The Principle of Least Astonishment: Deep Time and Human Time

"People look upon the natural world as if all motions
of the past had set the stage for us and were now frozen
. . . To imagine that turmoil is in the past and
somehow we are now in a more stable time
seems to be a psychological need. Leonardo Seeber
. . .referred to it as the principle of least astonishment.
As we have seen, the time we are in
is just as active as the past. "
--Eldrige Moores, Tectonist;
from "Assembling California",
in Annals of the Former World, by John McPhee



Years ago, before I studied biology in graduate school, I graduated with a degree in Geology with Honors from a stable university on the continental craton. Although I ended up in a different field, my knowledge of geology has made the history of North America come alive for me in my travels across the continent over the course of the past 30 years.

Photo: Unconformity between the Tertiary volcanics of the Datil-Mogollon Volcanic field and the underlying Mesaverde shales and sandstones. The lavas were extruded during Eocene-Oligocene time (beginning approximately 28 mya). This unconformity is exposed in the wall of the Zuni Plateau north of the Zuni Salt Lake, Catron County, NM.

Browsing in the trade books section of the university bookstore one day during my senior undergraduate year, a title caught my eye: In Suspect Terrain, by John McPhee. A reproduction of a painting of the Delaware Water Gap graced the cover. It was a book of essays about geology and the plate tectonics revolution from the perspective of the USGS's conondont specialist at the time, Anita Harris.

The title caught my eye, because Skip Nelson, our structural professor, had been discussing with us the concept of "suspect terranes", pieces of the geology of a region that have a different geology from the adjacent country rock, and the origins of which are suspected to be from elsewhere on earth. In those early days of the theory of Plate Tectonics, little was known about suspect terranes, and it was hard to see how such terranes fit into the theory. Much arm-waving--the speculations of scientists scratching their heads together--became stories,and then hypotheses that had a decent chance of being tested as the both the science and the technology that supported it advanced over the years. But at that time it was still arm-waving and stories.

Of course I had to buy the book. And in rooting around a bit more in the same section, I ended up buying McPhee's first book on the subject, Basin and Range, as well.

I had gone into geology in 1979, after hearing about plate tectonics from my English professor at a small private liberal arts college. A transfer to the state university was required once my passion was ignited and my interests revealed. (That English professor saw that I was less than passionate about the liberal arts, and being somewhat of a curmudgeon, Dr. Pierson had written on one my papers: 'Does college bore you?' I was a little hurt at the time, because the truth hurts when one is trying to make the best of a bad college decision, but I was grateful to him later). The early '80's, as the revolutionary theory of Plate Tectonics was maturing in the field, was an exciting time to be thinking about geology and earth history, and I was captivated.

As I went through the spring semester of my senior year, with field trips to Missouri, Wisconsin and Ohio, I was also reading about the rise of the Basin and Range, the possible docking of micro-terranes on eastern North America, and the problem of overgeneralizing from theory without benefit of working field experience with the actual rocks. Reading McPhee and my texts in historical geology, stratigraphy, sedimentology, and structural geology became an obsession that took precedence over everything else. (I got a "C" in communications--required to "round out the degree"--which did not even upset me as it otherwise might have done).

Later, as a young mother chasing after a very energetic two-year old, I discovered McPhee's third book in the series, Rising from the Plains, about the Grand Old Man of Rocky Mountain Geology, David Love, whom I had met briefly during a field camp a few years earlier. Although my later interests and experiences, as well as the need to support my children by myself, took me in other directions, I maintained my interest in Geology. Recently, I found McPhee's Annals of the Former World, which contains the three original books about Geology,with updates and two new books, one on the geological origins of California, and one on the pre-Cambrian rocks that underly the sediments of the stable craton of North America.

Our move to the Ragamuffin Ranch, where the geology of the Colorado Plateau stands out in the Datil-Mogollon Volcanics, caused me to want to pick up Annals for a second time, and as with every really good book one re-reads, I noticed certain parts anew. In this case, I was thinking about the problem of dogmatism in science, encouraged both by scientists whose funding is politically motivated, and by non-scientists who confuse initial arm-waving with a testable hypothesis, and who take it to be the same as truth handed down from Sinai. "The science is settled," says one of the latter about one such arm-waving idea. But the science is rarely settled so early in the life of an idea.

