Patterns that didn’t change one generation to the next, Dr. Conway called still lifes — such as the four-celled block, the six-celled beehive or the eight-celled pond. Patterns that took a long time to stabilize, he called methuselahs.

The second thing Life shows us is something that Darwin hit upon when he was looking at Life, the organic version. Complexity arises from simplicity!

I first encountered Life at the Exploratorium in San Francisco in 1978. I was hooked immediately by the thing that has always hooked me — watching complexity arise out of simplicity.

Life shows you two things. The first is sensitivity to initial conditions. A tiny change in the rules can produce a huge difference in the output, ranging from complete destruction (no dots) through stasis (a frozen pattern) to patterns that keep changing as they unfold.

Life shows us complex virtual “organisms” arising out of the interaction of a few simple rules — so goodbye “Intelligent Design.”

I’ve wondered for decades what one could learn from all that Life hacking. I recently realized it’s a great place to try to develop “meta-engineering” — to see if there are general principles that govern the advance of engineering and help us predict the overall future trajectory of technology.

Given that Conway’s proof that the Game of Life can be made to simulate a Universal Computer — that is, it could be “programmed” to carry out any computation that a traditional computer can do — the extremely simple rules can give rise to the most complex and most unpredictable behavior possible. This means that there are certain properties of the Game of Life that can never be predicted, even in principle!

I use the Game of Life to make vivid for my students the ideas of determinism, higher-order patterns and information. One of its great features is that nothing is hidden; there are no black boxes in Life, so you know from the outset that anything that you can get to happen in the Life world is completely unmysterious and explicable in terms of a very large number of simple steps by small items.

In Thomas Pynchon’s novel “Gravity’s Rainbow,” a character says, “But you had taken on a greater and more harmful illusion. The illusion of control. That A could do B. But that was false. Completely. No one can do. Things only happen.”This is compelling but wrong, and Life is a great way of showing this.

In Life, we might say, things only happen at the pixel level; nothing controls anything, nothing does anything. But that doesn’t mean that there is no such thing as action, as control; it means that these are higher-level phenomena composed (entirely, with no magic) from things that only happen.

it did have a big impact on beginner programmers, like me in the 90s, giving them a sense of wonder and a kind of confidence that some easy-to-code math models can produce complex and beautiful results. It’s like a starter kit for future software engineers and hackers, together with Mandelbrot Set, Lorenz Attractor, et cetera.

if we think about our everyday life, about corporations and governments, the cultural and technical infrastructures humans built for thousands of years, they are not unlike the incredible machines that are engineered in Life.

In normal times, they are stable and we can keep building stuff one component upon another, but in harder times like this pandemic or a new Cold War, we need something that is more resilient and can prepare for the unpreparable. That would need changes in our “rules of life,” which we take for granted.

That’s what chaos is about. The Game of Life, or a kinky dynamical system like a pair of pendulums, or a candle flame, or an ocean wave, or the growth of a plant — they aren’t readily predictable. But they are not random. They do obey laws, and there are certain kinds of patterns — chaotic attractors — that they tend to produce. But again, unpredictable is not random. An important and subtle distinction which changed my whole view of the world.

William Poundstone— Author of “The Recursive Universe: Cosmic Complexity and the Limits of Scientific Knowledge,” Los Angeles, Calif.

The Game of Life’s pulsing, pyrotechnic constellations are classic examples of emergent phenomena, introduced decades before that adjective became a buzzword.

Fifty years later, the misfortunes of 2020 are the stuff of memes. The biggest challenges facing us today are emergent: viruses leaping from species to species; the abrupt onset of wildfires and tropical storms as a consequence of a small rise in temperature; economies in which billions of free transactions lead to staggering concentrations of wealth; an internet that becomes more fraught with hazard each year

Looming behind it all is our collective vision of an artificial intelligence-fueled future that is certain to come with surprises, not all of them pleasant.

The name Conway chose — the Game of Life — frames his invention as a metaphor. But I’m not sure that even he anticipated how relevant Life would become, and that in 50 years we’d all be playing an emergent game of life and death.

start with epistemic bubbles

That omission might be purposeful

But that omission can also be entirely inadvertent. Even if we’re not actively trying to avoid disagreement, our Facebook friends tend to share our views and interests

An ‘echo chamber’ is a social structure from which other relevant voices have been actively discredited. Where an epistemic bubble merely omits contrary views, an echo chamber brings its members to actively distrust outsiders.

an echo chamber is something like a cult. A cult isolates its members by actively alienating them from any outside sources. Those outside are actively labelled as malignant and untrustworthy.

In epistemic bubbles, other voices are not heard; in echo chambers, other voices are actively undermined.

The way to break an echo chamber is not to wave “the facts” in the faces of its members. It is to attack the echo chamber at its root and repair that broken trust.

Looking to others for corroboration is a basic method for checking whether one has reasoned well or badly

They have been in the limelight lately, most famously in Eli Pariser’s The Filter Bubble (2011) and Cass Sunstein’s #Republic: Divided Democracy in the Age of Social Media (2017).

The general gist: we get much of our news from Facebook feeds and similar sorts of social media. Our Facebook feed consists mostly of our friends and colleagues, the majority of whom share our own political and cultural views

various algorithms behind the scenes, such as those inside Google search, invisibly personalise our searches, making it more likely that we’ll see only what we want to see. These processes all impose filters on information.

Such filters aren’t necessarily bad. The world is overstuffed with information, and one can’t sort through it all by oneself: filters need to be outsourced.

That’s why we all depend on extended social networks to deliver us knowledge

any such informational network needs the right sort of broadness and variety to work

Each individual person in my network might be superbly reliable about her particular informational patch but, as an aggregate structure, my network lacks what Sanford Goldberg in his book Relying on Others (2010) calls ‘coverage-reliability’. It doesn’t deliver to me a sufficiently broad and representative coverage of all the relevant information.

Epistemic bubbles also threaten us with a second danger: excessive self-confidence.

An ‘epistemic bubble’ is an informational network from which relevant voices have been excluded by omission

Suppose that I believe that the Paleo diet is the greatest diet of all time. I assemble a Facebook group called ‘Great Health Facts!’ and fill it only with people who already believe that Paleo is the best diet. The fact that everybody in that group agrees with me about Paleo shouldn’t increase my confidence level one bit. They’re not mere copies – they actually might have reached their conclusions independently – but their agreement can be entirely explained by my method of selection.

Luckily, though, epistemic bubbles are easily shattered. We can pop an epistemic bubble simply by exposing its members to the information and arguments that they’ve missed.

echo chambers are a far more pernicious and robust phenomenon.

amieson and Cappella’s book is the first empirical study into how echo chambers function

echo chambers work by systematically alienating their members from all outside epistemic sources.

