Good people are good because they've come to wisdom through failure. These days people seek knowledge, not wisdom. If you wish to know the road up the mountain, ask the man who goes back and forth on it. To know is not to be wise.
Many men know a great deal, and are all the greater fools for it.
There is no fool so great a fool as a knowing fool. Without wisdom, knowledge is more stupid than ignorance. Seek what they sought. The heart of the wise man lies quiet like limpid water. The doors of wisdom are never shut.
