Reading this whole thread, I'm interested to know what your thoughts on causality are. Do you have existing posts on the subject that I should re-read? I was under the impression you pretty much agreed with Pearl, but now that seems not to be the case.

By the way, Pearl certainly wasn't arguing from a "free will" perspective - rather, I think he'd agree with "there is no do() in physics" but disagree that "there is causality in physics".
