How Do We Learn Languages? | Brain Blogger - 0 views
-
human speech is a very complex process and therefore needs intensive postnatal learning to be used effectively. Furthermore, to be effective the learning phase should happen very early in life and it assumes a normally functioning hearing and brain systems.
-
Nowadays, scientists and doctors are discovering the important brain zones involved in the processing of language information. Those zones are reassembled in a number of a language networks including the Broca, the Wernicke, the middle temporal, the inferior parietal and the angular gyrus. The variety of such brain zones clearly shows that the language processing is a very complex task. On the functional level, decoding a language begins in the ear where the incoming sounds are summed in the auditory nerve as an electrical signal and delivered to the auditory cortex where neurons extract auditory objects from that signal.

The effectiveness of this process is so great that human brain is able to accurately identify words and whole phrases from a noisy background. This power of analysis brings to minds the great similarity between the brain and powerful supercomputers.
-
Until the last decade few studies compared the language acquisition in adults and children. Thanks to modern imaging and electroencephalography we are now able to address this question.
-
infants begin their lives with a very flexible brain that allows them to acquire virtually any language they are exposed to. Moreover, they can learn a language words almost equally by listening or by visual coding. This brain plasticity is the motor drive of the children capability of “cracking the speech code” of a language. With time, this ability is dramatically decreased and adults find it harder to acquire a new language.
-
clearly demonstrated that there are anatomical brain differences between fast and slow learners of foreign languages. By analyzing a group of people having a homogenous language background, scientists found that differences in specific brain regions can predict the capacity of a person to learn a second language.
-
Functional imaging of the brain revealed that activated brain parts are different between native and non-native speakers. The superior temporal gyrus is an important brain region involved in language learning. For a native speaker this part is responsible for automated processing of lexical retrieval and the build of phrase structure. In native speakers this zone is much more activated than in non-native ones.
-
Language acquisition is a long-term process by which information are stored in the brain unconsciously making them appropriate to oral and written usage. In contrast, language learning is a conscious process of knowledge acquisition that needs supervision and control by the person.

After eight years, few lines from Barack Obama’s Presidential speeches stay in mind. For all his literary and oratorical gifts, he didn’t coin the kinds of phrases that stick with repetition, as if his distaste for politics generally—the schmoozing, the fakery—extended to the fashioning of slogans. He rarely turned to figurative language, and he never stooped to “Read my lips,” or even “Ask not what your country can do for you.” His most memorable phrase, “Yes we can,” spoke to the audacious odds of his own run for the Presidency, not a clear political vision. He sought to persuade by explaining and reasoning, not by simplifying or dramatizing—a form of respect that the citizenry didn’t always deserve.
-
This aversion to rhetoric, like Obama’s aloofness from Congress, is a personal virtue that hurt him politically. It’s connected to his difficulty in sustaining public support for his program and his party. Even the President’s hero, Abraham Lincoln, was a master of the poetic sound bite.
-
This is the last week of the Obama Presidency. Historians will argue over its meaning and its merits. But, for democratic integrity, there’s no argument, no contest. Obama’s final speech wasn’t just a warning—it will stand as an emblem of what we have been and perhaps can be.

China: A Modern Babel - WSJ - 0 views

The oft-repeated claim that we must all learn Mandarin Chinese, the better to trade with our future masters, is one that readers of David Moser’s “A Billion Voices” will rapidly end up re-evaluating.
-
In fact, many Chinese don’t speak it: Even Chinese authorities quietly admit that only about 70% of the population speaks Mandarin, and merely one in 10 of those speak it fluently.
-
Mr. Moser presents a history of what is more properly called Putonghua, or “common speech,” along with a clear, concise and often amusing introduction to the limits of its spoken and written forms.

