There’s a serious point in my playful invocation of Pilgrim’s Progress. Like many of the most complex human endeavors — parenting, farming, becoming a Christian — the life of a scientist is not just an “occupation,” something that occupies us for a while and might then be followed by something entirely different. Being a scientist is as much about being as doing, as much about a particular way of being formed as a person as it is a set of activities or even skills. Training in science is induction not so much into a particular worldview (though it includes absorbing plenty of the kind of cognitive presuppositions that that word suggests) as it is a kind of posture or stance toward the world, toward one’s work, and toward one’s fellow human beings, both scientists and non-scientists. And the life of a scientist is a journey, one freighted with ultimate concerns and laden with values. It is a journey into a set of virtues, the habits and dispositions that make one a person of a particular kind of character.

When we talk about faith and science, we tend to focus on the cognitive content of both endeavors, the truth claims and worldviews that animate these two crucial dimensions of modern human life. These are important matters, and I don’t at all mean to diminish them. At the same time, there are inevitable limits to what any pastor can do to constructively integrate the knowledge content of science — so vast and rapidly expanding that even scientists cannot pretend to be expert in anything but a tiny portion — with the content of Christian faith. But there is another way to approach faith and science which I believe might well be more within reach of most pastors, and more essential to their job description than being deeply literate in the latest scientific discoveries and theories — and that is simply to attend to, and prayerfully support and encourage, the scientific life itself as a vocation that can reflect the image of God and be a place for working out one’s own salvation.

So here is what I wish our pastors — and fellow Christians — knew about the life of a working scientist.

Delight and Wonder

If there is one personality characteristic of the vast majority of scientists I have met, it is delight. There is something about science that attracts people who are fascinated and thrilled by the world. To be sure, any given scientist is delighted by things that you and I may find odd or indeed incomprehensible — the intricacies of protein folding, the strata of Antarctic ice cores, or the properties of Lebesgue spaces (and no, I have no idea what that last phrase really means). But the specificity of their delights is one of delight’s secrets: like love, delight is always most potent when it is particular. It is certainly possible to find lawyers who are delighted by law (I have one friend who can go on at great length, with enthusiasm, about corporate bankruptcies), dairy farmers who are delighted by cows, or lumberjacks who are delighted by trees — but I dare say your chances are much better that when you meet a scientist you will find that they are delighted with the tiny part of the world they study day to day. (At least when they are not frustrated with it — which we’ll examine below.)

In many scientists, delight is matched by wonder — a sense of astonishment at the beautiful, ingenious complexity to be found in the world. This is not the “wonder” that comes from ignorance — “I wonder how a light bulb really works?” — but a wonder that comes from understanding. Indeed, as we progress further into humanity’s scientific era we have been able to disabuse ourselves of a mistaken early-modern notion: that the more the world became comprehensible, the less it would be wonderful. That turns out not to be true at all — ask a scientist. Wonder grows as understanding grows. Indeed, wonder only grows if understanding grows. If we replace our childhood awe of lightning with an explanation like, “It’s nothing but a transfer of voltage across a highly resistive material” (an example of what G. K. Chesterton wittily called “nothing-buttery”) perhaps the world will seem like a less wonderful place. But those who actually pursue knowledge of lightning — of electromagnetism or cloud formation or weather systems or climate — end up being more in awe of the world than they were as children. This is surely one of the remarkable features of our cosmos: the more we understand about it, the more we are in awe of its beautiful elegance and simplicity, and at the same time its humbling complexity.

To be sure, many if not most scientists do not see this wonderful world in the way that most Christians would hope for. For us, wonder is a stepping-stone to worship — ascribing our awe for the world to a Creator whose worth it reveals. For many scientists, wonder is less a stepping-stone than a substitute for worship. Yet they stop and wonder all the same.

Intellectual humility

I doubt that humility is among the first traits most people think of when they think of scientists. And indeed, some scientists (like some academics and intellectuals generally) exhibit a combination of confidence in their own intellect and limitations in their social skills that makes them seem abrasive if not arrogant. A few have made a public career of intellectual overreaching, not least in matters of science and faith. But in my experience (and certainly, let me stress, in the case of my own wife!) this is much more the exception than the rule. If intellectual humility is essentially a willingness to admit what you do not and cannot know, science cultivates humility like few other pursuits can — because in few other pursuits do you so often find out that you were wrong.

Even though we tell the story of science through its high points — the discoveries and confirmed theories that won Nobel Prizes and launched new eras in technology — the actual practice of science, for nearly every working scientist, involves far more failure than success. This is especially true for experimental science, the kind that requires the most direct interaction with recalcitrant reality. On most days, in most labs, the data do not add up, Matlab has an untraceable bug, the laser is on the fritz, and all the cultures have been contaminated when the undergraduate research assistant sneezed. And while each of these everyday setbacks requires immense amounts of patience and persistence to overcome, they are only the quotidian version of the perplexity that begins early in the study of science. Every scientist, in the process of their training, has had to repeatedly discover that their intuitions about the world are simply wrong, or at least incomplete. Even great scientists have come up against the sheer oddity and unpredictability of the world — Albert Einstein, for example, never fully accepted the uncertainty at the heart of quantum mechanics, something that is now universally accepted by physicists.

This regular confrontation with the limits of one’s own knowledge and skill is not to be taken for granted. The other divisions of the academy, the social sciences and the humanities, deal with matters of such variability and complexity that it is often difficult to say conclusively that anyone, or any theory, is entirely wrong. Marx’s and Freud’s grand theories may not seem nearly as plausible as they once were, but there are thousands of people following their lines of thought without losing the respect of their intellectual peers. But Ptolemaic cosmology or Lamarckian evolution now have, simply, no followers. They have been proved wrong beyond a reasonable doubt (although Lamarck’s ideas, interestingly, turn out to have a grain of truth in a way very different from what he expected). Who is likely to be more intellectually humble — someone who early in her training, and daily in her work, learns that her assumptions have been wrong, or someone who can always argue his way out of any intellectual predicament? It is perhaps no accident that “grade inflation,” in which undergraduates’ grades ratchet ever upwards in a nod to the consumer realities of the modern university, is much less pervasive in the sciences, where you can’t cajole your way into an A. The honest, and humbling, truth is that there is likely more intellectual humility in the average physics laboratory than in the average theology classroom.

Evidence from the Size of the Universe

We’ve already discussed the vastness of the universe earlier in this chapter. We noted that the most distant galaxies are over 10 billion light years away, indicating that the light left these galaxies over 10 billion years ago in order to reach us today. The straightforward interpretation of these data is that the universe must be at least 10 billion years old.

While some people have argued that perhaps these galaxies aren’t really that far away, all of the methods used to measure distance agree that galaxies are billions, not thousands, of light years away. Others have argued that perhaps the light moved much faster when it first left these galaxies, so that it could reach us in much less time than 10 billion years. But this idea conflicts with other data that we have. As described in Chapter 3, ample evidence supports the idea that physical processes such as quantum mechanics and electromagnetism function the same way in distant galaxies as they do on earth. Those physical processes depend on the speed of light and would look very different if the speed of light had changed. Instead, they look the same in distant galaxies as they do on earth, indicating that the speed of light has been constant over the history of the universe.

Evidence from the Moon and Planets

Studies of the Moon and planets also give evidence for great age. Geologists can use some of the same methods to measure the age of rocks on the Moon, Venus, and Mars as they use on Earth. That’s because the asteroid collisions, volcanoes, and erosion they observe on Earth also occur on the Moon and planets. Photos taken by spacecraft while orbiting Mars show channels and gullies on the planet’s surface. Similar channels on Earth are usually made by flowing water. Yet there is no liquid water on the surface of Mars right now.

What does this have to do with age? It is evidence that Mars was much different in the past than it is today. The atmosphere used to be much thicker and warmer, similar to Earth’s, but now it is much colder and thinner. This dramatic change in planet-wide climate took millions or billions of years. Thus the rocks testify that the planet Mars must be at least this old.

Evidence from the Orbits of Asteroids

The orbits of asteroids also show evidence of a long history. When an asteroid is discovered, its path through the sky shows its orbit around the Sun. Once astronomers know the orbit of an asteroid they can calculate its orbit in the past and into the future to see whether it will hit the earth. By calculating the orbits backward, astronomers have found several asteroids that converged at the same location several million years ago. Apparently two larger asteroids collided at this spot and shattered into the smaller asteroids we see today. If God had created asteroids just a few thousand years ago, why would he have put them in orbits that suggest a collision several million years ago? The evidence clearly points to a long history for asteroids.

Evidence from Meteorites

Radiometric dating is used to study rocks on Earth as well as rocks from elsewhere in the solar system. Studies have been done on the rocks that astronauts brought back from the Moon and on asteroids that have fallen to Earth. As with Earth rocks, scientists use multiple radioactive isotopes to cross-check age measurements. At least three different isotopes have been used to measure the age of Moon rocks, and at least five different radioactive isotopes have been used to measure the age of meteorites. The results all agree: the oldest Moon rocks and asteroids are 4.6 billion years old. This is our best measure of the age of the solar system as a whole. The universe itself must be at least this old.

Evidence from Star Clusters

Another important measure of age in the universe comes from star clusters. Because all stars in a star cluster form in the same nebula at about the same time, they all have about the same “birthday.” But they don’t all have the same lifespan. High-mass stars burn bright and fast like a “flash in the pan,” while low-mass stars burn slowly and steadily. Consider how this will look in a star cluster. A cluster starts with many stars with the same birthday but of all different masses. Over time the high-mass stars die off first, leaving behind the low-mass stars. This means that if many high-mass stars are present, the cluster must be young because they haven’t burned out yet. If most of the stars are low-mass, the cluster must be old. Careful studies of star clusters show that some clusters are younger and some are older, with the oldest ones having an age of about 12 billion years.

Multiple Lines of Evidence

The most distant galaxies, the planets and asteroids of our own solar system, and the oldest star clusters all are several billion years old. Astronomers have many different methods for measuring the age of various objects, and they all support ages of billions of years, not thousands. Even if the assumptions of one or two methods were faulty, it is highly unlikely that all of the methods would be affected. Like the geologists in the 1700s, astronomers today have found multiple lines of evidence against a young earth and young universe.

It may seem as though we are once again describing a conflict between science and theology. Scientific results that indicate great age do conflict with the Young-Earth Interpretation of Genesis 1 discussed in chapter 5. But remember that in chapters 5 and 6 we presented many other interpretations of Genesis 1; several of these are not in conflict with the great age found in the book of nature. In chapter 6 we also explained why we believe that the best biblical scholarship, quite independent of modern science, indicates that Genesis 1 was never meant to convey scientific information to the original audience. Its intent for the first listeners, and for us, is to teach the who and why of creation, not the how and when. Taken in this context, there is no conflict between Genesis 1 and the astronomical evidence for great age.

"Anyone approaching the Resurrection accounts in the belief that he knows what rising from the dead means will inevitably misunderstand those accounts and will then dismiss them as meaningless" (p. 243).

In fact, if Jesus' Resurrection were "merely" coming back to life in any way that we might comprehend, then it would be of little significance.

"Now it must be acknowledged that if in Jesus' Resurrection we were dealing simply with the miracle of a resuscitated corpse, it would ultimately be of no concern to us" (p. 243).

So what then does Resurrection mean? For Benedict it represents a new dimension of reality breaking through into human experience. It is not a violation of the old; it is the manifestation of something new.

"Jesus had not returned to a normal human life in this world like Lazarus and the others whom Jesus raised from the dead. He has entered upon a different life, a new life -- he has entered the vast breadth of God himself..." (p. 244).

Because it is something entirely new, it cannot represent a violation of natural law as understood by science.

"Naturally there can be no contradiction of clear scientific data. The Resurrection accounts certainly speak of something outside our world of experience. They speak of something new, something unprecedented -- a new dimension of reality that is revealed. What already exists is not called into question. Rather we are told that there is a further dimension, beyond what was previously known. Does that contradict science? Can there really only ever be what there has always been? Can there not be something unexpected, something unimaginable, something new? If there really is a God, is he not able to create a new dimension of human existence, a new dimension of reality altogether?" (p. 246-7)

Thus, in this view, Resurrection (as with all true miracles) is not contrary to science, but an indicator that science does not (yet?) describe the full expanse of reality. Indeed, some may argue that science itself contains similar "indicators." The 11 (or so) dimensional universe required by some versions of string theory, the multiverse theory of the universe where ours is but one of an infinite array of universes with variable physical laws, quantum entanglements, "spooky" action at a distance, the mysterious emergence of consciousness from inorganic matter -- all push the limits of human reason and imagination, suggesting to some that reality may be far more complex than the human mind can grasp.

For a moment, let us entertain the possibility that Resurrection is as Benedict interprets it: not a violation of natural law but an indicator of something beyond our scientific understanding of the universe. This has interesting implications for understanding how believers and skeptics approach the issue. If Resurrection does not violate science, then science does not necessarily constitute an impediment to accepting the reality of Resurrection. If the difference between the skeptic and believer is not science, then is it just a matter of imagination? The believer imagines greater possibilities for the universe than the non-believer. While this is possible, it seems questionable. To my knowledge, no research has found differences in imaginative abilities between religious and non-religious people. Moreover, contrarian examples easily come to mind: Isaac Asimov was an atheist but hardly lacking in imagination when it came to science fiction. I tend to think that both believers and non-believers can imagine (with varying degrees of effort, I'm sure) the new possibilities implied by Resurrection.

