Hey Benny... suppose that science is limited to the physical, and that mind involves something beyond what science is currently equipped to wrap its hands around... I think this is an entirely reasonable suggestion... could you not come to the proposition of property dualism without embracing idealism? If so, why not simply stop there, without appealing to the more radical claim, i.e. mind precedes matter?
