Five Words I Hate

by Mike Bendzela

Part of a run of my unsustainable, non-organically grown tomato plants

The words are fine, and some of the concepts they represent rather appealing, actually. It’s the usages to which they are put that bug me, usages that are by turns deceiving, dishonest, obfuscating, bogus, hokey, and euphemistic. There is a theme binding them all together, one concerning us humans’ exploitation of the wild world. The words pertain to how we use “resources,” which I define as the materials that make up the planet and its life as viewed through a bottomless stomach. These terms are unthinkable without our having domesticated ourselves and our surroundings: I cannot imagine our foraging ancestors in the Pleistocene having need of such words. Only a creature in a broken relationship with its planet needs a special terminology to salve its wound. Such words allow us to entertain feelings of wholesomeness while engaged in plunder.

1. Organic

Originally, pertaining to organisms. That’s the simple root. For a long time, matter associated with organisms was thought to be special because it was alive. Surely a vital force animated such material. Then a chemist name Friedrich Wöhler managed to produce urea — a component of urine — without having to pee in a bottle. He found it could be produced from ordinary, dead matter as well as through the processes of life. Thus began organic chemistry — the study of the properties of the carbon atom. At that moment, the word bifurcated, with continuing absurd consequences.

Among farmers, some pursued the synthetic way initiated by the likes of Wöhler (think Norman Borlaug and industrial agriculture), while others clung to vitalist notions, such as those promulgated by occultist Rudolph Steiner, whereby the products of living systems were privileged, “synthetics” be damned, bringing us the current linguistic mess. Organic food enthusiasts parted ways with the organic chemists around the beginning of the twentieth century, with “organic” gaining positive connotations and “chemical” negative ones.

Today the United States has the government-sanctioned term “organic” to describe a veritable Leviticus of “Allowed” and “Prohibited” substances and practices put into place to ensure that a farm is, well, organic. The term now conflicts with the scientific, chemical definition in just about every way. Read more »

A Footnote to the Surrealism Centenary: Le Grand Jeu

by Gus Mitchell

The following piece is my own minor contribution to the “Surrealism Centenary.” I begin with a disavowal of the entire “2024 centenary” enterprise, which seems to have added little to our appreciation of the group, and because I would question allowing Andre Breton, great though he sometimes was, to continue to define the wildly heterodox big bang to which he claimed total definition in October 1924.

Let us begin to celebrate the spirit of the surreal again. True to that spirit, let us slough off the burden of officialism and of art history. Let us not be bound to Breton or (heaven help us) Dali any longer.

This year should begin an overhaul of correction to the Anglophone ignorance of the movement’s noblest, most enduring, and still-dangerous representatives, who always were the outcasts, misfits, and weirdos among those proudly self-proclaimed outcasts, misfits, and weirdos.

Of these, a host of obscurer names and out of print-translations can be dug into online.

What I outline here is merely my favourite example.

In the 1910s, a quartet of teenaged artistic comrades in provincial France––Rene Daumal, Robert Gilbert-Lecompte, novelist Roger Vailland and Robert Meyrat––began a drug-fuelled quest into what they termed “experimental metaphysics”. After forming something of an adolescent secret society/artistic movement (which they dubbed Simplisme) this core quartet moved to Paris, made some older acquaintances and formed a short-lived journal: Le Grand Jeu (The Great Game) of which only three issues appeared, between 1928 and 1932. (The essence of this work and an essential English handbook to the group can be found in the English translation Theory of the Great Game, edited by Dennis Duncan, pictured above.) Read more »

Autocracy, Kleptocracy and the Threat to Democracy

by Adele A. Wilby

Renowned and respected for her scholarship, her history of authorship of many books on dictatorship and her political experience, is it any wonder that Anne Applebaum’s new book Autocracy, Inc. The Dictators Who Want to Run the World has been so critically received; she is an expert on her subject. This slim volume provides us with an incisive exposition and analysis of how autocrats function in the world today, securing their own personal power and wealth, and in Applebaum’s view, posing a threat to democracies.

