your posting is very interesting for me: the I as a degenerative function on a neurological basis. Do you have more links or ressources for this thesis?
I also like the idea of a software evolution, as Daniel Dennett calls it. Do you know about memetics and especially the ideas from Susan Blackmore, e.g. the Selfplex?
May the neurological and the memetic approach can be integrated to explain the origin in a more detailed way?
The connection between fear and control is very essential to the development of our social structures. Power and control are the basic forces which form our societies and the history of our social relations. All "advanced" societies had a very clear power structure and I think that fear of inner or outer enemies was a very important source to keep this structure working. But where does the fear come from? Do Animals have fear in the way humans have? When did humans develop this special kind of fear?
Probably best to check out my web site http://www.kaleidos.org.uk
save repeating whats already available. Yes aware to some degree of Blackmore, Dawkins etc. I see the whole thing as the as the product of a deluded and limited state of mind ie the phenomena not the theory, though of course same applies.
Fear is a response to increasing loss of function and an inability to experience or understand the incomprehensible/indeterminate world we inhabit/are. So we create systems structure ideas to subsititute for experiential reality. Anything that challenges our contrived sense of self/identity is ignored suppressed etc.
