Jean-François Lyotard was a key postmodern philosopher best known for his work “The Postmodern Condition.” He argued that grand narratives—universal explanations that legitimize power and knowledge—are no longer tenable in an age of diverse, fragmented experiences. Instead, Lyotard promoted the idea of multiple, localized narratives, emphasizing that knowledge is shaped by language games and social contexts. His work challenges the notion of objective, universal truth and encourages skepticism toward totalizing theories.