Thus, if it is neither imagination nor science that prompts skepticism about Resurrection, then what is left? I suggest that it comes down to a question of authority: At what point does one allow imaginative possibilities to have authority over how one lives? To the believer, Resurrection has an authority that science fiction does not. Resurrection is not thought-provoking entertainment. It requires far more than just imagining greater possibilities for the universe. It requires a change of life, here and now. Unlike the microscopic hidden dimensions of string theory, the new dimension implied by Resurrection has "broken though" into everyday reality and demands a response -- even if that response is to actively ignore it.

Now, what convinces the believer that Resurrection merits such authority when other imaginative possibilities such as extraterrestrial life or time-travel do not? The answer here appears to be historical commitment. There's no record of people committing themselves to the point of martyrdom to other imaginative possibilities as they have to Resurrection. The earliest example of such commitment being found, of course, in the dramatic post-crucifixion turn-around of the Apostles. Such an astounding change of heart, followed by an unwavering commitment capable of altering human history demands a categorically unique explanation: Resurrection.

The believer's argument, however, remains unconvincing to the skeptic. However impressive they might be, a change of heart and steadfast commitment do not necessarily add up to a new dimension of reality. Extraordinary claims require extraordinary evidence. Fair enough. So a key question regarding the interpretation of Resurrection is this: Is the post-crucifixion history of Christianity extraordinary? Does it compel the dispassionate observer to concede that a categorically unique event could plausibly be its best explanation?

It ought to be upon questions such as those above that skeptics and believers respectfully engage one another, rather than the simplistic and often acrimonious sloganeering that has increasingly become the norm.

Belief in God in an Age of Science

Introducing John Polkinghorne

An Englishman of Cornish descent, John Polkinghorne was born in 1930 in the coastal town of Weston-super-Mare, southwest of Bristol in North Somerset. Although his parents had three children, an older sister died in infancy and his older brother, who served in the RAF Coastal Command during World War II, died when his plane was lost over the North Atlantic on a stormy night in 1942. Effectively an only child from that point on, his family nurtured him in their Christian faith, leading him to say a few years ago, “I cannot recall a time when I was not in some real way a member of the worshipping and believing community of the Church.”  (From Physicist to Priest, p. 7)

At the same time, his gift for mathematics did not go unnoticed, resulting in several years of study at Trinity College, Cambridge (where Isaac Newton had lived and worked in the seventeenth century). As an undergraduate, Polkinghorne studied applied math rather than pure math, a typical choice for someone interested in physics. There, he formed a close friendship with a classmate, Michael Atiyah, who would be best man at his marriage in 1955 to another mathematics student, the late Ruth (Martin) Polkinghorne. Later knighted, Sir Michael was President of the Royal Society in the early 1990s, the same period when Polkinghorne was president of Queen’s College, Cambridge.

​Sir Michael Atiyah (Source)

Polkinghorne was particularly inspired by the course in quantum physics taught by Paul Dirac, whom he has described as “undoubtedly the greatest British theoretical physicist of the twentieth century,” an opinion with which it is hard to disagree. For Polkinghorne, Dirac’s lectures were simply unforgettable: “so profound was the material, and so closely structured was the argument, that one was carried along enthralled by the experience.” (From Physicist to Priest, p. 26)

Paul Dirac (Source)

Remaining at Cambridge for graduate study, Polkinghorne worked under the Pakistani physicist, Abdus Salam, who later became the first Islamic scientist to win the Nobel Prize, which he shared with Americans Sheldon Glashow and Steven Weinberg for contributions to unifying the electromagnetic force and the weak nuclear force. Then he did postdoctoral work at Caltech with Murray Gell-Mann, another future Nobel laureate for his work on quark theory, and attended the famous lectures by yet another future Nobel laureate, the late Richard Feynman.

After Caltech, Polkinghorne taught briefly at Edinburgh before returning to Cambridge, where he was soon elected to a new professorship in mathematical physics. Quantum mechanics (QM) is his specialty; his writings on both QM and its interaction with theological ideas are numerous. His book, The Quantum World, has sold more than 100,000 copies, and when Oxford University Press wanted a book on this topic for their highly successful series, “A Very Short Introduction,” it was Polkinghorne who wrote it. His former students include Nobel laureate Brian Josephson, “the most precociously brilliant undergraduate that I ever taught,” and Martin Rees, who was until recently President of the Royal Society.

Although Polkinghorne has never won a Nobel Prize, in 1974 he was elected Fellow of the Royal Society, the highest honor in British science. Three years later, at the top of his scientific career at age 46, he astonished his colleagues by announcing a decision to pursue ordination as an Anglican priest; two years later, he resigned his chair at Cambridge to enter seminary. Partly, he felt played out. As a former physics student myself, I do not find his diagnosis hard to accept: “In mathematically based subjects you do not get better as you get older. Somehow one needs mental agility more than accumulated experience, and it becomes progressively harder for an old dog to learn new tricks. It is unlikely that most people do their best work before they are 25, but most do before they are 45.” Or, to put it more succinctly, “I simply felt that I had done my little bit for particle theory and the time had come to do something else.” (From Physicist to Priest, p. 71)

Nevertheless, he also felt a genuine call to the ministry, for “Christianity has always been central to my life” and ‘becoming a minister of word and sacrament would be a privileged vocation that held out the possibility of deep satisfaction.” (From Physicist to Priest, p. 73) After seminary, Polkinghorne served as a parish priest for many years and later as canon theologian of Liverpool Cathedral. He was knighted in 1997—although, as an ordained minister, he declines to use the title, “Sir John Polkinghorne”—and was awarded the Templeton Prize in 2002. It has been altogether a life well lived for the kingdom of God.

Looking Ahead

I’ll return in about two weeks with a summary of Polkinghorne’s basic attitudes toward science and religion, which (in his view) have a “cousinly” relationship. In the meantime, readers are invited to read Zeeya Merali’s essay, “The Priest-Physicist Who Would Marry Science to Religion,” from the March 2011 issue of Discover magazine, and “An interview with John Polkinghorne,” by philosopher Paul Fitzgerald.

One of the more outspoken proponents of this view is Sam Harris, a leading figure among the New Atheists, and a fierce antitheist. Harris has written a book and given talks on the idea that morality—broadly, the act of discerning good from bad—can be derived from science.

On the face of it, this seems strange, since the scientific consensus, especially in evolutionary biology, has always been that nature is morally neutral. We know, as scientists, that sharks are not “bad” any more than dolphins are “good.” The true evolutionary view (I always thought) was that fitness is related to success, not goodness.

The problem is that as human beings, we know that goodness exists, so it must be accounted for, and if one is a staunch believer in scientism, it must be accounted for scientifically. In some situations, this accounting seems to be possible. There is a large literature on kin selection as the basis for some kinds of altruism, and Dawkins has made the case that what he calls “misfiring of genes” for kin altruism are responsible for human goodness.

Harris claims that moral values can be based on scientific principles, and that no kind of cultural context, especially faith-based context, is necessary for humans to have a code of morals. He bases this argument on the idea that moral values are based on facts, and that these facts can be tested for their truthfulness. To some extent, this is an old idea. Murder, adultery, theft and lying—some of the best-recognized universal moral prohibitions, all tend to destabilize the coherence of social groups and would therefore be selected against in all societies.

But Harris goes much further, using arguments and examples that are anything but scientific. Since Harris is a leader of the antitheistic movement, and is interested in finding examples of religious practices that he believes can be scientifically proven to be immoral. He cites the abusive treatment of women in Islamic societies as a main example, and he mentions corporal punishment of children as a slap at Christianity.

So how does Harris prove scientifically that forcing women to cover their bodies, and hitting school children with rulers are morally wrong? He doesn’t. Here is what he actually says:

But we can ask the obvious question: Is it a good idea, generally speaking, to subject children to pain and violence and public humiliation as a way of encouraging healthy emotional development and good behavior? Is there any doubt that this question has an answer, and that it matters?

Harris clearly believes the answer to that question is no, and I agree with him. But where is the science here? Has he data to show that children who were subjected to corporal punishment had worse emotional development and behavior than children who did not undergo such punishment? No. He has no such data, and in fact while he considers the wrongness of corporal punishment to be an obvious fact, there are millions of people who consider it to be just the reverse. There is no science here; there is simply a basic underlying moral idea, which Harris shares with others.

Harris touts the evils of Islamic fundamentalism as morally indefensible from a scientific point of view. But what kind of fact is it to say that making women cover their bodies is wrong, other than the “fact” that Harris thinks it is? Is there a science for determining the optimal way to treat women? If there is, it isn’t mentioned by Harris. 

While it may seem obvious that the oppression of women is morally wrong, proving scientifically that its disadvantageous to the thriving of our species is more tricky. In fact, the moral values of Harris, which are typical Western Judeo-Christian values, are largely counter-evolutionary. What we see when we look at history or sociology, is a background of true selection-positive behavior—indiscriminate killing of enemies, sexual aggression, concentration of power in a dominant faction—on which has been superimposed a moral code, followed and enforced despite its anti-evolutionary tendency. The real question to ask is: How is it that humans obey any of these moral codes that do not help them survive as individuals or as members of a culture?

In truth, there is no science at all behind Harris’s grand claim of factual moral values, (beyond such obvious things as it isn’t a good idea to add cholera germs to the water supply). He even admits this by stating:

Now the irony, from my perspective, is that the only people who seem to generally agree with me and who think that there are right and wrong answers to moral questions are religious demagogues of one form or another.

Of course that is correct, because both Harris, and the people whom he calls “religious demagogues,” have formulated moral codes that they hold to in the absence of any “scientific” data. 

The argument that morality is outside the scope of science is not a hard one to make, but it isn’t only morality that must be excluded from the domain of science. The more important argument is that very few of the ideas of evolutionism are based on anything remotely scientific. This is because the evolutionism paradigm includes many distortions of Darwin’s great theory, and too many of these distortions have become accepted by an antitheistic academic culture without proper rigorous analysis. 

Like Steven Jay Gould, I see no evidence that the biological mechanisms of evolution by natural selection can be extrapolated beyond the bounds of biology. Gould devotes several chapters in The Richness of Life to attacking the “adaptationist paradigm,” which is a central part of evolutionism. In responding to Daniel Dennet’s assertion that adaptation and selection explain just about everything, Gould says:

The fallacy of Dennet’s argument undermines his other imperialist hope that the universal acid of natural selection might reduce human cultural change to the Darwinian algorithm as well … The chief strategy proposed by evolutionary psychologists for identifying adaptation is untestable and therefore unscientific.

Cunningham has also explored this issue in Darwin’s Pious Idea. Social Darwinism, eugenics, evolutionary psychology, sociobiology, mimetics and other nonbiological applications of Darwin’s theory are not rationally consistent with the fundamental properties of evolution by natural selection. 

Evolutionism has been used to “explain” all sorts of dynamics in culture, using evolutionary concepts. But, while the evolution of devices that play music (as an example) might bear a resemblance to the evolution of carnivores, it is a superficial resemblance. Devices do not replicate themselves, so they cannot be the target of selection. 

Scientism is a failed philosophical approach to the pursuit of universal truth. Its failure should be evident especially to scientists who, more than most, understand the limits of their fields of study, as well as the enormous effort it takes to wrest nuggets of pure truth from nature. We must, as previous generations of enlightened thinkers have done, admit that issues of morality, beauty, thought, love, art, and culture are not approachable by scientific methodology or tools, or we risk losing a huge part of our human endowment of special (if not divine) genius.

Morality, or more strictly our belief in morality, is merely an adaptation put in place to further our reproductive end.

Important scientific theories invite philosophical and theological reflection. Dawkins, Ruse, and Wilson, have described their conclusions. But scientific theories are often compatible with multiple philosophical and religious interpretations. For example, Newton's laws of motion and gravity allow several competing theistic and atheistic interpretations.

To avoid Ruse and Wilson's philosophical conclusion, we need not dispute their scientific hypothesis about how morality evolved. We need only dispute their philosophical extrapolation as to why morality exists. Even if we restrict ourselves to an atheistic worldview, this extrapolation is questionable. Donald MacKay (1965) would call this an example of "the fallacy of nothing but-tery". This is the assertion that a description of something at one level renders other levels of description meaningless. From our everyday experience, we know that a successful description on one level does not invalidate other levels of description. For example. one might assert that a Shakespeare sonnet is "nothing but" ink blots on a page (MacKay 1965). True, one way to describe a sonnet is to precisely specify the page coordinates of every ink blot. This description is valid and complete on its own level; however, one could also analyze the sonnet linguistically, emotionally, socially, historically, and on other levels. If one is programming an inkjet printer, the most important description is in terms of ink blot coordinates. For almost every other purpose in life, however, that is an unimportant level of description. In the same way, a complete evolutionary description of the existence of morality does not necessarily invalidate the truth, utility, or significance of other levels of description of morality.

