Best of Rationality Quotes

Tags like "stupid," "bad at __", "sloppy," and so on, are ways of saying "You're performing badly and I don't know why." Once you move it to "you're performing badly because you have the wrong fingerings," or "you're performing badly because you don't understand what a limit is," it's no longer a vague personal failing but a causal necessity. Anyone who never understood limits will flunk calculus. It's not you, it's the bug.

And here, according to Trout, was the reason human beings could not reject ideas because they were bad: Ideas on Earth were badges of friendship or enmity. Their content did not matter. Friends agreed with friends, in order to express friendliness. Enemies disagreed with enemies, in order to express enmity. The ideas Earthlings held didn’t matter for hundreds of thousands of years, since they couldn’t do much about them anyway. Ideas might as well be badges as anything.

On the error of failing to appreciate your opponents three-dimensionality:

They had cliche answers but only to their self-created straw-men. To exaggerate only slightly, they had never talked to anyone who really believed, and had thought deeply about, views drastically different from their own. As a result, when they heard real arguments instead of caricatures, they had no answers, only amazement that such views could be expressed by someone who had the external characteristics of being a member of the intellectual community, and that such views could be defended with apparent cogency. Never have I been more impressed with the advice I once received: "You cannot be sure that you are right unless you understand the arguments against your views better than your opponents do."

Doctor Slithingly watched the readout on the computer screen and rubbed his hands together. ‘Excellent,’ he muttered, his voice a thin, rasping hiss. ‘Excellent!’ He laughed to himself in a chilling falsetto. ‘Soon my plan will come to fruition. Soon I will destroy them all!’ The room resounded with the sound of his insane giggling. This was the culmination of years of research – years of testing tissue samples and creating unnatural biological hybrids – but now it was over. Now, finally, he would destroy them all – every single type and variation of leukaemia. In doing so, he would render useless the work of thousands of charitable organisations as well as denying medical professionals the world over a source of income. He would prevent the publication of hundreds of inspiring stories of survival and sacrifice which might otherwise have sold millions of copies worldwide. ‘Bwahaha!’ he laughed. ‘So long, you meddling haematological neoplasm, you!’

"...I always rejoice to hear of your being still employ'd in experimental Researches into Nature, and of the Success you meet with. The rapid Progress true Science now makes, occasions my regretting sometimes that I was born so soon. It is impossible to imagine the Height to which may be carried, in a thousand years, the Power of Man over Matter. We may perhaps learn to deprive large Masses of their Gravity, and give them absolute Levity, for the sake of easy Transport. Agriculture may diminish its Labor and double its Produce; all Diseases may by sure means be prevented or cured, not excepting even that of Old Age, and our Lives lengthened at pleasure even beyond the antediluvian Standard.

Once upon a time, there was a man who was riding in a horse drawn carriage and traveling to go take care of some affairs; and in the carriage there was also a very big suitcase. He told the driver to of the carriage to drive non-stop and the horse ran extremely fast.

Along the road, there was an old man who saw them and asked, “Sir, you seem anxious, where do you need to go?”

The man in the carriage then replied in a loud voice, “I need to go to the state of Chu.” The old man heard and laughing he smiled and said, “You are going the wrong way. The state of Chu is in the south, how come you are going to to the north?”

“That’s alright,” The man in the carriage then said, “Can you not see? My horse runs very fast.”

“Your horse is great, but your path is incorrect.”

“It’s no problem, my carriage is new, it was made just last month.”

“Your carriage is brand new, but this is not the road one takes to get to Chu.”

“Old Uncle, you don’t know,” and the man in the carriage pointed to the suitcase in the back and said, “In that suitcase there’s alot of money. No matter how long the road is, I am not afraid.”

“You have lots of money, but do not forget, The direction which you are going is wrong. I can see, you should go back the direction which you came from.”

The man in the carriage heard this and irritated said, “I have already been traveling for ten days, how can you tell me to go back from where I came?” He then pointed at the carriage driver and said, “Take a look, he is very young, and he drives very well, you needn’t worry. Goodbye!”

And then he told the driver to drive forward, and the horse ran even faster.

The person who says, as almost everyone does say, that human life is of infinite value, not to be measured in mere material terms, is talking palpable, if popular, nonsense. If he believed that of his own life, he would never cross the street, save to visit his doctor or to earn money for things necessary to physical survival. He would eat the cheapest, most nutritious food he could find and live in one small room, saving his income for frequent visits to the best possible doctors. He would take no risks, consume no luxuries, and live a long life. If you call it living. If a man really believed that other people's lives were infinitely valuable, he would live like an ascetic, earn as much money as possible, and spend everything not absolutely necessary for survival on CARE packets, research into presently incurable diseases, and similar charities.

In fact, people who talk about the infinite value of human life do not live in either of these ways. They consume far more than they need to support life. They may well have cigarettes in their drawer and a sports car in the garage. They recognize in their actions, if not in their words, that physical survival is only one value, albeit a very important one, among many.

There is something about practical things that knocks us off our philosophical high horses. Perhaps Heraclitus really thought he couldn't step in the same river twice. Perhaps he even received tenure for that contribution to philosophy. But suppose some other ancient had claimed to have as much right as Heraclitus did to an ox Heraclitus had bought, on the grounds that since the animal had changed, it wasn't the same one he had bought and so was up for grabs. Heraclitus would have quickly come up with some ersatz, watered-down version of identity of practical value for dealing with property rights, oxen, lyres, vineyards, and the like. And then he might have wondered if that watered-down vulgar sense of identity might be a considerably more valuable concept than a pure and philosophical sort of identity that nothing has.

A lot of outcomes about which we care deeply are not very predictable. For example, it is not comforting to members of a graduate school admissions committee to know that only 23% of the variance in later faculty ratings of a student can be predicted by a unit weighting of the student's undergraduate GPA, his or her GRE score, and a measure of the student's undergraduate institution selectivity -- but that is opposed to 4% based on those committee members' global ratings of the applicant. We want to predict outcomes important to us. It is only rational to conclude that if one method (a linear model) does not predict well, something else may do better. What is not rational -- in fact, it's irrational -- is to conclude that this "something else" necessarily exists and, in the absence of any positive supporting evidence, is intuitive global judgment.

A few years into this book, I was diagnosed as diabetic and received a questionnaire in the mail. The insurance carrier stated that diabetics often suffer from depression and it was worried about me. One of the questions was “Do you think about death?” Yes, I do. “How often?” the company wanted to know. “Yearly? Monthly? Weekly? Daily?” And if daily, how many times per day? I dutifully wrote in, “About 70 times per day.” The next time I saw my internist, she told me the insurer had recommended psychotherapy for my severe depression. I explained to her why I thought about death all day—merely an occupational hazard—and she suggested getting therapy nonetheless. I thought, fine, it might help with the research.

The therapist found me tragically undepressed, and I asked her if she could help me design a new life that would maximize the few years that I had left. After all, one should have a different life strategy at sixty than at twenty. She asked why I thought I was going to die and why I had such a great fear of death. I said, I am going to die. It’s not a fear; it’s a reality. There must be some behavior that could be contraindicated for a man my age but other normally dangerous behavior that takes advantage of the fact that I am risking fewer years at sixty or sixty-five years of age than I was at twenty or twenty-five (such as crimes that carry a life sentence, crushing at age twenty but less so at age sixty-five). Surely psychology must have something to say on the topic. Turns out, according to my therapist, it does not. There was therapy for those with terminal illness, for the bereaved, for the about-to-be-bereaved, for professionals who dealt with terminal patients, and so on, but there was nothing for people who were simply aware that their life would come to a natural end. It would seem to me that this is a large, untapped market. The therapist advised me not to think about death.

Let me differentiate between scientific method and the neurology of the individual scientist.

The individual scientist seems a different animal entirely. The ones I've met seem as passionate, and hence as egotistic and prejudiced, as painters, ballerinas or even, God save the mark, novelists. My hope lies in the feedback system itself, not in any alleged saintliness of the individuals in the system.

“Stupider” for a time might not have been a real word, but it certainly points where it’s supposed to. The other day my sister used the word “deoffensify”. It’s not a real word, but that didn’t make it any less effective. Communication doesn’t care about the “realness” of language, nor does it often care about the exact dictionary definitions.

The categories and classes we construct are simply the semantic sugar which makes the reality go down easier. They should never get confused for the reality that is, the reality which we perceive but darkly and with biased lenses. The hyper-relativists and subjectivists who are moderately fashionable in some humane studies today are correct to point out that science is a human construction and endeavor. Where they go wrong is that they are often ignorant of the fact that the orderliness of many facets of nature is such that even human ignorance and stupidity can be overcome with adherence to particular methods and institutional checks and balances. The predictive power of modern science, giving rise to modern engineering, is the proof of its validity. No talk or argumentation is needed. Boot up your computer. Drive your car.

Two very different attitudes toward the technical workings of mathematics are found in the literature. Already in 1761, Leonhard Euler complained about isolated results which "are not based on a systematic method" and therefore whose "inner grounds seem to be hidden." Yet in the 20'th Century, writers as diverse in viewpoint as Feller and de Finetti are agreed in considering computation of a result by direct application of the systematic rules of probability theory as dull and unimaginative, and revel in the finding of some isolated clever trick by which one can see the answer to a problem without any calculation.

[...]

Feller's perception was so keen that in virtually every problem he was able to see a clever trick; and then gave only the clever trick. So his readers get the impression that:

  • Probability theory has no systematic methods; it is a collection of isolated, unrelated clever tricks, each of which works on one problem but not on the next one.
  • Feller was possessed of superhuman cleverness.
  • Only a person with such cleverness can hope to find new useful results in probability theory.

Indeed, clever tricks do have an aesthetic quality that we all appreciate at once. But we doubt whether Feller, or anyone else, was able to see those tricks on first looking at the problem. We solve a problem for the first time by that (perhaps dull to some) direct calculation applying our systematic rules. After seeing the solution, we may contemplate it and see a clever trick that would have led us to the answer much more quickly. Then, of course, we have the opportunity for gamesmanship by showing others only the clever trick, scorning to mention the base means by which we first found.

British philosophy is more detailed and piecemeal than that of the Continent; when it allows itself some general principle, it sets to work to prove it inductively by examining its various applications. Thus Hume, after announcing that there is no idea without an antecedent impression, immediately proceeds to consider the following objection: suppose you are seeing two shades of colour which are similar but not identical, and suppose you have never seen a shade of colour intermediate between the two, can you nevertheless imagine such a shade? He does not decide the question, and considers that a decision adverse to his general principle would not be fatal to him, because his principle is not logical but empirical. When--to take a contrast--Leibniz wants to establish his monadology, he argues, roughly, as follows: Whatever is complex must be composed of simple parts; what is simple cannot be extended; therefore everything is composed of parts having no extension. But what is not extended is not matter. Therefore the ultimate constituents of things are not material, and, if not material, then mental. Consequently a table is really a colony of souls.

