Mere Creation Conference
"You Guys Lost:
Is Design a Closed Issue?
By Nancy Pearcey
The setting was one of those notoriously colorful debates over evolution that
scientists hate but the public loves. The combatants in this case were Vincent
Sarich and creationist Duane Gish. Eventually Sarich turned to Gish in exasperation
and denounced the debate as an exercise in redundancy. After all, he said, the
same debate was conducted a hundred years ago, and "you guys lost."1
In other words, Sarich was saying, creation was discredited back in the nineteenth
century by Darwin, so why are you resurrecting a dead issue?
It is commonly assumed that the battle over Darwinism was waged in the nineteenth
century, and that Darwin won the day because his theory was supported by the
scientific evidence. To cite just two examples, zoologist Ernst Mayr asserts
that "Darwin solved the problem of teleology, a problem that had occupied the
best minds for the 2000 years since Aristotle." Douglas Futuyma writes that
"By coupling undirected, purposeless variation to the blind, uncaring process
of natural selection, Darwin made theological or spiritual explanations of the
life processes superfluous."2 In the modern world,
Darwin's theory tends to be accepted by each new generation for the simple reason
that it is part of the outlook in which we are reared and educated.
Yet I suggest that there are good reasons for returning to the site of battle
and asking whether it was won fair and square. I propose to show that the battle
was not won by Darwin in the sense normally intended: I will argue that
Darwin was a turning point in biology not so much because the empirical evidence
was persuasive but primarily because his theory proved useful in advancing a
particular philosophy--a philosophy of science first of all and in many cases
a general metaphysical position as well.
In modern culture, science is accorded intellectual authority to define the
way the world "really is." The persuasive power of Darwinian theory stems from
the aura of scientific factuality that surrounds it. If it can be shown that
historically the primary motivation for advancing Darwin's cause was not so
much scientific as philosophical, then the theory loses much of its persuasive
force. For scientists have authority to tell us how the natural world functions,
but they have no comparable authority to tell us what philosophy we ought to
hold. If the motivation for accepting Darwinism was primarily philosophical,
then we in the twentieth century are justified in calling for a resurrection
of the old debate.
In this chapter, I will first examine the writings of Darwin's core supporters
in the nineteenth century. Contrary to a common misconception, Darwin did not
actually win over many contemporaries to his theory. Even those who identified
themselves as supporters often did not in fact accept his theory of natural
selection. It was not until the 1930s and 40s, with the development of the modern
synthesis (i.e., the combination of Darwin's theory with findings from genetics),
that natural selection was finally accepted as the central mechanism of evolution.
Those who insist that Darwin closed the issue are anachronistically reading
back into history the views held by most modern biologists.
Why, then, did Darwin become the focal point of debate in the nineteenth century,
even for many who did not accept his theory? The answer has to do with a shift
in the philosophy of science from an older epistemology that allowed for mind
as a real cause in nature to a new epistemology that admitted nothing but natural
causes. Darwin's theory seemed to show that a completely naturalistic account
of living things was possible; as a result, it attracted many supporters whose
main interest was in promoting naturalism, even if they shrugged off the theory's
scientific details. By probing the writings of the early Darwinists, I propose
to show that their motivation was in fact primarily philosophical.
Second, I will look briefly at those who adopted a peacekeeping strategy, seeking
to reconcile design and Darwin. What effects did their efforts have historically?
Third, I will analyze one of the most important strategies Darwin and his supporters
used in order to discredit design. As the battle became more heated, they sought
to make design implausible by casting it as perpetual miracle. In so doing,
they set up a straw man that continues to be useful to modern-day Darwinists.
Finally, I will suggest that the success of Darwin and his cohorts in the nineteenth
century had much to do with their political expertise. They understood clearly
that the battle is not only about ideas but also about institutions and power.
The Non-Darwinian Darwinians
The argument that Darwin won the day back in the nineteenth century, so why
don't we all go home, ignores a key fact: namely, that Darwin did not
win over most of his contemporaries. His theory was accepted by only a handful
of scientists for a good three-quarters of a century, gaining wider support
only after Mendelian genetics had provided a clearer understanding of heredity.
The majority of Darwin's contemporaries came to agree that some form of evolution
or development had occurred, but most championed other mechanisms and causes
to explain the process. Generally they insisted either that God was directing
the process or that it was propelled forward by some internal directing force.
Historian Peter Bowler goes so far as to suggest that the Darwinian revolution
should be more accurately labeled the non-Darwinian revolution (which
is the title of his book on the subject). Bowler argues that Darwin should be
seen as "a catalyst that helped bring about the transition to an evolutionary
viewpoint," but not specifically to a Darwinian viewpoint. Most commonly
evolution was seen as an orderly, lawful, goal-directed, and purposeful process
analogous to the development of an embryo to an adult--"the preordained unfolding
of a rationally ordered plan," often a divine plan. As Bowler puts it, "once
convinced that evolution did occur, they [Darwin's followers] turned their backs
on Darwin's message and got on with the job of formulating their own theories
of how the process worked." 3
Ironically, even those who championed Darwin's cause, and who identified themselves
as Darwinians, did not generally adopt his theory. That is, they did not accept
his proposed mechanism for evolution, which gave pride of place to natural selection.