Their research centres on Rush Limbaugh, a wildly successful conservative firebrand in the United States, along with Fox News and related media

His constant attacks on the ‘mainstream media’ are attempts to discredit all other sources of knowledge. He systematically undermines the integrity of anybody who expresses any kind of contrary view.

outsiders are not simply mistaken – they are malicious, manipulative and actively working to destroy Limbaugh and his followers. The resulting worldview is one of deeply opposed force, an all-or-nothing war between good and evil

The result is a rather striking parallel to the techniques of emotional isolation typically practised in cult indoctrination

cult indoctrination involves new cult members being brought to distrust all non-cult members. This provides a social buffer against any attempts to extract the indoctrinated person from the cult.

The echo chamber doesn’t need any bad connectivity to function. Limbaugh’s followers have full access to outside sources of information

As Elijah Millgram argues in The Great Endarkenment (2015), modern knowledge depends on trusting long chains of experts. And no single person is in the position to check up on the reliability of every member of that chain

Their worldview can survive exposure to those outside voices because their belief system has prepared them for such intellectual onslaught.

exposure to contrary views could actually reinforce their views. Limbaugh might offer his followers a conspiracy theory: anybody who criticises him is doing it at the behest of a secret cabal of evil elites, which has already seized control of the mainstream media.

Perversely, exposure to outsiders with contrary views can thus increase echo-chamber members’ confidence in their insider sources, and hence their attachment to their worldview.

‘evidential pre-emption’. What’s happening is a kind of intellectual judo, in which the power and enthusiasm of contrary voices are turned against those contrary voices through a carefully rigged internal structure of belief.

One might be tempted to think that the solution is just more intellectual autonomy. Echo chambers arise because we trust others too much, so the solution is to start thinking for ourselves.

that kind of radical intellectual autonomy is a pipe dream. If the philosophical study of knowledge has taught us anything in the past half-century, it is that we are irredeemably dependent on each other in almost every domain of knowledge

Limbaugh’s followers regularly read – but do not accept – mainstream and liberal news sources. They are isolated, not by selective exposure, but by changes in who they accept as authorities, experts and trusted sources.

we depend on a vastly complicated social structure of trust. We must trust each other, but, as the philosopher Annette Baier says, that trust makes us vulnerable. Echo chambers operate as a kind of social parasite on that vulnerability, taking advantage of our epistemic condition and social dependency.

I am quite confident that there are plenty of echo chambers on the political Left. More importantly, nothing about echo chambers restricts them to the arena of politics

The world of anti-vaccination is clearly an echo chamber, and it is one that crosses political lines. I’ve also encountered echo chambers on topics as broad as diet (Paleo!), exercise technique (CrossFit!), breastfeeding, some academic intellectual traditions, and many, many more

Here’s a basic check: does a community’s belief system actively undermine the trustworthiness of any outsiders who don’t subscribe to its central dogmas? Then it’s probably an echo chamber.

much of the recent analysis has lumped epistemic bubbles together with echo chambers into a single, unified phenomenon. But it is absolutely crucial to distinguish between the two.

Epistemic bubbles are rather ramshackle; they go up easily, and they collapse easily

Echo chambers are far more pernicious and far more robust. They can start to seem almost like living things. Their belief systems provide structural integrity, resilience and active responses to outside attacks

the two phenomena can also exist independently. And of the events we’re most worried about, it’s the echo-chamber effects that are really causing most of the trouble.

new data does, in fact, seem to show that people on Facebook actually do see posts from the other side, or that people often visit websites with opposite political affiliation.

their basis for evaluation – their background beliefs about whom to trust – are radically different. They are not irrational, but systematically misinformed about where to place their trust.

Many people have claimed that we have entered an era of ‘post-truth’.

Not only do some political figures seem to speak with a blatant disregard for the facts, but their supporters seem utterly unswayed by evidence. It seems, to some, that truth no longer matters.

This is an explanation in terms of total irrationality. To accept it, you must believe that a great number of people have lost all interest in evidence or investigation, and have fallen away from the ways of reason.

echo chambers offers a less damning and far more modest explanation. The apparent ‘post-truth’ attitude can be explained as the result of the manipulations of trust wrought by echo chambers.

We don’t have to attribute a complete disinterest in facts, evidence or reason to explain the post-truth attitude. We simply have to attribute to certain communities a vastly divergent set of trusted authorities.

An echo chamber doesn’t destroy their members’ interest in the truth; it merely manipulates whom they trust and changes whom they accept as trustworthy sources and institutions.

in many ways, echo-chamber members are following reasonable and rational procedures of enquiry. They’re engaging in critical reasoning. They’re questioning, they’re evaluating sources for themselves, they’re assessing different pathways to information. They are critically examining those who claim expertise and trustworthiness, using what they already know about the world

none of this weighs against the existence of echo chambers. We should not dismiss the threat of echo chambers based only on evidence about connectivity and exposure.

Notice how different what’s going on here is from, say, Orwellian doublespeak, a deliberately ambiguous, euphemism-filled language designed to hide the intent of the speaker.

echo chambers don’t trade in vague, ambiguous pseudo-speech. We should expect that echo chambers would deliver crisp, clear, unambiguous claims about who is trustworthy and who is not

clearly articulated conspiracy theories, and crisply worded accusations of an outside world rife with untrustworthiness and corruption.

Once an echo chamber starts to grip a person, its mechanisms will reinforce themselves.

In an epistemically healthy life, the variety of our informational sources will put an upper limit to how much we’re willing to trust any single person. Everybody’s fallible; a healthy informational network tends to discover people’s mistakes and point them out. This puts an upper ceiling on how much you can trust even your most beloved leader

nside an echo chamber, that upper ceiling disappears.

Being caught in an echo chamber is not always the result of laziness or bad faith. Imagine, for instance, that somebody has been raised and educated entirely inside an echo chamber

when the child finally comes into contact with the larger world – say, as a teenager – the echo chamber’s worldview is firmly in place. That teenager will distrust all sources outside her echo chamber, and she will have gotten there by following normal procedures for trust and learning.

It certainly seems like our teenager is behaving reasonably. She could be going about her intellectual life in perfectly good faith. She might be intellectually voracious, seeking out new sources, investigating them, and evaluating them using what she already knows.

The worry is that she’s intellectually trapped. Her earnest attempts at intellectual investigation are led astray by her upbringing and the social structure in which she is embedded.

Echo chambers might function like addiction, under certain accounts. It might be irrational to become addicted, but all it takes is a momentary lapse – once you’re addicted, your internal landscape is sufficiently rearranged such that it’s rational to continue with your addiction

Similarly, all it takes to enter an echo chamber is a momentary lapse of intellectual vigilance. Once you’re in, the echo chamber’s belief systems function as a trap, making future acts of intellectual vigilance only reinforce the echo chamber’s worldview.

