Yeah this is fair. An exaggerated imagine against an exaggerated image. I'll cop that. Still, I think Jameson was essentailly right in his intro to Lyotard's PC when he wrote that:
"Lyotard's affiliations here would seem to be with the
Anti-Oedipus of Gilles Deleuze and Felix Guattari, who also warned us, at the end of that work, that the schizophrenic ethic they proposed was not at all a revolutionary one, but a way of surviving under capitalism, producing fresh desires within the structural limits of the capitalist mode of production as such. Lyotard's celebration of a related ethic emerges most dramatically in the context of that repudiation of Habermas's consensus community already mentioned, in which the dissolution of the self into a host of networks and relations, of contradictory codes and interfering messages, is prophetically valorized.
...Lyotard's insistence on narrative analysis in a situation in which the narratives themselves henceforth seem impossible is his declaration of intent to remain political and contestatory; that is, to avoid one possible and even logical resolution to the dilemma, which would consist in becoming, like Daniel Bell, an ideologue of technocracy and an apologist for the system itself. How he does this is to transfer the older ideologies of aesthetic high modernism, the celebration of its revolutionary power, to science and scientific research proper. Now it is the latter's infinite capacity for innovation, change, break, renewal, which will infuse the otherwise repressive system with the disalienating excitement of the new and the "unknown" (the last word of Lyotard's text), as well as of adventure, the refusal of conformity, and the heterogeneities of desire."
Which is to say - as I read it - that the recourse to the paralogism (and the differned, after it) and so on is a
strategic initiative, one specifically tailored to the postmodern condition, and not some trans-historical maneuver designed to work at all times in all places. So there's a kernel of truth in Lyotards' own 'postmodernism', but it is, once again, tributary to the condition that 'preceded' him and to which he is responding in his own time and place.
