Raymond Tallis Takes Out the 'Neurotrash' - The Chronicle Review - The Chronicle of Higher Education - 0 views

  • Tallis informs 60 people gathered in a Kent lecture hall that his talk will demolish two "pillars of unwisdom." The first, "neuromania," is the notion that to understand people you must peer into the "intracranial darkness" of their skulls with brain-scanning technology. The second, "Darwinitis," is the idea that Charles Darwin's evolutionary theory can explain not just the origin of the human species—a claim Tallis enthusiastically accepts—but also the nature of human behavior and institutions.
  • Aping Mankind argues that neuroscientific approaches to things like love, wisdom, and beauty are flawed because you can't reduce the mind to brain activity alone.
  • Stephen Cave, a Berlin-based philosopher and writer who has called Aping Mankind "an important work," points out that most philosophers and scientists do in fact believe "that mind is just the product of certain brain activity, even if we do not currently know quite how." Tallis "does both the reader and these thinkers an injustice" by declaring that view "obviously" wrong,

  • Geraint Rees, director of University College London's Institute of Cognitive Neuroscience, complains that reading Tallis is "a bit like trying to nail jelly to the wall." He "rubbishes every current theory of the relationship between mind and brain, whether philosophical or neuroscientific," while offering "little or no alternative,"
  • cultural memes. The Darwinesque concept originates in Dawkins's 1976 book, The Selfish Gene. Memes are analogous to genes, Dennett has said, "replicating units of culture" that spread from mind to mind like a virus. Religion, chess, songs, clothing, tolerance for free speech—all have been described as memes. Tallis considers it absurd to talk of a noun-phrase like "tolerance for free speech" as a discrete entity. But Dennett argues that Tallis's objections are based on "a simplistic idea of what one might mean by a unit." Memes aren't units? Well, in that spirit, says Dennett, organisms aren't units of biology, nor are species—they're too complex, with too much variation. "He's got to allow theory to talk about entities which are not simple building blocks," Dennett says.
  • How is it that he perceives the glass of water on the table? How is it that he feels a sense of self over time? How is it that he can remember a patient he saw in 1973, and then cast his mind forward to his impending visit to the zoo? There are serious problems with trying to reduce such things to impulses in the brain, he argues. We can explain "how the light gets in," he says, but not "how the gaze looks out." And isn't it astonishing, he adds, that much neural activity seems to have no link to consciousness? Instead, it's associated with things like controlling automatic movements and regulating blood pressure. Sure, we need the brain for consciousness: "Chop my head off, and my IQ descends." But it's not the whole story. There is more to perceptions, memories, and beliefs than neural impulses can explain. The human sphere encompasses a "community of minds," Tallis has written, "woven out of a trillion cognitive handshakes of shared attention, within which our freedom operates and our narrated lives are led." Those views on perception and memory anchor his attack on "neurobollocks." Because if you can't get the basics right, he says, then it's premature to look to neuroscience for clues to complex things like love.
  • Yes, many unanswered questions persist. But these are early days, and neuroscience remains immature, says Churchland, a professor emerita of philosophy at University of California at San Diego and author of the subfield-spawning 1986 book Neurophilosophy. In the 19th century, she points out, people thought we'd never understand light. "Well, by gosh," she says, "by the time the 20th century rolls around, it turns out that light is electromagnetic radiation. ... So the fact that at a certain point in time something seems like a smooth-walled mystery that we can't get a grip on, doesn't tell us anything about whether some real smart graduate student is going to sort it out in the next 10 years or not."
  • Dennett claims he's got much of it sorted out already. He wrote a landmark book on the topic in 1991, Consciousness Explained. (The title "should have landed him in court, charged with breach of the Trade Descriptions Act," writes Tallis.) Dennett uses the vocabulary of computer science to explain how consciousness emerges from the huge volume of things happening in the brain all at once. We're not aware of everything, he tells me, only a "limited window." He describes that stream of consciousness as "the activities of a virtual machine which is running on the parallel hardware of the brain." "You—the fruits of all your experience, not just your genetic background, but everything you've learned and done and all your memories—what ties those all together? What makes a self?" Dennett asks. "The answer is, and has to be, the self is like a software program that organizes the activities of the brain."

'Stranger Danger' Makes People Less Empathetic - 0 views

  • Being around strangers can cause people stress and, in turn, make them less able to feel others' pain, new research suggests.
  • The study suggests that people's default response is to be empathetic toward others but that stress inhibits their ability to feel others' pain. The findings also underscore how deeply hardwired the fear of stranger danger is, in both mice and humans.
  • From an evolutionary standpoint, that makes sense, as every meeting with a stranger has a higher risk of resulting in violence

Book Review: 'A New History of Life' by Peter Ward and Joe Kirschvink - WSJ - 0 views

