The good news about ignorance is that it sets us free from mental chains. Now, to be clear, what I’m talking about here is accepting and admitting our ignorance. This is essential if we want to actually know things, as opposed to making a show of knowing things. And I can tell you from personal experience that it really works. I gained the habit of admitting my ignorance (almost advertising it) back in the early 1980s, and that habit has helped me toward more understanding and discovery than I’d be able to itemize.
