KANT AND THE DISCIPLINE OF PURE REASON. THE SYNTHETICAL TRANSCENDENTAL PROPOSITIONS AND THEIR DEMONSTRATIONS

In the second chapter of Analytic of Principles, Grundsatze are exhibited as synthetic judgements of pure understanding. In the explanation of the possibility of synthetic judgements there is at stake a special delimitation guaranteed on "principles that could effect a necessary renunciation of the right to dogmatic assertion" (A 768 B 796). A renunciation that will be completely reached at the time that the transcendental logic of truth will be articulated in the whole of pure principles, without which any empirical judgement or scientific knowledge will lose its objective connection and thus its truthful content. This necessary attribute is expressed by the definition of the pure rules of understanding, that are not only the unities influencing every unification of manifold, but "are rather even the source of all truth". By examining and comparing the second chapter of An. of Pr. and the Discipline of pure reason, my purpose is to note the specific ostensive nature of the proofs of transcendental and synthetic propositions and to demonstrate why this character is really meaningful in order to be able to articulate the faculty of pure reason making experience possible.
