the neuroscientists who have investigated free will, Libet, Gazzaniga, seem to support the idea that we don't have free will, we're like machines responding to signals that have established their patterns in our brains, habit creates most of our responses, and indeed we live so much of our waking life in auto-pilot, relying on these patterns that are all but conscious and that run all the times. it's unsettling maybe but this knowledge can even make us better, if so much of what we choose is already dictated by previous actions, then we can really decide to change, by breaking our habits, learning to choose better, choose differently, we exercise free will... but if free will didn't aim at this betterment, what would be its use?