The difference of method, here, may be characterized as follows: In Locke or Hume, a comparatively modest conclusion is drawn from a broad survey of many facts, whereas in Leibniz a vast edifice of deduction is pyramided upon a pin-point of logical principle. In Leibniz, if the principle is completely true and the deductions are entirely valid, all is well; but the structure is unstable, and the slightest flaw anywhere brings it down in ruins. In Locke or Hume, on the contrary, the base of the pyramid is on the solid ground of observed fact, and the pyramid tapers upward, not downward; consequently the equilibrium is stable, and a flaw here or there can be rectified without total disaster.

...beliefs are like clothes. In a harsh environment, we choose our clothes mainly to be functional, i.e., to keep us safe and comfortable. But when the weather is mild, we choose our clothes mainly for their appearance, i.e., to show our figure, our creativity, and our allegiances. Similarly, when the stakes are high we may mainly want accurate beliefs to help us make good decisions. But when a belief has few direct personal consequences, we in effect mainly care about the image it helps to project.

Another learning which cost me much to recognize, can be stated in four words. The facts are friendly.

It has interested me a great deal that most psychotherapists, especially the psychoanalysts, have steadily refused to make any scientific investigation of their therapy, or to permit others to do this. I can understand this reaction because I have felt it. Especially in our early investigations I can well remember the anxiety of waiting to see how the findings came out. Suppose our hypotheses were disproved! Suppose we were mistaken in our views! Suppose our opinions were not justified! At such times, as I look back, it seems to me that I regarded the facts as potential enemies, as possible bearers of disaster. I have perhaps been slow in coming to realize that the facts are always friendly. Every bit of evidence one can acquire, in any area, leads one that much closer to what is true. And being closer to the truth can never be a harmful or dangerous or unsatisfying thing. So while I still hate to readjust my thinking, still hate to give up old ways of perceiving and conceptualizing, yet at some deeper level I have, to a considerable degree, come to realize that these painful reorganizations are what is known as learning, and that though painful they always lead to a more satisfying because somewhat more accurate way of seeing life. Thus at the present time one of the most enticing areas for thought and speculation is an area where several of my pet ideas have not been upheld by the evidence, I feel if I can only puzzle my way through this problem that I will find a much more satisfying approximation to the truth. I feel sure the facts will be my friends.

Therefore, the first and most important duty of philosophy is to test impressions, choosing between them and only deploying those that have passed the test. You know how, with money--an area where we believe our interest to be at stake--we have developed the art of assaying, and considerable ingenuity has gone into developing a way to test if coins are counterfeit, involving our senses of sight, smell, hearing, and touch. The assayer will let the denarius drop and listen intently to its ring; and he is not satisfied to listen just once: after repeated listenings he practically acquires a musician's subtle ear. It is a measure of the effort we are prepared to expend to guard against deception when accuracy is at a premium.

When it comes to our poor mind, however, we can't be bothered; we are satisfied accepting any and all impressions, because here the loss we suffer is not obvious. If you want to know just how little concerned you are about things good and bad, and how serious about things indifferent, compare your attitude to going blind with your attitude about being mentally in the dark. You will realize, I think, how inappropriate your values really are.

There are big differences between "a study" and "a good study" and "a published study" and "a study that's been independently confirmed" and "a study that's been independently confirmed a dozen times over." These differences are important; when a scientist says something, it's not the same as the Pope saying it. It's only when dozens and hundreds of scientists start saying the same thing that we should start telling people to guzzle red wine out of a fire hose.

How a game theorist buys a car:

"Hello, my name is Bruce Bueno de Mesquita. I plan to buy the following car [list the exact model and features] today at five P.M. I am calling all of the dealerships within a fifty-mile radius of my home and I am telling each of them what I am telling you. I will come in and buy the car today at five P.M. from the dealer who gives me the lowest price. I need to have the all-in price, including taxes, dealer prep [I ask them not to prep the car and not charge me for it, since dealer prep is little more than giving you a washed car with plastic covers and paper floormats removed, usually for hundreds of dollars], everything, because I will make out the check to your dealership before I come and will not have another check with me."

From The Predictioneer's Game, page 7.

Other car-buying tips from Bueno de Mesquita, in case you're about to buy a car:

* Figure out exactly what car you want to buy by searching online before making any contact with dealerships.

* Don't be afraid to purchase a car from a distant dealership--the manufacturer provides the warranty, not the dealer.

* Be sure to tell each dealer you will be sharing the price they quote you with subsequent dealers.

* Don't take shit from dealers who tell you "you can't buy a car over the phone" or do anything other than give you their number. If a dealer is stonewalling, make it quite clear that you're willing to get what you want elsewhere.

* Arrive at the lowest-price dealer just before 5:00 PM to close the deal. In the unlikely event that the dealer changes their terms, go for the next best price.

The Disobedi-Ant

The story of the Disobedi-Ant is very short. It refused to believe that its powerful impulses to play instead of work were anything but unique expressions of its very unique self, and it went its merry way, singing, "What I choose to do has nothing to do with what any-ant else chooses to do! What could be more self-evident?"

Coincidentally enough, so went the reasoning of all its colony-mates. In fact, the same refrain was independently invented by every last ant in the colony, and each ant thought it original. It echoed throughout the colony, even with the same melody.

The colony perished.

Among a great many other things that chess teaches you is to control the initial excitement you feel when you see something that looks good. It trains you to think before grabbing, and to think just as objectively when you're in trouble. When you're making a film you have to make most of your decisions on the run, and there is a tendency to always shoot from the hip. It takes more discipline than you might imagine, to think, even for thirty seconds, in the noisy, confusing, high-pressure atmosphere of a film set. But a few seconds' thought can often prevent a serious mistake being made about something that looks good at first glance. With respect to films, chess is more useful in preventing you from making mistakes than giving you ideas. Ideas come spontaneously and the discipline required to evaluate and put them to use tends to be the real work.

The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation.

So, let's say some bros of mine and I have some hand-signals for, you know, bro stuff. And one of the signals means, "Oh, shit. Here comes that girl! You know. That girl. She's coming." That signal has a particular context. Eventually, one of my bros gets tired of sloppy use of the signal, and sets about laying out specifically what situations make a girl that girl. If I used the signal in a close-but-not-quite context, he'd handle it and then pull me aside and say, "I know she and I had that thing that one time, but we never... well, it wasn't quite THAT. You know? So that signal, it freaked me out, because I thought it had to be someone else. Make sure you're using it properly, okay?" And I'd be like, "Bro. Got it."

Another friend of mine, he recognizes the sorts of situations we use the signal in have a common thread, so he begins using the hand signal for other situations, any situation that has the potential for both danger and excitement. So if someone invites us to this real sketchy bar, he'll give me the signal - "This could be bad. But what if it's not?" And I'd respond, "I see what you did there."

Maybe you see where this is going. We're hanging out one day, and some guy suggests we crash some party. Bro #2 signals, and bro #1 freaks out, looking around. And then he's like, "OH FUCK I HAVE TO CALL HER." And #2 says, "No, dude, there's no one coming. I just meant, this is like one of those situations, you know?" And they're pissed at each other because they're using the same signal to mean different things. I'm not mad, because I generally know what they each mean, but I have more context than they do.

The same thing probably happens with analytics and Continentals.

It is the most common way of trying to cope with novelty: by means of metaphors and analogies we try to link the new to the old, the novel to the familiar. Under sufficiently slow and gradual change, it works reasonably well; in the case of a sharp discontinuity, however, the method breaks down: though we may glorify it with the name 'common sense', our past experience is no longer relevant, the analogies become too shallow, and the metaphors become more misleading than illuminating.

Here is a hand. How do I know? Look closely, asshole, it's clearly a hand.

Look, if you really insist on doubting that here is a hand, or anything else, there's nothing really I can say to convince you otherwise. What the tits would the world even look like if this weren't a hand? What sort of system is your doubt endorsing? After all, you can't just say "It's not true that here is a hand." You have to be endorsing some other picture of the world. [...]

So it turns out when I say things like "Here is a hand" I'm not really making a claim about the world, I'm laying down some rules for discussion. If you doubt there's a hand here, then fuck you and that's all there is to it. We can't really talk about anything now, because we can't even agree on something as simple as a goddamn hand. When we all agree here is a hand, then we can go about discussing our world in meaningful ways. Skepticism just undermines a foundation and replaces it with nothing; it[']s paralyzing. The grounds for such radical skepticism don't exist; it presupposes and relies on the very certainty it tries to undermine.

This is more practical than you realize. There are people who actually believe that the world is only 6,000 years old. What the fuck, right? But if you've ever talked with one of them, you know that they're fucking impossible to have what you consider a 'reasonable' discussion with. It's not like they don't have answers for everything, it[']s just that those answers don't make any fucking sense to you. It[']s the sort of gibberish that makes you want to scream. The problem is that you don't even play the game by the same goddamn rules. You're both certain of your positions, because those positions are logically derived from the worldview each of you endorses as your starting point, and you both look at each other's foundations and say, "Seriously, what the fuck are you talking about?" You don't even know how you would go about convincing them that you're right and they're wrong; you don't even agree on a method by which to do that.

If you flew to some part of the world where they'd never heard of an airplane or even a bird, how the fuck could you convince them you flew? They don't even know what that means. They would have all sorts of questions, and would consider your answers nonsensical or magical. When a non-believer is told that God exists, he reacts in the same way; also, a believer when he is told there is no God.

So everything we believe about the world is built on some sort of foundation. Sure, that foundation can change, but there is always something there at the base, and it is that base that enables us to talk about the world. Not everyone has the same base you do, and that has to be okay. Just know that some of your beliefs are just as unsupported as everyone else's. It's just the way it is, bro.

Often a person uses some folk proverb to explain a behavioral event even though, on an earlier occasion, this same person used a directly contradictory folk proverb to explain the same type of event. For example, most of us have heard or said, “look before you leap.” Now there’s a useful, straightforward bit of behavioral advice—except that I vaguely remember admonishing on occasion, “he who hesitates is lost.” And “absence makes the heart grow fonder” is a pretty clear prediction of an emotional reaction to environmental events. But then what about “out of sight, out of mind”? And if “haste makes waste,” why do we sometimes hear that “time waits for no man”? How could the saying “two heads are better than one” not be true? Except that “too many cooks spoil the broth.” If I think “it’s better to be safe than sorry,” why do I also believe “nothing ventured, nothing gained”? And if “opposites attract,” why do “birds of a feather flock together”? I have counseled many students to “never to put off until tomorrow what you can do today.” But I hope my last advisee has never heard me say this, because I just told him, “cross that bridge when you come to it.”

