Mou Zongsan (1909-1995) is one of the representatives of Modern Confucianism and an important Chinese philosopher of the twentieth century. This two-volume set critically examines the philosophical system of moral metaphysics proposed by Mou, which combines Confucianism and Kantianism philosophy. The author looks into the problems in the moral metaphysics by Mou and his systematic subversion of Confucianism on three levels: ethics, metaphysics and historical philosophy. The first volume discusses Mou's distortion of traditional Confucian ethos on the ethical level by introducing Kantian moral concept and misappropriating Kant's concept of autonomy. In the second volume the author critiques Mou's philosophical development of Confucianism in terms of conscience as ontology and historical philosophy respectively, which draws on ideas of Kant and Hegel while deviating from the classical context and tradition of Confucian thoughts.The set will appeal to scholars, students and philosophers interested in Chinese philosophy, Confucian ethics, Neo-Confucianism and Comparative Philosophy.
