[!QUOTE] One of the things one starts talking about is this notion of what we call rulial space, which is the space of kind of possible different views of how the universe works. So we might say we’ve got one view of the universe, “Oh, it works this way, it follows this rule.” And then some other person, alien, whatever, says, “No, no, no, you’re quite wrong. The universe really works according to this other rule instead.”
