The crash, which killed all 49 people on board as well as one person on the ground, should never have happened.

aptain’s response to the stall warning, the investigators reported, “should have been automatic, but his improper flight control inputs were inconsistent with his training” and instead revealed “startle and confusion.

Automation has become so sophisticated that on a typical passenger flight, a human pilot holds the controls for a grand total of just three minutes.

We humans have been handing off chores, both physical and mental, to tools since the invention of the lever, the wheel, and the counting bead.

And that, many aviation and automation experts have concluded, is a problem. Overuse of automation erodes pilots’ expertise and dulls their reflexes,

No one doubts that autopilot has contributed to improvements in flight safety over the years. It reduces pilot fatigue and provides advance warnings of problems, and it can keep a plane airborne should the crew become disabled. But the steady overall decline in plane crashes masks the recent arrival of “a spectacularly new type of accident,”

“We’re forgetting how to fly.”

The experience of airlines should give us pause. It reveals that automation, for all its benefits, can take a toll on the performance and talents of those who rely on it. The implications go well beyond safety. Because automation alters how we act, how we learn, and what we know, it has an ethical dimension. The choices we make, or fail to make, about which tasks we hand off to machines shape our lives and the place we make for ourselves in the world.

What pilots spend a lot of time doing is monitoring screens and keying in data. They’ve become, it’s not much of an exaggeration to say, computer operators.

Examples of complacency and bias have been well documented in high-risk situations—on flight decks and battlefields, in factory control rooms—but recent studies suggest that the problems can bedevil anyone working with a computer

That may leave the person operating the computer to play the role of a high-tech clerk—entering data, monitoring outputs, and watching for failures. Rather than opening new frontiers of thought and action, software ends up narrowing our focus.

A labor-saving device doesn’t just provide a substitute for some isolated component of a job or other activity. It alters the character of the entire task, including the roles, attitudes, and skills of the people taking part.

when we work with computers, we often fall victim to two cognitive ailments—complacency and bias—that can undercut our performance and lead to mistakes. Automation complacency occurs when a computer lulls us into a false sense of security. Confident that the machine will work flawlessly and handle any problem that crops up, we allow our attention to drift.

Automation bias occurs when we place too much faith in the accuracy of the information coming through our monitors. Our trust in the software becomes so strong that we ignore or discount other information sources, including our own eyes and ears

Automation is different now. Computers can be programmed to perform complex activities in which a succession of tightly coordinated tasks is carried out through an evaluation of many variables. Many software programs take on intellectual work—observing and sensing, analyzing and judging, even making decisions—that until recently was considered the preserve of humans.

Automation turns us from actors into observers. Instead of manipulating the yoke, we watch the screen. That shift may make our lives easier, but it can also inhibit the development of expertise.

Since the late 1970s, psychologists have been documenting a phenomenon called the “generation effect.” It was first observed in studies of vocabulary, which revealed that people remember words much better when they actively call them to mind—when they generate them—than when they simply read them.

When you engage actively in a task, you set off intricate mental processes that allow you to retain more knowledge. You learn more and remember more. When you repeat the same task over a long period, your brain constructs specialized neural circuits dedicated to the activit

What looks like instinct is hard-won skill, skill that requires exactly the kind of struggle that modern software seeks to alleviate.

In many businesses, managers and other professionals have come to depend on decision-support systems to analyze information and suggest courses of action. Accountants, for example, use the systems in corporate audits. The applications speed the work, but some signs suggest that as the software becomes more capable, the accountants become less so.

You can put limits on the scope of automation, making sure that people working with computers perform challenging tasks rather than merely observing.

Experts used to assume that there were limits to the ability of programmers to automate complicated tasks, particularly those involving sensory perception, pattern recognition, and conceptual knowledge

Who needs humans, anyway? That question, in one rhetorical form or another, comes up frequently in discussions of automation. If computers’ abilities are expanding so quickly and if people, by comparison, seem slow, clumsy, and error-prone, why not build immaculately self-contained systems that perform flawlessly without any human oversight or intervention? Why not take the human factor out of the equation?

The cure for imperfect automation is total automation.

