Jean-Paul Sartre: Existentialism’s Defining Voice

Jean-Paul Sartre (21 June 1905 – 15 April 1980) was a French philosopher, political activist, and writer. He was a leading figure in 20th-century French philosophy and a key architect of existentialism, whose work shaped sociology, critical theory, post-colonial studies, and literary criticism.

Early Life and Education

Sartre was born in Paris on 21 June 1905, the only child of Jean-Baptiste Sartre, a French Navy officer, and Anne-Marie Schweitzer. His father died of illness when Sartre was two years old, likely contracted in Indochina. Anne-Marie returned to her parents’ house in Meudon, where Sartre was raised by his mother and grandfather, Charles Schweitzer, a German teacher who introduced him to mathematics and classical literature. The theologian and physician Albert Schweitzer was his cousin.

At age twelve, Sartre’s mother remarried and the family moved to La Rochelle, where he experienced bullying partly due to his wandering right eye. As a teenager in the 1920s, he discovered philosophy through Henri Bergson’s essay Time and Free Will. He attended the Cours Hattemer, a private school in Paris, then studied at the École Normale Supérieure, where he earned certificates in psychology, history of philosophy, logic, general philosophy, ethics, sociology, and physics. His 1928 MA thesis, supervised by Henri Delacroix, examined the role and nature of images in psychological life. At ENS, Sartre began a lifelong friendship with Raymond Aron and befriended Paul Nizan, whom he considered his alter ego. He attended Alexandre Kojève’s seminars for several years, an influence he later identified as decisive for his philosophical development.

Career and Achievements

Sartre taught in several French lycées early in his academic career. Around 1928, he was hired as a private French tutor by Japanese philosopher Kuki Shūzō. His engagement with phenomenology crystallized in 1932 after a conversation with Raymond Aron about Edmund Husserl’s work. During World War II, Sartre was drafted, captured, and later released. He then co-founded the resistance group Socialisme et Liberté, which eventually dissolved. After the war, he co-founded the journal Les Temps modernes and became an increasingly influential voice for political causes.

His principal philosophical work, Being and Nothingness (1943), explored the conflict between oppressive conformity—which he termed mauvaise foi (bad faith)—and authentic existence. He provided an accessible introduction to his philosophy in Existentialism Is a Humanism (1946), originally delivered as a lecture. During the occupation, he wrote the play No Exit. Throughout his life, Sartre supported anti-colonial movements, condemned French policies in Algeria, opposed U.S. intervention in Vietnam, and aligned himself with Marxism and Maoism at various points.

Notable Events and Milestones

In 1927, Sartre co-wrote an antimilitarist satirical cartoon for the school revue with Georges Canguilhem, upsetting director Gustave Lanson. That same year, he orchestrated a prank with classmates following Charles Lindbergh’s New York-Paris flight, calling newspapers to report a false honorary degree ceremony. Thousands of people, including journalists, gathered on 25 May, and the scandal led Lanson to resign.

Sartre’s open relationship with existentialist philosopher Simone de Beauvoir became central to his life. Together they challenged the bourgeois cultural and social assumptions of their upbringings through both lifestyle and thought. Despite declining health in his later years, Sartre remained committed to activism and intellectual debate until his death on 15 April 1980. His funeral drew 50,000 mourners.

Awards and Honors

Sartre was awarded the 1964 Nobel Prize in Literature. He attempted to refuse the prize, stating that he always declined official honors and that a writer should not allow himself to be turned into an institution.
