Abstract
This paper aims to analyze some theses of Vasco de Magalhães-Vilhena regarding the problem of knowledge, namely, the so-called theory of the “reflex”. The point of departure is the critic the author addresses to António Sérgio, whose philosophical position is correctly characterized as Neo-kantian Idealism. Magalhães-Vilhena aims to link the doctrine of the reflex, inspired by the research of the Russian physiologist I. Pavlov, to the concept of reflection proposed by Hegel in the Second Part of the Science of Logic. In this paper I question the legitimacy of this connection. At last, confronting the standpoint of Magalhães-Vilhena regarding gnosiological issues I propose an analysis of the phenomenon of knowledge based in the principles of intentional analysis endorsed by Edmund Husserl.
