Dan Dennett talks about philosophical zombies who are exactly like people except for one item, usually consciousness, so how can anyone tell the difference?
When I am in one of those eating stages, his description is almost exactly what it is like, I am doing it but I am not in control; I cannot stop; it is a form of mental dysfunction. All I can do is distract myself, perhaps delay, escape, of use alternative activity where food is not available. There does not seem to be any available help offered beyond drawing in a concept of something more powerful myself and using that to control the self. One fictional mental object to control the wild mind of uncontrol. Do some portion of the population have a portion of the mind that is beyond our control, and I am part of that portion of the population?
We have control over part of our consciousness, only part. But is there part also that we have no control over, and the short answer is yes, most of it. So what causes this vacillation between that part of eating in which we have control and that part which we have no control? I do not understand.
What pushes me over the edge? Available food is one item, if not the main item. Once started, I do not stop until all food is gone. That is a problem. I cannot go with no food. but it must be metered, doled out in small quantities... more later
