The "Four Books" is a collection of classical Chinese texts that form the foundation of Confucianism. Compiled during the Song Dynasty, these texts include the Analects, the Great Learning, the Doctrine of the Mean, and the Mencius. They emphasize moral philosophy, ethics, and the importance of education in personal and societal development. These works are essential for understanding Confucian thought and its influence on Chinese culture and governance. The "Four Books" serve as a guide for personal conduct and social harmony, promoting virtues such as benevolence, righteousness, and propriety in relationships and society at large.
