“One who knows and knows that he knows…His horse of wisdom will reach the skies.One who knows, but doesn’t know that he knows…He is fast asleep, so you should wake him up!One who doesn’t know, but knows that he doesn’t know…His limping mule will eventually get him home.One who doesn’t know and doesn’t know that he doesn’t know…He will be eternally lost in his hopeless oblivion!”
