A Missing the Point and Red Herring Sandwich

Cleaning out my drafts folder I came across this from a few months ago. I've always been baffled by those who argue against someone's concern for animal {suffering, lives, rights, etc.} by asking why they aren't concerned with some other form of injustice or suffering. Most of the time it isn't so wonderfully clear a case of missing the point.

Came across a nice case of "missing the point." In the aftermath of the release of an undercover video revealing animal abuse at an Ohio farm, Farm and Dairy editor Susan Crowall wrote a column in favor of the truth about the animal abuse, much of which raises skeptical questions about whether abuse was perhaps sponsored by the undercover agent, etc.. But, at the end of her column she shares the reflections of her husband on this incident.

There is no way to talk about the alleged incidents of animal abuse at the Ohio dairy farm without becoming emotional. When I went home from work last week and shared the emerging story to my husband, however, he found a way to put it in perspective in a new way.

Where are the undercover videos, where are all these well-funded activists, he asked, when it comes to children instead of animals?

. . ..

I’m not trying to downplay the incident. I watched the video once and I will not watch it again. Wanton animal abuse or neglect is inexcusable.

But I also agree with Keith. There are no multimillion dollar-backed undercover investigators, no news conferences, no outraged blog posts or online comments, no protests around homes, in 99% of the child abuse cases. There are just underpaid, overstressed social workers, and a society that cares too little, too late.

As nice a case of missing the point on Keith's part as you can find in a textbook. It may well be true that we should have more undercover investigators exposing child abuse, but, Keith is really just missing the point, and Crowall seems willing to use his non sequitur as part of her red herring strategy to change the subject in whatever way possible.

But, that's not all we find of logical interest in her column. Earlier, we find a nice attempt to impugn the motives of the organization that released the video:

“Animal agriculture is incapable of self-regulation,” condemns Mercy For Animals on its blog. MFA was the group behind the undercover footage and its packaging and release on the Web.

But readers need to be aware of the group’s ulterior motive, and that is promoting a vegan diet (vegans try to eliminate the use of animals for food, clothing or any other purposes). Nothing excuses the actions of the dairy farm employee, but you need to know where this group is coming from.

Not exactly an ad hominem, but certainly seems ad hominish.

And then we get a nice red herring rhetorical move in the form of a series of questions all of which are meant to suggest that there are big unanswered questions that might shed light on the incident.

Who was the undercover “investigator” from Mercy For Animals? When was he hired, if he was posing as an employee? Did he know Gregg before he arrived on the farm? When was Gregg hired? What is the farm’s process for checking references? Who were these guys’ references?

After these sorts of videos come out, it is now standard practice for the industry to attack the undercover investigator (or is that "investigator"?) for complicity in the animal abuse, and now, the industry and its lobbyists are attempting to make such investigations illegal, though several state legislatures have not passed the proposed legislature (Minnesota and Florida).

Funny fallacy fallacy

From Slate:

This is not even a straw man; it's some loose straw the writer is throwing in the air while yelling "Look at that man!"

Funny line, but it may be that it's not a straw man, because it's just not a straw man. Benjamin explained in the NYT that he is boycotting hetero-sexual weddings on the grounds that it is unreasonable for him to "financially and emotionally invest in a ritual that excludes [him] in all but five states."

The response to this, he says, is that his friends take him to task for foisting his political agenda on others. he seems to see their argument as:

P1. Your refusal to come to my wedding is foisting your political agenda on us.

P2. You should not foist your political agenda on us.

C. Therefore, you should not refuse to come to my wedding.

His response is that P1 is false. It is not just a political agenda, since his desire to be able to marry is a personal issue not a political one. He then accuses heterosexual supporters of gay-marriage of having a double-standard.

They’re proof of a double standard: Even well-meaning heterosexuals often describe their own nuptials in deeply personal terms, above and beyond politics, but tend to dismiss same-sex marriage as a political cause, and gay people’s desire to marry as political maneuvering.

Scocca asks "Who are these many straight people Benjamin claims to be describing?" The answer isn't hard to find in Benjamin's column:

Though Zach falls into that slim majority, he scolds me for being “peevish.” He says he resents me for blowing off his special day, for putting political beliefs ahead of our friendship and for punishing him for others’ deeds.

