Many things we have learned contradicts much of what we previously thought about the mind.  For example, it is quite common and sensible to believe that we come into the world with minds that are essentially “blank slates,” and that what we know is written on those slates by experience alone.  But that view appears to be wrong.

The human mind consists of a variety of distinct and interacting mental tools, each of which comes pre-loaded with some quite specific content and some processing algorithms.  For example, it is now clearly demonstrated that human beings are naturally endowed with what we might reasonably describe as innate beliefs and innate cognitive processors.

On the belief side, developmental psychologists have identified numerous domains of understanding that are native to us, such as folk physics, folk biology, folk psychology, agency detection tendencies, and so on. What these discoveries seem to show is that our minds are pre-disposed to come to think about the world in very specific ways—ways that are determined by the kinds of minds we have.

So it looks like from birth, or rather through a regular and maturationally natural process, we have dispositions for form beliefs in the following domains.

“Folks Physics”:

• Objects move on inertial paths
• Objects cannot move through other objects
• Objects must move through space
• Objects must be supported

“Folk Psychology”:

• Agents act to satisfy desires
• Agents have beliefs

“Folk Biology”:

• Animals bear young similar to themselves
• Living things need nutrients

In addition to these innate dispositions toward certain kinds of beliefs, we also seem to have cognitive mechanisms that dispose us to crunch sensory inputs in specific ways. We might call these “innate cognitive processors.” Examples of these would include things like contagion avoidance and agency detection.

Contagion avoidance is a natural aversion human beings share to things like dead bodies, animal waste and vomit, rotting food, etc. These things “gross us out” from a very early age.  Indeed, the aversions we have towards them pre-date any data we might come to possess that would lead us to judge them dangerous.  We are also repelled by them in ways that are independent of other aversive stimuli like smell (that is, you can’t explain this aversion by noting that people are scared off because of an unpleasant odor since studies show that the aversions are independent of that).

A second processor is our Agency Detection Device. Here, psychologists have identified a cognitive processor that seems to pre-dispose us to form beliefs in the reality and presence of (sometimes invisible!) agents under certain conditions. In these cases, when we look for the cause of certain events, motions, sounds, or structures, we are disposed to think that it was caused by a someone rather than by a something. Our ADD appears to be hypersensitive.  It is very good at detecting agency, and in fact is more likely to generate false positives than false negatives.  This is often referred to as our hypersensitive agency detection device (HADD), and may be reflected in manifold attributions of ghosts, fairies, forest spirits, and even personalities of machines!

In sum, psychologists have shown that our initial presumption about the contents of our mind was wrong. Our minds are not blank slates, but processing devices that come endowed with a complex operating system.

Many are quick to point out that this should not be surprising.  When we look across times and cultures and find very similar beliefs concerning the nature of physical, biological, and psychological reality, those similarities cry out for some explanation. Since these diverse individuals have a very wide range of experience, something other than, or in addition to, common experience would seem to account for the similarities of belief. And so it is natural to conclude that there is some fundamental similarity among human minds that explains it. And recent empirical evidence has in fact confirmed this conclusion.

One type of belief that is pervasive across times and cultures is religious belief.  One is thus led to wonder whether those sorts of beliefs are among those that we are naturally disposed to believe.  One New Zealand religion scholar, Joseph Bulbulia, argues that the emerging consensus is yes: “The view of mind expressed by Descartes as composed of innate understandings given in advance of any experience has been thoroughly vindicated after sixty years of cognitive psychology. It may be that Descartes will be shown correct on another score, namely that knowledge of the Divinity is imprinted on every mind [as well]”

Bulbulia’s remark invites us to entertain three key questions:

• Is there any evidence that we are naturally disposed to religion?
• How do we explain the origin of these dispositions?
• What are the implications of such explanations for belief itself?

These will be explored in the next post.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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.

If we want to talk about God, creation, and science, where should we start? It’s easy to begin with conflict. We can claim that the rise of modern science is the root of cultural decline. We can dive right into some of the contentious questions about how the Bible and science relate to each other. We can adopt a posture of defensiveness about what Christians believe and the ways in which some people think science threatens our beliefs.

But this is not a good place to start. The place to start is the place where all good Christian theology must start: with God.

“In the beginning, God….” These are the first words of the Bible. “I believe in God….” These are the first words of the Apostle’s Creed. If we want to develop wisdom and understanding about the relation between God and creation, then we need to start with the source of everything: God.

But how do we know anything about God? And how can we say anything about God? As we go about our daily lives, we can’t converse with God in exactly the same way that we might talk with our families, friends or neighbors. We can’t touch or smell God like a patch of green grass or taste Him like an apple. We can’t see him like an image on our TV screens. In theological terms, there is a sense in which God is “hidden” to our human senses. Many great Christian thinkers, such as Martin Luther, spent a good part of their lives reflecting on the “hiddenness” of God.

It may surprise you to hear God described as “hidden.” Those of us who have been in the Church for a while often are much more familiar with talk of how God has revealed Himself to us. We seem to gravitate towards detailed and systematic explanations of what we think we can know about God. God has, of course, revealed Himself to us – or else there would be very little point in trying to speak about Him. In scripture, in the proclamation of the Church, in the created world, and most importantly, in Jesus Christ, God has made Himself known. So why start with how God is “hidden?”

The very fact that God cannot be directly perceived by our ordinary human senses tells us something important about God and creation. God is “hidden” because He is “other.” God is not a patch of grass, and a patch of grass is not God. God is not an apple, and an apple is not God. God is not a television image or painting or statute, and a television image, painting or statute is not God. God is not a human being, and human beings are not God. God is not matter, the stuff of the created world, and matter is not God.

In theological terms, God is transcendent. “God” and “creation” are not the same thing. This is a basic idea that distinguishes Christian understandings of God from many other philosophies and religions. In fact, this emphasis on God’s transcendence is one important difference between the Hebrew and Christian theologies of creation and the prevailing ideas in the ancient near eastern world of the Biblical writers. It also distinguishes Christian thinking about God and creation from some of the important ideas that are common today.

In many ancient near eastern creation myths, the material creation was derived from the body of a god. In the Babylonian Enuma Elish, for example, the female god Tiamat is killed by another god, Marduk, and the two halves of Tiamat’s corpse become the earth and the skies. In Egyptian mythology, many of the gods were related to material entities. Ra, for example, was the god of the Sun, Nut was god of the sky, and Geb was god of the earth. These stories reflect an ontology in which there is no sharp distinction between the gods and the material world. The Biblical literature, in contrast, separates the nature and being of the creator-God from the nature and being of His creation.

In contemporary popular Western culture, two of the most common ideas about God and creation really are very old notions dressed up in new clothes.

One is a thought you might hearon TV talk shows, in self-help books, or in popular music or movies: that “everything is one” or that “God is in everything and everyone.” This usually sounds like “pantheism” — the notion that God and the world around us really are essentially the same thing. In American popular culture, this often boils down to God becoming the same thing as our own individual selves. How often have you heard a line like this in a song or TV show or movie: “what you’ve been looking for has been right inside yourself all along” or “the most important thing is to find out who you are?”