  • I imagine that physicists are similarly deluged with revelations about how to build a perpetual-motion machine or about the hitherto secret truth behind relativity. And so I didn’t view the arrival of “A New History of Life” with great enthusiasm.
  • subtitle breathlessly promises “radical new discoveries about the origins and evolution of life on earth,” while the jacket copy avers that “our current paradigm for understanding the history of life on Earth dates back to Charles Darwin’s time, yet scientific advances of the last few decades have radically reshaped that aging picture.”
  • authors Peter Ward and Joe Kirschvink are genuine scientists—paleontologists, to be exact. And they can write.
  • ...16 more annotations...
  • even genuine scientists are human and as such susceptible to the allure of offering up new paradigms (as the historian of science Thomas Kuhn put it)
  • paleontologist Stephen Jay Gould insisted that his conception of “punctuated equilibria” (a kind of Marxist biology that blurred the lines between evolution and revolution), which he developed along with fellow paleontologist Niles Eldredge, upended the traditional Darwinian understanding of how natural selection works.
  • This notion doesn’t constitute a fundamental departure from plain old evolution by natural selection; it simply italicizes that sometimes the process is comparatively rapid, other times slower.
  • In addition, they have long had a peculiar perspective on evolution, because of the limitations of the fossil record
  • Darwin was a pioneering geologist as well as the greatest of all biologists, and his insights were backgrounded by the key concept of uniformitarianism, as advocated by Charles Lyell, his friend and mentor
  • previously regnant paradigm among geologists had been “catastrophism
  • fossil record was therefore seen as reflecting the creation and extinction of new species by an array of dramatic and “unnatural” dei ex machina.
  • Of late, however, uniformitarianism has been on a losing streak. Catastrophism is back, with a bang . . . or a flood, or a burst of extraterrestrial radiation, or an onslaught of unpleasant, previously submerged chemicals
  • This emphasis on catastrophes is the first of a triad of novelties on which “A New History of Life” is based. The second involves an enhanced role for some common but insufficiently appreciated inorganic molecules, notably carbon dioxide, oxygen and hydrogen sulfide.
  • Life didn’t so much unfold smoothly over hundreds of millions of years as lurch chaotically in response to diverse crises and opportunities: too much oxygen, too little carbon dioxide, too little oxygen, too much carbon dioxide, too hot, too cold
  • So far, so good, except that in their eagerness to emphasize what is new and different, the authors teeter on the verge of the same trap as Gould: exaggerating the novelty of their own ideas.
  • Things begin to unravel when it comes to the third leg of Messrs. Ward and Kirschvink’s purported paradigmatic novelty: a supposed role for ecosystems—rain forests, deserts, rivers, coral reefs, deep-sea vents—as units of evolutionary change
  • “While the history of life may be populated by species,” they write, “it has been the evolution of ecosystems that has been the most influential factor in arriving at the modern-day assemblage of life. . . . [W]e know that on occasion in the deep past entirely new ecosystems appear, populated by new kinds of life.” True enough, but it is those “new kinds of life,” not whole ecosystems, upon which natural selection acts.
  • One of the most common popular misconceptions about evolution is that it proceeds “for the good of the species.”
  • The problem is that smaller, nimbler units are far more likely to reproduce differentially than are larger, clumsier, more heterogeneous ones. Insofar as ecosystems are consequential for evolution—and doubtless they are—it is because, like occasional catastrophes, they provide the immediate environment within which something not-so-new is acted out.
  • This is natural selection doing its same-old, same-old thing: acting by a statistically potent process of variation combined with selective retention and differential reproduction, a process that necessarily operates within the particular ecosystem that a given lineage occupies.

Why Teenagers Act Crazy - NYTimes.com - 1 views

  • there is a darker side to adolescence that, until now, was poorly understood: a surge during teenage years in anxiety and fearfulness. Largely because of a quirk of brain development, adolescents, on average, experience more anxiety and fear and have a harder time learning how not to be afraid than either children or adults.
  • the brain circuit for processing fear — the amygdala — is precocious and develops way ahead of the prefrontal cortex, the seat of reasoning and executive control. This means that adolescents have a brain that is wired with an enhanced capacity for fear and anxiety, but is relatively underdeveloped when it comes to calm reasoning.
  • the brain’s reward center, just like its fear circuit, matures earlier than the prefrontal cortex. That reward center drives much of teenagers’ risky behavior. This behavioral paradox also helps explain why adolescents are particularly prone to injury and trauma. The top three killers of teenagers are accidents, homicide and suicide.
  • ...10 more annotations...
  • The brain-development lag has huge implications for how we think about anxiety and how we treat it. It suggests that anxious adolescents may not be very responsive to psychotherapy that attempts to teach them to be unafraid, like cognitive behavior therapy
  • should also make us think twice — and then some — about the ever rising use of stimulants in young people, because these drugs may worsen anxiety and make it harder for teenagers to do what they are developmentally supposed to do: learn to be unafraid when it is appropriate
  • up to 20 percent of adolescents in the United States experience a diagnosable anxiety disorder, like generalized anxiety or panic attacks, probably resulting from a mix of genetic factors and environmental influences.
  • This isn’t to say that cognitive therapy is ineffective for teenagers, but that because of their relative difficulty in learning to be unafraid, it may not be the most effective treatment when used on its own.
  • Fear learning lies at the heart of anxiety and anxiety disorders. This primitive form of learning allows us to form associations between events and specific cues and environments that may predict danger.
  • once previously threatening cues or situations become safe, we have to be able to re-evaluate them and suppress our learned fear associations. People with anxiety disorders have trouble doing this and experience persistent fear in the absence of threat — better known as anxiety.
  • Dr. Casey discovered that adolescents had a much harder time “unlearning” the link between the colored square and the noise than children or adults did.
  • adolescents had trouble learning that a cue that was previously linked to something aversive was now neutral and “safe.” If you consider that adolescence is a time of exploration when young people develop greater autonomy, an enhanced capacity for fear and a more tenacious memory for threatening situations are adaptive and would confer survival advantage. In fact, the developmental gap between the amygdala and the prefrontal cortex that is described in humans has been found across mammalian species, suggesting that this is an evolutionary advantage.
  • As a psychiatrist, I’ve treated many adults with various anxiety disorders, nearly all of whom trace the origin of the problem to their teenage years. They typically report an uneventful childhood rudely interrupted by adolescent anxiety. For many, the anxiety was inexplicable and came out of nowhere.
  • prescription sales for stimulants increased more than fivefold between 2002 and 2012. This is of potential concern because it is well known from both human and animal studies that stimulants enhance learning and, in particular, fear conditioning.