That idea is seductive, but no machine is infallible. Sooner or later, even the most advanced technology will break down, misfire, or, in the case of a computerized system, encounter circumstances that its designers never anticipated. As automation technologies become more complex, relying on interdependencies among algorithms, databases, sensors, and mechanical parts, the potential sources of failure multiply. They also become harder to detect.

conundrum of computer automation.

Because many system designers assume that human operators are “unreliable and inefficient,” at least when compared with a computer, they strive to give the operators as small a role as possible.

People end up functioning as mere monitors, passive watchers of screens. That’s a job that humans, with our notoriously wandering minds, are especially bad at

people have trouble maintaining their attention on a stable display of information for more than half an hour. “This means,” Bainbridge observed, “that it is humanly impossible to carry out the basic function of monitoring for unlikely abnormalities.”

a person’s skills “deteriorate when they are not used,” even an experienced operator will eventually begin to act like an inexperienced one if restricted to just watching.

You can program software to shift control back to human operators at frequent but irregular intervals; knowing that they may need to take command at any moment keeps people engaged, promoting situational awareness and learning.

What’s most astonishing, and unsettling, about computer automation is that it’s still in its early stages.

most software applications don’t foster learning and engagement. In fact, they have the opposite effect. That’s because taking the steps necessary to promote the development and maintenance of expertise almost always entails a sacrifice of speed and productivity.

Learning requires inefficiency. Businesses, which seek to maximize productivity and profit, would rarely accept such a trade-off. Individuals, too, almost always seek efficiency and convenience.

Abstract concerns about the fate of human talent can’t compete with the allure of saving time and money.

The small island of Igloolik, off the coast of the Melville Peninsula in the Nunavut territory of northern Canada, is a bewildering place in the winter.

, Inuit hunters have for some 4,000 years ventured out from their homes on the island and traveled across miles of ice and tundra to search for game. The hunters’ ability to navigate vast stretches of the barren Arctic terrain, where landmarks are few, snow formations are in constant flux, and trails disappear overnight, has amazed explorers and scientists for centuries. The Inuit’s extraordinary way-finding skills are born not of technological prowess—they long eschewed maps and compasses—but of a profound understanding of winds, snowdrift patterns, animal behavior, stars, and tides.

The Igloolik hunters have begun to rely on computer-generated maps to get around. Adoption of GPS technology has been particularly strong among younger Inuit, and it’s not hard to understand why.

But as GPS devices have proliferated on Igloolik, reports of serious accidents during hunts have spread. A hunter who hasn’t developed way-finding skills can easily become lost, particularly if his GPS receiver fails.

The routes so meticulously plotted on satellite maps can also give hunters tunnel vision, leading them onto thin ice or into other hazards a skilled navigator would avoid.

An Inuit on a GPS-equipped snowmobile is not so different from a suburban commuter in a GPS-equipped SUV: as he devotes his attention to the instructions coming from the computer, he loses sight of his surroundings. He travels “blindfolded,” as Aporta puts it

A unique talent that has distinguished a people for centuries may evaporate in a generation.

Computer automation severs the ends from the means. It makes getting what we want easier, but it distances us from the work of knowing. As we transform ourselves into creatures of the screen, we face an existential question: Does our essence still lie in what we know, or are we now content to be defined by what we want?

It worked in the art world, but it hasn’t hit the fossil world.”

The mating and cohabitation produced the exact same effects [as TSA],” said Bruce Cushing, a behavioral neuroscientist at the University of Akron who was not involved in the study. “That is really powerful.”

The system is small: about 1-2% the mass of the Milky Way and is rich in heavier elements.

astronomers are likely to discover even more distant galaxies when Nasa's James Webb Space Telescope (JWST) is launched and other ground-based telescopes come online.

One very interesting way to learn about the Universe is to study these outliers and that tells us something about what sort of physical processes are dominating galaxy formation and galaxy evolution. "What was great about this galaxy is not only is it so distant, it is also pretty exceptional."

But it has a surprising feature: it is turning gas and dust into new stars at a remarkable rate, churning them out hundreds of times faster than our own galaxy can.

This is an important step forward, but we need to continue looking for more.

