 Throughout the eighteenth century there was considerable disagreement, which continues today, between sentimentalists and rationalists, about the basis or origin of morals. On the sentimentalist side were those, such as Hutcheson and Hume, who thought that our moral faculty was grounded, not in our ability to reason, but in our capacity to experience emotions, and pleasure or displeasure—in short, in our sentiments. “Morality is more properly felt than judged of” (Hume 1739–40: 470; Book III, Part I, Section 2). We are so constituted that we take pleasure in contemplating some characters and actions, while we are displeased by others. Reason does indeed play a role in moral agency, but a subordinate one. Once our feelings have selected our ends, then we need to use reason to find suitable means to those ends. Despite some differences, most humans share many of their basic emotional responses; we tend to care about the same things. It is in virtue of this widespread agreement that there can be a shared standard of morality. But such agreement is contingent; we can imagine agents very different from ourselves in their emotional make-up. If other agents share our moral outlook it will not be in virtue of our common rationality, but as a result of their having a similar range of affective responses to us.
