"if we offer too much silent assent about mysticism and superstition – even when it seems to be doing a little good – we abet a general climate in which skepticism is considered impolite, science tiresome, and rigorous thinking somehow stuffy and inappropriate. Figuring out a prudent balance takes wisdom.”
– Carl Sagan
Everyday words are inherently imprecise. They work well enough in everyday life that you don't notice. Words seem to work, just as Newtonian physics seems to. But you can always make them break if you push them far enough.

An idealist is one who, on noticing that a rose smells better than a cabbage, concludes that it will also make better soup.
-- H. L. Mencken, describing halo bias before it was named
I like the pithy description of halo bias. I don't like or agree with Mencken's non-nuanced view of idealists. it's sarcastically funny, like "a liberal is one who believes you can pick up a dog turd by the clean end", but being funny doesn't make it more true.
Not everything that is more difficult is more meritorious.
I wish I would have memorized this quote before attending university.

Summa Theologica is a good example of what happens when you have an excellent deductive system (Aquinas was great at syllogisms) and flawed axioms (a literal interpretation of the Bible).

Do not accept any of my words on faith,
Believing them just because I said them.
Be like an analyst buying gold, who cuts, burns,
And critically examines his product for authenticity.
Only accept what passes the test
By proving useful and beneficial in your life.
-- The Buddha, Jnanasara-samuccaya Sutra
“A casual stroll through the lunatic asylum shows that faith does not prove anything.”
I apologize for practicing inferior epistemic hygiene. Thank you for indirectly bringing this to my attention. I knew that the quote was commonly attributed to Nietzsche, but I had never seen the original source. It would seem to be a rephrasing of this quote from The Antichrist:
The fact that faith, under certain circumstances, may work for blessedness, but that this blessedness produced by an idée fixe by no means makes the idea itself true, and the fact that faith actually moves no mountains, but instead raises them up where there were none before: all this is made sufficiently clear by a walk through a lunatic asylum.
...when you do have a deep understanding, you have solved the problem and it is time to do something else. This makes the total time you spend in life reveling in your mastery of something quite brief. One of the main skills of research scientists of any type is knowing how to work comfortably and productively in a state of confusion.

(emphasis mine)
Teaching, for me and several other people I know, serves the purpose of reveling in your mastery. In fact, Feynman said it best:
In any thinking process there are moments when everything is going good and you've got wonderful ideas. Teaching is an interruption, and so it's the greatest pain in the neck in the world. And then there are the longer period of time when not much is coming to you. You're not getting any ideas, and if you're doing nothing at all, it drives you nuts! You can't even say "I'm teaching my class."
If you're teaching a class, you can think about the elementary things that you know very well. These things are kind of fun and delightful. It doesn't do any harm to think them over again. Is there a better way to present them? The elementary things are easy to think about; if you can't think of a new thought, no harm done; what you thought about it before is good enough for the class. If you do think of something new, you're rather pleased that you have a new way of looking at it.
Teaching helps me a lot in this respect, because I become very insecure sometimes when I do my research.

......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 mig

In questions of this appalling magnitude, I find the best way to "overcome bias" is often to find perspectives which seem to make each answer obvious. Once we recognize that both A and B are obviously true, and A is inconsistent with B, we are in the right mindset for actual thought.

It’s not a good idea for members of the faith-based community like Hitchens to proclaim things like: Science proves we’re all genetically equal, so therefore you shouldn’t be beastly toward people of other races. The obvious flaw in this strategy is that eventually people will figure out that you are lying about what the science of genetics says, and therefore, by your own logic, that discredits the perfectly valid second half of your assertion.

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.”
–Elizabeth Anscombe, [An Introduction To Wittgenstein’s Tractatus](http://www.archive.org/details/introductiontowi009827mbp) (1959); apropos of a recent Scot Sumner blog post
Another great quote by Sumner in that same post:
The Great Depression was originally thought to be due to the inherent instability of capitalism. Later Friedman and Schwartz blamed it on a big drop in M2. Their view is now more popular, because it has more appealing policy implications. It’s a lot easier to prevent M2 from falling, than to repair the inherent instability of capitalism. Where there are simple policy implications, a failure to do those policies eventually becomes seen as the “cause” of the problem, even if at a deeper philosophical level “cause” is one of those slippery terms that can never be pinned down. [Bold added]
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.
~Desertopa, TVTropes Forum
There are types of valid evidence that aren't scientific. In particular science is also partially a social process, whereas you trying to find the truth for yourself is not.
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.

