Two prisoners gazed out from behind bars;
One saw the mud, the other saw the stars.

He drew a circle to keep us out--heretic, rebel, a thing to flout;
But love and I had the wit to win, we drew a circle that took him in. 

He who knows not and knows not that he knows not is a fool;
But he who knows not and knows that he knows not is wise
Because then he is able to do something about it.
