Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes. In my next post, we will look at some other biological processes that make use of—rather, depend on—randomness. This will set the stage for us to see that such processes can not only assemble a structure within seconds or minutes, but also generate complex, information-bearing molecules over billions of years. Even though the freedom inherent in nature sometimes produces unintelligently-designed structures (like viruses, which can kill us), we see that God has made, and continues to oversee by his providence, a good creation that, at least in part, is capable of creating itself.

Next weekend, we’ll continue this series about randomness and God’s divine will. Up next: how God created the body to heal itself, and how can random mutations can be both harmful and benign.

Genesis 8:1: But God remembered Noah and all the wild animals and all the domestic animals that were with him in the ark. And God made a wind blow over the earth, and the waters subsided; 2 the fountains of the deep and the windows of the heavens were closed, the rain from the heavens was restrained, 3 and the waters gradually receded from the earth.

The Flood narrative of Genesis 7-9 has played a prominent role in science and religion debates for over three hundred years and gave rise in earlier centuries to geological theories such as old earth catastrophism. While literary studies have uncovered the chiastic structure of the Flood story (see Gordon Wenham, “The Coherence of the Flood Narrative” Vetus Testamentum 28 (1978):336-48) and with it the theological pivot point of the entire narrative (Gen. 8:1 – “And God remembered Noah…), much of the popular attention remains on the questions regarding details (Is there THAT much water in the world to cover ALL the mountains to a depth of 15 cubits? Could you really fit two or seven of every animal species in an ark that size?)

Looking at a smaller matter, we find at the beginning and the middle of the narrative indications of an ancient Near Eastern worldview. As the story is told, the flood was not merely the result of excessive rain, but actually the convergence of the waters above the earth with the waters below the earth. It is, as one translation puts it, as if the sluice gates at the deep and of the heavens were thrown open and water poured in from above and below. This is a consistent picture from the Old Testament of a three-tiered universe—a dome above the earth holding back the heavenly waters, a flat earth with water on its surface, and water under an earth which is held up by pillars.

That the story is told using the cosmology of its time should not be unduly unsettling, nor that the story is reinterpreted as new understandings of the universe come into favor. By way of example, consider John Calvin and his understanding of the structure of the universe. Although committed to the principle of sola Scriptura, Calvin recognized that the Bible would have been written in terms its original recipients would have understood.

Calvin inherited the medieval cosmology of his time, a way of viewing the world heavily influenced by Greek thought and one which was about to receive shocks from astronomers such as Copernicus and Galileo. But not just yet. Calvin still subscribed to the common conception of his day in which the four elements—earth, air, fire, and water—comprised the earthly sphere and possessed unique characteristics. The nature of air and fire was to rise, while the nature of earth and water is to sink. Earth, being heavier than water, should sink to the center of the cosmos and water should compose the next layer. Both earth and water are spherical, i.e., naturally form spherically around the cosmic center. Thus the heavier spherical element of earth should be encased entirely within the lighter spherical element of water.

Notice what this does to the flood story. For Calvin, the amazing thing is that the world isn’t constantly under water and subject to flooding. In the cosmology of Calvin’s day, it does not take an act of God to cause a universal flood, but rather an actively present and restraining hand of God to keep the waters back in everyday circumstances and make inundation by water something other than universal.

Obviously, Calvin was wrong. Or perhaps we should say that medieval cosmology was flawed and justifiably gave way to new conceptions of the universe. The answer is not to return to an ancient Near Eastern cosmology, but to reinterpret cautiously within new and better cosmologies and to pay closest attention to the text and the theology of scripture.

The geological and planetary sciences bring their own unique contributions and are of more interest than the latest expedition to discover the ark on Mt. Ararat. Is the flood story a universalization of a catastrophic regional event that burned itself into the psyche of ancient cultures in the Mediterranean basin? Various theories regarding a Black Sea venue for a catastrophic flood event are still in process of being sorted out. It’s intriguing. Or the question where the water on Planet Earth comes from? Was it always here as an emanation of vapors from the earth’s crust in its early formation, or has it accumulated over eons through the steady bombardment of earth by small, icy comets? It’s an intriguing scientific question that is in the midst of determination through testing.

Preaching Suggestions

When preaching on the story of the Flood, it is easy to get lost in the debates over particulars. As mentioned elsewhere, to tackle all the peripheral issues threatens to turn a sermon into a geology lecture. Other settings are better suited to addressing those questions, and those are best addressed open-endedly.

A brief explanation of ancient Near Eastern cosmology can be helpful to contextualize the story. If there are those who are tempted to think that a cosmology embedded in the Bible must be inspired and definitive, one can note that cosmology has changed by the New Testament. The Bible itself isn’t wed to a particular structure of the universe.

What is important is to keep the theology of the text front and center, and in that theology there are at least three non-negotiables from the flood narrative. First, human sin and violence threatens to undo a good creation (the flood is a de-creation event, a return of the waters mentioned in Genesis 1:2). Second, God remembers Noah, and never forgets his promises. Third, the end of the flood is a covenant with the whole earth regarding the stability and endurance of the natural order.

The story in Genesis is a story (full of the deepest suggestion) about a magic apple of knowledge; but in the developed doctrine [of the Fall] the inherent magic apple has quite dropped out of sight, and the story is simply one of disobedience. I have the deepest respect even for Pagan myths, still more for myths in Holy Scripture. I therefore do not doubt that the version which emphasises the magic apple, and brings together the trees of life and knowledge, contains a deeper and subtler truth than the version which makes the apple simply and solely a pledge of obedience. But I assume that the Holy Spirit would not have allowed the latter to grow up in the Church and win the assent of great doctors unless it also was true and useful so far as it went. It is this version which I am going to discuss, because, though I suspect the primitive version to be far more profound, I know that I, at any rate, cannot penetrate its profundities.¹

Whatever its theological profundities, though, Lewis is clear that Genesis 2-3 is probably not a straightforward narrative of historical events. “What exactly happened when Man fell, we do not know,” he later writes. “We have no idea in what particular act, or series of acts, the self-contradictory, impossible wish [to be our own masters] found expression. For all I can see, it might have concerned the literal eating of a fruit, but the question is of no consequence.”²

What, then, is of consequence for Lewis, we might ask? The real story of the Fall, says Lewis, is not the surface narrative about “the magic apple,” but rather what he refers to as “the developed doctrine” of the Fall, namely the doctrine of humankind’s depraved condition:

According to [the doctrine of the Fall], man is now a horror to God and to himself and a creature ill-adapted to the universe not because God made him so but because he has made himself so by the abuse of his free will. To my mind this is the sole function of the doctrine.³

The “sole function of the doctrine” for Lewis is to name the human condition for what it is, namely, shot through with corruption. Or, as Lewis put it in A Preface to “Paradise Lost,” “The Fall is simply and solely Disobedience—doing what you have been told not to do: and it results from Pride—from being too big for your boots, forgetting your place, thinking that you are God.” You might call this the “Mere Depravity” view of the Fall.

Throughout The Problem of Pain Lewis displays a remarkable degree of comfort with evolutionary theory, not least evolutionary accounts of human origins. A corollary of Lewis’s acceptance of evolutionary theory, of course, is that death pre-existed humanity. Lewis grasps this nettle in chapter IX of the book when he writes,

The origin of animal suffering could be traced, by earlier generations, to the Fall of man—the whole world was infected by the uncreated rebellion of Adam. This is now impossible, for we have good reason to believe that animals existed long before men. Carnivorousness, with all that it entails, is older than humanity.⁵

Here is not the place to go into Lewis’s postulation that Satan was responsible for animal predation. We need only note that he makes this suggestion precisely in order to show how a broadly Darwinian picture of natural history may be compatible with a broadly Christian view of the world. For some, severing the link between the Fall of man and death’s entry into the world, is anathema. But given Lewis’ mere depravity view of the Fall, this evolutionary understanding of natural history creates no real problem for Christian faith.

Moreover, for Lewis the evolutionary picture of the ascent of humankind presents no real objection to the Christian doctrine of the Fall, either:

Many people think that this proposition [that we are fallen creatures] has been proved false by modern science. “We now know,” it is said, “that so far from having fallen out of a primeval state of virtue and happiness, men have slowly risen from brutality and savagery.” There seems to me to be a complete confusion here…. If by saying that man rose from brutality you mean simply that man is physically descended from animals, I have no objection. But it does not follow that the further back you go the more brutal–in the sense of wicked or wretched–you will find man to be.⁶

Lewis goes on to note that the categories of virtue and vice simply do not apply to the animal kingdom–and therefore not to our pre-human ancestors either–because animals as such are not moral agents. Moreover, Prehistoric man is not to be presumed to be altogether reprobate simply on account of using only rudimentary tools, hunting and gathering, and the like. Primitivity ought not to be confused with sinfulness he argues. Thus, for Lewis, the discoveries of modern paleontology and archaeology can tell us nothing about when or whether our ancestors fell from a state of innocence, and so we are free to accept, as Lewis seems to have, man’s physical descent from animals without giving up the Christian doctrine of the Fall.

While Lewis may not have publically argued for the historicity of Adam and Eve, his private opinions might have been another matter. In his recent essay “Darwin in the Dock,” John G. West has argued that, regardless of what he said in print, Lewis privately “embraced the literal existence of Adam and Eve.”⁷ West chiefly bases his argument for Lewis’s private belief in a literal Adam and Eve on an anecdote involving one of Lewis’ Oxford colleagues, Helen Gardner, recounted in A.N. Wilson’s C.S. Lewis: A Biography.⁸ Upon being asked at a dinner party whom he would most like to meet after death, Lewis replied, “Oh, I have no difficulty in deciding…. I want to meet Adam.” Gardner, it is reported, replied by saying that “if there really were, historically, someone whom we could name as ‘the first man’, he would be a Neanderthal ape-like figure, whose conversation she could not conceive of finding interesting.”⁹ Lewis, we are told, gruffly responded, “I see we have a Darwinian in our midst” and never invited Gardner to dinner again.¹⁰

West takes this tense little interaction between Lewis and Gardner to indicate that Lewis’ belief in a literal historical Adam and Eve. However, it should be noted that such a conclusion seems somewhat overhasty in light of what Lewis says in The Problem of Pain, where he articulates a view rather similar to what Gardner said that evening:

I do not doubt that if the Paradisal man could now appear among us, we should regard him as an utter savage, a creature to be exploited or, at best, patronised. Only one or two, and those the holiest among us, would glance a second time at the naked, shaggy-bearded, slow spoken creature: but they, after a few minutes, would fall at his feet.¹¹

Given that Lewis actually believed what he wrote here, the difference between Lewis and Gardner seems not to have been either the question of “whether man is physically descended from animals” (which, as we have seen, Lewis was willing to grant) or the question of whether Paradisal man would be a “naked, shaggy-bearded, slow spoken creature,” a “Neanderthal ape-like figure.” Rather they differed over whether “Paradisal man,” as Lewis puts it, would have been someone, however primitive, to be revered, or whether, as Gardner seemed to believe, a mere brute. Taking Lewis’ written statements at face-value, it would appear that his irritation with Gardner owed less to her acceptance of evolution than it did to her dismissive presumption that our forebears were but dull savages.

