Jean-François Lyotard

"Knowledge is and will be produced in order to be sold, it is and will be consumed in order to be valorised in a new production: in both cases, the goal is exchange."

"If we wish to discuss knowledge in the most highly developed contemporary society, we must answer the preliminary question of what methodological representation to apply to that society."

"Scientific knowledge is a kind of discourse."

"What is required of a working hypothesis is a fine capacity for discrimination."

"On the other hand, in a society whose communication component is becoming more prominent day by day, both as a reality and as an issue, it is clear that language assumes a new importance."

"…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?"
