Xenosaga: Episode III - Also Sprach Zarathustra

"Also Sprach Zarathustra" is the title of one of the most famous works of German philosopher Friedrich Wilhem Nietzsche (Also sprach Zarathustra. Ein Buch für Alle und Keinen / Thus Spoke Zarathustra. A Book for Everyone and Nobody). Provocative and influential, the book is unique in the sense it is narrated around the teachings of the ancient Persian prophet Zarathustra.

The book (actually a collection of volumes) is better known for summarizing some of the more controversial aspects of Nietzsche's philosophy, including the concept of a dead god and the "Übermensch" which has been credited as a heavy influence of the Nazi regime.

"Also Sprach Zarathustra" is also the title of an heroic symphony composed by Richard Strauss (based on Nietzsche's work) and is better known for the inclusion of a few of its movements in Stanley Kubrick's film "2001: A Space Odyssey" (based on the novel of the same name by Arthur C. Clarke).
