  • Trump didn't elaborate on Amazon's tax figures. He actually didn't cite any.
  • Trump's claims don't really hold up.
  • Amazon paid $167 million in income taxes in 2014 -- the first full year after Bezos acquired the paper. And that was despite the fact that Amazon reported a pre-tax loss in 2014.
  • So Trump is wrong when he said that Amazon is unprofitable.

  • "The threat is real!" Yerushalmi concluded. "Sharia is not a peaceful, feel-good Islam."

Science and gun violence: why is the research so weak? [Part 2] - Boing Boing - 1 views

  • Scientists are missing some important bits of data that would help them better understand the effects of gun policy and the causes of gun-related violence. But that’s not the only reason why we don’t have solid answers. Once you have the data, you still have to figure out what it means. This is where the research gets complicated, because the problem isn’t simply about what we do and don’t know right now. The problem, say some scientists, is that we —from the public, to politicians, to even scientists themselves—may be trying to force research to give a type of answer that we can’t reasonably expect it to offer. To understand what science can do for the gun debates, we might have to rethink what “evidence-based policy” means to us.
  • For the most part, there aren’t a lot of differences in the data that these studies are using. So how can they reach such drastically different conclusions? The issue is in the kind of data that exists, and what you have to do to understand it, says Charles Manski, professor of economics at Northwestern University. Manski studies the ways that other scientists do research and how that research translates into public policy.
  • Even if we did have those gaps filled in, Manski said, what we’d have would still just be observational data, not experimental data. “We don’t have randomized, controlled experiments, here,” he said. “The only way you could do that, you’d have to assign a gun to some people randomly at birth and follow them throughout their lives. Obviously, that’s not something that’s going to work.”
  • ...14 more annotations...
  • This means that, even under the best circumstances, scientists can’t directly test what the results of a given gun policy are. The best you can do is to compare what was happening in a state before and after a policy was enacted, or to compare two different states, one that has the policy and one that doesn’t. And that’s a pretty inexact way of working.
  • Add in enough assumptions, and you can eventually come up with an estimate. But is the estimate correct? Is it even close to reality? That’s a hard question to answer, because the assumptions you made—the correlations you drew between cause and effect, what you know and what you assume to be true because of that—might be totally wrong.
  • It’s hard to tease apart the effect of one specific change, compared to the effects of other things that could be happening at the same time.
  • This process of taking the observational data we do have and then running it through a filter of assumptions plays out in the real world in the form of statistical modeling. When the NAS report says that nobody yet knows whether more guns lead to more crime, or less crime, what they mean is that the models and the assumptions built into those models are all still proving to be pretty weak.
  • From either side of the debate, he said, scientists continue to produce wildly different conclusions using the same data. On either side, small shifts in the assumptions lead the models to produce different results. Both factions continue to choose sets of assumptions that aren’t terribly logical. It’s as if you decided that anybody with blue shoes probably had a belly-button piercing. There’s not really a good reason for making that correlation. And if you change the assumption—actually, belly-button piercings are more common in people who wear green shoes—you end up with completely different results.
  • The Intergovernmental Panel on Climate Change (IPCC) produces these big reports periodically, which analyze lots of individual papers. In essence, they’re looking at lots of trees and trying to paint you a picture of the forest. IPCC reports are available for free online, you can go and read them yourself. When you do, you’ll notice something interesting about the way that the reports present results. The IPCC never says, “Because we burned fossil fuels and emitted carbon dioxide into the atmosphere then the Earth will warm by x degrees.” Instead, those reports present a range of possible outcomes … for everything. Depending on the different models used, different scenarios presented, and the different assumptions made, the temperature of the Earth might increase by anywhere between 1.5 and 4.5 degrees Celsius.
  • What you’re left with is an environment where it’s really easy to prove that your colleague’s results are probably wrong, and it’s easy for him to prove that yours are probably wrong. But it’s not easy for either of you to make a compelling case for why you’re right.
  • Statistical modeling isn’t unique to gun research. It just happens to be particularly messy in this field. Scientists who study other topics have done a better job of using stronger assumptions and of building models that can’t be upended by changing one small, seemingly randomly chosen detail. It’s not that, in these other fields, there’s only one model being used, or even that all the different models produce the exact same results. But the models are stronger and, more importantly, the scientists do a better job of presenting the differences between models and drawing meaning from them.
  • “Climate change is one of the rare scientific literatures that has actually faced up to this,” Charles Manski said. What he means is that, when scientists model climate change, they don’t expect to produce exact, to-the-decimal-point answers.
  • “It’s been a complete waste of time, because we can’t validate one model versus another,” Pepper said. Most likely, he thinks that all of them are wrong. For instance, all the models he’s seen assume that a law will affect every state in the same way, and every person within that state in the same way. “But if you think about it, that’s just nonsensical,” he said.
  • On the one hand, that leaves politicians in a bit of a lurch. The response you might mount to counteract a 1.5 degree increase in global average temperature is pretty different from the response you’d have to 4.5 degrees. On the other hand, the range does tell us something valuable: the temperature is increasing.
  • The problem with this is that it flies in the face of what most of us expect science to do for public policy. Politics is inherently biased, right? The solutions that people come up with are driven by their ideologies. Science is supposed to cut that Gordian Knot. It’s supposed to lay the evidence down on the table and impartially determine who is right and who is wrong.
  • Manski and Pepper say that this is where we need to rethink what we expect science to do. Science, they say, isn’t here to stop all political debate in its tracks. In a situation like this, it simply can’t provide a detailed enough answer to do that—not unless you’re comfortable with detailed answers that are easily called into question and disproven by somebody else with a detailed answer.
  • Instead, science can reliably produce a range of possible outcomes, but it’s still up to the politicians (and, by extension, up to us) to hash out compromises between wildly differing values on controversial subjects. When it comes to complex social issues like gun ownership and gun violence, science doesn’t mean you get to blow off your political opponents and stake a claim on truth. Chances are, the closest we can get to the truth is a range that encompasses the beliefs of many different groups.