The Trouble With Brain Science - NYTimes.com - 0 views

  • What would a good theory of the brain actually look like?
  • Different kinds of sciences call for different kinds of theories. Physicists, for example, are searching for a “grand unified theory” that integrates gravity, electromagnetism and the strong and weak nuclear forces into a neat package of equations.
  • The living world is bursting with variety and unpredictable complexity, because biology is the product of historical accidents, with species solving problems based on happenstance that leads them down one evolutionary road rather than another.
  • ...4 more annotations...
  • ut biological complexity is only part of the challenge in figuring out what kind of theory of the brain we’re seeking.
  • What we are really looking for is a bridge, some way of connecting two separate scientific languages — those of neuroscience and psychology.
  • An example is the discovery of DNA, which allowed us to understand how genetic information could be represented and replicated in a physical structure. In one stroke, this bridge transformed biology from a mystery — in which the physical basis of life was almost entirely unknown — into a tractable if challenging set of problems
  • We know that there must be some lawful relation between assemblies of neurons and the elements of thought, but we are currently at a loss to describe those laws.

Evolution and the American Myth of the Individual - NYTimes.com - 0 views

  • the country’s two main political parties have “fundamental philosophical differences.” But what exactly does that mean?
  • In a broad sense, Democrats, particularly the more liberal among them, are more likely to embrace the communal nature of individual lives and to strive for policies that emphasize that understanding.
  • Republicans, especially libertarians and Tea Party members on the ideological fringe, however, often trace their ideas about freedom and liberty back to Enlightenment thinkers of the 17th and 18th centuries, who argued that the individual is the true measure of human value, and each of us is naturally entitled to act in our own best interests free of interference by others. Self-described libertarians generally also pride themselves on their high valuation of logic and reasoning over emotion.
  • ...13 more annotations...
  • Philosophers from Aristotle to Hegel have emphasized that human beings are essentially social creatures, that the idea of an isolated individual is a misleading abstraction. So it is not just ironic but instructive that modern evolutionary research, anthropology, cognitive psychology and neuroscience have come down on the side of the philosophers who have argued that the basic unit of human social life is not and never has been the selfish, self-serving individual.
  • The irony here is that when it comes to our responsibilities to one another as human beings, religion and evolution nowadays are not necessarily on opposite sides of the fence.
  • in the eyes of many conservative Americans today, religion and evolution do not mix. You either accept what the Bible tells us or what Charles Darwin wrote, but not both
  • Contrary to libertarian and Tea Party rhetoric, evolution has made us a powerfully social species, so much so that the essential precondition of human survival is and always has been the individual plus his or her relationships with others.
  • as Matthew D. Lieberman, a social neuroscience researcher at the University of California, Los Angeles, has written: “we think people are built to maximize their own pleasure and minimize their own pain. In reality, we are actually built to overcome our own pleasure and increase our own pain in the service of following society’s norms.”
  • Why then did Rousseau and others make up stories about human history if they didn’t really believe them? The simple answer, at least during the Enlightenment, was that they wanted people to accept their claim that civilized life is based on social conventions, or contracts, drawn up at least figuratively speaking by free, sane and equal human beings — contracts that could and should be extended to cover the moral and working relationships that ought to pertain between rulers and the ruled.
  • Jean-Jacques Rousseau famously declared in “The Social Contract” (1762) that each of us is born free and yet everywhere we are in chains. He did not mean physical chains. He meant social ones. We now know he was dead wrong. Human evolution has made us obligate social creatures. Even if some of us may choose sooner or later to disappear into the woods or sit on a mountaintop in deep meditation, we humans are able to do so only if before such individualistic anti-social resolve we have first been socially nurtured and socially taught survival arts by others. The distinction Rousseau and others tried to draw between “natural liberty, which is bounded only by the strength of the individual” and “civil liberty, which is limited by the general will” is fanciful, not factual.
  • In short, their aims were political, not historical, scientific or religious.
  • what Rousseau and others crafted as arguments in favor of their ideas all had the earmarks of primitive mythology
  • Bronislaw Malinowski argued almost a century ago: “Myth fulfills in primitive culture an indispensable function: it expresses, enhances, and codifies belief, it safeguards and enforces morality, it vouches for the efficiency of ritual and contains practical rules for the guidance of man.”
  • not all myths make good charters for faith and wisdom. The sanctification of the rights of individuals and their liberties today by libertarians and Tea Party conservatives is contrary to our evolved human nature as social animals. There was never a time in history before civil society when we were each totally free to do whatever we elected to do. We have always been social and caring creatures. The thought that it is both rational and natural for each of us to care only for ourselves, our own preservation, and our own achievements is a treacherous fabrication. This is not how we got to be the kind of species we are today.
  • Myths achieve this social function, he observed, by serving as guides, or charters, for moral values, social order and magical belief.
  • Nor is this what the world’s religions would ask us to believe.

