Considering the animal brain, emotionally driven person has free volition; there is no doubt that we have control over our judgements, opinions, beliefs, values, and the like. We have general control over our movements, up to the physical limits, although it may not be precise.
The difference between free volition and free will lies in whether we have control over our desires, delusions, and aversions. Totally rational people (Spoc like) have control over their desires, while the remainder of us have less control, but some management ability of our desires. Those of us who do not have control but only some influence over our desires are hurled along by our desires, not down a planned course but from one desire to the next. It is in satisfying those desires rather than ignoring them that this eating problem seems to arise in me and others.
Could this be one more key in understanding my problem? or just take me one step closer. Perserverence. I need to see if this worm hole goes somewhere. So next, how does one dissipate a desire once it has formed?
Now the kicker. Free will may be a learned characteristic. Can we learn to say no to all the shit on offer? All the food, drugs, bad habits, all forms of addiction, bad behavior, and learn to live a frugal and prudent life? The frugal part will be the most difficult within the cities, if we have an average income or better.
