When Uncle Ted said he shot the fuzzy bear

Comic and comedian
[comic, n.] 
...A comic actor; = comedian....
. . .
1961 J. McCabe Mr. Laurel & Mr. Hardy (1962) i. 38 ‘Stan,’ he said, ‘why do you want to be a comic?’  
—Oxford English Dictionary
     Whenever you enter into a dispute about the meaning of a word or phrase, you’ve entered a mine field. That’s partly because a word, even one approached as appearing in a snapshot of the present (as opposed to: as a thing traveling across time), doesn’t exist in one community but in many overlapping communities.
     And then there are philosophical issues that enter the picture. Sheesh.
     It’s easy to make a case that the noun “comic” and the noun “comedian” are synonyms. In making that case, however, you rely on standards that are clunky and insensitive: dictionaries and the like, things that require so much work that their issue is sporadic and occasional. There just isn’t the manpower to keep on top of swiftly moving subtleties, on so many fronts, in usage. (For instance, see the OED's definition of "begging the question" below.)
   
     CONSERVATIVES. People disagree about how to conceive the meaning of a word. Some tend to tie meanings down to some alleged essence: the “original” meaning or some “official” act of standardization by authorities. That approach isn’t always wrong (in my opinion), though (again, in my opinion), it usually is.
     That’s what I think anyway. More about that later.
     "Conservatives," in this narrow sense, are, of course, more liable to insist on the "correct" meaning of a term of phrase. If words have essences, and given that word meanings tend to change, well, then, obviously, there will be divergences from those essences and thus reasons to squawk.

     FREE-FLOATERS. In general, I’m happy to view meanings as detachable from any such essential basis. I certainly see the point of conservatism—insisting on a particular "real" meaning or distinction in the face of drift (or inadvertent invention) among the hoi polloi. For instance, there’s a good reason for maintaining the distinction between, say, “inferring” and “implying” when many others routinely obliterate the distinction.* And there's a good reason to maintain use of the word "phenomenon" to refer to any observable event—even as every element of popular culture (it seems) persists in using it to refer to the paranormal.
     Typically, in these struggles, the conservatives eventually loose to the masses, overwhelmed by shear usage. When that happens, continued conservatism is just silly.
     Take the “misuse” of the phrase “begging the question.” True, current usage is obliterating a valuable customary** meaning, thereby making the English language less rich and expressive. But the new usage is by now so familiar and widely accepted that, with few exceptions (e.g., my classroom), it is pointless to keep insisting on “the correct meaning.”

     RIGID DESIGNATION. When I was a philosophy student, a battle raged over how best to understand proper names. Are they disguised descriptions or are they “rigid designators”? That is, when I speak of Socrates, am I essentially referring to the teacher of Plato? (That’s a description, a "sense.") If so, then it would be nonsensical to suggest that Socrates never knew Plato. Necessarily, the "teacher of Plato" knew Plato.
     Alternatively, might it be that, in truth, “Socrates” refers (because it originally referred) to some humble, unreflective fisherman and, owing to a confusion, we’ve ended up referring often to this peasant, erroneously supposing that he was a great and influential philosopher (who taught the likes of Plato)? Here, the term is causally linked to the person originally "christened" with it, and thus no description is essentially tied to it. Accordingly, it is coherent (albeit controversial) to suggest that Socrates never knew Plato.
     This view may seem crazy but, in some instances, it seems correct.
The "fuzzy" look
     What would the “rigid designator” view (or at least its spirit) look like when applied to ordinary terms (common nouns, adjectives, etc.)? Well, just as “Socrates” has always referred to the original Socrates, even if, by now, our understanding of this individual is largely mistaken, term X—(say) the adjective “fuzzy”—originally was a particular description, and, though we may have drifted over time from that original description, the “actual” and "true" meaning is that original description.
     That's an absurd view. Suppose that, originally, “fuzzy” was used to say that a thing had spikes. But language changes, and now we have something else in mind by "fuzzy." Surely it would be a mistake to insist that, when Uncle Ted said he shot the fuzzy bear, he was “really” saying was that he shot a spiky bear. –No, he was saying (and he was "really" saying) that he shot that other kind of bear, the fuzzy kind. That the term "fuzzy" once meant "spiky" is simply irrelevant. The meaning of a term is what people mean by it, not what people long ago meant by it.
     (Of course, some scholarly communities comprise those who use terms fully cognizant of [at least some of] their histories. For them, subtly, word histories somewhat intrude on meaning—i.e., what they mean by words now. They play with words, gently sounding their histories, like strings on a guitar.)

