Using the attached chapter 3: Critical Thinking E-bookWrite an argumentative paper of no more than 750
words that demonstrates why globalization is good or not good for a
business. The paper should define the term good, and should identify the premises and conclusions. Identify the premise and conclusion by placing a number in bold at the beginning of the sentence with the word premise or conclusion. For example: (1, Premise), (2, Premise), (1, Conclusion), (2, Conclusion), and so on.
Sentences labeled as “1, premise” are premises for the sentence labeled as “1, conclusion.”All premises should be labeled for each conclusion in the article.
If a sentence is a conclusion and a premise for another conclusion,
place two labels.At the end of the paper, identify one example of how you used
deductive reasoning and one example of how you used inductive reasoning.

rom August 1987 until January 2007, Alan Greenspan was chairman of the Federal Reserve
Board (“the Fed”). Because any remark he made about U.S. monetary policy could cause
markets all over the world to fluctuate wildly, he developed a complicated way of speaking that
came to be known as “Fedspeak.”
Here’s an example:
It is a tricky problem to find the particular calibration in timing that would be appropriate to

stem the acceleration in risk premiums created by falling incomes without prematurely
aborting the decline in the inflation-generated risk premiums.*
Greenspan has admitted that such remarks were not really intended to be understood.
Asked to give an example by commenting on the weather, Greenspan replied,
I would generally expect that today in Washington, D.C., the probability of changes in the
weather is highly uncertain. But we are monitoring the data in such a manner that we will be
able to update people on changes that are important.*
Page 70

This tells us nothing about the weather, of course, and was not intended to. Many times, though, we run
across similarly complicated examples of speech or writing that do seem to be intended to inform us.
For example, Allan Bloom, the famous American educator who authored The Closing of the
American Mind, which was read (or at least purchased) by millions, wrote in that book:
If openness means to “go with the flow,” it is necessarily an accommodation to the present.
That present is so closed to doubt about so many things impeding the progress of its principles
that unqualified openness to it would mean forgetting the despised alternative to it, knowledge
of which makes us aware of what is doubtful in it.
Is this true? Well—that’s really hard to say. The problem is, you don’t know exactly what Professor
Bloom is asserting in this passage.
Those who survived the San Francisco earthquake said, “Thank God, I’m still alive.” But, of course, those who
died—their lives will never be the same again.
—U.S. SENATOR BARBARA BOXER (D), California
Any number of problems may make a statement unclear. Not infrequently, people just don’t say
what they mean. Consider this statement made by President George W. Bush:
You know, when you give a man more money in his pocket—in this case, a woman more
money in her pocket to expand a business, it—they build new buildings. And when somebody
builds a new building somebody has got to come and build the building. And when the
building expanded it prevented additional opportunities for people to work. (Lancaster, PA,
October 3, 2007)**
If I said anything which implies that I think that we didn’t do what we should have done given the choices we faced
at the time, I shouldn’t have said that.
—BILL CLINTON (reported by Larry Engelmann)
We think he meant “presented” rather than “prevented,” but even then, the point can surely be made
more clearly. Here’s an example from former Canadian prime minister Jean Chrétien, when asked in
Parliament about old versus new money in the health care program:
They say that the money we had promised three years ago to be new money this year is not
new money. We have not paid it yet and it is old money versus new money. For me new
money is new money if paying in $5 or $10, it’s the same money.†
We have no clue what he had in mind.
One of your authors noticed this as a tease on the front page of a newspaper: “49ers are upset.” This
probably means that somebody who was not supposed to beat the San Francisco football team did
manage to beat them. On the other hand, it could mean that the team is dismayed about something.

Although obscurity can issue from various causes, four sources of confusion stand out as
paramount: excessive vagueness, ambiguity, excessive generality, and undefined terms. In this chapter,
we shall consider vagueness, ambiguity, and generality in some detail and then talk about definitions.
Also, from time to time situations arise in which we need to think critically about what we write,
especially when we are trying to produce an argumentative essay. In this type of writing enterprise, one
takes a position on an issue and supports it with argument. A good argumentative essay usually consists
of four parts: a statement of the issue, a statement of one’s position on that issue, arguments that support
one’s position, and rebuttals of arguments that support contrary positions. Obviously, an argumentative
essay is weakened by statements that are obscure, and what we say in this chapter has direct application
to writing clear argumentative essays. We shall return to this subject after we discuss vagueness,
ambiguity, generality, and definitions.

VAGUENESS
Perhaps the most common form of unclear thinking or writing is excessive vagueness. Pursued to its
depths, the concept of vagueness can be a knotty one, and it has been the focus of much philosophical
attention in the past few decades.* Fortunately, at a practical level, the idea is not difficult to grasp. A
word or phrase is vague if the group of things to which it applies has borderline cases. Consider the
word “bald.” It’s clear that Paris Hilton is not bald. It’s equally clear that Patrick Stewart is bald. But
there are lots of people in between (including both your authors). Many of those between the two
extremes are borderline cases: It is not at all clear whether the word “bald” should apply to them—it’s
the sort of thing about which reasonable people could disagree. For this reason, it is correct to say that
baldness is a vague concept.

