Kang-You-Wei who took the lead in the Wu-Xu political change at the close of Qing Dynasty had greatly contributed to ushering in a new epoch of Chinese modernization as a man of both political ideas and Confucianism. The purpose of this paper is to clarify his Confucian ideas through a comprehensive research of his predecessors who had influenced him in his theorization and his major publications. There are three scholars who had exercised a decisive influence upon his theorization. Zhu Ci-Qi laid the foundation of his theories and fosteied his graceful and virtuous personality. Liao Ping suggested the way for the development of his Confucian theories into political ideas, thus it might he said that his later publications are nothing but the systematization of Lao``s theories. Lastly, Zhang Yan-Qiu enlarged his acquaintance with the historical development of modern times and the issues of the day. Of his copious writings Xin-Xue-Wei-Jing-Kao and Kong-Zi-Gai-Zhi-Kao are the most important works. Through these two works lie presented his own theories for a new interpietation of the Classical Canon. He ranked Confucius as an absolute sage, and at the same time he maintained that the social institutions be reformed in accordance with the current of the times, as Cofucius did. Lang Qi-Chao, his disciple, compared him to a whirlwind, a volcanic eruption and an earthquake because of his notable contiibution to the academic world, while his theories were so dogmatic and absuid that the gicat impact on the orthodox Confucians led to their counterattacks. What is most important in interpreting his theories is from which angle they are viewed; he can be a great Confucian, a man of political ideas, a religionist or an anthropologist depending on one``s viewpoints. 1-lowever, it is obviously true that his theorization was not so much for the sake of Confucian study as for the reformation and idealization of human society. In other words, it was for the puipose of justfying his own political ideas that he had ipursued inquiries into the Classical Canon, which resulted in so dogmatic an interpretation of the Classical Canon and the absurd theorization.
