a Supernatural something but a Vacnum is a Pure nothing both Naturally and Supernaturally and God forbid I should be so irreligious as to compare Spirits and consequently God who is an Infinite Spirit to a Vacuum for God is All-fulfilling and an Infinite Fulness and Perfection though not a Corporeal or Material yet a Supernatural Spiritual and Incomprehensible fulness when as Vacuum although it is a corporeal word yet in effect or reality is nothing and expresses a want or imperfection which cannot be said of any supernatural Creature much less of God 20. Of Colours ALthough the sensitive perception doth pattern out the exterior figure of Colours as easily as of any other object yet all perceptions of Colours are not made by Patterning for as there are many perceptions which take no patterns from outward objects so there are also perceptions of Colours which never were presented to our sensitive organs Neither is any perception made by exterior objects but by interior corporeal figurative motions for the object doth not print or act any way upon the eye but it is the sensitive motions in the eye which pattern out the figure of the object and it is to be observed that as the parts of some bodies do consist of several different figures which the learned call Heterogeneous one figure being included within another and some again their parts are but of one kind of figure which they call Homogeneous bodies as for example Water so it may be with Colours for some their parts may be quite thorow of one colour and others again may be of several colours and indeed most Creatures as they have different parts so those different parts have also different colours and as those parts do alter so do their colours For example a Man that is in good health looks of a sanguine complexion but being troubled with the Yellow or black Jaundies his complexion is of the colour of the humor either black or yellow yet it doth not proceed always from the over-flowing of the humor towards the exterior parts for many times when the humor is obstructed it will cause the same effect but then the corporeal motions in the extream parts alter by way of Imitation or Metamorphosing as from a sanguine colour into the colour of the predominant humor Wherefore it is no more wonder to see colours change in the tempering of Steel as some are pleased to alledg this experiment then to see Steel change and rechange its temper from being hard to soft from tough to brittle c. which changes prove that colours are material as well as steel so that the alteration of the corporeal parts is the alteration of the corporeal figures of colours They also prove that Light is not essential to colours for although some colours are made by several Reflexions Refractions and Positions of Light yet Light is not the true and natural cause of all colours but those colours that are made by light are most inconstant momentany and alterable by reason light and its effects are very changeable Neither are colours made by a bare motion for there is no such thing as a bare or immaterial Motion in Nature but both Light and Colours are made by the corporeal figurative motions of Nature and according to the various changes of those Motions there are also various and different Lights and Colours and the perception of light and Colours is made and dissolved by the sensitive figurative motions in the optick sensorium without the exchange of exterior objects but as the slackest loosest or rarest parts are of least solid or composed corporeal figures so are they most apt to change and rechange upon the least disorder as may well be observed in colours raised by Passions as fear anger or the like which will change not onely the complexion and countenance but the very features will have some alteration for a short time and many times the whole body will be so altered as not to be rightly composed again for a good while nay often there follows a total dissolution of the whole figure which we call death And at all this we need not wonder if we do but consider that Nature is full of sense and reason that is of sensitive and rational perception which is the cause that oftentimes the disturbance of one part causes all other parts of a composed figure to take an alarum for as we may observe it is so in all other composed bodies even in those composed by Art as for example in the Politick body of a Common-wealth one Traytor is apt to cause all the Kingdom to take armes and although every member knows not particularly of the Traytor and of the circumstances of his crime yet every member if regular knows its particular duty which causes a general agreement to assist each other and as it is with a Common-wealth so it is also with an animal body for if there be factions amongst the parts of an animal body then straight there arises a Civil War Wherefore to return to Colours a sudden change of Colours may cause no wonder by reason there is oftentimes in Nature a sudden change of parts that is an alteration of figures in the same parts Neither is it more to be admired that one colour should be within another then one figurative part is within another for colours are figurative parts and as there are several Creatures so there are also several Colours for the Colour of a Creature is as well corporeal as the Creature it self and to express my self as clearly as I can Colour is as much a body as Place and Magnitude which are but one thing with body wherefore when the body or any corporeal part varies whether solid or rare Place Magnitude Colour and the like