There is at least one possible escape route, however. Notice that the logic of the echo chamber depends on the order in which we encounter the evidence. An echo chamber can bring our teenager to discredit outside beliefs precisely because she encountered the echo chamber’s claims first. Imagine a counterpart to our teenager who was raised outside of the echo chamber and exposed to a wide range of beliefs. Our free-range counterpart would, when she encounters that same echo chamber, likely see its many flaws

Those caught in an echo chamber are giving far too much weight to the evidence they encounter first, just because it’s first. Rationally, they should reconsider their beliefs without that arbitrary preference. But how does one enforce such informational a-historicity?

The escape route is a modified version of René Descartes’s infamous method.

Meditations on First Philosophy (1641). He had come to realise that many of the beliefs he had acquired in his early life were false. But early beliefs lead to all sorts of other beliefs, and any early falsehoods he’d accepted had surely infected the rest of his belief system.

The only solution, thought Descartes, was to throw all his beliefs away and start over again from scratch.

He could start over, trusting nothing and no one except those things that he could be entirely certain of, and stamping out those sneaky falsehoods once and for all. Let’s call this the Cartesian epistemic reboot.

Notice how close Descartes’s problem is to our hapless teenager’s, and how useful the solution might be. Our teenager, like Descartes, has problematic beliefs acquired in early childhood. These beliefs have infected outwards, infesting that teenager’s whole belief system. Our teenager, too, needs to throw everything away, and start over again.

Let’s call the modernised version of Descartes’s methodology the social-epistemic reboot.

when she starts from scratch, we won’t demand that she trust only what she’s absolutely certain of, nor will we demand that she go it alone

For the social reboot, she can proceed, after throwing everything away, in an utterly mundane way – trusting her senses, trusting others. But she must begin afresh socially – she must reconsider all possible sources of information with a presumptively equanimous eye. She must take the posture of a cognitive newborn, open and equally trusting to all outside sources

we’re not asking people to change their basic methods for learning about the world. They are permitted to trust, and trust freely. But after the social reboot, that trust will not be narrowly confined and deeply conditioned by the particular people they happened to be raised by.

Such a profound deep-cleanse of one’s whole belief system seems to be what’s actually required to escape. Look at the many stories of people leaving cults and echo chambers

Take, for example, the story of Derek Black in Florida – raised by a neo-Nazi father, and groomed from childhood to be a neo-Nazi leader. Black left the movement by, basically, performing a social reboot. He completely abandoned everything he’d believed in, and spent years building a new belief system from scratch. He immersed himself broadly and open-mindedly in everything he’d missed – pop culture, Arabic literature, the mainstream media, rap – all with an overall attitude of generosity and trust.

It was the project of years and a major act of self-reconstruction, but those extraordinary lengths might just be what’s actually required to undo the effects of an echo-chambered upbringing.

we need to attack the root, the systems of discredit themselves, and restore trust in some outside voices.

Stories of actual escapes from echo chambers often turn on particular encounters – moments when the echo-chambered individual starts to trust somebody on the outside.

Black’s is case in point. By high school, he was already something of a star on neo-Nazi media, with his own radio talk-show. He went on to college, openly neo-Nazi, and was shunned by almost every other student in his community college. But then Matthew Stevenson, a Jewish fellow undergraduate, started inviting Black to Stevenson’s Shabbat dinners. In Black’s telling, Stevenson was unfailingly kind, open and generous, and slowly earned Black’s trust. This was the seed, says Black, that led to a massive intellectual upheaval – a slow-dawning realisation of the depths to which he had been misled

Similarly, accounts of people leaving echo-chambered homophobia rarely involve them encountering some institutionally reported fact. Rather, they tend to revolve around personal encounters – a child, a family member, a close friend coming out.

hese encounters matter because a personal connection comes with a substantial store of trust.

We don’t simply trust people as educated experts in a field – we rely on their goodwill. And this is why trust, rather than mere reliability, is the key concept

goodwill is a general feature of a person’s character. If I demonstrate goodwill in action, then you have some reason to think that I also have goodwill in matters of thought and knowledge.

f one can demonstrate goodwill to an echo-chambered member – as Stevenson did with Black – then perhaps one can start to pierce that echo chamber.

the path I’m describing is a winding, narrow and fragile one. There is no guarantee that such trust can be established, and no clear path to its being established systematically.

what we’ve found here isn’t an escape route at all. It depends on the intervention of another. This path is not even one an echo-chamber member can trigger on her own; it is only a whisper-thin hope for rescue from the outside.

Haidt isn’t helping himself any. The term “culture of victimhood” reminds many people of the “snowflake” insult, the idea than anyone from a marginalized background who complains about injustice is really just self-involved and weak.

I find his predictions about how these dynamics will somehow undermine American capitalism to be unconvincing, running towards bizarre. If social media is making our kids depressed and anxious, that is the reason to be concerned, not some tangled logic about national greatness.

I think that suffering is the only truly universal endowment of the human species.

ecause Haidt talked about a culture of victimhood, he was immediately coded as right-wing, which is to say on the wrong side of the culture war

(The piece notes that the age at which children are allowed to play outside alone has moved from 7 or 8 to 10 or 12 in short order.)

the critics of someone like Haidt, the most coherent criticism they mount is that talk of toughness and resilience can be used opportunistically to dismiss demands for justice. “You just need to toughen up” is not, obviously, a constructive, good-faith response to a demand that the police stop killing unarmed Black people

I don’t think that’s the version Haidt is articulating

Yes, we must do all we can to reduce injustice, and we need to be compassionate to everyone. But we also need to understand that no political movement, no matter how effective, can ever end suffering and thus obviate the need for resilience.

I’m really not a fan of therapy culture, where the imperatives and vocabulary and purpose of therapy are now assumed to be necessary in every domain of human affairs. But that’s not because I think therapy is bad; I think therapy, as therapy, is very good. It’s because I think everything can’t be therapy, and the effort to make everything therapy will have the perverse effect of making nothing therapy.

Irony — postmodern or any other — is a brief against affirmation, against the unsophisticated embrace of positive (unqualified) values.

No one has seen this more clearly than David Foster Wallace, who complains that irony “serves an exclusively negative function,” but is “singularly unuseful when it comes to replace the hypocrisies it debunks” (“E Unibus Pluram,” Review of Contemporary Fiction, 1993). Irony, he adds, is “unmeaty”; that is, it has nothing solid inside it and is committed to having nothing inside it. Few artists, Wallace says, “dare to try to talk about ways of redeeming what’s wrong, because they’ll look sentimental and naïve to all the weary ironists.” But perhaps there is hope. “The next real … ‘rebels’ … might well emerge as some weird bunch of ‘antirebels,’ born oglers who dare to back away from ironic watching, who have the childish gall actually to endorse single-entendre values. Who treat old untrendy human troubles and emotions with reverence and conviction” (“E Pluribus Unam”).

in general what he argues is that if you take a look at animal cognition, human too, it's computational systems. Therefore, you want to look the units of computation. Think about a Turing machine, say, which is the simplest form of computation, you have to find units that have properties like "read", "write" and "address." That's the minimal computational unit, so you got to look in the brain for those. You're never going to find them if you look for strengthening of synaptic connections or field properties, and so on. You've got to start by looking for what's there and what's working and you see that from Marr's highest level.

it's basically in the spirit of Marr's analysis. So when you're studying vision, he argues, you first ask what kind of computational tasks is the visual system carrying out. And then you look for an algorithm that might carry out those computations and finally you search for mechanisms of the kind that would make the algorithm work. Otherwise, you may never find anything.

