The person I think of as "me", the person the world sees, and the person that could be figured out by a very detailed examination of my actions would probably each barely resemble the other. Also, they would shift over quite short timescales as bits of personality are triggered and demoted by context. I can't really claim to be a unitary person, only a unitary brain. So "the real me" is a terribly messy question. Or 1.5 kg of grey goop, depending how it's asked.

Yes, humans try to present themselves as simple, so that others can understand and trust them. But humans really are quite complex. Hence an inevitable divergence between what we are and how we appear must be managed. Hence others can reasonably wonder of how we appear is how we really are.

When I was young, I thought the act of getting older meant, year by year, getting more sophisticated, more hard, cool, and unpitying. Less innocent.

Maybe that was a childish idea of what getting older was about. Maybe adults, mature adults, get more innocent with time, not less. Because the word "innocent" does not mean "naive," it means "not guilty."

Children do small evils to each other, schoolyard fights and insults, not because their hearts are pure, but because their powers are small. Grown-ups have more power. Some of them do great evils with that power. But what about the ones who don't? Aren't they more innocent than children, not less?

On some pitch black mornings, hearing what I knew was a cold wind howling outside, I might think, "Well, it is certainly comfortable in this bed, and maybe it wouldn't hurt if I just skipped practicing to-day." But my response to this was not to draw on something called will power, to insult or threaten myself, but to take a longer look at my life, to extend my vision, to think about the whole of my experience, to reconnect present and future, and quite specifically, to ask myself, "Do you like playing the cello or not? Would you like to play it better or not?" When I put the matter this way I could see that I enjoyed playing the cello more than I enjoyed staying in bed. So I got up. If, as sometimes happened or happens, I do stay in bed, not sleeping, not really thinking, but just not getting up, it is not because will power is weak but because I have temporarily become disconnected, so to speak, from the wholeness of my life. I am living in that Now that some people pursue so frantically, that gets harder to find the harder we look for it.

“Do as I say, not as I do:” this is considered the very motto of hypocrisy. But does anyone believe that having a good character is as easy as wanting it? If virtue is as difficult as other excellences, there must be few or none who are perfectly virtuous. If the rest of us are not even to talk about virtue or express admiration for it, how shall anyone improve? A hypocrite is one who claims virtue beyond what he possesses, not one who recommends virtue beyond what he claims. If a man’s principles are no better than his character, it is less likely to be a sign of an exemplary character than a sign of debased principles.

"I'm writing a book on magic," I explain, and I'm asked, "Real magic?" By real magic people mean miracles, thaumaturgical acts, and supernatural powers. "No," I answer. "Conjuring tricks, not real magic."

Real magic, in other words, refers to the magic that is not real, while the magic that is real, that can actually be done, is not real magic.

comment by sark · 2010-12-21T16:17:09.325Z · score: 0 (0 votes) · LW · GW

This seems to me to be a confusion over senses of the word "real". "Real magic" as opposed to "Not real magic" here is simply used in the analogous sense of "Do you like like me?" vs. "Or do you just like me?". Whether "real magic" can in fact be done did not enter into the mind of the questioner in the above scenario. Hence "real" there is used in the sense of "genuine" instead of "actual".

This is a common pitfall for quotes/aphorisms. Their short length is an incentive for conciseness, but it can also become an end in itself. Hence leading us to tradeoff meaning for superficial features like symmetry, rhyme, etc.

There is a mathematical style in which proofs are presented as strings of unmotivated tricks that miraculously do the job, but we found greater intellectual satisfaction in showing how each next step in the argument, if not actually forced, is at least something sweetly reasonable to try. Another reason for avoiding [pulling] rabbits [out of the magicians's hat] as much as possible was that we did not want to teach proofs, we wanted to teach proof design. Eventually, expelling rabbits became another joy of my professional life.

If all I knew was that the last five spins landed on black, if I had to bet red or black, I'd bet black.

...you have to make a conscious effort to keep your ideas about what you want from being contaminated by what seems possible.This is isomorphic to the principle that you should prevent your beliefs about how things are from being contaminated by how you wish they were.