must of necessity change or vary also which change is no annihilation or perishing for as no particle of Matter can be lost in Nature nor no particular motion so neither can Colour and therefore the opinion of those who say That when Flax or Silk is divided into very small threads or fine parts those parts lose their colours and being twisted regain their colours seems not conformable to Truth for the division of their parts doth not destroy their colours nor the composing of those parts regain them but they being divided into such small and fine parts it makes their colours which are the finest of their exterior parts not to be subject to our optick perception for what is very small or rare is not subject to the humane optick sense wherefore there are these following conditions required to the optick perception of an exterior object First The object must not be too subtil rare or little but of a certain degree of magnitude Next It must not be too far distant or without the reach of our sight then the medium must not be obstructed so as to hinder our perception And lastly our optick sensorium must be perfect and the sensitive motions regular of
digestion or expulsion and the actions of contraction from those of dilation so the actions of imitation or patterning are different from the voluntary actions vulgarly called Conceptions and all this to make an equal poise or ballance between the actions of Nature Also there is difference in the degrees of motions in swiftness slowness rarity density appetites passions youth age growth decay c. as also between several sorts of perceptions all which proves that Nature is composed of self-moving parts which are the cause of all her varieties But this is well to be observed said they that the Rational parts are the purest and consequently the most active parts of Nature and have the quickest actions wherefore to ballance them there must be a dull part of Matter which is the Inanimate or else a World would be made in an instant and every thing would be produced altered and dissolved on a sudden as they had mentioned before Well replied my later Thoughts if there be such oppositions between the parts of Nature then I pray inform us whether they be all equally and exactly poised and ballanced To which the former answered That though it was most certain that there was a poise and ballance of Natures corporeal actions yet no particular Creature was able to know the exactness of the proportion that is between them because they are infinite Then my later Thoughts desired to know whether Motion could be annihilated The former said no because Nature was Infinite and admitted of no addition nor diminution and consequently of no new Creation nor annihilation of any part of hers But said the later If Motion be an accident it may be annihilated The former answered They did not know what they meant by the word Accident The later said That an Accident was something in a body but nothing without a body If an Accident be something answered the former Then certainly it must be body for there is nothing but what is corporeal in Nature and if it be body then it cannot be nothing at no time but it must of necessity be something But it cannot subsist of and by it self replied my later Thoughts as a substance for although it hath its own being yet its being is to subsist in another body The former answered That if an Accident was nothing without a body or substance and yet something in a body then they desired to know how being nothing it could subsist in another body and be separated from another body for composition and division said they are attributes of a body since nothing can be composed or divided but what has parts and nothing has parts but what is corporeal or has a body and therefore if an accident can be in a body and be separated from a body it would be non-sense to call it nothing But then my later Thoughts asked that when a particular Motion ceased what became of it The former answered it was not annihilated but changed The later said How can motion be corporeal and yet one thing with body Certainly if body be material and motion too they must needs be two several substances The former answered That motion and body were not two several substances but motion and matter made one self-moving body and so was place colour figure c. all one and the same with body The later replied That a Man and his action were not one and the same but two different things The former answered That a Man and his actions were no more different then a man was different from himself for said they although a man may have many different actions yet were not that man existent the same actions would not be for though many men have the like actions yet they are not the same But then replied the later Place cannot be the same with body nor colour because a man may change his place and his colour and yet retain his body Truly said the former If Place be changed then Body must change also for wheresoever is Place there is Body and though it be a vulgar phrase That a man changes his place when he heremoves yet it is not a proper Philosophical expression for he removes onely from such parts to such parts so that it is a change or a division and composition of parts and not of place And as for colour though it changes yet that proves not that it is not a body or can be annihilated The truth is though Figure Motion Colour c. do change yet they remain still in Nature and it is impossible that Nature can give away or lose the least of her corporeal Attributes or