It is not that the English language has ceased to be a precious possession; on the contrary, it is far more important now than it ever was in my childhood. But its importance has little or nothing to do any longer with the dream of rootedness. English is the premier international language, the global medium of communication and exchange.

This does not mean that I should abandon the paper assignment; it is an important form of training for a range of very different challenges that lie in their future. But I see that their deep imaginative engagement with Shakespeare, their intoxication, lies elsewhere.

When I ask them to write a 10-page paper analyzing a particular web of metaphors, exploring a complex theme or amassing evidence to support an argument, the results are often wooden; when I ask them to analyze a film clip, perform a scene or make a video, I stand a better chance of receiving something extraordinary.

as I have discovered in my teaching, it is a different Shakespeare from the one with whom I first fell in love. Many of my students may have less verbal acuity than in years past, but they often possess highly developed visual, musical and performative skills. They intuitively grasp, in a way I came to understand only slowly, the pervasiveness of songs in Shakespeare’s plays, the strange ways that his scenes flow one into another or the cunning alternation of close-ups and long views

The M.I.T. Global Shakespeare Project features an electronic archive that includes images of every page of the First Folio of 1623. In the Norton Shakespeare, which I edit, the texts of his plays are now available not only in the massive printed book with which I was initiated but also on a digital platform. One click and you can hear each song as it might have sounded on the Elizabethan stage; another click and you listen to key scenes read by a troupe of professional actors. It is a kind of magic unimagined even a few years ago or rather imaginable only as the book of a wizard like Prospero in ‘‘The Tempest.’

But it is not the new technology alone that attracts students to Shakespeare; it is still more his presence throughout the world as the common currency of humanity. In Taiwan, Tokyo and Nanjing, in a verdant corner of the Villa Borghese gardens in Rome and in an ancient garden in Kabul, in Berlin and Bangkok and Bangalore, his plays continue to find new and unexpected ways to enchant.

In the structured course, all demographic groups reported completing the readings more frequently and spending more time studying; all groups also achieved higher final grades than did students in the lecture course.

Other active-learning courses administer frequent quizzes that oblige students to retrieve knowledge from memory rather than passively read it over in a textbook. Such quizzes have been shown to improve retention of factual material among all kinds of students.

The act of putting one’s own thoughts into words and communicating them to others, research has shown, is a powerful contributor to learning. Active-learning courses regularly provide opportunities for students to talk and debate with one another in a collaborative, low-pressure environment.

researchers from the University of Massachusetts Amherst and Yale University compare a course in physical chemistry taught in traditional lecture style to the same course taught in a “flipped” format, in which lectures were moved online and more time was devoted to in-class problem-solving activities. Exam performance over all was nearly 12 percent higher in the flipped class

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.”

Instead of leading to a search for certainty, as Descartes’s dream did, Zhuangzi came to the realization that he had perceived “the transformation of things,” indicating that one should go along with this transformation rather than trying in vain to search for what is real.

It even expands epistemology into the non-conceptual realm in which the accessibility of knowledge is dependent on the cultivation of cognitive abilities, and not simply on whatever is “publicly observable” to everyone. It also shows that cultivation of the person is not confined to “knowing how.” An exemplary person may well have the great charisma to affect others but does not necessarily know how to affect others.

The Buddhist doctrine of no-self surely looks metaphysical, but its real aim is to free one from suffering, since according to Buddhism suffering comes ultimately from attachment to the self. Buddhist meditations are kung fu practices to shake off one’s attachment, and not just intellectual inquiries for getting propositional truth.

The essence of kung fu — various arts and instructions about how to cultivate the person and conduct one’s life — is often hard to digest for those who are used to the flavor and texture of mainstream Western philosophy. It is understandable that, even after sincere willingness to try, one is often still turned away by the lack of clear definitions of key terms and the absence of linear arguments in classic Chinese texts. This, however, is not a weakness, but rather a requirement of the kung fu orientation — not unlike the way that learning how to swim requires one to focus on practice and not on conceptual understanding.

the views of Mencius and his later opponent Xunzi’s views about human nature are more recommendations of how one should view oneself in order to become a better person than metaphysical assertions about whether humans are by nature good or bad. Though each man’s assertions about human nature are incompatible with each other, they may still function inside the Confucian tradition as alternative ways of cultivation.

