Even if I am 1% correct there remains the effect of the subconscious to be known to be able to say 'there is free choice'.
As I said, I consider freedom within what we
can do. There's also an effect to my decisions in the beach from the fact that I can't breathe underwater. If I could, I might dive deeper. But I can't, so I don't, and I don't consider that a limitation of my freedom.
That is not how most people understand free will.
I am not here to defend such or such definitions of free will so this particular subject has little importance to me.
After reading a bit on compatibilism, I consider you may be right. I certainly agree that we need a consistent definition of free will for it to have any signification. Doing what we want according to our preferences looks like 'free enough' to me.
How can i choose something if not using my preferences to decide?
There has to be 1 single choice that is prefered in every single moment.
Well, if it were not, then choosing wouldn't make sense or be useful.
Imagine you have three possible options: A, B and C.
You prefer B and C over A.
How do you decide which one to pick now?
I would say you will have a preference for B over C, or C over B at this moment which will then allow you to choose.
How do you solve this problem if not this way?
I agree with your solution.
I don't understand. What do you mean by this?
I think that if you can affirm that the soul is deterministic no matter what happens, then determinism won't be falsifiable and so it will still be the dead-end.
I will choose according to my will. That is correct.
You still have to explain how something non-physical instantly grants itself the possibility of being not determined by past events nor indetermined.
It seems logically incoherent to me.
It's coherent as long as determination remains physical. Since I have brought the soul as a non-physical entity, then you can't attribute the soul physical causation. I have no deep knowledge in the workings of the soul, but I see no immediate reason to grant it's deterministic, which would be the option you seem to imply. It has agency because it's an agent, it acts, with its own will, ultimately granted by God.
Causation is something we have described in terms of physical entities, part of the physical universe, so I can't see why it would apply to the soul. When you are sitting down, relaxing, and a thought suddenly pops into your mind, is that caused by anything physical? I don't know.
