凝窩 李源祚와 后山 許愈의 四端七情論 비교 고찰

Abstract

This paper is a comparative study of the sadanchiljeong theory of Eungwa(Lee Won-jo, 1792-1871) and Husan(Hu Yu, 1833-1904), a member of the Toegye school that was active in the 19th century. Eungwa and Husan have an orthodox connection with the Toegye school group; also, the relationship between uncle(Eungwa) and disciple(Husan) is established around Hanju. If Eungwa influenced the study of Hanju, who is his nephew, and Hanju in turn influenced his student Husan, in the end, their theories should not be much different. But their theory of sadanchiljeong show clear differences. While Eungwa emphasizes Chiljeong's kibal(氣發), Husan's focus is on Chiljeong's libal(理發). Meanwhile, the theory of sadanchiljeong by the Toegye school of the 19th century is characterized by its development around the content of chiljeong. For example, whether to look at chiljeong through the perspective of libal or a kibal is a prime example. According to sadan/libal and chiljeong/kibal, which are the key aspects of the theory of sadanchiljeong of toegye, chiljeong should be a kibal. However, based on the proposition of 'sengbalweijeong(性發爲情)', not only sadan, but also chiljeong should be libal because it reveals true nature. Also, both sadan/libal and chiljeong/kibal can easily be interpreted as an evil spirit. For this reason, the theory of sadanchiljeong of the 19th century Toegye school mainly focused on the question of whether chiljeong should be a libal or a kibal. Thus, the text shows the theoretical differences between the two men's sadanchiljeong theory. Through interpretation of their views, the division of the late 19th-century Toegye school of the sadanchiljeong will be considered in addition to its contents.
