In Nicomachean Ethics 2.4 Aristotle distinguishes between virtuous action and acting virtuously: a virtuous action counts as virtuously performed if done with knowledge, chosen for its own sake, and from a stable character. Since the ‘same’ action can be performed virtuously or non-virtuously, interpreters have concluded that these ‘agential conditions’ are indifferent incidental features with no bearing on the virtuous character of the action. I propose that they are instead ‘perfections,’ i.e., constitutive features of virtuous action as such, admitting of (...) degrees. Unlike the alternative interpretation, my proposal fully harmonizes with three important Aristotelian doctrines: that action from virtue is prior to action merely in conformity with virtue; that character virtue is a perfection of human beings; and that practical life is not properly characterized in transitive, productive terms. My proposal still allows for a generic sense of ‘sameness’ in which the ‘same’ action may be virtuously or non-virtuously performed. (shrink)
