Electronic aids, particularly domestic computers, will help the inner migration, the opting out of reality. Reality is no longer going to be the stuff out there, but the stuff inside your head. It's going to be commercial and nasty at the same time, like 'Rite of Spring' in Disney's Fantasia ... our internal devils may destroy and renew us through the technological overload we've invoked.

Wheeler hopes that we can discover, within the context of physics, a principle that will enable the universe to come into existence 'of its own accord'. In his search for such a theory, he remarks: 'No guiding principle would seem more powerful than the requirement that it should provide the universe with a way to come into being.'. Wheeler likened this 'self-causing' universe to a self-excited circuit in electronics.
