This article studies the profound transformations ushered in by postmodernism in the mid-20th century, focusing on its impact on culture, truth, representation, and the traditional understanding of knowledge. Contrary to the view of postmodernism as a linear progression from modernism, we explore the perspectives of Jean-Francois Lyotard and Jean Baudrillard, presenting it as a cyclical moment within the continuous innovation of high modernism. Lyotard redefines the role of postmodern artists and writers as akin to philosophers, liberated from pre-established norms and engaged in a perpetual quest fornew rules within their works. Baudrillard’s insights into the evolution of science fiction reflect a broader postmodern reevaluation of reality as fragmented and simulacral. Furthermore, we address the so-called crisis of representation identified by Lyotard, challenging the realistic epistemology that views knowledge and art as mirrors of an external reality. By examining fragmented narration in literature, we propose a more inclusive approach to representing the multifaceted nature of reality. This article contributes to the understanding of postmodernism, highlighting its significance in redefining cultural expressions and our approach to knowledge and representation.