From Sports Illustrated, the Latest Body Part for Women to Fix - NYTimes.com - 0 views

  • At 44, I am old enough to remember when reconstruction was something you read about in history class, when a muffin top was something delicious you ate at the bakery, a six-pack was how you bought your beer, camel toe was something one might glimpse at the zoo, a Brazilian was someone from the largest country in South America and terms like thigh gap and bikini bridge would be met with blank looks.
  • Now, each year brings a new term for an unruly bit of body that women are expected to subdue through diet and exercise.

  • As a graphic designer and Photoshop teacher, I also have to note that Photoshop is used HEAVILY in these kinds of publications. Even on women with incredibly beautiful (by pop culture standards) bodies. It's quite sad because the imagery we're expected to live up to (or approximate) by cultural standards, is illustration. It's not even real. My boyfriend and I had a big laugh over a Playboy cover a few months ago where the Photoshopping was so extreme (thigh gap and butt cheek) it was anatomically impossible and looked ridiculous. I work in the industry.. I know what the Liquify filter and the Spot Healing Brush can do!
  • We may harp on gender inequality while pursuing stupid fetishes. Well into our middle age, we still try to forcefully wriggle into size 2 pair of jeans. We foolishly spend tonnes of money on fake ( these guys should be sued for false advertising )age -defying, anti-wrinkle creams. Why do we have to have our fuzz and bush diappear while the men have forests on their chests,abdomens,butts, arms and legs? For that we have only ourselves to blame. We just cannot get out of this mindset of being objectified. And we pass on these foolishness to our daughters and grand-daughters. They get trapped, never satisfied with what they see in the mirror. Don't expect the men to change anytime soon. They will always maintain the status quo. It is for us, women to get out of this rut. We have to 'snatch' gender-equality. It will never be handed to us. PERIOD
  • I spent years dieting and exercising to look good--or really to not look bad. I knew the calories (and probably still do) in thousands of foods. How I regret the time I spent on that and the boyfriends who cared about that. And how much more I had to give to the world. With unprecedented economic injustice, ecosystems collapsing, war breaking out everywhere, nations going under water, people starving in refugee camps, the keys to life, behavior, and disease being unlocked in the biological sciences . . . this is what we think women should spend their time worrying about? Talk about a poverty of ambition. No more. Won't even look at these demeaning magazines when I get my hair cut. If that's what a woman cares about, I try to tell her to stop wasting her time. If that's what a man cares about, he is a waste of my time. What a depressing way to distract women from achieving more in this world. Really wish I'd know this at 12.
  • we believe we're all competing against one another to procreate and participate in evolution. So women (and men) compete ferociously, and body image is a subset of all that. Then there's LeMarckian evolutionary theory and epigenetics...http://en.wikipedia.org/wiki/Lamarckismhttp://en.wikipedia.org/wiki/EpigeneticsBottom line is that we can't stop this train any more easily than we can stop the anthropocene's Climate Change.

The truth about Darwin and God - Salon.com - 0 views

  • as Darwin himself often confessed, natural selection cannot work without prior variations in the organisms that will be selected or not for survival.
  • whatever “Darwinism” is, this is not a book about Darwinism. Nor is it a book about contemporary evolutionary theory or the “new synthesis” or the “extended synthesis.” It is rather a book about “chance” in Darwin’s writing. To that extent it must confront “Darwinism” more broadly, even in its recent and contemporary incarnations, if only to situate the problems it deals with in a proper context.
  • My view is that “Darwinism” had a single meaning to Darwin from beginning to end. Yes, changes were made in exposition, over and over again, and in one sense, as a philosophical platitude, one cannot change one’s way of saying something without changing what one says, and therefore what one is taken to mean.
  • ...3 more annotations...
  • An examination of the Darwinian corpus shows that many of the most important changes centered on how he wished to present the role of “chance” in evolution to an ever-expanding reading public, especially after the Origin first appeared.
  • But I try to set out and move through with a clean slate, basing my claims on Darwin’s ipsissima verba rather than on what others have said.
  • The earth, its geological features, and its organic inhabitants are here only through lucky accidents? For many people that was a hard pill to swallow. Darwin did accept it, but also knew he would have to get his audience to accept it too if he were to succeed in establishing his theory as the correct account of the origin of species.

What Are You So Afraid Of? - NYTimes.com - 2 views

  • We have clear directives about what is really worth our fear. Participants in the real parade of horrors include radical changes in the carbon cycle, the rate of species extinction, extreme weather, genetically modified food, institutional financial misconduct that puts our security at risk. The archive of very real menaces threatening us now is so full, it would seem we hardly know how to choose what to be scared of.
  • Except that we do choose, and what we choose are generally the ordinary fears such as heights, public speaking, insects, reptiles. They are all things that have about as much chance of harming us as the characters behind some of this season’s top trending scary costumes: zombies, werewolves and cast members from “Duck Dynasty.”
  • while we fear snakes, spiders, darkness, open spaces and closed spaces, we do not fear the more likely instruments of danger — knives, guns, cars, electrical sockets — because, he says, “our species has not been exposed to these lethal agents long enough in evolutionary time to have acquired the predisposing genes that ensure automatic avoidance.” Which is to say, fear, real fear, deep fear, the kind that changes our habits and actions, is not something on which we are likely to follow sensible instruction.

