- "I guess I'm not sure what you mean by `correct'. Surely
- science isn't invalid because one believes a given theory can't cover
- the entire universe-- if so, all science up to the present day has
- been invalid. After all, we generally know that whatever constitutes
- current theory is merely a best approximation based on available data;
- violation of a scientific theory isn't a violation of universal law--
- it's merely evidence that there are cases current theory can't cover.
- Supernatural intervention might imply that there are cases that _no_
- theory _can_ cover, but there would still be a wide field of natural
- law which science would apply to. I don't see that makes science any
- less valid than post-Goedel mathematics is. If scientific validity
- depends on a belief that a Final Theory covering every phenomenon in
- the universe will be found, then I suspect that it's in danger
- regardless of the presence of a supernatural."

- "Statistical laws are, in part, a confession of ignorance. We
- can know position and momentum within precisely defined limits-- but
- further deponent sayeth not. Scientifically, a difference which is
- unknowable is no difference at all, and it's meaningless to say that
- a `real' precise position and momentum exists at all-- but the fact
- that something is unknowable doesn't necessarily mean that it's
- nonexistent-- and conversely, what we can't see we can't determine
- laws for.
-
- "It's the old canard about the tree falling in the forest; we
- presume that all the trees we don't see follow the same laws as all
- the trees we do see because that makes sense. Where we have _no_
- other trees to infer data from (as we have no data on position and
- momentum below the Heisenberg limits-- neither what they are, or
- whether there is such a thing) what goes on is a matter for idle
- speculation. What goes on in there, if anything, is not a matter of
- scientific law-- except that whatever it is can't contradict the
- observed statistical distributions. If, at an intersection, a third
- of the people turn right and two thirds turn left, this may be
- determined by the roll of a die, the aggregate free will of the
- drivers, or a traffic regulation. If all we have are counters in each
- direction, we can give the distribution, but we can't say anything
- about the cause-- it's a black box. Similarly, anything that goes on
- prior to the collapse of a wave function is a black box, and may
- conceal anything from nothing to self-willed electrons playing a joke
- on the universe."
