XXIII.

_MADAM,_

I perceive by your last, that you cannot well apprehend my meaning,

when I say that the print or figure of a Body Printed or Carved, is

not made by the motions of the body Printing or Carving it, but by the

motions of the body or substance Printed or Carved; for say you, Doth

a piece of Wood carve it self, or a black Patch of a Lady cut its own

figure by its own motions? Before I answer you, _Madam_, give me leave

to ask you this question, whether it be the motion of the hand, or the

Instrument, or both, that print or carve such or such a body? Perchance

you will say, that the motion of the hand moves the Instrument, and the

Instrument moves the Wood which is to be carved: Then I ask, whether

the motion that moves the Instrument, be the Instruments, or the Hands?

Perchance you will say the Hands; but I answer, how can it be the Hands

motion, if it be in the Instrument? You will say, perhaps, the motion

of the hand is transferred out of the hand into the instrument, and so

from the instrument into the carved figure; but give me leave to ask

you, was this motion of the hand, that was transferred, Corporeal or

Incorporeal? If you say, Corporeal, then the hand must become less and

weak, but if Incorporeal, I ask you, how a bodiless motion can have

force and strength to carve and cut? But put an Impossible proposition,

as that there is an Immaterial motion, and that this Incorporeal motion

could be transferred out of one body into another; then I ask you, when

the hand and instrument cease to move, what is become of the motion?

Perhaps you will say, the motion perishes or is annihilated, and when

the hand and the instrument do move again, to the carving or cutting of

the figure, then a new Incorporeal Motion is created; Truly then there

will be a perpetual creation and annihilation of Incorporeal motions,

that is, of that which naturally is nothing; for an Incorporeal being

is as much as a natural No-thing, for Natural reason cannot know nor

have naturally any perception or Idea of an Incorporeal being: besides,

if the motion be Incorporeal, then it must needs be a supernatural

Spirit, for there is not any thing else Immaterial but they, and then

it will be either an Angel or a Devil, or the Immortal Soul of man; but

if you say it is the supernatural Soul, truly I cannot be perswaded

that the supernatural Soul should not have any other imployment then

to carve or cut prints, or figures, or move in the hands, or heels,

or legs, or arms of a Man; for other animals have the same kind of

Motions, and then they might have a Supernatural Soul as well as Man,

which moves in them. But if you say, that these transferrable motions

are material, then every action whereby the hand moves to the making

or moving of some other body, would lessen the number of the motions

in the hand, and weaken it, so that in the writing of one letter,

the hand would not be able to write a second letter, at least not

a third. But I pray, _Madam_, consider rationally, that though the

Artificer or Workman be the occasion of the motions of the carved

body, yet the motions of the body that is carved, are they which put

themselves into such or such a figure, or give themselves such or such

a print as the Artificer intended; for a Watch, although the Artist

or Watch-maker be the occasional cause that the Watch moves in such

or such an artificial figure, as the figure of a Watch, yet it is the

Watches own motion by which it moves; for when you carry the Watch

about you, certainly the Watch-makers hand is not then with it as to

move it; or if the motion of the Watch-makers hand be transferred into

the Watch, then certainly the Watch-maker cannot make another Watch,

unless there be a new creation of new motions made in his hands; so

that God and Nature would be as much troubled and concerned in the

making of Watches, as in the making of a new World; for God created

this World in six days, and rested the seventh day, but this would be a

perpetual Creation; Wherefore I say that some things may be Occasional

causes of other things, but not the Prime or Principal causes; and this

distinction is very well to be considered, for there are no frequenter

mistakes then to confound these two different causes, which make so

many confusions in natural Philosophy; and this is the Opinion of,

Madam,

_Your Faithful Friend_

_and Servant._