-
what Chinese schoolchildren are encouraged to think of as the longstanding natural speech of the common people is in fact an artificial hybrid, only a few decades old, although it shares a name—Mandarin—with the language of administration from imperial times. It’s a designed-by-committee camel of a language that has largely lost track of its past.
-
The idea of a national Chinese language began with the realization by the accidentally successful revolutionaries of 1911 that retaining control over a country speaking multiple languages and myriad dialects would necessitate reform. Long-term unification and the introduction of mass education would require a common language.
-
Whatever the province they originated from, the administrators of the now-toppled Great Qing Empire had all learned to communicate with one another in a second common language—Guanhua, China’s equivalent, in practical terms, of medieval Latin
-
To understand this highly compressed idiom required a considerable knowledge of the Chinese classics. Early Jesuit missionaries had labeled it Mandarin,
-
The committee decided that the four-tone dialect of the capital would be the base for a new national language but added a fifth tone whose use had lapsed in the north but not in southern dialects. The result was a language that no one actually spoke.
-
After the Communist victory of 1949, the process began all over again with fresh conferences, leading finally to the decision to use Beijing sounds, northern dialects and modern literature in the vernacular (of which there was very little) as a source of grammar.
-
This new spoken form is what is now loosely labeled Mandarin, still as alien to most Chinese as all the other Chinese languages.
-
A Latin alphabet system called Pinyin was introduced to help children learn to pronounce Chinese characters, but today it is usually abandoned after the first few years of elementary school.
-
The view that Mandarin is too difficult for mere foreigners to learn is essential to Chinese amour propre. But it is belied by the number of foreign high-school students who now learn the language by using Pinyin as a key to pronunciation —and who bask in the admiration they receive as a result.
-
Since 1949, the Chinese government, obsessed with promoting the image of a nation completely united in its love of the Communist Party, has decided that the Chinese people speak not several different languages but the same one in a variety of dialects. To say otherwise is to suggest, dangerously, that China is not one nation
-
Yet on Oct. 1, 1949, Mao Zedong announced the founding of the People’s Republic in a Hunan accent so thick that members of his audience subsequently differed about what he had said. He never mastered the Beijing sounds on which Putonghua is based, nor did Sichuanese-speaking Deng Xiaoping or most of his successors.
-
When Xi Jinping took power in 2012, many online commentators rejoiced. “At last! A Chinese leader who can speak Putonghua!” One leader down, only 400 million more common people to go.

SOPA Boycotts and the False Ideals of the Web - NYTimes.com - 1 views
-
Those rare tech companies that have come out in support of SOPA are not merely criticized but barred from industry events and subject to boycotts. We, the keepers of the flame of free speech, are banishing people for their speech. The result is a chilling atmosphere, with people afraid to speak their minds.

Our melodrama is driven by a vision of an open Internet that has already been distorted, though not by the old industries that fear piracy. For instance, until a year ago, I enjoyed a certain kind of user-generated content very much: I participated in forums in which musicians talked about musical instruments.
-
proprietary social networking — is ending my freedom to participate in the forums I used to love, at least on terms I accept. Like many other forms of contact, the musical conversations are moving into private sites, particularly Facebook. To continue to participate, I’d have to accept Facebook’s philosophy, under which it analyzes me, and is searching for new ways to charge third parties for the use of that analysis.

You might object that it’s all based on individual choice. That argument ignores the consequences of networks, and the way they function. After a certain point choice is reduced.

What if ordinary users routinely earned micropayments for their contributions? If all content were valued instead of only mogul content, perhaps an information economy would elevate success for all. But under the current terms of debate that idea can barely be whispered.
-
Once networks are established, it is hard to reduce their power. Google’s advertisers, for instance, know what will happen if they move away. The next-highest bidder for each position in Google’s auction-based model for selling ads will inherit that position if the top bidder goes elsewhere. So Google’s advertisers tend to stay put because the consequences of leaving are obvious to them
-
The obvious strategy in the fight for a piece of the advertising pie is to close off substantial parts of the Internet so Google doesn’t see it all anymore. That’s how Facebook hopes to make money, by sealing off a huge amount of user-generated information into a separate, non-Google world.
-
it’s not Facebook’s fault! We, the idealists, insisted that information be able to flow freely online, which meant that services relating to information, instead of the information itself, would be the main profit centers. Some businesses do sell content, but that doesn’t address the business side of everyday user-generated content. The adulation of “free content” inevitably meant that “advertising” would become the biggest business in the open part of the information economy
-
We in Silicon Valley undermined copyright to make commerce become more about services instead of content — more about our code instead of their files. The inevitable endgame was always that we would lose control of our own personal content, our own files.

