Truth, Lies, Politics, and the Press, in Three Acts - James Fallows - The Atlantic - 1 views

  • Both explain why the realities of modern "post-truth" politics will sooner or later force the press out of its preferred, comfortable pose of "balance," if it is to come close to doing its fundamental job of describing reality. When some people in public life are willing to lie, and to keep on lying even when the bald falseness is exposed, the press should take on an affirmative responsibility to remind readers what the "truth" is.
  • Some of the "savviest" and best-connected political journalists say that their duty is merely to recount the claims one side makes about the other, and whether or not they "work" in swinging votes. But, Rosen argues, a growing segment has concluded that "post-truth" politics requires reporters to do more than call play-by-play.
  • As a conservative myself politically, it annoys me no end to see deliberate lying and misinformation coming out where they will trash an outstanding American product and do damage to American employment just to get at Obama. That's just plain unethical.

Obesity: Another thing it's too late to prevent | The Economist - 0 views

  • It's not that it's impossible for governments to hold down obesity; France, which had rapidly rising childhood obesity early this century, instituted an aggressive set of public-health interventions including school-based food and exercise shifts, nurse assessments of overweight kids, visits to families where overweight kids were identified, and so forth. Their childhood obesity rates stabilised at a fraction of America's.
  • The problem isn't that it's not possible; rather, it's that America is incapable of doing it.
  • America's national governing ideology is based almost entirely on the assertion of negative rights, with a few exceptions for positive rights and public goods such as universal elementary education, national defence and highways. But it's become increasingly clear over the past decade that the country simply doesn't have the political vocabulary that would allow it to institute effective national programmes to improve eating and exercise habits or culture. A country that can't think of a vision of public life beyond freedom of individual choice, including the individual choice to watch TV and eat a Big Mac, is not going to be able to craft public policies that encourage people to exercise and eat right. We're the fattest country on earth because that's what our political philosophy leads to. We ought to incorporate that into the way we see ourselves; it's certainly the way other countries see us.

The Mind of a Flip-Flopper - NYTimes.com - 0 views

  • Moral attitudes are especially difficult to change, Haidt said, because the emotions attached to those preferences largely define who we are. “Certain beliefs are so important for a society or group that they become part of how you prove your identity,” he said. “It’s as though we circle around these ideas. It’s how we become one.”
  • We tend to side with people who share our identity — even when the facts disagree — and calling someone a flip-flopper is a way of calling them morally suspect
  • People change their minds all the time, even about very important matters. It’s just hard to do when the stakes are high. That’s why marshaling data and making rational arguments won’t work. Whether you’re changing your own mind or someone else’s, the key is emotional, persuasive storytelling.

  • Stories are more powerful than data, Wilson says, because they allow individuals to identify emotionally with ideas and people they might otherwise see as “outsiders.”
  • Once you care about a character, Wilson says, you can find a way to fit them into your identity.
  • Our identities, of course, are also stories we tell ourselves about ourselves. In some cases — if we want to think of ourselves as thoughtful and open-minded — we can adopt identities that actually encourage flip-flopping.
  • Simply having to articulate why you believe what you do can also end up changing your attitude
  • Even when we do change our minds, we often convince ourselves that we haven’t.
  • understanding the power of stories could go a long ways toward bridging gaps that only get bigger when we expect those who disagree to rationally accept data and evidence. “We fight it out by throwing arguments at each other and are upset when they have no effect,” Haidt says. “It makes us accuse our opponents of bad faith and ulterior motives. But the truth is that our minds just aren’t set up to be changed by mere evidence and argument presented by a ‘stranger.’ ”

