I don't think Paul Krugman has been at his best lately.  Perhaps, as someone here suggested, the problem is that he's strayed too far from economics, his home base.  Well today he writes about economics, home ownership, and he seems to mess it up.  Unlike many of the people we talk about here, Krugman has shown that he's better than this.  So it's sad to see him write:

But here’s a question rarely asked, at least in Washington: Why should ever-increasing homeownership be a policy goal? How many people should own homes, anyway?

Listening to politicians, you’d think that every family should own its home — in fact, that you’re not a real American unless you’re a homeowner. “If you own something,” Mr. Bush once declared, “you have a vital stake in the future of our country.” Presumably, then, citizens who live in rented housing, and therefore lack that “vital stake,” can’t be properly patriotic. Bring back property qualifications for voting!

Even Democrats seem to share the sense that Americans who don’t own houses are second-class citizens. Early last year, just as the mortgage meltdown was beginning, Austan Goolsbee, a University of Chicago economist who is one of Barack Obama’s top advisers, warned against a crackdown on subprime lending. “For be it ever so humble,” he wrote, “there really is no place like home, even if it does come with a balloon payment mortgage.”

The first question, however jarring, seems to be a legitimate one.  But it ought to be directed at our intuitions about home ownership (that it gives you more of a stake in your neighborhood, etc.).  Instead, Krugman aims this one first at what is clearly a caricature of the advocates of home ownership–one that barely even satisfies its own ridiculousness.

This is really a shame.  It's nice to have one's intuitions challenged.  Krugman could have done this well, had it not been for his George Will style "presumably" argument.

George Will, Straw Man

Not alone

Sometimes I wonder if I labor in solitude.  Then I read this review of George Will's most recent book–which is really just a collection of columns with an introduction:

Has Will lurched leftward? Not at all. As his 1983 book “Statecraft as Soulcraft” indicates, he has long regretted that we have “become a nation wedded to the liberal assumption that the way to deal with passions is to ‘express’ them, to maximize ‘self-expression.’” These sentiments have now led to a sentimentalization of America. By contrast, Will mocks what he sees as a saccharine therapeutic culture in which bus drivers in Scottsdale, Ariz., are referred to as “tranporters of learners” and school receptionists as “directors of first impressions.” What’s more, Will ridicules Thomas Frank’s fatuous “What’s the Matter With Kansas?,” which maintained that Americans vote conservative only because hot-button social issues like abortion and gun-control blind them to their true economic interests. As Will puts it, “It has come to this: The crux of the political left’s complaint about Americans is that they are insufficiently materialistic.”

But these are easy targets, sometimes too easy. When Will issues blanket and tedious denunciations of American universities, he has a penchant for stacking the deck: “Professors, lusting after tenure and prestige, teach that the great works of the Western canon, properly deconstructed, are not explorations of the human spirit but mere reflections of power relations and social pathologies.” But is there anything wrong with a professor aspiring to make a mark in his or her field? Was Will “lusting” for “prestige” when he embarked upon his career as a journalist or was he simply trying to make a success of himself? And to denounce professors as a class is a form of reverse Marxism, no less absurd than depicting all businessmen as intrinsically greedy and corrupt.

Elsewhere, Will, like not a few conservatives, drifts into intellectual quicksand in trying to reconcile his worship of the past with his admiration for the free market. What Daniel Bell called the cultural contradictions of capitalism poses something of a problem for him since, you might say, he admires libertarian economics but not the libertinism that accompanies it. And for all his denunciations of hedonism, Will’s contempt for environmentalists and admiration of capitalism prompts him to pour scorn on measures to protect the planet. Suddenly, the swollen appetites of Americans are O.K. According to Will, in a column from 2002, “Beware the wrath of Americans who like to drive, and autoworkers who like to make, cars that are large, heavy and safer than the gasoline sippers that environmentalists prefer.”

I guess I wasn't the only one to notice.  But at a certain point, does one wonder whether such lazy and deceptive thinking deserves to be bound in a volume and reprinted?

Today Paul Krugman writes:

Thus, when mad cow disease was detected in the U.S. in 2003, the Department of Agriculture was headed by Ann M. Veneman, a former food-industry lobbyist. And the department’s response to the crisis — which amounted to consistently downplaying the threat and rejecting calls for more extensive testing — seemed driven by the industry’s agenda.

