Once the mirror is broken, nothing remains which can help us to answer the questions of our time. Absurdism, like methodical thought, has wiped the slate clean. It leaves us in a blind alley. But, like methodical doubt, it can, by returning upon itself, open up a new field of investigation, and the process of reasoning then pursues the same course. I proclaim that I believe in nothing and that everything is absurd, but I cannot doubt the validity of my proclamation and I must at least believe in my protest. The first and only evidence that is supplied to me, within the terms of the absurdist experience, is rebellion. Deprived of all knowledge, incited to murder or to consent to murder, all I have at my disposal is this single piece of evidence, which is only reaffirmed by the anguish I suffer. Rebellion is born of the spectacle of irrationality, confronted with an unjust and incomprehensible condition. But its blind impulse is to demand order in the midst of chaos, and unity in the very heart of the ephemeral. It protests, it demands, it insists that the outrage be brought to an end, and that what has up to now been built upon shifting sands should henceforth be founded on rock. Its preoccupation is to transform. But to transform is to act, and to act will be, tomorrow, to kill, and it still does not know whether murder is legitimate. Rebellion engenders exactly the actions it is asked to legitimate. Therefore it is absolutely necessary that rebellion find its reasons within itself, since it cannot find them elsewhere. It must consent to examine itself in order to learn how to act.
