Friedrich Nietzsche Thus Spoke Zarathustra-Penguin Classics Nietzsche was one of the most revolutionary and subversive thinkers in Western philosophy, and"Thus Spoke Zarathustra" remains his most famous and influential work. It describes how the ancient Persian prophet Zarathustra descends from his solitude in the mountains to tell the world that God is dead and that the Superman, the human embodiment of divinity, is his successor. With blazing intensity and poetic brilliance, Nietzsche argues that the meaning of existence is not to be found in religious pieties or meek submission, but in an all-powerful life force: passionate, chaotic and free.