If we do not restrict ourselves to atheism and instead allow for the existence of a creator, the extrapolation from how morality evolved to why morality exists fails further. Consider an analogy. Suppose an inventor builds a robot which could do a variety of useful things-- mow the lawn, clean the house, grade homework, write book chapters, and so on. One thing this robot can do, given a complete set of spare parts, is build a replica of itself. Whenever the inventor needs another robot, she gives one robot a set of spare parts and has it build a replica of itself. Amongst all the software subroutines within this robot, there is a set of subroutines that govern the robot's self-replication, including the replication of those self-replication subroutines. Would it be correct to say that the purpose of the robot's existence is merely to reproduce those particular self-replication subroutines? Do all of the other software and hardware of the robot--which allow it to mow the lawn, and so on-- merely further the reproductive ends of those self-replication subroutines? At one level, the robot's hardware and software do serve to reproduce those self-replication software routines. At another level of analysis, however, those self-replication software routines serve the robot to produce more copies of itself. At still another level, those self-replication software routines serve the robot's creator. The creator of the robot should get the last world as to which of those levels of description is most important.

In humans, does morality exist to further the reproduction of certain genes, or do those genes exist in order to allow for the production of new human beings who can behave morally? If human beings have a creator, the creator gets the final word on the question of purpose. The mechanism which the creator used to make those genes-- whether de novo or via evolution-- is secondary. The creator's purpose in creating those genes decides the issue.

For many people, science invites awe and religion invites insight. When awe and insight engage, science-and-religion happens.

If we can understand the experiences of the people who work every day in the lab, our dialogues concerning science and religion will be far more fruitful than they would be otherwise. I realised this when someone recently asked me what the highlights had been during my own time as a biologist. I explained that what I appreciated most was the privilege of experiencing science first-hand. My horizons have been expanded, and I now have a better understanding of how vast and complex the natural world is. Appreciating the grandeur of the universe seems to be a universal for humankind, including research scientists in their own peculiar way. Everyone has something to add to a conversation about experiences of awe, as I discovered when I blogged on it recently and invited a number of friends and former colleagues to comment. This sense of awe is a perfect starting point for discussions of science and theology.

Life in the Laboratory

I had always loved finding out how things work, and that was one of the reasons why I chose biology, but actually working ‘at the coal face’ was an eye opener. Living organisms are extremely complicated, so one has to choose only a tiny part of an organism to study: maybe a single gene or a feature of its behaviour. It can take years to understand just one aspect of that tiny part in enough depth to be able to publish an academic paper about it. Experienced scientists describe how the sum of human knowledge is so small as to be insignificant in comparison to what is out there, and I can now appreciate that a little bit. I can also appreciate what fun it is to survey all that un-knowledge, grab a bit of it and try to figure it out.

In the world outside of the lab we hear the headlines about new discoveries, but we have no idea what is behind that one-liner. In reality the story of a discovery in biology may well have started with a graduate student who nervously began their new project, a more experienced scientist who sacrificed precious time to train and supervise them, and the lab head who looked over the data every now and then. There would have been long days and nights in the lab and many false turns before the first piece of promising data emerged. No doubt there were anxious re-runs of experiments to confirm the results, and moments of elation as things started to make sense. The work would have been presented to critical colleagues who suggested further experiments. Frustrating months would have been spent generating the final pieces of data, weeks bent over a computer writing a dense and meticulously referenced paper, submission to a journal, the referees’ criticisms, a few more experiments, resubmission, and a long wait. Finally the paper was accepted and the whole research group joined in the celebration. And this is only the simplest possible version of events – the process of producing successful research can involve large numbers of people over several years, international collaborations, promising leads that go stale, and surprising results from unexpected places.

The ‘real world’ of science is a million miles away from the debates on science and religion that happen in churches, universities and schools throughout the world. Behind every piece of research is a team of people representing different faiths and belief systems, a variety of cultures, social backgrounds and personality types. Perhaps scientists are all a little crazy (who would put in the hours otherwise?), but they’re definitely all motivated in different ways.

The factors that attract people to science are many, though inspiring and supportive parents or teachers can play a large part. The reasons why individuals decide to stick with research, despite all the demands and uncertainties that a life in science brings, are interesting and at times surprising. There is the fascination of understanding the natural world, the value of original research, the prospect of new technologies further down the line, and the privilege of making new discoveries. There is also the opportunity to ask new questions, and the immense satisfaction when things come together and begin to make sense. So far, so predictable. More unexpected drivers are the enjoyable process of tinkering with experimental systems, the opportunity to exercise great creativity, the beauty of scientific data, and a feeling of immense awe when one gets a rare insight into the way the world operates. The rewards for doing science range from the utilitarian to the downright spiritual.

Awe in Science

Awe is an important part of the experience of science – one could almost say it’s a universal. When a scientist feels awe it is usually in response to something complex, precise, ordered, powerful or beautiful. There is an element of unexpectedness and delight, maybe even respect, fear or reverence. Awe always involves the need for some sort of mental adjustment or accommodation: we need to make room in our internal map of the world for this new and amazing experience. The physicist Werner Heisenberg vividly described this process of taking on board a startling new concept when he wrote of his discovery of atomic energy levels:

“In the first moment I was deeply frightened. I had the feeling that, through the surface of atomic phenomena, I was looking at a deeply lying bottom of remarkable internal beauty. I felt almost giddy at the thought that I had now to probe this wealth of mathematical structures that nature down there had spread before me.”

Moments of awe are the rare high-points in science, both rationally and emotionally. Finally something is understood. That understanding and the new possibilities it opens up are wonderful, and the story is told and retold. Scientists, as you might expect, respond scientifically, with new questions and investigations. But they also respond in other ways depending on their personalities: aesthetically, using visual representations of the data in different ways; philosophically, as they discuss the ethical implications of the research or the surprising intelligibility of the universe; or spiritually, as they try to make sense of those feelings of awe and wonder at the immensity and beauty of the world.

When Elaine Howard Ecklund carried out some research into the beliefs of scientists in elite US universities, she discovered a surprising fact: 20% of the people that she and her research team spoke to were not members of any religious group, but considered themselves spiritual. For some of these scientists the experience of beauty, awe and wonder in their work led them to believe that there is something beyond science – one could perhaps call it ‘transcendent’ – an experience that motivated some of them in their research, their teaching, and their lives outside of the lab. I remember having a conversation with a colleague who had experienced something along these lines, so I’m not surprised to hear that many others feel the same.

According to the scientist-theologian Alister McGrath, experiences of the transcendent might involve a sense of the ‘numinous’ – a feeling that something ‘other’ might be behind what one is seeing. Or perhaps someone might encounter a deep truth about the unity of reality that strikes them in a particular way. Perhaps more common would be a moment of unexpected clarity – what some might call an epiphany – where suddenly things make sense. Experiences that might be called ‘transcendent’ are rare, but they leave a lasting impression.

The language used by many scientists when they describe the process of discovery is of a reality that was always there. Perhaps it’s not surprising that scientists are ‘realists’; they think that there is a real world outside of ourselves that waits to be discovered. Science does not answer the ultimate questions about the universe, but scientists are human beings so we just ask those questions anyway – sometimes looking for answers in unexpected places.

Spirituality in Science

At the beginning of this piece I mentioned my growing realisation of the size of the scientist’s task. The seeming inexhaustibility of the created order can be overwhelming, but many see this as something positive. There is so much more to explore. As the Jesuit philosopher Enrico Cantore has said, the mystery of the universe lies not in ignorance, but in dazzling intelligibility. Where do these thoughts of transcendence, reality and mystery lead? For Einstein, they were a religion. A Mind other than our own was somehow responsible for this world that we can make sense of using the language of mathematics. For others, the reality we see in the world leads to ideals that transcend differences of language, culture and religion.

We search for meaning, and we long for more. CS Lewis famously describes the world we live in as a pale reflection of the one to come.³ For those who already believe in God, what we see in science makes sense. We live in a world that operates according to principles that we can understand and describe mathematically. We can utilize what we find for good or evil (and everything in between), and what we discover is both beautiful and awe-inspiring. William Whewell, the nineteenth-century polymath and Master of Trinity College, Cambridge, said that ‘We must find the right thread on which to string the pearls of our observations, so that they disclose their true pattern.’

For me, what we see in science is not evidence for God, but works well as a thought experiment. What would you expect if God existed? In the context of faith, science increases my sense of awe and wonder and helps me to worship God in a more genuine way. The Christian songwriter Matt Redman said that we sometimes ‘take the extraordinary revelation of God and somehow manage to make Him sound completely ordinary’. Science has the power to expand our horizons and helps us to see how great God is. The dazzling intelligibility of the world increases our humility, as we realise that because we ourselves are a fragile and finite part of the universe, we will never be able to fully grasp what we see in an objective intellectual way.⁴ Our response to what we see in the world is rational, emotional and active: worship as well as systematic theology.

The highest mountain peaks and the deepest canyon depths are just tiny echoes of His proclaimed greatness. And the brightest stars above, only the faintest emblems of the full measure of His glory.⁵

Today, as I write, I am no longer in the desert of southern California, nor in the beech-maple forest of New Hampshire, but on a glacial drumlin in Waubesa Wetlands—a large marsh four miles south of Madison, Wisconsin. Here Ruth and I have our home, and here I study creatures whose watery habitats my neighbors and I have worked to save from eventual destruction. While my desert study site now is covered by a city where people live alone in the land—absent the desert creatures—my wetland study site remains occupied by all kinds of native plants and animals. Embracing it is the Town of Dunn, whose land stewardship plan helps people understand, serve, and maintain this and the other ecosystems. Our town stewardship plan encourages restoration of the landscape, protects agricultural lands, and strives to transmit an intergenerational heritage of secure and wholesome homes, livelihoods, and habitats for the animals, plants, and people that live here. We live largely in harmony and accord.

House-building on slabs poured onto desert sands first alerted me to the question of praxis, the third point on the napkin. But it was later, in my work as organizer of the Waubesa Wetlands Scientific and Agricultural Preserve, and as supervisor and later as chair of the Town of Dunn, that I came to realize that science and ethics do no earthly good unless put into practice. In serving my town, I came to apply what I had learned in the desert: praxis uninformed by science and ethics usually creates more problems than are solved.

“How do you put it all together?” those students in New Hampshire wanted to know. For me, it was building a framework for stewardship that simultaneously considered the questions “How does the world work?” “What is right?” and “What then must we do?” This science-ethics-praxis triad is a framework for living, for learning, for teaching, and most importantly for acting. It is a framework for stewardship.

In order to live and act rightly in the world, we need to know how the world works. We need to know how the systems that sustain us work, and how we interact with them. Without such knowledge we could drown in a flash flood, have our homes undercut by desert winds, cross the street in the path of an oncoming car, or get sick from consuming foods with toxic ingredients. As human beings develop more and more of the world, and as the reach of human actions extends regionally and globally, our knowledge must increase accordingly. This knowledge is not limited to what we acquire from a formal education; it also includes the knowledge we gain from family and friends, and from experience and experiment. In order to live and act rightly in the world, we need to know how the world works.

In order to live and act rightly in the world, we need to know what we ought to do. A century ago, this question was addressed in many colleges across America in a course for graduating seniors on moral philosophy. The purpose of this course was to convict students that they should apply their knowledge for the pursuit of good instead of pursuing self at others’ expense. At my university, this aspect of college education is expressed in a quotation from Abraham Lincoln carved in stone on a bench behind Lincoln’s statue at the top of Bascom Hill: “Let us have faith that right makes might, and in that faith, dare to do our duty.” The question “What is right?” is represented by the ethics corner of our triad. Moving directly from the Science corner to the praxis corner, or from the ethics corner to the praxis corner, proves problematic, even disastrous. Consider the result of going from knowledge of nuclear fission (science) directly to producing and dropping an atomic bomb (praxis), or moving from the belief that death is bad (ethics) to removing dead wood from forests (praxis); both are examples of these disastrous shortcuts.

But knowing the science and observing the ethics of this stewardship framework does absolutely no good if it is not put into practice—placed into service. By themselves, the very best science and the most substantial ethics are no substitutes for action. We need to act appropriately and deliberately in the light of scientific and ethical knowledge. Praxis by itself, without being grounded in science and ethics, results in mere activism—activism that is unlikely to do good and that may produce harm. All three corners of the triad are essential—but not by themselves. Taken together and working interactively, they provide a framework for stewardship.

But will these three operate in dynamic interaction? Will they interact in ways that preserve and achieve the integrity of human life and the environment? The answer depends on what we know and understand about ourselves and the world (science), what we believe we should do (ethics), and what we in fact do, and how we respond to our successes and failures (praxis). It depends on our will, our motivation, our determination, and our dedication to strive for a harmonious world of creatures before their Creator. What might make us strive for such a world?

Part 3 explores the challenge of translating ideals into concrete actions.

A careful study of this chapter is important because it gives us a beautiful picture of the proper relationships we should have with God, the natural world, and each other. Numerous posts could be written on each of these relationships, but in this post I’d like to focus on how Genesis 2 describes our relationship to the rest of creation. These relationships are given deeper significance when we recognize that the garden is being described as a temple-like “sacred space,” not just an ordinary garden. There are numerous clues in the passage that this is the case. John Walton writes that the Garden/temple parallels “are givens that are simply assumed by the author and audience” ¹ of Genesis, but we completely miss them if we take fail to read the text the way the ancient author and audience would have.

