Octopus Arms Are Capable of Making Decisions Without Input From Their Brains

Michelle Starr in Science Alert:

With the ability to use tools, solve complex puzzles, and even play tricks on humans just for funsies, octopuses are fiercely smart. But their intelligence is quite weirdly built, since the eight-armed cephalopods have evolved differently from pretty much every other type of organism on Earth.

Rather than a centralised nervous system such as vertebrates have, two-thirds of an octopus’s neurons are spread throughout its body, distributed between its arms. And now scientists have determined that those neurons can make decisions without input from the brain.

What deterrence looks like

Kenan Malik in Pandaemonium:

The photos of Óscar and Valeria Ramírez, migrants from El Salvador, drowned in the Rio Grande as they tried to cross into the USA, are haunting and distressing, and have sparked outrage and anger in America. Four years ago, images of the Syrian toddler Alan Kurdi washed up on a Turkish beach similarly shocked and horrified Europe.

These deaths are neither accidents nor isolated cases. They are the consequences of immigration policy, on both sides of the Atlantic, that aims at ‘deterring’ migrants. A little boy lying dead on a beach, a father and daughter face down in a river – that is what deterrence looks like.

At least 175 people, including 13 children, have died on the US-Mexican border this year alone. More than 2000 have died over the past 5 years. The European figures are more startling still. Almost 600 people have drowned in the Mediterranean so far this year. Since 1993, some 35,000 have died. Thousands more, perhaps tens of thousands more, will have perished in silence, their deaths never recorded. Alan Kurdi and Óscar and Valeria Ramírez are merely the cases in which the imagery was shocking enough to have caught public attention.

Immigration controls today mean not simply a border guard asking you for your papers. They constitute a violent, coercive, militarised system of control. When a journalist from Der Speigel magazine visited the control room of Frontex, the EU’s border agency, he observed that the language used was that of ‘defending Europe against an enemy’.

Keith Haring’s urgent optimism: The genius of the New York street artist, whose star burned fast and acid bright

Thomas Calvocoressi in New Statesman:

March 2019: a woman is standing in front of some Swatch watches on a daytime TV antiques show. The presenter asks which is her favourite. “Probably this one,” she answers, pointing to a watch adorned with a cartoon barking mutt. “I just like the dog – it makes me smile.” The story of how Keith Haring’s symbols became so ubiquitous that they ended up on the wrists of Middle England as much as on the bedroom walls of 1980s Aids activists is both the contradiction and the genius of the New York street artist, whose star burned fast and acid bright. Tate Liverpool’s superb retrospective traces Haring’s ten-year flight from street artist to global consumer brand, from scrawling on the subway to painting the Berlin Wall, and details the turbulent political backdrop behind his work. We know many of his motifs well – the dog, the crawling baby, the three-eyed face – his thick black lines and dancing figures, but there’s nothing superficial about these deceptively simple scrawls.

They’re angry, anguished and urgent, as well as being joyous and optimistic. Apartheid, homophobia, HIV; hedonism, sexual liberation and the power of love. His influences range across cartoons, hip hop, video games, Egyptian hieroglyphics, Japanese calligraphy and Art Brut. Above all they fizz with a relentless energy; the feeling that Haring is in a (very real) race against time to cover every surface.

Having moved from small-town Pennsylvania to New York in 1978 to go to art college, he began honing an artistic language that used symbols to express his social message. The subway became his canvas. While other graffiti artists were spraying paint on walls, Haring chose white chalk for his strikingly effective sketches, like post-industrial cave paintings, allowing him to reach the largest and most diverse possible audience. And they were certainly noticed. Videos showing commuters’ reactions to his guerrilla art are amusing to watch: some disapproving, others enthralled. What is striking is the grimness of the setting: early-1980s New York was hollowed out, depressed and bankrupt. In contrast, Haring’s work is overwhelmingly positive – a gift to the public. Alongside the pulsating bodies and TVs, the robots and breakdancers, come cheering messages: “New Year ’84”, “Happy Valentine’s”, “Still alive in ’85”.

Sunday Poem

Zen of Housework

I look over my own shoulder
down my arms
to where they disappear under water
into hands inside pink rubber gloves
moiling among dinner dishes.

My hands lift a wine glass,
holding it by the stem and under the bowl.
It breaks the surface
like a chalice
rising from a medieval lake.

