnetisme ; I am absolutely of opinion , that it is naturally effected by natural means , without the concurrence of Immaterial Spirits either good or bad , meerly by natural corporeal sensitive and rational motions ; and , for the most part , there must be a due approach between the Agent and the Patient , or otherwise the effect will hardly follow , as you may see by the Loadstone and Iron ; Neither is the influence of the Stars performed beyond a certain distance , that is , such a distance as is beyond sight or their natural power to work ; for if their light comes to our Eyes , I know no reason against it , but their effects may come to our bodies . And as for infectious Diseases , they come by a corporeal imitation , as by touch , either of the infected air , drawn in by breath , or entring through the Pores of the Body , or of some things brought from infected places , or else by hearing ; but diseases , caused by Conceit , have their beginning , as all alterations have , from the sensitive and rational Motions , which do not onely make the fear and conceit , but also the disease ; for as a fright will sometimes cure diseases , so it will sometimes cause diseases ; but as I said , both fright , cure , and the disease , are made by the rational and sensitive corporeal motions within the body , and not by Supernatural Magick , as Satanical Witchcraft , entering from without into the body by spiritual rays . But having discoursed hereof in my former Letter , I will not trouble you with an unnecessary repetition thereof ; I conclude therefore with what I begun , viz. that I believe natural Magick to be natural corporeal motions in natural bodies : Not that I say , Nature in her self is a Magicianess , but it may be called natural Magick or Witchcraft , meerly in respect to our Ignorance ; for though Nature is old , yet she is not a Witch , but a grave , wise , methodical Matron , ordering her Infinite family , which are her several parts , with ease and facility , without needless troubles and difficulties ; for these are onely made through the ignorance of her several parts or particular Creatures , not understanding their Mistress , Nature , and her actions and government , for which they cannot be blamed ; for how should a part understand the Infinite body , when it doth not understand it self ; but Nature understands her parts better , then they do her . And so leaving Wise Nature , and the Ignorance of her Particulars , I understand my self so far , that I am ,

I Am not of your Authors * * In his Treatise of Time . opinion , That Time hath no relation to Motion , but that Time and Motion are as unlike and different from each other as Finite from Infinite , and that it hath its own essence or being Immoveable , Vnchangeable , Individable , and unmixed with things , nay , that Time is plainly the same with Eternity . For , in my opinion , there can be no such thing as Time in Nature , but what Man calls Time , is onely the variation of natural motions ; wherefore Time , and the alteration of motion , is one and the same thing under two different names ; and as Matter , Figure , and Motion , are inseparable , so is Time inseparably united , or rather the same thing with them , and not a thing subsisting by it self ; and as long as Matter , Motion and Figure have been existent , so long hath Time ; and as long as they last , so long doth Time . But when I say , Time is the variation of motion , I do not mean the motion of the Sun or Moon , which makes Days , Months , Years , but the general motions or actions of Nature , which are the ground of Time ; for were there no Motion , there would be no Time ; and since Matter is dividable , and in parts , Time is so too ; neither hath Time any other Relation to Duration , then what Nature her self hath . Wherefore your Author is mistaken , when he says , Motion is made in Time , for Motion makes Time , or rather is one and the same with Time ; and Succession is no more a stranger to Motion , then Motion is to Nature , as being the action of Nature , which is the Eternal servant of God . But , says he , Certain Fluxes of Formerlinesses and Laternesses , have respect unto frail moveable things in their motions , wherewith they hasten unto the appointed ends of their period , and so unto their own death or destruction ; but what relation hath all that to Time : for therefore also ought Time to run with all and every motion ? Verily so there should be as many times and durations as there are motions . I answer : To my Reason , there are as many times and durations as there are motions ; for neither time nor duration can be separated from motion , no more then motion can be separated from them , being all one . But Time is not Eternity , for Eternity hath no change , although your Author makes Time and Eternity all one , and a being or substance by it self : Yet I will rather believe Solomon ' , then him , who says , that there is a time to be merry , and a time to be sad ; a time to mourn , and a time to rejoyce , and so forth : making so many divisions of Time as there are natural actions ; whenas your Author makes natural actions strangers to Nature , dividing them from their substances : Which seemeth very improbable in the opinion of ,

YOur Authors a a Of the disease of the Stone , Ch. 9. opinion is , That a bright burning Iron doth not burn a dead Carcass after an equal manner as it doth a live one ; For in live bodies , saith he , it primarily burts the sensitive Soul , the which therefore being impatient , rages after a wonderful manner , doth by degrees resolve and exasperate its own and vital liquors into a sharp poyson , and then contracts the fibres of the flesh , and turns them into an escharre , yea , into the way of a coal ; but a dead Carcass is burnt by bright burning Iron , no otherwise , then if Wood , or if any other unsensitive thing should be ; that is , it burns by a proper action of the fire , but not of the life . To which opinion , I answer : That my Reason cannot conceive any thing to be without life , and so neither without sense ; for whatsoever hath self-motion , has sense and life ; and that self-motion is in every Creature , is sufficiently discoursed of in my former Letters , and in my Philosophical Opinions ; for self-motion , sense , life , and reason , are the grounds and principles of Nature , without which no Creature could subsist . I do not say , That there is no difference between the life of a dead Carcass , and a live one , for there is a difference between the lives of every Creature ; but to differ in the manner of life , and to have neither life nor sense at all , are quite different things : But your Author affirms himself , that all things have a certain sense of feeling , when he speaks of Sympathy and Magnetisme , and yet he denies that they have life : And others again , do grant life to some Creatures , as to Vegetables , and not sense . Thus they vary in their Opinions , and divide sense , life , and motion , when all is but one and the same thing ; for no life is without sense and motion , nor no motion without sense and life ; nay , not without Reason ; for the chief Architect of all Creatures , is sensitive and rational Matter . But the mistake is , that-most men , do not , or will not conceive , that there is a difference and variety of the corporeal sensitive and rational motions in every Creature ; but they imagine , that if all Creatures should have life , sense , and reason , they must of necessity have all alike the same motions , without any difference ; and because they do not perceive the animal motions in a Stone or Tree , they are apt to deny to them all life , sense , and motion . Truly , Madam , I think no man will be so mad , or irrational , as to say a Stone is an Animal , or an Animal is a Tree , because a Stone and Tree have sense , life , and motion ; for every body knows , that their Natural figures are different , and if their Natures be different , then they cannot have the same Motions , for the corporeal motions do make the nature of every particular Creature , and their differences ; and as the corporeal motions act , work , or move , so is the nature of every figure , Wherefore , no body , I hope , will count me so senseless , that I believe sense and life to be after the like manner in every particular Creature or part of Nature ; as for example , that a Stone or Tree has animal motions , and doth see , touch , taste , smell and hear by such sensitive organs as an Animal doth ; but , my opinion is , that all Sense is not bound up to the sensitive organs of an Animal , nor Reason to the kernel of a man's brain , or the orifice of the stomack , or the fourth ventricle of the brain , or onely to a mans body ; for though we do not see all Creatures move in that manner as Man or Animals do , as to walk , run , leap , ride , &c. and perform exterior acts by various local motions ; nevertheless , we cannot in reason say , they are void and destitute of all motion ; For what man knows the variety of motions in Nature : Do not we see , that Nature is active in every thing , yea , the least of her Creatures . For example ; how some things do unanimously conspire and agree , others antipathetically flee from each other ; and how some do increase , others decrease ; some dissolve , some consist , and how all things are subject to perpetual changes and alterations ; and do you think all this is done without motion , life , sense , and reason ? I pray you consider , Madam , that there are internal motions as well as external , alterative as well as constitutive ; and several other sorts of motions not perceptible by our senses , and therefore it is impossible that all Creatures should move after one sort of motions . But you will say , Motion may be granted , but not Life , Sense , and Reason . I answer , I would fain know the reason why not ; for I am confident that no man can in truth affirm the contrary : What is Life , but sensitive Motion ? what is Reason , but rational motion ? and do you think , Madam , that any thing can move it self without life , sense and reason ? I , for my part , cannot imagine it should ; for it would neither know why , whither , nor what way , or how to move . But you may reply , Motion may be granted , but not self-motion ; and life , sense , and reason , do consist in self-motion . I answer : this is imposible ; for not any thing in Nature can move naturally without natural motion , and all natural motion is self-motion . If you say it may be moved by another ; My answer is , first , that if a thing has no motion in it self , but is moved by another which has self-motion , then it must give that immovable body motion of its own , or else it could not move , having no motion at all ; for it must move by the power of motion , which is certain ; and then it must move either by its own motion , or by a communicated or imparted motion ; if by a communicated motion , then the self-moveable thing or body must transfer its own motion into the immoveable , and lose so much of its own motion as it gives away , which is impossible , as I have declared heretofore at large , unless it do also transfer its moving parts together with it , for motion cannot be transfered without substance . But experience and observation witnesseth the contrary . Next , I say , if it were possible that one body did move another , then most part of natural Creatures , which are counted immoveable of themselves , or inanimate , and destitute of self-motion , must be moved by a forced or violent , and not by a natural motion ; for all motion that proceeds from an external agent or moving power , is not natural , but forced , onely self-motion is natural ; and then one thing moving another in this manner , we must at last proceed to such a thing whch is not moved by another , but hath motion in it self , and moves all others ; and , perhaps , since man , and the rest of animals have self-motion , it might be said , that the motions of all other inanimate Creatures , as they call them , doth proceed from them ; but man being so proud , ambitious , and self-conceited , would soon exclude all other animals , and adscribe this power onely to himself , especially since he thinks himself onely endued with Reason , and to have this prerogative above all the rest , as to be the sole rational Creature in the World . Thus you see , Madam , what confusion , absurdity , and constrained work will follow from the opinion of denying self-motion , and so consequently , life and sense to natural Creatures . But I , having made too long a digresion , will return to your Authors discourse : And as for that he says , A dead Carcass burns by the proper action of the fire , I answer , That if the dissolving motions of the fire be too strong for the consistent motions of that body which fire works upon , then fire is the cause of its alteration ; but if the consistent motions of the body be too strong for the dissolving motions of the fire , then the fire can make no alteration in it . Again : he says , Calx vive , as long as it remains dry , it gnaws not a dead Carcass ; but it presently gnaws live flesh , and makes an escharre ; and a dead carcass is by lime wholly resolved into a liquor , and is combibed , except the bone and gristle thereof ; but it doth not consume live flesh into a liquor , but translates it into an escharre . I will say no more to this , but that I have fully enough declared my opinion before , that the actions or motions of life alter in that which is named a dead Carcass , from what they were in that which is called a Living body ; but although the actions of Life alter , yet life is not gone or annihilated ; for life is life , and remains still the same , but the actions or motions of life change and differ in every figure ; and this is the cause that the actions of Fire , Time , and Calx-vive , have not the same effects in a dead Carcass , as in a living Body ; for the difference of their figures , and their different motions , produce different effects in them ; and this is the cause , that one and the same fire doth not burn or act upon all bodies alike : for some it dissolves , and some not ; and some it hardens , and some it consumes ; and some later , some sooner : For put things of several natures into the same Fire , and you will see how they will burn , or how fire will act upon them after several manners ; so that fire cannot alter the actions of several bodies to its own blas ; and therefore , since a living and a dead Body ( as they call them ) are not the same , ( for the actions or motions of life , by their change or alteration , have altered the nature or figure of the body ) the effects cannot be the same ; for a Carcass has neither the interior nor exterior motions of that figure which it was before it was a Carcass , and so the figure is quite alter'd from what it was , by the change and alteration of the motions . But to conclude , the motions of the exterior Agent , and the motions of the Patient , do sometimes joyn and unite , as in one action , or to one effect , and sometimes the motions of the Agent are onely an occasion , but not a co-workman in the production of such or such an effect , as the motions of the Patient do work ; neither can the motions of the Agent work totally and meerly of themselves , such or such effects , without the assistance or concurrence of the motions of the Patient , but the motions of the Patient can : and there is nothing that can prove more evidently that Matter moves it self , and that exterior agents or bodies are onely an occasion to such or such a motion in another body , then to see how several things put into one and the same fire , do alter after several modes ; which shews , it is not the onely action of fire , but the interior motions of the body thrown into the fire , which do alter its exterior form or figure . And thus , I think I have said enough to make my opinions clear , that they may be the better understood : which is the onely aim and desire of ,

YOur Author is not a Natural , but a Divine Philosopher , for in many places he undertakes to interpret the Scripture ; wherein , to my judgment , he expresseth very strange opinions ; you will give me leave at this present to note some few . First , in one place , a a Ch. The Position is demonstrated . interpreting that passage of Scripture , b b Gen. 6. 2. where it is said , That the sons of God took to wives the daughters of men : He understands by the Sons of God , those which came from the Posterity of Adam , begotten of a Man and a Woman , having the true Image of God : But by the Daughters of Men , he understands Monsters ; that is , those which through the Devils mediation , were conceived in the womb of a Junior Witch or Sorceress : For when Satan could find no other ways to deprive all the race of Men of the Image of God , and extinguish the Immortal mind out of the stock of Adams Posterity , he stirr'd up detestable copulations , from whence proceeded savage Monsters , as Faunes , Satyrs , Sylphs , Gnomes , Nymphs , Driades , Najades , Nereides , &c. which generated their off-springs amongst themselves , and their posterities again contracted their copulations amongst themselves , and at length began Wedlocks with Men ; and from this copulation of Monsters and Nymphs , they generated strong Gyants . Which Interpretation , how it agrees with the Truth of Scripture , I will leave to Divines to judg : But , for my part , I cannot conceive , how , or by what means or ways , those Monsters and Nymphs were produced or generated . Next , his opinion is , That Adam did ravish Eve , and defloured her by force , calling him the first infringer of modesty , and deflourer of a Virgin ; and that therefore God let hair grow upon his chin , cheeks , and lips , that he might be a Compere , Companion , and like unto many four-footed Beasts , and might bear before him the signature of the same ; and that , as he was lecherous after their manner , he might also shew a rough countenance by his hairs : which whether it be so , or not , I cannot tell , neither do I think your Author can certainly know it himself ; for the Scripture makes no mention of it : But this I dare say , that Eves Daughters prove rather the contrary , viz. that their Grandmother did freely consent to their Grandfather . Also he says , That God had purposed to generate Man by the overshadowing of the Holy Spirit , but Man perverted the Intent of God ; for had Adam not sinned , there had been no generation by the copulation of a Man and Woman , but all the off-springs had appear'd out of Eve , a Virgin , from the Holy Spirit , as conceived from God , and born of a woman , a virgin , To which , I answer , first , That it is impossible to know the Designs and secret Purposes of God : Next , to make the Holy Spirit the common Generator of all Man-kind , is more then the Scripture expresses , and any man ought to say : Lastly , it is absurd , in my opinion , to say , that frail and mortal Men , can pervert the intent and designs of the Great God ; or that the Devil is able to prevent God's Intent , ( as his expression is in the same place . ) But your Author shews a great affectioin to the Female Sex , when he says , that God doth love Women before Men , and that he has given them a free gift of devotion before men ; when as others do lay all the fault upon the Woman , that she did seduce the Man ; however in expressing his affection for Women , your Author expresses a partiality in God . And , as for his opinion , that God creates more Daughters then Males , and that more Males are extinguished by Diseases , Travels , Wars , Duels , Shipwracks , and the like : Truly , I am of the same mind , that more Men are kill'd by Travels , Wars , Duels , Shipwracks , &c. then Women ; for Women never undergo these dangers , neither do so many kill themselves with intemperate Drinking , as Men do ; but yet I believe , that Death is as general , and not more favourable to Women , then he is to Men ; for though Women be not slain in Wars like Men , ( although many are , by the cruelty of Men , who not regarding the weakness of their sex , do inhumanely kill them , ) yet many do die in Child-bed , which is a Punishment onely concerning the Female sex . But to go on in your Authors Interpretations : His knowledg of the Conception of the Blessed Virgin , reaches so far , as he doth not stick to describe exactly , not onely how the blessed Virgin conceiv'd in the womb , but first in the heart , or the sheath of the heart ; and then how the conception removed from the heart , into the womb , and in what manner it was performed . Certainly , Madam , I am amazed , when I see men so conceited with their own perfections and abilities , ( I may rather say , with their imperfections and weaknesses ) as to make themselves God's privy Councellors , and his Companions , and partakers of all the sacred Mysteries , Designs , and hidden secrets of the Incomprehensible and Infinite God . O the vain Presumption , Pride , and Ambition of wretched Men ! There are many more such expressions in your Authors works , which , in my opinion , do rather detract from the Greatness of the Omnipotent God , then manifest his Glory : As for example ; That Man is the clothing of the Deity , and the sheath of the Kingdom of God , and many the like : which do not belong to God ; for God is beyond all expression , because he is Infinite ; and when we name God , we name an Unexpressible , and Incomprehensible Being ; and yet we think we honour God , when we express him after the manner of corporeal Creatures . Surely , the noblest Creature that ever is in the World , is not able to be compared to the most Glorious God , but whatsoever comparison is made , detracts from his Glory : And this , in my opinion , is the reason , that God forbad any likeness to be made of him , either in Heaven , or upon Earth , because he exceeds all that we might compare or liken to him . And as men ought to have a care of such similizing expressions , so they ought to be careful in making Interpretations of the Scripture , and expressing more then the Scripture informs ; for what is beyond the Scripture , is Man 's own fancy ; and to regulate the Word of God after Man's fancy , at least to make his fancy equal with the Word of God , is Irreligious . Wherefore , men ought to submit , and not to pretend to the knowledg of God's Counsels and Designs , above what he himself hath been pleased to reveal : as for example , to describe of what Figure God is , and to comment and descant upon the Articles of Faith ; as how Man was Created ; and what he did in the state of Innocence ; how he did fall ; and what he did after his fall : and so upon the rest of the Articles of our Creed , more then the Scripture expresses , or is conformable to it . For if we do this , we shall make a Romance of the holy Scripture , with our Paraphrastical Descriptions : which alas ! is too common already . The truth is , Natural Philosophers , should onely contain themselves within the sphere of Nature , and not trespass upon the Revelation of the Scripture , but leave this Profession to those to whom it properly belongs . I am confident , a Physician , or any other man of a certain Profesion , would not take it well , if others , who are not professed in that Art , should take upon them to practise the same : And I do wonder , why every body is so forward to encroach upon the holy Profession of Divines , which yet is a greater presumption , then if they did it upon any other ; for it contains not onely a most hidden and mystical knowledg , as treating of the Highest Subject , which is the most Glorious , and Incomprehensible God , and the salvation of our Souls ; but it is also most dangerous , if not interpreted according to the Holy Spirit , but to the byass of man's fancy . Wherefore , Madam , I am afraid to meddle with Divinity in the least thing , lest I incur the hazard of offending the divine Truth , and spoil the excellent Art of Philosophying ; for a Philosophical Liberty , and a Supernatural Faith , are two different things , and suffer no co-mixture ; as I have declared sufficiently heretofore . And this you will find as much truth , as that I am ,

ALthough your Author a a Ch. Of the Image of the Mind . is of the opinion of Plato , in making Three sorts of Atheists : One that believes no Gods ; Another , which indeed admits of Gods , yet such as are uncarefull of us , and despisers of small matters , and therefore also ignorant of us : And lastly , a third sort , which although they believe the Gods to be expert in the least matters , yet do suppose that they are flexible and indulgent toward the smallest cold Prayers or Petitions : Yet I cannot approve of this distinction , for I do understand but one sort of Atheists ; that is , those which believe no God at all ; but those which believe that there is a God , although they do not worship him truly , nor live piously and religiously as they ought , cannot , in truth , be called Atheists , or else there would be innumerous sorts of Atheists ; to wit , all those , that are either no Christians , or not of this or that opinion in Christian Religion , besides all them that live wickedly , impiously and irreligiously ; for to know , and be convinced in his reason , that there is a God , and to worship him truly , according to his holy Precepts and Commands ; are two several things : And as for the first , that is , for the Rational knowledge of the Existence of God , I cannot be perswaded to believe , there is any man which has sense and reason , that doth not acknowledg a God ; nay , I am sure , there is no part of Nature which is void and destitute of this knowledg of the Existence of an Infinite , Eternal , Immortal , and Incomprehensible Deity ; for every Creature , being indued with sense and reason , and with sensitive and rational knowledg , there can no knowledg be more Universal then the knowledg of a God , as being the root of all knowledg : And as all Creatures have a natural knowledg of the Infinite God , so , it is probable , they Worship , Adore , and Praise his Infinite Power and Bounty , each after its own manner , and according to its nature ; for I cannot believe , God should make so many kinds of Creatures , and not be worshipped and adored but onely by Man : Nature is God's Servant , and she knows God better then any Particular Creature ; but Nature is an Infinite Body , consisting of Infinite Parts , and if she adores and worships God , her Infinite Parts , which are Natural Creatures , must of necessity do the like , each according to the knowledg it hath : but Man in this particular goes beyond others , as having not onely a natural , but also a revealed knowledg of the most Holy God ; for he knows Gods Will , not onely by the light of Nature , but also by revelation , and so more then other Creatures do , whose knowledg of God is meerly Natural . But this Revealed Knowledg makes most men so presumptuous , that they will not be content with it , but search more and more into the hidden mysteries of the Incomprehensible Deity , and pretend to know God as perfectly , almost , as themselves ; describing his Nature and Essence , his Attributes , his Counsels , his Actions , according to the revelation of God , ( as they pretend ) when as it is according to their own Fancies . So proud and presumptuous are many : But they shew thereby rather their weaknesses and follies , then any truth ; and all their strict and narrow pryings into the secrets of God , are rather unprofitable , vain and impious , then that they should benefit either themselves , or their neighbour ; for do all we can , God will not be perfectly known by any Creature : The truth is , it is a meer impossibility for a finite Creature , to have a perfect Idea of an Infinite Being , as God is ; be his Reason never so acute or sharp , yet he cannot penetrate what is Impenetrable , nor comprehend what is Incomprehensible : Wherefore , in my opinion , the best way is humbly to adore what we cannot conceive , and believe as much as God has been pleased to reveal , without any further search ; lest we diving too deep , be swallowed up in the bottomless depth of his Infiniteness : Which I wish every one may observe , for the benefit of his own self , and of others , to spend his time in more profitable Studies , then vainly to seek for what cannot be found . And with this hearty wish I conclude , resting ,

YOur Author is so much for Spirits , that he doth not stick to affirm , a a Ch. Of the Magnetick cure of wounds . That Bodies scarce make up a moity or half part of the world ; but Spirits , even by themselves , have or possess their moity , and indeed the whole world . If he mean bodiless and incorporeal Spirits , I cannot conceive how Spirits can take up any place , for place belongs onely to body , or a corporeal substance , and millions of immaterial Spirits , nay , were their number infinite , cannot possess so much place as a small Pinspoint , for Incorporeal Spirits possess no place at all : which is the reason , that an Immaterial and a Material Infinite cannot hinder , oppose , or obstruct each other ; and such an Infinite , Immaterial Spirit is God alone . But as for Created Immaterial Spirits , as they call them , it may be questioned whether they be Immaterial , or not ; for there may be material Spirits as well as immaterial , that is , such pure , subtil and agil substances as cannot be subject to any humane sense , which may be purer and subtiller then the most refined air , or purest light ; I call them material spirits , onely for distinctions sake , although it is more proper , to call them material substances : But be it , that there are Immaterial Spirits , yet they are not natural , but supernatural ; that is , not substantial parts of Nature ; for Nature is material , or corporeal , and so are all her Creatures , and whatsoever is not material is no part of Nature , neither doth it belong any ways to Nature : Wherefore , all that is called Immaterial , is a Natural Nothing , and an Immaterial Natural substance , in my opinion , is non-sense : And if you contend with me , that Created Spirits , as good and bad Angels , as also the Immortal Mind of Man , are Immaterial , then I say they are Supernatural ; but if you say , they are Natural , then I answer they are Material : and thus I do not deny the existence of Immaterial Spirits , but onely that they are not parts of Nature , but supernatural ; for there may be many things above Nature , and so above a natural Understanding , and Knowledg , which may nevertheless have their being and existence , although they be not Natural , that is , parts of Nature : Neither do I deny that those supernatural Creatures may be amongst natural Creatures , that is , have their subsistence amongst them , and in Nature ; but they are not so commixed with them , as the several parts of Matter are , that is , they do not joyn to the constitution of a material Creature ; for no Immaterial can make a Material , or contribute any thing to the making or production of it ; but such a co-mixture would breed a meer confusion in Nature : wherefore , it is quite another thing , to be in Nature , or to have its subsistence amongst natural Creatures in a supernatural manner or way , and to be a part of Nature . I allow the first to Immaterial Spirits , but not the second , viz. to be parts of Nature . But what Immaterial Spirits are , both in their Essence or Nature , and their Essential Properties , it being supernatural , and above natural Reason , I cannot determine any thing thereof . Neither dare I say , they are Spirits like as God is , that is , of the same Essence or Nature , no more then I dare say or think that God is of a humane shape or figure , or that the Nature of God is as easie to be known as any notion else whatsoever , and that we may know as much of him as of any thing else in the world . For if this were so , man would know God as well as he knows himself ; but God and his Attributes are not so easily known as man may know himself and his own natural Proprieties ; for God and his Attributes are not conceiveable or comprehensible by any humane understanding , which is not onely material , but also finite ; for though the parts of Nature be infinite in number , yet each is finite in it self , that is , in its figure , and therefore no natural Creature is capable to conceive what God is ; for he being infinite , there is also required an infinite capacity to conceive him ; Nay , Nature her self , although she is Infinite , yet cannot possibly have an exact notion of God , by reason she is Material , and God is Immaterial ; and if the Infinite servant of God is not able to conceive God , much less will a finite part of Nature do it . Besides , the holy Church doth openly confess and declare the Incomprehensibility of God , when in the Athanasian Creed , she expresses , that the Father is Incomprehensible , the Son Incomprehensible , and the Holy Ghost Incomprehensible , and that there are not three , but one Incomprehensible God : Therefore , if any one will prove the contrary , to wit , that God is Comprehensible , or ( which is all one ) that God is as easie to be known as any Creature whatsoever , he surely is more then the Church : But I shall never say or believe so , but rather confess my ignorance , then betray my folly ; and leave things Divine to the Church ; to which I submit , as I ought , in all Duty : and as I do not meddle with any Divine Mysteries , but subject my self , concerning my Faith or Belief , and the regulating of my actions for the obtaining of Eternal Life , wholly under the government and doctrine of the Church , so , I hope , they will also grant me leave to have my liberty concerning the contemplation of Nature and natural things , that I may discourse of them , with such freedom , as meer natural Philosophers use , or at least ought , to do ; and thus I shall be both a good Chistian , and a good Natural Philosopher : Unto which , to make the number perfect , I will add a third , which is , I shall be ,

THough I am loth ( as I have often told you ) to imbarque my self in the discourse of such a subject , as no body is able naturally to know , which is the supernatural and divine Soul in Man ; yet your Author having , in my judgment , strange opinions , both of the Essence , Figure , Seat and Production of the Soul , and discoursing thereof , with such liberty and freedom , as of any other natural Creature , I cannot chuse but take some notice of his discourse , and make some reflections upon it ; which yet , shall rather express my ignorance of the same subject , then in a positive answer , declare my opinion thereof ; for , in things divine , I refer my self wholly to the Church , and submit onely to their instructions , without any further search of natural reason ; and if I should chance to express more then I ought to do , and commit some errror , it being out of ignorance rather then set purpose , I shall be ready upon better information , to mend it , and willingly subject my self under the censure and correction of the holy Church , as counting it no disgrace to be ignorant in the mysteries of Faith , since Faith is of things unknown , but rather a duty required from every Lay-man to believe simply the Word of God , as it is explained and declared by the Orthodox Church , without making Interpretations out of his own brain , and according to his own fancy , which breeds but Schismes , Heresies , Sects , and Confusions . But concerning your Author , I perceive by him , first , that he makes no distinction between the Natural or Rational Soul or Mind of Man , and between the Divine or Supernatural Soul , but takes them both as one , and distinguishes onely the Immortal Soul from the sensitive Life of Man , which he calls the Frail , Mortal , Sensitive Soul . Next , all his knowledg of this Immortal Soul is grounded upon Dreams and Visions , and therefore it is no wonder , if his opinions be somewhat strange and irregular . I saw , in a Vision , says he , a a Ch. Of the Image of the Mind . my Mind in a humane shape ; but there was a light , whose whole homogeneal body was actively seeing , a spiritual substance , Chrystalline , shining with a proper splendor , or a splendor of its own , but in another cloudy part it was rouled up as it were in the husk of it self ; which whether it had any splendor of it self , I could not discern , by reason of the superlative brightness of the Chrystal Spirit contain'd within . Whereupon he defines the Soul to be a Spirit , beloved of God , homogeneal , simple , immortal , created into the Image of God , one onely Being , whereto death adds nothing , or takes nothing from it , which may be natural or proper to it in the Essence of its simplicity . As for this definition of the Soul , it may be true , for any thing I know : but when your Author makes the divine Soul to be a Light , I cannot conceive how that can agree ; for Light is a Natural and Visible Creature , and , in my opinion , a corporeal substance ; whereas the Soul is immaterial and incorporeal : But be it , that Light is not a substance , but a neutral Creature , according to your Author ; then , nevertheless the Immortal Soul cannot be said to be a light , because she is a substance . He may say , a a Of the Spirit of life . The Soul is an Incomprehensible Light . But if the Soul be Incomprehensible , how then doth he know that she is a light , and not onely a light , but a glorious and splendorous light ? You will say , By a Dream , or Vision . Truly , Madam , to judg any thing by a Dream , is a sign of a weak judgment . Nay , since your Author calls the soul constantly a light ; if it were so , and that it were such a splendorous , bright and shining light , as he says ; then when the body dies , and the soul leaves its Mansion , it would certainly be seen , when it issues out of the body . But your Author calls the Soul a Spiritual Substance , and yet he says , she has an homogeneal body , actively seeing and shining with a proper splendor of her own ; which how it can agree , I leave to you to judg ; for I thought , an Immaterial spirit and a body were too opposite things , and now I see , your Author makes Material and Immaterial , Spiritual and Corporeal , all one . But this is not enough , but he allows it a Figure too , and that of a human shape ; for says he , I could never consider the Thingliness of the Immortal Mind with an Individual existence , deprived of all figure , neither but that it at least would answer to a human shape ; but the Scripture , as much as is known to me , never doth express any such thing of the Immortal Soul , and I should be loth to believe any more thereof then it declares . The Apostles , although they were conversant with Christ , and might have known it better , yet were never so inquisitive into the nature of the Soul , as our Modern divine Philosophers are ; for our Saviour , and they , regarded more the salvation of Man's Soul , and gave holy and wise Instructions rather , how to live piously and conformably to God's Will , to gain eternal Life , then that they should discourse either of the Essence or Figure , or Proprieties of the Soul , and whether it was a light , or any thing else , and such like needless questions , raised in after-times onely by the curiosity of divine Philosophers , or Philosophying Divines ; For though Light is a glorious Creature , yet Darkness is as well a Creature as Light , and ought not therefore to be despised ; for if it be not so bright , and shining as Light , yet it is a grave Matron-like Creature , and very useful : Neither is the Earth , which is inwardly dark , to be despised , because the Sun is bright . The like may be said of the soul , and of the body ; for the body is very useful to the soul , how dark soever your Author believes it to be ; and if he had not seen light with his bodily eyes , he could never have conceived the Soul to be a Light : Wherefore your Author can have no more knowledg of the divine soul then other men have , although he has had more Dreams and Visions ; nay , he himself confesses , that the Soul is an Incomprehensible Light ; which if so , she cannot be perfectly known , nor confined to any certain figure ; for a figure or shape belongs onely to a corporeal substance , and not to an incorporeal : and so , God being an Incomprehensible Being , is excluded from all figure , when as yet your Author doth not stick to affirm , that God is of a humane figure too , as well as the humane Soul is ; For , says he , Since God hath been pleased to adopt the Mind alone into his own Image , it also seems to follow , that the vast and unutter able God is of a humane Figure , and that from an argument from the effect , if there be any force of arguments in this subject . Oh! the audacious curiosity of Man ! Is it not blasphemy to make the Infinite God of a frail and humane shape , and to compare the most Holy to a sinful Creature ? Nay , is it not an absurdity , to confine and inclose that Incomprehensible Being in a finite figure ? I dare not insist longer upon this discourse , lest I defile my thoughts with the entertaining of such a subject that derogates from the glory of the Omnipotent Creator ; Wherefore , I will hasten , as much as I can , to the seat of the Soul , which , after relating several opinions , your Author concludes to be the orifice of the stomack , where the Immortal Soul is involved and entertained in the radical Inn or Bride-bed of the sensitive Soul or vital Light ; which part of the body is surely more honoured then all the rest : But I , for my part , cannot conceive why the Soul should not dwell in the parts of conception , as well , as in the parts of digestion , except it be to prove her a good Huswife ; however , your Author allows her to slide down sometimes : For , The action of the Mind , says he , being imprisoned in the Body , doth always tend downwards ; but whether the Soul tend more downwards then upwards , Contemplative Persons , especially Scholars , and grave States-men , do know best ; certainly , I believe , they find the soul more in their heads then in their heels , at least her operations . But , to conclude , if the Soul be pure and single of her self , she cannot mix with the Body , because she needs no assistance ; nor joyn with the Body , though she lives in the Body , for she needs no support ; and if she be individable , she cannot divide her self into several Parts of the Body ; but if the Soul spread over all the Body , then she is bigger , or less , according as the Body is ; and if she be onely placed in some particular part , then onely that one part is indued with a Soul , and the rest is Soul-less ; and if she move from place to place , then some parts of the Body will be sometimes indued with a Soul , sometimes not ; and if any one part requires not the subsistence of the Soul within it , then perhaps all the Body might have been able to spare her ; neither might the Soul , being able to subsist without the body , have had need of it . Thus useless questions will trouble men's brains , if they give their fancies leave to work . I should add something of the Production of the Soul ; but being tyred with so tedious a discouse of your Author , I am not able to write any more , but repose my Pen , and in the mean while rest affectionately ,