The truth of God’s transcendence means that the real basis for a meaningful and good life lies outside of our selves. We are part of creation, and therefore we are not God. We must look outside ourselves to find the source of life. Before we become too critical here, we need to preview for a moment another important theme in Christian theology: that God is also immanent. It is true that creation is an interconnected system and that God is always present throughout all of creation. It is also true that in our created humanity we are made for an intimate connection with God. It is right to look into ourselves as we seek God. As Augustine described in his Confessions, an honest search of the self should reveal a nature that is not self-sufficient, that is not meant to be alone, that longs for relationship with a beauty and harmony and love that the individual self cannot sustain. Augustine called this a “God-shaped void” at the heart of every person.

Yet we also need to be clear that, while the search may begin within our selves, it must not stop there. God is “other,” so we must continue beyond ourselves, in fact beyond everything we think we see, in order to find Him. And the paradox here is that we can only find the true meaning and purpose of our own selves by going beyond ourselves and finding the God who is other than us and who made us.

The other idea often expressed in our popular culture is that “matter is all there is.” Unfortunately, for some people this idea has become the standard for supposedly “scientific” thinking about the world. But this is not a “scientific” idea at all – it is a metaphysical statement (“metaphysical” just means “beyond the physical”) with roots going back to the ancient Greek Stoics. For many educated people in Western culture, if something cannot be verified with the human senses, it is not “real,” or at least it is not worthy of consideration as a matter of “fact” or “reason.”

There are many reasons why this way of thinking about what counts as truth or knowledge has become so influential. Our modern intellectual, political and social systems were shaped by the period from the seventeenth to eighteenth centuries known as the “Enlightenment.” Even modern Christianity has been tinged in significant ways by Enlightenment thought.

The Enlightenment, of course, was not all bad. It gave us some great gifts, including the contemporary scientific method and the political frameworks, such as the U.S. Constitution, that support the freedoms we now take for granted.

But like many exciting moments in history, the Enlightenment produced some unbalanced perspectives. The ways in which human beings can know things in addition to observation of the tangible world around us were lost. The sorts of intuitions and experiences that human beings throughout history had understood to reach beyond reason were discredited. The thought that a transcendent God might have broken into history to reveal anything about Himself was mostly set aside.

Christian theology has always asserted that because God is transcendent, human observation and human reason are neither the starting point nor the ending point for true knowledge, wisdom and understanding. If matter is not all there is, then our search for truth cannot be limited to the material world alone. In fact, the beginning of knowledge and wisdom is the realization that God is beyond and other than the created world. Again, a word of balance is in order. Human observation and reason do matter, precisely because God created us as part of a world that is in important ways orderly and knowable. The great Christian thinker Anselm said that knowledge is the act of “faith seeking understanding.” “Understanding” – the sometimes difficult process of bringing all our resources, including reason, to bear on the search for truth – depends on and follows “faith.”

God’s transcendence means that the physical world does not represent the limits of what is true and real. Indeed, the physical world is not the beginning or end of what is true and real. The “beginning and end,” the “alpha and omega,” is the God who is beyond all our thoughts and imaginings.

During the past year the first results were published from the "Encyclopedia of DNA elements" project ('ENCODE'), revealing that at least 20 percent of the genome, perhaps more, is involved in regulating the expression of its 21,000 protein-encoding genes. The "selfish gene" had its day in the sun, but has now been replaced by the image of a finely tuned genomic system in which each type of gene product cooperates via an intricate networking complex to generate the music of life. The vast array of epigenetic signals whereby genes are switched on or off ensures a steady flow of two-way communication between the genome and its wider environments.

The human as a complex, interactive and highly integrated system might not on the face of it seem a fruitful hunting ground for those who see the genes as pulling the strings of life. Nevertheless, the past year has continued to see a growing love affair between the social sciences and genomics. This is well illustrated by a recent article in Nature entitled: "The anatomy of politics -- from genes to hormone levels, biology may help to shape political behavior." The author writes that "An increasing number of studies suggest that biology can exert a significant influence on political beliefs and behaviors," reporting that "genes could exert a pull on attitudes concerning topics such as abortion, immigration, the death penalty and pacifism." The political scientist John Hibbing is quoted as saying that "...it is difficult to change someone's mind about political issues because their reactions are rooted in their physiology."

Geneticists have highlighted the suspect nature of such claims from a purely scientific perspective. But in our present context it is the way that the genetic results are reported that is most striking. Note the dualist language involved and its assumption of genetic determinism. Genes and physiology are seen as something different from "us" and "our mind," and they seem to be controlling us, so we can't even change our mind. Humans are presented as pawns of their biology, puppets dancing to the tune of their genetic masters.

What has all this to do with the "big idea" concerning human identity that the Imago Dei provides? More, it turns out, than initially meets the eye. The clash of ideas here between theology and science comes not at the level of the science itself, which, in this case, remains ambiguous and disputed, but at the level of the ideological packaging of scientific ideas. To see where the clash comes from, we first need to understand the revolutionary nature of the Imago Dei idea in its original context in the texts of Genesis.

For millennia it was uniquely the pharaoh or the king who was seen as being in the "image of a god" in the polytheistic political systems of ancient Egypt and Mesopotamia. Adad-shum-ussur, a court astrologer and cultic official in the seventh century B.C. royal court of Nineveh, made clear that the Assyrian king Esarhaddon is the very image of Bel (Marduk), the top god of that era:

A (free) man is as the shadow of god, the slave is as the shadow of a (free) man; but the king, he is like unto the (very) image of god.

Richard Middleton provides further examples in his book, The Liberating Image, which describes how the stratified urban society of great cities such as Babylon was structured politically, socially and economically round the king's court and the cultic practices of temple worship of the various polytheistic deities of the city. Social destinies were unchanging because rooted in powerful creation myths. Power was in the hands of the privileged few and true freedom belonged only to the king, for only he was in the image of a powerful god.

Would Hebrew thinkers and writers have been familiar with this idea? Almost certainly, yes, since Israel had significant cultural and economic contact with both Egypt and Mesopotamia over prolonged periods, not least during their periods of exile. So how would the original readers of that wonderful theological essay, Genesis chapter 1, have understood these words?:

Then God said, "Let us make adam [humankind] in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground." So God created adam in his own image, in the image of God he created him; male and female he created them. [Genesis 1:26-27].

In its historical context, the implications were revolutionary: the kingly and priestly male roles previously allocated to the privileged few by a pantheon of gods were now being delegated instead by the one creator God to the whole of humanity, male and female. In a stroke the entire ruling and priestly structure of Mesopotamian society was delegitimized. The Imago Dei was being democratized and it was now humankind who were to be the significant players in the arena of earthly life, the mandate to rule underlying their new responsibilities. Above all, humanity was set free by the one true God to determine their own destiny, no longer under the yoke of all-powerful dictators, nor under the baleful astrological control of the moon and stars.

Yet, ever since, humans have become experts at re-enslaving themselves, refusing the responsibilities that come with free-choice and submitting instead to narratives of fate and destiny. It seems ironic that today it is not the creation myths of ancient Babylon but the ideological interpretations of biology that provide the narratives of fate, in which genes "pull" humans toward certain political views and people cannot change their minds because their convictions are "rooted in their physiology."

