This book is the first to engage Zen Buddhism philosophically on crucial issues from a perspective that is informed by the traditions of Western philosophy and religion. It focuses on one renowned Zen master, Huang Po, whose recorded sayings exemplify the spirit of the "golden age" of Zen in medieval China, and on the transmission of these writings to the West. While deeply sympathetic to the Zen tradition, it raises serious questions about the kinds of claims that can be made on its behalf.