"Good Old Fashioned AI," as it's labeled now, made strong use of formalisms in the tradition of Gottlob Frege and Bertrand Russell, mathematical logic for example, or derivatives of it, like nonmonotonic reasoning and so on. It's interesting from a history of science perspective that even very recently, these approaches have been almost wiped out from the mainstream and have been largely replaced -- in the field that calls itself AI now -- by probabilistic and statistical models. My question is, what do you think explains that shift and is it a step in the right direction?

AI and robotics got to the point where you could actually do things that were useful, so it turned to the practical applications and somewhat, maybe not abandoned, but put to the side, the more fundamental scientific questions, just caught up in the success of the technology and achieving specific goals.

The approximating unanalyzed data kind is sort of a new approach, not totally, there's things like it in the past. It's basically a new approach that has been accelerated by the existence of massive memories, very rapid processing, which enables you to do things like this that you couldn't have done by hand. But I think, myself, that it is leading subjects like computational cognitive science into a direction of maybe some practical applicability... ..in engineering? Chomsky: ...But away from understanding.

I was very skeptical about the original work. I thought it was first of all way too optimistic, it was assuming you could achieve things that required real understanding of systems that were barely understood, and you just can't get to that understanding by throwing a complicated machine at it.

if success is defined as getting a fair approximation to a mass of chaotic unanalyzed data, then it's way better to do it this way than to do it the way the physicists do, you know, no thought experiments about frictionless planes and so on and so forth. But you won't get the kind of understanding that the sciences have always been aimed at -- what you'll get at is an approximation to what's happening.

Suppose you want to predict tomorrow's weather. One way to do it is okay I'll get my statistical priors, if you like, there's a high probability that tomorrow's weather here will be the same as it was yesterday in Cleveland, so I'll stick that in, and where the sun is will have some effect, so I'll stick that in, and you get a bunch of assumptions like that, you run the experiment, you look at it over and over again, you correct it by Bayesian methods, you get better priors. You get a pretty good approximation of what tomorrow's weather is going to be. That's not what meteorologists do -- they want to understand how it's working. And these are just two different concepts of what success means, of what achievement is.

if you get more and more data, and better and better statistics, you can get a better and better approximation to some immense corpus of text, like everything in The Wall Street Journal archives -- but you learn nothing about the language.

the right approach, is to try to see if you can understand what the fundamental principles are that deal with the core properties, and recognize that in the actual usage, there's going to be a thousand other variables intervening -- kind of like what's happening outside the window, and you'll sort of tack those on later on if you want better approximations, that's a different approach.

take a concrete example of a new field in neuroscience, called Connectomics, where the goal is to find the wiring diagram of very complex organisms, find the connectivity of all the neurons in say human cerebral cortex, or mouse cortex. This approach was criticized by Sidney Brenner, who in many ways is [historically] one of the originators of the approach. Advocates of this field don't stop to ask if the wiring diagram is the right level of abstraction -- maybe it's no

if you went to MIT in the 1960s, or now, it's completely different. No matter what engineering field you're in, you learn the same basic science and mathematics. And then maybe you learn a little bit about how to apply it. But that's a very different approach. And it resulted maybe from the fact that really for the first time in history, the basic sciences, like physics, had something really to tell engineers. And besides, technologies began to change very fast, so not very much point in learning the technologies of today if it's going to be different 10 years from now. So you have to learn the fundamental science that's going to be applicable to whatever comes along next. And the same thing pretty much happened in medicine.

that's the kind of transition from something like an art, that you learn how to practice -- an analog would be trying to match some data that you don't understand, in some fashion, maybe building something that will work -- to science, what happened in the modern period, roughly Galilean science.

it turns out that there actually are neural circuits which are reacting to particular kinds of rhythm, which happen to show up in language, like syllable length and so on. And there's some evidence that that's one of the first things that the infant brain is seeking -- rhythmic structures. And going back to Gallistel and Marr, its got some computational system inside which is saying "okay, here's what I do with these things" and say, by nine months, the typical infant has rejected -- eliminated from its repertoire -- the phonetic distinctions that aren't used in its own language.

people like Shimon Ullman discovered some pretty remarkable things like the rigidity principle. You're not going to find that by statistical analysis of data. But he did find it by carefully designed experiments. Then you look for the neurophysiology, and see if you can find something there that carries out these computations. I think it's the same in language, the same in studying our arithmetical capacity, planning, almost anything you look at. Just trying to deal with the unanalyzed chaotic data is unlikely to get you anywhere, just like as it wouldn't have gotten Galileo anywhere.

with regard to cognitive science, we're kind of pre-Galilean, just beginning to open up the subject

You can invent a world -- I don't think it's our world -- but you can invent a world in which nothing happens except random changes in objects and selection on the basis of external forces. I don't think that's the way our world works, I don't think it's the way any biologist thinks it is. There are all kind of ways in which natural law imposes channels within which selection can take place, and some things can happen and other things don't happen. Plenty of things that go on in the biology in organisms aren't like this. So take the first step, meiosis. Why do cells split into spheres and not cubes? It's not random mutation and natural selection; it's a law of physics. There's no reason to think that laws of physics stop there, they work all the way through. Well, they constrain the biology, sure. Chomsky: Okay, well then it's not just random mutation and selection. It's random mutation, selection, and everything that matters, like laws of physics.

What I think is valuable is the history of science. I think we learn a lot of things from the history of science that can be very valuable to the emerging sciences. Particularly when we realize that in say, the emerging cognitive sciences, we really are in a kind of pre-Galilean stage. We don't know wh

at we're looking for anymore than Galileo did, and there's a lot to learn from that.

More F.S. Oliver: Nothing in politics is sadder than: the man of sterling character whose genius is so antipathetic to the particular emergency in which he finds himself as to stupefy his thoughts and paralyze his actions. He drifts to disaster, grappling blindfolded which are beyond his comprehension, failing without really fighting.

Bad choices over the past decade by Republican political leaders opened the way to Donald Trump, yes.  For a decade, Republican voters have signaled they wanted to protect Medicare, cut immigration, fight fewer wars, and nominate no more Bushes. Their party leaders interpreted those signals as demands to cut Medicare, increase immigration, put boots on the ground in Syria, and nominate another Bush.

