Incogitative Being cannot produce a Cogitative Being.
If, then, there must be something eternal, let us see what sort of being it must be.

And to that it is very obvious to reason, that it must necessarily be a cogitative being.

For it is as impossible to conceive that ever bare incogitative matter should produce a thinking intelligent being, as that nothing should of itself produce matter.

Let us suppose any parcel of matter eternal, great or small, we shall find it, in itself, able to produce nothing.

For example: let us suppose the matter of the next pebble we meet with eternal, closely united, and the parts firmly at rest together; if there were no other being in the world, must it not eternally remain so, a dead inactive lump?
Is it possible to conceive it can add motion to itself, being purely matter, or produce anything?
Matter, then, by its own strength, cannot produce in itself so much as motion: the motion it has must also be from eternity, or else be produced, and added to matter by some other being more powerful than matter; matter, as is evident, having not power to produce motion in itself.
