I present an (older) argument that if we take the hypothesis that "we" are (turing) emulable, then we can doubt that there is a "physical level" at all. Put in another way, the appearance of a physical level could be a higher-order cognitive phenomenon, not specifically human, but "universal machinian", if I can say. Physical laws could emerge from some gluing property of machine's possible histories. In fine, the laws of physics would come from statistical relation on numbers relations. On this list many people agrees that computation and relative probabilities play some role. Some other insist on states with some absolute probabilities or universal prior (cf Hal Finney). I think Tegmark and Schmidhuber obliterates a bit too much the mind- body question. I am already happy when I can help people to understand that the mind-body problem is a difficult but serious problem and that, by assuming hypotheses of the type of comp, we can try reasoning and been led to startling and very counterintuitive (for an Aristotelian) conception of "reality", and we can even do math. Don't hesitate to ask, perhaps more specific, questions. But if *you* don't care on consciousness or mind, I'm afraid you could be bored quickly. The recent posts try to single out the falsity (or the difficulties) of the identity thesis( linking "consciousness" and "physical state of a brain") when computationalism is assumed.
