ABSTRACT
Sartre’s philosophical thought takes off from a revised conception of the Cartesian cogito, but its distinguishing features arise from the successive ways that he synthesizes this conception with key elements from the philosophical theories of Husserl, Heidegger, Hegel, and Marx. His early phenomenological approach is motivated by Husserl’s phenomenology; his phenomenological ontology synthesizes his revision of Husserl’s phenomenology and Heidegger’s ontology within a framework that is roughly Hegelian in nature; and his dialectical phenomenology constitutes a phenomenological revision of Marx’s dialectic. What unifies these successive moves is Sartre’s aim of revitalizing philosophy with a robust account of individual subjectivity.