For Applebaum, autocratic regimes clearly pose a threat to democracies, but about which states is she referring? The number of autocrats is, according to her, extensive and includes communists, monarchists, nationalists and theocrats. On Applebaum’s ‘list’ of autocracies are, predictably, Russia, China, Iran, North Korea – the well-known adversaries of the West – amongst many others. ‘Softer autocracies and hybrid democracies, sometimes called illiberal democracies’ such as Turkey, Singapore and India also come under her purview. It appears that autocracies and ‘softer autocracies’ outnumber the democracies in the world today and most of the world’s population lives under such regimes, and that is the problem for Applebaum.

We learn from Applebaum that the ‘art’ of autocracy in the modern world is very much up to speed, taking advantage of a globalised world, involving sophisticated networks of ‘financial structures, a complex of security services – military, paramilitary, police – and technological experts who provide surveillance, propaganda and disinformation’. The apparatus deployed by autocrats to achieve their political and financial objectives are probably used by most states across the globe; it is the purpose for which they are used that irks Applebaum. In her view a ‘ruthless, single-minded determination to preserve their personal wealth and power’ drives the autocrats in the world today. Read more »

Bad Reading

by Richard Farr

A detail from one of Abu Zubaydah’s drawings.

For several weeks I’ve had an article by the excellent Rick Perlstein squatting unread in my Ought-To-Read list. The title is Everything You Wanted to Know About World War III but Were Afraid to Ask. I am afraid to ask: although I ought to want to know, right now I don’t. “The world is too much with us”: unlike Wordsworth, but like you perhaps, I read the latest every day about Gaza, the Ukraine, South Sudan, the West Antarctic ice sheet, and another poll reminding me that tens of millions of my fellow citizens think a poisonous thug with a criminal record will make America great again. Sometimes you just have to switch off and leave the world behind. Even if you’d feel guilty being reminded that you haven’t been paying attention to Syria, Venezuela, the Rohingya, the Uyghurs, the women of Afghanistan, the children working in cobalt mines in the DRC, or the disturbing fact that people are actually out there buying Boris Johnson’s memoirs. 

I was thinking about this reality-fatigue recently while struggling to finish a different book. Look on the bright side: I’m not going to bore you with an account of the experience, which I have fairly often, of picking up a novel that has been declared “plangent” and “luminous” (or, that champion among meaningless back cover standbys, “fiercely original”) and  feeling embarrassed that I don’t get what the fuss is about. No, I’m going to address something more important than that: the experience of trying to read an excellent book, and feeling embarrassed that I barely had the moral fortitude to work through its contents.

Bottoms Up and the Devil Laughs. You have to get a long way in before you uncover the source of the title, but it’s worth the wait. The subject is 9/11, tangentially. But really the subject is our crimes, our brutalities, our layer cake of madnesses and delusions in the wake of 9/11. The battalion upon red-smeared gray battalion of ugly details we either chose not to learn, or chose to forget, or chose to swallow our government’s lies about. All that — and it’s about the uses and abuses, especially in the Land of Liberty, of virtually limitless surveillance.

Not to be outdone by her own title, Kerry Howley has invented in this book what as far as I can see is an entirely original style of writing in the genre of investigative journalism. We think we know what this kind of thing is supposed to sound like, and it’s not supposed to sound like someone responding to a bad hangover by having a panic attack and then swallowing a handful of amphetamines. But Howley’s sometimes hallucinatory style is a revelation: finally, here’s a voice that suits and perfectly illuminates the material. Read more »

The Statistical Margin of Error – Evaluating the Polls, Weighing the Cows

by John Allen Paulos

Every time I read or watch anything about the election I hear some variant of the phrase “margin of error.”  My mathematically attuned ears perk up, but usually it’s just a slightly pretentious way of saying the election is very close or else that it’s not very close. Schmargin of error might be a better name for metaphorical uses of the phrase.

To be fair, the phrase is often supplemented with precise numbers (plus or minus 1.5%, for example) that purport to quantify exactly how tight the race is (or isn’t).  Unfortunately these numbers are not as reliable as they might seem. The problem is that an enabling condition for this precision is that a random sample of voters be polled and the larger it is, the better.

A few technical remarks on the meaning of the margin of error in the next three paragraphs, which can be skimmed or skipped.