Many were Lamarckians or speculated on other mechanisms for evolution. These
historical facts provoke a question: If even Darwin's supporters did not accept
his proposed scientific mechanism, what exactly was his appeal?
The answer is that Darwin illustrated how one might frame a completely naturalistic
account of living things--an accomplishment that was attractive to those whose
metaphysical stance was naturalistic, and to others who felt that at least science
itself should be completely naturalistic. Though his supporters did not think
Darwin had succeeded in identifying the mechanism of evolution, still he had
shown how one must reason in order to succeed eventually. He had focused
on presently observable processes (processes of "ordinary generation," as he
put it), and extrapolated those processes into the past. In short, it was not
the specifics of Darwin's theory so much as his naturalistic methodology that
attracted support.
For some time, pressure had been building to frame a naturalistic approach
to biology. Since the triumph of Newtonian physics, many scientists had announced
their intention of extending the domain of natural law to all other fields.
But the complexities of living things had defied all attempts to fit them into
any naturalistic mold. As Huxley asked plaintively in 1860, "Shall Biology alone
remain out of harmony with her sister sciences?"4
For those caught in this dilemma, Darwin came to the rescue. His goal was to
show how biology might be transformed to fit the naturalistic ideal already
dominant in other fields of science. And not only biology but also the human
sciences since, in explaining all life by completely naturalistic causes, his
theory included human origins.
Neal Gillespie, in Darwin and the Problem of Creation, sums up the point
neatly:
"It is sometimes said that Darwin converted the scientific world to
evolution by showing them the process by which it had occurred. Yet the
uneasy reservations about natural selection among Darwin's contemporaries
and the widespread rejection of it from the 1890s to the 1930s suggest that
this is too simple a view of the matter. It was more Darwin's insistence
on totally natural explanations than on natural selection that won
their adherence."5
Robert Young, in Darwin's Metaphor, makes a similar point. The principle
effect of the 19th-century debate, he writes, was not providing an acceptable
mechanism for evolutionary change. Rather it was "eliciting faith in the philosophical
principle of the uniformity of nature"--bringing "the earth, life, and man under
the domain of natural laws." From the 1860s to the 1930s, acceptance of Darwin's
theory of natural selection actually declined, while adherence to naturalism
as a foundational assumption in biology increased. As Young puts it, there was
ongoing debate about the mechanism of evolution, but "the uniformity of nature
was progressively assumed to apply to the history of life, including the life
and mind of man."6 In short, both the primary motivation
for supporting Darwin and the principle effect of his work was not so much scientific
as philosophical.
Charles Darwin
This interpretation is borne out by examining the writings of key nineteenth-century
Darwinians--beginning with Darwin himself. The typical account, certainly in
popular works, portrays Darwin as a man forced to the theory of natural selection
by the weight of the facts. But professional historians tell a different story.
Long before formulating his theory, Darwin nurtured a sympathy for philosophical
naturalism. He was therefore predisposed toward a naturalistic theory of evolution
even when the evidence itself was weak or inconclusive.
In a personal letter, Darwin describes his gradual loss of religious belief
and slide into naturalism. By the late 1830s, he writes, he had come to consider
the idea of divine revelation in the Old Testament "utterly incredible." He
had also rejected the biblical concept of miracles: In his words, "The more
we know of the fixed laws of nature the more incredible do miracles become."
This commitment to "the fixed laws of nature" preceded Darwin's major scientific
work, and made it virtually inevitable that he would interpret the evidence
through a naturalistic lens.
Gillespie notes the same progression. Once Darwin had decided, in the late
1830s, that "creationist explanations in science were useless," Gillespie writes,
then "transmutation was left as virtually the only conceivable means of species
succession." When Darwin began to consider the origin of species, "he did so
as an evolutionist because he had first become a positivist, and only later
did he find the theory to validate his conviction."7
Even when he found the theory, Darwin was quite aware that it could not be
confirmed directly. Modern Darwinians often imply that the theory is so clearly
supported by the facts that anyone who fails to concur must be intellectually
dishonest or deranged. But Darwin was not so dogmatic. He described his theory
as an inference grounded chiefly on analogy. And he praised the author of one
review for seeing "that the change of species cannot be directly proved and
that the doctrine must sink or swim according as it groups and explains phenomena."8
In an 1863 letter, he amplified by pointing out that evolution by natural selection
was "grounded entirely on general considerations" such as the difference between
contemporary organisms and fossil organisms. "When we descend to details," he
wrote, "we can prove that no one species has changed [i.e., we cannot prove
that a single species has changed]; nor can we prove that the supposed changes
are beneficial, which is the groundwork of the theory. Nor can we explain why
some species have changed and others have not."9
In other words, Darwin was quite aware that the scientific evidence was short
of compelling.