XXIII . MADAM ,

YOur Authors comparison a a Of the seat of the Soul . It. Of the Image of the Mind . of the Sun , with the immaterial or divine Soul in Man , makes me almost of opinion , that the Sun is the Soul of this World we inhabit , and that the fixed Stars , which are counted Suns by some , may be souls to some other worlds ; for every one man has but one immaterial or divine soul , which is said to be individable and simple in its essence , and therefore unchangeable ; and if the Sun be like this immaterial soul , then the Moon may be like the material soul. But as for the Production of this immaterial and divine Soul in Man , whether it come by an immediate Creation from God , or be derived by a successive propagation from Parents upon their Children , I cannot determine any thing , being supernatural , and not belonging to my study ; nevertheless , the Propagation from Parents seems improbable to my reason ; for I am not capable to imagine , how an immaterial soul , being individable , should beget another . Some may say , by imprinting or sealing , viz. that the soul doth print the Image of its own figure upon the spirit of the seed ; which if so , then first there will onely be a production of the figure of the soul , but not of the substance , and so the Child will have but the Image of the soul , and not a real and substantial soul. Secondly , Every Child of the same Parents would be just alike , without any distinguishment ; if not in body , yet in the Faculties and Proprieties of their Minds or Souls . Thirdly , There must be two prints of the two souls of both Parents upon one Creature , to wit , the Child ; for both Parents do contribute alike to the Production of the Child , and then the Child would either have two souls , or both must be joyned as into one ; which how it can be , I am not able to conceive . Fourthly , If the Parents print the Image of their souls upon the Child , then the Childs soul bears not the Image of God , but the Image of Man , to wit , his Parents . Lastly , I cannot understand , how an immaterial substance should make a print upon a corporeal substance , for Printing is a corporeal action , and belongs onely to bodies . Others may say , that the soul is from the Parents transmitted into the Child , like as a beam of Light ; but then the souls of the Parents must part with some of their own substance ; for light is a substance dividable , in my opinion ; and if it were not , yet the soul is a substance , and cannot be communicated without losing some of his own substance , but that is impossible ; for the immaterial soul being individable , cannot be diminished nor increased in its substance or Nature . Others again , will have the soul produced by certain Ideas ; but Ideas being corporeal , cannot produce a substance Incorporeal or Spiritual . Wherefore I cannot conceive how the souls of the Parents , being individable in themselves , and not removeable out of their bodies until the time of death , should commix so , as to produce a third immaterial soul , like to their own . You will say , As the Sun , which is the fountain of heat and light , heats and enlightens , and produces other Creatures . But I answer , The Sun doth not produce other Suns , at least not to our knowledg . 'T is true , there are various and several manners and ways of Productions , but they are all natural , that is , material , or corporeal ; to wit , Productions of some material beings , or corporeal substances ; but the immaterial soul not being in the number of these , it is not probable , that she is produced by the way of corporeal productions , but created and infused from God , according to her nature , which is supernatural and divine : But being the Image of God , how she can be defiled with the impurity of sin , and suffer eternal damnation for her wickedness , without any prejudice to her Creator , I leave to the Church to inform us thereof . Onely one Question I will add , Whether the Soul be subject to Sickness and Pain ? To which I answer : As for the supernatural and divine Soul , although she be a substance , yet being not corporeal , but spiritual , she can never suffer pain , sickness , nor death ; but as for the natural soul , to speak properly , there is no such thing in Nature as pain , sickness , or death ; unless in respect to some Particular Creatures composed of natural Matter ; for what Man calls Sickness , Pain , and Death , are nothing else but the Motions of Nature ; for though there is but one onely Matter , that is , nothing but meer Matter in Nature , without any co-mixture of either a spiritual substance , or any thing else that is not Matter ; yet this meer Matter is of several degrees and parts , and is the body of Nature ; Besides , as there is but one onely Matter , so there is also but one onely Motion in Nature , as I may call it , that is , meer corporeal Motion , without any rest or cessation , which is the soul of that Natural body , both being infinite ; but yet this onely corporeal Motion is infinitely various in its degrees or manners , and ways of moving ; for it is nothing else but the action of natural Matter , which action must needs be infinite , being the action of an infinite body , making infinite figures and parts . These motions and actions of Nature , since they are so infinitely various , when men chance to observe some of their variety , they call them by some proper name , to make a distinguishment , especially those motions which belong to the figure of their own kind ; and therefore when they will express the motions of dissolution of their own figure , they call them Death ; when they will express the motions of Production of their figure , they call them Conception and Generation ; when they will express the motions proper for the Consistence , Continuance and Perfection of their Figure , they call them Health ; but when they will express the motions contrary to these , they call them Sickness , Pain , Death , and the like : and hence comes also the difference between regular and irregular motions ; for all those Motions that belong to the particular nature and consistence of any figure , they call regular , and those which are contrary to them , they call irregular . And thus you see , Madam , that there is no such thing in Nature , as Death , Sickness , Pain , Health , &c. but onely a variety and change of the corporeal motions , and that those words express nothing else but the variety of motions in Nature ; for men are apt to make more distinctions then Nature doth : Nature knows of nothing else but of corporeal figurative Motions , when as men make a thousand distinctions of one thing , and confound and entangle themselves so , with Beings , Non-beings , and Neutral-beings , Corporeals and Incorporeals , Substances and Accidents , or manners and modes of Substances , new Creations , and Annihilations , and the like , as neither they themselves , nor any body else , is able to make any sense thereof ; for they are like the tricks and slights of Juglers , 't is here , 't is gone ; and amongst those Authors which I have read as yet , the most difficult to be understood is this Author which I am now perusing , who runs such divisions , and cuts Nature into so small Parts , as the sight of my Reason is not sharp enough to discern them . Wherefore I will leave them to those that are more quick-sighted then I , and rest ,

YOur Author relates , how by some the Immortal Soul Ch. Of the Image of the Soul . is divided into two distinct parts ; the Inferior or more outward , which by a peculiar name is called the Soul , and the other the Superior , the more inward , the which is called the bottom of the Soul or Spirit , in which Part the Image of God is specially contained ; unto which is no access for the Devil , because there is the Kingdom of God : and each part has distinct Acts , Proprieties , and Faculties . Truly , Madam , I wonder , how some men dare discourse so boldly of the Soul , without any ground either of Scripture or Reason , nay , with such contradiction to themselves , or their own opinions ; For how can that be severed into parts , which in its nature is Individable ? and how can the Image of God concern but one Part of the Soul , and not the other ? Certainly , if the Soul is the Image of God , it is his Image wholly , and not partially , or in parts . But your Author has other as strange and odd opinions as these , some whereof I have mentioned in my former Letters , viz. the Souls being a Light , her Figure , her Residence , and many the like : Amongst the rest , there is one thing which your Author frequently makes mention Ch. Of the Magnetick cure of wounds . of ; I know not what to call it , whether a thing , or a being , or no-thing ; for it is neither of them ; not a substance , nor an accident ; neither a body , nor a spirit ; and this Monster ( sor I think this is its proper name , since none other will fit it ) is the Lacquey of the Soul , to run upon all errands ; for the Soul sitting in her Princely Throne or Residence , which is the orifice of the stomack , cannot be every where her self ; neither is it fit she should , as being a disgrace to her , to perform all offices her self for want of servants , therefore she sends out this most faithful and trusty officer , ( your Author calls him Ideal Entity ) who being prepared for his journey , readily performs all her commands , as being not tied up to no commands of places , times or dimensions , especially in Women with Child he operates most powerfully ; for sometime he printed a Cherry on a Child , by a strong Idea of the Mother ; but this Ideal Entity or servant of the Soul , hath troubled my brain more , then his Mistress the Soul her self ; for I could not , nor cannot as yet conceive , how he might be able to be the Jack of all offices , and do Journies and travel from one part of the body to another , being no body nor substance himself , nor tyed to any place , time , and dimension , and therefore I will leave him . Your Author also speaks much of the Inward and Outward Man ; but since that belongs to Divinity , I will declare nothing of it ; onely this I say , that , in my opinion , the Inward and Outward man do not make a double . Creature , neither properly , nor improperly ; properly , as to make two different men ; improperly , as we use to call that man double , whose heart doth not agree with his words . But by the Outward man I understand the sinful actions of flesh and blood , and by the Inward man the reformed actions of the Spirit , according to the Word of God ; and therefore the Outward and Inward man make but one Man . Concerning the Natural Soul , your Author a a Of the seat of the Soul . speaks of her more to her disgrace then to her honor ; for he scorns to call her a substance , neither doth he call her the Rational Soul , but he calls her the Sensitive Soul , and makes the Divine Soul to be the Rational Natural Soul , and the cause of all natural actions ; for he being a Divine Philosopher , mixes Divine and Natural things together : But of the Frail , Mortal , Sensitive Soul , as he names her , which is onely the sensitive Life , his opinions are , that she is neither a substance , nor an accident , but a Neutral Creature , and a Vital Light , which hath not its like in the whole World , but the light of a Candle ; for it is extinguished , and goes out like the flame of a Candle ; it is locally present , and entertained in a place , and yet not comprehended in a place . Nevertheless , although this sensitive soul is no substance , yet it has the honor to be the Inn or Lodging-place of the Immortal Soul or Mind ; and these two souls being both lights , do pierce each other ; but the Mortal soul blunts the Immortal soul with its cogitation of the corruption of Adam . These opinions , Madam , I confess really , I do not know what to make of them ; for I cannot imagine , how this Mortal soul , being no substance , can contain the Immortal soul , which is a substance ; nor how they can pierce each other , and the Mortal soul being substanceless , get the better over an Immortal substance , and vitiate , corrupt , and infect it ; neither can I conceive , how that , which in a manner is nothing already , can be made less and annihilated . Wherefore , my opinion is , that the Natural Soul , Life , and Body , are all substantial parts of Infinite Nature , not subsisting by themselves each apart , but inseparably united and co-mixed both in their actions and substances ; for not any thing can and doth subsist of it self in Nature , but God alone ; and things supernatural may , for ought I know : T is true , there are several Degrees , several particular Natures , several Actions or Motions , and several Parts in Nature , but none subsists single , and by it self , without reference to the whole , and to one another . Your Author says , the Vital Spirit sits in the Throne of the Outward man as Vice Roy of the Soul , and acts by Commission of the Soul ; but it is impossible , that one single part should be King of the whole Creature , since Rational and Sensitive Matter is divided into so many parts , which have equal power and force of action in their turns and severall imployments ; for though Nature is a Monarchess over all her Creatures , yet in every particular Creature is a Republick , and not a Monarchy ; for no part of any Creature has a sole supreme Power over the rest . Moreover , your Author a a Ch. Of the Image of the Mind . says , That an Angel is not a Light himself , nor has an Internal Light , natural and proper to himself , but is the Glass of an Vncreated Light : Which , to my apprehension , seems to affirm , That Angels are the Looking-glasses of God ; a pretty Poetical Fancy , but not grounded on the Scripture : for the Scripture doth not express any such thing of them , but onely that they are Ministring Spirits sent forth to minister for them who shall be heirs of Salvation : Heb. 11. 14. Which , I think , is enough for us to know here , and leave the rest until we come to enjoy their company in Heaven . But it is not to be admired , that those , which pretend to know the Nature and Secrets of God , should not have likewise knowledg of Supernatural Creatures ; In which conceit I leave them , and rest ,

REason and Intellect are two different things to your Author a a Ch. The hunting or searching out of Sciences . It. Of the Image of the Mind . ; for Intellect , says he , doth properly belong to the Immortal Soul , as being a Formal Light , and the very substance of the Soul it self , wherein the Image of God onely consists ; But Reason is an uncertain , frail faculty of the Mortal Soul , and doth in no ways belong , nor has any communion with the Intellect of the Mind . Which seems to me , as if your Author did make some difference between the Divine , and the Natural Soul in Man , although he doth not plainly declare it in the same Terms ; for that which I name the Divine Soul , is to him the Immortal Mind , Intellect , or Understanding , and the Seat of the Image of God ; but the Natural Soul he calls the Frail , Mortal , and Rational Soul ; and as Understanding is the Essence of the Immortal , so Reason is to him the Essence of the Mortal Soul ; which Reason he attributes not only to Man , but also to Brutes : For Reason and Discourse , says he , do not obscurely flourish and grow in brute Beasts , for an aged Fox is more crafty then a younger one by rational discourse ; and again , That the Rational Part of the Soul doth belong to brutes , is without doubt : Wherein he rightly dissents from those , which onely do attribute a sensitive Soul to brutes ; and Reason to none but Man , whom therefore they call a Rational Creature , and by this Rational Faculty do distinguish him from the rest of Animals . And thus I perceive the difference betwixt your Authors opinion , and theirs , is , That other Philosophers commonly do make the Rational soul , to be partly that which I call the supernatural and divine Soul , as onely belonging to man , and bearing the Image of God , not acknowledging any other Natural , but a Sensitive soul in the rest of Animals , and a Vegetative soul in Vegetables ; and these three souls , or faculties , operations , or degrees , ( call them what you will , for we shall not fall out about names , ) concurr and joyn together in Man ; but the rest of all Creatures , are void and destitute ofLife , as well as of Soul , and therefore called Unanimate ; and thus they make the natural rational soul , and the divine soul in man to be all one thing , without any distinguishment ; but your Author makes a difference between the Mortal and Immortal soul in Man ; the Immortal he calls the Intellect or Understanding , and the Mortal soul he calls Reason : but to my judgment he also attributes to the immortal soul , actions which are both natural , and supernatural , adscribing that to the divine soul , which onely belongs to the natural , and taking that from the natural , which properly belongs to her . Besides , he slights and despises the Rational soul so , as if she were almost of no value with Man , making her no substance , but a mental intricate and obscure Being , and so far from Truth , as if there were no affinity betwixt Truth and Reason , but that they disagree in their very roots , and that the most refined Reason may be deceitful . But your Author , by his leave , confounds Reason , and Reasoning , which are two several and distinct things ; for reasoning and arguing differs as much from Reason , as doubtfulness from certainty of knowledg , or a wavering mind from a constant mind ; for Reasoning is the discoursive , and Reason the understanding part in Man , and therefore I can find no great difference between Understanding and Reason : Neither can I be perswaded , that Reason should not remain with Man after this life , and enter with him into Heaven , although your Author speaks much against it ; for if Man shall be the same then , which he is now , in body , why not in soul also ? 'T is true , the Scripture says , he shall have a more glorious body , but it doth not say , that some parts of the body shall be cast away , or remain behind ; and if not of the body , why of the soul ? Why shall Reason , which is the chief part of the natural Soul , be wanting ? Your Author is much for Intellect or Understanding ; but I cannot imagine how Understanding can be without Reason . Certainly , when he saw the Immortal Soul in a Vision , to be a formal Light , how could he discern what he saw , without Reason ? How could he distinguish between Light and Darkness , without Reason ? How could he know the Image of the Mind to be the Image of God , without the distinguishment of Reason ? You will say , Truth informed him , and not Reason . I answer , Reason shews the Truth . You may reply , Truth requires no distinguishment or judgment . I grant , that perfect Truth requires not reasoning or arguing , as whether it be so , or not ; but yet it requires reason , as to confirm it to be so , or not so : for Reason is the confirmation of Truth , and Reasoning is but the Inquisition into Truth : Wherefore , when our Souls shall be in the fulness of blessedness , certainly , they shall not be so dull and stupid , but observe distinctions between God , Angels , and sanctified Souls ; as also , that our glory is above our merit , and that there is great difference between the Damned , and the Blessed , and that God is an Eternal and Infinite Being , and onely to be adored , admired , and loved , and that we enjoy as much as can be enjoyed : All which the Soul cannot know without the distinguishment of Reason ; otherwise we might say , the Souls in Heaven , love , joy , admire and adore , but know not what , why , or wherefore ; For , shall the blessed Souls present continual Praises without reason ? Have they not reason to praise God for their happiness , and shall they not remember the Mercies of God , and the Merits of his Son ? For without remembrance of them , they cannot give a true acknowledgment , although your Author says there is no use of Memory or remembrance in Heaven : but surely , I believe there is ; for if there were not memory in Heaven , the Penitent Thief upon the Cross his Prayers had been in vain ; for he desired our Saviour to remember him when he did come into his Kingdom : Wherefore if there be Understanding in Heaven , there is also Reason ; and if there be Reason , there is Memory also : for all Souls in Heaven , as well as on Earth , have reason to adore , love , and praise God . But , Madam , my study is in natural Philosophy , not in Theology ; and therefore I 'le refer you to Divines , and leave your Author to his own fancy , who by his singular Visions tells us more news of our Souls , then our Saviour did after his Death and Resurrection : Resting in the mean time ,

COncerning those parts and chapters of your Authors Works , which treat of Physick ; before I begin to examine them , I beg leave of you in this present , to make some reflections first upon his Opinions concerning the Nature of Health and Diseases : As for Health , he is pleased to say , a a Ch. Call'd the Authors answers . That it consists not in a just Temperature of the body , but in a sound and intire Life ; for otherwise , a Temperature of body is as yet in a dead Carcass newly kill'd , where notwithstanding there is now death , but not life , not health : Also he says , b b Ch. Of the subject of inhering of diseases . That no disease is in a dead Carcass . To which I answer , That , in my opinion , Life is in a dead Carcass , as well as in a living Animal , although not such a Life as that Creature had before it became a Carcass , and the Temperature of that Creature is altered with the alteration of its particular life ; for the temperature of that particular life , which was before in the Animal , doth not remain in the Carcass , in such a manner as it was when it had the life of such or such an Animal ; nevertheless , a dead Carcass hath life , and such a temperature of life , as is proper , and belonging to its own figure : for there are as many different lives , as there be different creatures , and each creature has its particular life and soul , as partaking of sensitive and rational Matter . And if a dead Carcass hath life , and such a temperature of motions as belong to its own life , then there is no question , but these motions may move sometimes irregularly in a dead Carcass as well , as in any other Creature ; and since health and diseases are nothing else but the regularity or irregularity of sensitive corporeal Motions , a dead Carcass having Irregular motions , may be said as well to have diseases , as a living body , as they name it , although it is no proper or usual term for other Creatures , but onely for Animals . However , if there were no such thing as a disease ( or term it what you will , I will call it Irregularity of sensitive motions ) in a dead Carcass , How comes it that the infection of a disease proceeds often from dead Carcasses into living Animals ? For , certainly , it is not meerly the odour or stink of a dead body , for then all stinking Carcasses would produce an Infection ; wherefore this Infection must necessarily be inherent in the Carcass , and proceed from the Irregularity of its motions . Next I 'le ask you , Whether a Consumption be a disease , or not ? If it be , then a dead Carcass might be said to have a disease , as well as a living body ; and the AEgyptians knew a soveraign remedy against this disease , which would keep a dead Carcass intire and undissolved many ages ; but as I said above , a dead Carcass is not that which it was being a living Animal , wherefore their effects cannot be the same , having not the same causes . Next , your Author is pleased to call , with Hippocrates , Nature the onely Physicianess of Diseases . I affirm it ; and say moreover , that as she is the onely Physicianess , so she is also the onely Destroyeress and Murtheress of all particular Creatures , and their particular lives ; for she dissolves and transforms as well as she frames and creates ; and acts according to her pleasure , either for the increase or decrease , augmentation or destruction , sickness or health , life or death of Particular Creatures . But concerning Diseases , your Authors opinion is , That a Disease is as Natural as Health . I answer ; 't is true , Diseases are natural ; but if we could find out the art of healing , as well as the art of killing and destroying ; and the art of uniting and composing , as well as the art of separating and dividing , it would be very beneficial to man ; but this may easier be wished for , then obtained ; for Nature being a corporeal substance , has infinite parts , as well as an infinite body ; and Art , which is onely the playing action of Nature , and a particular Creature , can easier divide and separate parts , then unite and make parts ; for Art cannot match , unite , and joyn parts so as Nature doth ; for Nature is not onely dividable and composeable , being a corporeal substance , but she is also full of curiosity and variety , being partly self-moving : and there is great difference between forced actions , and natural actions ; for the one sort is regular , the other irregular . But you may say , Irregularities are as natural as Regularities . I grant it ; but Nature leaves the irregular part most commonly to her daughter or creature Art , that is , she makes irregularities for varieties sake , but she her self orders the regular part , that is , she is more careful of her regular actions ; and thus Nature taking delight in variety suffers irregularities ; for otherwise , if there were onely regularities , there could not be so much variety . Again your Author says , That a disease doth not consist but Ch. The subject of inhering of diseases is in the point of life . in living bodies . I answer , there is not any body that has not life ; for if life is general , then all figures or parts have life ; but though all bodies have life , yet all bodies have not diseases ; for diseases are but accidental to It. Ch. Of the knowledg of diseases . bodies , and are nothing else but irregular motions in particular Creatures , which may be not onely in Animals , but generally in all Creatures ; for there may be Irregularities in all sorts of Creatures , which may cause untimely dissolutions ; but yet all dissolutions are not made by irregular motions , for many creatures dissolve regularly , but onely those which are untimely . In the same place your Author mentions , That a Disease consists immediately in Life it self , but not in the dregs and filthinesses , which are erroneous forreigners and strangers to the life . I grant , that a Disease is made by the motions of Life , but not such a life as your Author describes , which doth go out like the snuff of a Candle , or as one of Lucian's Poetical Lights ; but by the life of Nature , which cannot go out without the destruction of Infinite Nature : and as the Motions of Nature's life make diseases or irregularities , so they make that which man names dregs and filths ; which dregs , filths , sickness , and death , are nothing but changes of corporeal motions , different from those motions or actions that are proper to the health , perfection and consistence of such or such a figure or creature . But , to conclude , there is no such thing as corruption , sickness , or death , properly in Nature , for they are made by natural actions , and are onely varieties in Nature , but not obstructions or destructions of Nature , or annihilations of particular Creatures ; and so is that we name Superfluities , which bear onely a relation to a particular Creature , which hath more Motion and Matter then is proper for the nature of its figure . And thus much of this subject for the present , from ,

XXVII . MADAM ,

In my last , I remember , I told you of your Authors opinion concerning the seat of Diseases , viz. that Diseases are properly in living bodies , and consist in the life it self ; but when I consider his definition of Life , and of a Disease , I cannot conceive how they should consist together ; for he describes a a Ch. Of the knowledg of diseases . a Disease to be a real , material and substantial being , truly subsisting in a body ; but life to be a meer nothing , and yet the immediate mansion of a disease , the inward subject , yea , and workman of the same ; and that with the life all diseases depart into nothing . Surely , Madam , it exceedeth my understanding ; for , first , I cannot conceive how life , which is a meer Nothing , can be a lodging to something ? Next , how Nothing can depart and die ? and thirdly how Something can become Nothing ? I think your Author might call a dead Carcass as well No-thing , as Life ; and since he names Diseases the Thieves of Life , they must needs be but poor Thieves , because they steal No-thing . But your Author compares Life to Light , and calls it an Extinguishable Light , like the light of a Candle ; which if so , then the old saying is verified , That life goes out like the snuff of a Candle . But I wonder , Madam , that grave and wise men will seriously make use of a fimilifing old Proverb , or of a Poetical Fancy , in matter of natural Philosophy ; for I have observed , that Homer , Lucian , Ovid , Virgil , Horace , &c. have been very ferviceable to great Philosophers , who have taken the ground of their Fictions , and transferred them into Natural Philosophy , as Immaterial substances , Non-beings , and many the like ; but they can neither do any good nor hurt to Nature , but onely spoil Philosophical Knowledg ; and as Nature is ignorant of Immaterials and Non-beings , so Art is ignorant of Nature ; for Mathematical Rules , Measures , and Demonstrations , cannot rule , measure nor demonstrate Nature , no more , then Chymical Divisions , Dissolutions and Extractions ( or rather distractions , nay , I may say destructions ) can divide , dissolve , extract , compose , and unite , as Nature doth ; Wherefore their Instruments , Figures , Furnaces , Limbecks , and Engines , cannot instruct them of the truth of Natures Principles ; but the best and readiest way to find out Nature , or rather some truth of Nature , is sense and reason , which are Parts of Natures active substance , and therefore the truest informers of Nature ; but the Ignorance of Nature has caused Ignorance amongst Philosophers , and the Ignorance of Philosophers hath caused numerous Opinions , and numerous Opinions have caused various Discourses and Disputes ; which Discourses and Disputes , are not Sense and Reason , but proceed from Irregular Motions ; and Truth is not found in Irregularities . But to return to Life : it seems your Author hath taken his opinion from Lucian's Kingdom of Lights , the Lights being the Inhabitants thereof ; and when any was adjudged to die , his Light was put out , which was his punishment : And thus this Heathenish Fiction is become a Christian Verity ; when as yet your Author rayls much at those , that insist upon the Opinions and Doctrine of Pagan Philosophers . Wherefore I will leave this Poetical Fancy of Life , and turn to Death , and see what opinion your Author hath of that . First , concerning the cause or original of Death ; Neither God , says he a a Ch. Called the Position . , nor the Evil Spirit , is the Creator of Death , but Man onely , who made death for himself ; Neither did Nature make death , but Man made death natural . Which if it be so , then Death being , to my opinion , a natural Creature , as well as Life , Sickness , and Health ; Man , certainly , had great Power , as to be the Creator of a natural Creature . But , I would fain know the reason , why your Author is so unwilling to make God the Author of Death , and Sickness , as well as of Damnation ? Doth it imply any Impiety or Irreligiousness ? Doth not God punish , as well as reward ? and is not death a punishment for our sin ? You may say , Death came from sin , but sin did not come from God . Then some might ask from whence came sin ? You will say , From the Transgression of the Command of God , as the eating of the Forbidden Fruit. But from whence came this Transgression ? It might be answer'd , From the Perswasion of the Serpent . From whence came this Perswasion ? From his ill and malitious nature to oppose God , and ruine the race of Mankind . From whence came this ill Nature ? From his Fall . Whence came his Fall ? From his Pride and Ambition to be equal with God . From whence came this Pride ? From his Free-will . From whence came his Free-will ? From God . Thus , Madam , if we should be too inquisitive into the actions of God , we should commit Blasphemy , and make God Cruel , as to be the Cause of Sin , and consequently of Damnation . But although God is not the Author of Sin , yet we may not stick to say , that he is the Author of the Punishment of Sin , as an Act of his Divine Justice ; which Punishment , is Sickness , and Death ; nay , I see no reason , why not of Damnation too , as it is a due punishment for the sins of the wicked ; for though Man effectively works his own punishment , yet Gods Justice inflicts it : Like as a just Judg may be call'd the cause of a Thief being hang'd . But these questions are too curious ; and some men will be as presumptuous as the Devil , to enquire into Gods secret actions , although they be sure that they cannot be known by any Creature . Wherefore let us banish such vain thoughts , and onely admire , adore , love , and praise God , and implore his Mercy , to give us grace to shun the punishments for our sins by the righteousness of our actions , and not endeavour to know his secret designs . Next , I dissent from your Author a a Ch. Of the knowledg of diseases . , That Death and all dead things do want roots whereby they may produce : For death , and dead things , in my opinion , are the most active producers , at least they produce more numerously and variously then those we name living things ; for example , a dead Horse will produce more several Animals , besides other Creatures , then a living Horse can do ; but what Archeus and Ideas a dead Carcass hath , I can tell no more , then what Blas or Gas it hath ; onely this I say , that it has animate Matter , which is the onely Archeus or Master-workman , that produces all things , creates all things , dissolves all things , and transforms all things in Nature ; but not out of Nothing , or into Nothing , as to create new Creatures which were not before in Nature , or to annihilate Creatures , and to reduce them to nothing ; but it creates and transforms out of , and in the same Matter which has been from all Eternity . Lastly , your Author is pleased to say , That he doth not behold a disease as an abstracted Quality ; and that Apoplexy , Leprosie , Dropsie , and Madness , as they are Qualities in the abstract , are not diseases . I am of his mind , that a disease is a real and corporeal being , and do not understand what he and others mean by abstraoted qualities ; for Nature knows of no abstraction of qualities from substances , and I doubt Man can do no more then Nature doth : Besides , those abstractions are needless , and to no purpose ; for no Immaterial quality will do any hurt , if it be no substance ; wherefore Apoplexy , Leprosie , Dropsie , and Madness , are Corporeal beings , as well as the rest of Diseases , and not abstracted Qualities ; and I am sure , Persons that are affected with those diseases will tell the same . Wherefore leaving needless abstractions to fancies abstracted from right sense and reason , I rest ,

I Am very much troubled to see your Authors Works fill'd with so many spiteful reproaches and bitter taunts against the Schools of Physicians , condemning both their Theory and Practice ; nay , that not onely the Modern Schools of Physicians , but also the two ancient and famous Physicians , Galen , and Paracelsus , must sufficiently suffer by him ; especially Galen ; for there is hardly a Chapter in all his Works , which has not some accusations of blind errors , sloth , and sluggishness , Ignorance , Covetousness , Cruelty , and the like : Which I am very sorry for ; not onely for the sake of your Author himself , who herein doth betray both his rashness , and weakness , in not bridling his passions , and his too great presumption , reliance and confidence in his own abilities , and extraordinary Gifts ; but also for the sake of the Fame and Repute of our Modren Physicians ; for without making now any difference betwixt the Galenists and Paracelsians , and examining which are the best , ( for I think them both excellent in their kinds , especially when joyned together ) I will onely say this in general ; that the Art of Physick has never flourish'd better then now , neither has any age had more skilful , learned , and experienced Physicians , then this present ; because they have not onely the knowledg and practise of those in ages Past , but also their own experience joyned with it , which cannot but add perfection to their Art ; and I , for my part , am so much for the old way of Practice , that ifI should be sick , I would desire rather such Physicians which follow the same way , then those , that by their new Inventions , perchance , cure one , and kill a hundred . But your Author * * In his Promises , Column . 3. will have a Physician to be like a Handycrafts man , who being call'd to a work , promises that work , and stands to his promise ; and therefore , It is a shame , says he , in a Physician , being call'd to a sick-man in the beginning of the disease , and when his strength is yet remaining , to suffer the same man to die . This , in my opinion , is a very unreasonable comparison , to liken a Handicrafts man to a Physician , and the art of Curing to the art of Building , or any the like , without regard of so many great differences that are between them , which I am loth to rehearse , for brevities sake , and are apparant enough to every one that will consider them : but this I may say , that it is not always for want of skill and industry in a Physician , that the cure is not effected , but it lies either in the Incureableness of the disease , or any other external accidents that do hinder the success : Not but that the best Physicians may err in a disease , or mistake the Patients inward distemper by his outward temper , or the interior temper by his outward distemper , or any other ways ; for they may easily err through the variaction of the disease , which may vary so suddenly and oft , as it is impossible to apply so fast , and so many Medicines , as the alteration requires , without certain death ; for the body is not'able , oftentimes , to dispose and digest several Medicines so fast , as the disease may vary , and therefore what was good in this temper , may , perhaps , be bad in the variation ; insomuch , that one medicine may in a minute prove a Cordial , and Poyson . Nay , it may be that some Physicians do err through their own ignorance and mistake , must we therefore condemn all the skill , and accuse all the Schools of Negligence , Cruelty , and Ignorance ? God forbid : for it would be a great Injustice . Let us rather praise them for the good they do , and nor rashly condemn them for the evil they could not help : For we may as well condemn those holy and industrious Divines , that cannot reform wicked and perverse Sinners , as Physicians , because they cannot restore every Patient to his former health , the Profession of a Physician being very difficult ; for they can have but outward signs of inward distempers . Besides , all men are not diffected after they are dead , to inform Physicians of the true cause of their death ; nay , if they were , perchance they would not give always a true information to the Physician , as is evident by many examples ; but oftentimes the blame is laid upon the Physician , when as the fault is either in Nature , or any other cause , which Art could not mend . And if your Author had had such an extraordinary Gift from God as to know more then all the rest of Physicians , why did he not accordingly , and as the Scripture speaks of Faith , shew his skill by his Works and Cures ? certainly , could he have restored those that were born blind , lame , deaf and dumb , or cured the spotted Plague , or Apoplexy after the third fit , or the Consumption of Vital parts , or a Fever in the Arteries , or dissolved a Stone too big to go through the passage , and many the like ; he would not onely have been cried up for a rare Physician , but for a miracle of the World , and worshipped as a Saint : But if he could not effect more then the Schools can do , why doth he inveigh so bitterly against them ? Wherefore I cannot commend him in so doing ; but as I respect the Art of Physick , as a singular Gift from God to Mankind , so I respect and esteem also learned and skilful Physicians , for their various Knowledg , industrious Studies , careful Practice , and great Experiences , and think every one is bound to do the like , they being the onely supporters and restorers of humane life and health : For though I must confess , with your Author , that God is the onely giver of Good , yet God is not pleased to work Miracles ordinarily , but has ordained means for the restoring of health , which the Art of Physick doth apply ; and therefore those Persons that are sick , do wisely to send for a Physician ; for Art , although it is but a particular Creature , and the handmaid of Nature , yet she doth Nature oftentimes very good service ; and so do Physicians often prolong their Patients lives . The like do Chirurgeons ; for if those Persons that have been wounded , had been left to be cured onely by the Magnetick Medicine , I believe , numbers that are alive would have been dead , and numbers would die that are alive ; insomuch , as none would escape , but by miracle , epecially if dangerously hurt . Concerning the Coveteousness of Physicians , although sickness is chargeable , yet I think it is not Charitable to say or to think , that Physitians regard more their Profit , then their Patients health ; for we might as well condemn Divines for taking their Tithes and Stipends , as Physicians for taking their Fees : but the holy Writ tells us , that a Labourer is Worthy of his hire or reward ; and , for my part , I think those commit a great sin , which repine at giving Rowards in any kind ; for those that deserve well by their endeavours , ought to have their rewards ; and such Meritorious Persons , I wish with all my Soul , may prosper and thrive . Nevertheless , as for those persons , which for want of means are not able to reward their Physicians , I think Physicians will not deal so unconscionably , as to neglect their health and lives for want of their Fees , but expect the reward from God , and be recompenced the better by those that have Wealth enough to spare . And this good opinion I have of them . So leaving them , I rest ,

I Am of your Authors mind , That heat is not the cause of digestion ; but I dissent from him , when he says , That it is the Ferment of the stomach that doth cause it : For , in my opinion , Digestion is onely made by regular digestive motions , and ill digestion is caused by irregular motions , and when those motions are weak , then there is no digestion at all , but what was received , remains unaltered ; but when they are strong and quick , then they make a speedy digestion . You may ask me , what are digestive motions ? I answer , They are transchanging , or transforming motions : but since there be many sorts of transchanging motions , digestive motions are those , which transchange food into the nourishment of the body , and dispose properly , fitly and usefully of all the Parts of the food , as well of those which are converted into nourishment , as of those which are cast forth . For give me leave to tell you , Madam , that some parts of natural Matter , do force or cause other parts of Matter to move and work according to their will , without any change or alteration of their parts ; as for example , Fire and Metal ; for Fire will cause Metal to flow , but it doth not readily alter it from its nature of being Metal ; neither doth Fire alter its nature from being Fire . And again , some parts of Matter will cause other parts to work and act to their own will , by forcing these over-powred parts to alter their own natural motions into the motions of the victorious Party , and so transforming them wholly into their own Figure ; as for example , Fire will cause Wood to move so as to take its figure , to wit , the figure of Fire , that is , to change its own figurative motions into the motions of Fire : and this latter kind of moving or working is found in digestion ; for the regular digestive motions do turn all food received from its own nature or figure , into the nourishment , figure , or nature of the body , as into flesh , blood , bones , and the like . But when several parts of Matter meet or joyn with equal force and power , then their several natural motions are either quite altered , or partly mixt : As for example ; some received things not agreeing with the natural constitution of the body , the corporeal motions of the received , and those of the receiver , do dispute or oppose each other : for the motions of the received , not willing to change their nature conformable to the desire of the digestive motions , do resist , and then a War begins , whereby the body suffers most ; for it causes either a sickness in the stomack , or a pain in the head , or in the heart , or in the bowels , or the like : Nay , if the received food gets an absolute victory , it dissolves and alters oftentimes the whole body , it self remaining intire and unaltered , as is evident in those that die of surfeits . But most commonly these strifes and quarrels , if violent , do alter and dissolve each others forms or natures . And many times it is not the fault of the Received , but of the Receiver ; as for example , when the digestive and transforming motions are either irregular , or weak ; for they being too weak , or too few , the meat or food received is digested onely by halves ; and being irregular , it causes that which we call corruption . But it may be observed , that the Received food is either agreeable , or disagreeable , to the Receiver ; if agreeable , then there is a united consent of Parts , to act regularly and perfectly in digestion ; if disagreeable , then the Received acts to the Ruine , that is , to the alteration or dissolution of the Nature of the Receiver ; but if it be neutral , that is , neither perfectly agreeable , nor perfectly disagreeable , but between both , then the receiver , or rather the digestive Motions of the receiver , use a double strength to alter and transform the received . But you may ask me , Madam , what the reason is , that many things received , after they are dissolved into small parts , those parts will keep their former colour and savour ? I answer ; The cause is , that either the retentive Motions in the Parts of the received , are too strong for the digestive and alterative Motions of the receiver , or perchance , this colour and savour is so proper to them , as not to be transchanged : but you must observe , that those digestive , alterative and transchanging motions , do not act or move all after one and the same manner ; for some do dissolve the natural figure of the received , some disperse its dissolved parts into the parts of the body , some place the dispersed parts fitly and properly for the use , benefit , and consistence of the body ; for there is so much variety in this one act of digestion , as no man is able to conceive ; and if there be such variety in one Particular natural action , what variety will there not be in all Nature ? Wherefore , it is not , as I mentioned in the beginning , either Ferment , or Heat , or any other thing , that causes digestion ; for if all the constitution and nature of our body was grounded or did depend upon Ferment , then Brewers and Bakers , and those that deal with Ferments , would be the best Physicians . But I would fain know the cause which makes Ferment ? You may say , saltness , and sowreness . But then I ask , From whence comes saltness and sowreness ? You may say , From the Ferment . But then I shall be as wise as before . The best way , perhaps , may be to say , with your Author , that Ferment is a Primitive Cause , and a beginning or Principle of other things , and it self proceeds from nothing . But then it is beyond my imagination , how that can be a Principle of material things , which it self is nothing ; that is , neither a substance , nor an accident . Good Lord ! what a stir do men make about nothing ! I am amazed to see their strange Fancies and Conceptions vented for the Truest Reasons : Wherefore I will return to my simple opinion ; and as I cannot conceive any thing that is beyond Matter , or a Body ; so I believe , according to my reason , that there is not any part in Nature , be it never so subtil or small , but is a self-moving substance , or endued with self-motion ; and according to the regularity and irregularity of these motions , all natural effects are produced , either perfect , or imperfect ; timely births , or untimely and monstrous births ; death , health , and diseases , good and ill dispositions , natural and extravagant Appetites and Passions , ( I say natural , that is , according to the nature of their figures ; ) Sympathy and Antipathy , Peace and War , Rational and Phantastical opinions . Nevertheless , all these motions , whether regular or irregular , are natural ; for regularity and irregularity hath but a respect to particulars , and to our conceptions , because those motions which move not after the ordinary , common or usual way or manner , we call Irregular . But the curiosity and variety in Nature is unconceiveable by any particular Creature ; and so leaving it , I rest ,