Finally, it should be noted that Lewis was not even committed to the most basic element of a belief in a literal Adam and Eve, namely, that it was precisely two humans who fell and from whence our species came. He writes, “We do not know how many of these creatures God made, nor how long they continued in the Paradisal state. But sooner or later they fell.”¹² Lewis’s mere depravity view of the Fall and his belief in the mythical character of the Eden story gave him some latitude on the question of whether the Fall consisted of a historic first human pair going wrong at an easily identifiable moment. For Lewis, it was apparently quite possible that whole tribes of “Paradisal” Prehistoric humans could have gone about their business for generations—hunting, gathering, singing around the campfire, rearing children, painting in caves—before the spiritual and scientifically undetectable catastrophe of “the Fall” occurred. In other words, if Lewis were presented with the recent genomic evidence which suggests that our species arose from an initial population of several thousand rather than only two, it is doubtful that it would have flustered him. It simply makes no difference to Lewis’s argument how or how many humans initially “fell.” All that matters for Lewis is that God made humans (perhaps via evolution, perhaps not) and that we humans have gone quite wrong–so wrong, in fact, that it is beyond our powers to repair ourselves. Mere Christianity, for Lewis, does not logically depend on the historicity of the Adam and Eve story, but on the doctrine of our mere depravity.

In tomorrow's concluding post, we turn to C.S. Lewis' views on the compatibility of evolution and Christian faith.

This week we feature the third clip from the upcoming documentary “From the Dust”, directed by filmmaker Ryan Pettey. It is our sincere hope that, above all else, the film can become a focal point for some of the big questions that inevitably arise at the intersection of science and faith. We believe Ryan's work will inform faith and enrich discussion, and we feel that this week’s topic, the Fall, is of particular importance for Christians as we think through the ramifications of creation by evolutionary mechanisms.

To help foster such dialogue, we are once again including several discussion questions with this week’s clip. In the transcript below, you’ll find several prompts that are meant to help viewers dig deeper into the material being presented. Mouse over each highlighted region and a question will appear on the side. We encourage you to watch this video with your friends, your churches, your small groups and Sunday School classes, your pastors -- or anyone else for that matter – and take some time to discuss what is being said (and maybe even what isn’t). You may not all agree, but you will find yourselves engaged in fruitful and spirited conversation. And it is this kind of conversation that will help move the science and faith discussion forward.

The provided questions are just a few of the discussion questions that go with this transcript, and we'd be happy to send them to you to foster further conversation within your church or small group setting. If you’d like to see the questions, or if you have stories from your own small group discussions about the clip, we would love to hear from you at info@biologos.org.

Editor's Note: The full documentary is now available on DVD and Blu-ray. You can order the film here, and learn more about the project here.

“The Fall” Transcript

Dr. Jeff Schloss: “My friends and colleagues, who have concerns about evolutionary theory for theological reasons, are onto something, and one of them involves the Fall, the nature of the Fall, what it is. Even if it is a metaphor, it is a metaphor for something, and what is that something? And how would we make sense of that something in light of evolutionary theory? The other issue on this has been probably the most serious issue that not only Christians, but all theists who believe in a good and providential God have wrestled with, it is the problem of natural evil.”

Reverend Dr. Michael Lloyd: “The problem of evil is a real problem to religious faith. It was certainly the thing for Darwin himself. That is what made him question his faith, and I think rightly so. It does not look like the sort of system that a good and loving and benevolent God would have set up. Now, obviously that raises huge questions because we don’t see any evidence of a world that was harmonious. We only see evidence of a world that was at war with itself, and that obviously is the problem that Christian theologians face. For a long time I used to believe that the Genesis narratives paint a picture of a world completely at peace, completely harmonious until the human fall, and then something goes wrong. When I began to look at it more closely, I began to think that there is more to it than that. There is evidence from the text that things are already dislocated, already out of joint. For one thing, there is the serpent, and however you interpret the serpent, here is a bit of the created order that is actively talking against God, working against God—so there is already something that has gone wrong. Secondly, there is the command to fill the earth and subdue it. There is the suggestion that something needs to be subdued, something is not quite right that needs to be put right and humans beings are called to do that—to put it right. And thirdly, it is a garden. It is almost as if God has said, ‘Here is a little bit I have done for you, here is a little bit of order and harmony that I have done for you. Now you go and spread that order and that harmony throughout the rest of creation.’ The tragedy is, of course, that human beings don’t do that. Rather than put that right, they make it worse.”

Dr. Alister McGrath: “Clearly Scripture distinguishes humanity from the rest of creation by this idea of the image of God. And that is understood in a number of ways—one of which is relational. Human beings have this God-given capacity to be able to relate to God, which is simply not there for the rest of creation. How do we understand that phrase: the image of God? If we accept the narrative of biological evolution, we have to say that at some point humanity became sufficiently distinguished from the rest of the natural world to be able to have this relationship with God.”

Reverend Dr. Michael Lloyd: “If you have a very finely graded gas tap and you begin to turn it on, initially, there is not enough gas in the air for the gas to ignite. So, you turn it up some more, still nothing, a bit more, still nothing, and a bit more, still nothing. At a particular point, there will be enough gas to air ratio for the thing to ignite. So, you can have a completely smooth, upward development, and yet, you can have something decisive happening at a particular moment. You get an increase in that moral capacity and moral awareness; you get an increase in their relational ability, in their social ability. You get an increase in their tool-making ability. You get an increase in their language. At a particular point there is enough of all that. There is enough relational capacity; there is enough social capacity and moral awareness and spiritual awareness for God to deal with us in a new way: ‘They have enough creativity to reflect the fact that I am the creator. They have enough relational capacity to reflect the fact that I am love. This in some way reflects who I am, and I will stamp my image upon them.’”

Reverend Dr. John Polkinghorne: “As hominids evolved and became more complex, then self-consciousness, in the sense of projecting our minds into the remote future or past began to dawn in them. And that didn’t bring biological death into the world, because obviously it had been there for millions of years beforehand, but it brought into the world what you might call mortality. Because our ancestors were self-conscious, they knew they were going to die. Because they had turned away from God, they had alienated themselves to the only one who was the ground for the hope of a destiny beyond death. And so, mortality, meaning the sadness, the human sadness at transiency and decay dawned in human life. Another very subtle feature of the Genesis 3 story is that it is a fall upwards as people would sometimes say. It is the gaining of some knowledge, the knowledge of good and evil, the story says. And so, the dawning of self-consciousness is also the gaining of something that wasn’t there before. What the serpent whispers in Eve’s ear is, ‘eat this fruit, and you will be like God. You won’t need God anymore. You can do it yourself.’ That is the fundamental sin, the fundamental mistake in human life is believing that we can do it on our own, doing it my way, and spiritual death is to deliberately and persistently cut yourself off from that. It doesn’t occur as an angry God giving you a punishment for not falling into line. It is simply that you have punished yourself. You know, preachers sometimes say that the gates of hell are locked from the inside not to keep the creatures in, but to keep God out. And that, I think in the end, is what spiritual death is if you persist in it. But God is always, I am sure, at work, seeking to draw people back into the divine love. I think that is the work that is necessary to understand what Paul is getting at in Romans 5 when he says that death came into the world through one man. The cost of development is a degree of precariousness. The people need the grace of God if we truly are to live fulfilling lives.”

Dr. Thompson responded that while the essence of Sin is ultimately mysterious, he suggests that there are some ways to think about Sin in the language of interpersonal neurobiology.

On the other hand, Dr. Smith found the wisdom of St. Augustine in The Confessions quite helpful—The essence of Sin is loving the wrong things in the wrong ways. It’s a disordered love.

We need to have an account of Sin in terms of habit. A lot of Christians today think of “sins” and discreet choices, but historically Christians have thought of Sin as a habitual tendency and disordering. It is formed over time—that’s what a vice is. Virtue and sanctification require ongoing re-habituation, a counter-formation of our inclinations.

Dr. Thompson followed up with a reference to Malcolm Gladwell’s Outliers and noted that people who are really good at what they do generally acquire it through lots of practice. Thompson then asked the audience, “How are we, in an embodied way, going to practice Christianity for 10,000 hours?”

So today we’ll conclude our “implications” section by returning to creational theology, and then turn to the ways TEs re-think Adam and Eve in light of human evolution. Some implications and conclusions of Theistic Evolution—continued again

Last time I introduced the idea that a Christocentric theology of creation is one of the hallmarks of Theistic Evolution, and I focused on the idea of the “Crucified God.” But the scientist-theologians who write about TE also think about creation and theodicy in terms of divine “kenosis” and eschatology. So today we’ll conclude our “implications” section by returning to creational theology, and then turn to the ways TEs re-think Adam and Eve in light of human evolution.

Kenosis, theodicy and eschatology

John Polkinghorne and others, citing Philippians 2:7, like to speak about divine “kenosis”, God’s choice to “empty himself” in taking on human form; they apply this also to the act of creating the world in a great work of self-sacrificial love. Although Wikipedia gives much information about the roots of this doctrine in Orthodox and Catholic circles, my knowledge is minimal and I cannot confirm what I find there (though it might all be correct). According to a theologian I once consulted, kenosis in soteriology was discussed by Lutherans in the 17th century (if not perhaps even earlier, by others), but was only extended to theology of creation in recent decades. The most I can say with confidence is this: one of the most striking features of Protestant thought about nature, during and since the Scientific Revolution, is the degree to which it is not Christocentric in the sense we are now discussing. In much Protestant and Evangelical literature devoted to the topic of creation, one often looks in vain even for references to Jesus, let alone to Jesus as the suffering servant through whom the world was made,. Only in the latter part of the 20th century do I find a clear emphasis on the idea that nature is the creation of the God who put aside power and was crucified. If this understanding is correct, then I would say that it’s high time, and let’s get on with it!

TEs (especially Polkinghorne) are also in the forefront of those Christian writers who are linking theodicy inextricably with eschatology. Yet another scientist-theologian, Robert Russell, offers this powerful eschatological vision in Cosmology From Alpha to Omega, drawing on all of the main ideas I’ve presented in this section:

[I]n order to move us beyond mere kenosis to genuine eschatology, I believe that both kenotic theology and eschatology must be structured on a trinitarian doctrine of God. The reason here is simple: it is the trinitarian God who will act to bring about the redemption of all of nature since it is this God who is revealed as God in and through the cross and resurrection of Jesus. A kenotic theodicy (that God suffers voluntarily with the world) in and of itself is not redemptive. Eschatology is required, in which the Father who suffers the death of the Son acts anew at Easter to raise Jesus from the dead. In turn, the involuntary suffering of all of nature--each species and each individual creature--must be taken up into the voluntary suffering of Christ on the cross (theopassionism) and through it the voluntary suffering of the Father (patripassionism).(p. 266)

George MacDonald (source)

Because this series is primarily focused on the history of approaches to understanding Science and the Bible, I will not delve more deeply into these important theological issues, but only direct readers to resources such as these. Still, I close this section with a quotation from George MacDonald’s Unspoken Sermons, the same passage that C. S. Lewis used in abbreviated form as an epigram for The Problem of Pain:

“the Son of God, who, instead of accepting the sacrifice of one of his creatures to satisfy his justice or support his dignity, gave himself utterly unto them, and therein to the Father by doing his lovely will; who suffered unto the death, not that men might not suffer, but that their suffering might be like his, and lead them up to his perfection...”

