More Supererogatory

Abstract

If acts can be supererogatory, presumably some can be more supererogatory than others, or further beyond the call of duty. This paper explains how this is possible within a general account of supererogation that sees it arising when a prima facie duty, for example to promote other people’s good, is outweighed by a prima facie permission to promote one’s own good. An act is then more supererogatory when the permission outweighs the duty by more, or when the gap between its strength and that of the duty’s is larger. The paper contrasts its permission-based account of supererogation with a more common one typified by Parfit in On What Matters, which rests it on a conflict between two ‘reasons’ that, despite their differing contents, are of the same deontic type and have the same favouring force. Alongside several other weaknesses, Parfit’s account doesn’t allow differing degrees of supererogation but must treat all supererogatory acts as on a par.