"It's in his or her DNA" is a new phrase becoming increasingly embedded in our language, referring to something that cannot apparently be changed. On Sept. 8, 2012, Brad Pitt was quoted by the Daily Mail as saying that "America is a country founded on guns. It's in our DNA. It's very strange but I feel better having a gun." No it's not in our DNA, Mr. Pitt, either literally or metaphorically. People have choices -- they are the prisoners neither of their genetics, nor of their physiology, nor indeed of their environments. Human beings made in the image of God are free to chart their own destiny in a way that preserves human value and dignity. On that we can leave the last word to Abraham Lincoln: "...nothing stamped with the Divine image and likeness was sent into the world to be trodden on, and degraded, and imbruted by its fellows" (Aug. 17, 1858).

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

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

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

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

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

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.

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.

1. We are a world that longs for goodness and beauty, whether we are believers or not.

2. The data from emerging neuroscience and attachment research points us to a world of goodness and beauty.

3. This same data reflects and energizes the biblical narrative. Creation itself points us to the very story God is telling.

4. One of the most integral processes—that helps us get to truth and beauty—involves the changing (and renewal) of our minds. The renewal of our minds is a subset of the renewal of everything. God is on a mission of complete renewal, albeit on his timetable.

In this mission for renewal, one of the most important aspects is the interpersonal experience of being known. We change primarily not by what we know, but by how we are known. We live in a culture that is really good at knowing things, but not so good at being known.

5. Our first reaction is likely to be, “How will knowing this stuff change me?” But the biblical narrative is not just about us as individuals, it is about a world of mercy and justice. In order for us to have mercy and justice, we don’t do it primarily as individuals, we do it as institutions. God’s renewal is not just about changing us, it is about changing everything.

Keeping History Safe

In the cold morning air with the sun not yet over the ridge, the place to begin preparation for summiting Mount Darwin is to ponder the reasonableness of miracles. Many Totalizers would like to ban miracles from university consideration and inquiry. Trouble is: human history is awash with credible people reporting miracles.

Modern academic tradition tends to try and maintain order. For historians it behooves us professionally to avoid accounts of alleged spiritual events. We find comfort in a little logical gymnastics that keeps history safe for us to wander in, a deceptively formulaic avoidance method that helps us avoid what people are telling us about extraordinary events in the past.

David Hume popularly articulated this logical gymnastics in an essay titled “Of Miracles” that was eventually printed in Enquires Concerning Human Understanding (1748). “I flatter myself,” Hume triumphantly proclaimed, “that I have discovered an argument . . . which, if just, will, with the wise and learned, be an everlasting check to all kinds of superstitious delusion, and consequently, will be useful as long as the world endures.”

His everlasting check on superstition begins with a circular argument that because miracles can’t happen, a reasonable person should not even listen to reports of them. Hume taught that though the normal job of a historian was to listen to the testimony that comes down to us from the past, there is a point at which you can close your ears. Hume knew that historical testimony can get wild, so he came up with a way to domesticate the wildness, a way to make history a zoo rather than allow it to be a jungle. His “Of Miracles” has been tremendously influential in the discipline of human history over the last two hundred and fifty years, not because his ideas are strong, but because his ideas are useful. Get rid of “superstitious delusions,” and the discipline of history can be turned from a safari into a form of home economics. Hume’s domestication of history is seductively simple. Instead of following the Aristotelian tradition of linking the credibility of hard-to-believe testimony to the credibility of the testifier, Hume recommended disregarding the testifier and focusing only on the testimony. This effectively removed the persuasive power from hard-to-believe testimony. Miracles need the credibility of an eyewitness in order to have persuasive power. Hume cut the power source from the unwanted testimony.

Essentially, Hume adopted the modeling technique that Darwin later used and is best seen in Global Positioning System (GPS) units. Hume recommended gathering testimony from the past and every region to create a general model of what humans generally experience. Using this mass of information, one should generalize standards of common experience. Now if anyone reports a miracle, the alleged event can’t be true because it does not conform to the generalized standards of common experience. (Of course, Hume had already refused to allow that any reports of miracles could be used even to generalize common experience.) It’s tricky. Its logic is circular. But it works to weed out awkward, quirky information. It is as if a domineering GPS unit created a sphere to serve as an abstraction for the earth, then insisted that the earth can’t have wobbling poles and flattening in the upper latitudes because the sphere in the GPS shows it can’t be true. Given a useful and trustworthy GPS, don’t listen to a scientist who might tell you something different than what the GPS tells you.

The circularity of this argument has been noted ever since Hume first proposed it, but Hume was a good writer and said what a lot of people wanted to hear. Miracles are impossible so miracle reports can’t be true. Don’t even listen to reports of them.

Balancing Likelihoods

Also embedded in Hume’s essay is the awkward “rule of logic,” most often called “Balancing Likelihoods.” By combining math and logic in an odd way, Hume’s “Of Miracles “ offered another way for historians to avoid thinking about miracles. Balancing Likelihoods has many names but is probably best stated by David Hackett Fischer, in his Historians’ Fallacies: Toward a Logic of Historical Thought, as “the rule of probability:”

“[A]ll inferences from empirical evidence are probabilistic. It is not, therefore, sufficient to demonstrate merely that A was possibly the case. A historian must determine, as best he can, the probability of A in relation to the probability of alternatives. In the same fashion he cannot disprove A by demonstrating that not-A was possible, but only by demonstrating that not-A was more probable than A. This is the rule of probability.”

This seems to be practical but is impossible. Balancing Likelihoods, in the way described by Fischer, cannot be used by historians in any normal practice. It is a talisman to keep history mentally safe from the wildness that is reported to exist. Logicians, especially mathematicians, have long criticized intellectual constructions like this. The “probability” that Fischer writes about is seemingly mathematical, but the math is simply implied to give a sense of strength to human feelings.

Before Hume wrote “Of Miracles” probabilistic logic had been advancing rapidly and there was a great hope that mathematical analogies would strengthen human thinking—even Christian apologetics. “Pascal’s Wager,” the most famous mathematical apologetic from the seventeenth century, equated eternal salvation with mathematical infinity and then applied it to a gambling formula. Antoine Arnauld, in The Port-Royal Logic (1662), and John Locke, in his Essay Concerning Human Understanding (1690) and Discourse on Miracles (1706), carried probabilistic math and logic into the handling of reported miracles. A half-century later, however, Hume reacted against Arnauld and Locke’s teachings that mathematical analogies could help in the discussion of the credibility of miracles. Hume insisted that to handle a reported miracle, a historian had to create two separate ratios, pro and con, for believability. The ratios were then to be weighed against each other. This is Fischer’s “rule of probability” quoted above. In the language of Hume’s era, this was proclaimed as the “calculus of good sense.”

Lorraine Daston, in Classical Probability in the Enlightenment (1988), offers an excellent study of Hume and the many eighteenth-century mathematicians who wanted to help bring rigorous quantitative thinking to what today would be called the humanities. Daston writes that by the 1840s, mathematicians realized that “the ‘calculus of good sense’ had become antithetical to good sense,” and that today most of what these early probabilists were trying to do is considered “patently absurd.”

In 1901, one of America’s preeminent philosopher-mathematician-logicians, Charles Sanders Peirce, wrote three essays attacking the way historians had adopted Hume’s bad logic: “A Preliminary Chapter, Toward an Examination of Hume’s Argument Against Miracles, in its Logic and in its History,” “Hume’s Arguments Against Miracles, and the Idea of Natural Law,” and “On the Logic of Drawing History from Ancient Documents especially from Testimonies.” Peirce showed that historians are in error when they talk of judging testimony by balancing probabilities because “in a scientific sense, there are no ‘probabilities’ to be judged.”

