This was conceived and written by Friedrich Nietzsche during the years 1881-1885; the first three Parts were published in 1883 and 1884.

Heavily critical not only of Christian values but also of their modern replacements, Thus spoke Zarathustra argues for a new value-system based around the prophecy of the Ubermensch, or Superman. Its appropriation by the National Socialist movement in Germany early in the twentieth century has tainted its reputation unjustly; but there are signs that the rehabilitation of Nietzsche, and of this his most incendiary work, is almost complete. Read by Alex Jennings, there are helpful introductions to every chapter.
