This founding essay of the postmodern movement argues that knowledge—science, technology, and the arts—has undergone a change of status since the 19th century and especially since the late 1950s.

Many definitions of postmodernism focus on its nature as the aftermath of the modern industrial age when technology developed dynamically. In The Postmodern Condition Jean-Francois Lyotard extends that analysis to postmodernism by looking at the status uf science, technology, and the arts, the significance of technocracy, and the way the flow of information and knowledge are controlled in the Western world. Lyotard emphasized language; the world of postmodern knowledge can be represented as a game of language where speaking is participation in the game whose goal is the creation of new and ever-changing social linkages.
