Abstract

One of the most mature achievements of the Cartesian philosophy is the aim to diffuse Descartes’ thought among a wider audience by presenting his philosophy in an encyclopedic way. A relevant contribution in this field is Pierre Sylvain Régis’s Système. Régis’s contribution consists both in reconciling the new scientific discoveries with les principes de Monsieur Descartes by combining them into a scholarly manual whose aim is to stimulate the ars inveniendi and in recognizing the relevance of Arnauld’s and Nicole’s L’art de penser as manual of Cartesian logic. In an article published on the «Annali della Scuola Normale Superiore di Pisa», pp. 517-55: L’«Art de penser» nella logica del «Système» di Régis) I analysed Régis’s logic in order to point out that, even if L’art de penser represents its only source, La logique of the Système has not to be considered as a mere compendium of the Port-Royal Logique, but as a revision of the latter according to a specific philosophical system, characterized by the empirical interpretation of Descartes’s philosophy. In this paper I provide a synopsis of the comparison between the logic of the Système and the Logique of Port-Royal, in order to resume in a schematic way the results of my research.