Proprieties for Nature is infinite in power as well as in act we mean for acting naturally and therefore whatsoever is not in present act is in the power of Infinite Nature But said my later Thoughts if a body be divided into very minute parts as little as dust where is the colour then The Colour answered the former is divided as well as the body and though the parts thereof be not subject to our sensitive perception yet they have nevertheless their being for all things cannot be perceptible by our senses The later said That the Colour of a Man's face could change from pale to red and from red to pale and yet the substance of the face remain the same which proved that colour and substance was not the same The former answered That although the colour of a mans face did change without altering the substance thereof yet this proved no more that Colour was Immaterial then that Motion was Immaterial for a man may put his body into several postures and have several actions and yet without any change of the substance of his body for all actions do not necessarily import a change of the parts of a composed figure there being infinite sorts of actions We will leave Accidents said my later Thoughts and return to the Inanimate part of Matter and since you declare that all parts of Nature do worship and adore God you contradict your self in allowing an Inanimate degree of Matter by reason where there is no self-motion there can be no perception of God and consequently no Worship and Adoration The former answered That the knowledg of God did not consist in exterior perception for God said they being an Infinite Incomprehensible supernatural and Immaterial Essence void of all parts can no ways be subject to Perception Nevetheless although no part can have an exterior perception of the substance of God as it has of particular natural Creatures yet it has Conceptions of the Existence of God to wit that there is a God above Nature on which Nature depends and from whose Immutable and Eternal Decree it has its Eternal Being as God's Eternal Servant but what God is in his Essence neither Nature nor any of her parts or Creatures is able to conceive And therefore although the Inanimate part of Matter is not perceptive yet having an innate knowledg and life
Animal tell what perception a Vegetable or Mineral has We may perceive that the Air which is an Element doth pattern out sound for it is not done by reverberation as pressure and reaction by reason there will be in some places not onely two several Ecchoes of one sound but in some three or four but surely one sound cannot be in several distant places at one time Also a Looking-glass we see does pattern out the figure of an object but yet we cannot be certainly affirmed that either the Glass or the Air have the same perceptions which Animals have for although their patterns are alike yet their perceptions may be different As for example the picture of a Man may be like its original but yet who knows what perception it has for though it represents the exterior figure of an Animal yet it is not of the nature of an Animal and therefore although a man may perceive his picture yet he knows not what perception the picture has of him for we can but judg by our selves of the perceptions of our own kind that is of Animal kind and not of the perceptions of other Creatures for example I observe that the perception of my exterior senses is made by an easie way of patterning out exterior objects and so conclude of the rest of my own kind to wit that the perception of their exterior sensitive organs is made after the same manner or way nay I perceive that also some perceptions of several other sorts of Creatures are made by way of patterning as in the forementioned examples of the Air and Glass and in Infectious Diseases where several Creatures will be infected by one object which certainly is not by an immediate propagation on so many numerous parts proceeding from the object but by imitation of the perceiving parts but yet I cannot infer from thence that all perceptions in Nature are made by imitation or patterning for some may and some may not and although our rational perception being more subtil then the sensitive may perceive somewhat more and judg better of outward objects then the sensitive yet it cannot be infallibly assured that it is onely so and not otherwise for we see that some animals are produced out of Vegetables whose off-spring is not any ways like their producer which proves that not all actions of Nature are made by imitation or patterning In short our reason does observe that all perception in general whatsoever is made by corporeal figurative self-motion but it cannot perceive the particular figurative motions that make every perception and though some Learned are of opinion that all perceptions are made by pressure and reaction yet it is not probable to sense and reason for this being but one sort of action would not make such variety of perceptions in the infinite parts of Nature as we may perceive there are Whensoever I say that outward objects work or cause such or such effects in the body sentient I do not mean that the object is the onely immediate cause of the changes of those parts in the sentient body but that it is onely an external or occasional cause and that the effects in the sentient proceed from its own inherent natural motions which upon the perception of the exterior object cause such effects in the sentient as are either agreeable to the motions of the object and that by way of imitation which is called