You answer in good faith, and take up your hat and depart, closing the door of the good father's study behind you. But stop a moment, why do you close the door? You close the door because your reason tells you that otherwise the cold air outside will blow in and make the good father uncomfortable. You put your hat on, because your reason has not yet been applied to the problem of the cause of baldness. You step out onto the street, and when you hear a sudden noise, you step back onto the curbstone, because your reason tells you that an automobile is coming, and that on the sidewalk you are safe from it. So you go on, using your reason in a million acts of your life whereby your life is preserved and developed. And if anybody suggested that the fallibility of your reason should cause you to delay in front of an automobile, you would apply your reason to the problem of that person and decide that he was insane. And I say that just as there is insanity in everyday judgments and relationships, so there is insanity in philosophy, metaphysics and religion; the seed and source of all this kind of insanity being the notion that it is the duty of anybody to believe anything which cannot completely justify itself as reasonable. Nowadays, as ideas are spreading, the champions of dogma are hard put to it, and you will find their minds a muddle of two points of view. The Jewish rabbi will strive desperately to think of some hygienic objection to the presence of meat and butter on the same plate; the Catholic priest will tell you that fish is a very wholesome article of food, and that anyhow we all eat too much; the Methodist and the Baptist and the Presbyterian will tell you that if men did not rest one day in seven their health would break down. Thus they justify faith by reason, and reconcile the conflict between science and theology. Accepting this method, I experiment and learn that it improves my digestion and adds to my working power if I play tennis on Sunday. I follow this indisputably rational form of conduct--and find myself in conflict with the "faith" of the ancient State of Delaware, which obliges me to serve a term in its state's prison for having innocently and unwittingly desecrated its day of holiness!
