Wittgenstein’s Forgotten Lesson

Ludwig Wittgenstein is regarded by many, including myself, as the greatest philosopher of this century. His two great works, Tractatus Logico-Philosophicus (1921) and Philosophical Investigations (published posthumously in 1953) have done much to shape subsequent developments in philosophy, especially in the analytic tradition. His charismatic personality has fascinated artists, playwrights, poets, novelists, musicians and even movie-makers, so that his fame has spread far beyond the confines of academic life.

And yet in a sense Wittgenstein’s thought has made very little impression on the intellectual life of this century. As he himself realised, his style of thinking is at odds with the style that dominates our present era. His work is opposed, as he once put it, to “the spirit which informs the vast stream of European and American civilisation in which all of us stand.” Nearly 50 years after his death, we can see, more clearly than ever, that the feeling that he was swimming against the tide was justified. If we wanted a label to describe this tide, we might call it “scientism,” the view that every intelligible question has either a scientific solution or no solution at all. It is against this view that Wittgenstein set his face.

Scientism takes many forms. In the humanities, it takes the form of pretending that philosophy, literature, history, music and art can be studied as if they were sciences, with “researchers” compelled to spell out their “methodologies”—a pretence which has led to huge quantities of bad academic writing, characterised by bogus theorising, spurious specialisation and the development of pseudo-technical vocabularies. Wittgenstein would have looked upon these developments and wept.

There are many questions to which we do not have scientific answers, not because they are deep, impenetrable mysteries, but simply because they are not scientific questions. These include questions about love, art, history, culture, music-all questions, in fact, that relate to the attempt to understand ourselves better. There is a widespread feeling today that the great scandal of our times is that we lack a scientific theory of consciousness. And so there is a great interdisciplinary effort, involving physicists, computer scientists, cognitive psychologists and philosophers, to come up with tenable scientific answers to the questions: what is consciousness? What is the self? One of the leading competitors in this crowded field is the theory advanced by the mathematician Roger Penrose, that a stream of consciousness is an orchestrated sequence of quantum physical events taking place in the brain. Penrose’s theory is that a moment of consciousness is produced by a sub-protein in the brain called a tubulin. The theory is, on Penrose’s own admission, speculative, and it strikes many as being bizarrely implausible. But suppose we discovered that Penrose’s theory was correct, would we, as a result, understand ourselves any better? Is a scientific theory the only kind of understanding?

Well, you might ask, what other kind is there? Wittgenstein’s answer to that, I think, is his greatest, and most neglected, achievement. Although Wittgenstein’s thought underwent changes between his early and his later work, his opposition to scientism was constant. Philosophy, he writes, “is not a theory but an activity.” It strives, not after scientific truth, but after conceptual clarity. In the Tractatus, this clarity is achieved through a correct understanding of the logical form of language, which, once achieved, was destined to remain inexpressible, leading Wittgenstein to compare his own philosophical propositions with a ladder, which is thrown away once it has been used to climb up on.

In his later work, Wittgenstein abandoned the idea of logical form and with it the notion of ineffable truths. The difference between science and philosophy, he now believed, is between two distinct forms of understanding: the theoretical and the non-theoretical. Scientific understanding is given through the construction and testing of hypotheses and theories; philosophical understanding, on the other hand, is resolutely non-theoretical. What we are after in philosophy is “the understanding that consists in seeing connections.”

Non-theoretical understanding is the kind of understanding we have when we say that we understand a poem, a piece of music, a person or even a sentence. Take the case of a child learning her native language. When she begins to understand what is said to her, is it because she has formulated a theory? We can say that if we like—and many linguists and psychologists have said just that—but it is a misleading way of describing what is going on. The criterion we use for saying that a child understands what is said to her is that she behaves appropriately-she shows that she understands the phrase “put this piece of paper in the bin,” for example, by obeying the instruction.

Another example close to Wittgenstein’s heart is that of understanding music. How does one demonstrate an understanding of a piece of music? Well, perhaps by playing it expressively, or by using the right sort of metaphors to describe it. And how does one explain what “expressive playing” is? What is needed, Wittgenstein says, is “a culture”: “If someone is brought up in a particular culture-and then reacts to music in such-and-such a way, you can teach him the use of the phrase ‘expressive playing.’” What is required for this kind of understanding is a form of life, a set of communally shared practices, together with the ability to hear and see the connections made by the practitioners of this form of life.