The Man Who Would Teach Machines to Think - James Somers - The Atlantic - 1 views

  • Douglas Hofstadter, the Pulitzer Prize–winning author of Gödel, Escher, Bach, thinks we've lost sight of what artificial intelligence really means. His stubborn quest to replicate the human mind.
  • “If somebody meant by artificial intelligence the attempt to understand the mind, or to create something human-like, they might say—maybe they wouldn’t go this far—but they might say this is some of the only good work that’s ever been done
  • Their operating premise is simple: the mind is a very unusual piece of software, and the best way to understand how a piece of software works is to write it yourself.
  • ...43 more annotations...
  • “It depends on what you mean by artificial intelligence.”
  • Computers are flexible enough to model the strange evolved convolutions of our thought, and yet responsive only to precise instructions. So if the endeavor succeeds, it will be a double victory: we will finally come to know the exact mechanics of our selves—and we’ll have made intelligent machines.
  • Ever since he was about 14, when he found out that his youngest sister, Molly, couldn’t understand language, because she “had something deeply wrong with her brain” (her neurological condition probably dated from birth, and was never diagnosed), he had been quietly obsessed by the relation of mind to matter.
  • How could consciousness be physical? How could a few pounds of gray gelatin give rise to our very thoughts and selves?
  • Consciousness, Hofstadter wanted to say, emerged via just the same kind of “level-crossing feedback loop.”
  • In 1931, the Austrian-born logician Kurt Gödel had famously shown how a mathematical system could make statements not just about numbers but about the system itself.
  • But then AI changed, and Hofstadter didn’t change with it, and for that he all but disappeared.
  • By the early 1980s, the pressure was great enough that AI, which had begun as an endeavor to answer yes to Alan Turing’s famous question, “Can machines think?,” started to mature—or mutate, depending on your point of view—into a subfield of software engineering, driven by applications.
  • Take Deep Blue, the IBM supercomputer that bested the chess grandmaster Garry Kasparov. Deep Blue won by brute force.
  • Hofstadter wanted to ask: Why conquer a task if there’s no insight to be had from the victory? “Okay,” he says, “Deep Blue plays very good chess—so what? Does that tell you something about how we play chess? No. Does it tell you about how Kasparov envisions, understands a chessboard?”
  • AI started working when it ditched humans as a model, because it ditched them. That’s the thrust of the analogy: Airplanes don’t flap their wings; why should computers think?
  • It’s a compelling point. But it loses some bite when you consider what we want: a Google that knows, in the way a human would know, what you really mean when you search for something

  • s “an A,” you see a hunk of wood as “a table,” you see a meeting as “an emperor-has-no-clothes situation” and a friend’s pouting as “sour grapes”
  • That’s what it means to understand. But how does understanding work?
  • analogy is “the fuel and fire of thinking,” the bread and butter of our daily mental lives.
  • there’s an analogy, a mental leap so stunningly complex that it’s a computational miracle: somehow your brain is able to strip any remark of the irrelevant surface details and extract its gist, its “skeletal essence,” and retrieve, from your own repertoire of ideas and experiences, the story or remark that best relates.
  • in Hofstadter’s telling, the story goes like this: when everybody else in AI started building products, he and his team, as his friend, the philosopher Daniel Dennett, wrote, “patiently, systematically, brilliantly,” way out of the light of day, chipped away at the real problem. “Very few people are interested in how human intelligence works,”
  • For more than 30 years, Hofstadter has worked as a professor at Indiana University at Bloomington
  • The quick unconscious chaos of a mind can be slowed down on the computer, or rewound, paused, even edited
  • project out of IBM called Candide. The idea behind Candide, a machine-translation system, was to start by admitting that the rules-based approach requires too deep an understanding of how language is produced; how semantics, syntax, and morphology work; and how words commingle in sentences and combine into paragraphs—to say nothing of understanding the ideas for which those words are merely conduits.
  • , Hofstadter directs the Fluid Analogies Research Group, affectionately known as FARG.
  • Parts of a program can be selectively isolated to see how it functions without them; parameters can be changed to see how performance improves or degrades. When the computer surprises you—whether by being especially creative or especially dim-witted—you can see exactly why.
  • When you read Fluid Concepts and Creative Analogies: Computer Models of the Fundamental Mechanisms of Thought, which describes in detail this architecture and the logic and mechanics of the programs that use it, you wonder whether maybe Hofstadter got famous for the wrong book.
  • ut very few people, even admirers of GEB, know about the book or the programs it describes. And maybe that’s because FARG’s programs are almost ostentatiously impractical. Because they operate in tiny, seemingly childish “microdomains.” Because there is no task they perform better than a human.
  • “The entire effort of artificial intelligence is essentially a fight against computers’ rigidity.”
  • “Nobody is a very reliable guide concerning activities in their mind that are, by definition, subconscious,” he once wrote. “This is what makes vast collections of errors so important. In an isolated error, the mechanisms involved yield only slight traces of themselves; however, in a large collection, vast numbers of such slight traces exist, collectively adding up to strong evidence for (and against) particular mechanisms.
  • So IBM threw that approach out the window. What the developers did instead was brilliant, but so straightforward,
  • The technique is called “machine learning.” The goal is to make a device that takes an English sentence as input and spits out a French sentence
  • What you do is feed the machine English sentences whose French translations you already know. (Candide, for example, used 2.2 million pairs of sentences, mostly from the bilingual proceedings of Canadian parliamentary debates.)
  • By repeating this process with millions of pairs of sentences, you will gradually calibrate your machine, to the point where you’ll be able to enter a sentence whose translation you don’t know and get a reasonable resul
  • Google Translate team can be made up of people who don’t speak most of the languages their application translates. “It’s a bang-for-your-buck argument,” Estelle says. “You probably want to hire more engineers instead” of native speakers.
  • But the need to serve 1 billion customers has a way of forcing the company to trade understanding for expediency. You don’t have to push Google Translate very far to see the compromises its developers have made for coverage, and speed, and ease of engineering. Although Google Translate captures, in its way, the products of human intelligence, it isn’t intelligent itself.
  • “Did we sit down when we built Watson and try to model human cognition?” Dave Ferrucci, who led the Watson team at IBM, pauses for emphasis. “Absolutely not. We just tried to create a machine that could win at Jeopardy.”
  • For Ferrucci, the definition of intelligence is simple: it’s what a program can do. Deep Blue was intelligent because it could beat Garry Kasparov at chess. Watson was intelligent because it could beat Ken Jennings at Jeopardy.
  • “There’s a limited number of things you can do as an individual, and I think when you dedicate your life to something, you’ve got to ask yourself the question: To what end? And I think at some point I asked myself that question, and what it came out to was, I’m fascinated by how the human mind works, it would be fantastic to understand cognition, I love to read books on it, I love to get a grip on it”—he called Hofstadter’s work inspiring—“but where am I going to go with it? Really what I want to do is build computer systems that do something.
  • Peter Norvig, one of Google’s directors of research, echoes Ferrucci almost exactly. “I thought he was tackling a really hard problem,” he told me about Hofstadter’s work. “And I guess I wanted to do an easier problem.”
  • Of course, the folly of being above the fray is that you’re also not a part of it
  • As our machines get faster and ingest more data, we allow ourselves to be dumber. Instead of wrestling with our hardest problems in earnest, we can just plug in billions of examples of them.
  • Hofstadter hasn’t been to an artificial-intelligence conference in 30 years. “There’s no communication between me and these people,” he says of his AI peers. “None. Zero. I don’t want to talk to colleagues that I find very, very intransigent and hard to convince of anything
  • Everything from plate tectonics to evolution—all those ideas, someone had to fight for them, because people didn’t agree with those ideas.
  • Academia is not an environment where you just sit in your bath and have ideas and expect everyone to run around getting excited. It’s possible that in 50 years’ time we’ll say, ‘We really should have listened more to Doug Hofstadter.’ But it’s incumbent on every scientist to at least think about what is needed to get people to understand the ideas.”