Probability, Peirce wrote, “is the ratio of the frequency of occurrence of a specific event to a generic event.” A testimony “is neither a specific event, nor a generic event, but an individual event.” Peirce further pointed out that what people were justifying by claiming Balancing Likelihoods was really simply relating “what they prefer to do” to what they don’t prefer. “Likelihood is merely a reflection of our preconceived ideas.”

Historians like me who teach in universities about the reasonable credibility of Jesus’ resurrection need to be students of Peirce not Hume on the subject of assessing the credibility of reports that come down to us from ancient history. Dealing wisely with reports of events verging on the incredible is just part of the normal job of being grounded in the social study of our complex human past.

“Come to history as a doubter,” Richard Marius advises in a historical methods manual. “Skepticism is one of the historian’s finest qualities. Historians don’t trust their sources. . . . Nothing is quite so destructive to a historian’s reputation as to present conclusions that prove gullibility.”

But Marius is wrong. In practice, historians have to trust more than doubt. In practice, historians, especially ancient historians, can’t rely on doubting. Historians have to be close listeners, discerning listeners, wise listeners, who sometimes have to make harmonies and stretch for belief.

There are several different kinds of arguments that people bring along these lines; I want to talk about just one. So first… the Heidelberg catechism, one of the forms of unity of the church I go to (the Christian Reformed Church), says

Providence is the almighty and ever-present power of God, by which he upholds as with his hand heaven and Earth and all creatures and so rules them, that leaf and blade, rain and drought, fruitful and lean years, food and drink, health and sickness, prosperity and poverty. All things, in fact, come to us not by chance, but from his fatherly hand.

And part of the way it comes to us—not by chance, but from his fatherly hand—part of the way God has designed our world, is that there is a great deal of regularity and dependability in our world. Of course, if it were not for this regularity and dependability, we couldn’t do the things that we actually do. I mean, for example, if I just wanted to walk off the stage—if, for example, all the sudden those stairs over there suddenly turned into a ladder going up—well, that would make it really difficult.

If you are trying to build a house, for example, you have this hammer, but all the sudden the hammer turns in to a goose or a pigeon. Again, that would make things really difficult…or if the nail turned into a worm…or if you get in the car and turn the key and the car turns into a camel, things would be really hard, much harder than they are. This regularity and dependability in our world is an essential condition of our being able to live in the world in which we actually do.

If the world were irregular enough, we would not even be able to live in it, but there are also, according to classical Christianity here (the Heidelberg catechism, for example) there are also special divine actions; sometimes God does things specially. There are miracles in Scripture: the parting of the Red Sea, for example, Jesus walking on water, Jesus changing water into wine. There are miraculous healings: Jesus rising from the dead, Jesus raising Lazarus from the dead, and so on. And according to classical Christians, many of them, perhaps most of them, are special divine actions. God, for example, responds to prayers. He works in the hearts and minds of his children to effect sanctification. There is, what Calvin called, the internal testimony or witness of the Holy Spirit, and there is what Thomas Aquinas called the internal instigation of the Holy Spirit. So, these things are all special actions on the part of God. God constantly causes events in the world. Ok, so far fair enough—what is the problem?

Many theologians seem to think there is a science-religion problem here. I don’t think any of the theologians of Biola think this, (I don’t know, but I doubt it) but many theologians do. For example, Rudolf Bultmann says, “The historical method,” which of course he thinks that is the method we should use, “includes the presupposition that history is a unity in the sense of a closed continuum of effects in which individual events are connected by the succession of cause and effect. This continuum, furthermore, cannot be rent by the interference of supernatural, transcendent powers.”

That’s what he says. Alright, there is this continuum that cannot be rent by the interference of supernatural (that would be God) or transcendent powers. So, it is a little bit like the laws of the Medes and Persians. You probably remember Daniel. Daniel was a favorite of King Darius, and well, the other courtiers became jealous of Daniel (they didn’t like it that the king liked him so well). So, they came to the king and said, “Oh king, live forever, we think it would be a great idea if you passed an edict to the effect that you alone can be worshipped. Everybody has to worship you and nothing else.” Well the king thought that over for a minute, and that sounded pretty good to him so he said, “I guess that it is a pretty good idea.” So he made this edict; he made this declaration: “Only King Darius is to be worshipped—no one else, nothing else.”

These courtiers knew that Daniel worshipped God, and they thought probably Daniel would keep right on worshipping God despite this edict. So they were watching Daniel, and he was, in fact, worshipping God. So they came to the king. Now the penalty for worshipping something else was to be thrown into the lion’s den and they said, “Well, king live forever, looks like Daniel has been violating this edict. You have got to throw him in the lion’s den.”

Well, the king didn’t want to do this because he really liked Daniel. He thought this was a miserable way to proceed, and he didn’t want to do it, but then they said to him, “O king live forever, and remember a law of the Medes and Persians cannot be abrogated, even by the king himself.” So once it’s put in place, not even the king himself can change it or abrogate it or go against it.

That is sort of the suggestion that you get here from Bultmann. Bultmann thinks, “Maybe God created the world and set it up in a certain way, but once he did that, not even he can interfere in it”—he uses that word interference—“not even he can do anything in it. He just has to keep hands off.” It is like the law of the Medes and the Persians.

Another theologian who agrees is John Macquarrie, who says,

The way of understanding miracle (and that would be one kind of special divine action) that appeals to breaks in the natural order and to supernatural intervention belongs to the mythological outlook, and cannot commend itself in a post-mythological climate of thought. The traditional conception of miracle is irreconcilable with our modern understanding of both science and history. Science proceeds on the assumption that whatever events occur in the world, can be accounted for in terms of other events that also belong within the world, and if on some occasion, we are unable to give a complete account of some happening, the scientific conviction is that further research will bring to light further factors in the situation that will turn out to be just as imminent and this worldly as the factors already known.

Ok again, no room there for special action. And the third thinker here, Langdon Gilkey (still another theologian), says something similar, but I will pass. I will not read that one in the interest of saving a little bit of time, but these three theologians, plus many others want to assert that there is something wrong with the idea of God acting in the world, acting in the world in a way that goes beyond creation and sustaining, or creation and holding things in existence. So they think, “Ok, God created the world; God sustains it in existence”…that is ok with them, but anything beyond that, God performing any miracles, raising Jesus from the dead, or for that matter working in somebody’s heart and mind in a special way, that, they say, is a real problem. The question is, what is the problem?

Well, the next little bit here…according to the Christian and theistic idea, God is a person; he has knowledge, loves, and hates. He has aims and ends. He acts on the basis of his knowledge to achieve his ends. He is all-powerful, all-knowing, and wholly good. Thirdly (noted above by the Heidelberg catechism), God has created the world. Fourth is God conserves and sustains and maintains in being this world he created, but fifth, at least sometimes, God acts in a way going beyond creation and conservation in miracles, but also in his providential guiding of history, his working in the hearts of people, his internal instigation of the Holy Spirit, and so on, and it is with that fifth category that these people have a problem. It is God’s special action in the world—action beyond conservation and creation—and miracles would be an example.

