焦循是清代乾嘉时期的著名学者,他花费几十年的时间,写出《易学三书》。焦循的《易》学研究颇有自己的特色,为清代阮元、王引之等学者推崇,被誉为“石破天惊”之作,引起了当时学术界的震动。此后,皮锡瑞、章太炎也认为其书“独僻畦町”而“足以名其家”。焦循的《易》学究竟独特在哪里?前人往往语焉不详。本文旨在就焦循的《易》学体系和特色,作一些初浅的探讨。 Jiao Xun is a famous scholar during the Qianlong and Qing dynasties. He spent several decades writing “Three Books of Yi-ology.” Jiao Xun’s Yi studies have their own characteristics. They were praised by scholars such as Ruan Yuan and Wang Yinzhi in Qing dynasty. They were praised as “shocking” and caused the academic shock at that time. Since then, Pi Xirui, Zhang Taiyan also think of his book “alone secluded town” and “enough to be famous.” Jiao Xun’s “Yi” learn exactly what is unique? The purpose of this paper is to make some preliminary discussions about Jiao Xun’s Yi-ology system and features.
