William Dembski thought Baylor University would be the perfect place
to
investigate a scientific alternative to Darwinism. He didn't know he'd
be
crucified for his cause.
In the beginning, there was a bang. A very big bang.
Nothing exploded
into something. Quarks and leptons collided violently in an intense
fireball of plasma. As the plasma expanded and cooled, the collisions
became less violent, and particles joined together to form protons
and
neutrons and electrons, then nuclei and atoms and molecules. Huge clouds
of
these particles coalesced into galaxies of stars and planets, still
expanding, always expanding, away from the central point of the explosion.
On one particular planet, in a very ordinary galaxy,
molecules somehow
formed living cells. And these cells linked together to become organisms,
some of which had certain genetic mutations that better enabled them
to
survive and replicate in the primordial atmosphere. Over the next,
oh,
billions of years, the fittest of these organisms evolved into plants
and
fish and amphibians and birds and dogs and cats and apes and humans--all
thanks to the whims of chance and the laws of nature. If the pull of
nuclei
were slightly stronger, if the force of gravity were slightly weaker,
if
the speed of universal expansion were off just a hair, if the genetic
mutations had been a little bit different, we wouldn't be here.
It's a fanciful story, but it's the best
one that modern science has
come up with so far to explain human existence. A small cadre of
philosophers, scientists, and mathematicians, however, have come to
the
conclusion that it's a little too fanciful, that perhaps there is a
better
explanation for the origin and diversity of life, that perhaps that
explanation involves an intelligent designer, a.k.a. God.
It's not a new argument. Eighteenth-century British
natural theologian
William Paley gave the intelligent-design theory its most memorable
metaphor: Happening upon a watch, one would notice that its various
parts
work together for a purpose, that the cogs and springs and gears produce
motion, and that the motion is regulated to indicate time. We would
infer
from the watch that it was crafted by a watchmaker. Paley argued that
living organisms are more complicated than watches "in a degree which
exceeds all computation," and that we, too, must therefore be the products
of some grand watchmaker, an intelligence.
Since the dawn of Darwinism, Paley's watchmaker analogy
has been
dismissed as a quaint notion of a much simpler scientific time. Darwin's
theory of natural selection explained that the design we see in nature
and
in ourselves is merely an illusion: What appears to be design is not,
in
fact, the product of a designer, but the result of a long and undirected
history of evolution in which organisms became better and better adapted
to
their environments. Darwinism forever separated science and religion.
Religion was a matter of faith; science, a matter of natural causes,
observable fact, empirical evidence. Sure, you could believe in God
if you
wanted to, but you certainly couldn't look for him to reveal himself
in the
natural world.
But intelligent-design theorists are bringing religion
back into the
laboratory, adding bite to Paley's old watchmaker argument, attempting
to
show--with mathematical theories and biological examples--that a designer
can be empirically detected. This has mainstream scientists hopping
mad and
may lead to the most intense battle between science and religion since
the
Catholic Church put Galileo under house arrest for suggesting that
the
earth was not the center of the universe.
The first major skirmish has already taken place
at Baylor University,
where William Dembski, a leading proponent of intelligent design, was
demoted from his position as director of a center set up to study the
theory. The last fight may be on your local school board.William Dembski
wasn't always a religious man. The only child of a college biology
professor (who, in fact, didn't question Darwin's theories) and an
art
dealer, he spent six days a week at an all-male Catholic preparatory
school
in Chicago. He went through the motions at school, but he didn't buy
into
Christianity. "Any sort of God who was behind it all, who we were
accountable to, who really cared for us, with whom we could have any
connection, that was just off my radar," Dembski says. That is, until
he
came upon his life's first rough spot.Dembski was always a good student,
especially in math. He finished high school a year early, completing
a full
course of calculus in just one summer. The 17-year-old tested into
some
advanced mathematics courses at the University of Chicago, but he struggled
in them. He was doing fair, but he wasn't used to doing fair. He couldn't
handle the disappointment.
Dembski was having trouble outside of class as well.
