论易学史研究在易佛关系问题上的两个疏忽──兼谈太虚大师的易学思想

On Neglignece Concerning the Relationship between I-ching and Buddhism in Researches of the History of Yi Xue ──Concurrently on Master Tai Xu's Thought on I-ching

易学是中国学术史上的一大显学。学界对于易学史的研究已取得了相当的成就，但这一成就背后却还留存着一个遗憾，那就是我们的易学史研究疏忽了易佛关系这一大课题，这包括两个方面：（一）我们没有研究在佛教传入中国的前期，为什么佛教在与儒学和道学相沟通的同时却不与易学相沟通；（二）我们没有重视宋明以后存在的大规模的易佛沟通现象。本文以素描的方式勾画出了一幅被学者们忽略了的易佛关系图，有理有据地对疏忽易佛关系的研究状态提出了警策，并以太虚大师的易学思想为例，说明了易佛关系是不应该被疏忽的。

Yi Xue (I-ching learning) is a protrusive school in the history of traditional Chinese learning. Academic circles have obtained considerable achievements in the study of the history of Yi Xue, but there still exist regeret behind these achievements. That is: in the study of the history of Yi Xue, we neglected to study the correlation between I-ching and Buddhism. The paper points out that we neglected two spheres. At first, we did not study why, in early period when Buddhism spread to China, Buddhism was interlinked with Confucianism and Taoism but not interlinked with Yi Xue at the same time. Secondly, we paid less attention to the large scale of interlinking between I-ching and Buddhism after ho and Ming dynasties. For this reason, this paper sketched the relationship between I and Buddhism neglected by scholars, warned people of the fact of the negligence, and set master Tai Xue's thought on I as example to expound that the relationship between I and Buddhism ought not to be neglected.
