화담 서경덕의 『황극경세서(皇極經世書)』 이해 − 「성음해(聲音解)」와 「황극경세수해(皇極經世數解)」를 중심으로 −

Abstract

This paper examines Seo Gyeong-Deok(徐敬德)'s Huanggijingshishu(『皇極經世書』) through “Sungumhai”(「聲音解」)⋅“Baljeonsungumhaimichincheo”(「跋前聲音解未盡處」) and “Hwanggeukgyeongseuhae”(「皇極經世數解」). It examines understanding. In 1426, Xinglidaquan(『性理大全』) was imported from China, but due to the difficulty of Huanggijingshishu, it was difficult to understand other books included in Xinglidaquan. Accordingly, the person who helped in understanding Huanggijingshishu was Seo Gyeong-Deok. However, through understanding Huanggijingshishu, Seo Gyeong-Deok came to be misunderstood by people at the time as a mathematician, although he did not intend to do so. Through the “Preface”(「序文」) of the intermediate version Hwadamjip(『花潭集』), it can be seen that Seo Gyeong-Deok is an outstanding Neo-Confucian scholar, but he is also an outstanding scholar mathematically through his understanding of Huanggijingshishu. Only by combining these two facts can we properly understand Seo Gyeong-Deok. Xinglidaquan(『性理大全』) this version of Huanggijingshishu has “Chandojiyo” (「纂圖指要」), which summarizes the entire contents of Huanggijingshishu. Seo Gyeong-Deok's “Sungumhai”⋅“Baljeonsungumhaimichincheo”, “Hwanggeukgyeongseuhae”, and “Yuksibsagwaebangwonjidohae” (「六十四卦方圓圖解」) are selected and explained contents of “Chandojiyo”. In addition, based on “Sungumhai” and “Hwanggeukgyeongseuhae”, it became the basis for a new understanding of Hunminjeongeum(『訓民正音』) in the late Joseon Dynasty and a new understanding of Western astronomy from the perspective of epidemiology. Seo Gyeong-Deok is a famous Neo-Confucian scholar. In order to properly understand Seo Gyeong-Deok, the meaning of the Huanggijingshishu he expounded is not Zhu Xi(朱熹)'s thoughts contained in Sishudaquan(『四書大全』)⋅Wujingdaquan(『五經大全』), but the ideas of Zhu Xi along with Zhu Xi(朱熹). It is important to know that it was Xinglidaquan, which contained the thoughts of various figures during the Northern Song Dynasty.