YOur Author says a a Ch. Of a Six-fold digestion . , it is an ancient Truth , That whatsoever things , meats being digested and cast out by vomit , are of a sowre taste and smell , yea , although they were seasoned with much sugar . But I do not assent to this opinion ; for I think that some Vomits have no more taste then pure Water hath . Neither am I of his mind , That Digestion is hastened by sharpness or tartness : For do but try it by one simple experiment ; take any kind of flesh-meat , boyl or stew it with Vinegar , or sowre wine , or with much salt ; and you will find , that it doth require a longer time , or rather more motions to dissolve , then if you boyl it in fair water , without such ingredients as are sowre , sharp , or salt ; also if you do but observe , you will find the dregs more sandy , stony and hard , being drest with much salt , and sharp wine , or vinegar , then when they are not mixt with such contracting and fixing Ingredients ? Wherefore , if the Ferment of the stomack hath such a restringent and contracting quality , certainly digestions will be but slow and unprofitable ; but Nature requires expulsion as much as attraction , and dilation as much as contraction , and digestion is a kind of dilation . Wherefore , in my judgment , contracting tartness and sharpness doth rather hinder digestion then further it . Next I perceive , your Author inclines to the opinion , That Choler is not made by meat * * See The passive deceiving of the Schools , the humorists , C. I. : But I would ask him , whether any humor be made ofmeat , or whether blood ; flesh , &c. are made and nourished by meat ? If they be not , then my answer is , That we eat to no purpose ; but if they be , then Choler is made so too . But if he says , That sorne are made , and some not ; then I would ask , what that humor is made of , that is not made by meat or food received into the body ? But we find that humors , blood , flesh , &c. will be sometimes more , sometimes less , according either to feeding , or to digestion , which digestion is a contribution of food to every several part of the body for its nourishment ; and when there is a decay ofthose parts , then it is caused either by fasting , or by irregular digestion , or by extraordinary evacuation , or by distempered matter , &c. all which , causes sickness , paleness , leanness ; weakness , and the like . Again : your Author is against the opinion of the Schools , That the Gall is a receptacle of superfluous humors and dregs : for he says , it has rather the constitution of a necessary and vital bowel , and is the balsom of the liver and blood . Truly , it may be so , for any thing I know , or it may be not ; for your Author could but guess , not assuredly know , unless he had been in a man as big as the Whale in whose belly Jonas was three days , and had observed the interior parts and motions of every part for three years time , and yet he might perchance have been as ignorant at the coming forth , as if he never had been there ; for Natures actions are not onely curious , but very various ; and not onely various , but very obscure ; in so much , as the most ingenious Artists cannot trace her ways , or imitate her actions ; for Art being but a Creature , can do or know no more then a Creature ; and although she is an ingenious Creature , which can and hath found out some things profitable and useful for the life of others , yet she is but a handmaid to Nature , and not her Mistress ; which your Author , in my opinion , too rashly affirms , when he says , That the Art of Chymistry is not onely the Chambermaid and emulating Ape , but now and Ch. Heat doth not digest efficiently . then the Mistress of Nature : For Art is an effect of Nature , and to prefer the effect before the cause , is absurd . But concerning Chymistry , I have spoken in another place ; I 'le return to my former Discourse : and I wonder much why your Author is so opposite to the Schools , concerning the doctrine of the Gall's being a receptacle for superfluities and dregs ; for I think there is not any Creature that has not places or receptacles for superfluous matter , such as we call dregs ; for even the purest and hardest Mineral , as Gold , has its dross , although in a less proportion then some other Creatures ; nay , I am perswaded , that even Light , which your Author doth so much worship , may have some superfluous matter , which may be named dregs ; and since Nature has made parts in all Creatures to receive and discharge superfluous matter , ( which receiving and discharging is nothing else but a joyning and dividing of parts to and from parts , ) why may not the Gall be as well for that use as any other part ? But I pray mistake me not , when I say superfluous matter or dregs ; for I understand by it , that which is not useful to the nourishment or confistence of such or such a Creature ; but to speak properly , there is neither superfluity of matter nor dregs in Nature . Moreover , your Author mentions a six-fold digestion , and makes every digestion to be performed by inbreathing or inspiration ; For in the first digestion , he says , The spleen doth inspire a sowre Ferment into the Meat : In the second , The Gall doth inspire a ferment , or fermental blas into the slender entrails : In the third , The Liver doth inspire a bloody ferment into the veins of the Mensentery , &c. I answer , first , I am confident Nature has more ways then to work onely by Inspirations , not onely in General , but in every Particular . Next , I believe there are not onely six , but many more digestions in an animal Creature ; for not onely every sort of food , but every bit that is eaten , may require a several digestion , and every several part of the body works either to expel , or preserve , or for both ; so that there are numerous several Motions in every Creature , and many changes of motions in each particular part ; but Nature is in them all . And so leaving her , I rest ,

YOur Author , in opposition to the Schools , endeavouring to prove that there are no humors in an animal body , except blood , proves many humors in himself . But I can see no reason , why Nature should not make several humors , as well as several Elements , Vegetables , Minerals , Animals , and other Creatures ; and that in several parts of the body , and many several ways ; for to mention but one sort of other Creatures , viz. Vegetables , they are , as we see , not onely produced many several ways , but in many several grounds ; either by sowing , setting , or grafting , either in clayie , limy , sandy , chalky , dry , or wet grounds : And why may not several humors be produced as well of other Creatures and parts , as others are produced of them ? for all parts of Nature are produced one from another , as being all of one and the same Matter , onely the variation of corporeal motions makes all the difference and variety between them , which variety of motions is impossible to be known by any particular Creature ; for Nature can do more then any Creature can conceive . Truly , Madam , I should not be of such a mind , as to oppose the Schools herein so eargerly as your Author doth ; but artificial actions make men to have erroneous opinions of the actions of Nature , judging them all according to the rule and measure of Art , when as Art oft deludes men under the cover of truth , and makes them many times believe falshood for truth ; for Nature is pleased with variety , and so doth make numerous absurdities , doubts , opinions , disputations , objections , and the like . Moreover , your Author is as much against the radical moisture , as he is against the four humors ; saying , that according to this opinion of the Schools , a fat belly , through much grease affording more fuel to the radical moisture , must of necessity live longer . But this , in my opinion , is onely a wilful mistake ; for I am confident , that the Schools do not understand radical moisture to be gross , fat radical oyl , but a thin oylie substance . Neither do they believe radical heat to be a burning , fiery and consuming heat , but such a degree of natural heat , as is comfortable , nourishing , refreshing , and proper for the life of the animal Creature : Wherefore radical heat and moisture doth not onely consist in the Grease of the body ; for a lean body may have as much , and some of them more Radical moisture , then fat bodies . But your Author instead of this radical moisture , makes a nourishable moisture , onely , as I suppose , out of a mind to contradict the Schools ; when as I do not perceive , that the Schools mean by Radical moisture , any other then a nourishable moisture , and therefore this distinction is needless . Lastly , he condemns the Schools , for making an affinity betwixt the bowels and the brain . But he might as will condemn Politicians , for saying there is an affinity betwixt Governors and Subjects , or betwixt command and obedience ; but as the actions of Particulars , even from the meanest in a Common-wealth , may chance to make a Publick disturbance , so likewise in the Common-wealth of the body , one single action in a particular part may cause a disturbance of the whole Body , nay , a total ruine and dissolution of the composed ; which dissolution is called Death ; and yet these causes are neither Light , nor Blas , nor Gas , no more then men are shining Suns , or flaming Torches , or blazing Meteors , or azure Skies . Wherefore leaving your Author to his contradicting humor , I rest ,

I Do verily believe , with the Schools , the Purging of the Brain , against your Author ; a a Ch. Call'd The Erring Watchman , or Wandring Keeper . For I know no reason , why all the parts of a man's body should not stand in need of evacuation and purging , as well as some . 'T is true , if the substance or nourishment received were all useful , and onely enough for the maintenance , subsistance and continuance of the Creature , and no more , then there would be no need of such sort of evacuation ; but I believe the corporeal self-motions in a body , discharge the superfluous matter out of every part of the body , if the motions of the superfluous matter be not too strong , and over-power the motions in the parts of the body ; but some parts do produce more superfluities then others , by reason their property is more to dilate , then to contract , and more to attract , then to retain or fix ; which parts are the brain , stomack , bowels , bladder , gall , and the like : wherefore , as there is nourishment in all parts of the body , so there are also excrements in all parts , for there is no nourishment without excrement . Next your Author says , That the nourishment of the solid parts is made with the transmutation of the whole venal blood into nourishment , without a separation of the pure from the impure . But I pray give me leave to ask , Madam , whether the solid Parts are not Instruments for the nourishment of the Venal blood ? Truly , I cannot conceive , how blood should be nourished , wanting those solid parts , and their particular motions and imployments . Again : his opinion is , That the brain is nourished by a few and slender veins ; neither doth a passage or channel appear whereby a moist excrement may derive , or a vapour enter . And by reason of the want of such a passage , in another place a a Ch. call'd The Spirit of Life . he is pleased to affirm , That nothing can fume up from the stomack into the brain , and therefore Wine doth not make drunk with fuming from the stomach into the head , but the Winie spirit is immediately snatched into the arteries out of the stomack without digestion , and so into the head , and there breeds a confusion . First , I am not of the opinion , that all nourishment comes from the veins , or from one particular part of the body , no more do Excrements ; neither do I believe that every passage in the body is visible to Anatomists , for Natures works are too curious and intricate for any particular Creature to find them out , which is the cause that Anatomists and Chymists are so oft mistaken in natural causes and effects ; for certainly , they sometimes believe great Errors for great Truths . Next , as for Drunkenness , I believe that many , who drink much Wine , are drunk before such time as the Wine spirit can get into the Arteries ; but if there be Pores to the Brain , as it is most probable , the spirit of Wine may more easily ascend and enter those Pores , then the Pores of the Arteries , or the Mouth-veins , and so make a circular journey to the Head . But as for Excrements , whereof I spake in the beginning , as they are made several manners or ways , and in several parts of the body , so they are also discharged several ways from several parts , and several ways from each particular part , indeed so many several ways and manners , as would puzzle the wisest man in the world , nay your Authors Interior keeper of the Brain , to find them out . Wherefore , to conclude , he is the best Physician , that can tell how to discharge superfluity , and to retain useful nourishments ; or to restore by the application of proper Medicines , decaying parts , or to put in order Irregular motions ; and not those that have Irregular opinions of Immaterial causes : To which , I leave them , and rest ,

XXXIII . MADAM ,

I Do not approve of your Authors Doctrine , forbidding Phlebotomy or blood-letting in Fevers , opposite to the received Practice of the Schools ; his reason is , that he believes there can be no corruption in the blood . Corrupted blood , says he , cannot be in the veins , neither doth a state of ill juice consist in the veins ; for In his Treatise of Fevers , c. 4. Gangrenes do teach , that nothing of Putrified matter can long persist without a further contagion of it self . Also he says , That the blood of the veins is no otherwise distinguished by its several colours and signs , then as wine is troubled when the vine flourisheth . To which I answer , first , That I can see no reason why there should not be as well corrupt blood , or an ill state of juice in the veins , as ill humors in the body . Perchance he will say , There is no corruption in the body . But Ulcers do teach the contrary . He may reply , Ulcers are not parts of the body . I answer , T is true ; but yet they are evil Inhabitants in the body , and the like may be in the Veins . But surely some men may have corrupted parts of their bodies , and yet live a great while ; witness Ulcers in the Lungs , and other parts . But your Author may say , When a part of the body is corrupted , it is no longer an animal Part. I grant it : but yet , as I said , that transformed part may remain in the body some time without destruction of the whole body ; and so likewise , when some of the blood , is transchanged from being blood , so as not to be capable to be reduced again , it may nevertheless remain in the veins without destruction of the veins , or of the whole body : Neither do I conceive any reason , why corrupt blood should Gangrene in the veins , and infect the adjoyning parts more then corrupted lungs do . Next , as for the comparison of the various colours and signs of the blood , with Wine being troubled when the Vine is flourishing ; I answer , That it doth not prove any thing ; for we speak of such colours , as are signs of corrupted , and not such as are signs of troubled blood : Besides , it is an unlike comparison ; for though Wine may become thick by much fermentation , yet it doth not turn into water , as blood in some sick and diseased persons will do . But corrupted blood may be , not onely in the veins of sick , but also of healthy persons ; and the story says , that Seneca , when his veins were cut , they would not bleed , although in a hot Bath , by reason that which was in the veins , was rather like a white jelly , then blood , and yet he was healthy , though old ; which proves , that it is not necessary for the blood to be so pure and fluid as your Author will have it . The truth is , the more fluid the blood is , the weaker it is ; like balsam , the more gummy it is , the stronger it is : but veins , which are the mouth , to receive or suck in juices , as also the stomack which digests the meat that after is turned into blood , may be defective either through weakness , superfluity , obstruction , corruption , or evil and hurtful diet , or through the disorders of other particular parts , which may disturb all the parts in general , as skilful Physicians have observed , and therefore apply remedies accordingly ; for if the defect proceeds from weakness , they give strengthening remedies ; if from superfluities , they give evacuating remedies ; if from evil diets , they prescribe such a course of diet as shall be beneficial , and conducing for the restoring of health to the whole body . But your Author , as I perceive , believes the blood to be the chief vital part of the body ; which surely it is not : for if it were , the least disturbance of the blood would endanger the life of the whole body , and the least diminution would cause a total dissolution of that animal Creature which has blood : Not but that blood is as necessary as breath for respiration , and food for nourishment of the body ; but too much blood is as dangerous to the life of the animal body , as too great a piece of food , which cannot be swallowed down , bu● doth stick in the throat , and stop the breath , or so much quantity as cannot be digested ; for too great a fulness or abounding makes a stoppage of the blood , or which is worse , causes the veins to break , and an evil digestion , makes a corruption , or at least such disorder as to indanger the whole animal Figure . But some veins breed more blood , and some less , and some better , and some worse blood , some hotter , and some colder , some grosser , and some purer , some thicker , and some thinner ; and some veins breed rather an evil juice or corrupt matter then pure blood ; the truth is , blood is bred somewhat after the manner of Excrements , for the veins are somewhat like the guts , wherein the excrements are digested . But you will say , A man may live without excrements , but not without blood . I answer : a man can live no more without excrements and excremental humors , then he can without blood : but yet I am not of your Authors mind , that bleeding and purging are destructive ; for superfluities are as dangerous as scarcities , nay more ; like as an house filled with rubbish is in more danger to sink or fall , then that which is empty ; and when a house is on fire , it is wisdom to take out the Moveables , but a folly to let them increase the flame . But your Author says , Blood-letting takes not onely away the bad , but also the good blood , by which it diminishes and impairs much the strength of the body . I will answer by way of question , Whether in War men would not venture the loss of some few friends , to gain the victory , or save the whole body of the Army ? or whether the destroying of the enemies Army be not more advantageous , then the loss of some few friends ? For although some good blood may issue out with the bad , yet the veins have more time , room , and some more power to get friendly juices from the several parts of the body , which will be more obedient , trusty , and true to the life and service of the whole body . But neither Fevers , nor any other distempers , will be more afraid of your Authors words , Stones , Spirits , as also Rings , Beads , Bracelets , and the like toys , fitter for Children to play withal , then for Physicians to use ; then an Army of men will be of their enemies Colours , Ensigns , Feathers , Scarfs , and the like ; knowing it must be Swords , Pistols , Guns , Powder and Bullets , that must do the business to destroy the enemy , and to gain the victory : Wherefore in Diseases it must be Bleeding , Purging , Vomiting , using of Clysters , and the like , if any good shall be done . 'T is true , they must well be ordered , otherwise they will do more hurt then good ; for Diseases are like Enemies , which sometimes take away our Armes for their own uses . But your Author says again , That the Matter of a Fever floats not in the veins , nor sits nigh the heart . I answer : There are several sorts of Fevers ; for all Fevers are not produced after one and the same manner , or from one and the same cause , as is very well known to wise and experienced Physicians ; but although some Fevers are not in the blood , yet that doth not prove , that the blood is never in a Fever ; for sometimes the blood is in a Fever , and not the solid parts ; and sometimes the fluid and moveable humors , and not the blood , or solid parts ; and sometimes the solid parts , and not the blood , nor the liquid and moveable humors ; and sometimes they are all in a Fever ; and sometimes onely the radical parts , and neither the blood , humors , nor solid parts : and this last kind of Fever , which is a hectick Fever , in my opinion , is incureable ; but the others may be cureable , if there be not too many varieties of distempers , or irregular motions . And as for a Fever in the solid parts , Letting of blood , and taking away the humor , may cure it ; for the veins being empty , suck the heat out of the solid parts , which solid parts cannot draw out a distempered heat in the veins , and the opening of the veins gives vent to some of the interior heat to issue forth : Wherefore it is very requisite , that in all sorts of Fevers , except Hectick-Fevers , blood-letting should be used , not onely once , but often ; for 't is better to live with a little blood , and a little strength , which will soon be recovered , then to die with too much , or too hot and distempered blood . Also Purging , but especially Vomiting is very good ; for if the humors be in a Feaver , they may infect the vital parts , as also the blood ; but if they be not in a Fever , yet the solid parts or blood may do the same , and so make the contagion greater ; for the humors are as the moveables in a house , which ought to be cast out if either they or the house should be on fire ; and if a disorder proceeds from the error of a particular part , then care must be taken to rectifie that part for the health of the whole : Wherefore Physicians use in some cases Blood-letting , in some Purging , in some Vomiting , in some Bathing , in some Sweating , in some Cordials , especially after much evacuation , in some they prescribe a good diet , and in some they mix and prescribe partly one and partly the other , and in some cases they are forced to use all these remedies ; for though great evacuations may cause weakness , yet they often save the life ; and there is no Patient , but had rather lose some strength , then life ; for life can gather strength again ; but all strong men are not always long lived , nor all long-lived men very strong ; for many that are but weak , will live to a very old age . Lastly , concerning what your Author says , that there is but one Choler and Phlegme in Nature ; I answer , That is more then he knows : for all that is in Nature , is not nor cannot be known by any Particular Creature ; and he might say , as well , the same of particular Metals , as that there is but one sort of Gold or Silver , when as there is great difference in the weight , purity , colour , and gloss , of several parts of Gold and Silver : Neither is all Gold found in one place ; but some is found in Rocks , some in Sand , some in Mines , some in Stones ; and so Silver , some is found in the bowels of the Earth , some in the veins of Stones , and some in other Metals , as Lead , and Iron , and some in Coals . And the like may be said of Choler and Phlegme ; for they may be several in several places or parts of the body , and be of different colours , tastes , odours , and degrees of heat or cold , thinness or thickness , or the like ; for though there is but one Matter in Nature , yet this onely Matter by its several actions or motions changes into several figures , and so makes several sorts of Creatures , and different particulars in every sort . And thus , Madam , I have delivered unto you my opinion concerning the cure of Fevers by Blood-letting : Which I submit to the correction of your better judgment , and rest ,

MADAM , Your faithful Friend and Servant .
XXXIV . MADAM ,

YOur Author is not onely against Phlebotomy or Blood-letting , but against all Purging Medicines , which he condemns to carry a hidden poyson in them , and to be a cruel and stupid invention . But certainly he shall not have my assent ; for if they be Poyson , they are a very beneficial Poyson ; and Physical Purgations , in my opinion , are very necessary and profitable for the prolonging of life , and taking away of diseases , provided they be proper for those diseases in which they are used ; and so is Phlebotomy , Vomits , and the like : but Medicines are often wrong applyed , and many times the disease is so various , that it is as hard for a Physician to hit right with several Medicines , as for a Gunner or Shooter to kill with Powder and small Shot a Bird flying in the Air ; not that it is not possible to be done , but it is not ordinary , or frequent : neither doth the fault onely lie in the Gun , Powder , or Shot , but in the swiftness of the flight of the Bird , or in the various motion of the air , or in a sudden wind , or mist , or the like ; for the same Gunner may perhaps easily kill a Bird sitting in a bush , or hopping upon the ground . The like may be said of Diseases , Physicians , and Medicines ; for some diseases have such sudden alterations , by the sudden changes of motions , that a wise Physician will not , nor cannot venture to apply so many several medicines so suddenly as the alteration requires ; and shall therefore Physicians be condemned ? and not onely condemned for what cannot be helped by reason of the variety of irregular motions , but what cannot be helped in Nature ? For some diseases are so deadly , as no art can cure them , when as otherwise Physicians with good and proper medicines , have , and do as yet rescue more people from death , then the Laws do from ruine . Nay , I have known many that have been great enemies to Physick , die in the flower of their age , when as others which used themselves to Physick , have lived a very long time . But you may say , Country-people and Labourers , take little or no Physick , and yet grow most commonly old , whereas on the contrary , Great and rich Persons take much Physick , and do not live so long as the common sort of men doth . I answer : It is to be observed , first , that there are more Commons , then Nobles , or Great and rich persons ; and there is not so much notice taken of the death of a mean , as of a noble , great , or rich person ; so that for want of information or knowledg , one may easily be deceived in the number of each sort of persons . Next , the Vulgar sort use laborious exercises , and spare diet ; when as noble and rich persons are most commonly lazie and luxurious , which breeds superfluities of humors , and these again breed many distempers : For example , you shall find few poor men troubled with the Gout , Stone , Pox , and the like diseases , nor their Children with Rickets ; for all this cometh by luxury , and no doubt but all other diseases are sooner bred with luxury , then temperance ; but whatsoever is superfluous , may , if not be taken away , yet mediated with lenitive and laxative medicines . But as for Physicians , surely never age knew any better , in my opinion , then this present , and yet most of them follow the rules of the Schools , which are such as have been grounded upon Reason , Practice , and Experience , for many ages : Wherefore those that will wander from the Schools , and follow new and unknown ways , are , in my opinion , not Orthodoxes , but Hereticks in the Art of Physick . But to return to your Author , give me leave , Madam , to consider what his opinions are concerning the Purging of Choler ; Come on , says he to the Schools a a In his Treatise of Fevers , c. 5. , Why doth that , your Choler following with so swift an efflux , stink so horribly , which but for one quarter of an hour before did not stink ? To which it may be answered , That though humors may not stink in themselves , yet the excrements mixt with the humors may stink ; also the very passing thorow the excrements will cause a strong savour . But your Author thinks , That by passing through so suddenly , the humors cannot borrow such a smell of stinking dung from the Intestines . Truly , 't is easily said , but hardly proved , and the contrary is manifest by putting clear , pure water into a stinking vessel , which straightway is corrupted with an ill smell . He talks also of Vitriol dissolved in Wine , which if it be taken , presently provokes vomit ; but if after drinking it , any one shall drink thereupon a draught of Ale or Beer , or Water , &c. he indeed shall suffer many stools , yet wholly without stink . I answer : This expresses Vitriol to be more poysonous , by taking away the natural savour of the bowels , then Scammony , Coloquintida , Manna , Cassia , Sena , Rhubarb , &c. to all which your Author is a great enemy ; and it is well known to experienced Physicians , that Medicines prepared by the art of fire are more poysonous and dangerous then natural drugs ; nay , I dare say , that many Chymical Medicines , which are thought to be Cordials , and have been given to Patients for that purpose , have proved more poysonous then any Purging Physick . Again your Author says , It is worthy of Lamentation , that Physicians would have loosening things draw out one humor , and not another , by selection or choyce . My answer is , That natural drugs and simples are as wise in their several operations , as Chymists in their artificial distillations , extractions , sublimations , and the like ; but it has long been observed by Physicians , that one simple will work more upon one part of the body , then upon another ; the like may be said of humors . But give me leave to tell you , Madam , that if your Author believes magnetick or attractive cures ( as he doth , and in whose behalf he makes very long discourses ) he doth in this opinion contradict himself . He may say , perhaps , There is no such thing as what Physicians name humors . But grant there be none , yet he cannot deny that there are offensive juices , or moveable substances made by evil , as irregular digestions , which may be troublesom and hurtful to the nature of the body . Or perchance he will say , There are such humors , but they are beneficial and not offensive to the nature of the body . I answer : Then he must make an agreement with every part of the body , not to make more of these humors then is useful for the body . Also he mentions some few that took Purging Physick , and died . Truly so they might have done without taking it : but he doth not tell , how many have died for want of proper and timely Purges . In truth , Madam , 't is an easie thing to find fault , but not so easie to mend it . And as for what he speaks of the weighing of those humors and excrements , which by purging were brought out of some Princes body , and how much by the Schools rules remained , and of the place which should maintain the remainder ; I onely say this , that all the several sorts of juices , humors , or moveable substances in a body , do not lie in one place , but are dispersed , and spread all about and in several parts and places in the body ; so that the several Laxative medicines do but draw them together , or open several parts , that they may have freedom to travel with their chief Commanders , which are the Purging medicines . But your Author says , the Loadstone doth not draw rust . And I say , no more do Purging drugs draw out pure Matter : for it may be as natural for such medicines to draw or work onely upon superfluities , that is , corrupted , or evil-affected humors , juices or moveable substances , as for the Loadstone to draw Iron ; and so it may be the property of Purges to draw onely the rust of the body , and not the pure metal , which are good humors . But few do consider or observe sufficiently the variety of Natures actions , and the motions of particular natural Creatures , which is the cause they have no better success in their cures . And so leaving them to a more diligent inquisition and search into Nature , and her actions , I rest ,

I Find your Author to be as great an enemy to Issues , Cauteries , Clysters , and the like , as he is to Blood-letting and Purging ; especially to Issues , which he counts to be blasphemous against the Creator , and blames much the Schools for prescribing them . But concerning Blood-letting and Purging , I have declared my opinion in my former Letters ; and if you desire my judgment of Clysters and Issues , I must needs tell you , that it is well known these many ages , that in such diseases which lie in the guts , and cause pain in the head , and stop the ureteres , Clysters have been very beneficial , but wise Physicians do not prescribe them , unless upon necessity : As for example ; if the disease in the Guts proceed from cold or wind , they prescribe a Sack-Clyster , with oyl of Walnuts ; and if the disease in the guts proceed from a sharp or bitter humor , then they prescribe Milk , or Posset , sweetned with Sugar : the same if the guts be too full of excrements or slime . But in case of diseases in the head or stomack , they prescribe attractive Clysters , to wit , such as draw down from the upper into the lower parts , wherein the Physical drugs are ; and if the guts be too dry , or dryer then their nature requires , they prescribe moistening Clysters , such as have not onely wetting , but slimy qualities . And surely Clysters properly and timely applyed , are a safe , speedy , easie and profitable medicine , and far more safe then Chymical Salts , Tartars , Spirits , or the like . Next concerning Issues and Cauteries , your Author , I say , is so much against them , as he counts them a blasphemy ; for says he a a Of Cauteries . , I have beheld always an implicite blasphemy in a Cautery , whereby they openly accuse the Creator of insufficiency in framing the emunctories ; for I have bidden above a thousand Issues to be filled up with flesh . Also , That which God hath made whole and entire , that it might be very good , seems to the Schools , that it should be better if it be kept wounded . Truly , Madam , in my opinion , it is no blasphemy at all , neither directly nor indirectly , to make Issues , but a meer superstition to believe the contrary , viz. that they are blasphemy , and a great folly not to make them when need requires it to the preservation of ones health . God has made our body whole and intire , says your Author : by which he will prove that no holes must be made in the body to let out excrementious matter , and therefore he thinks that body to be whole and intire which is without an Issue , when as yet our bodies have numerousissues , which are the pores of the skin , to let out sweat ; and therefore if he counts that body not to be whole and intire that has issues , then no humane body is intire . Certainly , no Artificial Issue will make the body maimed , but it will nevertheless continue whole and intire although it has Issues . He says it is Blasphemy ; But how will he prove it ? Surely not by the Scripture ; and if not by the Scripture , then it is a blasphemy according to his own brain and fancy . 'T is true , God gave no express Command to make Issues ; but according to your Author , God did never create Diseases , and so there was no need either to make such Issues in bodies as to let out distempered Matter , or to give any command for them ; but we might as well say , we must not use any Physick , because it is not so natural to man as food , and serves not for the nourishment of the body , but onely to keep off , or drive out diseases : Also no stone must be cut , but man must rather indure torment and death . But setting aside this superstitious doctrine of your Author , it is evident enough , and needs no proof , that Cancers , Fistula's , Wenns , Eating-evils , Madness , Fevers , Consumptions , Rheumes , Pleurisies , and numerous other diseases , are not better cured then by Issues , or making of wounds , either by Lancets , Pen-knifes , Scissers , Rasors , Corrosives , Causticks , Leeches , or the like . And although your Author says , That that Matter which proceeds from , or out of an Issue , is made in the lips of the wound , and not in the body ; for it cannot possibly drain or draw out any moisture , either from within or between the skin and the flesh , having no passages : Yet if this were so , how come Fistula's , Cancers , and the like diseases , to have passages from within the body to the exterior parts , so , as to make a wound , out of which much sharp and salt humor issues ? which humor certainly is not made in the lips of the wound , but in the body : Also whence comes the humor that makes the Gout ? For though the swelling and inflammation will sometimes appear exteriously , yet after some time those tumors and humors retire back into the body from whence they did flow ; but he might as well say that Pit-falls or Sluces do not drain Land from a superfluity of Water , as that Issues do not drain the body of superfluous humors . Wherefore I am absolutely of opinion , that the Practice of the Schools is the best and wifest Practice , as well in making Issues , letting blood , Purging by Siege or Vomits , as any other means used by them ; for by Issues I have seen many cured , when no other medicines would do any good with them ; and letting blood , I am confident , hath rescued more lives , then the Universal Medicine , could Chymists find it out , perchance would do . So also Clysters and Vomits , skilfully applied , have done great benefits to the life of men ; for every part and member hath its peculiar way to be purged and cleansed ; for example , Clysters principally cleanse the Guts , Purges the Stomack , Vomits the Chest , Sneezing the Head , Bleeding the Veins , and Issues drain the whole body of naughty humors : All which remedies , properly and timely used , keep the body from being choak'd with superfluities . ' There are several other ways of cures besides for several diseases , but I leave those to learned and skilful Physicians , who know best how and when to use them to the benefit and health of their Patients , although your Author finds much fault with them , and blames them for suffering men to die miserably ; but God has given power to Nature to make certain dissolutions , although uncertain diseases , and uncertain remedies . Neither hath she in her power to give Immortal Life to particular Creatures , for this belongs to God alone , and therefore no Universal Medicine will keep out death , or prolong life further then its thread is spun , which I doubt is but a Chymaera , and an impossible thing , by reason there are not onely so many different varieties in several diseases , but in one and the same disease , as no Universal remedy would do any good . But your Author is much pleased with Paradoxes , and Paradoxes are not certain Truths : Wherefore it is better , in my judgment , to follow the old approved and practised way of the Schools , grounded upon Experience and Reason , then his Paradoxical Opinions . To which Schools , as your Author is a great Enemy , so I am a great Friend , as well as ,

I Approve well of your Authors opinion a a Of Fevers , Ch. 12. , That Drink ought not to be forbidden in Fevers ; but yet I would not allow so much as to drown and oppress the Patients life , but onely so much as to refresh and moisten him ; and therefore the best way is to drink little and often . But as for Wine , which your Author commends in Fevers , I am utterly against it , unless the Fever proceed from a cold or crude cause , otherwise cooling Ptisans are most beneficial to those that are sick of a continual Fever , which for the most part is a general Fever throughout the whole body , one part infecting the other , until they be all infected , like as in the Plague . And to let you know the proof of it ; when I was once sick beyond the Seas , I sent for a Doctor of Physick who was an Irish-man : and hearing of some that knew him , and his practice , that he was not successful in his Cures , but that his Patients most commonly died , I asked him what he used to prescribe in such or such diseases ? where amongst the rest , as I remember , he told me , That he allowed his Patients to drink Wine in a Fever . I thought he was in a great error , and told him my opinion , that though Wine might be profitable , perhaps , to some few , yet for the most part it was very hurtful and destructive , alledging another famous Physician in France , Dr. Davison , who used in continual Fevers , to prescribe onely cooling Ptisan , made of a little Barley , and a great quantity of Water , so thin as the Barley was hardly perceived , and a spoonfull of syrup of Limmon put into a quart of the said Ptisan ; but in case of a Flux , he ordered some few seeds of Pomegranats to be put into it , and this cold Ptisan was to be the Patients onely drink : Besides , once in Twenty four hours he prescribed a couple of potched Eggs , with a little Verjuice , and to let the Patient blood , if he was dry and hot ; I mean dry exteriously , as from sweat ; and that either often or seldom , according as occasion was found : Also he prescribed two grains of Laudanum every night , but neither to give the Patient meat nor drink two hours before and after : Which advice and Practice of the mentioned Physician concerning Fevers , with several others , I declared to this Irish Doctor , and he observing this rule , cured many , and so recovered his lost esteem and repute . But your Author being all for Wine , and against cooling drinks , or Julips , in hot Fevers , says , That cooling means are more like to death , to cessation from motion , and to defect ; but heat from moderate Wine is a mean like unto life . To which I answer , first , That cold , or cooling things , are as active as hot or heating things ; neither is death more cold then hot , nor life more hot then cold ; for we see that Frost is as active and strong as burning heat ; and Water , Air , and Earth , are as full of life , as Fire ; and Vegetables , Minerals , and Elements , have life as well as Animals : But we , feeling a Man's flesh cold when he is dissolving from an Animal , think death is cold ; and seeing he was hot before the same alteration , say , Life is hot : Also finding an animal , when it is dissolving , to be without external local Motion , we say it is dead ; and when it hath as yet this local motion before its alteration , we call it alive ; which certainly is not proper . Next I say , that a wise Man when his house is fired , will fling or squirt water upon it , to quench it , and take out all moveables lest they should increase the flame ; likewise he will make vent for the flame to issue forth . But perchance your Author may say , that Fevers are not hot . Truly , in my opinion , he might say as well that Fire is cold . Again : he may say , That although the effect be hot , yet the cause is cold . I answer : That in some diseases , the effects become so firmly rooted , and so powerfull , that they must be more look'd upon then the cause : for such variety there is in Nature , that oftentimes , that which was now an effect , turns to be a cause , and again a cause an effect : For example ; A cold cause often produces a hot effect , and this hot effect becomes again a cause of a cold effect : Which variation is not onely a trouble , but a great obstruction to wise Physicians ; for Nature hath more varieties in diseases , then Physicians have remedies , And as for drink , if Fevers be neither hot , nor dry , nor require drink for want of moisture ; then I see no reason why drink should be urged , and those Physicians blamed that forbid it ; for if thirst proceed from an evil digestion , drink will rather weaken the stomack ; for heat and driness draw soon away the drink in the stomack , and putting much into a weak stomack doth rather hurt then good . But if necessity require it , then I approve rather of raw and crude Water , then of hot inflaming Wiue . And so taking my leave , I rest ,

