焦循易学方法论的哲学意义

文章认为焦循通过“旁通”、“当位失道”、“时行”、“八卦相错”、“比例”五图,编织了一套表现为象数形式的逻辑类比推理的思想构架。并将自己的道德理想尽数纳入构架之中。这样。焦循一方面确立了研究易学的方法论,另一方面也具有以“旁通”为主体的哲学意义。焦循易学的方法论,标志着清代中期易学的重要转向,它已迈出象数与义理诠释易学的旧轨。然而将易学的探求严格限定在各种法则的框架之内,因而也就混淆了易学的象数系统与义理系统的各自独立性。因此,易学的哲学意义也就被逻辑推理的工具价值所取代。

Philosophical significance of the methodology of JIAO Xun's Yi learning

By the diagrams such as Pang long (laterally linked hexagrams) , Dang wei shi dao (matching positions but losing Dao) , Xiang cuo (interchanging hexagrams) and proportion illustrated in his Yi tu lue, JIAO Xun founded a logical analogous inferring image-number structure and fused his moral ideal into it, having established not only the methodology for the studies of the Yi learning but also a philosophical significance depended mainly on the theory of Pang long. Its positive significance is shown as that it runs out of the old trail of interpreting Yi with philosophical connotations or images & numbers, marking an important diversion of the studies of the Yi learning in the mid and late Qing Dynasty (1644-1911). Yet, its negative influences are shown as that it mixed the independence between the image-number system and that of philosophical connotations of the Yi learning, philosophical values of the Yi learning being replaced by the tool value of logical analogy of it.
