Wilkinson identifies a number of themes found throughout the Bible that can help us understand the Creator God in a more complex and fulfilling way—as, in Wilkinson’s own words, “a Creator God who is worthy of worship, enjoyment, and trust.”

Understanding John Polkinghorne: Theology of Nature

John Polkinghorne’s interest in natural theology is important, but what really sets him apart from most others is that he combines it with an equally strong interest in theology of nature, which is not the same thing. Where natural theology involves, “metaquestions about the pattern and structure of the physical world,” theology of nature involves, “metaquestions about how its historical process is to be understood.” Rather than “looking to the physical world for hints of God’s existence,” we look “to God’s existence as an aid for understanding why things have developed in the physical world in the manner that they have.” (Belief in God in an Age of Science, p. 13)

On this front, Polkinghorne advances a strongly Christocentric theology of creation, stressing Jürgen Moltmann’s notion of The Crucified God . In the context of Polkinghorne’s theology of nature, the point is that the Creator is the crucified and resurrected second person of the Trinity. Since I devoted a column to this before, I won’t say more here, except to alert readers to the singular importance this particular idea has for him—especially when facing the problem of suffering. “The insight of the Crucified God lies at the very heart of my own Christian belief, indeed of the possibility of such belief in the face of the way the world is.” (Belief in God in an Age of Science, p. 44)

Situating John Polkinghorne: The Resurrection of Jesus

Many Christians today see science as posing dangerous threats to their faith, challenging their understanding of the Bible and undermining core tenets such as the bodily Resurrection of Jesus, the historical basis on which the Christian faith stands or falls. “Evolution” is often identified as the problem, but the real danger is unbridled naturalism. A commitment to naturalistic methods, known as “methodological naturalism,” (MN) has been an integral part of science and medicine since the ancient Greeks. Those methods have been highly successful at producing a coherent, often very convincing picture of nature and the history of nature.

Advocates of Intelligent Design and some other Christians reject MN, but many Christians who work in the sciences and related fields (such as engineering, medicine, or the history and philosophy science) support MN as a properly grounded and properly limited way of understanding reality. In their view, a robust Christian faith is consistent with a commitment to MN, provided that the limits of scientific inquiry are not simply equated with the limits of rationally grounded belief. Polkinghorne fits squarely in this category.

To understand more clearly where Polkinghorne lies on the larger landscape of science and religion, let’s consider his approach to the Resurrection. Many contemporary thinkers, including some theologians and clergy, believe that “science” has somehow made it impossible to believe in the Resurrection, the deity of Jesus, and even belief in the transcendent God of the Bible.

A prime example is John Shelby Spong, a retired Episcopalian bishop whose books have sold more than one million copies. Spong sees the bodily Resurrection as a figment of the disciples’ imaginations, a vestige of a theism that now we must throw away like a threadbare suit of clothes. For Spong, Christians today need to go "beyond theism" throwing out the baby of divine transcendence—the fundamental truth of monotheism—along with the bath water of the credulity and mythology of the pre-modern authors of the Bible and the ecumenical creeds. Spong’s message is that “Christianity must change or die,” and all in the name of “science.”

As Spong likes to say, his work is very controversial, and not just among rank-and-file Christians. Scholars have also railed against him. “I have been attacked in books from the religious right by such people as Alistair MacGrath [whose surname is actually spelled McGrath], N.T. Wright, and Luke Timothy Johnson,” he complains (Why Christianity Must Change or Die, p. xvi).

I understand (with much sadness) that we live in a highly polarized age. Nevertheless, it’s difficult for me to grant much credibility to an author who identifies McGrath, Wright, and Johnson as representatives of the “religious right.” Indeed, if anyone here is distorting the news it is Spong, not they. As the (late) great Catholic biblical scholar Raymond Brown once observed, “I do not think that a single NT [New Testament] author would recognize Spong’s Jesus as the figure being proclaimed or written about.” (Birth of the Messiah, note 321 on p. 704)

Matthias Grünewald, The Resurrection (a wing of the
Isenheim Altarpiece, ca. 1515), Unterlinden Museum,
Colmar, France

Polkinghorne certainly understands science far more than Spong does, and his conclusions about the implications of science for Christian beliefs are markedly different. With respect to the Resurrection, he is basically on the same page with his friend Wright, whose profound book, The Resurrection of the Son of God, he cites with appreciation. Belief in the Resurrection is well supported by the evidence, and the Resurrection, itself, is “the pivot on which the claim of a unique and transcendent significance for Jesus must turn.” Considering authors like Spong (although he does not explicitly name him), he adds, “it would be a serious apologetic mistake if Christian theology thought that operating in the context of science should somehow discourage it from laying proper emphasis on the essential centrality of Christ’s Resurrection, however counterintuitive that belief may seem in the light of mundane expectation.” (Theology in the Context of Science, pp. 135-6)

Amen.

Looking Ahead

This is the Easter season, and I’ll return in a couple of weeks to begin examining Polkinghorne’s approach to the Resurrection more fully, using excerpts from the chapter on “Motivated Belief” from his recent book, Theology in the Context of Science.

To illustrate why the debate about origins isn’t simply a matter of science versus religion, imagine living in a culture where there is a similar debate about the weather. The Bible clearly teaches that God governs the weather. Many Bible passages proclaim that God causes rain and drought (see Deut. 11:14-17; 1 Kings 8:35-36; Job 5:10; 37:6; Jer. 14:22). Writers of Deuteronomy, the Psalms, and Jeremiah refer specifically to storehouses of rain and snow (see Deut. 28:12, 24; Ps. 135:7; Jer. 10:13).

What causes the rain? Most of us were taught that water evaporates from the ground level, rises to where the air is cooler, and condenses into water droplets that form clouds. We learned how cold fronts and warm fronts and low pressure systems bring rain. When we watch meteorologists on television, we hear that scientists now use sophisticated computer models to help them understand and predict the weather a few days in advance. Their ability to understand meteorology is especially important for farmers, airline pilots, military personnel, and coastal residents. Every year scientists develop increasingly accurate computer models of the weather.

Now imagine that debates arise about what should be taught in schools about the weather. Imagine that prominent scientists write popular books about meteorology that state, “From our scientific understanding of the causes of wind and rain, it is clear that no divine being controls the weather.” Imagine that a professional organization of science teachers writes a set of guidelines that state, “Students must learn that all weather phenomena follow from natural causes; weather is unguided and no divine action is involved.” Meanwhile, other people insist that these scientific explanations of rain and wind must be wrong because the Bible clearly teaches that God governs the weather. These people write books and give public speeches saying, “Atheists have invented their godless theories about evaporation and condensation. But we can prove that their so-called scientific theories are false and that the Bible is true.” They go to churches and teach, “If you believe what these scientists are saying about the causes of wind and rain, then you’ve abandoned belief in the Bible.” They petition school boards and courts to require that science classrooms also teach their “storehouses” theory of the weather as an alternate explanation to evaporation and condensation.

If you lived in a world with that sort of debate going on, would you be content to see it simply as a conflict between science and religion? Would you be willing to agree wholly with one side or the other?

Fortunately, we don’t have such debates about what causes the weather. The majority of Christians say that when it comes to the weather, both science and the Bible are correct. God governs the weather, usually through the scientifically understandable processes of evaporation and condensation. And the majority of atheists today would also agree that having a scientific explanation for the weather, by itself, neither proves nor disproves the existence of God. So there are no court battles about what science classrooms should teach about the weather. Debates about creation, evolution, and design have some similarities to the above example, but in many ways they are more difficult. The questions about how to interpret Scripture are more challenging, and these debates raise more theological issues. Still, a good place to start in making sense of these debates is to remember that more than two options exist; it is not simply a choice of science or faith.

Christians in Agreement

When Christians discuss creation, evolution, and design, it is easy to focus immediately on areas of controversy and disagreement. We think it is important to start by pointing out certain areas on which nearly all Christians agree. Christians generally agree about the fundamentals of God, God’s Word, and God’s world in the five areas.

God created, sustains, and governs this universe.

This truth is confirmed in the first line of the Apostles’ Creed, one of the ecumenical creeds of the church which many Christians recite every week: “I believe in God, the Father almighty, creator of heaven and earth.” Christians believe that God created all things from nothing, bringing them into being through his Word, his Son (John 1:1-3). God continually sustains the whole universe, governing all creatures according to his providential care.

The God who created this world also reveals himself to humanity.

God has revealed himself at various times and in multiple ways throughout history, including the written Scriptures and the Incarnation. As it says in the first verses of the book of Hebrews,

In the past God spoke to our ancestors through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son, whom he appointed heir of all things, and through whom also he made the universe. The Son is the radiance of God’s glory and the exact representation of his being, sustaining all things by his powerful word. After he had provided purification for sins, he sat down at the right hand of the Majesty in heaven. (Hebrews 1:1-3, NIV)

The God who created this world is also our Redeemer.

We belong to God because he created us, but when humanity turned from God he bought us back. He redeemed us through the incarnation, life, suffering, death, and resurrection of Jesus Christ.

The Bible is authoritative and sufficient for salvation.

God inspired its human authors and ensured that the Bible truthfully teaches what he intends. The Holy Spirit testifies in our hearts that the Bible’s message is from God, not merely human writing. Christians accept the sufficiency of the Bible for establishing our core beliefs and practices; all that we need to know for salvation is taught there. God certainly can use various means— including the natural world—to teach us new things. But these new things should be compatible with, not contradictory to, what God teaches in Scripture.