  • At a moment of such social, political and environmental urgency, I would like to think it is possible to tap into human fear to change behavior in some fundamental and strategic way. Yet what seems more likely to me is the possibility that fear is simply an unpredictable rogue impulse that all too often remains indifferent to the genuine threats around us. And that may be the scariest thing of all.

  • In American culture right now, as I say, the worldview that is ascendant may be described as posthumanism.
  • The posthumanism of the 1970s and 1980s was more insular, an academic affair of “theory,” an insurgency of professors; our posthumanism is a way of life, a social fate.

Assessing the Value of Buddhism, for Individuals and for the World - The New York Times - 0 views

  • Robert Wright sketches an answer early in “Why Buddhism Is True.” He settles on a credible blend that one might call Western Buddhism, a largely secular approach to life and its problems but not devoid of a spiritual dimension. The centerpiece of the approach is the practice of mindful meditation.
  • The goal of “Why Buddhism Is True” is ambitious: to demonstrate “that Buddhism’s diagnosis of the human predicament is fundamentally correct, and that its prescription is deeply valid and urgently important.”
  • It is reasonable to claim that Buddhism, with its focus on suffering, addresses critical aspects of the human predicament. It is also reasonable to suggest that the prescription it offers may be applicable and useful to resolve that predicament.
  • ...9 more annotations...
  • To produce his demonstrations and to support the idea that Buddhism is “true,” Wright relies on science, especially on evolutionary psychology, cognitive science and neuroscience.
  • Wright is up to the task: He’s a Buddhist who has written about religion and morality from a scientific perspective — he is most famous for his 1994 book, “The Moral Animal.”
  • Second, the mismatch between causes and responses is rooted in evolution. We have inherited from our nonhuman and human forerunners a complex affect apparatus suited to life circumstances very different from ours
  • First, the beneficial powers of meditation come from the possibility of realizing that our emotive reactions and the consequent feelings they engender — which operate in automated fashion, outside our deliberate control — are often inappropriate and even counterproductive relative to the situations that trigger them.
  • Third, meditation allows us to realize that the idea of the self as director of our decisions is an illusion, and that the degree to which we are at the mercy of a weakly controlled system places us at a considerable disadvantage
  • Fourth, the awareness brought on by meditation helps the construction of a truly enlightened humanity and counters the growing tribalism of contemporary societies.
  • when, in modern life, emotions such as fear and anger are incorrectly and unnecessarily engaged — for example, road rage — Wright calls the respective feelings “false” or “illusory.” Such feelings, however, are no less true than the thirst, hunger or pain that Wright accepts and welcomes
  • We can agree that mindful meditation promotes a distancing effect and thus may increase our chances of combining affect and reason advantageously. Meditation can help us glean the especially flawed and dislocated status of humans in modern societies, and help us see how social and political conflicts appear to provoke resentment and anger so easily.
  • How does one scale up, from many single individuals to populations, in time to prevent the social catastrophes that seem to be looming?

  • They’re finding that religion may, in fact, be a byproduct of the way our brains work, growing from cognitive tendencies to seek order from chaos, to anthropomorphize our environment and to believe the world around us was created for our use.
  • “Religion is one of the big ways that human societies have hit on as a solution to induce unrelated individuals to be nice to each other,” says Norenzayan.
  • “The problem is, the more you look inward toward your religious group and its claims of virtue, the less you look outward and the more distrustful you are of others,” he says.

  • That distrust causes much of the world’s strife and violence and is one of the reasons the “new atheists,” including British evolutionary biologist Richard Dawkins, PhD, and neuroscientist Sam Harris, PhD, want to see religion disappear.

    I find this article interesting because it analysis the reason of religion from the perspective of basic human nature.

