I know enough about the predictability of physical reactions to come to the realisation that physical reactions alone could not be entirely responsible for the unpredictable nature of many aspects of human behaviour.
It's very obvious from your posts that you don't, but ignoring that for the moment, how do you
know that the physical world can only do "reactions"?
The fact is that what you know is only about
current science, and that is obviously incomplete. If you could make your notion of free will make
logical sense, you couldn't possibly
know that it might not be some, as yet unknown, aspect of the physical world. If you could make your meaningless mantra about "the ever present state of conscious awareness" into a logically self-consistent proposition, you would have to claim to known
everything about the physical world to rule out a physical basis for it, not just what we have discovered to date.
As I said, you're confusing logical impossibility with the (unknown) limitations of the physical universe. If you really know that your version of freedom is impossible in the physical world, you must know that it's simply impossible, full stop.