God is sovereign over all realms of human endeavor and has given human beings special abilities and responsibilities. Theologian Cornelius Plantinga puts it this way:

God’s creation extends beyond the biophysical sphere to include the vast array of cultural possibilities that God folded into human nature. . . . God’s good creation includes not only earth and its creatures, but also an array of cultural gifts, such as marriage, family, art, language, commerce, and (even in an ideal world) government. The fall into sin has corrupted these gifts but hasn’t unlicensed them. The same goes for the cultural initiatives we discover in Genesis 4, that is, urban development, tent-making, musicianship, and metal-working. All of these unfold the built-in potential of God’s creation. All reflect the ingenuity of God’s human creatures—itself a superb example of likeness to God. —Cornelius Plantinga, Engaging God’s World, 2002.

Applying this idea to the natural sciences, we conclude that God has graciously given humans the ability and responsibility to study the natural world systematically. As with all human endeavors, we do it imperfectly. We must seek to do it as God’s imagebearers, in gratitude for God’s gifts.

Christians in Disagreement

Christians have always agreed about who created everything, but in the last few decades they have often disagreed about how God created everything. These disagreements are over two basic questions:

• As we study God’s Word, what is the best way to understand passages that talk about God’s acts of creation?
• As we study God’s world, what can we reliably conclude that it tells us about its history?

Some Christians describe themselves as young-earth creationists. They believe that the best interpretation of the book of Genesis is that the earth is only a few thousand years old and was shaped by a global flood. Young-earth creationists hold a range of views about how to interpret Scripture, the extent to which scientific data indicates a young universe, and the extent to which it indicates at least an appearance of long history.

Other Christians describe themselves as old-earth creationists. Some believe that in the best interpretation of Genesis 1, the events on each day actually describe several long epochs of scientific history. Others believe that the best interpretation of the book of Genesis does not imply anything about the age of the earth one way or the other and that drawing conclusions about the age of the earth from Scripture is reading into it something it was never intended to teach.

Some old-earth creationists describe themselves as evolutionary creationists. They believe that the best understanding of the scientific data—in conjunction with the best interpretation of Scripture—implies that God governed and used evolutionary processes in the unfolding of creation. Other old-earth creationists describe themselves as progressive creationists. They believe that science and Scripture both indicate that God used not only natural processes but also some miracles along the way, particularly in the history of life. Arguments for Intelligent Design are usually, though not always, used to support versions of progressive creation.

In the remainder of the book Origins, the Haarsmas expand on these topics, investigating different Christian positions in detail.  Stay tuned for more excerpts in future posts.  Next week, we’ll feature an excerpt on the reliability of historical science.

“This is 2,300 year old wisdom from the Book of Ecclesiastes that seems to very concisely understand the water cycle. That water evaporates from the ocean, gets stored in the atmosphere via clouds, comes down as snow or rain, and when it comes down on the mountain it’s often stored there, as snow is gathered via groundwater, streams, and rivers, and then through the river, returns to the ocean, again. What a beautiful, complex, interdependent, wonderfully mysterious way of providing water, life to the land … But what does this beautiful system teach us, Father, Son and Holy Spirit, about who we are? What is your word, God, about this river, that runs through the center of where we live?”

In this sermon, Pastor Jon Van Sloten of New Hope Church in Calgary, Alberta, describes how he set out to learn where the water from the Bow River, near their home in the Rocky Mountains, actually comes from. He interviewed scientists who study hydrology and have learned a curious truth about how this particular river keeps a steady flow the full year round. This modulating geophysical “safeguard,” which allows the Rocky Mountains to hold water and let it out at a slow trickle rather than a deluge during the annual snowmelt, speaks to Van Sloten of God’s grace at work in the world—grace we can’t see with the naked eye, but is there all the same.

What does it mean for humanity to be created “from the dust of the ground?”

In many ancient Mesopotamian creation stories, human beings were depicted as deriving from some physical part of the gods. Often this was the result of conflict: humans arose from the blood, flesh or tears of gods slain by other gods. Humans created in this fashion were supposed to serve the gods by performing menial work that the gods had tired of doing themselves. The lot of humanity, then, was one of violence and servitude.

In the Israelite creation stories reflected in Genesis 1 and 2, however, humans are made from the ordinary material of creation: “dust.” Humans are made of earth-stuff, not god-stuff.

At first glance, it may seem that this lowers the status of the human creature. We might ask the question raised by Eliphaz in the book of Job:

Can a mortal be more righteous than God?
Can even a strong man be more pure than his Maker?
If God places no trust in his servants,
if he charges his angels with error,
how much more those who live in houses of clay,
whose foundations are in the dust, who are crushed more readily than a moth! (Job 4:17-19)

Indeed, our humble origins ought to remind us of the fragility of our lives. As the Psalmist says,

You turn people back to dust, saying, “Return to dust, you mortals.”
A thousand years in your sight
are like a day that has just gone by,
or like a watch in the night.
Yet you sweep people away in the sleep of death—
they are like the new grass of the morning:
In the morning it springs up new,
but by evening it is dry and withered.

The elements of which our bodies are made are ordinary and abundant. Science tells us that approximately ninety-three per cent of the mass in a living human body is comprised of elements first formed through nuclear fusion in the hearts of stars. Through almost unimaginably vast and ancient cycles of stellar formation and supernova explosions, this “stardust” of elements has been spread throughout the universe. It is as though God scattered the stars across space and time to seed the universe for life, including your life and mine. And we are thereby inseparably connected to each other, to the air we breathe, to the ground we tread, to all the creatures that fill the skies and crawl upon the earth and teem in the seas, to the depths of all the heavens. We are not transcendent of creation. We are creatures.

Yet we are creatures into which God breathed the “breath of life.” We are stardust and more than stardust. We are not reducible to our constituent chemicals. A “man” or a “woman” is not just a gooey sack of water, carbon and trace elements. Hydrogen, oxygen and carbon are not aware of their own existence. These elements cannot reason or pray or love or write poems. Conjunctions of these elements cannot carry any persistent identity across time. They do not exercise will or intentionality or agency. They are not “selves.”

Most of the cells in a human body are in constant flux: aging, dividing, dying, being replaced. The surface layer of human skin is renewed completely about every two weeks. An adult’s skeleton is entirely remade over approximately ten year periods. It may be that only the neurons of the cerebral cortex and a few other types of cells persist throughout the lifetime of a human body. And eventually, it all does return to “dust.”

Yet we think of ourselves as persisting over time, as comprising an “identity,” a “self.” Perhaps the cerebral cortex provides the stable biological platform for identity and selfhood, but something new emerges from the chemical-electrical soup, new patterns of organization, a different level of causation. We can even make choices that reshape ourselves, both physically and psychologically. The very wiring of our brains changes when we make conscious choices. Mind is both shaped by matter and supervenes on matter.

Materialists who wish to collapse all of human identity into brain chemistry overstep the bounds of “science.” A fundamental principle of scientific practice is testability: is it possible to demonstrate empirically whether a proposition is false ? As Saint Augustine observed many centuries ago, the fact that I acknowledge I could be “wrong” about something means that I am a “self” who is capable of making real choices about things that are in fact true or false. “Si fallor, sum” Augustine said – if I can doubt, if I can be wrong, then I must exist. One who is a true materialist “all the way down” cannot test his or her materialism. There is no possibility of “being” right or wrong, indeed no possibility of “being” – there is nothing but chemistry.

Spiritualists who wish to degrade matter in favor of the soul or spirit likewise are not expressing a Christian anthropology. Indeed, one of the first heresies that encountered the early Christian church was Gnosticism. A core belief of Gnosticism was that matter, including the human body, was essentially evil. Salvation for the Gnostics involved the soul’s escape from the prison of embodiment and materiality. The Gnostics treated the body either with disdain – engaging in extreme ascetic practices – or with antinomian abandon – engaging in extreme sexual license. Either way, their practices were rooted in the belief that matter and the body were unimportant. It’s easy to see how this view continually creeps into both our popular culture and our Church cultures.

Christian theology asserts that humans are spiritual creatures, a unity of body and spirit or “soul,” integrated, not reducible downwards to mere matter or upwards to mere spirit. Perhaps there is no better way to bring these themes together than with a Psalm — here is Eugene Peterson’s paraphrase of Psalm 139 in The Message:

God, investigate my life; get all the facts firsthand.
I’m an open book to you;
even from a distance, you know what I’m thinking.
You know when I leave and when I get back;
I’m never out of your sight.
You know everything I’m going to say
before I start the first sentence.
I look behind me and you’re there,
then up ahead and you’re there, too—
your reassuring presence, coming and going.
This is too much, too wonderful—
I can’t take it all in!

Is there any place I can go to avoid your Spirit?
to be out of your sight?
If I climb to the sky, you’re there!
If I go underground, you’re there!
If I flew on morning’s wings
to the far western horizon,
You’d find me in a minute—
you’re already there waiting!
Then I said to myself, “Oh, he even sees me in the dark!
At night I’m immersed in the light!”
It’s a fact: darkness isn’t dark to you;
night and day, darkness and light, they’re all the same to you.

Oh yes, you shaped me first inside, then out;
you formed me in my mother’s womb.
I thank you, High God—you’re breathtaking!
Body and soul, I am marvelously made!
I worship in adoration—what a creation!
You know me inside and out,
you know every bone in my body;
You know exactly how I was made, bit by bit,
how I was sculpted from nothing into something.
Like an open book, you watched me grow from conception to birth;
all the stages of my life were spread out before you,
The days of my life all prepared
before I’d even lived one day.