The basic qualitative idea: If we imagine many random samples of voters being taken, the sample percentages supporting a candidate will vary from sample to sample, of course, but these sample percentages will naturally cluster around the true percentage, P, of voters supporting the candidate in the whole population.

Importantly, this clustering of the sample probabilities can be described more quantitatively if we’re dealing with random samples of voters. In fact, if we assume that p is the percentage of voters supporting candidate A in a random sample and n is the number of voters in the sample, then we can get a good estimate of P, which is what we really want to know.

Specifically, the interval ranging from -2√[p(1-p)/n] to +2√[p(1-p)/n] will encompass, P, the percentage of voters in the whole population supporting candidate A, about  95% of the time.

Half of the above interval, which will vary a bit depending on p in the particular sample taken, is the margin of error. Since n appears in the denominator, the larger the sample is, the narrower the interval encompassing P. Read more »

Poem by Jim Culleny

I saw myself
a ring of bone
I saw myself
in the clear stream
of all of it
 
and vowed,
always to be open to it
that all of it
might flow through
 
and then heard
“ring of bone” where
ring is what a

bell does

Lew Welch

Down to the Bone

If I could un-ring certain bells and un-wind time I
would, but can’t, so instead, I’ll just ride this bucket
of bones till the wheels fly off; till ball-joints grind
and drop from sockets; till this xylophone of ribs
riffs the music of the spheres, until my funny bone
tells it’s last joke; till my shoulder blades cleave the
universe in two and find the nut within; until I’m
hipper than both hips and happier; till I’m savvy at
last, slicker than elbow grease, and mute as a smart
metatarsal; until I’m wiser than a thought-stuffed
skull: until I knee-cap my inner sonofabitch to stop
his useless jawin’ so I can hear one clear day
resound off tiny anvils and ride the lyrical looped
song of a backyard bird round Lew Welch’s ring of
bone   —Instead I’ll just splint what needs splinting
right here at home.

AI: Seven Ways to Challenge Philosophy

by Alexandre Gefen and Philippe Huneman

Philosophical reflection on artificial intelligence (AI) has been a feature of the early days of cybernetics, with Alan Turing’s famous proposals on the notion of intelligence in the 1950s rearming old philosophical debates on the man-system or man-machine and the possibly mechanistic nature of cognition. However, AI raises questions on spheres of philosophy with the contemporary advent of connectionist artificial intelligence based on deep learning through artificial neural networks and the prodigies of generative foundation models. One of the most prominent examples is the philosophy of mind, which seeks to reflect on the benefits and limits of a computational approach to mind and consciousness. Other spheres of affected philosophies are ethics, which is confronted with original questions on agency and responsibility; political philosophy, which is obliged to think afresh about augmented action and algorithmic governance; the philosophy of language; the notion of aesthetics, which has to take an interest in artistic productions emerging from the latent spaces of AIs and where its traditional categories malfunction; and metaphysics, which has to think afresh about the supposed human exception or the question of finitude.

In this text we want to indicate what are the new frontiers of philosophical speculation about artificial intelligence, now that GPT and other kinds of LLMs went public.

Knowing and Thinking: What Do AIs Tell Us?

If the currently established link between AI, cognitive science, and philosophy of mind is new, then philosophically questioning artificial intelligence requires us to place many questions in the long term. The project to improve human life by automating cognitive tasks, as radically original as it seems to us since the arrival of ChatGPT, develops one of Aristotle’s old intuitions about automata that would solve our routine tasks and replace our slaves. The milestones are famous automata such as Vaucanson’s duck and the mechanical Turk, right up to the exuberant robots of Boston Dynamics. To take just two examples, the congruences between the pragmatic philosophy of language proposed by Wittgenstein and how Large Language Models (LLMs) synthesize usages to generate thought probabilistically is patent, as is the link between modern cybernetics, which separates software and hardware, and the idea that thought is realizable in multiple ways, a notion formulated in the 1950s by Hilary Putnam and Jerry Fodor (sometimes called functionalism). One of these realizations would be human thought, often located “inside of” the brain, while the other would be a machine-implemented thought. Modern artificial intelligence has its roots in a long history of formalizing thought and logic. Read more »

