Not only can people be led astray, most people are. If the devout Christian is right, then committed Hindus and Jews and Buddhists and atheists are wrong. When so many groups disagree, the majority must be mistaken. And if the majority is misguided on just this one topic, then almost everyone must be mistaken on some issues of great importance. This is a hard lesson to learn, because it is paradoxical to accept one’s own folly. You cannot at the same time believe something and recognize that you are a mug to believe it. If you sincerely judge that it is raining outside, you cannot at the same time be convinced that you are mistaken in your belief. A sucker may be born every minute, but somehow that sucker is never oneself.
