Confucianism of the last period of Chosun was progressed towards two trends. One is disputes about the concepts of confucianism according to factional view point. The other is the tendency of practical science(實學) to search realistic solusion overcoming social conflict and political confusion. But despite of long-year dispute the concepts of confucianism were not defined. Despite of establishing theory of Bon-Che(本體論) based on the theory of Li-Ki(理氣論) problems still exist about how we could explain Bul-Sang-Ri(不相離) Bul-Sang-Jab(不相雜), and which the first is between Li(理) and Ki(氣). Theory of In-Seong(人性論) is based on the theory of Seong-Jeong(性情論), but the concept of Seong(性) is divided into Bon-Yeon-Chi-Seong(本然之性) and Ki-Jil-Chi-Seong(氣質之性), according to this a question arises whether the concept of Seong(性) is limited to humanbeing or reached to object. I think that it is necessary to clarify the authority of concepts and adjust them in order to solve these problems. They are what Seong(性) is in the theory of In-Mul-Seong Dong-I(人物性同異論), and whether Seong(性) and Li(理)have mutuality in the theory of Seong-Chuk-Li(性卽理). Seong-Li-Non-Byun(性理論辨) is a very useful work published by Lai-Hui Song(宋來熙) in the last period of Chosun. Lai-Hui Song intended to present the foundation of concepts, and to adjust concepts of confucianism of Chosun by compiling diverse articles and studies. Therefore the study on Seong-Li-Non-Byun(性理論辨) is useful to reform confusion between concepts on the theory of Sa-Dan Chil-Jeong(四端七情論) and the theory of In-Mul-Seong Dong-I(人物性同異論).
