Existentialism

A philosophical movement holding that existence precedes essence — humans are not born with fixed purpose but must create meaning through choices and lived experience — is existentialism.

Type: Concept Domain: Philosophy Humanities Art Social Science

Overview

Emerging in twentieth-century Europe through Sartre, Camus, Heidegger, and de Beauvoir, existentialism responded to the perceived failure of religious and Enlightenment rationalism to account for individual suffering, freedom, and responsibility. Its central concepts — radical freedom, authenticity, bad faith, and the absurd — shaped both academic philosophy and broader culture.

Why it matters

Existentialism profoundly influenced psychiatry through logotherapy and existential psychotherapy, which address anxiety arising from mortality and meaninglessness as clinical issues. It shaped critical theories of alienation and identity in social science, and its questions about embodied consciousness remain essential to philosophy of mind and debates about AI.