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.
Lance Parkin, Above us only sky
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. I want to carve a primer on cosmology in gold letters on a mountain, entitled something in all caps along the lines of "HERE IS THE GLORY OF HUMANKIND".
It survived as the working model twenty-five times longer than the four hundred years we’ve understood the Earth goes around the Sun.
Is it excessive nitpicking to point out that the daily disappearance and reappearance of the Sun has to do with the Earth's rotation on its axis, not its rotation about the Sun? (Probably not, as the first comment on Parkin's blog posting points out the same.)
The truth is common property. You can't distinguish your group by doing things that are rational, and believing things that are true.
Paul Graham, Lies We Tell Kids

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 Reall
"A Confucian has stolen my hairbrush! Down with Confucianism!"
-GK Chesterton (on ad hominems)
As in the Roman empire age, the theoretical concepts, taken out of the theories assigning their meaning and considered instead real objects, whose existence can be apparent only to the initiated people, are used to amaze the public. In physics courses the student (now unaware of the experimental basis of heliocentrism or of atomic theory, accepted on the sole basis of the authority principle) gets addicted to a complex and mysterious mythology, with orbitals undergoing hybridization, elusive quarks, voracious and disquieting black holes and a creating Big Bang: objects introduced, all of them, in theories totally unknown to him and having no understandable relation with any phenomenon he may have access to.
Lucio Russo, The Forgotten Revolution: How Science Was Born in 300 BC and Why it Had to Be Reborn
Some people will always have to take most of natural science on authority. Sure you can make that sound bad, but to me it sounds like "children take 9*9=81 on authority! spoooooky."

"A “lie-to-children” is a statement which is false, but which nevertheless leads the child’s mind towards a more accurate explanation, one that the child will only be able to appreciate if it has been primed with the lie."

We made our oath to Vavilov
We'd not betray the solanum

To our own pangs of starvation
"When The War Came", by The Decemberists
(from memory, will fix any errors later)
http://en.wikipedia.org/wiki/Nikolai_Vavilov
"While developing his theory on the centres of origin of cultivated plants, Vavilov organized a series of botanical-agronomic expeditions, collected seeds from every corner of the globe, and created in Leningrad the world's largest collection of plant seeds. This seedbank was diligently preserved even throughout the 28-month Siege of Leningrad, despite starvation; one of Nikolai's assistants starved to death surrounded by edible seeds."
A few Google searches resolved this question for me, and proved very interesting besides. Vavilov was a Soviet botanist focused on the cultivation of efficient seeds to mitigate hunger. In World War Two, Vavilov's Leningrad seedbank came under siege by the Nazis, who apparently wanted to steal/destroy the seeds. Considering the supplies vital to Russia's long-term survival, several of the scientists swore oaths to protect the seedbank against German forces, starving foragers, and rats.
They succeeded in doing so. The scientist-guards were so loyal that many of them died of starvation despite being in a facility full of edible seeds, as well as potatoes, corn, rice, and wheat. The seedbank endured the siege and was replenished after the city was liberated.
Vavilov himself did not live to see the victory of his researchers, as he had been sent to a camp thanks to his disapproval of the scientific fraud of Lysenkoism and died (ironically, of malnutrition) before the war ended.
I replied as follows: "What would you think of someone who said, "I would like to have a cat, provided it barked"? [...] As a natural scientist, you recognize that you cannot assign characteristics at will to chemical and biological entities, cannot demand that cats bark or water burn. Why do you suppose that the situation is different in the "social sciences?"
-- Milton Friedman
There are valid quibbles and exceptions on both counts. Some breeds of cats make vocalizations that can reasonably be described as "barking", and water will burn if there are sufficient concentrations of either an oxidizer much stronger than oxygen (such as chlorine triflouride) or a reducing agent much stronger than hydrogen (such as elemental sodium).
In the general case, though, water will not burn under normal circumstances, and most cats are physiologically incapable of barking.
The point of the quote is that objects and systems do have innate qualities that shape and limit their behaviour, and that this effect is present in social systems studied by economists as well as in physical systems studied by chemists and biologists. In the original context (which I elided because politics is the mind killer, and because any particular application of the principle is subject to empirical debate as to its validity), Friedman was following up on an article about how political economy considerations incline regulatory agencies towards socially suboptimal decisions, addressing responses that assumed that the political economy pressures could easily be designed away by revising the agencies' structures.
I do not pretend to start with precise questions. I do not think you can start with anything precise. You have to achieve such precision as you can, as you go along.
Bertrand Russell
Part of the reason atheism looks the way it does now, and is so lacking in warm fuzzies like "Love and Completeness are Your Spiritual Right," is because it is a refuge for people who think warm fuzzies are bullshit.
Every age has its own outlook. It is specially good at seeing certain truths and specially liable to make certain mistakes. We all, therefore, need the books that will correct the characteristic mistakes of our own period. And that means the old books.

