That is,we are in a logic of simulation,which no longer has anything to do with a logic of facts and an order of reason.Simulation is characterized by a precession of the model of all the models based on the merest fact-the models come first, their circulation,obital like that of the bomb,constitues the genuine magnetic field of the event.The facts no longer have a specific trajectory,they are born at the intersection of models, a single fact can be engendered by all the models at once.