The Triumph of Obama's Long Game - 0 views

  • Speaking of ideology versus reality, there is, it seems to me, a parallel on the left. That is the current attempt to deny the profound natural differences between men and women, and to assert, with a straight and usually angry face, that gender is in no way rooted in sex, and that sex is in no way rooted in biology.
  • This unscientific product of misandrist feminism and confused transgenderism is striding through the culture, and close to no one in the elite is prepared to resist it.
  • And so we have the establishment of gender-neutral birth certificates in Canada; and, in England, that lovely old phrase, “Ladies and Gentlemen,” is being removed from announcements on the Tube
  • ...20 more annotations...
  • We have dozens of new pronouns in colleges (for all those genders that have suddenly sprung into existence), and biological males competing in all-female high-school athletic teams (guess who wins at track).
  • Worse, we have constant admonitions against those who actually conform, as most human beings always have, to the general gender rule.
  • We have gone from rightly defending the minority to wrongly problematizing the majority. It should surprise no one that, at some point, the majority will find all of this, as Josh Barro recently explained, “annoying.”
  • I say this as someone happily in the minority — and who believes strongly in the right to subvert or adapt traditional gender roles.
  • But you can’t subvert something that you simultaneously argue doesn’t exist.
  • the core contradiction of ideological transgenderism. By severing the link between sex and gender completely, it abolishes the core natural framework without which the transgender experience makes no sense at all.
  • It’s also a subtle, if unintentional, attack on homosexuality. Most homosexuals are strongly attached to their own gender and attracted to traditional, natural expressions of it. That’s what makes us gay, for heaven’s sake. And that’s one reason the entire notion of a common “LGBT” identity is so misleading. How can a single identity comprise both the abolition of gender and at the same time its celebration?
  • Exceptions, in other words, need a rule to exist. Abolish gender’s roots in biology and sex — and you abolish gay people and transgender people as well.
  • Yes, there’s a range of gender expression among those of the same sex. But it’s still tethered among most to the forces of chromosomes and hormones that make us irreducibly male and female. Nature can be interpreted; it can even be played with; but it cannot be abolished. After all, how can you be “queer” if there is no such thing as “normal”?
  • Transgender people exist and should be treated with absolutely the same human respect, decency, and civil equality as anyone else. But they don’t disprove traditional notions of gender as such — which have existed in all times, places, and cultures in human history and prehistory, and are rooted deeply in evolutionary biology and reproductive strategy.
  • Intersex people exist and, in my view, should not be genitally altered or “fixed” without their adult consent. But they do not somehow negate the overwhelming majority who have no such gender or sexual ambiguity.
  • the entire society does not need to be overhauled in order to make gay or trans experience central to it. Inclusion, yes. Revolution, no.
  • The added problem with this war on nature is the backlash it inevitably incurs. There’s a reason so many working-class men find it hard to vote for Democrats any more. And there’s a reason why a majority of white women last year voted for a man who boasted of sexual assault if the alternative was a triumph for contemporary left-feminism.
  • You can’t assault the core identity of most people’s lives and then expect them to vote for you. As a Trump supporter in Colorado just told a reporter from The New Yorker: “I’ve never been this emotionally invested in a political leader in my life. The more they hate him, the more I want him to succeed. Because what they hate about him is what they hate about me.”
  • One of the features you most associate with creeping authoritarianism is the criminalization of certain political positions. Is anything more anathema to a liberal democracy? If Trump were to suggest it, can you imagine the reaction?
  • And yet it’s apparently fine with a hefty plurality of the Senate and House. I’m referring to the remarkable bill introduced into the Congress earlier this year — with 237 sponsors and co-sponsors in the House and 43 in the Senate — which the ACLU and the Intercept have just brought to light. It’s a remarkably bipartisan effort, backed by Chuck Schumer and Ted Cruz, among many solid Trump-resisting Democrats and hard-line Republicans.
  • it would actually impose civil and criminal penalties on American citizens for backing or joining any international boycott of Israel because of its settlement activities. There are even penalties for simply inquiring about such a boycott. And they’re not messing around. The minimum civil penalty would be $250,000 and the maximum criminal penalty $1 million and 20 years in prison. Up to 20 years in prison for opposing the policies of a foreign government and doing something about it!
  • I’m not in favor of boycotting Israel when we don’t boycott, say, Saudi Arabia. But seriously: making it illegal?
  • Every now and again, you just have to sit back and admire the extraordinary skills of the Greater Israel lobby. You’ve never heard of this bill, and I hadn’t either. But that is partly the point. AIPAC doesn’t want the attention — writers who notice this attempted assault on a free society will be tarred as anti-Semites (go ahead, it wouldn’t be the first time) and politicians who resist it will see their careers suddenly stalled.
  • pointing out this special interest’s distortion of democracy is not the equivalent of bigotry. It’s simply a defense of our democratic way of life.

