“Gewu Zhizhi” is the core of Zhu Xi’s “Gongfu” theory; however, it is insufficient to interpret via scientific logic system, because by doing so there will be some contradictory flaws unavoidable. However, if we return to the original discourse of Zhu Xi, we will find his “Gewu Zhizhi” is self-content within its inner principle, totally different from our contemporary “knowledge” system. Therefore, this proposal will provide a new way to discuss “Gewu Zhizhi”: detaching it from the pure scientific view and putting it into the contexts of Zhu Xi’s own intellectual world. Then, we can avoid the superficial explanation about the “paradox” of “Gewu Zhizhi”. In other words, this proposal will try to enter the inner logic of Zhu Xi’s “Gewu Zhizhi”, hope to disclose its original thought, its Oriental philosophical characteristics, and its extending influences on the “knowledge system” in East-Asian from Ming dynasty to the present.
