- I rarely disagree with John Baez. But I think there is an important
- question here.
-
- To say that a certain object exists is like saying that it's in the
- universe. There isn't anything wrong with that. But then, to say
- that the @i[universe] exists is saying that the universe is inside
- itself - which makes no sense at all. And the trouble is that the
- ordinary way of saying things like "X exists" is a useful shortcut
- that causes trouble when you try to think more about it, because what
- we really should say is not a simple predicate E(x) at all, but a
- relation IN(x, U) -- that is, we should say X is in Universe U.
- To see why this is serious, imagine the predicament of a person
- like Tron (or you, or me) that is actually being simulated by a
- Virtual Reality Program inside some computer C. I'm not joking.
- Clearly, you couldn't tell whether you were absolutely "real" or
- 'just' a program inside some computer C. Because there's no way to
- detect C itself.
- "OK," you might object. "But that is a real program running in a
- real computer. So it does -- sort of -- exist."
- Yes, but now consider the program just sitting there as some
- writing on paper. Not running in a computer at all. But simulating
- the processes that you and I embody. Then those process still have a
- sort of potential performance, because the instructions specify what
- happens from each step to the next. A lower grade of existence,
- perhaps, but we should still ask to what extent such an abstract
- process can feel or think or have "experience"?
- And so far as I can see, the internal experience ought to be
- exactly the same. To the abstract process, each abstract pleasure,
- satisfaction, or frustration or pain should be the same -- and
- precisely as real -- to that abstract process, as is a real
- satisfaction or frustration to a real process. And we can make the
- same statements about each of these "grades of existence":
- --P runs inside some actual computer
- --P runs only in the mind of its human programmer..
- --P doesn't run at all, but just sits there on paper.
- --P isn't even written, but only imagined by someone.
- --P isn't even imagined, but merely a "possible" program, not yet even
- conceived by anyone.
-
- In each such case, if P describes some simulated universe, there
- is no way for the creatures inside that universe to know whether or
- not their universe "actually exists" as a feature inside some larger
- universe. No answer to such a question could have any actual
- consequences -- and therefore, the attribute of existence is an
- inconsequential accessory! There is no possible way to prove that our
- universe itself is anything more than a "logical possibility". So all
- that religious garbage about "who created ..." is based on a simple
- mistake, of postulating an unnecessary entity. (There is a nice
- complaint about this in Einstein's "Meaning of Relativity" book.) It
- reaches it's most ultimately stupid form in terms like, "God created
- God, of course. Who else could have done it."
