The Nicomachean Ethics

The work consists of ten books, originally separate scrolls, and is understood to be based on notes said to be from his lectures at the Lyceum which were either edited by or dedicated to Aristotle's son, Nicomachus. In many ways this work parallels the similar Eudemian Ethics, which has only eight books, and the two works can be fruitfully compared. Books V, VI, and VII of the Nicomachean Ethics are identical to Books IV, V, and VI of the Eudemian Ethics.
