Rednecks versus Progressives

Out in rural northeastern Pennsylvania, I run into a fair number of rednecks. Many of them are way too free with their use of the "N-word."

But if they ran across an actual black person waving for help by his broken-down car along the side of Route Six, many of them would stop to help, and even let the driver use their cell phone to call a friend or spouse.

In gentrified Brooklyn, I run into boatloads of progressives. None of them ever, ever would use the "N-word."

But in many cases, if a black person has broken down along the side of Fourth Avenue, and he is blocking their way to the buy-one-get-one-free sale on miso-infused kale chips at the Park Slope Co-op, the black fellow better be ready to jump for the curb.

Question authority

One of the silliest posters seen in the halls of our educational establishments. You're supposed to take it on the authority of your teacher or professor that you ought to "question authority"!

In fact, to become educated at all, you must except the fact that all sorts of people are authorities in subjects in which you are not yet (and perhaps never will be) an authority. When I hire a student finishing his PhD as my math tutor, I must recognize that he has an authority discussing mathematics that I have not, otherwise the hiring of him is completely pointless.

Patriarchy? What Patriarchy?

"However, what I kept saying in Sexual Personae is that equality in the workplace is not going to solve the problems between men and women which are occurring in the private, emotional realm, where every man is subordinate to women, because he emerged as a tiny helpless thing from a woman’s body. Professional women today don’t want to think about this or deal with it." -- Camille Paglia

"The same, of course, is true of the colossal architecture which we call infant education: an architecture reared fully by women. Nothing can ever overcome that one enormous sex superiority, that even the male child is born closer to his mother then to his father. No one, staring at that frightful female privilege, can quite believe in the quality of the sexes." -- G. K. Chesterton, What's Wrong with the World, p. 97

Chesterton goes so far as to argue that feminism represents a complete victory for the male in the battle of the sexes: females have (almost) completely surrendered this enormous advantage. As someone put it at a conference I attended, American women have abandoned the unimportant task of raising and molding the views of the next generation of human beings so that they can do truly important things, like working as assistant human resources director at a marketing firm.

Warring Protestant Sects

"Thus, mankind has a nearly all places in seen that there is a soul and the body as plainly as that there is a sun and moon. But because a narrow Protestant sect called Materialists declared for a short time that there was no soul, another narrow Protestant sect called Christian Science is now maintaining that there is no body." -- G. K. Chesterton, What's Wrong with the World, p. 95

A link between increased immigration and increased crime?

While researching the cause of the apparent (as Shonk noted, it may be an artifact of bad stats) spike in the homicide rate in the early 1900s, the tremendous immigration of that first decade popped out as a possible cause. I googled to find out what has been said about that, and discovered papers like this.

What is interesting is that researchers have been purporting to answer the question of whether a high rate of immigration might lead to a surge in crime, but in fact seem to be answering the question "Are immigrants more likely to be criminals than the native born?" The paper linked to above discusses earlier studies, and they all seem to have proceeded in the same way, by examining incarceration rates for immigrants versus natives, to see if immigrants are more likely to be criminals.

But that is only one possible way in which a high immigration rate might cause a high crime rate. And that worry should not be discounted: for instance, if the United Kingdom discovered that hordes of American police officers were migrating there, they might want to close the border.

However, there is an entirely different vector of disturbance by which an increase in immigration might cause an increase in crime: there are culture-specific customs for smoothing over conflicts before they turn violent, and natives and recent immigrants are not likely to share those customs.

Let me share a memory: it was my first weekend living in London. At my local pub, I met a Jamaican bloke. After we talked for a while, he said, "I'm going to a dance club: why don't you come along?" It seemed only polite to acquiesce, and so off we went in a cab to God knows where.

I found myself in a West Indian night club in which I was just about the only white chap. At one point, as I stood in line to get a drink, a dread next to me informed me, "M' rolling a spliff: don't bump me!"

Well, not ten seconds later, a very drunk patron crashed into me, throwing me... you guessed it, right into the dread. Knocking his half-rolled spliff to the floor. He immediately glared at me, and violence was in the offing.

Luckily, I had spent a lot of time the previous decade-and-a-half around Jamaicans, so instead of trying to explain how "It's not my fault," I looked him in the eye and said, "I'm buying your drinks tonight."

"Cool, cool," he replied, and all was fine.

But if this had happened to me a fifteen years earlier, I almost certainly would have responded differently, and probably would have found myself on the floor soon thereafter, perhaps digesting a bullet.

In the "inability-to-peacefully-resolve-conflict" model of increased immigration leading to increased crime, immigrants need not be more criminally inclined than the native-born: they might even be less so. And the incarceration rates for immigrants and the native-born need not differ: instead, they would both rise together, as conflicts that, had they involved two members of either culture, would have been resolved peacefully, instead escalate into violence through mutual misunderstanding.

It is obvious to me that some problems of this sort will arise whenever culturally different populations newly mingle. How pervasive they are is an empirical matter which I haven't researched: but, it seems*, neither have the people seriously studying this area.

* I am just going but what I read in that one paper linked to above, but, as I mentioned, the authors cite earlier studies, and those seem to use the same method. However, if I wanted to make a blanket statement about this, and remove the "seems," I would have to do much more research.

