Hi Rareș Mircea, thanks for writing. In the context of your analogy, denying the existence of free will seems to me like denying the existence of water. Once the reality of water and free will is acknowledged, we can proceed to investigate the nature of water and free will. Investigating the nature of free will is what I’m trying to do here.

“…if defined as a supernatural ability to make different choices given the same exact state…”

I’m NOT defining free will as “a supernatural” ability, but as a property of the fabric of natural reality.