Science Can't Prove Anything - Proslogion - 1 views

  • Science Can’t Prove Anything Aug.11,2011 Sir Karl Popper's foundational work, The Logic of Scientific Discovery, makes it clear that science cannot prove anything (click for credit)In one of my science textbooks, I make the statement that science cannot prove anything.1 I am always surprised at how controversial such a matter-of-fact statement is to some people. Almost every year, at least one student or parent will contact me simply aghast that I would write something like that in a science textbook. After all, science has proven all sorts of things, hasn’t it?
  • . I find myself frequently repeating to students and the public that science doesn’t “prove” theories. Scientific measurements can only disprove theories or be consistent with them. Any theory that is consistent with measurements could be disproved by a future measurement.

Review: Tegan and Sara's Album 'Love You to Death' Tinkers With Synth-Pop for Precise a... - 0 views

  • Listening closely to Tegan and Sara, the twin musicians enjoying unprecedented popularity two decades into their career due to 2013’s irresistible Heartthrob, can offer the kind of satisfaction that comes from solving a logic puzzle. Listening less closely can offer the same satisfaction great pop music always does. They bring a scientist’s rigor and an editor’s clarity to the stereotypically mushy topic of love, as well as, lately, to the synth-pop template they’ve helped repopularize on radio. Their trick is conveying lots of information—melodic, rhythmic, and lyrical—while maintaining simplicity and elegance.
  • The first track, “That Girl,” sets the album’s bittersweet tone in a very cool way. It’s about considering who you’ve become and not liking what you find—an extremely Tegan and Sara concept in that it’s less a demonstration of emotions that it’s a demonstration of thinking about emotions.

Sexual Freelancing in the Gig Economy - The New York Times - 0 views

  • We constantly use economic metaphors to describe romantic and sexual relations. Few people today refer to women as “damaged goods” or wonder why a man would “buy the cow when he can get the milk for free,” but we have “friends with benefits” and “invest in relationships.” An ex may be “on” or “off the market.” Online dating makes “shopping around” explicit. Blog after blog strategizes about how to maximize your “return on investment” on OkCupid.

  • DATING itself is a recent invention. It developed when young people began moving to cities and women began working outside private homes. By 1900, 44 percent of single American women worked. Previously, courtship had taken place under adult supervision, in private places: a parlor, a factory dance or church social. But once women started going out and earning wages, they had more freedom over where and how they met prospective mates. Because men vastly out-earned women, they typically paid for entertainment.
  • In the 1920s and ‘30s, as more and more middle-class women started going to college, parents and faculty panicked over the “rating and dating” culture, which led kids to participate in “petting parties” and take “joy rides” with members of the opposite sex.
  • By the 1950s, a new kind of dating took over: “going steady.
  • by the post-war era of full employment, this form of courtship made perfect sense. The booming economy, which was targeting the newly flush “teen” demographic, dictated that in order for everyone to partake in new consumer pleasures — for everyone to go out for a burger and root beer float on the weekends — young people had to pair off
  • The generation of Americans that came of age around the time of the 2008 financial crisis has been told constantly that we must be “flexible” and “adaptable.” Is it so surprising that we have turned into sexual freelancers? Many of us treat relationships like unpaid internships: We cannot expect them to lead to anything long-term, so we use them to get experience. If we look sharp, we might get a free lunch.
  • this kind of dating isn’t any more transactional than it was back when suitors paid women family-supervised visits or parents sought out a yenta to introduce their children at a synagogue mixer.
  • Courtship has always been dictated by changes in the market. The good news is that dating is not the same thing as love. And as anyone who has ever been in love can attest, the laws of supply and demand do not control our feelings.

  • The scientific term for this type of genetic intervention is “facilitated adaptation.”
  • De-extinction also poses a rhetorical threat to conservation biologists. The specter of extinction has been the conservation movement’s most powerful argument. What if extinction begins to be seen as a temporary inconvenience?
  • De-extinction suggests that we can technofix our way out of environmental issues generally, and that’s very, very bad.
  • How will we decide which species to resurrect?
  • Philip Seddon recently published a 10-point checklist to determine the suitability of any species for revival, taking into account causes of its extinction, possible threats it might face upon resurrection and man’s ability to destroy the species “in the event of unacceptable ecological or socioeconomic impacts.”
  • But the most visceral argument against de-extinction is animal cruelty.
  • “Is it fair to do this to these animals?” Shapiro asked. “Is ‘because we feel guilty’ a good-enough reason?” Stewart Brand made a utilitarian counterargument: “We’re going to go through some suffering, because you try a lot of times, and you get ones that don’t take. On the other hand, if you can bring bucardos back, then how many would get to live that would not have gotten to live?”
  • In “How to Permit Your Mammoth,” published in The Stanford Environmental Law Journal, Norman F. Carlin asks whether revived species should be protected by the Endangered Species Act or regulated as a genetically modified organism.
  • He concludes that revived species, “as products of human ingenuity,” should be eligible for patenting.
  • The term “de-extinction” is misleading. Passenger pigeons will not rise from the grave
  • Our understanding of the passenger pigeon’s behavior derives entirely from historical accounts.
  • There is no authoritative definition of “species.” The most widely accepted definition describes a group of organisms that can procreate with one another and produce fertile offspring, but there are many exceptions.
  • Theseus’ ship, therefore, “became a standing example among the philosophers . . . one side holding that the ship remained the same, and the other contending that it was not the same.”
  • What is coming will go well beyond the resurrection of extinct species. For millenniums, we have customized our environment, our vegetables and our animals, through breeding, fertilization and pollination. Synthetic biology offers far more sophisticated tools. The creation of novel organisms, like new animals, plants and bacteria, will transform human medicine, agriculture, energy production and much else.