     SEMI-CONSERVATIVES (SEMI-FREE-FLOATERS). I think that one could justify taking a semi-conservative view. Perhaps it’s like this: words (and phrases, etc.) tend to change in meaning over time, a phenomenon that (at least sometimes or to a degree) parallels natural selection, “improving” the language. But the process can also be insidious. Useful meanings (e.g., “begging the question”—as the phrase was used fifty years ago) are sometimes gradually erased in favor of a minor (or a non-) enrichment of the language. At such times, there's a net loss for the language. Under these circumstances, for the sake of maximal communication, especially within, say, some specialist group (philosophers, logicians), it would make sense to attempt to hold the line at least for a while (for the sake of clear and effective communication), to insist on the “traditional” meaning (i.e., the meaning they've recognized for a while, whether or not it was the "original" meaning). I used to do that in my philosophy classes. I was quite the traditionalist, word-wise.
     Suppose that one has lost the battle with regard to the "ordinary meaning" of the term. Suppose that efforts to preserve the once-traditional meaning of "begging the question" (BTQ) as "the" meaning are a failure. Virtually no one, outside a special group, recognizes the once-traditional meaning. The special group would of course preserve this (now) specialized meaning, though it would not insist on that meaning outside the narrow group.
     This appears to be the fate of the term "begging the question." What was once simply "the meaning" of BTQ becomes the meaning of BTQ only as a technical term. Meanwhile, owing to an error that became viral, a (non-technical) meaning of BTQ ("the" meaning in broader society) has been established.
     It’s still true, I think, that, among educated speakers, “infer” does not mean “imply,” and that’s a good thing, though it does separate people into the "educated" and the "uneducated." As college instructors, we engage in such segregations every day. As educators, we're part of a crew that participates in the enterprise of preserving the language and maintaining its power. Some publishers and publications, I think, view themselves as part of this crew. They do what they can as "Meaning Police." That's not always conservative. The MPs, while preserving the useful, can also admire innovation.
     Alas, as preservers of the useful (etc.), they are only slowing the inevitable. In time, of course, "infer" will simply mean "imply." The educated elite (if that group continues to exist) will probably have to throw in the towel and speak and mean like everyone else. To do otherwise would be ridiculous.

     Earlier, I suggested that one can make a “conservative” case for the synonymity of the nouns “comic” and “comedian.” Dictionaries will tend to support this position.
     I don't want to get into the weeds about the latter point. I'm thinking of a particular dispute.
     Yesterday, my mother, my sister, and I were discussing the old Ed Sullivan Show, a popular program that lasted until about 1970. Mom said that she watched some old episodes. She referred to the old "comics" on that show. She referred to one in particular, a woman.
     "Joan Rivers?" I asked.
     "Yes, she was one of them. But there was another one."
     We attempted to identify the comic. I mentioned all of the female comics I could think of from the 50s and 60s: Phyllis Diller, Totie Fields, et al. Mom wasn't thinking of any of those, she said. Eventually, knowing that my mother can use words eccentrically (for her, English is a second language), I decided to mention some comedians.
     "Are you thinking of someone like, say, Carol Burnett? Lucille Ball?" I asked.
     I added: "of course, they aren't really comics."
     Uh-oh.
     My mother looked at me blankly. My sister joined in this. "Of course they're comics!" said sis.
     No, I said. Burnett was a comedian all right, but she's wasn't a comic. Neither was Lucy.
     They were uncomprehending, or simply unconvinced. Luckily, the conversation ended there.
     So that's the dispute.