Their joy in their marriage is personal, and they take personal affront at Benjamin's refusal to take joy in their marriage. But, they think the objection to taking joy in an institution that forbids recognition of his own relationships is merely a political issue, and he replies that it is just as much a personal issue to be invited to celebrate an institution that he is excluded from.

Is this a straw man? Doesn't seem like it to me. But, neither is it a handful of straw thrown in the air. If someone accuses you of politicizing their wedding, it seems reasonable to deny that the issue is political rather than personal.

Is it a good argument? I'm not sure about that. I don't see that one guy is "proof of double standard." And, that might be where Scocca feels uneasy: Benjamin seems to draw some broader claims from his disagreement with his friend, and it's not clear that the broader claims are connected in the same way that the claims are connected in the disagreement. And second, in order to be a double-standard the judgment has to be about the same sort of case, and it isn't obvious what the more general case is.

Your wife or a snake?

Critics of anti-speciesist arguments, like presumably the Foundation for Biomedical Research in my previous post, often fall back onto simplified hypothetical moral situations in order, typically, to elicit an inconsistency in the opponent's belief sets or between their beliefs and actions. These arguments typically take the form of asking "your dog or your child?" On the basis of the inconsistency, there are a number of possible consequences that they might wish to suggest or draw, including:

a) Opponent's anti-speciesist view is false.

b) Opponent's anti-speciesist view is weakened.

c) Opponent is an unreliable judge of the moral issue due to the incoherence of their belief set.

d) Opponent is an unreliable judge of the moral issue due to hypocrisy.

As we've commented before, these Subjunctive Tu Quoque arguments are often fallacious, though sometimes they have some probative significance (e.g., by dialectically shifting the burden of argument). But, there is another case of argument that looks like the Subjunctive Tu Quoque, but operates differently.

P1: Opponent S asserts p, either generally or in situation A, on moral ground U.

P2: But, opponent S would assert ~p, in situation B.

C3: Opponent S should not hold p on moral ground U either generally or in situation A.

Here's an example from philosopher Carl Cohen.

"Tom Regan enjoys outdoor activities, and we can well imagine that on some cross-country hike a child of his may be bitten by one of the Eastern diamondback rattlesnakes abundant in those North Carolina woods, or a cottonmouth, or copperhead perhaps, or during a winter holiday in Martinique his wife may be struck by the fer-de-lance, a snake whose bite is often fatal if not swiftly treated with an antivenin. Happily, there is treatment readily available for such excruciatingly painful bites, an antivenin that is waiting for the Regan family or any family in need of it, at any good hospital in North Carolina or the Caribbean. But would Tom Regan's child be allowed to receive it? Here is the problem. The needed treatment for the bites of the family of pit vipers is Antivenin (crotalidae) Polyvalent-serum globulin obtained from the blood of healthy horses that have been injected with snake venoms to cause of the development, in their blood, of the needed antibodies. Those horses have been used without their consent, with some pain to them. But, if the antivenin is not administered quickly, children bitten by rattlesnakes (or other pit vipers) will suffer terribly, may lose an arm or leg, or even die." (Carl Cohen and Tom Regan, The Animal Rights Debate, Rowman and Littlefield, 2001. p 242.)

Here Carl Cohen is following out what he takes to be the consequence of Tom Regan's animal right's position. I don't think that he is actually arguing against Regan's view here, instead he is setting out the practical stakes of Regan's position before examining "with a very skeptical eye the philosophical arguments by which it is claimed that 'animal rights' are established" (p.243).

But, one might formulate an argument as follows:

P1: Tom Regan asserts that animals have rights not to be used for human purposes generally.

P2: But Tom Regan would/should assert that humans have the right to use animals (horses) in situation B.

C1: Tom Regan should not hold that animals have rights not to be used for human purposes generally.

or, C2: Tom Regan's judgment in P1 is unreliable.

This argument might have a similar structure as the standard reconstruction of the Socratic Elenkhos articulated by Gregory Vlastos, an instance of the Argument from Inconsistency. Though in the Elenkhos, we would add some additional premises to which the interlocutor agrees that entail C1, or for Socrates (on Vlastos' interpretation) the stronger claim that the original belief (animals have rights not to be used for human purposes generally) is false (Vlastos, Gregory "The Socratic Elenchos" Journal of Philosophy 79 (11), 1982, 711-714).