IN your Authors Treatise of Fevers , I find one Chapter a a Ch. 14. whose Inscription is , A Perfect Curing of all Fevers , wherein he declares the secrets of the Cures of Fevers , consisting all in Chymical Medicines . But considering , that if all Fevers could be cured by such Medicines , then all Physicians would strive to obtain them ; I can hardly believe ( by your Authors favour ) that any such perfect curing of all Fevers can be effected , but that your Authors prescriptions , if they should come to the tryal , might fail as well as any other . Likewise he mentions a Medicine of Paracelsus , named Diaceltesson , or the Coraline Secret ; which , he says , cures radically the Gout no less then Fevers : Which if so , I wonder why so many Great , Noble and Rich Persons , groan so much under the pains of the Gout ; certainly it is not for want of cost to have them prepared , nor for want of an ingenious and experienced Chymist ; for this age doth not want skilful workmen in that Art , nor worthy and wise Physicians ; which if they knew such soveraign medicines , would soon apply them to their Patients ; but I suppose that they finding their effects to be less then the cost and labour bestowed upon them , forbear to use them . Moreover , he mentions b b In the Ch. named Butler . another remedy for most diseases , by him call'd Driff , prepared also by the Art of Chymistry ; but I believe all those remedies will not so often cure , as fail of cure , like as the Sympathetical Powder ; for if there were such soveraign medicines that did never fail of a successful effect , certainly men being curious , inquisitive , and searching , would never leave till they had found them out . Also amongst Vegetables , the herb Chameleon and Arsmart are in great request with your Author ; For , says he , they by their touching alone , do presently take away cruel diseases , or at leastwise ease them . Which if so , I wonder that there is not more use made of them , and they held in greater esteem then they are ; Also that your Author doth not declare the vertue of them , and the manner and way how , and in what diseases to use them , for the benefit of his neighbour , to which end , he says , all his labours and actions are directed ? But again , your Author confirms , as an Eye-witness , That the bone of the arm of a Toad presently has taken away the Tooth-ach at the first co-touching . Which remedy , if it was constant , few , in my opinion , would suffer such cruel pains , and cause their teeth to be drawn out , especially if sound . Likewise of the mineral Electrum or Amber of Paracelsus , he affirms a a Ch. Of the manner of entrance of things darted into the body . to have seen , that hung about the neck , it has freed those that were persecuted by unclean spirits , and that many simples have done the like effects ; but surely , Madam , I cannot be perswaded that the Devil should be put away so easily ; for he being a Spirit , will not be chased by corporeal means , but by spiritual , which is Faith , and Prayer ; and the cure of dispossessing the Devil belongs to Divines , and not to Natural Philosopers or Physicians . But though exterior remedies , as Amulets , Pomanders , and the like , may perform sometimes such effects as to cure or preserve from some diseases , yet they are not ordinary and constant , but meerly by chance . But there are more false remedies then true ones , and if one remedy chance to work successfully with one distempered person , it may fail of its success applyed to others in the same kind of distemper ; nay , it may cure perhaps one and the same person of a distemper once , and in the return of the same disease effect little or nothing ; witness those remedies that are applyed in Agues , Tooth-aches , and the like , especially Amulets ; for one and the same disease in several persons , or in one and the same person at several times , may vary and change so often , and proceed from so different causes , and be of so different tempers , and have such different motions , as one and the same medicine can do no good : And what would the skill of Physicians be , if one remedy should cure all diseases ? Why should they take so much pains in studying the various causes , motions , and tempers of diseases , if one medicine had a general power over all ? Nay , for what use should God have created such a number of different simples , Vegetables , and Minerals , if one could do all the business ? Lastly , your Author rehearses a a Ch. Of things injected into the body . some strange examples of Child-bearing Women , who having seen terrible and cruel sights , as Executions of Malefactors , and dismembring of their bodies , have brought forth monstrous births , without heads , hands , arms , leggs , &c. according to the objects they had seen . I must confess , Madam , that all Creatures are not always formed perfect ; for Nature works irregularly sometimes , wherefore a Child may be born defective in some member or other , or have double members instead of one , and so may other animal Creatures ; but this is nevertheless natural , although irregular to us : but to have a Child born perfect in the womb , and the lost member to be taken off there , and so brought forth defective , as your Author mentions , cannot enter my belief ; neither can your Author himself give any reason , but he makes onely a bare relation of it ; for certainly , if it was true , that the member was chopt , rent or pluckt off from the whole body of the Child , it could not have been done without a violent shock or motion of the Mother , which I am confident would never have been able to endure it ; for such a great alteration in her body would of necessity , besides the death of the Child , have caused a total dissolution of her own animal parts , by altering the natural animal motions : But , as I said above , those births are caused by irregular motions , and are not frequent and ordinary ; for if upon every strange sight , or cruel object , a Child-bearing-woman should produce such effects , Monsters would be more frequent then they are . In short , Nature loves variety , and this is the cause of all strange and unusual natural effects ; and so leaving Nature to her will and pleasure , my onely delight and pleasure is to be ,

YOur Author reproving the Schools , that they forbid Salt to some diseased persons , as pernicious to their health : Good God , says he a a Of the disease of the Stone , c. 3. , how unsavoury are the Schools , and how unsavoury do they bid us to be ! But I suppose the Schools do not absolutely forbid all diseased persons to abstein from salt , but onely not to use it excessively , or too frequently ; for experience proves , that salt meats have not onely increased , but caused diseases , as the Stone , the Gout , Sciatica , Fistula's , Cancers , sore Eyes , sore Throats , and the like : I do not say , that those diseases are always bred with the excess of salt diets ; for diseases of one and the same kind , may be bred variously ; but this hath been observed , that whosoever is affected with such diseases , shall after a salt meal find himself in more pain then before ; wherefore a constant or common salt diet cannot but be hurtful . Neither are those persons that feed much on salt meats , or use strong drinks , take number for number , so healthful or long-lived , as those that are temperate and abstaining . Next , your Author a a Ch. Of the reason or consideration of diet . bewails The shameful simplicity of those , that give their Patients Leaf-Gold , Pearls , and bruised or powderd pretious Stones , as Cordials , in fainting fits , and other distempers : For , says he , they may be dissolved , but not altered ; wherefore they cannot produce any powerful effect to the health of the Patient . Truly , Madam , I am not of his mind ; for were it that those remedies or cordials could not be transchanged , yet their vertues may nevertheless be very beneficial to the fick : For example ; a man that is assaulted by enemies , or by chance is fallen into a deep Pit , or is ready to be strangled , and in all not able to help himself , yet by the help of another man , may be rescued and freed from his danger , and from death , using such means as are able to release him , which either by drawing his Sword against his ememies , or by throwing a rope down into the Pit , and haling him out , or by cutting the rope by which he hung , may save him , and yet neither the man , nor any of his Instruments , as Sword , Rope , Knife , and the like , need to be transchanged . The like may be said of the aforementioned medicines or remedies ; which if they be not transchangeable , yet they may nevertheless do such operations , as by their natural active qualities and proprieties to over-power the irregular motions in the natural parts of the body of the Patient ; for many diseases proceed more from irregular motions then irregular parts : and although there is no motion without matter , yet one and the same matter may have divers and various changes of motions , and moving parts will either oppose or assist each other without transchanging . And truly , Madam , I wonder that your Author doth condemn such Cordials made of Leaf-gold , Pearls , powdered precious Stones , or the like , and yet verily believe , that Amber , Saphires , Emeraulds , Beads , Bracelets , &c. outwardly applied or worn , can cure more then when inwardly taken ; surely , if this be so , they cure more by Faith , then by Reason . But it seems your Author regulates the actions of Nature to the artificial actions of his Furnace , which although sometimes they produce wonderful effects , yet not such as Nature doth ; for if they cure one , they commonly kill ten ; nay , the best of their Medicine is so dangerous , as it ought not to be applied but in desperate cases : Wherefore Wise Physicians must needs be Provident and Cautious when they use them . And so leaving them , I rest ,

I Will not dispute your Authors opinion concerning the Plague of Men , which he says , doth not infect In the Plague-grave , ch. 17. Beasts , neither doth the plague of Beasts infect Men ; but rather believe it to be so : for I have observed , that Beasts infect onely each other , to wit , those of their own kind , as Men do infect other Men. For example : the Plague amongst Horses continues in their own kind , and so doth the Plague amongst Sheep ; and for any thing we know , there may be a plague amongst Vegetables , as well as amongst Animals , and they may not onely infect each other , but also those Animals that do feed on those infectious Vegetables : so that Infections may be caused several ways ; either by inbreathing and attracting or sucking in the Poyson of the Plague , or by eating and converting it into the substance of the body ; for some kinds of poyson are so powerful , as to work onely by way of inbreathing . Also some sorts of Air may be full of infection , and infect many Men , Beasts , Birds , Vegetables , and the like ; for Infections are variously produced , Internally as well as Externally , amongst several particular Creatures ; for as the Plague may be made internally , or within the body of a particular Creature , without any exterior infection entring from without into the body , so an external Infection again may enter many several ways into the body . And thus there be many contagious diseases caused meerly by the internal motions of the body , as by fright , terror , conceit , fancy , imagination , and the like , and many by the taking of poysonous matter from without into the body ; but all are made by the natural motions or actions of animate matter , by which all is made that is in Nature , and nothing is new , as Solomon says ; but what is thought or seems to be new , is onely the variation of the Motions of this old Matter , which is Nature . And this is the reason that not every Age , Nation , or Creature , has always the like diseases ; for as all the actions of Nature vary , so also do diseases . But to speak of the Plague , although I am of opinion , that the Plague of Beasts doth not infect Men , unless they be eaten ; nor the plague of Men , Beasts ; yet Magistrates do wisely in some places , that in the beginning of the plague of Men , they command Dogs and Cats to be kill'd , by reason , as your Author saith , The skins and flesh of Brutes may be defiled with our Plague , and they may be pestiferous contagions unto us . I will add one thing more , which doth concern the Poyson of Measels , whereof your Author is saying a a Ch. Call'd , The Lunar Tribute . , That it is onely proper to humane kind . What kind of Measles he means , I know not ; but certainly Hogs are often affected with that disease , as is vulgarly known ; but whether they be different diseases in their kinds , and proceed from different motions , I will let others inquire . And so I rest ,

COncerning the disease of the Stone , your Author seems to be of an opinion , That the stone in the Bladder , and the stone in the Kidnies , are not made after one and the same manne : For , says he a a Of the Stone , ch 6. See the ch. called , A Numero-Critical Paradox of supplies . , The Bladder and the same Vrine in number procreates a duelech of another condition , then that which is made in the Kidney . And truly , Madam , it may be so ; for there are several ways or modes in irregularities , as well as regularities , and not every kind is alike , no not every Particular , but there is some difference between them : Wherefore , it may very well be , that the corporeal motions that make the stone in the Kidneys , are not just alike to those that make the stone in the Bladder ; and as each sort of stone is different , so their particular causes ought to be different ; but this is to be observed , that generally all diseases which produce hardness , are made by contracting , condensing and retenting motions , and therefore the remedies of them must be dilating , rarifying and dissolving . Next your Author says , The Stone is not bred by heat , but heat is rather an effect of the stone ; neither is a certain muscilage , or a slimy , snivelly Phlegme the cause or matter of the stone , but the stone is the cause of the phlegme . But , in my judgment , it seems more probable , that a slimy matter is more proper for a stone to be made of , then that a stone should make slime , except it be in its dissolution ; that is , when the stone , as in its generation or production it did change from a slimy or liquid substance to a stone by condensing and contracting motions , doth , by dilating and rarifying motions , dissolve again into such a liquid and slimy body . I will not say always , to wit , that the stone must needs be resolved into a slimy matter , but oftentimes it may be so . Neither can I absolutely affirm that either heat or cold onely is the cause of a stone ; for some may be produced by hot , and some by cold contractions and densations , there being as many several sorts of stones as there are of other Creatures : But this is to be well noted , that as some sorts of hot contractions do make stones , so some sorts of hot dilations do dissolve them : The like of cold contractions and dilations . Again : your Author speaking of the womb wherein the stone is made ; Every generated thing or being , says he , must of necessity have a certain place or womb where it is produced ; for there must needs be places wherein things may be made before they are bred . I answer : As there is not any body without place , nor any place without body , so the womb is not the place of the body generated , neither before nor after its generation , no more then a man can be said to be in a room when he is not there , but every body carries its place along with it . Moreover , concerning the voiding of bloody Urine , which happens sometimes in the disease of the Stone , my opinion is , That it doth not always proceed from the Stone , but many times from the breaking or voluntary opening of some Veins . But as for the cure of the disease of the Stone your Author a a Ch. 7. is pleased to affirm , That no disease is incurable , and so neither the disease o● the Stone ; For he himself has cured many of the Stone to which they had been obedient for some years . Indeed , Madam , I fear his words are more cheerful then effectual ; however it may be possible , if the Kidneys be no ways impaired , or the Bladder hurt ; but if there be some such imperfection in either or both , then it is as much , in my opinion , as to say , Man can do more then Nature doth : Neither can I believe , that then any of your Authors Chymical preparations , as Aroph , Ludus , Alkahest , and the like , if they were to be had , would do any good , no nor Daucus , or wild Carrot-seed , if the disease be as yet curable , will prove an effectual remedy for it , although your Author is pleased to relate an example of a man , to whom it did much good ; for I can affirm the contrary by other the like Examples , that it never did any good to those that used it ; nor the liquor of the Birch-tree , whose vertue and efficacy I do not believe to be so great as your Author describes a a Ch. 8. : But for the stoppage of Urine , Marsh-mallow and oyl of Almonds , which he despises , I approve to be good , and better then any of his Unknown , Chymical Secrets ; for those Chymical Medicines , as he himself confesses , are hard to be had , especially Alkahest , which is onely to be obtained by a Particular favour from Heaven , and is rather a supernatural Gift , then a natural remedy . But your Author doth wisely , to commend such remedies as can never , or with great difficulty be obtained , and then to say that no disease is incurable . And so leaving him to his unknown secrets , and those to them that will use them , I am resolved to adhere to the Practice of the Schools , which I am confident will be more beneficial to the health of ,

YOur Author speaking of the Gout , and of that kind of Gout which is called Hereditary , says , It consists immediately in the Spirit of Life . First , as for that which is called an Hereditary Disease , propagated from Parents upon their Children ; my opinion is , That it is nothing else but the same actions of the animate matter , producing the same effect in the Child as they did in the Parent : For example ; the same motions which made the Gout in the Parent , may make the same disease in the Child ; but every Child has not his Parents diseases , and many Children have such diseases as their Parents never had ; neither is any disease tied to a particular Family by Generation , but they proceed from irregular motions , and are generally in all Mankind ; and therefore properly there is no such thing as an hereditary propagation of diseases ; for one and the same kind of disease may be made in different persons , never a kin to one another , by the like motions ; but because Children have such a neer relation to their Parents by Generation , if they chance to have the same diseases with their Parents , men are apt to conclude it comes by inheritance ; but we may as well say , that all diseases are hereditary ; for there is not any disease in Nature but is produced by the actions of Nature's substance ; and if we receive life and all our bodily substance by Generation from our Parents , we may be said to receive diseases too ; for diseases are inherent in the matter or substance of Nature , which every Creature is a part of , and are real beings made by the corporeal motions of the animate matter , although irregular to us ; for as this matter moves , so is Life or Death , Sickness or Health , and all natural effects ; and we consisting of the same natural matter , are naturally subject as well to diseases as to health , according as the Matter moves . Thus all diseases are hereditary in Nature ; nay , the Scripture it self confirms it , informing us , that diseases , as well as death , are by an hereditary propagation derived from Adam upon all Posterity . But as for the Gout , your Authors doctrine is a a Of the disease of the Stone . c. 9. , That Life is not a body , nor proper to a body , nor of the off-spring of corporeal Proprieties b b Of the subject of inhering of diseases in the point of life . , but a meer No-thing ; and that the Spirit of Life c c Of the Spirit of Life . is a real being , to wit , the arterial blood resolved by the Ferment of the heart into salt air , and enlightned by life , and that the Gout doth immediately consist in this spirit of life . All which how it doth agree , I cannot conceive ; for that a real being should be enlightned by Nothing , and be a spirit of Nothing , is not imaginable , nor how the Gout should inhabit in the spirit of life ; for then it would follow , that a Child , as soon as it is brought forth into the world , would be troubled with the Gout , if it be as natural to him as life , or have its habitation in the Spirit of Life . Also your Author is speaking of an Appoplexy in the head , which takes away all sense and motion . But surely , in my opinion , it is impossible that all sense and motion should be out of the head ; onely that sense and motion , which is proper to the head , and to the nature of that Creature , is altered to some other sensitive and rational motions , which are proper to some other figure ; for there is no part or particle of matter that has not motion and sense . I pray consider , Madam , is there any thing in Nature that is without motion ? Perchance you will say , Minerals ; but that is proved otherwise ; as for example , by the sympathetical motion between the Loadstone and Iron , and between the Needle and the North , as also by the operation of Mercury , and several others : Wherefore there is no doubt , but all kinds , sorts and particulars of Creatures have their natural motions , although they are not all visible to us , but not such motions as are made by Gas , or Blas , or Ideas , &c. but corporeal sensitive and rational motions , which are the actions of Natural Matter . You may say , Some are of opinion , that Sympathy and Antipathy are not Corporeal motions . Truly , whosoever says so , speaks no reason ; for Sympathy and Antipathy are nothing else but the actions of bodies , and are made in bodies ; the Sympathy betwixt Iron and the Loadstone is in bodies ; the Sympathy between the Needle and the North is in bodies ; the Sympathy of the Magnetick powder is in bodies . The truth is , there is no motion without a body , nor no body without motion . Neither doth Sympathy and Antipathy work at distance by the power of Immaterial Spirits , or rays , issuing out of their bodies , but by agreeable or disagreeable corporeal motions ; for if the motions be agreeable , there is Sympathy ; if disagreeable , there is Antipathy ; and if they be equally found in two bodies , then there is a mutual Sympathy or Antipathy ; but if in one body onely , and not in the other , there is but Sympathy or Antipathy on one side , or in one Creature . Lastly , concerning swoonings or fainting fits , your Authors opinion is , that they proceed from the stomack : Which I can hardly believe ; for many will swoon upon the sight of some object , others at a sound , or report , others at the smell of some disagreeable odour , others at the taste of some or other thing that is not agreeable to their nature , and so forth : also some will swoon at the apprehension or conceit of something , and some by a disorder or irregularity of motions in exterior parts . Wherefore , my opinion is , that swoonings may proceed from any part of the body , and not onely from the stomack . But , Madam , I being no Physicianess may perhaps be in an error , and therefore I will leave this discourse to those that are thorowly learned and practised in this Art , and rest satisfied that I am ,

YOur Author a a In the ch. call'd Butler . is inquiring whether some cures of diseases may be effected by bare co-touchings ; and I am of his opinion , they may ; for co-touchings of some exterior objects may cause alterations of some particular motions in some particular parts of matter , without either transferring their own motions into those parts , ( for that this is impossible , I have heretofore declared ) or without any corporeal departing from their own parts of matter into them , and alterations may be produced both in the motions and figures of the affected parts : but these cures are not so frequent as those that are made by the entring of medicines into the diseased parts , and either expel the malignant matter , or rectifie the irregular and disordered motions , or strengthen the weak , or reduce the straying , or work any other ways according to the nature and propriety of their own substance , and the disposition of the distempered parts : Nevertheless , those cures which are performed exteriously , as to heal inward affects by an outwad bare co-touching , are all made by natural motions in natural substances , and not by Non-being , substanceless Ideas , or spiritual Rays ; for those that will cure diseases by Non-beings , will effect little or nothing ; for a disease is corporeal or material , and so must the remedies be , there being no cure made but by a conflict of the remedy with the disease ; and certainly , if a non-being fight against a being , or a corporeal disease , I doubt it will do no great effect ; for the being will be too strong for the non-being : Wherefore my constant opinion is , that all cures whatsover , are perfected by the power of corporeal motions , working upon the affected parts either interiously or exteriously , either by applying external remedies to external wounds , or by curing internal distempers , either by medicines taken internally , or by bare external co-touchings . And such a remedy , I suppose , has been that which your Author speaks of , viz. a stone of a certain Irish-man , which by a meer external contact hath cured all kinds of diseases , either by touching outwardly the affected parts , or by licking it but with the tip of the Tongue , if the disease was Internal : But if the vertue of the Stone was such , as your Author describes , certainly , what man soever he was that possessed such a jewel , I say , he was rather of the nature of the Devil , then of man , that would not divulge it to the general benefit of all mankind ; and I wonder much , that your Author , who otherwise pretends such extraordinary Devotion , Piety , and Religiousness , as also Charity , viz. that all his works he has written , are for the benefit of his neighbour , and to detect the errors of the Schools meerly for the good of man , doth yet plead his cause , saying , That secrets , as they are most difficultly prepared , so they ought to remain in secret forever in the possession of the Privy Councel , what Privy Counsels he means , I know not ; but certainly some are more difficult to be spoken to , or any thing to be obtained from , then the preparation of a Physical Arcanum . However , a general good or benefit ought not to be concealed or kept in privy Councels , but to be divulged and publickly made known , that all sorts of People , of what condition , degree , or Nation soever , might partake of the general blessing and bounty of God . But , Madam , you may be sure , that many , who pretend to know Physical secrets , most commonly know the least , as being for the most part of the rank of them that deceive the simple with strange tales which exceed truth ; and to make themselves more authentical , they use to rail at others , and to condemn their skill , onely to magnifie their own : I say , many , Madam , as I have observed , are of that nature , especially those , that have but a superficial knowledge in the Art of Physick ; for those that are thorowly learned , and sufficiently practised in it , scorn to do the like ; which I wish may prosper and thrive by their skill . And so I rest ,

YOur Author is pleased to relate a story of one that died suddenly , and being disfected , there was not the least sign of decay or disorder found in his body . Ch. 61. called , The Preface . But I cannot add to those that wonder , when no sign of distemper is found in a man's body after he is dead ; because I do not believe , that the subtillest , learnedst , and most practised Anatomist , can exactly tell all the Interior Government or motions , or can find out all obscure and invisible passages in a man's body ; for concerning the motions , they are all altered in death , or rather in the dissolution of the animal figure ; and although the exterior animal figure or shape doth not alter so soon , yet the animal motions may alter in a moment of time ; which sudden alteration may cause a sudden death , and so the motions being invisible , the cause of death cannot be perceived ; for no body can find that which is not to be found , to wit , animal motions in a dead man ; for Nature hath altered these motions from being animal motions to some other kind of motions , she being as various in dissolutions , as in productions , indeed so various , that her ways cannot be traced or known thorowly and perfecty , but onely by piece-meals , as the saying is , that is , but partly : Wherefore man can onely know that which is visible , or subject to his senses ; and yet our senses do not always inform us truly , but the alterations of grosser parts are more easily known , then the alterations of subtil corporeal motions , either in general , or in particular ; neither are the invisible passages to be known in a dead Carcass , much less in a living body . But , I pray , mistake me not , when I say , that the animal motions are not subject to our exterior senses ; for I do not mean all exterior animal motions , nor all interior animal motions ; for though you do see no interior motion in an animal body , yet you may feel some , as the motion of the Heart , the motion of the Pulse , the motion of the Lungs , and the like ; but the most part of the interior animal motions are not subject to our exterior senses ; nay , no man , he may be as observing as he will , can possibly know by his exterior senses all the several and various interior motions in his own body , nor all the exterior motions of his exterior parts : and thus it remains still , that neither the subtillest motions and parts of matter , nor the obscure passages in several Creatures , can be known but by several parts ; for what one part is ignorant of , another part is knowing , and what one part is knowing , another part is ignorant thereof ; so that unless all the Parts of Infinite Matter were joyned into one Creature , there can never be in one particular Creature a perfect knowledg of all things in Nature . Wherefore I shall never aspire to any such knowledg , but be content with that little particular knowledg , Nature has been pleased to give me , the chief of which is , that I know my self , and especially that I am ,

MADAM , Your constant Friend , and faithful Servant .
XLIV . MADAM ,

I Perceive you are desirous to know the cause , Why a man is more weak at the latter end of a disease then at the beginning , and is a longer time recovering health , then loosing health ; as also the reason of relapses and intermissions ? First , as for weakness and strength , my opinion is , they are caused by the regular and irregular motions in several parts , each striving to over-power the other in their conflict ; and when a man recovers from a disease , although the regular motions have conquered the irregular , and subdued them to their obedience , yet they are not so quite obedient as they ought , which causes weakness : Neither do the regular motions use so much force in Peace , as in War ; for though animate matter cannot lose force , yet it doth not always use force ; neither can the parts of Nature act beyond their natural power , but they do act within their natural power ; neither do they commonly act to the utmost of their power . And as for Health , why it is sooner lost then recovered ; I answer , That it is easier to make disorders then to rectifie them : as for example , in a Common-wealth , the ruines of War are not so suddenly repaired , as made . But concerning Relapses and Intermissions of diseases , Intermissions are like truces or cessations from War for a time ; and Relapses are like new stirs or tumults of Rebellion ; for Rebels are not so apt to settle in peace as to renew the war upon slight occasions ; and if the regular motions of the body be stronger , they reduce them again unto obedience . But diseases are occasioned many several ways ; for some are made by a home Rebellion , and others by forreign enemies , and some by natural and regular dissolutions , and their cures are as different ; but the chief Magistrates or Governors of the animal body , which are the regular motions of the parts of the body , want most commonly the assistance of forreign Parts , which are Medicines , Diets , and the like ; and if there be factions amongst these chief Magistrates , or motions of the parts of the body , then the whole body suffers a ruine . But since there would be no variety in Nature , nor no difference between Natures several parts or Creatures , if her actions were never different , but always agreeing and constant , a war or rebellion in Nature cannot be avoided : But , mistake me not , for I do not mean a war or rebellion in the nature of substance of Matter , but between the several parts of Matter , which are the several Creatures , and their several Motions ; for Matter being always one and the same in its nature , has nothing to war withal ; and surely it will not quarrel with its own Nature . Next you desire to know , that if Nature be in a Perpetual motion , Whence comes a duration of some things , and a Tiredness , Weariness , Sluggishness , or Faintness ? I answer , first , That in some bodies , the Retentive motions are stronger then the dissolving motions ; as for example , Gold , and Quicksilver or Mercury ; the separating and dissolving motions of Fire have onely power to melt and rarifie them for a time , but cannot alter their nature : so a Hammer , or such like instrument , when used , may beat Gold , and make it thin as a Cobweb , or as dust , but cannot alter its interior nature : But yet this doth not prove it to be either without motion , or to be altogether unalterable , and not subject to any dissolution ; but onely that its retentive motions are too strong for the dissolving motions of the Fire , which by force work upon the Gold ; and we might as well say , that Sand , or an Earthen Vessel , or Glass , or Stone , or any thing else , is unalterable , and will last eternally , if not disturbed . But some of Natures actions are as industrious to keep their figures , as others are to dissolve , or alter them ; and therefore Retentive motions are more strong and active in some figures , then dissolving motions are in others , or producing motions in other Figures . Next , as for Tiredness , or Faintness of motions , there is no such thing as tiredness or faintness in Nature , for Nature cannot be tired , nor grow faint , or sick , nor be pained , nor die , nor be any ways defective ; for all this is onely caused through the change and variety of the corporeal motions of Nature , and her several parts ; neither do irregular motions prove any defect in Nature , but a prudence in Natures actions , in making varieties and alterations of Figures ; for without such motions or actions , there could not be such varieties and alterations in Nature as there are : neither is slackness of some motions a defect , for Nature is too wise to use her utmost force in her ordinary works ; and though Nature is infinite , yet it is not necessary she should use an infinite force and power in any particular act . Lastly , you desire my opinion , Whether there be motion in a dead animal Creature . To which , I answer : I have declared heretofore , that there is no such thing as death in Nature , but what is commonly named death , is but an alteration or change of corporeal motions , and the death of an animal is nothing else but the dissolving motions of its figure ; for when a man is dying , the motions which did formerly work to the consistence of his figure do now work to the dissolution of his figure , and to the production of some other figures , changing and transforming every part thereof ; but though the figure of that dead animal is dissolved , yet the parts of that dissolved figure remain still in Nature although they be infinitely changed , and will do so eternally , as long as Nature lasts by the Will of God ; for nothing can be lost or annihilated in Nature . And this is all , Madam , that I can answer to your questions , wherein , I hope , I have obeyed your commands , according to the duty of ,

MADAM , Your faithful Friend and humble Servant .
XLV . MADAM ,

I Have thus far discharged my duty , that according to your commands , I have given you my judgment of the works of those four famous Philosophers of our age , which you did send me to peruse , and have withal made reflexions upon some of their opinions in Natural Philosophy , especially those , wherein I did find them dissent from the Ground and Principles of my own Philosophy . And since by your leave I am now publishing all those Letters which I have hitherto written to your concerning those aforesaid Authors , and their Works , I am confident I shall not escape the censures of their followers ; But , I shall desire them , that they will be pleased to do me this Justice , and to examine first my opinions well , without any partiality or wilful misinterpretation of my sence , before they pass their censure : Next , I desire them to consider , That I have no skill in School-learning , and therefere for want of terms of Art may easily chance to slip , or at least , not express my opinions so clearly as my readers expected ; However , I have done my endeavour , and to my sense and reason they seem clear and plain enough , especially as I have expressed them in those Letters I have sent you ; for concerning my other Work , called Philosophical Opinions , I must confess , that it might have been done more exactly and perspicuously , had I been better skilled in such words and expressions as are usual in the Schools of Philosophers ; and therefore , if I be but capable to learn names and terms of Art , ( although I find my self very untoward to learn , and do despair of proving a Scholar ) I will yet endeavour to rectifie that work , and make it more intelligible ; for my greatest ambition is to express my conceptions so , that my Readers may understand them : For which I would not spare any labour or pains , but be as industrious as those that gain their living by their work ; and I pray to God , that Nature may give me a capacity to do it . But as for those that will censure my works out of spite and malice , rather then according to justice , let them do their worst ; for if God do but bless them , I need not to fear the power of Nature , much less of a part of Nature , as Man . Nay , if I have but your Ladiships approbation , it will satisfie me ; for I know you are so wife and just in your judgment , that I may safely rely upon it : For which I shall constantly and unfeignedly remain as long as I live ,

SECT. IV.
I. MADAM ,

I Perceive , you take great delight in the study of Natural Philosophy , since you have not onely sent me some Authors to peruse , and give my judgment of their opinions , but are very studious your self in the reading of Philosophical Works : and truly , I think you cannot spend your time more honourably , profitably , and delightfully , then in the study of Nature , as to consider how Variously , Curiously , and Wisely , she acts in her Creatures ; for if the particular knowledg of a man's self be commendable , much more is the knowledg of the general actions of Nature , which doth lead us to the knowledg of our selves . The truth is , by the help of Philosophy our Minds are raised above our selves , into the knowledg of the Causes of all natural effects . But leaving the commending of this noble study , you are pleased to desire my opinion of a very difficult and intricate argument in Natural Philosophy , to wit , of Generation , or Natural Production . I must beg leave to tell you , first , that some ( though foolishly ) believe , it is not fit for Women to argue upon so subtil a Mystery : Next , there have been so many learned and experienced Philosophers , Physicians , and Anatomists , which have treated of this subject , that it might be thought a great presumption for me , to argue with them , having neither the learning nor experience by practice which they had : Lastly , There are so many several ways and manners of Productions in Nature , as it is impossible for a single Creature to know them all : For there are Infinite variations made by self-motion in Infinite Matter , producing several Figures , which are several Creatures in that same Matter . But you would fain know , how Nature , which is Infinite Matter , acts by self-motion ? Truly , Madam , you may as well ask any one part of your body , how every other part of your body acts , as to ask me , who am but a small part of Infinite Matter , how Nature works . But yet , I cannot say , that Nature is so obscure , as her Creatures are utterly ignorant ; for as there are two of the outward sensitive organs in animal bodies , which are more intelligible then the rest , to wit , the Ear , and the Eye ; so in Infinite Matter , which is the body of Nature , there are two parts , which are more understanding or knowing then the rest , to wit , the Rational and Sensitive part of Infinite Matter ; for though it be true , That Nature , by self-division , made by self-motion into self-figures , which are self-parts , causes a self-obscurity to each part , motion , and figure ; nevertheless , Nature being infinitely wise and knowing , its infinite natural wisdom and knowledg is divided amongst those infinite parts of the infinite body : and the two most intelligible parts , as I said , are the sensitive and rational parts in Nature , which are divided , being infinite , into every Figure or Creature ; I cannot say equally divided , no more , then I can say , all creatures are of equal shapes , sizes , properties , strengths , quantities , qualities , constitutions , semblances , appetites , passions , capacities , forms , natures , and the like ; for Nature delights in variety , as humane sense and reason may well perceive : for seldom any two creatures are just alike , although of one kind or sort , but every creature doth vary more or less . Wherefore it is not probable , that the production or generation of all or most Creatures , should be after one and the same manner or way , for else all Creatures would be just alike without any difference . But this is to be observed , that though Nature delights in variety , yet she doth not delight in confusion , but , as it is the propriety of Nature to work variously , so she works also wisely ; which is the reason , that the rational and sensitive parts of Nature , which are the designing and architectonical parts , keep the species of every kind of Creatures by the way of Translation in Generation , or natural Production ; for whatsoever is transferred , works according to the nature of that figure or figures from whence it was transferred , But mistake me not ; for I do not mean always according to their exterior Figure , but according to their interior Nature ; for different motions in one and the same parts of matter , make different figures , wherefore much more in several parts of matter and changes of motion ; But , as I said , Translation is the chief means to keep or maintain the species of every kind of Creatures , which Translation in natural production or generation , is of the purest and subtilest substances , to wit , the sensitive and rational , which are the designing and architectonical parts of Nature . You may ask me , Madam , what this wise and ingenious Matter is . I answer : It is so pure , subtil , and self-active , as our humane shares of sense and reason cannot readily or perfectly perceive it ; for by that little part of knowledg that a humane creature hath , it may more readily perceive the strong action then the purer substance ; for the strongest action of the purest substance is more perceivable then the matter or substance it self ; which is the cause , that most men are apt to believe the motion , and to deny the matter , by reason of its subtilty ; for surely the sensitive and rational matter is so pure and subtil , as not to be expressed by humane sense and reason . As for the rational-matter , it is so pure , fine , and subtil , that it may be as far beyond lucent matter , as lucent matter is beyond gross vapours , or thick clouds ; and the sensitive matter seems not much less pure : also there is very pure inanimate matter , but not subtil and active of it self ; for as there are degrees in the animate , so there are also degrees in the inanimate matter ; so that the purest degree of inanimate matter comes next to the animate , not in motion , but in the purity of its own degree ; for it cannot change its nature so , as to become animate , yet it may be so pure in its own nature , as not to be perceptible by our grosser senses . But concerning the two degrees of animate Matter , to wit , the sensitive and rational , I say that the sensitive is much more acute then Vitriol , Aqua-fortis , Fire , or the like ; and the rational much more subtil and active then Quicksilver , or Light , so as I cannot find a comparison fit to express them , onely that this sensitive and rational self-moving Matter is the life and soul of Nature ; But by reason this Matter is not subject to our gross senses , although our senses are subject to it , as being made , subsisting and acting through the power of its actions , we are not apt to believe it , no more then a simple Country-wench will believe , that Air is a substance , if she neither hear , see , smell , taste , or touch it , although Air touches and surrounds her : But yet the effects of this animate matter prove that there is such a matter ; onely , as I said before , this self-moving matter causing a self-division as well as a general action , is the cause of a self-obscurity , which obscurity causes doubts , disputes , and inconstancies in humane opinions , although not so much obscurity , as to make all Creatures blindfold , for surely there is no Creature but perceives more or less . But to conclude , The Rational degree of Matter is the most intelligible , and the wisest part of Nature , and the Sensitive is the most laborious and provident part in Nature , both which are the Creators of all Creatures in Infinite Matter ; and if you intend to know more of this Rational and Sensitive Matter , you may consult my Book of Philosophy , to which I refer you . And so taking my leave for the present , I rest ,

MADAM , Your Faithful Friend and Servant .
II. MADAM ,

I Understand by your last , that you have read the Book of that most learned and famous Physician and Anatomist , Dr. Harvey , which treats of Generation ; and in the reading of it , you have mark'd several scruples , which you have framed into several questions concerning that subject , to which you desire my answer . Truly , Madam , I am loth to imbarque my self in this difficult argument , not onely for the reasons I have given you heretofore , but also that I do not find my self able enough to give you such a satisfactory answer as perhaps you do expect . But since your Commands are so powerful with me , that I can hardly resist them , and your Nature so good that you easily pardon any thing that is amiss , I will venture upon it according to the strength of my Natural Reason , and endeavour to give you my opinion as well and as clearly as I can . Your first question is ; Whether the action of one or more producers be the onely cause of Natural Production or Generation , without imparting or transferring any of their own substance or Matter . I answer : The sole co-action of the Producers may make a change of exterior forms or figures , but not produce another Creature ; for if there were not substance or matter , as well as action , both transferred together , there would not be new Creatures made out of old Matter , but every production would require new Matter , which is impossible , if there be but one Matter , and that infinite ; and certainly , humane sense and reason may well perceive , that there can be but one Matter , for several kinds of Matter would make a confusion ; and thus if new Creatures were made onely by substanceless motion , it would not onely be an infinite trouble to Nature , to create something out of nothing perpetually , but , as I said , it would make " a confusion amongst all Nature's works , which are her several Parts or Creatures . But by reason there is but one Matter , which is Infinite and Eternel , and this Matter has self-motion in it , both Matter , and Motion must of necessity transmigrate , or be transferred together without any separation , as being but one thing , to wit , Corporeal Motion . 'T is true , one part of animate or self-moving Matter , may without Translation move , or rather occasion other parts to move ; but one Creature cannot naturally produce another without the transferring of its corporeal motions . But it is well to be observed , that there is great difference between the actions of Nature ; for all actions are not generating , but some are patterning , and some transforming , and the like ; and as for the transforming action , that may be without translation , as being nothing else but a change of motions in one and the same part or parts of Matter , to wit , when the same parts of Matter do change into several figures , and return into the same figures again . Also the action of Patterning is without Translation ; for to pattern out , is nothing else but to imitate , and to make a figure in its own substance or parts of Matter like another figure . But in generation every producer doth transfer both Matter and Motion , that is , Corporeal Motion into the produced ; and if there be more producers then one , they all do contribute to the produced ; and if one Creature produces many Creatures , those many Creatures do partake more or less of their producer . But you may say , If the producer transfers its own Matter , or rather its own corporeal motions into the produced , many productions will soon dissolve the producer , and he will become a sacrifice to his off-spring . I answer ; That doth not follow : for as one or more Creatures contribute to one or more other Creatures ; so other Creatures do contribute to them , although not after one and the same manner or way , but after divers manners or ways ; but all manners and ways must be by translation to repair and assist ; for no Creature can subsist alone and of it self , but all Creatures traffick and commerce from and to each other , and must of necessity do so , since they are all parts of the same Matter : Neither can Motion subsist without Matter , nor quit Matter , nor act without Matter , no more , then an Artificer can work without materials , and without self-motion Matter would be dead and useless ; Wherefore Matter and Motion must upon necessity not onely be inseparable , but be one body , to wit , corporeal motion ; which motion by dividing and composing its several parts , and acting variously , is the cause of all Production , Generation , Metamorphosing , or any other thing that is done in Nature . But if , according to your Author , the sole action be the cause of Generation without transferring of substance , then Matter is useless , and of none or little effect ; which , in my opinion , is not probable .