Why Our Children Don't Think There Are Moral Facts - NYTimes.com - 1 views

  • I already knew that many college-aged students don’t believe in moral facts.
  • the overwhelming majority of college freshman in their classrooms view moral claims as mere opinions that are not true or are true only relative to a culture.
  • where is the view coming from?
  • ...32 more annotations...
  • the Common Core standards used by a majority of K-12 programs in the country require that students be able to “distinguish among fact, opinion, and reasoned judgment in a text.”
  • So what’s wrong with this distinction and how does it undermine the view that there are objective moral facts?
  • For example, many people once thought that the earth was flat. It’s a mistake to confuse truth (a feature of the world) with proof (a feature of our mental lives)
  • Furthermore, if proof is required for facts, then facts become person-relative. Something might be a fact for me if I can prove it but not a fact for you if you can’t. In that case, E=MC2 is a fact for a physicist but not for me.
  • worse, students are taught that claims are either facts or opinions. They are given quizzes in which they must sort claims into one camp or the other but not both. But if a fact is something that is true and an opinion is something that is believed, then many claims will obviously be both
  • How does the dichotomy between fact and opinion relate to morality
  • Kids are asked to sort facts from opinions and, without fail, every value claim is labeled as an opinion.
  • Here’s a little test devised from questions available on fact vs. opinion worksheets online: are the following facts or opinions? — Copying homework assignments is wrong. — Cursing in school is inappropriate behavior. — All men are created equal. — It is worth sacrificing some personal liberties to protect our country from terrorism. — It is wrong for people under the age of 21 to drink alcohol. — Vegetarians are healthier than people who eat meat. — Drug dealers belong in prison.
  • The answer? In each case, the worksheets categorize these claims as opinions. The explanation on offer is that each of these claims is a value claim and value claims are not facts. This is repeated ad nauseum: any claim with good, right, wrong, etc. is not a fact.
  • In summary, our public schools teach students that all claims are either facts or opinions and that all value and moral claims fall into the latter camp. The punchline: there are no moral facts. And if there are no moral facts, then there are no moral truths.
  • It should not be a surprise that there is rampant cheating on college campuses: If we’ve taught our students for 12 years that there is no fact of the matter as to whether cheating is wrong, we can’t very well blame them for doing so later on.
  • If it’s not true that it’s wrong to murder a cartoonist with whom one disagrees, then how can we be outraged? If there are no truths about what is good or valuable or right, how can we prosecute people for crimes against humanity? If it’s not true that all humans are created equal, then why vote for any political system that doesn’t benefit you over others?
  • the curriculum sets our children up for doublethink. They are told that there are no moral facts in one breath even as the next tells them how they ought to behave.
  • Our children deserve a consistent intellectual foundation. Facts are things that are true. Opinions are things we believe. Some of our beliefs are true. Others are not. Some of our beliefs are backed by evidence. Others are not.
  • Value claims are like any other claims: either true or false, evidenced or not.
  • The hard work lies not in recognizing that at least some moral claims are true but in carefully thinking through our evidence for which of the many competing moral claims is correct.
  • Moral truths are not the same as scientific truths or mathematical truths. Yet they may still be used a guiding principle for our individual lives as well as our laws.But there is equal danger of giving moral judgments the designation of truth as there is in not doing so. Many people believe that abortion is murder on the same level as shooting someone with a gun. But many others do not. So is it true that abortion is murder?Moral principles can become generally accepted and then form the basis for our laws. But many long accepted moral principles were later rejected as being faulty. "Separate but equal" is an example. Judging homosexual relationships as immoral is another example.
  • Whoa! That Einstein derived an equation is a fact. But the equation represents a theory that may have to be tweaked at some point in the future. It may be a fact that the equation foretold the violence of atomic explosions, but there are aspects of nature that elude the equation. Remember "the theory of everything?"
  • Here is a moral fact, this is a sermon masquerading as a philosophical debate on facts, opinions and truth. This professor of religion is asserting that the government via common core is teaching atheism via the opinion vs fact.He is arguing, in a dishonest form, that public schools should be teaching moral facts. Of course moral facts is code for the Ten Commandments.
  • As a fourth grade teacher, I try to teach students to read critically, including distinguishing between facts and opinions as they read (and have been doing this long before the Common Core arrived, by the way). It's not always easy for children to grasp the difference. I can only imagine the confusion that would ensue if I introduced a third category -- moral "facts" that can't be proven but are true nonetheless!
  • horrible acts occur not because of moral uncertainty, but because people are too sure that their views on morality are 100% true, and anyone who fails to recognize and submit themselves are heathens who deserve death.I can't think of any case where a society has suffered because people are too thoughtful and open-minded to different perspectives on moral truth.In any case, it's not an elementary school's job to teach "moral truths."
  • The characterization of moral anti-realism as some sort of fringe view in philosophy is misleading. Claims that can be true or false are, it seems, 'made true' by features of the world. It's not clear to many in philosophy (like me) just what features of the world could make our moral claims true. We are more likely to see people's value claims as making claims about, and enforcing conformity to, our own (contingent) social norms. This is not to hold, as Mr. McBrayer seems to think follows, that there are no reasons to endorse or criticize these social norms.
  • This is nonsense. Giving kids the tools to distinguish between fact and opinion is hard enough in an age when Republicans actively deny reality on Fox News every night. The last thing we need is to muddy their thinking with the concept of "moral facts."A fact is a belief that everyone _should_ agree upon because it is observable and testable. Morals are not agreed upon by all. Consider the hot button issue of abortion.
  • Truthfully, I'm not terribly concerned that third graders will end up taking these lessons in the definition of fact versus opinion to the extremes considered here, or take them as a license to cheat. That will come much later, when they figure out, as people always have, what they can get a way with. But Prof. McBrayer, with his blithe expectation that all the grownups know that there moral "facts"? He scares the heck out of me.
  • I've long chafed at the language of "fact" v. "opinion", which is grounded in a very particular, limited view of human cognition. In my own ethics courses, I work actively to undermine the distinction, focusing instead on considered judgment . . . or even more narrowly, on consideration itself. (See http://wp.me/p5Ag0i-6M )
  • The real waffle here is the very concept of "moral facts." Our statements of values, even very important ones are, obviously, not facts. Trying to dress them up as if they are facts, to me, argues for a pretty serious moral weakness on the part of those advancing the idea.
  • Our core values are not important because they are facts. They are important because we collectively hold them and cherish them. To lean on the false crutch of "moral facts" to admit the weakness of your own moral convictions.
  • I would like to believe that there is a core of moral facts/values upon which all humanity can agree, but it would be tough to identify exactly what those are.
  • For the the ancient philosophers, reality comprised the Good, the True, and the Beautiful (what we might now call ethics, science and art), seeing these as complementary and inseparable, though distinct, realms. With the ascendency of science in our culture as the only valid measure of reality to the detriment of ethics and art (that is, if it is not observable and provable, it is not real), we have turned the good and the beautiful into mere "social constructs" that have no validity on their own. While I am sympathetic in many ways with Dr. McBrayer's objections, I think he falls into the trap of discounting the Good and The Beautiful as valid in and of themselves, and tries, instead, to find ways to give them validity through the True. I think his argument would have been stronger had he used the language of validity rather than the language of truth. Goodness, Truth and Beauty each have their own validity, though interdependent and inseparable. When we artificially extract one of these and give it primacy, we distort reality and alienate ourselves from it.
  • Professor McBrayer seems to miss the major point of the Common Core concern: can students distinguish between premises based on (reasonably construed) fact and premises based on emotion when evaluating conclusions? I would prefer that students learn to reason rather than be taught moral 'truth' that follows Professor McBrayer's logic.
  • Moral issues cannot scientifically be treated on the level that Prof. McBrayer is attempting to use in this column: true or false, fact or opinion or both. Instead, they should be treated as important characteristics of the systematic working of a society or of a group of people in general. One can compare the working of two groups of people: one in which e.g. cheating and lying is acceptable, and one in which they are not. One can use historical or model examples to show the consequences and the working of specific systems of morals. I think that this method - suitably adjusted - can be used even in second grade.
  • Relativism has nothing to do with liberalism. The second point is that I'm not sure it does all that much harm, because I have yet to encounter a student who thought that he or she had to withhold judgment on those who hold opposing political views!