Their task ahead, in the Biblical phrase, is to pluck the brands from the fire—rescue as much of their party as can be rescued—while simultaneously minimizing the damage to party and country by the nominee their rank-and-file has imposed on them. They need to maneuver so that Trump’s defeat is as solitary as possible, and so that he cannot shift the blame for the failure he has earned onto the heads of others

Trump’s taught Republican politicians that they’ve neglected the interests and values of their core supporters. He’s demonstrated that much of their party ideology is obsolete, and that their language no longer moves their voters. He’s proven that their party is less culturally conservative than they believed, less hostile to social insurance than they imagined, and more worried about the economic and social costs of mass migration than they realized. Those are valuable lessons that need to be absorbed and pondered.

He’s also demonstrated that he himself is a dangerous person

To save themselves and their country, Republican politicians will have to rediscover the politician’s arts of deftness, flexibility, and self-preservation—while stealthily hastening Trump toward the defeat that almost certainly awaits him in November.

That’s a big job and a hard job, all the harder because they cannot acknowledge what they are doing. They will seem to help Trump win, while actually working to ensure he fail

What Walter Lippman said of presidents is really true of all politicians: They are not “working through noble institutions to dear ends … but trying to grind out a few crude results from a decadent political machine.”

The harms they stop are more important than the good they cannot achieve. What they’re called upon to do is to practice statesmanship without fine phrases; to protect the republic without receiving any credit for it

Dozens of popular books by nonexperts have filled the void, many claiming that IQ—which after more than a century remains the dominant metric for intelligence—predicts nothing important or that intelligence is simply too complex and subtle to be measured.

evidence points toward a strong genetic component in IQ. Based on studies of twins, siblings, and adoption, contemporary estimates put the heritability of IQ at 50 to 80 percent

intelligence has a genetic recipe

“Do you know any Perl?” Li asked him. Perl is a programming language often used to analyze genomic data. Zhao admitted he did not; in fact, he had no programming skills at all. Li handed him a massive textbook, Programming Perl. There were only two weeks left in the camp, so this would get rid of the kid for good. A few days later, Zhao returned. “I finished it,” he said. “The problems are kind of boring. Do you have anything harder?” Perl is a famously complicated language that takes university students a full year to learn.

So Li gave him a large DNA data set and a complicated statistical problem. That should do it. But Zhao returned later that day. “Finished.” Not only was it finished—and correct—but Zhao had even built a slick interface on top of the data.

driven by a fascination with kids who are born smart; he wants to know what makes them—and by extension, himself—the way they are.

“I think the differences are still greater than the similarities,” he says. “Hitler was not only more intelligent, but craftier. He was not just a powerful orator, but a talented actor who succeeded in winning over various social milieus. So not just the economically threatened lower middle classes which Trump targeted, but also the upper middle classes. Hitler had many supporters in the German aristocracy.”

Trump was also democratically elected, while Hitler never had a majority vote. “He was appointed by the president of the German Reich.” Then there’s the fact that Trump does not lead a party “which is unconditionally committed to him”.

“A further obvious difference is that Trump doesn’t have a private militia, as Hitler did with the SA, which he used in his first months after coming to power to settle scores with his opponents, like the Communists and Social Democrats. You can’t possibly imagine something similar with Trump – that he’ll be locking Democrats up into concentration camps

“Finally, the American constitution is based on a system of checks and balances. It remains to be seen how far Congress will really limit Trump or if, as is feared, he can override it. It was different with Hitler, who, as we know, managed to eliminate all resistance in the shortest space of time and effectively establish himself as an all-powerful dictator. Within a few months, there was effectively no longer any opposition.”

“Hitler profited from the fact that his opponents always underestimated him,” Ullrich explains. “His conservative allies in government assumed they could tame or ‘civilise’ him – that once he became chancellor he’d become vernünftig (meaning sensible, reasonable). Very quickly it became clear that was an illusion.”

“There were many situations where he could have been stopped. For example in 1923 after the failed Munich putsch – if he’d served his full prison sentence of several years, he wouldn’t have made a political comeback. Instead, he only spent a few months behind bars, [having been released after political pressure] and could rebuild his movement.”

The western powers made the same mistake with their appeasement politics, indecision and indulgence. “In the 1930s Hitler strengthened, rather than weakened, his aggressive intentions,” Ullrich says. “So you could learn from this that you have to react faster and much more vigorously than was the case at the time.”

llrich also contends that if Hindenburg, the president of the Reich, had allowed Chancellor Brüning, of the Centre party, to remain chancellor to the end of 1934, rather than responding to pressure from conservatives to dismiss him in 1932, “then the peak of the economic crisis would have passed and it would have been very questionable whether Hitler could still have come to power”.

At the same time, Hitler’s ascent was no mere fluke. “There were powerful forces in the big industries, but also in the landowning class and the armed forces, which approved of a fascist solution to the crisis.”

If fascism “now just means aggressive nationalism, racism, patriarchy and authoritarianism, then maybe it is back on the agenda,” Bosworth continues. But today’s context is fundamentally different

Today’s “alt-right” agitators “live in a neoliberal global order where the slogan, ‘all for the market, nothing outside the market, no one against the market’ is far more unquestionably accepted than the old fascist slogan of ‘all for the state, nothing outside the state, no one against the state’”.

“What is that if it’s not racially authoritarian?” asks Schama. “If you want to call it fascist, fine. I don’t really care if it’s called that or not. It’s authoritarian, you know, ferociously authoritarian.”

Schama also points to deeply worrying messaging, such as “the parallel universe of lies which are habitual, massive, cumulative”; the criminalization of political opponents; the threat to change the libel laws against the press and the demonization of different racial and ethnic groups, going as far as proposing a Muslim registry.

Schama is clear: Trump is obviously not Hitler. “But, you know, if you like, he’s an entertainment fascist, which may be less sinister but is actually in the end more dangerous. If you’re not looking for jackboots and swastikas – although swastikas are indeed appearing – there’s a kind of laundry list of things which are truly sinister and authoritarian and not business as usual.”

Don’t ignore what people vote fo

f you’re of German heritage, it’s hard to understand how so many people could have bought Mein Kampf and gone on to vote for Hitler. Maybe no one really read it, or got beyond the first few pages of bluster, or took antisemitism seriously, you tell yourself. “Or they liked what he said,

“I think one of the mistakes this time around would be not to think that the people who voted for Trump were serious. They may have been serious for different reasons, but it would be a big mistake not to try and figure out what their reasons were.

Hitler presented himself as a “messiah” offering the public “salvation”, Ullrich points out. With austerity and hostility to the EU and to immigrants riding high, there is fertile ground for European populists next year to seduce with equally simplistic, sweeping “solutions”.

The problem, in Mazower’s view, is that establishment politicians currently have no response

“The Gestapo was piddling compared with the size and reach of surveillance equipment and operations today,

“Very belatedly, everyone is waking up to the fact that there was a general assumption that no government in the west would fall into the wrong hands, that it was safe to acquiesce in this huge expansion of surveillance capabilities, and the debate wasn’t as vigorous as it could have been.”

