『외암유고』의 편찬 과정과 판본의 특징

Abstract

This article surveys the various published versions and the development of Oeam yugo (巍巖遺稿), written by Yi Gan (李柬:巍巖, 1677~1727) who belonged to a Yulgok School's Kwon Sangha (權尙夏) branch. Yi Gan was a colleague of Han Wonjin (韓元震) and Choi Jinghu (崔徵厚), discussing important concepts of Confucianism such as bonyeon-gijil (本然․氣質), mibalsimchae (未發心體), heoryeongjigak (虛靈知覺), and myeongdeok (明德) with them, thus having major repercussion in the contemporary Chosun academia. He stuck to his opinion which differed from Han Wonjin as well as his mentor Kwon Sangha, and gained supports from scholars in Seoul - represented by Kim Changhyup (金昌協) and his disciples. Combined with those supports, the debate can be estimated as a nodal point of the divergence between Hohak School (湖學派) and Rakhak School (洛學派). The above situations gave difficulties to the editing and publishing of Yi Gan's posthumous work, Oeam Yugo. Being edited by his son Yi Yibyeong(李頤炳), the work had to face opposition from Yi Gan's colleague Yun Bonggu (尹鳳九) at the time of its original publication. Yun's claim was that the work was insulting his mentor Kwon Sangha which should be revised, and his claim created a stir in Kown Sangha branch. Yi Yibyeong, however, not only adopted the oppositional claims of Yun Bonggu but also strengthened the parts in question. This incident was a reflection of conflicts within Hohak School brought about by Kwon Sangha's intervention in the debate between Yi Gan and Han Wonjin. Passing through such conflicts, original version and revised version of Oeam Yugo were published, being respectively consisted of eight volumes with sixteen chapters; of which, the revised version being currently in circulation. Differences between the original and the revised version are not so conspicuous, the latter adding four pages respectively in two places. In the process of writing this article, the author found that another hitherto unknown version exists and that it contains much more contents the two versions in different structure from the two. Further study is called for the newly found version of Oeam Yugo.
