 The scope of this further category became, however, the focus of debate. Supererogatory acts in Urmson’s sense (which is reminiscent of the Catholic doctrine) include only actions that are morally praiseworthy, valuable, although not obligatory in the sense that their omission is not blameworthy. But the general formulation (iv) could consist also of small acts of favor, politeness, consideration and tact, which are good though not morally praiseworthy, which can be expected of people even though not strictly demanded. The latter, wider, definition of supererogation, covers a larger scope of actions that we tend to view as good-though-not-obligatory; but the former, narrow, definition of supererogation as having a unique moral merit better captures the essential value and hence justification of supererogation as a distinct category of moral action, to which Urmson referred as saintly and heroic.
