To challenge and to cope with this paradoxical state of things, we need a paradoxical way of thinking; since the world drifts into delirium, we must adopt a delirious point of view. We must no longer assume any principle of truth, of causality, or any discursive norm. Instead, we must grant both the poetic singularity of events and the radical uncertainty of events. It is not easy. We usually think that holding to the protocols of experimentation and verification is the most difficult thing. But in fact the most difficult thing is to renounce the truth and the possibility of verification, to remain as long as possible on the enigmatic, ambivalent, and reversible side of thought.
