"This book contains an enormous amount of information concerning all aspects of T'ai-chi ch'uan not available before. To say that the work is a major contribution to the field is an understatement; it dwarfs all other works so far published in the English language. This is a first-rate, scholarly book that will have a great bearing on the academic views concerning T'ai-chi ch'uan's history and value for present-day study. Because of his meticulous research and profoundly articulate text, Wile has redefined 'T'ai-chi ch'uan' for the academic world with clarity and, for the first time, with accuracy." — Michael A. DeMarco, Journal of Asian Martial Arts
