Annotation. Thus Spake Zarathustra is an important philosophical text by German philosopher Friedrich Nietzsche. In it he begins his exploration of morality, questioning the assumption of Christianity or Judaism as a basis for morality. He wrote about the "death of God" and the "_bermensch" (superhuman) who would have supreme morality. Ironically, Nietzsche mimics the style of the Bible, fictionalizing Zarathustra as his protagonist.
