A few
years ago it was "Creation Science" they
were trying to teach in the schools.
Creation
Science was an attempt by fundamentalist Christians
to give the Genesis account, as interpreted by them,
a scientific veneer.
But it
was only that a thin surface and any student
who actually believed that Creation Science had
anything to do with science would have been educationally
crippled.
Now the
controversy is between advocates of the theory of
Intelligent Design vs. strict Darwinists.
And some people want you to think it's the same
argument.
It
isn't.
What
Is "Intelligent Design"?
My first
exposure to Intelligent Design theory was Michael
Behe's book Darwin's Black Box: The Biochemical
Challenge to Evolution. While disavowing
any Creationist agenda per se, Behe pointed out
serious problems in the strict Darwinian model of
evolution.
Basically,
Behe's approach was this: Complex systems in advanced
organisms depend on many biochemical steps, all
of which must be in place for the system to work
at all.
So how,
Behe asked, could such a complex system have evolved,
if the only method available was random variation
plus natural selection?
It would
be impossible to believe that the entire series
of steps in the complex system could randomly appear
all at once. But any one step along the way,
since it does nothing by itself, could not give
the organism that had it any competitive advantage.
So why would each of those traits persist and prevail
long enough for the complex system to fall into
place?
Behe's
conclusion is that since complex biochemical systems
in advanced organisms could not have evolved through
strict Darwinian evolution, the only possible explanation
is that the system was designed and put into place
deliberately.
In other
words, though he shuns the word, complex systems
had to have a creator they have to be intelligently
designed.
The Darwinists Reply
The Darwinist
answer was immediate. Unfortunately, it was
also illogical, personal, and unscientific.
The main points are:
1. Intelligent
Design is just Creation Science in a new suit (name-calling).
2. Don't
listen to these guys, they're not real scientists
(credentialism).
3. If
you actually understood science as we do, you'd
realize that these guys are wrong and we're right;
but you don't, so you have to trust us (expertism).
4. They
got some details of those complex systems wrong,
so they must be wrong about everything (sniping).
5. The
first amendment requires the separation of church
and state (politics).
6. We
can't possibly find a fossil record of every step
along the way in evolution, but evolution has already
been so well-demonstrated it is absurd to challenge
it in the details (prestidigitation).
7. Even
if there are problems with the Darwinian model,
there's no justification for postulating an "intelligent
designer" (true).
Let's
take these points in turn:
1. You
have to be ignorant of either Creation Science or
Intelligent Design or both to think that they're
the same thing. Creation Science is embarrassing
and laughable its authors either don't understand
science or are deliberately deceiving readers who
don't understand it. Frankly, Creation Science
is, in my opinion, a pack of pious lies.
But the
problems that the Designists raise with the Darwinian
model are, in fact, problems. They do
understand the real science, and the Darwinian model
is, in fact, inadequate to explain how complex systems,
which fail without all elements in place, could
arise through random mutation and natural selection.
If Darwinists
persist in trying to tar the Designists with the
Creation-Science brush, then it is bound to appear,
to anyone who has actually examined both, that the
Darwinists are trying to deceive us. (They're
apparently counting on most people to not care enough
to discover the difference.)
2. Real
science never has to resort to credentialism.
If someone with no credentials at all raises a legitimate
question, it is not an answer to point out how uneducated
or unqualified the questioner is. In fact,
it is pretty much an admission that you don't have
an answer, so you want the questioner to go away.
3. Expertism
is the "trust us, you poor fools" defense.
Essentially, the Darwinists tell the general public
that we're too dumb to understand the subtleties
of biochemistry, so it's not even worth trying to
explain to us why the Designists are wrong.
"We're the experts, you're not, so we're right
by definition."
Behe and
his group don't think we're stupid. They actually
make the effort to explain the science accurately
and clearly in terms that the lay audience can understand.
So who is going to win this argument? Some
people bow down before experts; most of us resent
the experts who expect us to bow.
The irony
is that there are plenty of Darwinists who are perfectly
good writers, capable of explaining the science
to us well enough to show us the flaws in the Designists'
arguments. The fact that they refuse even
to try to explain is, again, a confession that they
don't have an answer.
4. When
Darwinists do seem to explain, it's only to point
out some error or omission in the Designists' explanation
of a biochemical system. Some left-out step,
or some point where they got the chemistry wrong.
They think if they can shoot down one or two minor
points, then the whole problem will go away.
They ignore
several facts:
The Designists
are explaining things to a lay audience, and Behe,
at least, tells us up front that he's leaving out
a lot of steps but those steps only make the system
more complex, not less.
The Designists
are working from secondary sources, so they are
naturally several years behind. Of course
a scientist who is current in the field will understand
the processes better, and can easily dismiss the
Designists as using old, outmoded models of how
the systems work.
What they
never seem to show is how the new understanding
reveals a system that is not complex after all,
one in which each step in the process confers independent
benefits on the organism and therefore could have
evolved through random mutation and natural selection
alone.
