It is said that aestheticians, art critics and philosophers today are yearning for some kind of 'salvation' for contemporary art. They would like to re-establish foundations or authentic roots for art, which is basically the aesthetic experience, so as to enable resistance to the trend of contemporary discourse, i.e. pure discursive reflection and intertextuality. This reference to ontologically based norms, which is claimed to be the central notion of contempporary aesthetics today, may be for different reasons, is shared among yound aestheticians in Communist China. In 1988, a modern aesthetics system was published in a book form in China, entitled by the same name, Modern Aesthetics System. (《現代美學體系》 ) It is edited by Prof. Ye Lang, the head of Philosophy department of Peking University, and it written collectively by a group of 9 young aestheticians. The book aims to become a basic textbook for colleges and readers nationwide introducing aesthetic theories using new theoretical models. "Aesthetic Ganxing", a new term introduced in the book, is suggested to replace the old word 'aesthetic experience' in aesthetics and has become the central core of study in this modern aesthetics system in China. This article is both an introduction and a critical analysis of the notion to examine how new the notion is and towards what direction has it been developed into. The article is composed of the following six sections: I) Introduction: introducing the significance of the notion of "aesthetic ganxing" II) A content analysis of the notion of "aesthetic ganxing" III) An examination of the epistemology of the "Modern Aesthetics System" IV) A historical reflection on the debates of the origin of beauty in Marxist China V) A critique of the subject-object relation in the notion of "aesthetic gaxing" VI) Conclusion After a detailed content analysis of the notion, the epistemology behind the notion is examined. The notion is also compared with the discussion of aesthetic experience in the modern history of aesthetics in China after which it is evaluated and its theoretical problems are investigated and presented for consideration.
