Sorry, I could not understand your argument. However, I am not suggesting you are not communicating well - I probably do not know enough to make sense of your answer. My point was this: I believe that a significant fraction of well-educated people believe that when a human makes any kind of decision, the "cause" is the complex outworking of the laws of physics, as manifested in that person's brain. In short, there is no "me" making a decision - the decision is simply the outworking of the laws of physics at work in my brain.
Now I am not suggesting that the mainstream scientific establishment explicitly promotes such a view, but I suggest it is nevertheless held by many people. I, for one, do not believe it. I believe that the present models of nature we have (quantum physics, atomic theory, relativility, Newtonian mechanics, etc.) are essentially incomplete and / or have a built-in world-view bias against
the possibility that there are such things as truly "free" agents at work in the universe. Of course, this is just my hunch - I do not think I can make any kind of solid argument.