“Now, there is a lot of discussion about allowing this kind of surveillance apparatus in the wrong hands,” he adds. “And we’ve woken up to this a bit late in the day.”

Ullrich calls crises, “the elixir of rightwing populists”, and urges that politicians “do everything they can to correct the inequalities and social injustice which have arisen in the course of extreme financial capitalism in western countries”

Jane Caplan, a history professor at Oxford University who has written about Trump and fascism, highlights the want of “dissenting voices against marketisation and neoliberalism

The failure to resist the incursion of the market as the only criterion for political utility, or economic utility, has been pretty comprehensive.

Paranoia, bullying and intimidation are a hallmark of authoritarian regimes. They are also alive and well in our culture today, where online trolls, violent thugs at rallies, threats of expensive libel action and of course terrorist acts are equally effective in getting individuals and the press to self-censor.

When I wrote in August 2015 that Mr. Trump was a cartoon version of every left-wing media stereotype of the reactionary, nativist, misogynist right, I thought that I was well within the mainstream of conservative thought — only to find conservative Trump critics denounced for apostasy by a right that decided that it was comfortable with embracing Trumpism.

relatively few of my listeners bought into the crude nativism Mr. Trump was selling at his rallies.

What they did buy into was the argument that this was a “binary choice.” No matter how bad Mr. Trump was, my listeners argued, he could not possibly be as bad as Mrs. Clinton. You simply cannot overstate this as a factor in the final outcome

Even among Republicans who had no illusions about Mr. Trump’s character or judgment, the demands of that tribal loyalty took precedence. To resist was an act of betrayal.

In this binary tribal world, where everything is at stake, everything is in play, there is no room for quibbles about character, or truth, or principles.

If everything — the Supreme Court, the fate of Western civilization, the survival of the planet — depends on tribal victory, then neither individuals nor ideas can be determinative.

As our politics have become more polarized, the essential loyalties shift from ideas, to parties, to tribes, to individuals. Nothing else ultimately matters.

For many listeners, nothing was worse than Hillary Clinton. Two decades of vilification had taken their toll: Listeners whom I knew to be decent, thoughtful individuals began forwarding stories with conspiracy theories about President Obama and Mrs. Clinton — that he was a secret Muslim, that she ran a child sex ring out of a pizza parlor. When I tried to point out that such stories were demonstrably false, they generally refused to accept evidence that came from outside their bubble. The echo chamber had morphed into a full-blown alternate reality silo of conspiracy theories, fake news and propaganda.

In this political universe, voters accept that they must tolerate bizarre behavior, dishonesty, crudity and cruelty, because the other side is always worse; the stakes are such that no qualms can get in the way of the greater cause.

When it became clear that I was going to remain #NeverTrump, conservatives I had known and worked with for more than two decades organized boycotts of my show. One prominent G.O.P. activist sent out an email blast calling me a “Judas goat,” and calling for postelection retribution.

And then, there was social media. Unless you have experienced it, it’s difficult to describe the virulence of the Twitter storms that were unleashed on Trump skeptics. In my timelines, I found myself called a “cuckservative,” a favorite gibe of white nationalists; and someone Photoshopped my face into a gas chamber. Under the withering fire of the trolls, one conservative commentator and Republican political leader after another fell in line.

we had succeeded in persuading our audiences to ignore and discount any information from the mainstream media. Over time, we’d succeeded in delegitimizing the media altogether — all the normal guideposts were down, the referees discredited.

That left a void that we conservatives failed to fill. For years, we ignored the birthers, the racists, the truthers and other conspiracy theorists who indulged fantasies of Mr. Obama’s secret Muslim plot to subvert Christendom, or who peddled baseless tales of Mrs. Clinton’s murder victims. Rather than confront the purveyors of such disinformation, we changed the channel because, after all, they were our allies, whose quirks could be allowed or at least ignored

We destroyed our own immunity to fake news, while empowering the worst and most reckless voices on the right.

This was not mere naïveté. It was also a moral failure, one that now lies at the heart of the conservative movement even in its moment of apparent electoral triumph. Now that the election is over, don’t expect any profiles in courage from the Republican Party pushing back against those trends; the gravitational pull of our binary politics is too strong.

If you have nothing to hide and you trust your government, what can you possibly have to fear? Except that one can just as readily ask: If you have nothing to hide, what do you really have, aside from the panoptic attention of a state, which itself keeps secrets?

Is individual privacy and state privacy the same thing?

In the short term, the span of a lifetime, many of us would argue for privacy, and therefore against transparency.

But history, the long term, is transparency; it is the absence of secrets.

The past, our own past, which our descendants will see us as having emerged from, will not be the past from which we now see ourselves emerging, but a reinterpretation of it, based on subsequently available information, greater transparency and fewer secrets.

our species is the poorer for every secret faithfully kept. Any permanently unbreakable encryption seems counter to that.

So perhaps that desire is as much a part of us, as a species, as our need to build these memory palaces.

the rest comes from his multiple real world examples illustrating exactly why even the most reluctant mathophobe is well advised to achieve a personal understanding of the statistical underpinnings of life, whether that individual is watching football on the couch, picking a school for the children or jiggling anxiously in a hospital admitting office.

And while we’re talking about bias, let’s not forget publication bias: studies that show a drug works get published, but those showing a drug does nothing tend to disappear.

The same trade-off applies to the interpretation of medical tests. Unproven disease screens are likely to do little but feed lots of costly, anxiety-producing garbage into your medical record.

Worse still, the laws of physics themselves seem to be working against us. Ours isn’t just a randomly hostile universe, it's an actively hostile universe

The history of physics, in fact, is a marvel of using simple symmetry principles to construct complicated laws of the universe

if the entire universe were made symmetric, then all of the good features (e.g., you) are decidedly asymmetric lumps that ruin the otherwise perfect beauty of the cosmo

it would be a mistake to be comforted by the symmetries of the universe. In truth, they are your worst enemies. Everything we know about those rational, predictable arrangements dictates that you shouldn't be here at all.

How hostile is the universe to your fundamental existence? Very. Even the simplest assumptions about our place in the universe seem to lead inexorably to devastating results

The symmetry of the universe would bake us in no time at all, but an asymmetry rescues us

In literally every experiment and observation that we’ve ever done, matter and antimatter get created (or annihilated) in perfect concert. That is, every experiment except for one: us.

Matter and antimatter should have completely annihilated one another in the first nanoseconds after the Big Bang. You should not even exist. But you do, and there’s lots more matter where you came from.

if the perfect symmetry between matter and antimatter remained perfect, you wouldn’t be here to think about it.

The flow of time (as near as we can tell) is completely arbitrary. Does entropy increase with time or does it make time? Are our memories the thing that ultimately breaks the symmetry of time?

It seems only a matter of luck (and some fairly arbitrary-looking math) that a symmetric universe would end up being remotely hospitable to complex creatures like us

Without electrons binding to protons, there would be no chemistry, no molecules, and nothing more complicated than a cloud of charged gas. And you’re not a sentient cloud of gas, are you?

