  • The fact that many of our self-protective delusions are built into the way the brain works is no justification for not trying to override them. Knowing how dissonance works helps us identify our own inclinations to perpetuate errors -- and protect ourselves from those who can’t.

  • at last, history has gotten into bed with psychological science, and it’s a happy match. History gives us the data of, in Barbara Tuchman’s splendid words, our march of folly -- repeated examples of human beings unable and unwilling to learn from mistakes, let alone to admit them. Cognitive science shows us why
  • Our brains, which have allowed us to travel into outer space, have a whole bunch of design flaws, which is why we have so much breathtaking bumbling here on Earth.

  • Of the many built-in biases in human thought, three have perhaps the greatest consequences for our own history and that of nations: the belief that we see things as they really are, rather than as we wish them to be; the belief that we are better, kinder, smarter, and more ethical than average; and the confirmation bias, which sees to it that we notice, remember, and accept information that confirms our beliefs -- and overlook, forget, and discount information that disconfirms our beliefs.
  • The great motivational theory that accommodates all of these biases is cognitive dissonance, developed by Leon Festinger in 1957 and further refined and transformed into a theory of self-justification by his student (and later my coauthor and friend) Elliot Aronson. The need to reduce dissonance is the key mechanism that underlies the reluctance to be wrong, to change our minds, to admit serious mistakes, and to be unwilling to accept unwelcome information
  • The greater the dissonance between who we are and the mistake we made or the cruelty we committed, the greater the need to justify the mistake, the crime, the villainy, instead of admitting and rectifying it

shared by carolinewren on 03 Jun 15 - No Cached
  • In a recent&nbsp;piece&nbsp;for National Geographic, Book Talk curator Simon Worrall entitled his headline, “In Age of Science, Is Religion 'Harmful Superstition'?” For the answer, he gave platform to Jerry Coyne, author of&nbsp;Faith vs. Fact: Why Science and Religion Are Incompatible.
  • Coyne, an atheist and University of Chicago professor of Ecology and Evolution, answered, among other questions, why “are religion and science incompatible.”
  • “[T]here are a number of things about evolution and science that undermine religion,” Coyne responded, including “the fact that the Genesis story is wrong.” “There’s no evidence that there’s any qualitatively different feature about humans from other species, except maybe for language” – language that “could have evolved via culture.”
  • ...12 more annotations...
  • “We’re not special products of&nbsp;God’s creation,” he concluded
  • As far as the “dualistic free will maintained by religions when they say you can choose to accept Jesus as your savior, or being homosexual is a choice,” Coyne decided, “Science is starting to undercut this, by showing that there’s only one choice we can make.”
  • “We are creatures of physics, made of molecules,” he persisted. “Therefore, our thoughts and behaviors are also the results of molecular motions.”
  • “[T]hey both compete to find truths about the universe,”
  • “Religion doesn’t have a methodology to weed out what’s false.” (And maybe that’s why it’s called faith.) “[I]t’s a way of fooling yourself,” he said, through “methods” of “authority, revelation, dogma, and indoctrination.”
  • religion is, as Coyne claims, “the most widespread and harmful form of superstition.”
  • “Since I see all religious belief as unfounded and irrational,” Coyne responded, “I consider religion to be superstition.”
  • “People get killed because they don’t share your beliefs.”
  • “The less a religion has to do with a tangible God, the less it hands out moral dictates and the better it is,” he pushed
  • (On a more legitimate note, Coyne then addressed the devastating story of Ashley King, who died after her parents decided to treat her bone cancer with prayer instead of medical treatment.)
  • “It doesn’t have anything to do with God,” he insisted. “It has to do with a commonality of feeling prompted by nature and the arts.

    A new species of ancient human has been unearthed in the Afar region of Ethiopia, scientists report. Researchers discovered jaw bones and teeth, which date to between 3.3m and 3.5m years old. It means this new hominin was alive at the same time as several other early human species, suggesting our family tree is more complicated than was thought.

  • Your new book, “Between the World and Me,” is a great and searing contribution to this public education. It is a mind-altering account of the black male experience. Every conscientious American should read it.
  • Written as a letter to your son, you talk about the effects of pervasive fear. “When I was your age the only people I knew were black and all of them were powerfully, adamantly, dangerously afraid.”
  • the disturbing challenge of your book is your rejection of the American dream. My ancestors chose to come here. For them, America was the antidote to the crushing restrictiveness of European life, to the pogroms. For them, the American dream was an uplifting spiritual creed that offered dignity, the chance to rise.
  • ...6 more annotations...
  • Your ancestors came in chains. In your book the dream of the comfortable suburban life is a “fairy tale.” For you, slavery is the original American sin, from which there is no redemption. America is Egypt without the possibility of the Exodus. African-American men are caught in a crushing logic, determined by the past, from which there is no escape.
  • The innocent world of the dream is actually built on the broken bodies of those kept down below.
  • I think you distort American history. This country, like each person in it, is a mixture of glory and shame. There’s a Lincoln for every Jefferson Davis and a Harlem Children’s Zone for every K.K.K. — and usually vastly more than one. Violence is embedded in America, but it is not close to the totality of America.
  • In your anger at the tone of innocence some people adopt to describe the American dream, you reject the dream itself as flimflam. But a dream sullied is not a lie. The American dream of equal opportunity, social mobility and ever more perfect democracy cherishes the future more than the past. It abandons old wrongs and transcends old sins for the sake of a better tomorrow.
  • This dream is a secular faith that has unified people across every known divide. It has unleashed ennobling energies and mobilized heroic social reform movements. By dissolving the dream under the acid of an excessive realism, you trap generations in the past and destroy the guiding star that points to a better future.
  • Ben.Lynch Augusta, Georgia 1 day ago I've followed Mr. Coates for sometime now and tend to agree with his viewpoints. As a white southern male who works in our segregated education systems, it took years for me to actually apprehend my day to day interactions with black children in poverty. For the longest time, I simply couldn't understand the behaviors I saw, the reactions, and at first I reacted with contempt, but then I began to understand little by little. I don't think I can express it to anyone here, let alone Mr. Brooks, but it is something that one only appears to get by letting it sink into your bones day after day, hour after hour. The conditions are terrible and promise to remain so for the rest of my career. My students know, even if they lack the rhetorical chops to express it, that the game is rigged, that what we sell, meaning America at large, to make ourselves feel better, to feel just, is demonstrably a false bill of goods that does nothing to solve the actual problems of their life. These students are so used to being crushed that they can't even begin to articulate that they are being crushed because it's simply how it is. Some suppose Mr. Coates is overly dour, overly negative, but he provides a necessary contrapuntal to those who assume that the arc of the universe inevitably bends toward justice. Struggle can and often does end in defeat. The wicked often sleep as well as the just and sometimes better. The sins of the fathers remain fixed around the necks of the sons and daughters.

Pain Really Is All In Your Head And Emotion Controls Intensity | WFSU - 0 views

shared by carolinewren on 09 Mar 15 - No Cached
  • When you whack yourself with a hammer, it feels like the pain is in your thumb. But really it's in your brain.
  • perception of pain is shaped by brain circuits that are constantly filtering the information coming from our sensory nerves,
  • In 2003, Turner was unloading supplies when his unit came under attack. He was wounded by a grenade. "He took shrapnel in his leg, in his side — and he didn't even notice that he had been hit,"
  • ...19 more annotations...
  • Despite his injuries, Turner began giving first aid and pulled other soldiers to safety. As he worked, he was shot twice — one bullet breaking a bone in his arm. Yet Turner would say later that he felt almost no pain.
  • "Soldiers in the heat of the moment don't recognize the pain that's happening," Linden says. But once that moment is over, those same soldiers may feel a lot of pain from something minor, like a hypodermic needle, he says.
  • brain also determines the emotion we attach to each painful experience, Linden says. That's possible, he explains, because the brain uses two different systems to process pain information coming from our nerve endings.
  • One system determines the pain's location, intensity and characteristics: stabbing, aching, burning, etc.
  • there is a completely separate system for the emotional aspect of pain
  • positive emotions — like feeling calm and safe and connected to others — can minimize pain. But negative emotions tend to have the opposite effect. Torturers have exploited that aspect for centuries.
  • they want to accentuate pain during torture they can do this with humiliation [or] with an unpredictable schedule of delivering pain
  • Those things will make the emotional component of the pain experience stronger."
  • CIA interrogators used both tactics after Sept. 11, according to a Senate report released late last year.
  • One thing scientists are still trying to understand is precisely how the brain regulates the perception of pain
  • The team studied low-frequency brain waves in a part of the brain that responds to sensations in the hand,
  • Earlier research had shown that these rhythms increase when the brain is blocking sensory information from the hand.
  • reseasrchers monitored the brain waves of a dozen people who were asked to pay attention only to their hand or only to their foot. During the experiment the scientists delivered a light tap to each person's finger or toe.
  • ocused on their feet, low-frequency rhythms increased in the brain area that responds to hand sensations — because participants were asking their brains to ignore sensory input from the hand, and it's these low-frequency rhythms that do the blocking of such information.
  • low-frequency rhythms also increased in a different brain area — the region that ignores distractions, the team discovered.
  • The two areas became synchronized
  • "There's coordination between the front part of the brain, which is the executive control region of the brain, and the sensory part of the brain, which is filtering information from the environment," she says.
  • suggests that at least some people can teach their brains how to filter out things like chronic pain, perhaps through meditation
  • It found that people who practiced mindfulness meditation for eight weeks greatly improved their control of the brain rhythms that block out pain.

