Nietzsche’s work was heavily influenced by ancient Greek philosophy. Meyer shows how Nietzsche attempted to revive the Heraclitean-Protagorean position that is critically analyzed by both Plato and Aristotle in the Theaetetus and Metaphysics IV, and establishes Nietzsche as a naturalist who believes that there are objective facts.The book not only highlights the foundations of his thought, but also restores order to Nietzsche’s work.
