We cannot annihilate in thought one side of a door and leave the other side; we cannot rob a man of the outside of his hat and leave him the inside.

But we can conceive of a whole door as annihilated, and of a man as losing a whole hat.

May we or may we not conceive of space as a whole as nonexistent?
I do not say, be it observed, can we conceive of something as attacking and annihilating space?
Whatever space may be, we none of us think of it as a something that may be threatened and demolished.

I only say, may we not think of a system of things--not a world such as ours, of course, but still a system of things of some sort--in which space relations have no part?
May we not conceive such to be possible?
It should be remarked that space relations are by no means the only ones in which we think of things as existing.

We attribute to them time relations as well.
