On Weird Theories



AUTHOR: Allen MacNeill

COMMENTARY: That's up to you...

"... say what you like about the tenets of National Socialism, Dude, at least it's an ethos."
- Walter Sobchak, The Big Lebowski (1998)

I had a next-door neighbor who worked for an aerospace company. One summer afternoon we were sitting beside his barbeque in his back yard, having one of those stream-of-consciousness conversations that often accompanies the guzzling of a six pack or two (his brand was Pabst Blue Ribbon™). I don't remember how the subject came up, but somewhere along the line I must have done what my wife calls "hitting the core-dump button." And he did; for the next couple of hours I listened in semi-horrified fascination as he expounded on his "theory" of reality. Basically, it was a weird variant on the "eagle and snake" mythology of the Aztecs, except that in his own weird theory the snake was the major icon. He went on and on about how the world (and time and everything else) was, at some much deeper level of reality, a snake. Ouroboros and the Midgard Serpent and Satan in the Garden of Eden and Freud's phallic symbols and the Caduceus and on and on and on...it was all tied together in a huge, complicated, and ultimately deranged web of relationships. It clearly was very meaningful to him; at times he seemed on the verge of tears. He showed me a medal of the Aztec eagle-and-snake image, which he wore around his neck at all times (even to bed and in the shower). He told me how it got him through some bad times in Vietnam, and later when he almost broke up with his wife. The emotional connections were so intense that he was shaking at times, and there was a catch in his voice.

This wasn't the first (or the last) time something like this has happened to me. Several times – on the bus or in the bus terminal, on a long car trip with a friend, at the airport, over lunch, at a picnic for work or a fraternal organization – someone hears or thinks of the word or phrase that "hits the core-dump button" and out it all comes. You sit there, in awe and trepidation, while the core-dumper gives you their entire "weird theory" of reality, all in one huge, steaming, highly charged, stream-of-consciousness pile. Sometimes it's clear that they have never articulated this before to anyone. Other times it's clear that they've been working on this particular monolog, maybe for years, and have already "gifted" others with a very similar version. Every time it's always intensely emotional for them, as the whole weird mess unspools and they search your face for some sign of recognition, of empathy, of understanding.

And, with me at least, they don't get that. I listen politely, trying not to look perplexed or horrified, waiting for the whole thing to come tumbling out, and hoping for something to then divert us – the burgers starting to burn or the bus arriving or the teller asking for my driver's license. I nod sometimes, and grunt in what I hope is a non-judgmental way, and quietly wish for someone or something to intervene before the core-dumper realizes that, not only to I not empathize, I think they're nuts.

Because they are, at some very deep level. Almost all of us are; completely whacked. What we almost all have, buried deep in our psyche, is what I call a "weird theory of reality," in which we believe passionately, and into which we shoehorn almost every perception we have about reality. Furthermore, it's clear to me that people have always had such "weird theories" about reality. Today it's alien abductions or UFOs, astral projections, mental telepathy, ESP, clairvoyance, spirit photography, telekinetic movement, full trance mediums, the Loch Ness monster and the theory of Atlantis. Yesterday it was angels and demons, fairies, gnomes, trolls, heaven and Hell, transubstantiation, faith healing, walking on water, flying, and speaking in tongues. Tomorrow...well, I can't say for sure, but I am sure it will be something weird.

What makes modern "weird theories" different from those of the past is that today everyone has their own "weird theory". When people lived in small agricultural villages or even smaller hunter-gatherer groups, people had weird theories, but these were pretty similar within those groups. Heresy was difficult, if not virtually unthinkable, because everyone in a particular group was in constant verbal and emotional contact with virtually everyone else, and there was a strong incentive to conform to group norms of belief.

This pattern persisted into historic times with the establishment and enforcement of "state religions" - that is, weird theories of reality that had the force of political coercion behind them. People may have had personally idiosyncratic versions of the group's weird theory, but they generally kept these to themselves. These "group weird theories" (GWT) were the mythologies that held such groups together, that gave them a sense of shared experience and shared purpose, and that facilitated group coordination. This was often a good thing, but sometimes a bad thing: it made possible group coordination in agriculture and response to natural disasters, but also facilitated warfare and small-scale genocide.

What characterizes us now is that our weird theories are almost entirely idiosyncratic, especially in the First World. We have largely given up the large-scale group mythologies and religions of the past, and replaced them with what could be called "personal mythologies and religions". That Protestantism is the most influential religion in America today is precisely because it isn't a single religion: it's thousands, even millions of little idiosyncratic religions, with some shared similarities. Schism, right down to the individual level (and even within individuals at different times in our lives) is the norm, and so our weird theories are not only weird, they're mutually incomprehensible.

So, are the various sciences also "weird theories"? Anyone acquainted with the current state of quantum physics would almost certainly agree, as would most evolutionary biologists. But, it's not really the same, because although there are many weird theories in science, there is also an underlying agreement that is deeply "unweird" – the idea that empirical verification and logical inference is the basis for all of our weird theories.

Ultimately, the difference between non-scientific and scientific "weird theories" is that eventually the latter become generally accepted by the scientific community in the same way that the grand overarching religious weird theories of past centuries were. Yes, there are still schisms in science (think of the controversies surrounding punctuated equilibrium versus phyletic gradualism), but in the long run these schisms tend to heal themselves. Thomas Kuhn described this process well, but he also asserted (and most scientists would agree) that eventually the various scientific communities agree on their dominant paradigms. Science, in other words, tends to become more unified over time, as deep connections between the various weird theories stitch them together into "grand unified theories".

By contrast, the non-scientific "weird theories" schism and schism and schism, until they become the incomprehensible idiosyncratic messes that one taps into when one hits the "core-dump button". Indeed, one of my personal weird theories is that this is a good way to distinguish between useful (i.e. "true") and pointless (i.e. "false") weird theories: the former tend to unify your ideas with those of the other members of your community, whereas the latter tend to separate us to the point of mutual incomprehensibility.

Hence, the quote from The Big Lebowski: say what you say what you like about the tenets of (insert scientific discipline here), Dude, at least it's an ethos.

The "Intelligent Design" Movement on College and University Campuses is Dead


AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

On 22 December 2005, I posted a critical analysis of a press release on the Kitzmiller v. Dover decision, written by Dr. William Dembski, one of the founders of the "intelligent design" movement (Dr. Dembski's press release is apparently no longer available online). My analysis of Dembski's press release was hosted by Ed Brayton at his blog, Dispatches from the Culture Wars (you can find it here). In my analysis, I noted that Dr. Dembski had made a series of statements that were so divergent from the actual facts that they could be interpreted as symptoms of delusional thinking on the part of Dr. Dembski, if not deliberate falsehoods.

