Also sprach 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; it was published in four volumes between 1883 and 1885. The protagonist is nominally the historical Zoroaster. Much of the book consists of discourses by Zarathustra on a wide variety of subjects, most of which end with the refrain, "Thus spoke Zarathustra". The character of Zarathustra first appeared in Nietzsche's earlier book The Gay Science (at §342, which closely resembles §1 of "Zarathustra's Prologue" in Thus Spoke Zarathustra). The style of Zarathustra has facilitated varied and often incompatible ideas about what Zarathustra says. Zarathustra's "[e]xplanations and claims are almost always analogical and figurative". Though there is no consensus about what Zarathustra means when he speaks, there is some consensus about that which he speaks. Thus Spoke Zarathustra deals with ideas about the Übermensch, the death of God, the will to power, and eternal recurrence.
