성리학과 서학의 공존: 다산 정약용의 사칠설

Abstract

The purpose of this paper is to analyze Dasan's “Four-Seven” theory in detail, and to examine the existing viewpoint that his heterogeneous viewpoint originated from Tianzhushiyi. Dasan's method of reading the “Four-Seven” theory has attracted the attention of several researchers since the 1990s. Some researchers emphasized the influence of Seohak, while others interpreted it as an extension of Seongnihak. Their research had little disagreement in seeing the origin of the heterogeneity in Dasan's reading method as the concept of substance and accident of Tianzhushiyi. However, the concept presumed to have been used in Tianzhushiyi does not correspond well with that of Dasan’s “Four-Seven” theory, and even shows contradictory features. This suggests the possibility that the source of the heterogeneity is not the only Tianzhushiyi. This paper specifically analyzed Dasan's reading method, taking note of the previous research results, and suggested the preliminary possibility that his heterogeneous point of view could be a book other than Tianzhushiyi. In addition, it looked at how the foreign knowledge that Dasan used contributed to making Dasan's own thoughts. Thus Chapter 2 showed that Dasan's interpretation deviated from the existing controversy structure by comparing various answers with the questions that Jeongjo raised in the contest. Subsequently, in Chapter 3, it was revealed that Dasan accepted Lee Byeok's view and understood Toegye’s theory as a knowledge system that cannot compete or compare with Yulgok’s theory. Chapter 4 discusses that Dasan's “Four-Seven” theory is a claim composed by juxtaposing the interpretation frame of Seongnihak and Seohak, and raises the possibility that Tianzhushiyi is not the origin of the heterogeneity. In conclusion, it was mentioned that Dasan's reading method eventually cracked Seongnihak’s perspective based on undifferentiated thinking and created another intellectual tradition.
