That is an interesting point: you need an external reality against which the simulation can be measured in order to be able to say that it is a faithful simulation. So, if I had to choose a brain replacement I would choose one that had objectively been shown to be functionally equivalent to the original. An example of such an objective test would be previous recipients who claim to feel the same as before and whose family and friends is unable to notice any significant change in behaviour. Of course, it is possible that I could be perfectly happy with an imperfect brain replacement, where others notice a change in my behaviour but I don't myself, but pushing this too far leads to absurdity: I might be happy if a wicked witch turned me into a toad, since as a toad I wouldn't remember or miss being human. If there is no objective external world but it's all part of the simulation then you're right, there's no sense in saying the sky looks different but I'm fooled into thinking it looks the same, unless this is relative to other conscious beings in the same simulated world. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
