Just because determinism is false with regards to reactions relevant to the brain and living things in general, doesn't imply that humans have a will. And even if you argue that humans have a will, it does not imply that the will is free.Well if you can take determinism off the table, then what is left? My thinking is very boolean on this. If we can show determinism to be false then therefore the opposite, freewill is true. Except if we have some other new thing that better explains it.
I'm also not to convinced by the quantum stuff yet. I think we're reading to much into it and it's still early days... (but that might just be me)
Sure, I think both are true and traditional arguments are there to support it. I am just saying you need some extra work to get there.
