이황과 이이의 우주론과 인성론 비교 정리

다국어 초록 (Multilingual Abstract)

In this comparative study of cosmology and ethology of Yi Hwang and Yi I, founders of the two Korean Neo-Confucian schools of li or principle and ki or material force, I try to clarify their different positions in the usage of the concepts of li and ki, two cosmological substances, which lead in turn their differences in theory and in practice. For the purpose, I begin with an examination of the cosmology of Tchou Hi, founder of Chinese Neo-Confucianism, in which he uses the concept of li in contradictory way. This contradiction brings about different understandings of the concept and, as a result, different cosmology and ethology for the two Korean Neo-Confucianists. Yi Hwang admits activity of li and ki. From this point of view, he constructs his idealistic cosmology and rationalistic philosophy. Yi I admits activity of ki, but denies activity of li. And this point of view leads him to construct his cosmology and philosophy declined with materialistic and empirical tendencies, respectively.
