An Essay on the Nature and Conduct of the Passions and Affections (1742, 2002)

The first half of the work presents a rich moral psychology built on a theory of the passions and an account of motivation deepening and augmenting the doctrine of moral sense developed in the Inquiry. The second half of the work, the Illustrations, is a brilliant attack on rationalist moral theories and is the font of many of the arguments taken up by Hume and used to this day.
