“A proper sense of proportion leaves no room for superstition. A man says, "I have never been in a shipwreck," and becoming nervous touches wood. Why is he nervous? He has this paragraph before his eyes: "Among the deceased was Mr. ——. By a remarkable coincidence this gentleman had been saying only a few days before that he had never been in a shipwreck. Little did he think that his next voyage would falsify his words so tragically." It occurs to him that he has read paragraphs like that again and again. Perhaps he has. Certainly he has never read a paragraph like this: "Among the deceased was Mr. ——. By a remarkable coincidence this gentleman had never made the remark that he had not yet been in a shipwreck." Yet that paragraph could have been written truthfully thousands of times.”