  • I talked to a half-dozen of Hugh Moren’s fellow students. A highly indebted senior who was terrified of the weak job market described George Washington, where he had invested considerable time getting and doing internships, as “the world’s most expensive trade school.” Another mentioned the abundance of rich students whose parents were giving them a fancy-sounding diploma the way they might a new car. There are serious students here, he acknowledged, but: “You can go to G.W. and essentially buy a degree.”
  • A recent study from the Organization for Economic Cooperation and Development found that, on average, American college graduates score well below college graduates from most other industrialized countries in mathematics. In literacy (“understanding, evaluating, using and engaging with written text”), scores are just average. This comes on the heels of Richard Arum and Josipa Roksa’s “Academically Adrift,” a study that found “limited or no learning” among many college students.Instead of focusing on undergraduate learning, nu
  • colleges have been engaged in the kind of building spree I saw at George Washington. Recreation centers with world-class workout facilities and lazy rivers rise out of construction pits even as students and parents are handed staggeringly large tuition bills. Colleges compete to hire famous professors even as undergraduates wander through academic programs that often lack rigor or coherence. Campuses vie to become the next Harvard — or at least the next George Washington — while ignoring the growing cost and suspect quality of undergraduate education.
  • ...58 more annotations...
  • Mr. Trachtenberg understood the centrality of the university as a physical place. New structures were a visceral sign of progress. They told visitors, donors and civic leaders that the institution was, like beams and scaffolding rising from the earth, ascending. He added new programs, recruited more students, and followed the dictate of constant expansion.
  • the American research university had evolved into a complicated and somewhat peculiar organization. It was built to be all things to all people: to teach undergraduates, produce knowledge, socialize young men and women, train workers for jobs, anchor local economies, even put on weekend sports events. And excellence was defined by similarity to old, elite institutions. Universities were judged by the quality of their scholars, the size of their endowments, the beauty of their buildings and the test scores of their incoming students.
  • John Silber embarked on a huge building campaign while bringing luminaries like Saul Bellow and Elie Wiesel on board to teach and lend their prestige to the B.U. name, creating a bigger, more famous and much more costly institution. He had helped write a game plan for the aspiring college president.
  • GWU is, for all intents and purposes, a for-profit organization. Best example: study abroad. Their top program, a partnering with Sciences Po, costs each student (30 of them, on a program with 'prestige' status?) a full semester's tuition. It costs GW, according to Sciences Po website, €1000. A neat $20,000 profit per student (who is in digging her/himself deeper and deeper in debt.) Moreover, the school takes a $500 admin fee for the study abroad application! With no guarantee that all credits transfer. Students often lose a partial semester, GW profits again. Nor does GW offer help with an antiquated, one-shot/no transfers, tricky registration process. It's tough luck in gay Paris.Just one of many examples. Dorms with extreme mold, off-campus housing impossible for freshmen and sophomores. Required meal plan: Chick-o-Filet etc. Classes with over 300 students (required).This is not Harvard, but costs same.Emotional problems? Counselors too few. Suicides continue and are not appropriately addressed. Caring environment? Extension so and so, please hold.It's an impressive campus, I'm an alum. If you apply, make sure the DC experience is worth the price: good are internships, a few colleges like Elliot School, post-grad.GWU uses undergrad $$ directly for building projects, like the medical center to which students have NO access. (Student health facility is underfunded, outsourced.)Outstanding professors still make a difference. But is that enough?
  • Mr. Trachtenberg, however, understood something crucial about the modern university. It had come to inhabit a market for luxury goods. People don’t buy Gucci bags merely for their beauty and functionality. They buy them because other people will know they can afford the price of purchase. The great virtue of a luxury good, from the manufacturer’s standpoint, isn’t just that people will pay extra money for the feeling associated with a name brand. It’s that the high price is, in and of itself, a crucial part of what people are buying.
  • Mr. Trachtenberg convinced people that George Washington was worth a lot more money by charging a lot more money. Unlike most college presidents, he was surprisingly candid about his strategy. College is like vodka, he liked to explain.
  • The Absolut Rolex plan worked. The number of applicants surged from some 6,000 to 20,000, the average SAT score of students rose by nearly 200 points, and the endowment jumped from $200 million to almost $1 billion.
  • The university became a magnet for the children of new money who didn’t quite have the SATs or family connections required for admission to Stanford or Yale. It also aggressively recruited international students, rich families from Asia and the Middle East who believed, as nearly everyone did, that American universities were the best in the world.
  • U.S. News &amp; World Report now ranks the university at No. 54 nationwide, just outside the “first tier.”
  • The watch and vodka analogies are correct. Personally, I used car analogies when discussing college choices with my kids. We were in the fortunate position of being able to comfortably send our kids to any college in the country and have them leave debt free. Notwithstanding, I told them that they would be going to a state school unless they were able to get into one of about 40 schools that I felt, in whatever arbitrary manner I decided, that was worth the extra cost. They both ended up going to state schools.College is by and large a commodity and you get out of it what you put into it. Both of my kids worked hard in college and were involved in school life. They both left the schools better people and the schools better schools for them being there. They are both now successful adults.I believe too many people look for the prestige of a named school and that is not what college should be primarily about.
  • In 2013, only 14 percent of the university’s 10,000 undergraduates received a grant — a figure on a par with elite schools but far below the national average. The average undergraduate borrower leaves with about $30,800 in debt.
  • When I talk to the best high school students in my state I always stress the benefits of the honors college experience at an affordable public university. For students who won't qualify for a public honors college. the regular pubic university experience is far preferable to the huge debt of places like GW.
  • Carey would do well to look beyond high ticket private universities (which after all are still private enterprises) and what he describes as the Olympian heights of higher education (which for some reason seems also to embitter him) and look at the system overall . The withdrawal of public support was never a policy choice; it was a political choice, "packaged and branded" as some tax cutting palaver all wrapped up in the argument that a free-market should decide how much college should cost and how many seats we need. In such an environment, trustees at private universities are no more solely responsible for turning their degrees into commodities than the administrations of state universities are for raising the number of out-of-state students in order to offset the loss of support from their legislatures. No doubt, we will hear more about market based solutions and technology from Mr. Carey
  • I went to GW back in the 60s. It was affordable and it got me away from home in New York. While I was there, Newsweek famously published a article about the DC Universities - GW, Georgetown, American and Catholic - dubbing them the Pony league, the schools for the children of wealthy middle class New Yorkers who couldn't get into the Ivy League. Nobody really complained. But that wasn't me. I went because I wanted to be where the action was in the 60s, and as we used to say - "GW was literally a stone's throw from the White House. And we could prove it." Back then, the two biggest alumni names were Jackie Kennedy, who's taken some classes there, and J. Edgar Hoover. Now, according to the glossy magazine they send me each month, it's the actress Kerry Washington. There's some sort of progress there, but I'm a GW alum and not properly trained to understand it.
  • This explains a lot of the modern, emerging mentality. It encompasses the culture of enforced grade inflation, cheating and anti-intellectualism in much of higher education. It is consistent with our culture of misleading statistics and information, cronyism and fake quality, the "best and the brightest" being only schemers and glad handers. The wisdom and creativity engendered by an honest, rigorous academic education are replaced by the disingenuous quick fix, the winner-take-all mentality that neglects the common good.
  • I attended nearby Georgetown University and graduated in 1985. Relative to state schools and elite schools, it was expensive then. I took out loans. I had Pell grants. I had work-study and GSL. I paid my debt of $15,000 off in ten years. Would I have done it differently? Yes: I would have continued on to graduate school and not worried about paying off those big loans right after college. My career work out and I am grateful for the education I received and paid for. But I would not recommend to my nieces and nephews debts north of $100,000 for a BA in liberal arts. Go community. Then go state. Then punch your ticket to Harvard, Yale or Stanford — if you are good enough.
  • American universities appear to have more and more drifted away from educating individuals and citizens to becoming high priced trade schools and purveyors of occupational licenses. Lost in the process is the concept of expanding a student's ability to appreciate broadly and deeply, as well as the belief that a republican democracy needs an educated citizenry, not a trained citizenry, to function well.Both the Heisman Trophy winner and the producer of a successful tech I.P.O. likely have much in common, a college education whose rewards are limited to the financial. I don't know if I find this more sad on the individual level or more worrisome for the future of America.
  • This is now a consumer world for everything, including institutions once thought to float above the Shakespearean briars of the work-a-day world such as higher education, law and medicine. Students get this. Parents get this. Everything is negotiable: financial aid, a spot in the nicest dorm, tix to the big game. But through all this, there are faculty - lots of 'em - who work away from the fluff to link the ambitions of the students with the reality and rigor of the 21st century. The job of the student is to get beyond the visible hype of the surroundings and find those faculty members. They will make sure your investment is worth it
  • My experience in managing or working with GW alumni in their 20's or 30's has not been good. Virtually all have been mentally lazy and/or had a stunning sense of entitlement. Basically they've been all talk and no results. That's been quite a contrast to the graduates from VA/MD state universities.
  • More and more, I notice what my debt-financed contributions to the revenue streams of my vendors earn them, not me. My banks earned enough to pay ridiculous bonuses to employees for reckless risk-taking. My satellite tv operator earned enough to overpay ESPN for sports programming that I never watch--and that, in turn, overpays these idiotic pro athletes and college sports administrators. My health insurer earned enough to defeat one-payor insurance; to enable the opaque, inefficient billing practices of hospitals and other providers; and to feed the behemoth pharmaceutical industry. My church earned enough to buy the silence of sex abuse victims and oppose progressive political candidates. And my govt earned enough to continue ag subsidies, inefficient defense spending, and obsolete transportation and energy policies.
  • as the parent of GWU freshman I am grateful for every opportunity afforded her. She has a generous merit scholarship, is in the honors program with some small classes, and has access to internships that can be done while at school. GWU also gave her AP credits to advance her to sophomore status. Had she attended the state flagship school (where she was accepted into that exclusive honors program) she would have a great education but little else. It's not possible to do foreign affairs related internship far from D.C. or Manhattan. She went to a very competitive high school where for the one or two ivy league schools in which she was interested, she didn't have the same level of connections or wealth as many of her peers. Whether because of the Common Application or other factors, getting into a good school with financial help is difficult for a middle class student like my daughter who had a 4.0 GPA and 2300 on the SAT. She also worked after school.The bottom line - GWU offered more money than perceived "higher tier" universities, and brought tuition to almost that of our state school system. And by the way, I think she is also getting a very good education.
  • This article reinforces something I have learned during my daughter's college application process. Most students choose a school based on emotion (reputation) and not value. This luxury good analogy holds up.
  • The entire education problem can be solved by MOOCs lots and lots of them plus a few closely monitored tests and personal interviews with people. Of course many many people make MONEY off of our entirely inefficient way of "educating" -- are we even really doing that -- getting a degree does NOT mean one is actually educated
  • As a first-generation college graduate I entered GW ambitious but left saddled with debt, and crestfallen at the hard-hitting realization that my four undergraduate years were an aberration from what life is actually like post-college: not as simple as getting an [unpaid] internship with a fancy titled institution, as most Colonials do. I knew how to get in to college, but what do you do after the recess of life ends?I learned more about networking, resume plumping (designated responses to constituents...errr....replied to emails), and elevator pitches than actual theory, economic principles, strong writing skills, critical thinking, analysis, and philosophy. While relatively easy to get a job after graduating (for many with a GW degree this is sadly not the case) sustaining one and excelling in it is much harder. It's never enough just to be able to open a new door, you also need to be prepared to navigate your way through that next opportunity.
  • this is a very telling article. Aimless and directionless high school graduates are matched only by aimless and directionless institutes of higher learning. Each child and each parent should start with a goal - before handing over their hard earned tuition dollars, and/or leaving a trail of broken debt in the aftermath of a substandard, unfocused education.
  • it is no longer the most expensive university in America. It is the 46th.Others have been implementing the Absolut Rolex Plan. John Sexton turned New York University into a global higher-education player by selling the dream of downtown living to students raised on “Sex and the City.” Northeastern followed Boston University up the ladder. Under Steven B. Sample, the University of Southern California became a U.S. News top-25 university. Washington University in St. Louis did the same.
  • I currently attend GW, and I have to say, this article completely misrepresents the situation. I have yet to meet a single person who is paying the full $60k tuition - I myself am paying $30k, because the school gave me $30k in grants. As for the quality of education, Foreign Policy rated GW the #8 best school in the world for undergraduate education in international affairs, Princeton Review ranks it as one of the best schools for political science, and U.S. News ranks the law school #20. The author also ignores the role that an expanding research profile plays in growing a university's prestige and educational power.
  • And in hundreds of regional universities and community colleges, presidents and deans and department chairmen have watched this spectacle of ascension and said to themselves, “That could be me.” Agricultural schools and technical institutes are lobbying state legislatures for tuition increases and Ph.D. programs, fitness centers and arenas for sport. Presidents and boards are drawing up plans to raise tuition, recruit “better” students and add academic programs. They all want to go in one direction — up! — and they are all moving with a single vision of what they want to be.
  • this is the same playbook used by hospitals the past 30 years or so. It is how Hackensack Hospital became Hackensack Medical Center and McComb Hospital became Southwest Mississippi Regional Medical Center. No wonder the results have been the same in healthcare and higher education; both have priced themselves out of reach for average Americans.
  • a world where a college is rated not by the quality of its output, but instaed, by the quality of its inputs. A world where there is practically no work to be done by the administration because the college's reputation is made before the first class even begins! This is isanity! But this is the swill that the mammoth college marketing departments nationwide have shoved down America's throat. Colleges are ranked not by the quality of their graduates, but rather, by the test scores of their incoming students!
  • The Pew Foundation has been doing surveys on what students learn, how much homework they do, how much time they spend with professors etc. All good stuff to know before a student chooses a school. It is called the National Survey of Student Engagement (NSSE - called Nessy). It turns out that the higher ranked schools do NOT allow their information to be released to the public. It is SECRET.Why do you think that is?
  • The article blames "the standard university organizational model left teaching responsibilities to autonomous academic departments and individual faculty members, each of which taught and tested in its own way." This is the view of someone who has never taught at a university, nor thought much about how education there actually happens. Once undergraduates get beyond the general requirements, their educations _have_ to depend on "autonomous departments" because it's only those departments know what the requirements for given degree can be, and can grant the necessary accreditation of a given student. The idea that some administrator could know what's necessary for degrees in everything from engineering to fiction writing is nonsense, except that's what the people who only know the theory of education (but not its practice) actually seem to think. In the classroom itself, you have tremendously talented people, who nevertheless have their own particular strengths and approaches. Don't you think it's a good idea to let them do what they do best rather than trying to make everyone teach the same way? Don't you think supervision of young teachers by older colleagues, who actually know their field and its pedagogy, rather than some administrator, who knows nothing of the subject, is a good idea?
