If you see a man who does not know and does not know that he does not know, Shun him, He is a fool.

If u see a man who does and does not know that he knows,Wake him up He is asleep. And if you see a man who knows and knows that he knows,follow him,he is wise. It is good to be wise………..

If you see a man who does not know and knows that he does not know, Teach him he is a child.