Geology is by its nature a big-picture science, and one that depends a great deal on inference from what can be observed to how it got to be the way it is. Whereas much of science as practiced within the dominant paradigms of each scientific field today is deductive, the big-picture thinking about Geology is necessarily inductive. (Despite the turf wars about these two methods of discovery, both deductive and inductive thinking are necessary for a complete science). Further, Geology--by the nature of its subject matter--is primarily about TIME. Lots and lots of time. Or as geologists say it, "Deep Time". Time that is orders of magnitude greater than the span of a human life, or even the span of numerous human generations. The kind of time that geologists tend to discuss makes a million years appear as the blink of an eye, and the entire time of human existance on the earth is scarcely longer than that.

The disconnect between Deep Time and Human Time leads to some interesting human misconceptions about our power and place upon the planet. On the one hand, human beings are the first species upon the earth that have become self-referencing observers of the evolution of life on the planet. We are capable of thinking about and questioning the way life came to be here, and our place in that parade of "endless forms most beautiful". We can think about the meaning of our existence and we know the finite nature of our lives. All of this makes us important to ourselves, and perhaps, as an aspect of the universe that observes itself, we are important in the grand scheme of things.

But this disconnect between Deep Time and Human Time also leads to the idea that we are the culminating act of evolution: that our existence was the necessary end of a long chain of programmed events. It is rather like the paint on the Eiffel Tower believing that the tower was built for its own sake, as Mark Twain once remarked. Enter Seeber's Principle of Least Astonishment, which is the idea that all of what we see around us is the culmination, that now that human beings walk the earth, change should stop because evolution is finished. The continents are in their final place, the species that exist now shall exist forever, the climate that we have been born into shall not change. So we have written, and so shall it be done.

Evolution has no teleological direction. It is the response of organisms adapting to and failing to adapt to changing environments over time. This leads to changes in the gene frequencies within species, and that is evolution. If we were able to rewind and replay the course of the evolution of life upon the earth, there is no guarantee that the results would be the same as we now see; there are too variables along the way. Species that have the genetic wherewithal to meet and survive environmental change evolve. Those that do not become extinct.

And so it becomes somewhat amusing to watch as those who believe that they understand evolution, those that make fun of the Creationists and call them "neanderthals", are also those that have turned science into a political agenda and have begun an effort to "Stop Global Climate Change" by legislation. They have about as much chance of success as they do to "Re-Unite Gondwanaland!" (Both quotes can be found on bumperstickers.The first appears to be serious, and the second is geological tongue-in-cheek).

Even geologists get pulled up short by the disconnect between Deep Time and Human Time. And even though they predict that when the two kinds of time intersect, as they did during the Great San Francisco Earthquake of 1906 and the Tsunami of 2004, turmoil becomes inevitable, we still tend to think that the earth should behave itself and stay still beneath our feet. We tend to want the species that existed when we were born to be there when we are old, and glaciers should neither retreat nor advance so long as human beings live upon the earth. We think of disasters as a nasty interruption of "normal" rather than a "normal" feature of a dynamic planet.

Never mind that we owe our big brains to the last ice age. Never mind that climate has been changing upon the earth since before the oldest rocks we can find on the continents existed. And never mind that life on the planet has had an effect on its environment since the oxygen revolution.

From the perspective of Human Time, an earthquake, a tsunami, a volcanic eruption, are all potential disasters. And it makes sense to think of them as such. Human beings are meaning-making individuals, and we view events from the perspective of their meaning to us.
And that is necessary and--dare I say it?--normal to our evolutionary niche. And if we can predict and protect ourselves from disaster, this is a good thing for us. But when put into the perspective of Deep Time, such disasters, even ones on a extinction-level scale, are more grist for the mill of evolution--the change over time of life on earth.

The Principle of Least Astonishment may indeed by a psychological necessity for going about the daily business of living. And yet now and then, the view from the perspective of Deep Time creates for us the Most Astonishment, it creates wonder at the precious nature of our existence, birthed on the edge of the creative maelstrom and able to look into it and see the circumstances of our genesis. Wonderful life, indeed!

Glenn Beck's Monkey Show: This View of Life


"There is grandeur in this view of life, with its
several powers having been originally breathed
into a few forms or into one; and that whilst this
planet has gone cycling on according to the
fixed law of gravity, from so simple a beginning
endless forms most beautiful and most wonderful
have been, and are being, evolved."

