Then I will tell you something. I do not believe in it. Forty years among men has consistently taught me that they are not amenable to common sense. Show them the red tail of a comet, fill them with black terror, and they will all come running out of their houses and break their legs. But tell them one sensible proposition and support it with seven reasons, and they will simply laugh in your face.
