Does consciousness refute materialism? The Chronicle of Higher Education promotes woo

April 1, 2014 • 7:21 am

For some reason the Chronicle of Higher Education, a weekly publication that details doings (and and available jobs) in American academia, has shown a penchant for bashing science and promoting antimaterialist views (see here for a piece defending woo-driven evolution). I’m not sure why that is, but I suspect it has something to do with supporting the humanities against the supposed creeping incursion of science (“scientism”).

That’s certainly the case with a big new article in the Chronicle, “Visions of the impossible: how ‘fantastic’ stories unlock the nature of consciousness,” by Jeffrey J. Kripal, a professor of religious studies at Rice University in Texas.  Given his position, it’s not surprising that his piece is an argument about Why There is Something Out There Beyond Science. And although his piece is long, I can summarize its thesis in two sentences (these are my words, not Kripal’s):

People have had weird experiences, like dreaming in great detail about something happening before it actually does; and as these events cannot be explained by science, the most likely explanation is that they are messages from some non-material realm that we cannot understand. If you combine that with science’s complete failure to understand consciousness, we must conclude that materialism is far from being all there is to the universe, and that our brains are receiving some sort of “transhuman signals.”

That sounds bizarre, especially for a fairly distinguished educational journal, but anti-materialism seems to be replacing postmodernism as the latest way to bash science in academia. Every opponent of “scientism”, for example, seems to cite Thomas Nagel’s recent book, Mind and Cosmos: Why the Materialist Neo-Darwinian Conception of Nature Is Almost Certainly Falseas if it were authoritative, never noting that that book was roundly trounced by academics. (Nagel’s book argues that evolution is driven by some non-Goddy teleological and non-material forces that science can’t fathom.)

Kripal begins his essay by recounting two anecdotes (one by Mark Twain) about how people sensed other people’s deaths, and accurate details of how it happened, before they knew about the deaths. Read his piece for the details, which are indeed striking. And Kripal says that these incidents of precognition are common, suggesting that there’s something out there that science can’t explain. (He doesn’t, of course, note the more frequent instances of “precognition” that don’t come true.)

I’ll give a few quotes showing how Kripal proceeds from these anecdotes to his main “X-Files” thesis:

The early-Victorian researchers had it right: They called dreams like the two with which I began “veridical hallucinations,” or hallucinations corresponding to real events.

We are not very good at such paradoxical ways of thinking today. We tend to think of the imagined as imaginary, that is, made up, fanciful. But something else is shining through, at least in these extreme cases. Somehow Twain’s dreaming imagination knew that his brother would be dead in a few weeks—it even knew what kind of bouquet would sit on his brother’s breathless chest. Similarly, the wife’s dream-vision knew that her husband had just been killed and where his body lay. In those events, words like “imagined” and “real,” “inside” and “outside,” “subject” and “object,” “mental” and “material” cease to have much meaning. And yet such words name the most basic structures of our knowing.

Or not knowing.

Kripal then discusses why laboratory tests of paranormal phenomena—tests like the “remote viewing” study that didn’t get the million-dollar Randi Prize at last summer’s JREF meeting—invariably fail. The usual excuse among advocates of woo is that the lab somehow ruins the vibes that create ESP, telekinesis, and the like. But Kripal, in the good tradition of these pseudoscientists, has his own explanation:

Putting aside for the moment the fact that psychics sometimes do get rich, and that statistically significant but humble forms of psychic phenomena do in fact appear in laboratories, the answer to why robust events like those of Twain, the widowed wife, and the Stockholm fire do not appear in the lab is simple: There is no trauma, love, or loss there. No one is in danger or dying. Your neighborhood is not on fire. The professional debunker’s insistence, then, that the phenomena play by his rules and appear for all to see in a safe and sterile laboratory is little more than a mark of his own ignorance of the nature of the phenomena in question. To play by those rules is like trying to study the stars at midday. It is like going to the North Pole to study those legendary beasts called zebras. No doubt just anecdotes.

Context matters. Methods that rely on or favor extreme conditions are employed in science all the time to discover and demonstrate knowledge. As Aldous Huxley pointed out long ago in his own defense of “mystical” experiences suggestive of spirit or soul, we have no reason to deduce that water is composed of two gases glued together by invisible forces. We know this only by exposing water to extreme conditions, by traumatizing it, and then by detecting and measuring the gases with technology that no ordinary person possesses or understands. The situation is eerily analogous with impossible scenarios like those of Twain, the wife, and the Swedish seer. They are generally available only in traumatic situations, when the human being is being “boiled” in illness, stroke, coma, danger, or near-death.