Ryan, Romney and the Veil of Opulence - NYTimes.com - 0 views

  • Nowadays, the veil of ignorance is challenged by a powerful but ancient contender: the veil of opulence. While no serious political philosopher actually defends such a device — the term is my own — the veil of opulence runs thick in our political discourse. Where the veil of ignorance offers a test for fairness from an impersonal, universal point of view — “What system would I want if I had no idea who I was going to be, or what talents and resources I was going to have?” — the veil of opulence offers a test for fairness from the first-person, partial point of view: “What system would I want if I were so-and-so?”
  • Those who don the veil of opulence may imagine themselves to be fantastically wealthy movie stars or extremely successful business entrepreneurs. They vote and set policies according to this fantasy. “If I were such and such a wealthy person,” they ask, “how would I feel about giving X percentage of my income, or Y real dollars per year, to pay for services that I will never see nor use?
  • the veil of opulence operates only under the guise of fairness. It is rather a distortion of fairness, by virtue of the partiality that it smuggles in. It asks not whether a policy is fair given the huge range of advantages or hardships the universe might throw at a person but rather whether it is fair that a very fortunate person should shoulder the burdens of others. That is, the veil of opulence insists that people imagine that resources and opportunities and talents are freely available to all, that such goods are widely abundant, that there is no element of randomness or chance that may negatively impact those who struggle to succeed but sadly fail through no fault of their own. It blankets off the obstacles that impede the road to success. It turns a blind eye to the adversity that some people, let’s face it, are born into. By insisting that we consider public policy from the perspective of the most-advantaged, the veil of opulence obscures the vagaries of brute luck.
  • ...5 more annotations...
  • If there’s one thing about fairness, it is fundamentally an impartial notion, an idea that restricts us from privileging one group over another. When asking about fairness, we cannot ask whether X policy is fair for me, or whether Y policy is fair for someone with a yacht and two vacation homes. We must ask whether Z policy is fair, full stop. What we must ask here is whether the policy could be applied to all; whether it is the sort of system with which we could live, if we were to end up in one of the many socioeconomic groupings that make up our diverse community, whether most-advantaged or least-advantaged, fortunate or unfortunate
  • This is why the veil of ignorance is a superior test for fairness over the veil of opulence. It tackles the universality of fairness without getting wrapped up in the particularities of personal interest. If you were to start this world anew, unaware of who you would turn out to be, what sort of die would you be willing to cast?
  • In the interest of firming up the game, in the interest of being fair, the N.F.L. decided long ago to give the worst teams in football the best shot at improving their game.
  • The question of fairness has widespread application throughout our political discourse. It affects taxation, health care, education, social safety nets and so on. The veil of opulence would have us screen for fairness by asking what the most fortunate among us are willing to bear. The veil of ignorance would have us screen for fairness by asking what any of us would be willing to bear, if it were the case that we, or the ones we love, might be born into difficult circumstances or, despite our hard work, blindsided by misfortune.
  • Society is in place to correct for the injustices of the universe, to ensure that our lives can run smoothly despite the stuff that is far out of our control: not to hand us what we need, but to give us the opportunity to pursue life, liberty and happiness.

On Political Disagreement - NYTimes.com - 0 views

  • On most political matters, then, we have what philosophers call “epistemic peers” — people at least our equals in the intellectual qualities needed to made good judgments about a given matter — who disagree with us. What should we make of this fact?
  • freedom of thought does not imply correctness of thought: my political right to assert my views does not mean that I have good reasons for holding them.
  • when epistemic peers disagree with me, I have a good reason to question my views. Shouldn’t I see their disagreeing as another piece of evidence in the political debate, one that may tip the balance against the case I have for my position.
  • ...1 more annotation...
  • the restaurant disagreement is highly localized.  Our different results do not mean we disagree on other topics.  Political disagreements, however, go wide and deep.  If we disagree about health care, we likely also disagree on welfare, budget deficits and regulating business.  And this range of disagreements may well be because of differences in fundamental values.  Such thoroughgoing differences suggest that I should not see those on the other side as epistemic peers.

Memory and the Cybermind - NYTimes.com - 0 views

  • When we’re faced with hard questions, we don’t search our minds — we first think of the Web.
  • Has this computer dependency made people stupid? In a further study, our group looked into the effect of computer availability on memory. We asked people to type into a computer 40 factoids they had each just been given. (For example, French fries are originally from Belgium, not France.) Those who were told the computer would not record these facts tended often to remember the facts themselves. But those told that the computer would record everything were inclined promptly to forget them. Knowing we can fall back on our computers makes us fail to store information in our own memories.
  • Each time we learn who knows something or where we can find information — without learning what the information itself might be — we are expanding our mental reach. This is the basic idea behind so-called transactive memory. In 1985, with my collaborators Toni Giuliano (who is also my wife) and Paula Hertel, I wrote a paper introducing the idea of transactive memory as a way to understand the group mind. We observed that nobody remembers everything. Instead, each of us in a couple or group remembers some things personally — and then can remember much more by knowing who else might know what we don’t. In this way, we become part of a transactive memory system.

  • Groups of people commonly depend on one another for memory in this way — not by all knowing the same thing, but by specializing. And now we’ve added our computing devices to the network, depending for memory not just on people but also on a cloud of linked people and specialized information-filled devices.
  • We have all become a great cybermind. As long as we are connected to our machines through talk and keystrokes, we can all be part of the biggest, smartest mind ever.

  • visualizing a successful outcome, under certain conditions, can make people less likely to achieve it. She rendered her experimental participants dehydrated, then asked some of them to picture a refreshing glass of water. The water-visualizers experienced a marked decline in energy levels, compared with those participants who engaged in negative or neutral fantasies. Imagining their goal seemed to deprive the water-visualizers of their get-up-and-go, as if they’d already achieved their objective.

  • the relentless cheer of positive thinking begins to seem less like an expression of joy and more like a stressful effort to stamp out any trace of negativity.

North Carolina passes law banning new science from guiding coastal policies - 0 views

  • North Carolina has banned using recent science to guide policy making. House Bill 819, which passed today after the governor let the deadline to stop it slip, restricts all sea-level predictions used for policy-making to be based on "historical data," effectively sending science back to 1900. The law will prevent policy-makers from using a recent study by the state's Coastal Resources Commission (CRC) which predicted the sea level will rise by 39 inches in the next century.

  • There are philosophers and scientists who say we will never understand the universe, we can't fathom the endless details or make good sense of the whole. We can try, but the universe is too big. The writer John Updike once explained the argument this way to reporter Jim Holt: "It's beyond our intellectual limits as a species. Put yourself into the position of a dog. A dog is responsive, shows intuition, looks at us with eyes behind which there is intelligence of a sort, and yet a dog must not understand most of the things it sees people doing. It must have no idea how they invented, say, the internal combustion engine. So maybe what we need to do is imagine that we're dogs and that there are realms that go beyond our understanding."
  • So does the universe get the crown?

