When I was much younger and even more foolish than I am today, I had trouble saying three simple words: “I don’t know.” Instead, I had a view about everything. And I was right about everything, of course. I was certain of it.
As the years have gone by, I find that I’m certain of fewer and fewer things. I find that there are a few root-level “first things” that I’m sure of, but there aren’t many things outside of those few principles that I can say I know with certainty.
The list of things I proclaim as “truth” shrinks all the time. I have more questions and fewer answers, partly because I’ve seen myself be wrong so many times and partly because I see that the world is far more complex than I realized even a few years ago.
So the idea of asserting so many opinions as absolute fact seems strange to me now. It feels jarring. I wonder if the certainty I expressed about so many things when I was younger was as annoying to others then as it is to me when I see it in others today.
I find that both science and Christian faith offer insights and truths to me about certain things, but scientists go wrong when they go beyond what they reasonably know to assert things they don’t know — and Christians go wrong when they claim certainty about things where Jesus and scripture are silent.
Why do people assert things as fact when they’re not in the position to know those things? I think it’s because they’re afraid of uncertainty. They don’t mean to “fill in the blanks” when they don’t know things, but they do, because they’re terrified of not knowing. Christian singer Pat Terry addressed this tendency in a song called “Nothing I Say.” He wrote:
Ron Paul isn’t a racist, but the old newsletters need a credible response
Certainty leaves us unwilling to change beliefs when we’re wrong
Bias, incompetence or manipulation? Things aren’t always what they seem
Finding your own authentic voice is riskier than copying everybody else
Traits that lead to great romance don’t always make right partners
How much can human heart take when inner winter lasts forever?
Chance encounter with woman leaves me grateful for my health
Take time to give honest praise, even when it’s just about a dog
Honesty, wisdom and insight teach that we have to live with uncertainty
