This paper is meant to confirm the philosophical implications of Zhuang Zi's ideal of “making all things equal” through conducting a contextual analysis of the text of Zhuang Zi. In the meantime, it's also intended to re-construct the relationship between “tao” and “things” and further consider the specific ideas of the doctrine of “tao and things combined into one” from Zhuang Zi's philosophy of making all things equal so as to avoid any misinterpretations that might be made by applying contemporary abstract thinking to Zhuang's philosophy. Also, we try to make another profound reflection on the “closed system” constructed by the logics of language, by means of criticizing Zhuang Zi's theoretical thinking as well as his approximately existential experience of “situation ethics.” Consequently, we still have to inquire whether the thesis of “tao and things combined into one” is a metaphysical proposition, if tao and things can be combined into one, and how they can or cannot be combined.
