He is capable of behaving kindly, but he is not kind. He is capable of committing acts of generosity, but he is not generous. He is capable of being loyal, but he is fundamentally disloyal.Testimony of Michael D. Cohen, Committee on Oversight and Reform, U.S. House of Representatives, February 27, 2019


So things done are called just and moderate whenever they are such that the just person or the moderate person would do them; whereas a person is not just and moderate because he does these things, but also because he does them in the way in which just and moderate people do them. So it is appropriate to say that the just person comes about from doing what is just, and the moderate person from doing what is moderate.Aristotle, Nicomachean Ethics 1105b5-11, trans. Rowe and Broadie
