Hume's Enquiry Concerning the Principles of Morals › Further Reading

- Hume's *A Treatise of Human Nature*, especially Book III, offers a more detailed but less polished treatment of the same themes. Essential for serious students of Hume's ethics. - Adam Smith's *The Theory of Moral Sentiments* develops Humean themes with particular attention to sympathy and the "impartial spectator." Smith was Hume's close friend and intellectual heir. - Jonathan Haidt's *The Righteous Mind* brings Hume's psychology into the twenty-first century, arguing that moral judgment is primarily intuitive and that reason serves mainly as a lawyer for our intuitions. - Simon Blackburn's *Ruling Passions* offers a sophisticated contemporary defense of Humean sentimentalism, engaging with technical debates in metaethics while remaining accessible. - Annette Baier's *A Progress of Sentiments* provides a careful reading of Hume's moral philosophy, emphasizing its connections to his broader epistemology and his account of human nature.