Here's the claim by Dr. Dembski that I would like to re-examine in this post:
Three years ago, there was one Intelligent Design and Evolution Awareness (IDEA) Center at the University of California-San Diego. Now there are thirty such centers at American colleges and universities, including UC Berkeley and Cornell. These centers are fiercely pro-ID. [emphasis added]

Dr. Dembski strongly implied in his press release that these IDEA Centers were essentially research centers, such as those commonly found at college and university campuses.

Well, they aren't...or, rather, weren't. They weren't "research centers" or anything like it. They were clubs, similar to the kinds of student-centered special interest clubs that abound on most college and university campuses. Such clubs have several characteristics in common:
1) they are founded, supported, and run by students (sometimes with support from affiliated national organizations),

2) they often have to have permission from the administration to use classrooms or other facilities for meetings, and

3) they sometimes receive funding from students, derived from student activities fees.

To do these things, campus organizations typically have to show that they have no political or religious requirements or ties, as this could jeopardize the academic institution's not-for-profit educational status. This was a problem for IDEA Clubs, for several reasons:
1) they were usually founded, supported, and run by students who received encouragement and training to do so from the national IDEA Center, a spinoff of the Discovery Institute in Seattle, Washington, the political "nerve center" of the "intelligent design movement";

2) the IDEA Clubs often met in campus classrooms or other facilities; and

3) some IDEA clubs did in fact receive funding derived from student activities fees.

This was problematic for two simple reasons:

1) the Discovery Institute receives much of its funding from religious organizations, especially those supported by Christian "reconstructionist" Howard Ahmanson (that this is the case can be easily verified by reading the so-called "wedge document", formulated by the Discovery Institute as a fund-raising tool);

2) the IDEA Center required that the founders and officers of the IDEA Clubs they helped organize and support be Christians.

This was the case for the IDEA Club chapter founded at Cornell University, with whom I had several debates and public meetings. The requirement that the Cornell IDEA Club's officers be Christians was withheld from its membership by its founders until it was made public by their opponents. This caused dissension within the club and eventually led to the modification of this policy by the national IDEA Center administration.

And so, to the purpose for this post: it appears from all indications that the IDEA Club "movement" (and, by extension, the "intelligent design movement" as a whole) is dead. You can verify this by going to the website of the national IDEA Center and clicking through the various links located there. I did that this morning, and found it very enlightening. To save you time, here is what I found (the links are listed first, followed by what they lead to):

Upcoming Events

And there you have it: not one of the IDEA Clubs affiliated with an academic institution is still functioning. Indeed, only one of the clubs listed has even updated its website during the past year (the Tri-Cities IDEA Club).

UPDATE (01/04/09): The Tri-Cities IDEA Club website has now descended into "Under Construction/Placeholder" Hell, and so all of the current links to IDEA Clubs at the national IDEA Club website are currently non-functional.

Furthermore, a quick statistical analysis is also illuminating:
1) there are 39 IDEA Clubs listed, not 35 (as stated at the IDEA Club main website);

2) of the 39 listed IDEA Clubs, eight (21%) are located at high schools or community colleges;

3) four (17%) are located at religious institutions;

4) nine (23%) simply do not exist (i.e. have 404: File Not Found at their link); and

5) 18 (46%) have links that simply redirect to either a national IDEA Center press release or main website homepage.

These are the "intelligent design research centers" about which Dr. Dembski spoke so glowingly in his analysis of the effects of the Kitzmiller v. Dover Area School Board decision.

What can one conclude from this analysis? I conclude five things:
1) that the national IDEA Club website is essentially what is known online as a "shell site" (that is, a place-holder with no real content);

2) that the "movement" represented by the IDEA Club organization peaked in late 2005 or early 2006 (around the time of the Kitzmiller v. Dover trial);

3) since then (i.e. since Judge Jones issued his now-famous decision) it has died almost everywhere;

4) the majority of the output of the "intelligent design movement" consisted of press releases (and produced no empirical science of any kind); and

5) my conclusion in my critical review of Dr. Dembski's analysis of the Kitzmiller v. Dover Area School Board decision was essentially correct: he was (and probably still is) either delusional or a bald-faced liar.

So, why did I illustrate this post with a picture of a dodo? Because, like the "intelligent design" movement, the dodo was notorious for its stupidity and that fact that it is extinct.

UPDATE (09/01/09): All of the current links to IDEA Clubs at the national IDEA Club website are currently non-functional; if this keeps up, they may fossilize.

As always, comments, criticisms, and suggestions are warmly welcomed!

It's Darwin-Malthus Day!


AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

Most readers of this blog are aware that next year is the Darwin Bicentennial. It's the 200th anniversary of the birth of Charles Darwin and the 150th anniversary of the publication of the Origin of Species. Regular readers also know that this celebration really started this past July 1st, which marked the 150th anniversary of the joint presentation of Darwin and Wallace's theory of evolution by natural selection at the summer meeting of the Linnean Society in London.

However, what many people don't know is that today is also a very significant anniversary of a crucial development in Darwin's theory of evolution by natural selection. On this day in 1838, Darwin
"...happened to read for amusement 'Malthus on Population,' and being well prepared to appreciate the struggle for existence which everywhere goes on from long-continued observation of the habits of animals and plants, it at once struck [him] that under these circumstances favourable variations would tend to be preserved, and unfavourable ones to be destroyed. The result of this would be the formation of new species." [Darwin's Autobiography, page 83]

According to his autobiography, Darwin read Malthus' famous essay in the evening, and the idea of natural selection sprang fully formed into his mind: "Here then I had at last got a theory by which to work...", and indeed he had. But Darwin was an extraordinarily cautious man, always seeking to avoid controversy and notoriety. In his autobiography he says,
"...I was so anxious to avoid prejudice, that I determined not for some time to write even the briefest sketch of it."

And indeed, he did not. It wasn't until 1842 that he felt confident enough about his theory to set it down on paper, and it wasn't until two years later that he had this original "pencil sketch of 1842" copied out and put into a form that he felt confidant enough about to share with his closest friends. It was this "Essay of 1844", along with a letter to the American botanist, Asa Gray, that were read at the July, 1858 meeting of the Linnean Society along with Alfred Russell Wallace's unpublished manuscript "On the Tendency of Varieties to Depart Indefinitely from the Original Type", which marks the beginning of evolutionary theory's annus mirabilis.

So, the "evolution revolution" really began on a rainy evening in late September in 1838, when Charles Darwin read Malthus "for amusement"...

...and it's also my birthday.

Announcing a New Blog: Evolutionary Psychology


AUTHOR: Allen MacNeill

SOURCE: Evolutionary Psychology

COMMENTARY: That's up to you...

