The fool is thirsty in the midst of water

He who knows not and knows not he knows not: he is a fool - shun him. He who knows not and knows he knows not: he is simple - teach him. He who knows and knows not he knows: he is asleep - wake him. He who knows and knows he knows: he is wise - follow him.

He who conceals his disease cannot expect to be cured
