" He watched the pain's unsummoned appearance with a cold, detached curiosity; he said to himself: Well, here it is again. He waited to see how long it would last. It gave him a strange, hard pleasure to watch his fight against it, and he could forget that it was his own suffering; he could smile in contempt, not realizing that he smiled at his own agony. Such moments were rare. But when they came, he felt as he did in the quarry: that he had to drill through granite, that he had to drive a wedge and blast the thing within him which persisted in calling to his pity. "