One amazing decision came in 2004, when a Kansas producer asked for permission to test its own cows, so that it could resume exports to Japan. You might have expected the Bush administration to applaud this example of self-regulation. But permission was denied, because other beef producers feared consumer demands that they follow suit.

When push comes to shove, it seems, the imperatives of crony capitalism trump professed faith in free markets.

This would show at best that the people (like Bush or Veneman) who profess belief in free markets don't have it.  It wouldn't however show that free markets are a failure at such regulation (which is what Krugman intends to show).  In fact, it seems to me, it would make the point that regulation of the free market produces problems such as the one Krugman describes.   

 

Academics, Straw Man

Twaddle

Courtesy of Brian Leiter.  Here's noted historian of ancient philosophy (and much else) Jonathan Barnes on Contintental Philosophy:

[M]ost philosophers who belong to the so-called analytical tradition are pretty poor philosophers. (Most academics who do anything are pretty poor at doing it; and philosophy, or so it seems to me, is a subject in which it is peculiarly difficult to do decent stuff. A modestly competent historian may produce a modestly good history book; a modestly competent philosopher has no reason to publish his modest thoughts.)   But there's a big difference between the analyticals and the continentals: what distinguishes the continental tradition is that all its members are pretty hopeless at philosophy. Myself, I've read scarcely a hundred continental pages. I can't see how any rational being could bear to read more; and the only question which the continental tradition raises is sociological or psychological: How are so many apparently intelligent young people charmed into taking the twaddle seriously?

Why bother indeed with straw men, they take so much time to construct, just to knock down in the end.

Ad hominem arguments

Here's a link to an article in Scientfic American mind about various kinds of ad hominem arguments.  Yvonne Raley, the author, writes:

Although ad hominem arguments have long been considered errors in reasoning, a recent analysis suggests that this is not always the case. In his new book, Media Argumentation: Dialectic, Persuasion, and Rhetoric, University of Winnipeg philosopher Douglas Walton proposes that fallacies such as the ad hominem are better understood as perversions or corruptions of perfectly good arguments. Regarding the ad hominem, Walton contends that although such attacks are usually fallacious, they can be legitimate when a character critique is directly or indirect­ly related to the point being articulated.

If Walton is right, distinguishing clearly between these cases is important to evaluating the validity of statements people make to us about others. Good or fair uses of ad hominem critiques should, in fact, persuade us, whereas unwarranted uses should not.

I'd say indeed.  But this seems to me somewhat obvious–and the distinction between good and bad character attacks–a central feature of any notion of a fallacy.  All fallacies, I'd argue at least, seem like good pieces of reasoning–and have, as a result, close non-fallacious cousins.  Some analogies are good, some are bad.  The ones that are particularly bad we might call "weak analogies of the fallacious variety."  Some personal attacks are obviously legitimate–when character is an issue (as it often is).  Some are not.  The ones that aren't we might call "ad hominem."  The others we might call something else.

Racial interpretations

Kathleen Parker–yes, the one of blut und boden–wonders:

Can we critique the issues—and the man—without resorting to racial interpretations and recriminations? If McCain wins, can his victory simply be a loss for Democrats—and not a loss specifically for African-Americans?

The answers to those questions will be the measure of whether we have really progressed to the point we claim.

This is not directed at herself of course.  For the other day she wondered whether Obama had enough generational equity to be truly American.  His family had not poured enough into the soil.  She wrote:

It's about blood equity, heritage and commitment to hard-won American values. And roots.

Some run deeper than others and therein lies the truth of Fry's political sense. In a country that is rapidly changing demographically—and where new neighbors may have arrived last year, not last century—there is a very real sense that once-upon-a-time America is getting lost in the dash to diversity.

We love to boast that we are a nation of immigrants. But there's a different sense of America among those who trace their bloodlines back through generations of sacrifice.

Contributing to the growing unease among yesterday's Americans is the failure of the federal government to deal with illegal Immigration. It isn't necessarily racist or nativist to worry about what these new demographics mean to the larger American story. 

I can't really see the "issue" in that.

This is because this remark is directed at Democrats.  Can, in other words, Kathleen Parker and her friends say racist things without fear of being called racists. 

This, she thinks, is progress.

