What a great essay your 2010 "Theory of Everything" is! I have no idea how I managed to miss that one on your site-- probably because I was just searching for your Heart-related stuff, I guess.
I'd always thought the causation chain to be a bit of balderdash because I misunderstood its purpose. I thought it was trying to describe reality, and you've now helped me to see that I was wrong about that. I'm excited to re-examine the chain with the new glasses you've given me and spend some time reflecting on it. Thanks so much, that was really well done. Looks like I'll need to check up on Sue Hamilton, too, as I was unfamiliar with the name.
