Lore & Background
In the book, 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. The book introduces the concept of bad faith, which describes one's self-deception about human reality, taking two forms: making oneself falsely believe not to be what one actually is, or conceiving oneself as an object and thereby denying freedom.
Reader's Guide
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. Sartre's existentialism shares its philosophical starting point with René Descartes, but rejects the primacy of knowledge, summed up in the phrase 'Existence precedes essence'. The book builds on Edmund Husserl's phenomenology, particularly the idea that consciousness is intentional, but Sartre rejects Husserl's transcendental ego, arguing that an ego must be a structure outside consciousness.