Adam, the fall, and sin

(5) TEs have to confront questions about human origins that are much easier for OECs or YECs to answer: Did Adam and Eve really exist as historical persons? Was the “fall” an actual historical event? If not, what is the origin of sin?

My comments here are much briefer, but I don’t mean to imply that the questions are any less important than the one I’ve just dealt with. Polkinghorne does not hold a traditional view of the fall, but he likes Reinhold Niebuhr’s view “that original sin is the only empirically verifiable Christian doctrine!” (Belief in God in an Age of Science, p. 88) This reminds me of G. K. Chesterton, who famously remarked, “Certain new theologians dispute original sin, which is the only part of Christian theology which can really be proved” (Orthodoxy, chap. 2). In other words, anyone who doubts the idea that we are “fallen” creatures simply needs to look around—that is all the evidence of our strong bent to wickedness that you’ll ever need.

There are ways to finesse the fall and evolution in a quasi-concordistic manner, such as the “headship” model advocated by Denis Alexander. Others reject any appeal to Concordism, stressing the principle of divine accommodation. For example, Denis Lamoureux argues that in the revelatory process the Holy Spirit came down to the level of understanding of the ancient Hebrews and used their ancient conception of de novo creation, in which humans were created quickly and completely. Thus, in Genesis chapters 2 and 3, Adam and Eve are ancient vessels that deliver the inerrant spiritual truths that God created us and that we are sinners.

The views that have received the most attention among evangelicals, however, are probably those of biblical scholar Peter Enns, particularly his new book, The Evolution of Adam. Instead of trying to summarize them myself, I’ll link his discussion of “Mistakes in the Adam/Evolution Discussion”, since it parallels some of the content in the book. Also see his replies to some evangelical scholars who have been critical of the book.

One of the most original and thoughtful proposals I have seen comes from philosopher Robin Collins (for bibliographical information on this and the other works cited in the rest of this column, see below). Collins calls his model the “Historical/Ideal” view, because “the original state described in the Garden story represents an ideal state that was never realized,” showing “what an ideal relation with God would be like.” Adam and Eve represent every person who has ever lived, but they also represent “the first hominids, or group of hominids, who had the capacity for free choice and self-consciousness.” Just as the first hominids made sinful choices, so do we now, and original sin involves “the resulting bondage to sin and spiritual darkness that is inherited from our ancestors and generated by our own choices.” I can’t convey the subtlety and thoroughness of this account in a short space, so those who want to know more will have to read for themselves. Conveniently, Collins provides a link to a “near final version” of his paper on his web site. If someone wants to summarize his arguments in a few paragraphs below, it would be a real service to our “course.”

Problems with historicity

(6) Questions about the historicity of Adam & Eve are underscored by evolution, but they would still come up even if Darwin had never existed and no one had ever proposed that humans and other animals have common ancestors. The Bible places Adam & Eve in a Neolithic world, with cities and agriculture, whereas non-biological scientific evidence shows that humans existed for a very long time before cities or agriculture came into existence.

Read that again. It’s a crucial point. Far too many people believe—erroneously—that evolution is responsible for undermining the historicity of Adam, Eve, and the Garden of Eden. In fact, the relevant science here is almost entirely from anthropology, not biology, and it involves human antiquity, not common ancestry. Since the mid-nineteenth century, evidence has been building that creatures anatomically and behaviorally identical to us have been on this planet for a very long time, far longer than the biblical 6,000 years. We could leave Darwin and evolution entirely out of the picture, and we would still be having a conversation about the historicity of Genesis 2 and 3. The same issues pertain to any OEC scenario. Most proponents of ID can’t duck this, either, even though they get to say “officially” that ID isn’t about the Bible. Because most ID proponents are not YECs, they accept the general validity of the methods used to date rocks and fossils, and so (by implication) this is their problem, too, whether or not it’s acknowledged.

To illustrate my point historically, let me introduce readers to George Frederick Wright (read more here and here). Ronald Numbers, the leading historian of American religion and science, wrote a clear, detailed article about this (see the reference below) that I strongly recommend to anyone who’s interest has been piqued. An influential Congregationalist clergyman and theologian, Wright was mentored by Harvard botanist Asa Gray, served briefly under Thomas C. Chamberlin on the U. S. Geological Survey, and even contributed articles on early humans and the ice age—his specialty—to scientific journals. During the 1870s, he worked closely with Gray to promote what is usually seen as a type of Theistic Evolution. By the early twentieth century, however, he appeared in some of his writings to have almost completely reversed his views on evolution. He even contributed an essay on “The Passing of Evolution” to the famous pamphlets, The Fundamentals, that later gave its name to that movement.

In other writings, however, Wright seemed to remain convinced of evolution, at one point saying that, “it is difficult to resist the conclusion that, so far as his physical organism is concerned, man is genetically connected with the highest order of the Mammalia.” Whatever he really thought about common ancestry—whether he was really a TE, an OEC, or an ID (one could make a good case for each)—the question of human antiquity dogged Wright for decades, as he sought ways to reconcile the genealogies in Genesis with accumulating evidence that humans have existed much longer than 6,000 years. Fortunately for Wright’s Christian faith, which probably hung in the balance, the famous Princeton theologian Benjamin Breckenridge Warfield, together with the conservative biblical scholar William Henry Green, managed to persuade Wright that the Genesis genealogies had plenty of wiggle room. Anyone wanting to see the crucial details should read Green’s paper on “Primeval Chronology” at this point. Note Warfield’s own conclusion (same URL): “There is no reason inherent in the nature of the Scriptural genealogies why a genealogy of ten recorded links, as each of those in Genesis v. and xi. is, may not represent an actual descent of a hundred or a thousand or ten thousand links.”

Can this really be true, without straining the whole idea of historicity? Davis Young’s skepticism seems appropriate here. How far back can we place Adam and Eve and still have contact with the biblical period? In my opinion, a clear and convincing picture of an historical Adam and Eve, reconciling the biblical picture with human antiquity, has not yet been produced, and I am doubtful that we will ever have one. Those who want more information about the possibilities and the difficulties are invited to consult the articles (cited below) by anthropologist James Hurd, evolutionary biologist David Wilcox, and anthropologist Dean Arnold. To the best of my knowledge, Hurd and Wilcox are TEs, while Arnold is an OEC. It’s up to you, my “students,” to consult these sources and place summaries and comments below. I’ve done enough already.

Looking Ahead

In about two weeks, I’ll conclude with a short history of Theistic Evolution. There’s plenty to think about in the interval. Please follow some of these links, borrow some of these books, and add your views to mine.

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!

In my previous essay, I discussed “Darwin’s finches” and how surprisingly little Charles Darwin himself had to say about them. In fact, it was actually the British ornithologist David Lack (1910-1973) who conducted the critical research that immortalized the finches in biology textbooks and popular lore. In 1973, the eminent German zoologist Ernst Mayr wrote:

Already well known among professional ornithologists, his work on the Galapagos finches gave David Lack world fame… There is no modern textbook of zoology, evolution or ecology which does not include an account of his work.¹

Ernst W. Mayr

Decades have passed since Mayr wrote these words, and David Lack’s name has largely faded from public discourse. On the other hand, the Galapagos finches have become one of the most recognized symbols of evolution in the world today. Does it really matter whether Lack or Darwin gets credit for describing the evolution of these remarkable birds?

Insofar as evolutionary theory contrasted with religious belief, it makes a big difference. In a culture that is eager to equate evolution with atheism, it should come as no surprise that these birds are only known as “Darwin’s finches”. Darwin’s personal struggles and ultimate rejection of Christianity are well documented, and people are eager to link his loss of faith to his evolutionary theory. David Lack, on the other hand, began his scientific career as an agnostic, but shortly after publishing his famous book on the evolution of Galápagos finches, he converted to Christianity! ²

A Christian at the forefront of evolutionary biology

Lack’s Christian conversion did not mark the end of his scientific achievements, either. In fact, he continued as a prolific researcher until just weeks before he died. Among his many achievements, he was Director of the Edward Grey Institute of Field Ornithology (1945-1973), Fellow of the Royal Society, and President of both the International Ornithological Congress (1962-66) and the British Ecological Society (1964-65). His fellow scientists held him in great esteem:

He was described as one of the most outstanding among world ornithologists; he was certainly this, but he was also one of the world’s leading evolutionists. All the time one saw developing his use of birds as material for the study of wider, deeper, biological problems.³

David Lack at the International Ornithological Congress, 1962.

Clearly David Lack was an outstanding scientist, and his commitment to Christianity did not tarnish, hinder, or undermine his research on evolution. But we might also ask, what was Lack like as a Christian? Did he keep his faith hidden from view, afraid that it might compromise his reputation as a scientist? Ernst Mayr, who interacted with David Lack professionally and personally for nearly 40 years, had this to say:

I have known only few people with such deep moral convictions as David Lack. He applied very high standards to his own work and was not inclined to condone shoddiness, superficiality and lack of sincerity in others. This did not always go well with those who preferred to compromise in favour of temporary expediency. David had been raised in an environment in which great stress was layed on moral principles and this attitude was later reinforced by his Christian faith. This explains his extraordinary unselfishness and modesty, and his great devotion to his family, to his students, to his friends, and to all the things that he lived for. The equanimity, indeed serenity, with which he faced death after his terminal cancer had been diagnosed is further evidence of the strength which his faith gave him.⁴

Like Asa Gray⁵ before him, and Francis Collins⁶ after, David Lack was an sincere, devout Christian, as well as a leading scientist who employed evolutionary theory to make brilliant discoveries about the natural world. Though Lack did not see any conflict between his scientific and Christian beliefs, he was sympathetic to the concerns of his fellow Christians. Therefore, ten years after publishing his masterpiece on Darwin’s Finches, Lack wrote another book entitled Evolutionary Theory and Christian Belief: The Unresolved Conflict.

Originally published in 1957, this book deals with the very same science and faith questions that Christians struggle with today— topics like randomness and chance, death in nature, miracles, and evolutionary ethics. While it would be unreasonable to expect anyone to completely resolve these matters, Lack offered numerous insights both as a devout Christian and one of the world’s leading biologists.

Let’s take a brief look at how Lack addressed some of these questions.

Blind Chance or Divine Plan?

Evolutionary theory does not invoke supernatural forces in explaining the history of life on Earth; instead, it relies on naturally-occurring processes to account for the vast diversity of life. Additionally, it explains animal behavior largely in terms of survival and reproduction, without appealing to any higher purpose of life. Taken together, does this imply that God is absent, and that our lives are ultimately meaningless?

David Lack responded,

Behind the criticism that Darwinism means that evolution is either random or rigidly determined lies the fear that evolution proceeds blindly, and not in accordance with a divine plan. This is another problem that really lies outside the terms of reference of biology. It is true that biologists have inferred that, because evolution occurs by natural selection, there is no divine plan; but they are being as illogical as those theologians whom they rightly criticize for inferring that, because there is a divine plan, evolution cannot be the result of natural selection.⁷

When rendering judgment on the ultimate meaning of life, biologists are speaking from their person beliefs, not from scientific authority. Moreover, Lack pointed out that many science enthusiasts have employed the concept of “randomness” in ambiguous and misleading ways:

Mutations are random in relation to the needs of the animal, but natural selection is not. Selection, as the word implies, is the reverse of chance.⁸

In support of his view, Lack pointed out that convergent evolution has produced uncanny resemblances between distantly-related species across the world, notably among marsupials in Australia. Different evolutionary trajectories can lead to very similar results.⁹

Death in Nature

After addressing concerns about the seeming “randomness” of evolution, Lack turned to another great concern, the role of death in natural selection:

Various writers–some Christian and others agnostic–have been troubled about natural selection not only because it seems too random, but also because it is so unpleasant.¹⁰

Genetic mutations are generally harmful, and for evolution by natural selection to produce new forms of life, an awful lot of organisms must die. For many Christians, it is inconceivable that a loving and merciful God would allow death on such a vast scale.