The President of the Czech Republic has helped Charles Krauthammer find the true enemy of freedom.  It's knowledge about the natural world.  This knowledge is especially dangerous if Krauthammer doesn't have the patience, time, or expertise to understand it.  He writes:

Predictions of catastrophe depend on models. Models depend on assumptions about complex planetary systems — from ocean currents to cloud formation — that no one fully understands. Which is why the models are inherently flawed and forever changing. The doomsday scenarios posit a cascade of events, each with a certain probability. The multiple improbability of their simultaneous occurrence renders all such predictions entirely speculative.

Yet on the basis of this speculation, environmental activists, attended by compliant scientists and opportunistic politicians, are advocating radical economic and social regulation. "The largest threat to freedom, democracy, the market economy and prosperity," warns Czech President Vaclav Klaus, "is no longer socialism. It is, instead, the ambitious, arrogant, unscrupulous ideology of environmentalism."

If you doubt the arrogance, you haven't seen that Newsweek cover story that declared the global warming debate over. Consider: If Newton's laws of motion could, after 200 years of unfailing experimental and experiential confirmation, be overthrown, it requires religious fervor to believe that global warming — infinitely more untested, complex and speculative — is a closed issue.

But declaring it closed has its rewards. It not only dismisses skeptics as the running dogs of reaction, i.e., of Exxon, Cheney and now Klaus. By fiat, it also hugely re-empowers the intellectual left.

For a century, an ambitious, arrogant, unscrupulous knowledge class — social planners, scientists, intellectuals, experts and their left-wing political allies — arrogated to themselves the right to rule either in the name of the oppressed working class (communism) or, in its more benign form, by virtue of their superior expertise in achieving the highest social progress by means of state planning (socialism).

Two decades ago, however, socialism and communism died rudely, then were buried forever by the empirical demonstration of the superiority of market capitalism everywhere from Thatcher's England to Deng's China, where just the partial abolition of socialism lifted more people out of poverty more rapidly than ever in human history.

Just as the ash heap of history beckoned, the intellectual left was handed the ultimate salvation: environmentalism. Now the experts will regulate your life not in the name of the proletariat or Fabian socialism but — even better — in the name of Earth itself.

Such a combination of straw men (the weakest versions of global warming arguments–not to Newsweeks's idea of "debate" about global warming), red herrings (communism, socialism, etc.), ad hominem (arrogant scientists are just trying to rule the world), ad ignorantiam (since we don't know much about the effects of carbon, let's do nothing. . . ), and just plain non sequiturs (Newton's law of motion was "overthrown" so distrust everything short of that) has not been seen for, um, weeks on this page.

We can’t have nice things

Scott McClellan, former White House Press Secretary, has written a book which by all accounts is quite critical of his former boss's handling of the Iraq war, among other things.  Does McClellan have interesting things to say?  Most certainly.  He worked there, after all.  Is he right?  Maybe.  But you can bet on one thing, we're not going to get a lot of enlightened discussion of this from those who run our nation's public discourse.  Here, for instance, is Fox News' Gretchen Carlson:

CARLSON: Scott McClellan better not have any skeletons in his closet. I hope he didn’t do anything that he doesn’t want the world to know about because we all have, and all of his secrets are going to be coming out.

We've already heard a litany of "he's-only-saying-that-because-of-x-y-or-z" remarks.  This one is different in its completely irrelevant reference to things "we all have" in our past.  As my parents used to say, this is why we can't have nice things.

A reader (hurray for readers) wondered if I might have something to say about this column on same-sex marriage.  I might.  I'd say the author hasn't even really tried.  Luckily, however, he italicizes his points so even I can see where to look.  His points are three in number.  And three is the number of his points, not four, not two.  He writes:

It is not the business of judges to make public policy.

Reasonable men and women can disagree on whether same-sex unions should be granted legal recognition, or whether such recognition should rise to the level of marriage. The place to work out those disagreements is the democratic arena, not the courtroom.

Well, the court, which decides matters such as these, is an institution in our democracy–a fundamental one, some might not implausibly suggest.  Its decisions necessarily have to do with public policy.  This argument–judicial activism!–really ought to be retired: they're little question-begging argumentative stand-ins.  Make a legal argument against the legal argument.  

Point number two:

The radical transformation of marriage won't end with same-sex weddings.

Another well-worn anti gay marriage argument.  Where will it end?  Well, the slope begins with actual marriage, so one can only conclude that the existence of marriage between a "straight" couple will lead to all sorts of weird marriages.  Besides, the problem with this particular variation of the slippery slope argument, it tacitly admits there's nothing wrong with gay marriage–the problem is rather with all of the other crazy marriages that will follow in its wake.  Of course, if there's a problem with those marriages, you can just make arguments against them for what they are (marriage between three), rather than something else they're not (marriage between two consenting adults).

