‘Magic, Illusions, and Zombies’: An Exchange between Daniel C. Dennett and Galen Strawson

Dan Dennett in the New York Review of Books:

75400I thank Galen Strawson for his passionate attack on my views, since it provides a large, clear target for my rebuttal. I would never have dared put Strawson’s words in the mouth of Otto (the fictional critic I invented as a sort of ombudsman for the skeptical reader of Consciousness Explained) for fear of being scolded for creating a strawman. A full-throated, table-thumping Strawson serves me much better. He clearly believes what he says, thinks it is very important, and is spectacularly wrong in useful ways. His most obvious mistake is his misrepresentation of my main claim:

If [Dennett] is right, no one has ever really suffered, in spite of agonizing diseases, mental illness, murder, rape, famine, slavery, bereavement, torture, and genocide. And no one has ever caused anyone else pain.

I don’t deny the existence of consciousness; of course, consciousness exists; it just isn’t what most people think it is, as I have said many times. I do grant that Strawson expresses quite vividly a widespread conviction about what consciousness is. Might people—and Strawson, in particular—be wrong about this? That is the issue.

He invokes common sense against which to contrast “the silliest claim ever made” (I’m honored!), but here is some other common sense that pushes back: when you encounter people who claim to have seen a magician saw a lady in half, counsel them to postpone their extravagant hypotheses—backwards time travel, multi-world wormholes, quantum entanglement, “real magic”—until they have exhausted the more mundane possibilities. Unrevolutionary science has discovered good explanations for such heretofore baffling phenomena as reproduction, metabolism, growth, and self-repair, for instance. So while it is possible that we will have to overthrow that science in order to account for consciousness, we should explore the default possibilities first.

Excerpts from Sean Penn’s book are here, and they are worse than can be imagined

Randall Colburn in The A. V. Club:

ScreenHunter_3026 Apr. 03 20.11“There is pride to be had where the prejudicial is practiced with precision in the trenchant triage of tactile terminations.”

No, this is not a tongue twister you’d hear muttered in the wings of a high school stage play. This is, no lie, just one of several deadening excerpts from Bob Honey Who Just Do Stuff, the debut novel of actor Sean Penn, who, terrifyingly, seems to be giving up acting in favor of poorly aping Thomas Pynchon and successfully embodying Charles Bukowski.

The 160-page novel tells the story of its namesake character, a septic tank entrepreneur and contract killer who Forrest Gumps his way through Hurricane Katrina, Baghdad at the outset of the Iraq War, and the “penis-edency” of a Donald Trumpian commander in chief. Huffington Post’s Claire Fallon describes it as “an exercise in ass-showing, a 160-page self-own.” Other reviews are kinder, if similarly unimpressed. The New York Times calls it “agonizing” and “conspicuously un-fun,” while Entertainment Weekly criticizes its “woozy gender politics” while dubbing it “shrill,” “confounding,” and “a little hypocritical.”

But one needn’t dig far to discover the dissertation’s most dunk-worthy declarations, which allow for an astonishing abundance of alliterative announcements.

What’s the Matter With Trumpland?

Paul Krugman in the New York Times:

Merlin_136168116_de53aaa1-4c0b-4c02-a013-926da89a818d-superJumboThese days almost everyone has the (justified) sense that America is coming apart at the seams. But this isn’t a new story, or just about politics. Things have been falling apart on multiple fronts since the 1970s: Political polarization has marched side by side with economic polarization, as income inequality has soared.

And both political and economic polarization have a strong geographic dimension. On the economic side, some parts of America, mainly big coastal cities, have been getting much richer, but other parts have been left behind. On the political side, the thriving regions by and large voted for Hillary Clinton, while the lagging regions voted for Donald Trump.

I’m not saying that everything is great in coastal cities: Many people remain economically stranded even within metropolitan areas that look successful in the aggregate. And soaring housing costs, thanks in large part to Nimbyism, are a real and growing problem. Still, regional economic divergence is real and correlates closely, though not perfectly, with political divergence.

But what’s behind this divergence? What’s the matter with Trumpland?

