_MADAM,_

That Matter is uncapable of Sense, your _Author_ proves by the example

of dead Carcasses;[1] _For,_ says he, _Motion and Sense being really

one and the same thing, it must needs follow, that where there is

motion, there is also sense and perception; but on the contrary, there

is Reaction in dead Carcasses, and yet no Sense._ I answer shortly,

That it is no consequence, because there is no animal sense nor

exterior perceptible local motion in a dead Carcass, therefore there

is no sense at all in it; for though it has not animal sense, yet it

may nevertheless have sense according to the nature of that figure,

into which it did change from being an animal. Also he says, _If any

Matter have sense, it will follow, that upon reaction all shall have

the like; and that a Bell while it is ringing, and a Bow while it is

bent, and every Jack-in-a-box, that School-boys play with, shall be

living animals._ I answer, It is true, if reaction made sense; but

reaction doth not make sense, but sense makes reaction; and though the

Bell hath not an animal knowledg, yet it may have a mineral life and

knowledg, and the Bow, and the Jack-in-a-box a vegetable knowledg; for

the shape and form of the Bell, Bow, and Jack-in-a-box, is artificial;

nevertheless each in its own kind may have as much knowledg as an

animal in his kind; onely they are different according to the different

proprieties of their Figures: And who can prove the contrary that they

have not? For certainly Man cannot prove what he cannot know; but Mans

nature is so, that knowing but little of other Creatures, he presently

judges there is no more knowledg in Nature, then what Man, at least

Animals, have; and confines all sense onely to Animal sense, and all

knowledg to Animal knowledg. Again says your Author, _That Matter is

utterly uncapable of such operations as we find in our selves, and

that therefore there is something in us Immaterial or Incorporeal;

