Good morning. Have you folks had a chance to read Maldacena's article in the November issue of Scientific American on "the illusion of gravity"? It has me thinking over the past few weeks and seemed relevant to a few points you were discussing.
In particular I found the point about the thickness of a string at the holographic boundry (without gravity) being the equivalent of the location of the particle in the '3D middle' (with gravity) mentally consuming.

I have also picked up a book called 'The Mind's I, Fantasies and reflections on self and soul' by DR Hofstadter and DC Dennett. It is an interesting compendium of writings on what consciouness might be and I found the excerpts from Richard Dawkins' 'The Selfish Gene' very interesting. Helped me pick up some new thoughts.

Glad to have found the site.