Isn't this obvious and also arguing against only a straw-man position with respect to intelligence and intellectual skill -- namely that intellectual skill is a function of one variable (intelligence) and that all other factors (such as industriousness & creativity) have no impact on intellectual skill?

It's phrased as if it conveys some deep wisdom, when the reality is that almost all reasonably intelligent people already believe this.

The scope of the Einstein quote is "anyone", and claims that we can infer distrust based on "minor" transgressions. I'd say this is a fairly significant claim, and would be more than just a "small" violation of truth were it found to be false.

That quote touches a sore spot on me due to the recent death of Erik Naggum.

Given the story of his encounter with the psychologist (also in Surely You're Joking, Mr. Feynman!), I'd say he thought so, and ditto with the other fields he mentioned.

The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work.

We all know many things about the world. What form or shape does our knowledge take? We may be able to say some of what we know, though in many people there is a deep and dangerous confusion between what they say and think they believe and what they really believe. But all of us know much more than we can say, and many times we cannot really put it into words at all.

For example, if we have eaten them, we know what strawberries taste like. We have in us somewhere knowledge---a memory, many memories---of the taste of strawberries. Not just one berry either, but many, more or less ripe, or sweet, or tasty. But how can we really speak of the taste of a strawberry? When we bite into a berry, we are ready to taste a certain kind of taste; if we taste something very different, we are surprised. It is this---what we expect or what surprises us---that tells us best what we really know.

We know many other things that we cannot say. We know what a friend looks like, so well that we may say, seeing him after some time, that he looks older or no older; heavier or thinner; worried or at peace, or happy. But our answers are usually so general that we could not give a description from which someone who had never seen our friend could recognize him.

I think it is true relative to the average young folk and the average old folk. To the extent that there is an uncommon skill involved in unlearning falsehoods, we can imagine people who get better at this skill by practice and learning over time. And hence, as it were, "stay young".

I think the point of the quote is not that young folks are more able to unlearn falsehoods; it's that they haven't learned as many falsehoods as old people, just by virtue of not having been around as long. If you can unlearn falsehoods, you can keep a "young" (falsehood-free) mind.

I don't think that's necessarily the thrust of the quote. It doesn't say "to remain youthful, with respect to the ability to unlearn falsehoods, requires unceasing cultivation of this ability". I don't know the context or the intent behind the quote, but it doesn't seem to imply for sure that young people generally have more of this ability than older people.

The only context is that it appears in a set of other sayings of Lazarus Long in the interlude chapters of "Time Enough For Love", later collected into "The Notebooks of Lazarus Long". I've always thought it reasonable to assume that this is Heinlein himself talking. He had more of these aphorisms than could be worked into the dialogue.

Some people through the years accumulate more and more knowledge and beliefs, not all true, and never unlearn any of them. Whatever they acquire, they cling to, and end up as stiff, bitter old folks railing against a world they can no longer deal with. Others retain a lively intellect indefinitely, by always being open to the truth -- that is, to discovering that they were wrong. That is my interpretation of the quote.

According to an old story, a lord of ancient China once asked his physician, a member of a family of healers, which of them was the most skilled in the art.

The physician, whose reputation was such that his name became synonymous with medical science in China, replied, "My eldest brother sees the spirit of sickness and removes it before it takes shape and so his name does not get out of the house."

"My elder brother cures sickness when it is still extremely minute, so his name does not get out of the neighborhood."

[N]ot just our actions and reactions but our very perceptions, what we think we see, feel, smell, and so on, are deeply affected by our mental model, our assumptions and beliefs about the way things really are. In a great variety of experiments with perception, many people, many times over, have shown this to be true. Therefore it is not just fancy and tricky talk to say that each of us lives, not so much in an objective out-there world that is the same for all of us, but in his mental model of that world. It is this model of the world that he experiences. We are not, then starting an impossible contradiction, or using language carelessly, when we say that I live in my mental model of the world, and my mental model lives in me.

