Men are of four kinds:

 

1] a man who knows, and knows that he knows – this one is a scholar, so ask him questions;

 

2] a man who knows, and does not know that he knows – this one is forgetful, so remind him;

 

3] a man who does not know, and knows that he does not know – this one is an ignorant man, so teach him;

 

4] and a man who does not know, and does not know that he does not know – this one is a stupid man, so do not have anything to do with him.