They don't
do this because the current findings rarely reveal
a simpler process than was previously thought.
Almost invariably, they find that the system is
more complex and therefore harder to explain, and
therefore the Designists have even more of a point
than they thought.
5. The
church and state argument is deliberately misleading.
First, the Designists are not, in fact, advocating
"God." They are very careful not
to specify who or what the Intelligent Designer
might be. So they are not advocating for any
particular religion, or any religion at all.
For all anyone knows, the supposed Intelligent Designers
might be an alien species of mortal, ungodlike beings.
To the
Darwinists, of course, this is hypocrisy and deception
of course the Designists are religious.
They must be. Because only religious people
would ever question the Darwinist model.
It comes
to this: If you question the Darwinist model, you
must be religious; therefore your side of the argument
is not admissible in the public arena, and certainly
not in the public schools.
This is an attempt to shut down discussion by hiding
behind the Constitution. It's what you do
when you're pretty sure you can't win on the merits.
6. The
"we can't possibly find every step along the
way" argument is an old one that doesn't actually
fit the current situation. It is the correct
answer when defending the idea of evolution against
those who believe in an ex nihilo creation in six
days.
The fossil
record is very clear in showing the divergence of
species, with old ones going extinct and new ones
arising over a long period of time. And the
general progression is from simpler to more-complex
organisms. The fact that evolution takes place
is obvious. You don't have to find some improbable
fossil graveyard where each generation conveniently
lay down next to their parents' bodies when it came
time to die.
But fossils
only show physical structures, and the Intelligent
Design argument concedes the point. The Designists
(or at least the smart ones) are not arguing for
biblical literalism. They freely admit that
evolution obviously takes place, that simple organisms
were followed by more complex ones.
They also
accept the other obvious arguments for evolution,
like the similarity of genes among different species.
They have no problem with the idea that chimps are
so genetically similar to us because we share a
common ancestor.
Their
argument isn't against evolution per se. Nor
are they doubting that natural selection takes place.
Their argument is that the Darwinian model is not
a sufficient explanation.
So "we
can't find fossils representing every step of evolution"
has nothing to do with the issues being raised.
The Designists are not anti-evolution. They
are anti-Darwin.
Darwinism vs. Evolution
Here's
the place where a lot of scientists indulge in muddy
thinking. Evolution and Darwinism have been
treated as synonyms for so long that too many people
think they're the same thing. But they're
not, and never have been.
Darwin
did not think up the idea of evolution any more
than Columbus proved to a bunch of flat-earthers
that the world was round.
In fact,
the Columbus analogy is an apt one. Columbus
was actually wrong he was arguing, not that the
Earth was round (everybody knew that already) but
that the Earth was much smaller than it really is.
His claim was that the Earth was so small that if
you sailed west from Spain, you'd find Japan at
about the point where in fact you find Cuba.
He was
vastly, ridiculously wrong but because his expedition
got funded, he was able to sail west far enough
to bump into a largely unknown (to Europe) land
mass, and the civilizations that dwelt on it.
Whereas
the sensible people who knew how big the Earth was
refused to endanger themselves by sailing west on
a voyage so long that no ship could carry enough
supplies. And therefore discovered nothing.
Darwin's
contribution to biological science is enormous.
He posited a means by which science could study
the passage of organisms from one species to another
over time. Before Darwin (and the others who
were working in the same direction), there were
many who believed in evolution, but accounted it
part of the "great chain of being" ordained
by God.
Here's
the thing: If you say that things are as they are
because God made them that way, then they are off
limits to science. Science is simply unsuited
to studying God. Science requires impersonal,
repeatable testing. Its business is discovering
causal relationships, and it can only work with
mechanical cause.
So when
the answer to the question "why does this natural
phenomenon occur?" is "because God wants
it that way," then science simply has nothing
to add to the conversation. Any more than
when the question is "why are you wearing that
combination of colors?" If some person
divine or otherwise chose to make things as
they are, then we're talking about purpose and motive;
science can only work with mechanical causation.
In other
words, until Darwin showed us evolution as a machine
that did not require divine meddling to be explained,
scientists were blocked from answering what seemed
to be (and, in some ways, is) a mere historical,
not scientific, question: How did this vast variety
of life forms come to be?
The
Scientific Method
Of course
scientists can't document every step of the historical
process of evolution. That wouldn't be science
anyway; it would be mere data collection.
What science
does is to invent plausible stories of automatic
processes by which natural events, systems, and
objects come to be as we see them.
Then the
story is tested, either by experiments designed
to prove the story false, or by making predictions
about what else must exist if the story is true,
and then seeing if the predictions are right.
Science
examines ongoing processes that proceed from mechanical
causes; Darwin, by convincingly describing evolution
as such a process, opened the door to millions of
insights into the workings of organisms of every
size.