Faith in science and religion: Truth, authority, and the orderliness of nature. - 0 views

  • A common tactic of those who claim that science and religion are compatible is to argue that science, like religion, rests on faith: faith in the accuracy of what we observe, in the laws of nature, or in the value of reason
  • Such statements imply that science and religion are not that different because both seek the truth and use faith to find it
  • science is often described as a kind of religion.
  • ...14 more annotations...
  • Indeed, there is no evidence beyond revelation, authority, and scripture to support the religious claims above, and most of the world’s believers would reject at least one of them
  • faith involves pretending to know things you don’t
  • faith doesn’t mean “belief without good evidence,” but “confidence derived from scientific tests and repeated, documented experience.”
  • You have faith (i.e., confidence) that the sun will rise tomorrow because it always has, and there’s no evidence that the Earth has stopped rotating or the sun has burnt out.
  • We know no more now about the divine than we did 1,000 years ago.
  • The conflation of faith as “unevidenced belief” with faith as “justified confidence” is simply a word trick used to buttress religion.
  • The constant scrutiny of our peers ensures that science is largely self-correcting, so that we really can approach the truth about our universe
  • There is strong evidence for the Higgs boson, whose existence was confirmed last year by two independent teams using a giant accelerator and rigorous statistical analysis. But there isn’t, and never will be, any evidence for that sea of milk.
  • Two objects of scientific faith are said to be physical laws and reason. Doing science, it is said, requires unevidenced faith in the “orderliness of nature” and an “unexplained set of physical laws,” as well as in the value of reason in determining truth. Both claims are wrong.
  • The orderliness of nature—the set of so-called natural laws—is not an assumption but an observation
  • We take nature as we find it, and sometimes it behaves predictably.
  • Reason—the habit of being critical, logical, and of learning from experience—is not an a priori assumption but a tool that’s been shown to work
  • Finally, isn’t science at least based on the faith that it’s good to know the truth? Hardly.
  • So the next time you hear someone described as a “person of faith,” remember that although it’s meant as praise, it’s really an insult.

The Science of Why We Don't Believe Science | Mother Jones - 0 views

  • "A MAN WITH A CONVICTION is a hard man to change. Tell him you disagree and he turns away. Show him facts or figures and he questions your sources. Appeal to logic and he fails to see your point." So wrote the celebrated Stanford University psychologist Leon Festinger (PDF), in a passage that might have been referring to climate change denial—the persistent rejection, on the part of so many Americans today, of what we know about global warming and its human causes. But it was too early for that—this was the 1950s—and Festinger was actually describing a famous case study in psychology.
  • The theory of motivated reasoning builds on a key insight of modern neuroscience (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment.
  • In other words, when we think we're reasoning, we may instead be rationalizing. Or to use an analogy offered by University of Virginia psychologist Jonathan Haidt: We may think we're being scientists, but we're actually being lawyers (PDF). Our "reasoning" is a means to a predetermined end—winning our "case"—and is shot through with biases. They include "confirmation bias," in which we give greater heed to evidence and arguments that bolster our beliefs, and "disconfirmation bias," in which we expend disproportionate energy trying to debunk or refute views and arguments that we find uncongenial.

Thinking in a Foreign Language Makes Decisions More Rational | Wired Science | Wired.com - 2 views

  • To judge a risk more clearly, it may help to consider it in a foreign language. A series of experiments on more than 300 people from the U.S. and Korea found that thinking in a second language reduced deep-seated, misleading biases that unduly influence how risks and benefits are perceived. “Would you make the same decisions in a foreign language as you would in your native tongue?” asked psychologists led by Boaz Keysar of the University of Chicago in an April 18 Psychological Science study. “It may be intuitive that people would make the same choices regardless of the language they are using, or that the difficulty of using a foreign language would make decisions less systematic. We discovered, however, that the opposite is true: Using a foreign language reduces decision-making biases,” wrote Keysar’s team.

