ABSTRACT
Friedrich Nietzsche has been a central influence on many of the most dominant intellectual figures of the twentieth century. Though existentialism is largely a twentieth-century movement and centers on the philosophy of Jean-Paul Sartre, it was anticipated and inspired by Nietzsche and Soren Kierkegaard. Psychoanalysis is both a psychological theory and a school of practical therapy, whose founder and chief theorist Sigmund Freud wrote of Nietzsche that "he had a more penetrating knowledge of himself than any man who ever lived or was likely to live". Works of Nietzsche's such as Beyond Good and Evil: Prelude to a Philosophy of the Future still exert a dominant influence over continental philosophers, and Gilles Deleuze has claimed it is "clear" that "modern philosophy has largely lived off Nietzsche". The philosopher Alasdair MacIntyre also gives a critique of contemporary values from a historical perspective, publishing a compilation of papers under the title Against the Self-Images of the Age.
