At home there was a game that all the parents played with their children. It was called, What Did You See? Mara was about Dann’s age when she was first called into her father’s room one evening, where he sat in his big carved and coloured chair. He said to her, ‘And now we are going to play a game. What was the thing you liked best today?’

At first she chattered: ‘I played with my cousin . . . I was out with Shera in the garden . . . I made a stone house.’ And then he had said, ‘Tell me about the house.’ And she said, ‘I made a house of the stones that come from the river bed.’ And he said, ‘Now tell me about the stones.’ And she said, ‘They were mostly smooth stones, but some were sharp and had different shapes.’ ‘Tell me what the stones looked like, what colour they were, what did they feel like.’

And by the time the game ended she knew why some stones were smooth and some sharp and why they were different colours, some cracked, some so small they were almost sand. She knew how rivers rolled stones along and how some of them came from far away. She knew that the river had once been twice as wide as it was now. There seemed no end to what she knew, and yet her father had not told her much, but kept asking questions so she found the answers in herself. Like, ‘Why do you think some stones are smooth and round and some still sharp?’ And she thought and replied, ‘Some have been in the water a long time, rubbing against other stones, and some have only just been broken off bigger stones.’ Every evening, either her father or her mother called her in for What Did You See? She loved it. During the day, playing outside or with her toys, alone or with other children, she found herself thinking, Now notice what you are doing, so you can tell them tonight what you saw.

She had thought that the game did not change; but then one evening she was there when her little brother was first asked, What Did You See? and she knew just how much the game had changed for her. Because now it was not just What Did You See? but: What were you thinking? What made you think that? Are you sure that thought is true?

When she became seven, not long ago, and it was time for school, she was in a room with about twenty children – all from her family or from the Big Family – and the teacher, her mother’s sister, said, ‘And now the game: What Did You See?’

Most of the children had played the game since they were tiny; but some had not, and they were pitied by the ones that had, for they did not notice much and were often silent when the others said, ‘I saw . . .’, whatever it was. Mara was at first upset that this game played with so many at once was simpler, more babyish, than when she was with her parents. It was like going right back to the earliest stages of the game: ‘What did you see?’ ‘I saw a bird.’ ‘What kind of a bird?’ ‘It was black and white and had a yellow beak.’ ‘What shape of beak? Why do you think the beak is shaped like that?’

Then she saw what she was supposed to be understanding: Why did one child see this and the other that? Why did it sometimes need several children to see everything about a stone or a bird or a person?

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.

When confronting something which may be either a windmill or an evil giant, what question should you be asking?

There are some who ask, "If we do nothing, and that is an evil giant, can we afford to be wrong?" These people consider themselves to be brave and vigilant.

Some ask "If we attack it wrongly, can we afford to pay to replace a windmill?" These people consider themselves cautious and pragmatic.

Still others ask, "With the cost of being wrong so high in either case, shouldn't we always definitively answer the 'windmill vs. giant' question before we act?" And those people consider themselves objective and wise.

But only a tiny few will ask, "Isn't the fact that we're giving equal consideration to the existence of evil giants and windmills a warning sign of insanity in ourselves?"

It's hard to find out what these people consider themselves, because they never get invited to parties.

Don: "Up until the age of 25, I believed that 'invective' was a synonym for 'urine'."

BBC: "Why ever would you have thought that?"

Don: "During my childhood, I read many of the Edgar Rice Burroughs 'Tarzan' stories, and in those books, whenever a lion wandered into a clearing, the monkeys would leap into the trees and 'cast streams of invective upon the lion's head.'"

BBC: long pause "But, surely sir, you now know the meaning of the word."

Don: "Yes, but I do wonder under what other misapprehensions I continue to labour."

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. O that moral Science were in as fair a way of Improvement, that Men would cease to be Wolves to one another, and that human Beings would at length learn what they now improperly call Humanity!"

This time he covered a lot more ground and was willing to talk about the mundane details of presidential existence. “You have to exercise,” he said, for instance. “Or at some point you’ll just break down.” You also need to remove from your life the day-to-day problems that absorb most people for meaningful parts of their day. “You’ll see I wear only gray or blue suits,” he said. “I’m trying to pare down decisions. I don’t want to make decisions about what I’m eating or wearing. Because I have too many other decisions to make.” He mentioned research that shows the simple act of making decisions degrades one’s ability to make further decisions.

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.

A little long, but I don't see the possibility of a good cut:

“Other men were stronger, faster, younger, why was Syrio Forel the best? I will tell you now.” He touched the tip of his little finger lightly to his eyelid. “The seeing, the true seeing, that is the heart of it.

“Hear me. The ships of Braavos sail as far as the winds blow, to lands strange and wonderful, and when they return their captains fetch queer animals to the Sealord’s menagerie. Such animals as you have never seen, striped horses, great spotted things with necks as long as stilts, hairy mouse-pigs as big as cows, stinging manticores, tigers that carry their cubs in a pouch, terrible walking lizards with scythes for claws. Syrio Forel has seen these things.

“On the day I am speaking of, the first sword was newly dead, and the Sealord sent for me. Many bravos had come to him, and as many had been sent away, none could say why. When I came into his presence, he was seated, and in his lap was a fat yellow cat. He told me that one of his captains had brought the beast to him, from an island beyond the sunrise. ‘Have you ever seen her like?’ he asked of me.

“And to him I said, ‘Each night in the alleys of Braavos I see a thousand like him,’ and the Sealord laughed, and that day I was named the first sword.”

Arya screwed up her face. “I don’t understand.”

Syrio clicked his teeth together. “The cat was an ordinary cat, no more. The others expected a fabulous beast, so that is what they saw. How large it was, they said. It was no larger than any other cat, only fat from indolence, for the Sealord fed it from his own table. What curious small ears, they said. Its ears had been chewed away in kitten fights. And it was plainly a tomcat, yet the Sealord said ‘her,’ and that is what the others saw. Are you hearing?”

Arya thought about it. “You saw what was there.”

“Just so. Opening your eyes is all that is needing. The heart lies and the head plays tricks with us, but the eyes see true. Look with your eyes. Hear with your ears. Taste with your mouth. Smell with your nose. Feel with your skin. Then comes the thinking, afterward, and in that way knowing the truth.”

A long one:

. . . once upon a time men lived among the giants, who were like themselves but far more powerful, and these giants always had a supply of bread, fruit, milk, and all that was necessary to sustain life, which they must have acquired in ways that cost them little, for they would always give away their goods to whoever knew how to please them. And the giants would also carry them wherever they wanted to go, provided they asked in the proper way. So it came about that men never thought of working, nor of walking, nor of building wagons or ships; instead they became natural orators, and spent all of their time watching the giants, figuring out what would please or displease them, smiling at them or imploring them with tears in their eyes; or else simply pronouncing the necessary words, which had to be memorized exactly, though they had no understanding of the changes of humor that would come over the giants, their brusque refusals, or their sudden willingness. Now, if some man, in those days, had tried to get something for himself by his own industry, they would have laughed him to scorn; for the results of his labor would have been puny beside the immense provisions the giants had amassed; and besides with one false step the giants could easily have crushed those little beginnings of labor out of existence. That is why all human wisdom came down to knowing how to speak and how to persuade; and, rather than move things about with great effort, men chose to learn what words it would take to get one of the giants to do their moving. In short, their main business, or rather their only business, was to please, and above all not to displease, their incomprehensible masters, who seemed nevertheless to be charged with nourishing them and housing them and transporting them, and who eventually carried out their duties, provided they were prayed to. This kind of existence, in which men never knew whether they were the masters or the slaves, lasted for a long time, so that the habit of asking, of hoping, of counting on those stronger than themselves left indelible traces in human nature. . . . That is why, as if they were still waiting for the return of the giants, men do not forget to pray and make offerings, though no giant has ever shown himself . . .

The tautological emptiness of a Master's Wisdom is exemplified in the inherent stupidity of proverbs. Let us engage in a mental experiment by way of trying to construct proverbial wisdom out of the relationship between terrestrial life, its pleasures, and its Beyond. If ones says, "Forget about the afterlife, about the Elsewhere, seize the day, enjoy life fully here and now, it's the only life you've got!" it sounds deep. If one says exactly the opposite ("Do not get trapped in the illusory and vain pleasures of earthly life; money, power, and passions are all destined to vanish into thin air - think about eternity!"), it also sounds deep. If one combines the two sides ("Bring Eternity into your everyday life, live your life on this earth as if it is already permeated by Eternity!"), we get another profound thought. Needless to add, the same goes for it's inversion: "Do not try in vain to bring together Eternity and your terrestrial life, accept humbly that you are forever split between Heaven and Earth!" If, finally, one simply gets perplexed by all these reversals and claims: "Life is an enigma, do not try to penetrate its secrets, accept the beauty of its unfathomable mystery!" the result is, again, no less profound than its reversal: "Do not allow yourself to be distracted by false mysteries that just dissimulate the fact that, ultimately, life is very simple - it is what it is, it is simply here without reason and rhyme!" Needless to add that, by uniting mystery and simplicity, one again obtains a wisdom: "The ultimate, unfathomable mystery of life resides in its very simplicity, in the simple fact that there is life."

The Patrician took a sip of his beer. "I have told this to few people, gentlemen, and I suspect I never will again, but one day when I was a young boy on holiday in Uberwald I was walking along the bank of a stream when I saw a mother otter with her cubs. A very endearing sight, I'm sure you will agree, and even as I watched, the mother otter dived into the water and came up with a plump salmon, which she subdued and dragged onto a half-submerged log. As she ate it, while of course it was still alive, the body split and I remember to its day the sweet pinkness of its roes as they spilled out, much to the delight of the baby otters who scrambled over themselves to feed on the delicacy. One of nature's wonders, gentlemen: mother and children dining upon mother and children. And that's when I first learned about evil. It is built in to the very nature of the universe. Every world spins in pain. If there is any kind of supreme being, I told myself, it is up to all of us to become his moral superior."