Clouds' Effect on Climate Change Is Last Bastion for Dissenters - NYTimes.com - 0 views

But the worst possible place to resolve such issues is the political arena." Alexander Flax, Potomac, MD Read Full Comment » Post a Comment » Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.
  • They acknowledge that the human release of greenhouse gases will cause the planet to warm. But they assert that clouds — which can either warm or cool the earth, depending on the type and location — will shift in such a way as to counter much of the expected temperature rise and preserve the equable climate on which civilization depends.
  • At gatherings of climate change skeptics on both sides of the Atlantic, Dr. Lindzen has been treated as a star. During a debate in Australia over carbon taxes, his work was cited repeatedly. When he appears at conferences of the Heartland Institute, the primary American organization pushing climate change skepticism, he is greeted by thunderous applause.
  • ...13 more annotations...
  • His idea has drawn withering criticism from other scientists, who cite errors in his papers and say proof is lacking. Enough evidence is already in hand, they say, to rule out the powerful cooling effect from clouds that would be needed to offset the increase of greenhouse gases.
  • “If you listen to the credible climate skeptics, they’ve really pushed all their chips onto clouds.”
  • Dr. Lindzen is “feeding upon an audience that wants to hear a certain message, and wants to hear it put forth by people with enough scientific reputation that it can be sustained for a while, even if it’s wrong science,” said Christopher S. Bretherton, an atmospheric researcher at the University of Washington. “I don’t think it’s intellectually honest at all.”
  • With climate policy nearly paralyzed in the United States, many other governments have also declined to take action, and worldwide emissions of greenhouse gases are soaring.
  • The most elaborate computer programs have agreed on a broad conclusion: clouds are not likely to change enough to offset the bulk of the human-caused warming. Some of the analyses predict that clouds could actually amplify the warming trend sharply through several mechanisms, including a reduction of some of the low clouds that reflect a lot of sunlight back to space. Other computer analyses foresee a largely neutral effect. The result is a big spread in forecasts of future temperature, one that scientists have not been able to narrow much in 30 years of effort.
  • The earth’s surface has already warmed about 1.4 degrees Fahrenheit since the Industrial Revolution, most of that in the last 40 years. Modest as it sounds, it is an average for the whole planet, representing an enormous addition of heat. An even larger amount is being absorbed by the oceans. The increase has caused some of the world’s land ice to melt and the oceans to rise.
  • Even in the low projection, many scientists say, the damage could be substantial. In the high projection, some polar regions could heat up by 20 or 25 degrees Fahrenheit — more than enough, over centuries or longer, to melt the Greenland ice sheet, raising sea level by a catastrophic 20 feet or more. Vast changes in  rainfall, heat waves and other weather patterns would most likely accompany such a large warming. “The big damages come if the climate sensitivity to greenhouse gases turns out to be high,” said Raymond T. Pierrehumbert, a climate scientist at the University of Chicago. “Then it’s not a bullet headed at us, but a thermonuclear warhead.”
  • But the problem of how clouds will behave in a future climate is not yet solved — making the unheralded field of cloud research one of the most important pursuits of modern science.
  • for more than a decade, Dr. Lindzen has said that when surface temperature increases, the columns of moist air rising in the tropics will rain out more of their moisture, leaving less available to be thrown off as ice, which forms the thin, high clouds known as cirrus. Just like greenhouse gases, these cirrus clouds act to reduce the cooling of the earth, and a decrease of them would counteract the increase of greenhouse gases. Dr. Lindzen calls his mechanism the iris effect, after the iris of the eye, which opens at night to let in more light. In this case, the earth’s “iris” of high clouds would be opening to let more heat escape.
  • Dr. Lindzen acknowledged that the 2009 paper contained “some stupid mistakes” in his handling of the satellite data. “It was just embarrassing,” he said in an interview. “The technical details of satellite measurements are really sort of grotesque.” Last year, he tried offering more evidence for his case, but after reviewers for a prestigious American journal criticized the paper, Dr. Lindzen published it in a little-known Korean journal. Dr. Lindzen blames groupthink among climate scientists for his publication difficulties, saying the majority is determined to suppress any dissenting views. They, in turn, contend that he routinely misrepresents the work of other researchers.
  • Ultimately, as the climate continues warming and more data accumulate, it will become obvious how clouds are reacting. But that could take decades, scientists say, and if the answer turns out to be that catastrophe looms, it would most likely be too late. By then, they say, the atmosphere would contain so much carbon dioxide as to make a substantial warming inevitable, and the gas would not return to a normal level for thousands of years.
  • In his Congressional appearances, speeches and popular writings, Dr. Lindzen offers little hint of how thin the published science supporting his position is. Instead, starting from his disputed iris mechanism, he makes what many of his colleagues see as an unwarranted leap of logic, professing near-certainty that climate change is not a problem society needs to worry about.
  • “Even if there were no political implications, it just seems deeply unprofessional and irresponsible to look at this and say, ‘We’re sure it’s not a problem,’ ” said Kerry A. Emanuel, another M.I.T. scientist. “It’s a special kind of risk, because it’s a risk to the collective civilization.”

Eric Kandel's Visions - The Chronicle Review - The Chronicle of Higher Education - 0 views

  • Judith, "barely clothed and fresh from the seduction and slaying of Holofernes, glows in her voluptuousness. Her hair is a dark sky between the golden branches of Assyrian trees, fertility symbols that represent her eroticism. This young, ecstatic, extravagantly made-up woman confronts the viewer through half-closed eyes in what appears to be a reverie of orgasmic rapture," writes Eric Kandel in his new book, The Age of Insight. Wait a minute. Writes who? Eric Kandel, the Nobel-winning neuroscientist who's spent most of his career fixated on the generously sized neurons of sea snails
  • Kandel goes on to speculate, in a bravura paragraph a few hundred pages later, on the exact neurochemical cognitive circuitry of the painting's viewer:
  • "At a base level, the aesthetics of the image's luminous gold surface, the soft rendering of the body, and the overall harmonious combination of colors could activate the pleasure circuits, triggering the release of dopamine. If Judith's smooth skin and exposed breast trigger the release of endorphins, oxytocin, and vasopressin, one might feel sexual excitement. The latent violence of Holofernes's decapitated head, as well as Judith's own sadistic gaze and upturned lip, could cause the release of norepinephrine, resulting in increased heart rate and blood pressure and triggering the fight-or-flight response. In contrast, the soft brushwork and repetitive, almost meditative, patterning may stimulate the release of serotonin. As the beholder takes in the image and its multifaceted emotional content, the release of acetylcholine to the hippocampus contributes to the storing of the image in the viewer's memory. What ultimately makes an image like Klimt's 'Judith' so irresistible and dynamic is its complexity, the way it activates a number of distinct and often conflicting emotional signals in the brain and combines them to produce a staggeringly complex and fascinating swirl of emotions."

