李道平疏文中的易学思想

The Yi-ology Theory in Li Daoping's Exegeses

自清代乾嘉以来,沉寂已久的汉代象数学得以再次勃兴。在此易学学术语境下,李道平明确提出"言象数而义理在其中"的易学观,推尊汉代象数的治《易》之法。为追本溯源,李道平作《易筮遗占》一卷,对《左传》《国语》中的十六则筮例进行了较为全面的研究,亦对"之八"、"皆八"等三则疑难筮例明抒其见。因汉儒《易》注有赖李鼎祚《周易集解》而留存,李氏又作《纂疏》以疏通、彰明之。其疏文除诠解汉易旧说、考辨字义文意外,又参以己意。其中二百余条"愚案"疏文,充分反映了李道平本人的易学识见。约言之,其"愚案"内容不外发挥汉易、引证字义、阐发义理和兼采宋学四端。总体而言,李氏《纂疏》虽偶有失当处,但毕竟瑕不掩瑜。迄今为止,此书仍为学者入门汉易乃至研习易学之锁钥。

Since the Qianlong and JiaQing period of Qing dynasty,the image and number Yi-ology had risen again,although it was out of sight for a long time. On this horizon of the Yi-ology,Li Daoping suggested the theory＂describing the image and number including the principles＂in order to manifest the Yi-ology in Han dynasty. Aiming to trace the source,Li Dao-ping wrote＂Yi and divination＂,completely researching the 16 divination cases in＂Zuo zhuan＂and＂Guo yu＂,and gave his understandings about the difficult divination cases about＂eight＂. The work＂Zhouyi jijie＂by Li Ding-zuo described the theory of Han Yi,so Li Dao-ping wrote＂Zuan shu＂to clarify and elaborate it. Not only did he interpret the Yi-ology in Han Dynasty and reflect the literal meaning,but also his exegeses were accorded to his own conceptions. There were 200 pieces of＂methinks＂exegeses illustrating Li Dao-ping＇s own idea. Generally speaking,the contents of the＂methinks＂developed the Yi-ology of the Han Dynasty,clarified the literal meaning,explicated the principles and promoted the Neo-Confucian theory in Song Dynasty. Although there were some mistakes,the defects couldn＇t obscure the virtues. Thus far this work was regarded as the starting point of the researching about the Yi-ology in the Han Dynasty.