Hence the key to Darwin's own thinking is his philosophical commitment. Consider
his stance on the origin of life. In the last sentence of the Origin of Species
Darwin resorted to Pentateuchal language, speaking of life, "with its several
powers, having been originally breathed into a few forms or into one." (In a
later edition he added, "by the Creator.") But over time Darwin drifted toward
a more consistently naturalistic position, provisionally accepting the spontaneous
generation of life from inorganic material despite a striking absence of evidence
for the theory at the time. In a 1882 letter, he wrote: "Though no evidence
worth anything has as yet, in my opinion, been advanced in favour of a living
being, being developed from inorganic matter, yet I cannot avoid believing the
possibility of this will be proved some day in accordance with the law of continuity."
Here is the naturalist's faith: Darwin is confident that a naturalistic theory
will be found, not because the facts point in that direction but because he
believes in the "continuity" of natural causes.10
This belief achieved almost religious status for Darwin. Years later William
Darwin was to describe his father's attitude toward nature in near-devotional
terms: "As regards his respect for the laws of Nature," William wrote of his
father, "it might be called reverence if not a religious feeling. No man could
feel more intensely the vastness and the inviolability of the laws of nature."11
Darwin's intellectual journey seems to illustrate the adage that if one rejects
a Creator, inevitably one puts something else in its place. In Darwin's case,
he assigned god-like powers to the laws of nature.
To the end of his life, Darwin struggled with a residual belief in theism,
so there is some question whether he held strictly to metaphysical naturalism.
But there is no question that at least he held to methodological naturalism
in science. He did not argue that design was a weak theory, nor even a false
theory; he argued that it was not a scientific theory at all. In 1856 he wrote
to Asa Gray: "to my mind to say that species were created so and so is no scientific
explanation, only a reverent way of saying it is so and so."12
As philosopher of biology David Hull writes, Darwin dismissed special creation
"not because it was an incorrect scientific explanation but because it was not
a proper scientific explanation at all."13
On the other hand, when Darwin's own ideas were attacked, he defended them
by arguing that at least his proposed theory was naturalistic--which begged
the very question that lay at the heart of the controversy. As Young writes,
"Whenever [Darwin] was really in trouble . . . he appealed to the very principle
which was at issue, the uniformity of nature." Darwin's contemporaries understood
his strategy precisely. As John Tyndall said in his 'Belfast Address' in 1874:
"'The strength of the doctrine of Evolution consists, not in an experimental
demonstration (for the subject is hardly accessible to this mode of proof),
but in its general harmony with scientific thought.'"14
The underlying assumption is that genuinely "scientific thought" must be naturalistic.
And once that assumption is granted, some form of naturalistic evolution will
win the day by default.
Herbert Spencer
In his autobiography, Herbert Spencer recounts in excruciating detail the process
by which he developed a naturalistic outlook, beginning when he was a boy. Over
time, he writes, "a breach in the course of [physical] causation had come to
be, if not an impossible thought, yet a thought never entertained."15
As in Darwin's case, members of Spencer's family described his adherence to
naturalism in near-religious terms. His father drew a parallel between the son's
naturalism and the father's own religion: "From what I see of my son's mind,
it appears to me that the laws of nature are to him what revealed religion is
to us, and that any wilful infraction of those laws is to him as much a sin
as to us is disbelief in what is revealed."16
This semi-religious attachment to naturalism explains why Spencer eventually
became a tireless promoter of Darwinism. It was not because he was persuaded
by Darwin's scientific theory; indeed, he rejected Darwinism and embraced Lamarckianism.
Yet Spencer saw clearly that once he had embraced philosophical naturalism,
he had no alternative but to accept some form of naturalistic evolution. As
he puts it, having discarded orthodox Christianity, he developed an "intellectual
leaning towards belief in natural causation everywhere operating." And in that
naturalistic leaning, "doubtless . . . a belief in evolution at large was then
latent." Why latent? Because "anyone who, abandoning the supernaturalism of
theology, accepts in full the naturalism of science, tacitly asserts that all
things as they now exist have been evolved." In short, Spencer accepted naturalism
first, and then accepted evolution as a logical consequence. He goes on: "The
doctrine of the universality of natural causation, has for its inevitable corollary
the doctrine that the Universe and all things in it have reached their present
forms through successive stages physically necessitated."17
Just so: Once one accepts the philosophy of naturalism, some form of naturalistic
evolution is an "inevitable corollary." Finding a plausible scientific theory
is secondary.
In Spencer's writings we get a glimpse of the intellectual pressure that impelled
him toward a naturalistic view of evolution. "I cheerfully acknowledge," he
writes in The Principles of Psychology, that the hypothesis of evolution
is beset by "serious difficulties" scientifically. Yet, "save for those who
still adhere to the Hebrew myth, or to the doctrine of special creations derived
from it, there is no alternative but this hypothesis or no hypothesis." And
no one can long remain in "the neutral state of having no hypothesis."18
Similarly, in an 1899 letter, he writes that already decades earlier, "in 1852
the belief in organic evolution had taken deep root"--not for scientific reasons
but because of "the necessity of accepting the hypothesis of Evolution when
the hypothesis of Special Creation has been rejected." He concludes with these
telling words: "The Special Creation belief had dropped out of my mind many
years before, and I could not remain in a suspended state: acceptance of the
only conceivable alternative was peremptory."19
Here is a candid admission that Spencer was driven by a sense of philosophical
necessity--naturalistic evolution was "the only conceivable alternative" to
creation--more than by a dispassionate assessment of the scientific evidence.
Thomas H. Huxley
Thomas Huxley christened himself Darwin's and offered his natural "combativeness,"
as he put it, in service to the cause. So it may come as a surprise to learn
that Huxley was never convinced that Darwin's theory of natural selection amounted
to much scientifically. Huxley argued that the effectiveness of the mechanism
would not be proved until a new species had been produced by artificial selection.
By the 1879s he was even speculating on the existence of a "law of variation"
that would somehow direct evolution, an idea he favored over Darwin's concept
of random variations.
What, then, gave Huxley his bulldog determination to fight for Darwin? The
answer is, once again, largely philosophical. Before his encounter with Darwin,
Huxley writes, "I had long done with the Pentateuchal cosmogony." He had also
surveyed early forms of evolutionary theory, but found them all unsatisfactory.
And yet, he writes, he continued to nurse a "pious conviction that Evolution,
after all, would turn out true."20
When Darwin published the Origin, Huxley welcomed it as a vindication
of that "pious conviction." As his son Leonard Huxley writes, "Under the suggestive
power of the Origin of Species," his father experienced "the philosophic
unity he had so long been seeking."21 Huxley himself
recalls that the Origin "did the immense service of freeing us for ever
from the dilemma--Refuse to accept the creation hypothesis, and what have you
to propose that can be accepted by any cautious reasoner?"22
Apparently Huxley, like Spencer, was so eager to be freed from that dilemma
that he was willing to champion any naturalistic theory, even one he
himself found scientifically implausible, so long as it provided an alternative
to creation.
Consider Huxley's response to spontaneous generation. His son notes that "there
was no evidence that anything of the sort had occurred recently." (Louis Pasteur
had discredited all currently held theories of spontaneous generation.) Nevertheless,
his father persisted in believing that "at some remote period, life had arisen
out of inanimate matter"--not because of any scientific evidence but as "an
act of philosophic faith."23
Huxley was especially sensitive to pressures to bring biology under the naturalistic
framework that had become dominant in other fields of science. Geology had recently
been placed on a new philosophical footing by Charles Lyell, and Huxley writes
that it was Lyell's Principles of Geology that persuaded him that new
life forms must be generated by "ordinary agencies" at work today (by which
he meant natural agencies). In his words, "consistent uniformitarianism postulates
Evolution as much in the organic as in the inorganic world."24
In 1859 he wrote to Lyell: "I by no means suppose that the transmutation hypothesis
is proven or anything like it. But . . . . I would very strongly urge upon you
that it is the logical development of Uniformitarianism, and that its adoption
would harmonize the spirit of Paleontology with that of Physical Geology."25
That spirit, of course, was a consistent and relentless naturalism. As Huxley
wrote elsewhere, the "whole theory crumbles to pieces" if one denies "the uniformity
and regularity of natural causation for illimitable past ages."26
Huxley was what Bowler terms a "pseudo-Darwinian": someone who rallied to Darwin
for philosophical reasons even while remaining unconvinced of his scientific
theory. In Bowler's words, Huxley was "guaranteed" to support Darwinism because
of his "empiricist philosophy."27 Or, as Gillespie
puts it, he "leaned toward transmutation from intellectual necessity."28
Huxley expresses his philosophical credo eloquently in Man's Place in Nature
(1864): "Even leaving Mr. Darwin's views aside, the whole analogy of natural
operations furnish so complete and crushing an argument against the intervention
of any but what are called secondary causes, in the production of all the phenomena
of the universe; that . . . I can see no reason for doubting that all are coordinate
in terms of nature's great progression, from formless to formed, from the inorganic
to the organic, from blind force to conscious intellect and will."29
As he put it more simply in a 1859 speech, if the world is governed by uniformly
operating laws, then the successive populations of beings "must have
proceeded from one another in the way of progressive modification."30
In other words, if you accept philosophical naturalism, then something very
much like Darwinism must be true a priori. This explains why Huxley was
willing to do battle for Darwin, without being overly concerned about the scientific
details.
Deduction from a Philosophy
"You guys lost" may be a fair assessment of the intellectual battle in the
19th century. But the question is how the battle was lost. It is often
said that what made Darwin unique is that he provided a genuinely scientific
mechanism for evolution--that others had proposed vague or idealist causes but
in natural selection Darwin provided the first genuinely empirical mechanism.
Yet, since most of Darwin's supporters did not accept his theory, that cannot
be the reason for his success. I have argued that the battle was "rigged"--that
Darwinism won less because it fit the empirical data than because it provided
a scientific rationale for those already committed to a purely naturalistic
account of life.