How We, The Indians, Came to Be

Tony Joseph in The Quint:

ScreenHunter_3025 Apr. 03 19.58Before you begin to read this, take a chair and sit down comfortably. Because this is going to take some time, and it is going to address some of the most fundamental questions about how we, the Indians, or South Asians more generally, came to be.

The answers you are going to read are taken from an extensive new study that has just been released, titled ‘The Genomic Formation of Central and South Asia’. It is co-authored by 92 scientists from around the world and was co-directed by Prof David Reich of Harvard Medical School. Reich runs a lab at Harvard that has no equal in its ability to sequence and analyse ancient DNA at scale and speed, and he has co-authored multiple studies in recent years that have changed the way we understand the prehistory of much of the world. His just-released book, ‘Who We Are and How We Got Here’, is currently making waves.

Among those 92 co-authors are scientists who are stars of an equal measure in their own disciplines, like James Mallory, archaeologist and author of the classic ‘In search of Indo-Europeans: Language, Archaeology and Myth’; and David Anthony, anthropologist and author of the ground-breaking ‘The Horse, The Wheel and the Language: How Bronze Age Raiders from the Eurasian Steppes Shaped the Modern World’.

Archaeobotanist Dorian Fuller and archaeologist Nicole Boivin are familiar names in India for the work they have done in the country.

Tuesday Poem

Tracks

Night, two o'clock: moonlight. The train has stopped
in the middle of the plain. Distance bright points of a town
twinkle cold on the horizon.

As when someone has gone into a dream so far
that he'll never remember he was there
when he come back to his room.

As when someone goes into a sickness so deep
that all his former days become twinkling points, a swarm,
cold and feeble on the horizon.

The train stand perfectly still.
Two o'clock: full moonlight, few stars.

How Joan Didion Became Joan Didion

Joan-didion-doc-3Michelle Dean at Buzzfeed News:

By the time Kazin’s profile was published, Didion was, quite simply, a star. But the Saturday Evening Post, the place that had let her write lyrically about migraines, about going home to Sacramento, or that flew her to Hawaii for a piece, had folded. She looked for other homes. Lifemagazine offered her a contract to write a column. But the relationship soured immediately; Didion asked to go to Saigon, because many writers—including Sontag and McCarthy—had already been there. Her editor demurred, telling her that “some of the guys are going out.” Her anger at this blithe dismissal turned into the now-famous column she wrote about visiting Hawaii during the prediction of a huge tidal wave:

My husband switches off the television set and stares out the window. I avoid his eyes, and brush the baby’s hair. In the absence of a natural disaster we are left again to our own uneasy devices. We are here on this island in the middle of the Pacific in lieu of filing for divorce.

This essay poses as self-revelation, but here the frame of marital trouble dissolves. Didion begins telling you instead how disconnected she had felt from everything, how difficult it was to feel. She confesses that she has become, as that old boyfriend predicted, someone who feels nothing. The piece is so relentlessly dark and despairing it is no wonder the Life editors were apparently startled by it. They gave it a title that reflected their bewilderment: “A Problem of Making Connections.”

the frankenstein problem

20180322_TNA54FohtbannerBrendan P. Foht at The New Atlantis:

There are few novels that have been more interpreted and re-­imagined than Frankenstein, and it has become something of a cliché in ­bioethics — especially in debates about embryo research and reproductive ­technologies — to invoke Victor Frankenstein’s hubris in “playing God” by creating a person out of inanimate matter. And yet, reading the story again two hundred years after its publication, we find that its moral teachings have been stubbornly ignored, or even inverted, by the scientists and ethicists who have the most to learn from it.

As a starting point for thinking about the counterintuitive place of the novel in contemporary discourse about technology and ethics, consider a 2012 essay by the French sociologist of science Bruno Latour, “Love Your Monsters,” in which he argues that the real lesson of the novel is that “we must care for our technologies as we do our children.” According to Latour, “Dr. Frankenstein’s crime was not that he invented a creature through some combination of hubris and high technology, but rather that he abandoned the creature to itself,” referring to the moment in the story when Frankenstein runs in horror, without good reason, from the creature he has made.