This comparison is unbelievable. Really? Comparing extreme physical conditions imposed on matter in the lab to human trauma? And, of course, there’s no reason why those “messages from the beyond” have to involve trauma, nor does Kripal explain why. And he doesn’t explain why all the great majority of people who die or suffer in the absence of their loved ones don’t send transhuman signals conveying their distress. Do they lack the right kind of transmitter?

In fact, as Kripal suggests above, he thinks “psychics sometimes do get rich”— his response to the frequent question of why psychics eke out a middle-class existence when, with their powers, they could make a killing on the stock market. (Actually, contra Kripal, I don’t know any people who have, at least by using their psychic powers. And why can’t psychics predict other things, like where the Malaysia Airlines jet is? After all, they’re not doing this in the lab.

Kripal’s agenda then becomes clear: he’s sick of those damn scientists telling everyone that matter and energy are all there is, and that, based on its record, materialistic science is likely to be able to explain all natural phenomena. (In principle, of course, since we don’t have the data to explain everything.) That leaves little room for religion.

And then of course there’s the nagging problem of consciousness. This is truly a God of the Gaps for Kripal (though he doesn’t push religion), for he takes science’s failure to explain the hard problem of consciousness to mean that science can never explain it, and that consciousness must therefore reflects some non-material phenomenon that will forever elude science:

In the rules of this materialist game, the scholar of religion can never take seriously what makes an experience or expression religious, since that would involve some truly fantastic vision of human nature and destiny, some transhuman divinization, some mental telegraphy, dreamlike soul, clairvoyant seer, or cosmic consciousness. All of that is taken off the table, in principle, as inappropriate to the academic project. And then we are told that there is nothing “religious” about religion, which, of course, is true, since we have just discounted all of that other stuff.

Actually, as I’ve pointed out many times, science does not take “nonmaterial” or spiritual phenomena off the table. It’s perfectly acceptable to test psychic and paranormal phenomena like ESP and spiritual healing, and, in fact, those tests have been done. But they always fail, and so, as Laplace said, we no longer need those explanations. It’s not that we’ve taken non-materialism off the table—it’s simply fallen off the table. Kripal then goes after consciousness as a material phenomenon:

. . . We are in the ridiculous situation of having conscious intellectuals tell us that consciousness does not really exist as such, that there is nothing to it except cognitive grids, software loops, and warm brain matter. If this were not so patently absurd and depressing, it would be funny.

Note the “as such” there. Nobody says that the phenomenon of consciousness doesn’t exist, merely that we don’t understand the evolutionary and neurological basis of how it works and how it came to be.  “As such” is a weasel phrase, meant to obscure the fact that we consider consciousness an “illusion” in the sense that, while it exists, it isn’t what it seems: it isn’t a little immaterial man sitting inside the brain and observing it all. It isn’t a disembodied “I.”

Then comes the whining about marginalization that inevitably accompanies this turf defense:

Humanists have paid a heavy price for their shrinking act. We are more or less ignored now by both the general public and our colleagues in the natural sciences, whose disciplines, of course, make no sense at all outside of universal observations, and who often work from bold cosmic visions, wildly counterintuitive models (think ghostlike multiverses and teleporting particles), and evolutionary spans of time that make our “histories” look insignificant and boring by comparison.

I am aware, of course, that there are signs of life in the humanities. I am thinking in particular of the development of “big history” in historiography and of the new materialisms, vitalisms, and panpsychisms of contemporary philosophy, as evident in Thomas Nagel’s recent well-publicized doubts about the adequacy of neo-Darwinian materialism, expressed in his book Mind and Cosmos.

Well Nagel’s book was well-publicized, but not well received. It was a work of philosophy of science, and was criticized heavily by both scientists and philosophers (see above). The people who liked Nagel’s message that There Is More Than Materialism were the theologians and the humanists who feel that science is stepping on their toes. I doubt that the “vitalisms and panpsychisms of contemporary philosophy” have gotten much traction beyond Nagel!

Kripal clearly shows an infection of God-of-the-Gapism, otherwise known as Paley’s Syndrome. Note his conclusion that what science hasn’t explained is what it cannot explain (my emphasis):

After all, consciousness is the fundamental ground of all that we know or ever will know. It is the ground of all of the sciences, all of the arts, all of the social sciences, all of the humanities, indeed all human knowledge and experience. Moreover, as far as we can tell, this presence is sui generis. It is its own thing. We know of nothing else like it in the universe, and anything we might know later we will know only through this same consciousness. Many want to claim the exact opposite, that consciousness is not its own thing, is reducible to warm, wet tissue and brainhood. But no one has come close to showing how that might work. Probably because it doesn’t.

