Recent work at the intersection of moral philosophy and the philosophy of psychology has dealt mostly with Aristotelian virtue ethics. The dearth of scholarship that engages with Hume¿s moral philosophy, however, is both noticeable and peculiar. Hume's Moral Philosophy and Contemporary Psychology demonstrates how Hume¿s moral philosophy comports with recent work from the empirical sciences and moral psychology. It shows how contemporary work in virtue ethics has much stronger similarities to the metaphysically thin conception of human nature that Hume developed, rather than the metaphysically thick conception of human nature that Aristotle espoused. It also reveals how contemporary work in moral motivation and moral epistemology has strong affinities with themes in Hume¿s sympathetic sentimentalism.
