| > Do you believe that a robot cannot have qualia? We're getting stuck on semantics here. I do, but then I'd cease to see it as a robot, and more a sentient being. One criterion of consciousness that I've encountered is, 'there is something what it is like to be <x>' (Thomas Nagel). If there's something 'what it is like to be' a robot, a bat, a mosquito, an ameoba, a rock... then it is conscious. > I believe that the question of "what is pain" and the question of "is pain a good criterion for deciding whether it is acceptable to do harm to something" are two totally different philosophical problems. They are connected only insofar as we have chosen pain as a proxy for harm. But that very relationship between pain and harm indicates that pain is not just some kind of soulful feeling, but rather a signal to help us evade harm now or in the future. Qualia is more broad than just pain, of course. I just picked this particular phenomenon for it's poignance :) If it is conscious, ethically speaking, we should consider how we treat it in a manner different to something that isn't. So if a rock isn't conscious, and some interconnected neural/silicon device is, we should at least have some way to query whether it is in an undesirable state or not.. if feasible/practical. Maybe if trees/plants/rocks/ameobas are conscious, we can't be consulting their feelings when we harvest crops, or use disinfectant, mine for precious metals etc. We can make decisions to treat livestock better, and change how we utilize our environmental resources - so we ought to, and we are. But if we were to go out of our way to make new conscious entities, don't you think we should extend our historical shifts in attitude to slavery and our growing shifts in attitude to animal welfare also to these new entities? |