But Lack also pointed out that rejecting evolutionary theory doesn’t actually get rid of the problem of death. Regardless of what we think about evolution, the brute fact of mass extinction remains. Fossils of innumerable animals, plants, and microorganisms clearly demonstrate that the vast majority of species that have ever lived are now dead. It may be quite troubling for us to observe that our planet is a giant graveyard of natural history, but rejecting evolution will not change this fact.

Some Christians conclude that death could not have been part of the divine plan; instead, it must be the work of the devil, or the result of human sin. But this interpretation contains an implicit assumption that death is always evil. Is this really true? David Lack offered two intriguing insights:

courtship, seen in Basai, Gurgaon, India.

1. For a population to maintain a stable size, all births must be balanced by a corresponding number of deaths. A world in which no animals die is a world in which no animals are born. That means no reproduction, no courtship, and by implication, no singing birds—much to the dismay of ornithologists and people in love!

2. Some people, taking cues from Isaiah 11:6-7, suppose that in a perfect world, animals only eat plants. But in fact, plants themselves depend on the bacterial decay of dead organisms. If animals didn't die, then essential nutrients would disappear from the ground, and plants could not continue to grow. Eventually, there would be nothing left for animals to eat, and all life would cease.¹¹

Miracles

Many Christians are uncomfortable with evolutionary theory because it denies a miraculous, supernatural origin of life. They fear that if those miracles are denied, it might lead people to reject the possibility of miracles altogether, including the central feature of the Christian faith—the resurrection of Jesus from the dead.

As a devout Christian, David Lack certainly affirmed the fundamental tenets of the gospel. But at the same time, he explained to his readers that invoking miracles to account for unusual features of the natural world is not particularly helpful when trying to deepen our understanding of God’s great multitude of creatures:

[The biologist's] research depends on repeated observations. It need not, as popularly supposed, consist solely, or even mainly of measurements and experiments, but unless events are repeated, they cannot be assessed by science. Hence truly unique events come outside the domain of science, though biologists are not usually convinced when told they must, therefore, leave such problems as miracles to others. For one of the chief ways in which research has advanced is through the discovery of apparent exceptions to the known rules, and if further study shows the exceptions to be replicable, new regularities are revealed from which modified rules can be propounded. This method has been so successful that the biologist tends to doubt whether there are any types of irregularity, or seeming irregularity, that will not yield to it.¹²

But just because a scientist cannot repeat a particular event doesn’t mean it didn’t happen. Both natural history and human history contain unique events that only happened once. As we peer into the past, the difficulty of discerning fact from fiction inspires us to further investigate the mysteries that surround us.

Conclusion

David Lack’s book Evolutionary Theory and Christian Belief was quite insightful, but his enduring achievements took place in evolutionary biology, a place where many Christians are afraid to tread. While it is significant that he himself found no contradiction between his faith and his science, perhaps the greatest testament to the compatibility between Christian faith and evolution is the life he led as a believer in both. As we saw in Ernst Mayr’s candid praise, Lack reflected the light of Christ through both his personal and his professional relationships.

Today, many voices in our culture still insist that evolution is incompatible with a sincere faith in Jesus, but a careful look at history demonstrates otherwise. In the future, perhaps more people of faith will have confidence to study biology knowing that one of the most iconic symbols of evolution—the Galapagos finches—owe their fame in large part to a devout Christian named David Lack.

Author's Note

I am so thankful that I grew up in a Christian environment, which both kindled and nurtured my relationship with Jesus Christ. The Biblical instruction I received from my parents, pastors, and teachers has been invaluable as I walk out my love for the Lord from day to day. However, there was one specific topic growing up which was not fully addressed, namely evolutionary theory.

Coming from a conservative Christian background, evolution was given little or no thought because of its seeming contradiction to the creation story in Genesis. To me, evolution meant a monkey became a human, and as far as I knew, I had never seen that happen! So, of course, it appeared too improbable to hold any truth. When it was discussed, an inadequate picture of its ideas was often painted, which caused immediate suspicion and rejection of the theory. I don’t think this was intentional, but most Christians have never learned an unbiased, in-depth theory of evolution that is completely detached from societal agendas and philosophical conclusions. Therefore, their explanations of the theory are often misinformed.

My senior year of high school, I took AP Biology, and finally learned the scientific reasoning supporting this theory. I was surprised by how logical and obvious the mechanisms of change (such as mutations, natural selection, genetic drift, and so on) were that gave rise to new species. My subsequent response was, “No wonder people believe evolution occurred.” At that point, I was convinced that microevolution (evolution within a species) existed, but I was still questioning macroevolution.

Now, being at Point Loma Nazarene University as an undergrad in the Biology-Chemistry major and a year-round, student intern at BioLogos, my understanding of evolution has expanded enormously. I have enjoyed critically thinking through the evidence for evolution and reading articles that tackle difficult issues at the interface of science and Christian faith. Ultimately, I know that God has created all things, but the processes he used surpass my small understanding.

My personal wrestling with evolution and quest for truth has led to times of prayer and studying God’s Word, which has deepened my love for him in ways I cannot express. The first chapters of Genesis, in particular, have come alive. My whole life, the creation story was a straightforward list of facts about the creation of the world; I never searched further. I didn’t even perceive the truths Genesis declared over my very identity and God’s character. The more I study his Word and handiwork, I glimpse the awesomeness and majesty of the Creator, who loves me much more than I know. There is still so much to learn, but I am confident that he will lead me into all truth as I seek him out.

I desire to give others the opportunity to see evolution accurately and to distinguish it from the traditional, philosophical, and personal conclusions that too often cloud the scientific theory. I believe these conclusions alienate Christians from evolution more than the scientific theory itself. Ultimately, I do not mean to convince someone about evolution, but simply to give them the freedom to understand it.

Therefore, my goal for this podcast is two-fold:

• First, to offer a new perspective on randomness within natural processes that removes its negative connotations (especially as it relates to evolution).
• Second, to expose why evolution is powerless to support conclusions beyond the physical realm.

This will hopefully encourage others to study evolutionary theory and draw their own conclusions about its meaning in the framework of their faith.

Many of the games I enjoyed playing involve a combination of strategy and randomness: card games of various sorts, backgammon, and board games like Monopoly and Parcheesi. Some games that rely exclusively on chance (like War and Candy Land) or too heavily on chance (like Sorry) quickly became uninteresting to me. In fact, for Sorry, War, and several other games, I introduced additional rules to change the balance of strategy and luck—for example, by allowing each player to hold a hand of cards rather than merely flip a card and follow its bidding.

When my children were young, I played many games with them, especially those involving some amount of chance. I always play to win, so games of pure strategy like chess gave me too great an advantage—at least when they were still young. I still remember the first time I played the German game Mitternachtspartie with my children and some of their cousins. The game uses a die on which the number 5 has been replaced with the image of Hugo the ghost. Each player rolls the die and moves one of his figures the specified number of squares, unless Hugo is rolled, in which case Hugo moves instead.

I quickly worked out the expected distance Hugo would move for each of my turns and the expected number of squares I would get to move my own figures each turn. Using that information, I could strategically place my figures in the opening portion of the game. I fully expected to win this first game, since my young children were going to have to learn from experience what I already knew by the mathematics of probability. I lost—badly. As it turned out, the die had two Hugos on it. So compared to my expectations, Hugo moved twice as often, and my figures moved slightly less far. That combination turned the carefully calculated positioning of my figures into a disaster.

From Fun and Games to Science

I still enjoy playing games, including games that involve chance. But these days I encounter randomness even more often in my profession. I was trained as a mathematician and now work at the intersection of mathematics, statistics, and computer science. Like many scientists, I use randomness on a daily basis as part of our toolkit for modeling and investigating all sorts of phenomena. Models known as stochastic models, which explicitly incorporate random components, often via simulation in computer software, are used to model everything from diffusion to genetics to quantum mechanics. Insurance companies and financial institutions use stochastic models to manage risk. If we include all the applications of statistics, then almost no area of science is untouched by the use of randomness.

Most of the time, scientists and game players alike don’t devote much thought to just what makes randomness tick. But they both know that the better they understand the probabilities, the more successful they are. Nevertheless, if you ask many of them what it means for something to be random, they may struggle to put it into words. I won’t try to give a precise definition either, but it is important that we have some idea what we are talking about, so let’s consider one of the prototypical examples of randomness: the tossing of a fair coin.

If I flip a coin, the result could be heads or tails. Until I flip the coin, I don’t know which it will be. In this sense, the coin toss is unpredictable. If the coin is fair, each result is equally likely, so while I cannot say in advance whether a particular result will be heads or tails, I can say something about a large number of flips: approximately half should be heads and the other half tails.

A little mathematics even allows me to determine a range around 50% in which the percentage will almost surely lie. For example, if I flip a fair coin 1,000 times, the percentage of heads will most likely be between 45% and 55% (where “most likely” means a 99% chance). If the percentage of heads lies outside this range—especially if it is quite far outside this range—I am going to be suspicious that the coin flipping process is not fair. That’s one of the key ideas in statistics: not only can we calculate the frequency with which an event occurs, but we can compare data to a stochastic model to see if they are compatible or incompatible.

There are several interesting things we can learn by considering a coin toss. First, probability calculations rely on assumptions. If the assumptions are incorrect, then the probability calculations will also be incorrect. For example, if the coin is biased (such as one that is heads 60% of the time), but we assume it is fair, then the probability calculations given above will be wrong. Of course, if the assumptions are not too far from correct, the results may still be sufficiently accurate for scientific conclusions. If we have an appropriate way to collect data, then we can test our assumptions by comparing data to projections made based on the assumptions.

Second, “random” does not imply “equally likely.” A fair coin should have equal probabilities of heads or tails, but a biased coin is no less random. It’s just different. It is not as simple to handle arithmetically as a situation in which all outcomes are equally likely, but it is not otherwise special. It is a common mistake to assume random events are equally likely when they are not (or when that assumption is not justified).

Third, randomness is about the process. It is a fun experiment to flip a penny 100 times, then spin a penny 100 times and record the side that is showing when it finally tips over, then to stand the penny on end (this takes a steady hand and a little practice) and record which side is showing after pounding the table. These are three different processes, and they do not yield the same results.

Fourth, random processes produce patterns. I sometimes ask my students to mentally flip a coin and record the results as a sequence of letters (e.g., “HTTHHTHT”). Then I have them actually flip a coin and record the results. If the sequences are long enough, I can almost always tell them which is which. The sequences imagined by the students tend to have too few runs of consecutive heads or tails. The sequences based on real coin flips usually include several heads in a row. People not familiar with randomness are often surprised at the patterns that result and assume that the process must not have been random when they perceive a pattern. Our eyes and minds are drawn to similarities and patterns—even those that are produced purely randomly. This can lead us to draw false conclusions from coincidences of all sorts.