One Place Mises Went Very Wrong, and Marx Was Correct

Mises held that labor is (almost) always something to be avoided in life, that it has disutility, and that the only point of it is to be able to purchase consumer goods. Interestingly, he recognized an exception: himself. He didn't dislike his work; in fact, he lived for it. So he created a separate category of human being to explain this: the creative genius.

But the truth about labor is that life is incomplete without it: everyone needs meaningful work in their life:

"As a former Marxist, his analysis always held labor, particularly when self-directed or done voluntarily in cooperation with others, in high esteem because of the ethic of responsibility it produced. Work wasn’t, or shouldn’t be, just a means to put food on the table or a roof over your head. Rather it provided meaning, dignity, and moral instruction, something not found by repeating mind-numbing tasks over and over at someone else’s direction."

Contemplate the history of homicide in the US



(Hat tip to Noah Smith.)

What is striking to me here is this weird double-humped shape and the huge variation in the amount of murder. Look at the spike from 1900 - 1934: the homicide rate went up about ten times! In fact, in the first decade of that period, it rose about five times. Prohibition can explain some of the rise in the 1920s, but clearly the real lift-off happened well before that: so what caused that rise?

Also of note: the "everything is getting better in every way" folks point to the recent drop in homicide as evidence supporting their thesis. But if you run your trend line back to 1900, that's not going to work, is it?

There's no third way?

Mises famously contended that there is no third way between socialism and laissez faire. This was an odd contention on his part, since we'd also have to say that according to him we've always been on a third way: pure socialism is not possible (I think Mises was right about this) and we have never had a pure market economy (also, I think, not possible).

Now, Mises was terribly wrong about some things, but he certainly wasn't stupid, so: how did he reconcile these two seemingly disparate ideas?

(I am thinking about this as I begin my research on distributism.)

Can you use them old U. S. Blues?

"that an Empire whose heart is failing should be specially proud of the extremities, is to me no more sublime a fact than that an old dandy whose brain is gone should still be proud of his legs." -- G. K. Chesteron, What Is Wrong with the World, p. 52

And that statement is totally subsumed by philosophy

Someone on my Facebook feed, who seems to be a fairly clever person (but not very wise), posted an essay in which she wrote, "Philosophy has now been totally subsumed by computer science."

We come upon this sort of foolishness regularly: before computer science, philosophy was going to be totally subsumed by the physical sciences. It may be instructive to look at a couple of the problems with a view like this.

First of all, her statement itself is quite obviously not a finding of computer science! Computer science doesn't even contain a category called "philosophy," and so also can't contain any statements about philosophy. Computer science studies algorithms, and there is no possibility that the study of algorithms, however wonderful or brilliant those algorithms are, can reveal anything about subject A being subsumed by subject B, since computer science knows nothing of "subjects" or what it might mean for one to "subsume" another. In fact, the only subject that might be capable of making such a claim about two other subjects is... philosophy.

Secondly, her claim is based on some wooly notion that "the universe is an algorithm." On the face of it, this is sheer babble. What in the world does it mean to say that a beautiful sunrise, a woman giving birth to a child, the death of Cicero, a wolf eating a lamb, Van Gogh's "Starry Night," and the firebombing of Dresden are all "an algorithm"? Were the screams of the children being gassed at Auschwitz a for loop? The Mongols sweeping across the steppes an if statement?

But if there is any sense to her statement, just which subject might be fit to evaluate what that sense might be? Could it be... philosophy?


Marriage

"The joy of battle comes after the first fear of death; the joy of reading Virgil comes after the boredom of learning him; the glow of the sea-bath comes after the icy shock of the sea bath; and the success of the marriage comes after the failure of the honeymoon... The whole aim of marriage is to fight through and survive the instant when incompatibility becomes unquestionable. Freeman any woman, as such, are incompatible." -- G. K. Chesterton, What's Wrong with the World, pp. 36-37

The Chicken and the Egg

"Leaving the complications of the human breakfast table out of account, and an elemental sense, the egg only exists to produce the chicken. But the chicken does not exist only in order to produce another egg. He may also exist to amuse himself, to praise God, and even to suggest ideas to a French dramatist. Being a conscious life, he is, or may be, valuable in himself." -- G. K. Chesterton, What's Wrong with the World, p. 14

Notice how Richard Dawkins deliberately tries to invert this natural hierarchy: he claims we conscious beings only exists as vehicles for our genetic material! This spiritual state is what is meant by "demonic possession."

Just a Gigolo...

A final thought (I hope) on the current shibboleth of asserting, generally without any relevance to the discussion at hand, that humans are "just another ape," or that some topic "strains our ape brains."

I am not a person who entertains any doubts that our ancestors were apes. Nor do I entertain any doubts that the literary ancestors of Anna Karenina were account books at temples and palaces, which seem to have been the first type of written document.

But it is pretty silly to say that, therefore, "Anna Karenina is just another account book."

Distributism

I was recently asked to give a talk to the Radcliffe Alumni Association on the topic of inequality in America. "We'd like," they said, "for you to give us the libertarian perspective on this issue."

"Well," I told them, "my own position is actually probably more distributist. But here's is my colleagues contact info..."

