Through Existentialism, Nothing and Psychoanalysis

While a prisoner of war in 1940 and 1941, Sartre read Martin Heidegger's Being and Time (1927), which uses the method of Husserlian phenomenology as a lens for examining ontology. Sartre attributed the course of his own philosophical inquiries to his exposure to this work. Though influenced by Heidegger, Sartre was profoundly skeptical of any measure by which humanity could achieve a kind of personal state of fulfillment comparable to the hypothetical Heideggerian "re-encounter with Being". In Sartre's account, man is a creature haunted by a vision of "completion" (what Sartre calls the ens causa sui, meaning literally "a being that causes itself"), which many religions and philosophers identify as God. Born into the material reality of one's body, in a material universe, one finds oneself inserted into being. In accordance with Husserl's notion that consciousness can only exist as consciousness of something, Sartre develops the idea that there can be no form of self that is "hidden" inside consciousness. On these grounds, Sartre goes on to offer a philosophical critique of Sigmund Freud's theories, based on the claim that consciousness is essentially self-conscious.

Being and Nothingness is regarded as both the most important non-fiction expression of Sartre's existentialism and his most influential philosophical work, original despite its debt to Heidegger. Many have praised the book's central notion that "existence precedes essence", its introduction of the concept of bad faith, and its exploration of "nothingness", as well as its novel contributions to the philosophy of sex. However, the book has been criticized for its abstruseness and for its treatment of Freud.

Background

Descartes

Sartre's existentialism shares its philosophical starting point with René Descartes: The first thing we can be aware of is our existence, even when doubting everything else (Cogito ergo sum). In Nausea, the main character's feeling of dizziness towards his own existence is induced by things, not thinking. This dizziness occurs "in the face of one's freedom and responsibility for giving a meaning to reality". As an important break with Descartes, Sartre rejects the primacy of knowledge (a rejection summed up in the phrase "Existence precedes essence") and offers a different conception of knowledge and consciousness.

Husserl

Important ideas in Being and Nothingness build on Edmund Husserl's phenomenology. To both philosophers, consciousness is intentional, meaning that there is only consciousness of something. For Sartre, intentionality implies that there is no form of self that is hidden inside consciousness (such as Husserl's transcendental ego). An ego must be a structure outside consciousness, so that there can be consciousness of the ego.