--Charles Darwin, 1859: On the Origin of Species


In my second entry on the topic of Glenn Beck's misapprehension of the theory of evolution, I discussed the fallacy that he spoke on his radio show; the idea that humans evolved from monkeys, or even from apes. Darwin's theory does not posit this idea at all; rather human beings, as well as the great apes, have descended from some common ancestor that in certain features and functions resembles us both, however remotely. But I am not quite done, because another idea was expressed, later in that same hour of the radio broadcast, that is also fallacious: Glenn Beck's claim that collectivists require Darwin's theory, because they must have a view of human individuals as endlessly malleable and therefore perfectible by other humans or, in the case of socialists and outright communists, by some unspecified "social force" that generally turn out to be a force perpetrated by tyrants.


This idea turns on another common misunderstanding of Darwin's theory, one that became a force in American politics at the end of the 19th century, the idea called "Social Darwinism."
Social Darwinism can be defined as any number of political ideologies that use Darwin's theory to suggest that societies evolve in the biological sense and that certain individuals in society are more "evolved" than others, and that they have an obligation to direct human evolution to specific ends. This ideology has nothing to do with the Darwinian theory of evolution by natural selection, except the usurpation of Darwin's name. And in Darwin's name, a whole host of fallacies have been developed to limit human freedom: the Nazi concept of the Obermenschen (supermen) is one, and so is the American progressive idea that a better citizen can be bred through eugenics.

Social 'Darwinism' includes two fallacies that make the ideology foreign to Darwin's theory. The first is that societies evolve biologically, meaning that society is an entity that natural selection acts upon, and that action changes gene frequencies due to various social pressures. The second is that Darwinian evolution is goal directed, and that natural selection is more than a mechanism, that in some way it is working to a specific, predetermined end.

I think the first fallacy is driven by a complete misunderstanding about how Darwinian evolution is defined, and the second by an equally powerful misapprehension about how natural selection works.

A society is nothing more than a grouping of individuals that are distinguished by location, and perhaps by a shared nationality and culture. There may be numerous social groups in that larger amorphous thing that we call society, and those different subsets may very well have their own unique subcultures and value systems. There is not much that defines a society except the obvious: that members of a society tend to socially interact with one another at some level. A society is not some mystical synergistic whole. It has no self-awareness and no will. If societies evolve, those changes are not biological, and they are not driven by natural selection.

Natural selection acts on the relatively fixed phenotype (the way that genes are expressed) of the individual, producing change over time in biological populations. That evolution--for change over time is what the word evolution means--is measured by the change of gene frequencies in a population over time. Individuals do not evolve, but biological populations do. A biological population is not some random group of individuals that interacts socially. Rather it is a group of individuals that can and do interbreed with one another. That they can interbreed means that they are members of the same species, but being a population means that these individuals have access to one another for the purpose of reproduction. Thus alleles (specific forms of each genes) are spread around that population. There are numerous biological populations of human beings on the earth, separated by geography and by culture and by language, which are but different barriers humans have to reproduction with one another. None of these barriers is perfect, and by migration of individuals from one population to another, novel alleles are introduced to populations, changing the gene frequencies in each population. Thus, evolution is always occurring.

When I said above that natural selection acts on individuals, I meant that the genetic traits of an individual vary in expression, creating as many unique phenotypes as there are individuals. Within a given environment, some expressions of a trait will lead to a robustness that allows an individual to survive and pass on those traits, while other expressions of the same trait may--in that same environment--lead to a weakness that means an individual does not live long enough to reproduce, or reproduces less often. Evolutionary "fitness" is defined as the number of offspring an individual has, thus influencing how many copies of the allele is passed on into the next generation, thus spreading through the population in greater or lesser numbers.

It is environment that effects the fitness of a certain trait. A trait that creates an effect that leads to the allele being passed on in great numbers in one environment, may have no such effect in another environment, or may be deleterious to the individual that carries it in a third environment. For example, the recessive allele that blocks the deposition of pigments in the eye, caused the blue-eyed phenotype, has no effect in northern climates, where the solar angle is low, but in equatorial locations, it results in a much greater risk of cataracts and cancer at a younger age. Thus one might expect to find more of the recessive "blue-eye" alleles in northern populations than in equatorial ones. Since there may be more than one direction of pressure on a trait (or suite of traits) at any given time, the end result is a variety of expression, creating those "endless forms most beautiful" of which Darwin spoke. In any given species in any given environment, not all traits are under selection at any given time. It really depends on the variety of alleles, and upon the rate of environmental change that a species may be experiencing. The point here is that fitness is not some fixed array of parameters that have been ranked by some conscious process of choosing. It is simply what variations on a trait, among those present, are most beneficial to the differential reproduction of the individuals within a population that carry them.