Real Life
Vagueness at the Border
As the text explains, vagueness results when the scope of a concept is not clear—that is, when
there are borderline cases. “Bald” is a typical example. Here, Ms. Hilton is clearly not bald, and
Mr. Stewart clearly is bald. But whether Bruce Willis is bald or not is a good question. He has
hair—although it seems to be on the wane—but these days, he keeps his head shaved and thus
appears bald. How much hair would he have to lose to be bald whether or not he shaved his
head? The fact that there is no good answer demonstrates that “baldness” is a vague concept.
Man is ready to die for an idea, provided that idea is not quite clear to him.
—PAUL ELDRIDGE
Vagueness plays a very important role in much that we do. In the law, for example, how we deal
with vagueness is crucial. Whether the word “torture” applies to various types of interrogation
techniques, especially including “waterboarding,” for example, has been a serious issue for several
years. Many former officials have claimed that these techniques did not count as torture, but many
others have disagreed. (Some, who subjected themseves to the procedure, have disagreed rather
violently.) Possibly more relevant to us and to you personally, whether a bit of driving is “reckless” or
not may determine whether you pay a small fine or a large one—or even go to jail. Consider, too, the
speed limits we are asked to observe on the highways. Ideally, the offense in question would be
something like “driving too fast for the circumstances” rather than driving faster than a particular speed.
This is because what is safe at 80 miles per hour in one set of circumstances (midday, no traffic, clear
weather, and dry roads) might be dangerously unsafe at 40 miles per hour in another (dark, heavy traffic,
rain or fog, slick roads). But we have opted for set speed limits because “driving too fast” is a vague
term, and we do not want to put our fate in the hands of patrol officers and judges who are in a position
to make arbitrary decisions about whether it applies in our case. So, because we are afraid of the
2/9/2016 12:17 PM
consequences of the vague concept, we sometimes get away with driving dangerously fast under bad
circumstances, and we are sometimes ticketed for driving over the posted limit when it is quite safe to
do so.

Everything is vague to a degree you do not realize until you have tried to make it precise.
—BERTRAND RUSSELL
Sometimes vagueness is just annoying. Suppose that it’s late and you’re looking for someone’s
house and you’re given the following directions: “Go on down this street a ways ’til you get to the first
major intersection, make a sharp right, then, when the street starts to curve to the left, you’ll be there.”
The vagueness in these directions is as likely to get your blood pressure up as it is to help you find your
destination. (How do you decide that a particular intersection is “major,” for example?)
Vagueness is often intentional, used as a means to avoid giving a clear, precise answer. Politicians
often resort to vague statements if they don’t want their audience to know exactly where they stand. A
vague answer to the question “Do you love me?” may mean there’s trouble ahead in the relationship.
Ask a man which way he is going to vote, and he will probably tell you. Ask him, however, why, and vagueness is
all.
—BARNARD LEVIN
Vagueness occurs to varying degrees, and it is difficult to the point of impossibility to get rid of it
entirely. Fortunately, there is no need to get rid of it entirely. We live very comfortably with a certain
amount of vagueness in most of what we say. “Butte City is a very small town” presents us with no
problems under ordinary circumstances, despite the vagueness of “very small town.” “Darren has no
school loans because his parents are rich” doesn’t tell us how much money the parents have, but it tells
us enough to be useful. “Rich” and “small,” like “bald,” are vague concepts; there is no accepted clear
line between the things to which they apply and those to which they don’t. Nonetheless, they are
valuable notions; we get a lot of good use out of them.
Problems arise with vagueness when there is too much of it, as in our direction-giving example
above. Similarly, if a politician claims he will “raise taxes on the wealthy,” what should we take that to
mean? Unlike with the earlier example of Darren’s rich parents, in this case it would be worthwhile to
spend some effort trying to pin down just what our speaker means by “wealthy,” since where the borders
fall here really do make a difference.
So, when is a level of vagueness acceptable and when is it not? It’s difficult to give a general rule,
aside from urging due care and common sense, but we might say this: When a claim is not too vague to
convey appropriately useful information, its level of vagueness is acceptable. For example, if the
directions we’re given are not too vague to help us find our destination, they pass the test. If the
politician specifies enough about his tax plan to assure us that we understand how it would apply, then
we should not complain of vagueness. But when a speaker or writer does indulge in excessive
vagueness, thereby making it difficult or impossible for us to fairly assess his or her claim, it is our job
to hold that person accountable.