A new study out of Germany has found that people are much more confident in the claims of a popular science article then they are in the claims of an academic article written for experts

It was also found that the subjects were more confident in their own judgments after reading a popular article, and that this was tied to a lessened desire to seek out more information from expert sources.

"easiness effect”

the issue arises from the manner in which popular science is presented; as opposed to how scientists themselves present data to each other and to the public.

This emboldens people to reject the ideas of experts who they see as superfluous to their understanding of an idea (which they have already grasped).

materialism is not the greedy desire for material goods, but rather the belief that the fundamental reality of the world is material;

idealism is not the aspiration toward lofty and laudable goals, but rather the belief that the fundamental reality of the world is mental or idea-like. English-speaking philosophers today tend to speak of “physicalism” or “naturalism” rather than materialism (perhaps to avoid confusion with the Wall Street sense of the term). At the same time, Anglo-American historians of philosophy continue to find the distinction between materialism and idealism a useful one in our attempts at categorizing past schools of thought. Democritus and La Mettrie were materialists; Hobbes was pretty close. Berkeley and Kant were idealists; Leibniz may have been.

And it was these paradoxes that led the Irish philosopher to conclude that talk of matter was but a case of multiplying entities beyond necessity. For Berkeley, all we can know are ideas, and for this reason it made sense to suppose that the world itself consists in ideas.

Soviet and Western Marxists alike, by stark contrast, and before them the French “vulgar” (i.e., non-dialectical) materialists of the 18th century, saw and see the material world as the base and cause of all mental activity, as both bringing ideas into existence, and also determining the form and character of a society’s ideas in accordance with the state of its technology, its methods of resource extraction and its organization of labor. So here to focus on the material is not to become distracted from the true source of being, but rather to zero right in on it.

one great problem with the concept of materialism is that it says very little in itself. What is required in addition is an elaboration of what a given thinker takes matter, or ideas, to be. It may not be just the Marxist aftertaste, but also the fact that the old common-sense idea about matter as brute, given stuff has turned out to have so little to do with the way the physical world actually is, that has led Anglo-American philosophers to prefer to associate themselves with the “physical” or the “natural” rather than with the material.  Reality, they want to say, is just what is natural, while everything else is in turn “supernatural” (this distinction has its clarity going for it, but it also seems uncomfortably close to tautology). Not every philosopher has a solid grasp of subatomic physics, but most know enough to grasp that, even if reality is eventually exhaustively accounted for through an enumeration of the kinds of particles and a few basic forces, this reality will still look nothing like what your average person-in-the-street takes reality to be.

The 18th-century idealist philosopher George Berkeley strongly believed that matter was only a fiction contrived by philosophers in the first place, for which the real people had no need. For Berkeley, there was never anything common-sensical about matter. We did not need to arrive at the era of atom-splitting and wave-particle duality, then, in order for the paradoxes inherent in matter to make themselves known (is it infinitely divisible or isn’t it?

Central to this performance was the concept of  “materialism.” The entire history of philosophy, in fact, was portrayed in Soviet historiography as a series of matches between the materialist home-team and its “idealist” opponents, beginning roughly with Democritus (good) and Plato (bad), and culminating in the opposition between official party philosophy and logical positivism, the latter of which was portrayed as a shrouded variety of idealism. Thus from the “Short Philosophical Dictionary,” published in Moscow in 1951, we learn that the school of logical empiricism represented by Rudolf Carnap, Otto Neurath and others, “is a form of subjective idealism, characteristic of degenerating bourgeois philosophy in the epoch of the decline of capitalism.”Now the Soviet usage of this pair of terms appears to fly in the face of our ordinary, non-philosophical understanding of them (that, for example,  Wall Street values are “materialist,” while the Occupy movement is “idealist”). One might have thought that the communists should be flinging the “materialist” label at their capitalist enemies, rather than claiming it for themselves. One might also have thought that the Bolshevik Revolution and the subsequent failed project of building a workers’ utopia was nothing if not idealistic.

Consider money. Though it might sometimes be represented by bank notes or coins, money is an immaterial thing par excellence, and to seek to acquire it is to move on the plane of ideas. Of course, money can also be converted into material things, yet it seems simplistic to suppose that we want money only in order to convert it into the material things we really want, since even these material things aren’t just material either: they are symbolically dense artifacts, and they convey to others certain ideas about their owners. This, principally, is why their owners want them, which is to say that materialists (in the everyday sense) are trading in ideas just as much as anyone else.

In the end no one really cares about stuff itself. Material acquisitions — even, or perhaps especially, material acquisitions of things like Rolls Royces and Rolexes — are maneuvers within a universe of materially instantiated ideas. This is human reality, and it is within this reality that mystics, scientists, and philosophers alike are constrained to pursue their various ends, no matter what they might take the ultimate nature of the external world to be.

Using the traditional privacy idea that once something's public, it is public for any purpose, you're lead down a very narrow path of reasoning about this app's appropriateness and what the services it was built on could do about it.

using Nissenbaum's theory, the bad feelings that people have around the app make sense: People gave data to Foursquare or Facebook in one context and then it showed up in another context that they weren't expecting.

My education taught me to believe that people who didn’t go to an Ivy League or equivalent school weren’t worth talking to, regardless of their class. I was given the unmistakable message that such people were beneath me.

The existence of multiple forms of intelligence has become a commonplace, but however much elite universities like to sprinkle their incoming classes with a few actors or violinists, they select for and develop one form of intelligence: the analytic.

Students at places like Cleveland State, unlike those at places like Yale, don’t have a platoon of advisers and tutors and deans to write out excuses for late work, give them extra help when they need it, pick them up when they fall down.

When people say that students at elite schools have a strong sense of entitlement, they mean that those students think they deserve more than other people because their SAT scores are higher.

The political implications should be clear. As John Ruskin told an older elite, grabbing what you can get isn’t any less wicked when you grab it with the power of your brains than with the power of your fists.

students at places like Yale get an endless string of second chances. Not so at places like Cleveland State.

The second disadvantage, implicit in what I’ve been saying, is that an elite education inculcates a false sense of self-worth. Getting to an elite college, being at an elite college, and going on from an elite college—all involve numerical rankings: SAT, GPA, GRE. You learn to think of yourself in terms of those numbers. They come to signify not only your fate, but your identity; not only your identity, but your value.

For the elite, there’s always another extension—a bailout, a pardon, a stint in rehab—always plenty of contacts and special stipends—the country club, the conference, the year-end bonus, the dividend.

In short, the way students are treated in college trains them for the social position they will occupy once they get out. At schools like Cleveland State, they’re being trained for positions somewhere in the middle of the class system, in the depths of one bureaucracy or another. They’re being conditioned for lives with few second chances, no extensions, little support, narrow opportunity—lives of subordination, supervision, and control, lives of deadlines, not guidelines. At places like Yale, of course, it’s the reverse.