His experiences as
an only child who spent most of his time in the insular world of a
boys'
school had not prepared him for college life. His social skills, Dembski
admits, were a bit lacking. He dropped out of school and went to work
in
his mother's art dealership business. He built crates and typed letters,
but mostly he just floundered. "It was just not a very happy time in
my
life," he says, "and I guess when you're not very happy, you start
looking."
He read the Scriptures, trying to understand the
faith. And he read
creationist literature, trying to understand the world around him.
He had
always had a sneaking suspicion that Darwinism was an inadequate theory,
and although he could not believe the doctrine of literal creationists,
their criticisms of evolution fueled his active young mind. He went
back to
school, studying statistics at the University of Illinois and adding
that
knowledge to his developing disbelief in Darwinism. It seemed to him
statistically improbable that natural selection could produce the diversity
of life all around him. Still, he hadn't come up with an alternative
theory.
Then, in 1988, he had a eureka moment. At a conference
on randomness at
Ohio State University, a statistician concluded the event by saying,
"We
know what randomness isn't. We don't know what it is." It made sense
to
Dembski. If God is the creator of the universe, then there should be
order
in the world, not randomness. Darwinists were having so much trouble
defining the randomness inherent in evolutionary theory because life
was
essentially not random. It was designed. And randomness could be understood
only in terms of that design. "That insight really has propelled me
all
these years," Dembski says.
Armed with Christian faith, Dembski found that he
could be happy in the
world of academia. In fact, he's been there ever since his religious
conversion. In all, he has earned a B.A. in psychology, an M.S. in
statistics, and a Ph.D. in philosophy from the University of Illinois;
a
Ph.D. in mathematics from the University of Chicago; and a master of
divinity from Princeton Theological Seminary. He has also done postdoctoral
work in mathematics at MIT, in physics at the University of Chicago,
and in
computer science at Princeton. But his relationship with academia would
not
always be pleasant. Dembski's theories were taking him further and
further
afield from mainstream science. His mathematics were leading him to
the
same place that his faith had. To his colleagues, this wasn't science;
it
was religion. We distinguish between intelligent and natural causes
every
day--every time a detective investigates a possible homicide, every
time an
archaeologist picks out an arrowhead from a pile of rocks, every time
radio
astronomers at the Search for Extra-Terrestrial Intelligence listen
for
patterns in the noise coming from outer space. In these cases, modern
science doesn't have a problem assuming that some intelligent being
is
responsible for the evidence--a human, even an alien. But if you try
to
distinguish between intelligent and natural causes in basic biological
systems, things get a little messier. If you find intelligence in biology,
then who or what was the intelligent designer? It's a question science
doesn't want to pose, let alone answer. But Dembski contends that if
he can
codify the process by which we recognize intelligence in other fields,
he
can justifiably apply that process to biology. If he can codify that
process, he says, intelligent design is not a matter of religious belief
but a matter of following the evidence wherever it leads. Such a
codification is Dembski's contribution to the intelligent-design movement,
and his claim to fame. It is an explanatory process that can be used
for
judging objects, events, and information. It begins by ruling out chance
and natural law as explanations, and then infers design.
The first step in the process is what Dembski calls
contingency. In
other words, something that is designed must be compatible with natural
law
but not required by it. Something that is required by natural law leaves
no
room for the choices inherent in design. It is just following orders.
The second test is for complexity. Here, Dembski
turns to the sci-fi
movie Contact, based on a novel by Carl Sagan, for an example. In the
movie, Jodie Foster and her radio astronomer friends at SETI receive
a
signal of 1,126 beats and pauses representing all the prime numbers
from
two to 101. They interpret the signal to be a sign of extraterrestrial
intelligence. But if they had received a sequence of only the first
three
prime numbers, they would not have jumped to the same conclusion. Any
random radio signal might happen to emit this sequence by pure chance.
Mathematically speaking, this is a probability argument. The short
sequence
is simply not complex enough to be improbable as a result of chance.
But complexity by itself isn't enough. The final
filter is for
specification. Any particular sequence of 1,126 beats and pauses is
highly
unlikely. The sequence in Contact was special not just because it was
complex, but because it contained an independent pattern: increasing
prime
numbers.
