And you must see the significance of "pre determined" over just "determined".
In this context there is no difference. You only want to make a distinction because you want to use "determined
by" as an excuse for not considering the determined
how question.
You want to say that choice are determined because they are determined
by the "conscious will of the human soul" (or some such meaningless nonsense) and hence avoid the whole question of
how this "conscious will of the human soul" makes its choice. It's either serious confusion or serious dishonesty on your part.
As I have explained - physical reactions are predictably pre determined, and in the purely materialistic scenario there can nothing but pre defined physical reactions - hence everything is entirely and predictably pre determined according to the laws of physics. If you see anything wrong with this logic, please point it out instead of just labelling it as wrong.
It's not that it's wrong, it's that
any non-random decision making system is subject to exactly the same logic. The system may not be physical and the laws may not be the laws of physics but, as long as you exclude any random element, everything must be just as (pre)determined.
That is why the 'physical' or 'material' is irrelevant to the logic.
But in writing this post, every letter I type is actively being determined by my conscious will. I am actively determining what I write, and this activation is occurring now as I write it. To try to presume that it was all predictably pre determined is nonsense.
Baseless assertion.
