Epistemic Reductionism and the Moral-Epistemic Disparity

In previous work, I defend the following disparity between moral and epistemic facts: whereas moral facts are irreducibly normative, epistemic facts – facts such as that some subject is epistemically justified in believing something – are reducible to facts from some other domain (such as facts about probabilities).  This moral-epistemic disparity is significant because it undercuts an important kind of argument for robust moral realism.  My defense of epistemic reductionism and of the moral-epistemic disparity has been criticized by Richard Rowland (2013) and by Terence Cuneo and Christos Kyriacou (forthcoming). This paper aims to rebut these criticisms and, more generally, to clarify and strengthen the case for epistemic reductionism and the moral-epistemic disparity.
