Slashdot linked to this article by the President of the Czech Republic (corrected 6-16). It’s a treat for the connoisseur of bad argument. First a nice straw man argument.

We are living in strange times. One exceptionally warm winter is enough – irrespective of the fact that in the course of the 20th century the global temperature increased only by 0.6 per cent – for the environmentalists and their followers to suggest radical measures to do something about the weather, and to do it right now.

Not sure what to make of this paragraph. The last sentence seems to hang on a sort of ambiguity–in one sense environmentalists want a sort of “central planning.” But not, it seems, to me in the same sense as communism. Whatever it is, it’s a pretty cheap trick, I think.

As someone who lived under communism for most of his life, I feel obliged to say that I see the biggest threat to freedom, democracy, the market economy and prosperity now in ambitious environmentalism, not in communism. This ideology wants to replace the free and spontaneous evolution of mankind by a sort of central (now global) planning.

This paragraph is interesting.

The environmentalists ask for immediate political action because they do not believe in the long-term positive impact of economic growth and ignore both the technological progress that future generations will undoubtedly enjoy, and the proven fact that the higher the wealth of society, the higher is the quality of the environment. They are Malthusian pessimists.

Not sure I see the relevance of the “proven fact,” which, nonetheless, seems plausible to me as a simple generalization, for the problem of global warming. Does this imply that we can simply assume that global warming is not a threat, if it is caused by higher standard of living?

How about this? Perhaps an ignoratio elenchi?

The scientists should help us and take into consideration the political effects of their scientific opinions. They have an obligation to declare their political and value assumptions and how much they have affected their selection and interpretation of scientific evidence.

Should scientists qua scientists really take into consideration the political effects of their scientific opinions (qua scientific opinions)? Even if that’s so, the last sentence is just nutty. But since it has no obvious logical connection to the first sentence (does it follow from the previous one? explain? is it a case of “loosely connected statements?”), we have either, if we take it as an argument, a sort of ignoratio elenchi or red herring, perhaps.

He closes with a series of suggestions that. . .well, my description can’t do them justice. (My favorites are 4 and 5).

  • Small climate changes do not demand far-reaching restrictive measures
  • Any suppression of freedom and democracy should be avoidedc
  • Instead of organising people from above, let us allow everyone to live as he wants
  • Let us resist the politicisation of science and oppose the term “scientific consensus”, which is always achieved only by a loud minority, never by a silent majority
  • Instead of speaking about “the environment”, let us be attentive to it in our personal behaviour
  • Let us be humble but confident in the spontaneous evolution of human society. Let us trust its rationality and not try to slow it down or divert it in any direction
  • Let us not scare ourselves with catastrophic forecasts, or use them to defend and promote irrational interventions
    in human lives.

Let’s get cynical

V.D.Hanson sees right through your pro-immigration stance, university perseffers:

>Most cynical of all, however, are the moralistic pundits, academics and journalists who deplore the “nativism” of Americans they consider to be less-educated yokels. Yet their own jobs of writing, commenting, reporting and teaching are rarely threatened by cheaper illegal workers.

>Few of these well-paid and highly educated people live in communities altered by huge influxes of illegal aliens. In general, such elites don’t use emergency rooms in the inner cities and rural counties overcrowded by illegal aliens. They don’t drive on country roads frequented by those without licenses, registration and insurance. And their children don’t struggle with school curricula altered to the needs of students who speak only Spanish.

Teaching. Cynical.

But perhaps Hanson is on to something, not eve the jobs of the California Republican Party are safe from foreigners.

From Editor and Publisher:

>SECRETARY RICE: Look, let me tell you what I think about Scooter Libby. I think he’s served the country really well. I think he did it to the best of his ability. I think that he is going through an extremely difficult time with his family and for him. And you know, I’m just desperately sorry that it’s happening to him and I — you know, the legal system has spoken, but I tell you, this is a really good guy who is a good public servant and ought to be treated in accordance with that.

I wonder if such feelings of pity are proper for fallen soldiers.

Contradictions, David Brooks, False Dichotomy

Today David Brooks tries to erase any subtlety from the immigration question. The real conflict is between educated globe-trotting elites and local Nascar types. In case you thought that’s the usual silly dichotomy, you’d be right. This time, however, he finds a way to contradict himself and patronize both groups of the dichotomy.

>The conventional view is that an angry band of conservative activists driven by nativism and economic insecurity is killing immigration reform. But this view is wrong in almost every respect.

Three paragraphs of general assertions lead to the following conclusion:

>What’s shaping the immigration debate is something altogether deeper and more interesting. And if you want to understand what it is, start with education. Between 1960 and 1980, the share of Americans enrolled in higher education exploded. The U.S. became the first nation in history with a mass educated class. The members of this class differed from each other in a thousand ways, but they tended to share a cosmopolitan approach to the world. They celebrated cultural diversity and saw ethnocentrism as a sign of backwardness.

No attempt is made to support that claim with any research. Broad, unsupported generalizations–even in the context of a 750 word column–don’t deserve anyone’s serious consideration. If you can’t even point to the right kind of source for that evidence, you probably shouldn’t write it in a newspaper.

Here’s the dichotomy. First, the smart, elite types:

>Liberal members of the educated class celebrated the cultural individualism of the 1960s. Conservative members celebrated the economic individualism of the 1980s. But they all celebrated individualism. They all valued diversity and embraced a sense of national identity that rested on openness and global integration.

Now the yokels:

>This cultural offensive created a silent backlash among people who were not so enamored of rampant individualism, and who were worried that all this diversity would destroy the ancient ties of community and social solidarity. Members of this class came to feel that America’s identity and culture were under threat from people who didn’t understand what made America united and distinct.

But they’re not driven by nativism–they only feel that the ancient ties of solidarity and community of their native culture is under threat from outsiders.

George Will, Post hoc ergo propter, Straw Man

Post tax cuts ergo propter tax cuts

66 Comments

It has become tiresome again to point out the numbskullery of George Will’s arguments. As he often does, today he misrepresents the positions of Bush’s tax cut objectors and asserts that the tax cuts in precisely the way Bush (and Reagan, of course) envision them have made the economy grow.

The first:

>Last Sunday, eight Democratic presidential candidates debated for two hours, saying about the economy . . . next to nothing. You must slog to Page 43 in the 51-page transcript before Barack Obama laments that “the burdens and benefits of this new global economy are not being spread evenly across the board” and promises to “institute some fairness in the system.”

>Well. When in the long human story have economic burdens and benefits been “spread evenly”? Does Obama think they should be, even though talents never are? What relationship of “fairness” does he envision between the value received by individuals and the value added by them? Does he disagree — if so, on what evidence? — with Federal Reserve Chairman Ben Bernanke that “the influence of globalization on inequality has been moderate and almost surely less important than the effects of skill-biased technological change”?

Someone with madder internet skillz than me ought to do a Nexis search for how many times Will writes “Well period” after quoting someone ought of context. I suppose Obama has only those sound bites to offer–no explanation behind them or anything. Just for the record, the complaint about the tax cuts consisted in their uneven distribution. Critics argued that they would have been more effective had people who could spend the money gotten more, and people who don’t spend or don’t need gotten less. That’s the argument–I’m not having it now, so don’t comment on it–so Will ought to deal with that claim. Instead he makes it sound like the Democrats were against any tax cuts or endorsed only the most Robin Hood of tax schemes. Aside from that, he makes it sound like the avoided the topic of the economy at the debate. Well. At the debate, they’re not the ones asking the questions. Besides, the one who did most of the talking was Wolf Blitzer.

The second:

>In the 102 quarters since Ronald Reagan’s tax cuts went into effect more than 25 years ago, there have been 96 quarters of growth. Since the Bush tax cuts and the current expansion began, the economy’s growth has averaged 3 percent per quarter, and more than 8 million jobs have been created. The deficit as a percentage of gross domestic product is below the post-World War II average.

Post tax cuts ergo propter tax cuts.

George Will, Hasty Generalization

Refutation

6 Comments

So you want to refute–i.e., prove to be false–someone else’s generalization. There’s only one way that I can think of: show that the generalization is false. That means your evidence of its falsity must be as general as the claim itself. Pointing out exceptions to a generalization only demonstrates your inability to grasp one foundational notion of informal reasoning. Two examples of this from our dear friend, George F. Will:

>Once America’s most industrialized city, Newark attracted the attentions of New York mobsters (the movie “On the Waterfront” was filmed on New Jersey docks) whose depredations contributed to the flight of industry just as blacks were arriving from the South. Partly because of the cost that organized crime added to many city contracts, Newark spent twice as much per citizen as did other midsize cities. And the riots came, (redundant) evidence of the problematic nature of attempts to spend one’s way to domestic tranquility.

The first part of this paragraph shows how the spending in Newark was uniquely corrupt. How that then can be evidence for the claim that spending does not equal domestic tranquility baffles: it wasn’t effective spending. Unless, of course, Mr.Will means to refute the view of the person who says: “all social spending–including the corrupt cosa nostra kind–ensures tranquility–and if you find one counterexample, I will be wrong.”

Here’s the second:

>Today, per-pupil spending tops $17,000, which is 75 percent above the national average and a (redundant) refutation of the public education lobby’s not disinterested judgment that in primary and secondary education, cognitive outputs correlate with financial inputs. Seventy percent of Newark’s 11th-graders flunk the state’s math test. Booker says that under the previous mayor’s administration, every elected official sent his or her children to private schools.

Again. That’s hardly a “refutation” of that rule. It’s a counter-example. And perhaps a reminder that not just any money counts. Money well spent counts. I think that’s probably what the rule means.

But in both cases, in order to show the falsity of the generalization being refuted, Mr.Will will have to come up with a more representative counter-example than the city awash in mob corruption (on account, in part, because of its place in global trade–the port of Newark). If he wants actually to say something true, then perhaps he ought to try to do a little non-Heritage foundation research.

Appeal to Pity, William Kristol

Sweet misericordia

According to Bill Kristol, you’re not a criminal if you “seek to do what is right for the country” or “work closely” with the President.

>Will Bush pardon Libby? Apparently not–even if it means a man who worked closely with him and sought tirelessly to do what was right for the country goes to prison. Bush spokeswoman Dana Perino, noting that the appeals process was underway, said, “Given that and in keeping with what we have said in the past, the president has not intervened so far in any other criminal matter and he is going to decline to do so now.”

>So much for loyalty, or decency, or courage. For President Bush, loyalty is apparently a one-way street; decency is something he’s for as long as he doesn’t have to take any
risks in its behalf; and courage–well, that’s nowhere to be seen. Many of us used to respect President Bush. Can one respect him still?

And after all that Bush has done and failed to do, this is the reason Bill Kristol loses respect for him.

False Dichotomy, George Will, Straw Man

Liberalism is dumb

2 Comments

Yesterday, George Will made his case for “conservatism.” This mainly involves making the case against Mayor Quimby, the corrupt and degenerate mayor of the fictional town of Springfield on the Simpsons. For in making the case for conservatism, Will presumes there is only one alternative–his. There may indeed be two major parties, but hardly anyone at this point can claim that they divide along the lines Will suggests–one is for freedom, the other for equality. The one that ought to be for freedom–the conservative one–openly advocates the rollback of plain-language constitutional guarantees; while the one that’s for equality over freedom, often comes out for freedom over equality. If we had more patience with this, we’d say what Will means is the freedom of individuals (which includes corporations, but not unions of workers) to make money without government restraint; but not the freedom of individuals to seek redress through the courts. Someone else can make that case. We’d just like to point out the silly straw man, and consequent false dichotomy. Someone really ought to make the case for “conservatism” in a way that does not presuppose some dumb-ass liberal view. Liberalism after all has its John Rawls.

Here’s the straw man:

>Liberals tend, however, to infer unequal opportunities from the fact of unequal outcomes. Hence liberalism’s goal of achieving greater equality of condition leads to a larger scope for interventionist government to circumscribe the market’s role in allocating wealth and opportunity. Liberalism increasingly seeks to deliver equality in the form of equal dependence of more and more people for more and more things on government.

>Hence liberals’ hostility to school choice programs that challenge public education’s semimonopoly. Hence hostility to private accounts funded by a portion of each individual’s Social Security taxes. Hence their fear of health savings accounts (individuals who buy high-deductible health insurance become eligible for tax-preferred savings accounts from which they pay their routine medical expenses — just as car owners do not buy insurance to cover oil changes). Hence liberals’ advocacy of government responsibility for — and, inevitably, rationing of — health care, which is 16 percent of the economy and rising.

>Steadily enlarging dependence on government accords with liberalism’s ethic of common provision, and with the liberal party’s interest in pleasing its most powerful faction — public employees and their unions. Conservatism’s rejoinder should be that the argument about whether there ought to be a welfare state is over. Today’s proper debate is about the modalities by which entitlements are delivered. Modalities matter, because some encourage and others discourage attributes and attitudes — a future orientation, self-reliance, individual responsibility for healthy living — that are essential for dignified living in an economically vibrant society that a welfare state, ravenous for revenue in an aging society, requires.

