Very often a simple person has no reason, and he is fixed on his idea; and you may bring before him any reason, and yet he will not listen to it. He says, "That is what I believe; what the crowd believes, I do not care. If it is written in the scriptures, in history, if professors, doctors, scientists, priests, or clergy say it, I do not believe it." That becomes a kind of illusion, a kind of madness, because a person who believes in his reason independently of the crowd and of the authorities must be ready to understand the reason of another and must be simple enough to give up his reasoning when another person's reasoning appeals to him. <.p>