What is true of music is also true of ordinary language. “Understanding a sentence,” Wittgenstein says in Philosophical Investigations, “is more akin to understanding a theme in music than one may think.” Understanding a sentence, too, requires participation in the form of life, the “language-game,” to which it belongs. The reason computers have no understanding of the sentences they process is not that they lack sufficient neuronal complexity, but that they are not, and cannot be, participants in the culture to which the sentences belong. A sentence does not acquire meaning through the correlation, one to one, of its words with objects in the world; it acquires meaning through the use that is made of it in the communal life of human beings.

Capitalism Redefined

Prosperity in a society is the accumulation of solutions to human problems.

For everyone but the top 1 percent of earners, the American economy is broken. Since the 1980s, there has been a widening disconnect between the lives lived by ordinary Americans and the statistics that say our prosperity is growing. Despite the setback of the Great Recession, the U.S. economy more than doubled in size during the last three decades while middle-class incomes and buying power have stagnated. Great fortunes were made while many baby boomers lost their retirement savings. Corporate profits reached record highs while social mobility reached record lows, lagging behind other developed countries. For too many families, the American Dream is becoming more a historical memory than an achievable reality.

These facts don’t just highlight the issues of inequality and the growing power of a plutocracy. They should also force us to ask a deeper set of questions about how our economy works—and, crucially, about how we assess and measure the very idea of economic progress.

How can it be that great wealth is created on Wall Street with products like credit-default swaps that destroyed the wealth of ordinary Americans—and yet we count this activity as growth? Likewise, fortunes are made manufacturing food products that make Americans fatter, sicker, and shorter-lived. And yet we count this as growth too—including the massive extra costs of health care. Global warming creates more frequent hurricanes, which destroy cities and lives. Yet the economic activity to repair the damage ends up getting counted as growth as well.

Our economic policy discussions are nearly always focused on making us wealthier and on generating the economic growth to accomplish that. Great debates rage about whether to raise or lower interest rates, or increase or decrease regulation, and our political system has been paralyzed by a bitter ideological struggle over the budget. But there is too little debate about what it is all for. Hardly anyone ever asks: What kind of growth do we want? What does “wealth” mean? And what will it do for our lives?

Cargo Bikes Are the New Minivans for Cycling Families


[ed. Great. Count me in as someone not enamored with this new trend. It might be carbon friendly and good exercise but until cities are designed for real hybridized use of our transit corridors (and not just painted 'bike lanes' with no real barriers), forget it. This is just another step in ratcheting up the existing conflict of who gets to claim right-of-way. Good design would include automobile, bike, pedestrian... hell, even golf cart friendly options that are integated or separated from the start, depending upon their intended purpose. This isn't.]

One fisherman uses a bike to deliver hundreds of pounds of salmon to local markets. A mom who regularly shuttles her two kids around town once tried to haul a twin mattress home. And some companies are using the bikes to deliver beer kegs or pick up recycling.

Cyclists are pushing the limits of what they can haul on cargo bikes — sturdy two-wheelers built to haul lots of stuff. The so-called SUV of bicycles are increasingly popular in pedal-friendly communities, from Washington state to Massachusetts.

Families are using the bikes to do everything they did on four wheels — schlepping kids to school, hauling groceries or running errands — without the hassle of finding parking. Some do it to help the environment in a small way or get exercise, while others say it's an easier, more fun way to get around.

“(Our) bike has turned into our go everywhere minivan,” said Julian Davies, a Seattle physician who regularly hauls his two kids in a cargo bike. (...)

It's still in the early adopter phase, but “it's picking up steam,” said Andy Clarke, president of the League of American Bicyclists. “It's a reflection of the growing utility of cycling, and the propensity to use bikes for more and more activities. It's giving people more options and flexibility.”

Cargo bikes can refer to any bike that hauls heavy loads. Many models out now are built to handle multiple people or loads up to about 400 pounds on a single frame. They can be a foot or two longer than typical bikes, and are often outfitted with a wheelbarrow-like box or shelf, in front or back. Some cost between $1,000 and $5,000. (...)

