18世纪韩国代表实学者李瀷的心说

Abstract

The purpose of this study is clarify how Seongho Yi Ik fuses the mutually different world views and the mutually different critical minds between East and West. Seongho Yi Ik who had lived by having been locked in the Confucian world view and the Confucian critical mind based on the Confucian Classics had faced the Western religion and scientific thought. He had tried to understand the thought of East and West. Through a thesis titled “Yi Ik's Kyong Study´s(经学的) Backgrounds for his Acceptance of Western Learning”, the writer clarified that Seongho separated 'extension of knowledge(致知)' and 'investigating on things(格物)' in 'The theory on extension of knowledge by investigating on things(格物致知说). In Seongho's 'theory on extension of knowledge by investigating on things', 'investigating on things' means the investigation about objective-external facts, on the other hands 'extension of knowledge' means recognizing about subjective-internal practical value. In the midst of Seongho's new interpretation on The theory on extension of knowledge by investigating on things(格物致知说)' the critical mind of the fusion in the East-and-West thoughts can be read, which strives to integrate the empirically scientific thought in the West, which goes ahead of the East in the aspect of the objective fact awareness, and the more deeper Confucian thought in the aspect of the inside-oriented value awareness. Through this study, the writer aims to clarify that Seongho's this critical mind is already prepared in the midst of his 'Theory of Mind-Heart(心说)'. Seongho says that a human being's mind is what possesses simultaneously the ability, which can recognize on the objective fact world, and the moral ability, which can point to the life consistent with the origin of existence according to the inner principle. It means that a human being's mind has together the ability available for scientific awareness, and the ability avaliable for moral awareness. The ability of pointing to both sides, which the mind possesses, becomes not only the foundation that can integrate the Western world view and the East Asia's world view, but also the foundation of mentality that allows a human being to be able to understand together the inside and the outside of universal nature.
