Mou Tsung-san
Chinese philosopher who synthesized Confucianism, Buddhism, and Kant.
Mou Tsung-san (Mou Zongsan) was a Chinese philosopher and translator, born in Shandong province and a graduate of Peking University. He is known for his extensive work on Chinese philosophical traditions, particularly Confucianism, Buddhism, and Daoism, and for his engagement with the philosophy of Immanuel Kant, whose three Critiques he translated from English, possibly first, into Chinese. Over the last 40 years of his life, he wrote histories of Neo-Daoist, Confucian, and Buddhist philosophy (totaling six volumes) and constructive philosophical treatises, culminating in his 1985 work *On the Summum Bonum* (Chinese: 圓善論; pinyin: yuanshan lun), which attempted to rectify problems in Kant's system through a Confucian-based philosophy reworked with concepts appropriated from Tiantai Buddhism. In the People's Republic of China, he is especially famous for his cultural traditionalism and his defense of democracy as a traditional Chinese value.

Lore & Background
Mou Zongsan was born into the family of an innkeeper in Qixia, Shandong. He went to Peking University for college prep in 1927 and undergraduate courses in 1929, during which he became a follower of Xiong Shili, author of the *New Treatise on Consciousness-only*. After graduating in 1933, Mou moved around the country working as a secondary school teacher and a faculty member at different universities. In 1949 he followed the Nationalist government to Taiwan. His student at Tunghai University was Tu Weiming. In 1960 he moved to Hong Kong and eventually took up a post at New Asia College in Hong Kong (now part of the Chinese University of Hong Kong) and helped found New Asia Middle School. During the last two decades of his life Mou was something of an intellectual celebrity, lecturing frequently on Confucian, Buddhist, Daoist, and Kantian philosophy at Hong Kong University, National Taiwan Normal University, and National Taiwan University. He died in Taipei in 1995, leaving dozens of disciples in top academic jobs in Taiwan and Hong Kong.
Reader's Guide
Mou Zongsan's significance lies in his comprehensive re-interpretation of Chinese philosophical traditions through the lens of Kantian philosophy and Tiantai Buddhism. His histories of philosophy include *Physical Nature and Speculative Reason* (1963) on Neo-Daoism of the Wei-Jin dynasties; *Substance of Mind and Substance of Human Nature* (1968–1969), a three-volume history of Song-Ming Confucianism that challenged the usual two-part division by identifying a third lineage whose main figures are Hu Hong and Liu Zongzhou; and *Buddha-Nature and Prajna* (1977), which upends the usual recognition of the Huayan school and puts the Tiantai school in first place. His constructive treatises include *Intellectual Intuition and Chinese Philosophy* (1971), applying the Kantian idea of 'intellectual intuition' to Chinese philosophy; *Phenomenon and Thing-in-Itself* (1975), developing his doctrine of 'two-level ontology'; and *On the Summum Bonum* (1985), his last major work, which attempts to use Tiantai ontological concepts to find a Confucian solution to Kant's problem of the highest good. Mou's philosophy develops as a critique and transformation of Kant's critical philosophy, asserting a moral metaphysics that ascribes human beings the capability of intellectual intuition, which Kant believed only possible for God. Mou's legacy includes dozens of disciples in top academic jobs in Taiwan and Hong Kong, and his defense of democracy as a traditional Chinese value made him especially famous in the People's Republic of China.