Why is he so sure, given that many things that people once considered unexplainable have now been explained by science? What if we’re able to construct a computer or robot that is conscious? Why is Kripal so sure that’s impossible? I’ll tell you why: because he’s not only religious, but a humanities professor harboring great anxiety that science will shrink his kingdom.

Finally, Kripal uses David Eagleman’s example of a Bushman finding a transistor radio, and, fiddling with the wires, decides that the voices it emanates come from some of the circuits, because when those circuits are disconnected, the voices go away. (This reminds me of the paternalistic movie “The Gods Must be Crazy“, also involving the Bushmen—who, by the way, are usually called the San). How can that individual possibly imagine the presence of radio stations, distant cities, and civilizations? It is beyond his ken.

So, says Kripal, our consciousness is like that radio: it receives messages whose source is likewise beyond our ken. Those messages are “transhuman”: beyond the material domain—and sometimes coming from the dead.

William James, Henri Bergson, and Aldous Huxley all argued the same long before Eagleman. Bergson even used the same radio analogy. This is where the historian of religions—this one, anyway—steps in. There are, after all, countless other clues in the history of religions that rule the radio theory in, and that suggest, though hardly prove, that the human brain may function as a super-evolved neurological radio or television and, in rare but revealing moments when the channel suddenly “switches,” as an imperfect receiver of some transhuman signal that simply does not play by the rules as we know them.

[The radio model] puts back on the table much of the evidence that we have taken off as impossible or nonexistent (all that Platonic stuff about the human spirit). In this same generous, symmetrical spirit, it is not that materialism is wrong. It is that it is half-right.

Such a radio model certainly has no problem understanding how Mark Twain could have known about his brother’s imminent funeral, why a wife could know about her husband’s distant car wreck, or why a Swedish scientist could track a fire 50 miles away. The mind can know things distant in space and time because it is not limited to space or time. Mind is not “in” the radio or brain box. The payoff here is immense: The impossible suddenly becomes possible. Indeed, it becomes predictable.

What we have been doing for the past few centuries is studying the construction and workings of the physical radio. But the radio was built for the radio signal (and vice versa). How can we understand the one without the other? It is time to come to terms with both. It is time to invite Plato back to the table—to restore the humanities to consciousness. The rest will follow.

I am baffled why our lack of understanding of consciousness means that we will never be able to explain it in material terms. The whole history of science suggests otherwise. Most of us are now determinists about the brain: what feel like libertarian decisions made by a dualistic “ghost” in our brain are illusions: those “decisions” are made in our unconscious by factors we don’t understand. (I’m ignoring the argument about whether that determinism is compatible with any notion of “free will.”) New neurological experiments show that our decisions can be made some seconds before we’re conscious of having made them. Other experiments show that we can either impart a false sense of volition to people through psychological experiments, or remove a sense of volition even when subjects are behaving “willfully.”  Experiments on the brain show that we can affect human emotions or behavior through simple mechanical or chemical interventions.

In other words, the materialistic methods of science are slowly showing us that our sense of being “free agents” is an illusion. We do possess that sense, but we don’t have the ability to choose other than what we did. Our sense of dualistic free will is an illusion; it is a real sense, but it is not what it seems.

Why, then, should our sense of consciousness be otherwise? We’ve expelled the Ghost of Dualistic Will from science, and the Ghost of Consciousness is next in line.

I will believe Kripal’s adherence to “transhuman signals” when we’re able to confirm them as repeatable phenomena—after all, I don’t completely rule out the supernatural—rather than as erratic anecdotes.

What’s clear is that consciousness is the new creationism. Like creationism, it was once something explicable, at least to a certain mindset, only by invoking God  But all signs are that consciousness will go the way of creationism: a vestigial remnant of our religious past.

 

 

 

 

 

 

 

 

 

Family business: Daniel Matute wins Dobzhansky Prize, and Matthew’s cats

April 1, 2014 • 5:00 am

I’m very proud to report that my last student, Dr. Daniel Matute, has been awarded the Dobzhansky Prize from the Society of the Study of Evolution. The award and description of Daniel’s work is here.  The prize, which comes with a generous emolument, is perhaps the most prestigious award conferred on a beginning evolutionary biologist. In 2011 Daniel also won the University of Chicago prize for the best dissertation in the biological sciences. Here’s the description of the Dobzhansky Prize (Dobzhansky was my academic grandfather, the advisor of Dr. Richard Lewontin, my own advisor):

The Theodosius Dobzhansky Prize is awarded annually by the Society for the Study of Evolution to recognize the accomplishments and future promise of an outstanding young evolutionary biologist.   The prize was established in memory of Professor Dobzhansky by his friends and colleagues, and reflects his lifelong commitment to fostering the research careers of young scientists.

