Knowing

One who knows not, and knows not he knows not, is a fool; shun him.

One who knows not, and knows he knows not, is simple; teach him.

One who knows, and knows not he knows,  is asleep, awake him.

One who knows, and knows he knows, is wise, follow him.

This is a quote made by Mr Soumitro Banerjee, my English teacher at school, in an 8th grade English class .

I hope you will forgive me for sacrificing gender sensitive language in favor of brevity and elegance.
