A variant of Chalmers' "Fading Qualia" argument (http://consc.net/papers/qualia.html) can be used to show Alice must be conscious.
Alice is sitting her exam, and a part of her brain stops working, let's say the part of her occipital cortex which enables visual perception of the exam paper. In that case, she would be unable to complete the exam due to blindness. But if the neurons in her occipital cortex are stimulated by random events such as cosmic rays so that they pass on signals to the rest of the brain as they would have normally, Alice won't know she's blind: she will believe she sees the exam paper, will be able to read it correctly, and will answer the questions just as she would have without any neurological or electronic problem. If Alice were replaced by a zombie, no-one else would notice, by definition; also, Alice herself wouldn't notice, since a zombie is incapable of noticing anything (it just behaves as if it does). But I don't see how it is possible that Alice could be *partly* zombified, behaving as if she has normal vision, believing she has normal vision, and having all the cognitive processes that go along with normal vision, while actually lacking any visual experiences at all. That isn't consistent with the definition of a philosophical zombie. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
