The document discusses key differences between modern and postmodern perspectives. In modern thought, there was faith in grand narratives and master theories to explain history and culture. Totalizing explanations were accepted. Postmodernism rejects master narratives and grand theories in favor of local narratives and contingent explanations. It also rejects notions of social and cultural unity, seeing them as pluralistic and unclear. While modernism valued authentic originals, postmodernism sees mediated representations and simulacra as more powerful than unmediated reality. For art, modernism saw unique, finished works validated by standards, whereas postmodernism sees art as process, performance and intertextuality validated by audiences.