Consider the image in Figure 1. It was constructed using a computer to randomly throw 300 darts at a square board. Every position on the board was equally likely to be hit by a dart. This does not, however, mean that the dots are evenly spaced. There are 100 smaller squares. The average is three dots per square. But your eye is likely drawn to some clusters and voids. My eye also catches a graceful downward swoop in the lower part of the upper left quarter. All of this is exactly what we should expect from this random process. If we repeated this experiment, we should expect similar results. Several of the smaller squares would be empty and some others would have two or three times the average number of dots, but these clusters and voids would appear in different places.

Finally, randomness can be used to produce patterns intentionally. Consider the two pictures in Figure 2. You may think the two pictures are identical, but they are not. However, they were each constructed using the same random process:

1. Start at the lower left corner of the big triangle.
2. Randomly choose one of the three corners of the big triangle.
3. Move half way to that corner, placing a dot at the new location.
4. Repeat steps 2 and 3, 50,000 times.

The first few steps of this process for each image are illustrated in Figure 3. Although the final images look very similar, the route taken to get there is very different. In fact, the only point the two images have in common is the starting point. As the creator of the program that generated these images, I knew full well that the result would resemble a fractal image known to mathematicians as Sierpinski’s Triangle, even though I did not know or exercise any control over how the individual points would be selected.

Despite our familiarity with children’s games and the importance of stochastic models throughout the sciences, many Christians have a reaction to randomness that falls somewhere between uneasy and antagonistic. And yet, those same Christians may well watch the evening news to learn about public opinion polls forecasting upcoming elections, take prescription drugs approved by the FDA based on statistics found in clinical trials, obtain electrical power from a nuclear power plant that uses random fission reactions, and insure their cars with companies that rely on stochastic models to set the rates. The foundation of each of these activities is a thorough understanding of randomness that begins with the simple description above.

So where does the uneasiness come from? Likely it comes from the feeling that taking randomness seriously means not taking God seriously. Or put more strongly, it comes from a fear that believing in randomness means not believing in God. Next week we’ll address that problem by asking the question, “Could God use randomness to achieve his purposes?”

In the 1950s, Cage began using various methods of “casting lots” to determine how elements of his music would be chosen and arranged—principally the Chinese system of I Ching. His controversial program was to distance himself from his own creative process, and he explored many additional strategies to transform the role of “creator” into one of “observer.” Most famous of these was his musical composition, “4.33,” which consisted of a pianist sitting at the instrument doing nothing at all for four minutes and thirty-three seconds, while musician and audience listened to the ambient sounds of the concert hall. Yet contrary to that main thrust of Cage’s work, a description of the activities during the week-long residency at the Mountain Lake Workshop where the New River Watercolor Series were made suggests that choice, constraint, and intention were integral and inescapable tools in putting randomness to work for creative ends.

Here’s art historian and theorist Howard Risatti’s description of Cage’s plan of action for the New River Watercolors, from the website of artist Ray Kass, who runs the Mountain Lake program and was Cage’s collaborator for his work there:

Following upon [a previous (1983) Mountain Lake workshop] “painting experiment,” stones collected from the New River were sorted into three groups according to size, which were separately numbered; numerous and varied brushes were divided into two separately numbered groups; likewise, feathers to paint with, colors and washes, and papers were also divided and numbered. In this way, chance procedures using pages of random numbers that were now generated by a computer program could be used to determine the specific materials utilized for each painting (e.g., which painting instruments, what type of paper and which colors, how many washes, which stones to paint around, where to locate the stones on the paper).

While this list enumerates all the specific variables that Cage and his team submitted to chance, there was an incredible level of personal engagement with the materials: Cage didn’t just show us drawings of where the I Ching said the rocks ought to be, he (or his assistants) placed them on the paper and used them as guides to paint around. Large custom brushes were constructed to lay on washes of color, and even the paints were hand mixed, combined, and diluted according to his desires.

Cage’s use of chance, then, was not a “hands off” process, but neither was it a matter of total control: Cage selected processes to create a space of play between himself and the materials he used: the feather between himself and the paper, for instance, introduced variability of resistance and spring, its ability to hold paint, the width of the line. All of these things were elements of material ‘freedom,’ areas in which Cage asked the stuff he used to make the paintings to take part in the process—to contribute its own identity to the intentional, purposeful, and determined work of creating “based on chance.” This should not be surprising, as all art, all creation that we can observe, happens as a dialectic between materials and the creator, and such engagement and interaction in no way lessons the purpose of making, the end in sight.

Kass’ book The Sight of Silence: John Cage’s Complete Watercolors, gives a much more complete account of the tools, processes, and interpersonal reactions between Cage, Kass, and the team of student assistants who helped at almost every stage of the creation of the works. The book goes to great length to honor Cage’s ideal of being present in but not controlling the outcomes (not least by nearly always putting words like “choice” in quotation marks), but the description of his process makes the centrality of Cage’s personal aesthetic and artistic motives inescapable, even more than his physical engagement. What comes through perhaps even more than the way Cage intended to allow chance to ‘guide the creative process’ is that way Cage, himself, not only set the parameters of the chance he allowed into the system, not only engaged directly with the materials during the process, but also exercised judgment over the results, both in process and at the end:

“Cage decided he didn’t want the images of the stones to overlap or go off the sides of the paper. To guarantee this restriction, he created conditions and rules to limit their possible placements.” (p. 51)

“For this single painting [Series IV, #1, pictured above] Cage chose to confine the images of the rocks to a lower area of the paper that represented the proportion of the “golden rectangle. . .” (p. 57)

“While “choice” established much of the work’s nature, “chance” highlighted the intrinsic nature of the materials to reveal a refreshing presence.” (p. 59)

“[H]e initially decided to remove [the first painting of Series III] from the group, and then, liking it more, changed his mind and returned it to the group that would be signed.” (p. 56)

This last note is particularly interesting in that it highlights the fact that Cage was claiming these paintings, naming himself as their author, and was attentive to which ones he approved of enough to call his own. There is no way around the fact that Cage was subjectively as well as objectively the maker of these works: the author of the procedures by which they came to be, but well as the judge (and sometimes redeemer) of the results. For Cage, randomness was a tool, no different than the brushes or rocks or paints is that its specific parameters were chosen at the outset, and always used within the context of his over-arching vision. Perhaps we may likewise think of God’s use of chance—constrained by and tuned to the material conditions he established at the birth of the cosmos—as a way to both engage with and allow freedom for the creation itself.

With any work of art it is reasonable to ask, “Is it beautiful?” or more tellingly, “Would I hang this on my wall?” Seeing Cage’s watercolors for first time without any knowledge of the process or the relative fame of Cage himself, some might be intrigued by the structure of the work (the proportions of the golden rectangle, the overlapping stone shapes, the colors of the paint) while others would be completely uninterested, perhaps even after hearing about how they were made and seeing them in the context of the rest of the New River Watercolor series. But if you had been there in the shop as an assistant, or even observer, if you had been party to the relationships that developed even over the few days Cage spent at the Mountain Lake Workshop, your sense of the beauty of these paintings (and perhaps even scraps of paper Cage used to try out brushes or washes), would take on a different meaning, in much the way we treasure the crayon drawings of our children not because they are spectacular art, but because they are tokens of our relationship.

I make that observation to emphasize one other aspect of Cage’s creative process: that Cage was the instigator first and foremost of relationships of creation. His process created not only paintings but the fellowship that developed as the work was being done. That social, interpersonal dimension is what gives the objects a depth of meaning beyond their material composition, and suggests the particular roles humanity has been given by God. One role is to join into the creative process as lesser, but not unimportant co-creators with him; the other is to observe, recognize and celebrate his activity in the world. Where some will see randomness as evidence of an absent God, our knowledge of this most personal and participatory aspect of creation points us to the God who is with us.

With God’s creation as with human art, we may (or may not) marvel at any one particular “work,” or even think the specifics of how it was made are interesting or attractive; but knowledge of and fellowship with the artist transforms our appreciation of the process as well as its results. When we know the maker, we come to recognize and treasure even the most “random” bits of his handiwork, and name them as his, nonetheless.

Perusing the writings of atheistic scientists and philosophers like Daniel Dennett, one could easily get the impression that arriving at a simpler explanation for something equates to a revelation that things are “lower, cruder, and more trivial.” But at the heart of Barr’s critique is the observation that in fundamental physics and advanced mathematics, “simpler” does not mean more chaotic and inchoate, but rather more elegant and beautiful. Those who hold to a philosophical reductionism “overlook the hidden forces and principles” that govern the processes of cosmic evolution.

Barr’s article lays out the way that the work of scientists and mathematicians exploring the fundamental principles of physics (from Kepler to Einstein to those currently running the Large Hadron Collider in Switzerland) actually suggests “that order does not really emerge from chaos, as we might naively assume; it always emerges from greater and more impressive order already present at a deeper level.” This excerpt gives his first example, the starting point from which he guides us into strangely beautiful world of particle physics, and towards the discovery that “matter, although mindless itself, is the product of a Mind of infinite profundity and infinite simplicity.”

Fearful Symmetries

“Let’s start with a simple but instructive example of how order can appear to emerge spontaneously from mere chaos through the operation of natural forces. Imagine a large number of identical marbles rolling around randomly in a shoe box. If the box is tilted, all the marbles will roll down into a corner and arrange themselves into what is called the “hexagonal closest packing” pattern. (This is the same pattern one sees in oranges stacked on a fruit stand or in cells in a beehive.) This orderly structure emerges as the result of blind physical forces and mathematical laws. There is no hand arranging it. Physics requires the marbles to lower their gravitational potential energy as much as possible by squeezing down into the corner, which leads to the geometry of hexagonal packing.

At this point it seems as though order has indeed sprung from mere chaos. To see why this is wrong, however, consider a genuinely chaotic situation: a typical teenager’s bedroom. Imagine a huge jack tilting the bedroom so that everything in it slides into a corner. The result would not be an orderly pattern but instead a jumbled heap of lamps, furniture, books, clothing, and what have you.

Why the difference? Part of the answer is that, unlike the objects in the bedroom, the marbles in the box all have the same size and shape. But there’s more to it. Put a number of spoons of the same size and shape into a box and tilt it, and the result will be a jumbled heap. Marbles differ from spoons because their shape is spherical. When spoons tumble into a corner, they end up pointing every which way, but marbles don’t point every which way, because no matter which way a sphere is turned it looks exactly the same.

These two crucial features of the marbles—having the same shape and having a spherical shape—should be understood as principles of order that are already present in the supposedly chaotic situation before the box was tilted. In fact, the more we reduce to deeper explanations, the higher we go. This is because, in a sense that can be made mathematically precise, the preexisting order inherent in the marbles is greater than the order that emerges after the marbles arrange themselves. This requires some explanation.

Both the preexisting order and the order that emerges involve symmetry, a concept of central importance in modern physics, as we’ll see. Mathematicians and physicists have a peculiar way of thinking about symmetry: A symmetry is something that is done. For example, if one rotates a square by 90 degrees, it looks the same, so rotating by 90 degrees is said to be a symmetry of the square. So is rotating by 180 degrees, 270 degrees, or a full 360 degrees. A square thus has exactly four symmetries.