Asked why the desertion rate in the army had risen so much, director of plans and resources for Army personnel
Roy Wallace replied, “We’re asking a lot of soldiers these days.”
You might at first want to know what they’re asking the soldiers, until you see the ambiguity in Wallace’s remark.
AMBIGUITY
A word, phrase, or sentence is said to be ambiguous when it has more than one meaning. Does “Paul
cashed a check” mean that Paul gave somebody cash, or that somebody gave cash to him? It could mean
either. “Jessica is renting her house” could mean that she’s renting it to someone or from someone.
Jennifer gets up from her desk on Friday afternoon and says, “My work here is finished.” She might
mean that she has finished the account she was working on, or that her whole week’s work is done and
she’s leaving for the weekend, or that she’s fed up with her job and is leaving the company. If you look
online, you can find several collections of amusing headlines that are funny because of their ambiguity:
“Kids make nutritious snacks,” for example, or “Miners refuse to work after death.”
Most of the time the interpretation that a speaker or writer intends for a claim is obvious, as in the
case of these headlines. But ambiguity can have consequences beyond making us smile. Take a look at
the box “A Subtle Ambiguity.” The question Russert asks is ambiguous, although you might not notice it
at first. It could be a question about the cause—that is, the explanation—for one’s not supporting gay
marriage, or it might be about his reasons—that is, his argument—for not supporting it. Presidential
candidate Edwards took advantage of the ambiguity to duck the question Russert really wanted him to
answer, which was the second version. The way Edwards was brought up is something he is not
responsible for and which he does not have to defend. On the other hand if he were asked to give
arguments for his side of the issue, he could then be asked to defend those arguments.

Brad and Angelina are not pleased with this book. Of course, they aren’t displeased, either, since it’s
almost certain they’ve never heard of it. Note the ambiguity in the original statement.
In discussions of gay rights, we’ve seen an ambiguity in the term “rights” that often stymies
rational debate. The issue is whether laws should be passed to prevent discrimination against gays in
housing, in the workplace, and so forth. One side claims that such laws would themselves be
12 of 56
2/9/2016 12:17 PM
13 of 56
discriminatory because they would specifically grant to gay people rights that are not specifically
guaranteed to others—they would be “special” rights. The other side claims that the laws are only to
guarantee for gays the right to be treated the same as others under the law. When the two sides fail to
sort out just what they mean by their key terms, the result is at best a great waste of breath and at worst
angry misunderstanding.
Semantic Ambiguity
A claim can be ambiguous in any of several ways. The most obvious way is probably by containing an
ambiguous word or phrase, which produces a case of semantic ambiguity. See if you can explain the
ambiguity in each of the following claims:
1. Wingo, the running back, always lines up on the right side.
2. Jessica is cold.
3. Aunt Delia never used glasses.

The story goes that a burglar and his 16-year-old accomplice tripped a silent alarm while breaking into a building.
The accomplice was carrying a pistol, and when police arrived and tried to talk him out of the weapon, the older
burglar said, “Give it to him!” whereupon the youngster shot the policeman.
—Courtesy of COLLEN JOHNSON, currently of the California State Prison, Tehachapi
Ambiguity can be dangerous!
In the first case, it may be that it’s the right and not the left side where Wingo lines up, or it may be that
he always lines up on the correct side. The second example may be saying something about Jessica’s
temperature or something about her personality. In the third case, it may be that Aunt Delia always had
good eyes, but it also might mean that she drank her beer directly from the bottle (which was true of one
of your authors’ Aunt Delia). Semantically ambiguous claims can be made unambiguous
(“disambiguated”) by substituting a word or phrase that is not ambiguous for the one making the trouble.
“Correct” for “right,” for example, in #1; “eyeglasses” for “glasses” in #3.
Grouping Ambiguity
There is a special kind of semantic ambiguity, called grouping ambiguity, that results when it is not
clear whether a word is being used to refer to a group collectively or to members of the group
individually. Consider:
Secretaries make more money than physicians do.
The example is true if the speaker refers to secretaries and physicians collectively, since there are many
more secretaries than there are physicians. But it is obviously false if the two words refer to individual
secretaries and physicians.
“Lawn mowers create more air pollution than dirt bikes do” is something a dirt biker might say in
defense of his hobby. And, because it is ambiguous, there is an interpretation under which his claim is
probably true as well as one under which it is probably false. Taken collectively, lawn mowers doubtless
create more pollution because there are so many more of them. Individually, we’d bet it’s the dirt bike
that does more damage.
“I asked my mother if I were a gifted child. She said they certainly would not have paid for me.”
—-ANONYMOUS
Like other types of ambiguity, grouping ambiguity can be used intentionally to interfere with clear
thinking. A few years ago, federal taxes were increased, and opponents of the change referred to it as
“the biggest tax increase in history.” If true, that makes the increase sound pretty radical, doesn’t it? And
it was true, if you looked at the total tax revenue that was brought in by the increase. But this result was
largely due to the numbers of people and the circumstances to which the increase applied. If we look at
the percentage increase paid by individual taxpayers, this was not the biggest increase in history. Since
most of us are mainly interested in how much more we as individuals have to pay, it is the latter
interpretation that is usually more important. But the grouping ambiguity underlying the phrase “the
biggest tax increase in history” allows one to give another interpretation under which the claim is true;
although the individual tax increases were not the biggest, the collective tax increase was.

