Abstract
The aim of this article assumes the following tasks: firstly, it trys to underline the importance of the historical-exegetical point of view with respect to the problem of the sources and reasons of the well-known changes operated by Kant in the second edition of Critique; secondly, it emphasizes an assumed systematic-disciplinary perspective from which is constituted the starting point of the reconstruction approach regarding the Kantian theoretical program, perspective that has the advantage over the first one to have the capacity of building new theoretical reconstructions away from the historical-systematic context; finally, the last task (and the most relevant here) proposes a different perspective from the two which embraces them altogether as one as the most qualified overview that, on the one hand, can solve the theoretical difficulties of the Kantian program of the Critique which the exegesis are dealing with (but not those problems alone) and on the other hand is able to offer the possibility of new theoreticalsystematic openings of the Critique to present.
