 Aristotle wrote two ethical treatises: the Nicomachean Ethics and the Eudemian Ethics. He does not himself use either of these titles, although in the Politics (1295a36) he refers back to one of them—probably the Eudemian Ethics—as “ta êthika”—his writings about character. The words “Eudemian” and “Nicomachean” were added later, perhaps because the former was edited by his friend, Eudemus, and the latter by his son, Nicomachus. In any case, these two works cover more or less the same ground: they begin with a discussion of eudaimonia (“happiness”, “flourishing”), and turn to an examination of the nature of aretê (“virtue”, “excellence”) and the character traits that human beings need in order to live life at its best. Both treatises examine the conditions in which praise or blame are appropriate, and the nature of pleasure and friendship; near the end of each work, we find a brief discussion of the proper relationship between human beings and the divine.
