朱熹《四書章句集注》為宋元以來最重要之經典，人所共知，然而原本與《四書或問》彼此證發的方式，卻少人注意。尤其朱熹學力日進，日後關注集中於《四書章句集注》，《四書或問》更為人所忽略。其實相同之處，可以見其用意；相異地方，可以見其轉折，《四書或問》留下解讀《四書章句集注》非常珍貴的線索。只是《四書章句集注》與《四書或問》體例殊不一致，文字相似而異，校勘並不容易，為求精確，筆者選擇以《學庸章句》與《或問》為範圍，檢覈其中之異同，從體例之間，以及彼此相應之文字，一窺朱熹完成《四書章句集注》，形就四書體系後續之經學思索進程。

Zhu Xi's Sishu zhangju jizhu, as everyone knows, has been one of the most important canons since Song and Yuan dynasties. However, it was ignored that the discourses in Sishu zhangju jizhu and Sishu huowen could be used in elucidating and proving each other. Moreover, inasmuch as scholars focus on researching in Sishu zhangju jizhu recently, there are few people attaching importance to Sishu huowen. In fact, there are a lot of exquisite clues in Sishu huowen, which are valuable to illustrate the context in Sishu zhangju jizhu. We could obtain Zhu Xi's intention according to the identical conditions, while get the conversion from the distinct conditions, between these two canons. Nevertheless, it is hard to collate the context for the styles are not in chorus and the wordings are unlike in the two canons. To clarify the upshot exactly, I will concentrate on Xue Yong jizhu and Sishu huowen, contrasting the styles and wordings in them, so detect Zhu Xi's course of founding the system of the learning of Classics.