Make no
mistake: Not just the fossil record, but virtually
every close examination of biology at every level
reveals utterly convincing evidence that evolution
takes place, has always taken place, and continues
to take place. There is also plenty of evidence
that natural selection takes place.
The Designists
challenge only the sufficiency of Darwin's model.
The claim only that it does not seem adequate to
explain systems that were completely unknown at
the time he created his theory.
Insufficiencies
Darwin
himself knew that there were sticky places where
his theory wasn't a sufficient explanation.
He wrestled with the problem of altruism, for instance,
and while he found adequate natural-selection explanations
for some forms of altruism (for instance, the mother
bird that draws off predators, potentially sacrificing
her life, to promote the survival of her offspring),
there were other behaviors that were inexplicable
by means of natural selection (for instance, humans
who voluntarily go to war to protect strangers).
There
are other problems with Darwin's model. For
instance, the idea of gradual change at a consistent
rate is challenged in some respects by the fossil
record. Some organisms have persisted virtually
unchanged for millions of years, only to suddenly
disappear; others have seemed to spring up suddenly,
with few or seemingly no precursors.
The result
was a modification in doctrinaire Darwinism, called
the "punctuational model," which proposed
that evolution can happen in bursts that are much
more rapid than the normal pace. It is not
really so much a contradiction of Darwinism as an
elaboration of it, a revision to help it fit observed
reality better.
Why
Theories Get Revised
It is
vital to keep in mind that Darwin's theory is a
theory, not in the way that Creationists mean (i.e.,
a theory and therefore not a fact), but in the way
that scientists use the word "theory":
a story that accounts for all the data that we've
found so far.
But good
science always examines its theories and compares
them to the evidence, to see if they are still adequate.
That's how Newton's "laws" (i.e., theoretical
constants) were able to be superseded by Einstein's
not because they weren't true, but because they
couldn't adequately explain all the phenomena that
were being observed.
I specify
"good science" because if, at any point,
any theory becomes a dogma that no one is allowed
to question, it stops being good science.
Indeed, it stops being science at all, and becomes
its opposite its enemy.
Darwin
himself was a scientist, and a great one, in part
because he was constantly probing and questioning
his own ideas.
But an
astonishing number of his defenders today are, at
least when discussing Darwinism, not scientists
at all.
They instead
behave like religious fanatics whose favorite dogmas
are being challenged. That's why they answer
their serious critics with name-calling, credentialism,
expertism, sniping, politics, and misdirection,
answering questions that have not been asked, using
answers that have nothing to do with the real questions.
They have
no good answers, and yet they have an unshakable
faith in Darwinism; so they fervently and vehemently
attack their attackers, waging, not one side in
a scientific conversation, but a crusade against
those who do not treat their Prophet with enough
respect.
More respect,
in fact, than Darwin would have wanted or ever showed
for his own ideas. Darwin had no problem with
questioning Darwinism. He constantly entertained
the possibility that he was wrong about this, that,
or everything. Would that his disciples today
would adopt the same attitude.
Here's
the only correct answer to the Designists:
7. Yes,
there are problems with the Darwinian model.
But those problems are questions. "Intelligent
design" is an answer, and you have no evidence
at all for that.
A Religious
Squabble
Intelligent
design uses the evil "must" word: Well,
if random mutation plus natural selection can't
account for the existence of this complex system,
then it must have been brought into existence by
some intelligent designer
Why?
Why must that be the only alternative?
Just because
the Darwinian model seems to be inadequate at the
molecular level does not imply in any way that the
only other explanation is purposive causation.
There
might be several or even many other hypotheses.
To believe in Intelligent Design is still a leap
of faith.
But the
normal answer of the Darwinists is also a leap of
faith. In effect, their arguments boil down
to this: We have no idea right now how these complex
systems came to be, but we have fervent, absolute
faith that when we do figure it out, it will be
found to have a completely mechanical, natural cause
that requires no "intelligent designer"
at all.
If the
Darwinists' faith is eventually proved correct,
and we find completely natural, mechanical explanations
for the evolution of complex biochemical systems,
then these matters will remain within the purview
of the scientific method. They will still
be teachable in science class.
But if
the Designists are right, and there is no natural
explanation, no process of mechanical causation
that can possibly lead to the automatic evolution
of complex biochemical systems, then at that moment
the subject ceases to be science at all, and becomes
either history (what did the Designers do and why
did they do it?) or theology (what does God mean
by all this?).
That's
fine. There are lots of subjects in this world
that are worth studying, and in which true and valuable
things can be discovered, which are not and cannot
be science.
But when
you purport to teach science in school, the subject
you teach had better be science, and not somebody's
religion in disguise.
That's
the problem with both sides in this squabble.
They are both functioning as religions, and they
should stop it at once.
If both
sides would behave like scientists, there wouldn't
even be a controversy, because everyone would agree
on this statement:
