The significance of Zhang Xue-cheng's historical philosophy lies not only in some practical historical methodologies but also in its general and philosophical thinking about Chinese history and culture. As the offspring of the development of Lu and Wang's doctrine of mind in the Qing Dynasty, Zhang's historical philosophy dissolved the static and mechanical logic analyses of the intellectualist tradition and considered history, academy and culture as an ever-changing and cyclic process, of which everything is specific, limited, and reasonable. They are the manifestations of dao rather than the absolute truths, as what is meant by ”all the six classics are history”.