But, there is an important difference between arguments of this sort and the reconstructed implicit argument of FBR's billboard. In the case of Cohen's hypothetical, the hypothetical is an instance of the principle in question. In the case of FBR's billboard, the hypothetical is not. To put it simply:

Cohen: Using horses to produce anti-venom is a counter-example to the principle that animals have rights not to be used.

FBR: Saving a little girl rather than a rat is not an instance of the general category of using animals in research.

So, FBR cannot, I think, defend the implicit argument by modelling it on an implicit Elenctic argument. Conclusions about the use of animals in research is a non-sequitur from the assumed answer to the billboard's question.

Fallacies for Biomedical Research

The Foundation for Biomedical Research, an advocacy and lobbying organization for biomedical industries has been dumbing down the public discourse around the use of animals in medical research with bill-boards in several cities. ABCNews has the story http://abcnews.go.com/Health/Drugs/animal-research-billboards-pit-cute-girl-lab-rat/story?id=13371007

(ABCNEWS)

Now, one might say that this does not make an argument and so cannot argue fallaciously. As their spokesperson (roughly) says in the article, they are just getting people to "ask the question" and "think about why doing animal research is important." And that might be fair enough, even if it seems, perhaps, a bit disingenuous. But, it seems to me, even if we grant this, doing so should lead us to see that they expect us to infer something from our answer to this question. 

Perhaps it's just:

C: Killing the rat to save the little girl would be a good thing.

But, it seems unlikely that they are merely interested in agreement to such a limited conclusion. Presumably the girl and the rat represent a general claim about the value of the lives of cute little girls and rats. And, as an advocacy group, which lobbies against further restrictions on the use of animals in biomedical research (such as considering rats "animals" under the Animal Welfare Act, I believe) and defends research that kills and causes animals to suffer for possible medical benefits, it seems likely that they want us to infer something further from this premise. Perhaps,

P1: It would be better to save the girl than the rat.

C: The use of animals in research generally is good.

But, if someone were to infer that broader claim, as I suspect, the FBR would like, they would seem to be reasoning fallaciously.

The argument might also be taken as an argument from inconsistency:

P1: You hold that the use of animals for research is morally problematic. (70% of Americans do according to FBR).

P2: You would save a girl's life rather than a rat's life.

C1: Your belief in P1 is false

or, C2: You do not have good reason to hold your belief in P1

or, C3: You are an unreliable judge of the moral issue.

This is a better argument, and takes the form of a subjunctive tu quoque, of the fallacious variety–which conclusion should be drawn is unclear, but all of them seem non sequiturs.

On our analysis of subjunctive tu quoque's, the question is whether

P3: Your judgment in P2 is more relevant for judging the moral issue than whatever grounds you have in P1.

If this premise is supplied the argument looks less logically awful (for C2 at least), but P3 is unlikely to be true, making the argument at best unsound. Further as I noted above, it seems likely that the FBR would like the viewer to draw C1, which does not follow from the premises even with P3 supplied.

There are other things to say about the logic of the implicit arguments here, and my charity is running out. One might think, at the least, that it is curious that some would want to defend scientific research with bad arguments, but perhaps that's just my out-dated enlightenment views of science surfacing.

What to do about straw men

My sense has always been that careful and honest editors can spot most straw men.  But no.  On this score, via Leiter, here is an entertaining case in point.  The case is Gary Wills' negative review of Hubert Dreyfus and Sean Dorrance Kelly's "All Things Shining."  Drefyfus and Kelly feel they've been straw manned, they write:

Our book, All Things Shining, has clearly touched a nerve. Prominent reviewers have found it transformative. They have called it “fascinating,” “stunning,” “illuminating,” “inspirational,” and even a “harbinger of future philosophies to come.” But others have been outraged and dismissive. Garry Wills, the eminent historian and distinguished defender of the Catholic faith, now bears the standard for those arguing against. His recent review [NYR, April 7] expresses “astonishment” at how “inept” and “shallow” our book is, states that it is full of “silly” and “discredited” claims, and admonishes the “famous Big Thinkers” who, he thinks, have been duped by its wiles.

