Existentialism emerges in literature

The body of philosophical doctrine known as existentialism, which has its origins in the writings of the 19th-century philosophers Søren Kierkegaard, Arthur Schopenhauer, and Friedrich Nietzsche, found its most famous literary expression in the works of French writers who emerged in the 1940s. The works of Jean-Paul Sartre, Albert Camus, and Simone de Beauvoir explored the central existentialist theme—the primacy of individual choice in an absurd world that offers no absolute truths on which to rely.

The development of existentialism as a philosophical doctrine in the 20th century was largely influenced by the German philosophers Martin Heidegger and Karl Jaspers, who in the 1920s and 1930s laid the groundwork for the French existentialists to come. Sartre, who was strongly influenced by Heidegger's ‘Being and Time' (1943), presented the fullest exposition of his philosophical doctrine in ‘Being and Nothingness' (1943). Sartre emphasized the idea of living authentically—accepting responsibility for making one's own choices, and thus creating one's own existence, even in the face of the world's ultimate absurdity. Those who fail to accept this responsibility live in a condition known as “bad faith.” Sartre examined these ideas in novels such as ‘Nausea' (1938) and in plays such as ‘The Flies' (1943) and ‘No Exit' (1945). De Beauvoir, a longtime companion of Sartre, explored the same themes in her novels, including ‘She Came to Stay' (1943) and ‘The Mandarins' (1954).

The belief that only individual action can counteract alienation is also reflected in the works of Camus. His essay “The Myth of Sisyphus” (1942) retells the Greek myth of the man condemned by the gods to roll a boulder up a hill for eternity. Because Sisyphus accepts the absurdity of his fate, he is able to rise above it on an intellectual level and finally to exult in his useless task. These themes are echoed in Camus's novels, which include ‘The Stranger' (1942) and ‘The Plague' (1947).

Although it reached its pinnacle in literature during the 1940s and 1950s, existentialism remained a vital part of Western thinking in the latter half of the 20th century. Among the many writers influenced by the philosophy were the dramatists of the Theater of the Absurd.
