Han Fei was a central figure in Chinese Legalism, which was a leading school of thought in the Warring States period of China, and which left a huge imprint on political culture in imperial China. This article examines the complex duality of public and private interests in Han Fei’s political thought, a crucial aspect of his thinking. I argue that Han Fei adopted a sophisticated statist approach to understanding public and private interests. For Han Fei, public interests are embodied in (...) the state while private ones have dual functions. On the one hand, private interests threaten public ones by inviting corrupt material interests, personal morality, and knowledge, as well as human relationships. On the other hand, self-centered human psychology plays a dialectic role in strengthening the state. (shrink)
