Postmodernism in contemporary literature challenges traditional notions of reality, truth, and meaning. It embraces skepticism, fragmentation, and irony, blurring boundaries between high and low culture while questioning the role of the author and the nature of originality. Key thinkers like Lyotard, Baudrillard, and Derrida shaped postmodern thought, influencing literature, art, and culture. Postmodern writing techniques break conventional rules, using fragmentation, metafiction, and intertextuality to reflect the complexities of contemporary life and challenge readers' expectations.
