“Facts are facts and will not disappear on account of your likes”*…

… That said, some facts may morph out from under us. In consideration of “in-between” facts:

When people think of knowledge, they generally think of two sorts of facts: facts that don’t change, like the height of Mount Everest or the capital of the United States, and facts that fluctuate constantly, like the temperature or the stock market close.

But in between there is a third kind: facts that change slowly. These are facts which we tend to view as fixed, but which shift over the course of a lifetime. For example: What is Earth’s population? I remember learning 6 billion, and some of you might even have learned 5 billion. Well, it turns out it’s about 6.8 billion.

Or, imagine you are considering relocating to another city. Not recognizing the slow change in the economic fortunes of various metropolitan areas, you immediately dismiss certain cities. For example, Pittsburgh, a city in the core of the historic Rust Belt of the United States, was for a long time considered to be something of a city to avoid. But recently, its economic fortunes have changed, swapping steel mills for technology, with its job growth ranked sixth in the entire United States.

These slow-changing facts are what I term “mesofacts.” Mesofacts are the facts that change neither too quickly nor too slowly, that lie in this difficult-to-comprehend middle, or meso-, scale. Often, we learn these in school when young and hold onto them, even after they change. For example, if, as a baby boomer, you learned high school chemistry in 1970, and then, as we all are apt to do, did not take care to brush up on your chemistry periodically, you would not realize that there are 12 new elements in the Periodic Table. Over a tenth of the elements have been discovered since you graduated high school! While this might not affect your daily life, it is astonishing and a bit humbling.

For these kinds of facts, the analogy of how to boil a frog is apt: Change the temperature quickly, and the frog jumps out of the pot. But slowly increase the temperature, and the frog doesn’t realize that things are getting warmer, until it’s been boiled. So, too, is it with humans and how we process information. We recognize rapid change, whether it’s as simple as a fast-moving object or living with the knowledge that humans have walked on the moon. But anything short of large-scale rapid change is often ignored. This is the reason we continue to write the wrong year during the first days of January.

Our schools are biased against mesofacts. The arc of our educational system is to be treated as little generalists when children, absorbing bits of knowledge about everything from biology to social studies to geology. But then, as we grow older, we are encouraged to specialize. This might have been useful in decades past, but in our increasingly fast-paced and interdisciplinary world, lacking an even approximate knowledge of our surroundings is unwise.

Updating your mesofacts can change how you think about the world. Do you know the percentage of people in the world who use mobile phones? In 1997, the answer was 4 percent. By 2007, it was nearly 50 percent. The fraction of people who are mobile phone users is the kind of fact you might read in a magazine and quote at a cocktail party. But years later the number you would be quoting would not just be inaccurate, it would be seriously wrong. The difference between a tiny fraction of the world and half the globe is startling, and completely changes our view on global interconnectivity.

Mesofacts can also be fun. Let’s focus for a moment on some mesofacts that can be of vital importance if you’re a child, or parent of a child: those about dinosaurs. Just a few decades ago, dinosaurs were thought to be cold-blooded, slow-witted lizards that walked with their legs splayed out beside them. Now, scientists think that many dinosaurs were warm-blooded and fast-moving creatures. And they even had feathers! Just a few weeks ago we learned about the color patterns of dinosaurs (stripes! with orange tufts!). These facts might not affect how you live your life, but then again, you’re probably not 6 years old. There is another mesofact that is unlikely to affect your daily routine, but might win you a bar bet: the number of planets known outside the solar system. After the first extrasolar planet around an ordinary star made headlines back in 1995, most people stopped paying attention. Well, the number of extrasolar planets is currently over 400. Know this, and the next round won’t be on you.

The fact that the world changes rapidly is exciting, but everyone knows about that. There is much change that is neither fast nor momentous, but no less breathtaking.

