정약용 『周易』 해석의 경학사적 이해

Abstract

This article examines the characteristics of Jeong Yakyong’s interpretation of the I Ching (the Book of Changes) and its significance in the history of the Confucian classics. The Han Dynasty’s image numerology influenced the methodology of Jeong Yakyong’s interpretation of the I Ching, and it can be said that it was greatly influenced by the theory of Wu Cheng in the Yuan Dynasty, which inherited the interpretation of Zhu Xi. Contrary to previous studies that found no significant relationship between Jeong Yakyong’s interpretation and that of Zhu Xi, we should consider the possibility that Wu Cheng’s interpretation of the I Ching provided a clear clue to the Four Methods of Zhu Xi’s Interpretation. The most striking feature of Jeong Yakyong’s interpretation is that he proposed an interpretation that combines Tuiy and Yaobian. Jeong Yakyong not only borrowed the theories of Tuiy and Yaobian from the history of I Ching studies, but he succeeded in interpreting the texts by integrating the two into one with a new perception, a breakthrough in the history of I Ching studies. Jeong Yakyong was also active in the use of huti, and was particularly fond of lianghuzuogua, a method of creating an additional hexagram by superimposing two nuclear trigrams. Some have criticized this as arbitrary overuse. However, it can be seen as an act of service to Heaven, an effort to reveal the will of Heaven by creating images. Jeong Yakyong was also influenced by Seongho’s study of the I Ching, and while there is some overlap with that of Shin Hu-dam, it can be seen as a very unusual fact in the history of thought that Jeong Yakyong was unaware of its existence. In a broader sense, it can be seen as a serendipitous result of the Seongho School’s dedicated study of Confucian scriptures and its shared emphasis on self-knowledge.
