Plainly speaking, there are two ways of learning wisdom. One way is that a person drinks to excess, then falls down in the mud, and then the police take him to the police station. 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 still does not learn. The other way of learning is that a young man in the street sees a drunken man and sees how terrible it is to be in this position; he learns from that. That is stealing the butter.