I haven't read it, but I have read quite a bit of other things by John Holt.

He is known mainly as a theorist of education (the title of the above-quoted book may be a reference to a teacher trying to plan class activities) but he would probably say that he was interested in learning, and interested in education only inasmuch as it helps or hinders learning. He is the primary initiator of the "unschooling" philosophy of homeschooling.

I have posted some other John Holt quotes elsewhere in this post's thread.

"I’m moved to laughter at the thought of how presumptuous it would be to reject mathematics for philosophical reasons. How would you like the job of telling the mathematicians that they must change their ways…now that philosophy has discovered that there are no classes? Can you tell them, with a straight face, to follow philosophical argument wherever it leads? If they challenge your credentials, will you boast of philosophy’s other great discoveries: that motion is impossible, that a Being than which no greater can be conceived cannot be conceived not to exist, that it is unthinkable that anything exists outside the mind, that time is unreal, that no theory has ever been made at all probable by evidence (but on the other hand that an empirically ideal theory cannot possibly be false), that it is a wide-open scientific question whether anyone has ever believed anything, and so on, and on, ad nauseam?

Lewis held that our common-sense-beliefs have greater initial plausibility than every philosophical argument against them, be it in mathematics ("there are numbers") or metaphysics ("there is time"), philosophy of mind ("there are beliefs"), ethics, etc.

Philosophy can help to find a realiser - a best candidate - for the role of numbers, beliefs, etc., but the price for "losing our moorings" (after g.e. moore), i.e., denying common-sense propositions, is almost always too high.

There is at least one case, of course, where Lewis was willing to pay: modal realism.

At the other end of the spectrum are the opponents of reductionism who are appalled by what they feel to be the bleakness of modern science. To whatever extent they and their world can be reduced to a matter of particles or fields and their interactions, they feel diminished by that knowledge....I would not try to answer these critics with a pep talk about the beauties of modern science. The reductionist worldview is chilling and impersonal. It has to be accepted as it is, not because we like it, but because that is the way the world works.

Yeah... I understand the sentiment, but as someone who delivers those pep talks, I do think, in all seriousness, that the guy's wrong. If we weren't made out of particles we'd be made out of something else. Particles is just the stuff that stuff turns out to be made of. Anyone who has a problem with this has misunderstood something, or their real problem is something else.

For example, it is very depressing that people who die are gone forever. But this is not a matter of them being made out of particles. It would be just as bad if they were made out of freeplegrunge and then ceased to exist forever.

I recently watched your second bloggingheads debate with Adam Frank and the point you make above is one I think you should have stated clearly in that debate. Mr (Prof?) Frank based part of his argument on the feeling of fulfillment that one receives being in a relationship and believing that there is a metaphysical element to the relationship (and similar situations). Yet he does not actually believe that metaphysical element exists...only that the belief has some kind of psychological benefit. The way you addressed your position made it sound like the reductionist view is one in which feelings of fulfillment and "meaning" (a term that I think is fairly weakly defined in these discussions) cannot exist or exist differently. I know this was not your point.

Someone who has a fuzzy warm feeling from a metaphysical belief is still getting warm and fuzzy in a physical world in which their belief is wrong. There is nothing inherent about the nature of the world or knowing things about the nature of the world that precludes feeling satisfied, happy, warm, complete, or fulfilled. Those feelings exist within the substrate of physical material that makes up the world already. As you have pointed out before, those feelings would be all the more genuine and meaningful if they were founded on beliefs that more closely matched the actual working world.

I think in that debate you were approaching this topic somewhat from the side of things.

Although that is true, I think people who believe in freeplegrunge also believe that freeplegrunge implies immortality; indeed, that's the reason they believe in freeplegrunge, although they rarely admit it. So your statement misses the mark a bit; it's not the lack of freeplegrunge people object to, it's the lack of immortality. And that is not only depressing, it really is a property of particles as opposed to freeplegrunge; at least this is true in the minds of freeplegrungists, because of the very strong coupling between their freeplegrunge-belief and their immortality-belief.