Many of the historical arguments Wills gives are reasonable, and his review would be fair if we actually held the positions he criticizes. Unfortunately, Wills regularly mistakes our views for discredited ones with which he is already familiar, and then, after reciting the well-known arguments against these discredited views, calls us “inept” for having spewed such “nonsense.” Some of our most sensitive and appreciative interlocutors disagree with the positions we articulate; but Wills seems simply not to understand them. 

This is a pretty serious charge.  Here is how Wills responds:

A lot of words, and no answers. I made specific charges, to which the authors make no specific replies. The only concrete point they make is that “we even give an example of Odysseus deliberating,” and for that they give no citation, either to their own book or to Homer. But I assume (after search) they are referring to page 76, which quotes (and rearranges) Fitzgerald’s translation on Odysseus’ “mind and spirit pondering” (Odyssey, 5.424). The verb here is hormainein (which Lattimore translates as “meditate”). They do not address the formulae of choice I adduced (dikha mermÄ“rizein, or entha kai entha mermÄ“rizein). They must not have wanted me to find their passage, since they gloss the verb as “pondering and despairing.” Odysseus is not undergoing the anguish of choice. He is, in their words, “busy despairing of his options.” Despair precludes choice—which does not matter, since Athena saves Odysseus with a whoosh.

Amid all their verbiage they say nothing about most of the points that I challenge—such as that Augustine was the first to join Christianity with Greek philosophy, or that he invented interiority by watching Ambrose read silently.

They do not even mention the matters that were most noticed as sacred “shining moments” in their book—the worship of Roger Federer’s tennis, the “praises of the Lord” for Demon Deacons, the canonization of Elizabeth Gilbert for submitting to the god of her own genius. They especially do not take the opportunity to explain, at last, their wildest idea—that carefully brewed coffee is a prophylactic against the “whoosh” of Hitler rallies. They vaguely dance away from all that with a dismissive claim that I am talking history and they are talking philosophy—as if philosophy were a warrant for making false statements, over and over.

I haven't read the book.  I didn't read Wills review either.  But it doesn't seem like Wills gets this criticism either.  Seems like a better reply would be: "no, I didn't straw man your view.  This is where you hold it."

Ad hominems and drawing conclusions about character

Ad hominem abusive fallacies are fallacies of relevance.  The basic scheme for the fallacy type is:

P1: S holds that p

P2: S has some vice, X

C1:  Therefore, p is false (or unacceptable).

With my informal logic classes, I have the regular joke: Just because Brenda is a heavy drinker, that doesn't mean that she doesn't know much about politics — She may be a heavy drinker because she knows politics!  That gets lots of laughs, believe me.  But now, consider an argument of a different form, but composed of similar propositions:

P3: p is demonstrably false (i.e., there is sufficient and easily accessible evidence that p is false)

P4: S holds that p, despite P3

C2: Therefore, S has some vice X (where X = vices from simple stupidity to willful ignorance to suffers from ideological thinking)

Importantly, the argument has very similar claims as the ad hominem abusive, but it is of a different form — we are reasoning to S's vice, not from it.  Now, it is clear that this second kind of argument can be made hastily (as there is a big difference between being wrong and being stupid — that's the Fallacy of No Reasonable Alternatives, a species of false dilemma), but it does seem right that P3 and P4 are relevant to C2.  This second form of argument is one either (a) addressed to some third party about S or (b) addressed directly to S in order to request that S reform how she performs in argument regarding p (and perhaps other issues).

With the theoretical apparatus assembled, let's look at Steve Chapman's column, "Why Birtherism is Here to Stay," over at TownHall.com. 

There has never been a shred of persuasive evidence that Obama was born anywhere but Hawaii. But thanks to rampant paranoia and widespread credulity, the myth of his foreign origins gained currency among many people who should know better.

What is Chapman's explanation for this phenomenon — people who believe things that they should know better to not?

A poll taken after the release of his birth certificate showed 18 percent of those who have seen it still aren't convinced.  Something about this president impels many people to accept anything that is said about him, as long as it's unfavorable. . . .   Birthers don't dislike Obama because they think he was born abroad. They think he was born abroad because they dislike him. People of this bent don't proceed from facts to a conclusion. They prefer to reach a conclusion and then scrounge for any facts — or "facts" — that support it.  For them, being told Obama is a natural-born American is like being told he's a loving father and a loyal friend. They won't buy it because it doesn't confirm what they want to be true.

