Yang Hsiung (53 B.C. – A.D. 18), Chinese philosopher who wrote two books: Tai-hsüan ching (‘Classic of the Supremely Profound Principle’), an imitation of the I-Ching, and Fa-yen (‘Model Sayings’), an imitation of the Analects. The former was ignored by his contemporaries, but the latter was quite popular in his time. His thoughts were eclectic. He was the first in the history of Chinese thought to advance the doctrine of human nature as a mixture of good and evil in order to avoid the extremes of Mencius and Hsün Tzu.
