It's physicalism. First, he equates the mind with the brain. And while classical theology distinguishes between mind and brain, we do not, pace Descartes, identify the mind as the person.
It would also eliminate humanity before the brain has enough neurological connections to establish consciousness, an argument constantly used by pro-abortionists.That's not quite as bad as hard physicalism, but it is still unacceptable for Christians. For one thing, it eliminates life after death (since consciousness depends on the brain).
I agree with Jacob. But this also points out a major problem in this sort of thinking (although I loved the ethical questions they were raising) if science can only investigate things largely through senses and there things beyond our senses than of course science will rule that there is no reason to believe those. But those things are by definition beyond the senses so whoopty doo what science says.