Grantees will benefit from in-person interaction through a series of summer workshops in 2013, 2014, and 2015. These meetings will not only foster a broader knowledge base, but will build a sustained network of scholars and church leaders, both young and seasoned, who are serious about addressing the concerns of the church about evolution. Also in 2015, in connection with the third summer workshop, BioLogos will host a large conference open to scientists, scholars, and church leaders from around the world.

ECF History

In January 2012, BioLogos was awarded a multi-million dollar grant from the John Templeton Foundation to fund the work of scholars and church leaders on evolution and Christian faith. In spring 2012 we worked hard to get the word out. You may have seen announcements on the BioLogos website, in our newsletters, on the Books & Culture, Leadership Journal, or First Things websites, on your professional society’s listserv, or perhaps on your friend’s blog.

The response was overwhelming: we received 225 letters of intent for a total request of $21 million—about seven times the amount we had to offer. We needed to invite the most promising applicants to submit a full proposal, but recognizing the projects with highest potential would require broad expertise. From the beginning, we envisioned that a panel of scientists, pastors, and scholars would oversee the application and review process as well as play key advisory roles throughout the project. A team of eight highly qualified individuals came on board in the early months of the project. They reviewed each proposal and together recommended that BioLogos invite 86 applicants to submit full applications.

The deadline for submissions was October 1, 2012. As in the previous round, the ECF panel evaluated each proposal. In addition, we asked 55 other experts to participate, so that each proposal received 3-4 scores. Criteria for the decision included significance of topic, project design, creativity and innovation, long-term impact potential, feasibility, and budget.

The panel then met together November 29-30, 2012, to make the final funding decisions. In the end, they recommended that BioLogos give 37 awards, ranging from $23,000 to $300,000. BioLogos staff notified applicants of their awards on December 14, 2013.

The Grantees

As part of our objective to create a network of scholars and leaders, we awarded grants to organizations across the U.S. and the world. Thirty of the 37 grantees are domestic; seven are international, hailing from Canada, France, Great Britain, Netherlands, and Spain.

Two-thirds of the accepted projects will be led by teams—some with three or more Project Leaders. We expect that the teamwork and time spent together at our summer workshops will be the start of a long-lasting network of people dedicated to helping the church think carefully about origins.

Applicants chose to apply under one of three program tracks: interdisciplinary scholarship (Track 1), intra-disciplinary scholarship (Track 2), and translational projects (Track 3). Track 1 projects focus on both the collaboration between individuals in different disciplines and the development of projects at the interface of different content areas. Track 2 projects focus on work done within a specific discipline. Track 3 focuses on projects that encourage Christians, especially those within more conservative traditions, to engage in meaningful and productive dialogue to reduce tensions between mainstream science and the Christian faith. The numbers of grantees in Tracks 1, 2, and 3 are 6, 8, and 23, respectively.

Many of the scholarly projects tackle questions about Adam and Eve, the Fall, human identity, and Original Sin—some of the most critical interpretive issues for evangelical theology.  Some examples: 

• Theologian Oliver Crisp of Fuller Seminary will take an analytic theology approach to ask to what extent a theological account of the origin of human sin depends upon the evolution of modern humans from one and only one ancestral pair—especially if that pair does not appear to correspond to what we would think of as modern human beings. 

• Pastor Michael Gulker and philosopher James Smith, leading a large team from The Colossian Forum, ask a related question: if humanity emerged from non-human primates—as genetic, biological, and archaeological evidence seems to suggest—then what are the implications for Christian theology’s traditional account of origins, including both the origin of humanity and the origin of sin? 

• Biologist Dennis Venema of Trinity Western University and New Testament scholar Scot McKnight of Northern Seminary will write a book on the evidence for evolution and population genetics, with informed theological reflection on how these issues interact with orthodox Christianity.

• Biologist David Wilcox of Eastern University will develop an updated model of human identity which reflects the complex recent scientific advances in genetics and paleoanthropology and yet is sensitive to theological concerns.  

These are just a few of the scholarly awards; check out the Grantees page for full descriptions of all Track 1 and Track 2 projects.

All projects have translational potential, but Track 3 projects are designed to meet the needs of a particular constituency within the evangelical church. These projects run the gamut from ethics to education to media production to ministry resources.  Some examples include:

• Theologian Lee Camp of Lipscomb University will produce “The Questions in Monkey Town,” an episode of Tokens, a live variety show that features musical performances, comedic sketches, brief interpretive monologues, and dialog with authors and scholars. The episode will be performed and filmed on the site of the famous Scopes Trial in Dayton, Tennessee.

• Chaplain Joshua Hayashi and Educator Diane Sweeney of the Punahou School in Hawaii will lead a team to produce multimedia curricula aimed at helping high school students connect with their biology curricula and, at the same time, deepen their Christian faith.

• Physics teacher and pastor Benoît Hébert of Science et Foi Chrétienne in France will lead an international, multi-denominational team of French speaking Evangelical scientists, pastors and church leaders to produce a large number of resources on evolutionary creation.

• Pastor Seung-Hwan Kim of Grace Truth Community Church, a Southern Baptist church in Cambridge, Massachusetts, will produce teaching and preaching materials about evolution for church leaders.

• President Gregory Wolfe and Director of Resource Development for IMAGE will gather artists and writers of faith whose work explores the dialogue between evolutionary science and faith practice, convening a conversation between them and scientists, theologians, and church leaders in private and public conferences.

Again, this is just a taste of the diversity of Track 3 projects. Read more about each project on the Grantees page. You can look forward to an incredible variety of resources coming out of the ECF program, many of which will be featured right here on the BioLogos Forum.

Transitional Fossils

Some time ago, the Discovery Institute’s Casey Luskin commented on the human origins exhibit at the Smithsonian Institution, suggesting that palaeoanthropologists use evolutionary theory to describe the progression of the human lineage even when they don’t have transitional fossils with which to work. He writes:

What's ironic, however, is that if you ask the question How Do We Know Humans Evolved? the answer you’re given is, “Fossils like the ones shown in our Human Fossils Gallery provide evidence that modern humans evolved from earlier humans.” So whether you find fossils or you don’t, that’s evidence for evolution.

Indeed, it has become an article of faith for those espousing both the young earth creation (hereafter YEC) model and many who hold to the intelligent design model that transitional fossils do not exist and therefore evolution has not taken place. Support for this position usually entails attacking the weak areas of the fossil record, where burial processes have left us little with which to work, or the creation of straw men arguments in which transitional fossils are defined in such a way that none could ever be found. Often this centers on the concept of “missing link,” a term that is habitually used in the popular press and young earth creation and intelligent design literature when referring to fossil remains but which has little to no meaning for biologists or palaeontologists. As Ahlberg and Clack (Ahlberg and Clack 2006) write:

But the concept has become freighted with unfounded notions of evolutionary ‘progress’ and with a mistaken emphasis on the single intermediate fossil as the key to understanding evolutionary transitions. Much of the importance of transitional fossils actually lies in how they resemble and differ from their nearest neighbours in the phylogenetic tree, and in the picture of change that emerges from this pattern.

Contrary to common misconceptions, the fossil record does not record one single lineage for any family of organisms but rather a series of branches, with many related species coexisting synchronously. Darwin hypothesized that the evolutionary record reflected this bushiness and drew such a diagram in his journal. At the time, though, he had little in the way of fossil evidence to back up this position. Much has changed since his day.

An analogy for understanding this “bushiness” was best described by Prothero and Buell (Prothero and Buell 2007). They suggest that the reader consider his or her own genealogy. You and your siblings are the direct descendents of your parents and, while you are similar to them, each of you has different characteristics not shared with them as well as characteristics that you do share. Your parents have siblings as well (your aunts and uncles), and your grandparents are their last common ancestors. These siblings have their own children (your cousins), who have different and similar traits relative to their parents. They are broadly recognizable as being related to you (“oh, I see you have Aunt Edna’s nose”) but three or four generations out, they will become less and less so. These are the “nearest neighbours” that Ahlberg and Clack describe. In this analogy, each of these cousins represents a transitional form from what was (your grandparents) to what will be down the road.

For example, no one would confuse a frog with a salamander but if you trace the fossil record of each back in time, eventually you encounter a fossil, Gerobatrachus hottoni which was recently discovered (Anderson et al. 2008) that is best described as a “frogamander,” having the basal characteristics of both frogs and salamanders. Had we seen such an animal at the time, it is likely we would not have found it remarkable because it would have resembled the species around it. One lineage eventually diverged into frogs, salamanders and other amphibians. Most (just like Darwin proposed in his tree diagram with the little hatch marks at the tip of many branches) went extinct.

Taxonomy and the Beginnings of Human Origins

All life is classified based on a system devised by Carolus Linneaus in 1735 in his remarkable work Systema Naturae. This system gives all recognized species an individual place based on a system of hierarchy. The study of classification is known as taxonomy. A taxonomic ranking for humans would be this:

When a fossil is excavated, the first thing that the palaeontologist does is make a taxonomic assessment of where it fits in a sequence of known fossils. Traits that are shared with other like species or genera are referred to as primitive traits. Examples of this in humans are five fingers and the presence of three arm bones. We share this with all mammals. Traits that are new or are not shared with other like species are referred to as derived traits. Examples of this in humans are the skeletal changes in the pelvis and the foot to allow for walking upright. We do not share these with any other primates.