A Reckoning with Reality (TV)

Realitytv-1024x683Lucas Mann at The Paris Review:

When we were first getting into The Real Housewives of Beverly Hills, the husband of one of the show’s stars, who had seemed to be a real asshole (like potentially abusive) on-screen, hanged himself. The following season, his widow was back, shocked yet resilient, weepy but still game.

At the height of The Real Housewives of New Jersey (your favorite), Teresa went to jail for the mail, wire, and bank fraud that had funded the lifestyle she so proudly flaunted for the cameras. Her special return-home episode airs next month.

In the middle of our Here Comes Honey Boo Boo obsession, Honey Boo Boo’s mother’s boyfriend got arrested for rape, child molestation, aggravated child molestation, and aggravated sexual assault battery against Honey Boo Boo’s sister. The show got canceled, but Honey Boo Boo did appear in a special obesity episode of The Doctors, and now her mother is on Marriage Boot Camp.

To treat some diseases, researchers are putting immune cells on a diet

Mitch Leslie in Science:

Immune_socialAbout 12 years ago, Gary Glick and his wife noticed something wrong with their son, Jeremy. He seemed to be lagging behind his twin sister, recalls the immunologist and chemical biologist at the University of Michigan in Ann Arbor. "They were growing in unison, and he sort of stopped." Jeremy, who was 9 or 10 at the time, also looked sickly and pale and began complaining of nagging pains in his stomach and elsewhere. Rachel Lipson Glick, a physician, was stumped by their son's mysterious ailment. So were other doctors. It took about 3 years to rule out myriad cancers, endocrine malfunctions, and other potential causes and to determine that Jeremy had Crohn disease, an inflammation of the digestive tract stoked by misbehaving immune cells. The diagnosis made life harder for Jeremy, now 22 and a senior at college. To control the symptoms, he injects the antibody drug adalimumab (Humira). He will likely need it, or another immune-inhibiting treatment, for the rest of his life.

By coincidence, one of those alternatives might stem from his father's work. Gary Glick, like an increasing number of other researchers, is convinced that the immune cells driving conditions such as Crohn disease share a feature that could be their undoing: their metabolism. He has spent the past 2 decades searching for drugs that target metabolic adaptations of immune cells. Clinical trials by Lycera, a company Glick founded, are now assessing the first of those drugs for psoriasis and ulcerative colitis, an intestinal illness related to Crohn disease. Drug companies are working to develop other candidates. Researchers are also looking to deploy existing drugs that tamper with metabolism, such as the diabetes treatments metformin and 2-deoxyglucose (2DG). "It's a very exciting time," says immunologist Jonathan Powell of Johns Hopkins University's School of Medicine in Baltimore, Maryland. "Potentially, all immunologic diseases are targets for metabolic therapy."

Cancer researchers have also tried to disrupt cell metabolism, even testing some of the same drugs immunologists are investigating. But many scientists are convinced the strategy will work better for immune diseases than for tumors because drugs to treat those illnesses need only to suppress a relatively small number of overexuberant cells, not eliminate them.

Preston Brooks Canes the Union

by Michael Liss

Nypl.digitalcollections.6232540d-9d12-b4e8-e040-e00a18061bf0.001.w

History is fractal. Zoom out, and you see grand themes, mass movements, stirring oratory, and profound ideas. Zoom in, and it is countless individual acts and choices, smaller moments that often seem to be just footnotes, but are, on closer inspection, immensely revealing.

On May 22, 1856, South Carolina Congressman Preston Brooks entered the Senate Chamber, strode purposefully over to the desk of Massachusetts Senator Charles Sumner, and beat him senseless with a gold-headed, gutta-percha walking stick. So forceful, and so numerous were his blows, that Brooks shattered his weapon. And so much the damage done to his victim, both physical and psychological, that Sumner was unable to resume his Senatorial duties for nearly three years.

Matter of honor for Brooks. Sumner had just delivered a two-day jeremiad, “The Crime Against Kansas,” which was laced with insults against Brooks’ home state and his kin, South Carolina Senator Andrew Butler. As for the need for 30 swings of the cane on a bloodied, helpless victim, anyone who understood the profound passion of offended dignity of the Southern Gentleman could explain it. Who, of Brooks’ stature, wouldn’t have acted the same way when faced with the same provocation?

