Part 3

I have chosen, in the first place, the Work of that famous Philosopher _Hobbs_ called _Leviathan_, wherein I find he sayes,[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 out-side 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

_Madam_,

Your Authours opinion is,[1] 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; 'Tis 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. 'Tis true, 'tis 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,[1] _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 Authour 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,

_MADAM,_

Your Authours opinion, concerning Dreams,[1] 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 Gold, 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,

Madam,
