There is nothing random about free will - this is just confusing the issue.
Ok, so there are no random components - I'd agree.
I fully agree that "will" is purposeful and not random. The question is whether our conscious awareness has the freedom to choose which purpose to fulfil.
It's more about what is the nature of 'choice'. Given who you are at a given time, regardless of what's doing the choosing, a brain or a soul, it's dependent upon what's gone before: you've inherited (or been bequeathed?) an underlying character or nature, and experience has 'modified' that to make you who you are at a given point.
At that point, given who you are, is there any way for you to make a different decision than the one you do? In doing so would you not, in effect, be a different person than the one you are? It would require a different experience or nature to make different decision - it would require a different person.
The contention is that the choice has already been made sub consciously and we become aware of the choice after the event. But most people's perception is that their conscious awareness has the freedom to make the choice - and this is what I understand to be free will.
We are more than adequately aware, though, that our perception is limited and not always reflective of reality.
If our conscious awareness is just an emergent property of the material brain, then it will be entirely defined by our material brain and subject to the deterministic nature of material behaviour - hence no free will, and our perception that we have free will is an illusion.
Yes, but beyond that regardless of what it is that's 'choosing', in order for it to be 'will', it has to be determined by prior events.
But if our awareness does have the freedom to invoke a conscious choice of action, then conscious awareness must comprise of something which is not restricted by the deterministic nature of our material brain and must be more than an emergent property.
If it's not 'deterministic' - regardless of whether it's material or spiritual - then, by your own account, it's not will, it's random.
