[T]he writer’s role is not free from difficult duties. By definition he cannot put himself today in the service of those who make history; he is at the service of those who suffer it. Otherwise, he will be alone and deprived of his art. Not all the armies of tyranny with their millions of men will free him from his isolation, even and particularly if he falls into step with them. But the silence of an unknown prisoner, abandoned to humiliations at the other end of the world, is enough to draw the writer out of his exile, at least whenever, in the midst of the privileges of freedom, he manages not to forget that silence, and to transmit it in order to make it resound by means of his art.
