"The story of Japanese railways during the earthquake and tsunami is the story of an unceasing drumbeat of everything going right [...] The overwhelming response of Japanese engineering to the challenge posed by an earthquake larger than any in the last century was to function exactly as designed. Millions of people are alive right now because the system worked and the system worked and the system worked.

That this happened was, I say with no hint of exaggeration, one of the triumphs of human civilization. Every engineer in this country should be walking a little taller this week. We can’t say that too loudly, because it would be inappropriate with folks still missing and many families in mourning, but it doesn’t make it any less true."

"To convince someone of the truth, it is not enough to state it, but rather one must find the path from error to truth." Wittgenstein. "Remarks on Frazer's Golden Bough," p. 119

Shit, if I took time out to have an opinion about everything, I wouldn't get any work done...

-- L. Bob Rife, Snow Crash

-3VAuroch
While I enjoy a good Snow Crash quote as much as the next guy (Hell, probably more), this doesn't seem particularly relevant to rationality at all.

I disagree. Many people, in my experience, seem to think that everyone ought to have an opinion on every subject presented them, as if developing reasonable opinions were something that did not take significant amounts of information or effort.

I am happy to acknowledge that there is no end to the subjects that I have no right to an opinion on, because I haven't put in the time or effort to justify holding forth any position whatsoever.

2Lumifer
Such people typically do not require an opinion to be reasonable :-D

In my government class in high school, we had to do an exercise that involved saying which side we were on for several standard political issues.

I remember thinking: "Fuck, I don't have an opinion on gun control!" But there was no scale 1-5 strongly agree to strongly disagree. It was just, "which side are you on?" I even complained to the teacher and she said "Just pick one. You have to have some opinion." Then we had to argue for our positions with the other students at our table.

Basically, "come up with an opinion. Any opinion is fine, just make sure it suits your personality. Then act like you believe it strongly enough to argue for it. Huzzah commitment bias. Make it part of your identity by comparing yourself to your neighbors. No time/internet access will be given during this assignment to do any research."

I ended up arguing for gun control, my (explicit) reasoning internally was "this is the liberal position. When I think about liberals, I think of my parents who are relatively reasonable, when I think of conservatives I think of [the conservatives my parents point out and make fun of] who are crazy. So more likely, the liberals are right."

This is like an exercise in anti-rationality, but I bet most people would think it is a good thing.
3polymathwannabe
Politics appears to be all about choosing a fixed position and coming up with whatever aguments may support them, which is the exact inverse of what rational debate should be.
7Mestroyer
I would be even less charitable. Politics is mainly about memorizing arguments for your position someone else came up with, presenting them well, and making them sound like responses to your opponents' memorized arguments, and strategically emphasizing the more moderate aspects of your position (if not plainly lying about the less moderate aspects) to appeal to the median voter.

When I studied business management, I always felt revulsion toward my marketing courses. Now my cousin has just finished a post-graduate degree in "political marketing," which drives my revulsion to critical mass.

I agree, but the first VNM axiom doesn't: totality of the preference ordering. Neither does Eliezer.
6Oscar_Cunningham
VNM agents are still allowed to be indifferent. I like Robin Hanson's post about this. Or there's this quote in from Russell and Norvig:
[-]gwern100

The quote actually was about betting. From Artificial Intelligence: A Modern Approach, by Russell & Norvig, on Dutch books:

One might think that this betting game is rather contrived. For example, what if one refuses to bet? Does that end the argument? The answer is that the betting game is an abstract model for decision-making situation in which every agent is unavoidably involved at every moment. Every action (including inaction) is a kind of bet, and every outcome can be seen as a payoff of the bet. Refusing to bet is like refusing to allow time to pass.

2Oscar_Cunningham
Thanks for the correction! EDIT: My copy has "One can no more refuse to bet than one can refuse to allow time to pass." Different editions, I guess.
2Richard_Kennaway
They still have to know they're indifferent.

