A Review Article: Darwin’s Black Box

Darwin’s Black Box by Michael J. Behe. New York: Touchstone,

In recent years, one of the most strident debates in American
public policy is whether or not evolution should be taught exclusively
in government funded schools. Some school boards have attempted to
require the teaching of creationism alongside of evolution; others have
simply tried to require a disclaimer that mentions other theories of
origin besides evolution. United States courts have consistently held
that the religious nature of creationism excludes it from mention in
government supported schools. Some have argued, however, that these
decisions do not mandate an “evolution-only” curriculum. In fact,
in a
recent story about the Supreme Court’s refusal to hear a case on one
such issue, USA Today noted that “the panel did not rule out
the possibility that a school board could require some type of disclaimer
stating that evolution was not the only accepted explanation of the origin
of life.”1
Perceived loopholes such as these have spawned a new movement
in the explanation of origins, called the Intelligent Design movement.
This movement is an attempt to open science and the secular world up
to “all possible explanations [of origins]—including design by
an intelligent
agent.”2 The Intelligent Design movement is beginning to
gain recognition among Christians as a potentially viable alternative to
evolution as taught in public schools, as demonstrated in a recent
group of articles in Christianity Today published under the heading, “The
Origins Debate.”3 The Intelligent Design movement was begun
by attorney Phillip Johnson.4 Johnson has written several books attempting
to point out the philosophical agenda behind Darwinism
and to demonstrate that Darwinists have been less than honest in their
approach and argumentation.5 Although Johnson may be the father of
the Intelligent Design movement, he is by no means its only advocate.
Biochemist Michael Behe, mathematician William Dembski,6 and
others have joined the Intelligent Design approach. An important
book in the Intelligent Design movement is Darwin’s Black Box by
Michael Behe.
Darwin’s Black Box demonstrates two important truths. First,
Behe shows the fallacy of Darwinian evolution. Second, Behe also implicitly
proves another truth: the inherent deficiency of natural theology.
But having shown clearly that Darwin’s theory is scientifically
impossible, Behe does not conclude that our Lord and Savior Jesus
Christ created the earth in six literal days. Instead, he steadfastly clings
to an evolutionary model and an old earth. Furthermore, he does not
argue that the failure of Darwinism proves the existence of God or
even a god. Instead, he concludes that the evidence he presents argues
for “intelligent design.” Whether that designer is God or someone
else
is an open question.
SUMMARY
Darwin’s Black Box is a challenge to Darwinian theories of evolution.
Although Behe is an evolutionist and sees no problem with oldearth
theories, he is unsatisfied that Darwinism (which explains the
origin of all things from common ancestry through natural selection
working on variation) can explain the complexity of life at the molecular
level.7 He concludes that Darwinism is “incomplete.”8 Since Darwinism
is incapable of explaining the complexity of the molecule
(among other problems), Behe proposes that science be allowed to
postulate an “intelligent designer” in certain cases.
The central thesis of Darwin’s Black Box is that molecular processes
and structures are “irreducibly complex” and therefore could not
have developed through natural processes. As a result, they evidence
“intelligent design” and therefore argue strongly for a designer.
Furthermore,
Darwinists have utterly failed to explain these irreducibly
complex systems. “Irreducible complexity” (a concept apparently
developed
by Behe himself) is “a single system composed of several wellmatched,
interacting parts that contribute to the basic function,
wherein the removal of any one of the parts causes the system to effectively
cease functioning.”9 An example of an irreducibly complex item
(cited throughout the book) is a mousetrap. It is irreducibly complex
because a removal of any part renders the entire contraption useless.
Therefore, it could not have “evolved” into its present state by
continuous
improvement. No one can catch a few mice with a wooden
platform, then add a spring and catch a few more, then add a metal
hammer and catch a few more and so on until the modern mousetrap
“evolves.” Behe takes this same idea and shows how biochemical systems
could not have evolved because, like the mousetrap, the parts are
useless unless all the parts are present. This is what Behe means by “irreducible
complexity.” The bombardier beetle and the eye (both
chapter 2), the cilium and flagellum (chapter 3), blood clotting
(chapter 4), RNA (chapter 5), the immune system (chapter 6), and
AMP—a key component in DNA—(chapter 7) are all developed as
examples to refute, through irreducible complexity, the idea of Darwinian
evolution.
Having demonstrated the irreducible complexity of biochemical
systems, Behe turns in section 3 (chapters 8–11) to consider how irreducible
complexity argues for intelligent design. Although Behe does
not directly define “intelligent design,” he defines design alone
as “the
purposeful arrangement of parts.”10 By modifying the word design
with the word “intelligent,” Behe appears to be commending a personal
active being who ordered the parts in the purposeful arrangement
they evidence. Thus, the idea of an intelligent designer is an
inference drawn from the reality of irreducibly complex systems. Since
they could not have developed naturally, someone must have developed
them intentionally. He concludes that the best explanation for the development
of life is that biological systems were
designed. He writes,
To a person who does not feel obliged to restrict his search to unintelligent
causes, the straightforward conclusion is that many biochemical systems were
designed. They were designed not by the laws of nature, not by chance and necessity;
rather, they were planned.”
11
As was previously noted, design means “the purposeful arrangement of
parts”12; however, Behe admits that this definition allows almost anything
to evidence design.13 This is no problem for a recent creationist,
but for Behe (not to mention more thoroughgoing evolutionists), this
is still too broad. Therefore, he attempts to propose a more refined
methodology for detecting design.
For discrete physical systems—if there is not a gradual route to their
production—design is evident when a number of separate, interacting
components are ordered in such a way as to accomplish a function beyond
the individual components. The greater the specificity of the interacting
components required to produce the function, the greater is our confidence
in the conclusion of design.14
Thus, according to Behe, Darwinian evolution should be considered
first. If there is no evidence that a system “evolved” by continuous
random mutation, we should look to see if removing one part of the
system would render it useless (like a mousetrap without a spring). If
so, it was designed, and the more interdependent the system, the more
confident we can be that it was designed.
But what does intelligent design communicate about the designer?
On this point Behe argues that “inferences to design do not require
that we have a candidate for the role of designer.”15 In fact, he even
allows for a naturalistic explanation of the designer. For instance, he
cites the theory of Francis Crick, a very important scientist who discovered
the double helix structure of DNA. Crick has theorized that
“life on earth may have begun when aliens from another planet sent a
rocket ship containing spores to earth…. He judges the undirected
origin of life to be a virtually insurmountable obstacle, but he wants a
naturalistic explanation.”16 Behe concludes that “the separateness
of the spheres of science versus philosophy and religion is as it should
be.”17 Thus, his purpose is to open the door for supernatural explanations
in science, not to bring science under the lordship of Christ.
THE AUTHOR
Michael Behe is eminently qualified to address the subject of molecular
biology. He is Professor of Biochemistry at Lehigh University
(back cover). Even Richard Dawkins, a leading atheist and popularizer
of Darwinism, is forced to acknowledge Behe’s credentials as a credible
scientist.18 As previously noted, Behe is unwilling to repudiate evolution
and even Darwinism in certain instances.19 Although scientific in
his outlook and evolutionary in his approach to science, Behe is also
Catholic by upbringing20 and choice.21 Long ago he reconciled his
Catholicism with evolution and concluded that one could hold both
to be true (a position Pope John Paul II recently espoused publicly).22
Therefore, Behe’s belief in God as understood through his Catholic
theology serves as an informing context for the conclusions he draws
from science. Stated another way, he became a theist before he became
a scientist and therefore his belief in God was not compelled by the
evidence for intelligent design. Richard Dawkins implicitly alleges bias
when he notes that Behe is a senior fellow at the Center for the Renewal
of Science and Culture, which is an organization designed to
combat the cultural decay caused by naturalism.23 Dawkins notes further
that Behe speaks at many religious conferences.24 Therefore, it is
not unfair to allege a predisposition toward a supernatural explanation;
however, to prove that Behe’s presuppositions biased his work requires
impeachment of his credentials and/or his written work. This is true
because Behe maintains that “the conclusion of intelligent design flows
naturally from the data itself—not from sacred books or sectarian beliefs.”
25 Although Dawkins has tried to refute Behe’s work, the examples
Dawkins uses for his attempt at refutation are irrelevant.26
THE INTELLIGENT DESIGN MOVEMENT
Intelligent design is a middling position of sorts between naturalism
and supernaturalism. It allows one to postulate the intervention of
a designer when naturalistic explanations seem to fail; furthermore,
since the designer remains anonymous, the position can be considered
scientific rather than religious. This allows the one postulating intelligent
design to argue for whatever designer he or she chooses.
Intelligent Design is very controversial. Naturalistic scientists do
not like it because it
appeals to an argument from ignorance: If we don’t
know how it happened, then God, alias Intelligent Designer did it. But this
is no argument. If the origin of life is explained in the future, then Behe’s
case is destroyed. Worse, Behe’s God is lazy since he only does things
that science can’t explain.27
Educators and their attorneys have warned that this movement “attempts
to strip creationism of its religious connotations by recycling it
under the name ‘intelligent design’ and positing that humans are
the
product of purposeful design. (But saying nothing about the ‘designer.’)”
28 They warn that this is a more sophisticated attempt by the
“Religious Right” to reintroduce creationism into the public schools
through a legal loophole. In 1987 the Supreme Court ruled a Louisiana
law requiring equal time for creationism in public schools was unconstitutional;
however, the high court “said public schools could
lawfully teach ‘a variety of scientific theories about the origins of
mankind’
if they were non-religious in nature.”29 Darwin’s Black Box is
a book feared to be able to exploit this loophole.
EVALUATION
Style
Judged by its style, Darwin’s Black Box is an amazing
accomplishment. Technical writing of all kinds depends on the use of technical
jargon and an assumption of prior knowledge in order to make the examples
intelligible to the uninformed reader. For instance, a certain
amount of knowledge of the Hebrew language is needed to understand
a Hebrew grammar textbook. The same is true in scientific writing.
Scientific explanations are needed in order to make a convincing case
to scientists. Therefore, it would seem nearly impossible to write a
book technical enough to satisfy the mind of the scientist and accessible
enough to convince those untrained in science. Behe, amazingly,
has been able to do both. By using simple but powerful analogies to
everyday life (like the mousetrap), Behe is able to explain the minute
complexity of biochemistry to the uninitiated while at the same time
providing enough information to demonstrate that these examples pass the test
of scientific technicality. Furthermore, for those uninterested in or unable
to understand the technical sections, the editors have marked these sections
off with little black boxes. This helpful addition allows the reader to skim
