本文從莊子的「一氣論」、陰陽之氣以及虛靜之精神境界三個向度來考察莊子「氣」論思想，藉爬梳莊子學當中，「氣」所隱含的內在意義，並且透過「氣」之釐析，彰顯出「遊」所以可能的依據，邁立起由「氣」到「遊」之理論架構。

Chi is a very important conception in Chuang Tzu’s philosophy. It is not only an actual substance indwelling Things, but also an intermedium between Tao and Things. It has metaphysical and physical characters. Because of the dual characters, Chi has the basis on leveling all things and offers men the possibility to freedom. In the following paper, three important issues will be discussed. Firstly, “One-Chi-Lun”: it means the origin of Chi not separated. Secondly. “Chi of Yin-Yang”: it is the dynamic substance. Thirdly, the contemplative spirit. The three parts are linked together as an organic allness. Chuang Tzu didn’t consider Chi an isolate object, but regarded that it could penetrate T’ien, Earth, and Man. Hence, through the practice of fasting of the heart, man can emancipate himself form any restrictions and ramble in the realm of the Infinite.