Temples and Gardens

In the Ancient Near East (ANE), all sacred space was conceived of as something like a temple; it was a place where humans would serve God and experience their closest access to Him. Thus in ANE cultures, a temple complex was seen as being the apex and a microcosm of creation and the earthly abode of the god(s). Descriptions of temples often pictured a river flowing from under the temple and flowing out through an adjacent garden, symbolizing the fertile extravagance of the divine provision. A temple garden would be no mere backyard vegetable patch, but rather an elaborate, beautifully landscaped botanical park.

The same temple/river picture can be seen in the description of the eschatological temple in Ezekiel (ch. 47) and Revelation (chs. 21-22, where the final temple is God Himself). Sound familiar? In Genesis 2 we also have a river flowing “from Eden [‘Abundance’] to water the garden” (v. 10).² Not only is the Garden filled with “every beautiful tree with edible fruit” (v. 9), but the area itself is rich with gold, resins, and gemstones (sometimes translated “bdellium and onyx”), the same materials later used to decorate Israel’s tabernacle, temple, and priestly garments. Furthermore, many scholars are convinced that the design of temple’s Menorah (candlestick) deliberately echoes the Garden’s Tree of Life, and some also think that the Ark of the Covenant in the temple parallels the Tree of the Knowledge of Good and Evil.³

Made for Sacred Service

As inhabitants of this temple-garden, it comes as no surprise that Adam and Eve enjoyed a special closeness to God’s presence (Gen. 3:8 pictures God taking an evening walk through the Garden). But as inhabitants of the Garden, they had special responsibilities as well; they were told “to farm it and take care of it” (v. 15). The two Hebrew words used here have a broader range of meaning than their English translations suggest. As John Walton writes, the broader meaning of the word here translated “to farm” (particularly when used in a sacred context) “is often connected to religious service deemed as worship (e.g., Ex. 3:12) or of priestly functionaries serving in the temple precinct (e.g., Num. 3:7-10).” ⁴

The usage in Genesis 2 seems to have two layers of meaning: “farm/cultivate the Garden” (since it is an agricultural space) and “serve/worship God” (since the Garden is also a sacred space). The dual meanings are as intertwined in Hebrew grammar as they are intended to be in practice. The second Hebrew word (translated “take care of”) has a deeper religious meaning as well. The word can refer to protecting farmland from external threats, but in a danger-free sacred space like the Garden, the word more generally refers to “performing duties on the [temple] grounds,” that is, to “sacred service.”⁵

Walton therefore translates these two Hebrew words as “serve and preserve.” These same words appear again together several times in Numbers to describe the priest’s duties in the temple. Because of all this, Gordon Wenham describes Adam as “perhaps…an archetypal Levite” with a “quasi-priestly” role in the garden.⁸ Eve was created as Adam’s companion and “helper” in his work, a word which nowhere in the OT refers to a subordinate assistant, but rather to one who is at least equal to the one being helped.⁹

Genesis 2 should banish from our minds any idea that creation care is somehow “secular” work for a Christian, or that it is not even our responsibility. This was the first task given to humanity, to serve and worship God by cultivating and protecting the natural world. The centrality of our responsibility in this regard is even clearer when we back up to the beginning of the chapter. We know there was a river “flow[ing] from Eden to water the garden” (v. 10), symbolizing that “all fertility emanates from the presence of God.” ¹⁰ Nonetheless there could be no cultivated plants in the garden because “there was still no human being to farm the fertile land” (v. 5). With no gardener and no rain, the ground was watered indiscriminately; a human was needed to irrigate the waters and support a garden.¹¹ Therefore, God “formed the human from the topsoil” (Hebrew wordplay equivalent to “human from the humus”) before planting the garden. God certainly could have watered it another way without needing us, but He chose not to, and the resulting collaborative picture here is a beautiful one. All provision flows from God, but He has chosen to give us an essential part in further channeling his provisions in the natural world. Far from countering God’s creative work by destroying nature, we are intended to work with Him to preserve and further it.

Of course, though created primarily to glorify God, the world was also made to provide us abundantly with the food and resources that we need to live (Gen. 2:16). Yet we don’t need to look far to see that we have often failed in our responsibility to properly care for creation. We live in a fallen world, and sin has fractured the intended harmony of our relationships with God, creation, and each other (as described in Genesis 3:14-24).

I recently heard a striking crystallization of this fallen perspective in Spencer Tracy’s narration in the opening scene of the sprawling 1962 western film “How the West Was Won.” As the camera flies over majestic Western fields and mountains, the narrator tells us that “This land has a name today, and is marked on maps. But the names and the maps all had to be won, won from nature and from primitive man.” This is the fallen perspective – advancing our human purpose on earth is done through defeating nature and other people (derogatively labeled “primitive,” as well) apart from God. This perspective perfectly illustrates the conflict-based relationships that sin brings about, already described for us back in the first chapters of the Bible.

Are we doomed, then, to live helplessly in this way? If this is just the way the world is and the way we are, shouldn’t we just accept that? Apart from Christ the answer would be “yes,” but the New Testament makes it clear that though we are still fallen, the saving work of Christ has brought about a profound change in us. As N.T. Wright makes clear in his book Surprised by Hope, Jesus taught (and the Resurrection vindicated) that the Kingdom of God “was and is breaking in to the present world, to earth.” ¹² Christ’s Resurrection was the first act of the future new creation. If we are truly “born again” into this new reality, this new way of living, we must strive (in the Spirit’s power) to live lives of wholeness and right relationships, putting our sinful nature to death (Colossians 3). In doing so, we would be wise to include Genesis 2 as we seek to follow God’s will and God’s Kingdom, “on earth as it is in heaven” (Matt. 6:10).

In part 2 of this series, David describes how Genesis 1, Genesis 2, and modern scientific accounts offer complementary and mutually enriching perspectives in our understanding of God's creation.

Part of the BioLogos mission, then, is to show how all things hold together in Christ—to show how a Christian worldview integrates the knowledge we have of God through the Scriptures with the knowledge we have of God through the other areas in which he reveals himself as Creator and Redeemer. Our website contains a wealth of Christian scholarship in a wide range of fields—from biology, to cosmology, to mathematics, to Biblical studies, to history, to theology—all demonstrating that the best contemporary science is compatible with Biblical Christian faith. But today we introduce a new tool—the BioLogos Navigator—to make these posts more accessible, and to show how they inter-relate (see sidebar on the right).

Modeled on the astrolabes that early astronomers and sailors used to orient themselves under the heavens, our Navigator makes the cross of Christ the starting point by which we understand the cosmos. Each of the four arms of the cross represents one of the domains of knowledge and experience through which God reveals himself to the world: Scripture, the Church, Nature and Culture. These domains are not in opposition to each other, but are complementary and inter-related areas through which we can recognize God at work in the world. Linking these four domains is a network of specific topics relevant to the science and faith conversation. Their arrangement suggests how each relates to the four domains but also to teach other. Clicking on an individual topic tag highlights not only that topic, but other topics that are linked to it—sometimes in unexpected ways.

Clicking a topic tag a second time takes you to the Topic Landing page: a curated selection of the best resources on that subject from the BioLogos archives. (The image above shows the Christianity & Science—Then and Now Landing page, complete with Navigator and highlighted tags.) At the bottom of each page is a link to our Resource Finder, where you can investigate additional materials on that topic, as well. By exploring the relationships between the topics on the Navigator itself, and by delving deep into each topic via the resources presented on the landing pages, readers can focus on specific aspects of the harmony between science and Christian faith while also getting the wide view of God’s providential work in all things in the heavens and on the earth.

In the coming days and weeks, the BioLogos Navigator will be more fully integrated into the rest of the site, accessible directly from the Forum homepage and from the Resources dropdown list at the top of every page. We’ll also be including features that help place each blog post on the “knowledge map” defined by the domains and topic tags. Finally, the Topic Pages will also be periodically updated with the latest and best new materials in each topic. In the meantime, you can access the Navigator by clicking anywhere on the small image in the sidebar, above, and find a link to this post at the upper right corner of our homepage. So take some time to explore our site with this new tool, which we think will to help orient our readers in the science and faith conversation, while always pointing to Jesus, the Christ, through whom all things were made.

The first video, “10 Questions with Katherine Hayhoe”, introduces the scientist in a brief and lighthearted interview. Hayhoe is presented with 10 questions concerning her personal life and beliefs. When asked, she explains that one thing people should know about Christianity is that having a relationship with the God of the universe is one of the most incredible experiences that a person can have. As the video unfolds, the viewer quickly begins to realize that, despite her unique profession of two seemingly incompatible beliefs, Hayhoe is a remarkably sane and “normal” individual. Her role model, she explains, is her father-- the person who first introduced her to science and showed her that it could be “really cool”. On a more serious note, the scientist admits that being both a scientist and a Christian can be difficult. The most frustrating thing about her position, she says, is the amount of disinformation which is targeted at her very own Christian community.

In the second video, “Climate Change Evangelist”, Katharine Hayhoe delves into deeper discussion of the perceived conflict between climate change and Christian faith. She explains that admitting her identity as a Christian scientist can be uncomfortable. Since evangelicals are the targets of much disinformation concerning science in general -- and specifically the science surrounding climate change -- many people in the church have a misguided view of the subject and do not look kindly at her career choice. One woman encountered by Hayhoe at a church in Texas, for example, believed that global warming was a lie taught in schools to mislead her children. In an effort to realign misguided views like these, Katharine Hayhoe and her husband wrote a book addressing the deep-rooted emotions often associated with climate change. People fear that addressing the climate issue will bring forth changes in the economy and uproot their way of life. However, Hayhoe encourages her viewers to act out of love, as the Bible calls us to do, rather than out of fear. Acting out of love inspires us to consider the poor and disadvantaged people around the globe when we respond to the reality of a changing climate.

In the final segment of this three part video montage, Hayhoe addresses the question of what climate change means. Specifically, she is concerned about how global warming affects people on a personal level. While global warming generally brings to mind melting ice caps and polar bears, its implications are far more widespread, affecting the lives of everyone around the world- from cotton farmers in Texas to public health workers in Chicago. If nothing is done to change current emission levels, the number of days per year which exceed 100 degrees Fahrenheit, for example, will begin to increase dramatically, and if emissions are increased, many areas will even develop extreme conditions like those seen currently in Death Valley. Hayhoe’s goal is to demonstrate clearly that the only way to preserve the world for future generations is to significantly reduce dependence on inefficient means of getting energy and instead transition to cleaner renewable energy sources.

There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.

—Hamlet Act 1, Scene 5

We live in a world driven by the gods of economics, technology and science. Particularly in a time of economic austerity, it is tempting to see the arts or humanities as an optional “extra”—a happy by-product of those true engines of society when they are running smoothly. But in this article we will look at how a biblically informed worldview might turn this perspective on its head, and what the humanities might have to tell us about the present contours of the science and faith conversation.

In his iconic 1959 Rede lecture, “The Two Cultures,” CP Snow noted the dysfunctional relationship between science and the humanities, arguing that the situation is principally the result of our educational system in the West. Ken Arnold, from the medicine and arts focused Wellcome Collection in London, believes that the split continues today, but with the further extension that

In emerging countries . . . amongst the middle classes there is a strong pressure to join the ranks of doctors and scientists and engineers because they see that as the place where future economies are growing. . . . In some ways you could almost begin to feel sorry for the arts and the humanities because they seem to be worth less than the sciences.¹

Is Protestant Christianity also peculiarly prone to such thinking? A skepticism of art in religious spaces as a result of iconoclasm and the reformation, combined with a proud history of the protestant work ethic, economic success, and a profound influence on the history of science, might lead Protestants to be more inclined towards the sciences and technology than to the arts. However, there are more corrosive reasons that science has usurped the humanities in our culture than merely educational or theological bias.

In the early 20th century, logical positivists regarded the humanities as expressions merely of our inner states and desires, but having nothing to do with objective reality. Such imperialistic claims to knowledge denied that other knowledge claims referred to any true reality, and were therefore not really forms of knowledge at all. Bertrand Russell writes,

But if there is a world which is not physical, or not in space-time, it may have a structure which we can never hope to express or to know … Perhaps that is why we know so much physics and so little of anything else.²

Christian scientists are of course very sensitive to this, and work hard to explain that science cannot answer questions of ultimate meaning or the existence of God, which are beyond the scope of science. Often, this line of thinking can be narrow in focus, delineating the limits of the science, and naming those assumptions made by science that cannot be justified empirically. Such arguments can be very fruitful within this narrow context, but we should not be led into thinking that our true perception of reality is limited to such analytic and evidential approaches. There are fields of inquiry that science isn’t able to explain (such as metaphysical judgments, ethics, and beauty), and even our confidence in mathematics— upon which so much of science itself is based—rests upon assumptions that cannot be experimentally demonstrated.

The human condition

Mathematics and the sciences do seem to provide tools by which we are able to perceive the external world and its regularities. However, the arts and humanities, too, are a way of understanding reality, and they tell us less about external reality than the internal human condition. The problem is that the ‘human condition’ seems to have been relegated by many to the realm of mere desire and subjective feeling and, therefore, not reality.

The modernist account of science is that, through our reason, we are somehow able to get outside of nature and describe it objectively. The biblical account, though, has human beings as part of the created order, and so embedded in nature—made from the dust of the earth. Given that, human thought life is also part of the natural world, even despite the fact that it is not best described by the sciences.