However, she turned them down. And so they came back to me and said, "Well, we'd love to get the distributist perspective on this topic!"

So, now, having put my foot in it, I've got to learn something about distributism!

Just warning you about what is coming up in this space. I'm starting on Chesterton tonight.

Nerd Narcissism

Noah Smith displays typical nerd narcissism with this: "Movies like Revenge of the Nerds depicted nerds - people who liked to use their brains..."

As if carpenters, basketball players, and shopkeepers succeed with their brains turned off!

I dare say that to succeed as a player in an NBA basketball game requires far more "brainpower" than does, say, writing decent computer code, or modeling financial flows. The latter activities tap a *very* specialized sort of brain function: manipulating formal, symbolic expressions. The former involves processing, in real time, a myriad of physical and interpersonal interactions. Think about this: which is it easier to program a computer to do, simplify an algebraic equation or lead a 3-on-2 fast break against two NBA defenders and choose the right pass or shot in tenths of a second?

LeBron James "uses his brain" far more than the average academic.

The garbage can of the universe

Lots and lots of people will tell you that heliocentrism was disturbing when it was first being debated because it "displaced humanity from the center of the universe."

But when I ask actual historians of science about this, they say there is just no evidence for this at all. Here's is yet more testimony to this effect: the center of the universe was it cesspit, and at the very center was hell and the demons: the very worst place to be of all! To get out of the center was a promotion.

Plato did not have "doctrines"

Here:

"First, in his Seventh Letter, Plato denies that the tyrant of Syracuse, Dionysius II, and his pseudointellectual courtiers could have known that about which he is serious (περὶ ὧν ἐγὼ σπουδάζω). They could not have understood it, “For there is no writing of mine about these things, nor will there ever be. For it is in no way a spoken thing like other lessons (ῥητὸν γὰρ οὐδαμῶς ἐστιν ὡς ἄλλα μαθήματα) . . . ” (341c1-6). This means not that Plato’s serious insights are secrets that, perhaps, could be divulged esoterically but, rather, that they are ineffable, impossible to encapsulate in either oral or written speech. Accordingly, we must not expect to find propositional truths about ultimate realities in any Platonic text."

Strauss got this wrong in thinking that the fact Plato noted that he could not express his deepest insights in his dialogues meant that he had some "esoteric" teaching that was too dangerous to reveal. No:

The Tao that can be spoken is not the eternal Tao
The name that can be named is not the eternal name
The nameless is the origin of Heaven and Earth
The named is the mother of myriad things

Thus, constantly free of desire
One observes its wonders
Constantly filled with desire
One observes its manifestations

These two emerge together but differ in name
The unity is said to be the mystery
Mystery of mysteries, the door to all wonders

Or, as another great mystical philosopher wrote: "Whereof one cannot speak, thereof one must be silent."

In fact, actual thought is *never* linguistic

One picks up in this learning a second language, precisely when one realizes that it is only when one stops translating words into other words that one is really "thinking in the new language."

A friend once told me, "I could read Hebrew very well, without knowing it." When asked what he meant, it turns out that he could pronounce Hebrew just fine, when required to do so at synagogue, without having any idea what he was pronouncing meant. But he was saying all the words correctly, and if language is thought, he must have been thinking! Clearly, there is something else behind the words one "gets" once one understands the language. And that can't be just more words, or we have an infinite regress. That something else is what Frege called the sense of an expression.

Je ne sais pas

The French construction ne X pas has an interesting history. Originally, it was apparently popular in expressions like "Il ne marche pas": "He doesn't walk a step." The word 'pas' meant, literally, 'step.'

But then it "leaked" into other expressions, such as "Il ne mange pas": "He doesn't eat (a step?)." Finally, 'pas' displaced the "true" negative from the sentence completely, so today one can simply say "Il mange pas": literally, "I eat a step."

A Weird Empire

I've always found the French intervention in Mexico in the 1860s to be a bizarre episode in history. Did Napoleon III really think this would work?

In any case, I was describing the Second Mexican Empire to my wife tonight. I said, "Of course, the only reason the French could get away with this was the American Civil War. The Monroe Docrtine would have meant that France's moving troops into an independent country in the Americas was a cause for war, except that half of America was already fighting the other half, so we were really in no position to fight France as well."

I paused for a moment, and then added, "Although, of course, that fact wouldn't have stopped everyone on Fox News from condemning Lincoln as 'weak' and possibly a French-allied traitor if he had failed to do so."

Hmm... Now How in the World Could We Test That?

If you are teaching architects in an undergraduate program, you probably can't test them by having them design a real building. Likewise, a professor of economics can't get a student to go run the Fed for a week, or advise a major investment bank. Your civil engineering students may not get to erect an actual bridge as their final.

But I am pretty sure most places is with a computer science department have computers, and programming languages installed on those computers, so what is the puzzle here? You want to see if your student understands bubble sorts? Have her write a bubble sort!

A Real Puzzler

The secular often bring up statistics showing that people in the wealthiest countries are not very religious. These are presented with a smug grin: "Once people start to climb out of poverty, they abandon that religious nonsense!"

Because, you see, no Christian could possibly explain the fact that people who have set their hearts on the pursuit of worldly goods could lose their souls.