Your second question is , Whether the Production or Generation of animals is as the Conceptions of the Brain , which the Learned say are Immaterial ? I answer : The Conceptions of the Brain , in my opinion , are not Immaterial , but Corporeal ; for though the corporeal motions of the brain , or the matter of its conceptions , is invisible to humane Creatures , and that when the brain is dissected , there is no such matter found , yet that doth not prove , that there is no Matter , because it is not so gross a substance as to be perceptible by our exterior senses : Neither will your Authors example hold , that as a builder erects a house according to his conception in the brain , the same happens in all other natural productions or generations ; for , in my opinion , the house is materially made in the brain , which is the conception of the builder , although not of such gross materials , as Stone , Brick , Wood , and the like , yet of such matter as is the Rational Matter , that is , the house when it is conceived in the brain , is made by the rational corporeal figurative motions of their own substance or degree of Matter ; But if all Animals should be produced by meer fancies , and a Man and a Woman should beget by fancying themselves together in copulation , then the produced would be a true Platonick Child ; But if a Woman being from her Husband should be so got with Child , the question is , whether the Husband would own the Child ; and if amorous Lovers ( which are more contagious for appetite and fancy then Married persons ) should produce Children by Immaterial contagions , there would be more Children then Parents to own them .

Your third question is , Whether Animals may not be produced , as many Diseases are , by contagion ? I answer : Although contagions may be made at a distance , by perception ; yet those diseases are not begotten by immaterial motions , but by the rational and sensitive corporeal motions , which work such diseases in the body of a Creature , by the association of parts , like as the same disease is made in another body : Neither are diseases always produced after one and the same manner , but after divers manners ; whereas animals are produced as animals , that is , after one natural and proper way ; for although all the effects in particular be not alike , yet the general way or manner to produce those effects is the same : As for example ; there is no other way to produce a fruitful Egg , but by a Cock and a Hen ; But a Contagious disease , as the small-Pox , or the like , may be produced by the way of Surfeits or by Conceit , which may cause the sensitive corporeal parts , through the irregular motions of the rational corporeal parts , to work and produce such a disease , or any other ways . But neither a disease , nor no creature else can be produced without matter , by substanceless motion ; for wheresoever is motion , there is also matter , matter and motion being but one thing .

Your fourth question is , Whether an Animal Creature is perfectly shaped or formed at the first Conception ? I answer : If the Creature be composed of many and different parts , my opinions is , it cannot be . You may say , That if it hath not all his parts produced at once , there will be required many acts of generation to beget or produce every part , otherwise the producers would not be the Parents of the produced in whole , but in part . I answer : The Producer is the designer , architect , and founder of the whole Creature produced ; for the sensitive and rational corporeal motions , which are transferred from the producer or producers , joyn to build the produced like to the producer in specie , but the transferred parts may be invisible and insensible to humane Creatures , both through their purity and little quantity , until the produced is framed to some visible degree ; for a stately building may proceed from a small beginning , neither can humane sense tell what manner of building is designed at the first foundation . But you may say , That many Eggs may be made by one act of the producers , to wit , the Cock and the Hen , and those many Eggs may be laid at several times , as also hatched at several times , and become Chickens at several times . I answer ; It may well and easily be so : for the rational and sensitive parts or corporeal motions which were transferred in one act , designed many produced through that one act ; for those transferred corporeal motions , although they have not a sufficient quantity of themselves to make all the produced in their perfect shapes at once , yet they are the chief designer , architect and founder of all that are to be produced ; for the corporeal motions which are transferred , joyn with those they are transferred to , and being associates , work to one design , the sensitive being the architect , the rational the designer , which together with the inanimate parts of matter , can never want materials , neither can the materials want labourers ; for the degrees of matter are inseparable , and do make but one body or substance . Again you may say , That some parts of Matter may produce another Creature not like to the producer in its species , as for example , Monsters . I answer , That is possible to be done , but yet it is not usual ; for Monsters are not commonly born , but those corporeal motions which dwell in one species , work according to the nature of the same species ; and when the parts of Matter are transferred from Creature to Creature , that is , are separated from some parts , and joyned to other pars of the same species , and the same nature ; those transferred parts of matter , although invisible in quantity , by reason of their purity and subtilty , begin the work of the produced according to its natural species , and the labourers in other parts of matter work to the same end ; just as it is in the artificial building of a house , where the house is first designed by the Architect , or Master , and then the labourers work not after their own fancy , ( else it would not be the same house that was designed , nor any uniformity in it ) but according to the architects or surveyors design ; so those parts of matter or corporeal motions that are transferred from the producer , are like the architect , but the labourers or workmen are the assisting and adjoyning parts of matter . But you will say , How comes it , that many creatures may be made by one or two ? I answer : As one owner or two partners may be the cause of many buildings , so few or more transferred rational and sensitive corporeal motions may make and produce as many creatures as they can get materials and labourers ; for if they get one , they get the other , by reason the degrees of matter , viz. animate and inanimate , are inseparably mixt , and make but one body or substance ; and the proof of it is , that all animals are not constant in the number of their off-spring , but sometimes produce more , and sometimes fewer , and sometimes their off-spring is less , and sometimes larger , according to the quantity of matter . Again you may say , That in some Creatures there is no passage to receive the transferred matter into the place of the architecture . I answer : That all passages are not visible to humane sense ; and some humane Creatures have not a sufficient humane reason to conceive , that most of Natures works are not so gross as to be subject to their exterior senses ; but as for such parts and passages , whether exterior or interior , visible or invisible , as also for copulation , conception , formation , nourishment , and the like in Generation , I leave you to Physicians and Anatomists . And to conclude this question , we may observe , that not any animal Creatures shape dissolveth in one instant of time , but by degrees ; why should we believe then , that Animals are generated or produced in their perfect shape in one instant of time , and by one act of Nature ? But sense and reason knows by observation , that an animal Creature requires more time to be generated , then to be dissolved , like as an house is sooner and with less pains pull'd down , then built up . Your Fifth question is , Whether Animals are not generated by the way of Metamorphosing ? To which I answer , That it is not possible that a third Creature can be made without translation of corporeal motions ; and since Metamorphosing is onely a change of motions in the same parts of Matter , without any translation of corporeal motions , no animal Creature can be produced or generated by the way of Metamorphosing . Your Sixth question is , Whether a whole may be made out of a part ? I answer : There is no whole in Nature , except you will call Nature her self a whole ; for all Creatures are but parts of Infinite Matter . Your Seventh question is , Whether all Animals , as also Vegetables , are made or generated by the way of Eggs ? I have said heretofore , That it is not probable , that different sorts , nay , different kinds of Creatures , should all have but one manner or way of production ; for why should not Nature make different ways of productions , as well as different Creatures ? And as for Vegetables , if all their Seeds be likened unto Eggs , then Eggs may very well be likened to Seeds ; which if so , then a Peas-cod is the Hen , and the Peas in the Cod is the cluster of Eggs : the like of ears of Corn. And those animals that produce but one creature or seed at a time , may be like the kernel of a Nut , when the shell is broke , the creature comes forth . But how this will agree with your Author , who says , that the creature in the shell must make its own passage , I cannot tell ; for if the Nut be not broken by some external means or occasion , the kernel is not like to get forth . And as for humane Eggs , I know not what to answer ; for it is said , that the first Woman was made of a mans ribb ; but whether that ribb was an egg , I cannot tell . And why may not Minerals and Elements be produced by the way of Eggs as well as Vegetables and Animals ? Nay , why may not the whole World be likened unto an Egg ? Which if so , the two Poles are the two ends of the Egg ; and for the Elements , the Yolk is the Fire , the White , the Water ; the Film , the Air ; and the Shell it self will very well serve for the Earth : But then it must first be broken , and pounded into one lump or solid mass , and so swim or sink into the midst of the liquid parts , as to the Center ; and as for the several faetuses in this great Egg , they are the several Creatures in it . Or it might be said , that the Chaos was an Egg , and the Universe , the Chicken . But leaving this fimilizing , it is like , that some studious Men may by long study upon one part of the body , conceive and believe that all other parts are like that one part ; like as those that have gazed long upon the Sun , all they see for a time , are Suns to them ; or like as those which having heard much of Hobgoblins , all they see are Hobgoblins , their fancies making such things . But , Madam , to make a conclusion also of this question , I repeat what I said before , viz. that all Creatures have not one way of production ; and as they have not all one way of production , so they have neither one instant of time either for perfection or dissolution , but their perfection and dissolution is made by degrees . Your Eighth question is , Whether it may not be , that the sensitive and rational corporeal motions in an Egg do pattern out the figure of the Hen and Cock , whilest the Hen sits upon the Egg , and so bring forth Chickens by the way of patterning ? I answer : The action of patterning , is not the action of Generation ; for as I said heretofore , the actions of Nature are different , and Generation must needs be performed by the way of translation , which translation is not required in the action of Patterning ; but according as the Producers are , which transfer their own matter into the produced , so is the produced concerning its species ; which is plainly proved by common examples ; for if Pheasants , or Turky , or Goose-eggs , be laid under an ordinary Hen , or an ordinary Hens-egg be laid under a Pheasant , Turky , or Goose , the Chickens of those Eggs will never be of any other species then of those that produced the Egg ; for an ordinary Hen , if she sit upon Pheasants , Turky , or Goose-eggs , doth not hatch Chickens of her own species , but the Chickens will be of the species either of the Pheasant , or Turky , or Goose , which did at first produce the Egg ; which proves , that in Generation , or Natural production , there is not onely required the action of the Producers , but also a Transferring of some of their own parts to form the produced . But you may say , What doth the sitting Hen contribute then to the production of the Chicken ? I answer : The sitting Hen doth onely assist the Egg in the production of the Chicken , as the Ground doth the Seed . Your Ninth question is , Concerning the Soul of a particular Animal Creature , as whether it be wholly of it self , and subsists wholly in and by it self ? But you must give me leave first to ask you what Soul you mean , whether the Divine , or the Natural Soul , for there is great difference betwixt them , although not the least that ever I heard , rightly examined and distinguished ; and if you mean the Divine Soul , I shall desire you to excuse me , for that belongs to Divines , and not to Natural Philosophers ; neither am I so presumptuous as to intrench upon their sacred order . But as for the Natural Soul , the Learned have divided it into three parts , to wit , the Vegetative , Sensitive , and Rational Soul ; and according to these three Souls , made three kinds of lives , as the Vegetative , Sensitive , and Rational Life . But they might as well say , there are infinite bodies , lives , and souls , as three ; for in Nature there is but one life , soul , and body , consisting all of one Matter , which is corporeal Nature . But yet by reason this life and soul is material , it is divided into numerous parts , which make numerous lives and souls in every particular Creature ; for each particular part of the rational self-moving Matter , is each particular soul in each particular Creature , but all those parts considered in general , make but one soul of Nature ; and as this self-moving Rational Matter hath power to unite its parts , so it hath ability or power to divide its united parts . And thus the rational soul of every particular Creature is composed of parts , ( I mean parts of a material substance ; for whatsoever is substanceless and incorporeal , belongs not to Nature , but is Supernatural ; ) for by reason the Infinite and Onely matter is by self-motion divided into self-parts , not any Creature can have a soul without parts ; neither can the souls of Creatures subsist without commerce of other rational parts , no more then one body can subsist without the assistance of other bodies ; for all parts belong to one body , which is Nature : nay , if any thing could subsist of it self , it were a God , and not a Creature : Wherefore not any Creature can challenge a soul absolutely to himself , unless Man , who hath a divine soul , which no other Creature hath . But that which makes so many confusions and disputes amongst learned men is , that they conceive , first , there is no rational soul but onely in man ; next , that this rational soul in every man is individable . But if the rational soul is material , as certainly to all sense and reason it is , then it must not onely be in all material Creatures , but be dividable too ; for all that is material or corporeal hath parts , and is dividable , and therefore there is no such thing in any one Creature as one intire soul ; nay , we might as well say , there is but one Creature in Nature , as say , there is but one individable natural soul in one Creature . Your Tenth question is , Whether Souls are producible , or can be produced ? I answer : in my opinion , they are producible , by reason all parts in Nature are so . But mistake me not ; for I do not mean that any one part is produced out of Nothing , or out of new matter ; but one Creature is produced by another , by the dividing and uniting , joyning and disjoyning of the several parts of Matter , and not by substanceless Motion out of new Matter . And because there is not any thing in Nature , that has an absolute subsistence of it self , each Creature is a producer , as well as a produced , in some kind or other ; for no part of Nature can subsist single , and without reference and assistance of each other , or else every single part would not onely be a whole of it self , but be as a God without controle ; and though one part is not another part , yet one part belongs to another part , and all parts to one whole , and that whole to all the parts , which whole is one corporeal Nature . And thus , as I said before , productions of one or more creatures , by one or more producers , without matter , meerly by immaterial motions , are impossible , to wit , that something should be made or produced out of nothing ; for if this were so , there would consequently be an annihilation or turning into nothing , and those Creatures , which produce others by the way of immaterial motions , would rather be as a God , then a part of Nature , or Natural Matter . Besides , it would be an endless labour , and more trouble to create particular Creatures out of nothing , then a World at once ; whereas now it is easie for Nature to create by production and transmigration ; and therefore it is not probable , that any one Creature hath a particular life , soul , or body to it self , as subsisting by it self , and as it were precised from the rest , having its own subsistence without the assistance of any other ; nor is it probable , that any one Creature is new , for all that is , was , and shall be , till the Omnipotent God disposes Nature otherwise .

As for the rest of your questions , as whether the Sun be the cause of all motions , and of all natural productions ; and whether the life of a Creature be onely in the blood , or whether it have its beginning from the blood , or whether the blood be the chief architect of an animal , or be the seat of the soul ; sense and reason , in my opinion , doth plainly contradict them ; for concerning the blood , if it were the seat of the Soul , then in the circulation of the blood , if the Soul hath a brain , it would become very dizzie by its turning round ; but perchance some may think the Soul to be a Sun , and the Blood the Zodiack , and the body the Globe of the Earth , which the Soul surrounds in such time as the Blood is flowing about . And so leaving those similizing Fancies , I 'le add no more , but repeat what I said in the beginning , viz. that I rely upon the goodness of your Nature , from which I hope for pardon , if I have not so exactly and solidly answered your desire ; for the argument of this discourse being so difficult , may easily lead me into an error , which your better judgment will soon correct ; and in so doing you will add to those favours for which I am already ,

MADAM , Your Ladiships most obliged Friend and humble Servant .
III. MADAM ,

You thought verily , I had mistaken my self in my last , concerning the Rational Souls of every particular Creature , because I said , all Creatures had numerous Souls ; and not onely so , but every particular Creature had numerous Souls . Truly , Madam , I did not mistake my self , for I am of the same opinion still ; for though there is but one Soul in infinite Nature , yet that soul being dividable into parts , every part is a soul in every single creature , were the parts no bigger in quantity then an atome . But you ask whether Nature hath Infinite souls ? I answer : That Infinite Nature is but one Infinite body , divided into Infinite parts , which we call Creatures ; and therefore it may as well be said , That Nature is composed of Infinite Creatures or Parts , as she is divided into Infinite Creatures or Parts ; for Nature being Material , is dividable , and composable . The same may be said of Nature's Soul , which is the Rational part of the onely infinite Matter , as also of Nature's Life , which is the sensitive part of the onely Infinite self-moving Matter ; and of the Inanimate part of the onely . Infinite Matter , which I call the body for distinction sake , as having no self-motion in its own nature , for Infinite Material Nature hath an Infinite Material Soul , Life , and Body . But , Madam , I desire you to observe what I said already , viz. that the parts of Nature are as apt to divide , as to unite ; for the chief actions of Nature are to divide , and to unite ; which division is the cause , that it may well be said , every particular Creature hath numerous souls ; for every part of rational Matter is a particular Soul , and every part of the sensitive Matter is a particular Life ; all which , mixed with the Inanimate Matter , though they be Infinite in parts , yet they make but one Infinite whole , which is Infinite Nature ; and thus the Infinite division into Infinite parts is the cause , that every particular Creature hath numerous Souls , and the transmigration of parts from , and to parts , is the reason , that not any Creature can challenge a single soul , or souls to it self ; the same for life . But most men are unwilling to believe , that Rational Souls are material , and that this rational Matter is dividable in Nature ; when as humane sense and reason may well perceive , that Nature is active , and full of variety ; and action , and variety cannot be without motion , division , and composition : but the reason that variety , division , and composition , runs not into confusion , is , that first there is but one kind of Matter ; next , that the division and composition of parts doth ballance each other into a union in the whole . But , to conclude , those Creatures which have their rational parts most united , are the wisest ; and those that have their rational parts most divided , are the wittiest ; and those that have much of this rational matter , are much knowing ; and those which have less of this rational matter , are less knowing ; and there is no Creature that hath not some ; for like as all the parts of a humane body are indued with life , and soul ; so are all the parts of Infinite Nature ; and though some parts of Matter are not animate in themselves , yet there is no part that is not mixt with the animate matter ; so that all parts of Nature are moving , and moved . And thus , hoping I have cleared my self in this point , to your better understanding , I take my leave , and rest ,

MADAM , Your faithful Friend and Servant .
IV. MADAM ,

IN the Works of that most famous Philosopher and Mathematician of our age Gal. which you thought worth my reading , I find , he discourses much of upwards and downwards , backwards and forwards ; but to tell you really , I do not understand what he means by those words , for , in my opinion , there is properly no such thing as upwards , downwards , backwards , or forwards in Nature , for all this is nothing else but natural corporeal motions , to which in respect of some particulars we do attribute such or such names ; for if we conceive a Circle , I pray where is upwards and downwards , backwards and forwards ? Certainly , it is , in my opinion , just like that , they name Rest , Place , Space , Time , &c. when as Nature her self knows of no such things , but all these are onely the several and various motions of the onely Matter . You will say , How can Rest be a motion ? I answer : Rest is a word which expresses rather mans ignorance then his knowledg ; for when he sees , that a particular Creature has not any external local motion perceptible by his sight , he says it resteth , and this rest he calls a cessation from motion , when as yet there is no such thing as cessation from motion in Nature ; for motion is the action of natural Matter , and its Nature is to move perpetually ; so that it is more probable for motion to be annihilated , then to cease . But you may say , It is a cessation from some particular motion . I answer : You may rather call it an alteration of a particular motion , then a cessation ; for though a particular motion doth not move in that same manner as it did before , nevertheless it is still there , and not onely there , but still moving ; onely it is not moving after the same manner as it did move heretofore , but has changed from such a kind of motion to another kind of motion , and being still moving it cannot be said to cease : Wherefore what is commonly called cessation from motion , is onely a change of some particular motion , and is a mistake of change for rest . Next , I find in the same Author a long discourse of circular and strait motions ; to wit , That they are simple motions , and that all others are composed out of them , and are mixt motions ; Also , That the Circular Motion is perfect , and the Right imperfect ; and that all the parts of the world , if moveable of their own nature , it is impossible , that their motions should be Right , or any other then Circular : That a Circular motion is never to be gotten naturally , without a preceding right motion : That a Right motion cannot naturally be perpetual : That a Right motion is impossible in the World well ordered : and the like . First , I cannot conceive why natural Matter should use the Circle-figure more then any other in the motions of her Creatures ; for Nature , which is Infinite Matter , is not bound to one particular motion , or to move in a Circle more then any other figure , but she moves more variously then any one part of hers can conceive ; Wherefore it is not requisite that the natural motions of natural bodies should be onely Circular . Next , I do not understand , why a Circular Motion cannot be gotten naturally without a precedent right motion ; for , in my opinion , corporeal motions may be round or circular , without being or moving straight before ; and if a straight line doth make a circle , then an imperfect figure makes a perfect ; but , in my opinion , a circle may as well make a straight line , as a strait line a circle ; except it be like a Gordian knot , that it cannot be dissolved , or that Nature may make some corporeal motions as constant as she makes others inconstant , for her motions are not alike in continuance and alteration . And as for right motion , that naturally it cannot be perpetual ; my opinion is , that it cannot be , if Nature be finite ; but if Nature be infinite , it may be : But the circular motion is more proper for a finite , then an infinite , because a circle-figure is perfect and circumscribed , and a straight line is infinite , or at least producible in infinite ; and there may be other worlds in infinite Nature , besides these round Globes perceptible by our sight , which may have other figures ; for though it be proper for Globes or Spherical bodies to move round , yet that doth not prove , that Infinite Matter moves round , or that all worlds must be of a Globous figure ; for there may be as different Worlds , as other Creatures . He says , That a Right motion is impossible in the World well ordered ; But I cannot conceive a Right motion to be less orderly then a Circular in Nature , except it be in some Particulars ; but oftentimes that , which is well ordered in some cases , seems to some mens understandings and perceptions ill ordered in other cases ; for man , as a part , most commonly considers but the Particulars , not the Generals , like as every one in a Commonwealth considers more himself and his Family , then the Publick . Lastly , Concerning the simplicity of Motions , as that onely circular and straight motions are simple motions , because they are made by simple Lines ; I know not what they mean by simple Lines ; for the same Lines which make straight and circular figures , may make as well other figures as those ; but , in my opinion , all motions may be called simple , in regard of their own nature ; for they are nothing else but the sensitive and rational part of Matter , which in its own nature is pure , and simple , and moves according to the Nature of each Figure , either swiftly or slowly , or in this or that sort of motion ; but the most simple , purest and subtillest part is the rational part of matter , which though it be mixed with the sensitive and inanimate in one body , yet it can and doth move figuratively in its own matter , without the help or assistance of any other . But I desire you to remember , Madam , that in the compositions and divisions of the parts of Nature , there is as much unity and agreement as there is discord and disagreement ; for in Infinite , there is no such thing , as most , and least ; neither is there any such thing as more perfect , or less perfect in Matter . And as for Irregularities , properly there is none in Nature , for Nature is Regular ; but that , which Man ( who is but a small part of Nature , and therefore but partly knowing ) names Irregularities , or Imperfections , is onely a change and alteration of motions ; for a part can know the variety of motions in Nature no more , then Finite can know Infinite , or the bare exterior shape and figure of a mans body can know the whole body , or the head can know the mind ; for Infinite natural knowledg is corporeal ; and being corporeal , it is dividable ; and being dividable , it cannot be confined to one part onely ; for there is no such thing as an absolute determination or subsistence in parts without relation or dependance upon one another . And since Matter is Infinite , and acts wisely , and all for the best , it may be as well for the best of Nature , when parts are divided antipathetically , as when they they are united sympathetically : Also Matter being Infinite , it cannot be perfect , neither can a part be called perfect , as being a part . But mistake me not , Madam ; for when I say , there is no perfection in Nature , as I do in my Philosophical Opinions * * Part. 1. e. 14. , I mean by Perfection , a finiteness , absoluteness , or compleatness of figure ; and in this sense I say Nature has no perfection by reason it is Infinite ; but yet I do not deny , but that there is a perfection in the nature or essence of Infinite Matter ; for Matter is perfect Matter ; that is , pure and simple in its own substance or nature , as meer Matter , without any mixture or addition of some thing that is not Matter , or that is between Matter and no Matter ; and material motions are perfect motions although Infinite : just as a line may be called a perfect line , although it be endless , and Gold , or other Mettal , may be called perfect Gold , or perfect Metal , although it be but a part . And thus it may be said of Infinite Nature , or Infinite Matter , without any contradiction , that it is both perfect , and not perfect ; perfect in its nature or substance , not perfect in its exterior figure . But you may say , If Infinite Matter be not perfect , it is imperfect , and what is imperfect , wants something . I answer , That doth not follow : for we cannot say , that what is not perfect , must of necessity be imperfect , because there is something else , which it may be , to wit , Infinite ; for as imperfection is beneath perfection , so perfection is beneath Infinite ; and though Infinite Matter be not perfect in its figure , yet it is not imperfect , but Infinite ; for Perfection and Imperfection belongs onely to Particulars , and not to Infinite . And thus much for the present . I conclude , and rest ,

MADAM , Your Ladiships most obliged Friend and humble servant .
V. MADAM ,

The Author , mentioned in my former Letter , . says , That Quietness is the degree of Infinite slowness , and that a moveable body passing from quietness , passes through all the degrees of slowness without staying in any . But I cannot conceive that all the Parts of Matter should be necessitated to move by degrees ; for though there be degrees in Nature , yet Nature doth not in all her Actions move by degrees . You may say , for example , from one to twenty , there are eighteen degrees between One , and Twenty ; and all these degrees are included in the last degree , which is twenty . I answer ; That may be : but yet there is no progress made through all those degrees ; for when a body doth move strong at one time , and the next time after moves weak ; I cannot conceive how any degrees should really be made between . You may say , By Imagination . But this Imagination of degrees , is like the conception of Space and Place , when as yet there is no such thing as Place or Space by it self ; for all is but one body , and Motion is the action of this same body , which is corporeal Nature ; and because a particular body can and doth move after various manners , according to the change of its corporeal motions , this variety of motions man call's Place , Space ; Time , Degrees , &c. considering them by themselves , and giving them peculiar names , as if they could be parted from body , or at least be conceived without body ; for the Conception or Imagination it self is corporeal , and so are they nothing else but corporeal motions . But it seems as if this same Author conceived also motion to be a thing by it self , and that motion begets motion , when he says , That a body by moving grows stronger in motion by degrees , when as yet the strength was in the matter of the body eternally ; for Nature was always a grave Matron , never a sucking Infant : and though parts by dissolving and composing may lose and get acquaintance of each other , yet no part can be otherwise in its nature , then ever it was ; Wherefore change of corporeal motions is not losing nor getting strength or swiftness ; for Nature doth not lose force , although she doth not use force in all her various actions ; neither can any natural body get more strength then by nature it hath , although it may get the assistance of other bodies joyned to it . But swiftness and slowness are according to the several figurative actions of self-moving matter ; which several actions or motions of Nature , and their alterations , cannot be found out by any particular Creature : As for example , the motions of Lead , and the motions of Wood , unless Man knew their several causes ; for Wood , in some cases , may move slower then Lead ; and Lead , in other cases , slower then Wood. Again : the same Author says , That an heavy moveable body descending , gets force enough to bring it back again to as much height . But I think , it might as well be said , That a Man walking a mile , gets as much strength as to walk back that mile ; when 't is likely , that having walked ten miles , he may not have so much strength as to walk back again one mile ; neither is he necessitated to walk back , except some other more powerful body do force him back : for though Nature is self-moving , yet every part has not an absolute power , for many parts may over-power fewer ; also several corporeal motions may cross and oppose as well as assist each other ; for if there were not opposition , as well as agreement and assistance amongst Nature's parts , there would not be such variety in Nature as there is . Moreover , he makes mention of a Line , with a weight hung to its end , which being removed from the perpendicular , presently falls to the same again . To which , I answer : That it is the appetite and desire of the Line , not to move by constraint , or any forced exterior motion ; but that which forces the Line to move from the Perpendicular , doth not give it motion , but is onely an occasion that it moves in such a way ; neither doth the line get that motion from any other exterior body , but it is the lines own motion ; for if the motion of the hand , or any other exterior body , should give the line that motion , I pray , from which doth it receive the motion to tend to its former state ? Wherefore , when the Line moves backwards or forwards , it is not , that the Line gets what it had not before , that is , a new corporeal motion , but it uses its own motion ; onely , as I said , that exterior body is the occasion that it moves after such a manner or way , and therefore this motion of the line , although it is the lines own motion , yet in respect of the exterior body that causes it to move that way , it may be called a forced , or rather an occasioned motion . And thus no body can get motion from another body , except it get matter too ; for all that motion that a body has , proceeds from the self-moving part of matter , and motion and matter are but one thing ; neither is there any inanimate part of matter in Nature , which is not co-mixed with the animate , and consequently , there is no part which is not moving , or moved ; the Animate part of matter is the onely self-moving part , and the Inanimate the moved : not that the animate matter doth give away its own motion to the inanimate , and that the inanimate becomes self-moving ; but the animate , by reason of the close conjunction and commixture , works together with the inanimate , or causes the inanimate to work with it ; and thus the inanimate remains as simple in its own nature , as the animate doth in its nature , although they are mixt ; for those mixtures do not alter the simplicity of each others Nature . But having discoursed of this subject in my former Letters , I take my leave , and rest ,

MADAM , Your faithful Friend and Servant .
VI. MADAM ,

IT seems , my former Letter concerning Motion , has given you occasion to propound this following question to me , to wit , When I throw a bowl , or strike a ball with my hand ; whether the motion , by which the bowl or ball is moved , be the hands , or the balls own motion ? or whether it be transferred out of my hand into the ball ? To which , I return this short answer : That the motion by which ( for example ) the bowl is moved , is the bowls own motion , and not the hands that threw it ; for the hand cannot transfer its own motion , which hath a material being , out of it self into the bowl , or any other thing it handles , touches , or moves ; or else if it did , the hand would in a short time become weak and useless , by losing so much substance , unless new motions were as fast created , as expended . You 'l say , perhaps , that the hand and the bowl may exchange motions , as that the bowls own motion doth enter into the hand , and supply that motion which went out of the hand into the bowl , by a close joyning or touch , for in all things moving and moved , must be a joyning of the mover to the moved , either immediate , or by the means of another body . I answer : That this is more probable , then that the hand should give out , or impart motion to the bowl , and receive none from the bowl ; but by reason motion cannot be transferred without matter , as being both inseparably united , and but one thing ; I cannot think it probable , that any of the animate or self-moving matter in the hand , quits the hand , and enters into the bowl ; nor that the animate matter , which is in the bowl , leaves the bowl , and enters into the hand , because that self-moving substance is not readily prepared for so sudden a Translation or Transmigration . You may say , It may as easily be done as food is received into an animal body and excrement discharged , or as air is taken in , and breath sent out , by the way of respiration ; and that all Creatures are not onely produced from each other , but do subsist by each other , and act by each others assistance . I answer : It is very true , that all Creatures have more power and strength by a joyned assistance , then if every part were single , and subsisted of it self . But as some parts do assist each other , so on the other side , some parts do resist each other ; for though there be a unity in the nature of Infinite Matter , yet there are divisions also in the Infinite parts of Infinite Matter , which causes Antipathy as much as Sympathy ; but they being equal in assistance as well as in resistance , it causes a conformity in the whole nature of Infinite Matter ; for if there were not contrary , or rather , I may say , different effects proceeding from the onely cause , which is the onely matter , there could not possibly be any , or at least , so much variety in Nature , as humane sense and reason perceives there is . But to return to our first argument : You may say , that motion may be transferred out of one body into another , without transferring any of the Matter . I answer : That is impossible , unless motion were that which some call No-thing , but how No-thing can be transferred , I cannot imagine : Indeed no sense and reason in Nature can conceive that which is No-thing ; for how should it conceive that which is not in Nature to be found . You 'l say , perhaps , It is a substanceless thing , or an incorporeal , immaterial being or form . I answer : In my opinion , it is a meer contradiction , to say , a substanceless thing , form , or being , for surely in Nature it cannot be . But if it be not possible that motion can be divided from matter , you may say , that body from whence the motion is transferred , would become less in bulk and weight , and weaker with every act of motion ; and those bodies into which corporeal motion or self-moving matter was received , would grow bigger , heavier , and stronger . To which , I answer : That this is the reason , which denies that there can be a translation of motion out of the moving body into the moved ; for questionless , the one would grow less , and the other bigger , that by loosing so much substance , this by receiving . Nay if it were possible , as it is not , that motion could be transferred without matter , the body out of which it goes , would nevertheless grow weaker ; for the strength lies in the motion , unless you believe , this motion which is transferred to have been useless in the mover , and onely useful to the moved ; or else it would be superfluous in the moved , except you say , it became to be annihilated after it was transferr'd and had done its effect ; but if so , then there would be a perpetual and infinite creation and annihilation of substanceless motion , and how there could be a creation and annihilation of nothing , my reason cannot conceive , neither is it possible , unless Nature had more power then God , to create Nothing , and to annihilate Nothing . The truth is , it is more probable for sense and reason to believe a Creation of Something out of Nothing , then a Creation of Nothing out of Nothing . Wherefore it cannot in sense and reason be , that the motion of the hand is transferr'd into the bowl . But yet I do not say , that the motion of the hand doth not contribute to the motion of the bowl ; for though the bowl hath its own natural motion in it self , ( for Nature and her creatures know of no rest , but are in a perpetual motion , though not always exterior and local , yet they have their proper and certain motions , which are not so easily perceived by our grosser senses . ) nevertheless the motion of the bowl would not move by such an exterior local motion , did not the motion of the hand , or any other exterior moving body give it occasion to move that way ; Wherefore the motion of the hand may very well be said to be the cause of that exterior local motion of the bowl , but not to be the same motion by which the bowl moves . Neither is it requisite , that the hand should quit its own motion , because it uses it in stirring up , or putting on the motion of the bowl ; for it is one thing to use , and another to quit ; as for example , it is one thing to offer his life for his friends service , another to imploy it , and another to quit or lose it . But , Madam , there may be infinite questions or exceptions , and infinite answers made upon one truth ; but the wisest and most probable way is , to rely upon sense and reason , and not to trouble the mind , thoughts , and actions of life , with improbabilities , or rather impossibilities , which sense and reason knows not of , nor cannot conceive . You may say , A Man hath sometimes improbable , or impossible Fancies , Imaginations , or Chymaera's , in his mind , which are No-things . I answer , That those Fancies and Imaginations are not No-things , but as perfectly imbodied as any other Creatures ; but by reason , they are not so grosly imbodied , as those creatures that are composed of more sensitive and inanimate matter , man thinks or believes them to be no bodies ; but were they substanceless figures , he could not have them in his mind or thoughts : The truth is , the purity of reason is not so perspicuous and plain to sense , as sense is to reason , the sensitive matter being a grosser substance then the rational . And thus , Madam , I have answered your proposed question , according to the ability of my Reason , which I leave to your better examination , and rest in the mean while ,

HAving made some mention in my former Letter of the Receiving of Food , and discharging of Excrements , as also of Respiration , which consists in the sucking in of air , and sending out of breath in an animal body ; you desire to know , Whether Respiration be common to all animal Creatures ? Truly , I have not the experience , as to tell you really , whether all animals respire , or not ; for my life being , for the most part , solitary and contemplative , but not active , I please my self more with the motions of my thoughts , then of my senses ; and therefore I shall give you an answer according to the conceivement of my reason onely , which is , That I believe , all animals require Respiration ; not onely those , which live in the air , but those also , which live in waters , and within the earth ; but they do not respire all after one and the same manner ; for the matter which they imbreath , is not every where the same , nor have they all the same organs , or parts , nor the same motions . As for example : Some Creatures require a more thin and rarer substance for their imbreathing or inspiring , then others , and some a more thick and grosser substance then others , according to their several Natures ; for as there are several kinds of Creatures , according to their several habitations or places they live in , so they have each a distinct and several sort of matter or substance for their inspiraration . As for example : Some live in the Air , some upon the face of the Earth , some in the bowels of the Earth , and some in Waters . There is some report of a Salamander , who lives in the Fire ; but it being not certainly known , deserves not our speculation . And , as in my opinion , all animal Creatures require Respiration , so I do verily believe , that also all other kinds of Creatures , besides animals , have some certain manmer of imbreathing and transpiring , viz. Vegetables , Minerals , and Elements , although not after the same way as Animals , yet in a way peculiar and proper to the nature of their own kind . For example : Take away the earth from Vegetables , and they will die , as being , in my opinion , stifled or smothered , in the same manner , as when the Air is taken away from some Animals . Also , take Minerals out of the bowels of the Earth , and though we cannot say , they die , or are dead , because we have not as yet found out the alterative motions of Minerals , as well as of Vegetables , or Animals , yet we know that they are dead from production and increase , for not any Metal increases being out of the Earth . And as for Elements , it is manifest that Fire will die for want of vent ; but the rest of the Elements , if we could come to know the matter ; manner , and ways of their Vital Breathing , we might kill or revive them as we do Fire . And therefore all Creatures , to my Reason , require a certain matter and manner of inspiration and expiration , which is nothing else but an adjoyning and disjoyning of parts to and from parts ; for not any natural part or creature can subsist single , and by it self , but requires assistance from others , as this , and the rest of my opinions in Natural Philosophy , desire the assistance of your favour , or else they will die , to the grief of ,

