[*Footnote; Space and time, and all portions thereof, are intuitions; consequently are, with a manifold for their content, single representations. (1) The cause and effect must be contiguous in space and time. But as sensuous intuition is a peculiar subjective condition, which is a priori at the foundation of all perception, and the form of which is primitive, the form must be given per se, and so far from matter (or the things themselves which appear) lying at the foundation of experience (as we must conclude, if we judge by mere conceptions), the very possibility of itself presupposes, on the contrary, a given formal intuition (space and time). As space is not a composite of substances (and not even of real accidents), if I abstract all composition therein--nothing, not even a point, remains; for a point is possible only as the limit of a space--consequently of a composite. If, then, we suppose an object of a non-sensuous intuition to be given we can in that case represent it by all those predicates which are implied in the presupposition that nothing appertaining to sensuous intuition belongs to it; for example, that it is not extended, or in space; that its duration is not time; that in it no change (the effect of the determinations in time) is to be met with, and so on. Thus much only can we say; "The image is a product of the empirical faculty of the productive imagination--the schema of sensuous conceptions (of figures in space, for example) is a product, and, as it were, a monogram of the pure imagination a priori, whereby and according to which images first become possible, which, however, can be connected with the conception only mediately by means of the schema which they indicate, and are in themselves never fully adequate to it." On the other hand, the schema of a pure conception of the understanding is something that cannot be reduced into any image--it is nothing else than the pure synthesis expressed by the category, conformably, to a rule of unity according to conceptions. Thus the mere form of external sensuous intuition, namely, space, affords us, per se, no cognition; it merely contributes the manifold in a priori intuition to a possible cognition.
