_intensively_, but acts finitely, _i.e. extensively_. Each individual and species is finite, but the number of all individuals is infinite, and infinite are the matter in which they consist and the space in which they move. Everywhere, therefore, limit and measure are only in the particular and the individual, which, compared with the universe, are nothing. [Sidenote: 6. Figure and body.] A further argument was derived from the necessity of figure in body and from the relation of body to space.[311] Every body is known to us as of a certain and definite figure, whereas infinite body would necessarily be unfigured. In this case, said Bruno, Aristotle is confounding body with space, although he elsewhere separates the two notions. That space is something other than the bodies which fill it, that it is more than limit or figure, is evident from the fact that always between any two corporeal surfaces, between any two atoms, there is space. Nor is space merely an accident of body, a special quality of it, as colour is, for example, for we cannot think of colour without a body in which it exists, and when the body is abstracted the colour goes also, whereas space may be thought of apart from body, and body, when removed does not take with it its space. Perhaps we should say that space is really the continuous ether or light which penetrates throughout the universe, and seems to fill space more continuously than wood, stone, or iron, in which there is an admixture of _vacuum_. Must all bodies be figured, then the figure of the infinite is the sphere. The dimensions of space coincide with those of body, and the definition given of body as tri-dimensional quantity applies also to space:--there cannot be any body which is not in place, nor can its dimensions exist without equal dimensions of the containing space.