TH other day I met with the Work of that Learned Author Dr. Ch. which treats of Natural Philosophy ; and amongst the rest , in the Chapter of Place , I found that he blames Aristotle for saying , there are none but corporeal dimensions , Length , Breadth , and Depth in Nature , making besides these corporeal , other incorporeal dimensions which he attributes to Vacuum . Truly , Madam , an incorporeal dimension or extension , seems , in my opinion , a meer contradiction ; for I cannot conceive how nothing can have a dimension or extension , having nothing to be extended or measured . His words are these : Imagine we therefore , that God should please to annihilate the whole stock or mass of Elements , and all concretions resulting therefrom , that is , all corporeal substances now contained within the ambit or concave of the lowest Heaven , or Lunar sphear ; and having thus imagined , can we conceive that all the vast space or region circumscribed by the concave superfice of the Lunar sphere , would not remain the same in all its dimensions , after as before the reduction of all bodies included therein to nothing ? To which , I answer : That , in my opinion , he makes Nature Supernatural ; for although God's Power may make Vacuum , yet Nature cannot ; for God's and Nature's Power are not to be compared , neither is God's invisible Power perceptible by Natures parts ; but according to Natural Perception , it is impossible to conceive a Vacuum , for we cannot immagine a Vacuum , but we must think of a body , as your Author of the Circle of the Moon ; neither could he think of space but from one side of the Circle to the other , so that in his mind he brings two sides together , and yet will have them distant ; but the motions of his thoughts being subtiler and swifter then his senses , skip from side to side without touching the middle parts , like as a Squirrel from bough to bough , or an Ape from one table to another , without touching the ground , onely cutting the air . Next , he says , That an absolute Vacuum , is neither an Accident , nor a Body , nor yet Nothing , but Something , because it has a being ; which opinion seems to me like that of the divine Soul ; but I suppose Vacuum is not the divine Soul , nor the divine Soul , Vacuum ; or else it could not be sensible of the blessed happiness in Heaven , or the Torments in Hell . Again he says , Let us screw our supposition one pin higher , and farther imagine , that God , after the annihilation of this vast machine , the Universe , should create another in all respects equal to this , and in the same part of space wherein this now consists : First , we must conceive , that as the spaces were immense before God created the world , so also must they eternally persist of infinite extent , if he shall please at any time to destroy it ; Next , that these immense spaces are absolutely immoveable . By this opinion , it seems , that Gods Power cannot so easily make or annihilate Vacuum , as a substance ; because he believes it to be before all Matter , and to remain after all Matter , which is to be eternal ; but I cannot conceive , why Matter , or fulness of body , should not as well be Infinite and Eternal , as his conceived Vacuum ; for if Vacuum can have an eternal and infinite being , why may not fulness of body , or Matter ? But he calls Vacuum Immovable , which in my opinion is to make it a God ; for God is onely Immoveable and Unalterable , and this is more Glorious then to be dependant upon God ; wherefore to believe Matter to be Eternal , but yet dependent upon God , is a more humble opinion , then his opinion of Vacuum ; for if Vacuum be not created , and shall not be annihilated , but is Uncreated , Immaterial , Immoveable , Infinite , and Eternal , it is a God ; but if it be created , God being not a Creator of Nothing , nor an annihilator of Nothing , but of Something , he cannot be a Creator of Vacuum ; for Vacuum is a pure Nothing . But leaving Nothing to those that can make something of it , I will add no more , but rest ,

THat Learned Author , of whom I made mention in my last , is pleased to say in his Chapter of Time , that Time is the Twin-brother to Space ; but if Space be as much as Vacuum , then I say , they are Twin-nothings ; for there can be no such thing as an empty or immaterial space , but that which man calls space , is onely a distance betwixt several corporeal parts , and time is onely the variation of corporeal motions ; for were there no body , there could not be any space , and were there no corporeal motion , there could not be any time . As for Time , considered in General , it is nothing else but the corporeal motions in Nature , and Particular times are the Particular corporeal motions ; but Duration is onely a continuance , or continued subsistence of the same parts , caused by the consistent motions of those parts ; Neither are Time , Duration , Place , Space , Magnitude , &c. dependents upon corporeal motions , but they are all one and the same thing ; Neither was Time before , nor can be after corporeal motion , for none can be without the other , being all one : And as for Eternity , it is one fixed instant , without a flux , or motion . Concerning his argument of Divisibility of Parts , my opinion is , That there is no Part in Nature Individable , no not that so small a part , which the Epicureans name an Atome ; neither is Matter separable from Matter , nor Parts from Parts in General , but onely in Particulars ; for though parts can be separated from parts , by self-motion , yet upon necessity they must joyn to parts , so as there can never be a single part by it self . But hereof , as also of Place , Space , Time , Motion , Figure , Magnitude , &c. I have sufficiently discoursed in my former Letters , as also in my Book of Philosophy ; and as for my opinion of Atoms , their figures and motions , ( if any such things there be ) I will refer you to my Book of Poems , out of which give me leave to repeat these following lines , containing the ground of my opinion of Atomes :

All Creatures , howsoe're they may be nam'd , Pag. 7. in the second Impression . Are of long , square , flat , or sharp Atomes fram'd . Thus several figures several tempers make , Pag. 9. But what is mixt , doth of the four partake . The onely cause , why things do live and die , Pag. 22. 'S according as the mixed Atomes lie . Thus life , and death , and young , and old , Pag. 24. Are as the several Atoms hold : Wit , understanding in the brain Are as the several atomes reign : And dispositions , good , or ill , Are as the several atomes still ; And every Passion , which doth rise , Is as each several atome lies . Thus sickness , health , and peace , and war , Are as the several atomes are .

If you desire to know more , you may read my mentioned Book of Poems whose first Edition was printed in the year , 1653. And so taking my leave of you , I rest ,

X. MADAM ,

I Received the Book of your new Author that treats of Natural Philosophy , which I perceive is but lately come forth ; but although it be new , yet there are no new opinions in it ; for the Author doth follow the opinions of some old Philosophers , and argues after the accustomed Scholastical way , with hard , intricate , and nonsensical words : Wherefore I shall not take so much pains as to read it quite over , but onely pick out here and there some few discourses , which I shall think most convenient for the clearing of my own opinion ; in the number of which , is , first , that of Matter , whereof the Author is pleased to proclaim the opinion that holds Matter to be Infinite , not onely absurd , but also impious . Truly , Madam , it is easily said , but hardly proved ; and not to trouble you with unnecessary repetitions , I hope you do remember as yet what I have written to you in the beginning concerning the infiniteness of Nature , or natural Matter , where I have proved that it implies no impiety , absurdity , or contradiction at all , to believe that Matter is Infinite ; for your Authors argument , concluding from the finiteness of particular Creatures to Nature her self , is of no force ; for though no part of Nature is Infinite in bulk , figure , or quantity , nevertheless , all the parts of Infinite Nature are Infinite in number , which infinite number of parts must needs make up one Infinite body in bulk , or quantity ; for as a finite body or substance is dividable into finite parts , so an Infinite body , as Nature , or natural Matter , must of necessity be dividable into infinite parts in number , and yet each part must also be finite in its exterior figure , as I have proved in the beginning by the example of a heap of grains of corn . Certainly , Madam , I see no reason , but since , according to your Author , God , as the prime Cause , Agent , and Producer of all things , and the action by which he produced all things , is Infinite ; the Matter out of which he produced all particular Creatures may be Infinite also . Neither doth it , to my sense and reason , imply any contradiction or impiety ; for it derogates nothing from the Glory and Omnipotency of God , but God is still the God of Nature , and Nature is his Servant , although Infinite , depending wholly upon the will and pleasure of the All-powerful God : Neither do these two Infinites obstruct each other ; for Nature is corporeal , and God is a supernatural and spiritual Infinite Being , and although Nature has an Infinite power , yet she has but an Infinite Natural power , whereas Gods Omnipotency is infinitely extended beyond Nature . But your Author is pleased to refute that argument , which concludes from the effect to the cause , and proves Matter to be infinite , because God as the Cause is Infinite , saying , that this Rule doth onely hold in Univocal things , ( by which , I suppose , he understands things of the same kind and nature ) and not in opposites . Truly , Madam , by this he limits Gods power , as if God were not able to work beyond Nature , and Natural Reason or Understanding ; and measures Gods actions according to the rules of Logick ; which whether it be not more impious , you may judg your self . And as for opposites , God and Nature are not opposites , except you will call opposites those which bear a certain relation to one another , as a Cause , and its Effect ; a Parent , and a Child ; a Master , and a Servant ; and the like . Nay , I wonder how your Author can limit Gods action , when as he confesses himself , that the Creation of the World is an Infinite action . God acted finitely , says he , by an Infinite action ; which , in my opinion , is meer non-sense , and as much as to say , a man can act weakly by a strong action , basely by an honest action , cowardly by a stout action . The truth is , God being Infinite , cannot work finitely ; for , as his Essence , so his Actions cannot have any limitation , and therefore it is most probable , that God made Nature Infinite ; for though each part of Nature is finite in its own figure , yet considered in general , they are Infinite , as well in number , as duration , except God be pleased to destroy them ; nay , every particular may in a certain sense be said Infinite , to wit , Infinite in time or duration ; for if Nature be Infinite and Eternal , and there be no annihilation or perishing in Nature , but a perpetual successive change and alteration of natural figures , then no part of Nature can perish or be annihilated ; and if no part of Nature perishes , then it lasts infinitely in Nature , that is , in the substance of natural Matter ; for though the corporeal motions , which make the figures , do change , yet the ground of the figure , which is natural matter , never changes . The same may be said of corporeal motions : for though motions change and vary infinite ways , yet none is lost in Nature , but some motions are repeated again : As for example ; the natural motions in an Animal Creature , although they are altered in the dissolution of the animal figure , yet they may be repeated again by piece-meals in other Creatures ; like as a Commonwealth , or united body in society , if it should be dissolved and dispersed , the particulars which did constitute this Commonwealth or society , may joyn to the making of another society ; and thus the natural motions of a body do not perish when the figure of the body dissolves , but joyn with other motions to the forming and producing of some other figures . But to return to your Author . I perceive his discourse is grounded upon a false supposition , which appears by his way of arguing from the course of the Starrs and Planets , to prove the finiteness of Nature ; for by reason the Stars and Planets rowl about , and turn to the same point again , each within a certain compass of time , he concludes Nature or Natural Matter to be finite too . And so he takes a part for the whole , to wit , this visible World for all Nature , when as this World is onely a part of Nature , or Natural Matter , and there may be more and Infinite worlds besides ; Wherefore his conclusion must needs be false , since it is built upon a false ground . Moreover , he is as much against the Eternity of Matter , as he is against Infiniteness ; concluding likewise from the parts to the whole : For , says he , since the parts of Nature are subject to a beginning and ending , the whole must be so too . But he is much mistaken , when he attributes a beginning and ending to parts , for there is no such thing as a beginning and ending in Nature , neither in the whole , nor in the parts , by reason there is no new creation or production of Creatures out of new Matter , nor any total destruction or annihilation of any part in Nature , but onely a change , alteration and transmigration of one figure into another ; which change and alteration proves rather the contrary , to wit , that Matter is Eternal and Incorruptible ; for if particular figures change , they must of necessity change in the Infinite Matter , which it self , and in its nature , is not subject to any change or alteration : besides , though particulars have a finite and limited figure , and do change , yet their species do not ; for Mankind never changes , nor ceases to be , though Peter and Paul die , or rather their figures dissolve and divide ; for to die is nothing else , but that the parts of that figure divide and unite into some other figures by the change of motion in those parts . Concerning the Inanimate Matter , which of it self is a dead , dull , and idle matter , your Author denies it to be a co-agent or assistant to the animate matter : For , says he , how can dead and idle things act ? To which , I answer : That your Author being , or pretending to be a Philosopher , should consider that there is difference betwixt a Principal and Instrumental cause or agent ; and although this inanimate , or dull matter , doth not act of it self as a principal agent , yet it can and doth act as an Instrument , according as it is imploy'd by the animate matter : for by reason there is so close a conjunction and commixture of animate and inanimate Matter in Nature , as they do make but one body , it is impossible that the animate part of matter should move without the inanimate ; not that the inanimate hath motion in her self , but the animate bears up the inanimate in the action of her own substance , and makes the inanimate work , act , and move with her , by reason of the aforesaid union and commixture . Lastly , your Author speaks much of Minima's , viz. That all things may be resolved into their minima's , and what is beyond them , is nothing , and that there is one maximum , or biggest , which is the world , and what is beyond that , is Infinite . Truly , Madam , I must ingeniously confess , I am not so high learned , as to penetrate into the true sense of these words ; for he says , they are both divisible , and indivisible , and yet no atomes , which surpasses my Understanding ; for there is no such thing , as biggest and smallest in Nature , or in the Infinite matter ; for who can know how far this World goes , or what is beyond it ? There may be Infinite Worlds , as I said before , for ought we know ; for God and Nature cannot be comprehended , ' nor their works measured , if we cannot find out the nature of particular things , which are subject to our exterior senses , how shall we be able to judg of things not subject to our senses . But your Author doth speak so presumptuously of Gods Actions , Designs , Decrees , Laws , Attributes , Power , and secret Counsels , and describes the manner , how God created all things , and the mixture of the Elements to an hair , as if he had been Gods Counsellor and Assistant in the work of Creation ; which whether it be not more impiety , then to say , Matter is Infinite , I 'le let others judg . Neither do I think this expression to be against the holy Scripture ; for though I speak as a natural Philosopher , and am unwilling to cite the Scripture , which onely treats of things belonging to Faith and , and not to Reason ; yet I think there is not any passage which plainly denies Matter to be Infinite , and Eternal , unless it be drawn by force to that sense : Solomon says , That there is not any thing new : and in another place it is said , That God is all fulfilling ; that is , The Will of God is the fulfilling of the actions of Nature : also the Scripture says , That Gods ways are unsearchable , and past finding out . Wherefore , it is easier to treat of Nature , then the God of Nature ; neither should God be treated of by vain Philosophers , but by holy Divines , which are to deliver and interpret the Word of God without sophistry , and to inform us as much of Gods Works , as he hath been pleased to declare and make known . And this is the safest way , in the opinion of ,

YOur new Author endeavours to prove , that Water in its own proper nature is thicker then Earth ; which , to my sense and reason , seems not probable ; for although water is less porous then earth in its exterior figure , yet 't is not so thick as earth in its interior nature : Neither can I conceive it to be true , that water in its own nature , and as long as it remains water , should be as hard as Crystal , or stone , as his opinion is ; for though Elements are so pliant ( being not composed of many different parts and figures ) as they can change and rechange their exterior figures , yet they do not alter their interior nature without a total dissolution ; but your Author may as well say , that the interior nature of man is dust and ashes , as that water in its interior nature is as thick as earth , and as hard as Christal , or stone ; whereas yet a man , when he becomes dust and ashes , is not a man ; and therefore , when water is become so thick as earth , or so hard as stone , it is not water ; I mean when it is so in its interior nature , not in its exterior figure ; for the exterior figure may be contracted , when yet the interior nature is dilative ; and so the exterior may be thick or hard , when the interior is soft and rare . But you may say , that water is a close , and heavy , as also a smooth and glossy body . I answer : That doth not prove its interior nature to be hard , dense , thick , or contracted ; for the interior nature and parts of a body may be different from the exterior figure or parts ; neither doth the close joyning of parts hinder dilatation ; for if so , a line or circle could not dilate or extend : But this close uniting of the parts of water is caused through its wet and glutinous quality , which wet and sticking quality is caused by a watery dilatation ; for though water hath not interiously so rare a dilatation as Air , Fire , and Light , yet it hath not so close a contraction as Earth , Stone , or Metal ; neither are all bodies that are smooth and shining , more solid and dense , then those that are rough and dark ; for light is more smooth , glossy , and shining , then Water , Metal , Earth , or Transparent-stones , and yet is of a dilative nature . But because some bodies and figures which are transparent and smooth , are dense , hard , and thick , we cannot in reason , or sense , say , that all bodies and figures are so . As for Transparency , it is caused through a purity of substance , and an evenness of parts : the like is glossiness , onely glossiness requires not so much regularity , as transparency . But to return to Water ; its exterior Circle-figure may easily dilate beyond the degree of the propriety or nature of water , or contract beneath the propriety or nature of water . Your Author may say , Water is a globous body , and all globous bodies tend to a Center . I answer : That my sense and reason cannot perceive , but that Circles and Globes do as easily dilate , as contract : for if all Globes and Circles should endeavour to draw or fall from the circumference to the Center , the Center of the whole World , or at least of some parts of the World , would be as a Chaos : besides , it is against sense and reason , that all Matter should strive to a Center ; for humane sense and reason may observe , that all Creatures , and so Matter , desire liberty , and a Center is but a Prison in comparison to the Circumference ; wherefore if Matter crowds , it is rather by force , then a voluntary action . You will say , All Creatures desire rest , and in a Center there 's rest . I answer ; Humane sense and reason cannot perccive any rest in Nature : for all things , as I have proved heretofore , are in a perpetual motion . But concerning Water , you may ask me , Madam , Whether congeal'd Water , as Ice , if it never thaw , remains Water ? To which , I answer : That the interior nature of Water remains as long as the Ice remains , although the outward form is changed ; but if Ice be contracted into the firmness and density of Crystal , or Diamond , or the like , so as to be beyond the nature of Water , and not capable to be that Water again , then it is transformed into another Creature , or thing , which is neither Water , nor Ice , but a Stone ; for the Icy contraction doth no more alter the interior nature of Water , which is dilating , then the binding of a man with Chains alters his nature from being a man ; and it might be said as well , that the nature of Air is not dilating , when inclosed in a bladder , as that Water doth not remain Water in its interior nature , when it is contracted into Ice . But you may ask , Whether one extreme can change into another ? I answer : To my sense and reason it were possible , if extremes were in Nature ; but I do not perceive that in Nature there be any , although my sense and reason doth perceive alterations in the effects of Nature ; for though one and the same part may alter from contraction to dilation , and from dilation to contraction ; yet this contraction and dilation are not extremes , neither are they performed at one and the same time , but at different times . But having sufficiently declared my opinion hereof in my former Letters , I 'l add no more , but rest ,

MY discourse of Water in my last Letter has given you occasion to enquire after the reason , Why the weight of a great body of water doth not press so hard and heavily as to bruise or crush a body , when it is sunk down to the bottom ? As for example : If a man should be drowned , and afterwards cast out from the bottom of a great Sea , or River , upon the shore ; he would onely be found smother'd or choak'd to death , and not press'd , crush'd , or bruised , by the weight of water . I answer ; The reasons are plain : for , first , the nature of a mans respiration requires such a temperature of breath to suck in , as is neither too thick , nor too thin for his lungs , and the rest of his interior parts , as also for the organs and passages of his exterior senses , but fit , proper , and proportionable to those mentioned parts of his body : As for example ; in a too thin and rarified air , man will be as apt to die for want of breath , as in a too gross and thick air he is apt to die with a superfluity of the substance he imbreaths ; for thick smoak , or thick vapour , as also too gross air , will soon smother a man to death ; and as for choaking , if a man takes more into his throat then he can swallow , he will die ; and if his stomack be filled with more food then it is able to digest , if it cannot discharge it self , he will die with the excess of food ; and if there be no food , or too little put into it , he will also die for want of food . So the eye , if it receives too many , or too gross , or too bright objects , it will be dazled or blinded , and some objects through their purity are not to be seen at all : The same for Hearing , and the rest of the exterior senses . And this is the reason , why man , or some animal Creatures are smother'd and choak'd with water ; because water is thicker then the grossest air or vapour ; for if smoak , which is rarer then water , will smother and choak a man , well may water , being so much thicker . But yet this smothering or choaking doth not prove , that water hath an interior or innate density ( as your Authors opinion is ) no more then smoak , or thick and gross air hath ; but the density of water is caused more through the wet and moist exterior parts , joyning and uniting closely together ; and the interior nature of smoak being more moist or glutinous then thin air , and so more apt to unite its exterior parts , it makes it to come in effect nearer to water ; for though water and smoak are both of rare natures , yet not so rare as clear and pure air ; neither is water or smoak so porous as pure air , by reason the exterior parts of water and smoak are more moist or glutinous then pure air . But the thickness of water and smoak is the onely cause of the smothering of men , or some animals , as by stopping their breath ; for a man can no more live without air , then he can without food ; and a well tempered or middle degree of air is the most proper for animal Respiration ; for if the air be too thick , it may soon smother or choak him ; and if too thin , it is not sufficient to give him breath : And this is the reason that a man being drown'd , is not onely smother'd , but choak'd by water ; because there enters more through the exterior passages into his body then can be digested ; for water is apt to flow more forcibly and with greater strength then air ; not that it is more dilating then air , but by reason it is thicker , and so stronger , or of more force ; for the denser a body is , the stronger it is ; and a heavy body , when moved , is more forcible then a light body . But I pray by this expression mistake not the nature of water ; for the interior nature of water hath not that gravity , which heavy or dense bodies have , its nature being rare and light , as air , or fire ; but the weight of water , as I said before , proceeds onely from the closeness and compactness of its exterior parts , not through a contraction in its interior nature ; and there is no argument , which proves better , that water in its interior nature is dilating , then that its weight is not apt to press to a point ; for though water is apt to descend , through the union of its parts , yet it cannot press hard , by reason of its dilating nature , which hinders that heavy pressing quality ; for a dilating body cannot have a contracted weight , I mean , so as to press to a Center , which is to a point ; and this is the reason , that when a grave or heavy body sinks down to the bottom of water , it is not opprest , hurt , crusht , or bruised by the weight of water ; for , as I said , the nature of water being dilating , it can no more press hard to a center , then vapour , air , or fire : The truth is , water would be as apt to ascend as descend , if it were not for the wet , glutinous and sticking , cleaving quality of its exterior parts ; but as the quantity and quality of the exterior parts makes water apt to sink , or descend , so the dilating nature makes it apt to flow , if no hinderance stop its course ; also the quantity and quality of its exterior parts is the cause , that some heavy bodies do swim without sinking : as for example ; a great heavy Ship will not readily sink , unless its weight be so contracted as to break asunder the united parts of water ; for the wet quality of water causing its exterior parts to joyn close , gives it such an united strength , as to be able to bear a heavy burden , if the weight be dilated , or level , and not piercing or penetrating ; for those bodies that are most compact , will sink sooner , although of less weight then those that are more dilated although of greater weight : Also the exterior and outward shape or form makes some bodies more apt to sink then others ; Indeed , the outward form and shape of Creatures is one of the chief causes of either sinking or swimming . But to conclude , water in its interior nature is of a mean or middle degree , as neither too rare , nor too grave a body ; and for its exterior quality , it is in as high a degree for wetness , as fire is for heat ; and being apt both to divide , and to unite , it can bear a burden , and devour a burden , so that some bodies may swim , and others sink ; and the cause , that a sunk body is not opprest , crush'd , or squeesed , is the dilating nature and quality of water , which hinders its parts from pressing or crowding towards a point or center ; for although water is heavy , and apt to descend , yet its weight is not caused by a contraction of its substance , but by a union of its parts . Thus , Madam , I have obeyed your commands , in giving you my reasons to your propounded question ; which if you approve , I have my aim ; if not , I submit to your better judgment : for you know I am in all respects ,

MADAM , Your Faithful Friend to serve you .
XIII . MADAM ,

I Am glad , you are pleased with my reasons I gave to your propounded question concerning the weight of Water ; and since you have been pleased to send me some more of that subject , I shall be ready also to give my answer to them , according to the capacity of my judgment . First , you desire to know , How it comes , that Water will by degrees ascend through a narrow pipe , when the pipe is placed straight upright , or perpendicular ? The reason , in my opinion is , that Water , having a dilative nature , when it finds an obstruction to descend or flow even , will dilate it self ascendingly , according as it hath liberty , or freedom , and strength , or quantity ; the truth is , water would be more apt to ascend then to descend , were it not for the close uniting of its liquid Parts , which causes its exterior density , and this density makes it of more weight then its nature is ; and the proof that water is apt in its nature to ascend , is , that some sorts of vapours are made onely by the dilation and rarefaction of ascending Water . Your second question is , Why the surface of water seems to be concave in its middle , and higher on every side ? I answer , The interior figure of water is a circular figure , which being a round figure , is both concave , and convex ; for where one is , the other must be ; and the motions of ebbing and flowing , and ascending or descending , are partly of that figure ; and so according to the exterior dilating strength or weakness , the exterior parts of water become either concave or convex ; for in a full strength , as a full stream , the exterior parts of water flow in a convex figure , but when they want strength , they ebb in a concave figure . Your third question is , What makes frozen water apt to break those Vessels wherein it is contained , in the act of freezing or congealing ? I answer : The same cause that makes water clear , as also more swell'd then usually it is : which cause is the inherent dilative nature of water ; for water being naturally dilative , when as cold attractions do assault it , the moist dilations of water in the conflict use more then their ordinary strength to resist those cold contracting motions , by which the body of water dilates it self into a larger compass , according as it hath liberty or freedom , or quantity of parts ; and the cold parts not being able to drive the water back to its natural compass , bind it as it is extended , like as if a beast should be bound when his legs and neck are thrust out at the largest extent , in striving to kick or thrust away his enemies and imprisoners : And so the reason why water breaks those vessels wherein it is inclosed , in the act of its freezing or congealing is , that when the cold contractions are so strong as they endeavour to extinguish the dilating nature of water , the water resisting , forces its parts so , as they break the vessel which incloses them : The same reason makes Ice clear and transparent ; for it is not the rarefaction of water that doth it , but the dilation , which causes the parts of water to be not onely more loose and porous , but also more smooth and even , by resisting the clold contractions ; for every part endeavours to defend their borders with a well ordered and regular flowing or streaming , and not onely to defend , but to enlarge their compass against their enemies . Your fourth question is , How it comes that Snow and Salt mixt together doth make Ice ? The reason , in my judgment , is , that Salt being very active , and partly of the nature of fire , doth sometimes preserve , and sometimes destroy other bodies , according to its power , or rather according to the nature of those bodies it works on ; and salt being mixt with snow , endeavours to destroy it ; but having not so much force , melts it onely by its heat , and reduces it into its first principle , which is water , altering the figure of snow ; but the cold contractions remaining in the water , and endeavouring to maintain and keep their power , straight draw the water or melted snow into the figure of ice , so as neither the salts heat , nor the waters dilative nature , are able to resist or destroy those cold contractions ; for although they destroy'd the first figure , which is snow , yet they cannot hinder the second , which is Ice , Your last question is , How the Clouds can hang so long in the Skie without falling down ? Truly , Madam , I do not perceive that Clouds , being come to their full weight and gravity , do keep up in the air , but some of them fall down in showres of rain , others in great and numerous flakes of snow ; some are turned into wind , and some fall down in thick mists , so that they onely keep up so long , until they are of a full weight for descent , or till their figure is altered into some other body , as into air , wind , rain , lightning , thunder , snow , hail , mist , and the like . But many times their dilating motions keep or hinder them from descending , to which contracting motions are required . In my opinion , it is more to be admired , that the Sea doth not rise , then that Clouds do not fall ; for , as we see , Clouds fall very often , as also change from being Clouds , to some other figure : Wherefore it is neither the Sun , nor Stars , nor the Vapours , which arise from the Earth , and cause the Clouds , nor the porositity of their bodies , nor the Air , that can keep or hinder them from falling or changing to some other body ; but they being come to their full weight , fall or change according as is fittest for them . And these are all the reasons I can give you for the present ; if they do not satisfie you , I will study for others , and in all occasions endeavour to express my self ,

SInce in my last , I made mention of the Congealing of Water into Ice and Snow , I cannot choose , but by the way tell you , that I did lately meet with an Author , who is of opinion , That Snow is nothing else but Ice broken or ground into small pieces . To which , I answer : That this opinion may serve very well for a Fancy , but not for a Rational Truth , or at least for a Probable Reason ; For why may not the cold motions make snow without beating or grinding , as well as they make Ice ? Surely Nature is wiser then to trouble her self with unnecessary labour , and to make an easie work difficult , as Art her Creature doth , or as some dull humane capacities conceive ; for it is more easie for Nature to make Snow by some sorts of cold contractions , as she makes Ice by other sorts of cold contractions , then to force Air and Wind to beat , grinde , or pound Ice into Snow , which would cause a confusion and disturbance through the Irregularity of several parts , being jumbled in a confused manner together . The truth is , it would rather cause a War in Nature , then a natural production , alteration , or transformation : Neither can I conceive , in what region this turbulent and laborious work should be acted ; certainly not in the caverns of the Earth , for snow descends from the upper Region . But , perchance , this Author believes , that Nature imploys Wind as a Hand , and the Cold air as a Spoon , to beat Ice like the white of an Egg into a froth of Snow . But the great quantity of Snow , in many places , doth prove , that Snow is not made of the fragments of Ice , but that some sorts of cold contractions on a watery body , make the figure of snow in the substance of water , as other sorts of cold contractions make the figure of ice ; which motions and figures I have treated of in my Book of Philosophy , according to that Judgment and Reason which Nature has bestowed upon me . The Author of this Fancy , gives the same reason for Snow being white : For Ice , says he , is a transparent body , and all transparent bodies , when beaten into powder , appear white ; and since Snow is nothing else but Ice powder d small , it must of necessity shew white . Truly , Madam , I am not so experienced , as to know that all transparent bodies , being beaten small , shew white ; but grant it be so , yet that doth not prove , that the whiteness of snow proceeds from the broken parts of Ice , unless it be proved that the whiteness of all bodies proceeds from the powdering of transparent bodies , which I am sure he cannot do ; for Silver , and millions of other things are white , which were never produced from the powder of transparent bodies : Neither do I know any reason against it , but that which makes a Lilly white , may also be the cause of the whiteness of Snow , that is , such a figure as makes a white colour ; for different figures , in my opinion , are the cause of different colours , as you will find in my Book of Philosophy , where I say , that Nature by contraction of lines draws such or such a Figure , which is such or such a Colour ; as such a Fgure is red , and such a Figure is green , and so of all the rest : But the Palest colours , and so white , are the loosest and slackest figures ; Indeed , white , which is the nearest colour to light , is the smoothest , evenest and straightest figure , and composed of the smallest lines : As for example ; suppose the figure of 8. were the colour of Red , and the figure of 1. the colour of White ; or suppose the figure of Red to be a z. and the figure of an r. to be the figure of Green , and a straight l. the figure of White ; And mixt figures make mixt colours : The like examples may be brought of other Figures , as of a Harpsichord and its strings , a Lute and its strings , a Harp and its strings , &c. By which your Reason shall judg , whether it be not easier for Nature , to make Snow and its whiteness by the way of contraction , then by the way of dissolution : As for example ; Nature in making Snow , contracts or congeals the exterior figure of Water into the figure of a Harp , which is a Triangular figure with the figure of straight strings within it ; for the exterior figure of the Harp represents the exterior figure of Snow , and the figure of the strings extended in straight lines represent the figure of its whiteness . And thus it is easier to make Snow and its whiteness at one act , then first to contract or congeal water into Ice , and then to cause wind and cold air to beat and break that Ice into powder , and lastly to contract or congeal that powder into flakes of Snow ? Which would be a very troublesom work for Nature , viz. to produce one effect by so many violent actions and several labours , when the making of two figures by one action will serve the turn . But Nature is wiser then any of her Creatures can conceive ; for she knows how to make , and how to dissolve , form , and transform , with facility and ease , without any difficulty ; for her actions are all easie and free , yet so subtil , curious and various , as not any part or creature of Nature can exactly or throughly trace her ways , or know her wisdom . And thus leaving her , I rest ,

XV. MADAM ,

I Have taken several questions out of your new Author , which I intend to answer in this present Letter according to the conceptions of my own sense and reason , and to submit them to your censure ; which if you vouchsafe to grant me without partiality , I shall acknowledge my self much obliged to you for this favour . The first question is , Why wet Linnen is dried in the Air ? I answer ; That , according to my sense and reason , the water which is spred upon the linnen , being not united in a full and close body , dilates beyond the Circle-degree of water and wetness , and so doth easily change from water to vapour , and from vapour to air , whereby the linnen becomes as dry , as it was before it became wet . The second question is , Why Water and Wine intermix so easily and suddenly together ? I answer : All wet liquors , although their exterior figures do differ , yet their interior natures , figures and forms are much alike , and those things that are of the same interior nature , do easily and suddenly joyn as into one : Wherefore Wine and Water having both wet natures , do soon incorporate together , whereas , were they of different natures , they would not so peaceably joyn together , but by their contrary natures become enemies , and strive to destroy each other ; but this is to be observed , that the sharp points of the Circle-lines of Wine , by passing through the smooth Circle-lines of Water , help to make a more hasty and sudden conjunction . The third question , is , Why Light , which in its nature is white , shining through a coloured Glass , doth appear of the same colour which the Glass is of , either Blew , Green , Red , or the like ? I answer : The reason is , that though Light in its nature be white , and the Glass clear and transparent , yet when as the Glass is stained or painted with colours , both the clearness of the glass , and the whiteness of the light , is obstructed by the figure of that colour the glass is stained or painted withal , and the light spreading upon or thorow the glass , represents it self in the figure of that same colour ; indeed , in all probability to sense and reason , it appears , that the lines or beams of light , which are straight , small , even , and parallel , do contract in their entrance through the glass into the figure of the colour the glass is stained or painted with , so that the light passes through the glass figuratively , in so much , as it seems to be of the same colour the glass is of , although in it self it is white , lucent , and clear ; and as the light appears , so the eye receives it , if the sight be not destructive . The fourth question , is , Whether ( as your Authors opinion is ) kisses feel pleasing and delightful by the thinness of the parts , and a gentle stirring and quavering of the tangent spirits , that give a pleasing tact ? I answer : If this were so , then all kisses would be pleasing , which surely are not ; for some are thought very displeasing , especially from thin lips ; wherefore , in my opinion , it is neither the thinness of the parts of the lips , nor the quavering of the tangent spirits , but the appetites and passions of life , reason , and soul , that cause the pleasure : Nevertheless , I grant , the stirring up of the spirits may contribute to the increasing , heightning , or strengthning of that tact , but it is not the prime cause of it . The fifth question , is , Whether the greatest man have always the greatest strength ? I answer , Not : for strength and greatness of bulk doth not always consist together , witness experience : for a little man may be , and is oftentimes stronger then a tall man . The like of other animal Creatures : As for example , some Horses of a little or middle size , have a great deal more strength then others which are high and big ; for it is the quantity of sensitive matter that gives strength , and not the bigness or bulk of the body . The sixth question , is , Whether this World or Vniverse be the biggest Creature ? I answer : It is not possible to be known , unless Man could perfectly know its dimension or extension , or whether there be more Worlds then one : But , to speak properly , there is no such thing as biggest or least in Nature . The seventh question , is , Whether the Earth be the Center of Matter , or of the World ? As for Matter , it being Infinite , has no Center , by reason it has no Circumference ; and , as for this World , its Center cannot be known , unless man knew the utmost parts of its circumference , for no Center can be known without its circumference ; and although some do imagine this world so little , that in comparison to Infinite Matter , it would not be so big as the least Pins head , yet their knowledg cannot extend so far as to know the circumference of this little World ; by which you may perceive the Truth of the old saying , Man talks much , but knows little . The eighth question is , Whether all Centers must needs be full , and close , as a stufft Cushion ; and whether the matter in the Center of the Vniverse or World be dense , compact , and heavy ? I answer : This can no more be known , then the circumference of the World ; for what man is able to know , whether the Center of the world be rare , or dense , since he doth not know where its Center is ; and as for other particular Centers , some Centers may be rare , some dense , and some may have less matter then their circumferences . The ninth question is , Whether Finite Creatures can be produced out of an Infinite material cause ? I answer : That , to my sense and reason , an Infinite cause must needs produce Infinite effects , though not in each Particular , yet in General ; that is , Matter being Infinite in substance , must needs be dividable into Infinite parts in number , and thus Infinite Creatures must needs be produced out of Infinite Matter ; but Man being but a finite part , thinks all must be finite too , not onely each particular Creature , but also the Matter out of which all Creatures are produced , which is corporeal Nature . Nevertheless , those Infinite effects in Nature are equalized by her different motions which are her different actions ; for it is not non-sence , but most demonstrable to sense and reason that there are equalities or a union in Infinite . The tenth question is , Whether the Elements be the onely matter out of which all other Creatures are produced ? I answer : The Elements , as well as all other Creatures , as it appears to humane sense and reason , are all of one and the same Matter , which is the onely Infinite Matter ; and therefore the Elements cannot be the Matter of all other Creatures , for several sorts of Creatures have several ways of productions , and I know no reason to the contrary , but that Animals , Vegetables , and Minerals , may as well derive their essence from each other , as from the Elements , or the Elements from them ; for as all Creatures do live by each other , so they are produced from each other , according to the several ways or manners of productions . But mistake me not , Madam , for I speak of production in General , and not of such natural production whereby the several species of Creatures are maintained : As for example , Generation in Animals ; for an Element cannot generate an Animal in that manner as an Animal can generate or produce its like ; for as Nature is wise , so her actions are all wise and orderly , or else it would make a horrid confusion amongst the Infinite parts of Nature . The eleventh question is , What is meant by Natural Theology ? I answer : Natural Theology , in my opinion , is nothing else but Moral Philosophy ; for as for our belief , it is grounded upon the Scripture , and not upon Reason .