Transitional fossils in the human fossil record are distinguished at both the genus and species level. This group includes the extinct genera Ardipithecus and Australopithecus and the current genus Homo. All species except Homo sapiens are extinct. Much of the recent study of early humans focuses on the transition from Ardipithecus (‘Ardi’) to Australopithecus (‘Lucy’ and similar fossils) and from Australopithecus to Homo, the genus that led eventually to us. While each of the australopithecine species identified in the fossil record has derived characteristics that separate them from their ancestors and from each other, only one led to the genus Homo.

In future posts, I will describe the evidence for human evolution and why this evidence is compelling. It suggests that we have had a long, varied history filled with great leaps of change, crushing defeat, and eventual expansion into all areas of the globe.

If a cadre of outspoken, strong atheists wrote a litmus test for scientists, that might very well be question #1.

"Scientists, if you're not an atheist, you're not doing science right," PZ Myers -- a well-known blogger, biology professor and atheist -- regularly preaches.

But if this is true, then as many as half of scientists are doing science wrong. A 2009 study from the Pew Research Center polled members of the American Association for the Advancement of Science (AAAS). Fifty-one percent of respondents reported a belief in a higher power. Does this mean that it's too late for science? Has religion already pillaged the minds of researchers worldwide? No, of course it hasn't.

"It seems to me that we as a society have lately been caught in this false dichotomy where it's either God as the guy with the beard on the cloud or nothing at all," neuroscientist David Eagleman told Discovery News.

Staunch atheists often falsely characterize followers of religion as being "all-in" with their beliefs, opining that they ascribe to the whole creationist, woo-y shebang. "Where's your evidence?" atheists mockingly question. "You can't prove that God exists!" they accuse (correctly). Yet, hypocritically, strict atheists are guilty of the exact same crime: belief without evidence.

"We know too little to commit to a position of strict atheism. [But] we know way too much to commit to any particular religious story," Eagleman said.

Just as it's a leap of faith for a religious person to assert that God incontrovertibly exists, it's an equally large leap for a strict atheist to declare, without question, that God does not exist. As Carl Sagan eloquently explained:

An atheist is someone who is certain that God does not exist, someone who has compelling evidence against the existence of God. I know of no such compelling evidence. Because God can be relegated to remote times and places and to ultimate causes, we would have to know a great deal more about the universe than we do now to be sure that no such God exists. To be certain of the existence of God and to be certain of the nonexistence of God seem to me to be the confident extremes in a subject so riddled with doubt and uncertainty as to inspire very little confidence indeed.

Absence of evidence is not evidence of absence. As this statement applies to science, so does it apply to religion. History is replete with signs that an all-powerful deity may not exist, but such substantiation is nowhere near tantamount to proof -- especially, as Albert Einstein said, in a universe as incomprehensibly vast as our own:

The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly.

Ultimately, the key is not to be swayed to one extreme or the other -- fundamentalist religion or strict atheism -- but to walk a reasoned middle path. Eagleman believes that path is "possibilianism," the concept of holding multiple beliefs or hypotheses whilst exploring new ideas.

"The goal is to avoid committing to any particular story," Eagleman told Discovery News, "whether that's religious fundamentalism or strict atheism. The goal of possibilianism is to retain the wonder that drives us all into science in the first place and to avoid acting as though we know the answers to things we can't possibly know at the moment."

Strict atheists do the world an incredible service by promoting the scientific method, skepticism, and critical thinking. But they do a disservice by campaigning against religion or touting -- as pure truth -- the non-existence of God, for those actions (especially the latter) are just as unscientific as a blind belief in all aspects of religion.

This summer, a worldwide poll showed that atheism is on the rise and religiosity is on the decline. It is my hope that these "New Atheists" and agnostics won't narrowly focus on denigrating religion, but will instead focus on encouraging open-mindedness and discouraging fundamentalism.

That would surely make the world a more enlightened place.

(4) Methodological naturalism (MN) is not a legitimate principle to employ, when it comes to understanding the origin(s) of objects exemplifying “specified complexity.” MN arbitrarily restricts science to finding only “natural” causes, when “intelligent” causes may actually be operative in some instances. Furthermore, MN is tantamount to “methodological atheism,” and to insist on it in each and every case leads to ontological (or metaphysical) naturalism—another word for atheism.

This might be the single most important tenet of ID, even more important than (2), that the universe itself, and some of the objects that compose it (both living and nonliving), exhibit abundant evidence of having been “designed.” This is also probably the most controversial of the tenets, and in order to see why, we need to understand the meaning of methodological naturalism.

A few years ago, when historian Ronald Numbers tried to determine who coined the term (“Science Without God,” p. 320 note 2), he tentatively credited it to philosopher Paul de Vries of Wheaton College, who had used it in a paper he delivered at an academic conference in 1983 and then published three years later (see the Print References). His article is not available on the internet, but one can get a good sense of his idea and what motivated him from a commentary written by Southern Baptist theologian Hal Poe and his former student Chelsea Mytyk. De Vries stressed that MN is simply a disciplinary method that makes no claims about God’s existence, while “metaphysical naturalism” is a wider philosophical position that denies a transcendent God. Many TEs endorse precisely this distinction, whereas I cannot name any ID author who likes it. This may indeed be the single most fundamental difference between TE and ID.

It’s worth noting in passing, however, that de Vries was not actually the first person to speak about “methodological naturalism.” Several authors since the early twentieth century have used the term, though not always with the same precise meaning. Perhaps the most significant of these was theologian Edgar Brightman, a student of Borden Parker Bowne, whose philosophy of religious “personalism” influenced some important modernist Protestants from the 1920s. Brightman discussed a form of MN on pp. 213-14 of A Philosophy of Religion (1940), a work that influenced Martin Luther King, Jr.

For our purposes, though, I’ll use the definition from an article I wrote with philosopher Robin Collins (who was at the time a Fellow of The Discovery Institute). We defined MN as “the belief that science should explain phenomena only in terms of entities and properties that fall within the category of the natural, such as by natural laws acting either through known causes or by chance.” This is to be distinguished from “ontological naturalism” (or “scientific naturalism”), “the claim that nature is all that there is and hence that there is no supernatural order above nature,” plus “the claim that all objects, processes, truths, and facts about nature fall within the scope of the scientific method.”

Ever since the Pre-Socratic philosophers, scientists and physicians have insisted on giving “natural” explanations for “natural” phenomena, leaving miracles explicitly out of science. Christians have done likewise, going back at least to the high Middle Ages if not earlier. It would be easy to cite many “big name” examples, including Johannes Kepler and Robert Boyle. Readers who want to know more about this are invited to consult the essays by Numbers and Davis & Collins in the appended list of references. I’ve also seen several more examples in an excellent essay on the topic of God and MN by a Christian philosopher (whose name does not appear anywhere in this column), but it would be inappropriate for me to cite it before it’s been published.

This doesn’t mean that no scientists believe in miracles; quite the contrary—probably tens of thousands of American scientists (including many TEs) believe that miracles are possible and that some have happened. They simply don’t believe that miracles can be part of scientific explanations. Even proponents of the YEC view don’t invoke miracles in what they call “operation science” (or “experimental science” or “ordinary science”), reserving them only for “origin science” (or “historical science”). (See my discussion of this distinction in "Galileo and the Garden, Part 2".)

According to mainstream science (including most advocates of TE), scientific explanations are “natural” explanations; they can’t invoke the “supernatural,” i.e., God or the gods or miracles. To some extent, I think that ID cannot entirely escape this problem, as I explained in my previous column. However, another important distinction poses “natural” causes vis-à-vis “intelligent” causes, which are not necessarily “supernatural.” We all know, for example, that skyscrapers don’t come about “naturally,” but they require “intelligent” causes to design them. The real question is whether any “natural” objects—such as galaxies, rocks, trees, or people—also require “intelligent” causes to design them and, if so, whether such causes should be part of any scientific explanations of those objects. Dembski’s idea of “specified complexity” and Behe’s idea of “irreducible complexity” come into play just at this point. ID proponents believe that the scientific toolbox needs to include “design,” an explanatory tool that includes rather than excludes intelligent causation as part of the explanation for how certain things came into existence. Their opponents think the scientific toolbox is large enough as is, without adding “design” to the set.

This is a difference of opinion about the nature of science itself. As a philosophical argument, it’s not likely to be settled by appeals to bacterial appendages or the Cambrian explosion or pseudogenes in humans and chimps. Prior to the Scientific Revolution, “design” was generally accepted or assumed within science. During the Scientific Revolution, a split began to take place, as some scientists argued that invoking design had no scientific benefit (design might explain why we have something, but now how it works), even though almost all of the early scientists were Christians who fully accepted the reality of a God who had, in fact, designed all of nature. By around the middle of the 19th century—coinciding with Darwin, who sought to make biology look more like physics and astronomy, disciplines in which unbroken “natural laws” already held sway—design largely disappeared from scientific discourse.

NOTE: Contrary to what is sometimes said, natural theology did not disappear after Darwin. Scientists themselves (not just philosophers and theologians) continued to contribute to it, right down to our own day (Polkinghorne is an obvious example). It’s simply that one no longer expects to find “God” or “design” (in the transcendent sense that is clearly meant by ID proponents) in scientific literature.