  • et the brain has its champions. "Consider the human brain," says physicist Sir Roger Penrose. "If you look at the entire physical cosmos, our brains are a tiny, tiny part of it. But they're the most perfectly organized part. Compared to the complexity of a brain, a galaxy is just an inert lump
  • my hunch is the universe will still outwit us, will still be "too wonderful" to be decoded, because we are, in the end, so much smaller than it is. And that's not a bad thing. To my mind, it's the search that matters, that sharpens us, gives us something noble to do.
  • Steven Weinberg famously said, "The effort to understand the universe is one of the very few things that lifts human life a little above the level of farce, and gives it some of the grace of tragedy."

Adam Kirsch: Art Over Biology | The New Republic - 1 views

  • Nietzsche, who wrote in Human, All Too Human, under the rubric “Art dangerous for the artist,” about the particular ill-suitedness of the artist to flourishing in a modern scientific age: When art seizes an individual powerfully, it draws him back to the views of those times when art flowered most vigorously.... The artist comes more and more to revere sudden excitements, believes in gods and demons, imbues nature with a soul, hates science, becomes unchangeable in his moods like the men of antiquity, and desires the overthrow of all conditions that are not favorable to art.... Thus between him and the other men of his period who are the same age a vehement antagonism is finally generated, and a sad end
  • What is modern is the sense of the superiority of the artist’s inferiority, which is only possible when the artist and the intellectual come to see the values of ordinary life—prosperity, family, worldly success, and happiness—as inherently contemptible.
  • Art, according to a modern understanding that has not wholly vanished today, is meant to be a criticism of life, especially of life in a materialist, positivist civilization such as our own. If this means the artist does not share in civilization’s boons, then his suffering will be a badge of honor.

  • The iron law of Darwinian evolution is that everything that exists strives with all its power to reproduce, to extend life into the future, and that every feature of every creature can be explained as an adaptation toward this end. For the artist to deny any connection with the enterprise of life, then, is to assert his freedom from this universal imperative; to reclaim negatively the autonomy that evolution seems to deny to human beings. It is only because we can freely choose our own ends that we can decide not to live for life, but for some other value that we posit. The artist’s decision to produce spiritual offspring rather than physical ones is thus allied to the monk’s celibacy and the warrior’s death for his country, as gestures that deny the empire of mere life.
  • Animals produce beauty on their bodies; humans can also produce it in their artifacts. The natural inference, then, would be that art is a human form of sexual display, a way for males to impress females with spectacularly redundant creations.
  • For Darwin, the human sense of beauty was not different in kind from the bird’s.
  • Still, Darwin recognized that the human sense of beauty was mediated by “complex ideas and trains of thought,” which make it impossible to explain in terms as straightforward as a bird’s:
  • with the rise of evolutionary psychology, it was only a matter of time before the attempt was made to explain art in Darwinian terms. After all, if ethics and politics can be explained by game theory and reciprocal altruism, there is no reason why aesthetics should be different: in each case, what appears to be a realm of human autonomy can be reduced to the covert expression of biological imperatives
  • Put more positively, one might say that any given work of art can be discussed critically and historically, but not deduced from the laws of evolution.
  • Still, there is an unmistakable sense in discussions of Darwinian aesthetics that by linking art to fitness, we can secure it against charges of irrelevance or frivolousness—that mattering to reproduction is what makes art, or anything, really matter.
  • In particular, Darwin suggests that it is impossible to explain the history or the conventions of any art by the general imperatives of evolution
  • Dutton’s Darwinism was aesthetically conservative: “Darwinian aesthetics,” he wrote, “can restore the vital place of beauty, skill, and pleasure as high artistic values.” Dutton’s argument has recently been reiterated and refined by a number of new books,
  • “The universality of art and artistic behaviors, their spontaneous appearance everywhere across the globe ... and the fact that in most cases they can be easily recognized as artistic across cultures suggest that they derive from a natural, innate source: a universal human psychology.”
  • Again like language, art is universal in the sense that any local expression of it can be “learned” by anyone.
  • Yet earlier theorists of evolution were reluctant to say that art was an evolutionary adaptation like language, for the simple reason that it does not appear to be evolutionarily adaptive.
  • Stephen Jay Gould suggested that art was not an evolutionary adaptation but what he called a “spandrel”—that is, a showy but accidental by-product of other adaptations that were truly functiona
  • the very words “success” and “failure,” despite themselves, bring an emotive and ethical dimension into the discussion, so impossible is it for human beings to inhabit a valueless world. In the nineteenth century, the idea that fitness for survival was a positive good motivated social Darwinism and eugenics. Proponents of these ideas thought that in some way they were serving progress by promoting the flourishing of the human race, when the basic premise of Darwinism is that there is no such thing as progress or regress, only differential rates of reproduction
  • The first popular effort in this direction was the late Denis Dutton’s much-discussed book The Art Instinct, which appeared in 2009.
  • Boyd begins with the premise that human beings are pattern-seeking animals: both our physical perceptions and our social interactions are determined by our brain’s innate need to find and to
  • Art, then, can be defined as the calisthenics of pattern-finding. “Just as animal physical play refines performance, flexibility, and efficiency in key behaviors,” Boyd writes, “so human art refines our performance in our key perceptual and cognitive modes, in sight (the visual arts), sound (music), and social cognition (story). These three modes of art, I propose, are adaptations ... they show evidence of special design in humans, design that offers survival and especially reproductive advantages.”