  • His key findings on the snail, for which he shared the 2000 Nobel Prize in Physiology or Medicine, showed that learning and memory change not the neuron's basic structure but rather the nature, strength, and number of its synaptic connections. Further, through focus on the molecular biology involved in a learned reflex like Aplysia's gill retraction, Kandel demonstrated that experience alters nerve cells' synapses by changing their pattern of gene expression. In other words, learning doesn't change what neurons are, but rather what they do.
  • In Search of Memory (Norton), Kandel offered what sounded at the time like a vague research agenda for future generations in the budding field of neuroaesthetics, saying that the science of memory storage lay "at the foothills of a great mountain range." Experts grasp the "cellular and molecular mechanisms," he wrote, but need to move to the level of neural circuits to answer the question, "How are internal representations of a face, a scene, a melody, or an experience encoded in the brain?
  • Since giving a talk on the matter in 2001, he has been piecing together his own thoughts in relation to his favorite European artists
  • The field of neuroaesthetics, says one of its founders, Semir Zeki, of University College London, is just 10 to 15 years old. Through brain imaging and other studies, scholars like Zeki have explored the cognitive responses to, say, color contrasts or ambiguities of line or perspective in works by Titian, Michelangelo, Cubists, and Abstract Expressionists. Researchers have also examined the brain's pleasure centers in response to appealing landscapes.
  • it is fundamental to an understanding of human cognition and motivation. Art isn't, as Kandel paraphrases a concept from the late philosopher of art Denis Dutton, "a byproduct of evolution, but rather an evolutionary adaptation—an instinctual trait—that helps us survive because it is crucial to our well-being." The arts encode information, stories, and perspectives that allow us to appraise courses of action and the feelings and motives of others in a palatable, low-risk way.
  • "as far as activity in the brain is concerned, there is a faculty of beauty that is not dependent on the modality through which it is conveyed but which can be activated by at least two sources—musical and visual—and probably by other sources as well." Specifically, in this "brain-based theory of beauty," the paper says, that faculty is associated with activity in the medial orbitofrontal cortex.
  • It also enables Kandel—building on the work of Gombrich and the psychoanalyst and art historian Ernst Kris, among others—to compare the painters' rendering of emotion, the unconscious, and the libido with contemporaneous psychological insights from Freud about latent aggression, pleasure and death instincts, and other primal drives.
  • Kandel views the Expressionists' art through the powerful multiple lenses of turn-of-the-century Vienna's cultural mores and psychological insights. But then he refracts them further, through later discoveries in cognitive science. He seeks to reassure those who fear that the empirical and chemical will diminish the paintings' poetic power. "In art, as in science," he writes, "reductionism does not trivialize our perception—of color, light, and perspective—but allows us to see each of these components in a new way. Indeed, artists, particularly modern artists, have intentionally limited the scope and vocabulary of their expression to convey, as Mark Rothko and Ad Reinhardt do, the most essential, even spiritual ideas of their art."
  • The author of a classic textbook on neuroscience, he seems here to have written a layman's cognition textbook wrapped within a work of art history.
  • "our initial response to the most salient features of the paintings of the Austrian Modernists, like our response to a dangerous animal, is automatic. ... The answer to James's question of how an object simply perceived turns into an object emotionally felt, then, is that the portraits are never objects simply perceived. They are more like the dangerous animal at a distance—both perceived and felt."
  • If imaging is key to gauging therapeutic practices, it will be key to neuroaesthetics as well, Kandel predicts—a broad, intense array of "imaging experiments to see what happens with exaggeration, distorted faces, in the human brain and the monkey brain," viewers' responses to "mixed eroticism and aggression," and the like.
  • while the visual-perception literature might be richer at the moment, there's no reason that neuroaesthetics should restrict its emphasis to the purely visual arts at the expense of music, dance, film, and theater.
  • although Kandel considers The Age of Insight to be more a work of intellectual history than of science, the book summarizes centuries of research on perception. And so you'll find, in those hundreds of pages between Kandel's introduction to Klimt's "Judith" and the neurochemical cadenza about the viewer's response to it, dossiers on vision as information processing; the brain's three-dimensional-space mapping and its interpretations of two-dimensional renderings; face recognition; the mirror neurons that enable us to empathize and physically reflect the affect and intentions we see in others; and many related topics. Kandel elsewhere describes the scientific evidence that creativity is nurtured by spells of relaxation, which foster a connection between conscious and unconscious cognition.
  • Zeki's message to art historians, aesthetic philosophers, and others who chafe at that idea is twofold. The more diplomatic pitch is that neuroaesthetics is different, complementary, and not oppositional to other forms of arts scholarship. But "the stick," as he puts it, is that if arts scholars "want to be taken seriously" by neurobiologists, they need to take advantage of the discoveries of the past half-century. If they don't, he says, "it's a bit like the guys who said to Galileo that we'd rather not look through your telescope."
  • Matthews, a co-author of The Bard on the Brain: Understanding the Mind Through the Art of Shakespeare and the Science of Brain Imaging (Dana Press, 2003), seems open to the elucidations that science and the humanities can cast on each other. The neural pathways of our aesthetic responses are "good explanations," he says. But "does one [type of] explanation supersede all the others? I would argue that they don't, because there's a fundamental disconnection still between ... explanations of neural correlates of conscious experience and conscious experience" itself.
  • There are, Matthews says, "certain kinds of problems that are fundamentally interesting to us as a species: What is love? What motivates us to anger?" Writers put their observations on such matters into idiosyncratic stories, psychologists conceive their observations in a more formalized framework, and neuroscientists like Zeki monitor them at the level of functional changes in the brain. All of those approaches to human experience "intersect," Matthews says, "but no one of them is the explanation."
  • "Conscious experience," he says, "is something we cannot even interrogate in ourselves adequately. What we're always trying to do in effect is capture the conscious experience of the last moment. ... As we think about it, we have no way of capturing more than one part of it."
  • Kandel sees art and art history as "parent disciplines" and psychology and brain science as "antidisciplines," to be drawn together in an E.O. Wilson-like synthesis toward "consilience as an attempt to open a discussion between restricted areas of knowledge." Kandel approvingly cites Stephen Jay Gould's wish for "the sciences and humanities to become the greatest of pals ... but to keep their ineluctably different aims and logics separate as they ply their joint projects and learn from each other."

