Abstract

Philosophers investigate the nature of morality. And scientists study the moral judgments people make, the moral norms people enforce, and the systems of moral rules people embrace. What is the relationship between these investigations? The traditional philosophical view is that an unbreachable wall divides these activities. Philosophy and science investigate entirely separate domains. Philosophy investigates the normative realm – the true nature of morality. Science investigates the descriptive realm – how different people or groups of people think about morality and how they deploy moral norms and rules. Just as it would be absurd to investigate the nature of the heavens by exploring how different people think about the heavens, it would be absurd to investigate the nature of morality by exploring how different people think about morality