The works of Shakespeare, for instance, are part of the created order, as are the poems of Wordsworth, the sculptures of Michaelangelo, and the music of Bach, not to mention children’s nursery rhymes, home decoration, and humming tunes whilst waiting for the bus. As C. S. Lewis wrote, "This is not panache, it is our nature." ³

A little reflection on life reveals something very strange going on here. Somehow, the mythic ‘war’ between science and religion has become the dominant battleground for defending the Christian faith, and competing explanations of the material world are used as apologetic weapons. But the reality is that science plays a peripheral role in our experience of life, not least our life as Christians. Of course that is not to deny the enormous impact of science on the material conditions of our lives, or the prevalence of the products of science. Instead, it is to observe that science plays a facilitatatory role, enabling us to carry out the real core business of our lives, which does not revolve around science. Cars, trains and airplanes are modes of transport to take us to work, or to see family, or go on holiday. Social media provide another way of being in relationship with people. Health services are not an end in themselves, but aim to make people well, so that they can get on with their lives. Why then, when life is not about science, does science dominate our way of thinking about life?

In focusing so much energy on opposing positivism are we not being inadvertently drawn into a positivist way of thinking, that science and material explanations of things are, indeed, our basic reality, what is ultimately true?

A biblical model

“We feel,” wrote the philosopher Ludwig Wittgenstein, “that even when all possible scientific questions have been answered, the problems of life remain completely untouched.” ⁴ Likewise, philosopher Susanne Langer questions any philosophy which claims to be able to explain everything:

Philosophers in every age have attempted to give an account of as much experience as they could. Some have indeed pretended that what they could not explain did not exist; but all the great philosophers have allowed for more than they could explain, and have, therefore, signed beforehand, if not dated, the death-warrant of their philosophies.⁵

Fortunately, the Bible preserves us from total positivist oblivion. There are a great many types of literature represented in the Bible, with the notable exception of scientific writing. If we long to be able to express our deepest emotions, we have the psalms; if we are looking for wise advice, we have the proverbs; if philosophical reflection, Ecclesiastes. There is poetry, song, history, biography, but there is no science. In addition, the Bible refers to the use of the visual arts in, for example, the designs of the tabernacle and temple. The Bible does seem to think the arts and humanities are fundamental for human life, but it doesn’t seem to think that what we think the physical world is constructed of matters much at all.

Do we sometimes read the Bible more like a science textbook than a novel or a poem? Most will agree that each type of literature needs to be read in its own way, but lip-service to that idea notwithstanding, recent arguments prove that it is still possible to read a poem with a scientific mentality—looking out for the ‘facts.’ Is that because we have too high a view of science, or because we have too low a view of the humanities? To say something is poetic is not to declare it ultimately untrue, futile and meaningless—it is to say it is more profound and meaningful and true than many other modes of expression.

According to Langer, part of the problem is the priority that has been accorded to discursive language as the only valid way we have of representing reality to each other. She observes that a study of symbolism shows us that this is actually only one way humans use to abstract from reality, and in fact, the situation even with discursive language isn’t as simple as has been made out. She notes that our sensory organs mediate our perceptions of the world and are already on the job— formulating, framing the world to us—before our cognitive apparatus gets to work. It must be so, or we would not be able to evaluate the importance of the vast array of sensory data we receive and reality would appear as a blur.

A linguistic symbol carries a concept we associate with it, which in turn denotes a reality. In language there is a commonly agreed definition for each word we use, thus enabling communication. But each person also has associations unique to him or her which color any particular concept. Though such personal associations with words are present all at once, they can only be expressed and communicated one at a time, because language is also sequential.

A picture also acts symbolically, though in a different way. Even something as ‘realistic’ as a photograph is likewise a representation of reality and not the reality itself. It also carries with it layers of meaning which reflect the subjective intentions of the person who took the photograph, and opens up for interpretations and associations of the person ‘reading’ the picture. A picture, though, is not sequential. All the information comes at once, and individual blotches of color carry no significance on their own, but only as part of the whole.

No amount of words could ever describe a picture in full. The number of blotches of color and their relations to each other are vast in their complexity, and one could never read words quickly enough to carry the meaning a picture brings in an instant, even if it warrants a far longer period of contemplation. Indeed, though we are only speaking here of visual perception, the same is true of our other sensory inputs, too: they all carry knowledge in quite distinct and profound ways, whilst we, in line with the Greeks, have tended to give sight a special place as the most ‘objective’ of our senses.

As we dig down into empirical science and explore the mechanisms by which sights and sounds and textures are transmitted and processed by the brain, we discover that the meaning of the sense-data which we perceive and which we attempt to describe is likewise profoundly limited by the use of words—much less mathematics—and that our science, as such, represents a tiny fraction of reality.

To suggest, then, that science is the only true way of representing reality—as positivism has done—or to exclude the humanities from our world, leaves us without a proper or even adequate means of expressing the significance we attach to even the most mundane day-to-day activities. Science is very good at describing the regularities of the physical world, but the experience of being human is no less part of the real natural world than are the structure of proteins or the movement of planets, and science does not have the appropriate tools to explore our inner worlds.

Nowadays it seems that Christian cultural life has also too-often failed to fully acknowledge other ways of representing reality than materialist science—ironic because this state of affairs is so at odds with the Bible’s model of using the arts and humanities to profoundly explore the human condition. Perhaps it is time to recover that side of the biblical witness, and remind ourselves that there are more ways of representing the world to each other than positivism has ever dreamt.

It’s true that physics sounds scary to many people, and it can indeed be a difficult topic to learn. Yet I’ve always loved physics (my degrees are in physics rather than astronomy), because of the way that mathematical equations can describe and predict so much of what we see in the world around us. One reason I got into astrophysics is because the universe contains so many bizarre situations that we can’t reproduce on earth, like ultracold, or extremely high density, or extremely high magnetic fields. It’s a fun challenge to figure out which physical process will be the most important when the situation is so dissimilar to everyday experience. But if the word “physics” makes you shrink in distaste or fear, don’t worry. For the rest of this article, we’ll focus on a more friendly topic: astronomy.

In the last decade or two, our knowledge of the universe has grown dramatically as many new telescopes and spacecraft have come online. In this essay, I’ve selected some of my favorite recent astronomy photographs to share with you. As a professional astronomer and a Christian, I feel God has called me to share these wonders with the Church. Many times, these new discoveries are presented without any mention of God, and sometimes in a context of overt atheism. I want to share these things with you in a Christian context, with God as their creator.

The Milky Way

Have you ever seen the Milky Way? If you live in a rural area, you may have seen it many times. If not, it may have been a dramatic surprise when you first saw it while camping or traveling. On a clear night out in the country, the sky is strewn with brilliant stars—many more stars than you can see under city lights.The faintest stars form a creamy, smoky band from horizon to horizon. Our galaxy contains billions of stars, and thousands of those stars are visible to the naked eye. The stars appear in a band across the sky because we are viewing our galaxy edge-on, like looking at the edge of a dinner plate.

When David looked up at the night sky over Israel thousands of years ago, he may have seen the Milky Way, or a comet, or simply the brilliance of the full moon. Whatever the sky looked like that night, it inspired him to sing:

The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge. They have no speech, they use no words; no sound is heard from them. Yet their voice goes out into all the earth, their words to the ends of the world. (Ps. 19:1-4a)

The heavens are displaying the glory of God for all people to hear, proclaiming their message to people of every language, tribe, and nation. Just about anyone who looks up at the night sky feels a sense of wonder. Yet as Christians, we feel more than a vague sense of awe; we know the Creator of the heavens personally, as our own loving Father.

The heavens declare more than God’s glory. The universe is God’s revelation of himself to us, and teaches us about his character. As the Belgic Confession says about “The Means by Which We Know God,”

We know him by two means: First, by the creation, preservation, and government of the universe, since that universe is before our eyes like a beautiful book in which all creatures, great and small, are as letters to make us ponder the invisible things of God: his eternal power and his divinity, as the apostle Paul says in Romans 1:20. Second, he makes himself known to us more openly by his holy and divine Word, as much as we need in this life, for his glory and for the salvation of his own. (Article 2)

The natural world teaches us about God’s glory, power, divinity, faithfulness, extravagance, immensity, love, and other attributes. God’s special revelation in scripture is our primary place to learn of God’s character (Ps. 19 goes on to talk about special revelation in vs. 7), but the natural world can bring the message to our senses in a powerful way beyond mere words on a page. The Holy Spirit can use the natural world to get the message past our hardened or weary hearts. Nature illustrates these attributes in ways that enlarge our imaginations to appreciate afresh the glory of God.

The Sun

The Solar Dynamics Observatory was launched into space in 2010, the latest of several spacecraft to photograph the sun in detail. In Figure 2, the upper photo shows the face of the sun with a sprinkling of sunspots. The sun is powered by nuclear fusion reactions deep in its core which heat the hydrogen and helium gas till it glows. A sunspot is a place on the sun’s surface where the gasses are a bit cooler than the surrounding area, so that it glows less brightly and appears dark.

The lower photo in Figure 2 was taken the same day, but in X-ray light. X-rays are invisible to our eyes, but you have experienced them at the dentist’s office. There, the X-rays are produced by a machine, travel through the mouth, and are detected by film to reveal an image of your teeth. In this image, X-rays are produced by the sun, travel to the Solar Dynamics Observatory, and are detected by a camera to show an image of the sun. In X-rays, the sunspots are the brightest part of the image, not the faintest. If you look at the sunspot on the left edge, you can see bands of particles rising out of the sunspot in a looping path above the sun’s surface and falling back down on it. As the particles follow lines of magnetic field, they emit X-rays. The loops you see are not small—they are about the size of planet Earth! Because of modern spacecraft, telescopes, and cameras, we can see so much more in the heavens than what is visible to the naked eye. Thus, we are seeing more of what the heavens have to declare about God. In Psalm 19, David goes on to describe the sun:

In the heavens God has pitched a tent for the sun. It is like a bridegroom coming out of his chamber, like a champion rejoicing to run his course. It rises at one end of the heavens and makes its circuit to the other; nothing is deprived of its warmth. (vs. 4b-6)

If David had lived today, maybe he would have written about other properties of the sun, like the power of God as seen in nuclear reactions and looping magnetic fields. As it is, he makes two important points. One is the universal warmth of the sun, by which God provides for all life on earth. The other is the faithful path of the sun, day after day, unchanging year after year. In the book of Jeremiah, God promises his people that he will not break his covenant with them, any more than he would break his covenant with day and night and the fixed laws of heaven and earth (33:19-26). The sun is a persistent reminder, woven into our lives, of God’s faithfulness to his promises.

While many Christian colleges actively seek to help their students engage issues of faith and science constructively, few secular colleges are active in promoting the conversation. So what is a student to do? They may find it difficult to find a visible role model or mentor that they admire or respect both spiritually and intellectually. Christian faculty at secular colleges and universities often do not feel safe publicly revealing their faith (due to a real or imagined hostile campus climate) or feel ill-equipped to tackle intimidating and controversial topics.

I was fortunate as an undergraduate to find professors in my field that shared my faith. Though we never talked about faith and science topics explicitly, their very presence encouraged me to consider being a Christian professor in chemistry. I grew spiritually in college, largely due to the community I found in InterVarsity Christian Fellowship. My beliefs were challenged on occasion, but I did not really engage issues like evolution. Like Dennis Venema, I was initially attracted to Michael Behe’s Darwin’s Black Box and the Intelligent Design movement. But as I learned more biology as a graduate student and postdoc, I no longer found this position tenable. I was delighted to find Darrel Falk’s Coming to Peace with Science and Ken Miller’s Finding Darwin’s God. They offered perspectives I had not previously heard, and rejected neither the scientific evidence nor the key tenets of the Christian faith. I was fortunate also to hear Francis Collins give several talks on science and faith. Now I knew someone universally acknowledged as an outstanding scientist that was open about his faith, and I agreed wholeheartedly with his approach.

Now, as a professor, how can I encourage my students to authentic engagement and dialogue on issues like this? Following the example of the Veritas Forum, I can call on a common search for truth. But first it requires understanding what is so special about college students.

College students are often living away from home, are exposed to lots of new ideas in a rigorous environment (including, for many, evolutionary biology and philosophy--taught by professors who are assumed to be greater intellectual authorities than any high school teachers), and are seeking direction for their future careers. In short, it is a time of intense exploration and change for many young people. On residential college campuses, students can experience an unparalleled sense of community, engaging in deep conversations in the dining halls and dormitories. More than any other place, colleges and universities are concentrated locations of our world’s future leaders. Charles Malik, Lebanese philosopher, diplomat, and co-author of the Universal Declaration of Human Rights has said, "The university is a clear-cut fulcrum with which to move the world. Change the university and you change the world." Sadly, the message most students in American universities hear today is one of incompatibility between science and faith.

This is not only a concern for Christian students, but for their non-believing peers as well. If agnostic students think it is inconsistent to embrace both science and Christianity, they are very unlikely to be spiritually curious. If science and faith are viewed as mutually exclusive perspectives, it will be hard for students (and even harder for faculty!) to be credible witnesses for the Christian faith on campuses, not to mention being faith-filled scientists. It is because of my love for God, for truth, and for students that I seek to promote harmony between faith and science, Jesus and genes. And sometimes my students’ lives are changed dramatically.

