Abstract

What is the role of affect in moral epistemology? Sentimentalists assert that moral knowledge is rooted in knowledge of specific situational moral truths, which affect is a necessary means for attaining. Rationalists claim moral knowledge is rooted in moral principles, knowledge of which is acquired a priori through reason alone; affect is unnecessary. Note that in this way of framing the debate, the issue concerns solely moral knowledge. Recent epistemology, however, has also highlighted the importance of understanding as an epistemic good separate from knowledge. As such, moral understanding might have value over and above mere moral knowledge. Some philosophers have pointed to the importance moral understanding possesses for reliably doing the right thing, justifying yourself to others, developing virtue, and performing morally worthy action. In this paper, I argue that the sentimentalist account of understanding both specific moral truths and moral principles has significant advantages over, and can ground, the rationalist alternative.
