When I say free will, I mean the freedom to make an unimpeded free choice between two or more things. That type of free choice is completely incompatible with omniscience & omnipotence.
Cieza, I believe this your contention:
if my actions (i.e. choices) are 100% predictable
then my actions are not a product of free will.
(I must admit, I haven't read through this whole thread, so forgive me if I'm missing your point.)
My contribution to the discussion would be that it depends on why my actions are 100% predictable. If it's because a time traveller with access to the future simply saw the choices I would make, I would still feel confident that I have free will. If it's because a brilliant psychologist wrote a CaptianJoy algorithm that could make the same choices I make, I would seriously doubt free will.
My impression is that if there exists an entity that is omniscience and omnipotence, then both bases are covered. And, I must doubt my free will, or the existence of omniscient and omnipotent being(s).
I have heard/read (not bad) arguments that free will does not exist. However, I
feel like I have free will. (I concede the belief in free will is not rational.) So now I, as a Christian, have a problem: how to reconcile my belief that I have free will with my belief in the Christian God.
Personally, I'm in the "cogito ergo sum" (René Descartes "I think, therefore I am") camp. To me, the existence of free will is one of the stronger ontological arguments for God (though not sufficient to lead to the Christian God). Free will by its very nature is supernatural--it means I have the ability of action that is not the direct result of prior stimuli. Once I acknowledge the existence of a supernatural, the djinni is out of the bottle and the existence of a supernatural God becomes possible. (I may be playing fast and loose with the definition of "free will", but I think you get my meaning.)
Of course, we still haven't reconciled the problem of my free will and an omniscient and omnipotent god. As I see it, there are multiple possibilities:
- God is not omniscient and omnipotent. For an example of this type of god (or more accurately, demiurge) google "God as a game designer".
- We do not have free will. (Entirely possible.)
- We have a semantic argument. E.g. Free will is behavior that is impossible to predicted vs. Free will is behavior that is divorced from purely materialistic phenomena. The first definition is incompatible with omniscient and omnipotent being(s), the second is not.
