The academic circles usually date back to the theory of conscience's self-negation in 1947 on Mou Zongsan's theory of self-negation, 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.