Brooks’ choice of a weapon said as much as his words. It was not an accident, not something grabbed in impulse. In the Southern Code, you dueled with an equal, but thrashed an inferior. Sumner, for all his refined manners, Harvard education, and the classical allusions in his speeches, was clearly a social inferior—a “Black Republican” of the worst type. Once Brooks settled on a course of action, he grappled with the choice of cane or bullwhip, but he never, ever, considered pistols.

Most of the South cheered. Fire-Eaters made similar threats against other Northern leaders, and Brooks mused, “It would not take much to have the throats of every Abolitionist cut.” He became a sort of a pop hero, the very exemplar of chivalrous Southern manliness. Among his adoring acolytes were students from the University of Virginia, who sent him a golden-headed cane, inscribed, and etched with the image of a cracked human skull.

Dance beyond words

by Dave Maier

Pina-movie-wallpaper-25338In 1985, by his own account, the filmmaker Wim Wenders had no interest in dance, and had to be dragged to a performance of choreographer Pina Bausch’s Café Müller by his companion, actress Solveig Dommartin (you remember her, she’s in Wings of Desire). However, he found himself so moved by the performance that he wept. So reports Siri Hustvedt in an essay accompanying the Criterion Collection issue of Wenders’s film tribute to Bausch, Pina: dance, dance, otherwise we are lost. With respect to Café Müller in particular, Hustvedt tells us that “one cannot encapsulate what one has seen in words.” That is, “one does not come away with a message or story that can be explicated […] Rather, [Bausch’s] work generates multiple, and often ambiguous, meanings,” which helps account for the work’s power:

The viewer’s emotion is born of a profound recognition of himself in the story that is being played out onstage before him. He engages in a participatory, embodied mirroring reaction with the dancers, which evades articulation in language. Susanne K. Langer is writing about music in the following passage from Philosophy in a New Key, but her commentary can be applied equally well to dance: “The real power of music lies in the fact that it can be ‘true’ to the life of feeling in a way that language cannot; for its significant forms have that ambivalence of content that words cannot have.” Musical meanings arrive, as Langer puts it, “below the threshold of consciousness, certainly outside the pale of discursive thinking. […] [Bausch:] “For I always know what I am looking for, but I know it with my intuition and not with my head.” Indeed, many artists work this way, even artists whose medium is words. There is always a preverbal, physiological, rhythmic, motoric, ground that precedes language and informs it.

Okay, that’s quite a mouthful. Let’s unpack it (as my anthropology teacher used to say).

If the experience of Café Müller reaches “beyond language,” a natural question is: what is it about dance, a non-verbal art, that allows it to do what words cannot? Is it that it is physical/gestural rather than verbal, or instead that it is characteristically artistic experience rather than everyday discourse? To answer this, we must also consider for comparison the two other possibilities: non-verbal non-art and verbal art (literature/poetry).

If everyday non-artistic gestures reach “beyond language” simply by being non-verbal, then it is hardly remarkable to say of dance that it does this as well, and thus it cannot be this mere ability that makes possible the latter’s power. It must be that what does the trick instead is that dance is an art of gesture, that it takes advantage of its non-verbal nature in a way that everyday gestures do not, in order to allow the exceptional experience that moved Wenders to tears. But what does that difference amount to here?

I’m a Lot Like Donald Trump

by Akim Reinhardt

Diet cokeThere are, of course, many ways in which I am nothing like Donald Trump. I do not publicly berate subordinates. I never drink Diet Coke. I am not a piece of human filth. I have not run for president, especially in a state of gross unpreparedness and unqualification.

But it should go without saying that any decent human being is, in many ways, not much like Donald Trump. Indeed, it is so obvious, that to even mention one's dissimilarities from The Donald is not only unenlightening but likely self-serving.

Much more interesting, I believe, is to consider the ways in which you really are quite similar to someone you find repugnant, to someone who is broken beyond repair, to someone you have absolutely no respect for whatsoever. Because when you acknowledge those features you hold in common with a disgusting, heinous wretch who fouls the earth with his very existence, then you can begin to penetrate your most obscure attributes, peel back your complex layers, and really learn something about yourself.

