율곡학파의 리기론

Abstract

This thesis is focused on analysis and understanding of LiKi by Yulgok school. The subject of this thesis is the understanding of LiKi, from 16th century to 18th century. Specifically, this thesis analyzes the understandings of Yulgok Lee I, and his indisputable disciples, Wooam Song Si-yeol, Suam Kwon Sangha and Namdang Han Wonjin. First, this thesis analyzes Yulgok's understanding of LiKi and how his disciples made depth in his understanding. Yulgok school could diversify and deepen the understanding of LiKi in various angles, based on Yulgok's understanding. Also, this resulted not only in development of Theory of LiKi but also in advance of Theory of XinXing. Yulgok and his disciples confess that it is difficult to understand and explain LiKi. This is drawn from neo-confucian dilemma of Li and Ki being one but two, and two but one at the same time. Yet, they approached LiKi in various angles, subdivided and analyzed LiKi to explain this dilemma. In Yulgok school's understanding of LiKi, zhuli and zhuqi are only one part of fragmented understandings. Through this, it could be confirmed that Toegye school's diagram of dialectic conflict between chuli(主理, principle(li) as the predominant factor) and chuki(主氣, materail force(ki) as the predominant factor) is only available in restrictive understanding.