So we might think of these theologians as endorsing what we could call hands off theology. God has got to keep his hands off. God could create the world. God conserves the world, sustains it in being, but he can’t do anything else—that is as far as he could go. It is hands off theology, and Bultmann, even in this context, even talks about interfering. I mean if God did something in the world that would be interfering, which, when you think about it, is a sort of strange thing to say—I mean if God created the world, he is the omnipotent, omniscient, holy, good creator of the world—when you accuse someone of interfering, you are saying they are doing something they should not be doing, right?

So Bultmann thinks if God did something in the world that would be interfering, and he should be ashamed of himself. Ok, now why is this a problem? Their suggestion is that somehow it is contrary to science. It is contrary to science the suggestion that God acts specially in the world. I didn’t read that bit, but Gilkey says, "The causal nexus in space and time which the enlightenment science and philosophy introduced into the western mind is also assumed by modern theologians and scholars. Since they participate in the modern world of science, both intellectually and existentially, they can scarcely do anything else.”

From a presentation sponsored by Biola University’s Center for Christian Thought, and delivered February 12, 2012 at EV Free Church, Fullerton, CA. Used by permission.

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

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

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

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

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

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

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

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

Let me be clear. I do not reject dualism on account of any kind of philosophical or other kind of argument. In fact, I find many arguments against dualism—philosophical and otherwise—to be pretty weak specimens. I’m what a friend calls an antecedent materialist. In other words, I come to the discussion assuming I am a physical object, since that is what I have always seemed to myself to be for as long as I can remember. A non-physical soul doesn’t explain anything about consciousness that cannot be explained without it, and it is furthermore a wholly unnecessary hypothesis for many religious doctrines, despite intuitions to the contrary by many religious believers. For example, belief in an afterlife, belief in the peculiarly Christian idea of the incarnation of Christ, as well as the belief that we human beings bear the image of God—none requires belief in a non-physical soul in order to be made sense of. So until I am confronted with some knock-down, drag-out argument to the contrary, or until I am presented with some phenomena that cannot be accounted for in naturalistic terms or, yet again, until I have something resembling a conversion experience that forces me to renounce my physicalism, I'm sticking with it.

To go a bit further, let’s consider several theological doctrines that seem to cut against a physicalist conception of human personhood. These constitute perhaps the three most common objections Christian physicalists receive to their physicalism. After I address these objections, I will say a little more about the content of my own physicalist conception of human persons, The Constitution View. Perhaps in a future post I can say a little bit about the science of consciousness itself and address some of the most common objections to physicalism based on that mysterious phenomenon.

Theological Objections to Physicalism about Humans

The Incarnation of Christ

The doctrine of the incarnation of Christ is a central tenet of Christianity, and it may seem that the doctrine is inconsistent with a physicalist conception of human personhood. Yet I believe a physicalist view of human persons—like my own—actually makes better sense of the incarnation than does dualism. Let me explain.

The putative problem for the physicalist is this: if God (or the second person of the Trinity in particular) is essentially a non-physical being, then how could such a being become purely physical without losing an essential property? And if the second person of the Trinity loses an essential property, then wouldn’t he not simply cease to be fully God but simply cease to exist? (An essential property is a property a thing has and can’t lack without ceasing to exist. For example, my dog has the property of being a canine. He can’t lose that property without ceasing to exist—he is essentially a canine.)

Well, according to the Chalcedonian formulation, the incarnate Christ is one Person with two natures, a fully divine nature (that of the Second Person of the Trinity) and a fully human nature (that of Jesus from Nazareth). The Constitution View I hold divides things just where one would expect—between the human nature and the divine nature of the single person. And keep in mind, by the way, that the person of Christ is not human; he is divine, being the second person of the Trinity. But this one person, in the incarnation, had two natures--human and divine. In this understanding of the dual natures, Christ is wholly non-physical in his divine nature and wholly physical in his human nature. Now consider the somewhat-awkward cleavage Substance Dualists must offer. According to Substance Dualism, Christ is wholly non-physical in his divine nature and partly physical and partly non-physical in his human nature. Not especially elegant. To my mind, far from being unable to accommodate the doctrine of the incarnation, my physicalist view of human persons is actually better able to explain the doctrine than is dualism.

Notice that if what I said above is true, the way this objection is often put contains an important mistake in assuming that the second person of the Trinity ceased to be something he was apart from the incarnation. Indeed, the second person of the Trinity did not become purely physical (or even partly physical!). The second person of the Trinity did not give up non-physicality in the incarnation. Remember: one person (Divine and non-physical) with not one but (in the incarnation) two natures—one non-physical, the other physical. How can that be? I don’t have the slightest idea; but, the mystery of the incarnation is not explained away by any account, be it dualist or physicalist.

The Imago Dei

Now, what of the imago Dei or image of God? If it’s true that we human persons are wholly physical beings—as any version of physicalism must claim—then what does it now mean to say that we have been created in God’s image? Doesn’t having been created in the image of God just mean having a non-physical soul and the features of intellect, will and emotion that characterize soul? I do not believe that our having been created in the image of God means that we are non-physical as God is non-physical. What then does it mean?

Well, there are many ways of understanding the claim that we human beings image God. One might mean that we image God when we care for Creation and contribute to the terrestrial flourishing of the Created order. This, after all, is what the Bible means when it speaks of our having been given “dominion”. We are God’s vice-regents, as it were. To have dominion is to care for others, including non-human “others” like oceans and streams, octopus and salamander; in other words to have dominion is tend to the well being of all the earth. Second, one might mean that we image God when we live in loving relation to other human beings and invest ourselves in their flourishing and well being. For we are essentially persons-in-relation. Since God is a Trinity, it is not surprising that we should image God in virtue of our essentially social nature. The tenor of the relation between the three persons of the trinity is one of a harmonious and free exchange of love and joy. So engaging in acts of mercy, hospitality, love, kindness, etc. is to act like God. In fact, we image God when we image Jesus, who welcomed the outcast, fed the hungry, clothed the naked, hated evil and delighted in doing the work of the Father. Finally, one might claim that we image God in our suffering. God is love. To love is to open oneself up to suffering. And suffering love is God-love.

Now of course none of these ways that I have mentioned that we image God rules out the possibility that we are wholly or partly non-physical beings; but it doesn’t imply it either. The fact that we have been created in the image of God is perfectly compatible with the claim that we are wholly physical beings. Indeed, there is nothing in the doctrine of the imago Dei, rightly understood, that entails a dualist view of human nature.

But even if neither the doctrine of the incarnation nor the doctrine of humanity as reflecting the imago Dei require that we be at least partially non-physical beings, what about the issue of life after death? I’ll address that third challenge to a Christian physicalism tomorrow.

Yet it doesn’t follow that we are mere animals, and our rationality is what sets us apart from the rest of the genus. Indeed, for Aristotle, and for Aquinas after him, rationality is unlike our other capacities in having an essentially immaterial and non-bodily aspect. The reason has to do with our capacity to form abstract concepts, which underlies all our other distinctively rational activities. It is because you can grasp what it is to be a man -- not just this particular man or that one, but any possible man, man as a universal -- that you can go on to form judgments like the judgment that all men are mortal, can reason from that judgment together with the judgment that Socrates is a man to the conclusion that Socrates is mortal, and so forth.

