關於牟宗三的坎陷論之產生，學界一般追溯至其1947年 的良知坎陷說，然而據本文考察，在這之前，牟宗三還有認識心之坎 陷、直覺的解悟之坎陷的說法。本文以概念脈絡法，1對牟宗三早期 的這三種坎陷說進行了證成，並考察了坎陷概念的形成與它們之間 的發展線索。

The academic circles usually date back to the theory of conscience’s self-negation in 1947 on Mou Zongsan’s theory of selfnegation, while this paper will show that Mou has other theories about self-negation of cognitive mind and intellectual intuition before his theory of conscience’s self-negation. Based on the method of concept’s contextualization, the paper will justify the three kinds of theory about self-negation, and investigate the birth of self-negation concept and the developing clue among the three kinds of theory.
