Abstract

In this paper, I argue that in the Eudemian Ethics, Aristotle proposes a strong version of the unity of the virtues. Evidence in favor of this strong version of the unity of the virtues results from reading the common books within the EE rather than as part of the Nicomachean Ethics. The unity of the virtues as defended in the EE includes not only practical wisdom and the character virtues, but also all the virtues of practical and theoretical thinking. Closely related, in the EE, Aristotle proposes a different best agent from the one of the NE. The best agent of the EE is the kalos kagathos. The person who is kalos kagathos has “all” the virtues. Kalokagathia is a whole and the virtues are its parts. I investigate how we should understand this whole and the relation between the individual virtues within this whole.
