great. thx for this.
I don't know (I've queued up to learn more, but still may not grock it :)) but this sounds like more quantum mind musings. Penrose and Hameroff are plugging away at this, but they seem very reluctant to open things up very much. They never address the "really hard problem of consciousness -- NDEs :)
-- eidit -- I take it back. I think Witten is politely saying that quantum consciousness is bunk.
BTW would love to get Carroll on Skeptiko if anyone would be willing to reach out.
Hi Alex ... Thanks for reply :-) That's what I got too about what he said re quantum consciousness. And then consciousness is just left undefined. And overall I also got that he was really subtle and honest on the whole issue and it was fascinating watching him put what be thought into words. Really, with Ed Witten, there's so much else going on in a mind such as his!
BTW, I just put in a request to Sean Carroll for an interview. Hope the reply's positive!