economics forecasting policy austerity Keynes countercyclical
![](/images/link.gif)
-
These are hard times for economists. Their reputations are tarnished; their favorite doctrines are damaged. Among their most prominent thinkers, there is no consensus as to how — or whether — governments in advanced countries can improve lackluster recoveries.
-
economists at the Organization for Economic Cooperation and Development (OECD) published a retrospective study of its economic forecasts. This qualifies as an act of bureaucratic courage, because the record was predictably dismal
-
Interestingly, one item not on the list is “too much austerity.” The OECD economists found that they generally hadn’t underestimated the effects of spending cuts and tax increases intended to shrink budget deficits in Spain, Italy, Ireland, Portugal and elsewhere
- ...6 more annotations...
-
This conclusion is surely controversial because many economists attribute the weak recovery to misguided austerity, especially in Europe.
-
Perhaps history will vindicate this appeal to Keynesianism. Or perhaps not. The fact is that the United States did respond aggressively under both George W. Bush and Barack Obama. It certainly didn’t embrace austerity. Federal budgets ran massive deficits — $6.2 trillion worth from 2008 to 2013, averaging 6.4 percent of the economy (gross domestic product).Nothing like this had occurred since World War II. Yet, the economy limped along. Why wasn’t this enough?
-
It’s not just Keynesianism that’s under a cloud. The same fate has befallen monetarism — the doctrine that stable growth in the money supply can promote a more stable economy. Since 2008, the Federal Reserve has poured more than $3.2 trillion into the economy to keep interest rates low and accelerate economic growth. By monetarist reasoning, so much money pumped out so quickly should spawn higher inflation. Some economists predicted as much; it hasn’t happened yet. Consumer prices today are up a mere 1.5 percent from a year earlier.
-
The Great Recession and financial crisis changed behavior in fundamental ways that economists have yet to incorporate fully into their models or theories
-
The widespread faith that modern societies were sheltered from deep and sustained economic setbacks has been shattered, causing consumers, business managers and bankers to be more cautious in borrowing and spending. Economic stimulus may offset this caution, but if it signals that the economy is weaker than expected, it may also further depress private spending.
-
The faith in economics was, in many ways, the underlying cause of both the financial crisis and Great Recession — it made people overconfident and careless during the boom — and the basic explanation for the weak recovery, as stubborn caution displaced stubborn complacency

Joshua Foer: John Quijada and Ithkuil, the Language He Invented : The New Yorker - 2 views
-
Languages are something of a mess. They evolve over centuries through an unplanned, democratic process that leaves them teeming with irregularities, quirks, and words like “knight.” No one who set out to design a form of communication would ever end up with anything like English, Mandarin, or any of the more than six thousand languages spoken today.“Natural languages are adequate, but that doesn’t mean they’re optimal,” John Quijada, a fifty-four-year-old former employee of the California State Department of Motor Vehicles, told me. In 2004, he published a monograph on the Internet that was titled “Ithkuil: A Philosophical Design for a Hypothetical Language.” Written like a linguistics textbook, the fourteen-page Web site ran to almost a hundred and sixty thousand words. It documented the grammar, syntax, and lexicon of a language that Quijada had spent three decades inventing in his spare time. Ithkuil had never been spoken by anyone other than Quijada, and he assumed that it never would be.
-
his “greater goal” was “to attempt the creation of what human beings, left to their own devices, would never create naturally, but rather only by conscious intellectual effort: an idealized language whose aim is the highest possible degree of logic, efficiency, detail, and accuracy in cognitive expression via spoken human language, while minimizing the ambiguity, vagueness, illogic, redundancy, polysemy (multiple meanings) and overall arbitrariness that is seemingly ubiquitous in natural human language.”
-
Ithkuil, one Web site declared, “is a monument to human ingenuity and design.” It may be the most complete realization of a quixotic dream that has entranced philosophers for centuries: the creation of a more perfect language.

