He who knows not and knows that he knows not is ignorant... He who knows not and knows that he knows not is ignorant. Teach him.
He who knows not and knows not that he knows not is a fool. Shun him.
He who knows and knows not that he knows is asleep. Wake him.
He who knows nothing, knows nothing.
But he who knows he knows... He who knows nothing, knows nothing.
But he who knows he knows nothing knows something.
And he who knows someone whose friend's wife's brother knows nothing,
he knows something. Or something like that.