This package of doggie diapers (we’re not kidding) must never have been given a critical look. A
well-placed hyphen would make clear what the advertisers meant to say. (Thanks to Consumer
Reports for the example.)
There are two venerable fallacies based on the grouping type of ambiguity. Each involves taking
the ambiguity one step further than we’ve done so far. A person commits the fallacy of division when
he or she reasons from the fact that a claim about a group taken collectively is true to the conclusion that
the same claim about members of the group taken individually is also true. In 1973, the Miami Dolphins
were undefeated for the entire NFL football season and went on to win the Super Bowl in early 1974.
Nobody disputes the fact that the team was the best in the league that year. Does it follow that the
individual players on that team were the best players in the league? That is, that Bob Griese was the best
quarterback, Larry Csonka the best running back, Mercury Morris the best receiver? No, of course not.
What is true of the whole may not be true of each individual part. A round building, remember, does not
have to be built of round bricks.

In Depth
Composition and the First Cause Argument
Here is a brief version of an old and famous argument for the existence of God. It is known as
the first cause argument.
Premise: Everything had to have been caused.
Therefore: The universe, too, had to have been caused.
And therefore: God, the cause of the universe, exists.
This argument, at least this version of it, can be analyzed as an example of the fallacy of
composition. Do you see how to analyze it this way?
Going the other direction, a person commits the fallacy of composition when he or she reasons
from the fact that each member of a group has a certain property to the conclusion that the group as a
whole must have that property. An example: At the current moment (and it is true most of the time, in
fact) in their various states and districts, individual members of Congress receive fairly high marks in
opinion polls. One might therefore think that opinion polls would give Congress as a whole fairly high
marks. But this would be a mistake, since Congress in general gets very low marks in these same polls.
The way people feel about the parts is not necessarily what they feel about the whole. To turn our earlier
example around: You can use rectangular bricks to build a building that is not rectangular.
You’ll find other examples of these two fallacies in the following “In Depth” box.
Syntactic Ambiguity
Syntactic ambiguity occurs when a claim is open to two or more interpretations because of its
structure—that is, its syntax. Not long ago, one of us received information from the American
Automobile Association prior to driving to British Columbia. “To travel in Canada,” the brochure stated,
“you will need a birth certificate or a driver’s license and other photo ID.”
Just what is the requirement for crossing the border? Under one interpretation, you have to take a
photo ID other than a birth certificate or a driver’s license, and under another, you don’t. If we group by
brackets, we can make the two interpretations clear, we hope:

More Examples of the Composition and Division Fallacies
Division: “A balanced diet consists of the right proportion of protein, carbohydrates, and fat.
Therefore, each meal should consist of the same proportion of protein, carbohydrates, and fat.”
—DR. NICHOLAS PERRICONE, author of the best-selling book The Wrinkle Cure
Mistake: The balance necessary for a daily intake is not necessary for each part of one’s daily
intake—that is, each meal.
Division: After the 2008 elections, the Democrats took over both the U.S. Senate and the
House of Representatives. A number of pundits characterized the election by saying “the
voters have overwhelmingly voted for a Democratic Congress.”
Mistake: It’s true that voters collectively voted for a Democratic Congress, but voters
individually did no such thing. No person anywhere voted for a Democratic Congress, since
the issue did not appear on any ballot anywhere.
Composition: “The Kings don’t have a chance against the Lakers. The Lakers are better at
every position except power forward.”
—CHARLES BARKLEY
Mistake: Individual players, however talented, may not play that well together.
1. [You will need a birth certificate or a driver’s license] and [other photo ID]
2. [You will need a birth certificate] or [a driver’s license and other photo ID]
Neurosis is the inability to tolerate ambiguity.
—SIGMUND FREUD
Okay. But it’s still true that we should not have to live with too much of it!
The problem with the original version of the claim is that, because of its poor construction, we don’t
know whether to associate the driver’s license requirement with the birth certificate (as in interpretation
1) or with the “other photo ID” (as in interpretation 2). Rewriting is the key to eliminating syntactic
ambiguity. Depending on the intended interpretation, the original could have been written:
1. You will need either a birth certificate or a driver’s license and you will also need an additional
photo ID.
Or
2. You will need either a birth certificate or both a driver’s license and an additional photo ID.
Neither of these is ambiguous.

In the previous example, the problem was produced by a failure to make clear how the logical
words “or” and “and” were to apply. * Here are some other examples of syntactic ambiguity, along with
various possible interpretations, to help you get the idea.

