"In his Blistering Prose, Friedrich Nietzsche (1844-1900) uprooted the traditional study of philosophy as firmly grounded in rationality and truth and lay the foundations for the radicalism of twentieth-century Western thought, as it would emerge after his death. Contemporary thinkers have reinterpreted, revised, and repeated Nietzsche's ideas, but no one has transcended them, and today, no student of philosophy can afford to ignore the life and work of this towering figure. In his seminal work, acclaimed biographer Rudiger Safranski integrates philosophical analysis with biographical detail to portray this difficult, often contradictory man with an objective, even-handed grace." "Following Nietzsche's own dictum that "life is a testing ground for thought," Safranski, the author of biographies of Heidegger and Schopenhauer, offers a critical reappraisal of Nietzsche's philosophy by examining the intersection of his life and work, attempting what Nietzsche considered the most important of human tasks: to be "an adventurer, a circumnavigator of the inner world called human.""--BOOK JACKET
