“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 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.”
“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!”
“The wise man is one who, knows, what he does not know.”
“He who knows others is wise; he who knows himself is enlightened.”
“The fool doth think he is wise, but the wise man knows himself to be a fool.”