Storytelling Techniques in Film: Affliction, Badlands, and L’Eclisse

by Derek Neal

The opening credits of Affliction (1997) feature small, rectangular images that fill only half the screen. You wonder if something is wrong with the aspect ratio, or if the settings have been changed on your television. A succession of images is placed before the viewer: a farmhouse in a snowy field, a trailer with a police cruiser parked in front, the main street of a small, sleepy town, the schoolhouse, the town hall. The last image is a dark, rural road, with a mountain in the distance. Finally the edges of the image expand, fill the screen, and a voice begins to narrate:

This is the story of my older brother’s strange criminal behavior and disappearance. We who loved him no longer speak of Wade. It’s as if he never existed. By telling his story like this, by breaking the silence about him, I tell my own story as well. Everything of importance, that is, everything that gives rise to the telling of this story occurred during a single deer hunting season in a small town in upstate New Hampshire where Wade was raised, and so was I. One night, something changed and my relation to Wade’s story was different from what it had been since childhood. I marked this change by Wade’s tone of voice during a phone call two nights after Halloween. Something I had not heard before. Let us imagine that around eight o’clock on Halloween Eve…

Then the narrator’s voice disappears, and we are in the car with Wade, played by Nick Nolte, and his daughter. We are in the story, we are ready to be swept away, or in the case of this movie, submerged into the depths, but we have been prepared in such a way—starting from outside the story, outside the narrative—that we are aware of the artificiality of what we are seeing. Affliction tells us that it is a movie. The small images, which look like postcards, are presented to us as miniature models of different sets. The farmhouse becomes “THE HOUSE.” The main street becomes “MAIN STREET.” While they will take on specific characteristics within the movie, we know from the prologue that they are eternal, and we will be reminded of this at the end as well.

The voiceover achieves a similar effect. The narrator, played by Willem Defoe, removes tension and drama from the plot by spoiling the ending: Wade becomes a criminal and disappears. He does not even attempt to convince us that the story is real, that it actually happened, because he says, “Let us imagine.” Is this not bad storytelling? It may be appropriate for a children’s story, a fairy tale, but for a mature film like Affliction, a film dealing with murder, paranoia, and male violence?  Shouldn’t a story like this try to convince its audience that it’s real, by building up a wealth of detail and creating realistic, lifelike characters? Perhaps a certain type of story, but not this one. Read more »

Forget Turing, it’s the Tolkien test for AI that matters

by John Hartley

With CAPTHCHA the latest stronghold to be breeched, following the heralded sacking of Turing’s temple, I propose a new standard for AI: The Tolkien test.

In this proposed schema, AI capability would be tested against what Andrew Pinsent terms ‘the puzzle of useless creation’. Pinsent, a leading authority on science and religion asks, concerning Tolkien: “What is the justification for spending so much time creating an entire family of imaginary languages for imaginary peoples in an imaginary world?”

Tolkien’s view of sub-creation framed human creativity as an act of co-creation with God. Just as the divine imagination shaped the world, so too does human imagination—though on a lesser scale—shape its own worlds. This, for Tolkien, was not mere artistic play but a serious, borderline sacred act. Tolkien’s works, Middle-earth in particular, were not an escape from reality, but a way of penetrating reality in the most acute sense.

For Tolkien, fantasia illuminated reality insofar is it tapped into the metaphysical core of things. The the artistic creation predicated on the creative imagination opened the individual to an alternate mode of knowledge, deeply intuitive and discursive in nature. Tolkien saw this creative act as deeply rational, not a fanciful indulgence. Echoing the Thomist tradition, he viewed fantasy as a way of refashioning the world that the divine had made, for only through the imagination is the human mind capable of reaching beyond itself.

The role of the creative imagination, then, is not to offer a mere replication of life but to transcend it. Here is the major test for AI, for in doing so, it accesses what Tolkien called the “real world”—the world beneath the surface of things. As faith seeks enchantment, so too does art seek a kind of conversion of the imagination, guiding it towards the consolation of eternal memory, what Plato termed ‘anamnesis’. Read more »

Becoming What We Are: Authenticity as a Practice

by Gary Borjesson

Become what you are, having learned what that is. —Pindar

[To protect their privacy, I have changed identifying details of those mentioned here.]

