This document discusses postmodernism from three approaches: historical, theoretical, and stylistic. Historically, postmodernism reacted against modernism and its ideas of progress, objectivity, and certainty. Theoretically, key theorists like Lyotard, Baudrillard, and Jameson analyzed postmodernism's rejection of grand narratives, hyperreality, and lack of depth. Stylistically, postmodern texts are characterized by concepts like generic blurring, intertextuality, playfulness, and uncertainty. To determine if a text is postmodern, the document proposes combining all three approaches, focusing on stylistic elements informed by historical and theoretical perspectives.
