He was dimly angry with himself, he did not know why. It was that he had struck his wife. He had forgotten it, but was miserable about it, notwithstanding. And this misery was the voice of the great Love that had made him and his wife and the baby and Diamond, speaking in his heart, and telling him to be good. For that great Love speaks in the most wretched and dirty hearts; only the tone of its voice depends on the echoes of the place in which it sounds. On Mount Sinai, it was thunder; in the cabman's heart it was misery; in the soul of St John it was perfect blessedness.
