Most Christians (unless you teach at Fuller) will hold some sort of mind/body dualism. That is, the mind is not a physical object. If this is so, can one speak of the mind using physical-causal language? Is it right to think of the relations of ideas as one thinks of the relations of two objects interacting causally? Does a non-materialist view of the mind eliminate objections to free will (i.e., classical combatibalism expressed in similar ways by Christians such as Augustine, Calvin, and Edwards)?
