1472–1529· Philosopher· Asian traditions
Well documentedSolid records, texts or physical evidence.
Ming dynasty official and general who taught that moral knowledge lies in the mind itself and that true knowing is acting.
See it on the Philosophy map →The idea
The idea: knowing and acting are one (zhi xing he yi 知行合一); someone who 'knows' to honor parents but does not, does not yet know. As a young man, Wang Yangming (王陽明) followed Zhu Xi and stared at bamboo for seven days to grasp its principle, and fell ill. Exiled to remote Guizhou in 1506, he concluded that principle is in the mind, which has an innate knowing of the good (liangzhi 良知). The main objection: trusting inner conscience lets anyone call a whim moral.
Why it matters
His school dominated late Ming thought, was condemned as heresy in Joseon Korea, and inspired Japanese activists of the Meiji Restoration through Yomeigaku, its Japanese form.
Legacy and sources
Students collected his sayings and letters as Instructions for Practical Living (Chuanxilu, from 1518); Ming records document his career, including crushing a princely rebellion in 1519.
Still debated
How much he borrowed from Chan Buddhism, as critics charged, is still debated, as is the meaning of his late, compressed 'Four Sentence Teaching'.

▸Zhu Xi and the Four Books was challenged by Wang Yangming: unity of knowing and actingWell documented
The connection
Zhu Xi said moral understanding comes from investigating the principle in things, step by step. Wang Yangming rejected this: principle is in the mind, not outside it, and knowing cannot be separated from acting. He even argued that Zhu Xi's mature views agreed with his own, compiling Zhu Xi's late letters to prove it.
When and how
Ming China, from the bamboo episode around 1492 to 1518, when Wang published Zhu Xi's Final Conclusions Reached Late in Life.
How we know
Wang's Instructions for Practical Living and his compilation engage Zhu Xi explicitly; critics soon showed that some letters he called late were actually early.
Debates and open questions
Whether Wang's school was a new philosophy or a return to Mencius and Lu Jiuyuan, whom he championed, is still debated.
▸Wang Yangming: unity of knowing and acting was condemned by Yi Hwang (Toegye)Well documented
The connection
Toegye saw Wang Yangming's teaching as dangerous: by locating principle wholly in the mind and merging knowledge with action, it seemed to abandon study and slide into Chan Buddhism. In a point-by-point critique of Wang's Instructions for Practical Living he branded it heterodox, and Joseon orthodoxy largely shut Wang's school out for centuries.
When and how
Joseon Korea, 1560s; Toegye wrote his Critique of the Instructions for Practical Living as Wang's books began circulating in Korea.
How we know
Toegye's critique survives in his collected works; Wang's school in Korea later survived only quietly, as in Jeong Je-du's Ganghwa school.
Debates and open questions
Some scholars argue Toegye attacked a caricature of Wang; others say he correctly saw how far Wang had departed from Zhu Xi.
