It has long been recognized that anyone seriously interested in Aristotle’s moral philosophy will need to take full account of the Eudemian Ethics, a work still gravely neglected in favor of the better-known Nicomachean Ethics. The relation between the two continues to be the subject of lively scholarly debate. This volume contains a translation of three of the eight books of the Eudemian Ethics–those that are likely to be of most interest to philosophers today–together with a philosophical commentary on these books from a contemporary point of view. Intended to serve the needs of readers of Aristotle without a knowledge of Greek, this book’s aim in translation has been to give as accurate an idea as possible of Aristotle’s text; but for the benefit of those who are able to read the original, there are notes on the Greek text used for problematic passages.
