This chapter shows how the projection of pleasure and pain can be integrated into a subtle form of realism. It is argued that Hume's account of the moral sense can be seen as modelled on a view of primitive animal cognition, whereby what is good for the animal is made salient in pleasurable experience; what is bad for it through painful experience. The moral pleasure and pains render salient Hume's catalogue of the morally relational values, namely that which is useful or pleasing.
