Aristotle belongs to the small class of philosophers who were not only influential in a particular field of philosophy but also shaped the profile of every philosophical discipline. In this book Otfried Höffe provides a comprehensive introduction to the life and work of Aristotle, covering well-known Aristotelian topics such as ethics, politics, and metaphysics as well as the less familiar, such as biology, psychology, and rhetoric. Höffe also compares Aristotle to other major figures in the history of European (especially German) philosophy, making connections to Kant and Hegel that are particularly insightful. A picture of Aristotle emerges as a philosopher who is much more modern than previously thought, one whose writings are still relevant today and continue to make valuable contributions to many contemporary philosophical debates.
