I could be wrong about pretty much anything. What I don’t know so outweighs what I do that my actual knowledge appears as little more than a small raft on an ocean of ignorance. I suffer no shame admitting this unflattering fact, not only because there’s never any shame in acknowledging the truth, but also because everyone else is in the same boat. Our ignorance-​-​what we don’t know-​-​always and enormously outweighs our knowledge. It’s true of even the smartest and most educated.
