Friedrich Nietzsche was a brilliant German thinker who influenced most of the outstanding European philosophers and writers of the first half of the 20th century. He heralded the emergence of the superman and "free spirits," rebelling against all moral principles and God himself. With his characteristic paradoxical thought and profound psychological analysis, Nietzsche debunked moral prejudices and reconsidered European culture.

The treatise "Thus Spoke Zarathustra" is called Nietzschean Bible.
It formulates Nietzsche's favorite idea—the Superman, who, for the author, is a moral model, the meaning of existence, something to strive for.
