That is an interesting contrast with Spinoza's view that all ideas enter the mind as beliefs, and that mere apprehension is achieved by diminishing something about the idea believed.

comment by gjm · 2009-04-21T11:34:30.835Z · score: 4 (4 votes) · LW · GW

I don't think it's a contrast. The point is that it takes practice to do the necessary diminishing.

Spinoza was ahead of his time: there's more recent psychological research confirming that when you hear a statement -- even if the context makes it clear that no one is seriously telling you it's true -- the effect is to make you believe it more; and that this effect is stronger if you're having to use more of your brain for some other task at the same time. I forget all the details, but I think there was some discussion of this on Overcoming Bias 6-18 months ago (90% confidence interval).

Oh, that's a good point. I was assuming Aristotle was commending people who could hear it without coming to believe it, but it could easily be that he is commending people who diminish their belief rapidly, and acquire a state of mere apprehension.

One disadvantage of having a little intelligence is that one can invent myths out of his own imagination, and come to believe them. Wild animals, lacking imagination, almost never do disastrously stupid things out of false perceptions of the world about them. But humans create artificial disasters for themselves when their ideology makes them unable to perceive where their own self-interest lies.

Ludwig Wittgenstein: 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?

If you don't know about relative motion and inertia, then it does seem like the sun moves around the earth (even when you know, it still looks that way). Prior to the "Copernican" revolution, it was generally thought that our sense experience of everyday life was sufficient to expose the truth to us. Those two things combined make a major roadblock in establishing that the earth rotates.

Now we can fully appreciate that it doesn't even make sense to make an absolute statement either way. If earth is taken to be stationary, then the sun does move around it (interestingly, this was Tycho Brahe's solution to the problem of shifting to a helio-centric view.)

We're descended from the indignant, passionate tellers of half truths who in order to convince others, simultaneously convinved themselves. Over generations success had winnowed us out, and with success came our defect, carved deep in the genes like ruts in a cart track—when it didn't suit us we couldn't agree on what was in front of us. Believing is seeing. That's why there are divorces, border disputes and wars, and why this statue of the Virgin Mary weeps blood and that one of Ganesh drinks milk. And that was why metaphysics and scince were such courageous enterprises, such startling inventions, bigger than the wheel, bigger than agriculture, human artifacts set right against the grain of human nature.

Insofar as I may be heard by anything, which may or may not care what I say, I ask, if it matters, that you be forgiven for anything you may have done or failed to do which requires forgiveness. Conversely, if not forgiveness but something else may be required to insure any possible benefit for which you may be eligible after the destruction of your body, I ask that this, whatever it may be, be granted or withheld, as the case may be, in such a manner as to insure your receiving said benefit. I ask this in my capacity as your elected intermediary between yourself and that which may not be yourself, but which may have an interest in the matter of your receiving as much as it is possible for you to receive of this thing, and which may in some way be influenced by this ceremony.

Yes, this is a reasonable rationality quote. However, can we discuss the idea behind it because it's not entirely clear to me.

If the person maintains that there is any possibility -- as indicated by his "just in case", then is he not, necessarily an agnostic? What is so wrong about choosing the correct word? He doesn't believe in God but believes he could be wrong: he's an agnostic atheist.

To say that you're agnostic about something can mean two things: That you're not 100% certain, or that you're (approximately) 50% certain. If you're using the first meaning, nothing you've said is wrong... but it is extremely pedantic. It's true we can't be 100% certain that there is no God, but it's also true that we can't be 100% certain about any of our beliefs except perhaps mathematical truths. Would you go around saying you're agnostic about the possibility that Obama is Satan in disguise, or the possibility that the keyboard in front of you is actually a specimen of an as-of-yet undiscovered species of animals with keyboard-mimicry capabilities? Of course you wouldn't. So why would you bother mentioning your agnosticism about God?

Of course, there are some people who really are agnostic about God, in the second sense of 'agnostic'. They're wrong, but at least they're not being pedantic.

What annoys atheists like me is those who take advantage of the dual meaning of 'agnostic' to make us look like overconfident fools: They'll say that no one can know "with absolute certainty" that God doesn't exist and that it is therefore arrogant to believe that he doesn't exist. To someone who hasn't come to terms with the inherently probabilistic nature of knowledge, this can sound like a convincing argument, but to the rest of us it can be rather infuriating.