There are several arguments that establish that this capacity for abstract thought cannot in principle be reduced to or otherwise entirely explained in terms of brain activity, even if brain activity is part of the story. The arguments have their roots in Plato and Aristotle and have been defended in recent years by Aristotelian philosophers like Mortimer Adler, John Haldane, David Oderberg, and James Ross.¹ Answering the various objections to (and misunderstandings of) these arguments takes some work, but the basic idea can be set out fairly simply.²

Let us take as an example the thought that triangles have three sides. For that thought (or any other) plausibly to be material, it would have to be identifiable with something like a symbol or set of symbols encoded in the brain -- something analogous to the symbols encoded in the electronic circuitry of a computer. But there is no way a thought could be entirely reducible to that sort of thing. For no material symbol could possibly have the determinate or unambiguous content that at least many of our concepts have; and no material symbol could possibly have the universal reference that our concepts have.

Consider the most unambiguous symbol of triangularity there could be -- a picture of a triangle, such as the one to the right. Now, does this picture represent triangles in general? Or only isosceles triangles? Or only small isosceles triangles drawn in black ink? Or does it really even represent triangles in the first place? Why not take it instead to represent a dinner bell, or an arrowhead? There is nothing in the picture itself that can possibly tell you. Nor would any other picture be any better. Any picture would be susceptible of various interpretations, and so too would anything you might add to the picture in order to explain what the original picture was supposed to represent. In particular, there is nothing in the picture in question or in any other picture that entails any determinate, unambiguous content. And even in the best case there is nothing that could make it a representation of triangles in general as opposed to a representation merely of small, black, isosceles triangles specifically. For the picture, like all pictures, has certain particularizing features -- a specific size and location, black lines as opposed to blue or green ones, an isosceles as opposed to scalene or equilateral shape -- that other things do not have.

Now what is true of this “best case” sort of symbol is even more true of linguistic symbols. There is nothing in the word “triangle” that determines that it refers to all triangles or to any triangles at all. Its meaning is entirely conventional; that that particular set of shapes (or the sounds we associate with them) have the significance they do is an accident of the history of the English language. But something similar could be said of any material symbols whatever. Even if we regarded them as somehow having a built-in meaning or content, they would not have the universality or determinate content of our concepts, any more than the physical marks making up the word “triangle” or a picture of a triangle do. But then the having of a concept cannot merely be a matter of having a certain material symbol encoded in the brain, even if that is part of what it involves. Nor can it merely be a matter of having a set of material symbols, or a set of material symbols together with certain causal relations to objects and events in the world beyond the brain. For just as with any picture or set of pictures, any set of material elements will be susceptible in principle of alternative interpretations; while at least in many case, our thoughts are not indeterminate in this way.

We might understand the point by analogy with sentences. If you are going to use the English sentence “Snow is white,” you are typically going to have to express it via some material medium -- ink marks, pixels, sound waves, or what have you. All the same, the meaning of that sentence cannot be accounted for in terms of any of the physical properties of those media. There is nothing in the shapes of the letters that make up the words of the sentence, or the chemistry of the ink in which they are written, or the physics of the compression waves in the air that you generate when uttering them, that makes them refer to snow or to whiteness or indeed to anything at all. A sentence is a seamless unity of the material and the immaterial, and it is created by another seamless unity of the material and immaterial -- a human being.

At this point there will no doubt be those who object that positing ectoplasm or spook stuff is hardly a better explanation of thought than an appeal to brain activity is. And that is quite true. But then, I said nothing about ectoplasm or spook stuff in the first place. When a mathematician points out that it is just muddleheaded to speak of the square root of 25 as if it were a kind of physical object, it would be silly to accuse him of believing that the square root of 25 is made out of ectoplasm or spook stuff. If your picture of reality cannot accommodate numbers alongside physical objects, that is your problem, not his. Mathematics simply provides a powerful example of a body of truths that cannot be captured in the language of physics, chemistry, neuroscience, and the like.

Similarly, to point out that whatever a thought is, it cannot in principle be reduced to the physical properties of brain activity, is simply to provide another example of an aspect of reality that cannot be entirely captured in such language. Only if we assume that all of reality must be so captured will this sound odd, but that we should not assume this is, of course, precisely the point. And if we do assume it, we are doing so in the face of the evidence, and not on the basis of the evidence. For it is precisely what we know about thought from our everyday familiarity with it -- such as the fact that it sometimes has a determinate content, and a universal reference -- that tells us that it cannot be entirely material, just as it is what we know about numbers from our everyday familiarity with them that tells us that they cannot be physical objects.

But doesn’t neuroscience show that there is a tight correlation between our thoughts and brain activity? It does indeed. So what? If you smudge the ink you’ve used to write out a sentence or muffle the sounds you make when you speak it, it may be difficult or impossible for the reader or listener to grasp its meaning. It does not follow that the meaning is reducible to the physical or chemical properties of the sentence. Similarly, the fact that brain damage will seriously impair a person’s capacity for thought does not entail that his thoughts are entirely explicable in terms of brain activity.

Aristotle and Aquinas, though they regarded the human intellect as immaterial, would not have been surprised in the least by the findings of modern neuroscience. Indeed, they would have been surprised had neuroscience not turned up the correlations it has. This will sound surprising if you take Descartes as your paradigm of a philosopher who affirms the immateriality of the human mind. But defending Descartes is exactly the reverse of what I have been doing. For it was Descartes who substituted the real, concrete human being -- a seamless unity of the physical and the mental, the bodily and the immaterial -- with a bizarre patchwork of abstractions of his own devising. Materialists have followed him ever since. Materialism is just a riff on Cartesianism, not its opposite. Tomorrow, I’ll explain exactly what I mean.

What Is at Stake?

What does it mean to be human? In what ways, if any, is our essential humanity tied to body and soul, mind and brain? This is not the stuff of mere curiosity. A host of pressing issues are at stake:

• Is there anything about humans that our mechanical creations, our innovations in Artificial Intelligence, will be unable to duplicate?
• What view of the human person helps us to find what we want to know about ourselves theologically — about sin, for example, as well as moral responsibility, repentance, and growth in grace?
• Am I free to do what I want? Given what we have learned about brain functioning, how might we understand the “free” in “free will”?
• What portrait of the human person is capable of casting a canopy of sacred worth over human beings, so that we have what is necessary for discourse concerning morality and for ethical practices?
• If humans, like sheep, can be cloned, will the resulting life form be a “person”?
• How should we understand “salvation”? Does salvation entail a denial of the world and embodied life, focusing instead on my “inner person” and on the life to come?
• How ought the church to be extending itself in mission? Mission to what? The spiritual or soulish needs of persons? Society-at-large? The cosmos?
• What happens when we die? What view(s) of the human person is consistent with Christian belief in life-after-death?

For many, and not least for many Christians, what makes a human genuinely human is the identification of the human person with his or her soul. From the second century on, theologians debated the origin of the soul: Are souls created by God ex nihilo at the moment of their infusion into the body? Are body and soul formed together? Are souls preexistent? Indeed, in the late-second century it was clear to many, as the Letter to Diognetus puts it, that “the soul dwells in the body, yet is not of the body” (1.27). Traditionally, systematic theology has discussed the uniqueness of humanity in two theological loci: human creation in the divine image and the human possession of a soul. Often these two are reduced to one, with the soul understood as the particular consequence of creation in God’s image.

