儒學思想的意涵奠基於人身之上以及人與人相處的人倫關係中。然而，歷來卻甚少談論情侶關係之愛，尤其是同性部分。關於愛情一直是人際中不可或缺的情感，但一般認為愛情的境界不高也較缺乏系統性地研究。本文試圖從劉嶯山誠意哲學思想脈絡連繫至同性愛情倫理的道德形上學，並將意根的普遍價值由自我內在向外擴充到具體的愛情問題上，從慎獨為入手處走向收攝於誠意的工夫，以正心誠意之內聖方法開出外王的道路，將對政治上的論述點出愛情倫理基本規範的關聯性，使學問踐履在行為處事之中，形上形下互相參透，提出儒學因應現代情感課題的詮釋進路。;The implications of Confucian thought are grounded in human embodiment and in ethical relationships between individuals. However, little attention in previous research has been given to romantic relationships, especially same-sex love. While love remains an indispensable dimension of huamn relationships, it has been traditionally regarded as lacking in spiritual profundity and has suffered from insufficient systematic study. This paper attempts to bridge Liu Jishan’s philosophy of Cheng-Yi (誠意) to the moral metaphysics of same-sex love ethics. It also seeks to expand the universal value of Yi-Gen (意根) from internal self-cultivation outward to concrete issues of romantic love. Beginning with the practice of Shen-Du (慎獨), this paper converges into Cheng-Yi (誠意) practice and explores the path from Nei-Shen (內聖) to WaiWang (外王). In addition, this paper highlights the relevance between political discourse and the fundamental norms of romantic ethics, aiming to integrate scholarly practice into behavior and conduct, bridging metaphysical and practical dimensions, and offering a Confucian interpretive approach to modern romantic issues.
