Because one day of thanksgiving isn't enough (7 of 7)
On the final day of my week of thanksgiving, and, in fact, every day, I'm thankful for the things I don't know yet. And also for the things that we, collectively, don't know yet. I'm excited by the discovery process, by the opportunity to learn and seek out new bits and pieces of knowledge and experience, but also by the ongoing cycle of learning and unlearning that we all, individually and as a group, go through. And I'm always unreasonably glad when some new thing that we thought we knew about the world turns out to be wrong, just because it keeps us on our toes.
As Tommy Lee Jones's character in Men in Black says,
A person is smart. People are dumb. Everything they've ever "known" has been proven to be wrong. A thousand years ago everybody knew as a fact, that the earth was the center of the universe. Five hundred years ago, they knew it was flat. Fifteen minutes ago, you knew we humans were alone on it. Imagine what you'll know tomorrow.