Aristotle

What do we want for our lives? It’s a peculiarly human question; other animals don’t appear to be worrying about it. I’ve asked myself this question, sometimes with curiosity, sometimes more desperately, for as long as I can remember. I’m always moved when patients raise it in their therapy. A man who retired from a successful career said that when he looks into the future without the mantle of his professional title and status, he feels empty and lost, ashamed that at 70 he doesn’t know what he wants.

Sometimes we raise the question ourselves; sometimes the world raises it for us. Another patient, whose boyfriend just “dumped” her, is wrestling with her alcohol use. The men she wants in her life don’t want an alcoholic in theirs. She’s angry at the thought of sobering up for someone else, “Wouldn’t that be inauthentic?” At the same time, she (authentically) wants a partner in her life.

She knows what most of us know, that we want to be authentic. By “authenticity” I mean living in a way that is true to oneself and to one’s situation in the world. (For the bigger philosophic picture, see my previous column, Reclaiming Authenticity as an Ethical Ideal.) Authenticity resonates because it is that rare thing, an ideal that most of us embrace—despite our divergent religious, ethnic, social, and political values. After all, each of us faces (or not) the question of how to become our best selves.

Although we must ask and answer that question for ourselves, I will suggest a few core principles that can guide our way. I’ll start with Aristotle’s view, that the one thing we all want from life is to flourish, which means living in such a way as to be fulfilling our nature. This might sound about as helpful as telling someone who is struggling, “Just be true to yourself!” How do we even know what our true self is? If we’re a lonely alcoholic, is our true self more of the same, or is it sober and in a relationship?

We can find some guidance by unpacking two principles of flourishing that extend to living authentically. Read more »

Reviewed, Ken Ham’s The Lie; Unravelling the Myth of Evolution/Millions of Years. And why we need to pay attention

by Paul Braterman

You need to take Ken Ham seriously. This entrepreneurial Brisbane high school teacher has put together the world’s largest Young Earth creationist organization, Answers in Genesis (AiG). This has a worldwide presence, publishes its own magazine, Answers, and emails a constant stream of highly repetitive messages to its followers. It has built the Creation Museum in Kentucky, as well as the Ark Encounter, featuring a (very unbiblical) so-called replica of Noah’s Ark, and now plans a replica of the Tower of Babel. Its annual income (June 2022 filing) was over $60 million, its YouTube channel has 667,000 subscribers, and its website claims over a million visits each month.

So what? Bible Belt lunatic fringe? Unfortunately no. AiG has allies who are close to the center portion of power, and who will be even closer to the center of power should Donald Trump once again become President.

Ken Ham has among his friends Mike Johnson, Speaker of the US House of Representatives, whose law firm represented AiG pro bono in a successful attempt to ensure Kentucky State funding for its activities, despite its fundamentally religious nature, which goes so far as to require all employees accept its six-day creationist Statement of Faith. And among the contributors to its magazine is Calvin Beisner, director of the Cornwall Alliance, whose entire purpose is to deny the importance of human-caused climate change. Cornwall in turn has direct links to the Heartland Institute and to the Heritage Foundation, authors of Project 2025.

If you have not studied modern creationism, you may well think that it is a curious aberration, like flat-earthism, regrettable in its denial of whole areas of science, but otherwise (!) harmless. Not so. Read more »

We’ve Never Really Studied the Female Body

by Rebecca Baumgartner

For a while now, the slogan “Trust the experts” has been a liberal shibboleth meant to imply endorsement of scientific consensus. Despite agreeing, in principle, with what the phrase is meant to signal, I’ve always been bothered by this slogan. Part of it is that as I get older, I realize more and more clearly that everyone is just winging it – even experts. Nobody really knows what they’re doing, at least not to the degree they want you to think they do. Another part of my cynicism about trusting experts is that I’ve personally been let down by them, as we all have to one degree or another. These experiences start to pile up in the course of life, especially if you’ve been unlucky enough to need the services of experts like doctors on a regular basis.

Photo By: Kaboompics.com

But alongside this cynicism, I recognize that the opposite stance – “Don’t trust the experts” – isn’t tenable either. We have to trust experts if we want to live as active members of society rather than in a bunker full of canned beans wearing tinfoil hats. 