There are probably several reasons for this development, but I’m not confident that I understand them well enough to talk about it here. For our purposes, it’s enough just to state that ID proponents want to reverse this history. As William Dembski has written, “The scientific picture of the world championed since the Enlightenment is not just wrong but massively wrong.” What is the root problem? “Naturalism is the intellectual pathology of our age. It artificially constricts the life of the mind and shuts down inquiry into the transcendent.” ID, on the other hand, is “the only alternative” to naturalistic evolution, and in order for it to succeed we must “dump methodological naturalism. We need to realize that methodological naturalism is the functional equivalent of a full-blown metaphysical naturalism. Metaphysical naturalism asserts that nature is self-sufficient. Methodological naturalism asks us for the sake of science to pretend that nature is self-sufficient.” (Intelligent Design, pp. 224, 120 and 119, his italics)

Advocates of ID challenge both forms of naturalism at every opportunity. In their view, MN is really nothing but “methodological atheism,” another term that rose to prominence in the debate about ID but also originated earlier. (It might have been introduced by sociologist Peter Berger in the late 1960s.) According to Phillip Johnson, the founder of the ID movement, “Methodological atheism and [the world view of] naturalism are identical.” (Reason in the Balance, note on p. 99, his italics) Thus, some ID thinkers—especially the evangelical philosophers Alvin Plantinga, Steven Meyer, and J. P. Moreland—have made the case for rejecting MN in favor of what Moreland calls “theistic science” or Plantinga calls “Augustinian science”. Another evangelical philosopher, Robert O’Connor, offers a vigorous defense of MN. Many other Christian scholars have weighed in on this; some examples are among the links assembled here. (In passing, let me note that most of these articles were published in the ASA’s journal. This belies the charge sometimes made by ID advocates that the ASA is unfriendly to their position; I think this simply reflects frustration that more ASA members have not found ID sufficiently persuasive.)

So—is MN in fact equivalent to atheism? That’s the rock bottom question here, and there simply is no consensus—neither among Christians nor even among atheists, for that matter. I defended it myself several years ago in a brief exchange with Phillip Johnson, who had written a letter in reply to my review of three ID books, including one of his, which ran as a cover story for Reports of the National Center for Science Education.

Let me give the final word to Loren Wilkinson of Regent College, whose short article, “Does Methodological Naturalism lead to Metaphysical Naturalism?” should not be missed:

“What is at issue, therefore, is not the fact of an elusive and ultimately unattainable scientific description [a complete scientific description of the origin and development of living things], but rather whether the ideal of such a description is incompatible with the loving, personal, creator God revealed to us in Scripture and in Jesus Christ. Yet the ideal that complete understanding of a process excludes God from the picture contradicts our normal Christian practice. We regularly, for example, thank God for our food: rightly recognizing it as God’s provision. Yet we could, if we took the effort, trace the corn or tomato back through many manmade and ‘natural’ processes to its source. The practice of the ‘methodological atheism’ of going regularly to the store (or the garden) to obtain such food does not necessarily produce ‘metaphysical atheism’ in the eater, who still ought to thank God for his provision.” (Darwinism Defeated? pp. 169-70)

It’s your turn now to weigh in. I hope your comments will reveal some familiarity with the books and articles I’ve mentioned, but of course there are so many others that I failed to mention—in which case I hope you will introduce all of us to them. HAPPY THANKSGIVING to my American readers, and best wishes to all.

Looking Ahead

I’ll be back in about two weeks, to discuss some conclusions we might draw about ID.

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

—Hamlet Act 1, Scene 5

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

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

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

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

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

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

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

The human condition

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

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

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

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

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

A biblical model

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

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

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

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

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

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

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

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

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

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

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

Science and Technology are powerful forces in our modern world. Innovations in transportation, communications, agriculture, and medicine have dramatically improved the quality of human life. On the other hand, science and technology have also made it possible to destroy life on an unprecedented scale through instruments of modern warfare. It’s no wonder then that science evokes a wide range of emotions—from praise and hope to fear and distrust. In addition to a wide array of applied technologies, science also has unique explanatory power: it has revealed the immense age of the universe, the history and development of life, and the delicate balance of our environment. Science inspires us and challenges us, and like it or not, it continues to shape our lifestyles and self-understanding.

Given the diverse attitudes towards science in our country, it is important that we ask the question, “What exactly is science?” Does it give us absolutely certain knowledge? Is science truly objective and value-free? Does it eliminate purpose from the universe? Are there any limits to science?

This essay seeks answers to these questions. We will investigate them first by formulating workable definitions about what science is. Here in this post, we will focus on the philosophical and ethical foundations of science. In the next post, we will examine the goals and limits of science. In doing so, we will find that science is not a rigid, impersonal assemblage of facts, but a dynamic and distinctly human enterprise.

Defining Science

Mariano Artigas

What is science? Many authors have labored over this question, but the Spanish physicist and philosopher Mariano Artigas has offered a particularly insightful three-pronged definition:¹

1. Science is a goal-directed activity towards the knowledge and control of nature

As a goal-directed activity, science itself has purpose—it strives towards a more complete understanding of nature and the ability to modify it to serve human needs. These goals are understood to be valuable and worth the painstaking efforts necessary to achieve them. In these respects, science has values at its very core.

2. Science is a well-defined method

Another essential component of science is its method. Both Artigas and physicist Ian Hutchinson maintain that the scientific method defines science itself. Hutchinson singles out two particular characteristics that distinguish it from other forms of intellectual inquiry.² First, science relies upon experimental or natural evidence. Ideally, this evidence should be reproducible and thus subject to verification by other researchers. (Note: in some fields such as astronomy where one cannot actually reproduce events that take place many light-years away, one can make numerous observations as a basis of comparison. In disciplines such as the life sciences, biologists can rely on a multiplicity of specimens to approximate the need for reproducibility.)

Second, besides requiring a particular kind of evidence, the scientific method also demands certain types of explanations. They should be mathematical, mechanical, measurable, or quantifiable in some way. For example, one can take measurements of mass, number, length, time, velocity, pressure, volume, or many other discrete units. The goal is to create unambiguous results that are capable of creating consensus among other researchers, and understandable by anyone else who carefully investigates the topic.

3. Science is a body of knowledge

With these three dimensions of science firmly in mind, we have the basis for distinguishing science from non-science.³

Philosophical Foundations of Science

Despite its day-to-day reliance on empirical and measurable data, science rests on certain assumptions about knowledge itself that cannot be empirically proven. These basic premises are what allow us to ask scientific questions in the first place. While the lack of complete certainty is perceived by critics as a weakness, the dynamic nature of science is actually a great strength⁴— since scientific presuppositions are not set in stone, new discoveries produce feedback that enables us to reassess, and if necessary, modify our assumptions.⁵ Furthermore, our understanding of natural phenomena can improve dramatically over time provided that we first accept that “understanding” is possible in principle. With that in mind, let’s investigate some of the implicit premises that undergird the scientific enterprise and speak to the knowability of the world.⁶

Realism

Setting aside various nuances, realism basically maintains that there is a world that exists outside our minds. While this may seem self-evident, it is exceeding difficult, if not impossible, to demonstrate. Everything that we have ever experienced is mediated through our minds, and while we can imagine that an external world is stimulating our senses, the fact remains that we are still thinking about it. Plato and Descartes have famously wondered whether our lives are just a continuous dream, and in our own culture, the movie Inception explored this very same question. In a related way, the movie The Matrix invited us to consider whether our “reality” was just a computer simulation designed to placate us.

Philosophers have debated this topic ad nauseum, but scientists, in order to do their work, must suppose that there actually is an external world—otherwise, they would only be chasing dreams and illusions. The challenge of science is to figure out what the universe contains and how it works, not whether it exists at all.

Nature exhibits order and regularities

Science relies on the premise that there is some underlying order the universe that we can discover and understand. If nature were to totally reshuffle every day, none of the experiments we conducted yesterday would be reliable today, and there would be little basis for making any judgments about past or future events. Therefore, scientists depend on some degree of regularity within the universe in order to carry out their goals—namely the search for consistent patterns, structure, and organization of the physical world.

At the same time, science does not have a particular commitment to exactly what kind of order exists. Thus this presupposition is actually a flexible, accommodating principle that adapts to ongoing empirical research. Lest we think that modern discoveries have marred our conception of an ordered universe, even chaos theory and Heisenberg’s uncertainty principle have given rise to a better understanding about how nature is organized.⁷

Causality

Another distinguishing characteristic of modern science is the premise that every event is caused by another event; things don’t simply happen for no reason at all.⁸ When investigating various aspects of the natural world, scientists search for natural causes and natural explanations of those phenomena.⁹ Though this approach may seem unnecessarily constrained, it has had great success in accounting for previously mysterious terrestrial events like lightning, earthquakes, and volcanic eruptions, as well as celestial phenomena like comets, eclipses, and supernovae. On the human level, scientific research led to the development of germ theory, which has led to effective treatments for numerous diseases that used to be deadly. These are compelling practical reasons to adopt a scientific approach to natural phenomena, rather than being resigned to fate or purely supernatural interpretations of our world.

Natural laws regulate the universe

If you accept the three basic premises that there is a world external to your senses, that nature exhibits consistent and unvarying order, and that causality is universal, it follows that one can formulate natural laws that effectively describe and predict many phenomena that we encounter. In fact, describing the behavior of matter through mathematics and statistics has been enormously successful at the small scale of physics and chemistry, and computational approaches hold great promise in many fields of biology. Natural laws also help explain events on the largest scales of astronomy and cosmology.