...the discovery of computers and the thinking about computers has turned out to be extremely useful in many branches of human reasoning. For instance, we never really understood how lousy our understanding of languages was, the theory of grammar and all that stuff, until we tried to make a computer which would be able to understand language. We tried to learn a great deal about psychology by trying to understand how computers work. There are interesting philosophical questions about reasoning, and relationship, observation, and measurement and so on, which computers have stimulated us to think about anew, with new types of thinking. And all I was doing was hoping that the computer-type of thinking would give us some new ideas, if any are really needed.

On the difficulties of correctly fine-tuning your signaling:

I once expressed mild surprise at the presence of a garden gnome in an upper-middle-class garden …. The owner of the garden explained that the gnome was “ironic”. I asked him, with apologies for my ignorance, how one could tell that his garden gnome was supposed to be an ironic statement, as opposed to, you know, just a gnome. He rather sniffily replied that I only had to look at the rest of the garden for it to be obvious that the gnome was a tounge-in-cheek joke.

But surely, I persisted, garden gnomes are always something of a joke, in any garden—I mean, no-one actually takes them seriously or regards them as works of art. His response was rather rambling and confused (not to mention somewhat huffy), but the gist seemed to be that while the lower classes saw gnomes as intrinsically amusing, his gnome was amusing only because of its incongruous appearance in a “smart” garden. In other words, council-house gnomes were a joke, but his gnome was a joke about council-house tastes, effectively a joke about class….

The man’s reaction to my questions clearly defined him as upper-middle, rather than upper class. In fact, his pointing out that the gnome I had noticed was “ironic” had already demoted him by half a class from my original assessment. A genuine member of the upper classes would either have admitted to a passion for garden gnomes … or said something like “Ah yes, my gnome. I’m very fond of my gnome.” and left me to draw my own conclusions.

Most people don't know the basic scientific facts about happiness—about what brings it and what sustains it—and so they don't know how to use their money to acquire it. It is not surprising when wealthy people who know nothing about wine end up with cellars that aren't that much better stocked than their neighbors', and it should not be surprising when wealthy people who know nothing about happiness end up with lives that aren't that much happier than anyone else's. Money is an opportunity for happiness, but it is an opportunity that people routinely squander because the things they think will make them happy often don't.

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.

From Thomas Macaulay's 1848 History of England.

[W]e are under a deception similar to that which misleads the traveler in the Arabian desert. Beneath the caravan all is dry and bare; but far in advance, and far in the rear, is the semblance of refreshing waters... A similar illusion seems to haunt nations through every stage of the long progress from poverty and barbarism to the highest degrees of opulence and civilization. But if we resolutely chase the mirage backward, we shall find it recede before us into the regions of fabulous antiquity. It is now the fashion to place the golden age of England in times when noblemen were destitute of comforts the want of which would be intolerable to a modern footman, when farmers and shopkeepers breakfasted on loaves the very sight of which would raise a riot in a modern workhouse, when to have a clean shirt once a week was a privilege reserved for the higher class of gentry, when men died faster in the purest country air than they now die in the most pestilential lanes of our towns, and when men died faster in the lanes of our towns than they now die on the coast of Guiana.

.................................

We too shall in our turn be outstripped, and in our turn be envied. It may well be, in the twentieth century, that the peasant of Dorsetshire may think himself miserably paid with twenty shillings a week; that the carpenter at Greenwich may receive ten shillings a day; that laboring men may be as little used to dine without meat as they are now to eat rye bread; that sanitary police and medical discoveries may have added several more years to the average length of human life; that numerous comforts and luxuries which are now unknown, or confined to a few, may be within the reach of every diligent and thrifty workingman. And yet it may then be the mode to assert that the increase of wealth and the progress of science have benefited the few at the expense of the many, and to talk of the reign of Queen Victoria as the time when England was truly merry England, when all classes were bound together by brotherly sympathy, when the rich did not grind the faces of the poor, and when the poor did not envy the splendor of the rich.

Suppose we could somehow feed these reporters false information about market closes, but give them all the other news intact. Does anyone believe they would notice the anomaly, and not simply write that stocks were up (or down) on whatever good (or bad) news there was that day?

Sometimes you hear philosophers bemoaning the fact that philosophers tend not to form consensuses like certain other disciplines do (sciences in particular). But there is no great mystery to this. The sciences reward consensus-forming as long as certain procedures are followed: agreements through experimental verification, processes of peer review, etc. Philosophy has nothing like this. Philosophers are rewarded for coming up with creative reasons not to agree with other people. The whole thrust of professional philosophy is toward inventing ways to regard opposing arguments as failure, as long as those ways don't exhibit any obvious flaws. However much philosophers are interested in the truth, philosophy as a profession is not structured so as to converge on it; it is structured so as to have the maximal possible divergence that can be sustained given common conventions. We are not trained to find ways to come to agree with each other; we are trained to find ways to disagree with each other.

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.

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.

Unlike statements of fact, which require no further work on our part, lies must be continually protected from collisions with reality. When you tell the truth, you have nothing to keep track of. The world itself becomes your memory, and if questions arise, you can always point others back to it. You can even reconsider certain facts and honestly change your views. And you can openly discuss your confusion, conflicts, and doubts with all comers. In this way, a commitment to the truth is naturally purifying of error.

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.

One thing I have advocated, without much success, is that children be taught social rules (when they are ready) in exactly the same way they are taught and teach each other games. The point is not whether the rules are right or wrong. Are the rules of 5-card stud poker or hopscotch right or wrong? It's that we're playing a certain game here, and there are rules to this game just as in any other game. If you want to be in the game, then you have to learn how to play it. Different groups of people play different games (different rules = different game), so if you want to play in different groups, you have to learn the games they play. When you develop the levels of understanding above the rule level, you'll be able to understand all games, and be able to join in anywhere. You won't be stuck knowing how to play only one game.

My problem with selling this idea is that people tend to think that their game is the only right one. In fact, being told that they are playing a game with arbitrary rules is insulting or frightening. They want to believe that the rules they know are the ones that everyone ought to play by; they even set up systems of punishment and reward to make sure that nobody tries to play a different game. They turn the game into something that is deadly serious, and so my idea simply seems frivolous instead of liberating.

...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.

When people ask me what philosophy is, I say philosophy is what you do when you don't know what the right questions are yet. Once you get the questions right, then you go answer them, and that's typically not philosophy, that's one science or another. Anywhere in life where you find that people aren't quite sure what the right questions to ask are, what they're doing, then, is philosophy.

It was a good answer that was made by one who when they showed him hanging in a temple a picture of those who had paid their vows as having escaped shipwreck, and would have him say whether he did not now acknowledge the power of the gods,—‘Aye,' asked he again, ‘but where are they painted that were drowned after their vows?' And such is the way of all superstition, whether in astrology, dreams, omens, divine judgments, or the like; wherein men, having a delight in such vanities, mark the events where they are fulfilled, but where they fail, though this happens much oftener, neglect and pass them by.

What is more important in determining an (individual) organism's phenotype, its genes or its environment? Any developmental biologist knows that this is a meaningless question. Every aspect of an organism's phenotype is the joint product of its genes and its environment. To ask which is more important is like asking, Which is more important in determining the area of a rectangle, the length or the width? Which is more important in causing a car to run, the engine or the gasoline? Genes allow the environment to influence the development of phenotypes.

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.

'One day when I was a junior medical student, a very important Boston surgeon visited the school and delivered a great treatise on a large number of patients who had undergone successful operations for vascular reconstruction.

At the end of the lecture, a young student at the back of the room timidly asked, “Do you have any controls?” Well, the great surgeon drew himself up to his full height, hit the desk, and said, “Do you mean did I not operate on half the patients?” The hall grew very quiet then. The voice at the back of the room very hesitantly replied, “Yes, that’s what I had in mind.” Then the visitor’s fist really came down as he thundered, “Of course not. That would have doomed half of them to their death.”

God, it was quiet then, and one could scarcely hear the small voice ask, “Which half?”'

Should we then call the original replicator molecules 'living'? Who cares? I might say to you 'Darwin was the greatest man who has ever lived', and you might say 'No, Newton was', but I hope we would not prolong the argument. The point is that no conclusion of substance would be affected whichever way our argument was resolved. The facts of the lives and achievements of Newton and Darwin remain totally unchanged whether we label them 'great' or not. Similarly, the story of the replicator molecules probably happened something like the way I am telling it, regardless of whether we choose to call them 'living'. Human suffering has been caused because too many of us cannot grasp that words are only tools for our use, and that the mere presence in the dictionary of a word like 'living' does not mean it necessarily has to refer to something definite in the real world. Whether we call the early replicators living or not, they were the ancestors of life; they were our founding fathers.

But, there's another problem, and that is the fact that statistical and probabilistic thinking is a real damper on "intellectual" conversation. By this, I mean that there are many individuals who wish to make inferences about the world based on data which they observe, or offer up general typologies to frame a subsequent analysis. These individuals tend to be intelligent and have college degrees. Their discussion ranges over topics such as politics, culture and philosophy. But, introduction of questions about the moments about the distribution, or skepticism as to the representativeness of their sample, and so on, tends to have a chilling affect on the regular flow of discussion. While the average human being engages mostly in gossip and interpersonal conversation of some sort, the self-consciously intellectual interject a bit of data and abstraction (usually in the form of jargon or pithy quotations) into the mix. But the raison d'etre of the intellectual discussion is basically signaling and cuing; in other words, social display. No one really cares about the details and attempting to generate a rigorous model is really beside the point. Trying to push the N much beyond 2 or 3 (what you would see in a college essay format) will only elicit eye-rolling and irritation.

He informs Tony that he's never seen such a strong power crystal. Tony tells him it a piece of quartz. The buyer maintains it is an amazing power crystal and demands to know the price. Tony looks him over for a second, then says "If it's just a piece of quartz, it's $15. If it's a power crystal, it's $150. Which is is?" The buyer actually looked a bit sheepish as he said quietly "quartz", gave Tony his money and wandered off. I wonder if he thought he got the better of Tony.

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.

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.

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.

During the discussion of Pranknet on Slashdot about a month ago, I saw this comment. It reminded me of our discussions about Newcomb's problem and superrationality.

I also disagree that our society is based on mutual trust. Volumes and volumes of laws backed up by lawyers, police, and jails show otherwise.

That's called selection/observation bias. You're looking at only one side of the coin.

