鳳棲 俞莘煥의 未發論 연구

Abstract

Mibal(weifa, being risen yet, 未發) discourse, one of the core propositions of self-cultivation theory related to moral practice in Neo-Confucianism, was one of the core arguments of Chosun Neo-Confucianism. In the Kiho academic world, after the debate between Yulgok(栗谷) and Ugye(牛溪) on the issue of good and evil in Mibal, various discussions have been developed around Mibal. In particular, throughout the 18th century, discussions on Mibal revealed various controversies, and discussions on Mibal continued until the first half of the 19th century without reaching a clear consensus. Bongseo(鳳棲) Yu Shin-hwan(俞莘煥, 1801~1859), a representative scholar of the 19th century KIho Nakron(畿湖 洛論), tried to establish a realistic basis for moral practice through discussions on Mibal. And he summarized the Mibal issues until then into three categories: 1) the presence or absence of an ordinary person's Mibal, 2) the same and different between an sage and an ordinary person's Mibal, and 3) the depth and shallowness of the Mibal. And he examined Zhu Xi’s theory in various ways and presented his opinion in detail. In this paper, I tried to summarize and analyze Yu Shin-hwan's Mibal theory, focusing on his Mibalseol(未發說). In Mibalseol, not only the Mibal issues of the Kiho academic community developed until that time, but also the theory of Zhu Xi as the basis for claims related to each issue. By paying attention to this point, I tried to summarize Yu Shin-hwan's understanding of Zhu Xi’s theory and his views on each issue presented through it. In addition, I tried to confirm the characteristics of Yu Shin-hwan's Mibal theory in connection with the issue of Mibal theory and to present the significance of his Mibal theory.
