“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. ”

“Doubt was much more energy efficient than conviction.”

“Let me propose that if your beliefs or convictions matter more to you than people—if they require you to act as though you were a worse person than you are—you may have lost perspective.”

“Our greatest challenge today...is to couple conviction with doubt. By conviction, I mean some pragmatically developed faith, trust, or centeredness; and by doubt I mean openness to the ongoing changeability, mystery, and fallibility of the conviction.”

“I ought not to doubt the steadiness of your affection, yet such is the inconsistency of real love, that it is always awake to suspicion, however unreasonable; always requiring new assurances from the object of its interest, and thus it is, that I always feel revived, as by a new conviction, when your words tell me I am dear to you; and, wanting these, I relapse into doubt, and too often into despondency.”

“I may not be sure if monsters exist, but I’d rather live my life in doubt than be persuaded by a real experience of one.”