Uncle Ted and friend
     It’s easy to find people—estimable people—who insist that there is an important difference between the term “comic” and the term “comedian.” Comics are one group, comedians are a somewhat different group.
     Are they wrong and the lexicographers right?
     Here’s an example from someone from the world of stand-up comedy:
     A comic is a comedian; a comedian isn’t necessarily a comic. It’s the square and the rectangle argument (for nerds who remember geometry AND read this blog).
     This entry is dedicated to defining and understanding the differences between a comic, which is short for stand-up comic, and a comedian, who performs comical material.
     Stand-up comedy is the art of standing on stage and performing material to elicit laughs from the crowd.
. . .
     “Comedian” is a much broader term. A comedian is someone who performs comedic material in order to elicit laughs. This can be accomplished through acting in movies. Examples of movie actors who are comedians would be Bill Murray or Tom Hanks. It can be accomplished through funny songs, such as done by artists Weird Al Yankovic or Dr. Demento. A comedian can host a variety show, like Conan O’Brien or David Letterman. It can be established through a radio show, like Howard Stern. Comedians can also perform team improvisation/“improv”, like on “Who’s Line is it Anyway?” It can even be accomplished by doing stand-up comedy. Here’s where the square/rectangle argument comes into play.
       You’re considered a comedian if you’re doing any performance that gets a laugh, including stand-up comedy. However, you are ONLY considered a comic if you do stand-up comedy.
. . .
     …[S]tand-up comics develop unique skills in order to prep and deal with the live-audience environment. While being a comedian also involves a lot of skill and practice, the difference is dependent on having a cast, a script, and, often, being able to reshoot/re-do scenes that don’t work the first time. Ultimately, as a stand-up comic, if you fail on stage, the only person you have to blame is yourself. The flip side of this, of course, is that when you succeed on stage, the only person responsible and deserving of praise, adulation, and the great things that come with success is yourself. (Comic vs. comedian: what's the difference?)
     Here’s another example from someone outside the world of stand-up comedy (and even outside of the English speaking world!):
     Every comic — now a term exclusively reserved for stand-up — has had to face boos, catcalls, hecklers and even legal notices. (Comic Vs Comedian.)
     I think that these people are part of a community (or, in the second case, have significant exposure to such a community) where a particular distinction between “comic” (a kind of comedian) and “comedian” (the more general term) has come to exist and to be important. Without doubt, in their world, this difference in meanings exists.
     And the likes of me—we've tapped into that community's conversation, have to an extent adopted its language. My guess is that the larger society is gradually doing the same.
     But who knows.
     Does that make this usage correct and the approved “dictionary” usage incorrect? Well, yes and no. There are settings where I’d have to agree—"yes, for you people (scholars at Oxford?), 'comic' and 'comedian' are synonyms. There's no good reason why you should adopt this newer usage—though, of course, you should be aware of it, if you're going to listen to and communicate with those who are tapped into popular culture." (If they're Oxford dons, that's not likely to be the case.)
     But I would say that, being a non-conservative about such matters.

     *We can distinguish at least two different kinds of case: (1) There exists an established meaning (of X) and then, somehow, a new meaning crops up and competes with it (such seems to be the case with "begging the question"). Here, we're inclined to speak of "error" or perhaps neologism; (2) there are two distinct communities and one meaning (of X) is embraced by one community while another meaning (of X) is embraced by the other. I suspect that the "infer/imply" situation involves the second kind of case. The "educated" have their meaning; the uneducated have theirs. Neither error nor neologism is involved. Consider also the situation with regard to the distinction between inductive and deductive arguments—conceived differently between philosophers/logicians, on the one hand, and rhetoricians, on the other. (No, philosophers and logicians do not define a "deductive" argument as going from the general to the particular.) I have found that many philosophers/logicians are not shy about placing this particular meaning difference in a third category, related to the first: (3) changes (improvements) are made by the proper authorities in defining X but, unfortunately, some group persists in using the outdated meaning. See for example the Internet Encyclopedia of Philosophy, which asserts: "It is worth noting that some dictionaries and texts improperly define 'deduction' as reasoning from the general to specific and define 'induction' as reasoning from the specific to the general. These definitions are outdated and inaccurate."

