心之性情與感通：唐君毅對孟子心性論的詮釋

合理詮釋孟子的「四端之心」及其相關概念，是準確把握孟子哲學的重要前提。當代新儒家唐君毅在繼承宋明儒學相關討論的基礎上，將孟子的「四端之心」界定為「性情心」，並對性、情、心之間的內在關聯，「端」的含義，如何「擴充」「四端之心」以成德，心之情感面與理性面之間的關係，等問題均給出了頗為細膩且富啟發性的詮釋。唐氏力圖在自然主義、心理學的詮釋進路之外，對孟子的心性論予以同情的了解，其說因此也為反省當前英語世界道德心理學進路的孟子詮釋提供了一個很好的參照。

How to interpret the concept of Mind-Heart in Mencius' philosophy is a controversial issue. In the English-speaking world, it is very popular to give an analysis of this concept from a moral psychological approach. But many contemporary Chinese philosophers, such as Xiong Shili, Mou Zongsan and Tang Junyi, object the naturalistic interpretation of Mencius' philosophy definitely, and try to reconstruct Mencius' philosophy of Mind-Heart through a transcendental method. There are many insightful discussions about Mencius' philosophy in Tang's books, which deal with some important problems that are crucial to understand Mencius' thought of Mind-Heart, such as the essence of Mind-Heart, the meaning of duan (端), how to extend (擴充) the Mind-Heart, and the relationship between feeling and reason, etc. In this article, I will explain Tang's discussions systematically, and point out the significance of Tang's interpretation of Mencius' philosophy.
