《禮記》曰：「獨學而無友，則孤陋而寡聞。」學術無法以一人之力完成，朋友可以切磋、相勉、互助，能補一人之不足。《周易．繫辭傳》曰：「方以類聚，物以群分。」志趣相投的人們會自然湊合，形成學術社群。況且，《周易》博大精深，須與眾人共商、共討，方可略窺其道。又因「易道廣大，無所不包」，可兼容各種領域的人們，故易學類別的學術社群數量尤多。那麼，易學研究者參加學術社群究竟有何意義？可以得到哪些資源和協助？此即是本研究所要去探究的。本論文取清代易學家姚配中及其學術社群為例，深入觀察後，發現姚氏的學術社群成員為之找到研究方向、給予精神支持、提供學術見解、協助稿件校閱等等，促進姚氏易學的長成，也間接有功於清代整體易學的進步。

"Learning alone and without friends makes one solitary and uncultivated, with but littleinformation."-Liji. The academy could not be accomplished with mere one man’s efforts. Friendscould discuss, and encourage and help mutually, making up the insufficiency by mere one man. It wasstated in Zhouyi xi ci zhuan that methods would be together if of the same kind and creations wouldbe classified into groups if of different kinds. People with the same interest match naturally and formthe academic communities. Moreover, Zhouyi is broad and profound; better understanding of whosetheories require collective discussions. In addition, the Dao (Way) of Zhouyi is all-inclusive andattracts people from various fields, contributing to the especially large number of the Zhouyiacademic communities. What does the Yi-ology researchers’ participation in the academiccommunities denote? What resources and assistance could they obtain from the participation? Thatwas what this current article would explore. The author of this current article took Yao Pei-Chung, aYi-ologist in the Qing Dynasty, as an example and, after deep observation, discovered that hisacademic communities found out the research direction for him, supported him spiritually, providedacademic opinions to him, and assisted the proof-reading of his works, which stimulated the growth ofYao Yi-ology and promoted indirectly the progress of the whole academy in Zhouyi learning.
