In computerized societies, Lyotard w rites, knowledge ceases to have an end in itself and starts to be produced in order to be sold and consumed. Exchange becomes its ultimate goal: the introduc-tion of the computer and information technology defines not only a society but a condition at large and a stage of progress in which knowledge turns into a commodity. According to Lyotard, such a condition can be found “in the most highly devel-oped societies:”3 his argument underlies a notion of progress that the term “postmodern”—under-stood as what comes after the modern—already foregrounds. Modern and postmodern appear here as two stages of a process that is the outcome of science’s conflict with narratives: while trying to distance itself from the ground of narratives and “fables” that, given their fictional nature, are not compatible with scientific knowledge, science must nevertheless produce its own ground of legitimi-zation. Science “is obliged to legitimate the rules of its own game.”4 This novel discourse (that Lyotard identifies in philosophy) is what he calls a “met-anarrative.”
