Postmodernism is an intellectual stance or mode of discourse characterized by skepticism towards scientific rationalism and the concept of objective reality. It questions the "grand narratives" of modernity, rejects the certainty of knowledge and stable meaning, and acknowledges the influence of ideology in maintaining political power. Objective claims are dismissed as naïve realism, emphasizing the conditional nature of knowledge. Postmodernism embraces self-referentiality, epistemological relativism, moral relativism, pluralism, irony, irreverence, and eclecticism. It opposes the "universal validity" of binary oppositions, stable identity, hierarchy, and categorization.