Western philosophy at its origin is similar to classic Chinese philosophy. The significance of this point is not merely in revealing historical facts. It calls our attention to a dimension that has been eclipsed by the obsession with the search for eternal, universal truth and the way it is practiced, namely through rational arguments.

One might well consider the Chinese kung fu perspective a form of pragmatism.  The proximity between the two is probably why the latter was well received in China early last century when John Dewey toured the country. What the kung fu perspective adds to the pragmatic approach, however, is its clear emphasis on the cultivation and transformation of the person, a dimension that is already in Dewey and William James but that often gets neglected

A kung fu master does not simply make good choices and use effective instruments to satisfy whatever preferences a person happens to have. In fact the subject is never simply accepted as a given. While an efficacious action may be the result of a sound rational decision, a good action that demonstrates kung fu has to be rooted in the entire person, including one’s bodily dispositions and sentiments, and its goodness is displayed not only through its consequences but also in the artistic style one does it. It also brings forward what Charles Taylor calls the “background” — elements such as tradition and community — in our understanding of the formation of a person’s beliefs and attitudes. Through the kung fu approach, classic Chinese philosophy displays a holistic vision that brings together these marginalized dimensions and thereby forces one to pay close attention to the ways they affect each other.

This kung fu approach shares a lot of insights with the Aristotelian virtue ethics, which focuses on the cultivation of the agent instead of on the formulation of rules of conduct. Yet unlike Aristotelian ethics, the kung fu approach to ethics does not rely on any metaphysics for justification.

This approach opens up the possibility of allowing multiple competing visions of excellence, including the metaphysics or religious beliefs by which they are understood and guided, and justification of these beliefs is then left to the concrete human experiences.

it is more appropriate to consider kung fu as a form of art. Art is not ultimately measured by its dominance of the market. In addition, the function of art is not accurate reflection of the real world; its expression is not constrained to the form of universal principles and logical reasoning, and it requires cultivation of the artist, embodiment of virtues/virtuosities, and imagination and creativity.

If philosophy is “a way of life,” as Pierre Hadot puts it, the kung fu approach suggests that we take philosophy as the pursuit of the art of living well, and not just as a narrowly defined rational way of life.

let him develop the habit of smiling any time he starts feeling rotten. Believe it or not, it works.

Of all philosophical writers on metaphor, Nietzsche probably draws the strongest conclusions from this situation. ''Tropes,'' he writes, ''are not something that can be added or abstracted from language at will—they are its truest nature.'' He argues that there is ''no real knowing apart from metaphor,'' by which he means that we experience reality through metaphors, and our notion of literal meaning simply reflects the ossification of language, as figures of speech lose their vitality. He emphasizes in The Genealogy of Morals how metaphor tends to extend its sway, to bring wider ranges of experience under its wing. He goes so far as to say that ''the drive toward the formation of metaphor is the fundamental human drive.'' For him, literal and figurative meaning are not stable categories, but historical ones determined by their social context.

the evolution of abstractions is always a case of going from the physical and sensible to the abstract.

, the rodent displayed a heightened fear response, although no foot shock had ever been given in that location. The mice eventually became conditioned to the false memory, and would freeze in Box A even in the absence of pulsing light.

“The brain mechanisms for forming and recalling the false memories are not distinguishable from those underlying genuine memories,” said Tonegawa.

hypothesized that a similar mechanism could be behind the formation of false memories in humans and said the findings underscore the problematic nature of eyewitness testimony in court proceedings.

“We hope this kind of research will reinforce the need to look at eyewitness testimony carefully,” said Tonegawa, “so that innocent people will not be incriminated.”

Tonegawa said he thinks that false memories with positive connotations likely form in the same way—a hypothesis he hopes to test with future experiments. In addition, given that false memories appear robust enough to compete with real memories, Tonegawa said he plans to investigate the factors that affect the relative strengths of the two types of memory.

How much of this kind of reality can the public take? Producers clearly see no end in sight, and the results are increasingly becoming more questionable.

