Thus Spoke Zarathustra: A Book for All and None (German: Also sprach Zarathustra: Ein Buch f r Alle und Keinen, also translated as Thus Spake Zarathustra) is a philosophical novel by German philosopher Friedrich Nietzsche, composed in four parts. 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 bermensch, which were first introduced in The Gay Science.
