How Thoughtful

The funny thing about op-ed writers is that oftentimes they don’t seem to make any arguments at all, eschewing words such as “therefore” or “hence” or perhaps even “ergo” which let the reader know that he or she has just brought an argument to its conclusion. There’s certainly nothing wrong with this practice per se. After all, why bore the reader with the tedium of logical place-holders when a good writer can make an argument without them?

The problem with this strategy is that sometimes one cannot be quite certain what the actual argument is. Such is the case with David Brooks’ piece in today’s New York Times.

As best as we have been able to establish, Brooks attempts to show the reader that not all Republicans are right wing nut jobs by “introducing” us to a fundamentalist Christian legislator from Indiana who simultaneously denies the theory of Evolution and thinks that Clinton should not have been impeached. Nothing strange about that. Or is there?

Let’s take a closer look at how Brooks begins his argument:

One of the most thoughtful politicians in Washington doesn’t believe in the theory of evolution. I thought I’d introduce him to you because over the next week we’re going to hear a lot of stereotypes about Republicans and especially social conservatives. It might be useful to interrupt those prejudices with the more complicated reality.

Unless Brooks is attempting to demonstrate a fact obvious to anyone who paid attention to primary elections that were recently held around the country (where even Republicans disagreed with Republicans–Imagine that!), then he is setting up a kind of fallacious argument in reverse. This is to say that he is alleging that his opponent (where there are arguments, there are always opponents, real or imaginary) thinks that Republicans can all be painted with one brush as, note the choice of words, not “thoughtful”. He then proceeds, with a long series of anecdotes from the life and career of the conservative Republican in question, to demonstrate that this particular Republican doesn’t always take typical positions. By making this argument Brooks alleges–indirectly, mind you–that his opponent (that is, the author of the stereotypes, here unnamed) is the one who commits the fallacy of hastily generalizing. This implicit accusation of intellectual irresponsibility, is itself intellectually irresponsible. It implicity claims that his opponent does not have reasons or arguments against the views (nuanced though they may be) of his Republican poster child. While some–nay perhaps many–may believe that no one who fails to embrace the theory of evolution can possibly be “thoughtful” in any meaningful sense of the term, many others indeed have reasons to oppose some or all of his arguments. By claiming that his views are thoughtful and accusing the opposition of stereotyping, Brooks stereotypes his opposition’s argument as absurdly weak, a straw man, in other words.

Now it may be objected that Brooks isn’t making any argument at all here. Well, if he’s not, then what is this doing on the op-ed page? But if in fact Brooks’ argument is directed at those who actually do hold such caricatured views, then we have grossly overestimated the intellectual heft of the average reader of the New York Times.

Ad hominem in Reverse!

Today’s Krauthammer presents us with an interesting example of what we might call a reverse ad hominem fallacy. But before that, a little straightforward ad hominem, just to get going:

Actually, this time around, even more apoplectic. The Democrats’ current disdain for George Bush reminds me of another chess master, Efim Bogoljubov, who once said, “When I am White, I win because I am White” — White moves first and therefore has a distinct advantage — “when I am Black, I win because I am Bogoljubov.” John Kerry is a man of similar vanity — intellectual and moral — and that spirit thoroughly permeates the Democratic Party.

So the basic strategy is to heap up abuse on the Democratic candidate. Nothing new or interesting about that. We all know that Kerry has arguments for his positions and that these arguments should be examined on their merits. The same naturally is the case for the Republican candidate, George W. Bush. But herein lies Krauthammer’s trick. Ignoring the arguments of the Republican candidate, Krauthammer instead accuses the “liberals as a body” of engaging in vicious and groundless attacks on Bush himself:

The loathing goes far beyond the politicians. Liberals as a body have gone quite around the twist. I count one all-star rock tour, three movies, four current theatrical productions and five bestsellers (a full one-third of the New York Times list) variously devoted to ridiculing, denigrating, attacking and devaluing this president, this presidency and all who might, God knows why, support it.

So what we have is the claim that the opposition’s arguments are nothing but vicious ad hominem personal attacks and as such not worth pondering even for a moment. Now to some extent–sometimes to a great extent indeed–these sorts of attacks do take place. But in the sources alluded to here–and indeed in any serious discussion of the current election–arguments are put forward, evidence is offered, and conclusions drawn (justifiably or not). The arguments, like all arguments, deserve in civil political society to be examined on their merits. Broadly generalizing–generalizing hastily–that all such attacks are ad hominem is to make their arguments seem weaker than they might (“might” becuase no attempt is made to address their claims) actually be. As far as rhetorical dirty tricks goes, this is not only one of the dirtiest, but also one of the cleverest. You accuse the opposition of a being intellectually irreponsible, and so force him or her on the defensive. This may play well on a cable TV shoutfest, but its printed form only too quickly shows it to be absolute nonsense.

