Ji Kang's educational philosophy can be briefly divided into to two parts: one is overstepping the Confucian ethical standards, that is, criticizing secular ethical standards; the other is following nature, which is, promoting the educational values of free will. The ideas of “overstepping the Confucian ethical standards” and “following nature” supplement each other. They are not only characteristics of Ji Kang's age, but also profound studies of the educational theories of ancient China. The two ideas are especially used to have positive influence on how to foster the free development of individuality under feudalistic autocracy. In a word, Ji Kang's “overstepping the Confucian ethical standards and following nature” is a famous discourse in the history of Chinese educational philosophy.
