As for the basic trend of theoretical development in the 21st century,Terry Eagleton and Vincent Leitch give two very different rehearsal judgments.Rooted in the grand narrative stance of Marxism,and thoroughly"re-thinking""orthodox cultural theory",Eagleton set up an"anti-postmodern"road of"after theory";On the basis of the current extension of the"postmodern"landscape,Leitch conceived a"postmodern"model of"theory renaissance"which was grounded in the retrospective"re-exploration"of the"postmodern paradigm of theory".By comparing the heterogeneity of the two judgments,exploring the internal mechanism of their heterogeneity,and pointing out the theoretical approach of"new aestheticism"used as a"reconcile-ation"scheme,we can re-examine the basic trend of theoretical development in the 21st century.