Introducing the mesofact: “Warning- Your reality is out of date,” from Samuel Arbesman (@arbesman) who went on to develop this notion in a wonderful book, The Half-Life of Facts. Via @inevernu who notes that the above article, which ran in 2010, contains examples of mesofacts that have already changed again– illustrating Arbesman’s point…

As we noodle on knowledge, we might recall that it was on this date in 1642 that the first American college commencement ceremony was held at Harvard College. It was North America’s first taste of non-religious ritual– and was designed to send a clear message to England that its American colonies were a going concern. Still, of the nine seniors graduated, three soon crossed the Atlantic the other way, one to serve as a diplomat for the rebellious Oliver Cromwell and another to study medicine in Italy.

Apropos the piece above, the curriculum followed by those graduates was rather different– was filled with different facts– than those of classes in later centuries.

“Wonder is the beginning of wisdom”*…

An argument for curiosity, openness, and the humility that underlies them both…

Philosophers aren’t the only ones who love wisdom. Everyone, philosopher or not, loves her own wisdom: the wisdom she has or takes herself to have. What distinguishes the philosopher is loving the wisdom she doesn’t have. Philosophy is, therefore, a form of humility: being aware that you lack what is of supreme importance. There may be no human being who exemplified this form of humility more perfectly than Socrates. It is no coincidence that he is considered the first philosopher within the Western canon.

Socrates did not write philosophy; he simply went around talking to people. But these conversations were so transformative that Plato devoted his life to writing dialogues that represent Socrates in conversation. These dialogues are not transcripts of actual conversations, but they are nonetheless clearly intended to reflect not only Socrates’s ideas but his personality. Plato wanted the world to remember Socrates. Generations after Socrates’s death, warring philosophical schools such as the Stoics and the Skeptics each appropriated Socrates as figurehead. Though they disagreed on just about every point of doctrine, they were clear that in order to count themselves as philosophers they had to somehow be working in the tradition of Socrates.

What is it about Socrates that made him into a symbol for the whole institution of philosophy? Consider the fact that, when the Oracle at Delphi proclaims Socrates wisest of men, he tries to prove it wrong. As Plato recounts it in the Apology:

I went to one of those reputed wise, thinking that there, if anywhere, I could refute the oracle and say to it: “This man is wiser than I, but you said I was.” Then, when I examined this man—there is no need for me to tell you his name, he was one of our public men—my experience was something like this: I thought that he appeared wise to many people and especially to himself, but he was not. I then tried to show him that he thought himself wise, but that he was not. As a result he came to dislike me, and so did many of the bystanders. So I withdrew and thought to myself: “I am wiser than this man; it is likely that neither of us knows anything worthwhile, but he thinks he knows something when he does not, whereas when I do not know, neither do I think I know; so I am likely to be wiser than he to this small extent, that I do not think I know what I do not know.”

If Socrates’s trademark claim is this protestation of ignorance, his trademark activity is the one also described in this passage: refuting the views of others. These are the conversations we find in Plato’s texts. How are the claim and the activity related? Socrates denies that his motivations are altruistic: he says he is not a teacher, and insists that he is himself the primary beneficiary of the conversations he initiates. This adds to the mystery: What is Socrates getting out of showing people that they don’t know what they take themselves to know? What’s his angle?

Over and over again, Socrates approaches people who are remarkable for their lack of humility—which is to say, for the fact that they feel confident in their own knowledge of what is just, or pious, or brave, or moderate. You might have supposed that Socrates, whose claim to fame is his awareness of his own ignorance, would treat these self-proclaimed “wise men” (Sophists) with contempt, hostility, or indifference. But he doesn’t. The most remarkable feature of Socrates’s approach is his punctilious politeness and sincere enthusiasm. The conversation usually begins with Socrates asking his interlocutor: Since you think you know, can you tell me, what is courage (or wisdom, or piety, or justice . . .)? Over and over again, it turns out that they think they can answer, but they can’t. Socrates’s hope springs eternal: even as he walks toward the courtroom to be tried—and eventually put to death—for his philosophical activity, he is delighted to encounter the self-important priest Euthyphro, who will, surely, be able to say what piety is…