-
Since at least the Middle Ages, philosophers and philologists have dreamed of curing natural languages of their flaws by constructing entirely new idioms according to orderly, logical principles.
-
nventing new forms of speech is an almost cosmic urge that stems from what the linguist Marina Yaguello, the author of “Lunatic Lovers of Language,” calls “an ambivalent love-hate relationship.” Language creation is pursued by people who are so in love with what language can do that they hate what it doesn’t. “I don’t believe any other fantasy has ever been pursued with so much ardor by the human spirit, apart perhaps from the philosopher’s stone or the proof of the existence of God; or that any other utopia has caused so much ink to flow, apart perhaps from socialism,”
-
What if, they wondered, you could create a universal written language that could be understood by anyone, a set of “real characters,” just as the creation of Arabic numerals had done for counting? “This writing will be a kind of general algebra and calculus of reason, so that, instead of disputing, we can say that ‘we calculate,’ ” Leibniz wrote, in 1679.
-
In his “Essay Towards a Real Character, and a Philosophical Language,” from 1668, Wilkins laid out a sprawling taxonomic tree that was intended to represent a rational classification of every concept, thing, and action in the universe. Each branch along the tree corresponded to a letter or a syllable, so that assembling a word was simply a matter of tracing a set of forking limbs
-
Solresol, the creation of a French musician named Jean-François Sudre, was among the first of these universal languages to gain popular attention. It had only seven syllables: Do, Re, Mi, Fa, So, La, and Si. Words could be sung, or performed on a violin. Or, since the language could also be translated into the seven colors of the rainbow, sentences could be woven into a textile as a stream of colors.
-
“I had this realization that every individual language does at least one thing better than every other language,” he said. For example, the Australian Aboriginal language Guugu Yimithirr doesn’t use egocentric coördinates like “left,” “right,” “in front of,” or “behind.” Instead, speakers use only the cardinal directions. They don’t have left and right legs but north and south legs, which become east and west legs upon turning ninety degrees
-
Among the Wakashan Indians of the Pacific Northwest, a grammatically correct sentence can’t be formed without providing what linguists refer to as “evidentiality,” inflecting the verb to indicate whether you are speaking from direct experience, inference, conjecture, or hearsay.
-
Quijada began wondering, “What if there were one single language that combined the coolest features from all the world’s languages?”
-
he started scribbling notes on an entirely new grammar that would eventually incorporate not only Wakashan evidentiality and Guugu Yimithirr coördinates but also Niger-Kordofanian aspectual systems, the nominal cases of Basque, the fourth-person referent found in several nearly extinct Native American languages, and a dozen other wild ways of forming sentences.
-
he discovered “Metaphors We Live By,” a seminal book, published in 1980, by the cognitive linguists George Lakoff and Mark Johnson, which argues that the way we think is structured by conceptual systems that are largely metaphorical in nature. Life is a journey. Time is money. Argument is war. For better or worse, these figures of speech are profoundly embedded in how we think.
-
I asked him if he could come up with an entirely new concept on the spot, one for which there was no word in any existing language. He thought about it for a moment. “Well, no language, as far as I know, has a single word for that chin-stroking moment you get, often accompanied by a frown on your face, when someone expresses an idea that you’ve never thought of and you have a moment of suddenly seeing possibilities you never saw before.” He paused, as if leafing through a mental dictionary. “In Ithkuil, it’s ašţal.”
-
