When Kafka allows a friend to understand that he writes because otherwise he would go mad, he knows that writing is madness already, his madness, a kind of vigilance, unrelated to any wakefulness save sleep’s: insomnia. Madness against madness, then. But he believes that he masters the one by abandoning himself to it; the other frightens him, and is his fear; it tears through him, wounds and exalts him. It is as if he had to undergo all the force of an uninterruptable continuity, a tension at the edge of the insupportable which he speaks of with fear and not without a feeling of glory. For glory is the disaster.