Chick-fil-A is Bad For Your Political Health | Patrol - A review of religion and the mo... - 0 views

  • The premise is that politics and economics are separate realms, and we are “creating a culture” of division by dragging politics into such things as economic transactions. One could hardly better encapsulate the reality we live under, where economics have completely replaced politics. That’s pretty much the definition of classical liberalism: true politics, where human values are disputed, are expected to be sublimated by economic transactions.
  • The winner is the corporation, which can now reap the profits of a society where no human value is allowed to be more important than a business deal. (If you question that orthodoxy, you’re likely to be labeled a “radical” or a “partisan,” or better yet, just “too political.”) This ideology owes its entire existence to the need for capitalists to keep human values out of the way of the market. Above all, it must keep politics a dirty word, because people who know what politics are and how to use them can cause trouble for capitalists very quickly.
  • our commercial and our political lives are already completely intermeshed, because under the current regime we basically only have commercial lives. The only political power to be had in the United States is money, and even if you don’t have enough to make a corporation hurt, how you consume is one of the few expressions of political will open to the average citizen. They may not have enough money to shake the economy, and may not even when pooled with a large group of like-minded people. But a visceral awareness that money is politics is an excellent first step toward the average person realizing his or her political agency and taking responsibility for it.

  • Even if the corporatization of our society is so complete that it is objectively impossible to avoid giving money to entities that are at that very moment working to undermine our political freedoms, every religious and ethically-minded institution should be urging those under its influence to be aware and resist wherever possible.
  • In sum, you should absolutely be supporting corporations that put human values ahead of profit, and doing your best to keep your dollars away from ones that exploit workers and try to obstruct democracy, whether directly by stripping workers of their rights or indirectly by supporting the exclusionary social fantasies of religious reactionaries.

Christine Rosen: The Machine And The Ghost | The New Republic - 0 views

  • Ultimately, the goal of creators of Ambient Intelligence and persuasive technologies and the Internet of Things is not merely to offer context-aware, adaptive, personalized responses in real time, but to divine future needs. As one contributor to The New Everyday noted, eventually these technologies will “anticipate your desires without conscious mediation.” 
  • The challenge for ethicists such as Verbeek is whether a society composed of “smart” cities like Songdo might also bring an increase in moral laziness and a decline in individual freedom. Freedom is a hollow promise in the absence of agency and choice. 
  • these technologies also undermine a crucial (albeit often maligned) human quality: self-deception. Self-deception is inefficient. It causes problems. It makes things messy—which is why our technologists would like us to replace it with the seemingly greater honesty of data that, once processed, promise to know us better than we know ourselves. But being human is a messy business; and exercising judgment and self-control, and learning the complicated social norms that signal acceptable behavior, are the very things that make us human.

  • in a broader sense, as the case of genetic testing has shown, the right not to know some things (like the right to forget foolish, youthful behavior that is now permanently archived on the Internet) is as crucially important (if not more so) in our age as the voracious pursuit of information and transparency. 
  • Merely because something is possible, is it also desirable? And if it is possible, must we immediately accommodate ourselves to it? In The Forlorn Demon, Allen Tate noted, “We no longer ask, ‘Is it right?’ We ask: ‘Does it work?’” In our contemporary engagement with technology, we would do well to spend more time with the first question, even as we live ever more mediated lives relentlessly pursuing an answer to the second.

  • The depressing conclusion of a faculty report: “failing math at all levels affects retention more than any other academic factor.” A national sample of transcripts found mathematics had twice as many F’s and D’s compared as other subjects.
  • Of all who embark on higher education, only 58 percent end up with bachelor’s degrees. The main impediment to graduation: freshman math.
  • California’s two university systems, for instance, consider applications only from students who have taken three years of mathematics and in that way exclude many applicants who might excel in fields like art or history. Community college students face an equally prohibitive mathematics wall. A study of two-year schools found that fewer than a quarter of their entrants passed the algebra classes they were required to take.
  • Nor will just passing grades suffice. Many colleges seek to raise their status by setting a high mathematics bar. Hence, they look for 700 on the math section of the SAT, a height attained in 2009 by only 9 percent of men and 4 percent of women. And it’s not just Ivy League colleges that do this: at schools like Vanderbilt, Rice and Washington University in St. Louis, applicants had best be legacies or athletes if they have scored less than 700 on their math SATs.
  • “mathematical reasoning in workplaces differs markedly from the algorithms taught in school.” Even in jobs that rely on so-called STEM credentials — science, technology, engineering, math — considerable training occurs after hiring, including the kinds of computations that will be required.
  • I fully concur that high-tech knowledge is needed to sustain an advanced industrial economy. But we’re deluding ourselves if we believe the solution is largely academic.
  • a definitive analysis by the Georgetown Center on Education and the Workforce forecasts that in the decade ahead a mere 5 percent of entry-level workers will need to be proficient in algebra or above.

