Abstract
We try to explore here the Derridean concept of "possibility." Such a concept has no contraries. It does not oppose effectivity or necessity, or even impossibility, but stays what it is in any case: possible. Trying to negate it or to contradict it only leads to denial. To Derrida, this strange status of possibility is addressed as the question of faith as such, as it appears in "Faith and Knowledge." Every belief is always, at its foundation, belief in the possibility of a completely different history altogether, in what Derrida calls the "utterly other chance." Is deconstruction the legible form of this otherness?