I was finally able to understand my way around this dilemma when I came across “The Trouble with Expertise” in The Philosophers’ Magazine. In it, clinical ethicist Jamie Watson says:

“Medical researchers have exploited people of colour, obstetricians have ignored medical decisions from women in labour, pharmaceutical corporations have conspired to increase addiction, and trans patients are routinely stigmatised or refused care. There are lots of reasons to be sceptical about experts. But it’s important to note that those reasons have nothing to do with expertise. The trouble comes because of the power experts have to put people in compromising positions and to use their positions in ways that harm others.”

This sums up why I find it more helpful to think of trust in terms of the system that an expert operates within rather than in terms of any individual expert. I trust the scientific method and the peer-review process, because while neither is perfect, they have internal rules and norms about finding and correcting errors. An individual expert is only trustworthy to the extent that they live up to the standards imposed on them by their system of expertise. Read more »

God And Insurance: Ten Comparisons Between Egypt And Germany

by Eric Schenck

The longer you’re in a new country the more it becomes a relationship. It starts out wonderful. You never knew a place could understand you like this. Everything is fun and exciting and “Oh my God just so different!” But then reality sets in. And, with enough time, the things that start out oddly charming begin to irritate you. That’s happened to me twice. I lived in Egypt for three years and Germany for five.

Moving to both countries are the two best decisions I’ve ever made. Bar none. It’s undeniable what they’ve given me. It’s also undeniable that they really pissed me off. Here are ten things about Egypt and Germany, compared side-to-side. Written, of course, with all the love in my heart.

1) The People

Egypt

They never show up on time. That’s clear straight from the beginning. 

This isn’t just me being closed-minded as a Westerner. Egyptians admit to their tardiness with glee. 

Khamis duh-ay bess.

“Only 5 minutes.”

I will hear this thousands of times the three years I live there. I swear I notice the smile in an Egyptians’ voice every time they say it. I know it’s a lie and so do they.

Egyptians also laugh at everything.

Their insistence that everything is probably just fine will charm me to no end. 

Germany

If a German tells you they’re going to do something, they’re going to do it. It’s as simple as that. 

Never have I met a nation as unfailingly trustworthy.

They’re also so punctual that it can get slightly creepy.

“Oh, you need help moving apartments at 7:30 AM on a Tuesday six months from now? It’s in my schedule.”

Six months later, you look out your window on a Tuesday morning, and Hans is waiting there at 7:25. 

Delightful. Read more »

The Temptations of Nostalgia

by Rachel Robison-Greene

Last weekend in Northern Utah, the fall colors in the mountains were at their peak. The days were still hot, but the mornings and evenings were cool. The sun was beginning to set a little earlier and most of the doorsteps in our quiet town were peppered with multicolored autumn gourds. An old movie theater downtown, built in 1924 in art deco style, was showing Alfred Hitchcock’s Psycho. My husband and I decided to go.

Before the film, the theater featured “previews” of older Halloween movies: trailers for the original Halloween, Pet Sematary, and both of the original Ghostbusters films. The evening kicked off with a screening of the Michael Jackson music video Thriller. Clutching my cheap, overly salted popcorn and my flat Diet Coke, I sank into a comfortable nostalgia.

One straightforward way in which nostalgia is pleasant is that it involves memories of things that we once enjoyed but perhaps have not kept present before our minds. I don’t think this is all there is to it. I noticed that nostalgia, on this occasion, was not only comfortable—it felt like a relief. An escape. Being present in the current moment is hard work. One of the reasons that nostalgia is pleasant is that it presents us with all of the desirable parts of having an identity without any of the unpleasant responsibilities of crafting it. We can take advantage of the asymmetrical relation in which we stand to our past selves on one hand and our future selves on the other.

When I look to the future I wonder: will I have an identity that I recognize and endorse? In philosopher Bernard Williams’ famous paper “The Makropulos Case: Reflections on the Tedium of Immortality,” he tells the story of an opera by the same name in which Elina Makropulos, a woman born in the 16th century was given an elixir of life by her court physician father. So long as she goes on taking the elixir, she goes on living. The opera is set in the contemporary era, and Elina has become desperately bored. “It is all the same” she laments, “singing and silence.”

