evaluation and critique of kant’s propositions

in the “critique of pure reason (kritik der reinen vernunft)” kant apply the ‘judgment’ as an entry to his philosophical system and according to which he offers quadra division of propositions and with analyzing of this propositions he try to reach his implications and results. so basic philosophical categories like possibility of metaphysics, causality, universality, necessity, explanation of natural science and so on, bases on this division of proposition. but if we prove that he was wrong in his initial steps and there are other modes for explanation of these categories (e.g. universality, necessity and etc), we could cancel the bases of many of his conceptions. in this article we chose another mode and show that his idea is controvertible. we clarify that all the propositions are a- posteriori.