A well examined life cannot be lived amid self-congratulation or comfort. We can only discover our true selves by embarking upon difficult journeys to our inner souls and by confronting our deepest unpleasantries. Be happy and modest about any common ground you may stand upon with the hero. But know thyself when you turn to the mirror and chance upon fleeting glimpses of the villain. It is in that spirit of deep self-scrutiny that I must confess: I'm a lot like Donald Trump. Let me count the ways.

Digital remembrance of things past

by Sarah Firisen

ConnieMy grandmother had 7 sisters (and a couple of brothers who died young and none of us remember), my great-grandmother had 10 siblings. This past week, I attended reunions with 22 of the descendents of these ancestors, on two continents (New York and London). At these joyful family gatherings we told stories, reminisced about family craziness and shared old photos that we had all brought to lunch. Most of my second cousins have managed to find their grandmothers’ wedding photos and have posted them on our Facebook group and we’ve all been trying to identify which young bridesmaids were which sister. We’ve dug out photos of bar mitzvahs and weddings. We’ve worked collectively to put names to faces. It’s been great. But it occurs to me that my great grandchildren won’t get to do much of this. They’ll get to do other things, things that I can’t even imagine technology will enable, but not this. I have photo albums from when I was a kid and a wedding album. And my kids have some photos from when they were young, before smartphones and Facebook became so ubiquitous. But except for photos that I intend to frame and display, I haven’t had a photo printed for at least 10 years. And my children don’t even know how to get a photo printed (that’s not strictly true, my 17 year old took a photography class and knows how to use a darkroom, but I’m sure has no idea how to use Shutterfly because the idea of printing out a photo rather than posting it on Instagram is alien to her).

In response to my last piece on 3QD, a colleague, Josh, wrote the following thoughts to me: “Roots. Are at our very core. We can live without them for short periods, but to have soul, you have to listen to a record, not just hear an iphone stream, you have to turn the page of a book, not just flip an ipad, you have to hold the tattered edges of an old family picture and see the soul in their eyes to grab the essence of time capture. “

Increasingly, we don’t have photos to become tattered, new books to become dogeared, let alone records. Is my colleague Josh right, are we losing our roots and our souls? Something that is easy to forget is that many people would have said this when the phonograph was first introduced, or the first cameras. There have always been luddites, sometimes with legitimate concerns about technology, sometimes with just fears of the new. There have always been people worried that new technology will change fundamental things about who we are as people and how we interact with each other, and believe that those changes will only be negative. I don’t think the question is, “will we grow different roots with digital photos”, but rather, why is it that these “roots” are necessarily inferior? The albums that I scoured for photos yesterday were buried in a box in the back of a closet. I haven’t looked at any of them in years. My children don’t even realize I have most of these photos. But in our digital, social media lives, we’re sharing our photos all the time. One of my more favorite Facebook features is when it shows you photos of this day on x year and it shows me some adorable photo of my kids when they were little or reminds me of a great trip I was on. Often, I repost these photos and tag my kids. I know that some people will say that most of us overshare, and perhaps we do, but, just as with my cousins’ sharing of photos of our grandmothers on Facebook, this kind of sharing can do its part to fortify relationship bonds. Years ago, I would have brought those photos to lunch, everyone would have passed them around and that would have been it. Now, I’ve digitized them, posted them on our Facebook group and we have online discussions about them including in cousins who weren’t able to attend the reunions, we give these photos a life beyond a dusty photo album in the back of a closet.

Leapin’ Lizards: Three Lessons I Learned in Marching Band

by Bill Benzon

Girl marchingLike many musicians, I was in a marching band in middle school and high school, the Marching Rams of Richland Township in Western Pennsylvania. We were a very good band. We marched in the Cherry Blossom Festival in Washington, D.C. in 1965.

That experience was a rich one. But it was also complicated and fraught with anxiety and ambivalence.

These lessons are about the lizard brain and its problematic relationship with civilization. Not merely Western Civ, mind you, but any civilization whatsoever.

