"Philosophically it is more sophisticated than any other English-language work on Xunzi. The Tian Lun Pian is one of the most important of Xunzi's writings, and whereas other scholars give us a menu, Machle gives us the meal. The translation is accurate; the prose limpid; and the commentary is philosophically superior in every way to the others." — Henry Rosemont, Jr., St. Mary's College of Maryland
