The focus of this paper is on analyzing the concept of an 安 (contentment) in relation to the two key concepts in the Zhuangzi, ming 命 (uncontrollable situations) and xing 性 (nature). I argue that the attitude of acceptance in the Zhuangzi can be abstracted from the concept of an when confronted with human limitations, as seen through the related concepts of ming and xing. In order to present the above arguments, this paper will be arranged in the following way: first, the connotations of xing and ming will be reexamined and new understandings of the concepts will be proposed. Second, the idea of an in relation to xing and ming in the Zhuangzi will be elaborated upon. Last, but not least, I present a discussion of how the “Zhuangzian” perspective of acceptance, which can be extracted from the idea of an, differs from the concept of acceptance in the Western philosophical tradition more broadly.
