Qizhi zhi xing 氣質之性 and the Unity of Human Nature: Zhu Xi’s Theorization of the Goodness of Human Nature * LEE Junghwan Abstract The thesis that “human nature is good” was a key doctrinal foundation of the Daoxue tradition since its beginning. Nonetheless, the process of verifying this thesis revealed intricate problems concerning the moral definition of human nature and its categorization. In particular, because of its implications of universality and pure goodness, this thesis seems to contradict the empirical facts of the occurrence of immorality and the individual disparities in moral characters. In order to address such problems, Zhu Xi 朱熹 (1120-1200) adopted the ideas of qizhi zhi xing 氣質之性 and the unity of human nature from Zhang Zai 張載 (1020-1077) and the Cheng brothers through re-conceptualizations. First, Zhu Xi re-interpreted qizhi zhi xing in the sense of the mutual non-separability (bu xiang li 不相離) of the universality of human nature and the personal qualities of qizhi. Thus, he provided an explanation for observed disparities in moral character in the light of the influence of the personal quality of the endowed qizhi on the manifestation process of human nature. At the same time, from the perspective of the mutual non- fusionablity (bu xiang za 不相雜), he confined the range of qizhi’s influence to the manifestation process alone, rather than to human nature itself, thus making human nature itself conceptually free from the influence of qizhi and theoretically capable of retaining its quality of pure goodness. Second, to re-establish the thesis that human nature is good on a more solid ground, Zhu needed to redefine the relationship between human nature and sensory desires. Because the latter
