Aristotle's Nicomachean Ethics, based on lectures that he gave in Athens in the fourth century BCE, is one of the most significant works in moral philosophy, and has profoundly influenced the whole course of subsequent philosophical endeavor. Topics covered include the role of luck in human wellbeing, responsibility, courage, justice, friendship and pleasure. This accessible new translation follows the Greek text closely and also provides a non-Greek reader with something of the flavor of the original. The volume also includes a historical and philosophical introduction and notes on further reading.
