Abstract

This article maintains that Jean-Paul Sartre’s early masterwork, Being and Nothingness, is primarily concerned with developing an original approach to the being of consciousness. Sartre’s ontology resituates the Cartesian cogito in a complete system that provides a new understanding of negation and a dynamic interpretation of human existence. The article examines the role of consciousness, temporality and the relationship between self and others in the light of Sartre’s arguments against “classical” rationalism. The conclusion suggests that Sartre’s departure from modern foundationalism has “postmodern” implications that emerge in the areas of ontology, existential analytics and the ethics of human freedom.
