So I don't see a 'slippery slope' problem that you seem to be arguing for here.-"DHW: As I said earlier, and in conjunction with Tony's comments, it seems to be a licence for people to believe whatever they want to believe."-This was dhw's comment. His background is all literary and the science of quntum mechanics, which I barely understand with my medical background, is well beyond what he can appreciate. He is right. His commnets will be a good guide to your layman's book to come. I'm also looking forward to it as your two layer approach is right on to help with understanding how much we can learn of the 'other side'.
