clammyness humidity and viscousness do stupifie the Animal Spirits and Sleep is sweet or restless according as those Vapours are sweet or abound with Corpuscles or are stirred up from Choler or other things of an irregular Figure or where some emancipated Atoms make the disturbance The mixture of these Atoms is often the Cause of Light-headedness Madness and Hypochondriac Melancholly and they likewise produce watchfulness by an inversion and confusion of the Ideas in the imagination from whence it happens that we see that which we never see directly and sometimes Monsters and horrible things This motion of the Images or Ideas is sometimes so very violent and there is so great a Troop of these emancipated Atoms in the Brain that those that are asleep do sometimes rise out of Bed Talk climbe up Walls Bathe themselves and then go to Bed again without ever waking all the while Death is commonly called a perpetual Sleep and in Animals excepting Man it is nothing else than a total dissipation of the Vital Atoms or a cessation of motion in which their Life consists In Man these things are not after the same manner although however all these things cease in a dying Man either immediately as in a violent Death or by degrees as in a Natural Death we must confess nevertheless that in that respect something else is to be accomplished to wit the separation of the Soul which God gave him and which returns unto him that gave it Before we go any further and that we may make an end of this Chapter and be as good as our Word I am forced a little more specially to discourse concerning the Death of those things which have Life For whatsoever is Created and Compounded of many Parts and Liveth is subject to Death Man who is Compounded of a material and Organical Body like other Beings dyes at last but because he hath an immortal Soul Created after the Image of God he only dyes that he may live Eternally with God if he be Faithful and his Death is no more than Sleep and a passing into Eternity What a Christian Philosopher ought to think of this Soul I shall declare in the last Chapter of this Book Here I will say something of his Body as also of its Corruption and Dissolution The Rational Soul never goes out of this Mortal Body before the motion of the Heart is stopped this motion which is not voluntary ceasing Life can no longer continue since it consists in this motion If the Rational Soul was only in the Brain as Duncan and some others will have it it would be hard to tell why it should depart upon the cessation of the Hearts motion whilst the rest of the Parts are in good order As for my part I consider it in its Spiritual Nature believing that he must have too mean an Idea of this Spiritual Substance who confines it to the Brain and to the smallest part of it That Opinion which affirms it to be present every where in the whole Body although it operates more particularly in the Brain and Heart seems to me to be more Reasonable and for this Reason the Soul acting in the Heart the Organ ceasing it departs in the same Moment It may seem a wonder to not a few that the Rational Soul should so depend upon the material Body but since it so seemed good to the Author of Nature we ought to rest satisfied The Body is endued with Organs for the sake of the Soul and the Soul is created for the sake of the Body and one is made for the other and the Conjunction of these two make a compleat Man. One part onely does not make a Man nor does a separate Body make up the Essence of a Man and indeed a dead Man is not what he was 'till he Rises again The Soul therefore is annexed to the Body by such a sort of Tye that it cannot act but by Organs So that he sees nothing when his Eyes are out he hears nothing when his Ears are stopt and the chief Organ being deficient the Soul departs because it can do nothing This Chief Organ to wit the Heart is deficient many ways it may be stopped and suffocated for want of Air and respiration for the Atoms of Light implanted in the Heart at the time of a Man's Conception the commerce of the Solar Spirits being intercepted for want of Air do sometimes suddenly stand still they flye away finding a passage through a solution of the continuum or through Pores made fit by a burning Feaver in the Heart all the Water of the Pericardium being dryed up Thick and viscous Blood does sometimes stop the motion of these Vital Atoms Poyson also does by its acute Particles pierce through the Heart and give an exit to these Spirits of Light which are tyed to those which the Sun bestows upon us and are attracted by them returning thither from whence they came Let us see now what the Body does in the Grave it putrifies there that is it is dissolved some Corpuscles or Atoms withdraw themselves some part of the Body is changed into Worms some of the Vital Spirits resisting It is a folly here to imagine any substantial form of the Dead Carcasse or to acknowledge partial forms of the Bones Flesh Veins Arteries and such like things Subjects to the form of the dead Carcasse or alone without this Form. These are Illusions and Chimera's Matter is the same and all the change that happens consists in this That when the Rational Soul is absent there remains nothing besides matter the Organs by little and little lose their Figure and having lost their Composition they lose their action that which was compounded is dissolved and the greater part goes into Dust and Ashes the Luminous Spirits recede and follow the motion of the Spirits of their kind some Parts or Corpuscles joyned to the putrifying Body purtifie in the place where they are Experience favours this Doctrine A certain Servant to a Noble-Man whose Nose had been by great misfortune newly cut off freely parts with his own Nose to serve his Master This Nose being put in the place of that which was newly cut off took Root and grew together after such a manner with a Cartaliginous Flesh that it seemed to be Natural About twenty years afterwards the Servant dyes in a far Countrey and was Buried and as by degrees he putrified so after the same manner this end of a Nose began to putrifie to be corrupted and to fall off parting from that part to which it had so long stuck without withering whilst the Servant lived the part following the condition of the whole I say moreover that the least parts or Corpuscles which proceed from a Body the Body being Dead and Corrupted they also are Corrupted and joyned in commerce with Atoms of the same Nature which they do by inviting them to joyn and come together And here 's an Experiment which every one can understand It is
