霞谷 鄭齊斗의 人物性異論 硏究 -知覺說을 中心으로

Abstract

How did Jeong, Je-du(鄭齊斗, 1649-1736, the honorific name: Ha-Kok) a scholar of Yang-ming school, criticize Zhu Xi(朱熹)‘s theory of Gewu-zhizhi(格物致知; Principles of completing knowledge through thing's li) and accept Wang, Yang-ming(陽明)'s Xinjili(心卽理; human nature is directly li) principle in the late Choseon dynasty's social contexts being the orthodox Neo-Confucianism? He thought Zhu Xi‘s theory, getting knowledge through thing's li is not utility of getting my heart's li. Also he criticized Yang-ming school’s a problem Tian li(天理)'s subjectivity. Thus Jeong interested argument of difference between man's nature(人性) and thing's nature(物性) on Korean Neo-Confucianism in the late Choseon dynasty In this paper, I researched Jeong's philosophical thoughts related views of difference between man's nature(人性) and thing's nature(物性). From the forties to the fifties, Jeong disputed with Min, Yi-seung(閔以升, 1649-1698, the honorific name: Seung-jae), gave and returned letters. In these letters I can find Jeong's views about 'man's & thing's nature' and Zhijue(知覺; perception for li) & Zhi(智; wisdom) Jeong agreed to discuss Zhijue(知覺) with Zhi(智), analyzed difference between Zhijue and Zhi and related Zhijue, Zhi with items of 'Thing's li(物理)', 'Active li(生理)', 'True li(眞理=Tian li)'. He recognized Zhijue, 'perception for li' to be the Active li(生理). The Active li is not only power of human life but also perception for morality. In contrast, he admitted trees, animals, and so on having power of life, possibility of Active li, but that can't make true their Active li to be True li(眞理). On distinguishing 'Active li' from 'Thing's li', he explained man's nature different from thing's nature. Also on distinguishing 'True li 'from Active li', he suggested holy man's nature different from man's nature.
