This book, first published in 2005, explores the historical contextualization of Nietzsche's thought, focusing on his controversial Thus Spoke Zarathustra. The fourth part of Nietzsche's Zarathustra consists of Zarathustra's encounter with eight 'higher men' whom Zarathustra meets in succession on his path. The prophet then invites each individual to his cave for the evening festivities, culminating in a blasphemous festival in which his guests worship an ass as God. Revealing each guest's specific characteristics and distinct roles, the author attempts to discern 'who' these guests are or represent (historically) through glimpsing the characteristics specific to each guest.
