 The term “postmodern” came into the philosophical lexicon with the publication of Jean-François Lyotard's La Condition Postmoderne in 1979 (in English: The Postmodern Condition: A Report on Knowledge, 1984), where he employs Wittgenstein's model of language games (see Wittgenstein 1953) and concepts taken from speech act theory to account for what he calls a transformation of the game rules for science, art, and literature since the end of the nineteenth century. He describes his text as a combination of two very different language games, that of the philosopher and that of the expert. Where the expert knows what he knows and what he doesn't know, the philosopher knows neither, but poses questions. In light of this ambiguity, Lyotard states that his portrayal of the state of knowledge “makes no claims to being original or even true,” and that his hypotheses “should not be accorded predictive value in relation to reality, but strategic value in relation to the questions raised” (Lyotard 1984 [1979], 7).  The book, then, is as much an experiment in the combination of language games as it is an objective “report.”