Madi Carlson, 41, regularly schlepps her two young kids along with their bikes on her pink long-tail bike, which has kids seats mounted over the rear of the bike. The three usually cover about 10 miles a day, riding between school, home, playdates and errands.

The Seattle mom considers it a challenge to carry absurd loads. She once tried to haul a box spring mattress, and made it six blocks before she had to call her husband for a lift.

“That damn box spring,” she laughed. “That's one of the problems with cargo bikes. You just want to carry bigger and more exciting loads. You just want to see what you can do.”

As for safety, Carlson said she bikes slowly and defensively and sticks to dedicated bike paths where possible. “I worry a lot more about accidents in the car,” she said.

Dylan's Electric Guitar Sells for Nearly $1M

Like Elvis' no-hips-allowed appearance on "The Ed Sullivan Show," or the Beatles' arrival in America, or Woodstock, it is considered one of the milestone moments in rock history: Bob Dylan going electric at the 1965 Newport Folk Festival.

On Friday, the Fender Stratocaster that Dylan plugged in at the festival sold for nearly $1 million — the highest price ever paid for a guitar at auction.

A buyer identified only as a private individual agreed to pay $965,000 at Christie's, including the auction house's fees, for the sunburst-finish electric guitar.

Dylan's legendary performance at the festival in Rhode Island 48 years ago marked his rupture with the folk movement's old guard and solidified his shift away from acoustic music, like "Blowin' in the Wind," toward amplified rock, such as "Like a Rolling Stone."

The raucous, three-song electric set was booed by some in the crowd, and folk purists saw Dylan as a traitor and a sellout.

But "his going electric changed the structure of folk music," said Newport Folk Festival founder George Wein, 88. "The minute Dylan went electric, all these young people said, 'Bobby's going electric. We're going electric, too.'"

Christie's had expected the guitar, which was sold with its original black leather strap and Fender hard-shell case, to go for far less, $300,000 to $500,000.

The previous record for a guitar sold at auction was held by Eric Clapton's Fender, nicknamed "Blackie," which sold at Christie's for $959,500 in 2004.

Dylan's guitar had been in the possession of a New Jersey family for nearly 50 years after the singer left it on a private plane.

The pilot's daughter, Dawn Peterson of Morris County, N.J., said her father asked Dylan's management what to do with the instrument, and nobody ever got back to him.

Yahoo’s Geek Goddess

By now the headline-getting series of events has become business lore. In the fall of 2011, New York moneyman Daniel Loeb, who runs the $14 billion hedge fund Third Point Capital, staged a raid on Yahoo, the well-known but struggling Silicon Valley company. After a brutal fight to depose the company’s C.E.O., he helped raid Google for one of its longest-serving and most famous executives, Marissa Mayer, then often called “the face of Google” or “Google’s glamour geek.” Last summer, on the same day that Yahoo announced that Mayer would be its new C.E.O.—becoming the youngest woman, at 37, to lead a Fortune 500 company—Mayer announced she was pregnant, thereby completing her journey from nerdy small-town Wisconsin girl to Stanford-educated engineer to business superstar to cultural idol. (...)

But a glittering surface often deflects attention from a messier reality, and that’s true with Mayer and Yahoo. No one wants to sound as if they aren’t rooting for Yahoo or for her, and because Mayer didn’t cooperate for this article, even her friends were often unwilling to speak on the record about her. She’s anything but easy to categorize, in ways that are both interesting and possibly troubling for Yahoo’s future. “She is a confusing person,” says someone who has worked with her closely. “It is a mistake to paint her as an angel or as a devil.” Another executive who worked with her agrees that she is a hard person to understand. “There are some parts of Marissa World that are just inexplicably weird,” he says. “It doesn’t add up.”

There are two things about Marissa Mayer upon which everyone agrees. One is that she’s among the smartest people they’ve ever met. The other is that she has a superhuman capacity for work. Mayer says that she needs only four hours of sleep a night and that she pulled 250 all-nighters in her first five years at Google. “I don’t really believe in burnout,” she said in a speech last year at New York’s 92nd Street Y. “A lot of people work really hard for decades and decades, like Winston Churchill and Einstein.”