Buddhism Is More 'Western' Than You Think - The New York Times - 0 views

  • Not only have Buddhist thinkers for millenniums been making very much the kinds of claims that Western philosophers and psychologists make — many of these claims are looking good in light of modern Western thought.
  • In fact, in some cases Buddhist thought anticipated Western thought, grasping things about the human mind, and its habitual misperception of reality, that modern psychology is only now coming to appreciate.
  • “Things exist but they are not real.” I agree with Gopnik that this sentence seems a bit hard to unpack. But if you go look at the book it is taken from, you’ll find that the author himself, Mu Soeng, does a good job of unpacking it.
  • ...14 more annotations...
  • It turns out Soeng is explaining an idea that is central to Buddhist philosophy: “not self” — the idea that your “self,” as you intuitively conceive it, is actually an illusion. Soeng writes that the doctrine of not-self doesn’t deny an “existential personality” — it doesn’t deny that there is a you that exists; what it denies is that somewhere within you is an “abiding core,” a kind of essence-of-you that remains constant amid the flux of thoughts, feelings, perceptions and other elements that constitute your experience. So if by “you” we mean a “self” that features an enduring essence, then you aren’t real.
  • In recent decades, important aspects of the Buddhist concept of not-self have gotten support from psychology. In particular, psychology has bolstered Buddhism’s doubts about our intuition of what you might call the “C.E.O. self” — our sense that the conscious “self” is the initiator of thought and action.
  • recognizing that “you” are not in control, that you are not a C.E.O., can help give “you” more control. Or, at least, you can behave more like a C.E.O. is expected to behave: more rationally, more wisely, more reflectively; less emotionally, less rashly, less reactively.
  • Suppose that, via mindfulness meditation, you observe a feeling like anxiety or anger and, rather than let it draw you into a whole train of anxious or angry thoughts, you let it pass away. Though you experience the feeling — and in a sense experience it more fully than usual — you experience it with “non-attachment” and so evade its grip. And you now see the thoughts that accompanied it in a new light — they no longer seem like trustworthy emanations from some “I” but rather as transient notions accompanying transient feelings.
  • Brain-scan studies have produced tentative evidence that this lusting and disliking — embracing thoughts that feel good and rejecting thoughts that feel bad — lies near the heart of certain “cognitive biases.” If such evidence continues to accumulate, the Buddhist assertion that a clear view of the world involves letting go of these lusts and dislikes will have drawn a measure of support from modern science.
  • Note how, in addition to being therapeutic, this clarifies your view of the world. After all, the “anxious” or “angry” trains of thought you avoid probably aren’t objectively true. They probably involve either imagining things that haven’t happened or making subjective judgments about things that have.
  • the Buddhist idea of “not-self” grows out of the belief undergirding this mission — that the world is pervasively governed by causal laws. The reason there is no “abiding core” within us is that the ever-changing forces that impinge on us — the sights, the sounds, the smells, the tastes — are constantly setting off chain reactions inside of us.
  • Buddhism’s doubts about the distinctness and solidity of the “self” — and of other things, for that matter — rests on a recognition of the sense in which pervasive causality means pervasive fluidity.
  • Buddhism long ago generated insights that modern psychology is only now catching up to, and these go beyond doubts about the C.E.O. self.
  • psychology has lately started to let go of its once-sharp distinction between “cognitive” and “affective” parts of the mind; it has started to see that feelings are so finely intertwined with thoughts as to be part of their very coloration. This wouldn’t qualify as breaking news in Buddhist circles.
  • There’s a broader and deeper sense in which Buddhist thought is more “Western” than stereotype suggests. What, after all, is more Western than science’s emphasis on causality, on figuring out what causes what, and hoping to thus explain why all things do the things they do?
  • All we can do is clear away as many impediments to comprehension as possible. Science has a way of doing that — by insisting that entrants in its “competitive storytelling” demonstrate explanatory power in ways that are publicly observable, thus neutralizing, to the extent possible, subjective biases that might otherwise prevail.
  • Buddhism has a different way of doing it: via meditative disciplines that are designed to attack subjective biases at the source, yielding a clearer view of both the mind itself and the world beyond it.
  • The results of these two inquiries converge to a remarkable extent — an extent that can be appreciated only in light of the last few decades of progress in psychology and evolutionary science. At least, that’s my argument.

Teenagers, Anxiety Can Be Your Friend - The New York Times - 0 views

  • A new report from the University of Michigan’s C.S. Mott Children’s Hospital National Poll on Children’s Health found that one in three teen girls and one in five teen boys have experienced new or worsening anxiety since March 2020.
  • You might be feeling tense about where things stand with your friends or perhaps you’re on edge about something else altogether: your family, your schoolwork, your future, the health of the planet.
  • But the discomfort of anxiety has a basic evolutionary function: to get us to tune into the fact that something’s not right.
  • ...10 more annotations...
  • That odd feeling in the pit of your stomach will help you to consider the situation carefully and be cautious about your next step.
  • It’s more often a friend than a foe, one that will help you notice when things are on the wrong track.
  • psychologists agree that anxiety becomes a problem if its alarm makes no sense — either going off for no reason or blaring when a chime would do.
  • Feeling a little tense before a big game is appropriate and may even improve your performance. Having a panic attack on the sidelines means your anxiety has gone too far.
  • At the physical level, the amygdala, a primitive structure in the brain, detects a threat and sends the heart and lungs into overdrive getting your body ready to fight or flee that threat.
  • Though it can sound like a daffy approach to managing tension, breathing deeply and slowly activates a powerful part of the nervous system responsible for resetting the body to its pre-anxiety state.
  • Am I overestimating the severity of the problem I’m facing? Am I underestimating my power to manage it?
  • It’s human nature to want to repeat any behavior that leads to feelings of pleasure or comfort, but every boost of avoidance-related relief increases the likelihood that you’ll want to continue to avoid what you fear.
  • For example, the realities of in-person school are sure to be more manageable than the harrowing scenarios your imagination can create.
  • Knowing what’s true about anxiety — and not — will make it easier to navigate the uncertain times ahead.

Frontiers | A Neural Network Framework for Cognitive Bias | Psychology - 0 views

  • Human decision-making shows systematic simplifications and deviations from the tenets of rationality (‘heuristics’) that may lead to suboptimal decisional outcomes (‘cognitive biases’). There are currently three prevailing theoretical perspectives on the origin of heuristics and cognitive biases: a cognitive-psychological, an ecological and an evolutionary perspective. However, these perspectives are mainly descriptive and none of them provides an overall explanatory framework for
  • the underlying mechanisms of cognitive biases. To enhance our understanding of cognitive heuristics and biases we propose a neural network framework for cognitive biases, which explains why our brain systematically tends to default to heuristic (‘Type 1’) decision making. We argue that many cognitive biases arise from intrinsic brain mechanisms that are fundamental for the working of biological neural networks. To substantiate our viewpoint, we discern and explain four basic neural network principles: (1) Association, (2) Compatibility, (3) Retainment, and (4) Focus. These principles are inherent to (all) neural networks which were originally optimized to perform concrete biological, perceptual, and motor functions. They form the basis for our inclinations to associate and combine (unrelated) information, to prioritize information that is compatible with our present state (such as knowledge, opinions, and expectations), to retain given information that sometimes could better be ignored, and to focus on dominant information while ignoring relevant information that is not directly activated. The supposed mechanisms are complementary and not mutually exclusive. For different cognitive biases they may all contribute in varying degrees to distortion of information. The present viewpoint not only complements the earlier three viewpoints, but also provides a unifying and binding framework for many cognitive bias phenomena.
  • The cognitive-psychological (or heuristics and biases) perspective (Evans, 2008; Kahneman and Klein, 2009) attributes cognitive biases to limitations in the available data and in the human information processing capacity (Simon, 1955; Broadbent, 1958; Kahneman, 1973, 2003; Norman and Bobrow, 1975)

