Plainly speaking, there are two ways of learning wisdom. The one way of learning wisdom is that a person goes and drinks to excess, and then falls down in the mud, and then the police take him to the police station, and when he recovers from his drunkenness he cannot find his clothes and he is horrified at his own appearance. This makes him realize what he has done. This is one way of learning, and it is possible that he does not learn. The other way of learning is that a young man is going along the street; he sees a drunken man, and sees how terrible it is to be in this position; he learns from that. That is stealing the butter.