Honk for Shonk

A nice interview with our frequent commenter Shonk.

Explaining Mathematics for the Layperson

I am reading Eli Maor's Trigonometric Delights, a book supposedly aimed at the "intelligent layperson." In it, I find this step in a demonstration to the solution of a problem proposed by Regiomontanus:

((x / a) * (x / b) +1) / (x / b - x / a) = (x / a - b) + (ab / ((a - b) * x))

Now, I have little doubt that this equality is true. ("Little" because mathematicians do make mistakes.) And what maneuvers led from the first expression to the second one may be very obvious to some. But after playing around with each side of the equation for a while and not managing to turn one side into the other, I brought the book to a friend who is just finishing his Master's in mathematical education. He spent about 15 minutes toying with it, and also could not see how to move from one expression to the other.

So, while the equality of these two expressions, again, may be completely obvious to some of my readers, the point I am hoping to make is that it is curious to find the "obviousness" of the equality simply assumed in a book specifically aimed at non-mathematicians.

Now, one explanation of my perplexity here could just be, "Well, Gene, you have no aptitude for mathematics." But I don't think that will wash: I scored 800 on my mathematics GRE, and an 'A' in every college mathematics course I have ever taken.

No, I believe the real issue is that a particular mode of mathematical understanding is focused upon in most mathematical texts, while another is neglected. An example: I was recently watching some lectures on number theory. The lecturer set out to prove that there are infinitely many Pythagorean triples. He offered an algebraic proof -- this one I followed with no problem -- but as I watched, I wondered why he was going about this in such a complicated way: if we simply spin a hypotenuse of length one around a unit circle, it was obvious to me that every time the length of the other two legs of the right triangle it spawned were rational numbers, we would have a Pythagorean triple, and clearly there must be infinitely many such cases. And even that previous sentence does not really capture what I thought, since it is a verbal formulation of what was a purely visual experience: I could "see" the hypotenuse spinning around the circle, and could "see" that again and again, the other two legs of the right triangle it formed could be measured by rational numbers.

In the very next lecture, it was explained how Pythagorean triples map to "rational points" along the unit circle. I had never even heard of a "rational point" before then, but it is the technical term for one part of a relationship that was obvious to me as soon as I considered the question at hand. "Symbolic" mathematicians go through a whole mess of symbolic manipulation to prove this point, but I could visualize the conclusion they reached as soon as I saw that hypotenuse spinning around.

So, my contention is this: standard mathematical education is (unduly? -- yes, I think so) oriented around symbolic manipulation -- no doubt an important skill! -- and thus poses an unfortunate hurdle to those who "get" mathematics primarily by visualizing what is going on. And this point, of course, ties into earlier posts about "thinking in pictures": many symbolically oriented thinkers seem to assume that all thought is symbolic thought, e.g., "no creature which lacks language (in the relevant sense of 'language') can be said to think or reason in the strict sense." Well, sorry, Temple Grandin, Albert Einstein*, and I all beg to differ.

The advocates of "symbolic mathematics" might very well respond, "OK, your visual and physical intuitions are all well and good, but our symbolic mathematics can prove theorems." However, as Lewis Carroll demonstrated long ago,  every supposedly "formal" proof must ultimately rest on the intuitive understanding of the person expected to accept the proof. There are, after all, infinitely many possible systems of symbol-manipulation rules, and it is only human judgment that can discriminate between the multitudinous hoard of them that produce nonsense, and the much more limited number which produce truth.

UPDATE: Shonk corrected my parenthesizing of the equation above.

* "For example, to begin with, words and language do not play any role in his thoughts. They must be sought for laboriously later." and "Virtually all of these achievements depended upon a very astute form of physical thinking. Einstein then dressed it in mathematical clothing, seeking where ever possible to keep the mathematics as simple as he could."

How Elites Destroy Themselves

Here:

'Young children learn by example, often copying the behavior of adults. I often see youngsters in strollers or on foot with a parent or caretaker who is chatting or texting on a cellphone instead of conversing with the children in their charge. Dr. Steiner-Adair said parents should think twice before using a mobile device when with their children. She suggests parents check email before the children get up, while they are in school, or after they go to bed.

'One girl among the 1,000 children she interviewed in preparing her book said, "I feel like I'm just boring. I’m boring my dad because he will take any text, any call, any time, even on the ski lift."'

My neighborhood is filled with children of the elite who are being raised by indifferent nannies who spend the day pushing them around in strollers while staring at or talking into their phones.

The Curious "Leads to" Argument

Edward Feser here argues against certain philosophical ideas because they "lead to" certain other ideas. In particular, he rejects a Platonic view of form and occasionalism as a way of understanding efficient causation. In arguing against them, he resorts to this sort of thing:

"So, avoiding occasionalism and thus pantheism also requires affirmation of immanent causal power and immanent teleology -- again, Aristotelian efficient and final causes."

But if occasionalism or the Platonic theory of forms are, in fact, true, it is no argument against them to say that they lead to pantheism: that would just mean pantheism is true as well! And in any case, there is no inevitable slide from such views into pantheism. For instance, Berkeley's understanding that the world is God's ideas is not pantheistic: God's ideas are not God! This blog post is my idea, but you can't kill me by shooting it on the server where it resides.

