It is said to be that most part of Seo-in(西人) scholars (e.g. Song, Si-yeol(宋時烈) and his pupils) regarded Neo-Confucianism(朱子學) as the absolute one, and only admitted it for their orthodoxy. In contrast, however, there was a bunch of scholars who tried to accept Neo-Confucianism critically participating in Seo-in party such as Jo, ik(趙翼), Choi, Yu-hae(崔有海), Choi, Yu-Ji In terms of this viewpoint, I focused on the fact that Gan-ho(艮湖) Choi, Yu-Ji(崔攸之) had revised the book of "Dae-hak-jang-gu"(『大學章句』), and studied his revised contents and its significance to this paper. Gan-ho's revision on " Dae-hak-jang-gu" proofread by Chu-tzu(朱熹:1130-1200) are summarized as follows; (1) Gan-ho regarded next two chapters of 'mul-yu-bon-mal(物有本末)……' and 'gi-bon-ran-yi-mi-chi-ja(基本亂而末治者)……' included in the major text(經) as the explanation of 'Gyeok-mul(格物)', so remade it into the 4th chapter of the minor text(傳) combining with the chapter of 'Cheong-song(聽訟章)' (2) Gan-ho regarded next two chapters of 'ji-ji-yi-hy-yu-jeong(知止而后有定)……' included in the major text and 'gi-bon-ran-yi-mi-chi-ja(基本亂而末治者)……' included in the 5th chapter of the minor text as the explanation of 'Chi-ji(致知)', so remade it into the 5th chapter of the minor text combining the two chapters. The significance of revision on the book of "Dae-hak-jang-gu" by Gan-ho can be valued as follows; (1) Several Seo-in scholars had succeeded progressively traditional scholarship without falling in the trap of adhesion under highly 'Neo-Confucianism dominated circumstance'. (2) Gan-ho had revised some part of "Dae-hak-jang-gu" with his trailblazing viewpoint based on the peculiar studying method mentioned above. (3) Gan-ho had succeeded and developed the former theories digestion well enough advocated by Dong, Goi(董槐) and Gueon, Geun(權近) (4) The separation of the two chapter of 'Gyeok-mul' and 'Chi-ji' from Chu-tzu's "Dae-hak-jang-gu" by Gan-go is outstanding opinion never found on former theories. In interpretation history of "Dae-hak", therefore, it must be valued to quite a new theory that no one had ever mentioned before.