So what practical steps can we take to foster the kind of conversations that need to be had in the university, and what resources are available to help that project along? While there are many available books on the subject, as well as many on-line resources, I am particularly excited about the new From the Dust documentary and the materials BioLogos is providing to accompany them, especially when students can explore then in a supportive group setting. To facilitate exactly that kind of open dialogue, I was invited to develop a study guide to accompany the film, and to try it out in my own college community.

I liked using From the Dust as the centerpiece of the group study plan, as it is visually, theologically and emotionally stimulating. It also takes the Bible seriously and is aimed at starting conversations, rather than ending them with dogmatic answers to challenging questions. I also knew that even though From the Dust is only an hour long, it is packed with potential discussion topics and is probably best viewed over the course of a few sessions instead of all at once. Since I was focused mainly on a Christian audience, I decided to have the students read from Genesis before we started the film, read it again halfway through the film, and read it a third time after we’d finished the film. To deepen the discussion further, and to give students something to think about each week between our sessions, I added six scholarly yet accessible articles that are freely available online from BioLogos, the Faraday Institute, or the American Scientific Affiliation.

My students, several of whom I did not know prior to our science & faith study, were from both Protestant and Catholic backgrounds. Many had not deeply engaged the intersection of science and faith previously, but were dissatisfied with what they had been taught at church or at Christian primary or secondary schools. While individual responses at each session varied, the group was overwhelmingly positive about the content and the process of our study together. Many of the questions we discussed were difficult and emotional, and having the space to wrestle with the ideas together in a supportive group was incredibly helpful.

Tomorrow, I’ll give some more concrete details on how the Study Guide can be used in college and other settings, and also highlight another new film-based resource: The Faraday Institute’s Test of Faith project.

Suppose a man falls among thieves, or wild beasts; is shipwrecked at sea by a sudden gale; is killed by a falling house or tree. Suppose another man wandering through the desert finds help in his straits; having been tossed by the waves, reaches harbor; miraculously escapes death by a finger’s breadth. Carnal reason ascribes all such happenings, whether prosperous or adverse, to fortune. But anyone who has been taught by Christ’s lips that all the hairs if his head are numbered [Matt. 10:30] will look further afield for a cause, and will consider that all events are governed by God’s secret plan.

In this passage, Calvin presents belief in “fortune” as evidence of carnal reasoning, and statements like this one have contributed to a widely-held notion that modern scientific understandings of the role that randomness plays in nature is inconsistent with belief in divine providence. In other words, if “randomness” equals blind and capricious “fortune,” then how can God be said to be working all things to his ends?

But Calvin could not have known of the very different understanding of randomness held by today’s scholars. Physical scientists, mathematicians, and statisticians have not yet agreed on a single unambiguous definition of the term “randomness,” but among these scientists, the term consistently refers to a family of related concepts focusing on unpredictability of the outcomes of single events and the absence of pattern in sequences of outcomes. I like this statement by John Polkinghorne, “Chance doesn't mean meaningless randomness, but historical contingency. This happens rather than that, and that's the way that novelty, new things, come about.” In Polkinghorne’s view, chance is an agent of creativity and can be perceived as being purposeful.

In fact, there are abundant examples of phenomena in nature in which randomness plays a role one could understand as being purposeful. For example, osmosis is a marvelous mechanism that enables all 10 trillion cells in our bodies to be nourished – it depends on the random motion of molecules. The human immune system is able to defend the body against attacks from millions of different microorganisms using a relatively small number of building blocks and random combinations of these to fashion defenses specific to each adversary. We never take a breath and find it to be all nitrogen or carbon dioxide – random motion of molecules keeps oxygen close to uniformly distributed throughout the atmosphere.

In 2007, a British statistician, David Bartholomew published God, Chance, and Purpose in which he argues that God “can have it both ways”—that he can use low level randomness to accomplish divine purposes while simultaneously maintaining order at a higher level. Of course, we cannot prove that God ordained these random processes to achieve divine purposes in the world. But to a person of faith, such an interpretation in both consistent with the observations we make in science and with the Scriptural notion of God’s providential care for the world.

Considerations like these led the John Templeton Foundation to provide a generous grant of $1.69 million to support a new research initiative on the theme of Randomness and Divine providence. Beginning this past summer, the program has the purpose of providing support for solid theoretical exploration of the kinds of ideas and possibilities expressed above—involving theology, philosophy, natural science, mathematics, and statistics. The grant will support individual scholars and teams of scholars who are willing to devote a significant amount of time between March of 2013 and June of 2015 to such work, and the project’s request for proposals suggests the following as questions researchers might pursue:

• How might God work providentially through indeterminate processes? Can recent advances in understanding the nature of randomness offered by algorithmic information theory, physics, biology, and other sciences provide insight into this question?
• Can we bring clarity to the concept of "randomness"? Philosophers and scientists have tried on occasion to give precise definitions of when a process is random, but more work needs to be done on the question. How do (or should) conceptions of randomness vary across academic disciplines?
• What are some possible implications of randomness for hiding or unfolding divine creativity and purpose in the world? Could God use randomness to (1) generate creativity, (2) hide divine actions, or (3) unfold information? Why might God do so?
• How might we identify and come to understand a significant collection of nondeterministic processes in which agents could intentionally employ randomness to bring about purposeful results?
• How might we mathematically and physically model random processes in ways that help us understand how divine providence could be exercised in a "chance-governed" world?
• How do "laws and orders" in nature interplay with "chance and randomness" in bringing about results that can be interpreted as aspects of divine providence?
• Might randomness be evidence of limitations in human knowledge but nothing more? Or might it be evidence of ontological indeterminism? Might this be tested?
• What implications does randomness have for aspects of God’s relationship with the physical world such as God’s relationship to time and God’s role in causation? How might randomness be reconciled with God’s foreknowledge?
• How might an understanding of providence based on an extended Molinism and/or open theology incorporate randomness? For example, could an extended Molinism provide a plausible account of the relationship between quantum mechanics and divine providence?
• What are some theodical implications of randomness, particularly for the issue of natural evil?
• How have the theological traditions of Augustine, Maimonides, Aquinas, Luther, and Calvin addressed chance and fortune? In what ways might they incorporate ontological randomness?
• How do or could religions other than the Judeo/Christian tradition understand and incorporate randomness?
• How is the concept of randomness understood by advocates of secularism, naturalism, and new atheism? What are the strengths and weaknesses of these usages?
• How might an understanding of randomness in the world alter our conceptions of divinity, especially our understanding of divine providence?

Despite the range of issues mentioned above, research is by no means restricted only to these topics. In fact, the structure of the program is designed to foster collaboration and build community between scholars, with the end of expanding the range and integration of their work: two conferences will be held to bring scholars together with each other and then with members of the public—one at Calvin College in 2013 and the other at Fuller Theological Seminary in 2015. To get more information and to learn how to submit a proposal, see the project website; then join us in exploring the truth that all creation glorifies God—even randomness!

After the “information dump” using the fruit fly examples, it’s time for a class discussion/application before the students drift off too much. Ok, here’s a slide that shows the chromosome structure of a group of organisms that other lines of evidence suggest are part of a group of related species. What do you observe? Do you think these species are related? If so, what explains the differences you observe?

What the students don’t know is that the slide shows human chromosomes, and those of our closest living relative, the chimpanzee. Oblivious to this knowledge, they easily arrive at the correct answer: yes, the evidence is strong that these are quite recently diverged species, and that a chromosome fusion or fission event explains the differences in chromosome structure between them. When I tell them that every other species in this grouping has the higher chromosome number/structure, they correctly deduce that the species with the lower chromosome number should show evidence of a fusion event in the form of “telomere” sequences at the fusion point and an inactive “centromere” at the location suggested by comparison to the other, related genome.

Easy.

As I look around the room, I see the students are satisfied. I cover some difficult material in this course, and the students are obviously pleased that this topic is so easy to handle. The lines of evidence are easy to follow, and it’s easy to predict and test one’s hypotheses. Then, only after they’ve seen the evidence at least once without the baggage that will inevitably come, I ask them if they know what two species they’ve just compared.

As a biology professor at a primarily undergraduate, evangelical, liberal arts and sciences university, I have the profound privilege of teaching the principles of evolutionary biology to a variety of students, both biology majors and non-majors. As one might expect, teaching this subject matter at times engenders controversy, crises of faith, anger and fear in students (and others). These types of sorrows are relatively well known and have been discussed here on BioLogos by several authors. Yet there are also great joys associated with teaching evolutionary biology in a Christian setting, and in this post I reflect primarily on these as a counter-balance to the more frequent stories of conflict and struggle.

The sorrows …

Lest anyone think that this post is an attempt to present an overly-optimistic or whitewashed view of teaching evolution in an evangelical setting, let me acknowledge and affirm that the pain that many (yes, most) evangelical students go through as they learn about evolution is substantial and real. I have had too many long conversations with students caught between their faith communities and the science to deny this reality. I have seen students struggle with their faith, close their minds to the scientific evidence, and even resolutely declare that no amount of evidence would ever be enough to convince them that evolution is real. I have seen anger, hurt and fear. I have seen students willing to discard the nearly the entirety of modern science in order to maintain a particular anti-evolutionary view.

For me personally, the most difficult circumstances to watch are students who feel torn between the evidence and their faith. In some cases these are extremely bright students, who easily see the strength of the evidence, but feel the need to remain unengaged and uncommitted because they fear a backlash from their churches, or (especially) their parents. While an evangelical university can be a wonderful, safe environment for students to explore these issues, that environment doesn’t follow them home. These struggles are painful to watch, and I’ve spent more than a few hours in prayer for students facing them.

… and the joys

Yet for all these issues, I thoroughly enjoy teaching evolution at an evangelical university. Of course I do not enjoy the anguish it can produce for some of my students – far from it! Fortunately, conflict and emotional turmoil are not the whole story, and many evangelical students report that learning about evolution was a valuable, enriching experience, regardless of their views after the fact.

One of the things I enjoy most is that teaching evolution is never dull in an evangelical setting. My students might snooze through a class on cellular respiration, or be tempted to surf Facebook when they should be applying their reasoning skills to problems in genetics, but whenever evolution is the topic I have everyone’s full attention. Whatever else, evolution matters. That intensity of student engagement is invigorating, and the students feel it too. Regardless of where students ultimately decide to “land” on the issue, many report that they enjoyed the process – the exchange of ideas, the discussions and debates, and the new understandings gained.

In addition to the electrifying interest the topic holds for evangelical students, learning about evolution is also by nature a multidisciplinary enterprise and opportunity for personal growth. Students are not merely gaining a larger perspective in biology, but fitting that new understanding into their knowledge of Scripture, church history, and their own faith journey. Often in class students will contribute what they have learned in other courses to the discussion: courses dealing with the setting and context of Genesis, courses on church history, and courses on hermeneutics and exegesis frequently are drawn upon. It is for this reason that I feel learning about evolution in a Christian liberal arts university is one of the very best places to do so, providing the institution treats the topics fairly. In this setting, resources are available for all of the questions that evolution engenders for Christians, not merely the scientific ones. Moreover, faculty are generally able to assist students with resources that address these extra-scientific issues, and provide a safe and non-judgmental environment for students to learn. The ability to learn what can be faith-shaking material in a setting surrounded by professors committed to the academic and spiritual growth of their students can make all the difference. To be sure, this environment can be one of personal turmoil for students, but with that turmoil comes a rare opportunity for intellectual and spiritual growth in a way that other areas of biology simply cannot provide.

Many of my students, regardless of whether they ultimately accept or reject the evidence for evolution, report that they have grown spiritually through their learning process. Contrary to popular opinion, in my experience most who do come to accept the evidence for evolution also report this growth. They feel closer to God, not further from Him. They feel that they have a deeper appreciation for, and understanding of, His creation. They feel that their faith is now more their own, rather than merely that of their parents. Most importantly, they feel free: that they need no longer be afraid of evolution, but celebrate it as the mechanism by which God has populated His world with “endless forms, most beautiful.”

Seeing students experience that freedom is something that one cannot test on an exam, nor encapsulate as a teaching outcome – but it is a deep joy of my teaching career.

Asa Gray

If Thomas Huxley earned the title of "Darwin's bulldog," then Asa Gray should be remembered as "Darwin's dove." Whereas Huxley enjoyed a good fight in his defense of Darwin's theory, Gray sought to mediate and bring sides together around a common understanding of "good science." As Darwin's strongest and most vocal scientific ally in the United States, Gray recognized the scientific importance of Darwin's efforts for the growing professionalism of biological researchers.

But as an orthodox Christian, a Presbyterian firmly devoted to the faith expressed in the Nicene Creed, Gray saw in Darwin's theory both evidence for his philosophical commitment to natural theology and support for his opposition to the idealism advocated by Louis Agassiz and the Naturphilosophen in both Europe and America. Indeed, Agassiz's advocacy of Platonic forms as a basis of biological understanding (e.g., "A species is a thought of the creator")¹ would be a major source of American opposition to Darwin's theory.