"Agnostic," as used here and as criticized by Adams, is most often a weasel word used by atheists who believe atheism necessarily requires a god-hating, Hitchens-esque attitude towards religion and do not identify with that, or who are afraid to admit to their atheism for social reasons, or out of fear that they are wrong and god will punish them (and that calling themselves "agnostics" instead of "atheists" will somehow prevent god from punishing them, the absurdity of which is Adam's point, obviously.

Interestingly, this is not the original meaning of agnostic. A "gnostic" believes that the question "Is there a god?" is discoverable or knowable. An "agnostic" believes that it is unknowable or undiscoverable. Thus, an agnostic atheist is one who does not believe there is a god and believes we can never (fundamentally, not just practically) know if there is one or not. The person you would describe is just an atheist, and probably a gnostic one.

I think the vast majority of the atheists in this community believe they could be wrong, they just assign a very, very low probability to it, particularly with respect to certain specifications of god.

When the spiritual teacher and his disciples began their evening meditation, the cat who lived in the monastery made such noise that it distracted them. So the teacher ordered that the cat be tied up during the evening practice. Years later, when the teacher died, the cat continued to be tied up during the meditation session. And when the cat eventually died, another cat was brought to the monastery and tied up. Centuries later, learned descendants of the spiritual teacher wrote scholarly treatises about the religious significance of tying up a cat for meditation practice.

This quote is amusing, but it has always made me wonder... if this is a good translation, then did Avicenna really not understand the law of non-contradiction? Because one who denies that p^~p is a contradiction does not necessarily assert that p and ~p are the same.

What does one mean when one denies the truth of ~(p^~p)? I would guess the person means that this statement is not always true, and thus there exists a p for which this statement is false. Which would mean that there is a p for which p and ~p are simultaneously true.

Of course this doesn't mean that the person believes that "to be beaten is the same as not to be beaten", but it's an amusing quote.

I worry far more about the "promising" stock market, particularly the "safe" blue chip stocks, than I do about speculative ventures -- the former present invisible risks, the latter offer no surprises since you know how volatile they are and can limit your downside by investing smaller amounts...

There will always be a large difference between those who'd ask themselves "why won't things work as they are meant to" and those asking themselves "how could I get them to work".

If the designer claims it can get the right answers no matter what you've input into the machine, thus relying on reading your mind, you can know it's just a crude attempt at scamming you.

As this got voted down, perhaps some commentary is in order. This quote is from a juggling forum a long time ago, and is in fact about juggling. But I also read it as a parallel of the twelfth virtue of rationality.

The juggler's task is to entertain his audience, and if he fails, it is futile for him to protest that he can do many tricks. It is not enough to master many techniques. They must be used to achieve the result that the techniques aim at.

The man of science, whatever his hopes may be, must lay them aside while he studies nature; and the philosopher, if he is to achieve truth, must do the same. Ethical considerations can only legitimately appear when the truth has been ascertained: they can and should appear as determining our feeling towards the truth, and our manner of ordering our lives in view of the truth, but not as themselves dictating what the truth is to be.

"The plain consequence is (and it is a general maxim worthy of our attention), 'That no testimony is sufficient to establish a miracle, unless the testimony be of such a kind, that its falsehood would be more miraculous, than the fact, which it endeavours to establish; and even in that case there is a mutual destruction of arguments, and the superior only gives us an assurance suitable to that degree of force, which remains, after deducting the inferior.' When anyone tells me, that he saw a dead man restored to life, I immediately consider with myself, whether it be more probable, that this person should either deceive or be deceived, or that the fact, which he relates, should really have happened. I weigh the one miracle against the other; and according to the superiority, which I discover, I pronounce my decision, and always reject the greater miracle. If the falsehood of his testimony would be more miraculous, than the event which he relates; then, and not till then, can he pretend to command my belief or opinion."

"First Law of Advice: The correct advice to give is the advice that is desired." - Archibald Putt

comment by CronoDAS · 2009-04-18T22:30:59.564Z · score: 5 (7 votes) · LW · GW

In context:

FOUR LAWS OF ADVICE

Learning to give good advice is so important to technologists that special laws of advice have been developed. The first of these is often stated as follows: "The correct advice is the desired advice." However, this form of the law leaves ambiguous whether the recipient wants correct advice or whether the desired advice is by definition the correct advice. A much clearer and completely unambiguous statement is provided by the following version of the First Law of Advice:

The correct advice to give is the advice that is desired.