Full of the grey wine
of domesticity, the glass floats
to the level of my eyes.
Behind it, through the window
above the sink, the sun, among
a ceremony of sparrows and bare branches,
is setting in Western America.

I can see thousands of droplets
of steam—each a tiny spectrum—rising
from my goblet of grey wine.
They sway, changing directions
constantly—like a school of playful fish,
or like the sheer curtain
on the window to another world.

Ah, grey sacrament of the mundane!

Scientists Are Giving Dead Brains New Life. What Could Go Wrong?

Matthew Shaer in The New York Times:

A few years ago, a scientist named Nenad Sestan began throwing around an idea for an experiment so obviously insane, so “wild” and “totally out there,” as he put it to me recently, that at first he told almost no one about it: not his wife or kids, not his bosses in Yale’s neuroscience department, not the dean of the university’s medical school. Like everything Sestan studies, the idea centered on the mammalian brain. More specific, it centered on the tree-shaped neurons that govern speech, motor function and thought — the cells, in short, that make us who we are. In the course of his research, Sestan, an expert in developmental neurobiology, regularly ordered slices of animal and human brain tissue from various brain banks, which shipped the specimens to Yale in coolers full of ice. Sometimes the tissue arrived within three or four hours of the donor’s death. Sometimes it took more than a day. Still, Sestan and his team were able to culture, or grow, active cells from that tissue — tissue that was, for all practical purposes, entirely dead. In the right circumstances, they could actually keep the cells alive for several weeks at a stretch.

When I met with Sestan this spring, at his lab in New Haven, he took great care to stress that he was far from the only scientist to have noticed the phenomenon. “Lots of people knew this,” he said. “Lots and lots.” And yet he seems to have been one of the few to take these findings and push them forward: If you could restore activity to individual post-mortem brain cells, he reasoned to himself, what was to stop you from restoring activity to entire slices of post-mortem brain?

To do so would be to create an entirely novel medium for understanding brain function. “One of the things we studied in our lab was the connectome — a kind of wiring map of the brain,” Sestan told me. Research on the connectome, which comprises the brain’s 90 billion neurons and hundreds of trillions of synapses, is widely viewed among neuroscientists as integral to understanding — and potentially treating — a range of disorders, from autism to schizophrenia. And yet there are few reliable ways of tracing all those connections in the brains of large mammals. “I thought, O.K., let’s see if this” — slices of cellularly revived brain tissue — “is the way to go,” Sestan said.

Hobsbawm, Unrepentant

Leonard Benardo in The American Progress:

When I was in graduate school, I had the good fortune to hear Eric Hobsbawm lecture on nationalism. The year was 1992. Hobsbawm had just published his widely read and sharply debated book on the theme, and in the aftermath of the implosion in communist Central and Eastern Europe and the revival of the so-called captive nations, everyone wanted to hear his take on the subject. Hobsbawm’s talk was packed. Edward Said, the esteemed Columbia University professor of literature, arrived late and found a spot only on the floor in the back. With Hobsbawm at perhaps his reputational apogee, the event felt more like an Event, a happening of unusual significance.

Richard Evans’s appreciative and deeply researched biography of the Marxist historian and intellectual, only a handful of years since Hobsbawm’s passing, is an event in itself. Clocking in at nearly 800 pages, it is an imposing summation and a contribution to a boutique subgenre: historical biography of major historians by practicing historians.

In a university age where disciplines punish scholars for moving off-script, Hobsbawm was an old-fashioned person of letters. Trained in Cambridge, Hobsbawm ranged far and wide, disallowing the strictures of disciplinary pressure to confine his intellectual reach. No subject was too remote, no idea un-germane. Devoted to a general approach that prized economic explanation, it was never an economics at the expense of culture, politics, or ideology, even if the economic “base” generally would have primacy. There was a logic to history for Hobsbawm, a materialist logic, yet contingency was never sacrificed at its altar.

Alan Brinkley’s Visions of Liberalism

Eric Foner in The Nation:

Alan Brinkley, who died on June 16 at the age of 70, was one of the most influential historians of his generation and a public intellectual whose writings helped to shape our understanding of modern American politics. His books are models of historical scholarship, written in a wonderfully accessible style. And, to employ a much-abused word, they are remarkably relevant. His central preoccupations—the strengths, limits, and vulnerabilities of the 20th-century American liberal tradition; the challenges to it, both internal and external; the connections between popular movements and political leadership; and the enduring legacies of the New Deal—are at the center of debate today.

