“Equally favorite: Philosopher John Searle’s proof that no digital computer can have mental states (a mental state is, for example, your state of mind when I say, “Picture a red rose” and you do)—that minds can’t be built out of software. A digital computer can do only trivial arithmetic and logical instructions. You can do them, too; you can execute any instruction that a computer can execute. You can also imagine yourself executing lots and lots of trivial instructions. Then ask yourself, “Can I picture a new mind emerging on the basis of my doing lots and lots and lots of trivial instructions?” No. Or imagine yourself sorting a deck of cards—sorting is the kind of thing digital computers do. Now imagine sorting a bigger and bigger and bigger deck. Can you see consciousness emerging at some point, when you sort a large enough batch? Nope.
“And the inevitable answer to the inevitable first objection: But neurons only do simple signal transmission—can you imagine consciousness emerging out of that? This is an irrelevant question. The fact that lots of neurons make a mind has no bearing on the question of whether lots of anything else make a mind. I can’t imagine being a neuron, but I can imagine executing machine instructions. No mind emerges, no matter how many of those instructions I carry out.”