For persons of faith — Christians included, but many others besides — the idea of a soul separable from the body is not only intuitive but necessary. We have regularly appealed to the soul as proof that humans are not mere animals, and so as a foundation for our views of the sacredness of human life. Moreover, Christians generally have derived from belief in the existence of the soul their affirmation of the human capacity to choose between good and ill. Further, the existence of a nonphysical soul, distinct and separable from the body, is typically regarded as the means by which human identity can cross over the bridge from this life to the next. Indeed, traditional Christian thought has tended to regard the body as frail and finite, the soul as immortal.

But it is the human possession of a “soul” that science now questions. When, as neurobiology and evolutionary psychology increasingly urge, the attributes and capacities traditionally allocated to the human soul are conditioned at point after point by biological processes, on what basis can belief in a soul be maintained? If science is generating “a radically new understanding of what it means to be human,”³ then those of us in the church must prepare ourselves for searching questions about the propriety of Scripture and traditional Christian thought in our talk about humanity, salvation, the end time, and more.

Before we engage too much in worried hand-wringing, however, we should ask whether our situation is so dire. Do these innovations in our understanding of personhood in fact call into question our deepest beliefs as Christians? Interdisciplinary study — with contributions from neuroscience, but also from biblical studies, theological studies, ethics, and philosophy (see “Further Reading,” below) — are demonstrating that emerging scientific portraits of the human person are neither as novel as we might imagine, nor as threatening to the essential tenets of Christian faith.

Biblical Contributions

In the context of current discussion on the nature of the human person, the Christian Scriptures have two primary contributions. First, taken as a whole, the biblical witness is fully congruent with a view of the person that affirms the human being as bio-psycho-spiritual unity. Neurobiological evidence and/or philosophical arguments favoring some form of monism are not at all hostile to the witness of Scripture. Second, we must recognize that the Old and New Testaments do not define the human person in essentialist but above all in relational terms. Put differently, the Bible’s witness to the nature of human life is at once naive and profound. It is naive not in the sense of gullibility or primitiveness, but because it has not worked out in what we may regard as a philosophically satisfying way the nature of embodied existence in life, death, and afterlife. It is profound in its presentation of the human person fundamentally in relational terms, and its assessment of the human being as genuinely human and alive only within the family of humans brought into being by Yahweh and in relation to the God who gives life-giving breath. This non-negotiable biblical insight is being recovered by some scientists today — e.g., by J. Polkinghorne and W.S. Brown, each of whom has urged that the notion of “soul” be recast in relational terms.⁴

We can press further. First, Scripture outlines a series of qualities of the human person that contrast sharply with the “modern self” derived from dualistic portraits. In his Sources of the Self, C. Taylor finds that, for modern folk, personal identity has come to be shaped by such assumptions as self-sufficiency, self-determination, and self-referentiality (“I am who I am”); that persons have an inner self, which is the authentic self; and that self-autonomy and self-legislation are basic to authentic personhood (Harvard University Press, 1989). Without majoring on the notion of a metaphysical entity of the “soul,” Taylor’s analysis nonetheless intimates how modern, personal identity has been cultivated in the garden of anthropological dualism.

In Scripture, however, we find such emphases as the following: the construction of the self as deeply embedded in social relationships and thus the importance of dependence/interdependence for human identity; a premium on the integrity of the community and thus the contribution of individuals to that integrity; the assumption that a person is one’s behavior; an emphasis on external authority — that is, the call to holiness is a call to a human vocation drawn from a vision of Yahweh’s “difference”; and the reality of dualism vis-à-vis good/evil, resident in and manifest both outside and inside a person. The line from a substance dualism that locates personal essence in the “soul” to this vision of personal identity is not easily drawn.

The point is that the construction of personal identity that pervades modernity is at odds with biblical anthropology at almost every turn, while the witness of Scripture and the findings of neuroscience are converging at significant points.

Second, negatively, we err when we imagine that it is the “soul” that distinguishes humanity from non-human creatures. Aristotle is closer to the biblical tradition in his view that the soul is that in virtue of which an organism is alive (On the Soul 2.1 §§412a-413a10). Given this conceptualization, there is no particular reason to limit the idea of “soul” to the human person. Within the Old Testament, “soul” (Hebrew: nepheš) refers to life and vitality — not life in general, but life as instantiated in human persons and animals. Nepheš is not a thing to have but a way to be. To speak of loving God with all of one’s “soul,” then, is to elevate the intensity of involvement of one’s whole being. Accordingly, the Common English Bible gets it right when it translates “the first and greatest commandment” in this way: “You must love the Lord your God with all your heart, with all your being, and with all your mind” (Matthew 22:37). Morever, in the creation accounts of Genesis 1-2, the Hebrew term used of human beings in 2:7, nepheš, is also used with reference to all sorts of wildlife, to everything “in which there is life (nepheš)” (1:30). This demonstrates incontrovertibly that “soul” (nepheš) is not, under this accounting, a unique characteristic of the human person. Accordingly, one might better translate Genesis 2:7 with reference to the divine gift of life: “the human being became a living person” — or, to quote again from the Common English Bible: “The human came to life.”

Third, thinking still of Genesis 2, it is instructive that the same texts that are silent on the infusion of a human soul into a dust-created body nevertheless distinguish by their use of the term nepheš between a being that has life and lifelessness. This speaks against any dualism that deprecates the body in favor of the soul and against any conceptualization of disembodied human existence in this life or the next. It also contravenes the widely held view that the quality of human life is vested in some thing or quality intrinsic to the individual person and that, in order to speak meaningfully of an afterlife, this “thing” must survive death. The soul does not distinguish human life as human or of particular value, but the graciousness of God does. Scripture situates the human family within the grand narrative of God’s doing; this narrative places a premium on human relatedness to God, humanity, and the cosmos because it is determined by God’s own character; and it is precisely within this narrative that the human creature draws both its value and its reason for being.

Hence, from a vantage point within the biblical narrative, avenues determined by autonomous individualism, interior psychic and/or mental processes, or the behavior of a vast assembly of nerve cells are mistaken, however well-worn they may have become. Although each of these accounts might appear to support a workable portrait of the human person and of human health, none of these carry us far in our concern to address our deepest human questions about what it means to be fully human.

What does it mean to be human? From a perspective within the biblical narrative, the way forward is marked by an account that rejects the necessity of a separate, metaphysical entity such as a soul to account for human capacities and distinctives; that underscores the material location of the human person in relation to the created order; that refuses to reduce personal identity to our neural equipment but rather emphasizes the personal contribution and relatedness of human beings to the human family and the cosmos; and thus that has as its primary point of beginning and orientation the human in a partnering relationship with God.

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

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

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

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

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

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

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

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

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

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

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

I am glad to have the opportunity to dialogue with Dr. John Hammett. In addition to our shared Christian faith and our shared lack of expertise in evolutionary science, we have in common one of our teaching and scholarly foci: the nature of human persons. Dr. Hammett approaches this topic as a trained theologian, whereas I approach it as a philosopher. However, on a topic such as this one, those disciplinary boundaries can get smudged a bit when the discussants approach the matter from the standpoint of a biblically-rooted Christian faith. Indeed the issue is of such importance and complexity that I would welcome continued conversation with Dr. Hammett beyond this initial exchange.