Sympathy or disagreeable which is call'd Antipathy When I say That the several senses of Animals pattern out the several proprieties of one object as for example the Tongue patterns out the taste the Nostrils the smell the Ears the noise the Eyes the exterior figure shape colour c. and do prove by this that they are different things dividable from each other and yet in other places do affirm that colour place figure quantity or magnitude c. are one and the same with body and inseparable from each other 't is no contradiction for to be dividable from such or such parts and to be dividable from Matter are several things Smell and Taste although they be material or corporeal and cannot be divided from Matter yet there is no necessity that all parts of Nature must be subject to smell or taste or that such parts must have such smells and such tastes for though Colour Place Taste Smell c. are material and cannot be without body yet may they be conceived by our sense and reason to be different and several figures parts or actions for as there is no such thing as single parts or single divisions in Nature but all compositions divisions changes and alterations are within the body of Nature and yet there is such a variety and difference of natural figures and actions that one figure is not another nor one action another so it is likewise with the mentioned proprieties or what you 'l call them which although they cannot be separated from body or matter yet they may be altered changed composed and divided with their parts several ways and be perceived as various and different actions of Nature as they are for as one body may have several different motions at one and the same time so it may also have several proprieties though not dividable from Matter for all that is in Nature is material nor can there be any such thing as Immaterial accidents qualities properties and the like yet discernable by their different actions and changeable by the self-moving power of Nature But mistake me not when I say they are several different figures parts or actions for my meaning is not as if body and they were different things separable from each other or as if Colour Place Figure Magnitude c. were several parts of matter for then it would follow that some parts could be without place some without figure some without colour c. which is impossible for could there be a single Atome yet that Atome would have Colour Place Figure Magnitude c. onely there would be no motion for want of Parts and consequently no Perception But my meaning is That the several properties of a Body as for example Tast Touch Smell Sound being perceived by the several senses of Animals to wit the Tast by the Tongue the Smell by the Nose and Colour and Figure by the Eye c. it proves that they are several corporeal actions for the Tast is not the Smell nor Smell the Sound nor Sound the Colour Nevertheless they are all proprieties of the same body and no more dividable from body then motion is from body or body from matter onely they are made according to the several compositions and divisions of parts And as for Colour Place Magnitude Figure c. as I said before could there be an Atome it would have Colour Place Figure and though parts be changed millions of ways yet they cannot lose Colour Place and Figure The truth is as there are no single finite parts in Nature so there
Besides many of their Writings are but parcels taken from the ancient but such Writers are like those unconscionable men in Civil Wars which endeavour to pull down the hereditary Mansions of Noble-men and Gentlemen to build a Cottage of their own for so do they pull down the learning of Ancient Authors to render themselves famous in composing Books of their own But though this Age does ruine Palaces to make Cottages Churches to make Conventicles and Universities to make private Colledges and endeavour not onely to wound but to kill and bury the Fame of such meritorious Persons as the Ancient were yet I hope God of his mercy will preserve State Church and Schools from ruine and destruction Nor do I think their weak works will be able to overcome the strong wits of the Ancient for setting aside some few of our Moderns all the rest are but like dead and withered leaves in comparison to lovely and lively Plants and as for Arts I am confident that where there is one good Art found in these latter ages there are two better old Arts lost both of the AEgyptians Grecians Romans and many other ancient Nations when I say lost I mean in relation to our knowledg not in Nature for nothing can be lost in Nature Truly the Art of Augury was far more beneficial then the lately invented Art of Micrography for I cannot perceive any great advantage this Art doth bring us Also the Ecclipse of the Sun and Moon was not found out by Telescopes nor the motions of the Loadstone nor the Art of the Card nor the Art of Guns and Gun-powder nor the Art of Printing and the like by Microscopes nay if it be true that Telescopes make appear the spots in the Sun and Moon or discover some new Stars what benefit is that to us Or if Microscopes do truly represent the exterior parts and superficies of some minute Creatures what advantages it our knowledg For unless they could discover their interior corporeal figurative motions and the obscure actions of Nature or the causes which make such or such Creatures I see no great benefit or advantage they yield to man Or if they discover how reflected light makes loose and superficial Colours such as no sooner percieved but are again dissolved