  • it makes me very sad to see how expensive some public schools have become. Used to be you could work your way through a public school without loans, but not any more. Like you, I had the advantage of a largely-scholarship paid undergraduate education at a top private college. However, I was also offered a virtually free spot in my state university's (then new) honors college
  • My daughter attended a good community college for a couple of classes during her senior year of high school and I could immediately see how such places are laboratories for failure. They seem like high schools in atmosphere and appearance. Students rush in by car and rush out again when the class is over.The four year residency college creates a completely different feel. On arrival, you get the sense that you are engaging in something important, something apart and one that will require your full attention. I don't say this is for everyone or that the model is not flawed in some ways (students actually only spend 2 1/2 yrs. on campus to get the four yr. degree). College is supposed to be a 60 hour per week job. Anything less than that and the student is seeking himself or herself
  • This. Is. STUNNING. I have always wondered, especially as my kids have approached college age, why American colleges have felt justified in raising tuition at a rate that has well exceeded inflation, year after year after year. (Nobody needs a dorm with luxury suites and a lazy river pool at college!) And as it turns out, they did it to become luxury brands. Just that simple. Incredible.I don't even blame this guy at GWU for doing what he did. He wasn't made responsible for all of American higher ed. But I do think we all need to realize what happened, and why. This is front page stuff.
  • I agree with you, but, unfortunately, given the choice between low tuition, primitive dorms, and no athletic center VS expensive &amp; luxurious, the customers (and their parents) are choosing the latter. As long as this is the case, there is little incentive to provide bare-bones and cheap education.
  • Wesleyan University in CT is one school that is moving down the rankings. Syracuse University is another. Reed College is a third. Why? Because these schools try hard to stay out of the marketing game. (With its new president, Syracuse has jumped back into the game.) Bryn Mawr College, outside Philadelphia hasn't fared well over the past few decades in the rankings, which is true of practically every women's college. Wellesley is by far the highest ranked women's college, but even there the acceptance rate is significantly higher than one finds at comparable coed liberal arts colleges like Amherst &amp; Williams. University of Chicago is another fascinating case for Mr. Carey to study (I'm sure he does in his forthcoming book, which I look forward to reading). Although it has always enjoyed an illustrious academic reputation, until recently Chicago's undergraduate reputation paled in comparison to peer institutions on the two coasts. A few years ago, Chicago changed its game plan to more closely resemble Harvard and Stanford in undergraduate amenities, and lo and behold, its rankings shot up. It was a very cynical move on the president's part to reassemble the football team, but it was a shrewd move because athletics draw more money than academics ever can (except at engineering schools like Cal Tech &amp; MIT), and more money draws richer students from fancier secondary schools with higher test scores, which lead to higher rankings - and the beat goes on.
  • College INDUSTRY is out of control. Sorry, NYU, GW, BU are not worth the price. Are state schools any better? We have the University of Michigan, which is really not a state school, but a university that gives a discount to people who live in Michigan. Why? When you have an undergraduate body 40+% out-of-state that pays tuition of over $50K/year, you tell me?Perhaps the solution is two years of community college followed by two at places like U of M or Michigan State - get the same diploma at the end for much less and beat the system.
  • In one recent yr., the majority of undergrad professors at Harvard, according to Boston.com, where adjuncts. That means low pay, no benefits, no office, temp workers. Harvard.Easily available student loans fueled this arms race of amenities and frills that in which colleges now engage. They moved the cost of education onto the backs of people, kids, who don't understand what they are doing.Students in colleges these days are customers and the customers must be able to get through. If it requires dumbing things down, so be it. On top of tuition, G.W. U. is known by its students as the land of added fees on top of added fees. The joke around campus was that they would soon be installing pay toilets in the student union. No one was laughing.
  • You could written the same story about my alma mater, American University. The place reeked of ambition and upward mobility decades ago and still does. Whoever's running it now must look at its measly half-billion-dollar endowment and compare it to GWU's $1.5 billion and seethe with envy, while GWU's president sets his sights on an Ivy League-size endowment. And both get back to their real jobs: 24/7 fundraising,Which is what university presidents are all about these days. Money - including million-dollar salaries for themselves (GWU's president made more than Harvard's in 2011) - pride, cachet, power, a mansion, first-class all the way. They should just be honest about it and change their university's motto to Ostende mihi pecuniam! (please excuse my questionable Latin)Whether the students are actually learning anything is up to them, I guess - if they do, it's thanks to the professors, adjuncts and the administrative staff, who do the actual work of educating and keep the school running.
  • When I was in HS (70s), many of my richer friends went to GW and I was then of the impression that GW was a 'good' school. As I age, I have come to realize that this place is just another façade to the emptiness that has become America. All too often are we faced with a dilemma: damned if we do, damned if we don't. Yep, 'education' has become a trap for all too many of our citizen.
  • I transferred to GWU from a state school. I am forever grateful that I did. I wanted to get a good rigorous education and go to one of the best International Affairs schools in the world. Even though the state school I went to was dirt-cheap, the education and the faculty was awful. I transferred to GW and was amazed at the professors at that university. An ambassador or a prominent IA scholar taught every class. GW is an expensive school, but that is the free market. If you want a good education you need to be willing to pay for it or join the military. I did the latter and my school was completely free with no debt and I received an amazing education. If young people aren't willing to make some sort of sacrifice to get ahead or just expect everything to be given to then our country is in a sad state.We need to stop blaming universities like GWU that strive to attract better students, better professors, and better infrastructure. They are doing what is expected in America, to better oneself.
  • "Whether the students are actually learning anything is up to them, I guess." How could it possibly be otherwise??? I am glad that you are willing to give credit to teachers and administrators, but it is not they who "do the actual work of educating." From this fallacy comes its corollary, that we should blame teachers first for "under-performing schools". This long-running show of scapegoating may suit the wallets and vanity of American parents, but it is utterly senseless. When, if ever, American culture stops reeking of arrogance, greed and anti-intellectualism, things may improve, and we may resume the habit of bothering to learn. Until then, nothing doing.
  • Universities sell knowledge and grade students on how much they have learned. Fundamentally, there is conflict of interest in thsi setup. Moreover, students who are poorly educated, even if they know this, will not criticize their school, because doing so would make it harder for them to have a career. As such, many problems with higher education remain unexposed to the public.
  • I've lectured and taught in at least five different countries in three continents and the shortest perusal of what goes on abroad would totally undermine most of these speculations. For one thing American universities are unique in their dedication to a broad based liberal arts type education. In France, Italy or Germany, for example, you select a major like mathematics or physics and then in your four years you will not take even one course in another subject. The amount of work that you do that is critically evaluated by an instructor is a tiny fraction of what is done in an American University. While half educated critics based on profoundly incomplete research write criticism like this Universities in Germany Italy, the Netherlands, South Korea and Japan as well as France have appointed committees and made studies to explain why the American system of higher education so drastically outperforms their own system. Elsewhere students do get a rather nice dose of general education but it ends in secondary school and it has the narrowness and formulaic quality that we would just normally associate with that. The character who wrote this article probably never set foot on a "campus" of the University of Paris or Rome
  • The university is part of a complex economic system and it is responding to the demands of that system. For example, students and parents choose universities that have beautiful campuses and buildings. So universities build beautiful campuses. State support of universities has greatly declined, and this decline in funding is the greatest cause of increased tuition. Therefore universities must compete for dollars and must build to attract students and parents. Also, universities are not ranked based on how they educate students -- that's difficult to measure so it is not measured. Instead universities are ranked on research publications. So while universities certainly put much effort into teaching, research has to have a priority in order for the university to survive. Also universities do not force students and parents to attend high price institutions. Reasonably priced state institutions and community colleges are available to every student. Community colleges have an advantage because they are funded by property taxes. Finally learning requires good teaching, but it also requires students that come to the university funded, prepared, and engaged. This often does not happen. Conclusion- universities have to participate in profile raising actions in order to survive. The day that funding is provided for college, ranking is based on education, and students choose campuses with simple buildings, then things will change at the university.
  • This is the inevitable result of privatizing higher education. In the not-so-distant past, we paid for great state universities through our taxes, not tuition. Then, the states shifted funding to prisons and the Federal government radically cut research support and the GI bill. Instead, today we expect universities to support themselves through tuition, and to the extent that we offered students support, it is through non-dischargeable loans. To make matters worse, the interest rates on those loans are far above the government's cost of funds -- so in effect the loans are an excise tax on education (most of which is used to support a handful of for-profit institutions that account for the most student defaults). This "consumer sovereignty" privatized model of funding education works no better than privatizing California's electrical system did in the era of Enron, or our privatized funding of medical service, or our increasingly privatized prison system: it drives up costs at the same time that it replace quality with marketing.
  • There are data in some instances on student learning, but the deeper problem, as I suspect the author already knows, is that there is nothing like a consensus on how to measure that learning, or even on when is the proper end point to emphasize (a lot of what I teach -- I know this from what students have told me -- tends to come into sharp focus years after graduation).
  • Michael (Baltimore) has hit the nail on the head. Universities are increasingly corporatized institutions in the credentialing business. Knowledge, for those few who care about it (often not those paying for the credentials) is available freely because there's no profit in it. Like many corporate entities, it is increasingly run by increasingly highly paid administrators, not faculty.
  • GWU has not defined itself in any unique way, it has merely embraced the bland, but very expensive, accoutrements of American private education: luxury dorms, food courts, spa-like gyms, endless extracurricular activities, etc. But the real culprit for this bloat that students have to bear financially is the college ranking system by US News, Princeton Review, etc. An ultimately meaningless exercise in competition that has nevertheless pushed colleges and universities to be more like one another. A sad state of affairs, and an extremely expensive one for students
  • It is long past time to realize the failure of the Reagonomics-neoliberal private profits over public good program. In education, we need to return to public institutions publicly funded. Just as we need to recognize that Medicare, Social Security, the post office, public utilities, fire departments, interstate highway system, Veterans Administration hospitals and the GI bill are models to be improved and expanded, not destroyed.
  • George Washington is actually not a Rolex watch, it is a counterfeit Rolex. The real Rolexes of higher education -- places like Hopkins, Georgetown, Duke, the Ivies etc. -- have real endowments and real financial aid. No middle class kid is required to borrow $100,000 to get a degree from those schools, because they offer generous need-based financial aid in the form of grants, not loans. The tuition at the real Rolexes is really a sticker price that only the wealthy pay -- everybody else on a sliding scale. For middle class kids who are fortunate enough to get in, Penn actually ends up costing considerably less than a state university.The fake Rolexes -- BU, NYU, Drexel in Philadelphia -- don't have the sliding scale. They bury middle class students in debt.And really, though it is foolish to borrow $100,000 or $120,000 for an undergraduate degree, I don't find the transaction morally wrong. What is morally wrong is our federal government making that loan non-dischargeable in bankruptcy, so many if these kids will be having their wages garnished for the REST OF THEIR LIVES.There is a very simple solution to this, by the way. Cap the amount of non-dischargeable student loan debt at, say, $50,000
  • The slant of this article is critical of the growth of research universities. Couldn't disagree more. Modern research universities create are incredibly engines of economic opportunity not only for the students (who pay the bills) but also for the community via the creation of blue and white collar jobs. Large research university employ tens of thousands of locals from custodial and food service workers right up to high level administrators and specialist in finance, computer services, buildings and facilities management, etc. Johns Hopkins University and the University of Maryland system employ more people than any other industry in Maryland -- including the government. Research universities typically have hospitals providing cutting-edge medical care to the community. Local business (from cafes to property rental companies) benefit from a built-in, long-term client base as well as an educated workforce. And of course they are the foundry of new knowledge which is critical for the future growth of our country.Check out the work of famed economist Dr. Julia Lane on modeling the economic value of the research university. In a nutshell, there are few better investments America can make in herself than research universities. We are the envy of the world in that regard -- and with good reason. How many *industries* (let alone jobs) have Stanford University alone catalyzed?
  • What universities have the monopoly on is the credential. Anyone can learn, from books, from free lectures on the internet, from this newspaper, etc. But only universities can endow you with the cherished degree. For some reason, people are will to pay more for one of these pieces of paper with a certain name on it -- Ivy League, Stanford, even GW -- than another -- Generic State U -- though there is no evidence one is actually worth more in the marketplace of reality than the other. But, by the laws of economics, these places are actually underpriced: after all, something like 20 times more people are trying to buy a Harvard education than are allowed to purchase one. Usually that means you raise your price.
  • Overalll a good article, except for - "This comes on the heels of Richard Arum and Josipa Roksa’s “Academically Adrift,” a study that found “limited or no learning” among many college students." The measure of learning you report was a general thinking skills exam. That's not a good measure of college gains. Most psychologists and cognitive scientists worth their salt would tell you that improvement in critical thinking skills is going to be limited to specific areas. In other words, learning critical thinking skills in math will make little change in critical thinking about political science or biology. Thus we should not expect huge improvements in general critical thinking skills, but rather improvements in a student's major and other areas of focus, such as a minor. Although who has time for a minor when it is universally acknowledged that the purpose of a university is to please and profit an employer or, if one is lucky, an investor. Finally, improved critical thinking skills are not the end all and be all of a college education even given this profit centered perspective. Learning and mastering the cumulative knowledge of past generations is arguably the most important thing to be gained, and most universities still tend to excel at that even with the increasing mandate to run education like a business and cultivate and cull the college "consumer".
  • As for community colleges, there was an article in the Times several years ago that said it much better than I could have said it myself: community colleges are places where dreams are put on hold. Without making the full commitment to study, without leaving the home environment, many, if not most, community college students are caught betwixt and between, trying to balance work responsibilities, caring for a young child or baby and attending classes. For males, the classic "end of the road" in community college is to get a car, a job and a girlfriend, one who is not in college, and that is the end of the dream. Some can make it, but most cannot.
  • as a scientist I disagree with the claim that undergrad tuition subsidizes basic research. Nearly all lab equipment and research personnel (grad students, technicians, anyone with the title "research scientist" or similar) on campus is paid for through federal grants. Professors often spend all their time outside teaching and administration writing grant proposals, as the limited federal grant funds mean ~%85 of proposals must be rejected. What is more, out of each successful grant the university levies a "tax", called "overhead", of 30-40%, nominally to pay for basic operations (utilities, office space, administrators). So in fact one might say research helps fund the university rather than the other way around. Flag
  • It's certainly overrated as a research and graduate level university. Whether it is good for getting an undergraduate education is unclear, but a big part of the appeal is getting to live in D.C..while attending college instead of living in some small college town in the corn fields.