  • “Our civilization would collapse without mathematics.” He’s absolutely right.
  • Quantitative literacy clearly is useful in weighing all manner of public policies
  • Mathematics is used as a hoop, a badge, a totem to impress outsiders and elevate a profession’s status.
  • Instead of investing so much of our academic energy in a subject that blocks further attainment for much of our population, I propose that we start thinking about alternatives. Thus mathematics teachers at every level could create exciting courses in what I call “citizen statistics.” This would not be a backdoor version of algebra, as in the Advanced Placement syllabus. Nor would it focus on equations used by scholars when they write for one another. Instead, it would familiarize students with the kinds of numbers that describe and delineate our personal and public lives.
  • This need not involve dumbing down. Researching the reliability of numbers can be as demanding as geometry.
  • I hope that mathematics departments can also create courses in the history and philosophy of their discipline, as well as its applications in early cultures. Why not mathematics in art and music — even poetry — along with its role in assorted sciences? The aim would be to treat mathematics as a liberal art, making it as accessible and welcoming as sculpture or ballet
  • Yes, young people should learn to read and write and do long division, whether they want to or not. But there is no reason to force them to grasp vectorial angles and discontinuous functions. Think of math as a huge boulder we make everyone pull, without assessing what all this pain achieves. So why require it, without alternatives or exceptions? Thus far I haven’t found a compelling answer.

What Have We Learned, If Anything? by Tony Judt | The New York Review of Books - 0 views

  • During the Nineties, and again in the wake of September 11, 2001, I was struck more than once by a perverse contemporary insistence on not understanding the context of our present dilemmas, at home and abroad; on not listening with greater care to some of the wiser heads of earlier decades; on seeking actively to forget rather than remember, to deny continuity and proclaim novelty on every possible occasion. We have become stridently insistent that the past has little of interest to teach us. Ours, we assert, is a new world; its risks and opportunities are without precedent.
  • the twentieth century that we have chosen to commemorate is curiously out of focus. The overwhelming majority of places of official twentieth-century memory are either avowedly nostalgo-triumphalist—praising famous men and celebrating famous victories—or else, and increasingly, they are opportunities for the recollection of selective suffering.
  • The problem with this lapidary representation of the last century as a uniquely horrible time from which we have now, thankfully, emerged is not the description—it was in many ways a truly awful era, an age of brutality and mass suffering perhaps unequaled in the historical record. The problem is the message: that all of that is now behind us, that its meaning is clear, and that we may now advance—unencumbered by past errors—into a different and better era.

