There is still another picture to be seen: that of the foolish and the wise. The foolish man is ready to teach you without a moment's thought, ready to correct you, ready to judge you, ready to form an opinion about you. But the wiser a man is the more diffident he is to form an opinion about you, to judge you, to correct you. What does this mean? It means that whatever man possesses in a small degree he thinks he has much of, but when he possesses more he begins to feel the need and the desire for perfection, for completion.