Lesson the First: It’s the Groove, Baby

Those aren’t the words he used, but that’s what he meant. It’s the groove that tells the story; it’s the groove that moves the feet.

I’m talking about something told to me, though not to me personally, by Richard Cuppett, director of my high school marching band. Cuppett was something of a taskmaster and worked us hard. Because he did so, the band was an excellent one, so good, rumor had it, that some people came to football games—we’re talking Steeler country, folks, the coal mines and steel mills that fed the fans of the Pittsburgh Steelers—as much to see the band as to watch the football game.

Cuppett was talking to the band about excellence. How can you tell that a band is really good? If kids march alongside the band when it is on parade, the band is a good one. He passed that on to us as a lesson, though I forget whom he attributed it to. Perhaps some bandleader he’d worked with, or perhaps some legendary figure, like John Philips Sousa.

It sounded strange when I first heard it, gathered there in the band room along with the other bandsmen. It didn’t quite make sense to let little kids be the judges of band quality. But Cuppett was the director, so it must be true—I was just a kid then, and so inclined to believe things told to me by someone in authority.

His point, of course, is that when music is really grooving, it’s infectious. It will attract those little kids and get their fidgety feed to move in time with the music. For that to happen, two things are necessary: the musicians have to play together, and they have to play with passion. Not just one, or the other, but both at the same time.

Everyone, together, passion.

Can There Be an Atheist Novel?

M. M. Owen in The Point:

ScreenHunter_3023 Apr. 01 21.29The Hungarian philosopher György Lukács called the novel “the epic of a world that has been abandoned by God.” Other forces played more obviously into the form’s rise to literary preeminence—the consolidation of a middle class; advances in printing technology—but the link between the emergence of the novel and the decline of religiosity is strong. Three hundred years ago, reading novels (as opposed to the classics, or Shakespeare) was widely seen as vulgar, indicative of a deficient mind. So was not believing in a divine creator. Today, at least among the sort of people who tend to read literary magazines, both these thing are more likely to be regarded as signs of intellectual and moral refinement. For the critic James Wood, this is no coincidence: the novel is “the slayer of religions,” a form that swept away Biblical certitudes and replaced them with fictional narratives that move “in the shadow of doubt,” asking readers for a belief that is fundamentally and irreligiously metaphorical.

One author who would agree wholeheartedly with Wood is England’s Ian McEwan, who asserted in 2013 that the novel is a product of the Enlightenment that “has always been a secular and skeptical form.” McEwan is a committed nonbeliever, so committed that he qualifies as a junior member of the intellectual movement-cum-publishing-ploy known as New Atheism, which emerged in the wake of 9/11. Christopher Hitchens dedicated his God Is Not Great to McEwan, and McEwan blurbed Richard Dawkins’s The God Delusion, calling it “lucid and wise, truly magisterial.” The critics Arthur Bradley and Andrew Tate, in their 2010 study The New Atheist Novel, write of McEwan “it is tempting to say that—if his fiction did not exist—Dawkins and company would have had to invent it, so completely does it vindicate their worldview.” McEwan’s protagonists are universally, as Edward says in On Chesil Beach, “grateful to live in a time when religion has generally faded into insignificance.” Ostensibly, this view is never seriously challenged, the gratitude never corroded.

15 Years. More Than 1 Million Dead. No One Held Responsible.

Charles P. Pierce in Esquire:

Wbush-1521657377The most tragic and infuriating piece of writing of the week came in Tuesday’s New York Times. It carried a very plain and simple headline.

"Fifteen Years Ago, America Destroyed My Country"

My short visit only confirmed my conviction and fear that the invasion would spell disaster for Iraqis. Removing Saddam was just a byproduct of another objective: dismantling the Iraqi state and its institutions. That state was replaced with a dysfunctional and corrupt semi-state. We were still filming in Baghdad when L. Paul Bremer III, the head of the Coalition Provisional Authority, announced the formation of the so-called Governing Council in July 2003. The names of its members were each followed by their sect and ethnicity. Many of the Iraqis we spoke to on that day were upset with institutionalization of an ethno-sectarian quota system. Ethnic and sectarian tensions already existed, but their translation into political currency was toxic. Those unsavory characters on the governing council, most of whom were allies of the United States from the preceding decade, went on to loot the country, making it one of the most corrupt in the world.

