This paper defends both an interpretation of Mencius' moral theory and that theory itself against alternative interpretive defences. I argue that the 'virtue ethics' reading of Mencius wrongly sees him as denying the distinction between moral philosophy and moral psychology. Virtue ethics is flawed, because it makes such a denial. But Mencius' moral theory, in spite of Mencius' obvious interest in moral psychology, does not have that flaw. However, I argue that Mencius is no rationalist. Instead, I show that he (...) upholds a coherentist moral theory, in which reason and psychology both have a role. The final third of the paper compares my interpretation with the work of various important Mencius scholars. I point out that the issue of the difference between moral philosophy and moral psychology is quite important in contemporary Western moral theory. (shrink)
