Abstract
Mou Zongsan 牟宗三 is well known for his Kantian interpretation of Confucianism, while his understanding of Kant’s ethics is itself colored very much by Confucianism. Mou not only coined the idea “heteronomous morality” ; he also maintained that Kant’s ethics actually espouses heteronomous morality. In this essay, I will first analyze Mou’s idea of heteronomy and his criticism of heteronomous morality and point out that, characterizing Zhu Xi’s 朱熹 philosophy as ethics of heteronomy, Mou gives up a fundamental element in Kant’s idea of heteronomy, according to which heteronomous principles are all principles of self-love. I will then expound Mou’s ideas of moral feelings and moral acts presupposed in his idea of heteronomy and criticism of heteronomous morality and contrast my interpretation with two important interpretations, those of Lee Ming-huei 李明輝 and Sébastien Billioud.