I've lived in countries where there's a lot less trust than here. The notion of returning an opened product to a store and getting a full refund is based on trust (yes, there's a profit incentive, and some people do screw the retailers [and the retailers their customers -- SB], but the system works overall). In some countries I've been to, this would be unfeasible: Almost everyone will try to exploit such a retailer.

When a storm knocks out the electricity and the traffic lights stop working, I've always seen everyone obeying the rules. I doubt it's because they're worried about cops. It's about trust that the other drivers will do likewise. Simply unworkable in other places I've lived in.

I've had neighbors whom I don't know receive UPS/FedEx packages for me. Again, trust. I don't think they're afraid of me beating them up.

There are loads of examples. Society, at least in the US, is fairly nice and a lot of that has to do with a common trust.

Which is why someone exploiting that trust is a despised person.

He who refuses to do arithmetic is doomed to talk nonsense.

-John McCarthy, on mainstream environmentalism.

As someone who regularly gets into arguments about this, I can say that he's definitely right; you wouldn't believe the amount of nonsense that can be disposed of simply by looking up the relevant numbers and doing a minute's worth of easy arithmetic.

For example, I've heard some people recently claiming that a combination of solar photovoltaics, electrolysis to produce hydrogen, and these new Bloom box fuel cells are cheaper than nuclear fission. Look up the costs of solar farms; about $3 per peak watt. Their average power output is less; we can very optimistically assume that they run at 20% of capacity on average. Efficiency losses from electrolysis and fuel cells are about 50%. Putting it all together, this would cost about $30 per watt of average power delivered. Not including the cost of the fuel cells.

A little googling will show that the total cost of building two new AP1000 reactors in Georgia is about $14 billion, and they average at least 93% of their peak power, and transmission line losses bring their average power delivered to about 1000 MW each. So their cost is about $7 per watt of average power delivered, or about 23% the cost of solar.

There's a lot of extremely harmful bullshit out there, and defeating most of it doesn't take any advanced techniques; it just takes a willingness to look up some relevant numbers and do a bit of arithmetic.

Sometimes, apparently rational self-interested strategies turn out (as in the prisoners' dilemma) to be self-defeating. This may look like a defeat for rationality, but it is not. Rationality is saved by its own open-endedness. If a strategy of following accepted rules of rationality is sometimes self-defeating, this is not the end. We revise the rules to take account of this, so producing a higher-order rationality strategy. This in turn may fail, but again we go up a level. At whatever level we fail, there is always the process of standing back and going up a further level.

"A Thinking Machine! Yes, we can now have our thinking done for us by machinery! The Editor of the Common School Advocate says—" On our way to Cincinnati, a few days since, we stopped over night where a gentleman from the city was introducing a machine which he said was designed to supercede the necessity and labor of thinking. It was highly and respectably recommended, by men too in high places, and is designed for a calculator, to save the trouble of all mathematical labor. By turning the machinery it produces correct results in addition, substraction, multiplication, and division, and the operator assured us that it was equally useful in fractions and the higher mathematics." The Editor thinks that such machines, by which the scholar may, by turning a crank, grind out the solution of a problem without the fatigue of mental application, would by its introduction into schools, do incalculable injury, But who knows that such machines when brought to greater perfection, may not think of a plan to remedy all their own defects and then grind out ideas beyond the ken of mortal mind!" --- The Primitive Expounder in 1847

One day, I was playing with an "express wagon," a little wagon with a railing around it, I noticed something about the way the ball moved. I went to my father and said, "Say, Pop, I noticed something. When I pull the wagon, the ball rolls to the back of the wagon. And when I'm pulling it along and I suddenly stop, the ball rolls to the front of the wagon. Why is that?"

"That, nobody knows," he said. "The general principle is that things which are moving tend to keep on moving, and things which are standing still tend to stand still, unless you push them hard. This tendency is called 'inertia,' but nobody knows why it's true." Now, that's a deep understanding. He didn't just give me the name.

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. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You'd be surprised how far that gets you.

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.

Economists essentially have a sophisticated lack of understanding of economics, especially macroeconomics. I know it sounds ridiculous. But the reason why I tell people they should study economics is not so they’ll know something at the end—because I don’t think we know much—but because we’re good at thinking. Economics teaches you to think things through. What you see a lot of times in economics is disdain for other's lack of thinking. You have to think about the ramifications of policies in the short run, the medium run, and the long run. Economists think they’re good at doing that, but they’re good at doing that in the sense that they can write down a model that will help them think about it—not in terms of empirically knowing what the answers are. And we have gotten so enamored of thinking things through that the fact that we don’t know anything needs to bother us more. So, yes, it’s true that the average guy on the street doesn’t understand economics, and it’s also true that we don’t understand economics. We just have a more sophisticated lack of understanding than the guy on the street.

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.

When I was young, I thought the act of getting older meant, year by year, getting more sophisticated, more hard, cool, and unpitying. Less innocent.

Maybe that was a childish idea of what getting older was about. Maybe adults, mature adults, get more innocent with time, not less. Because the word "innocent" does not mean "naive," it means "not guilty."

Children do small evils to each other, schoolyard fights and insults, not because their hearts are pure, but because their powers are small. Grown-ups have more power. Some of them do great evils with that power. But what about the ones who don't? Aren't they more innocent than children, not less?

In the wake of such suffering, there is no way to adequately explain the tragedy. Yet the seemingly random nature of the mass deaths has made them even harder for the survivors to understand.

"In a situation like this, it's only natural to want to assign blame," said Dr. Frederick MacDougal of the National Center for Infectious Diseases, who recently lost a third cousin to a degenerative nerve disorder. "But the disturbing thing about this case is that no one factor is at fault. People are dying for such a wide range of reasons--gunshot wounds, black-lung disease, falls down elevator shafts--that we have been unable to isolate any single element as the cause."

"No one simple explanation can encompass the enormous scope of this problem," MacDougal added. "And that's very difficult for most people to process psychologically."

[...]

Meanwhile, as the world continues to grapple with this seemingly unstoppable threat, the deaths--and the sorrow, fear and pain they have wrought--continue.

As Margaret Heller, a volunteer at a clinic in Baltimore put it, "We do everything we can. But for most of the people we try to help, the sad truth is it's only a matter of time."

They do have to go to school to learn written language, arithmetic, and science, because those bodies of knowledge and skill were invented too recently for any species-wide knack for them to have evolved.

News flash, dearies: there’s lots of areas of life that aren’t ‘science’ where people do tend to get a mite hung up on particulars of what is and is not, in fact, true. Like in bookkeeping. Like in criminal investigations. Like when they’re trying to establish where their spouse was last night.

Like, in fact, in most facets of life, hundreds of times a day, even if accounting isn’t your field and you’re not the accused at a criminal trial, and you’re not even married. Getting the facts right isn’t a concern of ‘science’, specifically. It’s a general concern of human beings. Getting reality right is, frequently, indeed, rather important if you wish to stay alive. It’s not a particularly academic question whether the car is or is not coming, when you cross the road. It’s the sort of thing one likes to get right.

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.

After the experiment has been done, if we've learned anything worth knowing at all, then hopefully we've learned why the experiment wasn't necessary to begin with -- why it wouldn't have made sense for the world to be any other way. But we're too dumb to figure it out ourselves! --Scott Aaronson

Nor of course must they ever be allowed to raise Aristotle’s question: whether “democratic behaviour” means the behaviour that democracies like or the behaviour that will preserve a democracy. For if they did, it could hardly fail to occur to them that these need not be the same.

(..)

Even if they don’t read Aristotle (that would be undemocratic) you would have thought the French Revolution would have taught them that the behaviour aristocrats naturally like is not the behaviour that preserves aristocracy. They might then have applied the same principle to all forms of government.

Just saw on reddit a perfect accidental metaphor: jakeredfield posted this in r/gaming:

For the people that have no played Portal yet, be warned, there may be spoilers up ahead for you.

So anyway, I am a huge fan of Portal, I love everything about the game. I bought it upon release and have played through it multiple times. My friends aren't as big of gamers as me so it took them some time to get their hands on Portal. My one friend didn't have a computer capable of running Portal so I let him play on mine.

I pulled up a chair besides him and eagerly watched him play then entire time. He loved the game. I expected him to. It's an awesome game. But here comes the WTF part...(SPOILERS AHEAD)

He go to the part at the last puzzle, right before GlaDOS tries to kill you in the fire. So then, my friend is like, "Oh, so it's one of those games where you die at the end. Haha, it was a good game." And then he immediately shuts it down. I just sat there. Shocked. In awe. I couldn't believe what I just saw. He turns to me and goes, "Good game, I'd play that again."

This is the part where I just hit him and yell, "IT WASN'T OVER YET!" He was so confused. He loaded it back up to that part and couldn't figure it out. I then pointed it out to him what he needed to do from there. He eventually fully finished the game.

Imagine what would have happened if I wasn't there? How many other people do you think only experienced the game up to this part, because they didn't have someone tell them?

What makes it even more perfect is this reply by Aleitheo:

So rather than try to see if he could live or even just die in the fire he turned off the game before he even saw the "ending"?

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.

Keith E. Stanovich, How to Think Straight About Psychology, 10th ed. (2013), 14.

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.

The mere fact that it is possible to frame a question does not make it legitimate or sensible to do so. There are many things about which you can ask, "What is its temperature?" or "What color is it?" but you may not ask the temperature question or the color question of, say, jealousy or prayer. Similarly, you are right to ask the "Why" question of a bicycle's mudguards or the Kariba Dam, but at the very least you have no right to assume that the "Why" question deserves an answer when posed about a boulder, a misfortune, Mt.

A fable:

In Persia many centuries ago, the Sufi mullah or holy man Nasruddin was arrested after preaching in the great square in front of the Shah's palace. The local clerics had objected to Mullah Nasruddin's unorthodox teachings, and had demanded his arrest and execution as a heretic. Dragged by palace guards to the Shah's throne room, he was sentenced immediately to death.

As he was being taken away, however, Nasruddin cried out to the Shah: "O great Shah, if you spare me, I promise that within a year I will teach your favourite horse to sing!"

