Thus Spake Zarathustra: A Book for All and None (ePub)

Thus Spoke Zarathustra: A Book for All and None (German: Also sprach Zarathustra: Ein Buch für Alle und Keinen, also translated as Thus Spake Zarathustra) is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts between 1883 and 1885 and published between 1883 and 1891. Much of the work deals with ideas such as the "eternal recurrence of the same", the parable on the "death of God", and the "prophecy" of the Übermensch, which were first introduced in The Gay Science.
Thus Spoke Zarathustra was conceived while Nietzsche was writing The Gay Science; he made a small note, reading "6,000 feet beyond man and time," as evidence of this. More specifically, this note related to the concept of the eternal recurrence, which is, by Nietzsche's admission, the central idea of Zarathustra; this idea occurred to him by a "pyramidal block of stone" on the shores of Lake Silvaplana in the Upper Engadine, a high alpine region whose valley floor is at 6,000 feet (1,800 m). Nietzsche planned to write the book in three parts over several years. He wrote that the ideas for Zarathustra first came to him while walking on two roads surrounding Rapallo, according to Elisabeth Förster.