I would note that orthodox statistics and the Copenhagen interpretation of quantum theory are just two different manifestations of a single intellectual disease, closely related to logical positivism, which has debilitated every area of theoretical science in this century. The symptoms of this disease are the loss of conceptual discrimination; i.e., the inability to distinguish between probability and frequency, between reality and our knowledge of reality, between meaning and method of testing, etc.

"The reader in search of knock-down arguments in favor of my theories will go away disappointed. Whether or not it would be nice to knock disagreeing philosophers down by sheer force of argument, it cannot be done. Philosophical theories are never refuted conclusively. (or hardly ever. Gödel and Gettier may have done it.) The theory survives its refutation - at a price. Perhaps that is something we can settle more or less conclusively. But when all is said and done, and all the tricky arguments and distinctions and counterexamples have been discovered, presumably we will still face the question which prices are worth paying, which theories are on balance credible, which are the unacceptably counterintuitive consequences and which are the acceptably counterintuitive ones. On this question we may still differ. And if all is indeed said and done, there will be no hope of discovering still further arguments to settle our differences."

On the other hand, precise statements that are somewhere in the vicinity of the truth can be dangerous, because people tend to mistake precision for accuracy, and because modes of reasoning (e.g., formal logic) adapted to precise statements tend to be brittle -- one can deduce very wrong conclusions from slightly wrong premises.

A charitable reading of Smullyan would be that when a precise statement is made, he likes to examine it as closely as its precision allows, to avoid such dangers; and that a vague statement, so far as it's vague, is not worth the trouble of criticizing.

I do not agree with all interpretations of the quote but primed by:

That's not right. It's not even wrong. -- Wolfgang Pauli

I interpreted it charitably with "critical" loosely implying "worth thinking about" in contrast to vague ideas that are not even wrong. Furthermore, from thefreedictionary.com definition of critical, "1. Inclined to judge severely and find fault.", vague statements may be considered useless and so judged severely but much of the time they are also slippery in that they must be broken down into precise disjoint "meaning sets" where faults can be found. So vague ideas cannot necessarily be criticized directly in the fault finding sense. (Wide concepts that have useful delimitations in contrast to arbitrary ill-formed vague ones can be useful and are a powerful tool in generalization. In informal contexts these two meanings of vague overlap).

"As a final practical maxim, relative to these habits of the will, we may, then, offer something like this: Keep the faculty of effort alive in you by a little gratuitous exercise every day. That is, be systematically ascetic or heroic in little unnecessary points, do every day or 2 something for no other reason than that you would rather not do it, so that when the hour of dire need draws nigh, it may find you not unnerved and untrained to stand the test.

You say that your opponent lacks humanity. It's the oldest semantic weapon there is. Think of all the categories of people who've been classified as non-human, in various cultures, at various times. People from other tribes. People with other skin colors. Slaves. Women. The mentally ill. The deaf. Homosexuals. Jews. Bosnians, Croats, Serbs, Armenians, Kurds [...]

But suppose you accuse me of 'lacking humanity.' What does that actually mean? What am I likely to have done? Murdered someone in cold blood? Drowned a puppy? Eaten meat? Failed to be moved by Beethoven's Fifth? Or just failed to have—or to seek—an emotional life identical to your own in every respect? Failed to share all your values and aspirations?

The answers is: 'any one of the above.' Which is why it's so fucking lazy. Questioning someone's 'humanity' puts them in the company of serial killers—which saves you the trouble of having to claim anything intelligent about their views.

I read the quote from Lazarus Long in the original post as an olive branch to his opponents and a rebuke to his friends and allies. There is a concern underlying it that loqi's rebuke completely misses.

First Lazarus Long offers a test of humanity that is open to all. The deaf, the homosexual, the Jew, etc, all may pass Long's test. Read between the lines to find the implicit advice: Learn to cope with mathematics. It is good advice, good enough that it is a dangerous gift to give to ones enemies.

