In this paper, we elucidate the moral psychology and what we might call the moral sociology of Mencius and of Hume, and we argue for three claims. First, we demonstrate that there are strong similarities between Mencius and Hume concerning some of the principal psychological sources of the virtue of humanity. Second, we show that there are strong similarities between the two concerning some of the principal social sources of the virtue of humanity. Third, we argue that there are related, (...) though weaker, similarities between Mencius and Hume concerning some of the principal cognitive sources of the virtue of humanity. We conclude by suggesting that the number and nature of these similarities demonstrate the need for future research on the conceptual connections between Confucian and Humean moral philosophy, especially on the psychological and social sources of benevolent moral development.