Not surprisingly, the hexagonal pattern the marbles form has six symmetries (rotating by any multiple of 60 degrees: 60, 120, 180, 240, 300, and 360 degrees). A sphere, on the other hand, has an infinite number of symmetries—doubly infinite, in fact, since rotating a sphere by any angle about any axis leaves it looking the same. And, what’s more, the symmetries of a sphere include all the symmetries of a hexagon.

If we think this way about symmetry, careful analysis shows that, when marbles arrange themselves into the hexagonal pattern, just six of the infinite number of symmetries in the shape of the marbles are ex-pressed or manifested in their final arrangement. The rest of the symmetries are said, in the jargon of physics, to be spontaneously broken. So, in the simple example of marbles in a tilted box, we can see that symmetry isn’t popping out of nowhere. It is being distilled out of a greater symmetry already present within the spherical shape of the marbles.”

In the full essay, Barr gives a richer description of how this most basic kind of symmetry is just one sort of order, and how even this form points to other much more complex kinds of symmetry whose properties may be described only through the tools of complex mathematics. As he says, “the symmetries that characterize the deepest laws of physics are mathematically richer and stranger than the ones we encounter in everyday life.” But even more important than the fact that such mathematical concepts exist and are beautiful, more important even than the way such esoteric mathematical symmetries have suggested imminently practical experimental projects, is the way they point to a universe that is anything but brutish and trivial, though its elegance may be hard to see:

“It is true that the cosmos was at one point a swirling mass of gas and dust out of which has come the extraordinary complexity of life as we experience it. Yet, at every moment in this process of development, a greater and more impressive order operates within—an order that did not develop but was there from the beginning. In the upper world, mind, thought, and ideas make their appearance as fruit on the topmost branches of an evolutionary tree. Below the surface, we see the taproots of reality, the fundamental laws of physics that shimmer with ideas of profound simplicity.”

I’d like to suggest that this argument is in significant ways misplaced. The participants in this debate all seem to agree that what makes us “human” can be defined by genes and population studies. There is a pressing need for them to conform theology to population genetics, or to conform population genetics to theology, because the story of our genes is implicitly equated with the story of what it means to be “human.” The hypothesis that there was a “first human” – a capital-A “Adam” – can be tested in our genes.

But “genes” do not make us “human.” What makes us “human” is the irreducible phenomena of all of our material and immaterial being as persons.

Nothing we observe in the universe is flat. By “flat” I mean having only one aspect or “layer.” Consider, for example, an apple. What is it? Is it the fruit of an apple tree? The seed-carrier – the potentiality – of new apple trees? Beautiful and delicious? Skin, flesh, and core? Water and organic molecules? Caloric energy and roughage? Hydrogen, oxygen, and carbon? Physical laws? All of these things comprise some of what we mean by “apple,” but none of them are what an “apple” is. The reality that is “apple” cannot be reduced to any one of its aspects or layers.

It is possible to think of these aspects or layers hierarchically, with “higher” layers that emerge from “lower” ones. Physical laws emerge from quantum probabilities; molecules emerge from physical laws; seeds, skin, flesh and core emerge from complex arrangements of molecules; beauty and delight emerge from the connection of skin, flesh and core to human sense perception;¹ “apple” emerges from all of this (and more) combined with the human cultural experience of this thing we call “apple.”

Notice that some “layers” can impinge or “supervene” on lower ones – for example, human sense perception and cultural experience do something to this thing confronting the subject in order for it to become “apple.” But notice also that “apple” is not merely a cultural construction. The word or signifier “apple,” of course, could be arbitrary, but there is an objective reality to the thing signified. The layer of human sense perception and cultural experience supervenes upon, but does not create, the lower-order reality from which it emerges.

Sociologist Christian Smith draws these strands together in a critical realist framework in his excellent book What Is a Person?: Rethinking Humanity, Social Life, and the Moral Good from the Person Up. In a critically realist approach to culture and human personhood, Smith suggests, “[h]uman beings do have an identifiable nature that is rooted in the natural world, although the character of human nature is such that it gives rise to capacities to construct variable meanings and identities….” Culture is a social construction, but it is not merely a social construction. Human beings are social, but they are not subsumed by the social. The reality we inhabit is “stratified”: it includes both the reality of individual conscious human agents and the reality of the social structures that emerge from the cultures created by those agents. These “personal” and “cultural” layers of the world interact with each other dynamically, each continually informing and changing the other.

Smith’s approach is helpful, but perhaps it does not go far enough. For Smith, as for critical realists in general, the phenomena of human culture remain subject to some degree of granular disaggregation, at least analytically. A phenomenological approach suggests that no “thing” can be broken into components and still comprise that “thing” – the genes that encode for apple trees are not apple seeds, apple seeds are not apple trees, and apple trees are not apples. The critical realist framework of stratification, emergence, and supervenience functions as a very useful heuristic device, but to describe what an apple is, we must approach the phenomenon of “apple” in its fullness. To know whether something falls into the kind “apple,” we must hold an ideal of everything an apple is, and compare the subject to the ideal.

And because of the transcendence of the ideal concept of “apple,” we can begin to speak of the relative excellence of particular instantiations of apples. What is an “excellent” apple? What distinguishes the excellent apple from a poor one? We can only ask such questions if “apple” means something more than the particular physical specimen in hand, whether firm, sweet and tart, or bruised and sour.

The same is true of human “persons.” We can say almost nothing about a “person” merely by observing genes, because genes are not “persons.” Populations genetics studies can provide models of the dispersion of genes through groups of biological entities, but they can tell us nothing whatsoever about when the first “human person” emerged. Indeed, for population genetics qua population genetics, there simply are no “persons” – for this is a science of the movement of genes, not a philosophical, sociological, or theological description of “persons.”

So what of “Adam?” It is often suggested that in Romans 5:12 Adam is a type of Christ. But, in fact, in Paul’s thought, as well as for the early Church Fathers, Christ is the type, the typos, a notion derived from the “stamp” or “seal” on an official document. There is a hint in Romans 5 of a truth that would only become clarified later in Christian theology – that the pre-incarnate Christ, the second person of the Trinity, always was. Whereas Arius declared that “there was a time when he [Christ] was not,” Nicea established the orthodox Christology of Christ’s eternal sonship. Thus Christ is and was the Redeemer, the one for whom creation was made and in whose death and resurrection creation always finds its fulfillment. Adam’s failure was that he went against type – he did not conform to Christ but rather tried to become something else, and thereby the true nature of humanity was broken.

Is the typos of Christ reducible to a set of genes? Surely not. It resides not in genes or in any other created thing but rather in the Triune life of God Himself. We might speak, in a roughly analogical way, of ideas we hold in our minds – say, the idea of a perfect Bordeaux, ruby-red, silky, smoky, plummy, luxurious. We could labor to instantiate that idea, combining genes and terroir and water and light and care, and perhaps we might achieve it, to the point where upon taking a sip we exclaim, “this – this – is Bordeaux. Nothing else is worthy of that name.”

This is what God said of Adam, when he gave him breath and a name. It is not something that God said of any other creature, even apparently some creatures that a modern population geneticist or paleoanthropologist might designate as ancestrally human based on genes or bones. Yet that Adam, and each of us in that Adam, fail to participate fully and unreservedly in the true nature of the true human, the nature of Christ. And so Pontius Pilot, an unwitting prophet, said of Christ: “behold, the man” (John 19:5, KJV). And so also Paul invites us to see: the sinful man, the broken seal, the first created Adam; and the true type, the seal of humanity’s future, the perfect Adam, the Christ. None of this is about the definitions and categories of modern science, as helpful and important as they may be for the progress of scientific thought. It is, rather, about the fullness of what it means to be human.

Notes

1. Human sense perception, of course, is an emergent property of an even more complex set of relations that give rise to the human “person.”

The song entitled “The Fall” by Gungor is from the artists’ latest album Ghosts Upon the Earth. The lyrics begin by painting a picture of the Fall as something in which each person has participated as indicated by the assertion that “the fruit (of the Fall of man) is seen in every eye and every hand.” After reflecting on the words, consider the discussion questions below.

“The Fall” by Gungor

The Fall, the Fall, Oh God, the Fall of man,
The fruit is found in every eye and every hand,
Nothing, there is nothing yet in truest form,
We walk like ghosts upon the Earth,
The ground it groans.

How long? How long will you wait?
How long? How long till you save us all, save us all?

Turn your face to me; turn your face to me.
Turn your face to me; turn your face to me.

The light, the light, the morning light is gone,
And all that is left is fragile breath and failing lungs.
The night, the night, the guiding night has come,
Uniting lover with his bride more precious than the dawn.

How long? How long must we wait?

Turn your face to me; turn your face to me.
Turn your face to me; turn your face to me.

Questions

1. By focusing only on the Fall as a historical event, have we consciously or unconsciously simplified it—almost removing ourselves from the story?

2. Besides Genesis 3, what other Scripture has inspired the opening lines of this song? Does the feeling evoked by these opening lines personalize that passage for you?

3. Have you ever felt: “the light, the light, the morning light is gone?” Have you experienced night as “guiding?” Who is the lover? What Scripture informs these lines?

4. Have you ever asked, “How long? How long?” Have you heard the answer, “Turn your face to me. Turn your face to me?”

5. Do you agree that the story of Adam and Eve is your story, except for one important difference? What is that difference for you?

Michael Gungor has also served as a pastor at the Bloom Church in Denver, Colorado. Below we post an excerpt from a sermon he has given on his own personal journey and his views about science and Scripture.

In today's video, Oxford physicist Ard Louis discusses the famous debate between renowned evolutionary biologists Stephen Jay Gould and Simon Conway Morris. Gould believed (and wrote in his book Wonderful Life) that if the "tape" of evolution were rerun, the chance that anything like human intelligence would emerge is essentially zero. In other words, humanity is here through random accident. Gould pointed to the work of Morris and fellow scientists in their research of the Burgess Shale as evidence for this view.

However, Morris himself disagrees, pointing to what is called evolutionary convergence. As Morris notes, there are numerous examples of identical features evolving multiple times throughout the history of life independently. Morris believes that if the tape of life were replayed, we would see something like humans emerge. A Christian might say, it looks like we were planned.

Some Christians might find Simon Conway Morris' viewpoint, with its implicit teleology, more attractive. Others, perhaps motivated by a high view of providence, may find Gould's emphasis on contingency equally congenial to their faith. What do you think?

Video transcript

I think there are sometimes a couple of biblical images we struggle to lay hold of. In the New Testament we find when we talk about life, we have the idea of living or ‘bios’. In other words, we talk about how we are alive. But Jesus talks about the fact of “coming to life “ when we know him. That doesn’t suddenly mean that our heart starts beating. It means that there is this whole side to us which was dead… which wasn’t alive and is now… that has actually sprung to life. And we run into complications maybe if we reduce all of these things into exactly the same categories. Now you can have the same issues with ‘death’ too. That word is used in many ways, and different words are used to try and signify various different things.