     **Customs can exist in isolation, of course. The logician's use of the word "valid" has long been customary in philosophy/logic, but that custom is unknown to most speakers of the English language. As near a I can tell, the phrase "begging the question" long had its home in the fields of logic (etc.) and rhetoric. At about mid-century, however, persons outside those fields picked up the phrase, misunderstanding its meaning, giving it a new meaning. The new meaning spread like wildfire and is about to choke out the old one entirely. Now, there are very few places where I can say that a speaker or writer has "begged the question" (as logicians understand this) and be understood.

In defense of extremism (Part 1)

"Extremism in the defense of liberty is no vice; moderation in the pursuit of justice is no virtue."

.....—Barry Goldwater, 1964

A couple of days ago, I was watching news coverage of the Republican Convention in St. Paul, Minnesota. A reporter offered a minor segment on demonstrators who had been handled roughly by riot gear-equipped local police. The reporter seemed to dismiss the protesters’ views, noting briefly that they were “extremists.”

It was as though he were saying, “they’re just extremists, so we won’t bother explaining their beef with the Republicans.”

Why do we think in this way?

In this country, we seem to use the term “extremist” more or less descriptively: an “extremist” is one who holds a view that is at an extreme on the spectrum of views—with regard to politics, more or less.

I add “with regard to politics” because I do not think that most people would use the term “extremist” to refer to someone who, say, took an “extreme” religious view (such people are dismissed as “cultists”) or someone who, say, took an “extreme” view regarding diet, such as a vegan or “meatarian” (such people are dismissed as eccentrics, not as extremists).

Only some extreme views or activities are labeled “extremist,” then. Someone who seeks to overthrow the government is surely an extremist. A “radical” who destroys banks or sewers is an extremist.

Note that a prolific serial killer or “mad bomber” is not an extremist. Extremists need to have an agenda that is in some sense political or social. Extreme activity is not in itself extremism.

OK, so what do we think about these extremists? Well, clearly, we tend to "think" along these lines:

View (or activity) V is extremist.
Therefore V is beyond the pale.


But such reasoning is plainly defective. Our own (American) history provides ready examples of conduct and thinking that was once widely regarded as “extremist” but that eventually prevailed and is now embraced and insisted upon. Think of abolitionism, women’s suffrage, civil rights, and so on.

So history—our own history—teaches us that what is “extreme” one day can turn out to be “our way of thinking and living” later on. So why do we simply reject extreme views and philosophies?

One might argue that, though the occasional extremist view turns out to be “true” (or whatever we should call it), most extremist views are exactly as absurd as they seem (to many of us) to be, or at least that is the pattern historically.

I’m not sure that’s true, but let’s suppose that it is. What does the alleged factoid tell us? It certainly doesn’t tell us to reject extremist views out of hand. Doesn’t history tell us that we had better be careful not to assume that things that strike us as extreme and outrageous (or ridiculous, etc.) are really so? After all, in making that assumption, we run the risk—OK, the slight risk—of being among the bad guys—like slaveholders, wife beaters, child exploiters, racists, and all the other monsters we absolutely do not want to be.

It is unwise to run a slight but significant risk of catastrophe. Turning out to be like the KKK is surely a moral catastrophe.

The risk is not like the possibility of being hit by lightning. It is the possibility that we are vicious, that we are not trying hard enough, that we are dropping the ball, morally. If we are in error, then we can detect it; after all, we can think about what is right and good, what is wrong and wicked.

