本文探討了朱熹哲學中「理一分殊」的觀念，並指出「理一分殊」的觀念在朱熹哲學中有道德倫理、形上學、宇宙論等種種不同的面向。經由「理一分殊」，朱熹認為，道德倫理有其客觀之依據，其來源於生生不息之天道。而這一點似乎可以為當代建構世界倫理的工作上提供一些貢獻。

This article is intended to examine Zhu’s Xi’s idea of “Li YI Fen Shu” (the heavenly way is one, and its manifestations are many) and point out the moral, metaphysical and cosmological dimensions of this idea. Zhu Xi thought that moral ethics was objectively justified and originated from the everlasting way of heaven. This aspect somehow seems to contribute to the contemporary construction of world ethics.
