Abstract
Schopenhauer was the first, and to the end the greatest philosophical influence on Nietzsche, who said it was Schopenhauer who had turned him into a philosopher. For many years the young Nietzsche was a thoroughgoing Schopenhauerian; but then he rebelled against this influence, attacked it and tried to overthrow it. Other substantial intellectual figures of the nineteenth century who were significantly influenced by Schopenhauer include the historian Jacob Burckhardt, author of The Civilization of the Renaissance in Italy; Hans Vaihinger, author of The Philosophy of ‘As If’; Edward von Hartmann, author of The Philosophy of the Unconscious; and Sigmund Freud.
