One of the century's greatest philosophers, without whom there would be no Sartre, no Foucault, no Frankfurt School, Martin Heidegger was also a man of great failures and flaws, a Faustus who made a pact with the devil of his time, Adolf Hitler. The story of Heidegger's life and philosophy, a quintessentially German story in which good and evil, brilliance and blindness are inextricably entwined and the passions and disasters of a whole century come into play, is told in this brilliant biography.

Heidegger grew up in Catholic Germany where, for a chance at pursuing a life of learning, he pledged himself to the priesthood. Soon he turned apostate and sought a university position, which set him on the path to becoming the star of German philosophy in the 1920s. Rudiger Safranski chronicles Heidegger's rise along with the thought he honed on the way, with its debt to Heraclitus, Plato, and Kant, and its tragic susceptibility to the conservatism that emerged out of the nightmare of Germany's loss in World War I. A chronicle of ideas and of personal commitments and betrayals, Safranski's biography combines clear accounts of the philosophy that won Heidegger eternal renown with the fascinating details of the loves and lapses that tripped up this powerful intellectual.