As Collingwood noted in The Idea of Nature, immanence and transcendence are never absolute, and each implies the other. A form completely transcendent would simply be irrelevant to the thing it supposedly forms. But a completely immanent form is not a form at all: it is just the thing itself. To be a form at all, it must in some way transcend the objects it forms. And as Voegelin pointed out, it is wrong to view Plato and Aristotle as expounding doctrines of form: they are both struggling to find verbal expression for the experiences they have undergone. And their differing expressions of the idea of form are a matter of emphasizing different aspects of the forms.

In fact, if Feser pushes his idea of substance actually being a God-indepepndent property to its logical conclusion, it leads to Deism: the world can now run on just fine without God, thank you. But that is not the right reason to reject it: we should reject it because we have a simpler way of understanding how the world works.

When customs have died

"The French fashion -- of parents arranging their children's future -- was not accepted; it was condemned. The English fashion of the complete independence of girls was also not accepted, and not possible in Russian society. The Russian fashion of matchmaking by the officer of intermediate persons was for some reason considered disgraceful; it was ridiculed by everyone, and by the princess herself. But how girls were to be married, and how parents were to marry them, no one knew." -- Leo Tolstoy, Anna Karenina, p. 54

Here's Anna!

On page 69 of Anna Karinena, I finally meet… Anna Karinena! Imagine the reaction of a modern literary agent if given the manuscript like this: "Meanders about for dozens and dozens of pages without even introducing the main character: The writer has no idea what he is doing."

It is amazing how different classic works of literature typically are from the advice given to writers in trade magazines and so forth. That advice comprises recipes for producing a Big Mac, indistinguishable from every other Big Mac except by the packaging.

Worst Progressive of the Week Award

This week goes to E. K. L.'s mom!

She has filed a suit (along with her daughter, E. K. L.) to force the U. S. federal government to draft women as well as men, arguing "“With both males and females available for such roles today, the two sexes are now similarly situated for draft registration purposes and there is no legitimate reason for the government to discriminate against the female class..."

I am only mostly against the draft*: I think if the country was being invaded by a large foreign army, it would be justified. Otherwise, stay all-volunteer. But for or against it, it is hard to see how failing to force someone into a war they want to avoid, where they can easily be killed, is discriminating against them! I would think it is obvious that current draft arrangements discriminate against men (but for a good reason). After all, women can always volunteer for the army: exemption from the draft just means that won't be dragged in against their will. This is a bit like a lawsuit by a kid from Darien complaining that he and his classmates aren't being arrested at the same rate as their counterparts in Bridgeport.

Oh, and Samson, this is a good example of (currently) legal, blatant discrimination: when the Supreme Court upheld the male-only draft in 1981, it was not because it isn't discriminatory: it quite obviously is. The court upheld it because the judges believed that this is valid discrimination. The distinction is important, and nothing to guffaw at: when an NFL team peremptorily dismisses an applicant for a running back position because he has no legs, this is clearly discriminatory, but quite legal. If Google does the same thing with an applicant for a software engineering position, the company may be in big trouble. The first is currently seen as just discrimination, while the second is unjust discrimination.

* Similar to Westley being mostly dead.

If You've Learned Your History of Science from Scientists...

rather than historians of science, well:

"But did you debunk many HistSci myths? Our friends in the STEM fields are nice and all, but their grasp of the history of science tends to be woeful at best and riddled with nonsense more often than not."

And Thony's story above the comment is fun and worth a read.

Blood libel

While the blood libel actually occurred far too often in the Middle Ages, Philip Daileader claims that he has not been able to discover a single instance of a Catholic bishop supporting the charge. Universally, he says, they dismissed the idea as nonsense.

Similarly, when hoi polloi of the People's Crusade attacked Jews in France and Germany, "The Church opposed these attacks, and local clergy often came to the defense of Jews in their community."

Jews suffered a lot at the hands of the common people of Europe through the Middle Ages. Almost always, church officials denounced these episodes and tried to protect the Jews from their attackers.

If Only the Policy Analysts Agreed with Me, as Well as the Climate Scientists

When I noted that even if we are entering a "Little Ice Age," that would not mean global warming theories are false, boy did I get a lot of flak... from some policy analysts. And those are the people who really understand climate science! Here is what some silly climate scientist says:

'"However, Zharkova ends with a word of warning: not about the cold but about humanity's attitude toward the environment during the minimum. We must not ignore the effects of global warming and assume that it isn't happening. “The Sun buys us time to stop these carbon emissions,” Zharkova says. "The next minimum might give the Earth a chance to reduce adverse effects from global warming."'

But what the heck do mere climate scientists know about the meaning of the findings of climate science? 

All Munichs, Nary a Sarajevo

And editor at a conservative website mentioned online that today he had already received four pieces titled "Obama's Munich." With the large number of "Munichs" we have had in the last decade, we should up to about World War VI by now.

It is odd that for people who keep telling us we must "learn from history," in the world of the war hawks there never seem to arise any new "Sarajevos," where an empire is brought low by responding too aggressively to a terrorist attack. Apparently, "Munichs" occur every few months, while Sarajevo will never, ever repeat itself.

Evolution as a substitute for the market?

