Thus Spoke Zarathustra is Nietzsche's most famous and enigmatic work. The philosopher claimed to have given humanity the deepest book through his poetry. To gain clarity about his "gift," a parody of the Bible, the crucial question is: What is Nietzsche's Zarathustra? An enlightened one or a lawgiver? A tempter or a founder of religion? A philosopher or a prophet? Heinrich Meier's book attempts to delve into the core of the drama guided by the question of whether Zarathustra is a philosopher or a prophet. It understands Nietzsche's book for all and for none as an endeavor of clarification and distinction, of self-understanding and self-assurance. It does not see Zarathustra merely as a vessel of a doctrine or as a simple mouthpiece of its creator. It explicitly includes the course of the action and the events.
