 We are often told that the moral theories defended by modern philosophers fall into two types. On the one hand are rationalist positions developed by thinkers such as Samuel Clarke, William Wollaston, and Richard Price. The rationalists, it is said, believe that reason is the basis of morality, as morality is (in some sense) both grounded in and grasped by reason. On the other hand are sentimentalist positions championed by philosophers such as the Third Earl of Shaftesbury, Francis Hutcheson, and David Hume. The sentimentalists, it is claimed, hold that affect is the basis of morality. According to the standard classification, the sentimentalists believe that morality has relatively little to do with reason, as it is (in some sense) both grounded in and discerned by sentiment.