These , Madam , are the Questions which I have pickt out of your new Author , together with my answers , of which I desire your impartial Judgment : But I must add onething more before I conclude ; which is , I am much pleased with your Authors opinion , That Sound may be perceived by the Eye , Colour by the Ear , and that Sound and Colour may be smell'd and tasted ; and I have been of this opinion eleven years since , as you will find in my Book of Poems , whose first Edition was printed in the Year , 1653. And thus I take my leave of you , and remain constantly ,

MADAM , Your Faithful Friend to serve you .
XVI . MADAM ,

COncerning your question of the ascending nature of fire , I am absolutely of Aristotle's Opinion , that it is as natural for Fire to ascend , as it is for Earth to descend ; And why should we believe the nature of one , and doubt the nature of the other ? For if it be granted , that there are as well ascending , as descending bodies in Nature , as also low and high places , ( according to the situation of Particulars ) and Circumferences , as well as Centers , ( considering the shape of bodies ) I cannot perceive by humane reason , but that the Nature of fire is ascending , and that it is very improbable , it should have a descending or contracting nature , as to tend or endeavour to a Center . But , Madam , give me leave to ask what sort of Fire you mean , whether a Celestial , or a Terrestrial Fire , viz. that which is named an Elemental fire , or any other sort of fire ? for there may be as many several sorts of fire , as of other Creatures ; or whether you mean onely that sort of fire that belongs to this terrestrial Globe , or all the fire in general that is in Infinite Nature ? and if you mean onely that sort of fire which belongs to this Terrestrial World we live upon ; I answer , There are many several sorts of that fire too ; for all the fire belonging to this Earthly Globe , doth not lie in one place , body , or part , no more then all metal , or but one sort of metal , as Gold , lies in one mine , or all Mankind in one womb . Neither can I believe , that the Sun is the onely Celestial Fire in Nature , but that there may be as numerous Suns , as there are other sorts of Creatures in Nature . But as for the ascending propriety of this terrestrial Fire , you may say , That the Elements do commix and unite in this worldly Globe , and if Fire should have an ascending motion , it would pierce into other Globes , or Worlds , and never leave ascending . I answer : That , first of all , the strength of fire is to be considered , consisting not onely in its quantity , but also in its quality ; as whether it can ascend to those bodies and places which are far above it : For example ; A Man , or any other Creature , hath never so much strength , or ability , or length of life , as to travel to the utmost parts of the Universe , were the way never so plain and free , and the number of men never so great : the like for Elementary fire , which hath life and death , that is , generation and dissolution , and successive motion , as well as other Creatures . But you would fain know , whether fire , if it were left at liberty , would not turn to a Globous figure ? I answer ; That , to my sense and reason , it would not : but some men , seeing the flame of fire in an arched Oven , descend round the sides of the Oven in a Globous figure , do perhaps imagine the nature of fire to be descending , and its natural figure round as a Globe , which is ridiculous ; for the fire in the Oven , although every where incompassed and bound , yet , according to its nature , ascends to the top of the Oven ; and finding a stoppage and suppression , offers to descend perpendicularly ; but by reason of a continual ascending of the following flame , the first , and so all the following parts of flame are forced to spread about , and descend round the sides of the Oven , so that the descension of the flame is forced , and not natural , and its Globous figure is caused , as it were , by a mould , which is the Oven . But some are of opinion , that all bodies have descending motions towards the Center of this worldly Globe , and therefore they do not believe , that any bodies do ascend naturally : But what reason have they to believe one , and not the other ? Besides , how do they know that all bodies would rest in the Center of this terrestriaal Globe , if they came thither ? For if it was possible , that a hole could be digged from the superficies of this Earthly Globe thorow the middle or Center of it unto the opposite superficies , and a stone be sent thorow ; the question is , whether the stone would rest in the Center , and not go quite thorow ? Wherefore this is but an idle Fancy ; and the proof that Fire tends not to a Center , is , because it cannot be poised or weighed , not onely by reason of its rarity , but of its dilative and aspiring Nature ; and as fire is ascending , or aspiring , so likewise do I , Madam , aspire to the top of your favour , and shall never descend from the ambition to serve you , but by the suppression of death . Till then , I remain ,

IN your last , you were pleased to desire my answer to these following Questions : First , What the reason is , that a Vessel , although it be of a solid and compact substance , yet will retain the smell or odour of a forreign substance poured into it , for a long time ? I answer : The Vessel , or rather the perceptive corporeal motions of the Vessel , having patterned out the figure of the sent of the odorous substance , retain that same figure of sent , although the odorous substance is gone ; and as long as that patterned figure is perfect , the sent will remain in the Vessel , either more or less , according as the figure doth last or alter . But you must consider , Madam , that although it be the natural motions that make those patterns of odours , yet those patterned figures are but as it were artificial , like as a man who draws a Copy from an Original ; for Nature has divers and several ways of such motions as we call Art , for whatsoever is an imitation , is that which man calls Art . Your second question was , How it came , that the mind and understanding in many did die or dissolve before the body ? I answer : The reason is , because the rational corporeal motions alter before the sensitive ; for as in some , as for example , in Natural fools , the rational motions never move to a regular humane understanding , so in some dying Persons they do make a general alteration before the sensitive . Your third question was , Why a man , being bitten by a mad Dog , is onely distempered in his mind , and not in his body ? The reason , according to my judgment , is , that the rational part of Matter is onely disturbed , and not the sensitive . The fourth question was , Why a Basilisk will kill with his eyes ? I answer : It is the sensitive corporeal motions in the organ of fight in the man , which upon the printing of the figure of the eyes of the Basilisk , make a sudden alteration . Your fifth question was , Why an Asp will kill insensibly by biting ? The reason , in my opinion , is , That the biting of the Asp hath the same efficacy as deadly Opium hath , yea , and much stronger . Your sixth question was , Why a Dog that rejoyces , swings his tail , and a Lyon when angry , or a Cat when in a fear , do lift up their tails ? I answer : The several motions of the mind may produce either but one , or several sorts of motions in some part or parts of the body ; and as the sensitive motions of anger will produce tears , so will the motions of joy ; but grief made by the rational motions of the mind , may by excess disturb and make a general alteration of the sensitive motions in an animal : the same may excessive joy . But , Madam , you may perhaps find out better reasons for your own questions then these are ; for my endeavour was onely to frame my answer to the ground of my own opinions , and so to satisfie your desire , which was , and is still the ambition of ,

IN your last , you were pleased to desire an account , how far , or how much I did understand the ancient and modern Philosophers in their Philosophical Writings . Truly , Madam , I can more readily tell you what I do not understand , then what I do understand : for , first , I do not understand their sophistical Logick , as to perswade with arguments that black is white , and white is black ; and that fire is not hot , nor water wet , and other such things ; for the glory in Logick is rather to make doubts , then to find truth ; indeed , that Art now is like thick , dark clouds , which darken the light of truth . Next : I do not understand in particular , what they mean by second matter ; for if they name figures and forms second matter , they may as well say , all several motions , which are the several actions of Nature , are several matters , and so there would be infinite several matters , which would produce a meer confusion in Nature . Neither do I understand , when they say , a body dissolves into the first matter ; for I am not able to conceive their first matter , nor what they mean by magna and major materia ; for I believe there is but one matter , and the motion of that matter is its action by which it produces several figures and effects ; so that the nature of the matter is one and the same , although its motions , that is , its actions , be various , for the various effects alter not the nature or unity of the onely matter . Neither do I understand what they mean by corruption , for surely Nature is not corruptible . Nor do I understand their individables in Nature , nor a bodiless form , nor a privation , nor a being without a body ; nor any such thing as they call rest , for there 's not any thing without motion in Nature : Some do talk of moving minima's , but they do not tell what those minima's or their motions are , or how they were produced , or how they came to move . Neither do I understand when they say there is but one World , and that finite ; for if there be no more Matter then that which they call the whole World , and may be measured by a Jacob's staff , then certainly there is but little matter , and that no bigger then an atome in comparison to Infinite . Neither can my reason comprehend , when they say , that not any thing hath power from its interior nature to move exteriously and locally ; for common sense and reason , that is sight and observation , doth prove the contrary . Neither do I know what they mean by making a difference between matter and form , power and act ; for there can be no form without matter , nor no matter without form ; and as act includes power , so power is nothing without act : Neither can I conceive Reason to be separable from matter ; nor what is meant when they say , that , onely that is real , which moves the understanding without . Nor do I understand what they mean by intentionals , accidentals , incorporeal beings , formal ratio , formal unity , and hundreds the like ; enough to puzle truth , when all is but the several actions of one cause , to wit , the onely matter . But most men make such cross , narrow , and intricate ways in Nature , with their over-nice distinctions , that Nature appears like a Labyrinth , whenas really she is as plain as an un-plowed , ditched , or hedged champion : Nay , some make Nature so full , that she can neither move nor stir ; and others again will have her so empty , as they leave not anything within her ; and some with their penetrations , pressings , squeezings , and the like , make such holes in her , as they do almost wound , press and squeeze her to death : And some are so learned , witty , and ingenious , as they understand and know to discourse of the true compass , just weight , exact rules , measures and proportions of the Universe , as also of the exact division of the Chaos , and the architecture of the world , to an atome . Thus , Madam , I have made my confession to you of what I understand not , and have endeavoured to make my ignorance as brief as I could ; but the great God knows , that my ignorance is longer then that which is named life and death ; and as for my understanding , I can onely say , that I understand nothing better , but my self to be ,

SInce I have given you , in my last , an account how much I did understand the Philosophical works of both the ancient and modern Philosophers , or rather what I did not understand of them , you would fain have my op●●●on now of the persons themselves . Truly , Madam , as for those that are dead , or those that are living , I cannot say any thing , but that I believe they all were or are worthy persons , men of vast understandings , subtil conceptions , ingenious wits , painful students , and learned writers . But as for their works , as I told you heretofore , I confess ingeniously , I understand them not , by reason I am ignorant in their Scholastical Arts , as Logick , Metaphysick , Mathematicks , and the like : For to my simple apprehension , when as Logicians argue of natural causes and effects , they make natural causes to produce natural effects with more difficulty and enforcement then Nature knows of ; and as for Mathematicians , they endeavour to inchant Nature with Circles , and bind her with lines so hard , as if she were so mad , that she would do some mischief , when left at liberty . Geometricians weigh Nature to an Atome , and measure her so exactly , as less then a hairs breadth ; besides , they do press and squeeze her so hard and close , as they almost stifle her . And Natural Philosophers do so stuff her with dull , dead , senceless minima's , like as a sack with meal , or sand , by which they raise such a dust as quite blinds Nature and natural reason . But Chymists torture Nature worst of all ; for they extract and distil her beyond substance , nay , into no substance , if they could . As for natural Theologers , I understand them least of any ; for they make such a gallamalfry of Philosophy and Divinity , as neither can be distinguished from the other . In short , Madam , They all with their intricate definitions and distinctions set my brain on the rack : but some Philosophers are like some Poets , for they endeavour to write strong lines . You may ask me , what is meant by strong lines ? I answer : Weak sense . To which leaving them , I rest ,

I Am not of your opinion , That nice distinctions and Logistical arguments discover truth , dissolve doubts , and clear the understanding ; but I say , they rather make doubts of truth , and blind-fold the understanding ; Indeed , nice distinctions and sophistical arguments , are very pernicious both in Schools , Church , and State : As for the Church , although in Divinity there is but one Truth , yet nice distinctions , and Logistical sophistry , have made such confufion in it , as has caused almost as many several opinions as there are words in the Scripture ; and as for natural Theology , which is moral Philosophy , they have divided vertues and vices into so many parts , and minced them so small , that neither can be clearly distinguished . The same in Government ; they endeavour to cut between command and obedience to a hairs breadth . Concerning causes of Law , they have abolish'd the intended benefit , and banish'd equity ; and instead of keeping Peace , they make War , causing enmity betwixt men : As for Natural Philosophy , they will not suffer sense and reason to appear in that study : And as for Physick , they have kill'd more men then Wars , Plagues , or Famine . Wherefore from nice distinctions and Logistical sophistry , Good God deliver us , especially , from those that concern Divinity ; for they weaken Faith , trouble Conscience , and bring in Atheism : In short , they make controversies , and endless disputes . But least the opening of my meaning in such plain terms should raise a controversie also between you and me , I 'le cut off here , and rest ,

YEsterday I received a visit from the Lady N. M. who you know hath a quick wit , rational opinions , and subtil conceptions ; all which she is ready and free to divulge in her discourse . But when she came to my Chamber , I was casting up some small accounts ; which when she did see , What , said she , are you at Numeration ? Yes , said I : but I cannot number well , nor much , for I do not understand Arithrnetick . Said she , You can number to three . Yes , said I , I can number to four : Nay , faith , said she , the number of three is enough , if you could but understand that number well , for it is a mystical number . Said I , There is no great mystery to count that number ; for one , and two , makes three . Said she , That is not the mystery ; for the mystery is , That three makes one : and without this mystery no man can understand Dlvinity , Nature , nor himself . Then I desired her to make me understand that mystery . She said , It required more time to inform me , then a short visit , for this mystery was such , as did puzle all wise men in the world ; aud the not understanding of this mystery perfectly , had caused endless divisions and disputes . I desired , if she could not make me understand the mystery , she would but inform me , how three made one in Divinity , Nature , and Man . She said , That was easie to do ; for in Divinity there are three Persons in one Essence , as God the Father , the Son , and the holy Ghost , whose Essence being individable , they make but one God ; And as for Philosophy , there is but Matter , Motion , and Figure , which being individable , make but one Nature ; And as for Man , there is Soul , Life , and Body , all three joyned in one Man . But I replied , Man's Life , Soul and Body , is dividable . That is true , said she , but then he is no more a Man ; for these three are his essential parts , which make him to be a man ; and when these parts are dissolved , then his interior nature is changed , so that he can no longer be call'd a man : As for example ; Water being turned into Air , and having lost its interior nature , can no more be called Water , but it is perfect Air ; the same is with Man : But as long as he is a Man , then these three forementioned parts which make him to be of that figure are individably united as long as man lasts . Besides , said she , this is but in the particular , considering man single , and by himself ; but in general , these three , as life , soul , and body , are individably united , so that they remain as long as mankind lasts . Nay , although they do dissolve in the particulars , yet it is but for a time ; for they shall be united again at the last day , which is the time of their resurrection ; so that also in this respect we may justly call them individable , for man shall remain with an united soul , life , and body , eternally . And as she was thus discoursing , in came a Sophisterian , whom when she spied , away she went as fast as she could ; but I followed her close , and got hold of her , then asked her , why she ran away ? She answer'd , if she stayed , the Logician would dissolve her into nothing , for the profession of Logicians is to make something nothing , and nothing something . I pray'd her to stay and discourse with the Logician : Not for a world , said she , for his discourse will make my brain like a confused Chaos , full of senseless minima's ; and after that , he will so knock , jolt , and jog it , and make such whirls and pits , as will so torture my brain , that I shall wish I had not any : Wherefore , said she , I will not stay now , but visit you again to morrow . And I wish with all my heart , Madam , you were so near as to be here at the same time , that we three might make a Triumvirate in discourse , as well as we do in friendship . But since that cannot be , I must rest satisfied that I am ,

YOu were pleased to desire my opinion of the works of that Learned and Ingenious Writer B. Truly , Madam , I have read but some part of his works ; but as much as I have read , I have observed , he is a very civil , eloquent , and rational Writer ; the truth is , his style is a Gentleman's style . And in particular , concerning his experiments , I must needs say this , that , in my judgment , he hath expressed himself to be a very industrious and ingenious person ; for he doth neither puzle Nature , nor darken truth with hard words and compounded languages , or nice distinctions ; besides , his experiments are proved by his own action . But give me leave to tell you , that I observe , he studies the different parts and alterations , more then the motions , which cause the alterations in those parts ; whereas , did he study and observe the several and different motions in those parts , how they change in one and the same part , and how the different alterations in bodies are caused by the different motions of their parts , he might arrive to a vast knowledg by the means of his experiments ; for certainly experiments are very beneficial to man . In the next place , you desire my opinion of the Book call'd , The Discourses of the Virtuosi in France : I am sorry , Madam , this book comes so late to my hands , that I cannot read it so slowly and observingly , as to give you a clear judgment of their opinions or discourses in particular ; however , in general , and for what I have read in it , I may say , it expresses the French to be very learned and eloquent Writers , wherein I thought our English had exceeded them , and that they did onely excel in wit and ingenuity ; but I perceive most Nations have of all sorts . The truth is , ingenious and subtil wit brings news ; but learning and experience brings proofs , at least , argumental discourses ; and the French are much to be commended , that they endeavour to spend their time wisely , honourably , honestly , and profitably , not onely for the good and benefit of their own , but also of other Nations . But before I conclude , give me leave to tell you , that concerning the curious and profitable Arts mentioned in their discourses , I confess , I do much admire them , and partly believe they may arrive to the use of many of them ; but there are two arts which I wish with all my heart I could obtain : the first is , to argue without error in all kinds , modes , and figures , in a quarter of an hour ; and the other is to learn a way to understand all languages in six hours . But as for the first , I fear , if I want a thorow-understanding in every particular argument , cause , or point , a general art or mode of words will not help me , especially , if I , being a woman , should want discretion : And as for the second , my memory is so bad , that it is beyond the help of Art , so that Nature has made my understanding harder or closer then Glass , through which the Sun of verity cannot pass , although its light doth ; and therefore I am confident I shall not be made , or taught to learn this mentioned Art in six hours , no not in six months . But I wish all Arts were as easily practised , as mentioned ; and thus I rest ,

COncerning your Question , Whether a Point be something , or nothing , or between both ; My opinion is , that a natural point is material ; but that which the learned name a Mathematical point , is like their Logistical Egg , whereof there is nothing in Nature any otherwise , but a word , which word is material , as being natural ; for concerning immaterial beings , it is impossible to believe there be any in Nature ; and though witty Students , and subtil Arguers have both in past , and this present age , endeavoured to prove something , nothing ; yet words and disputes have not power to annihilate any thing that is in Nature , no more then to create something out of nothing ; and therefore they can neither make something , nothing ; nor nothing to be something : for the most witty student , nor the subtilest disputant , cannot alter Nature , but each thing is and must be as Nature made it . As for your other question , Whether there be more then five Senses ? I answer : There are as many senses as there are sensitive motions ; and all sensation or perception is by the way of patterning ; and whosoever is of another opinion , is , in my judgment , a greater friend to contradiction , then to truth , at least to probability . Lastly , concerning your question , why a Gun , the longer its barrel is made , the further it will shoot , until it come to a certain degree of length ; after which , the longer it is made , the weaker it becomes , so that every degree further , makes it shoot shorter and shorter , whereas before it came to such a degree of length , it shot further and further : Give me leave to tell you , Madam , that this question would be put more properly to a Mathematician , then to me , who am ignorant in the Mathematicks : However , since you are pleased to desire my opinion thereof , I am willing to give it you . There are , in my judgment , but three reasons which do produce this alteration : The one may be the compass of the stock , or barrel , which being too wide for the length , may weaken the force , or being too narrow for the length , may retard the force ; the one giving liberty before the force is united , the other inclosing it so long by a streight passage , as it loses its force before it hath liberty ; so that the one becomes stronger with length , the other weaker with length . The second reason , in my opinion , is , That degrees of strength may require degrees of the medium . Lastly , It may be , that Centers are required for degrees of strength ; if so , every medium may be a Center , and the middle length to such a compass may be a Center of such a force . But many times the force being weaker or stronger , is caused by the good or ill making of the Powder , or Locks , or the like . But , Madam , such questions will puzle me as much as those of Mr V. Z. concerning those glasses , one of which being held close in ones hand , and a little piece being broke of its tail , makes as great a noise as the discharging of a Gun : Wherefore I beseech you , Madam , do not trouble my brain with Mathematical questions , wherein I have neither skill , learning , nor experience by Practice ; for truly I have not the subtilty to find out their mystery , nor the capacity to understand arts , no more then I am capable to learn several languages . If you command me any thing else I am able to do , assure your self , there is none shall more readily and cheerfully serve you then my self ; who am , and shall ever continue ,

I Have heard that Artists do glory much in their Glasses , Tubes , Engines , and Stills , and hope by their Glasses and Tubes to see invisible things , and by their Engines to produce incredible effects , and by their Stills , Fire , and Furnaces , to create as Nature doth ; but all this is impossible to be done : For Art cannot arrive to that degree , as to know perfectly Natures secret and fundamental actions , her purest matter , and subtilest motions ; and it is enough if Artists can but produce such things as are for mans conveniencies and use , although they never can see the smallest or rarest bodies , nor great and vast bodies at a great distance , nor make or create a Vegetable , Animal , or the like , as Nature doth ; for Nature being Infinite , has also Infinite degrees of figures , sizes , motions , densities , rarities , knowledg , &c. as you may see in my Book of Philosophy , as also in my book of Poems , especially that part that treats of little , minute Creatures , which I there do name , for want of other expressions , Fairies ; for I have considered much the several sizes of Creatures , although I gave it out but for a fancy in the mentioned book , lest I should be thought extravagant to declare that conception of mine for a rational truth : But if some small bodies cannot be perfectly seen but by the help of magnifying glasses , and such as they call Microscopia ; I pray , Nature being Infinite , What figures and sizes may there not be , which our eyes with all the help of Art are not capable to see ? for certainly , Nature hath more curiosities then our exterior senses , helped by Art , can perceive : Wherefore I cannot wonder enough at those that pretend to know the least or greatest parts or creatures in Nature , since no particular Creature is able to do it . But concerning Artists , you would fain know , Madam , whether the Artist be beholden to the conceptions of the Student ? To which I return this short answer : That , in my judgment , without the Students conceptions , the Artist could not tell how to make experiments : The truth is , the conceptions of studious men set the Artists on work , although many Artists do ungratefully attribute all to their own industry . Neither doth it always belong to the studious Concepter to make trials or experiments , but he leaves that work to others , whose time is not so much imployed with thoughts or speculations , as with actions ; for the Contemplator is the Designer , and the Artist the Workman , or Labourer , who ought to acknowledg him his Master , as I do your Ladiship , for I am in all respects ,

YOur Command in your last was to send you my opinion concerning the division of Religions , or of the several opinions in Religions , I suppose you mean the division of the Religion , not of Religions ; for certainly , there is but one divine Truth , and consequently but one true Religion : But natural men being composed of many divers parts , as of several motions and figures , have divers and several Ideas , which the grosser corporeal motions conceive to be divers and several gods , as being not capable to know the Great and Incomprehensible God , who is above Nature . For example : Do but consider , Madam , what strange opinions the Heathens had of God , and how they divided him into so many several Persons , with so many several bodies , like men ; whereas , surely God considered in his Essence , he being a Spirit , as the Scripture describes him , can neither have Soul nor body , as he is a God , but is an Immaterial Being ; Onely the Heathens did conceive him to have parts , and so divided the Incomprehensible God into several Deities , at least they had several Deitical Ideas , or rather Fancies of him . But , Madam , I confess my ignorance in this great mystery , and honour , and praise the Omnipotent , Great , and Incomprehensible God , with all fear and humility as I ought ; beseeching his infinite mercy to keep me from such presumption , whereby I might prophane his holy Name , and to make me obedient to the Church , as also to grant me life and health , that I may be able to express how much I am ,

SInce I spake of Religion in my last , I cannot but acquaint you , that I was the other day in the company of Sir P. H. and Sir R. L. where amongst other discourses they talk'd of Predestination and Free-will . Sir P. H. accounted the opinion of Predestination not onely absurd , but blasphemous ; for , said he , Predestination makes God appear Cruel , as first to create Angels and Man , and then to make them fall from their Glory , and damn them eternally : For God , said he , knew before he made them , they would fall ; Neither could he imagine , from whence that Pride and Presumption did proceed , which was the cause of the Angels fall , for it could not proceed from God , God being infinitely Good . Sir R. L. answer'd , That this Pride and Presumption did not come from God , but from their own Nature . But , replyed Sir P. H. God gave them that Nature , for they had it not of themselves , but all what they were , their Essence and Nature , came from God the Creator of all things , and to suffer that , which was in his power to hinder , was as much as to act . Sir R. L. said , God gave both Angels and Man a Free-will at their Creation . Sir P. H. answered , that a Free-will was a part of a divine attribute , which surely God would not give away to any Creature : Next , said he , he could not conceive why God should make Creatures to cross and oppose him ; for it were neither an act of Wisdom to make Rebels , nor an act of Justice to make Devils ; so that neither in his Wisdom , Justice , nor Mercy , God could give leave , that Angels and Man should fall through sin ; neither was God ignorant that Angels and Man would fall ; for surely , said he , God knew all things , past , present , and to come : wherefore , said he , Free-will doth weaken the Power of God , and Predestination doth weaken the power of man , and both do hinder each other : Besides , said he , since God did confirm the rest of the Angels in the same state they were before , so as they could not fall afterwards , he might as well have created them all so at first . But Sir R. L. replied , That God suffered Angels and Man to fall for his Glory , to shew his Justice in Devils , and his Mercy in Man ; and that the Devils express'd God's Omnipotency as much as the Blessed . To which Sir P. H. answered , That they expressed more God's severity in those horrid torments they suffer through their Natural Imperfections , then his power in making and suffering them to sin . Thus they discoursed : And to tell you truly , Madam , my mind was more troubled , then delighted with their discourse ; for it seemed rather to detract from the honour of the great God , then to increase his Glory ; and no Creature ought either to think or to speak any thing that is detracting from the Glory of the Creator : Wherefore I am neither for Predestination , nor for an absolute Free-will , neither in Angels , Devils , nor Man ; for an absolute Free-will is not competent to any Creature : and though Nature be Infinite , and the Eternal Servant to the Eternal and Infinite God , and can produce Infinite Creatures , yet her Power and Will is not absolute , but limited ; that is , she has a natural free-will , but not a supernatural , for she cannot work beyond the power God has given her . But those mystical discourses belong to Divines , and not to any Lay-person , and I confess my self very ignorant in them . Wherefore I will nor dare not dispute God's actions , being all infinitely wise , but leave that to Divines , who are to inform us what we ought to believe , and how we ought to live . And thus taking my leave of you for the present , I rest ,

YOu are pleased to honor me so far , that you do not onely spend some time in the perusing of my Book called Philosophical Opinions , but take it so much into your consideration , as to examine every opinion of mine which dissents from the common way of the Schools , marking those places which seem somewhat obscure , and desiring my explanation of them ; All which , I do not onely acknowledg as a great favour , but as an infallible testimony of your true and unfeigned friendship ; and I cannot chuse but publish it to all the world ; both for the honour of your self , as to let every body know the part of so true a friend , who is so much concerned for the honour and benefit of my poor Works ; as also for the good of my mentioned Book , which by this means will be rendred more intelligible ; for I must confess that my Philosophical Opinions are not so plain and perspicuous as to be perfectly understood at the first reading , which I am sorry for . And there be two chief reasons why they are so : First , Because they are new , and never vented before ; for they have their original meerly from my own conceptions , and are not taken out of other Philosophers . Next , because I being a Woman , and not bred up to Scholarship , did want names and terms of Art , and therefore being not versed in the Writings of other Philosophers , but what I knew by hearing , I could not form my named Book so methodically , and express my opinions so artificially and clearly , as I might have done , had I been studious in the reading of Philosophical Books , or bred a Scholar ; for then I might have dressed them with a fine coloured Covering of Logick and Geometry , and set them out in a handsome array ; by which I might have also cover'd my ignorance , like as Stage-Players do cover their mean persons or degrees with fine Cloathes . But , as I said , I being void of Learning and Art , did put them forth according to my own conceptions , and as I did understand them my self ; but since I have hitherto by the reading of those famous and learned Authors you sent me , attained to the knowledg of some artificial Terms , I shall not spare any labour and pains to make my opinions so intelligible , that every one , who without partiality , spleen , or malice , doth read them , may also easily understand them : And thus I shall likewise endeavour to give such answers to your scruples , objections , or questions , as may explain those passages which seem obscure , and satisfie your desire . In the first place , and in general , you desire to know , Whether any truth may be had in Natural Philosophy : for since all this study is grounded upon probability , and he that thinks he has the most probable reasons for his opinion , may be as far off from truth , as he who is thought to have the least ; nay , what seems most probable to day , may seem least probable to morrow , especially if an ingenious opposer , bring rational arguments against it : Therefore you think it is but vain for any one to trouble his brain with searching and enquiring after such things wherein neither truth nor certainty can be had . To which , I answer : That the undoubted truth in Natural Philosophy , is , in my opinion , like the Philopher's Stone in Chymistry , which has been sought for by many learned and ingenious Persons , and will be sought as long as the Art of Chymistry doth last ; but although they cannot find the Philosophers Stone , yet by the help of this Art they have found out many rare things both for use and knowledg . The like in Natural Philosophy , although Natural Philosophers cannot find out the absolute truth of Nature , or Natures ground-works , or the hidden causes of natural effects ; neverthelss they have found out many necessary and profitable Arts and Sciences , to benefit the life of man ; for without Natural Philosophy we should have lived in dark ignorance , not knowing the motions of the Heavens , the cause of the Eclipses , the influences of the Stars , the use of Numbers , Measures , and Weights , the vertues and effects of Vegetables and Minerals , the Art of Architecture , Navigation , and the like : Indeed all Arts and Sciences do adscribe their original to the study of Natural Philosophy ; and those men are both unwise and ungrateful , that will refuse rich gifts because they cannot be masters of all Wealth ; and they are fools , that will not take remedies when they are sick , because Medicines can onely recover them from death for a time , but not make them live for ever . But to conclude , Probability is next to truth , and the search of a hidden cause finds out visible effects ; and this truth do natural Philosophers find , that there are more fools , then wise men , which fools will never attain to the honour of being Natural Philosophers . And thus leaving them , I rest ,

YOur desire is to know , since I say Nature is Wise , Whether all her parts must be wise also ? To which , I answer ; That ( by your favour ) all her parts are not fools : but yet it is no necessary consequence , that because Nature is infinitely wise , all her parts must be so too , no more then if I should say , Nature is Infinite , therefore every part must be Infinite : But it is rather necessary , that because Nature is Infinite , therefore not any single part of hers can be Infinite , but must be finite . Next , you desire to know , Whether Nature or the self-moving matter is subject to err , and to commit mistakes ? I answer : Although Nature has naturally an Infinite wisdom and knowledg , yet she has not a most pure and intire perfection , no , more then she has an absolute power ; for a most pure and intire perfection belongs onely to God : and though she is infinitely naturally wise in her self , yet her parts or particular creatures may commit errors and mistakes : the truth is , it is impossible but that parts or particular Creatures must be subject to errors , because no part can have a perfect or general knowledg , as being but a part , and not a whole ; for knowledg is in parts , as parts are in Matter : Besides several corporeal motions , that is , several self-moving parts do delude and oppose each other by their opposite motions ; and this opposition is very requisite in Nature to keep a mean , and hinder extreams ; for were there not opposition of parts , Nature would run into extreams , which would confound her , and all her parts . And as for delusion , it is part of Natures delight , causing the more variety ; but there be some actions in Nature which are neither perfect mistakes , nor delusions , but onely want of a clear and thorow perception : As for example ; when a man is sailing in a Ship , he thinks the shore moves from the ship , when as it is the ship that moves from the shore : Also when a man is going backward from a Looking-glass , he thinks , the figure in the Glass goeth inward , whereas it is himself that goes backward , and not his figure in the glass . The cause of it is , That the perception in the eye perceives the distanced body , but not the motion of the distance or medium ; for though the man may partly see the motion of the visible parts , yet he doth not see the parts or motion of the distance or medium , which is invisible , and not subject to the perception of sight ; and since a pattern cannot be made if the object be not visible , hence I conclude , that the motion of the medium cannot make perception , but that it is the perceptive motions of the eye , which pattern out an object as it is visibly presented to the corporeal motions in the eye ; for according as the object is presented , the pattern is made , if the motions be regular : For example ; a fired end of a stick , if you move it in a circular figure , the sensitive corporeal motions in the eye pattern out the figure of fire , together with the exterior or circular motion , and apprehend it as a fiery circle ; and if the stick be moved any otherwise , they pattern out such a figure as the fired end of the stick is moved in ; so that the sensitive pattern is made according to the exterior corporeal figurative motion of the object , and not according to its interior figure or motions . And this , Madam , is in short my answer to your propounded questions , by which , I hope , you understand plainly the meaning of ,

MADAM , Your Faithful Friend and Servant .
XXIX . MADAM ,

THe scruples or questions you sent me last , are these following . First , you desire to be informed what I mean by Phantasmes and Ideas ? I answer : They are figures made by the purest and subtilest degree of self-moving matter , that is to say , by the rational corporeal motions , and are the same with thoughts or conceptions . Next , your question is , what I do understand by Sensitive Life ? I answer : It is that part of self-moving matter , which in its own nature is not so pure and subtil as the rational , for it is but the labouring , and the rational the designing part of matter . Your third question is , Whether this sensitive self-moving matter be dense or rare ? I answer : density and rarity are onely effects caused by the several actions , that is , the corporeal motions of Nature ; wherefore it cannot properly be said , that sensitive matter is either dense , or rare ; for it has a self-power to contract and dilate , compose and divide , and move in any kind of motion whatsoever , as is requisite to the framing of any figure ; and thus I desire you to observe well , that when I say the rational part of matter is purer in its degree then the sensitive , and that this is a rare and acute matter , I do not mean that it is thin like a rare egg , but that it is subtil and active , penetrating and dividing , as well as dividable . Your fourth question is , What this sensitive matter works upon ? I answer : It works with and upon another degree of matter , which is not self-moving , but dull , stupid , and immoveable in its own nature , which I call the inanimate part or degree of matter . Your fifth question is , Whether this inanimate Matter do never rest ? I answer ; It doth not : for the self-moving matter being restless in its own nature , and so closely united and commixed with the inanimate , as they do make but one body , will never suffer it to rest ; so that there is no part in Nature but is moving ; the animate matter in it self , or its own nature , the inanimate by the help or means of the animate . Your sixth question is , If there be a thorow mixture of the parts of animate and inanimate matter , whether those parts do retain each their own nature and substance , so that the inanimate part of matter remains dull and stupid in its essence or nature , and the animate full of self-motion , or all self motion ? I answer : Although every part and particle of each degree are closely intermixed , nevertheless this mixture doth not alter the interior nature of those parts or degrees : As for example ; a man is composed of Soul , and Body , which are several parts , but joyned as into one substance , viz. Man , and yet they retain each their own proprieties and natures ; for although soul and body are so closely united as they do make but one Man , yet the soul doth not change into the body , nor the body into the soul , but each continues in its own nature as it is . And so likewise in Infinite Matter , although the degrees or parts of Matter are so throughly intermixed as they do make but one body or substance , which is corporeal Nature , yet each remains in its nature as it is , to wit , the animate part of matter doth not become dull and stupid in its nature , but remains self-moving ; and the inanimate , although it doth move by the means of the animate , yet it doth not become self-moving , but each keeps its own interior nature and essence in their commixture . The truth is , there must of necessity be degrees of matter , or else there would be no such various and several effects in Nature , as humane sense and reason do perceive there are ; and those degrees must also retain each their own nature and proprieties , to produce those various and curious effects : Neither must those different degrees vary or alter the nature of Infinite Matter ; for Matter must and doth continue one and the same in its Nature , that is , Matter cannot be divided from being Matter : And this is my meaning , when I say in my Philosophical Opinions , There is but one kind of Matter : Not that Matter is not dividable into several parts or degrees , but I say , although Matter has several parts and degrees , yet they do not alter the nature of Matter , but Matter remains one and the same in its own kind , that is , it continues still Matter in its own nature notwithstanding those degrees ; and thus I do exclude from Matter all that which is not Matter , and do firmly believe , that there can be no commixture of Matter and no Matter in Nature ; for this would breed a meer confusion in Nature . Your seventh question is , Whether that , which I name the rational part of self-moving Matter makes as much variety as the sensitive ? To which I answer : That , to my sense and reason , the rational part of animate or self-moving Matter moves not onely more variously , but also more swiftly then the sensitive ; for thoughts are sooner made , then words spoke , and a certain proof of it are the various and several Imaginations , Fancies , Conceptions , Memories , Remembrances , Understandings , Opinions , Judgments , and the like : as also the several sorts of Love , Hate , Fear , Anger , Joy , Doubt ; and the like Passions . Your eighth question is , Whether the Sensitive Matter can and doth work in it self and its own substance and degree ? My answer is , That there is no inanimate matter without animate , nor no animate without inanimate , both being so curiously and subtilly intermixt , as they make but one body ; Nevertheless the several parts of this one body may move several ways . Neither are the several degrees bound to an equal mixture , no more then the several parts of one body are bound to one and the same size , bigness , shape , or motion ; or the Sea is bound to be always at the high tide ; or the Moon to be always at the Full ; or all the Veins or Brains in animal bodies are bound to be of equal quantity ; or every Tree of the same kind to bear fruit , or have leaves of equal number ; or every Apple , Pear , or Plum , to have an equal quantity of juice ; or every Bee to make as much honey and wax as the other . Your nineth question is , Whether the Sensitive Matter can work without taking patterns ? My answer is , That all corporeal motion is not patterning , but all patterning is made by corporeal motion ; and there be more several sorts of corporeal motions then any single Creature is able to conceive , much less to express : But the perceptive corporeal motions are the ground-motions in Nature , which make , rule , and govern all the parts of Nature , as to move to Production , or Generation , Transformation , and the like . Your tenth question is , How it is possible , that numerous figures can exist in one part of matter ? for it is impossible that two things can be in one place , much less many . My answer in short is , That it were impossible , were a part of Matter , and the numerous figures several and distinct things ; but all is but one thing , that is , a part of Matter moving variously ; for there is neither Magnitude , Place , Figure , nor Motion , in Nature , but what is Matter , or Body ; Neither is there any such thing as Time : Wherefore it cannot properly be said , There was , and There shall be ; but onely , There is . Neither can it properly be said , from this to that place ; but onely in reference to the several moving parts of the onely Infinite Matter . And thus much to your Questions ; I add no more , but rest ,