And this brings me to the second fallacy held by the Social "Darwinists": the fallacy that evolution has some direction, some predetermined end. Since natural selection acts on the variations of a trait that happen to be present in a given population at a given time, there can be no "goal" for evolution. If, as Stephen J. Gould used to say, we could rewind the tape of the evolution of life on earth and begin it again, we would not see the same movie. Evolution would likely run a wildly different course.

There is a random element to Darwinian evolution, and this is why species eventually go extinct, ending their contributions to the future of life on earth. Sooner or later, a variation on a trait that would allow a species to get through a certain set of environmental changes will not be present in any of the biological populations of the species; or else there will not be time for a beneficial variation to spread through the population, and the species will die out. Just as death is part of every individual life, extinction is the destiny of every species.

I think that this lack of direction, this randomness that exists in our being here at all, in how species come and go upon the earth, is the most unsettling idea about evolution of all for many people. It certainly changes one's view of one's place in a very large and random universe. And yet, it also magnifies the uniqueness of each individual life on earth, and places a premium on human self-awareness, which is what sets our species apart from the other lives that share our planet.

Since evolution has no direction, and since no individuals in a species are "more evolved" than any others, two things are true. One is that there is no perfection awaiting the future of human life on earth. We are what we are, and as human beings we exist within certain parameters that make us human. Although we are all unique, our uniqueness exists as variations on the theme of human being. Individuals do not evolve. Each of us can only play the genes we were dealt. The second truth is that no human beings are wiser than any others in their ability to know how to shape human evolution to certain ends. There are no philosopher-kings who can see outside the cave, and select for certain traits in order to bring the rest of us to what they believe is their level.

The Social "Darwinists", who have arrogantly arrogated to themselves the role of gods and goddesses, do so using a perversion of Darwinian evolution in which selection is anything but natural, and fitness is defined as those traits they most admire in themselves. Traits that may have very little to do with the traits that are actually under selection in different human populations. Unfortunately, there are those--like Glenn Beck--who have so little knowledge and understanding of Darwin's theory, that they equate the unifying theory of modern biology with an ideology that is based on a misunderstanding of evolution by natural selection; an ideology that is as profoundly wrong as are the misperceptions of the creationists. This is what I mean when I say that the leftists and the collectivists are often equally as ignorant of Darwin's theory of evolution as are those on the religious right.

But I believe the collectivists on the left are the more dangerous. The creationists are for the most part reacting to the usurpation of their power to pass their religion on to their children. All of the equal-time debates, all of the legal challenges they make are in response to public education. If creationists were no longer forced by law to pay for their children to be instructed to accept an idea that they believe is against their religion, there would be no debates and no legal battles. But those on the left believe that they have some mandate to act as those who would select out the traits that they believe do not contribute to the perfection of humanity in the next great step of "social evolution." But all such traits originate in the phenotype of individuals, so this means that certain individuals must be selected out. This is what Justice Oliver Wendell Holmes, a notorious progressive, understood his role to be when he ruled that a woman could be forcibly sterilized for the good of the State, saying:

"It is better for all the world, if instead of waiting to execute degenerate offspring for a crime, or let them starve for their imbecility, society can prevent those who are manifestly unfit from continuing their kind." (Buck vs. Bell, 274 U.S. 200 (1927).

Here Holmes imagines himself to be the agent of selection, a selection that is not at all natural. He further implies that there is some direction to evolution, that a certain kind of human being--his kind--has some destiny that is the pinnacle, the perfect end of evolution. An end that would result in a deadly sameness, in which there would be no variation for natural selection to act upon. An end that would result in destruction and death, as it always does. An end that would result in the ultimate extinction of the human species from the face of the earth.

Nothing could be further from the true nature of Darwinian evolution by natural selection. This view of life predicts infinite variation in infinite combinations developing over time from so simple a beginning. There is indeed a grandeur in it, a grandeur that is missed by all of those who misapprehend the beauty of life on earth in all its wonderful variety.

Glenn Beck's Monkey Show: Not Even Wrong

“Even my fellow biologists are unacquainted with the
many lines of evidence for evolution, and most of
my university students,who supposedly learned evolution
in high school, come to my courses knowing almost nothing
of this central organizing theory of biology.”