There is a saying in military circles that amateurs talk tactics, professionals talk logistics. An enemy that holds mathematics in contempt will blow off the logistical calculations behind his military campaigns. How many bullets do we need? How long will the march take? How much food do we need? Who cares, let us run at the enemy screaming!

An enemy that cannot cope with mathematics is seldom much of a threat; a friend or ally who cannot cope with mathematics is more dangerous. Simply moving the selector from single shot to fully automatic will let the innumerate comrade shoot off the expeditions ammunition in a matter of minutes, dooming the entire party.

Since the quote is from Lazarus Long we should think space opera. The ship has broken down and rescue is months away. Calculate the rations that let the crew survive. No doubt they are uncomfortably meagre. If too many cannot cope with mathmatics, refuse the unwelcome results of the calculation and insist on too large a ration, all will perish. This dilemma is a modern setting for a dilemma that was common in history. When the crops fail, meagre stocks must be nursed through a hungry winter. The sums are the same. Bryan Caplan captures the modern form of the problem.

Lazarus Long does not fear defeat by subhuman opponents. Why should he? He is sincerely believes that they are inferior. No. He fears being dragged down by his own side, most of who are no better.

Reasonable concerns, but I don't think the "subhuman" terminology captures their meaning in the slightest. I generally don't consider "human" to be synonymous with "useful", "reliable", or "competent".

First Lazarus Long offers a test of humanity that is open to all. The deaf, the homosexual, the Jew, etc, all may pass Long's test.

By "Long's test" you still mean mathematics, right? "May"? Homosexuals "may" have heterosexual sex, deaf people "may" regain their hearing, and so on. Your statement seems to assume the very definition of humanity it's trying to support.

What about that most infamous claim, that women have fewer teeth than men? At first glance, one wonders (as does M.) how such a claim could serve an ideological purpose. How are the interests of men advanced at the cost of women by the belief that they have more bicuspids and molars? But more importantly, M. points out that there is some evidence to suggest that Aristotle's claim about teeth is actually a testament to his careful observation rather than evidence of apriorism in his science. Although the evidence is speculative, there is some proof that the diets of ancient Mediterranean women were deficient in vitamin C and D, deficiencies which resulted in diseases such as scurvy, osteomalacia, and osteoporosis, especially in pregnant and lactating women.5 No one knows exactly what Aristotle saw when he looked into the mouths of Mrs. Aristotle and her friends, but if he consistently saw fewer teeth that would hardly have been implausible given what we know about diet, calcium deficiency, and tooth loss.

Note that since Aristotle was about as close to an empiricist as you'll find those days, and discovered many exciting things about animals through direct observation, it's unlikely that this mistake was due to not having checked.

Treat infinite descent as a working hypothesis, and since all entities turn out to be composite, supervenient, realized, and governed, it emerges that these attributes cannot be barriers to full citizenship in the republic of being. The macroworld, once regained, is not easily lost, even should real evidence for fundamentality arrive.

I googled around for this, and uncovered a rich seam of thought gone mad, including one complete lunatic insisting (in an academic journal, too) that nothing exists but quantum points, which have no relationship whatever to each other (and has also written about the secret rulers of the world in a book that an enthusiastic reviewer describes as more plausible than David Icke). Schaffer doesn't seem to actually take a position on atomism or monism -- here's another paper by him.

None of the material I looked at contained the argument (which convinces me) that the simplest descriptions of reality use complex entities (rocks, people, uranium, etc.), and that all the soul-searching over what really exists is just thought gone wrong.

Richard, a few thoughts and questions: what other people and papers did you look at?

IMO, Schaffer is the most interesting philosopher working in metaphysics today. He has a lot of interesting papers on questions of ontological priority and fundamentality. Well worth exploring, and too complicated to discuss in detail here (here's a link to all of his papers:)

In the end, he says, these are largely empirical questions, and that seems just about right. Many of his own argumets are of this sort (i.e., scientists finding ever deeper levels on the one hand, and entanglement on the other). And to me, his positions in the two papers seem largely consistent. There might be no fundamental level AND nonetheless a priority of the whole.