As if I didn't already have enough to do, I have started a new blog. Entitled "Evolutionary Psychology", it is intended as a companion blog to The Evolution List. I have felt for quite a while that there are no really informative blogs on the subject of the evolution of human behavior, and so decided this morning to do one myself.

I have been learning about and doing research in evolutionary psychology for over thirty years (that is, since it used to be called "sociobiology"). Several years ago, I prepared a series of lectures on the subject, complete with images, links, and references, which I intended to use as the basis for a course on the subject. These "lectures" will therefore serve as the core of the new Evolutionary Psychology blog.

The first post on the new blog (The Capacity for Religious Experience is an Evolutionary Adaptation for Warfare) is a repost of one of the most popular posts here at The Evolution List. I have reposted it again, partly to commemorate the 63rd anniversary of the atomic bombing of Hiroshima, and partly to give the new blog a good kickoff. I hope you will take a look, and if you like it, please spread the news.

As always, comments, criticisms, and suggestions are warmly welcomed!

The Dover “Monkey Trial”

In 2004 the school board in Dover, Pennsylvania voted to require that the following statement be read to students taking biology in the Dover Area School District:

The Pennsylvania Academic Standards require students to learn about Darwin’s Theory of Evolution and eventually to take a standardized test of which evolution is a part.

Because Darwin’s Theory is a theory, it continues to be tested as new evidence is discovered. The theory is not a fact. Gaps in the theory exist for which there is no evidence. A theory is defined as a well-tested explanation that unifies a broad range of observations.

Intelligent Design is an explanation of the origin of life that differs from Darwin’s view. The reference book Of Pandas and People is available in the library along with other resources for students who might be interested in gaining an understanding of what Intelligent Design actually involves.

With respect to any theory, students are encouraged to keep an open mind. The school leaves the discussion of the Origins of Life to individual students and their families. As a Standards-driven district, class instruction focuses upon preparing students to achieve proficiency on Standards-based assessments.


Thus began the most recent battle in what historian and philosopher Michael Ruse has called “the evolution wars”. This particular battle climaxed in a civil case brought in the United States District Court for the Middle District of Pennsylvania, Judge John E. Jones, III, presiding, begun in September of 2005 and ending with Judge Jones’ decision in the case, issued on December 20, 2005. Entitled “Kitzmiller, et al. v. Dover School District, et al.”, the trial is often referred to as the “Dover Monkey Trial”, in reference to the 1925 trial of John T. Scopes in Dayton, Tennesee, as chronicled by H. L. Mencken in the Baltimore Sun and dramatized in the award-winning play, movie, and television drama, Inherit the Wind.

The title of Jerome Lawrence and Robert Lee’s play about the Scopes “monkey trial” comes from the King James version of the Bible:

He that troubleth his own house shall inherit the wind
and the fool shall be servant to the wise of heart.
- Proverbs 11:29


In many ways, that quotation would be even more fitting to the outcome of the Kitzmiller v. Dover trail. As chronicled in two new books and a new NOVA video, the Dover trial not only set a new standard for the teaching of evolution and intelligent design in the public schools, it also set neighbor against neighbor in a little town in Pennsylvania where the most common source of conflict was local sports rivalries. As one of the participants in the trial, Casey Brown (a witness for the plaintiffs) commented,
“I was afraid Dover would never be the same [after the trial], and I was right”.


The title of Edward Humes’ book about the Dover trial, Monkey Girl, comes from a taunt that was hurled at the daughter of the chief plaintiff in the trial, Tammy Kitzmiller. Humes analyzes the Dover trail from both an historical and legal perspective, and provides many vignettes that illustrate the truth of Casey Brown’s concern. The Dover trial divided the citizens of Dover along political and religious lines in much the same way that the Scopes “monkey trial” divided the nation in 1925.

Humes’ book not only follows the legal arguments in the case, it also chronicles the personal and social costs of the trial, to members of both sides of the dispute. In particular, he analyzes the political and religious views of the members of the school board who voted for the reading of the statement recounted above, and the reactions by the science faculty at the Dover schools to the requirement that it be read to their classes.

It becomes clear on reading Humes’ account that there was much more at stake in this dispute than the wording of what appears to be a fairly harmless statement to be read to biology students. Underlying this action was (and is) an ongoing dispute about the moral effects of science education in general, and the teaching of evolutionary theory in particular. One side – represented in the Dover case by the members of the school board who voted for the reading of the statement – believed that the teaching of evolution is causally linked to what they perceive as the “rising tide of atheism and social disintegration in America”.

The other side – represented by the plaintiffs and their supporters among the Dover science faculty – believed that the intrusion of “intelligent design” into the public school curriculum was not only detrimental to the understanding of science, it was also part of a covert program of religious indoctrination and intolerance. It was these views, and not the simple wording of the statement to be read to students, that generated the heat in the courtroom, and the bitter controversy that divided the Dover community during and after the trial.

Lauri Lebo was a newspaper reporter covering the Dover trial, and also a long-time resident of the Dover area. She knew most of the participants on both sides of the dispute in the trial personally, and experienced first hand what some of the people on both sides of the issue suffered as a result of the political process that led up to the vote approving the reading of the statement, and the subsequent trial. Her account in The Devil in Dover is less focused on the legal issues, and more concerned with the effects of the trial on the personal lives of the people involved. It becomes clear from her account that there were no “winners” in this dispute, at least not insofar as individuals on one side or the other emerged from the trial unscathed. In her opinion (and in Humes’), science was the winner in the Dover trial, but at a significant cost to the participants on both sides of the dispute.

The NOVA video, Judgement Day: Intelligent Design on Trial, focuses primarily on the political and scientific issues in play in the Dover trial. As is the case in most Federal courts, photography and video recording of the trial were not allowed. Therefore, the producers of Judgement Day used dramatizations of key testimony in the trial to illustrate not only the content of the testimony, but to also give a flavor of how the testimony was presented and received.

Of these dramatizations, perhaps the most effective is that of intelligent design theorist Michael Behe, a professor of biochemistry at Lehigh University. Behe’s own evaluation of his testimony immediately after he presented it was that it would decisively carry the day for intelligent design, not only in the Dover case, but in American society in general. However, it is clear while watching the dramatization that exactly the opposite was the case: Behe’s testimony was devastating, not only to his own credibility as an expert witness, but also to the reputation of intelligent design as a science.

Taken together, these two books and video present both the essential facts and the personal and social impact of the Dover “monkey trial”. In my opinion, they are probably as close to an unbiased account as has appeared in the popular press since Judge Jones issued his historic decision in December, 2005. Readers who are interested in the legal details can read Judge Jones’ 138 page decision online here and consult the transcripts of the trial, available online here. Readers who are interested in how such a trial affects the participants would do well to read Humes’ and Lebo’s accounts, both of which are sympathetic to participants on both sides of the controversy.

