Postmodernism refers to a break from modernity and the Enlightenment ideals of progress, rationality, and absolute truth. It emerged in the late 20th century across various disciplines and has proliferated into multiple, sometimes incompatible meanings. Key themes of postmodernity include questioning how culture, identity, and meaning are constructed; skepticism of grand narratives and universal ideals; and recognizing the influence of technology and media on society. While there is no single definition, postmodernism broadly critiques modernity and proposes new ways of understanding the world that acknowledge uncertainty and temporary meanings over absolute truths.