"However," replied the universe,
"The fact has not created in me

He lifted a hand, his index finger pointing upward. "How many fingers am I holding up?" I paused for a moment, which was more consideration than the question seemed to warrant. "At least one," I said. "Probably no more than six"

...The problem with "electability" is that it requires voters to set aside their own feelings on the basis of what they think other people will think in a general election months in the future. The problem with this is that people are generally bad at predicting what other people will think and feel and are lousy at predicting the future. As a result, voters in primaries who focus on electability either vote based on regurgitated popular wisdom of the moment, or on an assumption that other people won't respond to the same things that they respond t
Am I sure that there is no mind behind our existence and no mystery anywhere in the universe? I think I am. What joy, what relief it would be, if we could declare so with complete conviction. If that were so I could wish to live forever.

Thornton Wilder, The Ides of March.
Most people you know are probably weak skeptics, and I would probably fit this definition in several ways. "Strong skeptics" are the people who write The Skeptics' Encyclopedia, join the California Skeptics' League, buy the Complete Works of James Randi, and introduce themselves at parties saying "Hi, I'm Ted, and I'm a skeptic!". Of weak skeptics I approve entirely. But strong skeptics confused me for a long while. You don't believe something exists. That seems like a pretty good reason not to be too concerned with it.
Edit: authorial instance specified on popular demand.
The next sentence is
It's not like belief in UFOs killed your pet hamster when you were a kid or something and you've had a terrible hatred of it ever since.
Skeptics will tell you that yes, it did. Belief that the Sun needs human sacrifices to rise in the morning killed their beloved big brother, and they've had a terrible hatred of it ever since. And they must slay all of its allies, everything that keeps people from noticing that Newton's laws have murder-free sunrise covered. Even belief in the Easter bunny, because the mistakes you make to believe in it are the same. That seems like a pretty good reason to be concerned with it.
Indeed. In fact there's a website: What's the Harm? that explains what damage these beliefs cause.
I don't know if there's enough of a specific, meaningful claim there for me to disagree with, but Yvain-2012 probably would not have written those same words. Yvain-2012 would probably say he sometimes feels creeped out by the levels of signaling that go on in the skeptical community and thinks they sometimes snowball into the ridiculous, but that the result is prosocial and they are still performing a service.

Sun Tzu said it better; VI, 'Weak Points and Strong':

- An army may march great distances without distress, if it marches through country where the enemy is not.
- You can be sure of succeeding in your attacks if you only attack places which are undefended. You can ensure the safety of your defense if you only hold positions that cannot be attacked.
- Hence that general is skillful in attack whose opponent does not know what to defend; and he is skillful in defense whose opponent does not know what to attack.

These evils, however, are due to a very different cause—the wickedness of human nature.
--Aristotle
What interest, zest, or excitement can there be in achieving the right way, unless we are enabled to feel that the wrong way is also a possible and a natural way, — nay, more, a menacing and an imminent way? And what sense can there be in condemning ourselves for taking the wrong way, unless we need have done nothing of the sort, unless the right way was open to us as well? I cannot understand the willingness to act, no matter how we feel, without the belief that acts are really good and bad.

Lack of experience diminishes our power of taking a comprehensive view of the admitted facts. Hence those who dwell in intimate association with nature and its phenomena grow more and more able to formulate, as the foundations of their theories, principles such as to admit of a wide and coherent development: while those whom devotion to abstract discussions has rendered unobservant of the facts are too ready to dogmatize on the basis of a few observations.

While this quote isn't directly about rationality, it reminds me a good deal of Tsuyoku Naritai!.

The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly; who errs and comes short again and again; because there is not effort without error and shortcomings; but who does actually strive to do the deed; who knows the great enthusiasm, the g
We are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield.

But, above all, it is expected that the attention of instructors to the disposition of the minds and morals of the youth under their charge will exceed every other care; well considering that though goodness without knowledge is weak and feeble, yet knowledge without goodness is dangerous, and that both united form the noblest character, and lay the surest foundation of usefulness to mankind.

Nominal essences are all the essences that science needs, and some are better than others, because they capture more regularity in nature.
To explain: a "nominal essence" is just an abstract idea that humans have decided to use to pick out a particular type of thing. This is contrasted with a more Aristotelean view of essence.
"People are stupid; given proper motivation, almost anyone will believe almost anything. Because people are stupid, they will believe a lie because they want to believe it's true, or because they are afraid it might be true. People's heads are full of knowledge, facts, and beliefs, and most of it is false, yet they think it all true. People are stupid; they can only rarely tell the difference between a lie and the truth, and yet they are confident they can, and so are all the easier to fool." -- Zeddicus Zu'l Zorander from the book "Wizard's first rule" by Terry Goodkind.