Players with beginners’ skills only may use Court 1.
In this case, we don’t know what the word “only” applies to. This word, as we’ll see in later
chapters, is both very useful and very easy to use incorrectly. Here, it might mean that beginners may
use only Court 1. Or it might mean that players with only beginners’ skills may use Court 1. Finally, it
might mean that only players with beginners’ skills may use Court 1. Obviously, whoever puts up such a
sign needs to be more careful. (And so does the person who put up a sign in our university’s student
union that said, “Cash only this line.” Do you see the ambiguity?)
Susan saw the farmer with binoculars.
This ambiguity results from a modifying phrase (“with binoculars”) that is not clear in its application.
Who had the binoculars in this case? Presumably Susan, but it looks as though it was the farmer.
“Looking through her binoculars, Susan saw the farmer” clears it up.
People who protest often get arrested.
This is similar to the previous example: Does “often” apply to protesting or to getting arrested?
There’s somebody in the bed next to me.
Does “next to me” apply to a person or to a bed? One might rewrite this either as “There’s somebody
next to me in the bed” or as “There’s somebody in the bed next to mine.”
Ambiguous pronoun references occur when it is not clear to what or whom a pronoun is supposed
to refer. “The boys chased the girls and they giggled a lot” does not make clear who did the giggling.
“They” could be either the boys or the girls. A similar example: “After their father removed the trash
from the pool, the kids played in it.” A less amusing and possibly more troublemaking example: “Paul
agreed that, once Gary removed the motor from the car, he could have it.” What does Gary have
permission to take, the motor or the car? (Just imagine a written agreement containing this sentence.
We’d predict a lawsuit.) It pays to be careful; a speaker or writer who is thinking critically will make
clear exactly what he or she means to say.
On Language
Making Ambiguity Work for You
Have you ever been asked to write a letter of recommendation for a friend who was, well,
incompetent? To avoid either hurting your friend’s feelings or lying, Robert Thornton of Lehigh
University has some ambiguous statements you can use. Here are some examples:
I most enthusiastically recommend this candidate with no qualifications whatsoever.
I am pleased to say that this candidate is a former colleague of mine.
I can assure you that no person would be better for the job.
I would urge you to waste no time in making this candidate an offer of employment.
All in all, I cannot say enough good things about this candidate or recommend the

candidate too highly.
In my opinion, you will be very fortunate to get this person to work for you.

There are other examples of ambiguity that are difficult to classify. For example, one of us was at
lunch with the dean of a college at our university, and the dean said to the waiter, “You can bring the
sauce separately, and I’ll put it on myself.” The ambiguity, obviously, is in how he’ll put the sauce on
versus where he’ll put it. As in all cases of ambiguity, it is important to see that the claim is ambiguous
rather than to be able to classify the type of ambiguity. (This one could be called either semantic or
syntactic, by our lights.) By improving your ability to notice when claims are ambiguous, you will be
less likely to be misled by them and less likely to mislead others by using them—unless, of course, you
mean to mislead them!
GENERALITY
We turn now to the notion of generality, which is closely related to both vagueness and ambiguity and
which can cause trouble in the same way they do.
The traveler must, of course, always be cautious of the overly broad generalization. But I am an American, and a
paucity of data does not stop me from making sweeping, vague, conceptual statements, and, if necessary, following
these statements up with troops.
—GEORGE SAUNDERS, The Guardian, July 22, 2006
From what we learned of vagueness, we realize that the word “child” is vague, since it is not clear
where the line is drawn between children and non-children. It can also be ambiguous, because it can
refer not only to a person of immature years but also to a person’s offspring. As if this weren’t enough, it
is also general because it applies to both boys and girls. Roughly speaking, the less detail a claim
provides, the more general it is. Regarding specific words and phrases, the more different kinds of Xs to
which a word applies, the more general the word “X” is. “Moore has a dog” is more general than
“Moore has an otterhound.” “Moore has a pet” is still more general.
If you learn that Clarence has an arrest record, it may well lower your estimate of him and may
prevent you from hiring him to do work around your house, for example. But if some more detail were
supplied—for instance, that he had been arrested during a protest against a company that was polluting
the local river—it might well make a difference in your opinion of him. The difference between a very
general description and one with sufficient detail can be crucial to nearly any decision.
There has been a lot of discussion about whether the War on Terror should really be called a “war”
at all. The phrase has continued to be used because “war” is both vague and general. Some believe that
the word as traditionally used requires an enemy that is organized and identifiable, such as a country or
province, and those are difficult to identify in the War on Terror. Still less-clearly a war is the so-called
“War on Drugs.” This seems to be a purely metaphorical use of the word “war,” meant to show that
somebody is serious about the issue.
We don’t mean to confuse you with these closely related and overlapping pitfalls—vagueness,
ambiguity, and generality. In practical fact, it is less important that you classify the problem that infects a
claim or idea than that you see what’s going on and can explain it. For example, “Just what do you mean
by ‘war’?” is a good response to someone who is using the word too loosely. In some of the exercises
that follow, we’ll ask you to identify problems in different passages in order to help you become familiar
with the ideas. In others, we’ll simply ask you to explain what is needed for clarification.