The son of the prominent television newscaster David Brinkley, Alan Brinkley grew up in Washington in a household immersed in national politics. His first book, Voices of Protest, examined the 1930s careers of the popular demagogues Huey Long and Father Charles E. Coughlin. A winner of the National Book Award, it reflected his enduring interest in how modern communications media—in the case of Long and Coughlin, the radio—revolutionized the circulation of political ideas. He returned to this theme in his biography of Henry Luce, the founder of TimeLife, and other mass-circulation magazines.

In The End of Reform, Brinkley offered a pioneering account of how New Deal liberalism shifted in the late 1930s from a commitment to regulating and restructuring modern capitalism to acceptance of the corporate economy coupled with the hope that the fruits of economic growth stimulated by government spending would be widely shared.

Reading Like a Citizen

Lida Maxwell in the LA Review of Books:

IN ANNA BURNS’S Man Booker Prize–winning novel, Milkman, the main character — “middle sister” — learns about two-thirds of the way through the book that she has been defined as a “beyond-the-pale” in her community. This status comes not as a result of her attempts to avoid the sexual stalking of a local paramilitary leader (“Milkman”), but instead as a result of her habit of walking while reading. “Longest friend” tells her that her behavior is “not natural”; it is “disturbing,” “deviant,” “[n]ot public-spirited,” “[n]ot self-preservation.” Walking while reading, her friend tells her, is an activity that is “incapable of being mentally grasped, of being understood.” She is “[going] around in a political scene” with her “head switched off.”

Of course, middle sister’s head is very much switched on, but not in the way her community demands. Rather than using her head to defer to what Astra Taylor calls “constraining common sense,” middle sister goes about in public letting her body and mind inform each other, opening up new possibilities for thought and movement.

Burns’s book is my example, not Taylor’s, but “walking while reading” is as good a description as any for the kind of democratic citizenship Taylor advocates in her magnificent, paradigm-shifting new book, Democracy May Not Exist, but We’ll Miss It When It’s Gone. Taylor’s book challenges the very old idea that the demos is the “belly” of the polity, which depends on the “head” of elites to direct and guide it.

“The Liberal Idea Has Become Obsolete” Putin, Geuss and Habermas

Martin Jay in The Point:

There is, in other words, a certain amount of bad faith in Geuss’s arguing against argumentation, giving reasons against the power of reasoning. But the performative contradiction reproach, let it be admitted, only goes so far in rebutting Geuss’s disillusioned take on the role of communicative rationality in the public sphere. It smacks too much of a clever schoolboy trick to stifle a discussion before it can begin. Geuss’s case should be addressed on its own merits, taking his points, both empirical and theoretical, at their strongest. Otherwise, the defender of communicative rationality will be open to the charge of performative contradiction in turn.

Let me begin by conceding that the current political discourse in liberal democracies—Geuss’s main case is the cacophonous Brexit debate, but it would be easy to give other examples on both sides of the Atlantic—provides ample evidence that we are a long way in practice from Habermas’s ideal speech situation. Of course, he always posited it as a counterfactual, which could only be approached asymptotically with no guarantee that we are going in the right direction. Like the democracy that is always “to come,” as Derrideans are wont to say, or “the perfect union” that is always a task, not an accomplished state of affairs, it is an aspirational goal. By making the obvious point that we have not yet achieved it, does it follow that its function as such a goal is negated? Geuss is thus setting up a straw man in asserting that “no amount of exertion will suffice to permit us to establish within the domain of the natural phenomenon ‘communication’ a safe-zone that is actually completely protected on all sides from the possible use of force.” Would the same disconnect between imperfect achievement and enduring aspiration also render otiose other such laudable goals as, say, equality, dignity, autonomy or abundance for all?

A ‘Theory of Everything’?

Manjit Kumar at The Guardian:

Unsurprisingly from the author of The Strangest Man, an award-winning biography of Dirac, Farmelo has offered a thoughtful, well-informed reply to those who believe the quest for mathematical beauty has led theoretical physicists into adopting sterile, ultra-mathematical approaches divorced from reality. He makes a persuasive case as he argues that theorists have not spent the last 40 years wasting their time writing quasi-scientific fairytales and that many of the ideas and concepts that have emerged will endure.