  • When she was a young physician, Dr. Martha Gulati noticed that many of her mentors were prescribing vitamin E and folic acid to patients. Preliminary studies in the early 1990s had linked both supplements to a lower risk of heart disease.She urged her father to pop the pills as well: “Dad, you should be on these vitamins, because every cardiologist is taking them or putting their patients on [them],” recalled Dr. Gulati, now chief of cardiology for the University of Arizona College of Medicine-Phoenix
  • But just a few years later, she found herself reversing course, after rigorous clinical trials found neither vitamin E nor folic acid supplements did anything to protect the heart. Even worse, studies linked high-dose vitamin E to a higher risk of heart failure, prostate cancer and death from any cause.
  • More than half of Americans take vitamin supplements, including 68 percent of those age 65 and older, according to a 2013 Gallup poll. Among older adults, 29 percent take four or more supplements of any kind
  • ...20 more annotations...
  • Often, preliminary studies fuel irrational exuberance about a promising dietary supplement, leading millions of people to buy in to the trend. Many never stop. They continue even though more rigorous studies — which can take many years to complete — almost never find that vitamins prevent disease, and in some cases cause harm
  • There’s no conclusive evidence that dietary supplements prevent chronic disease in the average American, Dr. Manson said. And while a handful of vitamin and mineral studies have had positive results, those findings haven’t been strong enough to recommend supplements to the general American public, she said.
  • The National Institutes of Health has spent more than $2.4 billion since 1999 studying vitamins and minerals. Yet for “all the research we’ve done, we don’t have much to show for it,” said Dr. Barnett Kramer, director of cancer prevention at the National Cancer Institute.
  • A big part of the problem, Dr. Kramer said, could be that much nutrition research has been based on faulty assumptions, including the notion that people need more vitamins and minerals than a typical diet provides; that megadoses are always safe; and that scientists can boil down the benefits of vegetables like broccoli into a daily pill.
  • when researchers tried to deliver the key ingredients of a healthy diet in a capsule, Dr. Kramer said, those efforts nearly always failed.
  • It’s possible that the chemicals in the fruits and vegetables on your plate work together in ways that scientists don’t fully understand — and which can’t be replicated in a table
  • More important, perhaps, is that most Americans get plenty of the essentials, anyway. Although the Western diet has a lot of problems — too much sodium, sugar, saturated fat and calories, in general — it’s not short on vitamins
  • Without even realizing it, someone who eats a typical lunch or breakfast “is essentially eating a multivitamin,”
  • The body naturally regulates the levels of many nutrients, such as vitamin C and many B vitamins, Dr. Kramer said, by excreting what it doesn’t need in urine. He added: “It’s hard to avoid getting the full range of vitamins.”
  • Not all experts agree. Dr. Walter Willett, a professor at the Harvard T.H. Chan School of Public Health, says it’s reasonable to take a daily multivitamin “for insurance.” Dr. Willett said that clinical trials underestimate supplements’ true benefits because they aren’t long enough, often lasting five to 10 years. It could take decades to notice a lower rate of cancer or heart disease in vitamin taker
  • For Charlsa Bentley, 67, keeping up with the latest nutrition research can be frustrating. She stopped taking calcium, for example, after studies found it doesn’t protect against bone fractures. Additional studies suggest that calcium supplements increase the risk of kidney stones and heart disease.
  • People who take vitamins tend to be healthier, wealthier and better educated than those who don’t, Dr. Kramer said. They are probably less likely to succumb to heart disease or cancer, whether they take supplements or not. That can skew research results, making vitamin pills seem more effective than they really are
  • Because folic acid can lower homocysteine levels, researchers once hoped that folic acid supplements would prevent heart attacks and strokes.In a series of clinical trials, folic acid pills lowered homocysteine levels but had no overall benefit for heart disease, Dr. Lichtenstein said
  • When studies of large populations showed that people who eat lots of seafood had fewer heart attacks, many assumed that the benefits came from the omega-3 fatty acids in fish oil, Dr. Lichtenstein said.Rigorous studies have failed to show that fish oil supplements prevent heart attacks
  • But it’s possible the benefits of sardines and salmon have nothing to do with fish oil, Dr. Lichtenstein said. People who have fish for dinner may be healthier as a result of what they don’t eat, such as meatloaf and cheeseburgers.
  • “Eating fish is probably a good thing, but we haven’t been able to show that taking fish oil [supplements] does anything for you,
  • In the tiny amounts provided by fruits and vegetables, beta carotene and similar substances appear to protect the body from a process called oxidation, which damages healthy cells, said Dr. Edgar Miller, a professor of medicine at Johns Hopkins School of Medicine.Experts were shocked when two large, well-designed studies in the 1990s found that beta carotene pills actually increased lung cancer rates.
  • Likewise, a clinical trial published in 2011 found that vitamin E, also an antioxidant, increased the risk of prostate cancer in men by 17 percent
  • “Vitamins are not inert,” said Dr. Eric Klein, a prostate cancer expert at the Cleveland Clinic who led the vitamin E study. “They are biologically active agents. We have to think of them in the same way as drugs. If you take too high a dose of them, they cause side effects.”
  • “We should be responsible physicians,” she said, “and wait for the data.”

