One might also posit that if the sensation of free will that all humans experience as one of the must crucial truths of our existence is not represented in our current understanding of physical laws than the purely reductionist physicalist account of the universe is incomplete in a manner all humans validate. Not without great value and insight, just incomplete. This does make being a reductionist materialist untenable philosophically.and demands a more complete metaphysical model of reality that hopefully will allow for more meaning, transcendence and perhaps even the spiritual at some level.
