The Industrial Revolution did more than remake factories and cities; it upended how Europe's thinkers understood reality, religion, and freedom, and this film traces that upheaval from Hegel's sweeping systems through Nietzsche's assault on inherited morality to Sartre's existentialism. Historians walk through how German Idealism gave way to materialist and scientific challenges, how Kierkegaard and Nietzsche turned philosophy toward the individual and away from grand metaphysical claims, and how two world wars pushed twentieth-century thinkers like Sartre and Camus toward questions of freedom, meaning, and absurdity in a universe without guaranteed order. The film moves chronologically, using period portraits, archival images, and location footage alongside expert commentary to connect each thinker to the political and scientific shocks of their era, from Darwin to the World Wars. Rather than treating these ideas as museum pieces, it traces direct lines from Hegel's dialectics and Nietzsche's critique of morality to present-day debates in politics, ethics, and psychology, closing on why existentialist questions about freedom and meaning still feel unresolved.
