This essay examines Aristotle's account of justice as a virtue in the Nicomachean Ethics by considering two related parts of it: Aristotle's elevated account of justice as lawfulness and his description of equity as a virtue. I focus on moral rather than legal questions by emphasizing Aristotle's identification of justice as lawfulness with complete virtue, and a broad sense of equity as superlatively good character. Some of the more difficult passages in book 5 prove to be tied together by the question of the goodness of justice and I argue that Aristotle points to a specific confusion in this regard characteristic of virtuous people. I conclude that Aristotle's critique of our ordinary opinions about justice offers crucial, albeit limited, support for the superiority of the contemplative life announced at the end of book 10.
