Absurdism is a philosophical movement asserting that the human search for meaning is fundamentally at odds with the meaningless, indifferent universe. Founded primarily through Albert Camus's work, especially "The Myth of Sisyphus," absurdism argues that life has no inherent meaning or purpose, yet humans cannot help but seek one—this creates the "absurd" condition. Unlike nihilism, which concludes life is meaningless and valueless, absurdism acknowledges the contradiction without despairing. Instead, it advocates for "revolt" against the absurd by living fully despite meaninglessness, embracing life's experiences without false hope or suicide. Camus uses Sisyphus eternally pushing his boulder as the ultimate absurd hero who finds contentment in the struggle itself. Absurdism occupies a middle ground between existentialism (which seeks authentic meaning through individual choice) and nihilism (which denies all value).
