The circuit of ipseity and its place in Being and Nothingness

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.A circunscrição do tema do circuito da ipseidade em O Ser e o Nada pode esclarecer as inovações sartre a nas em relação ao estatuto da Metafísica, da Ontologia e da Fenomenologia.

A passagem à metafísica pode ser bem delineada através da contraposição com a empresa bergsoniana, já que a metafísica aparece na reflexão de Sartre com uma função puramente reguladora, jamais constitutiva.The Circuit of ipseity and its place in O Ser e o NadaThe circumscription of the theme of the ipseity circuit in O Ser e o Nada can clarify the sartrean innovations in relation to the status of Metaphysics, Ontology and Phenomenology.

The passage to metaphysics can be well delineated through the opposition with the Bergsonian company, since metaphysics appears in the reflection of Sartre with a purely regulatory function, never constitutive