Therefore the motions of Atoms are neither equal nor every where alike but they do vary according to the diversity of Bodies whereby they are driven or as the figures of them are more or less fitted for motion or otherwise according to the proportion of Vacuities which are dispersed in bodies So that some Atoms are moved quicker and others slower not because some are heavier than others but because they are driven backwards and forwards or are stopped by others which do fix them with the greater or less violence CHAP. XXI Difficulties arising from the Doctrine of Atoms THE first which presents it self is in relation to the Being and Nature of Atoms therefore it is hard to conceive that an Atom is corporeal and material and at the same time that it is indivisible or that the same being indivisible should at the same time have its grossness and extension but this difficulty proceeds from nothing else but the prejudice of our Senses which can conceive no Objects but as they are divisible and gross neither can they give to our Soul which is an indivisible being an Idea of an indivisible thing It is only our Soul which is indivisible as well as an Atom is able to conceive the nature of them which being elevated above the Senses can correct the Errors of them therefore I say that an Atom is not a body according to the Notion which we have of it that it is a compound Being but I affirm it to be a simple Being and also Corporeal that is to say simple because it is indivisible and corporeal because it hath a certain extension and makes up the composition of bodies which in the total division of them are reduced again into Atoms There are two other difficulties which do arise from the former for if an Atom be indivisible after what manner can we propose to our selves that it hath extension or how can it be an ingredient in the composition of divisible bodies To which it is answered in few words That extension is according to the nature of the thing extended for if the thing extended be divisible in the same manner is the extension and so on the other side so it is of the rational Soul which is possessed of the whole body and exercises its operations in all the parts of it nevertheless it is like an Atom indivisible and though it be divisible in respect of the space it occupies yet it hath an internal extension which is indivisible It is the same thing which Divines are forced to say of Angels and some Philosophers about their Physical tumid points But some will say that Atoms are like neither to Souls Angels or Physical Points because they have parts and these have none because that which doth consist of parts is divisible it follows also that an Atom is divisible To this difficulty I answer with the Divines That Angels and our Souls which are Spirits and also with Philosophers that physical Points which are material have no real but only potential parts that is an Angel and the rational Soul in respect of the operations which they exercise and the space which they occupy and the tumid points in respect of the space which they fill up Indeed an Angel and the Soul have two powers whereof the one is the Intellect the other the Will which being no more but an indivisible substance which are capable of understanding and willing yet no Man will deny but that they notwithstanding their indivisibility which at least is equal to the indivisibility of an Atom do fill up a divisible space as no Man can doubt but that an Angel can be at the same time in the four corners of the Room and likewise can be in the middle of it and that it hath a foursquare figure by communication with the four Angles or Corners and that it can quit this and assume another figure at its pleasure which cannot be said of tumid points and Atoms which are destitute of Understanding and Will The rational Soul being equally indivisible with an Atom Angel or point doth wholly possess a great body no less than it did then when the body was little therefore it does dilate it self without being divided because in its nature it is simple and indivisible and is without distinct parts This is the Opinion of Aristotle and indeed it is the most common Opinion But if the Soul were not by its own substance extended through the whole body and had its seat only in the Heart as Empedocles would have it or in the Spleen and the Stomach as Van Helmont places it or in the Glaudula Pinealis of the Brain according to Cartesius or in the Striate bodies of the Brain where the common sense is or the sense it self as it is called by way of excellency and in the Callous parts because there it forms the Ideas of things and judges of them and in the cineritious part of the Brain because there it performs the functions of the memory according to the Opinion of Duncane It is certain that all these parts which are taken to be the feat of the Soul are divisible and that they have distinct parts and figures so the Soul as it is indivisible occupies a space or place which is divisible whence I conclude that the indivisibility does not hinder but that a substance may have a certain indivisible extension but divisible as to the place which it possesses or that it may have Angles and figures in respect of place though its substance essentially remain one simple and indivisible Delugo and his followers do apply this Doctrine to tumid points and truly I conceive I may take the same liberty to apply it to Atoms from this Principle which is that an Angel or the rational Soul are neither more simple nor more indivisible than a material Atom as we have supposed it and laid it down as a Principle To these I add that it is not sufficient that any thing be divisible because it hath Parts but they ought to be Physically distinct and joined together by a Physical Union nor that each of these Parts should be of the same Essence with the whole Compound whereof they are parts But it is certain that the Parts of an Atom are not Physically distinct for the one could neither be nor cease to be without the other no more than the two Essential Perfections of Man that is to be an Animal and Rational Creature And briefly the Parts of an Atom are the Parts of a Simple Being which are in Unity but not in Union and by Consequence really inseparable which is no hindrance but that the Mind of a Man may be able to conceive some kind of interval and some diversity betwixt the Parts of an Atom in the same manner as the Animal and Rational Natures are represented in a Man as if they were two Physically distinct things Gassendus Reasons from another Principle which is very solid and built upon the solidity
