程颐易学视野下的理本论构建——基于对“体用一源”说的考察

The Construction of Li-Based Theroy in the Vision of Cheng Yi’s Yi-Ology—Based on the Investigation of the Theory of “Substance and Function Sharing the Same Origin”

摘要: 程颐的理本论思想是理学研究的核心论题，而此论题正是在程颐易学思想的框架中建构的。本文首先从程颐的易学的视域下对理与象的关系进行讨论，从而得出“体用一源，显微无间”的诠释原则；其次，重新厘清程颐思想体系中的理气关系，对认定程颐为理气二分的结论加以修正；最后，程颐易学中“顺理”方法的提出为人道向天道的贯通提供了一条路径，成功构建了圆融无碍、体用一贯、天人一体的理本论。

Abstract: Cheng Yi’s Li-based theroy is the core proposition of neo-Confucianism, which is constructed in the framework of Cheng Yi’s theory of Yi-ology. This paper first discusses the relationship between reason and image from the vision of Cheng Yi’s Yi-ology, and then obtains the interpretive principle of “substance and function sharing the same origin, and the apparent and the subtle being inseparable”. Secondly, it redefines the relationship between Li and Qi in Cheng Yi’s thought system and revises the conclusion that Cheng Yi separated Li and Qi. Finally, the proposed method of “following the Li” in Cheng Yi’s Yi-ology provided a path for humanity to connect with the way of heaven, and successfully constructed the Li-based theroy of harmony without obstruction, substance and function sharing the same origi and unity of heaven and man.
