It is said that Confucianism ruled almost all fields of traditional C and chinese art theory was not an exception of it. A new form of Confuc(Neo-Confucianism) was built in Sung dynasty and its influence on ar was the same as before. Traditionally, Confucianism had a negative pe about art. It was because art interfered with the cultivation of pers essay will inquire into a possibility of affirmative viewpoint of art such a characteristic of Confucianism especially Neo-Confucianism dynasty. In Sung dynasty the most eminent art theorist was Su Shi(蘇軾), main stream of Confucianism in Sung dynasty was that of from Zhou Dun Yi(敦?) to Zhu Xi(朱熹) and it was Sung-Ming Li-Xue(宋明理學) that led Ch culture in general after Sung dynasty. Therefore, though art theory dynasty was influenced by Su Shi, it was within the boundary offe Neo-Confucianists. The examples of the art theory of Li-Xue were "wen Yi Zai Dao"(文以? Art is the means of transferring Dao) and "wan u Sang Zhi"(玩物喪志: B indulged in exterior things makes one lose his intention). It is certa assertions played a negative role in art and art theory at that time factors of Li-Xue, for example "Tian Ren He Yi"(天人合一), became foundation of the later art theory. It is a matter of course that Li-Xu persist throughout later ages, and the reason was the self-contradictor -the relation of nature(性), sentiment(情) and mind(心). A new trend o art theory in later ages could emerge by breakthrough of the contradicto In conclusion, Li-Xue in Sung Dynasty had influence on art and art thlater ages in different ways. On the one hand it had a negative influence on art and art theory in that ignored the value of art itself. On the other hand, it presented the value that art should pursue such as Dao, Tian Ren He Yi, etc. Furthermore, decisively it offered the bases of possibility and limit of chinese art and art theory at that time and of later ages. Therefore, it is necessary to grasp the art theory of Li Xue to understand the chinese art and art theory. It is in this that the aesthetic significance of Li Xue in Sung Dynasty lies.
