유중교는 왜 이항로의 심설을 조보(調補)했는가?

Abstract

This paper presents an investigation into why Yoo Joong-gyo adjusted and supplemented the theory of the mind by his teacher. Inside the Hwaseo School, there were disputes between Kim Pyeong-muk and Yoo Joong-gyo due to the latter’s attempt at adjusting and supplementing Lee Hangro's theory of the mind. Kim pointed out that Yoo misunderstood their teacher's theory of the mind and refuted him again, which led to the arguments over the theory of the mind in the school. In the interpretations of the mind and the bright virtue based on the theory of Li and Qi, Yoo pointed out that one could talk about the bright virtue principally to Li but might face problems with talking about the mind principally to Li. The main reason that he tried to adjust and supplement Lee's theory of the mind was to establish the legitimacy of Chosun's Neo-Confucianism with the theory of his school. Lee’s way of explaining the mind mainly based on Li could be misunderstood to be the same as that of the Learning of Yangming. This misunderstanding might be a serious blow to the academic legitimacy of their school. As a matter of fact, this misunderstanding was raised continuously by the Ganjae School, which was the biggest group of literary people in the late of the Chosun. Yoo thus decided to provide active explanations about this misunderstanding that could be caused by his teacher's theory of the mind based on the theory. He made a clear distinction in nature as a rule of the mind in order to put an emphasis on the practicality of the mind. According to him, when the mind performs its main business, it can be the realization of Li’s Jujae(主宰). In this case, the mind can be called principally to Li. It is certain that the realization of moral good by the mind is eventually the Jujae outcome of Qi by Li, which allows for explaining the mind principally to Li.
