But the key is undoubtedly that freewill is a process. Noone would argue that freewill is an output, a "product", but rather the process that leads to an output.
Sure, it might entail some imagination (another process) to generate the "options", but the actual choice is arrived at through a process. And thus it is the process that is key.
If one has to choose between A and B, freewill is not the choice of A, or the choice of B, but in the way that choice is arrived at. What A and B are might influence that process, though.
But lets say A and B are options that "defy the laws of physics"?
Does me saying: "I can choose either between flying to the moon unaided, or swallowing mount Everest!" actually defy the laws of physics?
If I then say: "Well, I'll choose to fly unaided to the moon!" does that then defy the law of physics? I have appeared to demonstrate my "freewill" in doing so, in reaching this choice.
But no, I would certainly say not. Freewill is a process. It only when we try to make that choice
real that we realise that it must adhere to the laws of physics, and why such a choice is actually impossible.
I guess that we are fortunate to have sufficient capacity to generate mental simulations in which we can build a simulated universe in which the laws are different to reality. The same way a computer game can generate simulated worlds with utterly different physics to our own. But noone would be foolish enough to say that the computer is defying the laws of physics in doing so.
So freewill,
as a process is "real" the way any process is real: it is the reality of the interacting synapses, neurons, atoms, molecules etc.
But there is clearly no freewill
as a "product".
So the OP is, as you stated, doomed from the outset until it can overcome this blatant flaw in approach:
it is not what you choose from, but how you choose that matters.
And even QQ managed to admit that he has "
no dispute about 'process' being a biological function and must conform with the laws associated. None at all."
And if he said it then it must be right, eh?