This quote is rather unclear - I had to look at the original source to determine what it might mean - and equally importantly, it seems rather useless.

There is some tendency - or bias, if you wish - on this site to take reductionism for granted. Schaffer might help here. By reading him we might come to expect, with some probability, scientific findings that point to an infinite descent of ontological levels, and so to the failure of reductionism. His other goal is to argue against a stronger form of reductionism that comes easily with the first: eliminativism in regard to, say, qualia, or beliefs.

I'm not sure your (or his) argument actually addresses popular beliefs. Two points:

  1. Reductionism has been proposed not (merely) because it is intuitive, but because it is supported by the evidence. Starting with particle physics, you really can infer chemistry, thermodynamics, fluid mechanics, solid mechanics, heat transfer, and so on - and you can make correct predictions about when the assumptions used in the latter will break down. (For example: when the channels of fluid flow are comparable in size to the particles.) This is just as would be the case in a reductionistic universe.

  2. Eliminativism is no more implied by reductionism than amorality. If you think that rainbows don't exist once they've been unweaved, you're making a mistake that has nothing to do with science.

I still think it relevant:

ad 1.: that might be so, but it's not all there is to reductionism, at least according to this or that attempt.

ad 2.: that might be so, but it's nonetheless a theory people rather easily catch, along with reductionism. For example: If you take reductionism for granted, and some entity does not easily fit it, then you are seduced into eliminating that entity.

Point taken. Nevertheless, the fact that people draw absurd conclusions from a belief has no bearing on whether that belief should be questioned unless those absurd conclusions are (1) logical, rather than philosophical, inferences, and (2) contrary to evidence. Those conditions do not hold for reductionism (and Dennett, in particular, had a few things to say about "greedy reductionism").

A logical inference is inescapable. If the universe is purely deterministic, then everything that happens tomorrow can be predicted from a complete description of the laws of nature and state of the universe at this exact instant - this is a logical inference. But if the universe is purely deterministic, then the people in the universe might be fully responsible for their acts or they might not - philosophers have drawn both inferences, because the deduction depends on additional premises not stated in the syllogism.

Likewise, the inference from reductionism to the conclusion that ordinary things do not exist - what Dennett called "greedy reductionism", and what you^H^H^Hspuckblase (sorry, didn't look at the names!) offered Schaffer's beliefs as an anodyne to - has been argued, but has also been denied, by philosophers. Its validity depends on other premises, such as what it means to exist.

I don't believe that breaks anything. Tabooing "reductionism", I don't see how infinity of ontological levels (whatever that could mean) is a surprising view. The problem is with mental concepts, thoughts manifested in the rules of the game, a design implemented in terms of the territory happening to also be engraved in its deepest principles.

I'm afraid you sort of lost me after "mental concepts", so the followong might not apply, but: "deepest principles" make no sense in an appropriate (as worked out by schaffer in the paper) account of infinite levels. His idea is that since every level is grounded by AND grounds another level, all entities on all levels are on an equal footing, including mental entities.

I suspected you might pay attention to that detail. The appropriate generalization just says that you don't expect the same laws to apply at different levels (between levels): a concept in a mind (in a brain, that is a system constructed on top/in terms of lower levels) won't obey the same laws as the lower-level stuff from which the mind is built. There is also a nice antisymmetry here: a mind can look at lower levels and organize its thoughts to model them, but lower levels can't do the same to the thoughts in a mind.

The quote, for me, comments on several common themes around here. Probably the strongest connections I make are to updating of priors based on evidence, and to the issue of communication, when the speakers possess different levels of self awareness and rational thinking ability.

Downvoted for improper use of quotation. The comic is successful because it effectively communicates its message by cleverly juxtaposing two panels that are identical except for the implied sex of one character, and one word in the other character's line. To simply quote the second panel out of context doesn't make any sense at all. Linking to the comic does not redeem this mistake---quotes are supposed to be able to stand on their own.
