Così parlò Zarathustra

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 work of philosophical fiction written by German philosopher Friedrich Nietzsche between 1883 and 1885. The protagonist is nominally the historical Zarathustra, but, besides a few sentences, Nietzsche is not particularly concerned with any resemblance. Much of the book purports to be what Zarathustra said, and it repeats the refrain, "Thus spoke Zarathustra". The style has facilitated variegated and often incompatible ideas about what Zarathustra says. "Zarathustra speaks about stars, animals, trees, tarantulas, dreams, and so forth". Though there is no consensus with what Zarathustra means when he speaks, there is some consensus with what he speaks about. Zarathustra deals with ideas about the Übermensch, the death of God, the will to power, and eternal recurrence. Zarathustra himself first appeared in Nietzsche's earlier book The Gay Science. Nietzsche himself has suggested that his Zarathustra is a tragedy and a parody. It was his favourite of his own books. He was aware, however, that readers might not understand it. Possibly this is why he subtitled it A Book for All and None. Its themes and general merit are continually disputed. It has nonetheless been hugely influential in various facets of culture.