Both Darwin's supporters and opponents understood that philosophical naturalism
was the central issue. Among opponents, Princeton theologian Charles Hodge wrote
an essay titled What Is Darwinism? He answered bluntly that Darwinism
is tantamount to atheism: "Natural selection is selection made by natural laws,
working without intention and design." And "the denial of design in nature is
virtually the denial of God."31 Among supporters,
Karl Vogt noted happily that Darwin's theory "turns the Creator--and his occasional
intervention in the revolutions of the earth and in the production of species--without
any hesitation out of doors, inasmuch as it does not leave the smallest room
for the agency of such a Being."32 Emil de Bois-Reymond
wrote: "The possibility, ever so distant, of banishing from nature its seeming
purpose, and putting blind necessity everywhere in the place of final causes,
appears, therefore, as one of the greatest advances in the world of thought."
To have "eased" this problem, Bois-Reymond concludes, will be "Charles Darwin's
greatest title to glory."33 And finally, August
Weismann: "We must assume natural selection to be the principle of the explanation
of the metamorphoses because all other apparent principles of explanation fail
us, and it is inconceivable that there should be another capable of explaining
the adaptation of organisms without assuming the help of a principle of design."
Apparently only Darwinism would keep biology safe from design.34
Darwin and Design
Is it necessary, however, to drive such a sharp wedge between design and natural
causes? Many if not most of the scientists in the Darwinian and post-Darwinian
era sought some kind of middle ground. They gave God a directing role in evolution
and asserted his constant supervision over the process. They located design
not in the "contrivances" of living things (to use Paley's word) but in the
laws that created those contrivances.
Gillespie calls this position nomothetic creation (creation by law) or providential
evolution, depending on how much leeway is allowed to divine initiative. This
category would include men such as Asa Gray, Charles Kingsley, the Duke of Argyll,
St. George Jackson Mivart, Baden Powell, Robert Chambers, Richard Owen. Despite
important differences among these men, they agreed that natural laws are expressions
of divine purpose, and that God or mind directs or preordains the course of
evolution. John Herschel states the position clearly: "An intelligence, guided
by a purpose, must be continually in action to bias the directions of the steps
of change--to regulate their amount--to limit their divergence--and to continue
them in a definite course. We do not believe that Mr. Darwin means to deny the
necessity of such intelligent direction."35
But Mr. Darwin did mean to deny the necessity of such intelligent direction.
The design argument pointed to characteristics of living things that seemed
analogous to the products of an intelligent mind, with its capacity for forethought,
purpose, and design. The challenge Darwin took on was to identify completely
natural processes capable of mimicking the products of a mind. Gillespie describes
Darwin's goal in these words:
"It has been generally agreed (then [in Darwin's day] and since) that
Darwin's doctrine of natural selection effectively demolished William Paley's
classical design argument for the existence of God. By showing how blind
and gradual adaptation could counterfeit the apparently purposeful design
that Paley . . . and others had seen in the contrivances of nature, Darwin
deprived their argument of the analogical inference that the evident purpose
to be seen in the contrivances by which means and ends were related in nature
was necessarily a function of mind."
Put simply, Darwin proposed to show that purposeless nature could "counterfeit
purpose."36
Hence he emphatically rejected any attempt to sneak purpose in by the back
door, so to speak. Consider his response to Asa Gray, who wedded Darwinian theory
to fairly conservative Christian theology. Gray denied that variation, the raw
material of natural selection, was random; instead he opted for a teleological
view of evolution. In fact, Gray fancied that he comprehended the implications
of Darwin's theory better than Darwin himself. In a letter written in 1863,
he confessed to a bit of cunning: "Under my hearty congratulations of Darwin
for his striking contributions to teleology, there is a vein of petite malice,
from my knowing well that he rejects the idea of design, while all the while
he is bringing out the neatest illustrations of it."37
But Darwin's response to Gray's notion of divine direction was unequivocal:
In a letter to Lyell he wrote, "If I were convinced that I required such additions
to the theory of natural selection, I would reject it as rubbish." Two years
later he wrote again to Lyell: "The view that each variation has been providentially
arranged seems to me to make Natural Selection entirely superfluous, and indeed
takes the whole case of the appearance of new species out of the range of science."
To say that variations are divinely ordained adds nothing scientifically, Darwin
went on: It "seems to me mere verbiage." He summed up his view by charging that
"Gray's notion [of guided variations] seems to me to smash the whole affair."38
Notice that Darwin's objections to providential evolution are twofold. First,
it makes natural selection "superfluous," "rubbish," "mere verbiage." Natural
selection was intended to replace design; hence, the presence of both
is redundant. As Darwin wrote in his autobiography, "The old argument from design
in nature, as given by Paley, which formerly seemed to me so conclusive, fails,
now that the law of natural selection has been discovered. . . . There seems
to be now more design in the variability of organic beings and in the action
of natural selection, than in the course which the wind blows. Everything in
nature is the result of fixed laws."39 The effort
to superimpose divine direction onto a completely naturalistic process Young
labels "theistic naturalism," an oxymoron that has resurfaced in recent debates.
Second, Darwin objected that adding divine purpose to evolution takes the discussion
"out of the range of science." The implication is that science cannot countenance
intelligent causation in any form. In Darwin's mind, divinely ordained evolution
was no different in principle from direct creation. Both were inadmissible in
science. As Hull notes, "Darwin insisted on telling a totally consistent naturalistic
story or none at all."40
Those who reformulated Darwin to accommodate design were hoping to prevent
the takeover of the idea of evolution by philosophical naturalism. They sought
to extract the scientific theory from the philosophy in which it was embedded.