Sex, Morality, and Modernity: Can Immanuel Kant Unite Us? - The Atlantic - 1 views

sexual abuse ethics sexual ethics morality discourse kant consent condemnation hookup golden rule psychology

  • Before I jump back into the conversation about sexual ethics that has unfolded on the Web in recent days, inspired by Emily Witt's n+1 essay "What Do You Desire?" and featuring a fair number of my favorite writers, it's worth saying a few words about why I so value debate on this subject, and my reasons for running through some sex-life hypotheticals near the end of this article.
  • As we think and live, the investment required to understand one another increases. So do the stakes of disagreeing. 18-year-olds on the cusp of leaving home for the first time may disagree profoundly about how best to live and flourish, but the disagreements are abstract. It is easy, at 18, to express profound disagreement with, say, a friend's notions of child-rearing. To do so when he's 28, married, and raising a son or daughter is delicate, and perhaps best avoided
  • I have been speaking of friends. The gulfs that separate strangers can be wider and more difficult to navigate because there is no history of love and mutual goodwill as a foundation for trust. Less investment has been made, so there is less incentive to persevere through the hard parts.
  • ...27 more annotations...
  • I've grown very close to new people whose perspectives are radically different than mine.
  • It floors me: These individuals are all repositories of wisdom. They've gleaned it from experiences I'll never have, assumptions I don't share, and brains wired different than mine. I want to learn what they know.
  • Does that get us anywhere? A little ways, I think.
  • "Are we stuck with a passé traditionalism on one hand, and total laissez-faire on the other?" Is there common ground shared by the orthodox-Christian sexual ethics of a Rod Dreher and those who treat consent as their lodestar?
  • Gobry suggests that Emmanuel Kant provides a framework everyone can and should embrace, wherein consent isn't nearly enough to make a sexual act moral--we must, in addition, treat the people in our sex lives as ends, not means.
  • Here's how Kant put it: "Act in such a way that you treat humanity, whether in your own person or in the person of any other, never merely as a means to an end, but always at the same time as an end."
  • the disappearance of a default sexual ethic in America and the divergence of our lived experiences means we have more to learn from one another than ever, even as our different choices raise the emotional stakes.
  • Nor does it seem intuitively obvious that a suffering, terminally ill 90-year-old is regarding himself as a means, or an object, if he prefers to end his life with a lethal injection rather than waiting three months in semi-lucid agony for his lungs to slowly shut down and suffocate him. (Kant thought suicide impermissible.) The terminally ill man isn't denigrating his own worth or the preciousness of life or saying it's permissible "any time" it is difficult. He believes ending his life is permissible only because the end is nigh, and the interim affords no opportunity for "living" in anything except a narrow biological sense.
  • It seems to me that, whether we're talking about a three-week college relationship or a 60-year marriage, it is equally possible to treat one's partner as a means or as an end (though I would agree that "treating as means" is more common in hookups than marriage)
  • my simple definition is this: It is wrong to treat human persons in such a way that they are reduced to objects. This says nothing about consent: a person may consent to be used as an object, but it is still wrong to use them that way. It says nothing about utility: society may approve of using some people as objects; whether those people are actual slaves or economically oppressed wage-slaves it is still wrong to treat them like objects. What it says, in fact, is that human beings have intrinsic worth and dignity such that treating them like objects is wrong.
  • what it means to treat someone as a means, or as an object, turns out to be in dispute.
  • Years ago, I interviewed a sister who was acting as a surrogate for a sibling who couldn't carry her own child. The notion that either regarded the other (or themselves) as an object seems preposterous to me. Neither was treating the other as a means, because they both freely chose, desired and worked in concert to achieve the same end.
  • It seems to me that the Kantian insight is exactly the sort of challenge traditionalist Christians should make to college students as they try to persuade them to look more critically at hookup culture. I think a lot of college students casually mislead one another about their intentions and degree of investment, feigning romantic interest when actually they just want to have sex. Some would say they're transgressing against consent. I think Kant has a more powerful challenge.&nbsp;
  • Ultimately, Kant only gets us a little way in this conversation because, outside the realm of sex, he thinks consent goes a long way toward mitigating the means problem, whereas in the realm of sex, not so much. This is inseparable from notions he has about sex that many of us just don't share.
  • two Biblical passages fit my moral intuition even better than Kant. "Love your neighbor as yourself." And "therefore all things whatsoever would that men should do to you, do ye even so to them.
  • "do unto others..." is extremely demanding, hard to live up to, and a very close fit with my moral intuitions.
  • "Do unto others" is also enough to condemn all sorts of porn, and to share all sorts of common ground with Dreher beyond consent. Interesting that it leaves us with so many disagreements too. "Do unto others" is core to my support for gay marriage.
  • Are our bones always to be trusted?) The sexual behavior parents would be mortified by is highly variable across time and cultures. So how can I regard it as a credible guide of inherent wrong? Professional football and championship boxing are every bit as violent and far more physically damaging to their participants than that basement scene, yet their cultural familiarity is such that most people don't feel them to be morally suspect. Lots of parents are proud, not mortified, when a son makes the NFL.
  • "Porn operates in fantasy the way boxing and football operate in fantasy. The injuries are quite real." He is, as you can see, uncomfortable with both. Forced at gunpoint to choose which of two events could proceed on a given night, an exact replica of the San Francisco porn shoot or an Ultimate Fighting Championship tournament--if I had to shut one down and grant the other permission to proceed--what would the correct choice be?
  • insofar as there is something morally objectionable here, it's that the audience is taking pleasure in the spectacle of someone being abused, whether that abuse is fact or convincing illusion. Violent sports and violent porn interact with dark impulses in humanity, as their producers well know.
  • If Princess Donna was failing to "do unto others" at all, the audience was arguably who she failed. Would she want others to entertain her by stoking her dark human impulses? Then again, perhaps she is helping to neuter and dissipate them in a harmless way. That's one theory of sports, isn't it? We go to war on the gridiron as a replacement for going to war? And the rise in violent porn has seemed to coincide with falling, not rising, incidence of sexual violence.&nbsp;
  • On all sorts of moral questions I can articulate confident judgments. But I am confident in neither my intellect nor my gut when it comes to judging Princess Donna, or whether others are transgressing against themselves or "nature" when doing things that I myself wouldn't want to do. Without understanding their mindset, why they find that thing desirable, or what it costs them, if anything, I am loath to declare that it's grounded in depravity or inherently immoral just because it triggers my disgust instinct, especially if the people involved articulate a plausible moral code that they are following, and it even passes a widely held standard like "do unto others."
  • Here's another way to put it. Asked to render moral judgments about sexual behaviors, there are some I would readily label as immoral. (Rape is an extreme example. Showing the topless photo your girlfriend sent to your best friend is a milder one.) But I often choose to hold back and error on the side of not rendering a definitive judgment, knowing that occasionally means I'll fail to label as unethical some things that actually turn out to be morally suspect.
  • Partly I take that approach because, unlike Dreher, I don't see any great value or urgency in the condemnations, and unlike Douthat, I worry more about wrongful stigma than lack of rightful stigmas
  • In a society where notions of sexual morality aren't coercively enforced by the church or the state, what purpose is condemnation serving?
  • People are great! Erring on the side of failing to condemn permits at least the possibility of people from all of these world views engaging in conversation with one another.
  • Dreher worries about the fact that, despite our discomfort, neither Witt nor I can bring ourselves to say that the sexual acts performed during the S.F. porn shoot were definitely wrong. Does that really matter? My interlocutors perhaps see a cost more clearly than me, as well they might. My bias is that just arguing around the fire is elevating.