On the other hand, human activities continue to vex us. It is notoriously difficult to predict political developments, economic fluctuations, and social movements. Some people think that this is due to fundamental uncertainties and vicissitudes of human behavior. Others think that it is “just a matter of time” before scientists uncover the laws that dictate our individual and collective decisions.

Are naturals laws completely universal in time and space, absolutely certain and inviolable? Not necessarily-- since empirical science only makes measurements at particular times and places, science itself cannot demonstrate that natural laws invariably apply to every event in the universe. Uncertainty is a central feature of the human condition, and not even science can eliminate it completely.

It should now be evident that science does not proceed from completely provable foundations. However, its fundamental principles are not arbitrary or dogmatic. The practice of science itself enables us to revisit and modify our initial premises. As Mariano Aritgas puts it, “Scientific progress provides feedback on its presuppositions—it retrojustifies, enriches, and refines them.” Science may not give us the complete certainty that many humans seek, but it does provide us with profound and remarkably reliable insights into the physical world we inhabit.

Ethical foundations

A publication of the National Academy of Sciences

We have just examined how science is grounded in a number of philosophical premises without which empirical research cannot proceed. But given how often we hear that science is purely objective and impartial, it may be surprising to learn that science also contains ethical premises. In fact, certain human values are intrinsic to the entire scientific enterprise. Research communities collectively embrace intellectual freedom, the right of dissent, cooperation, accurate communication of results, and personal responsibility for one’s claims.¹⁰ When individual practitioners or institutions circumvent these values, great damage can occur not only to the progress of knowledge, but in certain fields like biomedicine, they can endanger human life.¹¹

Science is not an activity carried out by uncaring automatons. It is a distinctly human endeavor conducted by those who believe that it is better to know than be deceived and that it is better to thrive than to suffer. Thus, to call science a strictly value-free and objective enterprise is a misnomer. Instead, it promotes distinct human values: the longing to understand the world that surrounds us, and the desire to improve and perpetuate human society.^{12, 13}

The Denisovans, an extinct hominid group that interbred with modern humans, made the news again lately with the publication of a more detailed study of their genome. One of the many interesting findings was that the Denisovans share the same chromosome 2 fusion that modern humans have. In this post, I review what we know about the origins of human chromosome 2, and then discuss the new Denisovan findings and their implications.

The origins of human chromosome 2: a brief review

Though I have discussed the evidence for a fusion event leading to human chromosome 2 before, perhaps a brief review of the evidence is in order. The human genome is made up of 23 pairs of chromosomes (for a total of 46 chromosomes). This makes us something of an oddity among living great apes, all the rest of whom have 24 pairs of chromosomes (for a total of 48). Given that there are many independent lines of evidence that support the conclusion that we share a common ancestor with other great apes, this poses something of a conundrum: how is it that our species arrived at this specific chromosome number? If we were to represent this “problem” on a phylogeny, or tree of relatedness, it would look something like this (not to scale):

Our closest living relatives, chimpanzees and bonobos, both have 48 chromosomes, as do all other great apes such as gorillas and orangutans. This pattern has one of two explanations, one of which is much more likely than the other. Either the common ancestor to these species had 48 chromosomes, and there was an event that reduced that number to 46 specifically on the lineage leading to humans (option A), or the common ancestor species had 46 chromosomes, and there were independent, repeated events that increased chromosome number in all other great ape species (option B). We can compare these options by placing the required event(s) on the phylogeny (again, not to scale):

It should be obvious that the option that requires the fewest events is the more likely one – in this case option A with an event that reduces chromosome number in the lineage leading to humans. The other option, that of repeated, independent events to increase chromosome number, remains a formal, but unlikely, possibility. Events that reduce chromosome number are not frequent occurrences, so Option A is more likely than Option B.

We can also find further support for Option A, because it predicts a specific type of event, namely one that reduces chromosome number. Since loss of a large amount of chromosomal material is almost always detrimental, we need an event that reduces chromosome number without losing information. One way for this to happen is for two chromosomes to fuse together and become one. Initially, this event would produce an individual with 47 chromosomes, where two different chromosomes get stuck together. Contrary to what is often assumed, this individual would be fertile and able to interbreed with the others in his or her population (who continue to have 48 chromosomes). In a small population, over time, two relatives who both have one copy of the fusion chromosome may mate and produce some progeny with two copies of the fused chromosome, or the first individuals with 46 chromosomes. Since either a 48-pair set or a 46-pair set is preferable for ease of cell division, this population will either eventually get rid of the fusion variant (the most likely outcome), or by chance will switch over completely to the “new” form, with everyone bearing 46 chromosome pairs. While not overly likely, this type of event is not especially rare in mammals, and we have observed this sort of thing happening within recorded human history in other species. Some mammalian species even maintain distinct populations in the wild with differing chromosome numbers due to fusions, and these populations retain the ability to interbreed.

Further evidence for a fusion event in the lineage leading to modern humans comes from comparing synteny, or gene locations and orders on chromosomes within modern great apes – an issue we have discussed here before. In brief, what we see in human chromosome 2 is exactly what we would predict for a fusion event. When compared to other great apes, we see the genes on human chromosome 2 match up, in order, with two smaller ape chromosomes. We also see that sequences used at the tips of chromosomes are present at the proposed fusion site, and that human chromosome 2 has not one but two sites for the cell cytoskeleton to attach to for cell division – but that one of the sites is mutated and not functional, though it lines up precisely with the location of this site on the appropriate ape chromosome. Together, this evidence consistently supports both common ancestry for humans and great apes, and specifically that the difference we see in our chromosome numbers arose due to a single fusion event. I briefly discussed this evidence in my last post where I describe how I teach some of this material and the compelling impact it has on students exploring the evolution question for the first time.

Enter the Denisovans

With that as background, we are now prepared to appreciate a new finding that comes from genomics work done on the Denisovan hominids, an archaic species that is more closely related to Neanderthals than to us, but that nonetheless interbred with some anatomically modern humans as they migrated out of Africa and populated the globe. (For those not familiar with the Denisovans, or the evidence for our interbreeding with them, both Darrel Falk and I have written on this previously, here and here). Recently, a more detailed understanding of the Denisovan genome was published, and nested in the new information is the discovery that the Denisovans share the 46 chromosome set with the same fusion that we have. This strongly supports the hypothesis that the fusion event predates the separation of our species. If we were to represent this on a phylogeny, we can now place this event with more accuracy than before (as before, the phylogeny is not to scale):

Despite this new information, one obvious question remains. Did the Neanderthals also have the 46-pair set? From looking at the phylogeny above, we can see that the most likely answer is that they did, since the fact that the Denisovans had it strongly implies that the last common ancestor of humans and Neanderthals / Denisovans had it as well, and the Neanderthal-Denisovan split comes later. While the Denisovan DNA samples are of high enough quality to make this assessment, we do not yet have Neanderthal DNA of high enough quality to do the same analysis with current methods (though one additional feature of the new work on the Denisovan genome is developing more sensitive DNA sequencing techniques that may resolve this question in the future).

In other words, this fusion seems to be an ancient one, predating our species by several hundred thousand years. Present estimates of the last common ancestor between humans and Neanderthals / Denisovans range at about 800,000 years ago.

Implications for understanding our “becoming human”

The main implication from this work is that it places the fusion event well before the advent of our species. I’ve often chatted informally with Christians about evolution, and at times some have thought that this fusion event was what “started” our species, or made our species unable to interbreed with other groups. Some have even suggested that perhaps the fusion event was what produced the first human (i.e. Adam).

Note that thinking this way suggests a misunderstanding of how chromosome fusions occur and what effect they have on their hosts. A fusion does not precipitate a speciation event, but rather the individual with the fusion remains a part of his or her population, and able to interbreed, even if with reduced fertility. Also, there is no necessary biological effect or change that the fusion produces on the appearance of the organism. These misunderstandings aside, however,what this new evidence shows is that this fusion event took place long before modern humans arose at around 200,000 years ago. Indeed, the 800,000 years ago date for the last human - Denisovan common ancestor means that this is the most recent date possible for the fusion. While it is an interesting piece of our evolutionary history, it doesn’t seem to have much to do with how we came to acquire the traits that set us apart from, and ultimately outcompete, other similar species.

Author's Note from Joy Walters

As I mentioned in my first post, I grew up skeptical of the whole idea of evolution. One contributor to my disbelief was the lengthy timescale for the “tree of life” that was presented with the theory. I would hear, for example, that dinosaurs lived hundreds of millions of years ago, but there was no explanation of why this was true; it was just given as a fact. No one explained the methods of dating, and so I thought biologists simply estimated the ages of species to fit their preconceived notions of how long it would take for one species to emerge from another. It also seemed like the ages were periodically revised and extended farther back in time, and I figured scientists needed to manipulate numbers to make evolution plausible. This, in my mind, made the theory both unbelievable and dismissible.

Once I learned about the techniques used to date fossils, I realized that my first impressions were wrong; the ancient ages of species are scientific determinations rather than scholarly conjectures. However, I have found in recent conversations that Christians remain skeptical of old ages and the evolutionary time scale. For this reason, I wanted the videocast to address the process of fossil dating (what the methods are and why they are accurate) while focusing on cases where hominid fossils were discovered and dated using these very methods. My hope is that Believers would be informed about the evidence for human evolution and its scientific grounding.

