Carnivalization,one of Mikhail Bakhtin's key concepts,means polyphony,the centrifugal force of language,the gay interdepen dence of things,perspectivism and performance,participation in the wild disorder of life,the immanence of laughter.Carnivalization in Closing Time covers a wide range from the convolving and confusing conference of ACACAMMA to Milo Minderbinder's stealth bomber,from disordered metropolitan living,to a socialite wedding in the bus terminal.Closing Time illustrates carnivalization as an antisystem,a second life standing for postmodernism itself.This article interprets Closing Time on three levels: the carnivalization of world experience,the carnivalization of art thought,and the carnivalization of literary genres.
