"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."

--Patrick McKenzie, "Some Perspective on the Japan Earthquake"

"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...

"Nothing exists in contradiction to nature, only in contradiction to what we know of it." - Dana Scully, The X-Files

Madolyn: "Why is the last patient of the day always the hardest?"

Costigan: "Because you're tired and you don't give a shit. It's not supernatural."

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

Everybody has a plan until they get punched in the mouth.

--Mike Tyson

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.

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."

We'll eliminate the fucking stupid guesses pretty quickly - it doesn't take long to show that we can't move things with our minds. Eventually, you start to build a pretty cool system of things so you can make better and better guesses. and you can totally use data to make good guesses; you don't always have to invent something completely new every time. I'm just saying that's all the data does, helps make good guesses. It doesn't prove shit.

And look! That method is deductive! What incredibly good news! You don't have to derive a universal statement from a bunch of single events, which is great because you can't; instead, you just guess a universal statement and then see if you can't find an event that breaks it. You can't get from "the sun keeps rising" to "the sun will always rise" but if one day the sun doesn't come up, you can be damn sure about "the sun does not always rise." All you need is one bad apple and you know for sure that not every apple is good, no induction needed. QED, motherfuckers.

And - AND - now we know what is and isn't science! Holy fuck I am on fire here. Not actually. Just- look, I'm solving lots of things, is my point. Scientific theories are falsifiable - they're incompatible with certain things we could observe. They predict shit, and then we see if that shit really happens. Back when we thought Newton's Laws were totally, completely true, Mercury had this weird fuck wobble in its orbit that said we should find another planet. Except we looked and no planet. And now we know for sure that Newton wasn't completely right. Einstein? He was a patent clerk for fuckssake, and he came up with a fucking incredible guess. And we just keep devising more and more complicated tests to check it out, and it keeps on passing. When it does finally fail, we'll fucking know. There won't be aaaaany confusion whatsoever. Souls? How the fuck would we go about testing for souls? "Well, we cut him open, and we didn't find a soul, so..." "Yeah, but you can't see souls! That's the whole point!" So you're saying we can't ever test for souls? That's fine, just, it means souls can't come to the science party. They're not falsifiable. You must be THIS FALSIFIABLE to ride the science ride, and souls just aren't.

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?

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.

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

--Thomas Sowell

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.

Colonel John Boyd

On the other hand:

The Stoical scheme of supplying our wants by lopping off our desires, is like cutting off our feet when we want shoes.

Jonathan Swift

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

What a stupid fucking question. I could have answered it in a second, if Sarasti hadn't forced me to understand it first.

Peter Watts, Blindsight

學而不思則罔,思而不學則殆。 To study and not think is a waste. To think and not study is dangerous.

-- Confucius

Science offers the boldest metaphysics of the age. It is a thoroughly human construct, driven by the faith that if we dream, press to discover, explain, and dream again, thereby plunging repeatedly into new terrain, the world will somehow come clearer and we will grasp the true strangeness of the universe. And the strangeness will all probe to be connected, and make sense.

E.O. Wilson

"Washington had always taught himself from experience. He learned the lessons of the American war all the more readily because he had no conventional lessons to unlearn. … Long before the end of the war, Washington had become much more effective than any of his military opponents. But this did not mean that what he had taught himself would have made him a great general on the battlefields of Europe. Evolved not from theory but from dealing with specific problems, his preeminence was achieved through a Darwinian adaptation to environment. It was the triumph of a man who knows how to learn, not in the narrow sense of studying other people's conceptions, but in the transcendent sense of making a synthesis from the totality of experience." -- James Thomas Flexner in Washington : The Indispensable Man (1984), Chapter 23 : Goodbye to War, p. 183