Why isn't saying "I don't know" a reasonable approach to the issue when ones knowledge is vague enough to be useless for knowledge (and can only be made useful if the case was a bizarre thought experiment), Just because one couldtheoretically bet on something doesn't mean one is in a position to bet. (For example to say that I don't know how to cure a disease so I will go to the doctor, or I don't know what that person's name is (even though I know it isn't "Xpchtl Vaaaaaarax") so I should ask someone, Or I don't know how life began. Or I don't know how many apples are on the tree outside (even though I know it isn't 100 million))

The kind of people Desrtopa is talking about wouldn't be contented with answers such as “10 to 1000”.
3AshwinV
It sort of does.. I haven't read snow crash, but the quote prima facie seems to support the virtue of narrowness
0VAuroch
Not unless you interpret 'narrowness' in a very odd way.
2AshwinV
Uhm.. yeah. I guess. Just saying that no one guy can do everything or know everything, therefore its not possible to develop knowledge in all fields like that.. dont know what context was used in Snow Crash though..
0VAuroch
That interpretation doesn't make sense to me in or out of context. It's dismissive of thinking about things.
2AshwinV
That wasn't my intention :D Just that you have to know when to admit you don't know enough about something.

A serious prophet upon predicting a flood should be the first man to climb a tree.

--Stephen Crane, The Red Badge of Courage.

Charlatans also tend to do this. Often, a charlatan would dedicate her life to selling boats. When questioned if she really believes in the floods, obviously she does! Why else would she be wasting her life as a boatwright?
1DanielLC
Given that the most well known story of a prophet predicting a flood involved him building a boat, that doesn't sound like anything particularly insightful. What's the context?

I think it means that Prophets aren't worth taking seriously unless they are staking their own reputation, well-being, or money on what they predict. There are many people who claim to know a particular thing for certain but who curiously aren't putting all of their own money on it. A perfect example probably being people selling stocks and investment plans.

I’m better at tests than reality. Reality doesn’t tell you which of a million bits of information to look at.

I had to see the context to parse that. He's saying that he's better at tests than he is at reality. Not that he's better at tests than reality is.

Heaven and Earth are heartless
treating creatures like straw dogs.

- Tao Te Ching

Su Ch'e commentary on this verse explains: "Heaven and Earth are not partial. They do not kill living things out of cruelty or give them birth out of kindness. We do the same when we make straw dogs to use in sacrifices. We dress them up and put them on the altar, but not because we love them. And when the ceremony is over, we throw them into the street, but not because we hate them."

- Straw dog in Wikipedia

For Popper (if not for some of his later admirers), falsifiability was not a crude bludgeon. Rather, it was the centerpiece of a richly-articulated worldview holding that millennia of human philosophical reflection had gotten it backwards: the question isn’t how to arrive at the Truth, but rather how to eliminate error. Which sounds kind of obvious, until I meet yet another person who rails to me about how empirical positivism can’t provide its own ultimate justification, and should therefore be replaced by the person’s favorite brand of cringe-inducing ugh.

--Scott Aaaronson, Retiring falsifiability? A storm in Russell’s teacup

Philosophy Bro writing as Popper:

So how does science proceed, if induction is fucked (which it is) and we can't logically determine how to have new ideas (which we can't)? Easy - just take a fucking guess. No, I don't mea- dammit, you asshole, I don't mean "guess how science works", I mean guessing just is how science works. Just start guessing shit and go from there. Of course you're going to make a couple stupid guesses at first. Seriously, some of the shit you're going to try is going to be genuinely fucked in the head. Remember when we thought heavier objects would fall faster? Boy was that wrong. But we took a guess, tried it out, and it didn't work. Instead of being whiny babies about it, scientists just took another guess and then tested that out, too. That's the process: guess, and then you test that guess. And if the test works, you're like "Huh! That was an even better guess than I thought." And the more tests it survives, the more people are like, "Great guess! I'll bet that's probably it." And then you get to a test that your guess doesn't pass, and you're like, "Welp, close but no cigar. Back to the drawing board."

Also, this from his summary of Nietzsche's "Thus Spoke Zarathustra":

Humanity isn't an end, it's a fork in the road, and you have two options: "Animal" and "Superman". For some reason, people keep going left, the easy way, the way back to where we came from. Fuck 'em. Other people just stand there, staring at the signposts, as if they're going to come alive and tell them what to do or something. Dude, the sign says fucking "SUPERMAN". How much more of a clue do these assholes want?