Many conlanging projects begin with a simple premise that violates the inherited conventions of linguistics in some new way. Aeo uses only vowels. Kēlen has no verbs. Toki Pona, a language inspired by Taoist ideals, was designed to test how simple a language could be. It has just a hundred and twenty-three words and fourteen basic sound units. Brithenig is an answer to the question of what English might have sounded like as a Romance language, if vulgar Latin had taken root on the British Isles. Láadan, a feminist language developed in the early nineteen-eighties, includes words like radíidin, defined as a “non-holiday, a time allegedly a holiday but actually so much a burden because of work and preparations that it is a dreaded occasion; especially when there are too many guests and none of them help.”
-
most conlangers come to their craft by way of fantasy and science fiction. J. R. R. Tolkien, who called conlanging his “secret vice,” maintained that he created the “Lord of the Rings” trilogy for the primary purpose of giving his invented languages, Quenya, Sindarin, and Khuzdul, a universe in which they could be spoken. And arguably the most commercially successful invented language of all time is Klingon, which has its own translation of “Hamlet” and a dictionary that has sold more than three hundred thousand copies.
-
He imagined that Ithkuil might be able to do what Lakoff and Johnson said natural languages could not: force its speakers to precisely identify what they mean to say. No hemming, no hawing, no hiding true meaning behind jargon and metaphor. By requiring speakers to carefully consider the meaning of their words, he hoped that his analytical language would force many of the subterranean quirks of human cognition to the surface, and free people from the bugs that infect their thinking.
-
Brown based the grammar for his ten-thousand-word language, called Loglan, on the rules of formal predicate logic used by analytical philosophers. He hoped that, by training research subjects to speak Loglan, he might turn them into more logical thinkers. If we could change how we think by changing how we speak, then the radical possibility existed of creating a new human condition.
-
today the stronger versions of the Sapir-Whorf hypothesis have “sunk into . . . disrepute among respectable linguists,” as Guy Deutscher writes, in “Through the Looking Glass: Why the World Looks Different in Other Languages.” But, as Deutscher points out, there is evidence to support the less radical assertion that the particular language we speak influences how we perceive the world. For example, speakers of gendered languages, like Spanish, in which all nouns are either masculine or feminine, actually seem to think about objects differently depending on whether the language treats them as masculine or feminine
-
The final version of Ithkuil, which Quijada published in 2011, has twenty-two grammatical categories for verbs, compared with the six—tense, aspect, person, number, mood, and voice—that exist in English. Eighteen hundred distinct suffixes further refine a speaker’s intent. Through a process of laborious conjugation that would befuddle even the most competent Latin grammarian, Ithkuil requires a speaker to home in on the exact idea he means to express, and attempts to remove any possibility for vagueness.
-
Every language has its own phonemic inventory, or library of sounds, from which a speaker can string together words. Consonant-poor Hawaiian has just thirteen phonemes. English has around forty-two, depending on dialect. In order to pack as much meaning as possible into each word, Ithkuil has fifty-eight phonemes. The original version of the language included a repertoire of grunts, wheezes, and hacks that are borrowed from some of the world’s most obscure tongues. One particular hard-to-make clicklike sound, a voiceless uvular ejective affricate, has been found in only a few other languages, including the Caucasian language Ubykh, whose last native speaker died in 1992.
-
Human interactions are governed by a set of implicit codes that can sometimes seem frustratingly opaque, and whose misreading can quickly put you on the outside looking in. Irony, metaphor, ambiguity: these are the ingenious instruments that allow us to mean more than we say. But in Ithkuil ambiguity is quashed in the interest of making all that is implicit explicit. An ironic statement is tagged with the verbal affix ’kçç. Hyperbolic statements are inflected by the letter ’m.
-
