“What Steve meant by this, I think, is that the world is unfathomably complex. To believe we have mastered it in all respects — that our angle of vision on matters like politics, philosophy and theology is just right all the time — is ridiculous. This doesn’t mean one ought to live in a state of perpetual doubt and uncertainty. If we did, we could never speak up for justice and moral truth. It does mean, however, that we’re aware that what we know is at best incomplete. “We see through a glass darkly” is how St. Paul put it in one of his letters to the Corinthians: We know only in part.
My point is not that humility is uniquely available to Christians; it is simply that Christian teaching and tradition affirm its importance.
Humility is a sign of self-confidence; it means we’re secure enough to alter our views based on new information and new circumstances. This would be a far more common occurrence for many of us if our goal was to achieve a greater understanding of truth rather than to confirm what we already believe — if we went into debates wanting to learn rather than wanting to win.”
“Certitude can easily become an enemy of tolerance but also of inquiry, since if you believe you have all the answers, there’s no point in searching out further information or making an effort to understand the values and assumptions of those with whom you disagree. It’s worth noting, too, that our checks-and-balances system of government assumes that none of us has all the answers and therefore no single person should be trusted with complete authority.”