what benefit is that to man For neither Painters nor Dyers can inclose and mix that Atomical dust and those reflections of light to serve them for any use Wherefore in my opinion it is both time and labour lost for the inspection of the exterior parts of Vegetables doth not give us any knowledg how to Sow Set Plant and Graft so that a Gardener or Husbandman will gain no advantage at all by this Art The inspection of a Bee through a Microscope will bring him no more Honey nor the inspection of a grain more Corn neither will the inspection of dusty Atomes and reflections of light teach Painters how to make and mix Colours although it may perhaps be an advantage to a decayed Ladies face by placing her self in such or such a reflection of Light where the dusty Atomes may hide her wrinkles The truth is most of these Arts are Fallacies rather then discoveries of Truth for Sense deludes more then it gives a true Information and an exterior inspection through an Optick glass is so deceiving that it cannot be relied upon Wherefore Regular Reason is the best guide to all Arts as I shall make it appear in this following Treatise It may be the World will judg it a fault in me that I oppose so many eminent and ingenious Writers but I do it not out of a contradicting or wrangling nature but out of an endeavour to find out truth or at least the probability of truth according to that proportion of sense and reason Nature has bestowed upon me for as I have heard my Noble Lord say that in the Art of Riding and Fencing there is but one Truth but many Falshoods and Fallacies So it may be said of Natural Philophy and Divinity for there is but one Fundamental Truth in each and I am as ambitious of finding out the truth of Nature as an honourable Dueller is of gaining fame and repute for as he will fight with none but an honourable and valiant opposite so am I resolved to argue with none but those which have the renown of being famous and subtil Philosophers and therefore as I have had the courage to argue heretofore with some famous and eminent Writers in Speculative Philosophy so have I taken upon me in this present work to make some reflections also upon some of our Modern Experimental and Dioptrical Writers They will perhaps think my self an inconsiderable opposite because I am not of their Sex and therefore strive to hit my Opinions with a side stroke rather covertly then openly and directly but if this should chance the impartial World I hope will grant me so much Justice as to consider my honesty and their fallacy and pass such a judgment as will declare them to be Patrons not onely to Truth but also to Justice and Equity for which Heaven will grant them their reward and time will record their noble and worthy Actions in the Register of Fame to be kept in everlasting Memory TO THE READER Curteous Reader I Do ingeniously confess that both for want of learning and reading Philosophical Authors I have not expressed my self in my Philosophical Works especially in my Philosophical and Physical Opinions so clearly and plainly as I might have done had I had the assistance of Art and the practice of reading other Authors But though my Conceptions seem not so perspicuous in the mentioned Book of Philosophical Opinions yet my Philosophical Letters and these present Observations will I hope render it more intelligible which I have writ not out of an ambitious humour to fill the World with useless Books but to explain and illustrate my own Opinions For what benefit would it be to me if I should put forth a work which by reason of its obscure and hard notious could not be understood especially it is knowil that Natural Philosophy is the hardest of all humane learning by reason it consists onely in Contemplation and to make the Philosophical Conceptions of ones mind known to others is more difffcult then to make them believe that if A. B. be equal to C. D. then E. F. is equal to A. B. because it is equal to C. D. But as for Learning that I am not versed in it no body I hope will blame me for it since it is sufficiently known that our Sex is not bread up to it as being not suffer'd to be instructed in Schools and Vniversities I will not say but many of our Sex may have as much wit and be capable of Learning as well as Men but since they want Instructions it is not possible they should attain to it for Learning is Artificial but Wit is Natural Wherefore when I began to read the Philosophical Works
which conditions if any be wanting there is either no perception at all or it is an imperfect perception for the perception of seeing an exterior object is nothing else but a patterning out of the figure of that same object by the sensitive figurative and perceptive motions but there are infinite parts that are beyond our humane perception and it would be but a folly for us to deny that which we cannot see or perceive and if the perceptive motions be not regular in our optick sense we may see different colours in one object nay the corporeal figurative motions in the eye may make several figurative colours even without the patterns of outward objects and as there are several colours so there are also several corporeal figurative motions that make several colours in several parts and the more solid the parts are the more fixt are their inherent natural colours But superficial colours are more various though not so various as they would be if made by dusty Atomes flying about as Flies in Sun-shine for if this opinion were true all colours and other Creatures would be composed or made by chance rather