Subject: RE: Flood Model, batholiths, and science
Karen,
I have been trying to follow your interesting discussion with Steve as time
permits. I was reviewing the exchanges and saw something here that I wanted
to get your response to. You mention certain "unknown" factors that would
affect the ocean boiling/not boiling while certain heat processes were going
on. Are these natural factors? Or are they divine intervention? Since you
defend a YEC view (please forgive me if I misunderstand your position) why
are you trying to find natural factors to explain dinosaur deposits (they
way they are sorted etc). Given the model that you hold why not chalk it up
to God and have done?
My concern is twofold. If you are able to give explanations of the sorting
and deposits within a YEC flood model would that not result in this: we now
have a fully understandable cataclysm. A natural one to boot. Is that what
YEC wants? If we have a flood that is completely understandable in terms of
natural processes, would not have simple done nothing more than a paradgm
shift in science. How would that assert the reality of God's judgement on a
sinful world? And if you allow divine intervention to get you over the
gaps, how do you control that so that the appeal to divine intervention is
principled ? In other words, how does one allow the divine into a theory of
history (natural or otherwise) and still be assured that appealing to divine
action is not used simply to overcome theory weaknesses? I understand that
many defenders of ID or YEC say that this problem has an answer, but I have
yet to find it. Can you point me to what you think is a good response to
the problem.

True, I don't have the answers. But does lack of answers mean no science?
To me, it means research opportunities. The position I hold leads me to
suggest that calculations indicating that the oceans would boil away, etc.
are missing some major factors. At this point I don't know what those
factors are, but I am open to finding them. This is no more unscientific
(and possibly less unscientific) than paleontologists looking for missing
links, or astronomers looking for "dark matter". I have a different
paradigm of science, but that doesn't mean it is non-science.

Just one question regarding what is considered true science. I saw this
statement in a recent posting:
"Bottom line - it ain't science without the numbers"
What exactly is science defined as? As I understand the scientific method,
in order to establish something indisputably, it must be replicable. Where
does this leave much of the investigation into the distant past with issues
such as evolution/creation?
Don't get me wrong, I am not against examining the evidence we have now, but
I sometimes wonder 'just how much can we actually establish?' I hear people
assume evolution has been proven, and others saying it's been disproven: is
either statement valid? CAN either be?
I'm just looking for your reactions.

Numbers by themselves are not science. What matters is how they are used and
the conclusions drawn from them. Mathematics is more important in some sciences
than others.

Science is a very difficult thing to define. It is hard to get a definition
that pleases everybody because of the diversity of things we call science.
Trying to avoid amusing but unhelpful definitions like "science is what I do", I
have erected the following taxonomy.
There are several major complementary ways of knowing: aesthetic, theological,
philosophical, and scientific, for example. Within science I see five major
families: theoretical (mathematics), experimental (physics, chemistry),
observational (ecology, astronomy), historical (geology, archaeology), and human
(sociology, anthropology). These families are not exclusive, there are
overlaps, such as theoretical physics (theoretical and experimental), radar
astronomy (observational and experimental), and history (human and historical).
Much of the "scientific method" of each family is specific to it, but there are
some common themes. These include the fundamental assumptions that the universe
is both real and intelligible, recognition that speculation must be constrained
by observation (or mathematical proof) a commitment to reasoned investigation,
communication of results, methods, and interpretation to the scientific
community, and the verifiability of results.
Within my field of historical science, these principles work out as follows.
To do geology we must assume that the past is real and can be understood through
its material relics. Rocks are not ink blots into which we can read what we
will, but have particular characteristics which constrain our interpretation.
Our work must be rational and communicated to the geological community, and must
be in principle by verifiable by others. If we have done our work well other
geologists must be able to make the same observations and draw the same
conclusions.

I believe there is a hierarchy of "proof" in the historical science. For
example, there are many Tertiary limestones in southern Australia. A great deal
of work was done on them in the 50's and 60's. Their stratigraphy and lithology
was described and their fossil content and chemistry documented. They were
generally interpreted as being deposited at shelf depths in a large embayment
with little terrigenous sediment supply. Overall the environment was thought
to have been warm and tropical the Bahamas or Persian Gulf. These were the
main modern limestone environments generally known at that time. More recently
(in the last 15 years) geologists have recongised that limestones are also
deposited in cool water, such as the modern southern Australian continental
margin. The Tertiary limestones of the region reflect the characteristics of
these cool-water carbonates much more closely than they do those of tropical
regions. Thus the proof that water temperatures of southern Australia were
tropical has been disproved, based as it was on an inadequate model. Other
aspects of the model - shelf depths, deposition in an embayment, low sediment
supply etc., were not effected by this interpretation.
The situation is much the same with organic evolution. The fundamental basic
observation of evolution - common descent with modification, is well established
by a range of independent data. There are several plausible mechanisms,
including Darwinian evolution. The degree to which each of the mechanisms is
responsible for the pattern is a matter for exploration and discussion. Some
aspects, such as Proterozoic evolution are inherently difficult to determine,
because of limited data. Satisfactory models for biochemical complexity are
another problem. Such questions provide the agenda for future research. For
example, more than 3000 papers have been published on biochemical evolution
since 1965, compared with only 1000 before.

Science does not say that the actual events are replicable but that the
observations are replicable.

Science does not deal in absolute proof. But I would be interested in the
evidence that disproved evolution.

So would I in fact. I do think scientists, although not dealing with
absolutes, should be very careful in what they proclaim as truth. With the
issue of the list especially, there are many counterexamples to go with the
examples given by either side of these debates, and unless many or most of
these are accounted for I would say it shouldn't be called truth, possible
or probable maybe, but not truth. I understand how science points to the
past and what happened, but I also understand that we are quite fallible and
our interpretations may easily be off-base.
If you disagree, please speak up. I love being challenged in my beliefs!

Ernst Mayr might suggest that this is "physics"-centric view of science.
One can "do science" without numbers. That depends on the nature of the
question. Numbers and quantification can be nice to have, but they're not
everything. I'd say "it ain't science without the method".

Can we imagine no event or outcome which cannot be replicated and yet
can be established indisputably? I've performed experiments for which
the outcomes were difficult if not impossible to replicate. However,
I was able to determine the steps which lead to the result.

Everything happens in the past, at least by the time one notices.
What distinguishes the near past from the distant past? Perhaps
the quality of physical evidence. I suspect that the evidence
for common descent can be quite good at times.

See Ernst Mayr's "The Growth of Biological Thought", or Elliot Sober's
"Philosophy of Biology". And try working it out for yourself.