This superhuman energy seems to have been part of her from her earliest years in Wausau, a small city northwest of Milwaukee that is best known for the insurance company that carries its name. She told Vogue that she always had at least one after-school activity per day, from ballet to ice-skating, to piano, swimming, debate team, and Brownies; she was a standout debater whose team won a Wisconsin state championship, a member of the pom-pom squad, the president of the Spanish Club, and the treasurer of the Key Club; she has also said that by junior high she was doing ballet 35 hours a week.

At a talk at Stanford, when Mayer was asked what made her successful, her answer was simple: “I like to work.” She went on to say that, when her father, who was an environmental engineer, came to a talk she was giving at Google, people swarmed him to ask about his daughter. When they asked, “Have you ever seen Marissa talk before?,” he answered, “No. I’m Marissa’s dad. I like to work.”

Mayer doesn’t seem to have been a popular kid, but she shows no signs of having been tormented in the usual ways that smart, small-town midwestern girls can be. “I got to live in a bubble,” she said at the Y. “I was really good at chemistry, calculus, biology, physics in high school, and my teachers were genuinely supportive of that.” Wausau West yearbook photos show her in a science seminar discussing the Wausau Chamber of Commerce survey on students and working hours, performing a pom-pom routine for a Bush-Quayle rally, and, on the debate team, telling a judge why voting rights for the homeless weren’t needed. (The yearbook had a feature describing debaters as “nerds with attitude.”)

If she had any insecurities, Mayer didn’t manifest them outwardly. “In high school, Marissa was wicked smart and she knew it (not cocky, but very confident)” is how Lief Larson, who went to high school with her and is now a technology entrepreneur in Minneapolis, described her in a blog post. “She was always 100% business, all the time. She was not known as a ‘popular,’ but she was highly involved/diligent.” Larson added, “What ever she did, she tried to make it perfect.”

She applied to 10 colleges, including Harvard, Yale, and Stanford. After being accepted by all of them, she created a spreadsheet, ranking the schools by criteria such as median S.A.T. scores. It yielded Stanford, where she initially planned to major in biology or chemistry, with the goal of becoming a pediatric neurosurgeon “who taught at a medical school while taking exceptional cases,” as she described it. Upon realizing that she could do that with a degree from a state school, she changed her major to symbolic systems, a Stanford major that combines philosophy, cognitive psychology, linguistics, and computer science.

Stealing Time

[ed. See also: Dirty Dying.]

In late August, I got an extra day — just an average day — with my father.

At 82, my dad had a whole litany of ailments: a bad heart, inferior lungs, failing eyesight, some skin cancer and a pesky wound on his leg that just wouldn’t heal. So, at the last minute, a day after my mother’s birthday, I detoured from a business trip over to Tampa to see them.

We didn’t do anything special. I made a bunch of work calls, returned emails, even took a nap. Dad paid some bills, opening up a little to me about the state of his finances, which he never did. He had his Social Security, a small pension and the money that he worked hard to save in 47 years as a union butcher for the A&P. Looking through an old tin box, I came across his Army discharge papers and discovered he’d been awarded three bronze stars — something else he’d never bothered to mention. Then he sat in his chair, hooked up to the oxygen he didn’t wear as much as he should, occasionally dozing off between reruns of “M*A*S*H” and “Bonanza.”

I took him to the doctor, where he got (for him) a pretty clean bill of health, and we went to the grocery store. I bought wine and some half-and-half for my coffee. He bought scratch-off lottery tickets — one for him and one to bring home to my mother. On the way home, in a half-sentence conversation that only a father and a son could have, he confirmed that yes, he did want to be cremated someday, and yes, that veterans’ cemetery where they buried Uncle Bob seemed like a nice spot.

Someone's Been Siphoning Data Through a Huge Security Hole in the Internet

[ed. NSA hacking into fiber optic cables? That's like so yesterday.]

In 2008, two security researchers at the DefCon hacker conference demonstrated a massive security vulnerability in the worldwide internet traffic-routing system -- a vulnerability so severe that it could allow intelligence agencies, corporate spies or criminals to intercept massive amounts of data, or even tamper with it on the fly.

