“He who knows not, and knows not that he knows not,is a fool; shun him.He who knows not,and knows that he knows not, is a student; Teach him.He who knows,and knows not that he knows,is asleep; Wake him.He who knows,and knows that he knows,is Wise; Follow him.”
“He Who Knows And Knows That He Knows Is A Wise Man - Follow Him;He Who Knows Not And Knows Not That He Knows Not Is A Fool - Shun Him”
“He who knows others is wise; he who knows himself is enlightened.”
“The wise man is one who, knows, what he does not know.”
“He who knows best knows how little he knows.”
“The fool who knows his folly Becomes wise by that fact.But the fool who thinks he's wise - He's called 'a fool' indeed!”