There is one very important difference between the outcome of the 1925 Scopes “monkey trial” and the 2005 Kitzmiller v. Dover “intelligent design” trial: in 1925, John T. Scopes was convicted of having violated the Butler Act, which made the teaching of evolution in the public schools of Tennessee illegal. In 2005, the Dover Area School Board’s requirement that the statement at the beginning of this review be read was ruled unconstitutional, along with any inclusion of “intelligent design theory” in biology classes in the public schools of the Middle District of the Federal Circuit Court of Pennsylvania.

This difference marks a tectonic shift in the legal status of evolutionary theory versus creationism in the United States. What the two books and the video reviewed here also illustrate is how such shifts also involve personal and social costs (not to mention the huge monetary cost of pursing such complex legal cases) in the communities in which such court cases are tried. If history is any guide, the Dover trial will not be the last battle in the “evolution wars”. However, it does mark the “high tide” to date of science versus religion in American public education.

Judge Jones’ decision should be required reading for anyone concerned about science education in America. The NOVA video, Judgement Day, provides an excellent dramatization of the core of the legal dispute in the Dover case. Humes’ and Lebo’s books should be read by anyone concerned about the effects of injecting religion into science classes, both on the students, the teachers, and the communities in which all of them live. I recommend them all with the highest possible praise.

As always, comments, criticisms, and suggestions are warmly welcomed!

Phillip Johnson & "Theistic Realism"


AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...


Phillip Johnson, one of the founders of the intelligent design movement, has proposed an alternative form of reasoning to that used by modern scientists. He refers to his form of reasoning as "theistic realism", while the alternative could be called "empirical naturalism". In this blog post, I intend to contrast these two forms of reasoning, to determine what assumptions one must hold to apply them, and what consequences flow from adopting one or the other position, which I freely admit at the outset are essentially metaphysical (i.e. not scientific) positions.

According to Charles Darwin, Ernst Mayr (and most other evolutionary biologists), evolution has two stages:
• the origin of variations via various mechanisms
• the origin of adaptations via natural selection

Johnson's critique of evolution centers on the origin and patterns of variation, since he has repeatedly granted in various venues that natural selection occurs. However, according to Johnson, "God" (i.e. the supernatural entity/force behind "theistic realism") causes and/or guides the generation of variations, leaving natural selection as a mere "stabilizing force" that only maintains adaptations by weeding out unfit individuals. In this sense, Johnson's version of "natural selection" is virtually indistinguishable from that proposed in 1835-37 by Edward Blyth.

There are two fundamental problems with Johnson's position, one theological and one metaphysical:

• First, the idea that stabilizing selection maintains God-created variations is essentially a form of "statistical norming", and therefore violates the Judeo-Christian (and presumably, "theistically realistic") principle of "sanctity of the individual". If "not a sparrow falls, but that [God is] mindful of it", then God doesn't (indeed, cannot) treat individuals (including, presumably, individual humans) as instrumental entities (i.e. as means, rather than as ends) by weeding them out if they depart too much from the statistical norm of His created types. But, if God does pay attention and therefore intervenes on behalf of any and all individuals, then stabilizing selection doesn't really exist, and we are back to a theory of "theistic evolution" in which God directly intervenes in nature, controlling and guiding (i.e. determining) absolutely everything that happens at all times and in all places.

• Second, if Johnson grants that God directly intervenes only in the generation of variations (and lets stabilizing selection maintain the particular variations He specifies), there are still two alternatives:

- That God creates a multiplicity of variations, and then lets natural selection operate to choose which ones will become adaptations; or

- That God determines which variations will be adaptive at the instant of their creation, thereby rendering natural selection (and all naturalistic mechanisms of variation) superfluous.

In the first case, God not only commits the sin of "statistical norming" (as described above), the process by which He does so would result in a pattern of evolutionary change that would be virtually indistinguishable from purely naturalistic evolution by natural selection, which does not require God to intervene at all. He would, in other words, render Himself and His actions completely pointless and invisible.

But in the second case, the apparent stabilizing selection described earlier is illusory, since all created individuals would be ipso facto adaptive. Indeed, unless God deliberately intends to create maladaptive individuals that depart significantly from the adaptive norm (and which therefore would be eliminated by selection), there should be virtually no maladaptive individuals at all, which should be easily verifiable by empirical analysis.

Either Johnson must grant that stabilizing selection does, in fact, operate (and God is therefore not mindful of individuals, but only of types), or he must grant that it does not. In the second case, natural selection doesn't really happen at all, at any level, and God must therefore intervene directly in the survival and reproduction of every living organism that has ever existed, exists, or ever will exist. Furthermore, God does this despite the fact that only one type of organism, namely humans, has any choice about its behavior, about its living or dying (as far as we can tell).

To sum up, either:

• God (or the “Intelligent Designer”) intervenes directly in evolution via stabilizing selection, thereby destroying uncountable trillions of His creations (all of them innocent except humans, and even some of them, too) in order to "stabilize" His specified adaptations, or

• God (or the “Intelligent Designer”) doesn't intervene via stabilizing selection, in which case He's either irrelevant (i.e. natural selection "just happens") or He completely determines absolutely every event that occurs throughout all time and space, in which case "free will" (and therefore sin) is an illusion.

Furthermore, since Johnson grants that natural selection really does occur, but only as stabilizing selection, this limits God's intervention in the evolutionary process to the instant of the creation of variations. Under such conditions, the circumstances following this instant are empirically indistinguishable from pure naturalistic processes, regardless of whether God "specifies" such variations. Either that, or such variation is essentially random (and therefore "Godless" and “unspecified”).

But this position puts Johnson inescapably in the position of arguing once again for a "God of the gaps" position, since the only intervention God is capable of under such conditions is into the generation of variations; what happens afterwards is essentially "Godless". This is a "God of the gaps" position because there are only two alternative scenarios:

• A mechanism that produces variations that does not rely upon supernatural intervention will eventually be discovered and applied to the entire fossil and genetic record, the "gap" will be closed, and God (like the Baker) will "softly and silently vanish away"; or

• No matter when one inquires, a mechanism that unambiguously does not rely upon supernatural intervention will not yet have been (and indeed, cannot ever be) discovered.

It would seem like the second situation would validate Johnson's position. However, the second situation involves a fundamental (i.e. metaphysical) problem: the only absolutely validating outcome for the second alternative is that every possible mechanical (i.e. "Godless") explanation for the origin of variations must have been tested and falsified. This is a metaphysical impossibility, as the empirical method relies on induction, and no amount of positive evidence for Johnson's hypothesis (i.e. negative evidence for a "Godless" origin of variations) is enough to absolutely validate it (unless Johnson wishes to declare himself a logical positivist, which seems highly unlikely).