Socrates seemed to think that the people around him could help him acquire the knowledge he so desperately wanted—even though they were handicapped by the illusion that they already knew it. Indeed, I believe that their ill-grounded confidence was precisely what drew Socrates to them. If you think you know something, you will be ready to speak on the topic in question. You will hold forth, spout theories, make claims—and all this, under Socrates’s relentless questioning, is the way to actually acquire the knowledge you had deluded yourself into thinking you already had…

It’s one thing to say, “I don’t know anything.” That thought comes cheap. One can wonder, “Who really and truly knows anything?” in a way that is dismissive, uninquisitive, detached. It can be a way of saying, “Knowledge is unattainable, so why even try?” Socratic humility is more expensive and more committal than that. He sought to map the terrain of his ignorance, to plot its mountains and its rivers, to learn to navigate it. That, I think, is why he speaks of knowledge of his own ignorance. He’s not just someone who acknowledges or admits to his ignorance, but someone who has learned to dwell within it.

Admittedly, this may seem like a paradoxical project. It’s one thing to be missing your wallet—you will know it once you’ve found it. But suppose you’re missing not only your wallet, but also the knowledge that you ever had a wallet, and the understanding of what a wallet is. One of Socrates’s interlocutors, Meno, doubts whether it’s possible to come to know anything if you know so little to begin with. If someone doesn’t know where she’s going, it doesn’t seem as though she can even take a first step in the right direction. Can you map in total darkness?

Socrates’s answer was no. Or at least: you can’t do it alone. The right response to noticing one’s own ignorance is to try to escape it by acquiring someone else’s knowledge. But the only way to do that is to explain to them why you aren’t yet able to accept this or that claim of theirs as knowledge—and that is what mapping one’s ignorance amounts to. Socrates stages an exhibition of this method for Meno by demonstrating how much geometrical progress he can make with a young slave boy by doing nothing but asking questions that expose the boy’s false assumptions. It is when he refutes others’ claims to knowledge that Socrates’s own ignorance takes shape, for him, as something he can know. What appears as a sea of darkness when approached introspectively turns out to be navigable when brought into contact with the knowledge claims of another…

Socrates saw the pursuit of knowledge as a collaborative project involving two very different roles. There’s you or I or some other representative of Most People, who comes forward and makes a bold claim. Then there’s Socrates, or one of his contemporary descendants, who questions and interrogates and distinguishes and calls for clarification. This is something we’re often still doing—as philosophers, as scientists, as interviewers, as friends, on Twitter and Facebook and in many casual personal conversations. We’re constantly probing one another, asking, “How can you say that, given X, Y, Z?” We’re still trying to understand one another by way of objection, clarification, and the simple fact of inability to take what someone has said as knowledge. It comes so naturally to us to organize ourselves into the knower/objector pairing that we don’t even notice we are living in the world that Socrates made. The scope of his influence is remarkable. But equally remarkable is the means by which it was achieved: he did so much by knowing, writing, and accomplishing—nothing at all.

And yet for all this influence, many of our ways are becoming far from Socratic. More and more our politics are marked by unilateral persuasion instead of collaborative inquiry. If, like Socrates, you view knowledge as an essentially collaborative project, you don’t go into a conversation expecting to persuade any more than you expect to be persuaded. By contrast, if you do assume you know, you embrace the role of persuader in advance, and stand ready to argue people into agreement. If argument fails, you might tolerate a state of disagreement—but if the matter is serious enough, you’ll resort to enforcing your view through incentives or punishments. Socrates’s method eschewed the pressure to persuade. At the same time, he did not tolerate tolerance. His politics of humility involved genuinely opening up the question under dispute, in such a way that neither party would be permitted to close it, to settle on an answer, unless the other answered the same. By contrast, our politics—of persuasion, tolerance, incentives, and punishment—is deeply uninquisitive…

Knowing takes radical collaboration: an openness to being persuaded as much as an eagerness to persuade: “Against Persuasion,” from Agnes Callard (@AgnesCallard)

As we listen and learn, we might recall that it was on this date in 1966 that the Eleventh Plenum of the Eighth Central Committee of the Chinese Communist Party was hastily convened to advance Mao Zedong’s by then decidedly radical agenda for China– teeing up “Red August,” a series of purges of reactionary or otherwise impure thinkers. According to official statistics published in 1980, from August to September in 1966, a total of 1,772 people—including teachers and principals of many schools—were killed in Beijing by Red Guards; 33,695 homes were ransacked and 85,196 families were forced to leave the city. (1985 statistics, which included the areas immediately around Beijing, put the death toll at around 10,000.)