--Jerry A. Coyne; Why Evolution is True. 2009.

In my last blog entry, I gave an overview of the problems I heard in Glenn Beck's latest attack on the theory of evolution by natural selection. To recap briefly, those problems are errors in knowledge, distractability from the main point and reason for the discussion, and philosophical errors at the level of premises, reasoning and argumentation. The blog entry can be found here.

In this blog entry, I will discuss Glenn Beck's misapprehension of the modern theory of evolution because it is not even wrong. By this I mean that Beck's argument on his show, that evolution cannot be true because he has never seen a half-monkey, half human, is so off the mark that it is not even an argument. It is a straw-man, and does not rise to the level of an argument that can even be discussed. The phrase implies that even an argument that is wrong, would be better than this one.

What I am not going to do is try to convince anyone that the theory of evolution is true. I accept the evidence for evolution, which is so varied, so strong and so convincing that its reality is not even a casual discussion among biologists. However, there is so much evidence, on so many levels and coming from so many fields in the natural and physical sciences that it would take more than one book to recount it all. The interested reader can begin with Jerry Coyne's book, cited above, and continue with many well-written and documented books in the popular scientific literature. There is also another reason, and that is that is useless to argue either major or minor points of the theory, citing evidence, when the real problem is on a different level. That is, most people who refuse to accept the evidence for evolution by natural selection do so not because of this or that point has not been adequately addressed, but because he or she has a religious view of the world that includes biblical literalism, which is incompatible with most of modern science. Argumentation without a general agreement on world view is futile. And I believe that the problem is a political one and not scientific at all, and as a libertarian I do not believe that it is my place to use the force of law to change another's beliefs. I have written my opinion about the issue of evolution and science education here .

Glenn Beck's problem is not that he does not accept the evidence for the theory of evolution by natural selection. Although it is clear that he does not. His problem lies in that he attacked the theory citing a half-baked non-observation as evidence against it, and that indicated to anyone who knows the theory well that he does not know it or understand it in even the most rudimentary sense. This is not uncommon – as Coyne indicates in his book (quoted above). The purpose of this blog entry is not to change anyone's mind about evolution, but to discuss this common error that becomes the logical fallacy commonly called “the straw man argument” with amazing frequency.

The sum total of Glenn Beck's argument against evolution was that it was not likely to be true because , he said, “I haven't seen a half-person, half-monkey, yet.” When this statement came out of Beck's mouth, I shouted “Thank you, Bishop Wilberforce!” at the radio, because this was so reminiscent of the early arguments against evolution. From that time until this, the caricature of a blend of two species is, well, specious. It is a straw man put up in order to mock the opposition and to implant in the minds of listeners (or at least those who are ignorant of the actual theory of evolution) an idea that has never been a part of Darwin's theory of evolution by natural selection. Either Glenn was not paying attention during his high school biology class--a distinct possibility--or he is intentionally making a mockery of the theory in order to woo the most ignorant of his listeners. This second motive is also a possibility, however, it was not well-thought out, for in so doing he probably caused the majority of his listeners (including a NY News Tea Party reporter here) to do a double-take.

For those who have forgotten, or those who have never learned it, here is the theory of evolution by natural selection in a nutshell: The variation that we see among living organisms today arose gradually over time, brought about by a process called natural selection. There are five ideas that are necessary to any explanation of Darwin's theory and they are: evolution, speciation, the common ancestry of all life, natural selection, and gradualism. Evolution means change over time, and according to evolutionary theory, those changes in the genetic code of existing populations that create traits that give certain individuals a reproductive advantage – that is, traits that make it more likely for that individual to survive to reproduce – will become more common in the population over time. This change in the gene-frequencies of a population indicate that it is evolving.

Most of the time these changes in gene-frequencies occur naturally over time because successful reproducers pass those advantageous traits to their offspring, whereas those individuals who do not successful reproduce have no effect on the future genetic makeup of the population. This is natural selection*. Speciation usually occurs because enough variation occurs between two populations of the same species that they can no longer reproduce with one another. This is usually due to two populations being isolated from one another for some reason. Although speciation is arguably the most spectacular of the phenomena that the theory of evolution by natural selection explains, it is not the only one, or even the most common. But speciation is an effect of natural selection that has occurred many times over the history of life of earth, and that does mean that all species share a common ancestry; that is a link with every other species that is either a close relationship or a distant one, depending on how far back in the history of two species the divergence occurred.