  • around 50 percent of people in the United States take some form of “dietary supplement” product, and among the most common are B vitamins.
  • Worse than just a harmless waste of money, this usage could be actively dangerous. In an issue of the Journal of Clinical Oncology, published this week, researchers reported that taking vitamin B6 and B12 supplements in high doses (like those sold in many stores) appears to triple or almost quadruple some people’s risk of lung cancer.
  • Starting in 1998, researchers assigned 6,837 people with heart disease to take either B vitamins or a placebo.
  • ...5 more annotations...
  • . In 2009, the researchers reported in the Journal of the American Medical Association that taking high doses of vitamin B12 along with folic acid (technically vitamin B9) was associated with greater risk of cancer and all-cause mortality.
  • There are legitimate and important uses for B-vitamin supplements, but the emerging evidence suggests we’re best to treat them more like pharmaceuticals than like panaceas to be shoveled into us in pursuit of energy, metabolic fortitude, “cardioprotection,” “bone wellness,” or whatever way in which we’d like to be better.
  • The research team is quick to note that the doses of B vitamins in question are enormous. The U.S. Recommended Dietary Allowance for B6 is 1.7 milligrams per day, and for B12 it’s 2.4 micrograms. The high-risk group in the study was taking around 20 times these amounts.That could seem nonsensical, except that these are the doses for sale at healthy-seeming places like Whole Foods and GNC. Many sellers offer daily 100-milligram B6 pills. B12 is available in doses of 5,000 micrograms.
  • Lung-cancer risk among men who took 20 milligrams of B6 daily for years was twice that of men who didn’t. Among people who smoke, the effect appeared to be synergistic, with B6 usage increasing risk threefold. The risk was even worse among smokers taking B12. Using more than 55 micrograms daily appeared to almost quadruple lung-cancer risk.
  • The current law gives consumers no reason to expect that risks will be listed on the labels of these products, or that health claims are accurate. A product like a high-dose B6 and B12 supplement hits shelves, and only decades later do researchers begin to understand the long-term health effects, who might benefit from taking it, and who might be harmed. &nbsp;

  • From 2008 to 2020, the average speeds of all major league baseball pitches combined rose by between 1.5 mph and 2 mph.
  • But MLB pitchers aren’t the only expert throwers; most healthy people can throw faster than our much stronger chimpanzee relatives, who max out at around 30 mph. A study of boys from the ages of 8 to 14 who were only moderately trained in throwing could still throw two times faster than chimps.
  • Humans are the only species that can throw well enough to kill rivals and prey. Because throwing requires the highly coordinated and extraordinarily rapid movements of multiple body parts, there was likely a long history of selection favoring the evolution of expert throwing in our ancestors.
  • ...3 more annotations...
  • The Australopithecines, the relatively small-brained, bipedal ancestors of our genus that lived in Africa somewhere between 1 million and 4 million years ago, probably threw projectiles as well, since their hand bones hint at their ability to grip objects and throw them.
  • Once the ability to throw quickly and accurately became critical to success in combat and hunting, our male ancestors would have been more likely than females to develop, through natural selection, these skills, since anthropologists have shown that males tended to fight and hunt big game.
  • Sex differences in throwing do not exist just because males are, on average, larger and stronger. The relative size, shape and orientation of the shoulders of men increase the range of motion of the arm during the cocking phase, which facilitates better throwing.

  • In her historical novel, “Libertie,” she focuses on a Black woman who doesn’t yearn to be the first or only one of anything.
  • ...23 more annotations...
  • Kaitlyn Greenidge learned about the first Black woman to become a doctor in New York. “I filed it away and thought, if I ever got a chance to write a novel, I would want it to be about this,” she said.
  • Libertie, the rebellious heroine of Kaitlyn Greenidge’s new novel, comes from an extraordinary family, but longs to be ordinary.
  • As a young Black woman growing up in Reconstruction-era Brooklyn, Libertie is expected to follow in the footsteps of her trailblazing mother, a doctor who founded a women’s clinic.
  • “So much of Black history is focused on exceptional people,”
  • I wanted to explore is, what’s the emotional and psychological toll of being an exception, of being exceptional, and also, what about the people who just want to have a regular life and find freedom and achievement in being able to live in peace with their family — which is what Libertie wants?”
  • “If you come from a marginalized community, one of the ways you are marginalized is people telling you that you don’t have any history, or that your history is somehow diminished, or it’s very flat, or it’s not somehow as rich as the dominant history.”
  • “That idea of being the first and the only was a big piece of our experience,”
  • They are engaged in ongoing conversations about their writing, though they draw the line at reading and editing drafts of one another’s work.

  • “I’ve always been interested in the histories of things that are lesser known,”
  • “There’s a really powerful lyricism that feels new in this voice,”
  • Greenidge and her sisters developed a reverence for storytelling and history early on, when their parents and grandparents would tell stories about their ancestors and what life was like during the civil rights movement.
  • “That fracture was really formative for me,” she said. “It made me hyper aware of inequality and the doublespeak that goes on in America around the American dream and American exceptionalism, because that was proven to me not to be true.”
  • Greenidge was collecting stories from people whose ancestors had lived there, and tracked down a woman named Ellen Holly, who was the first Black actress to have a lead, recurring role on daytime TV, in “One Life to Live.”
  • Greenidge filed the family’s saga away in her mind, thinking she had the premise for a novel. When she got a writing fellowship, she was able to quit her side jobs and immerse herself in the research the novel required.
  • The resulting story feels both epic and intimate. As she reimagined the lives of the doctor and her daughter, Greenidge wove in other historical figures and events.
  • In one horrific scene, Libertie and her mother tend to Black families who fled Manhattan during the New York City draft riots.
  • Greenidge also drew on her own family history, and her experience of being a new mother.
  • Her daughter, Mavis, was born days after she finished a second draft of the book, and is now 18 months old. She finished revisions while living in a multigenerational household with her own mother and sisters.

