One of my favorite movies is "Doubt." It is based on the play of the same name by John Patrick Shanley. In his introduction to the play, Shanley has the following commentary about the virtue of doubt:
"There's a symptom apparent in America right now. It's evident in political talk shows, in entertainment coverage, in artistic criticism of every kind, in religious discussion.
We are living in a culture of extreme advocacy, of confrontation, of judgment and of verdict. Discussion has given way to debate. Communication has become a contest of wills. Public talking has become obnoxious and insincere. Why? Maybe it's because, deep down under the chatter, we have come to a place where we know that we don't know ... anything. But nobody's willing to say that.
What is doubt? Each of us is like a planet. There's the crust, which seems eternal. We are confident about who we are. If you ask, we can readily describe our current state. I know my answers to so many questions, as do you. What was your father like? Do you believe in God? Who's your best friend? What do you want? Your answers are your current topography, seemingly permanent, but deceptively so. Because under that face of easy response, there is another You. And this wordless Being moves just as the instant moves; it presses upward without explanation, fluid and wordless, until the resisting consciousness has no choice but to give way.
It is doubt, so often experienced initially as weakness, that changes things. When a man feels unsteady, when he falters, when hard-won knowledge evaporates before his eyes, he's on the verge of growth. The subtle or violent reconciliation of the outer person and the inner core often seems at first like a mistake. Like you've gone the wrong way and you're lost. But this is just emotion longing for the familiar. Life happens when the tectonic power of your speechless soul breaks through the dead habits of the mind. Doubt is nothing less than an opportunity to reenter the present.
There is an uneasy time when belief has begun to slip, but hypocrisy has yet to take hold, when the consciousness is disturbed but not yet altered. It is the most dangerous, important and ongoing experience of life. The beginning of change is the moment of Doubt. It is that crucial moment when I renew my humanity or become a lie.
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."