Whereas essentialism enjoyed major position status well into the 15th century, a question that begs an answer is why essentialism has fallen upon hard times? A strong argument can be made that essentialism did not fade because it lacked evidential support, but rather with the ascendancy of naturalism in the western world, metaphysical naturalism simply could no longer tolerate the implications of essentialism. Metaphysical naturalism thins out reality, divesting it of any vertical dimension. It is rather easy to see how metaphysical naturalism, once accepted, disallows anything beyond the physical as part of any explanation of reality. In this view of reality, there is nothing that transcends experience and reality is only explained in terms of the particulars and function. The argument here is not that science does not know the physical world well (it does and all of us are beneficiaries of the knowledge), but that there is more to reality than can be measured by the instruments of science. Science is good at understanding functional matters within creation, but impotent to give answers of meaning. The claim that science provides the best framework for understanding creation begins with the commitment that all there is to reality is material. That, however, is a philosophical commitment, not something that can be demonstrated by science.

It appears that scientists in some cases, at least, have not denied the metaphysical in a Christian sense---they affirm the reality of God. Rather, it seems they have drawn a very thick line between the physical and the metaphysical, keeping reality compartmentalized. By this, they can affirm a transcendent reality but with only tangential implications for explaining the true nature of reality. Under these conditions, it is rather easy for assumptions of metaphysical naturalism to exert a subtle influence on the thinking of Christians doing science. This compartmentalizing of reality effectively translates into the idea that science is the primary agent for interpreting the truth of creation even though the transcendent is affirmed. Practically speaking, this disallows for any serious connection between that which transcends experience and how one should understand the true nature of reality—not just how it functions in our experience. This does not mean that the Bible is left out of any explanation, but only as an addendum made to fit what the tools of science have found. It is as if understanding of reality is shut up to the scientific method.

Certainly the scientific method has, as Francis Bacon promised, demonstrated amazing power to explain and understand how creation works even within metaphysical naturalism. However, it must be recognized that metaphysical naturalism comes with philosophical commitments/assumptions that themselves have not been obtained by the scientific method. For example, the assumption that all there is to reality is the material. The naturalistic assumption denies that the transcendent participates in the particular by way of essentialism. In this case, all there is, is the material where DNA and associated biological/chemical elements say everything there is to say about the nature of reality of this creation. Such commitments then limit what can and cannot be said about the nature of reality.

One’s methodical commitments often limit what one can and cannot say about reality. A case in point is Isaac Newton’s methodology. It restricted him from saying God was the cause of gravity as he said he could not form that as an hypothesis that he could later test. Of course Newton was clearly a theist, but he could not speak as a theist at this point because his scientific method would not allow it. In this way, we see how even a theist could allow his scientific methodology to exert unwarranted epistemological pressure on the work of interpreting the facts. It is precisely these commitments that can also subtly influence those doing science who on the one hand hold to theism, but on the other hand when it comes to understanding the totality of reality fail to take into account the idea of universals when interpreting the facts.

Facts are not self-interpreting. One’s interpretative processes and inferences drawn from the facts are limited to the range of possibilities his worldview sanctions. Therefore, the Christian should see how a view that God created should shape the interpretation of the facts discovered by observation. In addition, he must remember that the nature of an object determines not only what can be known about the object, but also how it can be known. One’s interpretative method must not draw a circle too tightly around creation that would, a priori, squeeze out some aspect of reality in favor of another. Whether scientist or theologian, all must think seriously about the logical extensions of beliefs as well as the influence of a priori epistemological and ontological assumptions in the interpretative process in the search for truth. It must be remembered that epistemology and ontology cannot be divided. All epistemological claims are about some piece of reality. Furthermore there is no way for science to out-of-hand reject essentialism simply because scientific tools cannot measure the claims of essentialism. To do so would entail a circular argument---all that exists is the material, science measures the material, science does not see essences, therefore all there is to reality is material.

The suggestion put forward here, however, is that essentialism is part of the explanation of why a being is what it is. That is, a being is not defined merely in biological or chemical terms. This being the case, it is necessary to discuss how or if evolution might work within a creation view of reality where essentialism is part of that view. In addition, in order to have a robust theology of Genesis 1- 3, one must realize that it was spoken into existence. This means that what came into being begins with an idea in the mind of God, an idea that determines the shape of what is. As such it has enormous ontological implications for how one understands the nature and sustainability of creation. Furthermore, whereas facts are not self-interpreting (the reality of being is more than developmental), one needs an ontological framework to guide in the interpretation of this wonderful creation as observed by humans.

This raises certain questions. As Christians, is our worldview shaped by our methodology, or does our worldview shape our methodology? If essences do not exist, then what implications would that have for the incarnation of the Word of God? Historically the church as held that Jesus had the essence of man and the essence of God. If he did not have the essence of God and the essence of human what does that mean for the Christological claims in the Bible? Furthermore, in Jesus we have two essences that remained distinct and did not emerge into a third kind giving the impression that essences do not produce new essences. Another question is whether or not Dawkins is right in his suspicion about essences and evolution? If he is wrong, we still must demonstrate why he is wrong. It seems to me that these are questions that must be answered before dismissing the claims of essentialism or the relationship between essentialism and evolution. If in the end essentialism prevails, it seems to have serious implications for evolution as Dawkins suggests. Still, we must be brave enough to follow the evidence where it leads. But it is not just the evidence that counts as so often revealed in the TV series CSI, it is the proper interpretation of the evidence. So the argument is not fundamentally over the evidence, it is over on what grounds are we justified in using certain evidence to support a particular claim. There is the work for all of us.

A Note from President Darrel Falk:

In his BioLogos post, "Come and See", Mark Noll writes the following:

Classical Christian orthodoxy as expressed in the creeds that summarize the Scriptures begins at the beginning: nature owes its existence to and is sustained by Jesus Christ. From this starting point several important ramifications follow naturally.

One is the implication that the best way of finding out about nature is to look at nature. This implication comes directly from the Christological principle of contingency (see above, 49-55). As described in the Gospels, individuals who wanted to learn the truth about Jesus had to “come and see.” Likewise, to find out what might be true in nature, it is necessary to “come and see.”

The process of “coming and seeing” does not lead to infallible truth about the physical world since there is no special inspiration from the Holy Spirit for the Book of Nature as there is for the Book of Scripture. But “coming and seeing” is still the method that belief in Christ as Savior privileges for learning about all other objects, including nature. This privileging means that scientific results coming from thoughtful, organized, and carefully checked investigations of natural phenomena must, for Christ-centered reasons, be taken seriously.

If this is true, then it behooves us to ask the question: why is there such an under-representation of Christians in the academy following the Christological mandate to “come and see?” In the study reported in the accompanying infographic, evangelical Christians are represented in the sciences at one seventh of the frequency of their representation in American society as a whole. In the nation’s most elite institutions, the situation is even more extreme. Elaine Ecklund’s recent study shows that evangelical Christians are fourteen fold under-represented in the sciences in the nation’s most elite universities.

Either Noll has the mandate wrong, or we conservative Christians are not doing a very good job of following it.

In an age that will be increasingly dominated by new biological technology, the much needed well-informed Christian scientific voice is all too silent. BioLogos exists to show that the two far-too-separate voices (Christianity and science) can speak as one—in harmony.

A scientist, my dear friends, is a man who foresees; it is because science provides the means to predict that it is useful, and the scientists are superior to all other men. --Henri de Saint-Simon¹

Scientism is a rather strange word, but for reasons that we shall see, a useful one. Though this term has been coined rather recently, it is associated with many other “isms” with long and turbulent histories: materialism, naturalism, reductionism, empiricism, and positivism. Rather than tangle with each of these concepts separately, we’ll begin with a working definition of scientism and proceed from there.

Historian Richard G. Olson defines scientism as “efforts to extend scientific ideas, methods, practices, and attitudes to matters of human social and political concern.” ² But this formulation is so broad as to render it virtually useless. Philosopher Tom Sorell offers a more precise definition: “Scientism is a matter of putting too high a value on natural science in comparison with other branches of learning or culture.” ³ MIT physicist Ian Hutchinson offers a closely related version, but more extreme: “Science, modeled on the natural sciences, is the only source of real knowledge.” ⁴ The latter two definitions are far more precise and will better help us evaluate scientism’s merit.

A History of Scientism

The roots of scientism extend as far back as early 17th century Europe, an era that came to be known as the Scientific Revolution. Up to that point, most scholars had been highly deferential to intellectual tradition, largely a combination of Judeo-Christian scripture and ancient Greek philosophy. But a torrent of new learning during the late Renaissance began to challenge the authority of the ancients, and long-established intellectual foundations began to crack. The Englishman Francis Bacon, the Frenchman Rene Descartes, and the Italian Galileo Galilei spearheaded an international movement proclaiming a new foundation for learning, one that involved careful scrutiny of nature instead of analysis of ancient texts.

Descartes and Bacon used particularly strong rhetoric to carve out space for their new methods. They claimed that by learning how the physical world worked, we could become “masters and possessors of nature.” ⁵ In doing so, humans could overcome hunger through innovations in agriculture, eliminate disease through medical research, and dramatically improve overall quality of life through technology and industry. Ultimately, science would save humans from unnecessary suffering and their self-destructive tendencies. And it promised to achieve these goals in this world, not the afterlife. It was a bold, prophetic vision.

As this new method found great success, the specter of scientism began to emerge. Both Bacon and Descartes elevated the use of reason and logic by denigrating other human faculties such as creativity, memory, and imagination. Bacon’s classification of learning demoted poetry and history to second-class status.⁶ Descartes’ rendering of the entire universe as a giant machine left little room for the arts or other forms of human expression. In one sense, the rhetoric of these visionaries opened great new vistas for intellectual inquiry. But on the other hand, it proposed a vastly narrower range of which human activities were considered worthwhile.

