Neo-Confucian Philosophy

Cheng Hao and his brother, collectively known as The Two Chengs, were students of Zhou Dunyi. Their work emphasized a dualistic perspective that distinguished between tangible reality and intangible principles. Hao argued that an underlying universal principle, or li, connected all aspects of human nature, celestial movement, and social relations. He asserted that human intellect should be directed toward achieving sage-hood, maintaining that scholarship was the essential instrument for this transformation.

Educational Influence and Legacy

In addition to his political career, Hao established schools at Fugou and Songyang in modern Dengfeng. His influence placed him among the Six Masters of Northern Song, a group credited with defining the philosophical landscape of the era. Following his death in 1085 at the age of fifty-three, the state awarded him multiple posthumous honors, including the title Lord of Purity in 1220 and the title Bo of Henan in 1241.
