   There is a name for the opposite belief -- that the behavior of the
universe can be understood.  It is called 'science.'  Understandably,
therefore, those of us who consider ourselves 'scientists' don't go
along with your opinion as expressed above.

   There is no evidence to support your statement (that the universe is
uncharacterizable), and there is substantial evidence to the contrary
(every successful prediction of science provides such evidence).

   I won't dissect this particular example, except to note that no one
has said that FTL travel is impossible.  What has been said is that
FTL travel is equivalent to time travel.  This is a logical necessity
(not an belief) under the single assumption that the laws of physics
are the same in all inertial reference frames -- an assumption which
is based on both experimental observation and philosophical elegance.

   Or it will never become a reality, and all it will mean is that you
were wrong.  Again.

   I can't help wondering how you can be so sure of yourself, in criti-
cizing others for being too sure of themselves.

Sometimes, David, you go overboard when you blast a posting like Bill's.  I
generally don't mind when you blast me, because I usually learn a lot in the
process.  But let's not let that process grind over poor old Bill without a
few words on his behalf.  "The universe is uncharacterizable in its
entirety" seems to me to be a true statement.  I can never know the state of
the universe because the memory required to hold that state would be bigger
than the universe itself.  Even when somebody does discover the GUT theory,
it won't characterize the universe in its entirety; we will use it to
characterize whichever small part of the universe we are looking at.

As for "...we are only Man, and when we characterize a thing, we
bring our own bias into the matter."  This is a restatment of the underlying
principle of quantum mechanics that says, when we do an experiment, our
observations change the results.

People should be criticized when they are *too* sure of themselves.  Perhaps
Bill's point was off the mark, but people who are *too* sure of themselves,
whether they be scientists, mystics, or whatever, probably are in a rut.

All too often people (and Rich Rosen) quote material from other people
and then comment on the quoted material in a way that does address what
was actually said.  Our example for today is:

Number 3 is quite blatant -- Gallmeister says "uncharacterizable in its
entirety by Man" and David renders it as "uncharacterizable".
Gallmeister asserts a certain type of limitation on knowledge and
David translates this into an assertion that no knowledge at all is
possible.

David's response in #2 is also unresponsive.  Gallmeister makes
the legitimate observation that our descriptions of the universe
are different in character from the universe itself, and David reads
him as saying that it is impossible to understand the universe.

I disagree.  There is no contradiction between the practice of science and
Gallmeister's statement; his statement isn't about the possibility of
scientific knowledge, but rather one of what that knowledge means.  If one
accepts the premise, then one can draw two conclusions:

1: That the universe must be trusted before the models, and

2: that a theory claiming that something is impossible must be read with all
   the implications about the permanence and structures of physical law kept
   in mind.

There is an argument about the possibility of communication with FTL
particles (Tachrons) which claims that it is impossible, because of TT
paradoxes.  The problem is that any such argument is based on a lot of
speculation about what time-travel really means.  More fundamentally, it is
based upon a whole network of notions about causality.  But if the universe
does in fact have tachrons going from place to place, then the new theory
need not honor those notions (although it must explain their apparent
macroscopic truth).

>>3. The universe is uncharacterizable in its entirety by Man, because

That merely shows that we can model some portion of the universe which we
experience.  I think the statement is a bit extreme, but it is a question
again of what scientific models mean.  I happen to believe that they for
almost all purposes satifactory as models.

   Ah!  This is a different interpretation of Gallmeister's statement,
which is in fact true.  We certainly cannot characterize the exact state
of the universe, even in theory; it simply is not possible to measure and
record the states variables of all of the different particles.
   However (although I don't have the context at hand) I don't think this
is what Gallmeister meant.  His meaning (I am paraphrasing a statement with
which I disagree, so be careful!) was that the exact characterization by
Man of natural law is impossible.  And this is that with which I disagree.
   Suppose we lived in a Newtonian world.  Suppose in fact that Newtonian
machanics were sufficient to predict exactly all physical occurrences (I
will leave aside the question of whether life, or intelligence, could
exist in such a universe).  Then we *would* be able to characterize the
universe, by those Newtonian laws.
   Similarly, I see no evidence that we do *not* live in a completely
characterizable world.  And I do see some evidence to indicate that we
*do* live in a characterizable world; the success of any partial char-
acterization is evidence (say, in the Bayesian sense -- I know PL doesn't
believe in such things, so he may diagree as to whether it constitutes
evidence) for characterizability, since it would be implied by character-
izability but would not be implied by noncharacterizability.  And I there-
fore feel justified in claiming that the question is not settled.  I do
*not* make the opposite claim, that the universe *is* characterizable;
if I were to do this I would be as guilty as Gallmeister of reaching
conclusions unsupported by evidence.  All I claim is that it *may* (or
may not) be characterizable; I prefer to *believe* that it *is* character-
izable, since I find that the assumption of noncharacterizability leaves
science essentially without foundation or justification.

   Exactly *my* point.  I am *not* sure of myself.  Gallmeister is the
one who made the positive assertion that the universe is uncharacterizable;
I only note that the question is at least open.

P.S. to Mr. Harter, and anyone else to whom my meaning is unclear.  When I
write "characterizable" or "uncharacterizable" without qualification in the
above, I mean "characterizable in its entirety by Man" or "uncharacterizable
in its entirety by Man" respectively.

P.P.S. The above P.S. applies to all future articles I write on this subject.

Please allow me to quote the Law of Fives:
        All phenomena are directly or indirectly related to the number
        five, and this relationship can always be demonstrated, given
        enough ingenuity on the part of the demonstrator.

This is the very model of what a true scientific law must always be: a
statement about how the human mind relates to the cosmos. We can never make
a statement about the cosmos itself--but only about how our senses (or our
instruments) detect it, and about how our codes and languages symbolize it.

We must remember that scientific inquiry can only build possible models to
describe the behavior we have observed. In this sense, we cannot understand
the universe, but only the models which we build. We can never make
predictions about what the universe will do; we can only make predictions
about our models. Sometimes these models accurately reflect what we observe,
sometimes they don't. Since these models are human artifacts, they must
_necessarily_ reflect our experience of human existance. They are not and
can never be complete representations of the universe!

This is not to say that the models we build are not useful! On the contrary,
they may be very useful, depending on their accuracy. But these models are
useful only in that they reflect our experience. The results of scientific
inquiry are not Truths of the universe. Rather, they are statements about
ourselves and how we perceive the universe.

Is it the opposite of science to say that there are things science cannot
find out?  I would hate to think I were anti-science -- I'd sure feel
stupid! I did not mean to say that science is a crock -- it works,
doesn't it?

I think it is obvious that the scientific method and the empirical quest
for knowledge have been, ah, successful, to understate things considerably.
At the same time, I think it is obvious that there are things science (as
we know it) can never discover, because this sort of knowledge is just not
susceptible to the empirical method of attack.

In short, I think that "Scientific Knowledge" is a proper subset of
"Knowledge".  I think it is a little pompous to say that you can learn
anything by the scientific method, and that, once science uncovers
something, it will never be disproven.

I'm not.  The emphatic wording of my posting was meant to stimulate some
