As David said, this is arithmetical realism.
Yes, you can see a universe as the same thing as a model. When you have a (finite) set of rules, you will always get a universe from that set of rules, by just applying those rules an unlimited number of times. And the result of these rules is existing, in the same way as our universe is existing. Our universe is the result of some set of rules. The interesting thing is to discover the specific rules that span our universe. -- Torgny Tholerus --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