Voila. If something is contingent, complex, and specified,
according to
Dembski, we can infer that it is the product of intelligence. Dembski
calls
it the specified-complexity criterion.
The next step for intelligent-design theorists is
to apply the
criterion to biological systems. They start small, with bacteria and
their
proteins, to keep the probability computations manageable. But the
idea is
that if they can prove that life's subsystems are designed, then they
can
prove that the whole system is designed.
The bacterium's flagellum may be intelligent design's
favorite
subsystem. A flagellum is a whip-like outboard motor, complete with
an
acid-powered rotary engine, O-rings, and a drive shaft. "The scientific
community has come up short with any sort of plausible, detailed
explanation of how you could have gotten something like this by purely
natural causes," says Dembski, "and when you start applying the sort
of
methods that I've developed, it clearly indicates design."
A flagellum is compatible with natural law but not
required by it;
after all, there are bacteria without flagella. It is specified in
the
sense that its pattern of parts performs a specific function. And it
is
complex not just in the sense of its machinelike combination of parts,
but
also in the improbability of its arising by chance. In fact, Michael
Behe,
the biochemist who most famously made the case for design in the bacterial
flagellum, contends that it would be virtually impossible for the motor
to
come about by mutation and natural selection.
Behe calls the flagellum an irreducibly complex system.
In other words,
its parts are so interrelated that if one part were taken away, the
entire
system wouldn't work. A mousetrap, for instance, is irreducibly complex.
Take away the platform, the hammer, the spring, the catch, or the holding
bar, and it is impossible to construct a working mousetrap. Similarly,
if
you take away any one of the 50 proteins required in the bacterial
flagellum, the motor ceases to work. Behe's argument is that the flagellum
is too complex to arise in one single mutation and then be acted upon
by
natural selection, and that the undirected nature of the Darwinian
mechanism could not support a gradual accumulation of the necessary
proteins. Just one of these proteins offers no survival and reproductive
advantage. How could nature know to preserve it for future generations?
How
could nature know that the bacterium was in the process of building
itself a motor?
Dembski is looking to apply his specified-complexity
theory on an even
more microscopic scale than the bacterial flagellum: that of DNA. The
precise sequence of nucleotides in DNA conveys the information necessary
to
build proteins. The origin of this information has become the Holy
Grail of
origin-of-life biology. Mainstream science is looking for an algorithm
or a
natural law to account for it, but Dembski says that this DNA encoding
is
complex, specified information if ever there was any--and thus indicative
of intelligent design. Natural causes cannot originate information,
Dembski
argues via his complicated mathematical proof, the Law of Conservation
of
Information. It's a somewhat circular argument: Natural laws and algorithms
cannot create complex, specified information, because they cannot create
anything that is not required by natural law. Chance can generate complex,
unspecified information or simple, specified information, but not
information that is both complex and specified.
It is for this law that Rob Koons, an associate professor
of philosophy
at the University of Texas, calls Dembski the "Isaac Newton of information
theory." It may be that intelligent design will revolutionize science
just
like Newtonian physics did. It may also be that this is just the perfect
way to evangelize a generation of Americans who put their faith in
science
without entirely understanding it. William Dembski met Baylor University
President Robert Sloan in the summer of 1996, when he was teaching
Sloan's
daughter at a Christian-study summer camp not far from Waco. Sloan,
who is
the first Baptist minister to serve as Baylor's president in more than
30
years, had read some of Dembski's work. "He liked my stuff," Dembski
recalls. "He made it clear that he wanted to get me on the faculty
in some
way."Three years later the president offered Dembski not just a position
at
Baylor but a whole center dedicated to studying the relationship between
science and religion and to furthering Dembski's work in intelligent
design. It would be named after Michael Polanyi, a Hungarian chemist
who
questioned the idea that the world could be explained through natural
laws
alone. It was a big step for intelligent design, the first center of
its
kind at a major research university, a huge inroad into mainstream
academia.
The Polanyi Center was established quietly in October
1999. Dembski and
his like-minded colleague Bruce Gordon were hired outside the traditional
academic channels of a search committee and departmental consultation.
