楊簡의『楊氏易傳』에 대한 고찰

Abstract

This paper aims to illuminate Yang Jian’s philosophy. Especially I will focus on Yang Jian’s commentary of the Yijing which, I think, is the main commentary of three kinds of commentaries Yang Jian wrote. Thinkers at the time can justify one’s thought only through the scriptures. Yang Jian’s master, Lu Jiuyuan, founded the school of Xin-xue (心學, Study of Mind), but he did not write any kind of commentary on the scriptures. So in this sense, Lu Jiuyuan’s main propositions were still declarative rather than demonstrative. Presented aim through the declaration might attracts the attention of people, but it is difficult to persuade people. So this is why we need to investigate Yang Jian’s philosophy. Yang Jian tried to support his master Lu Jiuyuan’s declarative propositions. The school of Xin-xue is finally established through the theoretical work of Yang Jian. Yang Jian’s Commentary of the Yijing adopt moral approach instead of numerological approach in terms of both form and content. Yang Jian removed all “the Appendixes” in his commentary of the Yijing. His comments were limited to hexagrams and lines. In addition, Yang Jian suspect that many passages of “the Great Appendix” is not written by Confucius. “The Great Appendix” was the base of Cheng-Zhu’s moral metaphysics at that time. And one of the important propositions of Yang Jian’s Commentary of the Yijing is “Moral mind which none-Substantiated” which has rich implication for the school of Xin-xue. Through these several points we may think that Yang Jian tried to establish his own unique point of view on the Yijing different from Wangbi and Chengyi, also Zhuxi.
