Takahashi-Doru(1878∼1967), Japanese scholar, was first scholar to divide into the Juripa(主理派) and the Jugipa(主氣派) on the history of Confucianism in Chosun Dynasty. He aimed to combine the argument of Chosun confucian scholars and political faction, and to make the factionalism in Chosun Dynasty. He intensionally remove off the Simseolnonpyon, which was the characterist of Chosun Confucianism Nevertheless, his argument still is accepted in the text and the popular books. But now days, Korean scholars criticized the Takahashi's understanding. They doubted Takahashi's understanding of the Jugipa in the history of Confucianism in the Chosun Dynasty. And they insist that Takahashi wanted to emphasize political faction. Yi hang-ro(1792∼1868) is a good case. It proved that Takahasi'theory was wrong. Facing a difficult situation of West Imperialist invade, Yi stressed Lijongibi(理尊氣卑), made his doctrine of Simjurisol(心主理說), the theory of the primacy of Li in the mind. While setting forth Simhapligi(心合理氣) as a premise, he took a view point of Bonsimjeukli(本心卽理). When observing that Simjurisol(心主理說) of Yi was specialized within Noron(老論) which derived from Yi I, we can know Takahasi-Doru(高橋亨)'s recognition was wrong. Takahasi insisted that theories was in accord with parties, therefor struggles of parties was ceaselessly in Chosun Dynasty. But Simjurisol(心主理說) of Yi is a good example showing that there were many different doctrines within same party, especially Noron(老論). And Simgyeomligisol(心兼理氣說), which was the theoretical background of Yi's Simjurisol(心主理說), is also excellent instance indicating that Takahasi's classification of Juripa(主理派) and Jugipa(主氣派) was incorrect. This study aims to arrange the Takahashi's research and analysis for the history of confucianism in Chosun Dynasty and later korean scolars' critique on Takahashi's theory.
