Kant's metaphysics, which says that the absolute whole of magnitude-the world-whole-has nothing to do with any possible experience, presses him to think of a thing in itself, which is merely intelligible. The difficulty is related to the issue of the absolute totality of series of conditions in connection with the issue of the absolute magnitude of the series in the world of sense, which looms as the antinomy of pure reason in the system of cosmological ideas. Since pure reason has no other aim than the absolute totality of synthesis on the side of conditions, we have to take steps in order to solve this problem, namely the absolute totality of synthesis on the side of conditions in conjunction with the absolute magnitude of the series in the world of sense, in such a way that we can comprehend transcendental aesthetics and the world-whole through empirical intuition and synthesis in accordance with experience or possible experience.
