So please explain how you can introduce consciously driven control into a closed system entirely under the control of the physically pre defined events of cause and effect?
Why can you not accept that human willpower can invoke a choice from within its conscious awareness by interacting with the physical brain?
Because that makes no sense, that is why. Choices are made by a brain, we do not interact with a brain to tell it what choices to make. Brains evolved to make optimal choices. The idea that brains need another brain to tell them what choices to make is both bizarre and baseless. There is no evidence to support such a notion and it is logically incoherent implying a regress. Conscious awareness is not a separate thing to a brain, it is produced by brain functioning to better prioritise awareness, but it is not a separate thing to that which produces it.
You seem to have a mental blockage around the concept of 'physical'. There isn't a separate domain of logic for things that are 'physical'. Two plus two will equal four irrespective of the nature of the things being added. If someone on my team makes two suggestions for improvements and another guy makes two suggestions, then we have four suggestions. If I buy two apples from one stall and another two from another stall, then I will have four apples. The fact that apples are 'physical' does not alter the logic and we cannot deny the logic of the situation by the claim '
but they are physical'. That is just a trivial ploy to try to deny the underlying truth.
You seem to have a mental blockage around the concept of 'control'. I can control my hands and arms by willing them to move. Likewise an elephant can control its trunk, a more complicated business in terms of the neurology required. If brains alone were insufficient to do the translation of desire and intention into motor action then every creature on the planet would be dead already, being totally immobile, unable to will their limbs to move. The fact that humans can do this derives from the fact that great apes can do this, and so on. What we cannot control is the subliminal preconscious functioning that gives rise to desires and intentions in the first place. I cannot look up at the sky and choose to experience it as green, we have no control over that. I cannot put a strawberry in my mouth and choose to find it tastes of garlic, I have no control over that. We have no control over the fundamental primitives of how we interact with the wider cosmos, functioning at these base levels is entirely consistent with a deterministic account of nature. Concepts of 'control' and 'freedom' at higher levels of biological complexity are useful concepts at those levels of emergence, they are essentially
feelings produced by mind at the interface between thoughts and actions and although we live our lives almost exclusively in those higher domains of emergence does not mean that feelings do not derive from an underlying substrate of biological functioning which is
entirely deterministic.
