The classic period of Chinese philosophy covers about three hundred years, from 550 to 250 B.C. Chuang Tzu, the greatest of the Taoist writers whose historical existence can be verified (we cannot be sure of Lao Tzu), flourished toward the end of this period, and indeed the last chapter of the Chuang Tzu book (Chap. 33) is a witty and informative history of Chinese philosophy up to his time—the first document of its kind, at least in the Orient.