in general THE Earth as hath been said is a Planet habitable having three Motions The First of these is about its own proper Centre which is not the Centre of the World for the Circle of the Earth is Excentrick This motion is impressed upon it by the Solar Vortex as a greater Wheel carries a less along with it and this is called its Diurnal motion Another is about the Sun as the Centre of the World to which it is Concentrical and requires a Years time to return to the same point and this arises likewise from the Solar Vortex for the Earth being driven on by the Flux of the Centre of the Universe cannot be moved about its proper Centre without sensibly making an Excentrick Circle And from this two-fold Motion of it arises the other third viz. from one Pole to the other in the space of one six Months and returning back again in the space of six other which happens because it can go no farther nor pass the Tropick unless it recedes from the Solar Circle for here it hath only the Latitude of the Ecliptick For if it should recede it must ascend too for whatsoever recedes from the Centre of the Universe in respect of that ascends and so likewise from its proper Centre The Earth in all these motions carries the Water along with it for they both make but one and the same Globe which is altogether exact and regular on the Seas part but less accurate on the Earth's part by reason of the Vales and Mountains And though it be true that the Earth does not seem to us to be of a round Figure yet it is proved by Experience for that teaches us that the last part of the Ship which can be seen by those on shoar is the top of the Mast and the first Things they on Ship-board see as they approach their Haven are the tops of Towers From whence it may evidently appear that the Sea is as it were a Belly and eminence which insensibly is lifted up into a convexity that so with the Earth it may constitute one entire Globe Earth and Water are two immediate Principles of all Compounds which are to be seen in this lower Region of the World yet notwithstanding not they but Atoms are the first Elements as it is said else-where There is moreover a lesser number of Vacuities in Terrestrial than in Aqueous Bodies and this is the Cause that the Earth is more solid and the Water more fluid that is to say less solid than the Earth CHAP. II. Of Terrestrial Inanimate Bodies in general THere is nothing Simple but God an Angel the Rational Soul Atoms and a Vacuum God is essentially Simple in a simplicity of Essence Power and Act for whatsoever is in him is an act his Essence is no ways compounded nor his Power idle nor his Action ever interrupted An Angel is simple in respect of essence but his power is not always in act nor his action at least the same without intermission The Rational Soul which is a Spirit laid in pledge or at least a Physical Compound with an Organical Body is simple because it hath neither Integral Physical nor contained parts but it self is a Physical Part saving only that its powers are often idle and its actions are changed and interrupted A Vacuum is simple for since it is neither a Spirit nor Matter nor any thing else but a capacity of receiving a Body and it hath an essential emptiness it cannot be called simple but for as much as it cannot suffer composition by reason of its imperfection Lastly Atoms are simple because they are indivisible and the first Elements of Bodies out of which all compound Bodies are framed I acknowledge no other Elements no other substantial material forms in Bodies for they are not only unnecessary but impossible Yet it doth not follow from thence that the diversity which occurs between Bodies constituting the World and which are the Compounds of the lower World is no other than meerly accidental and not at all essential for according to our Principles we determine one composition to be substantially distinguished from another by Atoms which are the first Principles of its composition and essentially by the manner of composition that is by the disposition and ordination of its Atoms Corpuscles and all its parts They who conclude that there is no Physical Compound without a substantial form think Matter alone with its diverse Figures and in all its dispositions cannot possibly be the Cause of the special Properties which we observe in every one Body and that therefore a form distinct from Matter is required to produce qualities proper to every one compound Body As for Example Earth is in its Nature dry and Water is cold which could not happen unless Earth did obtain a substantial form which is dryness and Water such a one as Cold requires This is that form which restores dryness to the Earth and Cold to the Water when they are put out of their Natural State and condition to wit by introducing moisture into the first and heat into the latter This Objection how strong so ever it may seem is nevertheless but vain for we say that neither the moisture of Water nor the dryness of Earth are Accidental Qualities so that this ought to gravel none but those who acknowledge Accidental Qualities distinct from Matter Ours is quite another Opinion and our Language quite otherwise For we firmly conclude That all Compound Bodies which are in the World are compounded of Matter every thing else being excluded and that all contingent changes in them arise from Matter newly added or taken away or changing place or by some confused Atoms or Corpuscles brought thither from else-where or lastly by the more notable parts changing place or other ways disposed by the Action of external Agents CHAP. III. Of the various Qualities to be observed in Compound Bodies THere is a difference betwixt the Qualities of Simple Elements which are Atoms and the Qualities of Bodies compounded of them for the First as well as Atoms are immutable and incorruptible the others as well as the compound Bodies are mutable and fleeting For indeed Propriety follows the Nature of that Being of which it is the propriety So that if Atoms are immutable by their solidity the same must be said of their Qualities but Bodies compounded of many distinct Parts are forced to be changed as often as their parts change places or are wholly separated That which is corrupted as well as that which is generated De Novo is a Composition for as corruption is a division of substance so generation is a composition of it To Explain this Opinion There is nothing more commodious than the example of Syllables and Words For truly Letters are immutable indeed and according to their different place they vary a Syllable or Word without changing their figure substance and essence remaining always the same in what state or disposition soever they are placed
