论《易传》的象数、义理合一模式与天人合一的理论架构

Unity of Image-numerology and Moral Principle,Integrity of Heaven and Humanity:Unique Quality of the Yi zhuan

《易传》是现存系统解释《周易》古经的最早典籍,对后世历代学人诠解《周易》产生了深远的影响。由于《周易》古经由卦爻符号和卦爻辞组成,卦爻符号与卦爻辞之间的关系便成为后世《周易》研究的关键问题。在《易传》作者看来,《周易》的卦爻辞是由圣人"观象"而来,圣人通过"观象系辞"来揭示易道。换句话说,《周易》所阐发的义理乃以象数为基础。象数蕴含着义理,义理脱胎于象数,二者如水乳之交融而不可分。而《易传》象数与义理合一的模式是以"三才之道"为其理论架构的。开天道以立人道,法天文以立人文,成为《易传》立论的理论支撑。

Yi zhuan, which had exerted far-reaching influence upon hermeneutics of the Zhouyi in the past dynasties, is the earliest literature extant which systematically interpreted the Ancient Text of the Zhouyi. Now that the Ancient Text of the Zhouyi is composed of the symbolic system and the statements affiliated to the hexagrams and lines, the relationship between the two components turned out to be a critical issue in the studies of the Zhouyl. For the authors of the Yi zhuan, the hexagram and line statements resulted from the sages＇ contemplation on the images conceived in the semiotic system whereas the moral principles exposed by the Zhouyi are based on the image-numerology. In other words, image-numerology conceives moral principles and they can not be separated into two. Furthermore, the unity of image-numerology and moral principles is unfolded against the integration of heaven and humanity. Deducing the Dao （Way） of human from the Dao of heaven is the theoretic bedrock against which the Yi zhuan expounded the unity of numerology and moral principles.
