I have been out of town for a while and did not have time to take part in this discussion, but would like to jump back in.
My take on the question is that there is:
1. an ego-self that is aware of its own existence, history, and its participation in the world. It is produced by reiteration of the proto-self with current sensory data, memories and data processing functions.
2. a proto-self that is pure awareness since it lacks the autobiographical data of the ego-self. It is produced by structures in the brain that evolved long before self-consciousness and forms the basis for the higher functions that produce the ego-self.
3. a universe containing patterns of matter and energy that exist whether or not they are perceived by anyone. At least one planet in this universe produced sentient life through the natural processes of evolution.
If the universe does really not exist, why do we perceive it in such detail? Whence came the ideas that comprise it? How can a Big Mind exist without any structure to allow it to remember anything, think, or communicate with itself and its parts?
The universe has structure. Brains have structure. Thoughts have structure as energy patterns produced by arrays of organic molecules. I cannot imagine how a free-form Consciousness can exist without some kind of structure, whether it is composed of matter, energy, force fields, or some unknown substance.
Twyvel, consciousness could not be a reflected manifestation without something to manifest itself, something to reflect it, and something to observe it. You can't generate an argument with smoke and mirrors, then take away the smoke and mirrors and claim that your point remains, totally unsupported.