Daniel graduated from my lab in 2011 and has been doing a postdoc on Drosophila genetics and speciation in the laboratory of Dr. Molly Przeworski (also at the U of C) since then. He’ll be starting his first job this fall at the University of North Carolina at Chapel Hill.

Daniel’s work in the lab was on the genetics of reproductive isolation, of morphological differences between species, and on the phenomenon of “reinforcement” (the increase in reproductive isolation between species in areas where their ranges overlap). That work resulted in seven papers in major journals, including Cell, Evolution, Science, Current Biology and PLoS Genetics. It is a remarkable record of accomplishment.

A note of paternal pride: I’ve had only four students get their Ph.D.s in my lab, but two of them (the other was Allen Orr) have won this prize. And one of my other students, Mohamed Noor, is the President of the Society that will be giving Daniel his award at the annual meetings in Raleigh, North Carolina, this year. (Orr was also president of the SSE.) As my career winds down, I am satisfied that I have replaced myself several times over. What better legacy can a scientist have? Our own work and achievements stand out only briefly, the lower bricks in an ever-growing wall, but the wall is what’s important.

Here’s Daniel hard at work:

Daniel Matute

Here’s our “family tree” rooted at the great geneticist Thomas Hunt Morgan (click to enlarge). Kelly Dyer was not my student but my technician, but she’s now gone on to become a professor of genetics at the University of Georgia.  Audrey Chang left my lab before completing her degree, but eventually got her Ph.D. from Noor (it’s all very incestuous) and is now at the American Museum of Natural History.

And, because I don’t know where else to put this, here’s a picture that Matthew Cobb, frequent contributor to this site, sent me yesterday. It shows his cats, Ollie, and Pepper, and came with the note that they were enjoying the spring warmth, as well as this:

Their different gazes sum up their characters – Pepper is very laid back while Ollie (the nose-scratcher) is skittish. They found the door into summer! (Or spring, anyway)

“Nose scratcher” refers to the fact that when I first met Ollie, I held him up to my face to give him fusses, and he simply swiped at my nose with his paw, inflicting a copiously bleeding wound.

Spring boots

April 1, 2014 • 4:31 am

At last the weather is sufficiently decent, and reliable, that I can don my boots.

Here’s a fairly new pair made by the estimable outfit Tres Outlaws in El Paso, Texas.  They’re tall (14-inch shafts), with fancy burgundy stitching that matches the oxblood vamps.  Guess the hide (which isn’t hard), but then also guess which part of the animal they’re from:

A cat suckling ducklings!

March 31, 2014 • 2:17 pm

I believe I’ve put up a shorter version of this video before, but this is the full one, and much better. It’s about an Irish cat who actually nursed a brood of ducklings along with her kittens, and the ducklings actually drank the cat’s milk! That’s unbelievable.  And watch what happens when the “yellow kittens” get older, more rambunctious, and the mother tries to control them.

Yet more government support for creationism

March 31, 2014 • 11:43 am

by Greg Mayer

In a must-read special report at Politico, Stephanie Simon examines the growth of government-funded instruction in creationism via the voucher school movement.

Voucher schools are private schools for which the government pays full or partial tuition. Most of them are religious (70 %, fide Politico), are not held to educational standards, and have little oversight. Here’s the money quote:

Taxpayers in 14 states will bankroll nearly $1 billion this year in tuition for private schools, including hundreds of religious schools that teach Earth is less than 10,000 years old, Adam and Eve strolled the garden with dinosaurs, and much of modern biology, geology and cosmology is a web of lies.

Now a major push to expand these voucher programs is under way from Alaska to New York, a development that seems certain to sharply increase the investment.

Public debate about science education tends to center on bills like one in Missouri, which would allow public school parents to pull their kids from science class whenever the topic of evolution comes up. But the more striking shift in public policy has flown largely under the radar, as a well-funded political campaign has pushed to open the spigot for tax dollars to flow to private schools. Among them are Bible-based schools that train students to reject and rebut the cornerstones of modern science. [emphasis added]

Jerry recently highlighted a similar report by student pro-science advocate Zack Kopplin on government subsidy of creationism, and how this support is now found in many states. Simon shows how the movement for voucher schools is spreading over the country, spending lots of money (including from—you guessed it—the Koch brothers), and trying to influence both Republicans and Democrats.

