Wisdom, Political Expertise and the Unity of Virtues in Aristotle

Abstract ‘Unity of virtues’ (UV) in Aristotle is the claim that the ethical virtues are mutually entailing. But commentators typically focus on the fact that wisdom implies all the ethical virtues, without explaining how the ethical virtues themselves are mutually entailing. I argue that the so-called ‘Grand End’ view, understood as applying to both wisdom ( φρόνησις ) and political expertise ( πολιτική ), allows us to give an account of UV at the level of the ethical virtues. By discussing the ethical virtues individually, I show how all the ethical virtues can be seen as different aspects of the philosopher-statesman’s multifaceted character.
