東武 李濟馬의 性情論에 대한 해석- 四七理氣論辯을 중심으로 -

Abstract

Li Je-Ma who established Sa-sang constitutional medicine, at the close of Joseon Dynasty suggested new viewpoint of Human being through analyzing man's properties of four elements namely relation, mind, body and matter which constitute the cosmos. In the fields of time and space, consists of universal system and social relations, and in lives of nature and mission, he has set existence of human being to grasp an aspect of changes of mind and body. Four kinds of Sa-sang constitutions are just the results of this like discernment. The reason that the expression of emotional nature can be possible, is that, if Four clues of ethics must be included in seven emotion's category that are combinations of principal and Gi, anymore the name of Four Clues is not necessary, and the expression just corresponds to control of emotions, that is to say, revelation of emotions. He tried to study on nature of human being through grasping the changes of emotions, that are easily recognized in the reality, for being bound to formal names of Four Clues. Liking and disliking emotions, especially liking goodness that he layed weight on, is based on the initial and pure recognizing of human being, as essentially related to traditional ethical doctrine of innate goodness. By the reason above mentioned, he taking a serious view of emotions, inclined to Gi Deaseung than Lee Hwang. But through investigation of emotional revelations to the degree of Human nature, it is not one that has passive meaning of waiting for combination with Gi, but get changed to another positive one that constantly response to external existence, thus essential nature of human being regained the position making self awareness and practice, being correspond to the idea of Lee Hwang.