  • Today, the “common” interpretation of the recent past is thus composed of the manifold fragments of separate pasts, each of them (Jewish, Polish, Serb, Armenian, German, Asian-American, Palestinian, Irish, homosexual…) marked by its own distinctive and assertive victimhood.
  • The resulting mosaic does not bind us to a shared past, it separates us from it. Whatever the shortcomings of the national narratives once taught in school, however selective their focus and instrumental their message, they had at least the advantage of providing a nation with past references for present experience. Traditional history, as taught to generations of schoolchildren and college students, gave the present a meaning by reference to the past: today’s names, places, inscriptions, ideas, and allusions could be slotted into a memorized narrative of yesterday. In our time, however, this process has gone into reverse. The past now acquires meaning only by reference to our many and often contrasting present concerns.
  • the United States thus has no modern memory of combat or loss remotely comparable to that of the armed forces of other countries. But it is civilian casualties that leave the most enduring mark on national memory and here the contrast is piquant indeed
  • Today, the opposite applies. Most people in the world outside of sub-Saharan Africa have access to a near infinity of data. But in the absence of any common culture beyond a small elite, and not always even there, the fragmented information and ideas that people select or encounter are determined by a multiplicity of tastes, affinities, and interests. As the years pass, each one of us has less in common with the fast-multiplying worlds of our contemporaries, not to speak of the world of our forebears.
  • What is significant about the present age of transformations is the unique insouciance with which we have abandoned not merely the practices of the past but their very memory. A world just recently lost is already half forgotten.
  • In the US, at least, we have forgotten the meaning of war. There is a reason for this. I
  • Until the last decades of the twentieth century most people in the world had limited access to information; but—thanks to national education, state-controlled radio and television, and a common print culture—within any one state or nation or community people were all likely to know many of the same things.
  • it was precisely that claim, that “it’s torture, and therefore it’s no good,” which until very recently distinguished democracies from dictatorships. We pride ourselves on having defeated the “evil empire” of the Soviets. Indeed so. But perhaps we should read again the memoirs of those who suffered at the hands of that empire—the memoirs of Eugen Loebl, Artur London, Jo Langer, Lena Constante, and countless others—and then compare the degrading abuses they suffered with the treatments approved and authorized by President Bush and the US Congress. Are they so very different?
  • As a consequence, the United States today is the only advanced democracy where public figures glorify and exalt the military, a sentiment familiar in Europe before 1945 but quite unknown today
  • the complacent neoconservative claim that war and conflict are things Americans understand—in contrast to naive Europeans with their pacifistic fantasies—seems to me exactly wrong: it is Europeans (along with Asians and Africans) who understand war all too well. Most Americans have been fortunate enough to live in blissful ignorance of its true significance.
  • That same contrast may account for the distinctive quality of much American writing on the cold war and its outcome. In European accounts of the fall of communism, from both sides of the former Iron Curtain, the dominant sentiment is one of relief at the closing of a long, unhappy chapter. Here in the US, however, the story is typically recorded in a triumphalist key.5
  • For many American commentators and policymakers the message of the twentieth century is that war works. Hence the widespread enthusiasm for our war on Iraq in 2003 (despite strong opposition to it in most other countries). For Washington, war remains an option—on that occasion the first option. For the rest of the developed world it has become a last resort.6
  • Ignorance of twentieth-century history does not just contribute to a regrettable enthusiasm for armed conflict. It also leads to a misidentification of the enemy.
  • This abstracting of foes and threats from their context—this ease with which we have talked ourselves into believing that we are at war with “Islamofascists,” “extremists” from a strange culture, who dwell in some distant “Islamistan,” who hate us for who we are and seek to destroy “our way of life”—is a sure sign that we have forgotten the lesson of the twentieth century: the ease with which war and fear and dogma can bring us to demonize others, deny them a common humanity or the protection of our laws, and do unspeakable things to them.
  • How else are we to explain our present indulgence for the practice of torture? For indulge it we assuredly do.
  • “But what would I have achieved by proclaiming my opposition to torture?” he replied. “I have never met anyone who is in favor of torture.”8 Well, times have changed. In the US today there are many respectable, thinking people who favor torture—under the appropriate circumstances and when applied to those who merit it.
  • American civilian losses (excluding the merchant navy) in both world wars amounted to less than 2,000 dead.
  • We are slipping down a slope. The sophistic distinctions we draw today in our war on terror—between the rule of law and “exceptional” circumstances, between citizens (who have rights and legal protections) and noncitizens to whom anything can be done, between normal people and “terrorists,” between “us” and “them”—are not new. The twentieth century saw them all invoked. They are the selfsame distinctions that licensed the worst horrors of the recent past: internment camps, deportation, torture, and murder—those very crimes that prompt us to murmur “never again.” So what exactly is it that we think we have learned from the past? Of what possible use is our self-righteous cult of memory and memorials if the United States can build its very own internment camp and torture people there?
  • We need to learn again—or perhaps for the first time—how war brutalizes and degrades winners and losers alike and what happens to us when, having heedlessly waged war for no good reason, we are encouraged to inflate and demonize our enemies in order to justify that war’s indefinite continuance.

Does Thinking Really Hard Burn More Calories?: Scientific American - 0 views

  • Just as vigorous exercise tires our bodies, intellectual exertion should drain the brain. What the latest science reveals, however, is that the popular notion of mental exhaustion is too simplistic. The brain continuously slurps up huge amounts of energy for an organ of its size, regardless of whether we are tackling integral calculus or clicking through the week's top 10 LOLcats. Although firing neurons summon extra blood, oxygen and glucose, any local increases in energy consumption are tiny compared with the brain's gluttonous baseline intake. So, in most cases, short periods of additional mental effort require a little more brainpower than usual, but not much more.
  • something must explain the feeling of mental exhaustion, even if its physiology differs from physical fatigue. Simply believing that our brains have expended a lot of effort might be enough to make us lethargic.
  • a typical adult human brain runs on around 12 watts—a fifth of the power required by a standard 60 watt lightbulb. Compared with most other organs, the brain is greedy; pitted against man-made electronics, it is astoundingly efficient. IBM's Watson, the supercomputer that defeated Jeopardy! champions, depends on ninety IBM Power 750 servers, each of which requires around one thousand watts.

  • Such fatigue seems much more likely to follow sustained mental effort that we do not seek for pleasure—such as the obligatory SAT—especially when we expect that the ordeal will drain our brains. If we think an exam or puzzle will be difficult, it often will be.
  • people routinely enjoy intellectually invigorating activities without suffering mental exhaustion.
  • Studies have shown that something similar happens when people exercise and play sports: a large component of physical exhaustion is in our heads. In related research, volunteers that cycled on an exercise bike following a 90-minute computerized test of sustained attention quit pedaling from exhaustion sooner than participants that watched emotionally neutral documentaries before exercising
  • In the specific case of the SAT, something beyond pure mental effort likely contributes to post-exam stupor: stress. After all, the brain does not function in a vacuum. Other organs burn up energy, too. Taking an exam that partially determines where one will spend the next four years is nerve-racking enough to send stress hormones swimming through the blood stream, induce sweating, quicken heart rates and encourage fidgeting and contorted body postures. The SAT and similar trials are not just mentally taxing—they are physically exhausting, too.