One thing that struck me is that the curricula of these schools don’t just teach some sort of alternative set of claims about the world, but teach active hostility to science. An example from Simon’s piece:

 Another Calvary Christian Academy, this one in Fort Lauderdale, Fla., describes the goal of its AP Biology course as preparing “students to have faith in Jesus in an age of science by evaluating college-level biology, chemistry and physics from a purely biblical perspective.”

Their AP Biology class is designed not to prepare students for college work, but to resist doing college work!!

It’s also absolutely clear that these schools are misusing the appellation AP—Advanced Placement-—for their courses. Advanced Placement is a set of curricula and exams-for-credit in a wide variety of subjects developed by the College Board. For Biology, the very first item in the AP curriculum is

Big Idea 1: The process of evolution drives the diversity and unity of life.

And that’s exactly right: evolution is the central concept of biology, and the first thing students of biology should learn (see the full curricular outline here)!

That support for voucher schools invokes broader cultural themes than just anti-science is shown in the following passage from Simon’s report:

But Doug Tuthill, who runs one of the largest private school choice programs in the nation, says states have no right to determine what kids should learn, beyond basic math, reading and writing. Other topics, from the age of Earth to the reasons for the Civil War, are just too controversial for a government mandate, he said, even when taxpayer money is at stake.

This is anti-science, anti-government oversight, and even neo-Confederate: “the reasons for the Civil War”! (As made abundantly clear by the secession ordinances, which have been much republished with salutary effect in the last few years as part of the Civil War sesquicentennial observances, and as Apu memorably put it, “Slavery it is, sir.“) These broader cultural themes may explain the support of people like the Koch brothers, who, for all their faults, are not anti-evolution.

The report is accompanied by an astonishing set of images illustrating what passes for science in some of these schools.

A two-option multiple choice question– now that’s rigorous! And the “wrong choice” can be easily dismissed as not even making sense: are creationists being distinguished from clouds, because students in these schools can’t readily distinguish between people and meteorological phenomena? Even fifth graders know what rain is!

In one paragraph, the above slide combines  factual errors in geology and archaeology, a complete non sequitur conclusion, and tops it off with an error about the Bible. The writers of this curriculum aren’t even any good at Bible study, which is what they claim as their area of expertise.

Wisconsin Lutheran High School (from Politico)

I finish with the above because it comes from a school not very far from where I live and work. There are a cluster of tax-supported creationist schools in southeastern Wisconsin, as can be seen in this map from Slate. This image also shows that even so-called mainline churches like the Lutherans can be creationists. To be fair to Lutherans in general, though, I note that there’s a lot of variation among the varied Lutheran denominations; and, as Simon points out, not all religious schools are creationist (I received a fine science education during 12 years at Catholic schools, although this was before the Catholic hierarchy made a political alliance with right wing Protestantism).

My university, the University of Wisconsin-Parkside, was involved in getting this publicly-funded private school movement started  in southeastern Wisconsin a dozen years ago. The University was mandated by the state legislature to “charter” a school that would be tax-supported, but not subject to oversight by the local school district, nor, even much by the University, despite the fact that we had somehow officially given them the right to be a state-funded school. There was only one group wanting to start such a school (I guess they had friends in the legislature), and a university committee was convened that included a biology professor to organize the granting of the charter. Some way into the process I became aware that the principal of the new school was to be a local church pastor who was somewhat notorious for writing loony items on the opinion page in the local paper, including creationist material. I alerted the committee to this, but when the biologist on the committee brought it up, a charter school advocacy “consultant” to the committee firmly stated that such concerns about what the school would be teaching were off limits and not subject to discussion by the committee. The creationist principal did not last long, fortunately, and my understanding of the school is that it does not teach creationism.

The weirdest adaptation? The lizard that squirts blood from its eyes (with update)

March 31, 2014 • 9:56 am

by Matthew Cobb

A tw**t from the King of Gifs (pronounced…), @JohnRHutchison, containing a gif of a horned lizard squirting blood from its eyes. THIS IS REAL and is one of the most bizarre animal adaptations I can think of.

Here’s a National Geographic video that gives some more information. And yes it is blood. It’s not  squirted from the eyeball though. National Geographic says:

The ominous squirting blood emanates from ducts in the corners of their eyes and can travel a distance of up to three feet (one meter). It’s meant to confuse would-be predators, but also contains a chemical that is noxious to dogs, wolves, and coyotes.

Greg, the WEIT resident herpetologist, will probably know more about this odd phenomenon…

Can anyone think of a weirder adaptation?

UPDATE: It would appear that whatever the effect of the blood-spurting eyes on mammals, the American kestrel is unimpressed. This photo by John Roser shows over 30 horned lizard skulls that were found while clearing out a kestrel nestbox (h/t @ftcreature on Tw*tter)