“I wanted to use Ithkuil to show how you would discuss philosophy and emotional states transparently,” Quijada said. To attempt to translate a thought into Ithkuil requires investigating a spectrum of subtle variations in meaning that are not recorded in any natural language. You cannot express a thought without first considering all the neighboring thoughts that it is not. Though words in Ithkuil may sound like a hacking cough, they have an inherent and unavoidable depth. “It’s the ideal language for political and philosophical debate—any forum where people hide their intent or obfuscate behind language,” Quijada co
-
In Ithkuil, the difference between glimpsing, glancing, and gawking is the mere flick of a vowel. Each of these distinctions is expressed simply as a conjugation of the root word for vision. Hunched over the dining-room table, Quijada showed me how he would translate “gawk” into Ithkuil. First, though, since words in Ithkuil are assembled from individual atoms of meaning, he had to engage in some introspection about what exactly he meant to say.For fifteen minutes, he flipped backward and forward through his thick spiral-bound manuscript, scratching his head, pondering each of the word’s aspects, as he packed the verb with all of gawking’s many connotations. As he assembled the evolving word from its constituent meanings, he scribbled its pieces on a notepad. He added the “second degree of the affix for expectation of outcome” to suggest an element of surprise that is more than mere unpreparedness but less than outright shock, and the “third degree of the affix for contextual appropriateness” to suggest an element of impropriety that is less than scandalous but more than simply eyebrow-raising. As he rapped his pen against the notepad, he paged through his manuscript in search of the third pattern of the first stem of the root for “shock” to suggest a “non-volitional physiological response,” and then, after several moments of contemplation, he decided that gawking required the use of the “resultative format” to suggest “an event which occurs in conjunction with the conflated sense but is also caused by it.” He eventually emerged with a tiny word that hardly rolled off the tongue: apq’uxasiu. He spoke the first clacking syllable aloud a couple of times before deciding that he had the pronunciation right, and then wrote it down in the script he had invented for printed Ithkuil:
-
“You can make up words by the millions to describe concepts that have never existed in any language before,” he said.
-
Neither Sapir nor Whorf formulated a definitive version of the hypothesis that bears their names, but in general the theory argues that the language we speak actually shapes our experience of reality. Speakers of different languages think differently. Stronger versions of the hypothesis go even further than this, to suggest that language constrains the set of possible thoughts that we can have. In 1955, a sociologist and science-fiction writer named James Cooke Brown decided he would test the Sapir-Whorf hypothesis by creating a “culturally neutral” “model language” that might recondition its speakers’ brains.
-
“We think that when a person learns Ithkuil his brain works faster,” Vishneva told him, in Russian. She spoke through a translator, as neither she nor Quijada was yet fluent in their shared language. “With Ithkuil, you always have to be reflecting on yourself. Using Ithkuil, we can see things that exist but don’t have names, in the same way that Mendeleyev’s periodic table showed gaps where we knew elements should be that had yet to be discovered.”
-
Lakoff, who is seventy-one, bearded, and, like Quijada, broadly built, seemed to have read a fair portion of the Ithkuil manuscript and familiarized himself with the language’s nuances.“There are a whole lot of questions I have about this,” he told Quijada, and then explained how he felt Quijada had misread his work on metaphor. “Metaphors don’t just show up in language,” he said. “The metaphor isn’t in the word, it’s in the idea,” and it can’t be wished away with grammar.“For me, as a linguist looking at this, I have to say, ‘O.K., this isn’t going to be used.’ It has an assumption of efficiency that really isn’t efficient, given how the brain works. It misses the metaphor stuff. But the parts that are successful are really nontrivial. This may be an impossible language,” he said. “But if you think of it as a conceptual-art project I think it’s fascinating.”

