We know so much. Whenever something happens in the world, we have opinions about it. We know where things have gone wrong. We know what is true and what is false. We know who can be trusted and who cannot. And we have solutions to it all. If only they'd listen.
When we have such knowledge, we might think there is not much more to learn. After all, we cannot learn what we already know. But perhaps there is conceit in our claim to knowledge. When we know in our hearts that our opinions are true, and that we have all the answers, we build a wall around ourselves. A wall that blocks other viewpoints. A wall that impedes learning.
Perhaps the key to wisdom is the admission that we don't know as much as we think we do. Real wisdom might sit not in our ability to strongly defend our preconceived opinions, but in our willingness to be proven wrong. This ability is not easily mastered. But if we can see the strength in admitting that our opinions may be wrong, we might find ourselves closer to achieving true wisdom.