A classic example of good advice was given to the mayor of Pittsburgh, Pennsylvania, in the fall of 1920. A major city highway, built on the side of a hill, began sliding, a piece at a time, onto railroad tracks below. With every heavy rain, more mud and parts of the road washed down, causing many of the railroad tracks to be unusable. Efforts to remove the mud to keep all tracks operable had been too slow following some of the more massive mud slides.

Several solutions were offered by local engineering and construction firms and by concerned citizens. One was to pave the entire side of the hill to prevent erosion. Another was to build a metal structure to support the road and protect the tracks. All the suggestions would have been quite expensive, causing thoughtful people to wonder how or if the city could pay for the necessary work. Furthermore, no one knew if any of the proposed ideas would solve the problem.

AN EXPERT IS CALLED

The mayor knew he needed good advice. Ultimately, he hired G. W. Goethals as a consultant. Goethals had served as chief engineer for the Panama Canal and had considerable experience with landslides. His expertise was evident not only in his experience, but also in his consulting fee of $1,000 per day - an extraordinary sum at that time.

After only one day of study, Goethals was prepared with his advice and with his bill. His advice to the city was simple: "Let it slide."

The opposition party and one of the newspapers made sport of the city administration for paying so much for this advice. The mayor rightly argued that it was a small price to pay to learn that none of the more expensive proposals would work. The mayor chose to follow this most economical advice and permitted the hill to slide.

Whether technically right or wrong, the consultant's advice was the desired advice. It did not involve construction expenses. Furthermore, any other solution would have been under constant attack from engineering and construction firms whose "solutions" had been rejected in favor of the winning contractor. The desired advice was clearly the correct advice.

This classic example also stands up well in terms of the Second Law of Advice:

The desired advice is revealed by the structure of the organization, not by the structure of the technology.

And it also agrees with the Third Law of Advice:

Simple advice is the best advice.

Another classic example of advice that obeys all three laws was the advice given to the vice president of a petroleum company during the 1920s. The company had discovered a major oil deposit of high quality that could be refined economically into gasoline and other products. There was only one problem. The resultant gasoline had a greenish tint. Because all gasoline at that time was clear, like water, the marketing group believed there would be considerable customer resistance to an impure-looking gasoline.

The production manager submitted his proposal for solving the problem. It called for modernization of the refinery. The company's chief chemist objected on the grounds that there was no proof that refinery modifications would result in a better product. Removing the greenish tint was a difficult chemical problem that had defied every attempt at a solution. The chief chemist, therefore, recommended an expanded research program.

FOR ADVICE, GO OUTSIDE

Rather than adopting either solution, the vice president wisely turned to an outside consultant for advice. The consultant was a chemical engineer of good reputation in academic circles, who had consulted before in the petroleum industry.

He listened to the proposal of the chief chemist and then to that of the production manager. He talked to engineers and managers at the refinery and to chemists in the laboratory. Then he returned to the university for further study. If he were to recommend more experimental work, the chief chemist would be pleased. On the other hand, a recommendation to modernize the refinery was the desired advice of the production manager.

The important thing for the consultant, however, was to determine what advice was desired by the vice president. The vice president did not want to be responsible for choosing either of the proposals already presented. He wanted to avoid responsibility for any decision that would appear to favor either of his subordinates. If such a decision had to be made, it would be best to attribute the decision to an outsider. This, the consultant discerned, was the real reason why he was hired. Even better for the vice president would be a totally different solution that played no favorites.

After several weeks of additional work, the consultant was ready with a uniquely neutral recommendation - one that required neither research work nor modernization of the refinery. His advice to the vice president was simple: "Advertise the color."

The marketing success of the greenish gasoline and the fact that most gasoline is now artificially colored demonstrate once again that the advice found by studying the structure of the organization - not the structure of technology - is the desired advice. It also substantiates the Third Law. Indeed, simple advice is the best advice.

There are other comments above that are just as bad (Goethe, Adams, Casnocha whose statements I generally like, Feynman who statements I almost always dislike) but I will pick on this one.