or skip those sections when appropriate.
Argumentation
Since I am not a scientist, it is impossible for me to critique or
even fully understand Behe’s examples. However, since scientists have
taken his work seriously30 and have not been able to discredit his examples,
31 it appears that the scientific information as explained in this
book is correct. While I cannot attest to the details of the scientific ex-planations,
the rest of the book is clearly well argued. The
argumentation is tight and logical. It builds inductively from the problems
that Darwinism has generally to the enormous problems Darwinism has with modern
biochemistry.
Despite the new emphasis for Intelligent Design, very few people
find Behe’s work wholly satisfying. Scientists have criticized him for
a “god-of-the-gaps”32 hypothesis and for undermining the modern basis
for science. Atheistic and theistic scientists alike have voiced this criticism,
although some theistic scientists have welcomed Behe’s approach.
33 Furthermore, special interest groups for nationalized
government schools (i.e., the public school system) have warned that
the Intelligent Design movement is just a sophisticated covert attempt
by recent creationists to reintroduce God into the government schools.
Finally, recent creationists have found Darwin’s Black Box lacking in
that it does not propose any method for identifying an intelligent designer.
34 They also object to Behe’s acceptance of an old earth hypothesis,
common ancestry of all living things, and acceptance of the
Big Bang theory.
It is expected that Christians who advocate a traditional evidential
approach to apologetics will enthusiastically welcome Darwin’s
Black Box.35 Because Behe has not used his work to argue for any form of
theism, his work fits in well with the evidential approach which attempts
to prove the existence of a god (theism in general) based on
physical evidence. Two forms of this argument are the teleological argument
and the cosmological argument, both of which would benefit from Behe’s
work.36 The problem with this traditional approach is that it can only establish
a high degree of probability. Furthermore, the sinful nature of people tends
to distort any evidence from the physical world so as to deny the existence
of the one true and living God. Thus, an unbeliever may find Behe convincing,
but conclude with Francis Crick that an alien from another world was the designer.
At Detroit
Baptist Theological Seminary, two of our institutional distinctives are recent
creationism and presuppositional apologetics. Recent creationism is the position
that “God recently created the
heavens and earth and all that is in them in six, consecutive, literal
twenty-four hour days.”37 This position is derived from a careful exegesis
of Scripture (primarily Genesis 1 and 2) and conforms to historic
confessions of faith such as The Westminster Confession of Faith
(1646) and the Second London Baptist Confession of 1689.38 Since
many (though not all) fundamental Baptist colleges and seminaries are committed
to recent creationism, most readers of this review will be familiar with and
sympathetic to this DBTS distinction.
Some readers, however,
may not be familiar with presuppositional apologetics, but even a cursory
discussion of it is beyond the scope of this review. All that can be said
at this point is that presuppositionalism holds that both believers and unbelievers
have certain basic beliefs (presuppositions) that inform and condition their
thinking. Presuppositionalism asserts that the defense of the faith must
surface and engage these presuppositions in order to defend the faith in a
biblical way.39
One common misunderstanding about presuppositionalism
is that there is no place for evidence or argumentation in presuppositional
apologetics. Those who follow this misunderstanding hold that presuppositional
apologetics simply tells the unbeliever he or she is wrong
and calls on him or her to repent. This is incorrect. Presuppositionalism
does not deny the usefulness of evidences nor does it demand
avoiding arguments with unbelief. What presuppositionalism argues
against is the use of evidence apart from the truth of
Scripture and Christian presuppositions.40 That is, the believer must
not allow the unbeliever to interpret evidences according to his unbelieving
presuppositions. Although Behe does not argue for the existence
of the God of the Bible, that does not mean his work is useless
to those who wish to defend the faith. As a recent creationist committed
to presuppositional apologetics, I can recommend Darwin’s Black
Box as a potentially powerful agent for disequilibrium. That is, if one
is convinced that Darwinian evolution is a proven fact, Behe’s work
can be used to show the fallacious nature of a materialistic worldview.
What one cannot do is prove the existence of God using Behe. This
book fits into a presuppositional approach in that it may be able to
move the debate from Darwinism to the philosophical worldview behind
it, namely a chance universe. If the believer is able to show the
unbelieving Darwinist that his worldview cannot account for reality in
the realm of science (or logic, morality, human freedom, or human
dignity) but that the Christian-theistic worldview can account for such
reality, then the believer can silence objections of unbelief and demonstrate
biblically to the unbeliever the truth of the gospel and his need
to repent
A word of caution should be noted in my recommendation. Inasmuch
as Behe partially demonstrates the folly of unbelief, his work is helpful.
However, his work also suffers from the folly of fallen thinking in that it
still preserves the unbiblical notion of human autonomy. In Behe’s world,
one is free to choose for himself or herself which designer designed the mechanisms
of life. Thus one is still serving the creature rather than the Creator and
is therefore in disobedience to God and at odds with reality. This is why the
Intelligent Design movement will fail even if it succeeds. Even if the idea
of design is accepted as scientific and allowed in public government run schools,
our society will still feel the continued wrath of God in increasing immorality
(Rom 1:18–32) because we have failed as
a society to give him the glory he rightfully deserves. Any proposed “intelligent
designer” that
is not the God and Father of our Lord Jesus Christ is still an idol.

