 It should be noted that in virtue-based ethics (for example Aristotle’s) the demarcation issue becomes moot: supererogatory transcendence of the demands of morality does not play a major role since ethical norms do not consist of well-defined moral duties with which supererogation is correlated. There are contemporary attempts to analyze supererogation in terms of virtue (Kawall 2009), but they seem to fall into circularity: if the supererogatory is defined as what the (idealized) perfectly virtuous person would judge to be so, we still have to decide, independently of a theory of supererogation, who this ideal moral agent is. The ideal of virtue is therefore not very helpful in providing us with criteria for supererogation and for its demarcation from duty.