The Shah knew that Sufis often told the most outrageous fables, which sounded blasphemous to many Muslims but which were nevertheless intended as lessons to those who would learn. Thus he had been tempted to be merciful, anyway, despite the demands of his own religious advisors. Now, admiring the audacity of the old man, and being a gambler at heart, he accepted his proposal.

The next morning, Nasruddin was in the royal stable, singing hymns to the Shah's horse, a magnificent white stallion. The animal, however, was more interested in his oats and hay, and ignored him. The grooms and stablehands all shook their heads and laughed at him. "You old fool", said one. "What have you accomplished by promising to teach the Shah's horse to sing? You are bound to fail, and when you do, the Shah will not only have you killed - you'll be tortured as well, for mocking him!"

Nasruddin turned to the groom and replied: "On the contrary, I have indeed accomplished much. Remember, I have been granted another year of life, which is precious in itself. Furthermore, in that time, many things can happen. I might escape. Or I might die anyway. Or the Shah might die, and his successor will likely release all prisoners to celebrate his accession to the throne".

"Or...". Suddenly, Nasruddin smiled. "Or, perhaps, the horse will learn to sing".

The original source of this fable seems to be lost to time. This version was written by Idries Shah.

As they're telling me the conditions of the theorem, I construct something which fits all the conditions. You know, you have a set (one ball) – disjoint (two balls). Then the balls turn colors, grow hairs, or whatever, in my head as they put more conditions on. Finally they state the theorem, which is some dumb thing about the ball which isn't true for my hairy green ball thing, so I say, 'False!'

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.

I have met people who exaggerate the differences [between the morality of different cultures], because they have not distinguished between differences of morality and differences of belief about facts. For example, one man said to me, "Three hundred years ago people in England were putting witches to death. Was that what you call the Rule of Human Nature or Right Conduct?" But surely the reason we do not execute witches is that we do not believe there are such things. If we did-if we really thought that there were people going about who had sold themselves to the devil and received supernatural powers from him in return and were using these powers to kill their neighbours or drive them mad or bring bad weather, surely we would all agree that if anyone deserved the death penalty, then these filthy quislings did. There is no difference of moral principle here: the difference is simply about matter of fact. It may be a great advance in knowledge not to believe in witches: there is no moral advance in not executing them when you do not think they are there. You would not call a man humane for ceasing to set mousetraps if he did so because he believed there were no mice in the house.

In the autumn of 1939, Ludwig Wittgenstein and his young Cambridge student and friend Norman Malcolm were walking along the river when they saw a newspaper vendor's sign announcing that the Germans had accused the British government of instigating a recent attempt to assassinate Hitler. When Wittgenstein remarked that it wouldn't surprise him at all if it were true, Malcolm retorted that it was impossible because "the British were too civilized and decent to attempt anything so underhand, and . . . such an act was incompatible with the British 'national character'." Wittgenstein was furious. Some five years later, he wrote to Malcolm:

"Whenever I thought of you I couldn't help thinking of a particular incident which seemed to me very important. . . . you made a remark about 'national character' that shocked me by its primitiveness. I then thought: what is the use of studying philosophy if all that it does for you is to enable you to talk with some plausibility about some abstruse questions of logic, etc., if it does not improve your thinking about the important questions of everyday life, if it does not make you more conscientious than any . . . journalist in the use of the DANGEROUS phrases such people use for their own ends."

--Marjorie Perloff, Wittgensteins Ladder; apparently of the many attempts, the one referred to did not actually have British backing, although some did eg. the Oster Conspiracy or Operation Foxley.

(This is the full and original quote; the emphasis is on the section which is usually paraphrased as, "What is the use of studying philosophy if all that it does for you is to enable you to talk with some plausibility about some abstruse questions of logic...if it does not improve your thinking about the important questions of everyday life?")

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 helps to stop worrying about what you are and concentrate on what you do. If you think of a poet as a person with some special qualifications that come by nature (or divine favor), you are likely to make one of two mistakes about yourself. If you think you've got what it takes, you may fail to learn what you need to know in order to use whatever qualities you may have. On the other hand, if you think you do not have what it takes, you may give up too easily, thinking it is useless to try. A poet is someone - you, me, anyone - who writes poems. That question out of the way, now we can learn to write poems better.

"Lottery tickets should not be free. In such purely random and independent events as the lottery, the probability of having a winning number depends directly on the number of tickets you have purchased. When one evaluates the outcome of a scientific work, attention must be given not only to the potential interest of the ‘significant’ outcomes but also to the number of ‘lottery tickets’ the authors have ‘bought’. Those having many have a much higher chance of ‘winning a lottery prize’ than of getting a meaningful scientific result. It would be unfair not to distinguish between significant results of well-planned, powerful, sharply focused studies, and those from ‘fishing expeditions’ with a much higher probability of catching an old truck tyre than of a really big fish."

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.

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.

But my response to this was not to draw on something called will power, to insult or threaten myself, but to take a longer look at my life, to extend my vision, to think about the whole of my experience, to reconnect present and future, and quite specifically, to ask myself, "Do you like playing the cello or not? Would you like to play it better or not?" When I put the matter this way I could see that I enjoyed playing the cello more than I enjoyed staying in bed. So I got up. If, as sometimes happened or happens, I do stay in bed, not sleeping, not really thinking, but just not getting up, it is not because will power is weak but because I have temporarily become disconnected, so to speak, from the wholeness of my life. I am living in that Now that some people pursue so frantically, that gets harder to find the harder we look for it.

To sum up: it is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence.

If a man, holding a belief which he was taught in childhood or persuaded of afterwards, keeps down and pushes away any doubts which arise about it in his mind, purposely avoids the reading of books and the company of men that call into question or discuss it, and regards as impious those questions which cannot easily be asked without disturbing it--the life of that man is one long sin against mankind.

... "But," says one, "I am a busy man; I have no time for the long course of study which would be necessary to make me in any degree a competent judge of certain questions, or even able to understand the nature of the arguments."

Then he should have no time to believe.

One of the most serious problems with modern "management" is that the incentives are all wrong. Imagine that I hire a programmer and pay him by the line of code. This idea has been so thoroughly debunked that it is nearly impossible to write out the consequences without sounding cliché. Yet it happens all the time: Companies promote "Architects" who are evaluated by the weight of their "architecture." The result is stultifying and demoralizing. The architect does not work to facilitate the programmer's work, he works to produce evidence of his contribution in the form of frameworks, standards, and software process.

So, how are most managers evaluated? By the amount of "managing" they do, as measured by the amount of process they impose on their team. Evaluating a manager by the amount of managing they do is exactly the same thing as evaluating a programmer by the amount of code they write. And it produces results like you describe, where the manager works to produce evidence of their management in the form of processes and decisions from the top down, rather than facilitating the work actually being done.

Don't you feel in your heart that these contradictions do not really contradict: that there is a cosmos that contains them all? The soul goes round upon a wheel of stars and all things return; perhaps Strake and I have striven in many shapes, beast against beast and bird against bird, and perhaps we shall strive for ever. But since we seek and need each other, even that eternal hatred is an eternal love. Good and evil go round in a wheel that is one thing and not many. Do you not realize in your heart, do you not believe behind all your beliefs, that there is but one reality and we are its shadows; and that all things are but aspects of one thing: a centre where men melt into Man and Man into God?'

People can learn to look you in the eyes even when they're lying to you. But it's kind of like a fake smile; there are involuntary muscles up there. If you know what you're looking for, you can still tell. But what does it mean if they're looking you in the eyes and they mean it? It means that, at least in that moment, they're doing what they really believe is right. That's the definition of integrity.

That part is easy. That's not the surprising thing.

The surprising thing, to me, was that someone can have integrity and still be completely evil. It's kind of obvious in retrospect; the super-villain in an action movie can always look the hero in the eye, and he always does, just to prove it. He has integrity. Evil with integrity is more respectable, somehow, than plain evil. All it takes to have integrity is to do what you think is right, no matter how stupid that may be.

...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.

He did not observe that with all his efforts he made no advance—meeting no resistance that might, as it were, serve as a support upon which he could take a stand, to which he could apply his powers, and so set his understanding in motion.

Rule I

We are to admit no more causes of natural things than such as are both true and sufficient to explain their appearances.

To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes.

Rule II

Therefore to the same natural effects we must, as far as possible, assign the same causes.

As to respiration in a man and in a beast; the descent of stones in Europe and in America; the light of our culinary fire and of the sun; the reflection of light in the earth, and in the planets.

Rule III

The qualities of bodies, which admit neither intensification nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever.

For since the qualities of bodies are only known to us by experiments, we are to hold for universal all such as universally agree with experiments; and such as are not liable to diminution can never be quite taken away. We are certainly not to relinquish the evidence for the sake of dreams and vain fictions of our own devising; nor are we to recede from the analogy of Nature, which is wont to be simple, and always consonant to itself. . .

Rule IV

In experimental philosophy we are to look upon propositions inferred by general induction from phenomena as accurately or very nearly true, notwithstanding any contrary hypotheses that may be imagined, till such time as other phenomena occur, by which they may either be made more accurate, or liable to exceptions.

This rule we must follow, that the argument of induction may not be evaded by hypotheses.

From desert cliff and mountaintop we trace the wide design,

Strike-slip fault and overthrust and syn and anticline...

We gaze upon creation where erosion makes it known,

And count the countless aeons in the banding of the stone.

Odd, long-vanished creatures and their tracks shells are found;

Where truth has left its sketches on the slate below the ground.

The patient stone can speak, if we but listen when it talks.

Humans wrote the Bible; God wrote the rocks.

There are those who name the stars, who watch the sky by night,

Seeking out the darkest place, to better see the light.

Long ago, when torture broke the remnant of his will,

Galileo recanted, but the Earth is moving still.

High above the mountaintops, where only distance bars,

The truth has left its footprints in the dust between the stars.

We may watch and study or may shudder and deny,

Humans wrote the Bible; God wrote the sky.

By stem and root and branch we trace, by feather, fang and fur,

How the living things that are descend from things that were.

The moss, the kelp, the zebrafish, the very mice and flies,

These tiny, humble, wordless things--how shall they tell us lies?

We are kin to beasts; no other answer can we bring.

The truth has left its fingerprints on every living thing.

Remember, should you have to choose between them in the strife,

Humans wrote the Bible; God wrote life.