Now what is interesting is that if you go back into the Genesis account, it says “now do not eat this [apple] or you will surely die”. There is a whole chain of events that happens when Adam and Eve decide they want to walk away from God. The first thing that happens is that they cover themselves up. There’s like a psychological alienation that comes. They are no longer happy with the way they are. The next thing that happens is God steps into the garden, they run and hide. There is spiritual alienation. The voice that was once welcoming where they went, they now find themselves cut off from that. Then there is a social alienation that comes as a result of turning away from God. They start blaming each other. There is a vocational alienation that comes as a result of, of course, judgment. That which was meant to be home for them, all work become labor, and we could keep going.

So when we talk about “death” the picture, to me, seems to be much bigger, much fuller. I can’t think of a more comprehensive view of possibly what it could mean. And so I think we need to again break away from a straight forward, in fact, mechanistic understanding. In no way do I think that impoverishes either or understanding of the gospel or of the cross. As a matter of fact, it enhances it. It makes the work of the cross even more incredible and it makes the idea that God is looking for redemption from us more complete. We are not talking simply about the idea of physically living forever because that’s clearly not what it means. We know that we are going to physically die. All of us. But when you think about it in terms of what that means psychologically, spiritually, emotionally, socially, vocationally and so on it becomes a huge picture. The text is teaching us something which is real, which is true, which is there. I think we just need a bigger more sophisticated handling of the text, than a reductionist one that I think actually impoverishes or understanding of The Fall, the cross, redemption, the ‘coming again’ and so on.

"Reply the tape a million times ... and I doubt that anything like Homo sapiens would ever evolve again" (Stephen Jay Gould from "Wonderful Life", 1989 p. 289, Harvard University Press.).

With his standard panache, the late Harvard paleontologist Stephen J. Gould argued strenuously that evolution had no inherent directionality. It was a cosmic crapshoot - in no way destined to produce anything complex, self-conscious or human. We are mere accidents; a "tiny twig on an improbable branch of a contingent limb on a fortunate tree" ("Wonderful Life" p. 291). Highly fortunate indeed! Eons ago, a dinosaur-dominated earth held little promise for mammalian ascendancy (let alone primates or humans). Our distant ancestors might have remained little more than scurrying nuisances nipping at the feet of giants if not for a most unlikely calamity - a massive meteor strike which swept away the dinos and forever altered the earth's bio-saga. Who would have guessed?

Evolution's capricious nature seemed to represent a severe stumbling block for the Abrahamaic religious traditions. In their narrative, humans represented the culmination of God's creative work - the very purpose for creation itself. But evolution is an awfully shoddy way of enacting a divine plan. Gould delighted in annoying the faithful by emphasizing this very point:

"Odd arrangements and funny solutions are the proof of evolution - paths that a sensible God would never tread but that a natural process, constrained by history, follows perforce" ("The Panda's Thumb", 1980, pp. 20-1).

Theologians, however, were quick to point out that the chance element in evolution was neither new nor necessarily contrary to the Judeo-Christian view of God. Human history was replete with chance; evolution only extended the theme. Moreover, chance allowed for freedom - a virtue high on God's agenda. However theologically sound these retorts may have been, their force was often lost on the average believer. The accidental nature of human existence provided just another reason to reject evolution altogether in order to preserve God's special concern for humanity.

Gould was a talented science writer, but he overplayed evolution's whimsy. Increasingly, science is showing that the evolutionary process has many built in constraints which limit its possibilities and bias its pathways. Take, for example, the ubiquitous phenomenon of convergence - the tendency for highly diverse species to independently evolve similar adaptive (analogous, not homologous) traits. Most of us are familiar with the saber-toothed tiger, the scourge of our hominin ancestors. Less familiar are a group of South American marsupials called the thylacosmilids who independently evolved similar protruding saber-teeth. Convergence can also be seen in a number of specifically human traits. For example, we share a mode of locomotion, bipedalism, with birds, kangaroos, and some dinos. The lateralized and convoluted structure of our brains can also be found in octopi, this despite the fact that vertebrates and cephalopods diverged from one another over 450 million years ago.

In his book "Life's Solution" (2003, Cambridge Press) Cambridge Palaeobiologist Simon Conway Morris documents scores of examples of convergent evolution from insect body designs to the social systems of dolphins and chimpanzees (both fission-fusion). The important lesson is that there are only a limited number of ways that evolution can solve the adaptive problems posed by the earth's ecosystems. Time and again, evolution stumbles upon the same general design features from which to fashion adaptive traits.

Now add to this the Baldwin effect - an idea originally proposed in 1896 wherein organisms are posited to actively shape their own selective forces. For example, suppose some fairly intelligent primates begin fashioning tools, giving them access to new resources and a competitive advantage over non-tool users. Any genetic predisposition facilitating tool use would also be positively selected.

A severe limitation on Baldwin effects has always been the unpredictability of genetic mutation. For any heritable genetic changes to occur (so the thinking has always been) our tool wielding primate would just have to wait around and hope for a lucky "tool use" mutation to pop up. But maybe not. Two recent books, Jablonka and Lamb's "Evolution in Four Dimensions" (2005 MIT press) and Kirschner and Gerhart's "The Plausibility of Life" (2005, Yale University Press) discuss connections between recent work in genetics and Baldwinian processes. What if the primate's tool use actually raised the probability that a tool-relevant genetic change would take place which could then be passed along to offspring?

Recent genetic research (in a field called epigenetics) shows that experiences occurring over one's lifetime can produce heritable genetic changes. For example, mice exposed to two weeks of environmental enrichment (more social interaction, activity, novel objects to explore) show evidence of enhanced memory function (not surprising). More surprising is that their offspring also show evidence of enhanced memory even though they were never exposed to environmental enrichment (Journal of Neuroscience, 29, p. 1496). Thus, the increased environmental stimulation created a genetic change in the parents that was then transmitted to offspring. This change appears to involved altered patterns of gene regulation (how genes are turned on and off during development). Similar effects have been noted in humans (see European Journal of Human Genetics, 14, p. 159).

Convergence, epigenetic inheritance, and Baldwin effects are only a few of the mechanisms serving as directional constraints on evolution's pathways. In his review of the various factors affecting the evolutionary process, anthropologist Melvin Konner concludes:

"There are no intrinsic driving factors in evolution, but there are intrinsic constraints and canalized paths along which either evolution or development may more easily proceed" ("The Evolution of Childhood," Harvard Press, 2010, p. 59, emphasis in original).

Of course, none of these constraining factors guarantee our arrival on the evolutionary stage. They do, however, raise the odds that in time a complex, rational, self-aware creature capable of entertaining both scientific and religious ideas might emerge.

The more we understand evolution, the less it seems like neither the bogeyman that creationists fear nor the universal God-dissolving acid some atheists crave.

While these are indeed complex questions, some of the problems do stem from misunderstandings about what randomness means in a scientific sense and what role it plays in evolution. To help clarify some of these details, we offer these resources.

The “Randomness” installment of our Distinctions series (first posted earlier this year) looks at some of the basic misconceptions about the role of randomness in evolution. While it is understood by many simply to mean blind, undirected and purposeless, in truth, randomness is far more complex and awe-inspiring than this overly-simplified definition. Whether through genetic mutations or the combinations that occur between sperm and eggs, these processes can be seen as the continual unfolding of something that is decidedly not random--creation itself. Randomness, in essence, generates certainty. This is further illustrated in the second video.

In the clip “Randomness” from the upcoming film A Leap of Truth by Ryan Pettey, Richard Colling, Ard Louis, and John Polkinghorne offer several examples of random processes leading to order rather than disorder. As Dr. Louis points out, the scientific definition of “randomness” is quite different from our everyday understanding of the word. In fact, random generation is the most efficient way to generate complexity. Polkinghorne further notes that we live in a world where the balance of random mutations is almost perfectly tuned for fruitful life on Earth. This, we learn, is God's process: Randomness given time, can lead to that which is nearly certain.

This is beautifully illustrated in the following re-post from last year. Here, in a blog called "That's Random," Kathryn Applegate offers two examples of random motion leading to certainty in the process of assembling a virus. Because random processes can lead to that which is almost certain, it is not at all surprising that this has frequently been used by God over billions of years to create order out of chaos--God's creation, by God's way, in God's time.

That's Random

You hear it all the time: “That’s so random!” When used by people of my generation, the word “random” can simply mean “cool” or “surprising.” Or it can mean something like “disconnected,” as in the phrase, “I had a random thought” (which returns 189,000 hits on Google, by the way—random!).

Despite this usage, most of us know that randomness has something to do with probability, and that it often implies a lack of conscious intentionality. But what do mathematicians and scientists mean when they say something is random? Can a random process lead to an ordered, even predictable outcome? Is there evidence that God makes use of random processes to fulfill his creative purposes?

These are big questions, and we won’t address them all today. But I think randomness is an important topic to cover for two reasons: 1) it is integral to many processes in biology (and math, physics, chemistry, etc.), and 2) it is commonly misunderstood to be incompatible with Christianity.

As I said above, most of us know that randomness has something to do with probability. If you pick a card “at random” from a shuffled deck, you have a small probability of drawing an ace (4 out of 52, or a 7.7% chance). If you flip a coin, you have an equal probability of getting heads or tails.

Randomness also seems to imply a lack of intentionality or purposefulness. After all, you might hope for an ace when you draw a card, but you can’t choose one on purpose. You might call heads when you flip a coin, but you can’t know beforehand what the outcome will be. Thus the outcome is indeterminate, but is it purposeless? Not necessarily. Indeterminacy simply means the result cannot be predicted from the outset.

It should be noted that indeterminacy does not imply that God does not have foreknowledge of future events. Christians ought not to be uncomfortable with the idea of God interacting with his creation through chance. We often describe a seemingly-random (i.e. unplanned by us) sequence of events as being “providential,” or planned by God. A good introduction to the way divine action could drive physical processes can be found in this Question.

In biology, it is very hard or impossible to calculate precise probabilities for most processes, so when we say a process is random, we typically mean it is extremely unpredictable. Eventually we will discuss randomness within biological evolution, but first we must consider some simpler processes, like the self-assembly of a virus.

Viruses are remarkably efficient entities. Coiled tightly within a protein-based shell is a small amount of DNA needed for self-replication. The shell, called a capsid, is made of many repeating protein subunits and is therefore highly symmetrical (see figure). Important biomedical insights have certainly been gleaned from structural studies of viruses, but viruses also teach us about the emergence of order from non-order.

The virus life cycle has four main steps: 1) enter a host cell, 2) hijack the cell’s replication and translation machinery to make many copies of itself, 3) assemble into many virus particles, and 4) exit the cell to invade another host.

When I first learned about this process, I found it very hard to believe it just “happens.” The idea that a bunch of molecules bumping into each other inside a crowded cell could spontaneously assembly into a fully-functional virus seemed a bit far-fetched. Many viral capsids have over 100 protein subunits that must interact with each other in just the right way, or it won’t work. Surely there must be something driving this process, right?

There is! Random motion. I had to see it to believe it. I distinctly remember sitting in class during my first year of graduate school when the professor demonstrated self-assembly of a virus using a 3D model as shown in the following video. In less than 30 seconds, you can watch a jumbled heap of proteins become a beautifully ordered structure.

As the narrator explains, sub-assemblies form and break apart en route to the most stable structure, the full capsid. As the sub-assemblies begin to form, further associations with free subunits become more favorable and as a result occur rapidly, while the final steps may take considerably longer. While the subunits in the model are rigid, in reality the proteins take on multiple conformations, allowing the capsid to “breathe.”

