Very often those who think that they can correct someone, that they can teach someone, that they can guide a person, that they can direct someone, are apt to forget that they may do quite the wrong thing. If a thief was told by his uncle not to steal, not to go and do his work and if he was held back, that only means that he would go and do it the next week. But if he goes and robs, if he is arrested by the police, if he is taken to prison and stays there for three years, then he has learned his lesson. His uncle could not teach him; it is life, it is circumstances that must teach him. It is the experience through which he has to go that teaches man.
