From a BBC interview with a retiring Oxford Don:
Don: "Up until the age of 25, I believed that 'invective' was a synonym for 'urine'."
BBC: "Why ever would you have thought that?"
Don: "During my childhood, I read many of the Edgar Rice Burroughs 'Tarzan' stories, and in those books, whenever a lion wandered into a clearing, the monkeys would leap into the trees and 'cast streams of invective upon the lion's head.'"
BBC: "But, surely sir, you now know the meaning of the word."
Don: "Yes, but I do wonder under what other misapprehensions I continue to labour."
On utility:
culturejammer: you know what pennies are AWESOME for?
culturejammer: throwing at cats
culturejammer: it only costs a single penny
culturejammer: and they'll either chase it, or get hit by it and look pissed off
culturejammer: i now use that system to value prices of things
culturejammer: for example, a thirty dollar game has to be at least as awesome as three thousand catpennies
--bash.org
also from bash.org (made as a reply since I'm already at my 5-quote limit):
<+kritical> christin: you need to learn how to figure out stuff yourself..
<+Christin1> how do i do that
While hilarious, and I upvoted it, I doubt economists would agree with the stated cost of the catpenny game, nor with its comparability to other forms of entertainment.
ETA: and catpenny seems likely to be subject to drastically diminishing returns.
Don't forget to consider the negative utility of an angry cat attacking the catpenny player, which will surely happen after x catpennies.
Anyone going to go looking for x? It would of course have to be statistical distribution, varying with cat age, breed, and so on.
Doesn't catpenny cost less than a penny (in terms of dollars spent)? You can recover most, if not all, of the pennies.
Many people equate tolerance with the attitude that every belief is equally true, and that we should all simply accept this fact and go our separate ways. But I view tolerance as the willingness to come together, to face one another in the same room and hack at each other with claw hammers until the truth finally trickles out from the blood and the tears.

Education is a technology that tries to make up for what the human mind is innately bad at. Children don't have to go to school to learn how to walk, talk, recognize objects, or remember the personalities of their friends, even though these tasks are much harder than reading, adding, or remembering dates in history. They do have to go to school to learn written language, arithmetic, and science, because those bodies of knowledge and skill were invented too recently for any species-wide knack for them to have evolved.

"In the matter of reforming things, as distinct from deforming them, there is one plain and simple principle; a principle which will probably be called a paradox. There exists in such a case a certain institution or law; let us say, for the sake of simplicity, a fence or gate erected across a road. The more modern type of reformer goes gaily up to it and says, "I don't see the use of this; let us clear it away." To which the more intelligent type of reformer will do well to answer: "If you don't see the use of it, I certainly won't let you clear it away. Go away and think. Then, when you can come back and tell me that you do see the use of it, I may allow you to destroy it." GK Chesterton

Thinking is skilled work. It is not true that we are naturally endowed with the ability to think clearly and logically--without learning how, or without practicing....

One of my advisors will be an average five-year-old child. Any flaws in my plan that he is able to spot will be corrected before implementation.
I will maintain a realistic assessment of my strengths and weaknesses. Even though this takes some of the fun out of the job, at least I will never utter the line "No, this cannot be! I AM INVINCIBLE!!!" (After that, death is usually instantaneous.)
I will be neither chivalrous nor sporting. If I have an unstoppable superweapon, I will use it as early and as often as possible instead of keeping it in reserve.
If my advisors ask "Why are you risking everything on such a mad scheme?", I will not proceed until I have a response that satisfies them.
I will see a competent psychiatrist and get cured of all extremely unusual phobias and bizarre compulsive habits which could prove to be a disadvantage.
I will never build a sentient computer smarter than I am.

If [Ayn] Rand really wanted to build an individualist sub-culture, she would have done so in an evolutionarily informed way. If people naturally care about the opinions of others, jumping on people is a good way to get dishonest conformity, but a bad way to get an honest exchange of ideas. Instead, an individualist sub-culture must be built upon tolerance and honesty. I'd suggest three key norms:
- Don't think less of people who sincerely disagree.
- Do think less of people who insincerely agree.
- Do think less of people who think less of people who sincerely disagree.

In our public medical personas, we often act as though morality consisted only in following society's conventions: we do this not so much out of laziness but because we recognize that it is better that the public think of doctors as old-fashioned or stupid, than that they should think us evil.

O Lord our Father, our young patriots, idols of our hearts, go forth to battle -- be Thou near them! With them -- in spirit -- we also go forth from the sweet peace of our beloved firesides to smite the foe. O Lord our God, help us to tear their soldiers to bloody shreds with our shells; help us to cover their smiling fields with the pale forms of their patriot dead; help us to drown the thunder of the guns with the shrieks of their wounded, writhing in pain; help us to lay waste their humble homes with a hurricane of fire; help us to wring the hearts of their unoffending widows with unavailing grief; help us to turn them out roofless with little children to wander unfriended the wastes of their desolated land in rags and hunger and thirst, sports of the sun flames of summer and the icy winds of winter, broken in spirit, worn with travail, imploring Thee for the refuge of the grave and denied it -- for our sakes who adore Thee, Lord, blast their hopes, blight their lives, protract their bitter pilgrimage, make heavy their steps, water their way with their tears, stain the white snow with the blood of their wounded feet! We ask it, in the spirit of love, of Him Who is the Source of Love, and Who is the ever-faithful refuge and friend of all that are sore beset and seek His aid with humble and contrite hearts. Amen.

