 Many of these critiques attack specifically the tendency to the "abandonment of objective truth" as the crucial unacceptable feature of the postmodern condition and often aim to offer a meta-narrative that provides this truth.Alex Callinicos attacks notable postmodern thinkers such as Baudrillard and Lyotard, arguing postmodernism "reflects the disappointed revolutionary generation of 1968, (particularly those of May 1968 in France) and the incorporation of many of its members into the professional and managerial 'new middle class'.It is best read as a symptom of political frustration and social mobility rather than as a significant intellectual or cultural phenomenon in its own right."