The enormous appeal of clichés like these is that, taken together as implicit “explanations” of behavior, they cannot be refuted. No matter what happens, one of these explanations will be cited to cover it. No wonder we all think we are such excellent judges of human behavior and personality. We have an explanation for anything and everything that happens. Folk wisdom is cowardly in the sense that it takes no risk that it might be refuted.

ETA: Should have included the subsequent paragraph:

That folk wisdom is “after the fact” wisdom, and that it actually is useless in a truly predictive sense, is why sociologist Duncan Watts titled one of his books: Everything Is Obvious—Once You Know the Answer (2011). Watts discusses a classic paper by Lazarsfeld (1949) in which, over 60 years ago, he was dealing with the common criticism that “social science doesn’t tell us anything that we don’t already know.” Lazarsfeld listed a series of findings from a massive survey of 600,000 soldiers who had served during World War II; for example, that men from rural backgrounds were in better spirits during their time of service than soldiers from city backgrounds. People tend to find all of the survey results to be pretty obvious. In this example, for instance, people tend to think it obvious that rural men would have been used to harsher physical conditions and thus would have adapted better to the conditions of military life. It is likewise with all of the other findings—people find them pretty obvious. Lazarsfeld then reveals his punchline: All of the findings were the opposite of what was originally stated. For example, it was actually the case that men from city backgrounds were in better spirits during their time of service than soldiers from rural backgrounds. The last part of the learning exercise is for people to realize how easily they would have explained just the opposite finding. In the case of the actual outcome, people tend to explain it (when told of it first) by saying that they expected it because city men are used to working in crowded conditions and under hierarchical authority. They never realize how easily they would have concocted an explanation for exactly the opposite finding.

It is now clear to us what, in the year 1812, was the cause of the destruction of the French army. No one will dispute that the cause of the destruction of Napoleon's French forces was, on the one hand, their advance late in the year, without preparations for a winter march, into the depths of Russia, and, on the other hand, the character that the war took on with the burning of Russian towns and the hatred of the foe aroused in the Russian people. But then not only did no one foresee (what now seems obvious) that this was the only way that could lead to the destruction of an army of eight hundred thousand men, the best in the world and led by the best generals, in conflict with a twice weaker Russian army, inexperienced and led by inexperienced generals; not only did no one foresee this, but all efforts on the part of the Russians were constantly aimed at hindering the one thing that could save Russia, and, on the part of the French, despite Napoleon's experience and so-called military genius, all efforts were aimed at extending as far as Moscow by the end of summer, that is, at doing the very thing that was to destroy them.

Already I had learned from thee that because a thing is eloquently expressed it should not be taken to be as necessarily true; nor because it is uttered with stammering lips should it be supposed false. Nor, again, is it necessarily true because rudely uttered, nor untrue because the language is brilliant. Wisdom and folly both are like meats that are wholesome and unwholesome, and courtly or simple words are like town-made or rustic vessels — both kinds of food may be served in either kind of dish.

[Political "gaffe" stories] are completely information-free news events, and they absolutely dominate political news coverage and analysis. It's like asking your doctor if the X-rays show a tumor, and all he'll talk about is how stupid the radiologist's haircut looks. . . . ["Blast"] stories are. . . just as content-free as the "gaffe" stories. But they are popular for the same reason: There's a petty, tribal satisfaction in seeing a member of our team really put the other team in their place. And there's a rush of outrage adrenaline when the other team says something mean about us. So, instead of covering pending legislation or the impact it could have on your life, the news media covers the dick-measuring contest.

Suppose we find a society which lacks our understanding of human physiology, and that speaks a language just like English, except for one curious family of idioms. When they are tired they talk of being beset by fatigues, of having mental fatigues, muscular fatigues, fatigues in the eyes and fatigues of the the spirit. Their sports lore contains such maxims as 'too many fatigues spoils your aim' and 'five fatigues in the legs are worth ten in the arms'. When we encounter them and tell them of our science, they want to know what fatigues are. They have been puzzling over such questions as whether numerically the same fatigue can come and go and return, whether fatigues have a definite location in matter and space and time, whether fatigues are identical with some physical states or processes or events in their bodies, or are made of some sort of stuff. We can see that they are off to a bad start with these questions, but what should we tell them? One thing we can tell them is that there simply are no such things as fatigues - they have a confused ontology. We can expect them to retort: 'You don't think there are fatigues? Run around the block a few times and you'll know better! There are many things your science might teach us, but the non-existence of fatigues isn't one of them!

The first step is to measure whatever can be easily measured. This is OK as far as it goes. The second step is to disregard that which can’t easily be measured or to give it an arbitrary quantitative value. This is artificial and misleading. The third step is to presume that what can’t be measured easily isn’t important. This is blindness. The fourth step is to say that what can’t easily be measured really doesn’t exist.

“Why do you read so much?”

Tyrion looked up at the sound of the voice. Jon Snow was standing a few feet away, regarding him curiously. He closed the book on a finger and said, “Look at me and tell me what you see.”

The boy looked at him suspiciously. “Is this some kind of trick? I see you. Tyrion Lannister.”

Tyrion sighed. “You are remarkably polite for a bastard, Snow. What you see is a dwarf. You are what, twelve?”

“Fourteen,” the boy said.

“Fourteen, and you’re taller than I will ever be. My legs are short and twisted, and I walk with difficulty. I require a special saddle to keep from falling off my horse. A saddle of my own design, you may be interested to know. It was either that or ride a pony. My arms are strong enough, but again, too short. I will never make a swordsman. Had I been born a peasant, they might have left me out to die, or sold me to some slaver’s grotesquerie. Alas, I was born a Lannister of Casterly Rock, and the grotesqueries are all the poorer. Things are expected of me. My father was the Hand of the King for twenty years. My brother later killed that very same king, as it turns out, but life is full of these little ironies. My sister married the new king and my repulsive nephew will be king after him. I must do my part for the honor of my House, wouldn’t you agree? Yet how? Well, my legs may be too small for my body, but my head is too large, although I prefer to think it is just large enough for my mind. I have a realistic grasp of my own strengths and weaknesses. My mind is my weapon. My brother has his sword, King Robert has his warhammer, and I have my mind… and a mind needs books as a sword needs a whetstone, if it is to keep its edge.” Tyrion tapped the leather cover of the book. “That’s why I read so much, Jon Snow.”

I was once, years and years ago, falsely accused by someone of egregious dishonesty, and after I put forward evidence that the accusation was false, was told, "Let's just agree to disagree." At which, of course, I exploded; I would not be agreeing to disagree about whether I had been completely dishonest, thank you very much. And every time someone uses the phrase I am tempted to say, "We don't need to agree to disagree because we already are disagreeing." I think what gets me is that it's such an unbelievably low standard that almost anything would be more intellectually robust; why not agree to something more ambitiously intellectual, like swapping book recommendations, or having a temporary cooling-off period, or going to a third party for arbitration or advice, or anything else, really?

It is of interest that when the [milk] bottle is half filled with milk it is more often described as half empty, but when it is half filled with water it tends to be described as half full. This probably happens because in the case of the milk one is working downward from a full bottle but in the case of the water one is working upward from an empty milk bottle.

After I spoke at the 2005 "Mathematics and Narrative" conference in Mykonos, a suggestion was made that proofs by contradiction are the mathematician's version of irony. I'm not sure I agree with that: when we give a proof by contradiction, we make it very clear that we are discussing a counterfactual, so our words are intended to be taken at face value. But perhaps this is not necessary. Consider the following passage.

There are those who would believe that every polynomial equation with integer coefficients has a rational solution, a view that leads to some intriguing new ideas. For example, take the equation x² - 2 = 0. Let p/q be a rational solution. Then (p/q)² - 2 = 0, from which it follows that p² = 2q². The highest power of 2 that divides p² is obviously an even power, since if 2^k is the highest power of 2 that divides p, then 2^2k is the highest power of 2 that divides p². Similarly, the highest power of 2 that divides 2q² is an odd power, since it is greater by 1 than the highest power that divides q². Since p² and 2q² are equal, there must exist a positive integer that is both even and odd. Integers with this remarkable property are quite unlike the integers we are familiar with: as such, they are surely worthy of further study.

I find that it conveys the irrationality of √2 rather forcefully. But could mathematicians afford to use this literary device? How would a reader be able to tell the difference in intent between what I have just written and the following superficially similar passage?

There are those who would believe that every polynomial equation has a solution, a view that leads to some intriguing new ideas. For example, take the equation x² + 1 = 0. Let i be a solution of this equation. Then i² + 1 = 0, from which it follows that i² = -1. We know that i cannot be positive, since then i² would be positive. Similarly, i cannot be negative, since i² would again be positive (because the product of two negative numbers is always positive). And i cannot be 0, since 0² = 0. It follows that we have found a number that is not positive, not negative, and not zero. Numbers with this remarkable property are quite unlike the numbers we are familiar with: as such, they are surely worthy of further study.

“The goal of the future is full unemployment, so we can play.

Clarke, who found time between scuba diving and pinball games to write “Childhood’s End” and think up communications satellites.

The Puritans turned work into a virtue, evidently forgetting that God invented it as a punishment.

Anyone who values truth should stop worshipping reason. We all need to take a cold hard look at the evidence and see reasoning for what it is. ... [M]ost of the bizarre and depressing research findings [about cognitive biases] make perfect sense once you see reasoning as having evolved not to help us find the truth but to help us engage in arguments, persuasion, and manipulation in the context of discussions with other people.

I'm not saying we should all stop reasoning and go with our gut feelings. Gut feelings are sometimes better guides than reasoning for making consumer choices and interpersonal judgments, but they are often disastrous as a basis for public policy, science, and law. Rather, what I'm saying is that we must be wary of any /individual/'s ability to reason. We should see each individual as being limited, like a neuron. A neuron is really good at one thing: summing up the stimulation coming into its dendrites to 'decide' whether to fire a pulse along its axon. A neuron by itself isn't very smart. But if you put neurons together in the right way you get a brain; you get an emergent system that is much smarter and more flexible than a single neuron.

In the same way, each individual reasoner is really good at one thing: finding evidence to support the position he or she already holds, usually for intuitive reasons. We should not expect individuals to produce good, open-minded, truth-seeking reasoning, particularly when self-interest or reputational concerns are in play. But if you put individuals together in the right way, such that some individuals can use their reasoning powers to disconfirm the claims of others, and all individuals feel some common bond or shared fate that allows them to interact civilly, you can create a group that ends up producing good reasoning as an emergent property of the social system. This is why it's so important to have intellectual and ideological diversity within any group or institution whose goal is to find truth.