We don’t look back at slaveholders and judge them as simply having different values that were somehow wrong values. Rather, we look at them as in some sense having betrayed or failed to live by “our values.” So if an extremist comes along, we can stop and think about what he or she is saying. We should have the humility to recognize that we (who are not extremists) could be in error—we could be incautious or inattentive or stubborn, etc. We should try hard to live up to our values and not assume that that just happens by itself, without effort or thought.

Well, anyway, I can see no justification for simply rejecting extremist views out of hand. We at least need to think about them. Mill was right, I think, when he said that challenges to our thinking are good, for even when the challengers are utterly wrong-headed, by challenging us, they keep us thinking about the meaning and justification of what it is that we think and do. It's never a good idea to be comfortable, morally.

There is a kind of thinking that pops up here and there in our way of thinking according to which the truth is the middle between extremes. But, again, clearly, that is often not true. Anyone can come up with counterexamples.

People sometimes seem to think that it is not possible that either of the “two sides” in a dispute is totally in error. According to this thinking, when there is a dispute, each “side” has at least a piece of the truth, and, if we are wise, we will identify everybody's pieces.

Think of journalists who value “balance.” They drive me nuts.

Clearly, sometimes, one “side” is indeed fundamentally wrong and they are in possession of no piece of the truth. People who insist that the Earth is flat are very silly or disturbed. I’ve read their arguments. They’ve got nothing. Really. Nothing.

Imagine insisting that we must carefully consider their view in order to find that fragment of truth that they bring to the discussion. Consider Holocaust deniers. Is the truth about European history (from 1938 to 1945) some sort of blend of their take on history and the take according to which the Holocaust occurred?

* * * *

For me and some of my friends, both “sides” in the current contest over who should become President are pretty far off the mark. (For us, one side is regarded as much more benighted than the other; nevertheless, both “sides”—both the Democrats and the Republicans—are viewed as hugely mistaken about priorities and such.) We would argue, I think, that, sometimes, the only remotely acceptable view isn’t even on the horizon for most people.

Sometimes, I suggest that “we” should consider urging people to have fewer children. After all, virtually all of the major difficulties that challenge humanity (and the rest of the world!) are related to high human populations. And if we tweak the rate of children-production just a little bit, we actually lower population very rapidly. It wouldn't be hard to reduce the human population vastly in just two or three generations.

Generally, when I make this suggestion, I am regarded as having said something that is so outrageous that it can be rejected out of hand.

Why?

I'm sorry, but I'm onto something here. If we could just get people to see the advantages of smallish families—just as we are trying now to get people to see the value of "green living"—then all sorts of difficulties will be greatly ameliorated. Isn't that obvious?

It is frustrating to have no voice at all in so important a debate.

Another example: prima facie, the jury system, as it now exists, is ridiculous. Why can't voices demanding reform even get a hearing? (I'm not sure this view even qualifies as "extremist." Sometimes, I think that what we tend to reject isn't extremism; rather, it is common sense.)

* * *

I have never understood people's reactions to those who resort to violence in combating abortions. I do not think of (most) abortions as the murder of infants. But if I did think that, then I would be horrified by what goes on in abortion clinics. I would be inclined to use terms like "Holocaust." Why wouldn't I?

And, being intelligent, I would realize that there is virtually no hope that a significant number of my fellow citizens will see the situation as I do—as a Holocaust. I would be placed in a terrible moral predicament, for I would have essentially no prospects of stopping the murders through the political process. I would find myself living in a hellish world of terrible violence. (It is easy for people who care about the pain of animals to feel exactly this way.)

When anti-abortionists bomb clinics, I understand that. I don't agree with them that these clinics are committing murders. But I do understand why they resort to violence. I think we should really listen to these people and at least let them know that we sympathize with their plight, even if we don't agree with their premise.

It must drive them mad, being simply dismissed as extremists. But how can they do nothing?

