兩宋 太極論 전개에서 程頤 ‘理’論의 위상 - 太極에서 理로

Abstract

Neo-Confucianists in the Sung Dynasty period tried to establish the basic Confucian morality by disclosing the ontological origin of the universe and that it is the source in the value · existence of man and society. The center of such an attempt is the very 'Taeguek(太極)' theory, the completion of which was made by Zhu-hi(朱熹) in southern-sung Dynasty period. However, Cheng-yi(程頤), which played an essential part in Confucian philosophy in Sung Dynasty period, has not used a concept Taeguek even once. The concept was referred just once in 「A preface of the Change(易序)」 of 『Cheng-yi's interpretation of the Change(程氏易傳)』 in existence, but which is also considered to be not his work but to be a work written by Zhu-heaggi(周行己), his disciple. Jeongi seems to have understood Zhu-donyi(周敦頤)‘s concept of Taeguek as Gi(氣). As if he criticizes Zhangz-jea(張載)’s concept of Taeguek, he did not accept Zhu-donyi‘s concept of Taekguek and instead of that, proposed ‘Li(理)’ concept. Li is the Principle(所以然) from the existence viewpoints and the Ought(所當然) from the value viewpoints. Such Li concept of Cheng-yi was succeeded to Zhi-hi as it is, resulting in being connected to Zhu-donyi's concept Teaguek. Accordingly, it can be said that though Jeongi did not use concept Taeguek, the attempt that tried to establish the basis of Confucian morality, by connecting the existence and value of Neo-confucianists in the Sung Dynasty period, is regarded as very important.