Given the foregoing, it appears that Johnson's assertion that God guides the origin of variations directly violates Popper's falsifiability criterion (just as Johnson claims evolutionary theory does). This is because, no matter how fine a level of discrimination one specifies for ruling out supernatural intervention in the origin of variations, Johnson can claim that God's intervention lies somewhere "deeper" (even if we someday get down to the level of sub-subatomic particles).

But, at some arbitrarily fine level of discrimination, either God's intervention will "jump out" of the statistical analysis (i.e. it will violate accepted principles of statistical reliability) or it won't. If it doesn't, the hypothesis of God's direct intervention in the origin of variations will have once again become unnecessary, and by the standard of parsimony (i.e. "Occam's razor"), if a causal factor is unnecessary, it isn't included in a scientific (i.e. empirically grounded) explanation of a phenomenon.

When one examines Johnson's metaphysical positions on these subjects, it is clear that he doesn't give a damn about empirical validation or falsifiability or statistical reliability or anything else that could conceivably be called "scientific". For example, in Defeating Darwinism by Opening Minds [1], Johnson states quite unequivocally:

"Truth (with a capital T) is truth as God knows it. When God is no longer in the picture there can be no Truth, only conflicting human opinions. (There also can be no sin, and consciousness of sin is that built-in moral compass [pro-Darwinian philosophers] reject...as illusory.)" [Defeating Darwinism by Opening Minds, page 89]


In my opinion, no more succinct a statement of anti-scientific thinking could be imagined. Johnson asserts that the only two alternatives are
(1) God-given Truth and
(2) conflicting human opinions.
Where, in either of these, is empirical verification? Is "God-given Truth" amenable to empirical verification? If Johnson thinks so, he flies in the face of centuries of both scientific and theological metaphysics, which has consistently concluded exactly the opposite. But what about the alternative: is Johnson asserting that all scientific principles, such as the law of gravity, are "human opinions"? This was the position taken by the author of the "Sokol Hoax", which of course was shown to be both a hoax and an indirect validation of the assumption that physical laws are not subject to human opinions. Ergo, if Phillip Johnson were of the opinion that the law of gravity does not apply to him, could he thereby escape its operation? Don't be ridiculous...

Johnson argues that we should, as scientists, conflate two totally incommensurate forms of "knowing":

Deontological Absolutism - a universe in which God's direct intervention in events occurring in the real world is self-evident and does not require empirical verification (in fact, to attempt such verification would qualify as blasphemy), or

Scientific Empiricism - a universe in which the assumption that God intervenes in any event that occurs in the phenomenal/physical universe is unnecessary, and therefore irrelevant to such an explanation.

That's what all this really comes down to: Johnson's "theistic realism" is semantically reducible to "its True because I say so, and I say so because I believe that God says so, too", since no amount of empirical evidence can either validate (or invalidate) his position. The only "proof" he provides (or requires) for his position is his assertion of it. Interesting, perhaps, as an exercise in theological metaphysics (not to mention hubris), but not, by any stretch of the imagination, science.

Day One of the Evolution Revolution



AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

I have mentioned several times in other posts that 2008 is the bicentennial of the birth of Charles Darwin and the sesquicentennial of the publication of the Origin of Species. Hundreds of scientific and cultural organizations are gearing up to celebrate Darwin's birthday on February 12th, proclaiming it the kickoff for the "Darwin bicentennial year".

However, in a very real sense, today is the first day of that centennial celebration. On the first of July 1858 two papers and two letters were read to the members of the Linnean Society in London. One of the papers, entitled "On the Tendency for Varieties to Depart Indefinitely from the Original Type", was written by Alfred Russell Wallace. The other paper and the two letters were written by Charles Darwin, and outlined his theory of evolution by natural selection.

The paper by Wallace had been sent to Darwin, with a request by Wallace that if it were of sufficient merit, would he please forward to the society for publication? Darwin was stunned; he had been working on the very same idea for almost twenty years. Here is what he wrote on 18 June 1858 to his friend, the geologist Charles Lyell, following his receipt of Wallace's paper:

My dear Lyell

Some year or so ago, you recommended me to read a paper by Wallace in the Annals [a natural history journal], which had interested you & as I was writing to him, I knew this would please him much, so I told him. He has to day sent me the enclosed [manuscript] & asked me to forward it to you. It seems to me well worth reading. Your words have come true with a vengeance that I shd be forestalled. You said this when I explained to you here very briefly my views of “Natural Selection” depending on the Struggle for existence.—I never saw a more striking coincidence. if Wallace had my M.S. sketch written out in 1842 he could not have made a better short abstract! Even his terms now stand as Heads of my Chapters.

Please return me the M.S. which he does not say he wishes me to publish; but I shall of course at once write & offer to send to any Journal. So all my originality, whatever it may amount to, will be smashed. Though my Book, if it will ever have any value, will not be deteriorated; as all the labour consists in the application of the theory.

I hope you will approve of Wallace’s sketch, that I may tell him what you say.

My dear Lyell
Yours most truly

C. Darwin


Knowing how long Darwin had labored on his theory, Lyell and botanist Joseph Hooker prevailed on Darwin to allow them to read his unpublished essay on natural selection (written in 1844) and two letters on the same subject from Darwin to Hooker and to the American botanist, Asa Gray, along with Wallace's paper at the July meeting of the Linnean Society. Neither Darwin nor Wallace attended the meeting (Darwin was at his home at Down, in Kent, mourning the death of his son, Charles, who had died three days earlier; Wallace was still in the Maylay archipelago), and the joint reading raised hardly a ripple of comment.

Despite their lack of notoriety at first, these papers and letters were the first public presentation of the theory that would fundamentally and radically change the way we view ourselves and the natural world around us.

Serial Endosymbiosis and Intelligent Design



AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

It's very gratifying to see Lynn Margulis finally getting the recognition that she deserves. As the most effective exponent of the serial endosymbiosis theory (SET) for the origin of eukaryotes, Lynn's work provides an excellent example of how ID should (but currently doesn't) proceed. During the late 1960s, Lynn published a series of revolutionary papers on the evolution of eukaryotic cells, culminating in her landmark book Symbiosis and Cell Evolution, in which she carefully laid out the empirical evidence supporting the theory that mitochondria, choloroplasts, and undulapodia (eukaryotic cilia and flagella) were once free living bacteria (purple sulfur bacteria, cyanobacteria, and spirochaetes, respectively).

Her theory was greeted with contempt and scorn by almost all evolutionary biologists (sound familiar?), who believed at the time that all eukaryotic cellular organelles evolved by gradual elaboration of invaginations of the plasma membrane. But Lynn didn't give up, or continue to simply restate her original theory (sound familiar?). Instead, she continued to do extensive field and laboratory research, publishing hundreds of papers and dozens of books in which she presented the accumulating empirical evidence supporting her theory. With time, other researchers (encouraged by the success of her field and lab research) began to test her hypotheses themselves, and discovered yet more empirical evidence supporting her theory.

