This is what you CLAIM, right?
And, is EVERY thing you CLAIM IRREFUTABLY True, Right, Accurate, AND Correct?
'Free will' being cause or not caused has ABSOLUTELY NOTHING AT ALL to do with WHY 'free will' is, supposedly and allegedly, called 'free'.
Now, if there is some thing that is 'free of causation', then those who say, believe, or claim that there is some thing 'free of causation', then just TELL 'us' WHAT 'that thing' is, exactly.
If 'randomness' is the ONLY alternative to being 'free of causation', then just TELL 'us' of one 'random' event, which was supposedly ABSOLUTELY 'free of causation', then ALLOW 'us' to have a 'look at' 'that', and then ALLOW 'us' to DISCUSS 'that'. And, let 'us' SEE if there is ACTUAL 'randomness' and ABSOLUTE 'free of causation', or NOT.
I found there is NO, REAL, USE in making CLAIMS, here, without providing ACTUAL EXAMPLES.
By the way, 'free will' was CAUSED, EXACTLY LIKE ABSOLUTELY EVERY thing ELSE was CAUSED.
you human beings did NOT evolve to just 'one day' JUST SUDDENLY HAVE 'free will'. you were created to evolve to HAVE 'free will', from JUST CAUSES.
you would NOT LEARN HOW TO CHANGE 'your ways', for the better, if you could NOT LEARN FROM 'your MISTAKES', and it is 'your ABILITY' to 'make CHOICES' HOW you ALL can and do become BETTER. The ABILITY TO CHANGE is just what the 'free will' words have been meaning, and referring to, EXACTLY.
