'Ought' in Aristotle's Nicomachean Ethics

Much attention has been paid to the issue of whether, in the Nicomachean Ethics, Aristotle uses what we would recognize as deontic concepts. On the basis of a study of dei and other constructions I argue that Aristotle's use of them is often misconstrued and should be interpreted as giving reasons that are reasons of virtue, not a distinct alternative. Many issues remain live in the interpretation (and the translation) of Aristotle's Nicomachean Ethics; in this essay I offer a contribution to one of these, the nature and role of deontic concepts in the work. I offer this essay with pleasure to a celebration of Terry and Gail's work.
