To be sure, it appears that since a body has to be represented as a substance in space, it is to be distinguished from a space as far as the law of the divisibi jty of space is concerned; for one can in any case concede that the decomposition of the latter could never do away with all com position, since then every space, having nothing else that is self subsis tent, would cease to be (which is impossible); yet it does not seem to be compatible with the concept of a substance which is really supposed to be the subject of all composition, and has to remain in its elements even if its connection in space, by which it constitutes a body, were re moved that if all composition of matter were removed in thought, then nothing at all would remain.