Anyhow, with all these potential pitfalls to clear thinking and clear communication, what is a
critically thinking person to do? To start, we can do the best we can to be clear in what our words mean.
So after the following exercises we will turn our attention to the definition of terms.
Here are several exercises to give you practice identifying precision (or lack thereof) in sentences.
Exercise 3-1
The lettered words and phrases that follow each of the following fragments vary in their
vagueness and/or generality. In each instance, determine which is the most precise and
which is the least precise; then rank the remainder in order of precision, to the extent
possible. If these exercises are discussed in class, you’ll discover that many of them leave
room for disagreement. Discussion with input from your instructor will help you and
your classmates reach closer agreement about items that prove especially difficult to
rank.
Example
Over the past ten years, the median income of wage earners in St. Paul
a. nearly doubled
b. increased substantially
c. increased by 85.5 percent
d. increased by more than 85 percent
Answer
Choice (b) is the most general (vague is okay, too) because it provides the least
information; (c) is the most precise because it provides the most detailed figure. In
between, (d) is the second most precise, followed by (a).
1.
Eli and Sarah
a. decided to sell their house and move
b. made plans for the future
c. considered moving
d. talked
e. discussed their future
f. discussed selling their house
2. Manuel
a. worked in the yard all afternoon
b. spent the afternoon planting flowers in the yard
c. was outside all afternoon
d. spent the afternoon planting salvia alongside his front sidewalk
e. spent the afternoon in the yard
3. The hurricane that struck South Carolina
a. caused more than $20 million in property damage
2/9/2016 12:17 PM
23 of 56
b. destroyed dozens of structures
c. was severe and unfortunate
d. produced no fatalities but caused $25 million in property damage

4.
The recent changes in the tax code
a. will substantially increase taxes paid by those making more than $200,000 per
year
b. will increase by 4 percent the tax rate for those making more than $200,000 per
year; will leave unchanged the tax rate for people making between $40,000 and
$200,000; and will decrease by 2 percent the tax rate for those making less than
$40,000
c. will make some important changes in who pays what in taxes
d. are tougher on the rich than the provisions in the previous tax law
e. raise rates for the wealthy and reduce them for those in the lowest brackets
5. Smedley is absent because
a. he’s not feeling well
b. he’s under the weather
c. he has an upset stomach and a fever
d. he’s nauseated and has a fever of more than 103°
e. he has flulike symptoms
Exercise 3-2
Which of each set of claims is more precise (i.e., suffers least from vagueness, ambiguity,
or generality)?
Example
a. The trees served to make shade for the patio.
b. He served his country proudly.
Answer
The use of “served” in (b) is more vague than that in (a). We know exactly what the
trees did; we don’t know what he did.

DEFINING TERMS
When today’s typical student hears the word “definition,” we wouldn’t be surprised if the first thing to come to
mind is television. “High definition” is the new standard of clarity in what we see on the home screen. This is
directly analogous to the clarity and distinctness we’re looking for as critical thinkers, and the careful definition of
terms is one of our most useful tools in pursuing this goal. While the business of definitions may seem
straightforward (“‘carrot’ refers to a tapering, orange-colored root eaten as a vegetable”), you’ll soon see that there’s
more to it than you might have thought. For example, a multitude of attempts have been made to construct a
definition of “person” (or, if you like, “human being”). Everything from “rational animal” to “featherless biped” has
been suggested. But such important issues as whether abortion is morally permissible, whether fetuses have rights,
whether a fetus is correctly referred to as an “unborn child,” and doubtless many others—all turn on how we define
“person” and some of these other basic concepts. Indeed, if we define “abortion” as “the murder of an unborn
child,” the debate on abortion is over before it begins.
A definition is the start of an argument, not the end of one.
—NEIL POSTMAN, author of Amusing Ourselves to Death: Public Discourse in the Age of Show Business
Page 84
2/9/2016 12:17 PM
Some arguments against the acceptance of rights for homosexuals depend on the claim that their
orientation is “unnatural.” * But to arrive at a definition of “natural” (or “unnatural”) is no easy task. If
you spend a few minutes thinking about this difficulty—even better, if you discuss it with others—we
think you’ll see what we mean. What is “natural,” depending on who is defining the term, can mean
anything from “occurs in nature” to “correct in the eyes of God.”
The definition of the word “use” by the U.S. Supreme Court made a difference of thirty years in the
sentence of John Angus Smith in a criminal case a few years ago.** We hope you are convinced of the
importance of the subject. Now, let’s have a look at how to deal with definitions.
Purposes of Definitions
We’ll start by indicating some of the purposes that definitions serve, then go on to describe several
different types of definitions. After that, we’ll give some rough and ready ideas on giving good
definitions.
Definitions can serve several purposes, but we want to call your attention to four.
1. The first and main purpose served by definitions is to tell us what a word means. When we don’t
know a word’s meaning, we often look it up in a dictionary. The definitions given there are lexical
definitions; they tell us what the word ordinarily means (“tamarin. noun: a small, forest-dwelling
South American monkey of the marmoset family, typically brightly colored and with tufts and crests of
hair around the face and neck.”). You might well ask, Isn’t this what all definitions do? A good question,
and the answer is no. Check these next two items.
2. Sometimes a word needs to take on a special meaning in a given context. For this, we need a
stipulative definition. An example: “In this environment, ‘desktop’ means the basic opening screen of
the operating system—the one with the trash can.” We also assign stipulative definitions to words we
invent. Stephen Colbert invented the word “truthiness” on his inaugural Colbert Report in 2005. Its
assigned meaning (its stipulative definition) can be stated as “[the quality possessed by] those things a
person claims to know intuitively or ‘from the gut’ without regard to evidence, logic, intellectual
examination, or facts.Ӡ
3. A third important purpose of definitions is to reduce vagueness or generality or to eliminate
ambiguity. “In this contract, the word ‘dollars’ will refer only to Canadian dollars, even if one party
normally deals in U.S. dollars or Australian dollars.” Definitions that serve this purpose are said to be
precising definitions.

