The Eudemian Ethics is a major treatise on moral philosophy whose central concern is what makes life worth living. Aristotle considers the role of happiness, and what happiness consists of, and he analyses various factors that contribute to it: human agency, the relation between action and virtue, and the concept of virtue itself. Moral and intellectual virtues are classified and considered, and finally the roles of friendship and pleasure. It deals with the same issues as the better-known Nicomachean Ethics, with which it holds three books in common, and its special qualities, as well as the similarities and differences between the two works, are of fundamental concern to anyone interested in Aristotle's philosophy.

This is the first time the Eudemian Ethics has been published in its entirety in any modern language. Anthony Kenny's fine translation is accompanied by a lucid introduction and explanatory notes, which assist the reader in understanding this important work.
