Th'other day I met with the Work of that Learned Author Dr. Ch. which treats of Natural Philosophy; and amongst the rest, in the Chapter of Place, I found that he blames Aristotle for saying, there are none but corporeal dimensions, Length, Breadth, and Depth in Nature, making besides these corporeal, other incorporeal dimensions which he attributes to Vacuum. Truly, Madam, an incorporeal dimension or extension, seems, in my opinion, a meer contradiction; for I cannot conceive how nothing can have a dimension or extension, having nothing to be extended or measured. His words are these: Imagine we therefore, that God should please to annihilate the whole stock or mass of Elements, and all concretions resulting therefrom, that is, all corporeal substances now contained within the ambit or concave of the lowest Heaven, or Lunar sphear; and having thus imagined, can we conceive that all the vast space or region circumscribed by the concave superfice of the Lunar sphere, would not remain the same in all its dimensions, after as before the reduction of all bodies included therein to nothing? To which, I answer: That, in my opinion, he makes Nature Supernatural; for although God's Power may make Vacuum, yet Nature cannot; for God's and Nature's Power are not to be compared, neither is God's invisible Power perceptible by Natures parts; but according to Natural Perception, it is impossible to conceive a Vacuum, for we cannot imagine a Vacuum, but we must think of a body, as your Author of the Circle of the Moon; neither could he think of space but from one side of the Circle to the other, so that in his mind he brings two sides together, and yet will have them distant; but the motions of his thoughts being subtiler and swifter then his senses, skip from side to side without touching the middle parts, like as a Squirrel from bough to bough, or an Ape from one table to another; without touching the ground, onely cutting the air. Next, he says, That an absolute Vacuum, is neither an Accident, nor a Body, nor yet Nothing, but Something, because it has a being; which opinion seems to me like that of the divine Soul; but I suppose Vacuum is not the divine Soul, nor the divine Soul, Vacuum; or else it could not be sensible of the blessed happiness in Heaven, or the Torments in Hell. Again he says, Let us screw our supposition one pin higher, and farther imagine, that God, after the annihilation of this vast machine, the Universe, should create another in all respects equal to this, and in the same part of space wherein this now consists: First, we must conceive, that as the spaces were immense before God created the world, so also must they eternally persist of infinite extent, if he shall please at any time to destroy it; next, that these immense spaces are absolutely immoveable. By this opinion, it seems, that Gods Power cannot so easily make or annihilate Vacuum, as a substance; because he believes it to be before all Matter, and to remain after all Matter, which is to be eternal; but I cannot conceive, why Matter, or fulness of body, should not as well be Infinite and Eternal, as his Conceived Vacuum; for if Vacuum can have an eternal and infinite being, why may not fulness of body, or Matter? But he calls Vacuum Immovable, which in my opinion is to make it a God; for God is onely Immoveable and Unalterable, and this is more Glorious then to be dependant upon God; wherefore to believe Matter to be Eternal, but yet dependent upon God, is a more humble opinion, then his opinion of Vacuum; for if Vacuum be not created, and shall not be annihilated, but is Uncreated, Immaterial, Immoveable, Infinite, and Eternal, it is a God; but if it be created, God being not a Creator of Nothing, nor an annihilator of Nothing, but of Something, he cannot be a Creator of Vacuum; for Vacuum is a pure Nothing. But leaving Nothing to those that can make something of it, I will add no more, but rest,
Madam,
Your faithful Friend
and Servant.

MADAM,
That Learned Author, of whom I made mention in my last, is pleased to say in his Chapter of Time, that Time is the Twin-brother to Space; but if Space be as much as Vacuum, then I say, they are Twin-nothings; for there can be no such thing as an empty or immaterial space, but that which man calls space, is onely a distance betwixt several corporeal parts, and time is onely the variation of corporeal motions; for were there no body, there could not be any space, and were there no corporeal motion, there could not be any time. As for Time, considered in General, it is nothing else but the corporeal motions in Nature, and Particular times are the Particular corporeal motions; but Duration is onely a continuance, or continued subsistence of the same parts, caused by the consistent motions of those parts; Neither are Time, Duration, Place, Space, Magnitude, &c. dependents upon corporeal motions, but they are all one and the same thing; Neither was Time before, nor can be after corporeal motion, for none can be without the other, being all one: And as for Eternity, it is one fixed instant, without a flux, or motion. Concerning his argument of Divisibility of Parts, my opinion is, That there is no Part in Nature Individable, no not that so small a part, which the Epicureans name an Atome; neither is Matter separable from Matter, nor Parts from Parts in General, but onely in Particulars; for though parts can be separated from parts, by self-motion, yet upon necessity they must joyn to parts, so as there can never be a single part by it self. But hereof, as also of Place, Space, Time, Motion, Figure, Magnitude, &c. I have sufficiently discoursed in my former Letters, as also in my Book of Philosophy; and as for my opinion of Atoms, their figures and motions, (if any such things there be) I will refer you to my Book of Poems, out of which give me leave to repeat these following lines, containing the ground of my opinion of Atomes:[1]
All Creatures, howsoe're they may be nam'd,
Are of long, square, flat, or sharp Atoms fram'd.
Thus several figures several tempers make,
But what is mixt, doth of the four partake.
The onely cause, why things do live and die,
'S according as the mixed Atomes lie.
Thus life, and death, and young, and old,
Are as the several Atoms hold:
Wit, understanding in the brain
Are as the several atomes reign:
And dispositions, good, or ill,
Are as the several atomes still;
And every Passion, which doth rise,
Is as each several atome lies.
Thus sickness, health, and peace, and war,
Are as the several atomes are.
If you desire to know more, you may read my mentioned Book of Poems whose first Edition was printed in the year, 1653. And so taking my leave of you, I rest,
