Audiobook Thus Spoke Zarathustra was conceived and written by Friedrich Nietzsche during the years 1881–1885; the first three parts were published in 1883 and 1884. The book formed part of his ‘campaign against morality’, in which Nietzsche explored the ethical consequences of the ‘death of God’. 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 Übermensch or Superman.
