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 "Übermensch" (superhuman) who would have supreme morality. Ironically, Nietzsche mimics the style of the Bible, fictionalizing Zarathustra as his protagonist.