Most of this is not conventional science, Farmelo admits. Rather, it is speculative science. But it is science nonetheless because it’s rooted in the two great theories of the 20th century: quantum mechanics and relativity. At the heart of this book is an account of how physics has stimulated mathematical breakthroughs and maths has led to advances in physics.

Walter Bagehot and the ‘Age of Discussion’

Michael Dirda at The Washington Post:

Walter Bagehot — pronounced Badge-it — was first called “the greatest Victorian” by that capaciously learned historian of 19th-century England, G.M. Young. The phrase has been attached to Bagehot’s name ever since and is again used by James Grant in the subtitle of this new biography, even though it would be more accurate to call its subject “the most versatile Victorian.”

Born the son of a country banker, Bagehot (1826-1877) attended University College London, where he received the gold medal for outstanding work in intellectual and moral philosophy. Soon after, he joined his father at Stuckey’s Bank, where he eventually became one of its directors. Seemingly tireless, young Walter simultaneously established himself as a journalist, initially making his name with irreverent essays about Shakespeare, Dickens and other canonical figures of English literature and history but eventually specializing in critical articles about economic and financial subjects.

The Art of the Swimming Pool

James Delbourgo at Literary Review:

By suspending the normal rules of earth-bound weight and motion, swimming pools bend certain rules of mental operation too, presenting possibilities for divine transformation and fatal transgression. Their creative potential often takes perverse and sometimes cruel forms. A Barbara Laing photograph from 1991 features a mule falling through the air towards a tank of water during ‘The World’s Only High-Diving Mules Show’ at the New Mexico State Fair in Albuquerque. Penned into a grandstand and shading their brows, fairgoers watch expectantly. One marvels at the bizarre freak-show machinations that brought this animal to its improbable plunge.

All swimming pools, however, deal in the unnatural. Southern California is the modern heartland of this glorious folly. Roman Polanski’s Chinatown (1974), in which the diversion of water away from Owens valley to Los Angeles is likened to an incestuous act of rape, still resonates.

Sanam Maher: on the trail of murdered Pakistani social media star Qandeel Baloch

Rachel Cooke in The Guardian:

It takes a little over two hours to drive from Multan, a city in southern Punjab, Pakistan, to the village of Shah Sadar Din, and the first time the journalist Sanam Maher made the journey, her eyes widened at every turn. In Dera Ghazi Khan, a town close to the village, none of the faces of the women she saw on the streets were visible. Some wore what looked like black ski masks with slits for their eyes. Others were covered by burqas with no eye-slits at all and so extensive that she felt half naked under her own dupatta (scarf). A thin funnel rises from the top of this kind of burqa: a device to allow air inside so that the wearer does not suffocate. Her contact in the town, noticing her staring, mentioned a place not far away, where the tribal belt of Balochistan province starts: the women there, he told her, were not given shoes. She was confused. Why not? “You’ll never look at any man if you’re scared of where your naked foot might fall when you leave your home,” he replied impatiently, as if it was the most obvious thing in the world.

Maher, who is based in Karachi, was in Shah Sadar Din to investigate the life and death of Fouzia Azeem, AKA Qandeel Baloch, Pakistan’s first social media celebrity and the woman some like to describe as its Kim Kardashian. Baloch was born here, the daughter of a poor family, and when she was murdered on 15 July, 2016, her body was supposed to end up in the village’s brown river, a spot well known for being the final resting place of women who have died at the hands of their relatives in so-called “honour” killings. On the day in question, however, there were too many people around to manage this (another villager had died; crowds of mourners were gathering). Baloch’s mother found the body at home; her father informed the authorities. When the police arrived, Baloch was still lying where she had been drugged and asphyxiated, in a bedroom at the small house that she rented for her parents in Multan. She was just 26.

“Visiting Shah Sadar Din was a huge culture shock for me,” says Maher, whose book about the case, A Woman Like Her, is published in the UK next month (it has already caused something of a sensation in south Asia). “The women were so completely covered: I’d never seen that anywhere that I’d lived or worked. But it’s important to say straight off that, though this is typical of south Punjab, it has nothing at all to do with religion. These [dress codes] are cultural diktats, just as honour killing and other forms of violence against women are cultural diktats. This is men wanting to control how the women around them live.”