30One example is the debate printed in Perspectives on Science
and Christian Faithbetween two biochemists—Braxton M. Alfred and Alice Fulton. Although both
would
claim to be Christians, Fulton is unshaken in her Darwinism, although she cannot
refute from biochemistry any of the examples offered by Behe. See Braxton M.
Alfred
and Alice Fulton, “Contrasting Views on Behe,” Perspectives

31Especially telling on this score is the reaction of Richard Dawkins. His web
site
[www.world-of-dawkins.com] contains a link to another site that purports to give
three Darwinian explanations of irreducible complexity. Two of the three involve
hypothetical
situations and the other involves a “non-biochemical example” (see
par. 8:
“Example: The Bolas Spider”). Thus all three are invalid based on
Behe’s criteria because
either they are hypothetical (and therefore “fact free science”)
or not biochemical and therefore irrelevant to Behe’s argument. See [http://www.cs.colorado.edu/~lindsay/creation/evolve_irreducible.html].
32This term is used in many articles. It refers to
a position where “God
is invoked
only when natural explanations fail” (Edward B. Davis, “Debating

p. 680).

35For instance, Hank Hannegraff,
President of the Christian Research Institute and an avowed evidentialist, has
welcomed Darwin’s Black Box as “very
strategic”
(“The Bible Answer Man Broadcast,” March 22, 2000, archived at
http://www.equip.org).
36See, for example, chapter 7, “The Cosmological and Teleological Arguments,” in
R. C. Sproul, John Gerstner, and Arthur Lindsley, Classical
Apologetics (Grand
Rapids: Academie Books, 1984), pp. 109–36. Sproul, Gerstner, and Lindsley
do not use intelligent design per se, but I am arguing that the Intelligent Design
movement fits perfectly with their evidential approach, especially with regard
to these two arguments.
37Robert V. McCabe, “Biblical Creationism” (Class Notes, Detroit
Baptist
Theological Seminary, Spring 2000), p. 15. An excellent introduction to recent
creationism
is Donald E. Chittick, The Controversy: Roots of the Creation-Evolution
Conflict (N.p.: Creation Compass, 1984).
38McCabe, “Biblical Creationism,” p. 15. Also, article 6 of the
DBTS statement
of faith reads: “We believe in the original direct creation of the universe,
a voluntary
act of God whereby for his own glory and according to His eternal counsel,
in six successive
days of twenty-four hours each, He gave existence to all things in distinction
from Himself. We oppose all forms of the evolutionary hypothesis of origins,
whether theistic or atheistic” [http://www.dbts.edu/article6.html].
39The best introduction to this method of defending the faith is Greg Bahnsen,
Always Ready: Directions for Defending the Faith (Texarkana, AR: Covenant Media
Foundation, 1996).

in the title
refers to Cornelius Van Til, who was the father of presuppositionalism. |
