I think you've missed the point. It is not necessary that philosophical zombies exist, it is only necessary that the idea is coherent. The question then is, Could philosophical zombies exist? If you say no, then you are saying that consciousness is a necessary side-effect of the kind of intelligent behaviour that humans display. Do you believe that that is so, or do you believe that it is possible for a being to be made that behaves just like a human but lacks consciousness? You are free to dismiss this question as uninteresting to you but I think it is still a coherent question. -- Stathis Papaioannou -- You received this message because you are subscribed to the Google Groups "Everything List" group.