run downwards For to say that Water will seek after its proper Centre is to flye back again to an Occult Cause and to renounce our Principles I conclude therefore that the Atoms Corpuscles and drops of Water are of a perfect round Figure and since they have a certain inclination without hindrance nothing can keep them back but that without interruption they do and will drive one another forward even to the World's End. The Fourth Part of Physick Of those things which are in Man and of Man himself as he is a Compound Physical Animated Body WE are now come at length to our Fourth and last part of Physick wherein according to what we proposed we are to speak of the things which are in Man whom now we consider as a Body animated Which compels us to speak of the Soul and of Life in general and afterwards descending to special we will explain the Life of Man as he is rational and we shall endeavour by Natural Reasons to prove the immortality of his Soul. CHAP. I. Of Life in general LIfe as we have said elsewhere appears only by action and motion So those Beings which have most of action and motion obtain also most of Life And we say a Man is dying when there is but little motion left in him and dead when it is quite abolished Every motion is not a vital motion for that it may be so it must be Internal of the thing that acts and proceed from a Principle that is not external Wherefore the motion of a Stone that is thrown into the Air is not a vital motion because it comes from an external Cause to wit from the hand of him that throws it I say further that it must be the motion of a Compound Body if it be a vital motion and for this Cause the motion of Atoms is not so because they are simple and indivisible beings neither capable of Life nor Death And for as much as Atoms are not Compounds tho' they compound Bodies so they are not said to live in the least although without their impression and ministery there is no Life nor no motion in the Bodies we speak of Life therefore is an action and motion of a Compound and Organical Body arising from an internal and seminal Principle And in this sense Mettals may be said to possess a certain kind of Life since they obtain a certain motion of vegetation by which they grow and we may determine this motion to arise from an internal and seminal principle though it be abstruse enough and the Organs of Life scarcely appear so that it is a very difficult matter to distinguish them in Plants and in some Animals as in the Fish called a Muscle and in Oysters which are nevertheless endowed with a more perfect life than Mettals and Plants We shall in the following Discourse tell you wherein this Life consists and how Mettals and Plants dye as well as other living Creatures There is a great difference between Life and the Principle of it tho' not in like manner between Life and motion or vital action For Life is the action and motion of divers Beings gathered by Nature together and united after such a manner as that the parts of it move one another as we see in Machines and what the Pullies and Springs are in these the same are the Spirits in Natural Compound Bodies that is the most swiftly moving Atoms From this Doctrine is collected first of all That there are Atoms more swift and fuller of Motion than others by reason of their subtilty and figure such as are Coelestial Fiery and Luminous Atoms to wit such as Heaven the Stars Fire Heat and Light are compounded of This we judge by the compound Bodies that are made and framed out of them For humane Spirits instructed with material Senses is not able to penetrate into the essence of Atoms and their special difference But we determine that the Atoms out of which Heaven the Stars and Light are made have Figures and activities greater more perfect and more fit for motion than those that compound cold and heavy Bodies although when the thing is well considered it may arise from their greater liberty and more perfect Figure Secondly according to our Principles we must say That the Vital Spirts so called are nothing else but a certain number of Atoms free from all composition and such whose Figure and condition renders them unfit for service and slavery This Doctrine supposeth that there are two sorts of Atoms in Nature some of which like Common-People are destined to Imprisonment Service and Bonds but others like Nobles to liberty and command over others Now those whose Lot it is to be like the Commons are made to compose the Machines of our Bodies and they are such as entangle one another and are linked and bound together in the formation of Bodies whereas those which cannot be bound nor undergo Slavery are destined to move the whole Machine of our Bodies as not being fastned to any part but running through all parts and bestowing every where motion sense and disposition These are what are called Vital Spirits because they bestow Life that is motion These Atoms therefore are not Life but the Principles and Authors of it Sometimes Atoms that Compound Bodies get out of Service and as often as occasion offers and Bodies â—uffer division are emancipated for in all separations and corruptions of Bodies some Atoms do flye away and like the first seek to recover Liberty and when it happens that these Fugitive Atoms are mingled together with those that are essentially free from thence arise conflicts in our Bodies and from These Ill dispositions and our Diseases which there is no help to be hoped for nor any cure unless these rebellious and emancipated Atoms are restored to their first confinement or else driven out of the Body that so by this means the Spirits may remain pure and altogether free in their motion and not be interrupted by these irregular Atoms which are the common disturbers of Nature and Health And for as much as some Atoms continually flye out of those Bodies which we use for nourishment by reason of divers degrees of Corruption which they are forced to undergo before they can be changed into our substance So it is certain that there is always in us some principle of a Disease to be found and that we never in this World enjoy a perfect Health and that those are only most healthy who are less sickly than others As I have said elsewhere that there are no Men absolutely wise but that they that are called wise are less ignorant than others But moreover if Captive Atoms are sometimes free'd by emancipation so on the other hand those which are not used to be detained are sometimes incarcerated and involved with others nor can they stir beyond the limits of their Prison And there are some which in like manner are so included with others by the Providence of