The logician and pragmatist C.S. Peirce called these sorts of patterns of thought 'pseudoreasoning,' and it looks very much like a form of rationalizing.  And the key to the effectiveness of these strategies of thought is that the people making errors with them are not exposed to the consequences of being wrong.  If you pseudoreason your way to believing that you can fly, you pay the consequences.  But if you pseudoreason your way to believing that the President of the United States is a Muslim Marxist AntiChrist, you make lots of friends (and if you stop believing them, you lose those friends).

This is surprising only if you think of political views as a matter of logical reasoning. For many people, they really aren't. They're a way of indulging emotional impulses without suffering painful consequences. . . . [I]f thinking Obama is a foreigner brings you closer to people you like, you come out ahead. Birthers would rather be wrong than be divided from their allies. So the fiction that Obama was born in Kenya will endure, and many Americans will hold fast to a ridiculous article of faith that has been conclusively refuted.

The thing is that this does amount to calling Birthers credulous, ideological, and cognitively blind.  Chapman forgot one thing more for his piece: directing readers to the comments for this piece!

A circular argument against begging the question

A puzzle for the readers of the NonSequitur

Colin, John and I will be attending the upcoming Ontario Society for the Study of Argumentation (OSSA) conference in the coming weeks.  We're presenting a version of the Subjunctive Tu Quoque argument (Colin blazed the trail here). 

To the point, I'm slated to comment on a paper with the thesis that there are virtuous circular arguments.  I've posed a challenge to the author, with the following argument:

P1: There are no virtuous circular arguments.

C: Therefore, there are no virtuous circular arguments.

The challenge is to explain, if there are virtuous circular arguments, what is wrong with P1 being used to support C. Of course, the author doesn't get to say that P1 begs the question.

Is this out of bounds?  Moreover, if the challenge can't be met, what follows?

Tax quoque

Time to pay your federal taxes, so it's time for people to complain about how much we're taxed, or, alternatively, how little some people are taxed relative to their income, etc.  Now comes Gregg Easterbrook, whose work I do not know (and now I know why, if this is a measure of his intellect).  It is well known now that Barack Obama is for reductions in revenue expenditures–i.e., he's for increasing taxes (a phrase for which he was justly lampooned by Jon Stewart).  But, Easterbrook spies a problem:

President Barack Obama wants to increase taxes on the wealthy, and surely is correct that this must be part of any serious plan to control the national debt. Consider the case of a wealthy couple who made $1.7 million in 2010, yet paid only 26.2 percent in federal income taxes — though the top rate supposedly is 35 percent, and the president says that figure should rise to 39.6 percent. The well-off couple in question is Barack and Michelle Obama, whose tax returns, just released, show they paid substantially less than the president says others should pay.

If Obama is in earnest about wanting increased taxes on the wealthy, then he should send the United States Treasury $182,998. That’s the difference between his Form 1040 Line 60 (“This is your total tax”) and what he would have owed at the higher rate (plus limits on itemized deductions) he himself advocates.

So why doesn’t he tax himself more? The Form 1040, after all, only stipulates the minimum tax an American must pay. More is always welcome. Obama should write a check to the United States Treasury for $182,998.

Wealthy people who say the rich should pay higher taxes — Bill Gates and Warren Buffett have joined Obama in declaring this — are free to tax themselves. If you believe the top rate should rise to 39.6 percent (Obama) or 50 percent (Buffett), then calculate the difference and send a check for that amount to the Treasury. Of course no one individual doing this, even a billionaire, would have much impact on the deficit. But if rich people who say they believe in higher taxes were willing to practice what they preach, this would prove their sincerity, making legislation on the point more likely.

This argument is so dumb that Megan McArdle made it (can't remember where I read the refutation).  Normally, accusations of hypocrisy need to posit some actual or hypothetical (counterfactual) hypocrisy.

On Easterbrook's view, Obama is a hypocrite for not unilaterally taxing himself.  He's rich, he advocates higher taxes for the rich, ergo, ipso fatso.  But of course he's not a hypocrite, because he's advocating a tax policy he'll obey if given the chance.

