A close examina t ion of Sartre's discussion of the limits of the self in Being and Nothingness may shed light on his ideas on the nature of Metaphysics, O ntology and Phenomenology. Some implicatio ns of his discussion are presented, centered on his de f e nse of the irre ducibility of the phe nome non of being to the being of the phenomenon when dealing with the passage from phenomenology to ontology, which culminates in his phe nomenological ontology (...) the telos of Being and Nothingness. T he passage to me t a p hy s ics can be fruitfully cont rasted with Bergson's enterprise, because for Sartre metaphysics has a regulative rather than a constitutive function. (shrink)

Este artigo pretende restituir a leitura que Heidegger e Sartre realizam da filosofia de Descartes, desvelando, a partir disso, as diferentes posições interpretativas que ambos os filósofos tomam em relação ao pensamento cartesiano. Observar-se-á que o tratamento dado por Heidegger à metafísica cartesiana explicita um anti-humanismo contrário ao humanismo sartreano. A partir dessa diferença, seremos capazes de assinalar um distanciamento teórico entre Heidegger e Sartre, distanciamento que poderá revelar, por conseguinte, a maneira peculiar pela qual Sartre opera com os conceitos (...) hedeggerianos em L’être et le néant. Palavras-chave: humanismo; anti-humanismo; fenomenologia; liberdade; metafísica.: This article aims to replace the Hedeigger’s and Sartre’s read from Descarte’s philosophy unveiling, from that, the different interpretive positions that both philosophers take in relation to the Cartesian thought. We will observe that the treatment given by Heidegger to the Cartesian metaphysics reveals an anti-humanism contrary from Sartre’s humanism. From this difference, we will be able to point out a theoretical detachment between Heidegger and Sartre, detachment that may reveal, meanwhile, the peculiar way by which Sartre deals with the Heidegger’s concepts in L’être et le néant. Keywords: humanism; anti-humanism; phenomenology; freedom; metaphysics. (shrink)
