ABSTRACTThis paper takes inspiration from Books III and IV of the Nicomachean Ethics, which discuss the ways in which the student of virtue can go wrong with respect to different vices. It uses this discussion to draw some conclusions about Aristotelian habituation. I will argue that habituation is an appropriate learning strategy for many kinds of students of virtue, not just children; that habituation is multi-faceted and involves habits of emotions, habits of reason and habits of action; and that habituation is messy because it reflects a messy subject matter. I will conclude with some thoughts on how educators can best respond to this messiness.KEYWORDS: Aristotlevirtue ethicshabituation AcknowledgementsI am grateful to the audience at the Gdansk conference on Virtue and Human Development as well as three referees for very helpful comments on earlier versions of this paper.Disclosure statementNo potential conflict of interest was reported by the author(s).Notes1.
