Men are four;
He who knows and knows not that he knows. He is asleep; wake him.
He who knows not and knows not that he knows not. He is a fool; shun him.
He who knows not and knows that he knows not. He is a child; teach him.
He who knows and knows that he knows. He is a king; follow him.

Were not attained by sudden flight,
But they, while their companions slept,
Were toiling upward in the night.

The trees are white with dust, that o'er their sleep Wave their broad curtains in the south-wind's breath, While underneath such leafy tents they keep The long, mysterious Exodus of Death.