Professor of botany at Harvard during most of the middle half of the nineteenth century, Gray was one of the few members of the scientific community to whom Darwin revealed his theory before the publication of On the Origin of Species, and, from what I can tell, the only American. Gray and Darwin met briefly in January 1839 during one of Gray's visits to England. Later, during the 1850s, Darwin wrote Gray on several occasions requesting information--a practice that Darwin frequently employed. In 1854, Darwin's friend and confidant, Joseph Hooker, showed Darwin Gray's review of Hooker's Flora of New Zealand, in which Gray had argued strongly against Louis Agassiz's idealism and had raised questions from his own work on the stability of species. Gray was not yet ready to deny their permanence, but hybrids and other observations were beginning to trouble him.

The next year Gray wrote a lucid and penetrating positive evaluation of Alphonse De Candolle's two-volume Géographie botanique raisonnée, a pioneering work dealing with plant geography and distribution from a statistical perspective. Hooker had sneeringly dismissed the work. In A. Hunter Dupree's authoritative biography of Gray, he describes Gray's puzzlement at Hooker's response in these terms:

Although in the long view Gray's evaluation of the epoch-making nature of De Candolle's book was more justified than Hooker's sneers, [Gray was confused by his response, for] Hooker seemed to be talking with a more comprehensive theory definitely in mind, some reason for taking his position, which he did not divulge and which his friend [Gray] did not possess.²

Darwin, however, saw in both Gray's review of Hooker's book and in his comments on De Candolle's tome that Gray was troubled by some of the same empirical data that had been bothering him. In April 1855, Darwin wrote Gray to urge that Gray update his Manual of the Botany of the Northern United States first published in 1848, and especially to address the issue of the range of Alpine plants in the United States. Specifically, he said: "Now I would say it is your duty to generalise as far as you safely can from your as yet completed work."³

Behind this request was Darwin's desire to test his impression that Gray could make a good ally. Gray passed the test, and finally, in July 1857, Darwin let Gray in on his theory of the transmutation of species. Gray was never an uncritical supporter, and there are many evidences in the correspondence between these two scientists that Gray was willing to challenge Darwin and disagree with some of his conclusions. Nevertheless, Gray saw the importance of Darwin's work and the ways in which it provided answers to the troublesome issues that he had confronted in his own botanical efforts.

Gray responds to Darwin's theory

After considerable interchange--one might even say debate--among Gray, Darwin, and Hooker, Gray wrote to Hooker in October 1859 (one month before the publication of On the Origin of Species) saying that he had absolutely no problem with cognate species arising by variation. He did, however, raise a concern that would be the source of much future discussion. He wondered about Darwin's "carry[ing] out this view to its ultimate and legitimate results,--how [do] you connect the philosophy of religion with the philosophy of your science." He added: "I should feel uneasy if I could not connect them into a consistent whole--i.e., fundamental principles of science should not be in conflict."⁴

When Origins was published, Gray wrote a clear, positive, yet critical review in The American Journal of Science. Aware of mounting religious opposition, he ended his review by arguing that whereas one could use Darwin's theory in support of an atheistic view of Nature, one could use any scientific theory in that way. He wrote: "The theory of gravitation and ... the nebular hypothesis assume a universal and ultimate physical cause, from which the effects in nature must necessarily have resulted."⁵ He did not see the physicists and astronomers who adopted Newton's theories as atheists or pantheists, though Leibniz earlier had raised such reservations. And a similar situation existed with the origin of species by natural selection. Darwin, Gray continued: "merely takes up a particular, proximate cause, or set of such causes, from which, it is argued, the present diversity of species has or may have contingently resulted. The author does not say necessarily resulted."⁶

This far Gray could go with Darwin. But there was a point at which he parted company, and that was the fortuitous randomness of the process that Darwin's theory seemed to imply.

Darwin’s finches are some of the most visible and recognizable symbols of evolution in the world today. Biology textbooks feature them prominently, and the National Academy of Sciences has enshrined them in the entrance of their headquarters in Washington, DC. Surely the finches that Darwin collected on the Galápagos islands were a central feature of his evolutionary theory, right?

Actually, the Galápagos finches are never even mentioned in Darwin’s famous work On the Origin of Species. Nor do they appear in Darwin’s famous notebooks on “Transmutation of Species”, in which he formulated the idea of evolution by natural selection.¹ Even Darwin’s private diary of his voyage on the HMS Beagle only mentions the Galápagos finches briefly in passing.²

It was only in 1845, in the second edition of The Voyage of the Beagle, that Darwin included a tantalizing sentence about the Galápagos finches:

Seeing this gradation and diversity of structure in one small, intimately related group of birds, one might really fancy that from an original paucity of birds in this archipelago, one species had been taken and modified for different ends.³

However insightful this statement may have been, Darwin never published anything else about the Galápagos finches for the rest of his life. Nor did he publically present these birds as direct evidence for this theory of evolution.⁴

If these finches were so important to Darwin’s evolutionary theory, why did he remain silent about them? One of his comments in The Voyage of the Beagle provides us with a clue:

Unfortunately most of the specimens of the finch tribe were mingled together; but I have strong reasons to suspect that some of the species of the subgroup Geospiza are confined to separate islands.⁵

When Darwin was exploring the Galápagos himself in 1835, he had not formulated his theory of evolution yet, and thus he did know what data would be necessary to make definitive conclusions about finch evolution. In particular, he did not keep careful track of which of his specimens came from which islands. Moreover, as was customary among naturalists at that time, Darwin only collected a small number specimens—he brought home only 31 finches and 64 total birds from the Galápagos.⁶

Though Darwin sensed that these birds were truly special, he lacked sufficient evidence to reach any specific conclusions about their evolutionary origins. It would be up to the rest of the scientific community to carry out the necessary empirical research. Subsequent expeditions in 1868, 1891, 1897, and 1905 brought back thousands of Galápagos finch specimens, but instead of unlocking the mysteries of evolutionary theory, the Galápagos finches became a great enigma.⁷

A century after Darwin's voyage, scientists still struggled to explain the staggering variety of finches on this tiny, remote archipelago. By the mid-1930’s, British Museum ornithologist Percy Lowe argued that the finches presented a "biological problem of first class importance", and he told the British Association for the Advancement of Science that the finches displayed a "bewildering diversity, intergradation, and distribution".⁸ Who would be up to the challenge of making sense of such tremendous biological complexity? It was David Lack.

David Lack

Ornithologist David Lack

David Lack had an exceptionally keen eye for bird-watching, and he possessed a passion to match it. By age 15, he had already observed 100 distinct species of birds, and before entering college, authored his first scientific paper. At Cambridge University in the early 1930’s, Lack was disappointed to find that his zoology professors taught “nothing about evolution, ecology, behavior or genetics, and of course nothing about birds.”⁹ In fact, at that time, there were only two professional ornithologists in all of Britain!

Thus David Lack took it upon himself to create his own learning opportunities. As an undergraduate, he became the president of the Cambridge Ornithological Club, traveled to Greenland for a bird-watching expedition, and cultivated a relationship with the prominent biologist Julian Huxley (grandson of Thomas Henry Huxley). Huxley was an inspiring mentor and encouraged Lack to expand his research further by studying tropical birds.¹⁰ Following this advice, Lack embarked on a research trip to Tanzania in the summer of 1934, but his greatest adventure was yet to come.

In 1937, Lack became fascinated by the scientific mysteries surrounding the Galápagos finches. But in order to study their behavior, Lack would need to travel to remote islands halfway around the world. How could he possibly get there? Once again, Julian Huxley was tremendously supportive and raised funds from two prominent scientific societies to pay for his expedition. After a long delay, David Lack and five companions finally set off on their journey.

Instead of residing in comfortable quarters aboard a royal naval ship, Lack’s group subsisted on a shoestring budget, traveled on commercial steamers, and stayed with local settlers. Their experience was definitely not a romantic tale of imperial expedition:

The Galápagos are interesting, but scarcely a residential paradise. The biological peculiarities are offset by an enervating climate, monotonous scenery, dense thorn scrub, cactus spines, loose sharp lava, food deficiencies, water shortage, black rats, fleas, jiggers, ants, mosquitoes, scorpions, Ecuadorian Indians of doubtful honesty, and dejected, disillusioned European settlers.¹¹

Whereas Charles Darwin spent only nineteen days on the shores of the Galápagos, Lack and his crew conducted more than five months of meticulous and exhausting study in the harsh climate. At that time, even the finches themselves provided little solace. Lack wrote,

Darwin’s finches are dull to look at, not only in their orderly ranks in museum trays, but also when they hop about the ground or perch in the trees of the Galápagos, making dull unmusical noises. Only the variety of their beaks and the number of their species excite attention.¹²

The repetitive tedium requisite for important scientific discoveries is rarely discussed in public, and even today many bright-eyed science students become disillusioned by the painstaking work demanded by their Ph.D. programs. But one of the things that distinguishes great scientists is their unwavering commitment and tenacity in completing major projects. David Lack's efforts were not in vain:

"Despite his personal discomforts (or perhaps because of them), Lack did see something on the Galápagos that no one had ever seen before—natural selection at work among its finches through interspecies competition." ¹³

When the birds’ breeding season ended in 1939, Lack was ready to return to his home in England. But the captive finches that he had brought with him fared so badly on the voyage home that he detoured to San Francisco and put them in the care of the California Academy of Sciences. Turning this mishap into an opportunity, Lack stayed there for five additional months to study the Academy’s enormous collection of Galápagos finch specimens.¹⁴

To complete his systematic research, Lack then travelled across the United States to study the Galápagos finch collection housed at the American Museum in New York.¹⁵ Altogether, Lack examined more than 8000 specimens and specifically measured the length, width, and depth of all their beaks.¹⁶

Lack’s final obstacle was in getting his research published. Though he completed his academic manuscript “The Galápagos Finches—A Study in Variation” in 1940, paper shortages during World War II delayed its publication by the California Academy of Sciences until 1945. Were he only interested in making an original contribution to science, Lack could have stopped here and congratulated himself on a job well-done. However, his motivation sprung from a deeper source:

David Lack's drawing of 14 species of Galápagos finches, p. 19 of Darwin’s Finches

"I did not watch birds primarily for scientific reasons but for sheer enjoyment, and from the age of 15 onward returned day after day in a glow of excitement after seeing a new bird or a new habit." ¹⁷

Lack’s joyful fascination with the Galápagos finches inspired him to continue developing his conclusions long after returning from his expedition. While waiting for his academic paper to be published, he began writing a book that would enable students and the general public to share his excitement about these remarkable birds and the evolutionary processes that shaped them.

First published in 1947, Lack’s book became tremendously influential. Before this time, biology textbooks had never even mentioned the Galápagos finches. But after David Lack’s study, the finches became a primary example of evolution by natural selection, specifically adaptive radiation. Not only did textbooks fully rely on Lack’s findings, they also followed his lead in calling them “Darwin’s finches”, the title of Lack’s famous book.¹⁸

Iconic Finches

What was it about these birds that made them such a prominent symbol of evolution? As Darwin himself pointed out, the numerous Galápagos finch populations each have distinctive beaks, and he speculated that they could have evolved from an ancestral species that came to the islands. But a complete picture of finch evolution would have to wait another hundred years, when David Lack arrived.

During his five months on the Galápagos, including both the rainy and dry seasons, Lack observed that these beak differences enable the finches to subsist on different kinds of food:

The beak differences between most of the genera and subgenera of Darwin's finches are clearly correlated with differences in feeding methods. This is well borne out by the heavy, finch-like beak of the seed-eating Geospiza, the long beak of the flower-probing Cactornis, the somewhat parrot-like beak of the leaf, bud, and fruit-eating Platyspiza, the woodpecker-like beak of the woodboring Catcospiza, and the warbler-like beaks of the insect-eating certhidea and Pinaroloxias.¹⁹

Lack's image of beak adaptations from Darwin’s Finches

Specializing in such different sources of food enables these finches to live in close proximity without directly competing with each other or driving populations to extinction. The fact that so many of these closely related finches are able to co-exist is a remarkable fact in itself. As Lack himself put it, “It is not only the origin, but also the persistence, of new species which require explanation.”²⁰

But it is also fascinating to consider how these birds got to be so different in the first place. How did a finch come to have a beak like a “parrot”, “woodpecker”, or “warbler”? The answer lies in the distinct characteristics of the Galápagos. Because the islands are so remote, no actual parrots, woodpeckers, or warblers ever settled on it. In the absence of these species, the Galápagos finches were able to adopt feeding habits and forms that they would never have taken on a large continent full of other birds competing for food. The isolation of these islands offered just the right conditions for us to see living examples of adaptive radiation.²¹

Conclusion

Considering the immense popularity of the Galápagos finches, it is quite surprising to learn that Charles Darwin himself had so little to say about them. In fact, it was actually David Lack, one century later, who conducted the critical research that immortalized the finches in biology textbooks and popular lore. By naming his landmark book Darwin’s Finches,²² Lack paid homage to the man whose voyage on the HMS Beagle helped transform the study of natural history. But at the same time, Lack also obscured the fact that evolutionary biology is an enterprise conducted by a large community of brilliant scholars, not just the product of one man’s efforts.

This tendency to immortalize “great men of science” has also led many people to refer to modern evolutionary theory as Darwinism, despite the fact that it has substantially changed and developed over the past 150 years. It is important to give credit where credit is due, and if that’s the case, we should seriously reconsider how we refer to the Galapagos finches. Evolutionary biologist Dolph Schluter, who studied the finches several decades after David Lack, had this to say:

I find Lack's intuition really stunning given how little information he had. He's my hero actually… They should be called Lack's finches.²³

In the second part of this series, we’ll explore the fact that David Lack, in addition to being a world-renowned evolutionary biologist, was also a devout Christian. His study of evolutionary theory did not cause him to lose his faith; in fact, he actually converted to Christianity after completing his Galápagos finch research.