then by reason and chance being so ignorantly inconstant not any two parts would be of the like colour nor any kind or species would be preserved but Wise Nature although she be full of variety yet she is also full of reason which is knowledg for there is no part of Nature that has not sense and reason which is life and knowledg and if all the infinite parts have life and knowledg Infinite Nature cannot be a fool or insensible But mistake me not for I do not mean that her parts in particular are infinitely knowing but I say Infinite Nature hath an Infinite knowledg and by reason Nature is material she is divideable as well as composeable which is the cause that there is an obscurity in her Parts in particular but not in general that is in Nature her self nay if there were not an obscurity in the Particulars men would not endeavour to prove inherent and natural figures by superficial Phaenomena's But as for Colour some do mention the example of a blind man who could discover colours by touch and truly I cannot account it a wonder because colours are corporeal figurative motions and touch being a general sence may well perceive by experience which is gained by practice some Notions of other sensitive perceptions as for example a blind man may know by relation the several touches of Water Milk Broth Jelly Vinegar Vitriol c. as well as what is hot cold rare dense hard soft or the like and if he have but his touch hearing speaking and smelling perfectly he may express the several knowledges of his several senses by one particular sense or he may express one senses knowledg by another but if the senses be imperfect he cannot have a true knowledg of any object The same may be said of Colours for several Colours being made by several corporeal figurative motions may well be perceived by a general sense which is Touch I will not say that touch is the principle of all sensitive knowledg for then I should be of the opinion of those Experimental Philosophers which will have one principal motion or figure to be the cause of all Natural things but I onely say animal touch may have some Notion of the other animal senses by the help of rational perception all which proves that every part is sensible and every sense knowing not onely in particular but that one sense may have some general notion or knowledg of the rest for there are particular and general perceptions in sensitive and rational matter which is the cause both of the variety and order of Nature's Works and therefore it is not necessary that a black figure must be rough and a white figure smooth Neither are white and black the Ground-figures of Colours as some do conceive or as others do imagine blew and yellow for no particular figure can be a principle but they are all but effects and I think it is as great an error to believe Effects for Principles as to judg of the Interior Natures and Motions of Creatures by their Exterior Phaenomena or appearances which I observe in most of our modern Authors whereof some are for Incorporeal Motions others for Prime and Principal Figures others for First Matter others for the figures of dusty and insensible Atomes that move by chance when as neither Atomes Corpuscles or Particles nor Pores Light or the like can be the cause of fixt and natural colours for if it were so then there would be no stayed or solid colour insomuch as a Horse or any other Creature would be of more various colours then a Rain-bow but that several colours are of several figures was always and is still my opinion and that the change of colours proceeds from the alteration of their figures as I have more at large declared in my other Philosophical Works Indeed Art can no more force certain Atomes or Particles to meet and join to the making of such a figure as Art would have then it can make by a bare command Insensible Atomes to join into a Uniform World I do not say this as if there could not be Artificial Colours or any Artificial Effects in Nature but my meaning onely is that although Art can put several parts together or divide and disjoyn them yet it cannot make those parts move or work so as to alter their proper figures or interior natures or to be the cause of changing and altering their own or other parts any otherwise then they are by their Natures Neither do I say that no Colours are made by Light but I say onely that fixt colours are not made by Light and as for the opinion that white bodies reflect the Light outward and black bodies inward as some Authors do imagine I answer 'T is probable some bodies may do so but all white and black Colours are not made by such reflexions the truth is some conceive all Colours to be made by one sort of Motion like as some do believe that all sensation is made by pressure and reaction and all heat by parts tending outward and all cold by parts tending inward when as there are not onely several kinds of heat and cold as Animal Vegetable Mineral and Elemental heat and cold but several sorts in each kind and different particulars in each sort for there is a moist heat a dry heat a burning a dissolving a composing a dilating a contracting heat and many more The like for colds all which several kinds sorts and particulars are made by the several changes of the corporeal figurative Motions of Nature and not by Pressure and Reaction or by tending inward and outward And as there is so great a variety and difference amongst natural Creatures both in their Perceptions and interior natures so there are also varieties of their colours the natural colours of men being