Better beware of notions like genius and inspiration; they are a sort of magic wand and should be used sparingly by anybody who wants to see things clearly.

-- José Ortega y Gasset

You must not fight too often with one enemy, or you will teach him all your art of war.

  • Napoleon Bonaparte
0wedrifid
(Wholeheartedly endorse this quote.) It seems that there must be some corollary here. That guy who is being taught of the art of war seems to be benefiting from fighting often with one enemy. If you are either better at learning from experience or have more need to learn arts of war (ie. you are the newbie not the master) then fighting often with one enemy seems to help you (all non-epistemic issues such as "all your soldiers die" being equal).
1Jiro
Fighting someone a lot teaches him your art of war, but may not teach him the art of war in general. He may be better off fighting multiple people, learning less about each one.
0wedrifid
Yes. Nevertheless, to whatever extent it is bad for Napoleon to fight one enemy often and thereby teach him it is beneficial to the person learning. If the benefit given to the enemy is enough that even Napoleon (the learner's enemy) cares about it then presumably it is a consideration for the person doing the learning as well. Presumably each side cares about the learning that has been done specifically because they care about the outcome of conflicts between the two of them. One is helped, the other hindered. Things that influence the outcome of direct battle between two sides tend to be like that. Yes, or he may better off learning about some economic matters (thereby supplementing his 'art' with superior firepower). Or he may be better off buying delicious cookies. I didn't oppose the notion of opportunity cost. In fact, for the sake of pedantry I even included a 'ceritus paribus' clause.

But, while nothing can be done about the past, much can be done in the present to prepare for the future.

--Thomas Sowell

Now life is the only art that we are required to practice without preparation, and without being allowed the preliminary trials, the failures and botches, that are essential for the training of a mere beginner. In life, we must begin to give a public performance before we have acquired even a novice's skill; and often our moments of seeming mastery are upset by new demands, for which we have acquired no preparatory facility. Life is a score that we play at sight, not merely before we have divined the intentions of the composer, but even before we have mastered our instruments; even worse, a large part of the score has been only roughly indicated, and we must improvise the music for our particular instrument, over long passages. On these terms, the whole operation seems one of endless difficulty and frustration; and indeed, were it not for the fact that some of the passages have been played so often by our predecessors that, when we come to them, we seem to recall some of the score and can anticipate the natural sequence of the notes, we might often give up in sheer despair. The wonder is not that so much cacophony appears in our actual individual lives, but that there is any appearance of harmony and progression.

-- Lewis Mumford, The Conduct of Life

I'm a big fan of the cognitive utility of the old phrase: "The exception that proves the rule." But then I'm kind of an exception in that regard, since anytime I mention I like that, I get deluged with logical and etymological objections.

I merely mean that an exception that is famous for being exceptional suggests a general tendency in the opposite direction. The canonical example is that Beethoven's titanic fame as a deaf composer suggests that most composers aren't deaf, while, say, the lack of obsessive publicity about painter David Hockney's late onset deafness suggests that deafness isn't all that big of a deal, one way or another, to painters. Judging from the immortal fame of Beethoven's battle with deafness, we can assume that there aren't many deaf composers, while the ho-hum response to Hockney's deafness suggests that we can't make strong quantitative assumptions about painters and deafness.

Steve Sailor

I would like to add something that's not essential to the science, but something I kind of believe, which is that you should not fool the layman when you're talking as a scientist. I am not trying to tell you what to do about cheating on your wife, or fooling your girlfriend, or something like that, when you're not trying to be a scientist, but just trying to be an ordinary human being. We'll leave those problems up to you and your rabbi. I'm talking about a specific, extra type of integrity that is not lying, but bending over backwards to show how you're maybe wrong, that you ought to have when acting as a scientist. And this is our responsibility as scientists, certainly to other scientists, and I think to laymen.

Richard Feynman in Cargo Cult Science

The most important thing in life is to be free to do things. There are only two ways to insure that freedom - you can be rich or you can you reduce your needs to zero.
