Incorrect - scientific models can never be tested against reality.
They can only be tested with what we can perceive.
It is true that models may not represent the reality exactly, but a
model that has been employed not only in its original context but is
many others and which still works can be expected to represent reality
very well, even if not exactly.
This is the basic problem of knowledge - what can we say is likely to be
right? We are most warranted in thinking that models that continue to
work and work aidely are true. There is always a margin of error, but
that's the nature of real knowledge.
Knowledge that is certain, and which has no error, is not existent.
Nobody hs that sort of knowledge.

Of course it might be wrong - that's the nature of science.
But to suggest that because evolutionary theory may be wrong some
other "theory", such as one of the many esposed by creationists, can
be correct is downright silly. Those other "theories" were falsified
centuries ago. In science a falsified theory does not make a comeback,
and those who persist in supporting falsified theories lose any
credibilty.

Except, of course, the knowledge that no knowledge is certain.
Seriously, though, it is a mistake to set up an impossible ideal for
knowledge, and then complain that knowledge doesn't come up
to that ideal. The fact that nothing comes up to an impossible
ideal does not show a fault in those things, but a fault in the
ideal.

But this is the important point. Do you agree with it? In the past,
scientific theories have been replaced by other scientific theories.
Are there any cases of scientific explanations being replaced (due to
evidence) with an older supernatural explanation?

If not, perhaps you can give an example of a completely and utterly

I'm sure that you will also agree that scientific theory is based on
the interpretation of the evidence as objectively as possible, and
that personal conviction carries no weight in science no matter how
strongly that personal conviction is held.

Correct! The fact that new scientific theories and models have
replaced
old ones did not mean the old ones did not work - it means the
theories
and models have some limitations. The new theories and models
that work are still not the reality but a product of our human
imagination
and innovation.
Humans have developed many strategies for gaining or generating
knowledge.
I have not come across anyone who claim the framework is ideal.

Scientific models used to be influenced by religious beliefs.
The efficacy of the model only depends on whether it can be validated
and useful.
Yet one cannot deny that the model is not reality itself.
Of course one can deny that. If we can't know what 'reality' is, then
we can't know that our model isn't a proper representation.
Models are not required to describe 'reality'; they are, as you say,
useful, and they are useful only in so far as they aid in formulating
theories and making predictions. (Models are not theories, I hope you
realize that).

If a model is _wrong_, it is probably useless, except perhaps for
disproving a hypothesis.
Most scientific models are, perforce, incomplete. If they modeled
reality completely, they would *be* reality. If you think that is the
purpose of a model, you are mistaken on some very important aspects of
modeling.
It is desirable that a model be as simple as possible, and still
perform its intended function. Once a model becomes overly complex, it
gets unwieldy, and that's when errors start creeping in, and it can be
tough to find and correct them, since you've made the model badly.
Simple systems call for simple models. You can model a system of a
single gene with two alleles, with, say, a given selection pressure,
with a simple BASIC program. Hell, you can do it with pencil and
paper, and it would probably be faster than writing the program (and
you wouldn't need to wash up afterwards, like you do after programming
in BASIC).
But if you want to model the effect of a strong El Nino event on the
economics of subsaharan Africa, you'd better have a team of savvy
computer jockeys handy.
And in fact, models aren't really "right" or "wrong". They're accurate
to varying degrees. A poll is a model. Did you ever notice that polls
always have about the same number of respondents? About 1200, I think.
Ever wonder why? Because that number gives just about a +/- 2.5% -
3.0% error margin, or just about 95% confidence. They don't go further
because they hit diminishing returns after that- it's just not worth
it economically to have 99% confidence in the poll. The same is true
of biological models, although the cost is measured in time and
effort, rather than money. Remember, perfection is the worst enemy of
getting a job done on time (or something like that).
Chris

The problem you have if you want to push religious conviction into

So what? It works. I don't care if it is any ultimate reality or not.
It doesn't affect the nature of science or the validity of its
findings.
If you want to claim some superior reality based on your personal
convictions, fine. Just don't call it science.
And by the way: if you want others to change their beliefs so that
they line up with yours - i.e. by wanting to call your beliefs
"science" and have them taught as science in science classroom - then
you need to offer rather more than the strength of your personal
conviction in support of your argument. The world is filled with
people whose convictions are different from yours. Many are
diametrically opposed to yours. Unless you can provide some objective
way of judging the validity of all those personal convictions, why
should anyone accept yours rather than anyone else's?

This may be true, but it is irrelevent.

Science is, and can only be, about what we perceive. If reality is
different than that in some way that we may not perceive, we can't discover
that.
Of course, it is hard to see how reality matters in that case either.
Mark
Neither are the maps we create 100 % accurate representation of the land area they represent,
thus they do not represent reality.
Scientific models are like maps.
I guess that in your opinion they are therefore useless and should be replaced by beliefs like
"Here lie dragons"?

The idea of an "absolute reality" is an philosophical concept which
has little relevance to science. All theories in all branches of all

that science can every reach any absolute reality.