Equal opportunity

Guest Columnist for the New York Times Dahlia Lithwick makes the following argument about Abu Ghraib and the November election:

You can choose to connect these dots, or cast your vote in November based on whether Colonel Mustard was in a Swift boat with a lead pipe. But Abu Ghraib can’t be blamed solely on bad apples anymore. It was the direct consequence of an administration ready to bargain away the rule of law. That started with the suspension of basic prisoner protections, because this was a “new kind of war.” It led to the creation of a legal sinkhole on Guantánamo Bay. And it reached its zenith when high officials opined that torture isn’t torture unless there’s some attendant organ failure.

There are two textbook non sequiturs here. The first, a classic false dichotomy, erroneously claims that there are two alternatives–assign blame for Abu Ghraib all the way up the chain to the Whitehouse, or believe the now completely discredited Swift Boat story on Kerry. One can, however, not believe the Swift Boat story and not connect the dots all the way to the Whitehouse, or connect the dots all the way to the Whitehouse and believe the Swift Boat story. The two altenatives, in other words, are by no means mutually exclusive.

The second non sequitur, the post hoc ergo propter hoc (after this therefore because of this) fallacy, claims that the horrendous torture of Abu Ghraib is a direct consequence of the policies the current administration and its equivocal statements on the laws regarding detainees in what it describes as the “war on terrorism.” No doubt the one event–the torture–follows the existence of the administration and its various policies. But whether these events are causally linked in the manner of a “direct consequence” is something that needs to be established on the evidence. The temporal precedence of the one is hardly sufficient.

Now this is not to say of course that it is not the case that the administration is directly responsible. It is just isn’t responsible on the argument Lithwick has offered.

False Cause, General discussion, Plain Bad Arguments

Bear Patrol

Here’s an oft-repeated howler printed in the New York Times from op-ed contributor and Marine Major on duty in Iraq Glen G. Butler

The pre-emptive doctrine of the current administration will continue to be debated long after I’m gone, but one fact stands for itself: America has not been hit with another catastrophic attack since 9/11. I firmly believe that our actions in Afghanistan and Iraq are major reasons that we’ve had it so good at home. Building a “fortress America” is not only impractical, it’s impossible. Prudent homeland security measures are vital, to be sure, but attacking the source of the threat remains essential.

How often have you heard this one in its various versions? The implication here is that the war on terrorism (including the invasion of Iraq) is the cause of there not being any terrorist attacks in the United States. Now the factual claims are no doubt true. First, we have invaded Afghanistan and Iraq, and there has not been another major terrorist attack-or any terrorist attack-in the United States. No attempt, however, on the part of the author, is made to demonstrate that the two major military operations are the cause of there not being any terrorist attacks in the United States (we should not forget the bombings in Bali and Madrid and elsewhere). Just because, in other words, the war on terrorism (including the invasion of Iraq which even according to George Bush had nothing to do with 9/11) has preceded the absence of catastrophic terrorist attacks in the United States since 9/11 does not mean it is the cause. What we have here, in more technical terms, is a perfect example of the post hoc ergo propter hoc fallacy-after this, therefore because of this, or the correlation-causation fallacy.

Should someone not be convinced by this analysis, consider the following scene from the Simpsons, where Homer remarks on the success of Springfield’s attempt to control bear activity:

Homer: “There’s not a single bear in sight–the ‘Bear Patrol’ is working like a charm”

Lisa: “That’s specious reasoning,”

H: “Thanks, honey,”

L: “According to your logic, this rock keeps tigers away”.

H: “Hmmm. How does it work?”

L: “It doesn’t.”

H: “How so?”

L: “It’s just a rock,”

H: “But I don’t see a tiger, anywhere.”

H: “Lisa, I want to buy your rock.”

And consider how many times this passage comes up in the context of the war on terrorism and similar matters. Should the author want to avoid the rock-tigers problem, and therefore avoid utter nonsense, he should offer evidence to the effect that specific terrorist attacks have actually been thwarted by the war on terrorism and the invasion of Iraq. Simply believing it firmly-and in the present author’s case, actually putting your life on the line for that belief-does not make it so. Undergoing much personal danger and sacrifice in the service of one’s belief does not make them true.
