Sartre Publishes Being and Nothingness

Jean-Paul Sartre published Being and Nothingness, the foundational text of existentialism proclaiming that "existence precedes essence."

In 1943, French philosopher Jean-Paul Sartre published L'Être et le néant (Being and Nothingness), a dense philosophical treatise that became the foundational text of existentialism. Sartre argued that human beings have no predetermined nature or essence — we are "condemned to be free," forced to create ourselves through our choices. Bad faith (mauvaise foi) is the attempt to deny this radical freedom by hiding behind roles, excuses, or determinism. Sartre's philosophy, together with his novels, plays, and political activism, made him the most famous intellectual of the 20th century and turned existentialism into a cultural movement that swept postwar Europe.