the Creator and necessity of Nature and some only by accident and the power and plenty of Matter encompassing them So the Atoms shut up in the Heart that they may give motion to it and to the whole Body were incarcerated at the beginning of its formation or rather being cast into seminal Bands when God created it afterwards they are translated out of this first Prison where they had little or no motion into another where they enjoy a more free and wandring motion as shall be more fully discoursed of in the following Chapters The third thing that flows from this Principle is That these same Atoms are the Cause of Motion and Life and that there is more of action and more of Life where these are in greater plenty and number provided the Corporeal Machine be disposed to motion For one of the principal Springs being broke the vital Atoms lose their action the greatest part of them exhale and withdraw themselves and others wandring about continue Vagabonds without any order or method So that it is necessary that the parts of a Compound Body should be disposed in some Order which when wanting the vital Atoms exert no motion but this order of parts would be to no purpose unless the vital Atoms were present to give them motion The same thing we observe in a Clock where an integrity and just disposition of the Wheels are required together with the force of a Spring to set all the Wheels in motion Although there be a great proportion and likeness between living Natural Bodies and these artificial Machines yet nevertheless there is a great difference between them for Atoms are Natural Springs and exist Originally in the seed out of which the Body is produced and they themselves are the Artificers of the Machines which give encrease to it and dispose the Parts of it in such manner that they may there exercise their motions and this is that great Artifice of Nature which operates by seeds produced from God which exceeds all that ever Art can devise CHAP. II. Of the Differences of Lives THe difference of Lives are only known by the difference of Vital Actions of which there are four kinds to wit the Mettallick Vegetative Sensitive and Rational Man the little World enjoys a Life under which all others are comprehended and chiefly in him we observe a vegetative Life as in Plants and a sensitive as in Brutes besides which two kinds of life He possesseth a third of his own which is a rational Life He is nourished that is and grows like Plants he is begotten of another he is sensible as an Animal and he speaketh and reasoneth as a Man all these different operations which we see in Man perswades us to consider him especially and to begin with the life of Plants which seems less considerable than the sensitive and rational and which comprehends under it their generation growth and nourishing which three are equally conspicuous in Man as in Plants though in a more noble and more eminent manner CHAP. III. Of the Vegetative Life common to Man and Plants THe Life of Plants appears from their growth which supposeth Nutrition and both these suppose a Birth and this implies a Generation For whatsoever grows in a vital manner and by Nature is nourished so likewise whatsoever is nourished hath a birth and every thing that is born is begotten We will therefore begin to speak of Man's generation and of the first forming of him The Generation we here speak of is the production of a thing out of Seed under this generation are comprehended Conception and Birth as Separation and Death are included in the Corruption of things This is that which is not found in the Works of Nature whose conception is made in the mind of the Artificer and its Formation depends upon his hand but all that is external to the work which may be afterwards broken and divided when in the mean time it cannot be said that we take away Life from it or bring Death upon it So that whatsoever is Begotten to speak properly Lives and whatsoever lives is produced out of Seed Now Seeds are created from the beginning and by the Author of Nature ingrafted into every Plant and kind of Tree bearing fruitful Seed So we see that there is a perpetual propagation and encrease of individuals in every Species in the Earth as well as in the Waters and in the Air. All and the only difficulty remains in explaining the Nature of this Seed and the manner of its propagation These two are Mysteries in Nature which seem to surpass all humane reason Nevertheless I will give you my meditations of them And first of all I suppose we may consider Seed in general and as it is to be found as we have said in Mettals Plants Animals and Man. For after this manner being looked upon in general it is nothing else but a Medium disposed by God to the propagation of these four several kinds in the World so that one Substance as to its kind produces its like in the same kind as Mettal is produced from Mettal and a Plant from another Plant c. From whence appears the fanciful Folly of Chymists who strive to multiply Mettals without a Mettallick Seed and to produce Gold without its peculiar Seed For the same thing that in general Seed is in respect of the four named generals the same in special is Seed in respect of the individuals which are produced of it For indeed to produce Plants the Seed is only to be sought for in the vegetable Kingdom So in like manner to produce Corn Seed is required that is a grain of Corn to produce an Apple there is need of the kernel of an Apple or at least a Sien of it which contains in it part of the Spirits and seminal Corpuscles which insinuate themselves into the wild Stock of the Tree in which they are ingraffed or inoculated and produce the same effect that a grain does which is thrown into Earth fit to receive it This is that vegetative Seed which we here speak of and in this regard we consider Man as he is partaker of the life of this Species and begotten out of Seed Nevertheless we are to distinguish the two substances in Man viz. the material part which is his Body and his spiritual part which is his Soul Created by God whereas the other is begotten So that we here speak of Man onely as he is a material Compound without medling with his Soul which is immortal These things being supposed I turn me to the two difficulties which I have obliged my self to explain and I design them a peculiar Chapter CHAP IV. Of the Nature of Seeds and of their Propagation THe Learned Fernelius affirms that Seeds contain an Astral and Coelestial Spirit but Galen that they contain something Divine These great Wits have spoken most wisely and have considered the seminal Spirit as a thing surpassing the Capacity of our Spirits