The traffic hijack, they showed, could be done in such a way that no one would notice because the attackers could simply re-route the traffic to a router they controlled, then forward it to its intended destination once they were done with it, leaving no one the wiser about what had occurred.

Now, five years later, this is exactly what has happened. Earlier this year, researchers say, someone mysteriously hijacked internet traffic headed to government agencies, corporate offices and other recipients in the US and elsewhere and redirected it to Belarus and Iceland, before sending it on its way to its legitimate destinations. They did so repeatedly over several months. But luckily someone did notice.

And this may not be the first time it has occurred -- just the first time it got caught.

Analysts at Renesys, a network monitoring firm, said that over several months earlier this year someone diverted the traffic using the same vulnerability in the so-called Border Gateway Protocol, or BGP, that the two security researchers demonstrated in 2008. The BGP attack, a version of the classic man-in-the-middle exploit, allows hijackers to fool other routers into re-directing data to a system they control. When they finally send it to its correct destination, neither the sender nor recipient is aware that their data has made an unscheduled stop. (...)

BGP eavesdropping has long been a known weakness, but no one is known to have intentionally exploited it like this until now. The technique doesn't attack a bug or flaw in BGP, but simply takes advantage of the fact that BGP's architecture is based on trust.

To make it easy for e-mail traffic from an ISP in California to reach customers of an ISP in Spain, networks for these providers and others communicate through BGP routers. Each router distributes so-called announcements indicating which IP addresses they're in the best position to deliver traffic to, for the quickest, most efficient route. But BGP routers assume that when another router says it's the best path to a specific block of IP addresses, it's telling the truth. That gullibility makes it easy for eavesdroppers to fool routers into sending them traffic they shouldn't get.

When a user types a website name into his browser or clicks "send" to launch an e-mail, a router belonging to the sender's ISP consults a BGP table for the best route to the destination. That table is built from the announcements issued by ISPs and other networks declaring the range of IP addresses, or IP prefixes, to which they'll deliver traffic. The routing table searches for the destination IP address among those prefixes, and if two systems deliver traffic for the address, the one with the narrower, more specific range of prefixes "wins" the traffic.

For example, one ISP announces that it delivers to a group of 90,000 IP addresses, while another delivers to a subset of 24,000 of those addresses. If the destination IP address falls within both of these, the e-mail will get sent to the narrower, more specific one.

To intercept data, anyone with a BGP router or control of a BGP router could send out an announcement for a range of IP addresses he wished to target that was narrower than the chunk advertised by other network routers. The announcement would take just minutes to propagate worldwide and, just like that, data that should have headed to those networks would begin arriving to the eavesdropper's router instead.

Ordinarily, when an attacker tried to then forward the stolen traffic to its rightful destination, it would boomerang back to him, since other routers would still believe that his was the best destination for the traffic. But the technique demonstrated at DefCon, and now spotted in the wild, allows an attacker to send his announcement in such a way that it is delivered only to select routers. So, once the traffic passes through his router, it gets directed to its rightful destination through routers that never got the bogus announcement. The attack intercepts only traffic headed to target addresses, not from them.

Some Notes on the Making of Fried Chicken


[ed. I thought about this when my mom died: how the learned (and sometimes hard-earned) lessons of a lifetime get lost when a person dies. Some lessons do survive through a child or someone with a specific interest but most go extinct, like a language no one speaks anymore. Culture and technology evolve, creating and destroying, creating and destroying. My mom made chicken this way, right down to the self-deprecating comments, as if everything were part of the same recipe. How many lessons and traditions disappear because no one makes an effort to learn them, and the world they came from no longer exists.]

It is nine at night on my last day in the South before my great-aunt Nancy and I start making fried chicken. The whole thing came about this way: Suddenly, after eating Nancy’s cake for cousin Judy’s birthday, I was filled with unaccountable remembrance of how, years ago, almost as a kind of ritual, my grandmother used to tell me that if I wanted to make good fried chicken I should ask Nancy. “You mean Alice,” Nancy corrects when I ask her to tell me about chicken. “Everyone knows Alice's was the best.”

