 Generalists argue that, once spelled out, the perceptual model is not the a posteriori epistemology it might first have seemed but instead commits us to a priori intuitions relating moral features to their grounds. Particularists may grant that basic moral knowledge is a priori knowledge of “what is a moral reason for what” (Dancy 2004: 141) while maintaining that the object of knowledge remains particularized and does not implicate principles. One challenge for the particularist is that “what is a reason for what” in a particular case is contingent, and so the particularist risks being committed to a priori knowledge of contingent truths. In his defense of particularism, Dancy has been willing to embrace this apparent consequence (Dancy 2004; for criticism, see McKeever and Ridge 2006). Other particularists have sought to avoid the implication (Leibovitz 2014).
