Who's the more foolish, the fool, or the fool who follows him?

I came across this Persian proverb and thought it a good thing to consider with regard to leadership and following quality people, in all categories of life (ecclesiastical, political, familial, etc.).

He who knows not, and knows not that he knows not, is a fool;
shun him.

He who knows not, and knows that he knows not, is a child;
teach him.

He who knows, and knows not that he knows, is asleep;
wake him.

He who knows, and knows that he knows, is wise;
follow him.