A person is said to exhibit rational irrationality when it is instrumentally rational for him to be epistemically irrational. An instrumentally rational person chooses the best strategies to achieve his goals. An epistemically irrational person ignores and evades evidence against his beliefs, holds his beliefs without evidence or with only weak evidence, has contradictions in his thinking, employs logical fallacies in belief formation, and exhibits characteristic epistemic vices such as closed-mindedness. Epistemically irrational political beliefs can reinforce one’s self-image; boost one’s self-esteem; make one feel noble, smart, superior, safe, or comfortable; and can help achieve conformity with the group and thus facilitate social acceptance. Thus, epistemic irrationality can be instrumentally rational.

If I falsely believe the road I am crossing is free of cars, I might die. So I have a strong incentive to form beliefs about the road in a rational way. However, if I falsely believe that import quotas are good for the economy, this has no directly harmful effects. (On the contrary, the belief can have significant instrumental value. It might make me feel patriotic; serve my xenophobia; serve as an outlet to rationalize, sublimate, or redirect racist attitudes; or help me pretend to have solidarity with union workers.) … Epistemic rationality is hard and takes self-discipline.

When it comes to politics, individuals have every incentive to indulge their irrational impulses. Demand for irrational beliefs is like demand for most other goods. The lower the cost, the more will be demanded. The cost to the typical voter of voting in epistemically irrational ways is nearly zero. The cost of overcoming bias and epistemic irrationality is high. The psychological benefit of this irrationality is significant. Thus, voters demand a high amount of epistemic irrationality.

...some people requested that I be prohibited from studying. One time they achieved it through a very holy and simple mother superior who believed that studying would get me in trouble with the Inquisition and ordered me not to do it. I obeyed her for the three months that she was in office in as far as I did not touch a book, but as far as absolutely not studying, this was not in my power. [...] Even the people I spoke to, and what they said to me, gave rise to thousands of reflections. What was the source of all the variety of personality and talent I found among them, since they were all one species? [...] Sometimes I would pace in front of the fireplace in one of our large dormitories and notice that, though the lines of two sides were parallel and its ceiling level, to our vision it appears as though the lines are inclined toward each other and the ceiling is lower in the distance than it is nearby. From this it can be inferred that the lines of our vision run straight, but not parallel, to form the figure of a pyramid. And I wondered if that was the reason that the ancients questioned whether the earth was a sphere or not. Because although it seemed so, their vision might have deceived them, showing concave shapes where there were none. [...] Once I saw two girls playing with a top, and hardly had I seen the movement and the shape when I began, in my insane way, to consider the easy movement of the spherical shape and how long the momentum, once established, remained independent of its original cause, the distant hand of the girl. Not content with this I had flour brought and sprinkled on the floor in order to discover whether the spinning top would describe perfect circles or not. It turned out that they were not perfect circles but spirals that lost their circular shape to the degree that the top lost momentum.

Hey, reporters: don't believe those polls! You can take it as a measure of what respondents think about Trump, if you care about such things, but there's no reason to believe that this kind of self-reporting about vote choice is meaningful at all, and it shouldn't be included in stories about a Trump endorsement as if it was meaningful.

...The bottom line here is that polling is a really good tool for reporters to use in many cases, but remember: what polling tells you for sure is only what people will say if they're asked a question by a pollster.

What really matters is:–

  1. Always try to use the language so as to make quite clear what you mean and make sure your sentence couldn't mean anything else.

  2. Always prefer the plain direct word to the long, vague one. Don't implement promises, but keep them.

  3. Never use abstract nouns when concrete ones will do. If you mean "More people died" don't say "Mortality rose."

  4. In writing. Don't use adjectives which merely tell us how you want us to feel about the thing you are describing. I mean, instead of telling us a thing was "terrible," describe it so that we'll be terrified. Don't say it was "delightful"; make us say "delightful" when we've read the description. You see, all those words (horrifying, wonderful, hideous, exquisite) are only like saying to your readers, "Please will you do my job for me."

  5. Don't use words too big for the subject. Don't say "infinitely" when you mean "very"; otherwise you'll have no word left when you want to talk about something really infinite.

...a good way of thinking about minimalism [about truth] and its attractions is to see it as substituting the particular for the general. It mistrusts anything abstract or windy. Both the relativist and the absolutist are impressed by Pilate's notorious question 'What is Truth?', and each tries to say something useful at the same high and vertiginous level of generality. The minimalist can be thought of turning his back on this abstraction, and then in any particular case he prefaces his answer with the prior injunction: you tell me. This does not mean, 'You tell me what truth is.' It means, 'You tell me what the issue is, and I will tell you (although you will already know, by then) what the truth about the issue consists in.' If the issue is whether high tide is at midday, then truth consists in high tide being at midday... We can tell you what truth amounts to, if you first tell us what the issue is.

There is a very powerful argument for minimalism about truth, due to the great logician Gottlob Frege. First, we should notice the transparency property of truth. This is the fact that it makes no difference whether you say that it is raining, or it is true that it is raining, or true that it is true that it is raining, and so on forever. But if 'it is true that' introduced some substantial, robust property of a judgment, how could this be so? Consider, for example, a pragmatism that attempts some equation between truth and utility. Then next to the judgment 'it is raining' we might have 'it is useful to believe that it is raining.' But these are entirely different things! To assess the first we direct our attention to the weather. To assess the second we direct our attention to the results of believing something about the weather - a very different investigation.

Let us return to Pilate. Where does minimalism about truth leave him? It suggests that when he asked this question, he was distracting himself and his audience from his real job, which was to find out whether to uphold certain specific historical charges against a defendant. Thus, if I am innocent, and I come before a judge, I don't want airy generalities about the nature of truth. I want him to find that I did not steal the watch if I did not steal the watch. I want him to rub his nose in the issue. I want a local judgment about a local or specific event, supposed to have happened in a particular region of time and space.

"In a society in which the narrow pursuit of material self-interest is the norm, the shift to an ethical stance is more radical than many people realize. In comparison with the needs of people starving in Somalia, the desire to sample the wines of the leading French vineyards pales into insignificance. Judged against the suffering of immobilized rabbits having shampoos dripped into their eyes, a better shampoo becomes an unworthy goal. An ethical approach to life does not forbid having fun or enjoying food and wine, but it changes our sense of priorities. The effort and expense put into buying fashionable clothes, the endless search for more and more refined gastronomic pleasures, the astonishing additional expense that marks out the prestige car market in cars from the market in cars for people who just want a reliable means to getting from A to B, all these become disproportionate to people who can shift perspective long enough to take themselves, at least for a time, out of the spotlight. If a higher ethical consciousness spreads, it will utterly change the society in which we live." -- Peter Singer

The last project that I worked on with [Richard Feynman] was in simulated evolution. I had written a program that simulated the evolution of populations of sexually reproducing creatures over hundreds of thousands of generations. The results were surprising in that the fitness of the population made progress in sudden leaps rather than by the expected steady improvement. The fossil record shows some evidence that real biological evolution might also exhibit such "punctuated equilibrium," so Richard and I decided to look more closely at why it happened. He was feeling ill by that time, so I went out and spent the week with him in Pasadena, and we worked out a model of evolution of finite populations based on the Fokker Planck equations. When I got back to Boston I went to the library and discovered a book by Kimura on the subject, and much to my disappointment, all of our "discoveries" were covered in the first few pages. When I called back and told Richard what I had found, he was elated. "Hey, we got it right!" he said. "Not bad for amateurs."

One in four Americans has an opinion about an imaginary debt plan

A new poll from Public Policy Polling found that an impressive 39 percent of Americans have an opinion about the Simpson-Bowles deficit reduction plan.

Before you start celebrating the new, sweeping reach of the 2010 commission’s work, consider this: Twenty-five percent of Americans also took a stance on the Panetta-Burns plan.

What’s that? You’re not familiar with Panetta-Burns? That’s probably because its “a mythical Clinton Chief of Staff/former western Republican Senator combo” that PPP dreamed up to test how many Americans would profess to have an opinion about a policy that did not exist. They found one in four voters to do just that.

Panetta-Burns’ nonexistent policy proposals were supported by 8 percent and opposed by 17 percent of the voters surveyed. Simpson-Bowles’ real policy proposals had stronger favorables, with 23 percent support and 16 percent opposition.

The tendency toward generalization doesn’t bother me in an of itself, rather, I’m focused on whether the proposition is true. But the hypocrisy gets tiresome sometimes, as people will fluidly switch from a cognitive style which accepts generalization to one which rejects it. A stereotype is often a generalization whose robustness you don’t want to accept. Negative generalities need context when they’re unpalatable, but no qualification is necessary when their truth is congenial.

Does access to information change the expectation that if you can know, you will know?

I am reminded of a commentary on logic puzzles of a certain kind; it was perhaps in a letter to Martin Gardner, reprinted in one of his books. The puzzles are those about getting about on an island where each native either always tells the truth or always lies. You reach a fork in the road, for example, and a native is standing there, and you want to learn from him, with one question, which way leads to the village. The “correct” question is “If I asked you if the left way led to the village, would you say yes?” But why should the native’s concept of lying conform to our own logical ideas? If the native is a liar, it means he wants to fool you, and your logical trickery will not work. The best you can do is say something like “Did you hear they are giving away free beer in the village today?” and see which way the native runs. You follow him, even if he says something like “Ugh, I hate beer!” since then he probably really is lying.

Lastly, there is an attitude not unknown in the crisis against which I should particularly like to protest. I should address my protest especially to those lovers and pursuers of Peace who, very short-sightedly, have occasionally adopted it. I mean the attitude which is impatient of these preliminary details about who did this or that, and whether it was right or wrong. They are satisfied with saying that an enormous calamity, called War, has been begun by some or all of us; and should be ended by some or all of us. To these people this preliminary chapter about the precise happenings must appear not only dry (and it must of necessity be the driest part of the task) but essentially needless and barren. I wish to tell these people that they are wrong; that they are wrong upon all principles of human justice and historic continuity: but that they are specially and supremely wrong upon their own principles of arbitration and international peace.

These sincere and high-minded peace-lovers are always telling us that citizens no longer settle their quarrels by private violence; and that nations should no longer settle theirs by public violence. They are always telling us that we no longer fight duels; and need no longer wage wars. In short, they perpetually base their peace proposals on the fact that an ordinary citizen no longer avenges himself with an axe. But how is he prevented from revenging himself with an axe? If he hits his neighbour on the head with the kitchen chopper, what do we do? Do we all join hands, like children playing Mulberry Bush, and say "We are all responsible for this; but let us hope it will not spread. Let us hope for the happy day when he shall leave off chopping at the man's head; and when nobody shall ever chop anything for ever and ever." Do we say "Let byegones be byegones; why go back to all the dull details with which the business began; who can tell with what sinister motives the man was standing there within reach of the hatchet?" We do not. We keep the peace in private life by asking for the facts of provocation, and the proper object of punishment. We do go into the dull details; we do enquire into the origins; we do emphatically enquire who it was that hit first. In short we do what I have done very briefly in this place.