And we who listen to the stars, or walk the dusty grade,

Or break the very atoms down to see how they are made,

Or study cells, or living things, seek truth with open hand.

The profoundest act of worship is to try to understand.

Deep in flower and in flesh, in star and soil and seed,

The truth has left its living word for anyone to read.

So turn and look where best you think the story is unfurled.

Humans wrote the Bible; God wrote the world.

The Three Virtues of a Programmer:

  • Laziness - The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful, and document what you wrote so you don't have to answer so many questions about it.

  • Impatience - The anger you feel when the computer is being lazy. This makes you write programs that don't just react to your needs, but actually anticipate them. Or at least pretend to.

  • Hubris - Excessive pride, the sort of thing Zeus zaps you for. Also the quality that makes you write (and maintain) programs that other people won't want to say bad things about.

Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is "wishful thinking." You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant — but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must first find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error.

... People usually don't know why they vote for the candidates they choose to vote for, and are not particularly good at assessing how something influenced that vote -- let alone how some hypothetical future event would influence them.

...if you ask voters, it turns out that some will tell you that they would be more likely, and a somewhat larger number will tell you that they'll be less likely, to vote for someone with a Trump endorsement. 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.

(In a thread where people were asked whether or not they had a religious experience of "feeling God"):

I had something similar to feeling God, I suppose, except it was in essence the exact opposite. I was in a forest one summer, and I looked up at the sunlight shining through the leaves, and suddenly it felt like I could see each and every individual leaf in the forest and trace the path of each photon that poured through them, and I remember thinking over and over, in stunned amazement, "the world is sufficient. The world is sufficient."

I'd never thought much about religion before that, but that experience made me realize that the material world was entire orders of magnitude more beautiful than any of the tawdry religious fantasies people came up with, and it felt unspeakably tragic that anyone would ever reject this, our most incredible universe, for spiritual pipe-dreams. In a way, you might say I felt the lack of god, and it felt like glory.

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.

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.

I've linked to a quote from Daniel Ellsberg at Overcoming Bias, but it seemed relevant enough here to excerpt the bits that caught my eye:

First, you'll be exhilarated by some of this new information, and by having it all — so much! incredible! — suddenly available to you. But second, almost as fast, you will feel like a fool for having studied, written, talked about these subjects, criticized and analyzed decisions made by presidents for years without having known of the existence of all this information, which presidents and others had and you didn't, and which must have influenced their decisions in ways you couldn't even guess

[...]

you will forget there ever was a time when you didn't have it, and you'll be aware only of the fact that you have it now and most others don't....and that all those other people are fools

[...]

you'll eventually become aware of the limitations of this information [...] But that takes a while to learn. In the meantime it will have become very hard for you to learn from anybody who doesn't have these clearances. Because you'll be thinking as you listen to them: 'What would this man be telling me if he knew what I know? Would he be giving me the same advice, or would it totally change his predictions and recommendations?' And that mental exercise is so torturous that after a while you give it up and just stop listening.

[...]

You will deal with a person who doesn't have those clearances only from the point of view of what you want him to believe and what impression you want him to go away with, since you'll have to lie carefully to him about what you know. In effect, you will have to manipulate him. You'll give up trying to assess what he has to say. The danger is, you'll become something like a moron. You'll become incapable of learning from most people in the world, no matter how much experience they may have in their particular areas that may be much greater than yours.

One of my mentors once gave me a list of obvious things to check when stuff doesn't work. Funny, years later I still need this list:

  1. It worked. No one touched it but you. It doesn't work. It's probably something you did.

  2. It worked. You made one change. It doesn't work. It's probably the change you made.

  3. It worked. You promoted it. It doesn't work. Your testing environment probably isn't the same as your production environment.

  4. It worked for these 10 cases. It didn't work for the 11th case. It was probably never right in the first place.

  5. It worked perfectly for 10 years. Today it didn't work. Something probably changed.

When I was halfway through my Ph.D. I formulated a hypothesis: The proximate challenge that keeps you from graduating is that you have to write a thesis. But the ultimate challenge to getting your Ph.D. is this: You somehow have to learn to understand, deep down, that all your romantic notions about the Ph.D. are bunk, that you will be exactly the same person on the day after you get it that you were the day before, and that you need to stop waiting for the day when you feel like a god and just write something down and get on with life.

It may take you years to accept this, and it may drive you to drink, but after you get to that point you can graduate.

Only then will you be able to live with the fact that your thesis looks like crap to you. Your thesis will always look like crap to you. Either you will have figured out absolutely everything and your thesis will look incredibly boring to you, because you've moved on, or -- vastly more likely -- your thesis will look woefully incomplete because, geez, there is so much that you couldn't figure out, and you're just so stupid!

Or, most likely of all, you will think both of these things at the same time.

Similarly: Being the world's foremost expert on a particular scientific problem is a lot less exciting in real life than it seems in the movies. In fact, being on the frontier of science feels like being totally, hopelessly lost and confused. Why this came as a surprise to me I'll never know.

In prose, the worst thing one can do with words is surrender to them. When you think of a concrete object, you think wordlessly, and then, if you want to describe the thing you have been visualizing you probably hunt about until you find the exact words that seem to fit it. When you think of something abstract you are more inclined to use words from the start, and unless you make a conscious effort to prevent it, the existing dialect will come rushing in and do the job for you, at the expense of blurring or even changing your meaning. Probably it is better to put off using words as long as possible and get one's meaning as clear as one can through pictures and sensations.

Now I view it as perhaps the single most important piece of information that a forecaster provides. When we publish a forecast on FiveThirtyEight, I go to great lengths to document the uncertainty attached to it, even if the uncertainty is sufficiently large that the forecast won’t make for punchy headlines.

In the early 1970's it cost $7 to buy a share in [Warren Buffett's] company, and that same share is worth $4,900 today... That makes Buffett a wonderful investor. What makes him the greatest investor of all time is that during a certain period when he thought stocks were grossly overpriced, he sold everything and returned all the money to his partners at a sizable profit to them. The voluntary returning of money that others would gladly pay you to continue to manage is, in my experience, unique in the history of finance.

Some environments are worse than irregular. Robin Hogarth described "wicked" environments, in which professionals are likely to learn the wrong lessons from experience. He borrows from Lewis Thomas the example of a physician in the early twentieth century who often had intuitions about patients who were about to develop typhoid. 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.

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?

Moral language persuades best when opinions are not yet formed, which is why writers of children’s literature can get away with saying things like, “Mr. Billings was an awful, horrible man with a heart of stone.” This sounds like a line from a children’s book because it employs persuasive methods that, though appropriate for children, would insult the intelligence of most adult readers.

Most moral discourse is the conversational equivalent of children’s literature. Disputants speak to one another—or, rather, at one another—as if their interlocutors failed to pay adequate attention on the day elementary morality was explained. Unaware of the projective nature of value, they marvel at their opponents’ blindness, their utter failure to see what is so perfectly obvious. Not knowing what else to do, they scold their opponents as if they were children, and scold them as if they were belligerent children when they fail to respond the first time.

What to do about this? Take a cue from good writers. Stick to the facts. Keep evaluative language to a minimum, and get rid of the most overtly judgmental, moralistic language.

'One day, Korzybski was giving a lecture to a group of students, and he interrupted the lesson suddenly in order to retrieve a packet of biscuits, wrapped in white paper, from his briefcase. He muttered that he just had to eat something, and he asked the students on the seats in the front row, if they would also like a biscuit. A few students took a biscuit.

"Nice biscuit, don't you think," said Korzybski, while he took a 2nd one. The students were chewing vigorously. Then he tore the white paper from the biscuits, in order to reveal the original packaging. On it was a big picture of a dog's head and the words "Dog Cookies."

The students looked at the package, and were shocked. Two of them wanted to vomit, put their hands in front of their mouths, and ran out of the lecture hall to the toilet.

"You see," Korzybski remarked, "I have just demonstrated that people don't just eat food, but also words, and that the taste of the former is often outdone by the taste of the latter."'

I think of this as a rationalist parable and not so much a quote. It has a lot of personal resonance since I often had dog biscuits with my tea when I was younger.

On the same theme as the previous one:

I've begun worshipping the sun for a number of reasons. First of all, unlike some other gods I could mention, I can see the sun. It's there for me every day. And the things it brings me are quite apparent all the time: heat, light, food, a lovely day. There is no mystery, no one asks for money, I don't have to dress up, and there is no boring pageantry. And interestingly enough, I have found that the prayers I offer to the sun and the prayers I formerly offered to "God" are all answered at about the same 50-percent rate.

The classical theorists resemble Euclidean geometers in a non-Euclidean world who, discovering that in experience straight lines apparently parallel often meet, rebuke the lines for not keeping straight as the only remedy for the unfortunate collisions which are occurring. Yet, in truth, there is no remedy except to throw over the axiom of parallels and to work out a non-Euclidean geometry.

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.

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."

Once again, we are saddled with a Stone Age moral psychology that is appropriate to life in small, homogeneous communities in which all members share roughly the same moral outlook. Our minds trick us into thinking that we are absolutely right and that they are absolutely wrong because, once upon a time, this was a useful way to think. It is no more, though it remains natural as ever. We love our respective moral senses. They are as much a part of us as anything. But if we are to live together in the world we have created for ourselves, so unlike the one in which our ancestors evolved, we must know when to trust our moral senses and when to ignore them.

As a rule, people judged themselves according to their intentions and others according to results. In study after study, individuals ranked themselves as more charitable, more compassionate, more conscientious than others, not because they in fact were - but because they wanted to be these things and were almost entirely blind to the fact that others wanted the same. Intentions were all important when it came to self-judgement, and pretty much irrelevant when it came to judging others. The only exceptions, it turned out, were loved ones.

That was what it meant to be a 'significant' other: to be included in the circle of delusions that everyone used to exempt themselves.

Idealists of all schools, aristocrats and bourgeois, theologians and physicians, politicians and moralists, religionists, philosophers, or poets, not forgetting the liberal economists - unbounded worshippers of the ideal, as we know - are much offended when told that man, with his magnificent intelligence, his sublime ideas, and his boundless aspirations, is, like all else existing in the world, nothing but matter, only a product of vile matter.

