 Qualified versions of supererogationism try to salvage a prescriptive element in the analysis of the concept without collapsing supererogation into duty (which would amount to denying its separate existence). Identifying supererogation with a weaker kind of duty, an imperfect duty, a non-universalizable duty, an ‘ought’ rather than a duty are all forms of recognition of supererogatory acts but only as being an integral part of an overall conception of duty. They maintain the deontic integrity of the moral system but by that run the risk of losing sight of what makes supererogatory action uniquely meritorious, sometimes praiseworthy, and often touching.
