Herzog could not say what the significance of such generalities might be. He was only vastly excited — in a streaming state — and intended mostly to restore order by turning to his habit of thoughtfulness. Blood had burst into his psyche, and for the time being he was either free or crazy. But then he realized that he did not need to perform elaborate abstract intellectual work — work he had always thrown himself into as if it were the struggle for survival. But not thinking is not necessarily fatal. Did I really believe that I would die when thinking stopped? Now to fear such a thing — that’s really crazy.
– Saul Bellow, Herzog
