Jean Baudrillard was a French philosopher who focused on the concepts of simulacra, truth, and hyperreality. He argued that in modern society, simulations and representations of reality have proliferated to such a degree that the distinction between real and not real has blurred, and we now live in a state of hyperreality constructed of simulacra rather than related to an actual reality. Baudrillard used examples like Disneyland and media representations of war to show how simulations and images have replaced and constructed our perceptions of reality. He was critical of the idea of single, objective truths and argued that in postmodern society we should view all truths with skepticism.
