"Doubt requires more courage than conviction does, and more energy; because conviction is a resting place and doubt is infinite – it is a passionate exercise. You may come out of my play uncertain. You may want to be sure. Look down on that feeling. We’ve got to learn to live with a full measure of uncertainty. There is no last word. That’s the silence under the chatter of our time. "
— John Patrick Shanley (Doubt: A Parable)