Amazing as it is, the system we just considered—one virus capsid in a jar—is pretty simple. One wonders how self-assembly can happen in a crowded cell, where there are countless other molecules diffusing around, potentially getting in the way. We can’t directly see how it happens in a cell, but we can reconstitute the process in a test tube using different combinations of constituent molecules.

Consider two viruses, where each protein subunit in one virus is the mirror image of the corresponding subunit in the other. Putting the two viruses together by hand would be pretty tricky, because the constituent parts look so similar. But random motion can do the job in short order:

From this model, we can see clearly, in real-time, how distinct complex structures can arise from their parts randomly interacting with one another. Many large viruses also use special scaffolding proteins to assist in the assembly process, and some even use their own genomes as a scaffold. In addition, two closely-related viruses that happen to infect the same cell can exchange parts to create a new virus. This is one way viruses can evolve quickly to evade the host’s immune system.

Here we have seen how viruses demonstrate a principle inherent in God’s world—that order can emerge out of chaos from random processes.

1. From Scot: Could you explain the difference between creationism, intelligent design, and "evolutionary creationism"?

“Creationism” is one of those words that almost always needs clarification. For many, “creationism” is synonymous with Young-Earth Creationism, the view that the Genesis narratives are to be taken literally. This view holds that the entire cosmos is around 6,000 years old, that the fossil record was laid down almost in its entirety during a literal, global worldwide flood, that God created humans directly out of dust, and that Adam and Eve are the progenitors of the entire human race. The organization Answers in Genesis is probably the best-known proponent of this view.

Old-Earth Creationism typically holds to a local flood, and accepts Big Bang cosmology. Despite agreeing with mainstream science on these issues, they deny evolution: they believe that the vast majority of species (and especially humans) were independently created by God during earth’s long history. Old-earthers also hold to a literal Adam and Eve as the progenitors of our entire species. Reasons to Believe is the best-known organization that promotes this view. You can read one of my (somewhat technical) critiques of their anti-evolutionary genetics arguments here.

Intelligent Design (ID) is a view that many feel is a form of creationism, though the ID Movement itself often rejects the label, claiming that it is strictly an alternative scientific view. The ID Movement is a “Big Tent” approach for all and sundry who reject at least some part of evolutionary biology. As such, there are Young-Earth Creationists, Old-Earth Creationists, and others within the movement. The main ID view is that some features of life are too complex to be the result of evolution, thus indicating that they were “designed” – a word that functions as the equivalent of “created” within this group. The Discovery Institute is the best-known organization for promoting ID. I’ve spent a lot of time critiquing the ID movement, and you can find much of that material on the BioLogos web site (do an author search there using my name).

Despite their (large) differences, all of the above positions deny some aspect of modern science. The only Christian perspective on origins that fully accepts mainstream science is the Evolutionary Creation / Theistic Evolution view. This view holds that science is not an enemy to be fought, but rather a means of understanding some of the mechanisms God has used to bring about biodiversity on earth. This view accepts that humans share ancestry with all other forms of life, and that our species arose as a population, not through a single primal pair. There are different views within the EC community on whether there was a historical couple named Adam and Eve – some hold that there was, and that they were selected by God from a larger population as representatives. Other folks in the EC community feel that Adam and Eve are typological figures, such as a representation of the failure of Israel to keep the covenant. The science (human population genetics) is clear that our species arose as a population, and that is what I have focused on (since that is my area of expertise). I try to leave the theology to others, but often folks want to talk theology on these points, not science.

2. From Paige: What has been the most compelling evidence for you personally that has solidified your position as an evolutionary creationist?

Well, the evidence is everywhere. It’s not just that a piece here and there fits evolution: it’s the fact that virtually none of the evidence we have suggests anything else. What you see presented as “problems for evolution” by Christian anti-evolutionary groups are typically issues that are taken out of context or (intentionally or not) misrepresented to their non-specialist audiences. For me personally (as a geneticist) comparative genomics (comparing DNA sequences between different species) has really sealed the deal on evolution. Even if Darwin had never lived and no one else had come up with the idea of common ancestry, modern genomics would have forced us to that conclusion even if there was no other evidence available (which of course manifestly isn’t the case).

For example, we see the genes for air-based olfaction (smelling) in whales that no longer even have olfactory organs. Humans have the remains of a gene devoted to egg yolk production in our DNA in exactly the place that evolution would predict. Our genome is nearly identical to the chimpanzee genome, a little less identical to the gorilla genome, a little less identical to the orangutan genome, and so on – and this correspondence is present in ways that are not needed for function (such as the location of shared genetic defects, the order of genes on chromosomes, and on and on). If you’re interested in this research, you might find this (again, somewhat technical) lecture I gave a few years ago helpful. You can also see a less technical, but longer version here where I do my best to explain these lines of evidence to members of my church. For those wanting even more info, a few years ago I recorded a series of lectures given to my non-majors, intro biology class that explored evolution and Christian responses to it in depth.

3. From Rob: I have trouble with randomness in natural selection. Why is it essential in scientific terms that evolutionary development is random? How does that fit with the notion of a God who is involved in the world? …Random evolution would not be theism (or it wouldn't Biblical Christianity). It would be deism; the Great Clockmaker who set everything in motion and then kept hands off. Why is randomness essential scientifically, and how does a Christian accept it theologically?

I think you mean randomness in mutation: natural selection is anything but random (it’s a process whereby certain variants in a population reproduce more successfully than others). Evolution has a random component (mutations arise that may be detrimental, neutral or beneficial) and an emphatically non-random component (the different variants within a population do not all reproduce at the same frequency, meaning that the next generation will not be exactly like the previous one). So, as a whole, evolution is not random since it has a strongly non-random component. Evolution is actually remarkably good at producing similar results over and over again: consider how similar ichthyosaurs (descended from terrestrial reptiles) and dolphins (descended from terrestrial mammals) are. That’s the non-randomness of evolution at work. Some evolutionary creationists have argued that this non-randomness of evolution is a way that God uses evolution to shape His creation (the best work on this topic is Life's Solution by noted Cambrian paleontologist Simon Conway Morris).

4. From HMV: I agree with you that the evidence seems to point to evolution being true. I've read Biologos and the old Evolution and Evangelicals blog. I've read books where people try to rework theology in light of this scientific knowledge. And yet, I'm left feeling confused and unsatisfied about doctrines like sin, the Fall, salvation, etc. What about you--have you found a satisfying way to maintain your evangelical theology in light of evolution?

This is a tricky question, because it hinges on the inherently subjective term “satisfying.” What I might find satisfying you might not – and in order to answer the question I have to guess at what you mean by it.

Personally, the concept of Divine accommodation has been helpful to me. This is a theology that has a long heritage in Protestant circles (e.g. Calvin). In a nutshell, it’s the idea that God, in his grace, brings himself down to the level of the audience he is communicating with. For Genesis, that audience is an ancient near-eastern culture, not our modern scientific one. For Genesis, my view is that God wants to communicate that he is the Creator of all that there is, that he has given humanity a special image-bearing role within it, but our sinfulness has broken that relationship, et cetera – but that he doesn’t see a need to give them a science lesson first. I would recommend Denis Lamoureux’s book I Love Jesus & I Accept Evolution and, though not directly related to science, Peter Enns’ book Inspiration and Incarnation may also be helpful to you (it certainly was to me).

5. From Chris: From the perspective of an evolutionary creationist, what meaning and value do you extract from the creation accounts in Genesis and why would they be important for the Christian faith if they can't be taken literally?

See the answer above – I see the Genesis narratives as God graciously reaching down to an ancient culture in order to communicate to them that he is their creator, that they are alienated from him, and that he desires that they be restored to fellowship through his offer of covenant with him (ultimately pointing to the need for God to step into history himself as the One who can keep the covenant on our behalf).

6. From Paige: I'll never forget sitting in one of Dr. Charlie Liebert’s classes several years ago and hearing him ask the question: "What came first, death or sin?" If we believe that there was no death before sin, it causes a wrinkle in our ability to hold to the theory of evolution. As a scientist, this question caused him to reexamine the evidence. How have you personally dealt with this "wrinkle?"

Yes, if you believe that no death of any kind (plant, animal, bacterial) occurred before human sinfulness, then this precludes an evolutionary view, since the fossil record is (obviously) a record of things, well, dying. If you hold that no human death came before sinfulness, then it depends on what you call human (there is a gradation of forms leading up to the modern human skeleton in the fossil record, as well as the overwhelming genetic evidence that we arose through an evolutionary process) and what you consider sin (i.e. when did we become accountable to God for our actions?). There is also the long-standing observation that God decrees that Adam and Eve will surely die the day they eat of the fruit – and then they live for several hundred years after the fact. I’d also recommend reading through Romans 5:12 – 8:17 (which, as you know, is all about Adam, sin and Christ as the second Adam) and making a mental checklist of how Paul uses the term death in this passage. References to physical human death are in the minority – suggesting that Paul’s understanding of what is going on in Genesis has a lot more nuance than a simple literal reading would imply.

7. From Jane (from her husband, an atheist): All of the questions posted so far approach the topic from the viewpoint of assuming belief in a god. As an atheist, I don’t share that assumption. (For those who might not appreciate it, evolution offers a mechanism for understanding the existence of living organisms that doesn’t require the existence of a god.) If you transitioned from an anti-evolutionary/pro-intelligent design view to an evolutionary creationist view a few years ago,” why didn’t you keep going and just embrace evolution and drop the theistic aspect?

Your question implies that there is a natural trajectory from accepting evolution to rejecting God. As a theist, specifically an evangelical Christian, I don’t agree with this point, though I understand where you are coming from. Let me explain.

Your assumption, that “evolution offers a mechanism for understanding the existence of living organisms that doesn’t require the existence of a god” holds weight only if one has the view that “natural explanations” and “theistic explanations” are a zero-sum game. This is a God-of-the-gaps approach, where God has less and less to do as we understand more and more how nature works (and a view I reject). Logically, if I held this view I would view science as an inherently evil activity, since any natural explanation diminishes the activity of God from this viewpoint. Your view is also one that science cannot establish as correct, since science cannot speak to the absence of divine action in an observed phenomenon.

If, on the other hand, one believes that “natural explanations” reveal the means by which God ordains and sustains his creation, then “natural explanations” are not a threat to theism at all, but rather a window into the ways God acts in the world. This is the view I hold, and it too is a view that science cannot establish. Both theistic evolution and atheistic evolution are philosophical / theological interpretations of what science can establish: evolution.

As for “drop(ping) the theistic aspect” – this would imply that my faith was based on a particular understanding of creation such that I would question my faith when I questioned the mechanism of creation and/or my interpretation of Genesis. This wasn’t really an issue for me, since my faith was, and is, based on believing that Jesus of Nazareth is in fact the resurrected Lord of the entire world (to roughly paraphrase how N.T. Wright puts it) and that the resurrection is God the Father’s vindication of Jesus’ messiahship (as a sinless, suffering servant that, mystery of mysteries, turns out to be God Himself, incarnate). None of that belief was ever predicated on a specific interpretation of Genesis with respect to scientific details, and as such, accepting evolution as a mechanism by which God creates did not alter those beliefs. (If you’d like to see a rational, historically-rooted investigation of the credibility of the resurrection, N.T. Wright’s The Resurrection of the Son of God is the standard by which others are judged.)