And so today, Lynn Margulis's SET has become the dominant theory explaining not only the origin of eukaryotes, but also the origin of evolutionary novelty at dozens of different levels in biology (see her book, Acquiring Genomes for a comprehensive review). So well accepted has her work become by evolutionary biologists that finally, after almost four decades, creationists and ID supporters have begun to attack her theories. As she said at our Darwin Day celebration at Cornell this past February, no greater affirmation of one's "having arrived" as a major theorist in evolutionary biology could be imagined.

The point here is that, if ID wants to become accepted as part of evolutionary biology in the same way that Lynn Margulis's SET has become accepted, then ID supporters have to do the same thing she did: get out in the field and get your hands dirty, and get into the lab and do the same thing. Her ideas were just as unorthodox and unacceptable in 1969 as ID is now. However, she didn't put all of her effort into public relations and political propaganda. No "Symbiosis Institute" dumped millions into the production of deliberately distorted press kits and one-sided propaganda films. Legions of self-appointed experts whose only exposure to biology was in high school classes or what they read on Answers in Genesis or Uncommon Descent bloviated on SET and declared themselves experts after a week of superficial study of articles on Wikipedia.

No, Lynn and her colleagues did the hard work of finding the empirical evidence that eventually carried the day and established her SET as one of the bedrock foundations now worthy enough of respect as to earn the ire of the creationists and IDers. Her ideas are still radical, and still raise the blood pressure of many evolutionary biologists. Her dismissal of the "modern evolutionary synthesis" in particular is not popular among many evolutionary biologists, who are largely still mired in paradigms that are at least four decades of out of date. She has said some things about the "modern synthesis" that have brought smiles to the faces of the creationist quote-miners. The difference between her and them is that they can't even begin to claim any credibility in science; their "work" is entirely parasitic on hers, and deserves nothing but contempt.

When the history of evolutionary biology in the 20th century is written (I hope to contribute to it myself, if I live long enough), the work of Lynn Margulis will rank right up there with the work of Fisher, Haldane, Wright, Dobzhansky, Mayr, Simpson, Stebbins, Gould, Lewontin, Kimura, Williams, Hamilton, Trivers, and the two Wilsons. And unless and until IDers decide that it's finally time to stop doing agitprop and start doing science, they and the creationists will at best be a trivial footnote.

Evolution and Ethics: Is Morality Natural?


ANNOUNCEMENT: Seminar in History of Biology

AUTHOR: Allen MacNeill

COMMENTARY: Allen MacNeill

First the announcement, followed by a brief commentary:

I am very excited to announce the following course, to be offered this summer in the six-week summer session at Cornell University:

COURSE LISTING: BioEE 467/B&Soc 447/Hist 415/S&TS 447 Seminar in History of Biology

SEMESTER: Cornell Six-Week Summer Session, 06/24/08 to 07/31/08

COURSE TITLE: Evolution and Ethics: Is Morality Natural?

COURSE INSTRUCTOR: Allen MacNeill, Senior Lecturer in Ecology & Evolutionary Biology, Cornell University

COURSE DESCRIPTION: This seminar addresses, in historical perspective, controversies about the cultural, philosophical, and scientific implications of evolutionary biology. Discussions focus upon questions about gods, free will, foundations for ethics, meaning in life, and life after death. Readings range from Charles Darwin to the present (see reading list, below).

In 1871, Charles Darwin wrote in The Descent of Man "…the first foundation of the moral sense lies in the social instincts…and these instincts no doubt were primarily gained…through natural selection.” A century later, Edward O. Wilson, in
Sociobiology: The New Synthesis
, wrote “The biologist…realizes that self-knowledge is constrained and shaped by…natural selection. This simple statement must be pursued to explain ethics and ethical philosophers….”

And so it has: in the past few years the publication of hypotheses for the evolution of ethics and “the moral sense” has become an explosive growth industry and a hot topic of debate. In this seminar course, we will take up this debate by considering two alternative hypotheses:

(1) that ethics can be derived directly from human evolutionary biology, or

(2) that ethics can only be derived from philosophical principles, which are not directly derivable from evolutionary biology.

Included in this debate will be an extended consideration of the hypothesis that the capacity for ethical behavior is an evolutionary adaptation that has evolved by natural selection among our primate ancestors. We will read from some of the leading authors on the subject, including Frans de Waal, Paul Farber, Marc Hauser, T. H. Huxley, Richard Joyce, Elliott Sober, and David Sloan Wilson. Our intent will be to sort out the various issues at play, and to come to clarity on how those issues can be integrated into a perspective of the interplay between philosophy and the natural sciences.

In addition to in-class discussions, course participants will have the opportunity to participate in online debates and discussions via the instructor's weblog. Students registered for the course will also have an opportunity to present their original research paper(s) to the class and to the general public via publication on the course weblog and via THE EVOLUTION LIST.

INTENDED AUDIENCE: This course is intended primarily for students in biology, history, philosophy, and science & technology studies. The approach will be interdisciplinary, and the format will consist of in-depth readings across the disciplines and discussion of the issues raised by such readings.

PREREQUISITES: None, although a knowledge of philosophical ethics, evolutionary psychology, and general evolutionary theory would be helpful.

DAYS, TIMES, & PLACES: The course will meet on Tuesday and Thursday evenings from 6:00 to 9:00 PM in Mudd Hall, Room 409 (The Whittaker Seminar Room), beginning on Tuesday 24 June 2008 and ending on Thursday 31 July 2008. We will also have an end-of-course picnic on Friday 25 July 2008.

CREDIT & GRADES: The course will be offered for 4 hours of credit, regardless of which course listing students choose to register for. Unless otherwise noted, course credit in BioEE 467/B&Soc 447 can be used to fulfill biology/science distribution requirements and Hist 415/S&TS 447 can be used to fulfill humanities distribution requirements (check with your college registrar's office for more information). Letter grades for this course will be based on the quality of written work on original research papers written by students, plus participation in class discussion.

COURSE ENROLLMENT & REGISTRATION: All participants must be registered in the Cornell Six-Week Summer Session to attend class meetings and receive credit for the course (click here for for more information and to enroll for this course). Registration will be limited to the first 18 students who enroll for credit.

COMMENTARY:

Perhaps the most common fallacy in philosophy and science is the tendency to assume that because something is “natural” (whatever that means) it must, ipso facto, be “good” (whatever that means) as well. In
last summer’s evolution and history of biology seminar, we talked about this tendency at some length. This summer I intend to make it the primary focus of our discussions.