We may answer that the matter of which materialists speak, matter spontaneously and eternally mobile, active, productive, matter chemically or organically determined and manifested by the properties or forces, mechanical, physical, animal, and intelligent, which necessarily belong to it - that this matter has nothing in common with the vile matter of the idealists. The latter, a product of their false abstraction, is indeed a stupid, inanimate, immobile thing, incapable of giving birth to the smallest product, a caput mortuum, an ugly fancy in contrast to the beautiful fancy which they call God; as the opposite of this supreme being, matter, their matter, stripped by that constitutes its real nature, necessarily represents supreme nothingness.

From Wintersmith, on the ability to notice confusion rather than rationalizing:

"And now I shall tell you something vitally important. It is the secret of my long life.”

Ah, thought Tiffany, and she leaned forward.

“The important thing,” said Miss Treason, “is to stay the passage of the wind. You should avoid rumbustious fruits and vegetables. Beans are the worst, take it from me.”

“I don’t think I understand—” Tiffany began.

“Try not to fart, in a nutshell.”

“In a nutshell I imagine it would be pretty unpleasant!” said Tiffany nervously. She couldn’t believe she was being told this.

“This is no joking matter,” said Miss Treason. “The human body only has so much air in it. You have to make it last. One plate of beans can take a year off your life. I have avoided rumbustiousness all my days. I am an old person and that means what I say is wisdom!” She gave the bewildered Tiffany a stern look. “Do you understand, child?”

Tiffany’s mind raced. Everything is a test! “No,” she said. “I’m not a child and that’s nonsense, not wisdom!”

The stern look cracked into a smile. “Yes,” said Miss Treason. “Total gibberish. But you’ve got to admit it’s a corker, all the same, right? You definitely believed it, just for a moment? The villagers did last year. You should have seen the way they walked about for a few weeks! The strained looks on their faces quite cheered me up!"

About the intersection of math and politics through the mind of a child, Bob Murphy relates this story about his six-year-old son Clark:

Clark: Daddy why can’t there be a biggest number?

Bob: Because no matter how big a number is, there is always a bigger number.

Clark (puzzled): Why?

Bob: OK, let’s say a guy comes up to me and says, “Hey, I know the biggest number!” Then I would say, “Oh yeah, what is it?” And the guy would tell me, “It’s a billion billion.” But then I would just add 1 to it, and say, “A ha, a billion billion and 1 is a bigger number. So you made a mistake when you said you thought of the biggest number.”

Clark (after a pause): What guy are you talking about?

Bob: Just any guy. I’m saying, if anybody tries to think of the biggest number, I’ll always be able to do that trick–where I add 1 to it–so they can’t do it. They’ll always lose.

Clark: What if a girl asks you?

[I ran through the same thing with a girl asking me...]

Clark: OK I want to tell the story!

Bob: Sure go ahead.

Clark: So what if a guy came up to me and said, “Hey Clark, I know the biggest number! It’s 100 billion!” Then I would say, “No, 100 billion and 1 is bigger! You’re wrong!”

Bob: Right, good job. So he didn’t really think of the biggest number after all, did he?

Clark: No.

Bob: And you can always do that.

Clark: OK let me tell it again with Sam [name possibly changed--a kid from his class].

Bob: OK.

Clark: So what if Sam came up to me and said, “Hey Clark, I know the biggest number. It’s 50 googol.” But I would say, “No Sam you’re wrong! 50 googol and 1 is bigger!” But Sam gets mad so he would start shouting and say, “I DID TOO THINK OF THE BIGGEST NUMBER CLARK!!”

And I know we're not supposed to quote ourselves, but you rarely get an opportunity to use a line like this:

I guess you already tried explaining to Clark that the cardinality of the natural numbers is invariant under transformations of largest number proponent?

Ralph Hull made a reasonable living as a magician milking a card trick he called "The Tuned Deck"...Hull enjoyed subjecting himself to the scrutiny of colleagues who attempted to eliminate, one by one, various explanations by depriving him of the ability to perform a particular sleight of hand. But the real trick was over before it had even begun, for the magic was not in clever fingers but in a clever name. The blatantly singular referent cried out for a blatantly singular explanation, when in reality The Tuned Deck was not one trick but many. The search for a single explanation is what kept this multiply determined illusion so long a mystery.

Writers of all stripes enjoy engaging in the most cynical readings of human behavior because they think it makes them appear hyper-rational. But in fact here is a perfect example of how trying to achieve that makes you irrational. Human emotion is real. It is an observable phenomenon. It observably influences behavior. Therefore to fail to account for it when discussing coupling and relationships is the opposite of cold rationality; it is in fact a failure of empiricism.

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.

It may be of course that savages put food on a dead man because they think that a dead man can eat, or weapons with a dead man because they think a dead man can fight. 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. We do not understand, it is true, the emotion that makes us think it is obvious and natural; but that is because, like all the important emotions of human existence it is essentially irrational.

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.

In the way that skepticism is sometimes applied to issues of public concern, there is a tendency to belittle, to condescend, to ignore the fact that, deluded or not, supporters of superstition and pseudoscience are human beings with real feelings, who, like the skeptics, are trying to figure out how the world works and what our role in it might be.

Practically anything can go faster than Disc light, which is lazy and tame, unlike ordinary light. The only thing known to go faster than ordinary light is monarchy, according to the philosopher Ly Tin Wheedle. He reasoned like this: you can't have more than one king, and tradition demands that there is no gap between kings, so when a king dies the succession must therefore pass to the heir instantaneously. Presumably, he said, there must be some elementary particles—kingons, or possibly queons—that do this job, but of course succession sometimes fails if, in mid-flight, they strike an anti-particle, or republicon. His ambitious plans to use his discovery to send messages, involving the careful torturing of a small king in order to modulate the signal, were never fully expounded because, at that point, the bar closed.

David Hume was right to predict that superstition would survive for hundreds of years after his death, but how could he have anticipated that his own work would inspire Kant to invent a whole new package of superstitions? Or that the incoherent system of Marx would move vast populations to engineer their own ruin? Or that the infantile rantings of the author of Mein Kampf would be capable of bringing the whole world to war?

Perhaps we will one day succeed in immunizing our societies against such bouts of collective idiocy by establishing a social contract in which each child is systematically instructed in Humean skepticism. Such a new Emile would learn about the psychological weaknesses to which Homo sapiens is prey, and so would understand the wisdom of treating all authorities - political leaders and social role-models, academics and teachers, philosophers and prophets, poets and pop stars - as so many potential rogues and knoves, each out to exploit the universal human hunger for social status. He would therefore appreciate the necessity of doing all of his own thinking for himself. He would understand why and when to trust his neighbors. Above all, he would waste no time yearning for utopias that are incompatible with human nature.

The science fiction writer Arthur C. Clarke remarked that "any sufficiently advanced technology is indistinguishable from magic". Clarke was referring to the fantastic inventions we might discover in the future or in our travels to advanced civilizations. However, the insight also applies to self-perception. When we turn our attention to our own minds, we are faced with trying to understand an unimaginably advanced technology. We can't possibly know (let alone keep track of) the tremendous number of mechanical influences on our behavior because we inhabit an extraordinarily complicated machine. So we develop a shorthand, a belief in the causal efficacy of our conscious thoughts. We believe in the magic of our own causal agency.

On practical questions of urgent importance we must make up our minds one way or the other even when we know that the evidence is incomplete. To refuse to make up our minds is equivalent to deciding to leave things as they are (which is just as likely as any other to be the wrong solution).

Some years ago I was trying to decide whether or not to move to Harvard from Stanford. I had bored my friends silly with endless discussion. Finally, one of them said, “You’re one of our leading decision theorists. Maybe you should make a list of the costs and benefits and try to roughly calculate your expected utility.” Without thinking, I blurted out, “Come on, Sandy, this is serious.”

Most people are theists not because they were "reasoned into" believing in God, but because they applied Occam's razor at too early an age. Their simplest explanation for the reason that their parents, not to mention everyone else in the world, believed in God, was that God actually existed. The same could be said for, say, Australia.

“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.”

The demons told me that there is a hell for the sentimental and the pedantic. They are abandoned in an endless palace, more empty than full, and windowless. The condemned walk about as if searching for something, and, as we might expect, they soon begin to say that the greatest torment consists in not participating in the vision of God, that moral suffering is worse than physical suffering, and so on. Then the demons hurl them into the sea of fire, from where no one will ever take them out.

Commentary: Reading this made me realize that many religions genuinely are different from each other. Christianity is genuinely different from Judaism, Islam is genuinely different from Christianity, Hinduism is genuinely different from all three. It's religious people who are the same everywhere; not the same as each other, obviously, but drawn from the same distribution. Is this true of atheistic humanists? Of transhumanists? Could you devise an experiment to test whether it was so, would you bet on the results of that experiment? Will they say the same of LessWrongers, someday? And if so, what's the point?

Now that I think on it, though, there might be a case for scientists being drawn from a different distribution, or computer programmers, or for that matter science fiction fans (are those all the same distributions as each other, I wonder?). It's not really hopeless.

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.

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?

H: I would spend hours aimlessly wandering the streets, kicking large stones and shouting, "I refute you thus!" It's embarrassing to recall.

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."

"The seeker after the truth is not one who studies the writings of the ancients and, following his natural disposition, puts his trust in them, but rather the one who suspects his faith in them and questions what he gathers from them, the one who submits to argument and demonstration, and not to the sayings of a human being whose nature is fraught with all kinds of imperfection and deficiency. Thus the duty of the man who investigates the writings of scientists, if learning the truth is his goal, is to make himself an enemy of all that he reads, and, applying his mind to the core and margins of its content, attack it from every side. He should also suspect himself as he performs his critical examination of it, so that he may avoid falling into either prejudice or leniency."