4. Finally, definitions can be used to persuade. These troublesome items are known as persuasive
or rhetorical definitions. It isn’t clear that we should think of them as real definitions, since they are
not intended to provide either ordinary or agreed-upon meanings for terms. Nonetheless, they are often
listed with the others we’ve mentioned. But be warned, these “definitions” are designed to influence
beliefs or attitudes, not simply to convey linguistic information. If a liberal friend tries to “define” a
conservative as “a hidebound, narrow-minded hypocrite who thinks the point to life is making money
and ripping off poor people,” you know the point here is not the clarification of the meaning of the word
“conservative.” It is a way of trashing conservatives. Such rhetorical definitions frequently make use of
the emotive meaning (or, if you prefer, the rhetorical force) of words. This meaning consists of the
positive or negative associations of a word. Consider the difference between “government-guaranteed
health care” and a “government takeover of health care.” These terms might reasonably be used to refer
to the same thing, but they clearly have different emotional associations—one positive and one negative.
The word “connotation” is the traditional term for these associations.
It’s bad poetry executed by people who can’t sing. That’s my definition of Rap.
—PETER STEELE
We’re guessing he doesn’t like it.
Our definition of “abortion” as “the murder of an unborn child” at the beginning of this section is
another much-quoted example of this type of definition. *
Kinds of Definitions
We’ve looked at some important purposes to which definitions can be put, and we must now distinguish
between those purposes and the types of definitions that are used to serve them. Remember that the
purpose of a definition and the type of definition it is are different things. (Compare: The purpose of
food is to nourish our bodies and please our palettes, whereas types of food are vegetables, meat,
Pringles, etc.)
Regardless of what purpose is served by defining a term, most definitions are of one of the three
following types:
1.
Definition by example (also called ostensive definition): Pointing to, naming, or otherwise
identifying one or more examples of the sort of thing to which the term applies: “By ‘scripture,’ I
mean writings like the Bible and the Koran.” “A mouse is this thing here, the one with the
buttons.”
2.
Definition by synonym: Giving another word or phrase that means the same as the term being
defined. “‘Fastidious’ means the same as ‘fussy.’” “‘Pulsatile’ means ‘throbbing.’” “To be
‘lubricious’ is the same as to be ‘slippery.’”
3.
Analytical definition: Specifying the features that a thing must possess in order for the term being
defined to apply to it. These definitions often take the form of a genus-and-species classification.
For example, “A samovar is an urn that has a spigot and is used especially in Russia to boil water
for tea.” “A mongoose is a ferret-sized mammal native to India that eats snakes and is related to
civets.”
Almost all dictionary definitions are of the analytical variety.

Some Tips on Definitions
So far, we’ve seen that definitions serve a variety of purposes and take several different forms.
Combinations can be of many sorts: a definition by synonym that is precising (“minor” means under
eighteen); an analytical definition designed just to persuade (a liberal is somebody who wants the able
and willing to take care of both the unable and the unwilling). But what makes a definition a good one?
First, definitions should not prejudice the case against one side of a debate or the other. This is one
form of begging the question, which will be discussed in some detail in Chapter 7. For now, just recall
that one cannot usually win a debate simply by insisting on one’s own favored definition of key terms,
since those who disagree with your position will also disagree with your definitions. Definitions are
instances in which people have to try to achieve a kind of neutral ground.
Second, definitions should be clear. They are designed to clear the air, not muddy the water. This
means they should be expressed in language that is as clear and simple as the subject will allow. If we
define a word in language that is more obscure than the original word, we accomplish nothing. This
includes avoiding emotively charged language whenever possible.
Realize that sometimes you must get along with incomplete definitions. In real life, we sometimes
have to deal with claims that include such big-league abstractions as friendship, loyalty, fair play,
freedom, rights, and so forth. If you have to give a complete definition of “freedom” or “fair play,”
you’d best not plan on getting home early. Such concepts have subtle and complex parameters that
might take a lifetime to pin down. For practical purposes, what is usually needed for words like these is
not a complete definition but a precising definition that focuses on one aspect of the concept and
provides sufficient guidance for the purposes at hand: “To me, the word ‘justice’ does not include
referring to a person’s private life when evaluating his or her work performance.”
In Depth
Are We Innately Selfish?
You sometimes hear beginning students in philosophy maintaining that every voluntary action
is a selfish one, done only to benefit oneself. This is a striking idea, and the student typically is
quite impressed by the finding. The argument for the idea normally proceeds something like
this: All voluntary acts are done to satisfy one’s own desire to do them; thus, all voluntary acts
are done for self-benefit; thus, all voluntary acts are selfish acts.*
The problem, if it isn’t obvious, is that this argument does not make use of our ordinary
notion of selfishness. Ordinarily, if we’re told that someone is a selfish person, we think we’ve
learned something important about them, not simply that they perform voluntary actions. This
indicates that the argument above makes use of a new and different meaning for “selfish.” If
we had only the new meaning for the word, we’d probably stop using it, since it conveys
nothing interesting about a person.
The key to spotting mistakes like this is to have a clear definition of key terms and to
keep it in mind throughout the discussion.
*A diagram for this simple argument is provided in the answer section, p. 509.