MADAM , Your faithful Friend and humble Servant .
XXX . MADAM ,

IN your last , you were pleased to express , that some men , who think themselves wise , did laugh in a scornful manner at my opinion , when I say that every Creature hath life and knowledg , sense and reason ; counting it not onely ridiculous , but absurd ; and asking , whether you did or could believe , a piece of wood , metal , or stone , had as much sense as a beast , or as much reason as a man , having neither brain , blood , heart , nor flesh ; nor such organs , passages , parts , nor shapes as animals ? To which , I answer : That it is not any of these mentioned things that makes life and knowledg , but life and knowledg is the cause of them , which life and knowledg is animate matter , and is in all parts of all Creatures : and to make it more plain and perspicuous , humane sense and reason may perceive , that wood , stone , or metal , acts as wisely as an animal : As for example ; Rhubarb , or the like drugs , will act very wisely in Purging ; and Antimony , or the like , will act very wisely in Vomiting ; and Opium will act very wisely in Sleeping ; also Quicksilver or Mercury will act very wisely , as those that have the French disease can best witness : likewise the Loadstone acts very wisely ; as Mariners or Navigators will tell you : Also Wine made of Fruit , and Ale of Malt , and distilled Aqua-vitae will act very subtilly ; ask the Drunkards , and they can inform you ; Thus Infinite examples may be given , and yet man says , all Vegetables and Minerals are insensible and irrational , as also the Planets and Elements ; when as yet the Planets move very orderly and wisely , and the Elements are more active , nay , more subtil and searching then any of the animal Creatures ; witness Fire , Air , and Water : As for the Earth , she brings forth her fruit , if the other Elements do not cause abortives , in due season ; and yet man believes , Vegetables , Minerals , and Elements , are dead , dull , senseless , and irrational Creatures , because they have not such shapes , parts , nor passages as Animals , nor such exterior and local motions as Animals have : but Man doth not consider the various , intricate and obscure ways of Nature , unknown to any particular Creature ; for what our senses are not capable to know , our reason is apt to deny . Truly , in my opinion , Man is more irrational then any of those Creatures , when he believes that all knowledg is not onely confined to one sort of Creatures , but to one part of one particular Creature , as the head , or brain of man ; for who can in reason think , that there is no other sensitive and rational knowledg in Infinite Matter , but what is onely in Man or animal Creatures ? It is a very simple and weak conclusion to say , Other Creatures have no eyes to see , no ears to hear , no tongues to taste , no noses to smell , as animals have ; wherefore they have no sense or sensitive knowledg ; or because they have no head , nor brain as Man hath , therefore they have no reason , nor rational knowledg at all : for sense and reason , and consequently sensitive and rational knowledg , extends further then to be bound to the animal eye , ear , nose , tongue , head , or brain ; but as these organs are onely in one kind of Natures Creatures , as Animals , in which organs the sensitive corporeal motions make the perception of exterior objects , so there may be infinite other kinds of passages or organs in other Creatures unknown to Man , which Creatures may have their sense and reason , that is , sensitive and rational knowledg , each according to the nature of its figure ; for as it is absurd to say , that all Creatures in Nature are Animals , so it is absurd to confine sense and reason onely to Animals ; or to say , that all other Creatures , if they have sense and reason , life and knowledg , it must be the same as is in Animals : I confess , it is of the same degree , that is , of the same animate part of matter , but the motions of life and knowledg work so differently and variously in every kind and sort , nay , in every particular Creature , that no single Creature can find them out : But , in my opinion , not any Creature is without life and knowledg , which life and knowledg is made by the self-moving part of matter , that is , by the sensitive and rational corporeal motions ; and as it is no consequence , that all Creatures must be alike in their exterior shapes , figures , and motions , because they are all produced out of one and the same matter , so neither doth it follow , that all Creatures must have the same interior motions , natures , and proprieties , and so consequently the same life and knowledg , because all life and knowledg is made by the same degree of matter , to wit , the animate . Wherefore though every kind or sort of Creatures has different perceptions , yet they are not less knowing ; for Vegetables , Minerals , and Elements , may have as numerous , and as various perceptions as Animals , and they may be as different from animal perceptions as their kinds are ; but a different perception is not therefore no perception : Neither is it the animal organs that make perception , nor the animal shape that makes life , but the motions of life make them . But some may say , it is Irreligious to believe any Creature has rational knowledg but Man . Surely , Madam , the God of Nature , in my opinion , will be adored by all Creatures , and adoration cannot be without sense and knowledg . Wherefore it is not probable , that onely Man , and no Creature else , is capable to adore and worship the Infinite and Omnipotent God , who is the God of Nature , and of all Creatures : I should rather think it irreligious to confine sense and reason onely to Man , and to say , that no Creature adores and worships God , but Man ; which , in my judgment , argues a great pride , self-conceit , and presumption . And thus , Madam , having declared my opinion plainly concerning this subject , I will detain you no longer at this present , but rest ,

MADAM , Your constant Friend and faithful Servant .
XXXI . MADAM ,

I Perceive you do not well apprehend my meaning , when I say in my Philosophical Opinions * * Part. 1. c. 4. , That the Infinite degrees of Infinite Matter are all Infinite : For , say you , the degrees of Matter cannot be Infinite , by reason there cannot be two Infinites , but one would obstruct the other . My answer is ; I do not mean that the degrees of Matter are Infinite each in its self , that is , that the animate and inanimate are several Infinite matters , but my opinion is , that the animate degree of matter is in a perpetual motion , and the inanimate doth not move of it self , and that those degrees are infinite in their effects , as producing and making infinite figures ; for since the cause , which is the onely matter , is infinite , the effects must of necessity be infinite also ; the cause is infinite in its substance , the effects are Infinite in number . And this is my meaning , when I say * * Ch. 8. , that , although in Nature there is but one kind of matter , yet there are Infinite degrees , Infinite motions , and Infinite parts in that onely matter ; and though Infinite and Eternal matter has no perfect or exact figure , by reason it is Infinite , and therefore unlimited , yet there being infinite parts in number , made by the infinite variations of motions in infinite Matter , these parts have perfect or exact figures , considered as parts , that is , single , or each in its particular figure : And therefore if there be Infinite degrees , considering the effects of the animate and inanimate matter , infinite motions for changes , infinite parts for number , infinite compositions and divisions for variety and diversity of Creatures ; then there may also be infinite sizes , each part or figure differing more or less , infinite smalness and bigness , lightness and heaviness , rarity and density , strength and power , life and knowledg , and the like : But by reason Nature or Natural matter is not all animate or inanimate , nor all composing or dividing , there can be no Infinite in a part , nor can there be something biggest or smallest , strongest or weakest , heaviest or lightest , softest or hardest in Infinite Nature , or her parts , but all those several Infinites are as it were included in one Infinite , which is Corporeal Nature , or Natural Matter .

Next , you desire my opinion of Vacuum , whether there be any , or not ? for you say I determine nothing of it in my Book of Philosophical Opinions . Truly , Madam , my sense and reason cannot believe a Vacuum , because there cannot be an empty Nothing ; but change of motion makes all the alteration of figures , and consequently all that which is called place , magnitude , space , and the like ; for matter , motion , figure , place , magnitude , &c. are but one thing . But some men perceiving the alteration , but not the subtil motions , believe that bodies move into each others place , which is impossible , because several places are onely several parts , so that , unless one part could make it self another part , no part can be said to succeed into anothers place ; but it is impossible that one part should make it self another part , for it cannot be another , and it self , no more then Nature can be Nature , and not Nature ; wherefore change of place is onely change of motion , and this change of motion makes alteration of Figures .

Thirdly , you say , You cannot understand what I mean by Creation , for you think that Creation is a production or making of Something out of Nothing . To tell you really , Madam , this word is used by me for want of a better expression ; and I do not take it in so strict a sense as to understand by it , a Divine or supernatural Creation , which onely belongs to God ; but a natural Creation , that is , a natural production or Generation ; for Nature cannot create or produce Something out of Nothing : And this Production may be taken in a double sence ; First , in General , as for example , when it is said , that all Creatures are produced out of Infinite Matter ; and in this respect every particular Creature which is finite , that is , of a circumscribed and limited figure , is produced of Infinite Matter , as being a part thereof : Next , Production is taken in a more strict sense , to wit , when one single Creature is produced from another ; and this is either Generation properly so called , as when in every kind and sort each particular produces its like ; or it is such a Generation whereby one creature produces another , each being of a different kind or species , as for example , when an Animal produces a Mineral , as when a Stone is generated in the Kidneys , or the like ; and in this sence one finite creature generates or produces another finite creature , the producer as well as the produced being finite ; but in the first sence finite creatures are produced out of infinite matter .

Fourthly , you confess , You cannot well apprehend my meaning , when I say * * Part. 4. c. 10. , that the several kinds are as Infinite as the particulars ; for your opinion is , That the number of particulars must needs exceed the number of kinds . I answer : I mean in general the Infinite effects of Nature which are Infinite in number , and the several kinds or sorts of Creatures are Infinite in duration , for nothing can perish in Nature .

Fifthly , When I say , that ascending and descending Ch. 20. is often caused by the exterior figure or shape of a body ; witness a Bird , who although he is of a much bigger size and bulk then a Worm , yet can by his shape lift himself up more agilly and nimbly then a Worm ; Your opinion is , That his exterior shape doth not contribute any thing towards his flying , by reason a Bird being dead retains the same shape , but yet cannot fly at all . But , truly , Madam , I would not have you think that I do exclude the proper and interior natural motion of the figure of a Bird , and the natural and proper motions of every part and particle thereof ; for that a Bird when dead , keeps his shape , and yet cannot fly , the reason is , that the natural and internal motions of the Bird , and the Birds wings , are altered towards some other shape or figure , if not exteriously , yet interiously ; but yet the interior natural motions could not effect any flying or ascending without the help of the exterior shape ; for a Man , or any other animal , may have the same interior motions as a Bird hath , but wanting such an exterior shape , he cannot fly ; whereas had he wings like a Bird , and the interior natural motions of those wings , he might without doubt fly as well as a Bird doth .

Sixthly , Concerning the descent of heavy bodies , Ch. 21. that it is more forcible then the ascent of light bodies , you do question the Truth of this my opinion . Certainly , Madam , I cannot conceive it to be otherwise by my sense and reason ; for though Fire that is rare , doth ascend with an extraordinary quick motion , yet this motion is , in my opinion , not so strong and piercing as when grosser parts of Creatures do descend ; but there is difference in strength and quickness ; for had not Water a stronger motion , and another sort of figure then Fire , it could not suppress Fire , much less quench it . But Smoak , which is heavier then Flame , flies up , or rises before , or rather , above it : Wherefore I am still of the same opinion , that heavy bodies descend more forcibly then light bodies do ascend , and it seems most rational to me .

Lastly , I perceive you cannot believe that all bodies have weight ; by reason , if this were so , the Sun , and the Stars would have long since cover'd the Earth . In answer to this objection , I say , That as there can be no body without figure and magnitude , so consequently not without weight , were it no bigger then an atome ; and as for the Sun 's and the Stars not falling down , or rising higher , the reason is , not their being without weight , but their natural and proper motion , which keeps them constantly in their spheres ; and it might as well be said , a Man lives not , or is not , because he doth not fly like a Bird , or dive and catch fish like a Cormorant , or dig and undermine like a Mole , for those are motions not proper to his nature . And these , Madam , are my answers to your objections , which if they do satisfie you , it is all I desire , if not , I shall endeavour hereafter to make my meaning more intelligible , and study for other more rational arguments then these are , to let you see how much I value both the credit of my named Book , and your Ladiships Commands ; which assure you self , shall never be more faithfully performed , then by ,

MADAM , Your Ladiships most obliged Friend and humble Servant .
XXXII . MADAM ,

SInce my opinion is , that the Animate part of Matter , which is sense and reason , life and knowledg , is the designer , architect , and creator of all sigures in Nature ; you desire to know , whence this Animate Matter , sense and reason , or life and knowledg ( call it what you will , for it is all one and the same thing ) is produced ? I answer : It is eternal . But then you say , it is coequal with God . I answer , That cannot be : for God is above all Natural sense and reason , which is Natural life and knowledg ; and therefore it cannot be coequal with God , except it be meant in Eternity , as being without beginning and end . But if Gods Power can make Man's Soul , as also the good and evil Spirits to last eternally without end , he may , by his Omnipotency make as well things without beginning . You will say , If Nature were Eternal , it could not be created , for the word Creation is contrary to Eternity . I answer , Madam , I am no Scholar for words ; for if you will not use the word Creation , you may use what other word you will ; for I do not stand upon nice words and terms , so I can but express my conceptions : Wherefore , if it be ( as in Reason it cannot be otherwise ) that nothing in Nature can be annihilated , nor any thing created out of nothing , but by Gods special and all-powerful Decree and Command , then Nature must be as God has made her , until he destroy her . But if Nature be not Eternal , then the Gods of the Heathens were made in time , and were no more then any other Creature , which is as subject to be destroyed as created ; for they conceived their Gods , as we do men , to have Material Bodies , but an Immaterial Spirit , or as some Learned men imagine , to be an Immaterial Spirit , but to take several shapes , and so to perform several corporeal actions ; which truly is too humble and mean a conception of an Immaterial Being , much more of the Great and Incomprehensible God ; which I do firmly believe is a most pure , all-powerful Immaterial Being , which doth all things by his own Decree and Omnipotency without any Corporeal actions or shapes , such as some fancy of Daemons and the like Spirits . But to return to the former question ; you might as well enquire how the world , or any part of it was created , or how the variety of creatures came to be , as ask how Reason and sensitive corporeal Knowledg was produced . Nevertheless , I do constantly believe , that both sensitive and rational Knowledg in Matter was produced from God ; but after what manner or way , is impossible for any creature or part of Nature to know , for Gods wayes are incomprehensible and supernatural . And thus much I believe , That as God is an Eternal Creator , which no man can deny , so he has also an Eternal Creature , which is Nature , or natural Matter . But put the case Nature or natural Matter was made when the World was created , might not God give this Natural Matter self-motion , as well as he gave self-motion to Spirits and Souls ? and might not God endue this Matter with Sense and Reason , as well as he endued Man ? Shall or can we bind up Gods actions with our weak opinions and foolish arguments ? Truly , if God could not act more then Man is able to conceive , he were not a God of an infinite Power ; but God is Omnipotent , and his actions are infinite , supernatural , and past finding out ; wherefore he is rather to be admired , adored and worshipped , then to be ungloriously discoursed of by vain and ambitious men , whose foolish pride and presumption drowns their Natural Judgment and Reason ; to which leaving them , I rest ,

MADAM , Your Faithful Friend and Servant .
XXXIII . MADAM ,

IN obedience to your commands , I here send you also an explanation and clearing of those places and passages in my Book of Philosophy , which in your last Letter you were pleased to mark , as containing some obscurity and difficulty of being understood .

First , When I say , Nature is an Individable Matter , I do not mean as if Nature were not dividable into Part. 3. e. 13. parts ; for because Nature is material , therefore she must also needs be dividable into parts : But my meaning is , that Nature cannot be divided from Matter , nor Matter from Nature , that is , Nature cannot be Immaterial , nor no part of Nature , but if there be any thing Immaterial , it doth not belong to Nature . Also when I call Nature a Multiplying Figure ; I mean , Ibid. that Nature makes infinite changes , and so infinite figures .

Next , when I say , There are Infinite Divisions in Nature ; my meaning is not , that there are Infinite Part. 1. c. 11. divisions of one single part , but that Infinite Matter has Infinite parts , sizes , figures , and motions , all being but one Infinite Matter , or corporeal Nature . Also when I say single parts , I mean not parts subsisting by themselves , precised from each other , but single , that is , several or different , by reason of their different figures . Likewise , when I name Atomes , I mean small parts of Matter ; and when I speak ofPlace and Time , I mean onely the variation of corporeal figurative motions .

Again : when I say , Nature has not an absolute Part. 1. c. 13 , 14. Power , because she has an Infinite power ; I mean by absolute , as much as finite , or circumscribed ; and in this sense Nature cannot have an absolute power , for the Infiniteness hinders the absoluteness ; but when in my former Letters I have attributed an absolute Power onely to God , and said that Nature has not an absolute power , but that her power , although it be Infinite , yet cannot extend beyond Nature , but is an Infinite natural power ; I understand by an absolute Power , not a finite power , but such a power which onely belongs to God , that is , a supernatural and divine power , which power Nature cannot have , by reason she cannot make any part of her body immaterial , nor annihilate any part of her Creatures , nor create any part that was not in her from Eternity , nor make her self a Deity ; for though God can impower her with a supernatural gift , and annihilate her when he pleases , yet she is no ways able to do it her self .

Moreover , when I say , That one Infinite is contained within another ; I mean , the several sorts of Infinites , P. 1. c. 8. as Infinite in number , Infinite in duration ; as also the Infinite degrees , motions , figures , sizes , compositions , divisions , &c. all which are contained in the Infinite body of Nature , which is the onely Infinite in quantity or substance , neither can the parts of Nature go beyond Infinite .

Also when I say , That Matter would have power over Infinite , and Infinite over Matter , and Eternal over P. 6. c. 3. both ; I mean , that some corporeal actions endeavour to be more powerful then others , and thus the whole strives to over-power the parts , and the parts the whole : As for example , if one end of a string were tied about the little finger of ones hand , and the other end were in the power of the other whole hand , and both did pull several and opposite ways ; certainly , the little finger would endeavour to over-power the hand , and the hand again would strive to over-power the little finger : The same may be said of two equal figures , as two hands , and other the like examples may be given . And this is also my meaning , when I say , that some shapes have power over others , and some degrees and temperaments of matter over others ; whereby I understand nothing else , but that some parts have power over others . Also when I say P. 3. 6. 10. , that outward things govern , and a Creature has no power over it self , I mean , that which is stronger , by what means soever , is superior in power .

When I say P. 1. Ch. 3. , That the Animate part of Matter is not so gross an Infinite as the Inanimate , I do not attribute an Infiniteness to a part , as if animate matter considered as a part were infinite ; but my meaning is , that the Animate matter produces infinite effects : For , it being the Designer , Architect , and Creator of all Figures , as also the Life and Soul of all Creatures , it must needs be infinite in its effects , as also infinite in its duration . But you may object , That a part cannot produce infinite effects . I answer , It is true , if animate matter should be considered in it self without the inanimate , it could not produce infinite effects , having nothing to work upon and withal ; but because there is such a close and inseparable conjunction of those parts of matter , as they make but one body , and that Infinite , none can be or work without the other , but both degrees of matter , which make but one infinite Nature , are required in the production of the infinite effects and figures in Nature : Nevertheless , since the Animate part of Matter is the onely architect , creator , or producer of all those effects , by reason it is the self-moving part , and the Inanimate is onely the instrument which the Animate works withal , and the materials it works upon , the Production of the infinite effects in Nature is more fitly ascribed to the Animate then the Inanimate part of matter ; as for example , If an architect should build an house , certainly he can do nothing without materials , neither can the materials raise themselves to such a figure as a house without the help of the architect and workmen , but both are of necessity required to this artificial production ; nevertheless , the building of the house is not laid to the materials , but to the architect : the same may be said of animate and inanimate matter in the production of natural effects . Again , you may reply , That the animate and inanimate parts of matter are but two parts , and the number of Two is but a finite number , wherefore they cannot make one infinite body , such as I call Nature or natural Matter . I answer , Madam , I confess , that a finite number is not nor cannot make an infinite number ; but I do not say , that the animate and inanimate parts or degrees of matter are two finite parts each subsisting by it self as circumscribed , and having its certain bounds , limits and circumference ; for if this were so , certainly they being finite themselves , could not produce but finite effects ; but my meaning is , that both the animate and inanimate matter do make but one Infinite bulk , body , or substance , and are not two several and dividable bodies in themselves , and thus they may be divided not into two , but into Infinite parts ; Neither are they two different Matters , but they are but one Matter ; for by the animate Matter I do understand self-motion ; and that I call this self-motion Matter , the reason is , that no body shall think as if self-motion were immaterial ; for my opinion is , that Nature is nothing but meer Matter , and that nothing is in Nature which is a part of Nature , that is not material ; wherefore to avoid such a misapprehension ( seeing that most learned men are so much for abstractions and immaterial beings ) I called self-motion animate matter , or the animate part of matter ; not as if they were two several matters , but that all is but one natural Matter , or corporeal Nature in one bulk , body , or substance , just like as the soul and body do make but one man ; and to avoid also this misapprehension , lest they might be taken for several matters , I have upon better consideration , in this volume of Philosophical Letters , call'd the animate matter corporeal self-motion , which expression , I think , is more proper , plain , and intelligible then any other : Neither would I have you to scruple at it , when I say , that both parts or degrees of animate and inanimate matter do retain their own interior natures and proprieties in their commixture , as if those different natures and proprieties , where one is self-moving , and the other not , did cause them to be two different matters ; for thus you might say as well , that several figures which have several and different interior natures and proprieties , are so many several matters . The truth is , if you desire to have the truest expression of animate and inanimate matter , you cannot find it better then in the definition of Nature , when I say , Nature is an infinite self-moving body ; where by the body of Nature I understand the inanimate matter , and by self-motion the animate , which is the life and soul of Nature , not an immaterial life and soul , but a material , for both life , soul and body are and make but one self-moving body or substance which is corporeal Nature . And therefore when I call Animate matter an Extract , I do it by reason of its purity , subtilty P. 4. ● . 3 , 32. and agility , not by reason of its immateriality . Also when I name the word Motion by it self , and without any addition , I understand corporeal Motion ; and when I name Motion , Matter and Figure , I do not mean three several and distinct things , but onely figurative corporeal motion , or figurative self-moving matter , all being but one thing ; the same when I speak of Place , Time , Magnitude , and the like .

Concerning Natural Production or Generation ; when I say , The same matter or figure of the producers P. 1. c. 22. doth not always move after one and the same manner in producing , for then the same producers would produce one and the same creature by repetition , I do not mean the very same creature in number , unless the same motions and parts of matter did return into the producers again , which is impossible ; but I understand the like creature , to wit , that one and the same sort of particular motions would make all particular figures resemble so , as if they were one and the same creature without any difference .

When I say , Sensitive and Rational knowledg lives in P. 3. c. 15. sensitive and rational Matter , and Animate liveth in Inanimate matter , I mean they are all several parts and actions of the onely infinite matter inseparable from each other ; for wheresoever is matter , there is also self-motion , and wheresoever is self-motion , there is sense and reason , and wheresoever is sense and reason , there is sensitive and rational knowledge , all being but one body or substance , which is Nature ,

When I say , The death of particular Creatures causes Ibid. an obscurity of Knowledge , and that particular Knowledges increase and decrease , and may be more or less , I mean onely that parts divide themselves from parts , and joyn to other parts ; for every several Motion is a several Knowledge , and as motion varies , so doth knowledge ; but there is no annihilation of any motion , and consequently not of knowledge in Nature . And as for more or less knowledge , I mean more or less alteration and variety of corporeal figurative motions , not onely rational but sensitive , so that that creature which has most variety of those perceptive motions is most knowing , provided they be regular , that is , according to the nature and propriety of the figure , whether animal , vegetable , mineral , or elemental ; for though a large figure is capable of most knowledge , yet it is not commonly or alwayes so wise or witty as a less , by reason it is more subject to disorders and irregularities ; like as a private Family is more regular and better ordered then a great State or Common-wealth . Also when I say , That some particular Knowledge lasts longer then some other , I mean that some corporeal motions in some parts do continue longer then in others .

When I say , A little head may be full , and a great P. 6. c. 11 , head may be empty of rational matter , I mean there may be as it were an ebbing or flowing , that is more or less of Rational Matter joyned with the Sensitive and Inanimate : And when I say , That , if all the heads of Mankind were put into one , and sufficient quantity of Rational Matter therein , that Creature would not onely have the knowledge of every particular , but that Understanding and Knowledge would increase like Use-money , my meaning is , that if there were much of those parts of rational matter joyned , they would make more variety by selfchange of corporeal motions .

When I name Humane sense and reason , I mean such sensitive and rational perception and knowledge as is proper to the nature of Man ; and when I say Animal sense and reason , I mean such as is proper to the nature of all Animals ; for I do not mean that the sensitive and rational corporeal motions which do make a man , or any Animal , are bound to such figures eternally , but whilest they work and move in such or such figures , they make such perceptions as belong to the nature of those figures ; but when those self-moving parts dissolve the figure of an Animal into a Vegetable or any other Creature , then they work according to the nature of that same figure , both exteriously and interiously .

When I say , That Place , Space , Measure , Number , Weight , Figures , &c. are mixed with Substance , P. 3. c. 27. I do not mean they are incorporeal , and do inhere in substance as so many incorporeal modes or accidents ; but my meaning is , they are all corporeal parts and actions of Nature , there being no such thing in Nature that may be called incorporeal ; for Place , Figure , Weight , Measure , &c. are nothing without Body , but Place and Body are but one thing , and so of the rest . Also when I say , That sometimes Place , C. 14. sometimes Time , and sometimes Number gives advantage , I mean , that several parts of Matter are getting or losing advantage .

When I say , an Animal or any thing else that has exterior local motion , goeth or moveth to such or such P. 5. c. 51. a place , I mean , to such or such a body ; and when such a Creature doth not move out of its place , I mean , it doth not remove its body from such or such parts adjoyning to it .

When I say , The rational animate matter divides it self into as many parts , and after as many several manners P. 6. c. 8. as their place or quantity will give way to , I mean their own place and quantity : also , as other parts will give way to those parts , for some parts will assist others , and some do obstruct others .

When I say , That the Nature of extension or dilation strives or endeavours to get space , ground , or compass , P. 4. c. 34. I mean those corporeal motions endeavour to make place and space by their extensions , that is , to spread their parts of matter into a larger compass or body . And when I say , That Contractions endeavour to cast or thrust out space , place , ground , or compass , My meaning is , That those corporeal motions endeavour to draw their parts of matter into a more close and solid body , for there is no place nor space without body .

Also when I name several tempered substances and matters , I mean several changes and mixtures of corporeal Ibid. motions .

Also when I speak of Increase and Decrease , I mean onely an alteration of corporeal figurative motions , as uniting parts with parts , and dissolving or separating parts from parts .

When I say , That the motions of cold , and the motions of moisture , when they meet , make cold and P. 5. c. 4. moist effects , and when the motions of heat and moisture meet , make hot and moist effects ; and so for the motions of cold and dryness : I mean , that when several parts do joyn in such several corporeal motions , they cause such effects ; and when I say cold and heat presses into every particular Creature , I mean , that every Creatures natural and inherent perceptive motions make such patterns as their exterior objects are , viz. hot or cold , if they do but move regularly , for if they be irregular , then they do not : as for example ; those in an Ague will shake for cold in a hot Summers day , and those that are in a Fever will burn with heat , although they were at the Poles .

When I say , that hot motions , and burning motions , and hot figures , and burning figures do not associate or P. 5. c. ●3 . joyn together in all Creatures : I mean , that the corporeal motions in some figures or creatures , do act in a hot , but not in a burning manner ; and when I say , some creatures have both hot and burning motions and figures , I mean , the corporeal motions act both in a hot and burning manner ; for though heat is in a degree to burning , yet it is not always burning , for burning is the highest degree of heat , as wetness is the highest degree of moisture .

When I say , Warmth feeds other Creatures after a P. 5. c. 27. spiritual manner , not a corporeal , My meaning is , not as if heat were not corporeal , but that those corporeal motions which make heat work invisibly , and not visibly like as fire feeds on fuel , or man on meat .

Also when I say , Excercise amongst animals gets Ibid. strength , I mean , that by excercise the inherent natural motions of an animal body are more active , as being more industrious .

When I say , That the passage whence cold and sharp T. 5. c. 45. winds do issue out , is narrow , I mean , when as such or such parts disjoyn or separate from other parts ; as for example , when dilating parts disjoyn from contracting parts ; and oftentimes the disjoyning parts do move according to the nature of those parts they disjoyn from .

Concerning the actions of Nature , my meaning is , that there is not any action whatsoever , but was always in Nature , and remains in Nature so long as it pleases God that Nature shall last , and of all her actions Perception and self-love are her prime and chief actions ; wherefore it is impossible but that all her particular creatures or parts must be knowing as well as self-moving , there being not one part or particle of Nature that has not its share of animate or self-moving matter , and consequently of knowledge and self-love , each according to its own kind and nature ; but by reason all the parts are of one matter , and belong to one body , each is unalterable so far , that although it can change its figure , yet it cannot change or alter from being matter , or a part of Infinite Nature ; and this is the cause there cannot be a confusion amongst those parts of Nature , but there must be a constant union and harmony betwixt them ; for cross and opposite actions make no confusion , but onely a variety ; and such actions which are different , cross and opposite , not moving always after their usual and accustomed way , I name Irregular , for want of a better expression ; but properly there is no such thing as Irregularity in Nature , nor no weariness , rest , sleep , sickness , death or destruction , no more then there is place , space , time , modes , accidents , and thelike , any thing besides body or matter .

When I speak of unnatural Motions , I mean such as are not proper to the nature of such or such a Creature , P. 7. c. 11. as being opposite or destructive to it , that is , moving or acting towards its dissolution . Also when I call Violence supernatural , I mean that Violence is beyond the particular nature of such a particular Creature , that is , beyond its natural motions ; but not supernatural , that is beyond Infinite Nature or natural Matter .

When I say , A thing is forced , I do not mean that the forced body receives strength without Matter ; but that some Corporeal Motions joyn with other Corporeal Motions , and so double the strength by joyning their parts , or are at least an occasion to make other parts more industrious .

By Prints I understand the figures of the objects which are patterned or copied out by the sensitive and rational corporeal figurative Motions ; as for example , when the sensitive corporeal motions pattern out the figure of an exteriour object , and the rational motions again pattern out a figure made by the sensitive motions , those figures of the objects that are patterned out , I name Prints ; as for example , The sense of Seeing is not capable to receive the Print , that is , the figure or pattern P. 3. c. 2. of the object of the whole Earth . And again , The rational Motions are not alwayes exactly after the sensitive Prints , that is , after the figures made by the sensitive motions . Thus by Prints I understand Patterns , and by printing patterning ; not that the exteriour object prints its figure upon the exteriour sensitive organs , but that the sensitive motions in the organs pattern out the figure of the object : but though all printing is done by the way of patterning , yet all patterning is not printing . Therefore when I say , that solid bodies print their figures in that which is more porous and soft , and P. 5. c. 23. that those solid bodies make new prints perpetually ; and as they remove , the prints melt out , like verbal or vocal sounds , which print words and set notes in the Air ; I mean , the soft body by its own self-motion patterns out the figure of the solid body , and not that the solid body makes its own print , and so leaves the place of its own substance with the print in the soft body ; for place remains always with its own body , and cannot be separated from it , they being but one thing : for example ; when a Seal is printed in Wax , the Seal gives not any thing to the Wax , but is onely an object patterned out by the figurative motions of the Wax in the action of printing or sealing .

When I make mention of what the Senses bring in , I mean what the sensitive Motions pattern out of forreign P. 6. c. 13. objects : And when I say , that the pores being shut , touch cannot enter , I mean , the sensitive corporeal P. 7. c. 12. motions cannot make patterns of outward objects .

Also when I say , our Ears may be as knowing as our Eyes , and so of the rest of the sensitive organs ; I mean the sensitive motions in those parts or organs .

When I say , The more the Body is at rest , the more active or busie is the Mind , I mean when the sensitive P. 6. c. 13. Motions are not taken up with the action of patterning out forreign objects .

When I say , the Air is fill'd with sound , and that words are received into the ears , as figures of exterior P. 6. c. 29. objects are received into the eyes , I mean , the sensitive motions of the Air pattern out sound , and the sensitive motions of the Ears pattern out words , as the sensitive figurative motions of the Eyes pattern out the figures of external objects .

Also when I speak of Thunder and Lightning , to wit , That Thunder makes a great noise by the breaking of lines : My meaning is , That the Air patterns out this sound or noise of the lines ; and by reason there are so many patterns made in the air by its sensitive motions , the Ear cannot take so exact a copy thereof , but somewhat confusedly ; and this is the reason why Thunder is represented , or rather pattern'd out with some terrour ; for Thunder is a confused noise , because the patterns are made confusedly .

But concerning Sound and Light , I am forced to acquaint you , Madam , that my meaning thereof is not so well expressed in my Book of Philosophy , by reason I was not of the same opinion at that time when I did write that Book which I am now of ; for upon better consideration , and a more diligent search into the causes of natural effects , I have found it more probable , that all sensitive perception is made by the way of Patterning , and so consequently the perception of Sound and of Light ; wherefore , I beseech you , when you find in my mentioned Book any thing thereof otherwise expressed , do not judg of it as if I did contradict my self , but that I have alter'd my opinion since upon more probable reasons .

Thus , Madam , you have a true declaration of my sence and meaning concerning those places , which in my Philosophical Opinions you did note , as being obscure ; but I am resolved to bestow so much time and labour as to have all other places in that Book rectified and cleared , which seem not perspicuous , left its obscurity may be the cause of its being neglected : And I pray God of his mercy to assist me with his Grace , and grant that my Works may find a favourable acceptance . In the mean time , I confess my self infinitely bound to your Ladyship , that you would be pleased to regard so much the Honour of your Friend , and be the chief occasion of it ; for which I pray Heaven may bless , prosper , and preserve you , and send me some means and ways to express my self ,

MADAM , Your thankfull Friend , and humble Servant .
ETernal God , Infinite Deity , Thy Servant , NATURE , humbly prays to Thee , That thou wilt please to favour Her , and give Her parts , which are Her Creatures , leave to live , That in their shapes and forms , what e're they be , And all their actions they may worship thee : For 't is not onely Man that doth implore , But all Her parts , Great God , do thee adore ; A finite Worship cannot be to thee , Thou art above all finites in degree : Then let thy Servant Nature mediate Between thy Justice , Mercy , and our state , That thou may'st bless all Parts , and ever be Our Gracious God to all Eternity .
FINIS .
