The Moral Sentiments in Hume and Adam Smith

A sentimentalist theory of morality explains all moral evaluations as manifestations of certain emotions, ones that David Hume and Adam Smith, in their related but divergent accounts, call moral sentiments. The two theories have complementary successes and failures in capturing familiar features of the experience of making moral evaluations. Thinking someone courageous or dishonest need not involve having goals or feelings of desire, and Hume’s theory captures that well; but its account of how our moral evaluations are about or directed toward people or actions is deficient. Smith’s theory readily explains how moral sentiments can be about things (and which things they are about), but at the cost of construing some central moral evaluations as goal-directed desires that are simply not like that. Present-day sentimentalists also face the challenge of combining these two desiderata.