From a historical standpoint, the tendency to conflate “is” and “ought” statements has been one of the ongoing arguments about the implications of evolution ever since Darwin first proposed his theory in 1859. Indeed, Darwin himself wrote much on the subject, especially in The Descent of Man, and Selection in Relation to Sex, his second most popular (and controversial) book. It has also been one of the sources of both confusion and controversy about evolution today. In particular, evolutionary psychologists (among whom I number myself) have struggled with this problem, not always successfully.

Like last summer and the summer before, this is a fascinating topic and I hope that enough people will sign up for the course with opposing viewpoints on this subject to make for a very interesting and stimulating summer seminar.

So, watch this space; when the course blog goes up, I will announce it here and provide links to all and sundry. And remember:

"… the ethical progress of society depends, not on imitating [nature], still less in running away from it, but in combating it." – T. H. Huxley, Evolution and Ethics (1893)

Godwin's Darwin



AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

There has recently been a huge controversy generated around the upcoming movie, "Expelled: No Intelligence Allowed", featuring Ben Stein. Rather than rehash most of this, I recommend that those who are not yet "up to speed" check out the related posts at The Panda's Thumb.

Ben Stein (a former speech writer for Richard Nixon) interviewed many evolutionary biologists for this film, including Will Provine and me. As the various threads at The Panda's Thumb indicate, he did so under patently false pretenses. Then, when some of the interviews contradicted the particular propaganda point he was trying to make, those "inconvenient" interviews were cut from the film (see here).

But that's not what I want to talk about in this blog. Ben Stein has been quoted repeatedly as saying that the underlying message in "Expelled" is "No Darwin, no Hitler". Yes, this is a particularly egregious example of Godwin's Law, but it is cited so often by creationists and ID supporters that I have prepared the following refutation (including citations, most of which I found here) Enjoy!

While Hitler uses the word "evolution" in Mein Kampf, it is clear that he is not referring to Darwin's theory. Indeed, he never mentions Darwin at all. In fact, a look at his writings reveals his sentiments on the subject to be those of an orthodox creationist.

Like a creationist, Hitler asserts fixity of kinds:

"The fox remains always a fox, the goose remains a goose, and the tiger will retain the character of a tiger." - Adolf Hitler, Mein Kampf, vol. ii, ch. xi.


Like a creationist, Hitler claims that God made man:

"For it was by the Will of God that men were made of a certain bodily shape, were given their natures and their faculties." - Adolf Hitler, Mein Kampf, vol. ii, ch. x.


Like a creationist, Hitler affirms that humans existed "from the very beginning", and could not have evolved from apes:

"From where do we get the right to believe, that from the very beginning Man was not what he is today? Looking at Nature tells us, that in the realm of plants and animals changes and developments happen. But nowhere inside a kind shows such a development as the breadth of the jump , as Man must supposedly have made, if he has developed from an ape-like state to what he is today." - Adolf Hitler, Hitler's Tabletalk (Tischgesprache im Fuhrerhauptquartier).


Like a creationist, Hitler believes that man was made in God's image, and in the expulsion from Eden:

"Whoever would dare to raise a profane hand against that highest image of God among His creatures would sin against the bountiful Creator of this marvel and would collaborate in the expulsion from Paradise." - Adolf Hitler, Mein Kampf, vol ii, ch. i.


Like a creationist, Hitler believes that:

"God ... sent [us] into this world with the commission to struggle for our daily bread." - Adolf Hitler, Mein Kampf, vol ii, ch. xiv.


Like a creationist, Hitler claims Jesus as his inspiration:

"My feeling as a Christian points me to my Lord and Savior as a fighter. It points me to the man who once in loneliness, surrounded only by a few followers, recognized these Jews for what they were and summoned men to fight against them." - Adolf Hitler, speech, April 12 1922, published in My New Order.


Like a creationist, Hitler despises secular schooling:

"Secular schools can never be tolerated because such schools have no religious instruction, and a general moral instruction without a religious foundation is built on air; consequently, all character training and religion must be derived from faith . . . we need believing people." - Adolf Hitler, Speech, April 26, 1933.


Hitler even goes so far as to claim that Creationism is what sets humans apart from the animals:

"The most marvelous proof of the superiority of Man, which puts man ahead of the animals, is the fact that he understands that there must be a Creator." - Adolf Hitler, Hitler's Tabletalk (Tischgesprache im Fuhrerhauptquartier).


Hitler does not mention evolution explicitly anywhere in Mein Kampf. However, after declaring the fixity of the fox, goose, and tiger, as quoted above, he goes on to talk of differences within species:

"[T]he various degrees of structural strength and active power, in the intelligence, efficiency, endurance, etc., with which the individual specimens are endowed." Mein Kampf, vol. ii, ch. xi.


So, like a creationist, there is some evolution he is prepared to concede -- evolution within species, or "microevolution", to which people like Phillip Johnson and Michael Behe have no objection. It is on the basis of the one part of evolutionary theory which creationists accept that Hitler tried to find a scientific basis for his racism and his program of eugenics.

Ergo, Hitler did not base his eugenic and genocidal policies on evolutionary theory, but rather on views that are very similar to those held by most creationists and many ID supporters.

On the Problem of Pain


AUTHOR: Allen MacNeill

SOURCE: Original essay

COMMENTARY: That's up to you...

As some long-time visitors may be aware, I have not been able to update this blog for a long time. While part of this has been due to the press of other business, much of it has been due to two health problems, both of which have at their core what C. S. Lewis referred to as “the problem of pain.” Late last fall, and continuing until after the turn of the year, I suffered from a kidney stone. Then, in mid-January, my wife’s stepmother died of emphysema, and we drove 1,200 miles to be present at her funeral in Michigan. It was a hellish drive, through wind-driven lake-effect snow all the way from Jamestown to Toledo. I gripped the wheel with white knuckles and hunched my shoulders like a linebacker all the way.

The next day I awoke in agonizing pain, similar in quality to that produced by the passage of a kidney stone. But, unlike the kidney stone, the pain did not relent. It is still present, although finally it has begun to subside as the result of intensive physical therapy and the passage of time.

What kind of pain? Well, to be precise, it’s phantom pain. The cause (as far as anyone can figure out) is inflammation of the right lateral cervical nerve passing through a foramen between my sixth and seventh cervical vertebrae. To be precise, I have right lateral radial radiculopathy.

But that doesn’t describe what it feels like. Throughout most of the past two months it has felt like there is a cable of red-hot twisted steel running from the right side of the back of my neck, across the top of my shoulder and down the outside of my right arm to the middle three fingers of my right hand. This pain begins as soon as I wake up, and intensifies throughout the day until, after nightfall, it becomes overwhelming and the only thing I can do is take two oxycodone and lie down and wait for unconsciousness.

