tion of the classical texts, especially of the Book of Changes, and later on was chiefly instrumental in establishing the position of Tso's Commentary on the Spring and Autumn. He catalogued the Imperial Library, and in conjunction with his father discovered–some say compiled–the Chou Ritual.
A well-known figure in Chinese literature is Yang Hsiung (B.C. 53-A.D. 18). As a boy he was fond of straying from the beaten track and reading whatever he could lay his hands on. He stammered badly, and consequently gave much time to meditation. He propounded an ethical criterion occupying a middle place between those insisted upon by Mencius and by Hsün K'uang, teaching that the nature of man at birth is neither good nor evil, but a mixture of both, and that development in either direction depends wholly upon environment. In glorification of the Book of Changes he wrote the T'ai Hsüan Ching, and to emphasise the value of the Confucian Analects he produced a philosophical treatise known as the Fa Yen, both between A.D. 1 and 6. On completion of this last, his most famous work, a wealthy merchant of the province was so struck by its excellence that he offered to give 100,000 cash if his name should merely be mentioned in it. But Yang answered with scorn that a stag in a pen or an ox in a cage would not be more out of place than the name of a man with nothing but money to recommend him in the sacred pages of a book. Liu Hsin, however, sneeringly suggested that posterity would use Yang Hsiung's work to cover pickle-jars.
Besides composing some mediocre poetry, Yang Hsiung wrote on acupuncture, music, and philology.
