정약용의 소옹 비판 ― 「팔괘차서도」와 「팔괘방위도」를 중심으로

Abstract

The purpose of this paper is to elucidate the philosophical meanings of Jeong Yag-yong's “Treatise on Shaozi's Earlier Heaven” which is a part of Yixuexuyan(Collection of Critical Essays on some Major Theories about the Classic of Change). Present paper deals with the preceding three chapters that consist of eight chapters of the Treatise. The first chapter is concerned with Shao Yung's Diagram of the Sequence of the Eight Trigrams and the second is related to the Diagram of the Arrangement of the Eight Trigrams. In addition, the third chapter is involved in elaborating again on the meanings of the previous two diagrams. The main topic of Jeong Yag-yong's Treatise is to make a critical assessment of Shao Yung's theory of the Earlier Heaven. First of all, it is to be noted that Jeong Yag-yong's point of view is diametrically opposed to Shao Yung's perspective. Jeong Yag-yong's critical view toward Shao Yung was formulated by the influence of the Kaozheng(考證) Movement during the late Ming and early Ching dynasty that put emphasis on the evidential research. Especially, Mao Jiling(毛奇齡) is presumed to have exercised a direct influence on Jeong Yag-yong's view. Jeong Yag-yong's criticism on Shao Yung is conducted in two aspects. The first aspect is the difficulty of finding the evidence of corresponding literature that supports Shao Yung's assertion of the Earlier Heaven. The second is the unreasonable way in which Shao Yung set forth his argument.