for we find in our selves that one and the same thing, both hears,

and sees, and tastes, and perceives all the variety of objects that

Nature manifests unto us._ I answer, That is the reason there is but

one matter, and that all natural perception is made by the animate

part of matter; but although there is but one matter in Nature, yet

there are several parts or degrees, and consequently several actions

of that onely matter, which causes such a variety of perceptions,

both sensitive and rational: the sensitive perception is made by the

sensitive corporeal motions, copying out the figures of forreign

objects in the sensitive organs of the sentient; and if those sensitive

motions do pattern out forreign objects in each sensitive organ alike

at one and the same time, then we hear, see, taste, touch and smell,

at one and the same time: But Thoughts and Passions, as Imagination,

Conception, Fancy, Memory, Love, Hate, Fear, Joy, and the like, are

made by the rational corporeal motions in their own degree of matter,

to wit, the rational. And thus all perception is made by one and the

same matter, through the variety of its actions or motions, making

various and several figures, both sensitive and rational. But all this

variety in sense and reason, or of sensitive and rational perceptions,

is not made by parts pressing upon parts, but by changing their own

parts of matter into several figures by the power of self-motion: For

example, I see a Man or Beast; that Man or Beast doth not touch my

eye, in the least, neither in it self, nor by pressing the adjoyning

parts: but the sensitive corporeal motions streight upon the sight of

the Man or Beast make the like figure in the sensitive organ, the Eye,

and in the eyes own substance or matter, as being in the eye as well

as the other degrees of matter, to wit, the rational and inanimate,

for they are all mixt together. But this is to be observed, That the

rational matter can and doth move in its own substance, as being the

purest and subtillest degree of matter; but the sensitive being not so

pure and subtil, moves always with the inanimate Matter, and so the

perceptive figures which the rational Matter, or rational corporeal

Motions make, are made in their own degree of Matter; but those figures

which the sensitive patterns out, are made in the organs or parts of

the sentient body proper to such or such a sense or perception: as in

an animal Creature, the perception of sight is made by the sensitive

corporeal motions in the Eye; the perception of hearing, in the Ear,

and so forth. As for what your _Author_ says, _That we cannot conceive

any portion of Matter, but is either hard or soft_; I answer, That

these are but effects of Matters actions, and so is rare, and dense,

and the like; but there are some Creatures which seem neither perfectly

rare, nor dense, nor hard, nor soft, but of mixt qualities; as for

example, Quicksilver seems rare, and yet is dense; soft, and yet is

hard; for though liquid Quicksilver is soft to our touch, and rare to

our sight, yet it is so dense and hard, as not to be readily dissolved

from its nature; and if there be such contraries and mixtures in

one particular creature made of self-moving Matter, what will there

not be in Matter it self, according to the old saying: _If the Man

such praise shall have; What the Master that keeps the knave?_ So if

a particular Creature hath such opposite qualities and mixtures of

corporeal motions, what will the Creator have which is self-moving

Matter? Wherefore it is impossible to affirm, that self-moving Matter

is either all rare, or all dense, or all hard, or all soft; because by

its self-moving power it can be either, or both, and so by the change

and variety of motion, there may be soft and rare Points, and hard and

sharp Points, hard and contracted Globes, and soft and rare Globes;

also there may be pressures of Parts without printing, and printing

without pressures. Concerning that part of Matter which is the _Common

Sensorium_, your _Author_ demands, _Whether some point of it receive

the whole Image of the object, or whether it be wholly received into

every point of it?_ I answer, first, That all sensitive Matter is not

in Points; Next, That not any single part can subsist of it self; and

then that one Part doth not receive all parts or any part into it self;

but that Parts by the power of self-motion can and do make several

figures of all sizes and sorts, and can Epitomize a great object into

a very little figure; for outward objects do not move the body, but

the sensitive and rational matter moves according to the figures of

outward objects: I do not say always, but most commonly; _But_, says

your Author, _How can so smal a Point receive the Images of so vast

or so various objects at once, without obliteration or confusion._

First, I answer, That, as I said before, sensitive Matter is not bound

up to a Point, nor to be a single self-subsisting Part. Next, as for

confusion, I say, that the sensitive matter makes no more confusion,

then an Engraver, when he engraves several figures in a small stone,

and a Painter draws several figures in a small compass; for a Carver

will cut out several figures in a Cherry-stone, and a Lady in a little

black Patch; and if gross and rude Art is able to do this, what may

not Ingenious and Wise Nature do? And as Nature is ingenious and

knowing in her self, so in her Parts, and her Parts in her; for neither

whole nor Parts are ignorant, but have a knowledg, each according to

the motion of its own Parts; for knowledg is in Motion, and Motion

in Matter; and the diversity and variety of motion is the diversity

and variety of knowledg, so that every particular figure and motion

hath its particular knowledg, as well as its proper and peculiar

parts; and as the parts join or divide, so doth knowledg, which many

times causes Arts to be lost and found, and memory and remembrance in

Particular Creatures: I do not say, they are utterly lost in nature,

but onely in respect to particular Creatures, by the dissolving and

dividing of their particular figures. For the rational matter, by

reason it moves onely in its own parts, it can change and rechange

into several figures without division of parts, which makes memory

and remembrance: But men not considering or believing there might

be such a degree of onely matter, namely rational, it has made them

erre in their judgments. Nevertheless there is a difference between

sensitive and rational parts and motions, and yet they are agreeable

most commonly in their actions, though not always. Also the rational

can make such figures as the sensitive cannot, by reason the rational

has a greater power and subtiler faculty in making variety, then the

sensitive; for the sensitive is bound to move with the inanimate, but

the rational moves onely in its own parts; for though the sensitive

and rational oftentimes cause each other to move, yet they are not of

one and the same degree of matter, nor have they the same motions.

And this rational Matter is the cause of all Notions, Conceptions,

Imaginations, Deliberation, Determination, Memory, and any thing else

that belongs to the Mind; for this matter is the mind of Nature, and

so being dividable, the mind of all Creatures, as the sensitive is the

life; and it can move, as I said, more subtilly, and more variously

then the sensitive, and make such figures as the sensitive cannot,

without outward examples and objects. But all diversity comes by

change of motion, and motions are as sympathetical and agreeing, as

antipathetical and disagreeing; And though Nature's artificial motions,

which are her Playing motions, are sometimes extravagant, yet in her

fundamental actions there is no extravagancy, as we may observe by her

exact rules in the various generations, the distinct kinds and sorts,

the several exact measures, times, proportions and motions of all her

Creatures, in all which her wisdom is well exprest, and in the variety

her wise pleasure: To which I leave her, and rest,

Madam,

_Your faithful Friend,_

_and Servant._