*Although natural selection is by far the most common mechanism for evolutionary change in a population, it is not the only one: others such as gene-flow among populations, and the loss of genetic variation due to population bottlenecks and founder effect do have some influence.

For the purposes of our discussion about Glenn Beck's straw-man, the most important word in the paragraphs above is population. Populations evolve, individuals do not. That is because an individual's phenotype is fixed by the particular genotype he or she inherited. Some changes in gene expression do change over the lifetime, but an individual does not suddenly acquire half a genome from somewhere else. Therefore, one would not expect to ever see an individual that displays half the phenotype of one extant species and half the phenotype of another. Rather, if a biologist predicts that two species are closely related, she then expects to find many common traits between, and some important differences. Those common traits point to an ancestor species that is common to both of the related species. That ancestor species may or may not still be flourishing on earth. Extinction is also an important phenomenon that is predicted by the theory of evolution by natural selection.

With respect to human beings, monkeys do share common ancestry, which is indicated by enough common traits so that both monkeys and human beings are in the same taxonomic order: monkeys and humans are both primates. However, the most closely extant species to which humans are related are the great apes, all of whom are classified in the same taxonomic family – hominidae – which means “human-like”. The closest extant related species to humans is the chimpanzees. However, this does not mean that humans evolved from chimps. Nor does it mean that one should expect to find a half-chimp, half-person in the fossil record. Rather what we do find is that humans and chimps show a greater than 98% commonality in our genomes. We have enough traits in common to know that we had a common ancestor that walked the earth rather recently.

Another facet of Glenn Beck's mistake is that he equates some form of Lamarckism, the idea that evolution occurs by the passing of acquired traits to future generations through the genome, with Darwin's theory of evolution by natural selection. If this occurred, then one could say that individuals evolve. This is a philosophical mistake that Glenn actually shares with the communists, who promoted the neo-Lamarckian ideology proposed by Lysenko. This fallacy is necessary to the modern collectivists, but the Darwinian theory of evolution is not. Darwinisms is in fact at odds with it. But that discussion is part of the next blog entry on this topic. Stay tuned!

Glenn Beck's Monkey Show: Overview


"A little learning is a dangerous thing;
Drink deep, or taste not the Pierian spring:
There shallow draughts intoxicate the brain,
And drinking largely sobers us again."
--Alexander Pope: Essay on Criticism. Part ii. Line 15
.



If a little learning is dangerous, then no knowlege at all can be positively deadly. Or at least, embarrassing.
Yesterday, Glenn Beck made a fool of himself on his radio program.


As with many bright people, he did so by assuming he understood something that he did not. He did what he tells his audience not to do by making a judgment about a scientific theory on the fly, and it was clear that he had no clue what the modern theory of evolution actually is and what it is not.


For the record, I listen to Beck several times a week, although I have been listening less and less this fall because it is getting harder and harder to actually hear Glenn make his point. This is because in the past year he has brought on a friend from Texas, Pat Gray, who generally distracts Glenn from his more serious points, causing a number of listeners, including me, to reach for the dial. Pat Gray appears to be far less thoughtful than Glenn, and is clearly not as well read. When the banter begins, it devolves quickly and the show becomes frustratingly difficult to follow, and downright silly. I don't have time for that, and clearly from discussions with other thoughtful patriots, neither do they.


That said, it is quite clear that Glenn Beck is not stupid, as many of the leftist blogs claim. The so-called discussions of this issue at places like the Huffington Post come across as equally ignorant and worse, devolve to ad hominen statements. There is a large difference between rational disagreement and the kind of mean-spirited, angry, profanity-driven drivel that the lefties regularly spew out against Beck. However, this does not excuse Glenn from the equally ignorant attack on the theory of evolution that he made during a clearly ADD hour on his show yesterday.


Most laymen do not understand the modern theory of evolution. It is not that it is not understandable or even all that complex, though wading through the plethora of evidence for it takes time and study. It is that it has either been taught badly or not taught at all. This is the fault of the generally poor science teaching that goes on in America's K-12 institutions, private and public. With very few exceptions K-12 science education has treated the discipline as a series of disconnected facts that must be committed to memory and regurgitated, rather than as a method for discovering how the physical universe works using observation through our senses and their extensions. It is also the fault of a political divide that has been handled badly by scientists, creating a hostility towards all science among those who are expected to pay for it all without having the faintest idea of what it actually is. (I will have more to say about this later).


