¹⁰ This is easier in Greek than in English: in Greek, ‘excellence’ (or ‘virtue’) is the abstract noun for ‘goodness’, and ‘beneficial’ means ‘good for’—so of course the possession of goodness is bound to be good. Greek moralists, however, could cast self-control, qua a ‘quiet’ virtue, as not always helpful, e.g. when forceful action is needed.