How History Gets Things Wrong: The Neuroscience of Our Addiction to Stories | Reviews | Notre Dame Philosophical Reviews | University of Notre Dame - 1 views

  • In this book, Rosenberg elaborates further such arguments to take issue with historical narratives and, more generally, with the way in which we most pervasively make sense of people's actions and motivations through narratives.
  • His main contention is that such narratives are always wrong or, to put it differently, that they can't possibly be right.
  • Rosenberg argues that neuroscience itself, our only reliable method to study psychological capacities, shows that theory of mind's posits do not exist
  • ...12 more annotations...
  • The reason is that the best available evidence on how the brain works shows that the brain does not deal with the kind of things that beliefs and desires are supposed to trade with: contents.
  • When we believe or desire, something is believed or desired: that I have bread, that it rains, that the Parliament passes the bill, etc. Beliefs and desires are about something.
  • . After being presented with the assassin and the crime, the book moves on to explain why, even if always wrong, narratives in general, and historical narratives in particular, are so compelling for us. Even if we have no claim to truth or correctness for our narratives, narratives seem to be highly convincing in moving us to act
  • Furthermore, we cannot but think in terms of them. Rosenberg's explanation for this 'addiction to stories' is that it has been entrenched in us by evolutionary processes that took place over the last million years of natural history
  • Narrative explanations emerged out of Darwinian processes of natural selection -- or "environmental filtration", in the less purposive parlance Rosenberg prefers -- that allowed our ancestors to coordinate efforts, collaborate and flourish, moving from the bottom to the top of the Pleistocene's food chain. Rosenberg argues that while the basic mechanisms of mindreading pervasive in the animal kingdom, based on mutual tracking and monitoring of animals' behavior, are a sound method for getting agents to coordinate behavior, these mechanisms' more recent successor, the theory of mind, crafted by the use of co-evolved languages, turned those mindreading abilities into a theory with empirical hypothesis about agents' beliefs and desires but no facts to match them.
  • The error historians allegedly make lies in mistaking stories for real explanations, surmising that behind our behavior there are purposes, rational motivations.
  • Historians -- in particular narrative historians -- make a pervasive use of folk psychological explanations, i.e., explanations that describe events in terms of the beliefs and desires of historical agents, including individuals and groups.
  • In order for folk psychological and historical narratives to be right there have to be facts of the matter about what sentences in such explanation refer to that make them true.
  • Folk psychological explanations of actions in terms of platitudes about beliefs and desires pairings evolved in natural history closely related to mind-reading mechanisms that allowed our ancestors to deal with cooperation and coordination problems.
  • There are no interpretative mechanisms in the brain (at any level of description) that can vindicate the attribution of contents to beliefs and desires.
  • There are no facts of the matter that allow us to select belief/desire pairings as those actually operating 'behind' an agent's behavior.
  • Folk psychological explanations do not track any facts and thus can't be correct.

Opinion | Your Brain Is Not for Thinking - The New York Times - 0 views

  • This new activity of hunting started an evolutionary arms race. Over millions of years, both predators and prey evolved more complex bodies that could sense and move more effectively to catch or elude other creatures.
  • Eventually, some creatures evolved a command center to run those complex bodies. We call it a brain.
  • Your brain’s most important job isn’t thinking; it’s running the systems of your body to keep you alive and well. According to recent findings in neuroscience, even when your brain does produce conscious thoughts and feelings, they are more in service to the needs of managing your body than you realize.
  • ...8 more annotations...
  • Much of your brain’s activity happens outside your awareness. In every moment, your brain must figure out your body’s needs for the next moment and execute a plan to fill those needs in advance.
  • The budget for your body tracks resources
  • Each action that spends resources, such as standing up, running, and learning, is like a withdrawal from your account. Actions that replenish your resources, such as eating and sleeping, are like deposits.
  • Every thought you have, every feeling of happiness or anger or awe you experience, every kindness you extend and every insult you bear or sling is part of your brain’s calculations as it anticipates and budgets your metabolic needs.
  • This view of the brain has many implications for understanding human beings. So often, for example, we conceive of ourselves in mental terms, separate from the physical
  • There is no such thing as a purely mental cause, because every mental experience has roots in the physical budgeting of your body
  • When an unpleasant thought pops into your head, like “I can’t take this craziness anymore,” ask yourself body-budgeting questions. “Did I get enough sleep last night? Am I dehydrated? Should I take a walk? Call a friend? Because I could use a deposit or two in my body budget.”
  • I’m suggesting that it’s possible to acknowledge what your brain is actually doing and take some comfort from it. Your brain is not for thinking. Everything that it conjures, from thoughts to emotions to dreams, is in the service of body budgeting. This perspective, adopted judiciously, can be a source of resilience in challenging times.
