 Finally, phenomenological evidence has been brought to bear on the various roles that morally relevant reasons for action might play. Dwelling on the controversial category of the supererogatory, Horgan and Timmons (2010a) argue that making sense of the supererogatory as it is normally experienced requires recognizing that in addition to such reasons playing requiring and justifying roles (Gert 2004), we must recognize what they call a “merit-conferring” role for reasons—reasons that morally favor a course of action without prima facie requiring it, let alone requiring it all-things-considered.
