Abstract

Concerning Descartes and Kant, Michel Fichant and Jean Luc Marion claim that “when Kant thinks, Descartes still implicitly advances”. Yet, is a convergence among ontological theses (Heidegger) sufficient to nullify divergences among methodological grounds? To refuse the relationship of inherency "Descartes in Kant”, it is necessary to move from the standpoint of being to that of thinking, and observe in what sense words like “evidence” and “certainty”, once redefined by Kant, clarify the originality of the methodological problem of the Critique of Pure Reason.