Neal Stephenson’s New Novel — Part Tech, Part Fantasy — Dazzles

Charles Yu in The New York Times:

Straw poll: Who thinks we’re living in the Matrix?

On the one hand, are we really to believe a single human is responsible for the body of work — entertaining, brilliant, immense — that Neal Stephenson has produced over the past quarter-century? Turning out thousand-page novels every couple of years? It seems much more likely that a computer is behind all of this. On the other hand, have you read Neal Stephenson? His mind is capable of going places no one else has ever imagined, let alone rendered in photorealist prose. And he doesn’t just go to those places; he takes us with him. The very fact of Stephenson’s existence might be the best argument we have against the simulation hypothesis. His latest, “Fall; or, Dodge in Hell,” is another piece of evidence in the anti-Matrix case: a staggering feat of imagination, intelligence and stamina. For long stretches, at least. Between those long stretches, there are sections that, while never uninteresting, are somewhat less successful. To expect any different, especially in a work of this length, would be to hold it to an impossible standard. Somewhere in this 900-page book is a 600-page book. One that has the same story, but weighs less. Without those 300 pages, though, it wouldn’t be Neal Stephenson. It’s not possible to separate the essential from the decorative. Nor would we want that, even if it were were. Not only do his fans not mind the extra — it’s what we came for.

In this particular case, the extra stuff is also kind of the point. The mind-melting density of detail in Stephenson’s work can sometimes overwhelm or bog down the narrative, but in “Fall” it is very much in service of the book’s subject: reality, and how it might one day be simulated. How those simulations could be iterated and upgraded over time, through technological progress and at great financial cost, to an arbitrary degree of verisimilitude. How the resources of our “Meatspace” civilization would increasingly become inputs and raw material for the creation and improvement of a digital civilization (“Bitworld”), gradually sucking all of humanity into the Matrix in the process. Exploring the implications and possibilities of this, on a grand and granular scale, plays to Stephenson’s strengths. This is a case of author and substance and story and style all lining up; a series of lenses perfectly arranged to focus the power and precision of Stephenson’s laser-beam intellect.

Saturday Poem

Notice

This evening, the sturdy Levi’s
I wore every day for over a year
& which seemed to the end
in perfect condition,
suddenly tore.
How or why I don’t know,
but there it was: a big rip at the crotch.
A month ago my friend Nick
walked off a racquetball court,
showered,
got into this street clothes,
& halfway home collapsed & died.
Take heed, you who read this,
& drop to your knees now & again
like the poet Christopher Smart,
& kiss the earth & be joyful,
& make much of your time,
& be kindly to everyone,
even to those who do not deserve it.
For although you may not believe
it will happen,
you too will one day be gone,
I, whose Levi’s ripped at the crotch
for no reason,
assure you that such is the case.
Pass it on.

The Auden Course: Who could survive such a feast, let alone digest it?

Wilfred M. McClay in The Hedgehog Review:

In the fall of 1941, during a stint as a visiting faculty member at the University of Michigan, the poet W.H. Auden offered an undergraduate course of staggering intellectual scope. “Fate and the Individual in European Literature,” as it was titled, is not anything he is known for. Indeed, it is a sad reflection on the preoccupations of literary biography that, while we know far more than any sane person would ever want to know about Auden’s desperately unhappy love life, we know little about the origins or trajectory of this remarkable course. It is mentioned only in passing in some of the biographical accounts of Auden’s life and in a few testimonials from students who took the course (including Kenneth Millar, better known by his detective-fiction pseudonym Ross McDonald). Otherwise, it has gone largely unnoticed or unremarked upon.

That is, until recently. Seventy-one years after “Fate and the Individual in European Literature” came and went, a faded, marked-up copy of Auden’s original one-page syllabus was posted online by the literary scholar Alan Jacobs of Baylor University. Soon an image of that copy was circulating far and wide on the Internet, eliciting a surprising amount of commentary. Scholars and writers were excited by the syllabus, originally uncovered by Auden’s literary executor Edward Mendelson, because it provided them with a list of texts that Auden himself, one of the greatest poets and critics of the twentieth century, considered central to the Western intellectual and literary tradition. It was like a guided tour of the essential furnishings of a great poet’s mind.
