Throughout his career, 19th-century philosopher Friedrich Wilhelm Nietzsche explored the concept of the will to power, interpreting it variously as a psychological, biological, and metaphysical principle. This posthumously published volume collects his notes on the force that drives humans toward achievement, dominance, and creative activity. Its reflections on art, morality, Christianity, nihilism, and other topics offer absorbing glimpses into the mind of a great thinker.