The inhabitants of Florence in 1494 or Athens in 404 BCE could be forgiven for concluding that optimism just isn't factually true. For they knew nothing of such things as the reach of explanations or the power of science or even laws of nature as we understand them, let alone the moral and technological progress that was to follow when the Enlightenment got under way. At the moment of defeat, it must have seemed at least plausible to the formerly optimistic Athenians that the Spartans might be right, and to the formerly optimistic Florentines that Savonarola might be. Like every other destruction of optimism, whether in a whole civilization or in a single individual, these must have been unspeakable catastrophes for those who had dared to expect progress. But we should feel more than sympathy for those people. We should take it personally. For if any of those earlier experiments in optimism had succeeded, our species would be exploring the stars by now, and you and I would be immortal.

Unfortunately, he tested his hunch by palpating the patient's tongue, without washing his hands between patients. When patient after patient became ill, the physician developed a sense of clinical infallibility. His predictions were accurate--but not because he was exercising professional intuition!

The reason you can't rigidly separate positive from normative economics is that you can't rigidly separate claims of fact from claims of value in general. Human language is too laden with thick concepts that mix the two. The claim that someone is a "slut" or a "bitch", for example, melds together factual claims about a woman's behavior with a lot of deeply embedded normative concepts about what constitutes appropriate behavior for a woman. The claim that financial markets are "efficient" is both an effort to describe their operation and a way of valorizing them. The idea of a "recession" or "full employment" or "potential output" all embed certain ideas about what would constitute a normal arrangement of human economic activity (...) You could try to rigorously purge your descriptions of the economy of anything that vaguely smells of a thick moral concept, but you'd find yourself operating with an impoverished vocubulary unable to describe human affairs in any kind of reasonable way.

[Hitler] has grasped the falsity of the hedonistic attitude to life. Nearly all western thought since the last war, certainly all "progressive" thought, has assumed tacitly that human beings desire nothing beyond ease, security, and avoidance of pain. In such a view of life there is no room, for instance, for patriotism and the military virtues. The Socialist who finds his children playing with soldiers is usually upset, but he is never able to think of a substitute for the tin soldiers; tin pacifists somehow won’t do. Hitler, because in his own joyless mind he feels it with exceptional strength, knows that human beings don’t only want comfort, safety, short working-hours, hygiene, birth-control and, in general, common sense; they also, at least intermittently, want struggle and self-sacrifice, not to mention drums, flag and loyalty-parades.

However they may be as economic theories, Fascism and Nazism are psychologically far sounder than any hedonistic conception of life. The same is probably true of Stalin’s militarized version of Socialism. All three of the great dictators have enhanced their power by imposing intolerable burdens on their peoples. Whereas Socialism, and even capitalism in a grudging way, have said to people "I offer you a good time," Hitler has said to them "I offer you struggle, danger and death," and as a result a whole nation flings itself at his feet.

The Patrician steepled his hands and looked at Vimes over the top of them.

"Let me give you some advice, Captain," he said.

"Yes, sir?"

"It may help you make some sense of the world."

"Sir."

"I believe you find life such a problem because you think there are the good people and the bad people," said the man. "You're wrong, of course. There are, always and only, the bad people, but some of them are on opposite sides. "

He waved his thin hand towards the city and walked over to the window.

"A great rolling sea of evil," he said, almost proprietorially. "Shallower in some places, of course, but deeper, oh, so much deeper in others. But people like you put together little rafts of rules and vaguely good intentions and say, this is the opposite, this will triumph in the end. Amazing!" He slapped Vimes good-naturedly on the back.

"Down there," he said, "are people who will follow any dragon, worship any god, ignore any iniquity. All out of a kind of humdrum, everyday badness. Not the really high, creative loathesomeness of the great sinners, but a sort of mass-produced darkness of the soul. Sin, you might say, without a trace of originality. They accept evil not because they say yes, but because they don't say no. I'm sorry if this offends you,'' he added, patting the captain's shoulder, "but you fellows really need us."

"Yes, sir?" said Vimes quietly.

"Oh, yes. We're the only ones who know how to make things work. You see, the only thing the good people are good at is overthrowing the bad people. And you're good at that, I'll grant you. But the trouble is that it's the only thing you're good at. One day it's the ringing of the bells and the casting down of the evil tyrant, and the next it's everyone sitting around complaining that ever since the tyrant was overthrown no-one's been taking out the trash. Because the bad people know how to plan. It's part of the specification, you might say. Every evil tyrant has a plan to rule the world. The good people don't seem to have the knack."

"Maybe. But you're wrong about the rest!" said Vimes. "It's just because people are afraid, and alone-" He paused. It sounded pretty hollow, even to him.

He shrugged. "They're just people," he said. "They're just doing what people do. Sir."

Lord Vetinari gave him a friendly smile. "Of course, of course," he said. "You have to believe that, I appreciate. Otherwise you'd go quite mad. Otherwise you'd think you're standing on a feather-thin bridge over the vaults of Hell. Otherwise existence would be a dark agony and the only hope would be that there is no life after death. I quite understand."

(...)

After a while he made a few pencil annotations to the paper in front of him and looked up.

"I said," he said, "that you may go."

Vimes paused at the door.

"Do you believe all that, sir?" he said. "About the endless evil and the sheer blackness?"

"Indeed, indeed," said the Patrician, turning over the page. "It is the only logical conclusion."

"But you get out of bed every morning, sir?"

"Hmm? Yes? What is your point?"

"I'd just like to know why, sir."

"Oh, do go away, Vimes. There's a good fellow."

Long quote to make a simple point, but relevant. (Context: this is from a Star Wars novel, so it's fiction.)

A death hollow is a low point where the heavier-than-air toxic gases that roll downslope from the volcanoes can pool.

The corpse of a hundred-kilo tusker lay just within its rim, its snout only a meter below the clear air that could have saved it. Other corpses littered the ground around it: rot crows and jacunas and other small scavengers I didn't recognize, lured to their deaths by the jungle's false promise of an easy meal.

I said something along these lines to Nick. He laughed and called me a Balawai fool.

"There's no false promise," he'd said. "There's no promise at all. The jungle doesn't promise. It exists. That's all. What killed those little ruskakks wasn't a trap. It was just the way things are."

Nick says that to talk of the jungle as a person-to give it the metaphoric aspect of a creature, any creature-that's a Balawai thing. That's part of what gets them killed out here.

It's a metaphor that shades the way you think: talk of the jungle as a creature, and you start treating it like a creature. You start thinking you can outsmart the jungle, or trust it, overpower it or befriend it, deceive it or bargain with it.

And then you die.

"Not because the jungle kills you. You get it? Just because it is what it is." These are Nick's words. "The jungle doesn't do anything. It's just a place. It's a place where many, many things live... and all of them die. Fantasizing about it - pretending it's something it's not - is fatal. That's your free life lesson for the day," he told me. "Keep it in mind."

I will.

It is very difficult to find a black cat in a dark room, especially if the cat is not there.

— Confucius, allegedly (quoted in The Meeting Place Cannot Be Changed)

Edit: The rationality relevance might need some explanation. The way I've seen this aphorism used is this: it's sometimes hard to distinguish between a task that's achievable but very difficult (and that it therefore might make sense to spend time/effort on), and a task that is impossible (and thus is a complete waste of time/effort).

If you spend some time searching for the cat in the dark room, you might not find it. Is that because finding it is difficult (after all, this is what you might quite plausibly expect, if you assume that the cat is there), or because the cat is not there and you're wasting your time?

To be a good diagnostician, a physician needs to acquire a large set of labels for diseases, each of which binds an idea of the illness and its symptoms, possible antecedents and causes, possible developments and consequences, and possible interventions to cure or mitigate the illness. Learning medicine consists in part of learning the language of medicine. A deeper understanding of judgments and choices also requires a richer vocabulary than is available in everyday language. The availability of a diagnostic label for [the] bias... makes it easier to anticipate, recognize and understand.

I believe I am accurate in saying that educators too are interested in learnings which make a difference. Simple knowledge of facts has its value. To know who won the battle of Poltava, or when the umpteenth opus of Mozart was first performed, may win $64,000 or some other sum for the possessor of this information, but I believe educators in general are a little embarrassed by the assumption that the acquisition of such knowledge constitutes education. Speaking of this reminds me of a forceful statement made by a professor of agronomy in my freshman year in college. Whatever knowledge I gained in his course has departed completely, but I remember how, with World War I as his background, he was comparing factual knowledge with ammunition. He wound up his little discourse with the exhortation, "Don't be a damned ammunition wagon; be a rifle!"

Our minds contain processes that enable us to solve problems we consider difficult. "Intelligence" is our name for whichever of those processes we don't yet understand.

Some people dislike this "definition" because its meaning is doomed to keep changing as we learn more about psychology. But in my view that's exactly how it ought to be, because the very concept of intelligence is like a stage magician's trick. Like the concept of "the unexplored regions of Africa," it disappears as soon as we discover it.

I don't think winners beat the competition because they work harder. And it's not even clear that they win because they have more creativity. The secret, I think, is in understanding what matters.

It's not obvious, and it changes. It changes by culture, by buyer, by product and even by the day of the week. But those that manage to capture the imagination, make sales and grow are doing it by perfecting the things that matter and ignoring the rest.

"Because they were hypocrites," Finkle-McGraw said, after igniting his calabash and shooting a few tremendous fountains of smoke into the air, "the Victorians were despised in the late twentieth century. Many of the persons who held such opinions were, of course, guilty of the most nefandous conduct themselves, and yet saw no paradox in holding such views because they were not hypocrites themselves-they took no moral stances and lived by none."

"So they were morally superior to the Victorians-" Major Napier said, still a bit snowed under. "-even though-in fact, because-they had no morals at all." There was a moment of silent, bewildered head-shaking around the copper table.

"We take a somewhat different view of hypocrisy," Finkle-McGraw continued. "In the late-twentieth-century Weltanschauung, a hypocrite was someone who espoused high moral views as part of a planned campaign of deception-he never held these beliefs sincerely and routinely violated them in privacy. Of course, most hypocrites are not like that. Most of the time it's a spirit-is-willing, flesh-is-weak sort of thing."

"That we occasionally violate our own stated moral code," Major Napier said, working it through, "does not imply that we are insincere in espousing that code."

"Of course not," Finkle-McGraw said. "It's perfectly obvious, really. No one ever said that it was easy to hew to a strict code of conduct. Really, the difficulties involved-the missteps we make along the way are what make it interesting. The internal, and eternal, struggle, between our base impulses and the rigorous demands of our own moral system is quintessentially human. It is how we conduct ourselves in that struggle that determines how we may in time be judged by a higher power."