Instead, an individualist sub-culture must be built upon tolerance and honesty. I'd suggest three key norms:

Were it possible to trace the succession of ideas in the mind of Sir Isaac Newton, during the time that he made his greatest discoveries, I make no doubt but our amazement at the extent of his genius would a little subside. But if, when a man publishes his discoveries, he either through a design, or through habit, omit the intermediary steps by which he himself arrived at them, it is no wonder that his speculations confound them, and that the generality of mankind stand amazed at his reach of thought. If a man ascend to the top of a building by the help of a common ladder, but cut away most of the steps after he has done with them, leaving only every ninth of tenth step, the view of the ladder, in the condition which he has pleased to exhibit it, gives us a prodigious, but unjust view of the man who could have made use of it. But if he had intended that any body should follow him, he should have left the ladder as he constructed it, or perhaps as he found it, for it might have been a mere accident that threw it in his way... I think that the interests of science have suffered by the excessive admiration and wonder with which several first rate philosophers are considered, and that an opinion of the greater equality of mankind, in point of genius, and power of understanding, would be of real service in the present age." - Joseph Priestly, The History and present State of Electricity

The section where I've added an ellipsis is a section where he discusses Newton in more detail. That entire part of the text is worth reading. Priestly wrote the book before he did his work on the composition of air. The book is, as far as I am aware, the first attempt at actual history of science. (I'm meaning to read the whole thing at some point, but the occasionally archaic grammar makes for slow reading.)

All scientists despise the ideology of 'breakthroughs' --- I mean the belief that science proceeds from one revelation to another, each one opening up a new world of understanding and advancing still farther a sharp line of demarcation between what is true and what is false. Everyone actually engaged in scientific research knows that this way of looking at things is altogether misleading, and that the frontier between understanding and bewilderment is rather like the plasma membrane of a cell as it creeps over its substratum, a pushing forward here, a retraction there --- an exploratory probing that will eventually move forward the whole body of the cell... in real life, science does not prance from one mountain top to the next.

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.

I always thought I really hated getting email. It turns out that I was not a good reporter of my own actual behavior, which is something you’ll hear quite a bit if you follow psychological research. (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.”

Nassim Taleb, a popular author and critic of the financial industry, points out many such flaws but does not include the use of Monte Carlo simulations among them. He himself is a strong proponent of these simulations. Monte Carlo simulations are simply the way we do the math with uncertain quantities. Abandoning Monte Carlos because of the failures of the financial markets makes as much sense as giving up on addition and subtraction because of the failure of accounting at Enron or AIG’s overexposure in credit default swaps.

2 + 3 = 5, 3 + 2 = 5, 5 - 2 =3, and 5 - 3 = 2 are not four facts, but four different ways of looking at one fact. Furthermore, that fact is not a fact of arithmetic, to be taken on faith and memorized like nonsense syllables. It is a fact of nature, which children can discover for themselves, and rediscover or verify for themselves as many times as they need or want to.

The fact is this:

***** -- *** **

If you have before you a group of objects--coins or stones, for example---that looks like the group on the left, then you can make it into two groups that look like the ones on the right. Or--and this is what the two-way arrow means---if you have two groups that look like the ones on the right, you can make them into a group that looks like the one on the left.

This is not a fact of arithmetic, but a fact of nature. It did not become true only when human beings invented arithmetic. It has nothing to do with human beings. It is true all over the universe. One doesn't have to know any arithmetic to discover or verify it. An infant playing with blocks or a dog pawing at sticks might do that operation, though probably neither of them would notice that he had done it; for them, the difference between ***** and *** ** would be a difference that didn't make any difference. Arithmetic began (and begins) when human beings began to notice and think about this and other numerical facts of nature.

Discussion of how not to get lost in the woods

Arg, this post is bringing back memories of all kinds of backcountry stupidity (including a fair amount of my own stupidity), so I can't resist adding a comment about GPS devices. Any navigation tool -- GPS device, map, compass, sextant, whatever -- only works if you are using the navigation tool to relate yourself to the surrounding landscape. And you should never trust maps, GPS devices, compasses, or any tool if it contradicts what you're seeing in the surrounding landscape. I own a top-notch brand of GPS device, I got a top-quality map to go inside it, and when I checked the map against a landscape I knew well, I found error after error (which is true with all maps, by the way; one of the reasons I like paper maps is that I can make notations on it when I find errors).

"Oh? And what may that be?"

"It is not a supernatural creature."

"But it is all those other things?"

"Yes."

"Then I fail to see what difference it makes whether it be supernatural or not—so long as it is malefic, possesses great powers and life span and has the ability to change its shape at will."

"Ah, but it makes a great deal of difference, you see. It is the difference between the unknown and the unknowable, between science and fantasy—it is a matter of essence.

The necessity for marking our classes has brought with it a bias for false and excessive contrast, and we never invent a term but we are at once cramming it with implications beyond its legitimate content. There is no feat of irrelevance that people will not perform quite easily in this way; there is no class, however accidental, to which they will not at once ascribe deeply distinctive qualities. The seventh sons of seventh sons have remarkable powers of insight; people with a certain sort of ear commit crimes of violence; people with red hair have souls of fire; all democratic socialists are trustworthy persons; all people born in Ireland have vivid imaginations and all Englishmen are clods; all Hindoos are cowardly liars; all curly-haired people are good-natured; all hunch-backs are energetic and wicked, and all Frenchmen eat frogs. Such stupid generalisations have been believed with the utmost readiness, and acted upon by great numbers of sane, respectable people. And when the class is one's own class, when it expresses one of the aggregations to which one refers one's own activities, then the disposition to divide all qualities between this class and its converse, and to cram one's own class with every desirable distinction, becomes overwhelming.

Though [Ben Franklin] had been a vegetarian on principle, on one long sea crossing the men were grilling fish, and his mouth started watering:

I balanc'd some time between principle and inclination, till I recollectd that, when the fish were opened, I saw smaller fish taken out of their stomachs; then thought I, "if you eat one another, I don't see why we mayn't eat you." So I din'd upon cod very heartily, and continued to eat with other people, returning only now and then occasionally to a vegetable diet.

This is an old saying, which I learnt from the 1994 movie Forrest Gump (not otherwise a bastion of rationalism).

While we may judge people as irrational ("stupid") based on what they know (epistemic rationality, roughly), it's instrumental rationality that matters in the end.

“Tell me, Eben: how is’t, d’you think, that the planets are moved in their courses?”

“Why, said Ebenezer, “’tis that the cosmos is filled with little particles moving in vortices, each of which centers on a star; and ‘tis the subtle push and pull of these particles in our solar vortex that slides the planets along their orbs – is’t not?”

“So saith Descartes,” Burlingame smiled. “And d’you haply recall what is the nature of light?”

“If I have’t right,” replied Ebenezer, “’tis an aspect of the vortices – of the press of inward and outward forces in ‘em. The celestial fire is sent through space from the vortices by this pressure, which imparts a transitional motion to little light globules – ”

“Which Renatus kindly hatched for that occasion,” Burlingame interrupted. “And what’s more he allows his globules both a rectilinear and a rotatary motion. If only the first occurs when the globules smite our retinae, we see white light; if both, we see color. And if this were not magical enough – mirabile dictu! – when the rotatory motion surpasseth the rectilinear, we see blue; when the reverse, we see red; and when the twain are equal, we see yellow. What fantastical drivel!”

“You mean ‘tis not the truth? I must say, Henry, it sounds reasonable to me. In sooth, there is a seed of poetry in it; it hath an elegance.”

“Aye, it hath every virtue and but one small defect, which is, that the universe doth not operate in that wise.”

This would be free to use of course, and the site would not lock down the data (ie it would be exportable to various formats).

The nurse recorded the time of death, 9:21 P.M. He discovered, oddly, that the clock had halted at that moment —just the sort of mystical phenomenon that appealed to unscientific people. Then an explanation occurred to him. He knew the clock was fragile, because he had repaired it several times, and he decided that the nurse must have stopped it by picking it up to check the time in the dim light.

Who first called Reason sweet, I don't know. I suspect that he was a man with very few responsibilities, no children to rear, and no payroll to meet. An anchorite with heretical tendencies, maybe, or the idle youngest son of a wealthy Athenian. The dictates of Reason are often difficult to figure out, rarely to my liking, and profitable only by what seems a happy but remarkably unusual accident. Mostly, Reason brings bad news, and bad news of the worst sort, for, if it is truly the word of Reason, there is no denying it or weaseling out of its demands without simply deciding to be irrational. Thus it is that I have discovered, and many others, I notice, have also discovered, all sorts of clever ways to convince myself that Reason is "mere" Reason, powerful and right, of course, but infinitely outnumbered by reasons, my reasons.

Rejecting all organs of information therefore but my senses, I rid myself of the Pyrrhonisms with which an indulgence in speculations hyperphysical and antiphysical so uselessly occupy and disquiet the mind. A single sense may indeed be sometimes decieved, but rarely: and never all our senses together, with their faculty of reasoning. They evidence realities; and there are enough of these for all the purposes of life, without plunging into the fathomless abyss of dreams and phantasms. I am satisfied, and sufficiently occupied with the things which are, without tormenting or troubling myself about those which may indeed be, but of which I have no evidence.

I am sure that I really know many, many, things, and none more surely than that I love you with all my heart, and pray for the continuance of your life until you shall be tired of it yourself.

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. For millenia that was a huge and frightening question, and then we went and answered it, and now it's too trivial to point out. We found out where the sun goes at night.

Science isn't just a job, it's a means of determining truth. Methods of determining truth that aren't trustworthy in the laboratory don't become trustworthy when you leave it. There is no doctrine of applying scientific methodology to every aspect of one's life, you either follow trustworthy methods of investigation or you don't, and "follow trustworthy methods of investigation" is the core of science.

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.

Man cannot understand the perfection and imperfections of his chosen art if he cannot see the value in other arts. Following rules only permits development up to a point in technique and then the student and artist has to learn more and seek further. It makes sense to study other arts as well as those of strategy. Who has not learned something more about themselves by watching the activities of others? To learn the sword study the guitar. To learn the fist study commerce. To just study the sword will make you narrow-minded and will not permit you to grow outward.

Prompted by the discussion of Sam Harriss idea that science should provide for a universal moral code, I thought of this suitable reply given long ago:

[The] doctrine of right and wrong is perpetually disputed, both by the pen and the sword: whereas the doctrine of lines and figures is not so, because men care not in that subject what be truth, as a thing that crosses no man's ambition, profit, or lust. For I doubt not, but if it had been a thing contrary to any man's right of dominion, or to the interest of men that have dominion, that the three angles of a triangle should be equal to two angles of a square, that doctrine [would] have been, if not disputed, yet by the burning of all books of geometry suppressed, as far as he whom it concerned was able.

