Cheng Hao
"Substance of Mind and Substance of Human Nature" 心體與性體 (1968–1969). This is probably the most studied of Mou's books, and by far the most famous in the West. It is a three volume history of Confucianism in the Song (960-1279) and Ming (1368-1644) dynasties, often called "Neo-Confucianism" in the West. It challenges usual two-part division of Neo-Confucian thought into a "school of principle" ("lixue" 理學), the Cheng-Zhu school represented by Cheng Yi, Cheng Hao, and Zhu Xi, and a "school of mind" ("xinxue" 心學) or Lu-Wang school represented by Lu Xiangshan and Wang Yangming. Mou identifies a third lineage, whose main figures are Hu Hong (Hu Wufeng) and Liu Zongzhou (Liu Jishan), which best conveys the basic message of the classical sage Mencius. Mou's later book "From Lu Xiangshan to Liu Jishan" () (1979) is treated as the fourth volume of this book.
