Lox - I see the problem here. My "I" is an illusion perceiving itself as an illusion perceiving itself as an illusion perceiving itself as an illusion perceiving itself as an illusion ad infinitum, whereas you are just self-obsessed ;-)

My original comment was really only a thought about how humanity might have originally developed consciousness (or self awareness, perhaps?) - what we may have done with it since is another kettle of fish altogether, possibly even a horse of a different colour. I hadn't got that far.. I expect quantum mechanics has the answer, but I don't have the right spanners.