Into the darkness they go, the wise and the lovely. Crowned

With lilies and with laurel they go; but I am not resigned.

Lovers and thinkers, into the earth with you.

Be one with the dull, the indiscriminate dust.

A fragment of what you felt, of what you knew,

A formula, a phrase remains, --- but the best is lost.

The answers quick keen, the honest look, the laughter, the love,

They are gone. They have gone to feed the roses. Elegant and curled

Is the blossom. Fragrant is the blossom. I know. But I do not approve.

More precious was the light in your eyes than all the roses in the world.

Down, down, down into the darkness of the grave

Gently they go, the beautiful, the tender, the kind;

Quietly they go, the intelligent, the witty, the brave.

I know. But I do not approve. And I am not resigned.

Take the bettors in the racetrack experiment. Thirty seconds before putting down their money, they had been tentative and uncertain; thirty seconds after the deed, they were significantly more optimistic ans self-assured. The act of making a final decision--in this case, of buying a ticket--had been the critical factor. Once a stand had been taken, the need for consistency pressured these people to bring what they felt and believed into line with what they had already done. They simply convinced themselves that they had made the right choice and, no doubt, felt better and it all.

The majority of people in this world are ataxic: they cannot coordinate their mental muscles to make a purposed movement. They have no real Will, only a set of wishes, many of which contradict others. The victim wobbles from one to the other (and it is no less wobbling because the movements may occasionally be very violent), and at the end of life the movements cancel each other out. Nothing has been achieved, except the one thing of which the victim is not conscious: the destruction of his own character, the confirming of indecision.

Crowley's writings are an odd mixture of utter raving, self-conscious mysticism, and surprising introspective clarity.

Suppose we know someone's objective and also know that half the time that person correctly figures out how to achieve it and half the time he acts at random. Since there is generally only one right way of doing things (or perhaps a few) but very many wrong ways, the "rational" behavior can be predicted but the "irrational" behavior cannot. If we predict the person's behavior on the assumption that he is rational, we will be right half the time. If we assume he is irrational, we will almost never be right, since we still have to guess which irrational thing he will do. We are better off assuming he is rational and recognizing that we will sometimes be wrong. To put the argument more generally, the tendency to be rational is the consistent (and hence predictable) element in human behavior. The only alternative to assuming rationality (other than giving up and assuming that human behavior cannot be understood and predicted) would be a theory of irrational behavior - a theory that told us not only that someone would not always do the rational thing but also which particular irrational thing he would do. So far as I know, no satisfactory theory of that sort exists.

Imagine that everyone in North America took [a cognitive enhancement pill] before retiring and then woke up the next morning with more memory capacity and processing speed... I believe that there is little likelihood that much would change the next day in terms of human happiness. It is very unlikely that people would be better able to fulfill their wishes and desires the day after taking the pill. In fact, it is quite likely that people would simply go about their usual business - only more efficiently. If given more memory capacity and processing speed, people would, I believe: carry on using the same ineffective medical treatments because of failure to think of alternative causes; keep making the same poor financial decisions because of overconfidence; keep misjudging environmental risks because of vividness; play host to the [tempting bad ideas] of Ponzi and pyramid schemes; [and] be wrongly influenced in their jury decisions by incorrect testimony about probabilities... The only difference would be that they would be able to do all of these things much more quickly!

Whether their motives were righteous or venal, highminded or base, noble or ig-, in retrospect the obvious verdict is that they were all morons--yes, even the distinguished fellows and visiting scholars at think tanks and deans of international studies schools. They were morons because the whole moral, political and practical purpose of their scheme depended on its going exactly according to plan. Which nothing ever does. The Latin phrase for this logical fallacy would be Duh. Some of them were halfway intelligent; some of them may even have been well-intentioned; but they lacked imagination, and this is a fatal flaw. What we learn from history is that it never turns out like it's supposed to. And the one thing we know for sure about the future is that it won't be like we think.

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.

His mind refused to accept a simple inference from simple facts, which were patent to all the world. The very simplicity of the conclusion was of itself enough to make him reject it, for he had an elective affinity for everything that was intricate. He was a prey to intellectual over-subtlety.

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.

If a man objects to truths that are all too evident, it is no easy task finding arguments that will change his mind. This is proof neither of his own strength nor of his teacher's weakness. When someone caught in an argument hardens to stone, there is just no more reasoning with them.

"Well, how about this — that man, unlike animals, is a creature who experiences an insurmountable need for knowledge? I've read that somewhere."

"So have I," said Valentine. "But the trouble is that man, or in any case the common man, easily overcomes this need for knowledge of his. It seems to me that he doesn't have such a need at all. There's a need to understand, but knowledge is not required for that. 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. A few memorized formulas plus some so-called intuition, so-called practical acumen, and so-called common sense."

It's a wonderful thing to be clever, and you should never think otherwise, and you should never stop being that way. But what you learn, as you get older, is that there are a few million other people in the world all trying to be clever at the same time, and whatever you do with your life will certainly be lost - swallowed up in the ocean - unless you are doing it with like-minded people who will remember your contributions and carry them forward. That is why the world is divided into tribes.

Intuitively, I wonder about the honesty and proficiency of writers who opine on everything from Iran to education to drug policy to health care to cap and trade to race. Perhaps these people simply have more brains than me, but the catch-all nature of punditry, the need to speak on every policy topic as though one were an expert, is exactly what I hope to avoid.

When I became convinced that the Universe is natural — that all the ghosts and gods are myths, there entered into my brain, into my soul, into every drop of my blood, the sense, the feeling, the joy of freedom. The walls of my prison crumbled and fell, the dungeon was flooded with light, and all the bolts, and bars, and manacles became dust. I was no longer a servant, a serf, or a slave. There was for me no master in all the wide world — not even in infinite space. I was free — free to think, to express my thoughts — free to live to my own ideal — free to live for myself and those I loved — free to use all my faculties, all my senses — free to spread imagination’s wings — free to investigate, to guess and dream and hope — free to judge and determine for myself — free to reject all ignorant and cruel creeds, all the “inspired” books that savages have produced, and all the barbarous legends of the past — free from the popes and priests — free from all the “called” and “set apart” — free from sanctified mistakes and holy lies — free from the fear of eternal pain — free from the winged monsters of the night — free from devils, ghosts, and gods. For the first time I was free. There were no prohibited places in all the realms of thought — no air, no space, where fancy could not spread her painted wings — no chains for my limbs — no lashes for my back — no fires for my flesh — no master’s frown or threat — no following another’s steps — no need to bow, or cringe, or crawl, or utter lying words. I was free. I stood erect and fearlessly, joyously, faced all worlds.

And then my heart was filled with gratitude, with thankfulness, and went out in love to all the heroes, the thinkers who gave for the liberty of hand and brain — for the freedom of labor and thought — to those who fell in the fierce fields of war, to those who died in dungeons bound with chains — to those who proudly mounted scaffold’s stairs — to those whose bones were crushed, whose flesh was scarred and torn — to those by fire consumed — to all the wise, the good, the brave of every land, whose thoughts and deeds have given freedom to the sons of men. And then I vowed to grasp the torch that they had held, and hold it high, that light might conquer darkness still.

After all, it would be absurd to criticize witchcraft as unscientific, as this would ignore the primordial division between mythos and logos. Let me see if I have this straight: Belief in demons, the evil eye, and the medicinal value of a cannibal feast are perversions of the real witchcraft - -which is drenched with meaning, intrinsically wholesome, integral to our humanity, and here to stay.

Despite the fact that you arrived in this world with nothing but an unborn Buddha-mind, your partiality for yourselves now makes you want to have things move in your own way. You lose your temper, become contentious, and then you think, "I haven't lost my temper. That fellow won't listen to me. By being so unreasonable he has made me lose it." And so you fix belligerently on his words and end up transforming the valuable Buddha-mind into a fighting spirit. By stewing over this unimportant matter, making the thoughts churn over and over in your mind, you may finally get your way, but then you fail in your ignorance to realize that it was meaningless for you to concern yourself over such a matter.

Witching was turning out to be mostly hard work and really short on magic of the zap!-glingle-glingle-glingle variety. There was no school and nothing that was exactly like a lesson. But it wasn’t wise to try to learn witching all by yourself, especially if you had a natural talent. If you got it wrong, you could go from ignorant to cackling in a week ...

When you got right down to it, it was all about cackling. No one ever talked about this, though. Witches said things like “You can never be too old, too skinny, or too warty,” but they never mentioned the cackling. Not properly. They watched out for it, though, all the time.

It was all too easy to become a cackler. Most witches lived by themselves (cat optional) and might go for weeks without ever seeing another witch. In those times when people hated witches, they were often accused of talking to their cats. Of course they talked to their cats. After three weeks without an intelligent conversation that wasn’t about cows, you’d talk to the wall. And that was an early sign of cackling.

“Cackling,” to a witch, didn’t just mean nasty laughter. It meant your mind drifting away from its anchor. It meant you losing your grip. It meant loneliness and hard work and responsibility and other people’s problems driving you crazy a little bit at a time, each bit so small that you’d hardly notice it, until you thought that it was normal to stop washing and wear a kettle on your head. It meant you thinking that the fact you knew more than anyone else in your village made you better than them. It meant thinking that right and wrong were negotiable. And, in the end, it meant you “going to the dark,” as the witches said. That was a bad road. At the end of that road were poisoned spinning wheels and gingerbread cottages.

What stopped this was the habit of visiting. Witches visited other witches all the time, sometimes traveling quite a long way for a cup of tea and a bun. Partly this was for gossip, of course, because witches love gossip, especially if it’s more exciting than truthful. But mostly it was to keep an eye on one another.

Today Tiffany was visiting Granny Weatherwax, who was in the opinion of most witches (including Granny herself) the most powerful witch in the mountains. It was all very polite. No one said, “Not gone bats, then?” or “Certainly not! I’m as sharp as a spoon!” They didn’t need to. They understood what it was all about, so they talked of other things. But when she was in a mood, Granny Weatherwax could be hard work.
