The Four Books became the core collection of Confucian education in imperial China.
The Four Books are the Great Learning, the Doctrine of the Mean, the Analects, and the works of Mencius. Although these texts had different origins, the Song dynasty thinker Zhu Xi arranged them into a pedagogical sequence and supplied influential commentaries.
The collection became especially important for the civil-service examination system. From the Ming dynasty onward, examination candidates were expected to master Zhu Xi’s interpretations of the Four Books, making them central to elite education and government recruitment.
The Four Books are distinct from the Five Classics, an older group of canonical works. The two collections were often studied together, but they served different roles in the Confucian curriculum. Zhu Xi’s selection helped make the Four Books the main entry point into later Neo-Confucian learning.