Silicon Valley Worries About Addiction to Devices - NYTimes.com - 0 views

  • founders from Facebook, Twitter, eBay, Zynga and PayPal, and executives and managers from companies like Google, Microsoft, Cisco and others listened to or participated
  • they debated whether technology firms had a responsibility to consider their collective power to lure consumers to games or activities that waste time or distract them.
  • Eric Schiermeyer, a co-founder of Zynga, an online game company and maker of huge hits like FarmVille, has said he has helped addict millions of people to dopamine, a neurochemical that has been shown to be released by pleasurable activities, including video game playing, but also is understood to play a major role in the cycle of addiction. But what he said he believed was that people already craved dopamine and that Silicon Valley was no more responsible for creating irresistible technologies than, say, fast-food restaurants were responsible for making food with such wide appeal. “They’d say: ‘Do we have any responsibility for the fact people are getting fat?’ Most people would say ‘no,’ ” said Mr. Schiermeyer. He added: “Given that we’re human, we already want dopamine.”

  • This kind of modeling is already in use to study individual cellular processes like metabolism. But Dr. Covert said: “Where I think our work is different is that we explicitly include all of the genes and every known gene function. There’s no one else out there who has been able to include more than a handful of functions or more than, say, one-third of the genes.”
  • The simulation, which runs on a cluster of 128 computers, models the complete life span of the cell at the molecular level, charting the interactions of 28 categories of molecules — including DNA, RNA, proteins and small molecules known as metabolites, which are generated by cell processes.
  • They called the simulation an important advance in the new field of computational biology, which has recently yielded such achievements as the creation of a synthetic life form — an entire bacterial genome created by a team led by the genome pioneer J. Craig Venter. The scientists used it to take over an existing cell.
  • A decade ago, scientists developed simulations of metabolism that are now being used to study a wide array of cells, including bacteria, yeast and photosynthetic organisms. Other models exist for processes like protein synthesis.
  • “Right now, running a simulation for a single cell to divide only one time takes around 10 hours and generates half a gigabyte of data,” Dr. Covert wrote. “I find this fact completely fascinating, because I don’t know that anyone has ever asked how much data a living thing truly holds. We often think of the DNA as the storage medium, but clearly there is more to it than that.”
  • scientists chose an approach called object-oriented programming, which parallels the design of modern software systems. Software designers organize their programs in modules, which communicate with one another by passing data and instructions back and forth.
  • “The major modeling insight we had a few years ago was to break up the functionality of the cell into subgroups, which we could model individually, each with its own mathematics, and then to integrate these submodels together into a whole,”

Martha C. Nussbaum and David V. Johnson: The New Religious Intolerance - 2 views

  • you analyze fear as the emotion principally responsible for religious intolerance. You label fear the “narcissistic emotion.” But why think that the logic of fear—erring on the side of caution (“better to be safe than sorry”)—is narcissism rather than just good common sense, especially in an era of global terrorism and instability? MN: Biological and psychological research on fear shows that it is in some respects more primitive than other emotions, involving parts of the brain that do not deal in reflection and balancing. It also focuses narrowly on the person’s own survival, which is useful in evolutionary terms, but not so useful if one wants a good society. These tendencies to narrowness can be augmented, as I show in my book, through rhetorical manipulation. Fear is a major source of the denial of equal respect to others. Fear is sometimes appropriate, of course, and I give numerous examples of this. But its tendencies toward narrowness make it easily manipulable by false information and rhetorical hype.
  • DJ: In comparing fear and empathy, you say that empathy “has its own narcissism.” Do all emotions have their own forms of narcissism, and if so, why call fear "a narcissistic emotion"? MN: What I meant by my remarks about empathy is that empathy typically functions within a small circle, and is activated by vivid narratives, as Daniel Batson’s wonderful research has shown. So it is uneven and partial. But it is not primarily self-focused, as fear is. As John Stuart Mill said, fear tells us what we need to protect against for ourselves, and empathy helps us extend that protection to others.
  • MN: I think it’s OK to teach religious texts as literature, but better to teach them as history and social reality as part of learning what other people in one’s society believe and take seriously. I urge that all young people should get a rich and non-stereotypical understanding of all the major world religions. In the process, of course, the teacher must be aware of the multiplicity of interpretations and sects within each religion