Elite schools nurture excellence, but they also nurture what a former Yale graduate student I know calls “entitled mediocrity.”

An elite education gives you the chance to be rich—which is, after all, what we’re talking about—but it takes away the chance not to be. Yet the opportunity not to be rich is one of the greatest opportunities with which young Americans have been blessed. We live in a society that is itself so wealthy that it can afford to provide a decent living to whole classes of people who in other countries exist (or in earlier times existed) on the brink of poverty or, at least, of indignity. You can live comfortably in the United States as a schoolteacher, or a community organizer, or a civil rights lawyer, or an artist

The liberal arts university is becoming the corporate university, its center of gravity shifting to technical fields where scholarly expertise can be parlayed into lucrative business opportunities.

You have to live in an ordinary house instead of an apartment in Manhattan or a mansion in L.A.; you have to drive a Honda instead of a BMW or a Hummer; you have to vacation in Florida instead of Barbados or Paris, but what are such losses when set against the opportunity to do work you believe in, work you’re suited for, work you love, every day of your life? Yet it is precisely that opportunity that an elite education takes away. How can I be a schoolteacher—wouldn’t that be a waste of my expensive education?

Isn’t it beneath me? So a whole universe of possibility closes, and you miss your true calling.

This is not to say that students from elite colleges never pursue a riskier or less lucrative course after graduation, but even when they do, they tend to give up more quickly than others.

But if you’re afraid to fail, you’re afraid to take risks, which begins to explain the final and most damning disadvantage of an elite education: that it is profoundly anti-intellectual.

being an intellectual is not the same as being smart. Being an intellectual means more than doing your homework.

The system forgot to teach them, along the way to the prestige admissions and the lucrative jobs, that the most important achievements can’t be measured by a letter or a number or a name. It forgot that the true purpose of education is to make minds, not careers.

Being an intellectual means, first of all, being passionate about ideas—and not just for the duration of a semester, for the sake of pleasing the teacher, or for getting a good grade.

Only a small minority have seen their education as part of a larger intellectual journey, have approached the work of the mind with a pilgrim soul. These few have tended to feel like freaks, not least because they get so little support from the university itself. Places like Yale, as one of them put it to me, are not conducive to searchers. GA_googleFillSlot('Rectangle_InArticle_Right'); GA_googleCreateDomIframe("google_ads_div_Rectangle_InArticle_Right_ad_container" ,"Rectangle_InArticle_Right"); Places like Yale are simply not set up to help students ask the big questions

Professors at top research institutions are valued exclusively for the quality of their scholarly work; time spent on teaching is time lost. If students want a conversion experience, they’re better off at a liberal arts college.

When elite universities boast that they teach their students how to think, they mean that they teach them the analytic and rhetorical skills necessary for success in law or medicine or science or business.

Although the notion of breadth is implicit in the very idea of a liberal arts education, the admissions process increasingly selects for kids who have already begun to think of themselves in specialized terms—the junior journalist, the budding astronomer, the language prodigy. We are slouching, even at elite schools, toward a glorified form of vocational training.

There’s a reason elite schools speak of training leaders, not thinkers—holders of power, not its critics. An independent mind is independent of all allegiances, and elite schools, which get a large percentage of their budget from alumni giving, are strongly invested in fostering institutional loyalty.

At a school like Yale, students who come to class and work hard expect nothing less than an A-. And most of the time, they get it.

Yet there is a dimension of the intellectual life that lies above the passion for ideas, though so thoroughly has our culture been sanitized of it that it is hardly surprising if it was beyond the reach of even my most alert students. Since the idea of the intellectual emerged in the 18th century, it has had, at its core, a commitment to social transformation. Being an intellectual means thinking your way toward a vision of the good society and then trying to realize that vision by speaking truth to power.

It takes more than just intellect; it takes imagination and courage.

Being an intellectual begins with thinking your way outside of your assumptions and the system that enforces them. But students who get into elite schools are precisely the ones who have best learned to work within the system, so it’s almost impossible for them to see outside it, to see that it’s even there.

Paradoxically, the situation may be better at second-tier schools and, in particular, again, at liberal arts colleges than at the most prestigious universities. Some students end up at second-tier schools because they’re exactly like students at Harvard or Yale, only less gifted or driven. But others end up there because they have a more independent spirit. They didn’t get straight A’s because they couldn’t be bothered to give everything in every class. They concentrated on the ones that meant the most to them or on a single strong extracurricular passion or on projects that had nothing to do with school

I’ve been struck, during my time at Yale, by how similar everyone looks. You hardly see any hippies or punks or art-school types, and at a college that was known in the ’80s as the Gay Ivy, few out lesbians and no gender queers. The geeks don’t look all that geeky; the fashionable kids go in for understated elegance. Thirty-two flavors, all of them vanilla.

The most elite schools have become places of a narrow and suffocating normalcy. Everyone feels pressure to maintain the kind of appearance—and affect—that go with achievement

Now that students are in constant electronic contact, they never have trouble finding each other. But it’s not as if their compulsive sociability is enabling them to develop deep friendships.

What happens when busyness and sociability leave no room for solitude? The ability to engage in introspection, I put it to my students that day, is the essential precondition for living an intellectual life, and the essential precondition for introspection is solitude

the life of the mind is lived one mind at a time: one solitary, skeptical, resistant mind at a time. The best place to cultivate it is not within an educational system whose real purpose is to reproduce the class system.

She became a science journalist. At first it was a lark, a way to get free press passes to conferences where she and her father could ask questions of the greatest minds in quantum mechanics, string theory and cosmology. But within a short time, as she started getting assignments, journalism became a calling, and an identity.

“If observers create reality, where do the observers come from?” But the great man responded in riddles. “The universe is a self-­excited circuit,” Wheeler said. “The boundary of a boundary is zero.” The unraveling of these mysteries propels the next 400 or so pages.

she has an epiphany — that for something to be real, it must be invariant — she flies home to share it with her father. They discuss her insight over breakfast at a neighborhood haunt, where they make a list on what they will affectionately call “the IHOP napkin.” They list all the possible “ingredients of ultimate reality,” planning to test each item for whether it is “real,” that is whether it is invariant and can exist in the absence of an observer.

their readings and interviews reveal that each item in turn is observer-dependent. Space? Observer-dependent, and therefore not real. Gravity, electromagnetism, angular momentum? No, no, and no. In the end, every putative “ingredient of ultimate reality” is eliminated, including one they hadn’t even bothered to put on the list because it seemed weird to: reality itself

What remained was an unsettling and essential insight: that “physics isn’t the machinery behind the workings of the world; physics is the machinery behind the illusion that there is a world.”

In the proposal, she clarifies how cosmology and quantum mechanics have evolved as scientists come to grips with the fact that things they had taken to be real — quantum particles, space-time, gravity, dimension — turn out to be ­observer-dependent.
