Existentialism
Existentialism begins when philosophy stops asking what human beings are in the abstract and asks what they must become in the pressure of a life that offers no ready-made meaning.

Timeline
Birth of Søren Kierkegaard
**1813-05-05** — Kierkegaard is born in Copenhagen into the Danish world that would shape his lifelong suspicion of public religion and social conformity. His later works would turn the problem of inwardness into a philosophical crisis for modern life.
Publication of *Either/Or* and *Fear and Trembling*
**1843** — These books establish Kierkegaard’s method of indirect communication and his account of choice, inwardness, and the leap beyond ethical calculation. They become foundational texts for later existential thought.
Nietzsche announces the death of God in *The Gay Science*
**1882** — Nietzsche’s diagnosis of modern Europe names the collapse of inherited metaphysical certainty and the crisis of value that follows. Existentialists later read this as one of the defining conditions of modern freedom.
Heidegger publishes *Being and Time*
**1927** — Heidegger’s analysis of Dasein, thrownness, anxiety, and being-toward-death reorients existential thinking toward ontology. The book becomes one of the major sources for twentieth-century existential philosophy.
Camus publishes *The Myth of Sisyphus*
**1942** — Camus formulates the absurd as the confrontation between the human demand for meaning and the world’s silence. The book becomes a critical companion to existentialism, sharing its mood while resisting its more heroic conclusions.
Sartre publishes *Being and Nothingness*
**1943** — Sartre’s major philosophical work offers a phenomenology of consciousness, bad faith, and freedom. It gives existentialism its most systematic atheistic form and its most influential vocabulary of responsibility.
Sartre delivers “Existentialism Is a Humanism”
**1945** — The lecture popularizes existentialism and provokes debate over whether the philosophy is a defense of human freedom or a recipe for anguish. It becomes the movement’s most famous public statement.
De Beauvoir publishes *The Ethics of Ambiguity*
**1947** — De Beauvoir recasts existential freedom in ethical terms and argues that ambiguity is the condition of human action. The book becomes a bridge between existentialism and later feminist and political thought.
Publication of *The Second Sex*
**1949** — De Beauvoir’s landmark study shows how existential ideas can analyze gender as a social and historical formation rather than a natural destiny. It becomes one of the twentieth century’s most influential philosophical books.
Camus publishes *The Rebel*
**1951** — Camus sharpens his critique of ideological violence and of philosophies that turn rebellion into historical absolution. The book marks a major rupture between Camus and Sartre’s political circle.
Death of Albert Camus
**1960** — Camus’s death ends one of the most morally demanding branches of existential-adjacent thought. His work continues to influence moral philosophy, literature, and political reflection on revolt and measure.
Renewed public interest in existential themes
**2020** — Under conditions of pandemic anxiety, climate dread, and precarious labor, existential questions about finitude, responsibility, and meaning reappear in philosophy, therapy, and popular culture. The movement’s vocabulary regains urgency in a changed world.
