 There are of course many other examples of supererogatory action although the length and nature of the list is dependent on the definition of supererogation we adopt and the view of its value. But to the extent that actions and forbearances are supererogatory we may summarize their source of value as belonging either to their good consequences (as in the case of giving and charity) or to the strength of character or virtue of the agent (as in the risky acts of heroism) or to the pure good will involved in choosing to do what lies beyond duty (volunteering, forgiveness, small favors).
