膠宇 尹冑夏의 학문연원과 사상경향

Abstract

This paper is aimed to shed light on Yun Jooha's academic source, his study of li (理), and his attitude towards reality. Yun learned under scholars like Jang Bokchu, Heo Jun, and Yi Jinsang. As a pupil of Heo Jun, he learned study of propriety and li and let his learning of propriety be practiced in Geochang. Yun also wrote holgi (笏記), a guide of propriety, and legislated it for every rituals. As a pupil of Yi Jinsang, Yun practiced study of li. Since Yi's theory of the mind as principle was treated heretical among Yeongnam based scholars, Yun wrote「Bangurok」 in defense of Yi's theory of li. Under Yi's influence, Yun argued that although dispositions are existent in the mind before it is aroused, they can be said as non-existent because they are not yet affected. At that time, many scholars like Jang Bokchu and Kwak Jongseok were opposed to Yun's idea. Yun argued that one in an official position should be able to sacrifice for country, and one in a non-official position should be able to sacrifice for tao. Yun sent a reproaching letter to Kwak Jongseok who let his pupils attend to current social and political affairs, study foreign learnings. Yun kept a principle that study of li should be more deeply learned and protected to overcome hard times of history, and he devoted his lifetime to study of li.
