He who Knows Not, and Knows Not that Knows Not,
but thinks he Knows, is a fool ... shun him!
He who Knows Not, and Knows that he Knows Not,
is a child ... teach him!
He who Knows, but uses not what he Knows,
is asleep ... wake him!
Oh! but he knows, and Knows that he Knows,
and uses what he Knows is a Leader ... follow him!
