How do I go about obtaining a probability distribution over all possible universes conditioned on nothing?
I don’t need to. I just need to show that if we do get such a distribution (over possible universes, or over some such subset), then SIA update these probabilities. If we can talk, in anyway, about the relative likelyhood of universe Y versus J, then SIA has a role to play.
