Abstract. There are some good reasons for us to use the concept of “moral realism”, in the following sense: moral realism asks us to think of morality as independent of the will. It entails moral optimism — that all other things equal, the interests of the right will triumph. Moreover, it suggests that some interests are objective because we didn’t choose them. If moral claims are “real”, it’s because they have a force whether we want them or not. Yet if moral regularities are “real”, it is because it derives from instincts (sympathy and resentment) that are independent of the will. And, perhaps, instinctive sympathy and resentment are more important than the other parts of our psychology. If so, then moral realism is defensible because moral norms hold (for morally competent observers) whether we want them or not.
