建设性后现代主义对解构主义、虚无主义进行批判,主张“在解构基础上实施建构”。在此意义上,建设性后现代图书馆学的方法论阐释了反对“去本质化”、“去理性化”和“去主客二分化”。图书馆学研究成果的更新离不开方法论的更新,借鉴“建设性后现代”方法可以深化图书馆学理论研究,为更加详尽地阐释图书馆现象提供了新的方法论。 Constructive postmodernism criticizes deconstruction and nihilism and advocates “implementing construction on the basis of deconstruction.” In this sense, the methodology of constructive postmodern library science explains the opposition to “de-essentialization”, “de-rationalization” and “subdivision of subject and object.” The update of library science research results can not be separated from the updating of methodology. Using the method of “constructive postmodernism” can deepen the study of library science theory and provide a new methodology for explaining library phenomenon in more detail.
