Jean-François Lyotard said this quote

…is postmodernity the pastime of an old man who scrounges in the garbage-heap of finality looking for leftovers, who brandishes unconsciousnesses, lapses, limits, confines, goulags, parataxes, non-senses, or paradoxes, and who turns this into the glory of his novelty, into his promise of change?

~ Jean-François Lyotard

Knowledge [savoir] in general cannot be reduced to science, nor even to learning [connaissance]. Learning is the set of statements which, to the exclusion of all other statements, denote or describe objects and may be declared true or false. Science is a subset of learning. It is also composed of denotative statements, but imposes two supplementary conditions on their acceptability: the objects to which they refer must be available for repeated access, in other words, they must be accessible in explicit conditions of observation; and it must be possible to decide whether or not a given statement pertains to the language judged relevant by the experts.

~ Jean-François Lyotard

Are we, intellectual sirs, not actively or passively 'producing' more and more words, more books, more articles, ceaselessly refilling the pot-boiler of speech, gorging ourselves on it rather, seizing books and 'experiences', to metamorphose them as quickly as possible into other words, plugging us in here, being plugged in there, just like Mina on her blue squared oilcloth, extending the market and the trade in words of course, but also multiplying the chances of jouissance, scraping up intensities wherever possible, and never being sufficiently dead, for we too are required to go from forty to the hundred a day, and we will never play the whore enough, we will never be dead enough

~ Jean-François Lyotard

A new problem appears: devices that optimize the performance of the human body for the purpose of producing proof require additional expenditures. No money, no proof - and that means no verification of statements and no truth. The games of scientific language become the games of the rich, in which whoever is the wealthiest has the best chance of being right. An equation between wealth, efficiency, and truth is thus established.
