Georg Wilhelm Friedrich Hegel

Hegel's imprint on Western philosophy is unmatched in systemic ambition and breadth of influence. His core idea: reason is not static truth but a movement that absorbs every contradiction.

Born to a civil servant in Wurttemberg, he shared a Tubingen seminary room with Schelling and Holderlin, celebrating the French Revolution together. That fervor seeded his conviction that freedom realizes itself through history. After graduation he worked as a tutor while forging a path that inherited Kant and integrated Fichte's and Schelling's idealism.

The Phenomenology of Spirit (1807) is among philosophy's most ambitious works. Tracing consciousness from sensory certainty to absolute knowledge, it contains the famous master-slave dialectic -- an analysis Marx and Sartre would draw on directly. As Hegel finished writing, Napoleon entered Jena; he reported seeing "the world-spirit on horseback."

Dialectics is his central method. Often simplified as thesis-antithesis-synthesis, Hegel stressed Aufhebung (sublation): to negate, preserve, and elevate at once. Contradiction drives understanding forward. Appointed to Berlin's philosophy chair in 1818, he argued in the Philosophy of Right that the state is the highest realization of ethical life. His Lectures on the Philosophy of History declared world history "progress in the consciousness of freedom."

After his death from cholera in 1831 his students split into Right and Left camps. Through Feuerbach, the Left became Marx's historical materialism. Kojeve's Paris lectures later influenced Sartre and Lacan, the Frankfurt School adopted his dialectics, and a recent Anglophone revival led by Brandom confirms his enduring relevance.
