One solution to the problem of moral knowledge is to claim that we can acquire it a posteriori through moral experience. But what is a moral experience? When we examine the most compelling putative cases, we find features which, I argue, are best explained by the hypothesis that moral experiences are emotions. To preempt an objection, I argue that putative cases of emotionless moral experience can be explained away. Finally, I allay the worry that emotions are an unsuitable basis for (...) moral knowledge. I conclude that those who believe in moral experience should hold that it consists of emotion. (shrink)