We speak so effortlessly that most of us never think about it. But psychologists and neuroscientists are captivated by the human capacity to communicate with language.

Untangling the brain’s mechanisms for language has been a pillar of neuroscience since its inception. New research published in the Proceedings for the National Academy of Sciences about the different connections going on in the brains of Mandarin and English speakers, demonstrates just how flexible our ability to learn language really is.

six to ten months children have already learned to be sensitive to the basic sounds, known as phonemes, that matter in their native language.
-
language requires real-time mappings between words and their meanings. This requires that the sounds heard in speech – decoded in the auditory cortex – must be integrated with knowledge about what they mean – in the frontal cortex.
-
Modern theories on connectionism – the idea that knowledge is distributed across different parts of the brain and not tucked into dedicated modules like Broca’s area – have compelled researchers to take a closer look.
-
Mandarin Chinese is a tonal language in which the same basic sounds can refer to vastly different things based on the tone with which it is spoken
-
non-tonal language such as English, tone might convey emotional information about the speaker, but indicates nothing about the meaning of the word that is spoken
-
found that these differences between Mandarin Chinese and English change the way the brain’s networks work.
-
researchers took advantage of the basic differences between Mandarin Chinese and English to investigate the differences between the language networks of native speakers of tonal and non-tonal languages. Thirty native Chinese speakers were matched on age, gender, and handedness (they were all right-handed) with a sample of native English speakers. All participants listened to intelligible and unintelligible speech and were asked to judge the gender of the speaker.
-
English speakers showed stronger connectivity leading from Wernicke’s area to Broca’s area. This increased connectivity was attributed to English relying more heavily on phonological information, or sounds rather than tones.
-
Chinese speakers had stronger connections leading from an area of the brain called the anterior superior temporal gyrus – which has been identified as a “semantic hub” critical in supporting language – to both Broca’s and Wernicke’s area.
-
increased connectivity is attributed to the enhanced mapping of sound and meaning going on in people who speak tonal languages.
-
second difference showed activation in an area of the brain’s right hemisphere, but only among the Chinese speakers
-
findings emphasise the importance of developing a bilateral network between the two brain hemispheres to speak and understand languages, particularly for tonal languages like Mandarin Chinese.

“Generally speaking, a people’s metaphors and figures of speech will come out of their basic economy,” Knight continues: If somebody lives near the ocean and they fish, their language will be full of those metaphors. If people are farmers, they will use that kind of figure of speech. Metaphors are alive. When they come into being, they are informed by the politics and the sociology and the economy of now. That’s how language is.

Where are we humans going, as a species? If science fiction is any guide, we will genetically evolve like in X-Men, become genetically engineered as in Gattaca, or become cybernetically enhanced like General Grievous in Star Wars.
-
There is, however, another avenue for human evolution, one mostly unappreciated in both science and fiction. It is this unheralded mechanism that will usher in the next stage of human, giving future people exquisite powers we do not currently possess, powers worthy of natural selection itself. And, importantly, it doesn’t require us to transform into cyborgs or bio-engineered lab rats. It merely relies on our natural bodies and brains functioning as they have for millions of years. This mystery mechanism of human transformation is neuronal recycling, coined by neuroscientist Stanislas Dehaene, wherein the brain’s innate capabilities are harnessed for altogether novel functions.
-
The root of these misconceptions is the radical underappreciation of the design engineered by natural selection into the powers implemented by our bodies and brains, something central to my 2009 book, The Vision Revolution. For example, optical illusions (such as the Hering) are not examples of the brain’s poor hardware design, but, rather, consequences of intricate evolutionary software for generating perceptions that correct for neural latencies in normal circumstances.

Like all animal brains, human brains are not general-purpose universal learning machines, but, instead, are intricately structured suites of instincts optimized for the environments in which they evolved. To harness our brains, we want to let the brain’s brilliant mechanisms run as intended—i.e., not to be twisted. Rather, the strategy is to twist Y into a shape that the brain does know how to process.
-
there is a very good reason to be optimistic that the next stage of human will come via the form of adaptive harnessing, rather than direct technological enhancement: It has already happened. We have already been transformed via harnessing beyond what we once were. We’re already Human 2.0, not the Human 1.0, or Homo sapiens, that natural selection made us. We Human 2.0’s have, among many powers, three that are central to who we take ourselves to be today: writing, speech, and music (the latter perhaps being the pinnacle of the arts). Yet these three capabilities, despite having all the hallmarks of design, were not a result of natural selection, nor were they the result of genetic engineering or cybernetic enhancement to our brains. Instead, and as I argue in both The Vision Revolution and my forthcoming Harnessed, these are powers we acquired by virtue of harnessing, or neuronal recycling.
-
Although the step from Human 1.0 to 2.0 was via cultural selection, not via explicit human designers, does the transformation to Human 3.0 need to be entirely due to a process like cultural evolution, or might we have any hope of purposely guiding our transformation? When considering our future, that’s probably the most relevant question we should be asking ourselves.
-
One of my reasons for optimism is that nature-harnessing technologies (like writing, speech, and music) must mimic fundamental ecological features in nature, and that is a much easier task for scientists to tackle than emulating the exhorbitantly complex mechanisms of the brain

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,

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.

