牟宗三先生所建構的道德形上學備受學人關注，相關研究成果不斷湧現。這些研究成果無疑為道德形上學的探究提供了不同的視角，有助於我們深入把握牟先生的思想；但亦當指出，學人的工作仍有未盡妥善處，其中一點就是他們往往循其常義或表義來解讀牟先生的哲學語言，而不察其另有玄義，從而造成了理解上及批評上的偏差。基於此，本文試圖分析、釐清牟先生的哲學語言所含的特殊用法，並據此為道德形上學確立一新的詮釋。本文指出：這一新詮既可為牟先生的哲學語言之解讀提供一合理途徑，亦可消解道德形上學所遭到的某些常見的挑戰。

It has been a trend to study moral metaphysics, a kind of metaphysical theory established by Mou Zongsan, who is one of the representatives in the field of modern Chinese philosophy, and publications on this issue has been increasing. Definitely, these publications can be considered as providing approaches for studying moral metaphysics as well as for grasping Mou's thought; but, it should also be recongized that, scholars have probably been led to a misunderstanding or even an an irrelevant attack of moral metaphysics, for they have always limited themselves to the general or literal meaning, rather than the real meaning, of Mou's language. In this regard, this article aims to provide a new interpretation of moral metaphysics by clarifying how Mou's philosophical language are constituted a peculiar use, which can be seen as a reasonable response to challenges offered by critics who do not on the right track.
