Abstract

Apparent analogues of moral supererogation can be found in other normative domains, such as the prudential domain and the epistemic domain. Vindicating moral supererogation requires a convincing response to the challenge of the ‘paradox of moral supererogation’: if some act would be morally best, why would it not be morally required? Vindicating putative non-moral types of supererogation requires responding to analogous challenges: if some act would be best by the lights of some normative domain, why would it not be required by the lights of that domain’s standards? I argue that the key to responding to such challenges involves giving a substantive account of what requirement is within the domain in question. The most promising type of account, I suggest, is what I call the Critical Reaction Account.