"We can get very confused, because we think that words must have some secret meaning that we have to figure out. They don't. They are just noises or marks, and they mean whatever experience you have learned to mean by them. People tend to use similar words in similar situations, but unless you have specifically agreed on what the words will mean, in terms of underlying experiences, there's no way to know what another person understands when you use them. The experience you attach to a word when you say it isn't automatically the same as the experience another person attaches to the same word when hearing it."

Rough translation: "What is well understood can be told clearly, and words to express it should come easily."
ETA: it is worth pondering the converse; just because something rolls off the tongue doesn't mean it's well understood. It could be that it's only well-rehearsed.
What the quote is aimed at is work of a supposedly high intellectual caliber, which just so happens to be couched in impenetrable jargon. Far more often, that is in fact evidence of muddled thought, not that the material is "beyond me".
I always saw a close kinship between the needs of "pure" mathematics and a certain hero of Greek mythology, Antaeus. The son of Earth, he had to touch the ground every so often in order to reestablish contact with his Mother; otherwise his strength waned. To strangle him, Hercules simply held him off the ground. Back to mathematics. Separation from any down-to-earth input could safely be complete for long periods — but not forever.

Margaret Mead made a world-wide reputation for herself with her book Coming of Age in Samoa. After visiting the island of Samoa and talking to some teenage girls, she came away convinced that the Puritanism of the American sexual code was cultural artifact. In Samoa, by contrast, sex was freely practiced, with little attention to any niceties. Unfortunately, she was wrong about this, as we learned almost a half a century later, when Derek Freeman, who actually spoke Samoan, went to Samoa and interviewed the now grown women who had been interviewed by Margaret Mead many years earlier. He discovered that they had been putting her on. Decency and sexual restraint were as important to Samoans as to Americans.

'Nash equilibrium strategy' is not necessarily synonymous to 'optimal play'. A Nash equilibrium can define an optimum, but only as a defensive strategy against stiff competition. More specifically: Nash equilibria are hardly ever maximally exploitive. A Nash equilibrium strategy guards against any possible competition including the fiercest, and thereby tends to fail taking advantage of sub-optimum strategies followed by competitors. Achieving maximally exploitive play generally requires deviating from the Nash strategy, and allowing for defensive leaks in ones own strategy. -- Johannes Koelman
...If you think of losing as “not winning,” then when you try to work out why you’ve lost, or (God forbid) why you’re a loser, you’ll tend to focus on the things you didn’t do and the qualities you don’t have. So it goes with any “negative” concept, one that is defined by what it isn’t (think of how “background” = “everything but the foreground” or how valleys are made by the mountains around them).
I think it’s worthwhile to occasionally invert the picture, to see “being a winner” as “not being a loser.” That way you attend to those habits of mind that are h
The activist is not the man who says the river is dirty. The activist is the man who cleans up the river.
-- H. Ross Perot
To take advantage of professional specialization, gains from trade, capital infrastructure, comparative advantage, and economies of scale, the way grownups do it when they actually care, I'd say that the activist is the one who pays someone else to clean up the river.
If people don't realise that the river is dirty and that's causing problems, changing that is valuable work by itself.
The secret of what anything means to us depends on how we've connected it to all the other things we know. That's why it's almost always wrong to seek the "real meaning" of anything. A thing with just one meaning has scarcely any meaning at all.

During a conversation with a Christian friend, during which my apostasy was challenged sincerely and politely but with the usual arguments and style...
Christian: And the Bible tells us that if we have Faith as small as a mustard seed...

Christian: Of course! He's God, God can do anything.

As the mind learns to understand more complicated combinations of ideas, simpler formulae soon reduce their complexity; so truths that were discovered only by great effort, that could at first only be understood by men capable of profound thought, are soon developed and proved by methods that are not beyond the reach of common intelligence.

If we take in our hand any volume; of divinity or school metaphysics, for instance: let us ask, "Does it contain any abstract reasoning concerning quantity or number?" No. "Does it contain any experimental reasoning concerning matter of fact and existence?" No. Commit it then to the flames: for it can contain nothing but sophistry and illusion. --- David Hume

For instance, on the planet Earth, man had always assumed that he was more intelligent than dolphins because he had achieved so much - the wheel, New York, wars and so on - whilst all the dolphins had ever done was muck about in the water having a good time.

There's no scientific reason to believe that we have free will. There's no buffer zone that we've found in any of the physical laws of how the universe works to make room for free will. There's non-determinism; but there's not choice. Choice is the introduction of something, dare I say it, supernatural: some influence that isn't part of the physical interaction, which allows some clusters of matter and energy to decide how they'll collapse a probabilistic waveform into a particular reality.

Artificial intelligences with human interests in mind could use their machine minds to solve human challenges in fields like medicine, physics, chemistry, engineering, politics, diplomacy, biology, sociology, and economics. Being native to the world of computers, they could run complex simulations in mere moments that would take human researchers years to build. Complex, detailed, mathematically accurate simulations could be the default thought mode for artificial intelligences—their “thoughts” could be far superior to our best simulations.
