I used to be a physicalist. For those that do not know, physicalists believe that there is no immaterial aspect to man. I also was incredibly put off by the Cartesian Dualism that it seems many Christians hold to. I heard of an alternative... Substantival Monism as held to by Greg Bahnsen. I read his article on it but am still confused on what it is and how it differs from Dualism. Anyone care to explain?
