The words physical and predetermined are entirely relevant because our knowledge of physically predetermined reactions on material elements is entirely predictable and applicable to the functionality of a material brain.
FFS Alan, how many more times? Every now-and-then it seems to sink in that you have a problem with logic, not physics, then off you go again with your pointless "predetermined" and "physical" as if it's never happened.
Once again: either the mind is a
deterministic system or not. That's a question that is independent from the question of whether minds are physical or not - it applies in either case.
Either we make choices entirely because of the pre-existing circumstances (internal and external) or not (which means there is some randomness).
There is no assumption of a physical mind in those questions.The concepts of consciously driven choices and control are totally incompatible with this materialist scenario.
Baseless assertion (again).
We do not have the same knowledge of spiritual determinism...
There aren't different types of determinism - adding the word "spiritual" means nothing - the same logical questions (above) apply. It's totally dishonest of you to pretend that they are based on the physical and that making the mind "spiritual" makes them go away.
The only way you can avoid them is by saying that you don't think logic (just logic, not "physical" logic) applies in the magic world of the soul. If you're prepared to abandon logic, that's fine but don't pretend that you aren't, that it's to do with the physical, or that you have any logic to back up your point of view.
...but the evidence of its existence lies in our ability to make consciously driven choices...
This is tantamount to lying. Every single conjecture about the mind attempts to explain our experience - it's simply dishonest to pretend that only yours can do so (especially as yours is
logically impossible).
A responsibility which can't be wholly attributed to the uncontrollable laws involved in physical determinism.
Baseless assertion (again).