E. O. Wilson once said of Marxism, "Nice theory, wrong species," by which he was indicating that communism was appropriate for ants, but not for humans.

But ants, like human actors, face optimization problems, so how do these get solved, in a complex society, without market prices? Of course, we do not expect ants to have to deal with changing tastes or technological innovations, which human actors must. But they still face environmental changes: a rainy or dry season, an anteater moving into the neighborhood, an invading foreign colony, and so on.

It occurs to me that for ants evolutionary pressures, over millions of years, have done what we expect markets to do for humans: adjusted the actions of the agents in the system to, if not optimize their efficacy, at least make it usually adequate to the challenges the agents face. (And remember, there are a lot more ants than humans on the planet, so they have done OK.)

This suggests an interesting question: to what extent can evolved cultural practices substitute for markets in producing sufficiently optimized behavior among humans? This is a great research topic for somebody out there, perhaps even for me one day.

Patrick Deneen on Why Corporations Are On-Board with the Sexual Revolution

Here:

"There is a deeper reason for corporate support, however. ­Today’s corporate ideology has a strong affinity with the lifestyles of those who are defined by mobility, ethical flexibility, liberalism (whether economic or social), a consumerist mentality in which choice is paramount, and a 'progressive' outlook in which rapid change and 'creative destruction' are the only certainties."

This point cannot be stressed strongly enough: markets are great things, within limits. But it is absolutely incredible that anyone minimally educated in philosophy could recommend such a deranged idea as "markets without limits," except that such an idea will gain great financial support from corporate sponsors, since such derangements will maximize their corporate profits.

Recently, I noted this point online, and one of the authors of the above deranged work asked me if I had any "arguments" for rejecting such an insane concept as "X without limits." My response, I admit, was a bit snarky, but it pointed that there was a work by one Airy Stotle called "Nick you a makin' me ethics" that might provide such arguments.

Solve your serious human connection problem...

by hiding the fact it exists!

That is the thrust of the new ad campaign for the new Samsung Galaxy S6 Edge: what is terrible about the fact that your are texting instead of watching your daughter's ballet recital is not that you are doing that, but that she caught you! If you are looking at baseball scores when you are supposedly on a date, that is OK: just don't let your date figure that out!

This is how capitalism "fixes" the problems created by capitalism!

Sesame Street Gets B. B. King to Sing Some Bizarre Metaphysics


The usual mistake we see among literate people regarding scripts is to give written language priority over verbal language: e.g., without the letter 'b,' the word 'bird' could not exist. (If you look, you can find many, many real examples of this kind of error: here is one. This is a site for educators, and it forwards the nonsense that "Chinese is a pictorial language": No, no, the Chinese script may be more or less pictorial, but the Chinese script is just a way to represent various languages such as Mandarin and Cantonese: the script is not a language, and there is no such language as "Chinese." And the various languages spoken in China are no more "pictorial" than are English or Russian or Tagalog.)

But the lyrics King sings are far worse: they actually say that the things whose names start with 'b' could not themselves exist without the letter! OK, sure, as adults, we can all dismiss this as a funny way to compose a song about a letter. But this show is intended for little kids, who could easily believe that unless certain letters exist, the actual things whose names that start with that letter in their own language could not exist without that letter: that is just the sort of magical thinking that educators should be trying to dispel, not reinforce!

If I don't have free will...

Please don't write an advice book telling me to just accept that fact. If I don't have free will, I don't have the free will to accept or not accept anything.

And yet almost every writer I have read arguing that
1) humans don't have free will also argues that
2) we will be happier if we accept this fact.
Well, sorry, if 1) is true, we have no choice about 2)!



The black propaganda of Voltaire, Hume, Kant and Twain

'Our gratitude to that Greco-Roman civilization is seldom stinted, but those who came afterward have left castles, cathedrals, Italian and Flemish and Byzantine art, printing, plainsong, and parliaments, not to mention universities. Yet the black propaganda of Voltaire, Hume, Kant, and Mark Twain remains suspended in the air like soot in the old factory towns, while intellectuals crow over the birth of “modernity” like fancied fighting cocks.'

Read the rest.

I Like the Word "Derp"

It acts as a great signal that I never again need to pay the tiniest bit of attention to a single thing said by the person who just used it.

Lost in Translation: "His" and "Her" Have No Italian or French Equivalents in English

Of course, one can fill in an English word wherever one finds 'sa' or 'son' or 'suo' or 'sua,' and vice-versa.

But 'his' means 'something possessed by a third-person of masculine gender,' and 'her' means 'something possessed by a third-person of feminine gender.

French and Italian do not contain such words. Instead, they have words meaning 'something of feminine gender possessed by a third person' ('sua,' 'sa') and 'something of masculine gender possessed by a third person ('suo,' 'son').

It takes a mental shift for an English speaker to be able to comfortably use the French and Italian possessive pronouns, very similar to what it takes to comfortably drive on the other side of the road in the U. K.

Book review tip

Even if the outlet for which you are writing does not want page numbers accompanying the quotes from the book under review, leave them in until the last minute anyway.

That way, if you find a problem with the quote as you are editing, you can go straight to the page from where it came. Furthermore, you may at some point want to rework the material for an outlet that does want page numbers, and you can find them again in your penultimate draft.