The word problem may be an insidious form of question-begging. To speak of the Jewish problem is to postulate that the Jews are a problem; it is to predict (and recommend) persecution, plunder, shooting, beheading, rape, and the reading of Dr. Rosenberg's prose. Another disadvantage of fallacious problems is that they bring about solutions that are equally fallacious. Pliny (Book VIII of Natural History) is not satisfied with the observation that dragons attack elephants in the summer; he ventures the hypothesis that they do it in order to drink the elephants' blood, which, as everyone knows, is very cold.

But personally I do not believe that they think anything of the kind. I believe they put food or weapons on the dead for the same reason that we put flowers, because it is an exceedingly natural and obvious thing to do.

I prefer this sort of distant, reductionist, structural approach to analysing the race because there's little reason to believe in the validity of the implicit theories or "models" lurking behind pundits' gut judgments. When I heard Mr Romney's 47% comments, I thought "Oooh, he's toast!" and then I stopped myself and acknowledged that I actually have no rational basis for believing that his remarks would in the final analysis hurt Mr Romney at all. What percentage of undecided or weakly-decided swing-state voters ever caught wind of Mr Romney's embarrassing chat? I didn't know! Of those who became aware of it, how many cared? I didn't know! So why did I think "Oooh, he's toast!" Because I am human, and I make most judgments and decisions on the basis of crackpot hunches, the underlying logic of which is almost completely inscrutable to me.

Despite the difficulty of exact Bayesian inference in complex mathematical models, the essence of Bayesian reasoning is frequently used in everyday life. One example has been immortalized in the words of Sherlock Holmes to his friend Dr. Watson: “How often have I said to you that when you have eliminated the impossible, whatever remains, however improbable, must be the truth?” (Arthur Conan Doyle, The Sign of Four, 1890, Ch. 6). This reasoning is actually a consequence of Bayesian belief updating, as expressed in Equation 4.4. Let me re-state it this way: “How often have I said to you that when p(D|θ_i ) = 0 for all i!=j, then, no matter how small the prior p(θ_j ) 0 is, the posterior p(θ_j |D) must equal one.” Somehow it sounds better the way Holmes said it.

“The general method that Wittgenstein does suggest is that of ’shewing that a man has supplied no meaning for certain signs in his sentences’.

I can illustrate the method from Wittgenstein’s later way of discussing problems. He once greeted me with the question: ‘Why do people say that it was natural to think that the sun went round the earth rather than that the earth turned on its axis? I replied: ‘I suppose, because it looked as if the sun went round the earth.’ ‘Well,’ he asked, ‘what would it have looked like if it had looked as if the earth turned on its axis?’

This question brought it out that I had hitherto given no relevant meaning to ‘it looks as if’ in ‘it looks as if the sun goes round the earth’.

My reply was to hold out my hands with the palms upward, and raise them from my knees in a circular sweep, at the same time leaning backwards and assuming a dizzy expression. ‘Exactly!’ he said.”

When we were first drawn together as a society, it had pleased God to enlighten our minds so far as to see that some doctrines, which we once esteemed truths, were errors; and that others, which we had esteemed errors, were real truths. From time to time He has been pleased to afford us farther light, and our principles have been improving, and our errors diminishing.

Now we are not sure that we are arrived at the end of this progression, and at the perfection of spiritual or theological knowledge; and we fear that, if we should once print our confession of faith, we should feel ourselves as if bound and confin'd by it, and perhaps be unwilling to receive farther improvement, and our successors still more so, as conceiving what we their elders and founders had done, to be something sacred, never to be departed from.

Slogans like “practice random acts of kindness” feel good and are easy to put into practice. But if we don’t take our activism more seriously than that, our motive is probably a desire to feel good about ourselves, to help ourselves or those close to us, or to act out our self-identity. The endpoint of authentic compassion is a desire to do the most good that one can, to be as effective as possible in creating a world with less suffering and destruction and more joy. Figuring out how we can do the most good takes careful thought over a long period of time, and it means moving into new and possibly uncomfortable areas of advocacy. But the importance of taking our activism seriously and approaching it from this utilitarian perspective cannot be overstated. It will mean a difference between life and death, between happiness and suffering, for thousands of people, for thousands of acres of the ecosystem, and for tens of thousands of animals.

Recognizing the startling resurgence in realism, Don Philahue (of The Don Philahue Show) invited a member of Realists Anonymous to bare his soul on television. After a brief introduction documenting the spread of realism, Philahue turned to his guest:

DP: And causality, what about causality?

H: That too, Don. (Audience gasps.)

DP: I'm going to press you here, Hilary. Did you at any time accept moral realism?

H: (staring at feet): Yes.

DP: What effect did all this realism have on your life?

DP: There was worse, wasn't there Hilary?

H: I can't deny it, don. (Audience gasps.) Instead of going to work I would sit at home fondling ashtrays and reading voraciously about converging scientific theories. I kept a copy of "Hitler: A Study in Tyranny" hidden in the icebox, and when no one was around I would take it our and chant "The Nazis were bad. The Nazis were really bad."

When you have run the length of various practices and none of those practices remain in your mind, that very lack of mind itself is the heart of "all things." When you have exhaustively learned the various practices and techniques and made great effort in disciplined training, there will be action in your arms, legs, and body but none in your mind; you will have distanced yourself from training, but will not be in opposition to it, and you will have freedom in whatever techniques you perform. You yourself will be unaware of where your mind is, and neither demons nor heresies will be able to find it.

A critical analysis of the present global constellation -- one which offers no clear solution, no "practical" advice on what to do, and provides no light at the end of the tunnel, since one is well aware that this light might belong to a train crashing towards us -- usually meets with reproach: "Do you mean we should do nothing? Just sit and wait?" One should gather the courage to answer: "YES, precisely that!" There are situations when the only truly "practical" thing to do is to resist the temptation to engage immediately and to "wait and see" by means of a patient, critical analysis.

When people talk about the importance of democracy, it is never democracy as it has ever actually functioned, with the politicians that have actually been elected, and the policies that have actually been implemented. It is always democracy as people imagine it will operate once they succeed in electing "the right people" — by which they mean, people who agree almost completely with their own views, and who are consistent and incorruptible in their implementation of the resulting policies.

--Ben O'Neill, here

Considering the above quote can be used to criticize nearly any popular political position I don't think it is inherently mind-killing. Also since we all agree democracy is a good thing this isn't even very political. The original article and context obviously does make it somewhat political.

"Stay, 'tis just a figure!" Root laughed rather winningly, reaching out to touch Locke's shoulder.

"A faulty one," Daniel said, "for you are an alchemist."

"I am called an Alchemist. Within living memory, Daniel, everyone who studied what I—and you—study was called by that name. And most persons even today observe no distinction between Alchemy and the younger and more vigorous order of knowledge that is associated with your club."

"I am too exhausted to harry you through all of your evasions. Out of respect for your friends Mr. Locke, and for Leibniz, I shall give you the benefit of the doubt, and wish you well," Daniel said.

"God save you, Mr. Waterhouse."

"And you, Mr. Root. But I say this to you—and you as well, Mr. Locke. As I came in here I saw a map, lately taken from this house, burning in the fire. The map was empty, for it depicted the ocean—most likely, a part of it where no man has ever been. A few lines of latitude were ruled across that vellum void, and some legendary isles drawn in, with great authority, and where the map-maker could not restrain himself he drew phantastickal monsters. That map, to me, is Alchemy. It is good that it burnt, and fitting that it burnt tonight, the eve of a Revolution that I will be so bold as to call my life's work. In a few years Mr. Hooke will learn to make a proper chronometer, finishing what Mr. Huygens began thirty years ago, and then the Royal Society will draw maps with lines of longitude as well as latitude, giving us a grid— what we call a Cartesian grid, though 'twas not his idea—and where there be islands, we will rightly draw them. Where there are none, we will draw none, nor dragons, nor sea-monsters—and that will be the end of Alchemy."

The atmosphere of political parties, whether in France or England, is not congenial to the formation of an impartial judgment. A Minister, who is in the thick of a tough parliamentary struggle, must use whatever arguments he can to defend his cause without inquiring too closely whether they are good, bad, or indifferent. However good they may be, they will probably not convince his political opponents, and they can scarcely be so bad as not to carry some sort of conviction to the minds of those who are predisposed to support him.

(For example, something like 75% of Americans will report they voted for President Obama, which disagrees quite a bit with the ballot box. They do this partially because they misremember their own behavior and partially because they like to been seen as the type of person who voted for the winner. 99% of geeks will report never having bought anything as a result of an email. They do this because they misremember their own behavior and partially because they believe that buying stuff from “spam” is something that people with AOL email addresses do, and hence admitting that they, too, can be marketed to will cause them to lose status. The AppSumo sumo would be a good deal skinnier if that were actually the case, but geeks were all people before they were geeks, and people are statistically speaking terrible at introspection.)

I begin with the assumption that suffering and death from lack of food, shelter, and medical care are bad. I think most people will agree about this, although one may reach the same view by different routes. I shall not argue for this view. People can hold all sorts of eccentric positions, and perhaps from some of them it would not follow that death by starvation is in itself bad. It is difficult, perhaps impossible, to refute such positions, and so for brevity I will henceforth take this assumption as accepted. Those who disagree need read no further.

M. Mitchell Waldrop on a meeting between physicists and economists at the Santa Fe Institute:

...as the axioms and theorems and proofs marched across the overhead projection screen, the physicists could only be awestruck at [the economists'] mathematical prowess — awestruck and appalled. They had the same objection that [Brian] Arthur and many other economists had been voicing from within the field for years. "They were almost too good," says one young physicist, who remembers shaking his head in disbelief. "lt seemed as though they were dazzling themselves with fancy mathematics, until they really couldn't see the forest for the trees. So much time was being spent on trying to absorb the mathematics that I thought they often weren't looking at what the models were for, and what they did, and whether the underlying assumptions were any good. In a lot of cases, what was required was just some common sense. Maybe if they all had lower IQs, they'd have been making some better models.”

He himself is a strong proponent of these simulations. Monte Carlo simulations are simply the way we do the math with uncertain quantities.

The ultimate theological question is: ‘Where does the Sun go at night?’.

The answer that so many civilisations agreed for so long was: ‘The Sun is driven by one of the gods, and at night it goes under the Earth to fight a battle. There is at least some risk that the god will lose this battle, and so the Sun may not rise tomorrow’. It’s something the human race understood was a cast iron fact before they knew how to cast iron. It survived as the working model twenty-five times longer than the four hundred years we’ve understood the Earth goes around the Sun.

