Hope, Anger & Courage

Radical adult educator Michael Newman writes extensively about anger in his book Teaching Defiance; distincting it from dismay and frustaration, and how to focus and use anger creatively, or what's the difference between anger and rage? But he does not mention St. Augustine to whom the following quote is attributed: "Hope has two beautiful daughters. Their names are anger and courage; anger at the way things are, and courage to see that they do not remain the way they are."
