 Consciousness and understanding are features of persons, so it appears that Searle accepts a metaphysics in which I, my conscious self, am identical with my brain – a form of mind-brain identity theory. This very concrete metaphysics is reflected in Searle’s original presentation of the CR argument, in which Strong AI was described by him as the claim that “the appropriately programmed computer really is a mind” (Searle 1980). This is an identity claim, and has odd consequences. If A and B are identical, any property of A is a property of B. Computers are physical objects. Some computers weigh 6 lbs and have stereo speakers. So the claim that Searle called Strong AI would entail that some minds weigh 6 lbs and have stereo speakers. However it seems to be clear that while humans may weigh 150 pounds; human minds do not weigh 150 pounds. This suggests that neither bodies nor machines can literally be minds. Such considerations support the view that minds are more abstract that brains, and if so that at least one version of the claim that Searle calls Strong AI, the version that says that computers literally are minds, is metaphysically untenable on the face of it, apart from any thought-experiments.