The Christian Scriptures teach that we human beings have been created in God’s image. What does that mean? I am in substantial agreement with Dr. Hammett on this question. While I think that bearing God’s image involves our having or having a potentiality for certain basic psychological capacities that we associate with the term “person”, it has to do even more profoundly with our specific capacity for relationship with God. Indeed, I would go further and say that it is not just our having this capacity that makes us divine ikons, it is also the fact that God has activated this capacity—He has given the precious gift of His self-disclosure to us. Further still, it has an eschatological dimension, based on the revealed promise of a future development and perfection of each of us, and so by implication, of human nature itself, by almighty God. We are in the process of becoming fully human: beyond a descriptive biological or even psychological notion of human nature lies a teleological one—not a telos of nature but of God's loving purposes for us. Despite our unequally born deficits—physical, cognitive, emotional, and moral/spiritual—we are destined for a fuller, supernatural realization of our common nature.

That we are in these ways God’s image bearers is a (wonderful!) teaching of our faith. The Scriptures also speak in various places of the human “soul.” The idea of the soul seems clearly connected to the idea that we are divine ikons. But here we should tread carefully. It is of course not unique to the Hebrew and Christian Scriptures to use some such singular term to refer to that which is most distinctively human and that by virtue of which we are able to survive the death and decay of our bodies. But it is one thing to use the term as a kind of placeholder for whatever it is about us that enables us to be, feel, and act in distinctively human ways in this life and to survive death into the next; it is another thing to link the term to a specific metaphysical account of the matter, such as might say whether the soul is a kind of thing or substance, what kind of thing it is, and exactly how “it” relates to the human “body.”

It is (and always has been) very common for Christians to invest the term “soul” as it used in Scripture with such a metaphysical account. As these fellow Christians understand it, when the Bible speaks of my soul, it is referring to an immaterial substance that is, in the final analysis, the thing that I am. I have my body (by interacting directly with it and only with it among physical objects), but I am my soul. Many will add that, after my death and prior to the resurrection of the dead, I will exist in a completely disembodied state—a naked soul, as it were.

However, I believe it is a mistake to interpret Scripture as teaching or implying any such metaphysical account of the underpinnings of our distinctively human personal attributes or our capacity for surviving death. Now, after reflecting on the matter, we might conclude that the only way these Scriptural teachings could be true is for such a metaphysical account to be true, as well—an account in which we are immaterial substances, entirely separate from our bodies. Indeed, many have thought hard about it and have drawn just such a conclusion, and it is not hard to see why they find it tempting to do so. But to do so is to make a disputable philosophical inference; it is not a teaching of the faith.

The general perspective of BioLogos, which I embrace, is that theorizing about the underlying nature of the soul is best done by trying to read God’s Two Books (His Word and His Works) in tandem. Both Books have a great deal to say about us, and, as common products of an infinitely wise and loving Creator, what they say must ultimately be in harmony. As with any attempt to understand something deep and wondrous in God’s Creation, we should proceed with humility and carefulness and be prepared to rethink familiar and received ideas.

Spelling it out just a bit, the common Christian understanding of what it is to have a soul involves the yoking of two radically different things, a functioning human (wholly material) body and an immaterial mental thing that is the direct bearer of psychological properties such as self-awareness, emotions, and thoughts, and is that which chooses in accordance with desires and purposes. In short, a complex biological machine and a pure subject/purposive agent which interface in the brain. I want to acknowledge that this is a very natural perspective to have, quite apart from Christian revelation (hence its popularity among humans generally). It is very natural because our psychological abilities seem, introspectively, to be plainly something more than mere resultants of impersonal physical particle interactions, however numerous and complex these are within the human brain.

We can design highly sophisticated computers that process complex bodies of information with extraordinary speed, but no computer is a subject, or has a point of view. As philosophers of mind like to say, there is nothing “it is like” to be a computer in the way that there is something “it is like” to be a conscious subject. Put another way, no mere computer is a conscious, experiencing subject, having a point of view from which it regards and interacts with its environment. Neither do computers make autonomous choices in the face of competing moral and self-interested motivations, and so on. It seems but a short step from this observation to the conclusion that human persons (and thinking/desiring/choosing things more generally) must be fundamentally different sorts of things: fundamentally distinct capacities must reside in fundamentally distinct kinds of substances (mental and spiritual substances as opposed to physical substances, however complex).

I have just described how matters appear from the ‘first-person perspective’ of conscious experience and self-awareness. Let me be clear that I take such evidence very seriously: I know my own conscious thoughts and experiences better than I know any scientific theory,—even a very well-attested one—as all of our theories are at bottom built on information we derive from our experiences. So awareness of the distinctive character of conscious experience is part of what is given to us in the Book of God’s Works, since we are a part of that Book.

But alongside that ‘first-person’ data, we have had an explosion of relevant information coming from the ‘third-person’ perspective of the natural sciences, specifically evolutionary and developmental biology and cognitive neuroscience. This information, while still incomplete and only imperfectly understood, sheds light on the deep natural history of humans and present-day animals; the processes by which individual organisms of any species develop from inception to maturity; function-specific neural structures and processes that sustain and help regulate the unfolding first-person perspective of conscious agents; and finally, observed correlations between increasing complexity of neural structures and increased psychological complexity. This last correlation between structural and cognitive complexity is evident both when examining individuals as they develop, and when making comparisons across sentient species.

I suggest that this third-personal scientific information does not comport well with the two-substance or dualist metaphysical account of human persons. The fundamental problem is that our sciences point to continuous processes of increasing complexity, but the two-substance account requires the supposition of abrupt discontinuity. The “coming to be” at a particular point in time of a new substance with a suite of novel psychological capacities would seem to be a highly discontinuous development, both in large-scale bio-geological time and within the development of individual organisms.

Since souls as purely immaterial things would lack parts, we cannot make sense of the accumulation or diminishment of capacities by proposing increased or decreased structural complexity within the bearer of such capacities. And it just seems implausible to suppose that all the necessary basic capacities for, say, calculus problem-solving are there in the soul from the beginning, awaiting only physical maturation in the body in order to become activated, but still not directly dependent on that maturation. It seems rather that psychological capacities arise and develop in tandem with the development of the brain and nervous system.

Of course, it is possible for the soul-body dualist to retrench: we might offload to the brain ‘side’ of the divide some of the psychological functioning that, prior to the advent of neuroscience, we might have mistakenly thought belonged to the soul. But that tack risks (as neuroscience progresses) reducing the soul to a simple, immaterial object that is radically incomplete, merely a “bearer of consciousness” that enables personal identity over time and through death.

Despite the fact that such future retrenchment would seem to be required, this kind of dualism remains tempting for the Christian thinker. Why? The obvious answer is that it can seem to be the only way to accommodate our specifically Christian data that human beings are not mere machines: our thoughts, emotions, goals, and intentions are deep, not superficial features of ourselves; they confer a dignity upon us that makes us suitable bearers of the divine image such that human beings, after our skin has been destroyed, will yet see God. (Job 19:26). But is it true that the coherence of Christian theology requires this account? And if coherence of Christian theology does not require this account, which account might be the best one?

Tomorrow, in Part 2, I will address this question.

Author's Note

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

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

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

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

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

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

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

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

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

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.