Science on the Rampage by Freeman Dyson | The New York Review of Books - 0 views

  • science is only a small part of human capability. We gain knowledge of our place in the universe not only from science but also from history, art, and literature. Science is a creative interaction of observation with imagination. “Physics at the Fringe” is what happens when imagination loses touch with observation. Imagination by itself can still enlarge our vision when observation fails. The mythologies of Carter and Velikovsky fail to be science, but they are works of art and high imagining. As William Blake told us long ago, “You never know what is enough unless you know what is more than enough.”
  • Over most of the territory of physics, theorists and experimenters are engaged in a common enterprise, and theories are tested rigorously by experiment. The theorists listen to the voice of nature speaking through experimental tools. This was true for the great theorists of the early twentieth century, Einstein and Heisenberg and Schrödinger, whose revolutionary theories of relativity and quantum mechanics were tested by precise experiments and found to fit the facts of nature. The new mathematical abstractions fit the facts, while the old mechanical models did not.
  • String cosmology is different. String cosmology is a part of theoretical physics that has become detached from experiments. String cosmologists are free to imagine universes and multiverses, guided by intuition and aesthetic judgment alone. Their creations must be logically consistent and mathematically elegant, but they are otherwise unconstrained.

  • The fringe of physics is not a sharp boundary with truth on one side and fantasy on the other. All of science is uncertain and subject to revision. The glory of science is to imagine more than we can prove. The fringe is the unexplored territory where truth and fantasy are not yet disentangled.

E.O. Wilson on altruism and the New Enlightenment - Slate Magazine - 0 views

  • we need to answer two more fundamental questions. The first is why advanced social life exists in the first place and has occurred so rarely. The second is what are the driving forces that brought it into existence.
  • Eusociality, where some individuals reduce their own reproductive potential to raise others' offspring, is what underpins the most advanced form of social organization and the dominance of social insects and humans.
  • Humans originated by multilevel selection—individual selection interacting with group selection
  • ...10 more annotations...
  • We should consider ourselves as a product of these two interacting and often competing levels of evolutionary selection. Individual versus group selection results in a mix of altruism and selfishness, of virtue and sin, among the members of a society.
  • a pretty straightforward answer as to why conflicted emotions are at the very foundation of human existence
  • why we never seem to be able to work things out satisfactorily, particularly internationally.
  • religious strife is not the consequence of differences among people. It's about
  • our tribalistic tendencies to form groups, occupy territories and react fiercely to any intrusion or threat to ourselves, our tribe and our special creation story
  • Such intense instincts could arise in evolution only by group selection—tribe competing against tribe. For me, the peculiar qualities of faith are a logical outcome of this level of biological organization.
  • I see no way out of the problems that organized religion and tribalism create other than humans just becoming more honest and fully aware of themselves. Right now we're living in what Carl Sagan correctly termed a demon-haunted world. We have created a Star Wars civilization but we have Paleolithic emotions
  • I'm devoted to the kind of environmentalism that is particularly geared towards the conservation of the living world, the rest of life on Earth, the place we came from. We need to put a lot more attention into that as something that could unify people. Surely one moral precept we can agree on is to stop destroying our birthplace, the only home humanity will ever have.
  • we ought to have another go at the Enlightenment and use that as a common goal to explain and understand ourselves, to take that self-understanding which we so sorely lack as a foundation for what we do in the moral and political realm
  • I would like to see us improving education worldwide and putting a lot more emphasis—as some Asian and European countries have—on science and technology as part of basic education

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.
  • 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.
  • 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.
  • 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.
  • 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.

Are You Smarter Than Your Grandfather? Probably Not. | Science | Smithsonian - 1 views

  • IQ test scores had significantly risen from one generation to the nex
  • widespread increase in IQ scores, and reveals some new ones, regarding teenagers’ vocabularies and the mental decline of the extremely bright in old age. Ultimately, Flynn concludes that human beings are not smarter—just more modern
  • there is a subtest called “similarities,” which asks questions like, what do dogs and rabbits have in common? Or what do truth and beauty have in common? On this subtest, the gains over those 50 years have been quite extraordinary, something like 25 points. The arithmetic subtest essentially tests arithmetical reasoning, and on that, the gains have been extremely small.

  • Formal schooling is terribly important; it helps you think in the way that IQ testers like.
  • In 1910, schools were focused on kids memorizing things about the real world. Today, they are entirely about relationships.
  • One of the fundamental things is the switch from “utilitarian spectacles” to “scientific spectacles.” The fact that we wear scientific spectacles doesn’t mean that we actually know a lot about science.
  • in 1900 in America, if you asked a child, what do dogs and rabbits have in common, they would say, “Well, you use dogs to hunt rabbits.” This is not the answer that the IQ tests want. They want you to classify. Today, a child would be likely to say, “They are both animals.” They picked up the habit of classification and use the vocabulary of science.
  • we have learned to use logic to attack the hypothetical. We have an ability to deal with a much wider range of problems than our ancestors would.
  • In 1950, teenagers could not only understand their parents, but they could also mimic their speech. Today, teenagers can still understand their parents. Their passive vocabularies are good enough. But when it comes to the words they actively use, they are much less capable of adult speak.
  • The brighter you are, the quicker after the age of 65 you have a downward curve for your analytic abilities
  • Retire from your job, but read great literature. Read about the history of science. Try and keep up your problem solving skills
  • One of the most interesting predictions is what will happen to the developing world. If they industrialize, in theory, they should have the explosive IQ gains in the coming century that we had in the last century.