Point number three:

Society has a vested interest in promoting only traditional marriage.

Which is the argument of the gay marriage advocates–they want a traditional marriage too–its legitimacy and legal benefits.  Like the one Britney had–the first one or the second, take your pick.  What's really silly about this claim is that it supposes gay marriage would be some kind of competitor or threat for "traditional" marriage.  This doesn't seem to be the case at all.  If history is any guide, gay couples have existed (with diminished or nonexistent legal status of course) for a very long time.  Their existence hasn't done much to undermine traditional marriage.  Not as much as, say, divorce, infidelity, sports, weight loss or gain, age, youth, or failure to put the toilet seat down.

The only thing that makes George Will madder (and more incoherent) than "global warming" are teachers' unions.  Just as teachers' unions have singularly (without any interference from any other causal factor) been able to destroy public education and all that's good in America, environmentalists aim to destroy the economy for their Marxist political agenda.  I wish I were kidding:

What Friedrich Hayek called the "fatal conceit" — the idea that government can know the future's possibilities and can and should control the future's unfolding — is the left's agenda. The left exists to enlarge the state's supervision of life, narrowing individual choices in the name of collective goods. Hence the left's hostility to markets. And to automobiles — people going wherever they want whenever they want.

Today's "green left" is the old "red left" revised. Marx, a short-term pessimist but a long-term optimist, prophesied deepening class conflict but thought that history's violent dialectic would culminate in a revolution that would usher in material abundance and such spontaneous cooperation that the state would wither away.

The green left preaches pessimism: Ineluctable scarcities (of energy, food, animal habitat, humans' living space) will require a perpetual regime of comprehensive rationing. The green left understands that the direct route to government control of almost everything is to stigmatize, as a planetary menace, something involved in almost everything — carbon.

He gets to this astoundingly moronic conclusion (that global warming is a myth perpetrated by "the left") by two main arguments.  First, he uncritically accepts of the word of a poorly qualified climate change deniers and climate change danger skeptics.  This time it's not Michael Crichton, science fiction author, but Nigel Lawson (that's Nigella's father), former British Cabinet member.  I can't determine what his specific expertise is here.  But it's obvious that he doesn't deny the fact of global warming–something which Will seems to do here.  He merely denies that it's a bad thing.  He writes (Will's quote):

"Over the past two-and-a-half-million years, a period during which the planet's climate fluctuated substantially, remarkably few of the earth's millions of plant and animal species became extinct. This applies not least, incidentally, to polar bears, which have been around for millennia, during which there is ample evidence that polar temperatures have varied considerably."

According to him at least, the climate is changing.  To be fair, of course, he'll probably deny that the cause is the presence of unabsorbed carbon in the atmosphere.  But that's a different claim from the one he's making above.  Scientists would agree of course that the earth's temperature has changed considerably over the years.  But not so drastically.  And not, at least not recently, because of carbon in the atmosphere. 

Will's second argument is inconsistent with this first one.  He writes

Want to build a power plant in Arizona? A building in Florida? Do you want to drive an SUV? Or leave your cellphone charger plugged in overnight? Some judge might construe federal policy as proscribing these activities. Kempthorne says such uses of the act, unintended by those who wrote it in 1973, would be "wholly inappropriate." But in 1973, climate Cassandras were saying that "the world's climatologists are agreed" that we must "prepare for the next ice age" (Science Digest, February 1973).

This one holds that the climate is probably not changing, or that climatologists should not be believed, because in the 70s there was concern (in the popular media) about "a new ice age."  In other words, Will suggests there is some kind of inconsistency in the arguments of current climatologists because an article or two (and he always cites specific articles on this point–good for him!) claimed the opposite of what they now claim.  This, of course, hardly makes them inconsistent.  Besides, reports from the 70s popular media ought not be held up against the work of actual scientists.  You might hold it up against the current disaster-media complex, but that would be something else entirely.

In one final bit of craziness, he concludes the above paragraph with the following warning:

And no authors of the Constitution or the 14th Amendment intended to create a "fundamental" right to abortion, but there it is.

Lest you think we won't slide down the slippery slope to less autonomy of personal choices, just look at what happened with Roe v. Wade.
