The main thread of Feng Qi's philosophy is his doctrine of wisdom. In his solution to the problem of wisdom, however, he advocates a kind of broad-sense, general epistemology that is of great significance. Precisely because of his construction of such an epistemological system, Feng Qi makes a totally fresh understanding and definition of the wisdom problem, and sets up a distinct philosophical sys-tem featuring his doctrine of wisdom. This paper makes a few analyses of Feng Qi's thoughts from the construction of broad-sense epistemology and its penetration into the doctrine of wisdom about human na-ture and the Way of Heaven, so as to further grasp the built-in spirit of Feng's philosophical system.