This is less a rationality quote than a "yay science" quote, but I find that impressive beyond words.

But even as light is opposed by darkness, science and reason have their enemies. Superstition and belief in magic are as old as man himself; for the intransigence of facts and our limitations in controlling them can be powerfully hard to take. Add to this the reflection that we are in an age when it is popular to distrust whatever is seen as the established view or the Establishment, and it is no wonder that anti-rational attitudes and doctrines are mustering so much support. Still, we can understand what encourages the anti-rationalist turn without losing our zeal for opposing it. A current Continuing Education catalogue offers a course description, under the heading "Philosophy", that typifies the dark view at its darkest: "Children of science that we are, we have based our cultural patterns on logic, on the cognitive, on the verifiable. But more and more there has crept into current research and study the haunting suggestion that there are other kinds of knowledge unfathomable by our cognition, other ways of knowing beyond the limits of our logic, which are deserving of our serious attention." Now "knowledge unfathomable by our cognition" is simply incoherent, as attention to the words makes clear. Moreover, all that creeps is not gold. One wonders how many students enrolled.

Whether a mathematical proposition is true or not is indeed independent of physics. But the proof of such a proposition is a matter of physics only. There is no such thing as abstractly proving something, just as there is no such thing as abstractly knowing something. Mathematical truth is absolutely necessary and transcendent, but all knowledge is generated by physical processes, and its scope and limitations are conditioned by the laws of nature.

[Instrumentalism about science] has a long and rather sorry philosophical history: most contemporary philosophers of science regard it as fairly conclusively refuted. But I think it’s easier to see what’s wrong with it just by noticing that real science just isn’t like this. According to instrumentalism, palaeontologists talk about dinosaurs so they can understand fossils, astrophysicists talk about stars so they can understand photoplates, virologists talk about viruses so they can understand NMR instruments, and particle physicists talk about the Higgs Boson so they can understand the LHC. In each case, it’s quite clear that instrumentalism is the wrong way around. Science is not “about” experiments; science is about the world, and experiments are part of its toolkit.

Prompted by Maniakes, but sufficiently different to post separately:

It cannot have escaped philosophers' attention that our fellow academics in other fields--especially in the sciences--often have difficulty suppressing their incredulous amusement when such topics as Twin Earth, Swampman, and Blockheads are posed for apparently serious consideration. Are the scientists just being philistines, betraying their tin ears for the subtleties of philosophical investigation, or have the philosophers who indulge in these exercises lost their grip on reality?

These bizarre examples all attempt to prove one "conceptual" point or another by deliberately reducing something underappreciated to zero, so that What Really Counts can shine through. Blockheads hold peripheral behavior constant and reduce internal structural details (and--what comes to the same thing--intervening internal processes) close to zero, and provoke the intuition that then there would be no mind there; internal structure Really Counts. Manthra is more or less the mirror-image; it keeps internal processes constant and reduces control of peripheral behavior to zero, showing, presumably, that external behavior Really Doesn't Count. Swampman keeps both future peripheral dispositions and internal states constant and reduces "history" to zero. Twin Earth sets internal similarity to maximum, so that external context can be demonstrated to be responsible for whatever our intuitions tell us. Thus these thought experiments mimic empirical experiments in their design, attempting to isolate a crucial interaction between variables by holding other variables constant. In the past I have often noted that a problem with such experiments is that the dependent variable is "intuition"--they are intuition pumps--and the contribution of imagination in the generation of intuitions is harder to control than philosophers have usually acknowledged.

But there is also a deeper problem with them. It is child's play to dream up further such examples to "prove" further conceptual points. Suppose a cow gave birth to something that was atom-for-atom indiscernible from a shark. Would it be a shark? What is the truth-maker for sharkhood? If you posed that question to a biologist, the charitable reaction would be that you were making a labored attempt at a joke. Suppose an evil demon could make water turn solid at room temperature by smiling at it; would demon-water be ice? Too silly a hypothesis to deserve a response. All such intuition pumps depend on the distinction spelled out by McLaughlin and O'Leary-Hawthorne between "conceptual" and "reductive" answers to the big questions. What I hadn't sufficiently appreciated in my earlier forthright response to Jackson is that when one says that the truth-maker question requires a conceptual answer, one means an answer that holds not just in our world, or all nomologically possible worlds, but in all logically possible worlds. Smiling demons, cow-sharks, Blockheads, and Swampmen are all, some philosophers think, logically possible, even if they are not nomologically possible, and these philosophers think this is important. I do not. Why should the truth-maker question cast its net this wide? Because, I gather, otherwise its answer doesn't tell us about the essence of the topic in question. But who believes in real essences of this sort nowadays? Not I.

The human understanding is no dry light, but receives an infusion from the will and affections; whence proceed sciences which may be called "sciences as one would." For what a man had rather were true he more readily believes. Therefore he rejects difficult things from impatience of research; sober things, because they narrow hope; the deeper things of nature, from superstition; the light of experience, from arrogance and pride, lest his mind should seem to be occupied with things mean and transitory; things not commonly believed, out of deference to the opinion of the vulgar. Numberless, in short, are the ways, and sometimes imperceptible, in which the affections color and infect the understanding.

But when we have these irrational beliefs, these culturally coded assumptions, running so deep within our community and movement, how do we actually change that? How do we get people to further question themselves when they’ve already become convinced that they’re a rational person, a skeptic, and have moved on from irrationality, cognitive distortion and bias?

Well I think what we need to do is to change the fundamental structure and values of skepticism. We need to build our community and movement around slightly different premises.

As it has stood in the past, skepticism has been predicated on a belief in the power of the empirical and rational. It has been based on the premise that there is an empirical truth, and that it is knowable, and that certain tools and strategies like science and logic will allow us to reach that truth. In short, the “old guard” skepticism was based on a veneration of the rational. But the veneration of certain techniques or certain philosophies creates the problematic possibility of choosing to consider certain conclusions or beliefs to BE empirical and rational and above criticism, particularly beliefs derived from the “right” tools, and even more dangerously, to consider oneself “rational”.

...

I believe that in order to be able to question our own beliefs as well as we question those of others, we need to restructure skepticism around awareness of human limitation, irrationality and flaws. Rather than venerating the rational, and aspiring to become some kind of superhuman fully rational vulcan minds, we need to instead create a more human skepticism, built around understanding how belief operates, how we draw conclusions, and how we can cope with the human limitations. I believe we need to remove the focus from aspiring towards ridding ourselves of the irrational, and instead move the focus towards understanding how this irrationality operates and why we believe all the crazy things we believe. We need to position as our primary aspiration not the achievement of a perfect comprehending mind, but instead an ability to maintain constant hesitation and doubt, to always always ALWAYS second-guess our positions and understand that they’re being created through a flawed mind, from flawed perceptions.

Science and reason are excellent tools to allow us to cope with being crazy, irrational human beings, but it CANNOT allow us to transcend that. The instant we begin to believe that we have become A Skeptic, A Rational Person, that is when we’ve fucked up, that is when we stop practicing skepticism, stop keeping an eye out for our mistakes, and begin to imagine our irrational perceptions as perfect rational conclusions. It’s only by building a skepticism based on the practice of doubt, rather than the state of Skeptic, that we’ll truly be able to be move on from our assumptions.

If we see in each generation the conflict of the future against the past, the fight of what might be called progressive versus reactionary, we shall find ourselves organizing the historical story upon what is really an unfolding principle of progress, and our eyes will be fixed upon certain people who appear as the special agencies of that progress. [...] But if we see in each generation a clash of wills out of which there emerges something that probably no man ever willed, our minds become concentrated upon the process that produced such an unpredictable issue, and we are more open for an intensive study of the motions and interactions that underlie historical change. [...] The process of the historical transition will then be recognized to be unlike what the whig historian seems to assume – much less like the procedure of a logical argument and perhaps much more like the method by which a man can be imagined to work his way out of a "complex". It is a process which moves by mediations and those mediations may be provided by anything in the world – by men’s sins or misapprehensions or by what we can only call fortunate conjunctures. Very strange bridges are used to make the passage from one state of things to another; we may lose sight of them in our surveys of general history, but their discovery is the glory of historical research. History is not the study of origins; rather it is the analysis of all the mediations by which the past was turned into our present.

The God hypothesis, for instance, gives one an unparalleled ability to understand absolutely everything, while discovering absolutely nothing... Give a person a highly simplified model of the world and interpret any event on the basis of this simplified model. Such an approach required no knowledge.

On specificity and sneaking on connotations; useful for the liberal-minded among us:

I think, with racism and sexism and 'isms' generally, there's a sort of confusion of terminology.

A "Racist1" is someone, who, like a majority of people in this society, has subconsciously internalized some negative attitudes about minority racial groups. If a Racist1 takes the Implicit Association Test, her score shows she's biased against black people, like the majority of people (of all races) who took the test. Chances are, whether you know it or not, you're a Racist1.

A "Racist2" is someone who's kind of an insensitive jerk about race. The kind of guy who calls Obama the "Food Stamp President." Someone you wouldn't want your sister dating.

A "Racist3" is a neo-Nazi. You can never be quite sure that one day he won't snap and kill someone. He's clearly a social deviant.

People use the word "Racist" for all three things, and I think that's the source of a lot of arguments. When people get accused of being racists, they evade responsibility by saying, "Hey, I'm not a Racist3!" when in fact you were only saying they were Racist1 or Racist2. But some of the responsibility is on the accusers too -- if you say "That Republican's a racist" with the implication of "a jerk" and then backtrack and change the meaning to "vulnerable to unconscious bias", then you're arguing in bad faith. Never mind that some laws and rules which were meant to protect people from Racist3's are in fact deployed against Racist2's.

To understand our civilisation, one must appreciate that the extended order resulted not from human design or intention but spontaneously: it arose from unintentionally conforming to certain traditional and largely moral practices, many of which men tend to dislike, whose significance they usually fail to understand, whose validity they cannot prove, and which have nonetheless fairly rapidly spread by means of an evolutionary selection — the comparative increase of population and wealth — of those groups that happened to follow them. The unwitting, reluctant, even painful adoption of these practices kept these groups together, increased their access to valuable information of all sorts, and enabled them to be 'fruitful, and multiply, and replenish the earth, and subdue it' (Genesis 1:28). This process is perhaps the least appreciated facet of human evolution.

The innkeeper looked up. "I have to admit I don't see the trouble," he said apologetically. "I've seen monsters, Bast. The Cthaeh falls short of that."

"That was the wrong word for me to use, Reshi," Bast admitted. "But I can't think of a better one. If there was a word that meant poisonous and hateful and contagious, I'd use that."

Bast drew a deep breath and leaned forward in his chair. "Reshi, the Cthaeh can see the future. Not in some vague, oracular way. It sees all the future. Clearly. Perfectly. Everything that can possibly come to pass, branching out endlessly from the current moment."

