Sung Hsing also called Sung Tzu (c.360–290 . .), Chinese philosopher associated with Mohism and the Huang–Lao school. He was a member of the Chi-hsia Academy of Ch’i, a late Warring States center that attracted intellectuals of every persuasion. His Mohist ideas include an emphasis on utility, thrift, meritocracy, and a reluctance to wage war. He is praised by the Taoist Chuang Tzu for his beliefs that one’s essential desires and needs are few and that one should heed internal cultivation rather than social judgments. The combination of internal tranquillity and political activism is characteristic of Huang–Lao thought. See also MOHISM. R.P.P. & R.T.A.
