How to confront a disaster?

Jean-Pierre Dupuy's recipe for confronting a disaster (ecological, natural, political, personal, etc.) as summarized by Slavoj Žižek: "We should first perceive it as our fate, as unavoidable, and then, projecting ourselves into it, adopting its standpoint, we should retroactively insert into the past (the past of the future) counter-factual possibilities ("If we had done this and that, the calamity that we are now experiencing would not have occurred!") upon which we then act today. We have to accept that, at the level of possibilities, our future is doomed, that the catastrophe will take place, that it is our destiny -- and then, against the background of this acceptance, mobilize ourselves to perform an act which will change destiny itself and thereby insert a new possibility into the past. Paradoxically, the only way to prevent the disaster is to accept it as inevitable. For Badiou, too, the time of the fidelity to an event is the futur antérieur: overtaking oneself vis-à-vis the future, one acts now as if the future one wants to bring about were already here" (Slavoj Žižek, First as Tragedy, Then as Farce [London: Verso, 2009], 151).
