How a rationalist revival used ancient metaphysics to reshape East Asian society
Born from a desire to counter the mysticism of Buddhism and Taoism, Neo-Confucianism transformed the social fabric of China, Korea, and Japan. It wasn't just a philosophy, but a rigorous system of ethics and administration that governed civil service and family life for centuries.
Emerging from the Tang dynasty and reaching maturity during the Song dynasty, Neo-Conf/ucianism—or *lixue* (School of Principle)—sought to create a more rationalist, secular ethical system. While it borrowed terminology from Taoism and Buddhism, it rejected their focus on spiritual enlightenment and the unreality of the physical world. Instead, thinkers like Zhu Xi (1130–1200) used metaphysics to guide human conduct, emphasizing that reality is a gradual realization of the 'Great Ultimate' and that the universe can be understood through human reason.
The movement was characterized by intense intellectual competition between schools. The dominant Cheng–Zhu school, led by figures such as Cheng Yi and Cheng Hao, focused on the 'investigation of things' (*gewu*) to find principle (*li*) within the world. In contrast, the later Lu–Wang school, led by Wang Yangming (1472–1529), argued that because *li* exists within the heart-mind, one should seek truth through 'quiet sitting' (*jingzuo*) and intuitive knowledge. This shift toward intuition even provided an ideological foundation for radical samurai actions prior to the Meiji Restoration.
Beyond China, Neo-Confucianism became a powerful state ideology. In Korea, following the 1392 establishment of the Joseon dynasty, it was used to restructure society, leading to the creation of educational institutions like *seowon*. However, the system's eventual rigidity and dogmatism contributed to internal political factions and hindered socioeconomic change. Despite these tensions, the philosophy's influence remained profound across East Asia for over half a millennium, shaping everything from imperial examinations to family rituals.
