Thus Spoke Zarathustra - Feedbooks Edition by Friedrich Nietzsche

Thus Spoke Zarathustra: A Book for All and None (German: Also sprach Zarathustra: Ein Buch fuer Alle und Keinen) is a philosophical novel by German philosopher Friedrich Nietzsche. The book chronicles the fictitious travels and pedagogy of Zarathustra, usually known in English as Zoroaster, the Persian prophet and founder of Zoroastrianism. Nietzsche is clearly portraying a "new" or "different" Zarathustra, one who turns traditional morality on its head.
