Standing Your Ground on Moral Disagreement

ABSTRACT Moral disagreement is often invoked to support skeptical conclusions about moral judgment, typically by modeling it on the epistemology of peer disagreement. On the dominant picture, disagreement with a peer supplies higher‐order evidence of error and thereby rationally requires suspension of judgment or a substantial reduction in confidence. We argue that this evidential picture is problematic, especially in the moral domain. First, the conditions for epistemic peerhood are difficult to specify and apply without arbitrariness, and this undermines the assumption that disagreement is a uniform sign of error. Second, even where peerhood conditions are plausible, moral disagreement need not play the specific evidential role presupposed by the skeptical argument. Drawing on resources from social epistemology, we develop an alternative framework on which persistent moral disagreement can function as a structured form of collective inquiry, regulated by argumentative practices and epistemic institutions. On this view, steadfastness is not automatically a sign of epistemic arrogance; under appropriate conditions, it is compatible with epistemic humility, and it can contribute to both epistemic and moral improvement.