Dembski says that he did meet with some faculty, both before and after
Baylor hired him. But the vast majority of them were unaware of the
existence of the center until its Web site went online and scientists
outside the university began sending incredulous e-mails to their
colleagues at Baylor. What, they asked, was this? Had Baylor gone
fundamentalist? Would they be teaching creation science instead of
evolution in their biology classrooms? The Baylor scientists, already
sensitive to their university's religious mission, were now the
laughingstock of the scientific community, and they didn't like it.
"When you say Baylor now, people are going to go,
'Oh, yeah, they have
that creationist center,'" says Charles Weaver, a professor of psychology
and neuroscience at Baylor and one of the most outspoken critics of
the
Polanyi Center. "We fought that as a city for a long time: 'Waco. Oh,
you
guys are the crazy ones with Koresh.'" He worries that the Polanyi
Center
and Dembski's association with the intelligent-design movement will
discourage promising premed students and respected faculty from coming
to
Baylor.
Baylor Provost Donald Schmeltekopf defends the university's
actions by
pointing out that there are more and more people in academia interested
in
questioning the naturalistic assumptions of the scientific establishment
and that Dembski is one of the most visible among them. "We thought
it
would be an interesting thing for Baylor to get into the conversation
and
to be a participant," he says.
But Weaver says Baylor faculty members have been
asking these questions
about the relationship between science and religion for years in the
school's interdisciplinary Institute for Faith and Learning. "The inference
that some of us have drawn is that...we must have come up with answers
that
aren't those we were expected to come up with," says Weaver, who is
a
Presbyterian elder. "My faith background is one of asking lots of questions
and living with a lot of doubts, and those may not be qualities that
are
valued at Baylor anymore. It may be that those of us with certainties
are
better adapted for the environment."
In any case, Schmeltekopf's conversation was about
to turn into an
argument, and a nasty one at that. In April, Dembski's Polanyi Center
hosted a conference on naturalism sponsored by the Discovery Institute,
a
conservative think tank where Dembski is a fellow, and the Templeton
Foundation, whose moneys have gone a long way to bankroll the
intelligent-design movement. The conference sought to answer a very
unusual
question: Is there anything beyond nature? An impressive collection
of
scientists from all over the world attended the conference, among them
Nobel Prize-winning physicist Steven Weinberg. Of course, Weinberg
titled
his presentation "No," a straightforward answer to the conference's
central
question. And other speakers announced that they were going to give
their
honoraria to organizations that promote the study of evolution in schools.
Baylor faculty, by and large, boycotted the conference
altogether. But
that wasn't all. Just days after the naturalism conference, the faculty
senate voted 27-2 to dismantle Dembski's center. If there was to be
a
center studying the intersection of science and religion at Baylor,
they
held, it should be rebuilt from the ground up--with faculty input.
In an
editorial published in the Houston Chronicle, President Sloan charged
that
this uproar over faculty input was a cover for the real issue: the
substance of the work being done by the center. "In my experience,"
he
wrote, "people often object to 'the way things were done' as a rhetorical
substitute for what was done." Sloan refused to dissolve the Polanyi
Center, citing issues of censorship and academic integrity.
He hit the nail on the head. A lack of input might
have annoyed the
faculty, but it was the center's promotion of intelligent design that
made
them angry. Dembski claims to be doing science, a science that hopes
to
question the very validity of naturalism and give Darwinism a backseat
to
design. And that is something that Baylor's mainstream scientists cannot
abide. "You can always look at something and say, 'That's something
that
God did,'" says Weaver. "Well, what can I do to prove you wrong?...If
I
can't prove your theory incorrect, it doesn't necessarily mean that
it's
wrong, but it means it's not science."
Weaver says that intelligent design is little more
than an ego trip.
How do we know a biological system has been intelligently designed?
Because
it's designed the way we would have designed it, in a way that we can
understand it. "That's a nice little egotistical thing, isn't it?"
he says.
"It's designed to make us feel more comfortable. We do best when we
believe
ourselves to be at the pinnacle of creation. And it doesn't have much
to do
with theology; it has much more to do with our insecurity as a species."