Except for Sinan Antoon’s richly deserved jeremiad, the 15th anniversary of the worst foreign policy disaster in modern American history went sailing by largely unremarked, at least in this country. After all, over here, everyone was too busy keeping track of the latest news involving the vulgar talking yam the country had installed as president, how he was still truckling to Russian oligarchs, how he was still being run to ground by Bob Mueller, and about how he was being outwitted and out-lawyered by a lady from the adult entertainment industry.

How to Talk About ‘Race’ and Genetics

David Reich in the New York Times:

Merlin_136197381_37695f37-bb22-4428-afd6-9c89b0b28394-superJumboIn a Sunday Review essay last weekend, David Reich, a geneticist at Harvard, argued that science is changing how we think about “race” and urged a candid discussion of the findings, whatever they may be. Hundreds of readers left comments, many expressing worry about the possibility that the results could be misinterpreted or nefariously applied. Here are Dr. Reich’s responses to some of the comments. — The Editors

Unfortunately, science has always been misused. From slavery, to eugenics, to economic Darwinism, to anti-abortion politics, the latest scientific knowledge has been employed in the service of evil. The idea of forestalling such efforts is valiant but fruitless. Science must continue its pursuit of truth, and scientists, as always, must speak out when their discoveries are exploited for harmful purposes. — Syfredrick, Providence, R.I.

We scientists always need to keep in mind our social responsibilities and to think about whether what we are doing has positive or negative effects on our world.

With respect to today’s study of human variation, I am optimistic — I believe that it has been socially positive. It is making every racist view of the world untenable. In my just-published book, I explain how the ancient DNA revolution — which has provided far greater power to reveal what happened in our deep past than what was available before — has done far more to undermine racist beliefs than to support them. As I wrote in the final paragraph of my book:

The study of human variation has not always been a force for good. In Nazi Germany, someone with my expertise at interpreting genetic data would have been tasked with categorizing people by ancestry had that been possible with the science of the 1930s. But in our time, the findings from ancient DNA leave little solace for racist or nationalistic misinterpretation. In this field, the pursuit of truth for its own sake has overwhelmingly had the effect of exploding stereotypes, undercutting prejudice, and highlighting the connections among peoples not previously known to be related. I am optimistic that the direction of my work and that of my colleagues is to promote understanding, and I welcome our opportunity to do our best by the people, ancient and modern, whom we have been given the privilege to study.

My book also gives concrete examples of how it is no longer so easy to twist science to support long-cherished stereotypes because ancient DNA is now debunking the stories that used to be made up about the nature of human variation.

ENERGY RETURN ON ENERGY INVESTED

Matt Ridley in his blog:

Methode%2Ftimes%2Fprod%2Fweb%2Fbin%2F17922316-2ad6-11e8-908b-95a753c47952The modern world stands on a cairn built by energy conversions in the past. Just as it took many loaves of bread and nosebags of hay to build Salisbury Cathedral, so it took many cubic metres of gas or puffs of wind to power the computer and develop the software on which I write these words. The Industrial Revolution was founded on the discovery of how to convert heat into work, initially via steam. Before that, heat (wood, coal) and work (oxen, people, wind, water) were separate worlds.

To be valuable, any conversion technology must produce reliable, just-in-time power that greatly exceeds — by a factor of seven and upwards — the amount of energy that goes into its extraction, conversion and delivery to a consumer. It is this measure of productivity, EROEI (energy return on energy invested), that limits our choice.

You could make your own electricity on an exercise bicycle, eating organic ice cream as fuel, but such a system would have wildly negative EROEI once you include the energetics of farming cattle and making ice cream. It would also produce a pathetic trickle of power: about 50 watts (joules per second). The average Briton uses about 4,000 watts, as much energy as if she had 240 slaves on exercise bicycles in the back room, pedalling eight-hour shifts. That’s roughly what “civilisation” looked like in ancient Egypt or China.