Red August kicked off the Great Proletarian Cultural Revolution, or as we tend to know it, The Cultural Revolution, which lasted until Mao’s death in 1976. Its stated goal was to preserve Chinese communism by purging alternative thought– remnants of capitalist and traditional elements– from Chinese society, and to impose Mao Zedong Thought (known outside China as Maoism) as the dominant ideology in the PRC. A selection of Mao’s sayings, compiled in Little Red Book, became a sacred text in what was, essentially a personality cult.

Estimates of the death toll from the Cultural Revolution, including civilians and Red Guards, vary greatly, ranging from hundreds of thousands to to 20 million. The exact figure of those who were persecuted or died during the Cultural Revolution, however, may never be known, as many deaths went unreported or were actively covered up by the police or local authorities. Tens of millions of people were persecuted (especially members of ethnic minorities): senior officials were purged or exiled; millions were accused of being members of the Five Black Categories, suffering public humiliation, imprisonment, torture, hard labor, seizure of property, and sometimes execution or harassment into suicide; intellectuals were considered the “Stinking Old Ninth” and were widely persecuted—notable scholars and scientists were killed or committed suicide. Schools and universities were closed. And over 10 million urban “intellectual youths“ were sent to rural areas in the Down to the Countryside Movement.

“Doing research on the Web is like using a library assembled piecemeal by pack rats and vandalized nightly”*…

But surely, argues Jonathan Zittrain, it shouldn’t be that way…

Sixty years ago the futurist Arthur C. Clarke observed that any sufficiently advanced technology is indistinguishable from magic. The internet—how we both communicate with one another and together preserve the intellectual products of human civilization—fits Clarke’s observation well. In Steve Jobs’s words, “it just works,” as readily as clicking, tapping, or speaking. And every bit as much aligned with the vicissitudes of magic, when the internet doesn’t work, the reasons are typically so arcane that explanations for it are about as useful as trying to pick apart a failed spell.

Underpinning our vast and simple-seeming digital networks are technologies that, if they hadn’t already been invented, probably wouldn’t unfold the same way again. They are artifacts of a very particular circumstance, and it’s unlikely that in an alternate timeline they would have been designed the same way.

The internet’s distinct architecture arose from a distinct constraint and a distinct freedom: First, its academically minded designers didn’t have or expect to raise massive amounts of capital to build the network; and second, they didn’t want or expect to make money from their invention.

The internet’s framers thus had no money to simply roll out a uniform centralized network the way that, for example, FedEx metabolized a capital outlay of tens of millions of dollars to deploy liveried planes, trucks, people, and drop-off boxes, creating a single point-to-point delivery system. Instead, they settled on the equivalent of rules for how to bolt existing networks together.

Rather than a single centralized network modeled after the legacy telephone system, operated by a government or a few massive utilities, the internet was designed to allow any device anywhere to interoperate with any other device, allowing any provider able to bring whatever networking capacity it had to the growing party. And because the network’s creators did not mean to monetize, much less monopolize, any of it, the key was for desirable content to be provided naturally by the network’s users, some of whom would act as content producers or hosts, setting up watering holes for others to frequent.

Unlike the briefly ascendant proprietary networks such as CompuServe, AOL, and Prodigy, content and network would be separated. Indeed, the internet had and has no main menu, no CEO, no public stock offering, no formal organization at all. There are only engineers who meet every so often to refine its suggested communications protocols that hardware and software makers, and network builders, are then free to take up as they please.

