The meeting of extremes is never clearer than in the case of moral and intellectual strength and weakness.

Context

“To be poor is to be contemptible, to be very poor is worse still, and so on; but to be actually at the point of death through poverty is to be sublime. So “when weakness is utter, honour ceaseth.” [The Righteous Man, p. 390, post.] iii The meeting of extremes is never clearer than in the case of moral and intellectual strength and weakness. We may say with Hesiod “How much the half is greater than the whole!” or with S. Paul “My strength is made perfect in weakness”; they come to much the same thing. We all know strength so strong as to be weaker than weakness and weakness so great as to be stronger than strength.” source
