I was struck by the similarity between such Dualist campaign to downgrade physical views of human beings and the story of aliens who snatched the bodies of human victims and replaced them with strange facsimiles. Of course, it may not appear that dualists and spiritualists are out to snatch away one’s body and replace it with an alien likeness….But they do seem intent on reducing the human body-brain to mere matter-in-motion, a primitive form of material existence that cannot support the complex and high level of activity that we justifiably credit to our corporeal nature.
