The dreamer is not functionally identical to the rock because he is dreaming and the rock isn't (I'll avoid starting up another rocks are conscious discussion). If the dreamer could talk, he would tell you that something is going on, while the rock would not. It isn't really fair to say that the outputs are the same simply because the lines of communication are down, or because eg. you are deliberately trying to fool the external observer into thinking everything is the same. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