  • DJ: Of the basic values of French liberalism—liberty, equality, and fraternity—the last, fraternity, always seems to get short shrift. Your book, by contrast, argues that religious tolerance and liberalism in general can only flourish if people cultivate active respect, civility, and civic friendship with their fellow citizens. If this is so crucial, why do traditional liberals fail to make it more central to their program?
  • MN: I think liberals associate the cultivation of public emotion with fascism and other illiberal ideologies. But if they study history more closely they will find many instances in which emotions are deliberately cultivated in the service of liberal ideals. My next book, Political Emotions, will study all of this in great detail. Any political principles that ask people to go beyond their own self-interest for the sake of justice requires the cultivation of emotion.
  • In the history of philosophy this was well understood, and figures as diverse as [Jean-Jacques] Rousseau, [Johann Gottfried von] Herder, [Giuseppe] Mazzini, Auguste Comte, John Stuart Mill, and John Rawls had a lot to say about the issue. In Mill’s case, he set about solving the problem posed by the confluence of liberalism and emotion: how can a society that cultivates emotion to support its political principles also preserve enough space for dissent, critique, and experimentation? My own proposal in the forthcoming book follows the lead of Mill—and, in India, of Rabindranath Tagore—and tries to show how a public culture of emotions, supporting the stability of good political principles, can also be liberal and protective of dissent. Some of the historical figures I study in this regard are Franklin Delano Roosevelt, Martin Luther King, Jr., Gandhi, and Nehru.
  • critics of the burqa typically look at the practices of others and find sexism and “objectification” of women there, while failing to look at the practices of the dominant culture, which are certainly suffused with sexism and objectification. I was one of the feminist philosophers who wrote about objectification as a fundamental problem, and what we were talking about was the portrayal of women as commodities for male use and control in violent pornography, in a great deal of our media culture, and in other cultural practices, such as plastic surgery. I would say that this type of objectification is not on the retreat but may even be growing. Go to a high school dance—even at a high-brow school such as the John Dewey Laboratory School on our campus [at the University of Chicago]—and you will see highly individual and intelligent teenage girls marketing themselves for male consumption in indistinguishable microskirts, prior to engaging in a form of group dancing that mimes sex, and effaces their individuality. (Boys wear regular and not particularly sexy clothing.)
  • Lots of bad things are and will remain legal: unkindness, emotional blackmail, selfishness. And though I think the culture of pornographic objectification does great damage to personal relations, I don’t think that legal bans are the answer.
  • we should confront sexism by argument and persuasion, and that to render all practices that objectify women illegal would be both too difficult (who would judge?) and too tyrannical.
  • the Palin reaction was a whole lot better than the standard reaction in Europe, which is that we should just ban things that we fear. It is really unbelievable, having just lectured on this topic here in Germany: my views, which are pretty mainstream in America, are found “extreme” and even “offensive” in Germany, and all sorts of quite refined people think that Islam poses a unique problem and that the law should be dragged in to protect the culture.
  • The problem with these Europeans is that they don’t want to ban platform shoes or spike heels either; they just want to ban practices of others which they have never tried to understand.

Atul Gawande: Failure and Rescue : The New Yorker - 0 views

  • the critical skills of the best surgeons I saw involved the ability to handle complexity and uncertainty. They had developed judgment, mastery of teamwork, and willingness to accept responsibility for the consequences of their choices. In this respect, I realized, surgery turns out to be no different than a life in teaching, public service, business, or almost anything you may decide to pursue. We all face complexity and uncertainty no matter where our path takes us. That means we all face the risk of failure. So along the way, we all are forced to develop these critical capacities—of judgment, teamwork, and acceptance of responsibility.
  • people admonish us: take risks; be willing to fail. But this has always puzzled me. Do you want a surgeon whose motto is “I like taking risks”? We do in fact want people to take risks, to strive for difficult goals even when the possibility of failure looms. Progress cannot happen otherwise. But how they do it is what seems to matter. The key to reducing death after surgery was the introduction of ways to reduce the risk of things going wrong—through specialization, better planning, and technology.
  • there continue to be huge differences between hospitals in the outcomes of their care. Some places still have far higher death rates than others. And an interesting line of research has opened up asking why.
  • ...8 more annotations...
  • I thought that the best places simply did a better job at controlling and minimizing risks—that they did a better job of preventing things from going wrong. But, to my surprise, they didn’t. Their complication rates after surgery were almost the same as others. Instead, what they proved to be really great at was rescuing people when they had a complication, preventing failures from becoming a catastrophe.
  • this is what distinguished the great from the mediocre. They didn’t fail less. They rescued more.
  • This may in fact be the real story of human and societal improvement. We talk a lot about “risk management”—a nice hygienic phrase. But in the end, risk is necessary. Things can and will go wrong. Yet some have a better capacity to prepare for the possibility, to limit the damage, and to sometimes even retrieve success from failure.
  • When things go wrong, there seem to be three main pitfalls to avoid, three ways to fail to rescue. You could choose a wrong plan, an inadequate plan, or no plan at all. Say you’re cooking and you inadvertently set a grease pan on fire. Throwing gasoline on the fire would be a completely wrong plan. Trying to blow the fire out would be inadequate. And ignoring it—“Fire? What fire?”—would be no plan at all.
  • All policies court failure—our war in Iraq, for instance, or the effort to stimulate our struggling economy. But when you refuse to even acknowledge that things aren’t going as expected, failure can become a humanitarian disaster. The sooner you’re able to see clearly that your best hopes and intentions have gone awry, the better. You have more room to pivot and adjust. You have more of a chance to rescue.
  • But recognizing that your expectations are proving wrong—accepting that you need a new plan—is commonly the hardest thing to do. We have this problem called confidence. To take a risk, you must have confidence in yourself
  • Yet you cannot blind yourself to failure, either. Indeed, you must prepare for it. For, strangely enough, only then is success possible.
  • So you will take risks, and you will have failures. But it’s what happens afterward that is defining. A failure often does not have to be a failure at all. However, you have to be ready for it—will you admit when things go wrong? Will you take steps to set them right?—because the difference between triumph and defeat, you’ll find, isn’t about willingness to take risks. It’s about mastery of rescue.