So the internet was a recipe for mortar, with an invitation for anyone, and everyone, to bring their own bricks. Tim Berners-Lee took up the invite and invented the protocols for the World Wide Web, an application to run on the internet. If your computer spoke “web” by running a browser, then it could speak with servers that also spoke web, naturally enough known as websites. Pages on sites could contain links to all sorts of things that would, by definition, be but a click away, and might in practice be found at servers anywhere else in the world, hosted by people or organizations not only not affiliated with the linking webpage, but entirely unaware of its existence. And webpages themselves might be assembled from multiple sources before they displayed as a single unit, facilitating the rise of ad networks that could be called on by websites to insert surveillance beacons and ads on the fly, as pages were pulled together at the moment someone sought to view them.

And like the internet’s own designers, Berners-Lee gave away his protocols to the world for free—enabling a design that omitted any form of centralized management or control, since there was no usage to track by a World Wide Web, Inc., for the purposes of billing. The web, like the internet, is a collective hallucination, a set of independent efforts united by common technological protocols to appear as a seamless, magical whole.

This absence of central control, or even easy central monitoring, has long been celebrated as an instrument of grassroots democracy and freedom. It’s not trivial to censor a network as organic and decentralized as the internet. But more recently, these features have been understood to facilitate vectors for individual harassment and societal destabilization, with no easy gating points through which to remove or label malicious work not under the umbrellas of the major social-media platforms, or to quickly identify their sources. While both assessments have power to them, they each gloss over a key feature of the distributed web and internet: Their designs naturally create gaps of responsibility for maintaining valuable content that others rely on. Links work seamlessly until they don’t. And as tangible counterparts to online work fade, these gaps represent actual holes in humanity’s knowledge…

The glue that holds humanity’s knowledge together is coming undone: “The Internet Is Rotting.” @zittrain explains what we can do to heal it.

As we protect our past for the future, we might recall that it was on this date in 1937 that Hormel introduced Spam. It was the company’s attempt to increase sales of pork shoulder, not at the time a very popular cut. While there are numerous speculations as to the “meaning of the name” (from a contraction of “spiced ham” to “Scientifically Processed Animal Matter”), its true genesis is known to only a small circle of former Hormel Foods executives.

As a result of the difficulty of delivering fresh meat to the front during World War II, Spam became a ubiquitous part of the U.S. soldier’s diet. It became variously referred to as “ham that didn’t pass its physical,” “meatloaf without basic training,” and “Special Army Meat.” Over 150 million pounds of Spam were purchased by the military before the war’s end. During the war and the occupations that followed, Spam was introduced into Guam, Hawaii, Okinawa, the Philippines, and other islands in the Pacific. Immediately absorbed into native diets, it has become a unique part of the history and effects of U.S. influence in the Pacific islands.

“Do not explain your philosophy. Embody it.”*…

Truth, knowledge, justice – to understand how our loftiest abstractions earn their keep, trace them to their practical origins…

Unlike ideas of air, food and water that allow us to think about the everyday resources we need to survive, the venerable notions of knowledge, truth or justice don’t obviously cater to practical needs. On the contrary, these exalted ideals draw our gaze away from practical pursuits. They are imbued with grandeur precisely because of their superb indifference to mundane human concerns. Having knowledge is practically useful, but why would we also need the concept of knowledge? The dog who knows where his food is seems fine without the concept of knowledge, so long as he’s not called upon to give a commencement address. And yet the concepts of knowledge, truth or justice appear to have been important enough to emerge across different cultures and endure over the ages. Why, then, did we ever come to think in these terms?

Friedrich Nietzsche grumbled that, when it came to identifying the origins of lofty ideas, philosophers had a tendency to be led astray by their own respect for them. In dealing with what they felt were the ‘highest concepts’, the ‘last wisps of smoke from the evaporating end of reality’, they had reverently placed them ‘at the beginning as the beginning’, convinced that the higher could never have grown out of the lower: Plato’s eternal Forms, the mind of God, Immanuel Kant’s noumenal world – they had all served as cradles to higher concepts, offering them a suitably distinguished pedigree.