The Enlightenment

A century later, many of the Enlightenment intellectuals continued their love-affair with the power of natural science. They claimed that not only could science enhance the quality of human life, it could even promote moral improvement. The Encyclopedist Denis Diderot aimed to collect, organize, and preserve all human knowledge so that “our children, becoming better instructed, may become at the same time more virtuous and happy.” ⁷ Many of the French philosophes even claimed that science could be a substitute for religion. In fact, during the French Revolution, numerous Catholic churches were converted into “Temples of Reason” and held quasi-religious services for the worship of science.⁸

Positivism

The 19th century witnessed the most powerful and enduring formulation of scientism, a system called positivism. Its founder was August Comte, who built his positive philosophy from a deep commitment to David Hume’s empiricism and skepticism. Comte claimed that the only valid data is acquired through the senses. Nothing was transcendent, and nothing metaphysical could have any claim to validity.⁹ The task of scientists was twofold—first, to demonstrate how all phenomena, including human behavior, are subject to invariable natural laws.¹⁰ Second, they would reduce these natural laws to the smallest possible number, and ultimately unify them under the laws of physics.¹¹

Comte also subsumed all of human intellectual history into a single process which he called the Law of Three Stages. In his view, each branch of knowledge passes through three stages: the theological or fictitious, the metaphysical or abstract, and lastly the scientific or positive state. He believed that through the continual advancement of human understanding, religion would fade away, philosophy and the humanities would be transformed into a naturalistic basis, and all human knowledge would eventually become a product of science. Any ideas outside that realm would be pure fantasy or superstition.

Logical Positivism

Positivism did not lose its appeal in the 20th century. To the contrary, a group known collectively as The Vienna Circle reinvigorated the fundamental tenets of positivism with enhanced symbolic logic and semantic theory. They called their approach, fittingly, logical positivism. In this system, there are only two kinds of meaningful statements: analytic statements (including logic and mathematics), and empirical statements, subject to experimental verification. Anything outside of this framework is an empty concept.¹²

Given its sweeping claims, logical positivism came under heavy scrutiny. Karl Popper pointed out that few statements in science can actually be completely verified. However, a single observation has the potential to invalidate a hypothesis, and even an entire theory. Therefore, he proposed that instead of experimental verification, the principle of falsifiability should demarcate what qualified as science, and by extension, what can qualify as knowledge.¹³

Another weakness of the positivist position is its reliance on a complete distinction between theory and observation. Observations, essential to the empirical approach of science, were claimed by positivists to be brute facts which one could use to establish, evaluate, and compare the theories. However, W.O. Quine pointed out in his “Two Dogmas of Empiricism” that observations themselves are partly shaped by theory (“theory-laden”).¹⁴ What counts as an observation, how to construct an experiment, and what data you think your instruments are collecting—all require an interpretive theoretical framework. This realization does not deal a death-blow to the practice of science (as some post-modernists like to claim), but it does undermine the positivist claim that science rests entirely on facts, and is thus an indisputable foundation for knowledge.

Scientism of Today

Scientism today is alive and well, as evidenced by the statements of our celebrity scientists:

The Cosmos is all that is or ever was or ever will be. –Carl Sagan, Cosmos

The more the universe seems comprehensible, the more it also seems pointless. –Stephen Weinburg, The First Three Minutes

We can be proud as a species because, having discovered that we are alone, we owe the gods very little. –E.O. Wilson, Consilience

While these men are certainly entitled to their personal opinions and the freedom to express them, the fact that they make such bold claims in their popular science literature blurs the line between solid, evidence-based science, and rampant philosophical speculation. Whether one agrees with the sentiments of these scientists or not, the result of these public pronouncements has served to alienate a large segment of American society. And that is a serious problem, since scientific research relies heavily upon public support for its funding, and environmental policy is shaped by lawmakers who listen to their constituents. From a purely pragmatic standpoint, it would be wise to try a different approach.

Physicist Ian Hutchinson offers an insightful metaphor for the current controversies over science:

The health of science is in fact jeopardized by scientism, not promoted by it. At the very least, scientism provokes a defensive, immunological, aggressive response from other intellectual communities, in return for its own arrogance and intellectual bullyism. It taints science itself by association.¹⁵

Noting that most Americans enthusiastically welcome scientific advancements, particularly those in health care, transportation, and communications, Hutchinson suggests that perhaps what the public is rejecting is not actually science itself, but a worldview that closely aligns itself with science—scientism.¹⁶ By disentangling these two concepts, we have a much better chance for enlisting public support for scientific research than we would by trying to convince millions of people to embrace a materialistic, godless universe in which science is our only remaining hope.

Distinguishing science from scientism

So if science is distinct from scientism, what is it? Science is an activity that seeks to explore the natural world using well-established, clearly-delineated methods. Given the complexity of the universe, from the very big to very small, from inorganic to organic, there is a vast array of scientific disciplines, each with its own specific techniques. The number of different specializations is constantly increasing, leading to more questions and areas of exploration than ever before. Science expands our understanding, rather than limiting it.

Scientism, on the other hand, is a speculative worldview about the ultimate reality of the universe and its meaning. Despite the fact that there are millions of species on our planet, scientism focuses an inordinate amount of its attention on human behavior and beliefs. Rather than working within carefully constructed boundaries and methodologies established by researchers, it broadly generalizes entire fields of academic expertise and dismisses many of them as inferior. With scientism, you will regularly hear explanations that rely on words like “merely”, “only”, “simply”, or “nothing more than”. Scientism restricts human inquiry.

It is one thing to celebrate science for its achievements and remarkable ability to explain a wide variety of phenomena in the natural world. But to claim there is nothing knowable outside the scope of science would be similar to a successful fisherman saying that whatever he can't catch in his nets does not exist.¹⁷ Once you accept that science is the only source of human knowledge, you have adopted a philosophical position (scientism) that cannot be verified, or falsified, by science itself. It is, in a word, unscientific.

In part 1 of his sermon “Over and Above Naturalism”, Joseph Barkley explained that science does not reveal the greater purpose to life. He also looked at Naturalism, a philosophy that depends on atheistic assumptions and scientific knowledge, stripping the material world of higher significance. In part 2, Barkley suggests that material creation is not the end of our understanding (as Naturalists think), but a beginning that unveils the majestic and power of a Creator who loves us. Exploring the grand dimensions of the Milky Way galaxy as well as our unique solar system, he points to the greatness of God and smallness of humanity. However, the most profound truth is God’s incomprehensible love for each person that leads us into a divine relationship with him.

Barkley first suggests that all scientific discoveries, rather than confirming the absence of a God and divine purpose, affirm the presence of an intelligent God with a plan for his creation. Each new fact about nature is just another “clue,” he says, to God’s splendor. This is clearly taught in Psalm 19: 1-2 (NIV): “The heavens declare the glory of God; the skies proclaim the work of his hands. Day after day they pour forth speech; night after night they reveal knowledge.” Though some argue that Bible does not accurately describe the natural world, Barkley affirms the infallibility of Scripture in revealing truth about God and the purpose of his creation.

Barkley demonstrates his point by recounting stunning details about the Milky Way, just one of billions of beautiful galaxies. Within it, stars are birthed and others die, planets are pulled toward stars with great gravitational force, and other celestial bodies are also always in motion. He focuses on the mind-blowing detail of the galaxy’s length, which is so vast that it requires the measurement to be in light years. It is 100,000 light years wide, and each light year represents 5.88 trillion miles. What is more, the Milky Way is only a middle-sized galaxy! God rightly declares through the prophet Isaiah, “‘So—who is like me? Who holds a candle to me?’ says The Holy One. Look at the night skies: Who do you think made all this?” (Isaiah 40:25, The Message translation). As Barkley puts it, “that is the question the creation is presenting to us today—who could have possibly made all this?”

Not only does creation reveal God’s grandeur, but it also speaks of how “unimaginably small” we are in comparison. In fact, when the Voyager space probe produced sixty separate pictures to capture our solar system from 4 billion miles away, planet Earth appeared as “a little mote of dust suspended in a sunbeam,” (Figure 1) according to Carl Sagan. If our entire planet—holding the entirety of human life—appears as a speck of dust, then how much more inconsequential does humankind itself appear? This comparison helps to “right-size” humanity in relationship to God. We are infinitely small and God is endlessly vast, and yet he deeply loves us in the midst of our weakness.

Finally, creation stirs the human heart with longing to know the “who” behind the “what” in this world. For thousands of years, God revealed himself to Israel through the Law and the prophets, but when God decided to present the clearest, most perfect picture of himelf, he sent his beloved Son, Jesus Christ (Figure 2). Colossians 1: 15-17 confirms this truth of Jesus Christ: “He is the image of the invisible God, the firstborn of all creation. For by Him all things were created, both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities— all things have been created through Him and for Him. He is before all things, and in Him all things hold together.” With this, Barkley addresses the question of greater significance. A scientific mindset might lead us to search for worth in our function, but Barkley says this is a mistake. In reality, he says, we were created not just for a function, but for a person. That person is Jesus Christ, the perfect image of the Triune God. Ultimately, Barkley affirms that one could fathom all scientific knowledge and still not discover his or her own purpose, which flows only from a relationship with God through Jesus Christ.