Without data, we only have a bloke*

"A little song, a little dance, a little seltzer down your pants." —Chuckles the Clown (Mary Tyler More Show)

Now, lots of folks in academia claim to teach "argumentation"—how to argue. But they aren't always teaching the same things.

It has long struck me as odd that, while philosophers teach their students that facts about an arguer are irrelevant (this is the essence of their teachings re the "ad hominem" fallacy), writing and speech instructors often seem to teach the opposite, for they make a great point of the importance, for the writer or speaker (the arguer), of presenting himself in a certain way: as reasonable, knowledgeable, etc.

The explanation of this difference, of course, concerns the different purposes these people have. The philosopher/logician seeks the truth and thus teaches students how to seek the truth. Hence, he focuses on evidence and reasons—what writing instructors call "logos" or the "logical appeal." He is not concerned with "pathos" or "ethos"—i.e., the emotional appeal or the appeal that derives from how the writer presents himself.

Writing instructors, however, are more about effectiveness (or persuasion) than truth, and so, for them, "logic" is just one tool among several. For instance, if you want to convince your readers of something—say, that John McCain is too addled to be President—then, assuming they aren't very logical (usually a safe assumption), you'd be a fool to offer mere logic. Reasons and evidence? Most audiences will become bored with that; they'll walk away. Better get out the blooper reel. (See Why we need rhetoric.)

Philosophers, as philosophers, are happy to have people walk away. They want to know the truth, and knowing the truth has nothing to do with having lots of eager listeners or readers. (Indeed, folks who seek the truth invariably become very nervous when their ideas become attractive to others.)

Roughly speaking, writing instructors are unhappy when the audience (or the "reasonable" among the audience) walks away. And so they spend a good deal of time talking about the importance of presenting yourself properly, i.e., effectively. (Ironically, writing and speech instructors can trace their body of theory to the writings of a philosopher/logician, but one who held audiences in low esteem. See Aristotle's rhetoric.)

Um, but if your readers buy that, they're committing a fallacy, right?

—Oh, absolutely. Great. Now show us Obama Girl!

A recent column by Ben Oldacre (in the Guardian: Testing the plausibility effect) concerns what happens when audiences focus on how a speaker presents himself (ethos) without focussing on his evidence and reasons (logos). He notes the case of a Dr. Somebody, an impressive government advisor, who claimed to have done a study that showed that a recent spate of suicides all lived close to a mobile home mast. After a few phone calls, Oldacre determined that Somebody wasn’t a doctor, wasn’t a government advisor, and he had lost his data:

Without data, we have only a bloke. Week in, week out, we see apparently scientific claims being made in the newspapers with great confidence, as if they were based on evidence, when in reality they are based on nothing more than authority, and often from one man. This is because science is communicated to the public by journalists, who sometimes have no understanding of what it means for there to be evidence for an assertion. They are impressed by enthusiasm, long words, by a PhD, a white coat, or a medical qualification. [My emphasis.]

Oldacre recalls an experiment performed in the early 70s. Researchers hired a man to play the role of an authority “on the application of mathematics to human behaviour.” In fact, the man knew nothing about the subject. They gave him an impressive fake CV. They had him give a presentation at an academic conference on medical education. His lecture and Q&A was filled with “double talk, jargon, dubious neologisms, non sequiturs, and mutually contradictory statements.”

The lecture was a hit. They tried the charade several times. They always got the same result.

My advice? Let's start teaching students what is relevant and what is not. We're drowning in illogic.

* * * * *

[Thomas Hobbes] maintains that the establishment of ethos is an irrelevance not merely in the natural sciences…but in the moral sciences as well. His translation of Aristotle’s Art of Rhetoric accordingly omits the entire section in which Aristotle speaks of the crucial importance of taking steps to make a good impression on one’s audience.

—From Reason and Rhetoric in the Philosophy of Hobbes, Quentin Skinner

“A second type of … argument is the speaker’s character, not only as established by his reputation, but also as conveyed in the speech itself. Most orators agree that one’s character is the most potent weapon in one’s rhetorical arsenal.”
