In Eth. Nic. V 8, Aristotle provides a classification of damages an agent may do, establishing degrees of culpability. In doing so, Aristotle recalls what he said about voluntary and involuntary actions in the preceding books about voluntary and involuntary actions. In this paper, I defend the thesis according to which the Eudemian account on voluntariness is consistent with the classification of damages Aristotle provides in Eth. Nic. V 8, arguing that one of Aristotle’s concerns in dealing with voluntariness is (...) the legal practices of his time, which we can regard as strongly linked to his discussion on moral responsibility. Thereby, I challenge David Charles’ view that the account of voluntariness featured in the book on justice differs both from the Nicomachean account and the Eudemian one. (shrink)
