Once more:
I have never denied that our freedom to choose is not deterministic.
But -
What drives our consciously made choice?
What is the source which guides conscious manipulation?
Where does conscious control emanate from?
These are all determined by physical activity in the human brain, but what initiates this activity?
The obvious answer is "you".
If these were just inevitable consequences of previous physically controlled cause and effect reactions, the entity which is "you" becomes superfluous, being just another link in the endless chains of cause and effect.
But the truth is that you are much, much more than a physical link in the chain.
I'm glad that you agree that our freedom to choose is squarely based on the theory that everything that happens must happen as it does and could not have happened any other way. So, no buts at all needed.
However to answer your questions:
What drives our consciously made choice?
Evidence suggests our brains.What is the source which guides conscious manipulation?
Evidence suggests our brains.Where does conscious control emanate from?
Evidence suggests our brainsThese are all determined by physical activity in the human brain,
Good, we agree but what initiates this activity?
Evidence suggests our brains.The obvious answer is "you".
Well, as I regard 'me' as basically the result of activity within my brain, I haven't any reason to disagree with you.If you have another explanation for what is the source of 'me' then I am willing to listen. However if your explanations simply take the form of your last sentence(i.e. an assertion) then please don't bother, as I find unevidenced assertions to be rather pointless. I would require reasoned and logical arguments, backed up with solid evidence to convince me.(Put it down to my brain state). So far, as far as I can see, you have produced little in the way of logic or reason, and certainly no evidence, for the existence of this soul of yours.