This is what's called a ''reality-based'' series, a label that has less to do with reality than comforting formula. The cameras do not go to a real hospital. But three real doctors are on the production staff.

''What you are about to see is real,'' we were told once again.

His life shattered, he now has the dubious pleasure of knowing that, for some 20 minutes, he was the star of a television reality entertainment.

''On Trial'' opens with an announcer exclaiming that viewers are about to see ''Real people! Real Cases! Real Life!'' Mr. Clooney, a distinguished-looking fellow, fills in the pertinent facts.

Everything is designed, they say, to ''give the show its docudrama look.'' The show's regular staff of three doctors are depicted by actors.

Needless to say, medical problems and crises have long been popular on television, especially on soap operas. ''Family Medical Center'' merely dispenses with extraneous plot and character developments and goes right to the medical core. A press release is candid about the show's interpretation of reality: ''It will have suspense, conflict and a resolution, which in almost all cases will be a happy one.''

The show looks as real as television entertainment can possibly make it. Alert viewers, however, will note whizzing by in the final credits the following advisory: '' 'Family Medical Center' is a dramatization. The characters are fictional and bear no resemblance to persons living or dead.''

Television reality wears many masks. A key to the overall picture was provided by one of those actors who deceived Oprah Winfrey and Geraldo Rivera with false impersonations on air. Why not, he shrugged, it's all entertainment. Frightening but not beyond comprehension.

The question of what should be done with you is much easier to answer when we can definitively say what you are.

The crux of the issue boils down to this: Is Facebook’s normalization of hyper-transparency and information-oriented mode of self-definition conditioning young people to be submissive toward institutionalized forms of subject formation? Does it quell unrest in response to those power structures invested in telling you who and what you are? Will the young people of the future question social values if they are trained from a young age by technological demands to express their person in a corporately constructed template?

When we withhold belief because the evidence does not live up to the standards of science, we are skeptical. When we refuse to believe something, even in the face of what most others would take to be compelling evidence, we are engaging in denial. In most cases, we do this because at some level it upsets us to think that the theory is true.

The throes of denial must feel a lot like skepticism. The rest of the world “just doesn’t get it.” We are the ones being rigorous. How can others be so gullible in believing that something is “true” before all of the facts are in? Yet a warning should occur when these stars align and we find ourselves feeling self-righteous about a belief that apparently means more to us than the preservation of good standards of evidence

how to tell a fact from an opinion? By the time we sit down to evaluate the evidence for a scientific theory, it is probably too late. If we take the easy path in our thinking, it eventually becomes a habit. If we lie to others, sooner or later we may believe the lie ourselves. The real battle comes in training ourselves to embrace the right attitudes about belief formation in the first place, and for this we need to do a little philosophy.

a telltale sign of denialism: that these alleged skeptics usually have different standards of evidence for those theories that they want to believe

Surely few would willingly embrace the title of “denialist.” It sounds so much more rigorous and fair-minded to maintain one’s “skepticism.” To hold that the facts are not yet settled. That there is so much more that we do not know. That the science isn’t certain.

The problem here, however, is that this is based not only on a grave misunderstanding of science (which in a sense is never settled), but also of what it means to be a skeptic.

Doubting the overwhelming consensus of scientists on an empirical question, for which one has only the spottiest ideologically-motivated “evidence,” is not skepticism, it is the height of gullibility. It is to claim that it is much more likely that there is a vast conspiracy among thousands of climate scientists than that they have instead all merely arrived at the same conclusion because that is where they were led by the evidence.

Couldn’t the scientists nonetheless be wrong? Yes, of course. The history of science has shown us that any scientific theory (even Newton’s theory of gravity) can be wrong

this does not mean that one is a good skeptic merely for disbelieving the well-corroborated conclusions of science. To reject a cascade of scientific evidence that shows that the global temperature is warming and that humans are almost certainly the cause of it, is not good reasoning, even if some long-shot hypothesis comes along in 50 years to show us why we were wrong.

