A tale about Testing and Ignorance
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 unlearned. Teach him!
He who knows and knows not that he knows, is asleep. Awaken him!
He who knows and knows that he knows, is enlightened. Follow him!
An Arab Proverb quoted by
Isabel Lady Burton (1831-1896) in
"The Life of Captain Sir Richard F. Burton"