the Eyes are of that Figure that they cannot be placed elsewhere without a violent concussion of these mutually self impelling Atoms and these concussions are sometimes the cause why when the Women are hurt the Child is not at all formed and that by reason of the sole inordinate motion of one Corpuscle which either does not or being hindred by others which cause this motion cannot find a place due to its Figure It is plain therefore that seminal Corpuscles have the Figure of that part from whence they are derived and the whole humane Body is no otherwise shut up in a small part of Matter than an whole Oak in an Acorn and an Apple in a Kernel The example brought by me above concerning the divers kinds of Salt dissolved in water which in evaporating part asunder from each other and each possesseth his place not without a difference of Figures will give some light to this my Doctrine CHAP. V. Of Nutrition which Plants and Brute Beasts have common with Man. NUtrition is a vital action and so proper to Living Creatures that as there is nothing nourished that is not Living so there is no Living thing that is not nourished All the difficulty lies in the manner of Nutrition for no Man doubts but Animals and Plants at the beginning of their existence are nourished and grow which could not be without the addition of new Matter which is changed into the substance of the thing Living This addition of Matter takes in its attraction preparation digestion and its distribution through all the Parts of the Body nourished These opperations appear in Plants wherein it is amiss to attribute that to Nutritive Attractive Digestive and Distributive Qualities which may be explicated by the motion of the Atoms or seminal Corpuscles contained in the Seed But because Nutrition is much more conspicuous in Living Creatures and especially in Man it will be necessary to explain the Reason how that is performed in him in the first State after Conception and afterwards when the Organs are formed For there is need of Aliment that the Organs which are just formed and tenderer then to be sufficient to undergo their Operations may grow and be encreased So that at the very moment he begins to live there is a necessity that he should be nourished CHAP. VI. How and with what Aliment an Embryo is nourished 'till the time of his Birth THe first thing that is done after the laying together of the parts of the Embryo and the disposition of its Organs is the infusion of the Rational Soul which God in one and the same moment Creates and gives to this little Body as its Lodging Forty or sometimes more days after its Conception what is done before the infusion of this Soul to speak properly is nothing else but a disposition of the Organs to receive it This admirable Structure begins from the Heart Head Bones and other particular Fundamentals and when it is already compleated and the Soul infused the seminal Atoms Presidents of the formation of the Body persevere in performing their works taking as Companions of their Office these Particles of the Mothers Blood which may serve to nourish the Infant being sensibly solicitous for its increase 'till the time of its Nativity Yet nevertheless it is very difficult throughly to declare the true Reason of the Nutrition and Life of the Infant for seven or eight Months together Gassendus recounts three Opinions of the Antients concerning this thing the first is of Alcmaeon in Plutarch affirming the Infant to be nourished by all parts of the Body drawing in by the help of the Pores a necessary Aliment The second Opinion is by the same Plutarch attributed to Democritus this Philosopher teaches that the Infant is nourished in the Mothers Womb in the same manner as it is nourished when born to wit by the Mouth and this is the Cause he says why the newly born seek the Breast with open Mouth The third is Aristotle's Galen's and many others who conclude that the Infant takes no nourishment in the Womb but by the Umbilical Veins which taking their Original from the bottom of the Matrix insinuate themselves into the middle of the Abdomen or Belly where being collected into one Trunk they lead on the Mothers Blood into the hollow part of the Liver where part of it is carried into a Branch of Vena-Cava and part into a Branch of the Vena-Porta and the two Arteries which accompany the Umbilical Veins having passed the Liver each of them apart go to the two Branches of the Aorta or great Artery and carry the Arterial Blood which they bring thither that it may all be distributed through the whole Body of the Infant and changed into a substance fit for its Nutrition This Opinion is confirmed by the refutation of the two former For the first is false For if the Infant was like a Sponge it would not be nourished but swelled by the Water or serous humour in which it swims and which is contained in the Amnion The second Opinion is not probable For the Infants head is placed betwixt both knees nor can it suck the Caruncles which are covered with a Skin as is supposed unless at one and the same time it should attract the water wherein it lies hid or penetrate the Membrane in which it is involved The third Opinion standing firm which I believe rests upon a better foundation nor does the Infants Stomach generate Chyle nor its Liver Blood the Mothers Blood subministring all those things And from hence it is that a Woman with Child communicates to the fruit of her Womb the purity or impurity of her Blood her good or ill nourishment as also her Health and Diseases and these Diseases are hereditary not but that there are some which proceed from the Fathers whose impure Blood licentious living ill nourishment and frequent excesses afford matter to these evils Besides we may say that the Infant in the Mothers Womb does neither live nor breath but by the Mouth Heart and Lungs of the Mother from whence it comes to pass that the Infant for the most part follows the Mothers affections and inclinations and seeing that in the state wherein it is in the Womb it is tyed to its Mother in so strict a bond of Union it is impossible that she alone should be feaverish nor that the big-bellied Woman should dye the Child remaining alive and healthful CHAP. VII How Man is Nourished after he is Born. AMan Born hath need of Nourishment now nothing can nourish him which hath not some Spirit of Life So Roots Plants Corn Pulse Flesh serve to the nourishing of a Man and all this business is performed by the benefit of Atoms and vital Corpuscles passing from one Compound Body to another This Nutrition is necessary to encrease the substance of the born Infant and so there is need of a new Compound Body to serve it for Aliment And this Compound Body must of
