 Mill, that is to say, believes in the existence of a class of supererogatory acts (Donner 2009: 140–3). While it might be extremely praiseworthy to do the most good that we can—and while there might be reason to do the most good that we can—failure to do so is not the standard that marks the distinction between acting morally and immorally. Rather, Mill claims, the notion of moral wrong is connected to that of punishment.
