But if there are potentially an infinity of laws, RW -- then how would that be logically any different than a state of perfect randomness -- putting it crudely, an infinity of laws would all be "vying with each other to express themselves" (so to speak)? On the other hand, if there were an infinity of universes, this might be possible -- but how would we be able to demonstrate the existence of an infinity of universes in the first place?
My intuition is that there has to be some practical limit to the number of laws that apply to a given universe in order for that universe to be "what it is" and not some other universe. I'm sure I'm stating the matter crudely -- does it make any sense?
BTW, I really liked your qualification: discovery or invention. Personally, I incline to the former view.
