You will find scientists who will tell you — and they deeply believe it — that we’re quantifiable. We are knowable. That if I can take a high enough resolution picture of all of you — not just your outsides, but your genes, your DNA, all the way down to your atoms — I can know everything about you and everything that you will be. There are people who believe this. And what this tells me is, no. No! All the way down, to the bottom of our thoughts, there’s just more mystery.
