We cannot, even theoretically, split a solid into mere surfaces, a surface into mere lines, or a line into mere points.
Against such statements the plain man is not impelled to rise in rebellion, for he can see that there seems to be some ground for making them.

He can conceive of any particular material object as annihilated, and of the place which it occupied as standing empty; but he cannot go on and conceive of the annihilation of this bit of empty space.
