 The Jin shu account cited above identifies the concept of wu as the locus of Xuanxue. The concept plays a critical role in the Laozi and has been translated variously as “nonbeing,” “nothing,” or “nothingness.” In classical Chinese, wu generally conveys the sense of “not having” something—e.g., “not having a name” (wu ming)—and functions as the opposite of “you,” “having” something. In the Laozi, it is used as an abstract noun as well. Specifically, the Laozi states that wu is the source of all beings (Chapter 40) and the basis of all functions (Chapter 11).
