Abstract

In this paper, I outline and defend a commonly-held moral view which has received surprisingly little sustained philosophical attention. This view, which I call the ‘authority of conscience,’ states that believing ourselves to have moral obligations to act in a certain way does in fact create an obligation to act in that way. Although I do not provide a positive case for the principle of authoritative conscience, beyond its popularity and intuitive force, I defend it against several prima facie objections. I then go on to demonstrate that the principle does not entail any anti-realist metaethical commitments, and is therefore compatible in particular, and contrary to appearances, with plausible formulations of moral realism.
