The document discusses postmodern theorists Jean Baudrillard, Fredric Jameson, and Jean-François Lyotard. It outlines Baudrillard's theory of hyperreality, in which the distinction between reality and simulation is blurred. Jameson believed that postmodernism is driven by consumer capitalism and results in a loss of historical depth and reality. Lyotard argued that the idea of truth needs to be deconstructed to challenge dominant narratives.