In scientific reasoning, there is such a thing as warrant. Our beliefs must be justified. This means that we should believe what the evidence tells us, even while science insists that we must also try our best to show how any given theory might be wrong. Science will sometimes miss the mark, but its successful track record suggests that there is no superior competitor in discovering the facts about the empirical world

When we cynically pretend to withhold belief long past the point at which ample evidence should have convinced us that something is true, we have stumbled past skepticism and landed in the realm of willful ignorance. This is not the realm of science, but of ideological crackpots

To try to cover up the obvious shortcomings of their profoundly antisocial pedagogical model, many business schools tack on courses in ethics, corporate social responsibility, and the like, then shrug their collective shoulders when their graduates behave in ways that would make Vikings and pirates blush.

The only truly socially responsible management curriculum would be one built from the ground up out of the liberal arts – economics, of course, but also history, philosophy, political science, psychology, and sociology – because those are the core disciplines of social scientific and humanistic inquiry.

Properly understood, they are not “subjects” but ways of thinking about human beings, their behaviors, their institutions (of which businesses are just a small subset), and the ways they interact with the natural world. Only intelligent people with broad and deep backgrounds in the liberal arts can consistently make ethical decisions that are good for stakeholders, consumers, and the world they share.

Precisely because they are not deeply rooted in the liberal arts, many business schools try to inculcate messages into the brains of their students that are unscientific, mere fashions that cycle into and then out of popularity.

No one can seriously purport to understand corporate X (finance, formation, governance, social responsibility, etc.) today who does not understand X’s origins and subsequent development. Often, then, the historian of corporate X is the real expert, not the business school professor who did a little consulting, a few interviews, and a survey.

Lurking somewhere in the background of most great business leaders, ones who helped their companies, their customers, and the world, is a liberal arts education.

Instead of forcing students to choose between a broad liberal arts degree or a business career, business schools and liberal arts departments ought to work together to integrate all methods of knowing into a seamless whole focused on key questions and problems important to us all

There is not a single question of importance in the business world that does not have economic, historical, philosophical, political, psychological, and sociological components that are absolutely crucial to making good (right and moral) decisions. So why continue to divide understanding of the real world into hoary compartments

What happened? Note that the subject matter was difficult, and the goal wasn’t pleasure but learning. Both factors make us read differently. When we focus, we slow down. We reread the hard bits. We stop and think. Each is easier with print than with a podcast.

Print also supports readers through difficult content via signals to organization like paragraphs and headings, conventions missing from audio.

although one core process of comprehension serves both listening and reading, difficult texts demand additional mental strategies. Print makes those strategies easier to use

But even with those changes, audiobooks won’t replace print because we use them differently

Eighty-one percent of audiobook listeners say they like to drive, work out or otherwise multitask while they listen. The human mind is not designed for doing two things simultaneously, so if we multitask, we’ll get gist, not subtleties.

Print may be best for lingering over words or ideas, but audiobooks add literacy to moments where there would otherwise be none

A great TED talk is reminiscent of a tent revival sermon. There’s the gathering of the curious and the hungry. Then a persistent human problem is introduced, one that, as the speaker gently explains, has deeper roots and wider implications than most listeners are prepared to admit. Once everyone has been confronted with this evidence of entropy, contemplated life’s fragility and the elusiveness of inner peace, a decision is called for: Will you remain complacent, or change?

on a pure emotional level I understand the appeal of sitting in a darkened room as a speaker pulls you into a crescendo of conviction that you can and will improve — and more attractive still, that your individual change for the better will make the whole world better.

TED talks routinely present problems of huge scale and scope — we imprison too many people; the rain forest is dying; look at all this garbage; we’re unhappy; we have Big Data and aren’t sure what to do with it — then wrap up tidily and tinily. Do this. Stop doing that

Instead of sola scriptura, TED and its ilk offer more of a buffet-style approach to moral formation. I’ve talked to people who say they’ve happily dispensed with God, and don’t even find the general idea comprehensible. But a few, having announced they’re free of cant, spend many nervous hours assembling authority structures and a sense of righteousness by bricolage and Fitbit, nonfiction book clubs and Facebook likes.

If I were 19 again, and experimenting with sacrilege for the first but not the last time, I would heed some advice that was given to me then: “If you’re going to be an atheist, you should be having a lot more fun.”

But the truth is, now is a fun time to be a skeptic among true believers, since there are so many types of true believers to choose from.
