한국철학 : 성호(星湖) 성리설(性理說)의 전개와 변용 = Expansion and Transformation of Sung-Ho`s Sungli-sul(性理說)

다국어 초록 (Multilingual Abstract)

This is a study to disclose the characteristic of Lee Ik(李瀷; Sung-Ho星湖)`s theory of Sungli(性理說). In order to prove my claim above, I classified it into theory of Mind(心性論) and theory of Cosmos(宇宙論), and inquired into the characteristics of them respectively. So first I considered Sungli philosophy(性理學) as metaphysics of Li(理) that is a priori and moral, and considered Practical science(實學) as studies of a phenomenon that is empirical and positive. hereby I decided the characteristic of his theory of Mind(心性論) and theory of Cosmos(宇宙論) in the body of a thesis. Depending on the above argument, Lee Ik`s theory of Sungli is characterized by the following features. In the theory of Mind(心性論) he succeeded to Lee Hwang`s theory. So he affirmed `the activity of Li(理)`, and asserted that seven feelings(七情) and four moral feelings(四端) are different in original character. Furthermore he reorganized Lee Hwang`s theory of Mind into an extreme moral theory, therefore he argued that not only four moral feelings but also seven feelings are the same originated from Li(理). This is called the doctrine of Li-Fa-Yi-Yuan(理發一原說). Such feature can be estimated as the feature of moral monism in his theory of Mind. So his theory of Mind has the characteristic of Sungli philosophy(性理學) rather than the characteristic of Practical science. In the theory of Cosmos(宇宙論), he insisted on a world view of Juri-Ron(主理論) that thinks relatively much of Li in his early years. Later he insisted on a world view of Juqi-Ron(主氣論) that thinks relatively much of Qi. And in his later years he again insisted on a world view of Qi-Xue(氣學) that regards Qi as the ultimate. Therefore such process as that was a development of his theory of Cosmos, from the world view of Sungli philosophy(性理學) to the world view of Practical science. In conclusion, the characteristic of Lee Ik`s theory of Sungli is a conspicuous discordance between the theory of Mind and the theory of Cosmos. That is the discordance between the moral and metaphysical characteristic of the theory of Mind and the experiential and positive characteristic of the theory of Cosmos. Hence Lee Ik`s theory of Sungli does not have a consistent philosophical principle.