Maybe they do in some parts. Nancy and Alice and Grandma were sisters. But I never knew Alice well, and she’s been dead a long time, and from what I remember, she might not have been the sort of person I’d approach on a whim to ask how to make fried chicken. But I do remember my grandmother telling me to ask Nancy. And so now, two years after my grandmother’s death, I’m here with Nancy in her fluorescent-lit ranch bungalow on Vickrey Chapel Road on my last day in Greensboro.

I’m headed back to California tomorrow. I have lived in California and Brooklyn and Boston, but except for a summer right after graduate school, I have never lived in the South. I am only a Southerner by means of having three of my four grandparents, and many aunts and uncles and cousins, rooted in the stretch between Richmond, Virginia, and Wilmington, North Carolina; by way of hearing family accents and cadences and stories. I am only a Southerner by way of blood and lore. And Nancy, my grandmother’s baby sister, is the only one of six siblings well enough to hold the legends of her generation. She’s also the last one who can whip up perfect pimento cheese or a mouthwatering strawberry pie. In asking her to teach me some cooking, I’ve surprised myself by wanting some of her South in me, the way I surprise myself by finding a drawl with these cousins, by saying ya’ll and laughing on the porch with them, by the way I hanker for ham biscuits as soon as I am in their presence. I’ve surprised myself by suddenly having a real earnest deep and truthful desire to know the ways of chicken frying.

As this request wells up within me, it feels at once ancestral and strange. I don’t actually eat fried chicken, certainly not store- or restaurant-bought fried chicken. I live in California, for heaven’s sake. I live in Berkeley. I eat lean grilled proteins with a side of organic asparagus; wild-caught black cod with quinoa; tofu with soba noodles. When I don’t want to cook, I go out for salmon and crab sushi wrapped in Meyer lemon. But frying a chicken seems like an ancestral art, like knowing how to make a pie crust or a green tomato chutney, both of which I pride myself on knowing how to do. Here in my great-aunt’s house, here in Greensboro, I want to heed my grandmother’s injunction.

FAQ: All About The New Google “Hummingbird” Algorithm

[ed. See also: SEO Changed Forever in 2013.]

Google has a new search algorithm, the system it uses to sort through all the information it has when you search and come back with answers. It’s called “Hummingbird” and below, what we know about it so far.

What’s a “search algorithm?”

That’s a technical term for what you can think of as a recipe that Google uses to sort through the billions of web pages and other information it has, in order to return what it believes are the best answers.

What’s “Hummingbird?”

It’s the name of the new search algorithm that Google is using, one that Google says should return better results.

So that “PageRank” algorithm is dead?

No. PageRank is one of over 200 major “ingredients” that go into the Hummingbird recipe. Hummingbird looks at PageRank — how important links to a page are deemed to be — along with other factors like whether Google believes a page is of good quality, the words used on it and many other things (see our Periodic Table Of SEO Success Factors for a better sense of some of these).

Why is it called Hummingbird?

Google told us the name come from being “precise and fast.”

When did Hummingbird start? Today?

Google started using Hummingbird about a month ago, it said. Google only announced the change today.

What does it mean that Hummingbird is now being used?

Think of a car built in the 1950s. It might have a great engine, but it might also be an engine that lacks things like fuel injection or be unable to use unleaded fuel. When Google switched to Hummingbird, it’s as if it dropped the old engine out of a car and put in a new one. It also did this so quickly that no one really noticed the switch.

When’s the last time Google replaced its algorithm this way?

Google struggled to recall when any type of major change like this last happened. In 2010, the “Caffeine Update” was a huge change. But that was also a change mostly meant to help Google better gather information (indexing) rather than sorting through the information. Google search chief Amit Singhal told me that perhaps 2001, when he first joined the company, was the last time the algorithm was so dramatically rewritten.

What about all these Penguin, Panda and other “updates” — haven’t those been changes to the algorithm?

Panda, Penguin and other updates were changes to parts of the old algorithm, but not an entire replacement of the whole. Think of it again like an engine. Those things were as if the engine received a new oil filter or had an improved pump put in. Hummingbird is a brand new engine, though it continues to use some of the same parts of the old, like Penguin and Panda.

