In 1736 I lost one of my Sons, a fine Boy of 4 Years old, by the Smallpox taken in the common way. I long regretted bitterly and still regret that I had not given it to him by Inoculation. This I mention for the Sake of Parents who omit that Operation on the Supposition that they should never forgive themselves if a Child died under it; my Example showing that the Regret may be the same either way, and that therefore the safer should be chosen.

(To provide some context: at the time, the smallpox vaccine used a live virus, and carried a non-trivial risk of death for the recipient. However, it was still safer on the whole than not being immunized.)

Whatever elaborate, and grotesquely counter-intuitive, underpinnings there might be to familiar reality, it stubbornly continues to be familiar. When Rutherford showed that atoms were mostly empty space, did the ground become any less solid? The truth itself changes nothing.

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. Everest, or the universe. Questions can be simply inappropriate, however heartfelt their framing.

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.

If you show me
That, say, homeopathy works,
Then I will change my mind
I’ll spin on a fucking dime
I’ll be embarrassed as hell,
But I will run through the streets yelling
It’s a miracle! Take physics and bin it!
Water has memory!
And while its memory of a long lost drop of onion juice is Infinite
It somehow forgets all the poo it’s had in it!

You show me that it works and how it works
And when I’ve recovered from the shock
I will take a compass and carve Fancy That on the side of my cock.

Let us be certain of a fact before being concerned with its cause. It is true that this method is too lengthy for most people who naturally run to the cause and overlook the certitude about facts; but at last we will avoid the ridicule of finding the cause of what does not exist.

I definitely think there is great art out there that was solely designed to give people what they want; in film, someone like Chaplin comes to mind. I mean, giving people what they want is an art unto itself, but I think the real challenge in that method is finding a way to give them what they want while giving them more.

Dirge without Music
Edna St. Vincent Millay

I am not resigned to the shutting away of loving hearts in the hard ground.
So it is, and so it will be, for so it has been, time out of mind:
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.

There should be a word for the things we do not because we want to but because we want to be the kind of person who wants to.

You can make a small program (say, 1,000 lines) work through brute force even when breaking every rule of good style. For a larger program, this is simply not so. If the structure of a 100,000-line program is bad, you will find that new errors are introduced as fast as old ones are removed.

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.

This is how Vetinari thinks, his soul exulted. Plans can break down. You cannot plan the future. Only presumptuous fools plan. The wise man steers.

—Terry Pratchett, Making Money

Although thought by a madman in the book, there seems to be truth in this quote. People often seem to think of the future as a coherent, specific story not unlike the one woven by the brain from the past events. Unpleasant surprises happen when the real events inevitably deviate from those imagined.

"...natural selection built the brain to survive in the world and only incidentally to understand it at a depth greater than is needed to survive. The proper task of scientists is to diagnose and correct the misalignment." -- E. O. Wilson

Where all men think alike, no one thinks very much.

-Walter Lippmann

"The usual touchstone of whether what someone asserts is mere persuasion or at least a subjective conviction, i.e., firm belief, is betting. Often someone pronounces his propositions with such confident and inflexible defiance that he seems to have entirely laid aside all concern for error. A bet disconcerts him. Sometimes he reveals that he is persuaded enough for one ducat but not for ten. For he would happily bet one, but at ten he suddenly becomes aware of what he had not previously noticed, namely that it is quite possible that he has erred."

Do not bear this single habit of mind, to think that what you say and nothing else is true. ...For a man, though he be wise, it is no shame to learn – learn many things, and not maintain his views too rigidly.

Now, most people believe in reason the way they believe in cold showers; it's O.K. if you don't overdo it. Very few people are so insensitive as to go around applying logic to other people's beliefs...

...Fenwick has no understanding of such things. I think I should tell you that Fenwick enjoys reasoning. He uses his mind the way a sprinter uses his shoes: to get from one point to another with a maximum of speed and a minimum of nonsense.

The very presence of surprising false results that take some time to get refuted might give scientists the illusion that they are getting somewhere - since the field changes all the time - and bravely applying the scientific method - since we are bold enough to repudiate the fashionable hypotheses of ten years ago.

