心與氣在《莊子》中作為重要的哲學範疇當無疑義，學界也對之多所討論。不過，心與氣的關係為何，不但對《莊子》而言同為重要的問題，並且也還有進一步釐析的空間。本文嘗試論證，《莊子》的心氣關係，包含了活動機制上的心氣交涉，以及修養層面的心氣交養，而前者是後者的基礎。從這兩個面向可以看出：「心」在《莊子》中是修養實踐的動力機制，但是必須有著氣的能力的交養，方能使心的實踐動力展現完善的倫理性而避免內在性的封閉。本文將先就《莊子》心的相關意涵進行分析，並以此為基礎，進一步就心氣關係的相關面向進行闡釋。

There have been a lot of researches about Xin and Ci, two important philosophical concepts in the Zhuangzi, and the relationship between the two also deserves our attention not only because it is an important issue in studying the Zhuangzi but because there is still some obscurity in the relationship we need to ponder over it more and in detail. The paper tries to clarify the important interaction between the two from two dimensions; one starts from the interaction in terms of mechanism of activities, and the other explores from the aspect of cultivation to think over the interaction between the spiritual cultivation and the one of Ci. Undoubtedly, the interaction in the mechanism of activities is the basis of the one in cultivation dimension. With the meditation from the two dimensions, it discloses that Xin plays the role as mechanism of motivation in one’s cultivation; however, without the interaction with Ci, it is difficult for Xin to fulfill ethics in its mechanism instead of being limited in itself. Therefore, the paper focuses first on the possible implications of Xin in the Zhuangzi and then goes further to discuss the complicated relationship between Xin and Ci.