As a practical matter, a bunch of rich people donating to the Treasury will likely delay tax increases on the wealthy–see, for instance, the free rider problem.

And, BTW, happy Charles Krauthammer Day!

Let them eat cake*

I'm pretty sure you can count on James Taranto to criticize Obama for abolishing medicare.  So it's not surprising when Obama points out that market pressures–namely high prices–ought to encourage people to take a little personal responsibility; the government, on Taranto's view perhaps, is not here to "feel their pain."  Or so one would think.  But, sadly, no (link courtesy of Sadly, No!):

At a town-hall meeting yesterday in Fairless Hills, Pa., a man in the audience asked Obama about gasoline prices, which are currently in the range of $4 a gallon. According to the Associated Press, Obama responded "laughingly" and "needled" the questioner. The president's sarcasm comes through in the White House transcript:

I know some of these big guys, they're all still driving their big SUVs. You know, they got their big monster trucks and everything. You're one of them? Well, now, here's my point. If you're complaining about the price of gas and you're only getting eight miles a gallon–(laughter)–you may have a big family, but it's probably not that big. How many you have? Ten kids, you say? Ten kids? (Laughter.) Well, you definitely need a hybrid van then. (Laughter.) . . .

So, like I said, if you're getting eight miles a gallon you may want to think about a trade-in. You can get a great deal. I promise you, GM or Ford or Chrysler, they're going to be happy to give you a deal on something that gets you better gas mileage.

The transcript shows that Obama got lots of laughs. But presumably he was speaking to a friendly audience–to people who regard the burning of gasoline as sinful and who, at least in theory, are attracted to the idea of $8-a-gallon gasoline.

People like that, to paraphrase Pauline Kael, live in a rather special world. For most Americans (we Manhattan residents are a notable exception), driving is a day-to-day necessity, and high gas prices are a constant source of economic pain. Sure, if you're driving a guzzler, it might make sense to trade it in. But not everyone has the money lying around to buy a new car at the drop of a hat. And owners of dinky cars and hybrids still have to buy gasoline for them.

The government is not here to solve the problem of high prices, one might argue.  Indeed, when the price of health care gas is high, the market will sort it out–and responsible people will make responsible choices about finite, expensive, but necessary resources.  They can't expect the government to sort it out.  Or at least, they will recognize the limitations.

Anyway, it goes without saying that Taranto has completely misrepresented the tone of the President's comments.  Here is a passage from the opener:

The fact is, for a lot of folks, money was already tight before gas prices started climbing, especially for some families where the husband or the wife had been out of work or you’ve had to get by with fewer customers or hours on the job. Having high gas prices is just one more added burden.

But I want everybody to remember, every time gases go up, we see the same pattern. Washington gets all worked up, just like clockwork. Republicans and Democrats both start making a lot of speeches. Usually the Democrats blame the Republicans; the Republicans blame the Democrats. Everybody is going in front of the cameras and they’ve got some new three-point plan to promise two-dollar-a-gallon gas. And then nothing happens. And then gas prices go down, and then suddenly it’s not in the news anymore and everybody forgets about it until the next time gas prices go back up again.

That’s what was happening when I was running three years ago. You remember “Drill, baby, drill”? That was because the economy was overheated, gas prices were skyrocketing, and everybody made a lot of speeches but not much happened. And I said then that we can’t afford to continue this kind of being in shock when gas prices go up and then suddenly being in a trance when things go back down again. We’ve got to have a sustained energy policy that is consistent, that recognizes that there’s no magic formula to driving gas prices down; it’s a steady improvement in terms of how we use energy and where we get energy from — that’s what’s going to make a difference. That’s how we’re going to secure our energy future.

It's as if he does feel their pain.  You can read the rest at the link–the link Taranto does not provide.  Wondering why.  And of course, his answer to the question about fuel efficiency is nothing like Taranto alleges.

 *a later edit included this title (I forgot to put a title on the original post).  I searching for the quoted Obama passage, I found scores of right-wing criticism of it (no surprise, it was repeated without context).  Surprising, however, that one called it Obama's "let them eat caek moment."  Now I wonder, isn't that just want conservatives would have the government do for health care, etc.?  I mean, how can Obama be a heartless French royal, and a communist with false beliefs about the environment trying to get us to drive fuel-efficient cars?