The Other Side of the Story

Most of us have had one of those teachers. For one of my friends, it was the ninth grade biology instructor who inspired her to become a doctor; for another it was the art history teacher who introduced her to Rothko and a career as a museum curator. Details about those teachers’ classes almost never matter; they provide a different education, which outweighs the value of carefully composed lesson plans. Those teachers offer insight that has nothing to do with multiplication tables and nothing to do with grasping Shakespeare. Instead, they teach us the things we can’t find on Wikipedia or in textbooks. They teach us things that are real and genuine and valuable, things we have to learn about life, about people, and about ourselves. They show us the big stuff.

I had one of those teachers when I was fourteen. His name was Mr. Lehrer.*

Mr. Lehrer had just graduated from college when he stepped in as my middle school’s new eighth grade American history teacher, halfway through the school year. He was 23 years old, but his round, unblemished face made him look more like someone’s high school-aged brother than a grown-up with his own health insurance. Even without the Wrangler jeans and cowboy boots he would occasionally wear to school, Mr. Lehrer appeared inescapably unsophisticated. His wardrobe consisted of a country boy’s Sunday best: short-sleeve oxford shirts, pressed khaki pants, and brown round-toed shoes made of thermoplastic rubber. All of his slacks were oversized just enough to subvert whatever professional appearance he meant to convey, and his hair had a cowlick as prominent as his syrupy southern accent. Mr. Lehrer’s thin lips stayed sealed most of the time, but when he did speak the sound came not from vocal chords but from roots in the Texas Coastal Bend. He had the comportment of a farmhand, always equally proud and sheepish as he stood, stiff and silent, waiting to be told what to do.

Mr. Lehrer rarely gave orders, and few of my peers took him seriously. At any given moment, he could be found pleading for silence while students arranged their desks in uneven clusters to chat. We would gossip or paint our nails or dance to hip-hop as it buzzed through the speaker on someone’s T-Mobile Sidekick. The boys would turn daily assignments into paper airplanes while the girls made origami cranes and fortune-tellers, but no matter what shape the worksheets took they were neither completed nor handed in.

On the few occasions when Mr. Lehrer did attempt to enforce the rules, he would shout into the din of eighth grade chatter only to have his students ignore him. So, one day, he gave up and started to ignore us back. When the bell rang at the top of the hour each class period, Mr. Lehrer would seclude himself in a corner of the room and quietly read emails for the next 55 minutes. He looked less like a teacher and more like a disenchanted camp counselor, underpaid and trapped in a space too small for larger hopes.

Once Mr. Lehrer stopped trying to teach and started to condone our classroom debauchery, he became an object of fascination for my group of friends. Suddenly the new young teacher seemed interesting, or, at the very least, worth investigating. We began to surround his desk with our insipid adolescent babbling and our newly curvaceous bodies, asking him questions about his teenage years on his family’s farm or about his fiancée who worked as a nurse. We asked what it was like to grow up in a town with the population of our middle school, or if it was exciting to finally get a driver’s license, or how it felt to go to college and move away from home.

Shortly after my group of friends first invaded his corner, Mr. Lehrer warmed to us and began responding to our questions. He told us about the time he hit a deer while driving home down a dark dirt road, and he said that he moved to Houston for his fiancée even though his parents had raised him to detest city life. Eventually, Mr. Lehrer let us address him by his first name—Trace—and he allowed us to spend lunchtime every day in his classroom while he told us about his life. We sat perched on desktops while Mr. Lehrer talked, devouring our crustless PB&J sandwiches along with every word he said.

To us, Mr. Lehrer was omniscient: he had already written the chapter of his life that my friends and I were starting to scribble for ourselves. Tales about his teen adventures seemed novel and foreign and, yet, as if they might soon become our own—we just had to blow out one more round of birthday candles and open up our eyes. Mr. Lehrer represented the way boys would be when we got to the other side of high school, seemed to us like the kind of male friend we could expect to have one day, but who we were lucky to find so soon. We all liked Mr. Lehrer. Mr. Lehrer liked all of us.

But I could always tell he liked me the most.