Liberalism and Argumentation

A man insists that violence is the only way to settle social questions. When you disagree, he says "let's settle this by a fight." And when you refuse, he says, "I win!"

Substitute "argument" for "fight," and you have the stealth tactic by which liberalism has hollowed out philosophy and undermined common sense for the last two hundred years. As Alasdair MacIntyre notes, liberal argumentation never settles anything: but that's not the point of it. The point is to leave the average person so morally disoriented that they will wind up acquiescing to auctions for babies and so on.

Apprenticeship

Yesterday, I also got to watch my tutor figure out how to prove something that he had, perhaps, been shown long ago, but had long since forgotten. Proofs have often puzzled me: given a statement like "Prove that x is a Y if z(x) is prime" (I'm making that up but it's the right flavor) I would have no idea where to start.

What I saw yesterday is you really don't have to have any idea how the proof itself will start: you start by just writing down everything you know about the problem, and then begin "messing around" with the equations you have. Sooner or later, you (hopefully) will see the "finish line," as my tutor put it, and you will have your proof. Then you can clean things up, and get the concise, knee proves one finds published.

No book has ever indicated to me that proofs are done that way! And this is a very Oakeshottian point (or Polanyian, if you like your case for apprenticeship from a scientist).

Why Are Books of Mathematics Bad at Explaining Math?

OK, so Shonk plus Salman Khan plus my math tutor have convinced me that I put things badly in my initial post on the topic of mathematical education: it is not mathematicians that are bad at explaining math, it is books on mathematics that are bad at explaining math.

An example: I have been going through a few of books on linear algebra, looking for one that I can connect with. They all immediately launch into ways of doing things with matrices: adding them, multiplying them, figuring out their determinants, ways of getting their minors, and so on. But none of them have told me what matrices are, or what they are for, other than brief mentions that we can solve systems of linear equations using them.

The whole exercise was as though I had been taken from deep in the Amazon rainforest, where I had never seen an automobile, and then placed in the front seat of one, with someone who started to explain to me how to manipulate each of the controls before me, without ever telling me what a car is or what it is for. I see I can make little lights blink on the dashboard, but know nothing about traffic or turning. I get that moving that stick in that direction makes that light come on, but I have no idea why I would want or need to know this.

Today I expressed this frustration to my math tutor, and after he spent about 20 minutes going over the topic, I said, "Ah, so matrices are one way of expressing linear transformations of vectors, and matrix multiplication is the way to compose new transformations out of existing ones!"

So, now my question is, is this a secret? Is no one allowed to reveal it in an introductory textbook on linear algebra? Is my tutor going to be punished by the secret brotherhood of linear algebraists for letting this slip out?

I'm with Gauss here

"sin2θ is odious to me, even though Laplace made use of it; should it be feared that might become ambiguous, which would perhaps never occur... well then, let us write (sin θ)2, but not sin2θ, which by analogy should signify sin(sin θ)." -- Gauss-Schumacher correspondence, quoted in Eli Maor, Trigonometric Delights.

This must be one of the worst notational choices in mathematics.

Secular Progressives and Evolution

Secular progressives have a curious relationship with evolutionary theory. On the one hand, secular progressives despise anyone who doesn't accept modern evolutionary theory. (Just to be clear: I think it is the best theory on offer, although, of course, it will be superseded in time.)

On the other hand, they seem to reject many things that evolution has produced:

* Almost everyone known human society has something we can identify as a religion, so an evolutionary theorist ought to suspect this "religion thing" has some adaptive value: but secular progressives generally view it as barbarous nonsense.

* Almost every known society has been patriarchal, so one ought to suspect that, for humans, patriarchy has some adaptive value: but secular progressives hate patriarchy, and want to destroy it.

* Although the number of people involved has varied, almost every human society has evolved some sort of "marriage" institution that connects men with women, not men with men or women with women: yet secular progressives regard any suggestion that this might be "natural" as sheer bigotry.

* Not only most groups of humans throughout history, but many mammals physically discipline their offspring. But secular progressives view even mild physical discipline as "child abuse."

Just to be clear: nothing above should be taken as an argument that progressives are wrong, just that many of their views do not mesh well with their devotion to evolution as a shibboleth.

Most people *can* be above average

At least if the average of which we speak is the mean: "Consider the average number of legs for a human: it’s around 1.999. Almost everyone is above average and no one is average."

By the way, the quote is from a good article rejecting scientism.

Legalize Jaywalking

A nice post from Market Urbanism.

Aristotle in the Middle Ages

"Medieval Scholastics did not mindlessly worship Aristotle nor did they mindlessly accept everything Averroes said." -- Philip Daileader, The High Middle Ages

In fact, there were multiple condemnations of Aristotle's work during the Middle Ages, culminating in a list of two hundred and nineteen Aristotelean ideas that were declared false. This is hardly the attitude of thinkers who "slavishly followed" Aristotle, a claim that is slavishly repeated by those seeking to sully the reputation of that time.

