A major treatise on moral philosophy by Aristotle, this is the first time the <em>Eudemian Ethics</em> has been published in its entirety in any modern language. Equally important, the volume has been translated by Sir Anthony Kenny, one of Britain's most distinguished academics and philosophers, and a leading authority on Aristotle. In <em>The Eudemian Ethics</em>, Aristotle explores the factors that make life worth living. He considers the role of happiness, and what happiness consists of, and he analyzes various aspects that contribute to it: human agency, the relation between action and virtue, and the concept of virtue itself. Aristotle classifies and examines the various moral and intellectual virtues, and he considers the roles of friendship and pleasure in a life well lived. Kenny's superb translation is accompanied by a fine introduction, in which he highlights the similarities and differences between this book and the better-known <em>Nicomachean Ethics</em>, with which it holds three books in common. There are also many useful explanatory notes which clarify the arguments and allusions that Aristotle makes.
