"This is the first comprehensive book-length study of the Yang Zhu figure, with respect to its appearances, expressions, and uses throughout the Chinese intellectual tradition. The studies in this book explore numerous strands and feelers that connect this figure with other Chinese thinkers and schools of thought, both those contemporaneous with 'Yang Zhu' as well as later emulators, thinkers, and critics. I believe this book is destined to become a standard reference in the field of Chinese philosophy and a must-have book for scholars of Daoism and related traditions." — Kirill O.