Kvothe raised an eyebrow. "It can, can it?"

"It can," Bast said gravely. "And it is purely, perfectly malicious. This isn't a problem for the most part, as it can't leave the tree. But when someone comes to visit..."

Kvothe's eyes went distant as he nodded to himself. "If it knows the future perfectly," he said slowly, "then it must know exactly how a person will react to anything it says."

Bast nodded. "And it is vicious, Reshi."

Kvothe continued in a musing tone. "That means anyone influenced by the Cthaeh would be like an arrow shot into the future."

"An arrow only hits on person, Reshi." Bast's dark eyes were hollow and hopeless. "Anyone influenced by the Cthaeh is like a plague ship sailing for a harbor." Bast pointed at the half-filled sheet Chronicler held in his lap. "If the Sithe knew that existed, they would spare no effort to destroy it. They would kill us for having heard what the Cthaeh said."

"Because anything carrying the Cthaeh's influence away from the tree..." Kvothe said, looking down at his hands. He sat silently for a long moment, nodding thoughtfully. "So a young man seeking his fortune goes to the Cthaeh and takes away a flower. The daughter of the king is deathly ill, and he takes the flower to heal her. They fall in love despite the fact that she's betrothed to the neighboring prince..."

Bast stared at Kvothe, watching blankly as he spoke.

"They attempt a daring moonlight escape," Kvothe continued. "But he falls from the rooftops and they're caught. The princess is married against her will and stabs the neighboring prince on their wedding night. The prince dies. Civil war. Fields burned and salted. Famine. Plague..."

"That's the story of the Fastingsway War," Bast said faintly.

A common mistake is to suppose that scientists are such admirable people that they can be safely entrusted with the ultimate responsibil­ity for guiding scientific research. In fact they are no more admirable than any other type of worker. Neither selection nor self-selection tor a scientific career is based on admirableness. Though the conventions and protocols of science enforce on scientists, in comparison to astrologers and English professors—and lawyers—a high degree of objec­tivity when they are doing science, it does not follow that such indi­viduals can be depended on to be objective policy analysts. That is a role for which they are not trained (but is anyone?) and that does not impose the constraints that science imposes.

It is neither desirable nor any longer effective to try bullying people into accepting the authority of science. Instead, all members of the educated public can be invited to participate in science, in order to experience the true nature and value of scientific inquiry. This does not mean listening to professional scientists tell condescending stories about how they have discovered wonderful things, which you should believe for reasons that are too difficult for you to understand in real depth and detail. Doing science ought to mean asking your own questions, making your own investigations, and drawing your own conclusions for your own reasons. Of course it will not be feasible to advance the "cutting edge" or "frontier" of modern science without first acquiring years of specialist training. However, the cutting edge is not all there is to science, nor is it necessarily the most valuable part of science. Questions that have been answered are still worth asking again, so you can understand for yourself how to arrive at the standard answers, and possibly discover new answers or recover forgotten answers that are valuable.

As in the Roman empire age, the theoretical concepts, taken out of the theories assigning their meaning and considered instead real objects, whose existence can be apparent only to the initiated people, are used to amaze the public. In physics courses the student (now unaware of the experimental basis of heliocentrism or of atomic theory, accepted on the sole basis of the authority principle) gets addicted to a complex and mysterious mythology, with orbitals undergoing hybridization, elusive quarks, voracious and disquieting black holes and a creating Big Bang: objects introduced, all of them, in theories totally unknown to him and having no understandable relation with any phenomenon he may have access to.

Now let's talk about efficient market theory, a wonderful economic doctrine that had a long vogue in spite of the experience of Berkshire Hathaway. In fact, one of the economists who won--he shared a Nobel Prize--and as he looked at Berkshire Hathaway year after year, which people would throw in his face as saying maybe the market isn't quite as efficient as you think, he said, "Well, it's a two-sigma event." And then he said we were a three-sigma event. And then he said we were a four-sigma event. And he finally got up to six sigmas--better to add a sigma than change a theory, just because the evidence comes in differently. [Laughter] And, of course, when this share of a Nobel Prize went into money management himself, he sank like a stone.

Man in Black: Inhale this, but do not touch.

Man in Black: What you do not smell is called iocane powder. It is odorless, tasteless, dissolves instantly in liquid, and is among the more deadlier poisons known to man.

[He puts the goblets behind his back and puts the poison into one of the goblets, then sets them down in front of him]

Man in Black: All right. Where is the poison? The battle of wits has begun. It ends when you decide and we both drink, and find out who is right... and who is dead.

[Vizzini stalls, then eventually chooses the glass in front of the man in black. They both drink, and Vizzini dies.]

Buttercup: And to think, all that time it was your cup that was poisoned.

Man in Black: They were both poisoned. I spent the last few years building up an immunity to iocane powder.

Suppose you know a golfer's score on day 1 and are asked to predict his score on day 2. You expect the golfer to retain the same level of talent on the second day, so your best guesses will be "above average" for the [better-scoring] player and "below average" for the [worse-scoring] player. Luck, of course, is a different matter. Since you have no way of predicting the golfers' luck on the second (or any) day, your best guess must be that it will be average, neither good nor bad. This means that in the absence of any other information, your best guess about the players' score on day 2 should not be a repeat of their performance on day 1. ...

The best predicted performance on day 2 is more moderate, closer to the average than the evidence on which it is based (the score on day 1). This is why the pattern is called regression to the mean. The more extreme the original score, the more regression we expect, because an extremely good score suggests a very lucky day. The regressive prediction is reasonable, but its accuracy is not guaranteed. A few of the golfers who scored 66 on day 1 will do even better on the second day, if their luck improves. Most will do worse, because their luck will no longer be above average.

Now let us go against the time arrow. Arrange the players by their performance on day 2 and look at their performance on day 1. You will find precisely the same pattern of regression to the mean. ... The fact that you observe regression when you predict an early event from a later event should help convince you that regression does not have a causal explanation.

For a hundred years or so, mathematical statisticians have been in love with the fact that the probability distribution of the sum of a very large number of very small random deviations almost always converges to a normal distribution. ... This infatuation tended to focus interest away from the fact that, for real data, the normal distribution is often rather poorly realized, if it is realized at all. We are often taught, rather casually, that, on average, measurements will fall within ±σ of the true value 68% of the time, within ±2σ 95% of the time, and within ±3σ 99.7% of the time. Extending this, one would expect a measurement to be off by ±20σ only one time out of 2 × 10^88. We all know that “glitches” are much more likely than that!

As far as I know, Robespierre, Lenin, Stalin, Mao, and Pol Pot were indeed unusually incorruptible, and I do hate them for this trait.

Why? Because when your goal is mass murder, corruption saves lives. Corruption leads you to take the easy way out, to compromise, to go along to get along. Corruption isn't a poison that makes everything worse. It's a diluting agent like water. Corruption makes good policies less good, and evil policies less evil.

I've read thousands of pages about Hitler. I can't recall the slightest hint of "corruption" on his record. Like Robespierre, Lenin, Stalin, Mao, and Pol Pot, Hitler was a sincerely murderous fanatic. The same goes for many of history's leading villains - see Eric Hoffer's classic The True Believer. Sincerity is so overrated. If only these self-righteous monsters had been corrupt hypocrites, millions of their victims could have bargained and bribed their way out of hell.

Chris Cillizza says that [...] the surge in the quantity of public polling available creates a confusing fog of numbers in which "partisans, who already live in a choose-your-own-political-reality world, can select the numbers that comply with their view of the race and pooh-pooh the data that suggest anything different."

That's true. But if you actually want to know what's happening in the race the increased poll volume makes it clearer not less clear. The sense that the polls are "all over the map" is the mistake. You need to think of each datapoint as having an associated probability distribution and then look at where they overlap. [...] The fact that we now have tons of polling that averages out to [a] conclusion means the scope for "sampling error" to throw us off is, at this point, tiny. One poll showing a lead of the current magnitude would leave us with a ton of uncertainty, but a bunch of polls makes the picture pretty clear.

I don't have any previous experience with this sort of thing, but judging from what I hear and read, I'm supposed to be asking why all this is happening, and why it's happening to me. Honestly, those questions are about the farthest thing from my mind.

Partly, that’s because they aren't hard questions. Why does our world have gravity? Why does the sun rise in the East? There are technical answers, but the metaphysical answer is simple: that’s how reality works. So too here. Only in the richest parts of the rich world of the twenty-first century could anyone entertain the thought that we should expect long, pain-free lives. Suffering and premature death (an odd phrase: what does it mean to call death "premature"?) are constant presences in the lives of most of the peoples of the Earth, and were routine parts of life for generations of our predecessors in this country—as they still are today, for those with their eyes open. Stage 4 cancers happen to middle-aged men and women, seemingly out of the blue, because that's how reality works.

As for why this is happening to me in particular, the implicit point of the question is an argument: I deserve better than this. There are two responses. First, I don't—I have no greater moral claim to be free from unwanted pain and loss than anyone else. Plenty of people more virtuous than I am suffer worse than I have, and some who don't seem virtuous at all skate through life with surprising ease. Welcome to the world. Once again, it seems to me that this claim arises from the incredibly unusual experience of a small class of wealthy professionals in the wealthiest parts of the world today. We think we live in a world governed by merit and moral desert. It isn't so. Luck, fortune, fate, providence—call it what you will, but whatever your preferred label, it has far more to do with the successes of the successful than what any of us deserves. Aristocracies of the past awarded wealth and position based on the accident of birth. Today's meritocracies award wealth and position based on the accident of being in the right place at the right time. The difference is smaller than we tend to think. Once you understand that, it’s hard to maintain a sense of grievance in the face of even the ugliest medical news. I’ve won more than my share of life's lotteries. It would seem churlish to rail at the unfairness of losing this one—if indeed I do lose it: which I may not.

The second response is simpler; it comes from the movie "Unforgiven." Gene Hackman is dying, and says to Clint Eastwood: "I don't deserve this. To die like this. I was building a house." Eastwood responds: "Deserve’s got nothing to do with it."

That gets it right, I think. It's a messed-up world, upside-down as often as it's rightside up. Bad things happen; future plans (that house Hackman was building) come to naught. Deserve's got nothing to do with it.

--William J. Stuntz, discussing his cancer diagnosis

Apologies for the length, but I wanted to include the full substantive point and hated to snip lines here and there. For what it's worth, Prof. Stuntz was a devout Christian, and the linked post went on to discuss his theological views on why "something deep within us expects, even demands moral order—in a world that shouts from the rooftops that no such order exists." Obviously I draw a different conclusion about this conflict, but I still respect that he could take such an unflinching view of how morally empty nature really is.