Human action and art

A wonderful passage from Mark Anthony Signorelli over at The University Bookman:
We are too often misled by our study of the history of art, and the unmistakable stories of development it encompasses, to believe that there was something fated or necessary about these developments. We study Giotto’s innovations in modeling the human form, and Massacio’s use of perspective, and trace the development of these techniques through the work of Ucello and della Francesca and Mantegna, and then their apotheosis in the paintings of Leonardo and Raphael. We find the narrative of this period of art so progressive and coherent, so evidently moving in an explicable direction, that we find ourselves almost instinctively assuming there was something fated about this development, that the frescoes of the Stanza della Segnatura were somehow contained, in embryo, in the Holy Trinity at Santa Maria Novella. We are too apt to forget the thousands of conscious, deliberate choices, made by dozens of individuals, which carried these techniques forward. It is a story in which human agency played a central part, continually exercised in the form of practical reasoning, according to which aesthetic ends were achieved through the selection of the stylistic means most appropriate to achieve them. And because this form of rationality played a role in the story, there is room for rational criticism, a criticism that takes as its task the evaluation of those means, those ends, and their proper—or improper—matching.

I'd rather get my exercise other ways: for instance, by paying for it

A few years ago, I was telling a friend about my new apartment. I mentioned it had five half-flights of stairs.

"My God," he said, "that sounds awful."

"No, no," I replied, "It's great exercise."

"I'd rather get my exercise other ways," was his response.

In fact, I knew how he got his exercise: he paid a goodly amount of money for a gym membership, and he would go to that gym four times a week... and use its stair stepping exercise machine for a half-hour!

Similarly, I had a friend who paid someone to push a lawnmower around his lawn, and then paid someone else to push weights up-and-down at their gym.

This is a notable aspect of modern American life: we only feel good about an activity if we are paying a lot of money to "consume" it. To simply have the exact same activity be a natural part of our daily lives is "drudgery."

Do you think marketing might have had something to do with this?

And kudos to Marx: he got a lot of things wrong, but he was spot on in noting the alienation of the worker from his work in modern society.

Why Mathematicians Are Bad at Explaining Mathematics

In mathematics, it is a virtue when a proof is as minimal as possible: one wants to find the fewest assumptions that are necessary to prove statement X, because using unnecessary assumptions may mask the fact that the statement holds in some domain where one of the unnecessary assumptions does not hold.

In my experience, mathematicians, having been (correctly) trained in this minimalist approach to proofs, unfortunately carry it over into their explanations of mathematical concepts, so that they try to explain a concept employing the absolutely minimum amount of explanatory apparatus possible. But what is a virtue in a proof is not necessarily a virtue in an explanation: students can often benefit from logically superfluous stories, examples, counter-examples, metaphors, and so on. Few mathematicians seem to realize that such ornamentation can make an explanation better.

That Law Is Discriminatory!

As I have mentioned, the astonishing number of really foolish things I've heard said in the SSM debate sometimes gets to me. One thing I've heard from SSM proponents on a number of occasions is that a law that allows heterosexuals to marry their partners of choice, but does not allow homosexuals the same freedom, "is discriminatory."

Well, of course it is! So are laws that stop brothers from marrying sisters, parents marrying their children, and those already married from marrying again. Laws that put robbers in jail discriminate between robbers and non-robbers. Laws that fine polluters discriminate against those who pollute.

Any law that doesn't state "Everyone is innocent!" or "Everyone is guilty!" discriminates. The question is always whether it discriminates on a just or an unjust basis. Opponents of SSM recognize that a law allows heterosexual but not homosexual marriages discriminates, and think it does so on a sound basis: male-male or female-female unions, they believe, should not be given legal sanction, just as brother-sister and adult-child unions should not.

To defease their claim, one must show why this discrimination (against same-sex marriages) is not justified. It is ridiculous merely to note that any such distinction is discriminatory.

The ship of Theseus

Watching a sci-fi show involving personalities switching bodies, it occurs to me that things like the ship of Theseus problem occur when we are dealing with conventionally delimited entities, such as "Jim's car." The car has no intrinsic metaphysical connection to Jim; it is only his by the ownership conventions of the society he lives in. But in these sci-fi scenarios where X's memories are "implanted" into Y's body, and X is in a coma or something, the question is not answered by any "closest continuer" criterion or anything like that: persons are metaphysically distinct entities, and the answer to "Who is really X now?" is just the answer to, "Well, where is X now?" (Not to claim that is easy to answer.)

How to Proceed at Generic Programming

I am currently reading From Mathematics to Generic Programming by Stepanov and Rose. It is a very good book that has me thinking hard about how to render my agent system more generic.

In mathematics, there was a process of generalization that moved through things such as:
  • Common measures
  • Natural numbers
  • Integers
  • Rational numbers
  • Polynomials
  • Real numbers
  • Complex numbers
  • Groups
  • Rings
  • Fields
I think it important to note how this happened: no one sat down and devised an abstract algebra of rings and fields, and then said, "So farmers: I think you can derive something from this to measure your fields." No, people started out measuring fields and buildings and so on, and gradually, over a period of thousands of years, abstracted higher-level constructs from these concrete applications.

Similarly in programming, it seems to me that it is rarely a successful strategy to try to start by defining some grand abstraction, and then building one's system around it. Rather, successful generic programming comes from building concrete applications, and then painstakingly seeking out commonalities found in different applications and abstracting them.

Siri has got computers on her mind
