Why do you say there are very few? Again, it seems to me that for any "honest" universe, there would be an infinite number of "deceptive" universes that mimic it's appearance. Unless you have some reason to exclude universes like I described in my response to Brent. > However in a universe with evolution, the > initial condition can be a more or less random arrangement of particles, for > which there are far more possibilities. FIRST: Evolution doesn't add anything. It's all in the initial conditions and causal laws. In a determinisitic universe, things can only happen one way. Evolution is just a label that we put on the way that they appear to have happened in our universe. Evolution is a description, not an explanation. SECOND: Your statement is only true if our causal laws are such that any random starting conditions lead to conscious life. But there all that you've done is moved the "specialness" from the initial conditions to the causal laws. You are claiming that our universe has a "special" set of causal laws that can start with nearly any random arrangement of matter and end up with conscious life that will be able to perceive true things about their universe. A good analogy would be the quicksort algorithm, which can start with any randomly arranged list and always produce a sorted list from it. BUT, the quicksort algorithm is special. If you just randomly generate programs and try to run them, the probability of getting one that will correctly sort any unordered list must be very low compared to the probability of getting a program that won't do anything useful at all, or sorts the list incorrectly, or sorts it very inefficiently. Equivalently, if you just randomly chose sets of causal laws, the probability of selecting a set of laws that can start from almost any random arrangement of matter and from that always produce conscious life that perceives true things about the laws that gave rise to it must also be very low.
