本文在分析西方现代美学“美不可说”的局限性基础上 ,提出“美学必须说” ,“美学只能进行批判性言说” ,“美学批判只具有发现对象局限的功能”等观点。并提出“不美”和“丑”这两个传统美学所忽略区分的范畴 ,对其内涵做了否定主义美学意义上的阐释。 Based on the analysis of the limitation of “beauty not to say” in Western modern aesthetics, this paper puts forward such views that “aesthetics must be said”, “aesthetics can only make critical statements”, and “aesthetic criticism only has the function of discovering the limitations of objects”. And put forward the categories of distinction ignored by the two traditional aesthetics of “not good” and “ugliness”, and make a negative aesthetic interpretation of its connotation.
