Zhu Xi

Zhu Xi, formerly romanized Chu Hsi, was a Chinese philosopher, historian, politician, poet and calligrapher of the Southern Song dynasty, born in 1130 and died in 1200. As a leading figure in the development of Neo-Confucianism he played a pivotal role in shaping the intellectual foundations of later imperial China, seeking to integrate moral self-cultivation, classical interpretation, ritual practice and cosmological theory into a coherent framework, while criticizing approaches, particularly within contemporary Buddhist traditions, that claimed immediate insight detached from ritual, learning and moral practice. His extensive commentaries on the Four Books became the core texts of the imperial civil service examinations from 1313 until their abolition in 1905, and he advanced a philosophical methodology known as the investigation of things alongside meditation as essential to moral and intellectual self-cultivation. His thought became the official state ideology of China from the Yuan dynasty onward and was later institutionalized in Japan, Korea and Vietnam through their own educational and civil service examination systems, shaping political ideologies, social hierarchies and cultural values for centuries. Zhu built upon the teachings of the Cheng brothers, further developing their metaphysical theories of li, meaning form, and qi, meaning matter, and his students recorded thousands of his conversations in writing.