I describe all of this, not to elicit your sympathy, but to introduce “the problem of pain” from the standpoint of evolutionary biology. All of the rest of our senses have a physical referent: heat receptors sense heat, cold receptors cold, taste receptors sugars and ions and acids and bases and certain amino acids in our food, rods and cones sense the presence of light photons, etc. But pain receptors do not sense the presence of “pain.” No, “pain” is an “artificial sensation.” What pain receptors are adapted to sensing is cellular damage.

Why does pain exist? From an evolutionary standpoint, pain is “good for us”: in the past, those individuals who could feel pain would stop doing whatever it was they were doing that was causing the cellular damage that was triggering the pain, and therefore survived and reproduced more often than other individuals who did not feel pain so acutely. To be specific, individuals who had the cellular machinery to transform the chemical signs of cellular damage into action potentials in pain dendrites, and whose pain dendrites are connected to their central nervous systems in such a way as to cause changes in their behavior in such a way as to reduce such damage (and therefore reduce the amount of pain such damage causes) passed on to their offspring the genetic and developmental programs that produced the cellular machinery that made such responses possible.

But the problem with pain is that it doesn’t necessarily happen only when avoidable cellular damage is happening as the result of something we are doing. This is most obvious in the case of the two sources of pain that have crippled me for the past few months.

Kidney stone pain is widely recognized as one of the most intense forms of pain that we can experience. I know several women who have had babies and kidney stones, and they all assert that kidney stone pain is much, much worse. I know a couple of men who have had massive heart attacks and kidney stones, and they assert that kidney stone pain is worse (yes, the terror of having a heart attack is horrific as well, but terror is not pain, although the two are evolutionarily related). I have myself suffered various injuries, from chopping a wedge out of my shin with a macheté to breaking a bone to rather serious burns (especially on my fingertips) and none of them comes close to the pain of passing a kidney stone.

Yet, two questions immediately present themselves: why should passing a kidney stone produce pain at all, and why is the pain so intense? It is only via modern medicine that we understand what causes kidney stones; the most common cause is a familial tendency to produce very concentrated urine, combined with a genetically inherited defect in a couple of enzymes that in most people prevent the precipitation of calcium oxalate and/or uric acid crystals in the lumen of the pelvis of the kidney. Furthermore, the behavioral and chemical events that predispose one to forming kidney stones are so “detached” from the process of passing a kidney stone that they almost certainly cannot cause a person to stop doing whatever it was that resulted in the formation of the stones themselves.

Also, it is a general principle of the evolution of sensory systems that if damage to a particular tissue is virtually universally fatal, no pain receptors are present in that tissue. For example, there are no pain receptors in brain tissue; as my friend Will Provine can attest, people can probe around in your exposed brain tissue without causing the slightest amount of pain (he was fully conscious during the surgery in which his brain tumor was removed). You can literally stick an ice pick into a human brain and swish it around, and although it will cause massive neurological deficits, it will not cause any pain (this is how “ice pick” lobotomies used to be performed, generally without anaesthesia).

So why are there so many exquisitely sensitive pain receptors in the lining of our ureters? It would seem to me that damage to something as deeply embedded in the body as a ureter would almost certainly be fatal, and so why are there pain receptors in them? And why is the pain so extravagantly severe?

One possibility is that the pain receptors are there because people who did not have them would contort or twist their bodies so much during vigorous or violent activity that they might rupture or tear their ureters, resulting in their death. However, that doesn’t explain why a kidney stone the size of a grain of sand should cause so much pain passing down a ureter with the inside diameter of a pencil lead.

And so on to my cervical radiculopathy. In the case of my right arm pain (which at times has been nearly as bad as passing a kidney stone), there isn’t any damage happening in my arm at all. Rather, the pain is the result of physical stimulation of the pain fibers in the seventh cervical nerve as it passes through the foramen between the vertebrae. That is, there is absolutely no connection between anything I am doing (or have done) with my right arm that has caused cellular damage in my arm, which has then been transformed into action potentials in the pain dendrites going to my central nervous system.

That this is the case is encapsulated in the term “radiculopathy.” What is causing the pain is cellular damage in the “root” (or “radicle”) of the seventh cervical nerve, rather than cellular damage in my right arm. In the beginning stages, this damage was so severe that I also had fasciculations in my arm, shoulder, pectorals, rhomboid, and trapezious muscles. That is, these muscles twitched and contracted spasmotically and uncontrollably, as “phantom” nerve impulses generated in the inflamed motor neurons of the seventh cervical nerve stimulated those muscles to contract.

And so I had both “phantom” pain and “phantom” muscle twitching, for months. Did any of this convince me that I should no longer drive out to Michigan with my hands clenched to the wheel and my shoulders hunched. You bet it did, but that can’t possibly explain how generations of my ancestors could have evolved an anatomical or physiological arrangement that is so prone to such derangements. For, as it turns out, cervical radiculopathy is one of the two most common forms (the other being lumbar radiculopathy, or “low back pain”, which I – along with nearly all of you – have suffered from repeatedly).

Once again, is there any “reason” for all of this extravagant pain? C. S. Lewis, in The Problem of Pain, used an analogy with sculpting stone: that each “blow” of the pain we all feel is what “hammers” us into shape as people. That is, God gives us the ability to experience pain as a means of making us better people.

Well, what about “meaningless” pain, such as that which we experience in the case of passing a kidney stone or suffering from cervical radiculopathy? Believe me, I honestly don’t think either of these has made me a “better” person. On the contrary, they have made me a more exhausted, more tentative, more fearful person. Every hint of the return of such pain makes me cringe, and so only if God wants me to be a more exhausted, more tentative, more fearful person who cringes at the slightest hint of a kidney stone or returning arm pain does such an explanation make sense.

What makes more sense to me is that such pain is an unintentional side effect of a system that is otherwise adaptive. In a world in which cellular damage is an ever-present possibility, pain receptors have clear adaptive value. And if, under certain conditions, they produce “unnecessary” pain, that’s the price we pay for being adaptive.

For moral reasons, I tend to favor the evolutionary explanation. That isn’t to say that one can’t use unnecessary pain; I have consciously tied the pain in my arm to an exercise and weight loss program, which seems to be working so far (although I worry about what will happen when and if the pain in my arm finally goes away). But this is the result of a conscious and deliberate process on my part, to harness what would otherwise be a completely meaningless affliction to something I would like to accomplish, but have had difficulty doing in the past. Maybe that’s what Lewis is really saying as well, although I suspect not.

So, does the experience of pain make us “better people?” Only if we make it so, and then it isn’t the pain that is doing it, but rather our own determination to do so, which isn’t “natural” in any way.

Here’s wishing you all a happy (and generally pain free) New Year!
