He Keeps Quite

Painting by Gonzales Coques (c.1650)

Generally people who know little speak a great deal, and people who know a great deal speak little. It is easy for an ignoramus to find everything he knows important and to tell it to everyone. But a well-informed man does not easily open up his repertoire. He would have too much to say, and he sees yet more to be said after he has spoken. He keeps quite.