Williams uses Elina’s case to argue that immortality would be undesirable. Inevitably, we would all either become suicidally bored or we would change so much that we wouldn’t recognize ourselves—we’d turn into people our past selves wouldn’t relate to or endorse. In the worst case, we might even turn into people who we’d rather die than become. In the end, Elina gives up on the prospect of immortality, stops taking the elixir, and dies. Read more »

What Tangled Webs: The Hopf Fibration And Physics III

by Jochen Szangolies

The Bloch sphere, the state space of a single qubit, as the Hopf fibration. To every point, a circle is associated which keeps track of the phase degree of freedom, according to the matching colors.

In the previous two installments of this series ([1], [2]), I have been engaged in the project of communicating a bit of the intuition behind the abstract notions of physics (and the necessary mathematics). My guiding principle in this attempt (essay in the literal sense) has been a famous quote of Hungarian mathematician and polymath John von Neumann: “In mathematics you don’t understand things. You just get used to them.”

This is an initially surprising notion. Mathematics, it seems, is the domain of pure intellect, where great minds wrestle with arcane concepts to squeeze droplets of eternal truth from Platonic realms of pure form. How does this square with ‘just getting used to it’?

I think that the poles of this apparent dichotomy are not as far removed as it might seem. The traditional view seems to emphasize singular mental effort, while von Neumann intimates, rather, repeated exposure—training, or diligent practice. The first is the province of what Daniel Kahnemann calls ‘System 2’, the effortful, explicit, step-by-step mode of reasoning that is often implicitly meant simply by ‘thought’. We analyze novel concepts, break them down into their components, resolve them into a step-by-step, algorithmic sequence, much like taking apart a watch to find what makes it tick.

But practice targets a different, implicit and automatic mode of thought: that of ‘System 1’, the associative, fast and heuristic mode of cogitation at work when you perform activities that require little explicit thought. Take riding a bike: there is no hope to learn it purely via the System 2-mode—that is, you can’t read a book on bike-riding, hop on and be off on your merry way. You need, rather, to train—to try, fail, and try again, until you get it right; and once you do, you’ll find yourself at a loss explaining exactly how. But after you have learned to do it, it ceases to become an explicit effort, instead happening apparently ‘by itself’, without you having to attend to the precise sequence of motions that keep your feet cranking the pedals, your arms turning the handles, and your entire body holding the balance.

Practice imparts an understanding that can’t be achieved by direct instruction. Getting used to something is a way to understand it that bypasses and complements the step-by-step process of analytical reason, a way to appreciate it at an intuitive Gestalt level rather than from the bottom up in terms of its individual components.

This is of course well appreciated by working physicists and mathematicians. But both popular science writing and popular culture at large paint a radically different picture. Read more »

Merry-Go-Rounds

by Barry Goldman

The New York Times had a piece recently about a clever hustle called station flipping. It involves Citi Bikes, the blue rental bikes you see all over New York City. It seems the natural movement of people and bikes around the city results in periodic imbalances. Sometimes there are too many bikes in a docking station, other times there are too few. So Lyft, the company that owns Citi Bike, implemented a program that rewarded people for moving bikes from one station to another to correct those imbalances. The miracle of modern information technology enabled the company to track the location of its bikes with precision and to tweak the reward structure in real time. The system awarded points, and the points could be redeemed for cash. Moving a bike from a full docking station to an empty one could earn a “Bike Angel” up to $4.80.

People respond to incentives. They also, in every system everywhere, “work the points.” As a direct and inevitable result, people figured out how to game the Bike Angel system. They realized they didn’t have to wait for the natural movement of bikes and people to create shortages and surpluses, they could manufacture them.

The algorithm updated every 15 minutes. Some docking stations are only a block apart. That means a group of aerobically fit Angels can empty one docking station and fill another by riding bikes to the empty station and running back to the full station until the conditions are reversed. If they can do this before the system updates, they can earn the maximum for each ride. Then, when the full station is empty and the empty station is full, they can reverse the process and do it again. Before too long some enterprising Bike Angels were earning up to $6,000 a month.

The company, predictably, was not amused. It says station flipping distorts the market and games the system.
