Why the most famous slogan of the 1968 student protests was written by a ghost

In short: Paul Nizan was a philosopher, novelist, and communist who died in battle before his ideas fully ignited the French student movement. His cynical, sharp-edged prose captured the alienation of the middle class, leaving behind a legacy that remains as politically ambiguous as it is intellectually provocative.

Born in 1905, Paul Nizan was a brilliant contemporary of Jean-Paul Sartre, with whom he studied in Paris. His early life was marked by a restless search for identity, oscillating between the priesthood, fascist sympathies, and eventually, a committed membership in the French Communist Party. This volatile political journey informed his writing, which focused on the crushing weight of social alienation and the precarious position of the petit-bourgeoisie caught between competing class forces.

Nizan’s literary output, including novels like Antoine Bloye and The Conspiracy, often drew from his own life. Antoine Bloye, for instance, was inspired by his father’s career in the French railway bureaucracy. His essay The Watchdogs served as a scathing critique of materialist philosophy, cementing his reputation as a committed intellectual. Yet, he was never a dogmatic teacher; he famously encouraged his students to think for themselves rather than blindly adopting his own Marxist perspectives.

His break with the Communist Party in 1939, triggered by the Molotov–Ribbentrop Pact, was not driven by moral outrage but by a cold, strategic assessment. Nizan criticized his former comrades for lacking the political cynicism necessary to navigate dangerous diplomatic waters. Shortly after this departure, he enlisted in the French army. He was killed in action in May 1940 during the German offensive against Dunkirk.

Decades after his death, Nizan’s work found a second life. His 1931 memoir, Aden Arabie, was republished in 1960 with a foreword by Sartre. Its opening line, which rejected the notion that one's twenties are inherently the best years of life, became a defining rallying cry for the May 1968 student protests. Today, Nizan remains a complex figure—a man whose writings anticipated the radical existentialism of the postwar era while his own political allegiances remain a subject of intense historical debate.
