One word: paragraphing.
Paragraphing is evidence of an organized mind.
As I've said before several times, we don't NEED proof of determinism since it's necessary to assume it. I just find it strange that while people assume determinism (that everything happens as the result of some thing or things preceding it) they then want to pretend it isn't there.
Of course there's interplay between the subconscious and conscious levels of the mind, because the subconscious can't possibly tell the consciousness level what to do without any basis at all. That basis is the world of sensory perception, which is the conscious world. But what are you asserting? that somehow there's no causality involvedl in this interplay? that this fact salvage free will in some way?
BTW, yet again, please define free will so that I can criticize that, if I can, or so that we at least understand what we are talking about. I maintain the entire notion is nonsense and your inability to define it satisfactory will be a major piece of evidence.
Many mental processes are automatic and involve no actual decision-making at all. They obviously HAVE to be beyond one's conscious control. Reflexes are just one example. Yet another nail in the coffin of free will.
