Sun Yat-sen said, “Besides reviving our ancient Chinese morality, we must also revive our wisdom and ability.... If today we want to revive our national spirit, we must revive not only the morality which is proper to us, but we must revive also our own knowledge.”(85) He goes on to say that the peculiar excellence of the ancient Chinese knowledge lay in the field of political philosophy, and states that the Chinese political philosophy surpassed the Western, at least in clearness. He quotes _The Great Learning_ for the summation, in a few words, of the highlights of this ancient Chinese social knowledge: “Investigate into things, attain the utmost knowledge, make the thoughts sincere, rectify the heart, cultivate the person, regulate the family, govern the country rightly, pacify the world.”(86) This is, as we have seen, what may be called the Confucian doctrine of ideological control. Sun Yat-sen lavished praise upon it. “Such a theory, so detailed, minute, and progressive, was neither discovered nor spoken of by any foreign political philosopher. It is a peculiar intellectual treasure pertaining to our political philosophy, which we must preserve.”(87) The endorsement is doubly significant. In the first place, it demonstrates the fact that Sun Yat-sen thought of himself as a rebuilder and not as a destroyer of the ancient Chinese culture, and the traditional methods of organization and control. In the second place, it points out that his Chinese background was most clear to him, and that he was in his own mind the transmitter of the Chinese heritage. In speaking of Chinese excellence in the field of the social science, Sun Yat-sen did not confine his discussion to any one time. Whenever he referred to a political theory, he mentioned its Chinese origin if it were one of those known to Chinese antiquity: anarchism, communism, democracy. He never attacked Chinese intellectual knowledge for being what it was, but only for what it omitted: physical science.(88) He was undoubtedly more conservative than many of his contemporaries, who were actually hostile to the inheritance. The summary of Sun Yat-sen’s beliefs and position in respect to the ancient intellectual knowledge is so well given by Tai Chi-tao that any other statement would almost have to verge on paraphrase.