Collectivists and progressives at the extremes of both political parties have seized on this divide, and have used it to their own political advantage. On the right, it has been used to promote a kind of populist know-nothingism that lets those pols manipulate the religious passion of their constituents for Christian dominionism and theocracy. On the left, it has been used to promote an agenda of thinly disguised eugenics in which a scientific theory has been hijacked to bolster a collectivist ideology and a socialist agenda. (I have already said a bit about this here). It is clear that neither left nor right has the intellectual high ground here, nor the moral decency to promote and appreciate thoughtful and intelligent ideation among their constituents. A pox on both their houses!


Glenn Beck's ignorant diatribe betrayed several problems. One is that his notion of the scientific theory of evolution betrays an ignorance not only of the theory itself, but of science in general, and how the work of science is done. It is clear that because he has heard twaddle from equally ignorant others, he believes he knows what it is without having actually studied it. He would not make such statements in regard to areas he actually knows something about. So he has made an error of knowlege compounded by a certain ignorant arrogance, in that he did not question his lack of education in the field of science. Clearly his motto to "question everything" was left behind as he thoughtlessly spewed forth, compounding his embarrassment of ignorance with every sentence.


Glenn also has a problem organizing his thoughts that was clearly evident here, and in other monologues. His reasoning starts out with a good series of propositions and then his thinking stops at a certain point, and he rarely gets to the logical conclusion of his thought. Often he makes connections that seem to be leading somewhere interesting, and then he veers off, unable to complete the line of reasoning. He stops short and leaves his listeners in confusion or yelling at radio, "finish it, man!" Part of the problem here is the aforementioned Pat Gray, who nit-picks unimportant diction rather than letting the reasoning come to the conclusion of thought before cleaning up the proposition. Another part of the problem is that ADD that I mentioned earlier. Glenn has made no secret of it, as indeed he can't. Glenn distracts himself, going down rabbit-holes, and on snipe-hunts of thought, chasing extraneous thoughts prior to making a conclusion. And being that distractable means that the conclusion is never made.


Finally, Glenn Beck has a philosophical problem, and this is the most important. Although he reasons well up to a point, he often cannot bring the conclusion home, because he cannot or will not take his ideas to the most logical conclusion. This is not limited to his attacks on science, but can also be heard in other topics he discusses. For example, if Beck really believes in the sovereignty of the individual, which is clearly stated in the 9 Principles of his 9-12 project, then he cannot continue to advocate for the social control that is part and parcel of conservative political thought. Although he says that he is libertarian in thought, and that he trusts the American people, he cannot quite match his thought to those words. Lately, as Glenn has become increasingly a preacher in the Great Awakening style of Jonathan Edwards or George Whitfield, I have begun to suspect that this inability to bring home the most logical conclusion to his chain of reasoning may lie in the contradiction between the idea that human beings are fit for liberty, and his religious notion that man is fatally flawed by original sin.

Two of these problems are weighty enough to deserve blog entries of their own, and so I shall go into much more detail about Glenn's fundamental misunderstanding and ignorance with respect to the modern theory of evolution in my second part. In the third, I shall address the philosophical knots he mananged to contort himself into with his claim that those who accept the evidence for evolution by natural selection must deny the inherent nature of the rights of man. The ignorance of the first leads directly to the ignorance of the second. That is, the misunderstanding and misapprehensions that Glenn speaks with regard to what Dennett calls "Darwin's dangerous idea", lead directly to his ignorance of the history of the idea, and the wicked stepchildren it has been distorted to create: Social Darwinism and Lysenkoism. The first, in the hands of the American Progressives, gave us eugenics and forced sterilization, and the second, in the hands of Soviet Communists, gave us the planned famine that killed millions of Kulaks.

These discussions are worth taking a bit of time and blog-space to have, because the issues that Darwinian evolution bring up, and the ignorance of what the theory actually means, is widespread, and not limited to one political pole. If the religious right has used such ignorance to advance their cause of social control, the left has turned a scientific theory into a dogma and ideology to be decided not by the evidence, and not by hypothesis testing, but through the ideology of consensus science, something that never was and never can be. This has grave implications for new and unfounded pseudo-scientific theory that is more akin to religion than it is to science: global warming. The secular, collectivist left is using this idea to advance their own agenda of social control. And the implications are just as totalitarian as anything your hot-farting fundamentalist dominionist can dream up.