Muscles of the Breast The Pulse is nothing else but a percussion of the Arteries upon the variety of which the difference of Pulses depends The Cause of the Pulse according to Aristotle is the Natural heat of the Heart according to Galen it is the moving faculty according to Harvey this motion of the Heart and Pulse of the Arteries depends upon the circulation of the Blood which we will examine in the next Chapter Breathing comprehends two actions Inspiration and Respiration by the action of the first the Lungs receive the external Air and by the help of the last they drive it out The first is made by a dilatation of the Lungs and Breast as also by the motion of the Diaphragme by which the Lungs are opened like a pair of Bellows and are by that means filled with Air the second is made by a pressing downwards of the Diaphragme by which the Lungs are unlocked and the Air driven forth Breathing conduces to the tempering the heat of the Heart and to the exciting and preserving Natural heat besides it conduceth to the forming the Voice to perceiving Smells to expelling Excrements and dissipating the fumes of the Blood and lastly to produce vital Spirits in promoting their motion by which it happens that we dye when breathing ceaseth or when we take our last Breath CHAP. XVII Of the Motion of the Heart THat I may rightly explain the motion of the Heart I suppose it is moved by two different motions the first of which is Natural the second against Nature That resembles the motion of Machines and Clocks which are moved by help of Strings and Wheels So the Heart is the principal and chief Wheel of this animated Machine and moves and drives on all the others and takes its motion from the weight and impression of certain Fiery and Coelestial Atoms which like the Silk-Worm are shut up in the Seed and its covering and which give motion to it until they flye away from it which slight of the Atoms Death follows and an end of motion The Authors of the circulation of the Blood deduce the motion of the Heart from the Bloods entring into it saying that the Heart is opened by the motion commonly called Diastole the Blood entring into the Heart and that by the motion commonly called Systole the Blood returns back and this returning is the Cause of those two motions but it is more reasonable to say that the motion of the Heart hath its Principle in its self for it is Vital and the passing through of the Blood is rather an effect than a Cause of this motion for the Heart opens it self before the Blood enters in nor does the Blood go out but as it is driven by the opened Heart The second motion of the Heart is accidental and against Nature and proceeds from the intemperies of the Blood that passeth through the Heart and which impresseth this febrile motion whether as being more hot and subtile than it should be or having certain foreign Corpuscles mixed with it or being too thick and viscous or else offending in quantity it overwhelms the Heart and hereupon depends the difference of motions contrary to Nature as also the difference of Pulses and Feavers from hence proceeds the palpitation of the Heart intermitting Pulses Convulsions Suffocations and sudden Death And it is commonly said that the Life is in the Blood nor does any thing hinder why we should not say that Death is in it too when it is corrupted or very sharp and corroding or unfit for motion and containing such like Bodies as lie hid in Venoms and Narcoticks The motion which is observed in the Hearts of Animals taken out of their Bodies as for Example that of a Viper which continues a long while does not disanul Circulation but only lets us see that Circulation is not the Cause of the Natural motion of the Heart and if you stretch it never so far it is only its condition which makes it continue and keeps the same in its Natural state Whatsoever we say concerning the Heart and its motions does not make up that Idea which we conceive in our mind nor does it satisfie the mind of the Reader who expects we should explain from whence this motion of the Heart while it is in its natural state proceeds and what is the Cause of its immoderate motions That I may therefore satisfie the Reader I Affirm the Natural Motion of the Heart to be in the motion of the Vital Spirits shut up in the central Vacuum of the Heart where they are detained by little Membranes made firm by the interweaving of Fibres and of thin threads so that they cannot escape out since the Pores of these membranes have a Figure opposite to the Pores of those Spirits or Vital Atoms And seeing that Atoms enjoy an actual motion and which can no more be separated from their Essence than Intelligence from an Angel or separated Soul or the Inclination from the Will it follows that they are always in motion and by their motions by turns dilate the Heart This Doctrine supposes what has been said of Vital Spirits being as it were the internal Principles of Life and Motion as also of the essential and proper motion of Atoms and of Bodies compounded of Atoms but it is convenient that we remember that we have said that motion is Natural to Atoms and that God who hath created them essentially moveable preserves their motion and moveable Nature in the same action that he Created them Besides it may be convenient to remember that there are such a sort of Atoms which may be detained and constitute the parts of a Compound Body and others which are not Naturally such yet may be shut up such as those are which we have said are shut up in the central Vacuum of the Heart of Living Creatures And these indeed are shut up by the decree of the Creator and the determination of the seminal covering The Comparison of an Angel and the Rational Soul seems to contribute much to the illustrating this Doctrine An Angel is a certain indivisible spiritual thing and an Intelligence free from Matter and the Rational Soul is no less a certain indivisible Spiritual thing endowed with Understanding and Will as an Angel yet they differ in this that theSoul is consined or as being a part of the Compound can be consined by a material Body whereas an Angel neither is nor can be confined which notwithstanding does not hinder but that it may be shut up into a Body as it were an assisting Form yet it hath not any respect to an internal and substantial Form. Besides I look upon an Angel and consider it under the notion of Atoms naturally free and the Rational Soul under the notion of those which are subject to confinement It is true that a Rational Soul going out of this Dungeon or Physical Prison by reason of the Corruption of the Body which permits it a free exit is