Pfizer and Moderna Vaccines Likely to Produce Lasting Immunity, Study Finds - The New Y... - 0 views

immunity study Covid-19 vaccine

  • in people who survived Covid-19, immune cells that recognize the virus lie quiescent in the bone marrow for at least eight months after infection. A study by another team indicated that so-called memory B cells continue to mature and strengthen for at least a year after infection.
  • Based on those findings, researchers suggested that immunity might last for years, possibly a lifetime, in people who were infected with the coronavirus and later vaccinated.
  • But it was unclear whether vaccination alone might have a similarly long-lasting effect.
  • ...13 more annotations...
  • “Usually by four to six weeks, there’s not much left,” said Deepta Bhattacharya, an immunologist at the University of Arizona. But germinal centers stimulated by the mRNA vaccines are “still going, months into it, and not a lot of decline in most people.”
  • The broader the range and the longer these cells have to practice, the more likely they are to be able to thwart variants of the virus that may emerge.
  • “Everyone always focuses on the virus evolving — this is showing that the B cells are doing the same thing,” said Marion Pepper, an immunologist at the University of Washington in Seattle. “And it’s going to be protective against ongoing evolution of the virus, which is really encouraging.”
  • Dr. Ellebedy’s team found that 15 weeks after the first dose of vaccine, the germinal center was still highly active in all 14 of the participants, and that the number of memory cells that recognized the coronavirus had not declined.
  • “The fact that the reactions continued for almost four months after vaccination — that’s a very, very good sign,” Dr. Ellebedy said. Germinal centers typically peak one to two weeks after immunization, and then wane.
  • After an infection or a vaccination, a specialized structure called the germinal center forms in lymph nodes. This structure is an elite school of sorts for B cells — a boot camp where they become increasingly sophisticated and learn to recognize a diverse set of viral genetic sequences.
  • The results suggest that a vast majority of vaccinated people will be protected over the long term — at least, against the existing coronavirus variants
  • But older adults, people with weak immune systems and those who take drugs that suppress immunity may need boosters; people who survived Covid-19 and were later immunized may never need them at all.
  • In the absence of variants that sidestep immunity, in theory immunity could last a lifetime, experts said. But the virus is clearly evolving.
  • “Anything that would actually require a booster would be variant-based, not based on waning of immunity,” Dr. Bhattacharya said. “I just don’t see that happening.”
  • The good news: A booster vaccine will probably have the same effect as prior infection in immunized people, Dr. Ellebedy said. “If you give them another chance to engage, they will have a massive response,” he said, referring to memory B cells.
  • Dr. Ellebedy said the results also suggested that these signs of persistent immune reaction might be caused by mRNA vaccines alone, as opposed to those made by more traditional means, like Johnson &amp; Johnson’s
  • But that is an unfair comparison, because the Johnson &amp; Johnson vaccine is given as a single dose, Dr. Iwasaki said: “If the J &amp; J had a booster, maybe it will induce this same kind of response.”

  • Before the advent of Caribbean genetic studies, archaeologists provided most of the clues about the origins of people in the region. The first human residents of the Caribbean appear to have lived mostly as hunter-gatherers, catching game on the islands and fishing at sea while also maintaining small gardens of crops.
  • Archaeologists have discovered a few burials of those ancient people. Starting in the early 2000s, geneticists managed to fish out a few tiny bits of preserved DNA in their bones. Significant advances in recent years have made it possible to pull entire genomes from ancient skeletons.
  • “We went from zero full genomes two years ago to over 200 now,”
  • ...17 more annotations...
  • The genes of the oldest known residents of the Caribbean link them with the earliest populations that settled in Central and South America.
  • Part of the problem is that scientists have yet to find ancient DNA in the Caribbean that is more than 3,000 years old
  • The other problem is that ancient DNA is still scarce on the Caribbean coast of the mainland.
  • About 2,500 years ago, the archaeological record shows, there was a drastic shift in the cultural life of the Caribbean. People started living in bigger settlements, intensively farming crops like maize and sweet potatoes. Their pottery became more sophisticated and elaborate. For archaeologists, the change indicates the end of what they call the Archaic Age and the start of a Ceramic Age.
  • The skeletons from the Ceramic Age largely shared a new genetic signature. Their DNA links them to small tribes still living today in Colombia and Venezuela.
  • We don’t know a lot about these languages, although some words have managed to survive. Hurricane, for example, comes from hurakán, the Taino name for the god of storms.
  • The people bearing Ceramic Age ancestry came to dominate the Caribbean, with almost no interbreeding between the two groups.
  • These words bear a striking resemblance to words from a family of languages in South America called Arawak. The DNA of the Ceramic Age Caribbeans most closely resembles that of living Arawak speakers.
  • the new DNA findings had surprised him in many ways, giving him a host of new questions to investigate.
  • Over the course of the Ceramic Age, for example, strikingly new pottery styles emerged every few centuries. Researchers have long guessed that those shifts reflect the arrival of new groups of people in the islands. The ancient DNA doesn’t support that idea, though. There’s a genetic continuity through those drastic cultural changes. It appears that the same group of people in the Caribbean went through a series of major social changes that archaeologists have yet to explain.
  • Dr. Reich and his fellow geneticists also discovered family ties that spanned the Caribbean during the Ceramic Age. They found 19 pairs of people on different islands who shared identical segments of DNA — a sign that they were fairly close relatives. In one case, they found long-distance cousins from the Bahamas and Puerto Rico, separated by over 800 miles.
  • “The original idea was that people start in one place, they establish a colony someplace else, and then they just cut all ties to where they came from,” Dr. Keegan said. “But the genetic evidence is suggesting that these ties were maintained over a long period of time.”
  • Rather than being made up of isolated communities, in other words, the Caribbean was a busy, long-distance network that people regularly traveled by dugout canoe. “The water is like a highway,”
  • The genetic variations also allowed Dr. Reich and his colleague to estimate the size of the Caribbean society before European contact. Christopher Columbus’s brother Bartholomew sent letters back to Spain putting the figure in the millions
  • The DNA suggests that was an exaggeration: the genetic variations imply that the total population was as low as the tens of thousands.
  • now, with a population of about 44 million people, the Caribbean may contain more Taino DNA than it did in 1491.
  • Dr. Aviles and his colleagues have uploaded the ancient Caribbean genomes to a genealogical database called GEDMatch. With the help of genealogists, people can compare their own DNA to the ancient genomes. They can see the matching stretches of genetic material that reveal their relatedness.

  • The human brain is more complex than any other known structure in the universe.
  • Weighing in at three pounds, on average, this spongy mass of fat and protein is made up of two overarching types of cells—called glia and neurons—and it contains many billions of each.
  • The cerebrum is the largest part of the brain, accounting for 85 percent of the organ's weight. The distinctive, deeply wrinkled outer surface is the cerebral cortex. It's the cerebrum that makes the human brain—and therefore humans—so formidable. Animals such as elephants, dolphins, and whales actually have larger brains, but humans have the most developed cerebrum. It's packed to capacity inside our skulls, with deep folds that cleverly maximize the total surface area of the cortex.

  • The cerebrum has two halves, or hemispheres, that are further divided into four regions, or lobes. The frontal lobes, located behind the forehead, are involved with speech, thought, learning, emotion, and movement.
  • Behind them are the parietal lobes, which process sensory information such as touch, temperature, and pain.
  • At the rear of the brain are the occipital lobes, dealing with vision
  • Lastly, there are the temporal lobes, near the temples, which are involved with hearing and memory.
  • The second-largest part of the brain is the cerebellum, which sits beneath the back of the cerebrum.

  • Want more proof that the brain is extraordinary? Look no further than the blood-brain barrier.
  • This led scientists to learn that the brain has an ingenious, protective layer. Called the blood-brain barrier, it’s made up of special, tightly bound cells that together function as a kind of semi-permeable gate throughout most of the organ. It keeps the brain environment safe and stable by preventing some toxins, pathogens, and other harmful substances from entering the brain through the bloodstream, while simultaneously allowing oxygen and vital nutrients to pass through.
  • One in five Americans suffers from some form of neurological damage, a wide-ranging list that includes stroke, epilepsy, and cerebral palsy, as well as dementia.

  • Unfortunately, negative attitudes toward people who suffer from mental illness are widespread. The stigma attached to mental illness can create feelings of shame, embarrassment, and rejection, causing many people to suffer in silence.
  • In the United States, where anxiety disorders are the most common forms of mental illness, only about 40 percent of sufferers receive treatment. Anxiety disorders often stem from abnormalities in the brain’s hippocampus and prefrontal cortex.

