Abstract
Similarities between Daoism and Chan (Zen) are often merely verbal, a skillful appropriation by Chan authors of a vocabulary that seems Daoist only to a point, and then departs in a predictable way. What makes the departure predictable is the completely different understanding of emptiness in Chan and Daoism, supporting a no less different understanding of the value of knowledge. Daoism remains optimistic about knowledge in a way Chan is not. Buddhist wisdom exhausts life, extinguishes it, does not nourish it, and therefore cannot satisfy the Daoist conviction concerning the value of knowledge.