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,"

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."

the idea of recurring historic episodes has a powerful effect on decision-making in the here and now. Disagreements over policy often come down to the search for the right historic pattern to apply.

the idea that Europe on the eve of the Holocaust is the most useful guide to the world in 2015 runs through arguments about Iran policy. And if that is the correct model to apply, the right "picture in our heads" as Walter Lippmann put it in Public Opinion, then these conclusions naturally follow:

• The threatening power of the time—Nazi Germany then, the Islamists' Iran now—is a force of unalloyed evil whose very existence threatens decent life everywhere.
-
• That emerging power cannot be reasoned or bargained with but must ultimately be stopped and broken
-
• The appeasers' blindness endangers people all around the world but poses an especially intolerable threat to Jews
-
• As a result of all these factors, no deal with such an implacable enemy is preferable to an inevitably flawed and Munich-like false-hope deal.

Also, and crucially, it means that the most obvious criticism of the speech—what's Netanyahu's plan for getting Iran to agree?—is irrelevant. What was the Allies' "plan" for getting Hitler to agree? The plan was to destroy his regime.

If, on the other hand, you think that the contrasts with 1938 are more striking than the similarities, you see things differently. As a brief reminder of the contrasts: the Germany of 1938 was much richer and more powerful than the Iran of today. Germany was rapidly expansionist; Iran, despite its terrorist work through proxies, has not been. The Nazi leaders had engulfed the world in war less than a decade after taking power. Iran's leaders, oppressive and destructive, have not shown similar suicidal recklessness. European Jews of 1938 were stateless, unarmed, and vulnerable. Modern Israel is a powerful, nuclear-armed force. Moreover, the world after the first wartime use of nuclear weapons, of course by the United States, is different from the world before that point.

Here's what I understand the more clearly after these past few weeks' drama over Prime Minister Netanyahu's speech. These differences in historic model are deep and powerful, and people with one model in mind are not going to convince people with the other mental picture.

The alarming headlines came quickly Wednesday morning: “Now It’s Getting Serious: 2017 Could See a Bacon Shortage.”

To create a panic “was not our intent,” Mr. Deaton added with a laugh. “We can’t control how the news is interpreted.”

With the development of Internet and social media, we find the news on the website, paper, TV more unreliable. Partly because we can easily find alternate statement that points out the flaws, but mostly, it's because the news today likes to use exaggeration to grab the attention of the general population. Media should realize the impact and panic it can cause in the society before they report news. Although freedom of speech is appreciated, that doesn't mean the media can put aside its responsibility to guide the general population in a good direction. I remember there was a fake news after the big earthquake in Japan saying that salt can prevent nuclear radiation, then people were all panic and bought salt. It was very funny that in some places, some people were even fighting for a pack of salt. The media should make sure that people won't misunderstand the message before they publish. --Sissi (2/1/2017)

And former President Barack Obama said at an off-the-record conference at the Massachusetts Institute of Technology last month that he worried Americans were living in “entirely different realities” and that large tech companies like Facebook were “not just an invisible platform, they’re shaping our culture in powerful ways.” The contents of the speech were published by Reason magazine.

The panelists accused social media platforms of delisting their videos or stripping them of advertising. Such charges have long been staples of far-right online discourse, especially among YouTubers, but Mr. Schweizer’s project is poised to bring such arguments to a new — and potentially larger — audience.

It remains to be seen how effective Google’s new policy on fake news will be in practice. The policy will rely on a combination of automated and human reviews to help determine what is fake. Although satire sites like The Onion are not the target of the policy, it is not clear whether some of them, which often run fake news stories written for humorous effect, will be inadvertently affected by Google’s change.

Company start to pay attention to the fake news on the social media. It reminded me of the government involvement in economics. Although internet should be a place free of speech, there are mounting amount of fake news and alternative facts now that the company need to regulate and make rules to restrict it. I think as long as there is human society, we need rule. In free markets, we also need government regulation to remain a balance. --Sissi (3/6/2017)
