『삼현수간(三賢手簡)』에 나타난 우계의 ‘사단⋅부중절’ 문제에 대한 연구

Abstract

The purpose of this paper is to consider the issue of ‘四端 不中節' of the dominant sex marriage. In response to the four complex theory that appeared in Ugye's letter to Gubong in 1560, I would like to consider the idea of the ’ ‘四端 不中節‘in Ugye's philosophy and the argumentation of Toegye, Gobong, and Yulgok. This issue has been the subject of debate among Confucian scholars since the Joseon Dynasty, when Gobong raised the issue of the ’四端‘ in a letter to Toegye, rather than the period of Juja. At the heart of this issue is how to understand the status of the ’四端‘ and how it can become a sub-interrogation. In a letter to Gubong, Ugye points out that scholars only cite Zhu Xi's theory and say that it is always correct without their own theory, and speaks of the concept and standard of his theory. Through this approach, I would like to analyze the concept of '四端 不中節’ in the hierarchy and study its philosophical implications.