How do we know what 'actually' happens in nature?
-tg
All any of us can do is produce models of reality. What you see
through your eyes is not, in fact, what you see through the physical
optical hardware in your eyes, but rather a model produced by the
brain.
That is precisely why the scientific method was developed, to produce
a means by which theories can independently tested and observations
independently confirmed.
Now, unless you're an advocate that the entire human race is somehow
under a singular delusion whereby multiple and independent confirmations
are in fact merely the product of mass hallucination, that suggests
that reality *is* modellable, that one *can* create theories to
explain and predict physical reality, and that those theories *can*
be tested to determine whether or not they accurately explain some
aspect of physical reality.
Your post above suggests very heavily that, when cornered on this,
you are going to advance a nihilistic explanation. This is hinted at
pretty strongly by other threads you have created where you attempt
to put forward a claim that because there are multiple explanations
for a given phenomona, that that undermines any (or perhaps all)
theories as being reasonable and useful means of explaining nature.
It's my opinion that you are trying to put your own religious
beliefs (and no doubt the pseudo-science informed by those beliefs)
on an equal footing with certain scientific theories that don't
jive with your specific beliefs. You seem quite keen to avoid
openly declaring this, rather trying to work from a strategy of
creating some framework in which you can insert your as-yet-unrevealed
beliefs, with the idea that you have seriously called into question
the ability of scientists to produce reasonably accurate and useful
explanations.
I'm just trying to cut this whole silly strategy off at the pass because
I personally find it tiring to have to wait for weeks, wading through
dozens of posts, each one apparently designed as one cut in a
death of a thousand cuts strategy, only to find out that what we have
has is a stock Creationist claim.
This seems to be a new strategy. Someone2, who is putting forth a
dualistic claim about human consciousness (well, if he ever gets around
to it) is using a similar set of tactics. Perhaps your ministry has
suggested this to you as a means to show all those evil atheistic
evolutionists up. I dunno. Maybe it's just coincidence, but in either
case I find it a rather dull and silly way to debate.
If you don't believe that we can produce theories that explain the
physical universe, or you believe certain aspects of the universe
are exempt from scientific probing, then just come out and say it.
It's not like we don't know what you're trying to do, so this whole
tactic seems pointless.

Yes, when interference phenomenon of light was discovered, it
certainly
undermined Newton's Corpuscular theory of light. But it was good
news
rather than bad news. Recognizing that models are not realities
enabled
science to progress. In the case of the theory of light, it
progressed to
Huyghen's Wave Theory., then to the Particle-Wave Duality Theory,
This does not undermine science.
On the contrary, we learn through our humility.

You should be thinking about where you'd like to move that goalpost:

Nonsense.
It's evidence which leads to the development of a more robust model.
Personal conviction of the validity of a model may lead a scientist to
further testing, but so can the conviction that the model is false.
The scientist may have no conviction one way or another. What matters
is how well the model or theory stands up to testing against the
evidence.
> The issue is not the validity of the scientist's personal convictions
but rather the model's validity.
The validity of the model is built on the evidence. The personal
convictions of the scientist don't enter into it.

It's tested against the evidence, and reflects a portion of what you
may want to call "absolute reality". It represents real phenomena.
It's not just a bit of fantasy, or a game with words and numbers.

about what scientists do and how science works which is simply wrong?

Man has developed tools throughout his history to extend what he
perceives. Just because man is limited in his understanding does not
mean there are no forces acting on him and his environment effecting
his universe.
Radio waves come to mind, they are impacted by sun spots as is the
weather. The sunspots existed long before we could directly detect
them or even speculate about their existence.
I suspect there is still much about our universe to which we are
still blind. We keep on learning about what has always been there.
How brief a period of man's scientific quest has the sub atomic been
known.
The ostrich still should pull his head out of the sand, if possible.

I think we all overlook many special facets of man when we don't
personally develop a special talent. Not everyone can think in
formulas or create music or art. Not everyone can dig a ditch day in
and day out.
All music, art or mathematical equation or theory is beautiful to
someone else. I recently read the history of the ideation leading to
discovering "Black Holes." One scientist in Russia wrote about his
hypothesis supported by his calculations. An American scientist was
taken by the notion, but did not try to disprove the Russian's proof,
he took the idea then prepared his own proof. The conclusions were
the same thus persuading the American scientist that the Russian might
have arrived at a useful conclusion.
Men lived quite well thinking the sun circled the earth. That didn't
mean it was true.
Ideas are ideas. Nothing special about the category. Have you
noticed how many scientist are musicians? If you insist on a narrow
discussion you will miss the true nature of man's consciousness.

Sounds like a 'wild card' response. Why drag in religion
specifically? Religions are just another category of models and
theories, right?

Science has restricted itself to a small part of man's experience. I
have no problem with the restrictions, but when it becomes an excuse
to ignore other models about existence, I cringe. Science cannot
determine who will be the "best" next President, it may be able to
predict who the next President will be.

You may well be seeing truth I don't see. Are you sure it is not your
agenda being pasted onto the original statement?
The psychiatrist finished displaying the deck of ambiguous pictures.
He observed to his client, "you seem to think about sex a lot." The
patient responded, "you're the one showing me dirty pictures!"
