Quotes from Rationality: From AI to Zombies

“Since the beginning
not one unusual thing
has ever happened.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Oops is the sound we make when we improve our beliefs and strategies; so to look back at a time and not see anything you did wrong means that you haven’t learned anything or changed your mind since then.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Many philosophers—particularly amateur philosophers, and ancient philosophers—share a dangerous instinct: If you give them a question, they try to answer it.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“What is true is already so. Owning up to it doesn’t make it worse. Not being open about it doesn’t make it go away. And because it’s true, it is what is there to be interacted with. Anything untrue isn’t there to be lived. People can stand what is true, for they are already enduring it. —Eugene Gendlin”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Logic stays true, wherever you may go,
So logic never tells you where you live.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“When you find yourself in philosophical difficulties, the first line of defense is not to define your problematic terms, but to see whether you can think without using those terms at all. Or any of their short synonyms. And be careful not to let yourself invent a new word to use instead. Describe outward observables and interior mechanisms; don’t use a single handle, whatever that handle may be.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“The actual consumers of knowledge are the children—who can’t pay, can’t vote, can’t sit on the committees. Their parents care for them, but don’t sit in the classes themselves; they can only hold politicians responsible according to surface images of “tough on education.” Politicians are too busy being re-elected to study all the data themselves; they have to rely on surface images of bureaucrats being busy and commissioning studies—it may not work to help any children, but it works to let politicians appear caring. Bureaucrats don’t expect to use textbooks themselves, so they don’t care if the textbooks are hideous to read, so long as the process by which they are purchased looks good on the surface. The textbook publishers have no motive to produce bad textbooks, but they know that the textbook purchasing committee will be comparing textbooks based on how many different subjects they cover, and that the fourth-grade purchasing committee isn’t coordinated with the third-grade purchasing committee, so they cram as many subjects into one textbook as possible. Teachers won’t get through a fourth of the textbook before the end of the year, and then the next year’s teacher will start over. Teachers might complain, but they aren’t the decision-makers, and ultimately, it’s not their future on the line, which puts sharp bounds on how much effort they’ll spend on unpaid altruism . . .”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“So the next time you doubt the strangeness of the future, remember how you were born in a hunter-gatherer tribe ten thousand years ago, when no one knew of Science at all. Remember how you were shocked, to the depths of your being, when Science explained the great and terrible sacred mysteries that you once revered so highly. Remember how you once believed that you could fly by eating the right mushrooms, and then you accepted with disappointment that you would never fly, and then you flew. Remember how you had always thought that slavery was right and proper, and then you changed your mind. Don't imagine how you could have predicted the change, for that is amnesia. Remember that, in fact, you did not guess. Remember how, century after century, the world changed in ways you did not guess.

Maybe then you will be less shocked by what happens next.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If you once tell a lie, the truth is ever after your enemy.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Listen to hypotheses as they plead their cases before you, but remember that you are not a hypothesis, you are the judge. Therefore do not seek to argue for one side or another, for if you knew your destination, you would already be there.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“A random key does not open a random lock just because they are “both random.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If you see your activities and situation originally, you will be able to originally see your goals as well. If you can look with fresh eyes, as though for the first time, you will see yourself doing things that you would never dream of doing if they were not habits.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“What does it mean to call for a “democratic” solution if you don’t have a conflict-resolution mechanism in mind?
I think it means that you have said the word “democracy,” so the audience is supposed to cheer. It’s not so much a propositional statement, as the equivalent of the “Applause” light that tells a studio audience when to clap.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“John Kenneth Galbraith said: “Faced with the choice of changing one’s mind and proving that there is no need to do so, almost everyone gets busy on the proof.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If the box contains a diamond, I desire to believe that the box contains a diamond; If the box does not contain a diamond, I desire to believe that the box does not contain a diamond; Let me not become attached to beliefs I may not want.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“The police officer who puts their life on the line with no superpowers, no X-Ray vision, no super-strength, no ability to fly, and above all no invulnerability to bullets, reveals far greater virtue than Superman—who is a mere superhero.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“But in probability theory, absence of evidence is always evidence of absence. If E is a binary event and P(H|E) > P(H), i.e., seeing E increases the probability of H, then P(H|¬E) < P(H), i.e., failure to observe E decreases the probability of H. The probability P(H) is a weighted mix of P(H|E) and P(H|¬E), and necessarily lies between the two.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Paolo Freire said, “Washing one’s hands of the conflict between the powerful and the powerless means to side with the powerful, not to be neutral.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If science is a religion, it is the religion that heals the sick and reveals the secrets of the stars.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Only God can tell a truly plausible lie.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Asimov’s “The Relativity of Wrong”:3 When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Why would you pay attention to your own thoughts, if you knew you were trying to manipulate yourself”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“The point of thinking is to shape our plans; if you’re going to keep the same plans anyway, why bother going to all that work to justify it? When”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“To be humble is to take specific actions in anticipation of your own errors. To confess your fallibility and then do nothing about it is not humble; it is boasting of your modesty.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“It’s amazing how many Noble Liars and their ilk are eager to embrace ethical violations—with all due bewailing of their agonies of conscience—when they haven’t spent even five minutes by the clock looking for an alternative.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If the joy of scientific discovery is one-shot per discovery, then, from a fun-theoretic perspective, Newton probably used up a substantial increment of the total Physics Fun available over the entire history of Earth-originating intelligent life. That selfish bastard explained the orbits of planets and the tides.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If there is no black and white, there is yet lighter and darker, and not all grays are the same.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“When you think about nonviolence, you think of Gandhi—not an anonymous protestor in one of Gandhi’s marches who faced down riot clubs and guns, and got beaten, and had to be taken to the hospital, and walked with a limp for the rest of her life, and no one ever remembered her name.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Once you tell a lie, the truth is your enemy; and every truth connected to that truth, and every ally of truth in general; all of these you must oppose, to protect the lie. Whether you’re lying to others, or to yourself.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“If what you believe doesn't depend om what you see, you've been blinded as effectively as by poking out your eyeballs.”
― Eliezer Yudkowsky, quote from Rationality: From AI to Zombies