But the two proved inseparable and, ironically, the effect of their effort was
precisely the opposite of what they had hoped: It sped the acceptance of philosophical
naturalism. As Hull writes, "The architects of the demise of teleology were
not atheistic materialists but pious men . . . who thought they were doing religion
a good service" in restricting God to working through natural laws. "What these
men did not realize was that by pushing God further and further into the background
as the unknowable author of natural law, . . . they had prepared the way for
his total expulsion."41
Gillespie tells the same story: The restructuring of the design argument to
adapt to evolution, he writes, was an important "step in the secularization
of science and its eventual intellectual separation from theology." The idea
of designed or directed evolution "eased a generation of often reluctant scientists
into a 'naturalistic' and ultimately positivistic world view." In this naturalistic
world view, God had no significant function and divine action was not required
for a true understanding of the world. As a result, religious belief became
"private, subjective, and artificial"; God "was, at best, a gratuitous philosophical
concept derived from a personal need."42
Once God had been reduced to a "gratuitous philosophical concept" based on
personal need, Darwin and his cohorts could afford to be tolerant toward religious
believers. In the mid-1870s, Young writes, there are signs of the "benevolent
tolerance of the victors."43 Religious believers
could be treated gently so long as they agreed that God did absolutely nothing
in the natural world studied by science. As Gillespie explains, the strategy
of relocating design from contrivances to laws "gave the game to the positivist."
It removed from the idea of design "any identifiable sign of divine action"--stripped
it of any empirical content.44 And toward those
who clung to such a tame and vacuous concept of design, even the most aggressive
Darwinist could afford to be indulgent.
"Every Trifling Detail"
Another important facet of the nineteenth-century debate is the strategy employed
to discredit design, and to redefine science in strictly naturalistic terms.
As the debate intensified, Darwin and his allies increasingly identified creation
with perpetual miracle. Historically, Paley and other proponents of design had
insisted on the reality of both primary and secondary causality at work in the
world. But the Darwinians ignored that history. Instead, they presented design
as the denial of all secondary causes. They portrayed a designed world as a
world at the mercy of divine caprice and arbitrary whim.
For example, in the Origin Darwin describes his opponents as holding
that each variety of finch on the Galapagos Islands sprang full-blown from the
Creator's hand. Moreover, he also describes his opponents as holding that the
islands' unusual flora and fauna were "created in the Galapagos Archipelago,
and nowhere else."45 Design was presented as the
belief that God had created each minor variety in its present location--giraffes
in Africa, tigers in Asia, and buffalo in America. Darwin referred to this as
the theory of "multiple centres of creation," and in the Origin he demolished
it.
Interestingly, Darwin concedes that, at the time, the idea of creation in situ
rested on empirical, not theological, grounds.46
For example, it appeared to be the only explanation for the existence of the
same species on both sides of the Atlantic Ocean. Surely no organism was capable
of migrating across thousands of miles of salt water. Be that as it may, Darwin
focused his argument on places such as the Galapagos Archipelago, where evidence
for migration was strong. Was it really plausible that each variety of finch
and tortoise had been specially created for each of the tiny islands, some of
which were, in Darwin's words, hardly more than "points of rock"? For myself,
he stated, "I disbelieve in . . . innumerable acts of creation."47
Much of the Origin is taken up with arguments for variability and migration.
The idea of separate creations would be more plausible, Darwin noted in his
journal, if each island had a completely unique set of plants and animals.
But since many of the organisms are variations on a common theme, it is difficult
to resist the conclusion that they descended from a single set of ancestral
species that originally migrated to the islands. This and other patterns of
geographical distribution, Darwin insists, are "utterly inexplicable on the
ordinary view of the independent creation of each species." He warns that anyone
who rejects the idea of migration, "rejects the vera causa of ordinary
generation with subsequent migration, and calls in the agency of a miracle."48
What do we say to all this? The views Darwin attributes to proponents of design
are so foreign today that we have to read our history books to learn about them.
No design theorist today denies the reality of variation or migration. The consensus
among even the strictest biblical creationists is that the Galapagos finches
were not separately created but represent variations within a single species.
For example, James Coppedge in Evolution: Possible or Impossible dismisses
them as "only minor adaptation within types, as would be expected in any design
of creation."49 Wayne Frair and Percival Davis
in A Case for Creation note that the finches "may serve as an example
of diversification" but "not evolution in the usual sense, because the changes
were relatively minor."50 Walter Lammerts, who
made detailed measurements of a large collection of Darwin's finches, notes
that they exhibit complete intergradation of bill and body size. He concludes
that the birds constitute a single species, "broken up into various island forms
as a result of chance arrangement of their original variability potential."51
Clearly, design does not require the rejection of either variability or migration.
In fact, historians have been hard put to explain why Darwin was so preoccupied
with a position that, already in his own day, naturalists had all but abandoned.
