The imposible testimony: Celan in Derrida

This article wants to present some problems related to the testimony: the truthfulness of the testimony, the comparison of the methodic and scientific method (which require proofs) and the knowledge of testimony (that does not have proofs and is based on a bet on the faith and oath of what is testified), the impossibility of representing the irrepresentable after Auschwitz and the bet on keeping the memory in spite of the existing inability to represent what happened at concentration camps. These problems will be dealt through Celan's poetry, who speaks and gives his testimony with the purpose of preserving memory, without pretense of truth and representing the irrepresentable, against oblivion and artistic representations without limits; and through Derrida's bet because no one can testify for another.
