Who they are

Zhu Xi (1130–1200) was a Southern Song thinker who systematically integrated the Neo-Confucian thought begun by the Northern Song "two Chengs" (Cheng Hao and Cheng Yi) and built the vast, rigorous philosophical system of the "Cheng-Zhu school," holding that "li" (principle) is the metaphysical fundamental law existing prior to and transcending all concrete things, concrete things being only the differentiated manifestation of "li" in the phenomenal world ("one principle, many manifestations"), and that a person should, through the "investigation of things and extension of knowledge" — that is, exhaustively inquiring into the universal principle behind concrete things — gradually expand the moral knowledge innate in the mind, and at last attain the cultivated state of "preserving heavenly principle and extinguishing human desire." His Collected Commentaries on the Four Books (the Great Learning, the Doctrine of the Mean, the Analects, and the Mencius) thereafter long served as the official prescribed text of the civil examinations of the Yuan, Ming, and Qing dynasties, profoundly shaping the mode of thought and scholarly path of East Asian Confucian intellectuals for nearly seven hundred years — one of the most far-reaching systematizers of Confucian thought since Confucius and Mencius.

Key stories

The Meeting at Goose Lake

In 1175 Zhu Xi and Lu Jiuyuan held a famous philosophical debate at the Goose Lake Temple in Jiangxi, clashing fiercely over whether the "investigation of things and extension of knowledge" should lean toward exhaustively inquiring outward into the principle of all things (Zhu Xi’s stance) or toward directly recognizing the original mind within (Lu Jiuyuan’s stance); the two held to their views without reaching consensus, and this "Meeting at Goose Lake" was seen by later ages as the landmark event of the divergence within Song-Ming Neo-Confucianism between the two paths of the "study of principle" and the "study of mind," its echoes reaching down to the rise of Wang Yangming’s study of mind centuries later.

The Official Status of the Collected Commentaries on the Four Books

Zhu Xi spent his life’s energy writing systematic commentaries on the Great Learning, the Doctrine of the Mean, the Analects, and the Mencius, and in the Yanyou era of the Yuan dynasty Emperor Renzong formally established them as the official prescribed reading of the civil examinations; for more than six hundred years through the Ming and Qing, almost every scholar hoping to enter officialdom through the examinations had to master Zhu Xi’s commentaries — an influence of thought exceedingly rare in the intellectual history of China and all East Asia.