Intelligent design has been completely ignored in
professional
literature, Weaver says. No real scientists take it seriously. "Dembski's
got a whole long list of places where he's written articles and published
books, and none of them are peer-reviewed. They're not done in
scientifically or philosophically respectable places," Weaver says.
"We
judge things in the academic world not by how many books are sold at
Waldenbooks," but by what a scientist's peers think of his work. Dembski's
peers in mainstream science have hardly even dignified him with a response.
The famous Harvard paleontologist Stephen Jay Gould, who visited Baylor
in
the wake of the Polanyi Center controversy, dismissed intelligent design
as
nothing more than modern-day creationism.
But Charles Garner, an organic chemistry professor
at Baylor who says
he prays with students when they come to him with problems and criticizes
evolutionary theory in class, argues that it would be virtually impossible
to get intelligent-design articles peer-reviewed fairly by a pro-evolution
scientific establishment. "Remember," he says, "you're going to be
upsetting people's worldviews with this stuff."
Sloan wouldn't shut down the center, but he had no
problem holding
Dembski's work up to the light of peer review, especially if it would
help
smooth things over with the faculty. He assembled a group of nine
biologists, philosophers, science historians, and theologians--primarily
from other universities--to look into the legitimacy of the center
and
intelligent design. Dembski was furious. The Baylor administration
knew his
work; he was hired because of it. Now, they were going to risk his
academic
reputation with a very public review by scholars he wasn't even sure
were
qualified to assess his work. "The peer-review committee, from my
perspective, was called for purely political motives, to assuage the
angry
faculty," he says, "but in doing that they put me in the frying pan."
Surprisingly, Dembski emerged relatively unscathed.
The review
committee recommended an advisory committee to oversee Baylor's science
and
religion program and removed the Polanyi name from the center (even
though
Dembski claims he cleared the use of the name with Polanyi's son).
But
ultimately the outside scholars concluded that "research on the logical
structure of mathematical arguments for intelligent design...have a
legitimate claim to a place in the current discussions of the relations
of
religion and science."
Dembski was ecstatic. He issued a press release that
stated in part:
"Dogmatic opponents of design who demanded the Center be shut down
have met
their Waterloo. Baylor University is to be commended for remaining
strong
in the face of intolerant assaults on freedom of thought and expression."
Any progress that the review committee had made in
soothing faculty
concerns was undone in the space of two sentences. These were fighting
words. "In academic arguments," says Weaver, "we don't seek utter
destruction and defeat of our opponents. We don't talk about Waterloos."
The Baylor administration gave Dembski a chance to
retract, or
"contextualize," his comments, and when he refused, he was demoted.
They
cited a lack of "collegiality" that compromised his ability to serve
as
director of the center. The center that had no name now had no leader
either. "We certainly didn't demote him because of positions he has
taken,"
says Schmeltekopf. "That had nothing to do with it. We just had to
move
forward here."
It's true. Dembski was not demoted because of his
positions. He was
demoted because his positions had become a political hot potato. Initially
Dembski thought that if an intelligent-design center could be successful
anywhere, it would be at Baylor. Now, he thinks that if an
intelligent-design center could be successful at Baylor, it could succeed
anywhere. "I think what you've got at Baylor is...this whole history
of the
Southern Baptists with this moderate-fundamentalist controversy and
split,"
Dembski says. "And Baylor is--I didn't fully realize this--the bastion
for
the moderates where anything that smacks of fundamentalism, creationism,
just sends people through the roof."Baylor may be the bastion of Baptist
moderates, but some of these moderates have accused President Sloan
of
leaning toward the fundamentalist end of the spectrum. It is certainly
difficult to see how his administration could have been blind to the
fact
that intelligent design comes with a political agenda that is far from
moderate. The very way in which it formulates its scientific questions
seeks to tear apart the Darwinian underpinnings that influence our
laws,
our public policies, our economic systems, our psychological theories,
our
schools, our sense of who we are--in short, our entire worldview. If
there
is a designer, do we have obligations to that designer? What are they?