  • Padilla laid out an indictment of his field. “If one were intentionally to design a discipline whose institutional organs and gatekeeping protocols were explicitly aimed at disavowing the legitimate status of scholars of color,” he said, “one could not do better than what classics has done.”
  • Padilla believes that classics is so entangled with white supremacy as to be inseparable from it. “Far from being extrinsic to the study of Greco-Roman antiquity,” he has written, “the production of whiteness turns on closer examination to reside in the very marrows of classics.”
  • Rather than kowtowing to criticism, Williams said, “maybe we should start defending our discipline.” She protested that it was imperative to stand up for the classics as the political, literary and philosophical foundation of European and American culture: “It’s Western civilization. It matters because it’s the West.” Hadn’t classics given us the concepts of liberty, equality and democracy?
  • ...46 more annotations...
  • Williams ceded the microphone, and Padilla was able to speak. “Here’s what I have to say about the vision of classics that you outlined,” he said. “I want nothing to do with it. I hope the field dies that you’ve outlined, and that it dies as swiftly as possible.”
  • “I believe in merit. I don’t look at the color of the author.” She pointed a finger in Padilla’s direction. “You may have got your job because you’re Black,” Williams said, “but I would prefer to think you got your job because of merit.”
  • What he did find was a slim blue-and-white textbook titled “How People Lived in Ancient Greece and Rome.” “Western civilization was formed from the union of early Greek wisdom and the highly organized legal minds of early Rome,” the book began. “The Greek belief in a person’s ability to use his powers of reason, coupled with Roman faith in military strength, produced a result that has come to us as a legacy, or gift from the past.” Thirty years later, Padilla can still recite those opening lines.
  • In 2017, he published a paper in the journal Classical Antiquity that compared evidence from antiquity and the Black Atlantic to draw a more coherent picture of the religious life of the Roman enslaved. “It will not do merely to adopt a pose of ‘righteous indignation’ at the distortions and gaps in the archive,” he wrote. “There are tools available for the effective recovery of the religious experiences of the enslaved, provided we work with these tools carefully and honestly.”
  • Padilla sensed that his pursuit of classics had displaced other parts of his identity, just as classics and “Western civilization” had displaced other cultures and forms of knowledge. Recovering them would be essential to dismantling the white-supremacist framework in which both he and classics had become trapped. “I had to actively engage in the decolonization of my mind,” he told me.
  • He also gravitated toward contemporary scholars like José Esteban Muñoz, Lorgia García Peña and Saidiya Hartman, who speak of race not as a physical fact but as a ghostly system o
  • In response to rising anti-immigrant sentiment in Europe and the United States, Mary Beard, perhaps the most famous classicist alive, wrote in The Wall Street Journal that the Romans “would have been puzzled by our modern problems with migration and asylum,” because the empire was founded on the “principles of incorporation and of the free movement of people.”
  • In November 2015, he wrote an essay for Eidolon, an online classics journal, clarifying that in Rome, as in the United States, paeans to multiculturalism coexisted with hatred of foreigners. Defending a client in court, Cicero argued that “denying foreigners access to our city is patently inhumane,” but ancient authors also recount the expulsions of whole “suspect” populations, including a roundup of Jews in 139 B.C., who were not considered “suitable enough to live alongside Romans.”
  • The job of classicists is not to “point out the howlers,” he said on a 2017 panel. “To simply take the position of the teacher, the qualified classicist who knows things and can point to these mistakes, is not sufficient.”
  • Dismantling structures of power that have been shored up by the classical tradition will require more than fact-checking; it will require writing an entirely new story about antiquity, and about who we are today
  • To find that story, Padilla is advocating reforms that would “explode the canon” and “overhaul the discipline from nuts to bolts,” including doing away with the label “classics” altogether.
  • . “What I want to be thinking about in the next few weeks,” he told them, “is how we can be telling the story of the early Roman Empire not just through a variety of sources but through a variety of persons.” He asked the students to consider the lives behind the identities he had assigned them, and the way those lives had been shaped by the machinery of empire, which, through military conquest, enslavement and trade, creates the conditions for the large-scale movement of human beings.
  • ultimately, he decided that leaving enslaved characters out of the role play was an act of care. “I’m not yet ready to turn to a student and say, ‘You are going to be a slave.’”
  • Privately, even some sympathetic classicists worry that Padilla’s approach will only hasten the field’s decline. “I’ve spoken to undergrad majors who say that they feel ashamed to tell their friends they’re studying classics,”
  • “I very much admire Dan-el’s work, and like him, I deplore the lack of diversity in the classical profession,” Mary Beard told me via email. But “to ‘condemn’ classical culture would be as simplistic as to offer it unconditional admiration.”
  • In a 2019 talk, Beard argued that “although classics may become politicized, it doesn’t actually have a politics,” meaning that, like the Bible, the classical tradition is a language of authority — a vocabulary that can be used for good or ill by would-be emancipators and oppressors alike.
  • Over the centuries, classical civilization has acted as a model for people of many backgrounds, who turned it into a matrix through which they formed and debated ideas about beauty, ethics, power, nature, selfhood, citizenship and, of course, race
  • Anthony Grafton, the great Renaissance scholar, put it this way in his preface to “The Classical Tradition”: “An exhaustive exposition of the ways in which the world has defined itself with regard to Greco-Roman antiquity would be nothing less than a comprehensive history of the world.”
  • Classics as we know it today is a creation of the 18th and 19th centuries. During that period, as European universities emancipated themselves from the control of the church, the study of Greece and Rome gave the Continent its new, secular origin story. Greek and Latin writings emerged as a competitor to the Bible’s moral authority, which lent them a liberatory power
  • Historians stress that such ideas cannot be separated from the discourses of nationalism, colorism and progress that were taking shape during the modern colonial period, as Europeans came into contact with other peoples and their traditions. “The whiter the body is, the more beautiful it is,” Winkelmann wrote.
  • While Renaissance scholars were fascinated by the multiplicity of cultures in the ancient world, Enlightenment thinkers created a hierarchy with Greece and Rome, coded as white, on top, and everything else below.
  • Jefferson, along with most wealthy young men of his time, studied classics at college, where students often spent half their time reading and translating Greek and Roman texts. “Next to Christianity,” writes Caroline Winterer, a historian at Stanford, “the central intellectual project in America before the late 19th century was classicism.
  • Of the 2.5 million people living in America in 1776, perhaps only 3,000 had gone to college, but that number included many of the founders
  • They saw classical civilization as uniquely educative — a “lamp of experience,” in the words of Patrick Henry, that could light the path to a more perfect union. However true it was, subsequent generations would come to believe, as Hannah Arendt wrote in “On Revolution,” that “without the classical example … none of the men of the Revolution on either side of the Atlantic would have possessed the courage for what then turned out to be unprecedented action.”
  • Comparisons between the United States and the Roman Empire became popular as the country emerged as a global power. Even after Latin and Greek were struck from college-entrance exams, the proliferation of courses on “great books” and Western civilization, in which classical texts were read in translation, helped create a coherent national story after the shocks of industrialization and global warfare.
  • even as the classics were pulled apart, laughed at and transformed, they continued to form the raw material with which many artists shaped their visions of modernity.
  • Over the centuries, thinkers as disparate as John Adams and Simone Weil have likened classical antiquity to a mirror. Generations of intellectuals, among them feminist, queer and Black scholars, have seen something of themselves in classical texts, flashes of recognition that held a kind of liberatory promise
  • The language that is used to describe the presence of classical antiquity in the world today — the classical tradition, legacy or heritage — contains within it the idea of a special, quasi-genetic relationship. In his lecture “There Is No Such Thing as Western Civilization,” Kwame Anthony Appiah (this magazine’s Ethicist columnist) mockingly describes the belief in such a kinship as the belief in a “golden nugget” of insight — a precious birthright and shimmering sign of greatness — that white Americans and Europeans imagine has been passed down to them from the ancients.
  • To see classics the way Padilla sees it means breaking the mirror; it means condemning the classical legacy as one of the most harmful stories we’ve told ourselves
  • Padilla is wary of colleagues who cite the radical uses of classics as a way to forestall change; he believes that such examples have been outmatched by the field’s long alliance with the forces of dominance and oppression.
  • Classics and whiteness are the bones and sinew of the same body; they grew strong together, and they may have to die together. Classics deserves to survive only if it can become “a site of contestation” for the communities who have been denigrated by it in the past.
  • if classics fails his test, Padilla and others are ready to give it up. “I would get rid of classics altogether,” Walter Scheidel, another of Padilla’s former advisers at Stanford, told me. “I don’t think it should exist as an academic field.”
  • One way to get rid of classics would be to dissolve its faculties and reassign their members to history, archaeology and language departments.
  • many classicists are advocating softer approaches to reforming the discipline, placing the emphasis on expanding its borders. Schools including Howard and Emory have integrated classics with Ancient Mediterranean studies, turning to look across the sea at Egypt, Anatolia, the Levant and North Africa. The change is a declaration of purpose: to leave behind the hierarchies of the Enlightenment and to move back toward the Renaissance model of the ancient world as a place of diversity and mixture.
  • Ian Morris put it more bluntly. “Classics is a Euro-American foundation myth,” Morris said to me. “Do we really want that sort of thing?”
  • There’s a more interesting story to be told about the history of what we call the West, the history of humanity, without valorizing particular cultures in it,” said Josephine Quinn, a professor of ancient history at Oxford. “It seems to me the really crucial mover in history is always the relationship between people, between cultures.”
  • “In some moods, I feel that this is just a moment of despair, and people are trying to find significance even if it only comes from self-accusation,” he told me. “I’m not sure that there is a discipline that is exempt from the fact that it is part of the history of this country. How distinctly wicked is classics? I don’t know that it is.”
  • “One of the dubious successes of my generation is that it did break the canon,” Richlin told me. “I don’t think we could believe at the time that we would be putting ourselves out of business, but we did.” She added: “If they blew up the classics departments, that would really be the end.”
  • Padilla, like Douglass, now sees the moment of absorption into the classical, literary tradition as simultaneous with his apprehension of racial difference; he can no longer find pride or comfort in having used it to bring himself out of poverty.
  • “Claiming dignity within this system of structural oppression,” Padilla has said, “requires full buy-in into its logic of valuation.” He refuses to “praise the architects of that trauma as having done right by you at the end.”
  • Last June, as racial-justice protests unfolded across the nation, Padilla turned his attention to arenas beyond classics. He and his co-authors — the astrophysicist Jenny Greene, the literary theorist Andrew Cole and the poet Tracy K. Smith — began writing their open letter to Princeton with 48 proposals for reform. “Anti-Blackness is foundational to America,” the letter began. “Indifference to the effects of racism on this campus has allowed legitimate demands for institutional support and redress in the face of microaggression and outright racist incidents to go long unmet.”
  • Padilla believes that the uproar over free speech is misguided. “I don’t see things like free speech or the exchange of ideas as ends in themselves,” he told me. “I have to be honest about that. I see them as a means to the end of human flourishing.”
  • “There is a certain kind of classicist who will look on what transpired and say, ‘Oh, that’s not us,’” Padilla said when we spoke recently. “What is of interest to me is why is it so imperative for classicists of a certain stripe to make this discursive move? ‘This is not us.’
  • Joel Christensen, the Brandeis professor, now feels that it is his “moral and ethical and intellectual responsibility” to teach classics in a way that exposes its racist history. “Otherwise we’re just participating in propaganda,”
  • Christensen, who is 42, was in graduate school before he had his “crisis of faith,” and he understands the fear that many classicists may experience at being asked to rewrite the narrative of their life’s work. But, he warned, “that future is coming, with or without Dan-el.”
  • On Jan. 6, Padilla turned on the television minutes after the windows of the Capitol were broken. In the crowd, he saw a man in a Greek helmet with TRUMP 2020 painted in white. He saw a man in a T-shirt bearing a golden eagle on a fasces — symbols of Roman law and governance — below the logo 6MWE, which stands for “Six Million Wasn’t Enough,