very well known that he that puts on a Garment or touches it leaves upon it his Scent that is Corpuscles which proceed from his Body and which constitute part of it and by the help of these Corpuscles a Dog is able to know his Masters Handkerchief Hat or Garment from ten thousand others This being supposed if the Dead Man's Garment or Gloak be put into a Press or Chest first and for some days when the Body that is Buried begins to putrifie there will be a considerable noise and disturbance in the Press or Chest enough to frighten Children and other folks too and the Corpuscles of the dead Body being attracted by those that are going away by their motion make this noise among the Cloaths And whereas this attraction is made in a streight Line and these Corpuscles cannot pass through the Bords but obliquely the Wood suffering violence makes a noise as if it were crackt Any one may trye this and know whether this Experiment made by others be true or no I see no reason to doubt of it From hence appears that invisible Bond of the Parts with the Body from whence they did proceed A third Experiment may be made which will serve to the illustrating this Subject Take a piece of Veal or any other Flesh from the Shambles and with it rub the Warts of any ones Face or Hands then afterwards fling it upon the Dunghil or Bury it and as that putrifies the Warts will fall off which denotes that the Corpuscles of Flesh returning to their whole or greater part and being violently attracted do in the same manner attract the Warts and make them go away which some Learned Men say they have Experienced We may admire in all these things the Providence of God who hath Created Atoms and out of them hath compounded the Universe wherein we find so great a number of wonderful things which are the subject of our admiration and convince our Ignorance CHAP. XXII Of the Death of Brutes Plants and Mettals SEeing that Man dyes other Animals cannot escape Death let us see wherein it consists The Followers of Aristotle are very much puzzled in explaining the Death of a Dog for when it is destitute of all Sense and Motion it is dead without doubt yet in the mean time it hath all its parts and Organs What therefore happens to this Animal It s Soul is separated from its Body say they and the Spirit of Life is not in him they do the Beast much honour who speak thus in his Favour But what becomes of this Soul Is it corrupted or annihilated or does it subsist apart in some other place or is it taken into some other Body No by no means say they it is not it is destroyed and that 's sufficient So it is sufficient to People who don 't seek after the Truth For if this Soul be a substance as they say it is a material one it is impossible but it must go into some other thing or else be reduced into nothing It is reduced into nothing say they therefore it is annihilated therefore it is Created and made out of nothing which is Ridiculous and unbecoming a Christian Philosopher It is true this Opinion is very common in the Schools but this Errour is detected and they who are wiser than others say with us that the Spirits of Life or Corpuscles of Light being altogether dissipated or hindred in their motion do withdraw and return to their Original and Copulate with others which are in the Air so dyes a Dog without the loss of that which God made the Parts are separated the Spirits seek the Air the Body the Earth Plants dye like other Living Creatures but their Death very much differs from the Death of Animals for as much as their Organical Parts do not appear so as they do in Animals nor does a Plant dye so easily as an Animal For a Plant is not dead so soon as it is pulled out of the ground its Life continues to the extream dryness or evaporation of the Radical moisture which contains all the Spirits of Life and though the Plant be calcined or burnt to Ashes part of the Spirits will remain in those Ashes for the Lixivium that is made or the Salt that is extracted gives all the Savour of the Plant and where that Lixivium is congealed by the Cold of the Night the Figure of the burnt Plant will appear in the very Ice But what is more to be observed is that a Plant dryed in a Kilne and put into a particular Water whose Virtue is Universal receives its pristine Greenness Leaves and Flowers without doubt in this dryed Plant some Vital Spirits were shut up which are relaxed by the Spirits of this Water or the Vital Spirits exhaling give way to the Spirits of the Water we speak of to take their places This Water is endued with Vital Spirits which can fill the place of those that exhale in us and with this sole Remedy Life may be prolonged and the losses of ruined Old-Age be repaired by filling up the Vacuities of the radical moisture which is dissipated But you will say where is this Water it is to be found in Light according to our Principles and certainly no where else This Water is the true Elixir-Vitae and the Universal Medicine of the Antients and it is meet that we use it to the preservation of the most Sacred Persons Mettals have a more abstruse Life than Plants nor is their Death more conspicuous Their Life consists in a certain disposition of Parts which permits a free motion to the Atoms of Life and Light. This is the State of Mettals in their Mines and when they are melted this Liberty is lost by the intervention of the Atoms of Fire and when after melting they grow cold they may be called Dead for they are deprived of motion nor do they perform any action Gold melted when it is grown cold is dead it Lived in the Mine it is dying whilst it is melting and it is dead when cast into Ingots In vain therefore do the Chymists seek for the Living among the Dead Common Gold is dead and good for nothing but to make Money of but if any one can dissolve this Body and bring the Dead to Life again by the benefit of that resuscitative Water which we spoke of before he may prepare a Medicine profitable to humane and Mettalick Bodies It is said before that Stones want Life But this I meant that they not a Life so notorious as Mettals whose Life hitherto is yet obscure enough for I have Learnt being convinced by Experience that the greatest part of Stones are multiplied and encrease according to all their dimensions and that Sand is turned into Shells And this very thing is the Cause that I conclude Light to be the Spirit of Life that by the benefit of it all things Live the very Stones also take their Life from hence Seeds owe all their Vigour to Light and seeing that Light is woven out of thin threads of Gold all things therefore Live by the Spirit of Gold. But the Soul of Man is Spiritual and a Ray of Divine Light and owes its Life to God and his Word as also it is an Immortal Substance as we shall say in the next and last Chpater