Some historians attribute it to Darwin's ignorance of the current state of the
debate; others think he was setting up a straw man. I suggest he was framing
a false choice between perpetual miracle and completely closed naturalistic
world. His argument ran like this: Either invoke direct divine action to explain
every phenomenon in biology ("call in the agency of a miracle"), or else admit
that every phenomenon can be explained by natural processes of "ordinary generation."
Darwin urged this false choice again and again. In The Descent of Man
he acknowledged that "our minds refuse to accept" an explanation of the universe
based on the idea of "blind chance." Yet the alternative, he went on, is to
believe that "every slight variation of structure,--the union of each pair in
marriage,--the dissemination of each seed,--and other such events, have all
been ordained for some special purpose."52 Darwin
wrote to Sir John Herschel: "One cannot look at this Universe with all living
productions & man without believing that all has been intelligently designed;
yet when I look to each individual organism, I can see no evidence of this.
For, I am not prepared to admit that God designed the feathers in the tail of
the rock-pigeon to vary in a highly peculiar manner in order that man might
select such variations & make a Fan-tail."53
In pressing the point, Darwin could not resist ridicule. In a book on the fertilization
of orchids, he described design proponents as those who view "every trifling
detail of structure as the result of the direct interposition of the Creator."54
In a letter to Asa Gray he wrote: "I cannot think that the world, as we see
it, is the result of chance; and yet I cannot look at each separate thing as
the result of Design." He confessed that he could not believe pigeon tail feathers
were led to vary "in order to gratify the caprice of a few men."55
He asked Lyell: Could he really think that the deity had intervened to cause
variations in domestic pigeons "solely to please man's silly fancies"?56
The argument became downright silly when Darwin challenged his friends to say
whether God had designed his nose. He wrote to Lyell asking whether he believed
that the shape of his nose "was ordained and 'guided by an intelligent cause'."57
In a similar vein, he asked Gray: "Do you believe that when a swallow snaps
up a gnat that God designed that that particular swallow should snap up that
particular gnat at that particular instant?"58
In these almost facetious comments Darwin was ignoring centuries of debate
among Christians over the balance between God's direct activity and the action
of created causes. As Anglican theologian E.L. Mascall writes, "The main tradition
of classical Christian philosophy, while it insisted upon the universal primary
causality of God in all the events of the world's history, maintained with
equal emphasis the reality and the authenticity of secondary causes."59
Scottish theologian Thomas Torrance sums up this balanced view by speaking of
the "contingent order" of creation. "Contingency" refers to the fact that the
creation is not autonomous. It is not self-originating or self-sustaining; it
was created by God and depends continually upon His power. On the other hand,
"order" refers to the fact that God does not work in the world by perpetual
miracle. He has set up a network of secondary causes that act in regular and
consistent patterns.60 As Christopher Kaiser points
out in his book Creation and the History of Science, attempts to conceptualize
this balance have carried on since the time of the church fathers--notably by
Basil of Caesarea in the fourth century.61 Darwin
ignored this rich history and slashed the Gordian knot by insisting that one
must choose either God or nature. Give any quarter to divine activity, he implied,
and the entire world becomes an arena of perpetual and arbitrary miracle. On
the other hand, allow that minor variation and diversification can be accounted
for by natural processes, and one must place all the world and all life solely
under the domain of natural law.
This false dichotomy continues to be useful to Darwinists today. Admit that
natural processes account for the diversification of finch beaks or peppered
moths or fruit flies, we are told, and one is logically committed to admitting
that the same processes are adequate to create birds and fruit flies in the
first place. Only recently has this strategy begun to wear thin, with biologists
recognizing that minor variation is not the means of producing major innovations.
Simply put, micro-evolution is not the mechanism for macro-evolution. Yet examples
of micro-evolution continue to be exhibited as the prime factual evidence supporting
naturalistic theories of evolution.
The Politics of Science
In considering how Darwin won the day, we must not ignore politics. The changes
sought by nineteenth-century Darwinists were not only intellectual but also
institutional. The older epistemology of science accommodated both religion
and science: It allowed theology to place limits on the ideas acceptable in
science. Once again, this was a balance rooted as far back as the church fathers.
The second-century apologists accepted as much as they could of the science
of their day (which was a product of Greek philosophy), but they insisted on
certain limits: For example, they rejected the idea that the universe is eternal
and instead insisted on an absolute beginning, on God's creation of the world
ex nihilo.62
But the new naturalistic epistemology promoted by the Darwinists was aggressively
autonomous. It demanded that science be completely independent of theology.
Gillespie writes: "The very existence of a rival science or of an alternative
mode of knowledge was intolerable to the positivist"; he was "intolerant of
all other claims to scientific knowledge. Anyone not of his tribe was a charlatan,
an imposter." As a result, these disagreements did not remain merely academic:
They precipitated a struggle for power over social institutions. As Gillespie
explains,
"It was not enough to drive out the old ideas. Their advocates had
to be driven out of the scientific community as well. . . . In order for
the world to be made safe for positive science, its practitioners had to
occupy the seats of power as well as win the war of ideas. Both were necessary
to the establishment of a new scientific orthodoxy."63
Many scientists are understandably uncomfortable with the idea that skill in
politics and public relations help a theory gain acceptance. They like to believe
that the dominant factor in the success of a theory is the objective evidence
in its favor. Yet sociologists of knowledge are right in stressing that science
is to some extent a social process, and that an advantage is gained by those
who are skillful at controlling the social process, at attracting supporters
while isolating opponents.