“Some say that Love, at sight of human ties, Spreads his light wings and in a moment flies.”
― Antoine François Prévost, quote from Manon Lescaut

“Billy didn't need someone to pour him his drinks, he needed someone to tell him that living isn't poetry. It isn't prayer. To tell him and convince him. And none of us could do it because every one of us thought that as long as Billy believed it was, as long as he kept himself believing it, then maybe it could still be true.”
― Alice McDermott, quote from Charming Billy

“A reason or a purpose is a combination of "wants" and "don't wants".”
― Robert T. Kiyosaki, quote from Rich Dad's Retire Young, Retire Rich: How to Get Rich Quickly and Stay Rich Forever!

“La idea de la muerte llega siempre con paso de lobo, con andares de
culebra, como todas las peores imaginaciones. Nunca de repente llegan
las ideas que nos trastornan; lo repentino ahoga unos momentos, pero
nos deja, al marchar, largos años de vida por delante. Los pensamientos
que nos enloquecen con la peor de las locuras, la de la tristeza, siempre
llegan poco a poco y como sin sentir, como sin sentir invade la niebla los
campos, o la tisis los pechos. Avanza, fatal, incansable, pero lenta,
despaciosa, regular como el pulso. Hoy no la notamos; a lo mejor
mañana tampoco, ni pasado mañana, ni en un mes entero. Pero pasa ese
mes y empezamos a sentir amarga la comida, como doloroso el
recordar, ya estamos picados. Al correr de los días y las noches nos
vamos volviendo huraños, solitarios; en nuestra cabeza se cuecen las
ideas, las ideas que han de ocasionar el que nos corten la cabeza donde
se cocieron, quién sabe si para que no siga trabajando tan atrozmente.
Pasamos a lo mejor hasta semanas enteras sin variar; los que nos
rodean se acostumbraron ya a nuestra adustez y ya ni extrañan siquiera
nuestro extraño ser. Pero un día el mal crece, como los árboles, y
engorda, y ya no saludamos a la gente; y vuelven a sentirnos como raros
y como enamorados. Vamos enflaqueciendo, enflaqueciendo, y nuestra
barba hirsuta es cada vez más lacia. Empezamos a sentir el odio que nos
mata; ya no aguantamos el mirar; nos duele la conciencia, pero ¡no
importa!, ¡más vale que duela! Nos escuecen los ojos, que se llenan de
agua venenosa cuando miramos fuerte. El enemigo nota nuestro anhelo,
pero está confiado; el instinto no miente. (...) Cuando huimos como las
corzas, cuando el oído sobresalta nuestros sueños, estamos ya minados
por el mal; ya no hay solución, ya no hay arreglo posible. Empezamos a
caer, vertiginosamente ya, para no volvernos a levantar de vida. Quizás
para levantarnos un poco a última hora, antes de caer de cabeza hasta
el infierno... Mala cosa.”
― Camilo José Cela, quote from The Family of Pascual Duarte

“I already read everything. I read poems and plays and novels and newspapers and comic books and magazines. I read tins in supermarkets and leaflets that come through the door, unsolicited mail. None of it lasts long and it doesn't give me answers. Reading too fast is not soothing.”
― Janice Galloway, quote from The Trick is to Keep Breathing

About BookQuoters

BookQuoters is a community of passionate readers who enjoy sharing the most meaningful, memorable and interesting quotes from great books. As the world communicates more and more via texts, memes and sound bytes, short but profound quotes from books have become more relevant and important. For some of us a quote becomes a mantra, a goal or a philosophy by which we live. For all of us, quotes are a great way to remember a book and to carry with us the author’s best ideas.

We thoughtfully gather quotes from our favorite books, both classic and current, and choose the ones that are most thought-provoking. Each quote represents a book that is interesting, well written and has potential to enhance the reader’s life. We also accept submissions from our visitors and will select the quotes we feel are most appealing to the BookQuoters community.

Founded in 2023, BookQuoters has quickly become a large and vibrant community of people who share an affinity for books. Books are seen by some as a throwback to a previous world; conversely, gleaning the main ideas of a book via a quote or a quick summary is typical of the Information Age but is a habit disdained by some diehard readers. We feel that we have the best of both worlds at BookQuoters; we read books cover-to-cover but offer you some of the highlights. We hope you’ll join us.
