For they are not subordinated to each other as conditions of the possibility of each other; which, however, may be affirmed of spaces, the limits of which are never determined in themselves, but always by some other space. For example, if we take away by degrees from our conceptions of a body all that can be referred to mere sensuous experience--colour, hardness or softness, weight, even impenetrability--the body will then vanish; but the space which it occupied still remains, and this it is utterly impossible to annihilate in thought. For the rest, this formal reality of time and space leaves the validity of our empirical knowledge unshaken; for our certainty in that respect is equally firm, whether these forms necessarily inhere in the things themselves, or only in our intuitions of them. The mind, elevated by the vastness of its object, is still farther elevated by the difficulty of the conception; and being obliged every moment to renew its efforts in the transition from one part of time to another, feels a more vigorous and sublime disposition, than in a transition through the parts of space, where the ideas flow along with easiness and facility. Of time we cannot have any external intuition, any more than we can have an internal intuition of space. For as conditions of all existence in general, space and time must be conditions of the existence of the Supreme Being also. - If they adopt the second view of inherence, which is preferred by some metaphysical natural philosophers, and regard space and time as relations (contiguity in space or succession in time), abstracted from experience, though represented confusedly in this state of separation, they find themselves in that case necessitated to deny the validity of mathematical doctrines a priori in reference to real things (for example, in space)--at all events their apodeictic certainty.