Right. Now the false dichotomy:

>This reasoning is congruent with conservatism’s argument that excessively benevolent government is not a benefactor, and that capitalism does not merely make people better off, it makes them better. Liberalism once argued that large corporate entities of industrial capitalism degraded individuals by breeding dependence, passivity and servility. Conservatism challenges liberalism’s blindness about the comparable dangers from the biggest social entity, government.

Liberals pro-government. Government bad. Conservatives anti-government. Anti-government good. Conservatism good.

Brooks on Gore III

Lots to choose from today: Sam Brownback’s evolution confusion or George Will’s “Case for Conservatism” (which is, as one would suspect, the case against his cartoonish liberal with the subsequently unjustified claim that this makes the case for his view–which it doesn’t). But David Brooks’ column the other day still offers some final ignorant tidbits. So far, the reader may remember, Brooks has accused Gore of favoring some kind of vulcan-like existence because he wants people to argue with facts and logic.

The final paragraphs of Brooks piece descend into nonsense. He writes:

> This, in turn, grows out of a bizarre view of human nature. Gore seems to have come up with a theory that the upper, logical mind sits on top of, and should master, the primitive and more emotional mind below. He thinks this can be done through a technical process that minimizes information flow to the lower brain and maximizes information flow to the higher brain.

Now the mind is identical to the brain? Doesn’t that make Brooks a determinist?

>The reality, of course, is that there is no neat distinction between the “higher” and “lower” parts of the brain. There are no neat distinctions between the “rational” mind and the “visceral” body. The mind is a much more complex network of feedback loops than accounted for in Gore’s simplistic pseudoscience.

>Without emotions like fear, the “logical” mind can’t reach conclusions. On the other hand, many of the most vicious, genocidal acts are committed by people who are emotionally numb, not passionately out of control.

Now we’ve veered far from the discussion of civil discourse, into simplistic (ironically it seems) pseudo-science about the nature of reasoning and consciousness and their relation to brain processes.

>Some great philosopher should write a book about people — and there are many of them — who flee from discussions of substance and try to turn them into discussions of process. Utterly at a loss when asked to talk about virtue and justice, they try to shift attention to technology and methods of communication. They imagine that by altering machines they can alter the fundamentals of behavior, or at least avoid the dark thickets of human nature.

>If a philosopher did write such a book, it would help us understand Al Gore, and it would, as he would say, in fact, evoke a meaningful response.

I don’t think any philosopher would write a book of that sort, as it rests on a confusion between argument and explanation. Brooks can’t bring himself to consider Al Gore’s argument, so he distorts it, and then asks what would explain such a distorted view. Ironically, even Gore’s distorted view is superior, on Brooks’ own grounds, to Brooks’ brain state analysis of human nature.

Perhaps Gore can include Brooks unreasoning response as an appendix in a subsequent edition of his book about the assault on rational discourse.

David Brooks, False Dichotomy, Straw Man

Brooks on Gore II

David Brooks’ review of Al Gore’s latest book merits another post (at least). Gore argues that the participatory nature of our democracy has been undermined by the one-way media. While that may not be an original idea, Gore has a lot of experience with its consequences. Brooks has no patience, however, for argument (something we have long suspected). He writes:

>But Gore’s imperviousness to reality is not the most striking feature of the book. It’s the chilliness and sterility of his worldview. Gore is laying out a comprehensive theory of social development, but it allows almost no role for family, friendship, neighborhood or just face-to-face contact. He sees society the way you might see it from a speaking podium — as a public mass exercise with little allowance for intimacy or private life. He envisions a sort of Vulcan Utopia, in which dispassionate individuals exchange facts and arrive at logical conclusions.

It really would suck if people “exchang[ed] facts and arriv[ed] at logical conclusions.” The mysterious thing here is that not only is Gore lamenting the absence of civil discourse–which is, dear Mr.Brooks, a kind of civic engagement–but he can hardly be taken to be claiming that it’s the only thing people do.

What lurks behind Brooks dimwitted review is the classic Brooksian dichotomy: things can only be one way (my way) or the totally absurd other way (whatever your way is). Gore cannot be right about logic, because then we would all be Vulcans–like Dr.Spock (the one on TV). Maybe Al Gore is saying that we need logic at least, or perhaps, also.

Some, maybe like Kant or Aristotle or Aquinas, would agree with Gore.

More on this tomorrow. It’s too horrible for one or two days.