But to insist that higher concepts were bound to have higher origins, Nietzsche thought, was to let one’s respect for those ideas get in the way of a truthful understanding of them. If, after the ‘Death of God’ and the advent of Darwinism, we were successfully to ‘translate humanity back into nature’, as Nietzsche’s felicitous rallying cry had it, we needed to trace seemingly transcendent ideas such as knowledge, truth or justice to their roots in human concerns. Their origins weren’t empyrean (to be sought in the highest spheres) but distinctly sublunary (found in lowly practical needs). Nietzsche encouraged us to ask: what necessities might have been the mothers of those inventions? And what, if anything, do they still do for us?…

As we root out first principles, we might spare a thought for Sir Alfred Jules “Freddie” Ayer (usually cited as A.J. Ayer); he died on this date in 1989. A philosopher associated with the the British humanist movement, he is best remembered as the champion of of logical positivism, particularly in his books Language, Truth, and Logic (1936) and The Problem of Knowledge (1956). While he had a number of material disagreements with Nietzsche, Ayer shared his rejection of objective ethical values.

“Trivia is a fact without a home”*…

What makes for a good trivia question? There are some common-sense requirements. It should be clearly written, accurate, and gettable for at least some people. (Acceptable degrees of difficulty vary.) It must be properly “pinned” to its answer, meaning that there are no correct responses other than those the questioner is seeking. (This can be trickier than you might think.) In the opinion of Shayne Bushfield, the creator and sole full-time employee of LearnedLeague, an online trivia community that he has run since 1997, people should recognize the answer to the question as something worth knowing, as having a degree of importance. “Trivia is not the right word for it,” he told me recently. “Because trivia technically means trivial, or not worth knowing, and it’s the opposite.”

The idea that the answers to trivia questions are worth knowing is a matter of some debate, and has been more or less since trivia itself was born. The pop-culture pastime of quizzing one another on a variety of subjects as a kind of game is fundamentally a phenomenon of the past hundred years or so: its first appearance as a fad seems to date to 1927, when “Ask Me Another! The Question Book” was published. As the “Jeopardy!” champion Ken Jennings notes in his book “Brainiac,” “Ask Me Another” was written by “two out-of-work Amherst alumni” living in Manhattan, who “were shocked to find that, despite their fancy new diplomas and broad liberal educations, the job world wasn’t beating a path to their door.” Their book was a hit, and newspapers began running quiz columns, a follow-up of sorts to the national crossword craze of a couple of years before. Quiz shows came to radio and television about a decade later. But none of these games were called trivia until a pair of Columbia undergraduates, in the mid-sixties, shared their version of the game, first in the school’s Daily Spectator and later in their own popular quiz book, which really did prize the trivial: the name of the Lone Ranger’s nephew, the name of the snake that appeared in “We’re No Angels,” and so on. This version of trivia was all about the stuff one had read, listened to, or watched as a kid, and its appeal, according to one of the Columbia pair, was concentrated among “young adults who on the one hand realize they have misspent their youth and yet, on the other hand, do not want to let go of it.” The purpose of playing, he explained, was experiencing the feeling produced when an answer finally came to you, “an effect similar to the one that might be induced by a pacifier.”

Presumably, it has always been satisfying to know things, but the particular pleasure of trivia seems to depend on two relatively recent developments: the constant relaying of new information (i.e., mass media) and the mass production of people who learn a lot of things they don’t really need to know. (College attendance began steadily rising in the nineteen-twenties, before booming after the Second World War.) It is sometimes asked whether the popularity of trivia will diminish in the age of Google and Siri, but those earlier developments have only accelerated, and trivia seems, if anything, more popular than ever. In contrast to the mindless ease of looking up the answer to a question online, there’s a gratifying friction in pulling a nearly forgotten fact from your own very analog brain…

The quietly oppositional delight of knowing things you don’t need to know: “The Pleasures of LearnedLeague and the Spirit of Trivia.”