Do
we have an intrinsic sense of morality? Have we been designed to operate
best within certain constraints? "Every scientific discipline is going
to
have to be rethought if Darwinism and naturalism are thrown seriously
into
question," says Dembski. "I think the implications are huge."
If the science is sound, then perhaps we should be
willing to rework
our worldviews. But Baylor certainly was not willing to lead the way.
"One
of the things we were very clear about from the beginning," says
Schmeltekopf, "was that the work of Dembski and Gordon did not have
underneath it a political agenda of some kind; that is, to get into
textbook wars and creationist politics and that kind of thing."
To that end, Baylor administrators pressured Dembski
not to attend a
May bipartisan congressional briefing by the Discovery Institute's
intelligent-design program, the Center for the Renewal of Science and
Culture. Dembski's colleagues presented the case for intelligent design
and
how it could help resolve the debate over the teaching of origins in
public
schools.
Dembski was surprised by Baylor's limitation of his
"academic freedom."
He had made no secret of his association with the Discovery Institute,
which considers the "wedge strategy" one of its primary projects. The
wedge
strategy is a term coined by Phillip Johnson, godfather of intelligent
design and author of the popular Darwin On Trial. The metaphor portrays
mainstream science as a seemingly impenetrable log that can be cracked
with
the sharp edge of a wedge. The sharp edge of the Discovery Institute's
wedge is designed to separate modern science's naturalistic bias from
scientific fact. Once this crack has been made, Johnson can pound in
the
thicker parts of the wedge--including intelligent design, its cultural
implications, and even the Bible--until eventually the log of mainstream
science is split wide open. Johnson considers Dembski to be a key wedge
figure.
Dembski also makes no bones about his personal position
on textbooks.
"My commitment is to see intelligent design flourish as a scientific
research program," he says. "To do that, I need a new generation of
scholars willing to consider this, because the older generation is
largely
hidebound. So I would like to see textbooks, certainly at the college
level
and even at the high-school level, which reframe introductory biology
within a design paradigm." He doesn't, however, want to legislate these
ideas. "I think they're powerful enough that once they get in circulation,
they'll win on their own."
He might be right. Academia may not be embracing
intelligent design,
but the general public, it seems, is primed for it. Gallup polls over
the
last decade have shown that only about 10 percent of Americans believe
in
the scientists' definition of evolution via strictly chance mutation
and
natural selection. Nearly everyone else believes that God created life,
either directly or by guiding the process of evolution. Last year in
Kansas, the state school board voted 6-4 to no longer include evolution
in
statewide science tests. Intelligent design will likely prove to be
a
popular theory for the majority of Americans, especially because the
theory
can be applied to many faiths. Even though most intelligent-design
researchers, like Dembski, come from a Christian background, the theory
itself only detects a designer; it doesn't presume to know anything
about
that designer. Hence, Jews, Muslims, even agnostics, are signing on.Sitting
at the dining-room table in his ranch-style home just outside of Waco,
William Dembski looks more like a scientist than a minister. He's thin
and
stern, with a long, narrow face that mumbles through complicated
mathematical theory without taking a breath. Every so often, he loses
his
train of thought and apologizes, saying he is quite tired. One assumes
the
exhaustion is a product of the ordeal at Baylor, but then a screaming
toddler, recently awakened from her nap, comes running into the room
to
attach herself to her father's leg. Hot on the toddler's heels is Dembski's
wife, her belly swollen with twins that will be born any day. It is
clear
that the late nights are a result of concerns much closer to the
heart.Dembski spends most of his time at home with his family these
days,
even though he still has a five-year contract as an associate research
professor at Baylor. He doesn't like going to the university's campus.
He's
much more comfortable here, surrounded by his stretch of land that
came
complete with a horse and a fishing pond. It's the perfect place to
ponder
life's great questions, at least when the toddler is asleep. And center
or
no center, there is still much work to do.
"What if science itself is coming to the place where
it says we got
some things wrong and, in fact, things that we ended up dismissing
in
religion now have to be taken seriously?" he asks. What if "that
intelligence in the world that your religious faith is talking about
has
an ally?" What if?
