從學理上看，中華文化長遠的發展，訴求的是天下之救贖與個體幸福之實現，那麼，這種價值取向是如何推定的？其根據為何？以及，人有以實踐、體現此價值指標的動力依據又為何？總之，這些都是伴隨類似理想開展而來的待解問題，而「天人合一」詮釋正是試圖闡釋這種理想所擁有的根據（法則是依——若是「天」，或即「外在化法則」；若是「人之自性」，或即「內在化法則」），並同時企圖保有及闡明人之自本自根、自主的實踐體現動力（自律），從而發展出來的詮釋模型。但是，這種詮釋模型固有其困難，本文嘗試說明其義、提出不同的解決方案，從而主張有可能在為了免除詮釋所衍生的困難時，解消這種詮釋模式。

Theoretically, the far-reaching development of Chinese culture may be taken as a resort to the salvation of the world and the realization of the individual's well-being. If so, then how is this value-approach being presumed? and on what grounds? In the meantime, what are the bases on which human is motivated to practice and embody this value index? These are the problems yet to be solved that have come along with the ideal development of Chinese culture. In this paper, I expound the interpretation adopting the conception of tian-ren-he-yi as the grounds on which the problems have been solved. (The grounds are law-dependent. If the ground is tian, then it is likely an external law. If the ground is human nature, then it is likely an internal law.) The conceptions of tian-ren-he-yi have also been interpreted as a preservation and an illustration of human's root as well as the motive (driven by oneself) to realize the practice and embodiment of this ideal value. Thus, such kind interpretative model is thereby developed. But such a model of interpretation will surely face difficulties, this paper attempts to propose an alternative solution by which the interpretative mode of tian-ren-he-yi could be explained away.