The effort to understand how an airplane flies is sometimes called "Theory of Flight." Under that name, it has a bad reputation with pilots. Most pilots think that theory is useless, that practice is what does it. Yet you can't help having a theory: whatever you do, from peeling potatoes to flying airplanes, you go on the basis of some mental image of what's what — and that's all "theory" amounts to. And if your ideas of what's what are correct, you will do it well.

"If I were not here, what would you do?" asked Holo.

"First I'd work out whether it was true or not, then I'd pretend to believe his story."

"And why is that?"

"If it's true, I can turn a profit just by going along with it. If it's a lie, then someone somewhere is up to something -- but I can still come out ahead if I keep my eyes and ears open."

"Mm. And given that I am here, and I've told you he's lying, then..."

Lawrence finally realized what had been eluding him. "Ah."

"Heh. See, there was nothing over which to agonize so. Either way you'll be pretending to accept his proposal," said Holo, grinning. Lawrence had no retort.

"The Fundamental Attribution Error is the reason why we love TV shows like The Dog Whisperer or Supernanny, in which seem­ingly irredeemable dogs and kids are tamed by outsiders who come in with a new system of discipline. At the beginning of the episodes, we're presented with a dog that bites everything in sight, or a child who won't obey the simplest of commands, and we sim­ply can't avoid jumping to conclusions about their character: That dog is vicious. That boy is a terror. And when they're reformed, in the course of a short intervention, it blows our minds.

If we could cure ourselves of the Fundamental Attribution Error, these shows would seem obvious to the point of absurdity. (It would be like watching a show whose premise was that if you take scalding-hot liquids-dangerous and slippery-and stick them in the freezer for a long time, they renounce their fiery former selves and turn to ice!)"

Errare humanum est, sed perseverare diabolicum.

Rough translation: To err is human, but to persist in error diabolical.

(Saw the quote in William Langewiesche's Fly By Wire; it is often attributed to Seneca on the Webs, but I can find no citation.)

I can't remember the source of the quote I'm thinking of, but it goes something like this:

"People always remark that I know so much about science and so little about celebrities, but they fail to see that the two are related."

Does anyone know the original quote?

"Fanatics may suppose, that dominion is founded on grace, and that saints alone inherit the earth; but the civil magistrate very justly puts these sublime theorists on the same footing with common robbers, and teaches them by the severest discipline, that a rule, which, in speculation, may seem the most advantageous to society, may yet be found, in practice, totally pernicious and destructive." -- David Hume

More of an anti-fanaticism quotation, but it seems to belong.

A large part of education is learning to use your own judgement.

-- Ardath Mayhar, Khi to Freedom

[T]he modern student has no appreciation of the modes of thinking, the prejudices, and other difficulties agains which the theory of probability had to struggle when it was new. Nowadays newspapers report on samples of public opinion, and the magic of statistics embraces all phases of life to the extent that young girls watch the statistics of their chances to get married. Thus everyone has acquired a feeling for the meaning of statements such as "the chances are three in five". Vague as it is, this intuition serves as background and guide for the first step.

This is more depressing than inspiring, but the final sentence is worth contemplating. It's from a review of a short book by the 19th-century economist Francis Edgeworth, showing how to begin a mathematical (utilitarian) treatment of morality.

His style, if not obscure, is implicit, so that the reader is left to puzzle out every important sentence like an enigma. It is probable that most of the propositions are worth puzzling out, and that they would be puzzled out if some great pecuniary matter like a great lawsuit or the design for a great engineering work depended upon their comprehension.

We can add new methods to our lives regardless of age, circumstances, situation, or anything else. It simply requires a willingness to learn. A learning methods that can radically improve our lives doesn't necessarily take a lot of time.

Imagine the difference between a newborn infant and a two-year old. An infant cannot walk, talk, coordinate its body, control its bowels, eat solid food, understand language, or see very well. By two, the child is well on its way to mastering all these. That's how much learning a human can do in two years.

That same transformational amount of learning can take place in any similar period of time. In fact, as an adult, we can learn even faster. All it takes is commitment and willingness.

As logic stands you couldn't meet a man
Who's from the future
But logic broke, as he appeared he spoke
About the future:

Part of the future
All we have is now
All we've ever had was now

If you persuade yourself that you can do a certain thing, provided this thing is possible, you will do it, however difficult it may be. If, on the contrary, you imagine that you cannot do the simplest thing in the world, it is impossible for you to do it, and molehills become for you unscalable.
