In light of this alternative account, we may conclude that the nature of Hume’s compatibilist strategy is significantly misrepresented by the classical interpretation. Hume’s arguments purporting to show that necessity is essential to morality are intimately connected with his discussion of the indirect passions and the specific mechanism that generates the moral sentiments. Whereas the classical interpretation construes his arguments as conceptual or logical in nature, the naturalistic interpretation presents Hume as concerned to describe the circumstances under which people are felt to be responsible. Interpreted this way, Hume’s arguments constitute a contribution to descriptive moral psychology and, as such, they are an important part of his wider program to “introduce the experimental method of reasoning into moral subjects” (which is the subtitle of the Treatise).
