Nietzsche's philosophy exercised a mesmerizing influence on twentieth-century thought, and continues to be a significant source of inspiration for work in all the major branches of philosophical inquiry. "A Companion to Nietzsche" showcases contemporary research and scholarship, and provides a comprehensive guide to all the main aspects of Nietzsche's philosophy.

This is followed by major sections on Art, Nature, and Individuation; Nietzsche's Philosophy of the Future; Philosophy of Mind; Philosophy and Genealogy; Ethics; Politics; Aesthetics; and Evolution and Life. In addition, there are fresh treatments of Nietzsche's core and enigmatic doctrines such as eternal recurrence, the will to power, and the overhuman. The volume profiles the latest research into Nietzsche's texts (published and unpublished) and reflects trends in recent scholarship, such as the renewed focus on Nietzsche's naturalism and interest in his philosophy of time, of nature, and of life.
