The Turing test would seem to imply that if it behaves like a bat, it has the mental states of a
bat, and maybe this is a good practical test, but I think we can keep computationalism/strong AI
and allow that it might have different mental states and still behave the same. A person given
an opiod drug still experiences pain, although less intensely, and would be easily able to fool the
Turing tester into believing that he is experiecing the same pain as in the undrugged state. By
extension, it is logically possible, though unlikely, that the subject may have no conscious experiences
at all. The usual argument against this is that by the same reasoning we cannot be sure that our
fellow humans are conscious. This is strictly true, but we have two reasons for assuming other
people are conscious: they behave like we do and their brains are similar to ours. I don't think
it would be unreasonable to wonder whether a digital computer that behaves like we do really
has the same mental states as a human, while still believing that it is theoretically possible that a
close enough analogue of a human brain would have the same mental states.