It has been widely reported that the moniker “God particle” was not its originator’s first choice. Still, Leon Lederman, director emeritus of Fermilab and Nobel laureate for neutrino research, did accept the nickname “God particle” because the particle is “so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive.” “God particle” was quickly accepted by the press and general public because it seemed an appropriate title for a particle theorized to give mass to all elementary matter particles and the force carrying W and Z bosons. Serving this mass-giving function since near the beginning of the universe, a Higgs field (more fundamental than the actual Higgs boson ) must necessarily exist everywhere in the universe and be unchanging. With an omnipresent and immutable field, analogies between the Higgs boson and God naturally developed within the press and the public—“God particle” became deeply rooted. Relatedly, the Higgs boson become an excellent source for theological analogies. (See for example this article.)

Nevertheless, as physicists seek to emphasize, neither the Higgs boson particle nor its field have religious properties. Thus, elementary particle physicists are not fond of the “God particle” appellation. In the opinion of Oliver Buchmueller, of CERN’s CMS group, calling the Higgs boson the “God particle is completely inappropriate. It’s not doing justice to the Higgs and what we think its role in the universe is. It has nothing to do with God“. As Pippa Wells, another CERN scientist expressed, “Calling [it] the God particle … confuses people about what we are trying to do at CERN”. (Source: Reuters)

One alternate name for the Higgs particle that is used within the physics community is the “BEH” particle. “BEH” stands for Brout–Englert–Higgs, three of the six authors of 1964 papers that first proposed a mechanism for giving mass to elementary particles. In addition to Peter Higgs, the five other authors are Robert Brout and Francois Englert, and Tom Kibble, C.R. Hagen, and Gerald Guralnik. The process for giving mass to particles is thus sometimes referred to not just as the Higgs mechanism, but as the Brout–Englert–Higgs–Hagen–Guralnik–Kibble (BEHHGK) mechanism. (Saying all six names a couple of times makes it obvious why we most often only call it the Higgs.)

But issues of naming aside, what is the Higgs and why is it so elusive? According to the Standard Model, the particles that compose matter (the quarks and leptons) are in a category called spin-1/2 particles. The force carrying particles (the photon, the W's, the Z, and the gluons) are spin-1 particles. What the physicists above proposed was the existence of a type of spinless, or spin-0 particle. Not only does the Higgs boson form its own class of particles, it also gives mass to itself and to all the other particles that have mass: to all of the leptons and quarks, and to the W's and Z bosons, but not photons or gluons. This set of relationships is shown in the image below, indicated by the lines connecting the Higgs to these other particles. There are no lines directly connecting the Higgs boson to photons and gluons because the Higgs boson does not interact with these force carrying particles and, thus, photons and gluons remain massless.

But the story of the Higgs particle actually begins with the associated Higgs field, an invisible field (something like a generalization of an electric field) that has a non-zero, constant value everywhere throughout the universe. This Higgs field continuously interacts with all matter particles and the W and Z force carrying particles. Matter and massive force particles are slowed down as they move through the Higgs field, just as are balls rolling through thick mud. The Higgs field is sometimes described as a “cosmic molasses”. Different particles interact with the Higgs field to varying degrees—those interacting more, are slowed down more, those interacting less are slowed down less. Slowing down more equates to acquiring more mass. If not for the Higgs field, all particles would be massless, zipping through the universe at the speed of light. The universe would be without structure—no galaxies, no plants, no life. Without the Higgs field, not even atoms could have formed.

It was theoretically possible for elementary particles to have mass without needing to acquire it through interaction with a Higgs-like field. However, as the standard model of elementary particles developed in the 1950’s and 1960’s, elementary particle theorists realized that if particles had their own innate mass, rather than acquiring it, many beautiful symmetries of particle interaction equations would be broken. To keep the beauty and symmetry in the theory was the essential reason the BEHHGK mechanism was developed, which immediately led to the prediction of Higgs bosons.

When there is enough external energy in a given volume, the Higgs field also produces Higgs bosons. But the Higgs bosons are very unstable and quickly decay. This is the process that enabled the discovery of the Higgs boson at CERN. At CERN, protons are accelerated to high energies via electric fields and directed in circular paths via magnetic fields. The protons then collide and release large amounts of energy. When sufficient energy is released in a collision, the Higgs field can use this energy to produce Higgs bosons. The Higgs bosons quickly decay leaving evidence of their existence through particular combinations of leftover particles that they have decayed into. Among those predicted by the mathematics of the Standard model are the muons and electrons identified by the CERN experimenters. The image at the top shows the identities and paths of particles produced in one of the CERN proton-proton collisions whose results fit with what would be expected from the decay of a Higgs boson.

For a proton-proton collision at the CERN LHC, the above diagrams show both the dominant modes for creation of a Higgs with a mass around 125 GeV, and the two dominant decay channels (modes). The creation mechanism (shown schematically in the left half of each diagram above) involves virtual gluons, the carriers of the strong nuclear force (represented by squiggly purple lines) from the protons. The gluons fuse into a virtual top quark loop (medium blue triangle), which then emits a Higgs boson (squiggly yellow line). The top quark couples more strongly to the Higgs than any of the five other quarks, so the top quark contributes the dominant loop.

The Higgs boson then dominantly decays into either (i) 2 gamma ray photons (the squiggly green lines) via another intermediate virtual top quark loop or a virtual W gauge particle loop (dark blue triangle), or (ii) two Z0 gauge particles (squiggly dark blue lines), which each then decay into a lepton (specifically an electron or a muon)/anti-lepton pair (light blue lines).

The likely discovery of the Higgs boson, and its implied existence of the associated Higgs field, is an amazing success for CERN. Past research and experience at Fermilab and by elementary particle physicists throughout the world also contributed to the discovery. The Higgs boson was the remaining particle in the Standard Model of Particle Physics to be found. With it, the Standard Model is in some sense complete. (Nevertheless, many questions about the Standard Model still remain—many inspired once again by beauty and symmetry. In particular, several numeric values associated with particle masses and interactions could only be experimentally measured, as with the Higgs, and not predicted from the Standard Model.)

With the apparent success of these experiments and seeming confirmation that the physical universe is, indeed, reflected by the complex and beautiful mathematics of the Standard Model, the international physics community is eager to keep delving deeper into the structure of creation. In addition to trying to verify that the 125 GeV particle is, indeed, the Higgs spinless particle and not some more exotic, new particle, CERN physicists are simultaneously seeking to discover an entire new class of particles, resulting from a theorized symmetry called supersymmetry. Discovery of the associated particles, if they exist, will likely take a few more years. For these discoveries we can only wait in anticipation.

Updated July 12, 2012.

Judging from the flurry of headlines over the past week, one might be tempted to think that proof positive of God’s existence (or lack thereof) had just appeared out of a 27-km-tunnel buried beneath the Swiss-French border. This frenzy of news headlines and blog titles hailed the recent news that CERN’s Large Hadron Collider has discovered a brand new particle of a mass of 125-126 GeV, which is assumed to be the Higgs boson, or the so-called “God particle.” The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity? Is there actually any theological or religious significance in Higgs physics at all?

The short answer is “no,” which becomes apparent when one considers the widely-reported story of how it got named. In 1993, Nobel Laureate physicist Leon Lederman, along with science writer Dick Teresi, wrote a book detailing the history of particle physics starting with Pre-Socratic Greek philosophy Democritus and culminating with the hunt for the Higgs boson. Until this latest discovery, the Higgs boson was the elusive final missing piece of the puzzle known as the Standard Model—a collection of the fundamental particles that constitute our universe and the complex and mathematically-sophisticated relationships between them. Considering how incredibly difficult finding the Higgs boson was proving to be, Lederman wanted to name the book after that “goddamn particle,” according to some of his collaborators. His editor, however, would not allow it and so the name was shortened to “The God Particle: If the Universe Is the Answer, What is the Question?” And thus ‘the God particle’ was born, carrying with it more than enough social baggage for such a miniscule particle.

Particle physicist Dr. Zosia Krusberg (at right) is visiting assistant professor of physics and astronomy at Vassar College and thinks “the term ‘god particle’ is unfortunate. The Higgs boson is no more (or less) divine or spiritually significant than any other elementary particle within the standard model of particle physics.” It may be fundamental to explaining one of the most basic characteristics of the universe—namely the existence of matter and mass in addition to energy—but “it is no more (or less) important than any other physics principle underlying the Standard Model.”

Last week’s discovery was monumental in that it may have finally provided experimental evidence for the Higgs Mechanism and defined the specific energy of the resulting Higgs boson, but even this “breakthrough” for particle physics leaves many scientific questions unresolved. Finding the Higgs boson completes the Standard Model, but it does not do away with many other questions and shortcomings of the current state of particle physics, such as the constituent particles of dark matter, a quantum theory of gravity, and other “mathematically subtle problems.” Not to mention that there is still significant work to be done to determine the exact nature of this newly-found particle. According to Dr. Krusberg, this particle might behave just as the Standard Model predicts or it could instead be “a Higgs-like particle that will serve as a gateway into explorations of physics beyond the Standard Model." Krusberg continued, “And I guarantee that it is this latter scenario that most of us are hoping for: physicists love nothing more than discovering the shortcomings of their theories, since this is the first step toward more fundamental theories with even more predictive power!”

No, finding the Higgs boson does not answer all the questions of particle physics, much less lend insight into the existence (or not) of God. For that reason, Dr. Krusberg (like most physicists) bemoans the term ‘God particle’ and insists, “There really is nothing either literally or metaphorically god-like about the Higgs boson.” Indeed, one writer for the British journal The Guardian reached such a point of frustration about the name that he ran a competition for alternatives. The winner was “the champagne flute boson,” ostensibly because the bottom of a champagne bottle is an excellent and oft-used demonstration of the energy potential of the Higgs Mechanism. Or then again, perhaps it is simply because physicists thought that finally finding this shy particle would call for some of the bubbly.

On the other hand, some science writers and scientists can appreciate the ‘educational benefits’ of such a mysterious and controversial name because it attracts the attention of the general public and puts a relatable face on an extremely esoteric physics concept. Krusberg herself admits that “People are naturally drawn to the mysterious and the controversial, providing educators with great teaching opportunities.” But she worries about the larger social implications involved in “mixing the vernacular of physics and spirituality,” not least because such uncritical mixing can lead the non-scientific community to draw conclusions about the authority and reach of science that are not justified.

Understanding that the Higgs boson is not the literal stuff of God and that it does not prove or disprove God’s existence (as the name seems to suggest) extinguishes the fire under any sort of religious outcry. But this does not mean that its discovery is irrelevant to the discussion of science and faith, nor to the Christian community as a whole. As Dr. Krusberg remarks, “The recent discovery of [this] new boson at the LHC perfectly embodies the scientific process at its best (and thereby illustrates to the public why and how science works).” Scientific exploration of nature is not a fool-proof endeavor; healthy skepticism and accountability to a wide community of other researchers are absolutely critical to its success. But such evidence of the power and finesse of well-executed science as we saw last week is a testament to our ability to explore and understand the ‘how’ of the universe. God has equipped humanity with the desire, the intellectual abilities, and the collective will to recognize and explore the cosmic order and beauty of his creation. God has made our home knowable, and has given us the tools and capacities by which to know it.

It is valuable, then, for the Christian community to understand and appreciate how science works, in part to recognize that there are many instances in which science and the church work in tandem in order to better understand and better serve the world. But I think there is something else we can draw from the story of the Higgs boson, too. The nickname ‘the God particle’ has touched nerves in religious communities because it implies that science has the ability to prove or disprove divine existence by physical means. Even though the physics community is by no means claiming insight into the divine, it is sometimes assumed by the religious community that scientists view their work as chipping away at God’s existence when they begin to understand something that was previously unknown, or known only “by faith” in esoteric theories and models.

And yet, regardless of motives or metaphysical interpretations, perhaps physicists' search for the Higgs boson is in fact an apt picture of our own search for God. How many times have we stared up at the starry ceiling in times of crisis and prayed fervently for some kind of sign from God to assure us of his presence? And how many times has that much-desired evidence appeared only in retrospect, when we look back to see God’s hand faithfully and elegantly working in ways inscrutable at the time? It took a community of physicists to discern the presence of the Higgs boson. But even so, they could only do so after the fact from the cascade of particle decays it sparked; they could not observe the particle itself directly. In a similar way, though we often do not see the working of God directly, “in the moment,” we still trust in his presence and providence, often depending on friends, family and the community of the church to help us see his hand in hindsight.

So while the discovery of the Higgs boson does not itself explain God, we rejoice at the subtle yet striking new insight we have into God’s creative genius via the Higgs boson and at the way God gives evidence of his faithfulness in the ordered creation itself. Perhaps, however, the greatest insight we can glean from this breakthrough is an analogy for the way God calls us to seek him and find him together, in the community of those who follow his son.

Tomorrow, Baylor University physicist Gerald Cleaver answers the question, "What is the Higgs boson?"
