「樂」，是人們的重要追求之一，在中國思想史中也具有相當多值得研究的內容。留給後人鮮明之快樂形象的《莊子》，其所談的「至樂無樂」是關於「樂」的著名論述。本研究以「至樂無樂」等《莊子》論「樂」之主要文獻的解為基礎，對於《 莊子》 關於「樂」的思想做一探究，了解到「喜好意向」為《 莊子》 論「樂」之主要且具有特色之意涵，而所謂「至樂無樂」乃是「最高的喜好意向是沒有喜好意向」。此與《莊子》所強調的「無為」，具有一圓的理路，亦是體道的一種呈現。但「樂」與「逍遙」的關係，從逍遙所蘊含的自由等基本意涵來看，無喜好意向而不受制於外約的「至樂」，可以說是遙」之不同面向的陳述。

Le 樂， or “happiness, “ is one of the most important things that people strive for in the search for meaning in their lives. In the history of Chinese philosophical thought, essays on le are plentiful. In Zhuangzi莊子, zhile wule至樂無樂 is a famous discourse. Based on an analysis of the relevant passages regarding le in Zhuangzi, this article seeks to point out that “intention of like or desire” is the most significant and characteristic principle, and zhile wule means “the highest level of intention is no intention” －a manifestation of wuwei無為and dao道, or the “Way.” As for the relationship between le and xiaoyao逍遙, considering the freedom and other basic meanings of xiaoyao, it is conceivable that zhile－being free from dependence on external objects－is yet another description of xiaoyao.
