The Zoroaster of the book is a sage who lives remote from mankind, and with no attendants but a snake and an eagle. The book is in four parts and all are made up of discourses by Zoroaster. These discourses are delivered to various audiences during the prophet's occasional wanderings and at the conferences he holds with various disciples in the cave that he calls home. They are decidedly oriental in form and recall the manner and phraseology of the biblical rhapsodists. Toward the end Nietzsche throws all restraint to the winds and indulges to his heart's content in the rare and exhilarating sport of blasphemy. There is a sort of parody of the last supper and Zoroaster's backsliding disciples engage in the grotesque and indecent worship of a jackass. Wagner and other enemies of the author appear, thinly veiled, as ridiculous buffoons. In his discourses Zoroaster voices the Nietzschean idea of the superman--the idea that has come to be associated with Nietzsche more than any other. Later on, it will be set forth in detail. For the present, suffice it to say that it is the natural child of the notions put forward in Nietzsche's first book, "The Birth of Tragedy," and that it binds his entire life work together into one consistent, harmonious whole. The first part of "_Also sprach Zarathustra_" was published in 1883, the second part following in the same year, and the third part was printed in 1884. The last part was privately circulated among the author's friends in 1885, but was not given to the public until 1892, when the entire work was printed in one volume. As showing Nietzsche's wandering life, it may be recorded that the book was conceived in the Engadine and written in Genoa, Sils Maria, Nice and Mentone. _"Jenseits von Gut und Böse_" ("Beyond Good and Evil") appeared in 1886. In this book Nietzsche elaborated and systematized his criticism of morals, and undertook to show why he considered modern civilization degrading. Here he finally formulated his definitions of master-morality and slave-morality, and showed how Christianity was necessarily the idea of a race oppressed and helpless, and eager to escape the lash of its masters.