In hindsight, the strategies pursued by the nineteenth-century Darwinists are
clear. Before publishing the Origin, Darwin carefully cultivated a nucleus
of biologists who were prepared to support his work. These early converts then
followed basic political strategies: They presented a unified front in public;
they conceded minor points in order to make major points; they were willing
to accept as allies people who disagreed over the details; they minimized open
controversy that might alienate doubters and fence-sitters, while cultivating
younger scientists who were open to the new ideas. In this way, the Darwinians
gradually gained a majority. Their supporters were able to influence the educational
system as teachers. They took control of the editorial process at scientific
periodicals so that editors and referees became willing to accept papers from
a Darwinian viewpoint. The new journal Nature was founded at least in
part as a vehicle for spreading the Darwinian message. Darwin won the day in
part because his supporters were adept at employing PR tactics, and they simply
out-maneuvered their rivals.64
It would appear that latter-day design theorists have caught on. Today the
movement has capable leadership (such as that provided by Phillip Johnson);
it has launched a professional journal (Origins and Design), started
a fellowship program at the Discovery Institute, founded an honors program at
Biola, and is holding professional conferences (the Mere Creation Conference
in 1996). I suggest that we are well on our way to building our own institutions,
and there is surely reason to hope that we may one day turn the tide.
In closing, I would like to pose a sampling of questions that emerge from a
survey of the history of the evolution debate. Since the nineteenth century,
these have been among the most frequently raised objections to design, yet they
have not been adequately answered by design theorists:
An understanding of history. The nineteenth century marked the birth
of historical consciousness in every field, from philosophy to the sciences.
But the notion of design was essentially static, and as a result it was swept
away by theories that offered some account of the history of life. How do up-dated
versions of design get beyond a static view of life, and account for history?
Mind as cause. What exactly is meant in speaking of a mind or intelligence
acting in nature? What is primary causality? How is such a notion scientific?
Does such a notion introduce sheer "mystery" and "caprice," as Gillespie puts
it? One of Darwin's margin notes from 1838 reads as follows: "The explanation
of types of structure in classes--as resulting from the will of the deity,
to create animals on certain plans--is no explanation--it has not the character
of a physical law / & is therefore utterly useless--it foretells nothing
/ because we know nothing of the will of the Deity . . . . "65
Darwin is quite right: We cannot directly know the will of God. How then can
it be scientific to speak of divine intention and divine action in the world?
End of science?. Does design imply an end to scientific inquiry? Sir
Joseph Dalton Hooker said he embraced Darwinism--what he called the "newest
doctrines"--"not because they are the truest but because they do give you room
to reason and reflect." By contrast, the old doctrines of design "are so many
stops to further inquiry; if they are admitted as truths, why there is an end
of the whole matter, and it is no use hoping ever to get to any rational explanation
of origin or dispersion of species--so I hate them."66
Hooker's view is shared by many today: i.e., that to attribute something to
design is not to explain it at all. It is to throw in the towel, to halt inquiry,
no give up hope of any rational explanation. How do modern design theorists
answer this objection?
Does the concept of design have any empirical content?. In the Origin,
Darwin twits the design theorists of his day for allowing that some structures
result from secondary causes, while insisting that others are designed, but
offering no principle for distinguishing between the two. Why not just attribute
all of them to secondary causes? he asks. In his words: "Several eminent naturalists
have of late published their belief that a multitude of reputed species in each
genus are not real species; but that other species are real, that is, have been
independently created. This seems to me a strange conclusion to arrive at. They
admit that a multitude of forms, which till lately they themselves thought were
special creations . . . have been produced by variation, but they refuse to
extend the same view to other and very slightly different forms. Nevertheless
they do not pretend that they can define, or even conjecture, which are the
created forms of life, and which are those produced by secondary laws. They
admit variation as a vera causa in one case, they arbitrarily reject
it in another, without assigning any distinction in the two cases."67
If design theorists insist on the reality of both primary and secondary causality,
what principle do we offer for distinguishing between their effects?
The problem of evil. Darwin wrote there was just "too much misery in
the world" for him to believe in design: "I cannot persuade myself that a beneficent
and omnipotent God would have designedly created the Ichneumonidae with the
express intention of their feeding within the living bodies of Caterpillars,
or that a cat should play with mice."68 Other examples
were "the young cuckoo ejecting its foster-brother" and "ants making slaves."69
How do contemporary design theorists explain the presence of evil in a designed
world?
What philosophy of science does design theory entail?. Hull writes
that older theories of design rested on two pillars: a Baconian understanding
of induction, with its claim of guaranteeing absolute certainty, and an essentialist
metaphysic. James Moore in The Post-Darwinian Controversies echoes the
same theme, describing Christian anti-Darwinists as those who sought "ultimate
certainty through inductive inferences," with the corollary belief that the
world "contains a finite number of fixed natural 'kinds.'"70
Does the notion of design in fact require us to embrace these philosophical
positions?