The following exercise will give you practice with definitions.
Exercise 3-3
In groups (or individually if your instructor prefers), determine what term in each of the
following is being defined and whether the definition is by example or by synonym or an
analytical definition. If it is difficult to tell which kind of definition is present, describe
the difficulty.
1.
A piano is a stringed instrument in which felt hammers are made to strike the strings
by an arrangement of keys and levers.
2.
“Decaffeinated” means without caffeine.
3.
Steve Martin is my idea of a successful philosophy major.
4.
The red planet is Mars.
5. “UV” refers to ultraviolet light.
6. The Cheyenne perfectly illustrate the sort of Native Americans who were Plains
Indians.
7.
Data, in our case, is raw information collected from survey forms, which is then put
in tabular form and analyzed.
8.
“Chiaroscuro” is just a fancy word for shading.
9. Bifocals are glasses with two different prescriptions ground into each lens, making
it possible to focus at two different distances from the wearer.
10. Red is the color that we perceive when our eyes are struck by light waves of
approximately seven angstroms.
11.
A significant other can be taken to be a person’s spouse, lover, long-term
companion, or just girlfriend or boyfriend.
12. “Assessment” means evaluation.
13. A blackout is “a period of total memory loss, as one induced by an accident or
prolonged alcoholic drinking.” When your buddies tell you they loved your
rendition of the Lambada on Madison’s pool table the other night and you don’t
even remember being at Madison’s, that is a blackout.
—Adapted from the CalPoly, San Luis Obispo, Mustang Daily
14. A pearl, which is the only animal-produced gem, begins as an irritant inside an
oyster. The oyster then secretes a coating of nacre around the irritating object. The
result is a pearl, the size of which is determined by the number of layers with which
the oyster coats the object.
15. According to my cousin, who lives in Tulsa, the phrase “bored person” refers to
anybody who is between the ages of sixteen and twenty-five and lives in eastern
Oklahoma.

WRITING ARGUMENTATIVE ESSAYS
Recently, the Educational Testing Service revamped the infamous Scholastic Aptitude Test (SAT), which
many universities use when determining whether to admit an applicant. The most significant change was
to have test takers write an argumentative essay. This change in the SAT shows the importance the
educators place on the ability to write this type of essay. That’s because writing an argumentative essay
is doing nothing other than thinking critically—and leaving a paper trail for others to follow. This isn’t a
book on writing, but writing an argumentative essay is so closely related to thinking critically that we
would like to take the opportunity to offer our recommendations. We know professors who have retired
because they could not bear to read another student essay. As a result, we offer our two bits’ worth here
in hopes of continuing to see familiar faces.

As we said back on p. 71, an argumentative essay generally has four components:
1. A statement of the issue
2. A statement of one’s position on that issue
3. Arguments that support one’s position
4. Rebuttals of arguments that support contrary positions
Ideally, your essay should begin with an introduction to the issue that demonstrates that the issue is
important or interesting. This is not always easy, but even when you are not excited about the subject
yourself, it is still good practice to try to make your reader interested. Your statement of the issue should
be fair; that is, don’t try to state the issue in such a way that your position on it is obviously the only
correct one. This can make your reader suspicious; the burden of convincing him or her will come later,
when you give your arguments.
Your position on the issue should be clear. Try to be brief. If you have stated the issue clearly, it
should be a simple matter to identify your position.
Your arguments in support of your position also should be as succinct as you can make them, but it
is much more important to be clear than to be brief. After all, this is the heart of your essay. The reasons
you cite should be clearly relevant, and they should be either clearly reliable or backed up by further
arguments. Much of the rest of this book is devoted to how this is done; hang in there.
If there are well-known arguments for the other side of the issue, you should acknowledge them
and offer some reason to believe that they are unconvincing. You can do this either by attacking the
premises that are commonly given or by trying to show that those premises do not actually support the
opposing conclusion. More on these topics later, too.
Following are some more detailed hints that might be helpful in planning and writing your
argumentative essay.
1. Focus. Make clear at the outset what issue you intend to address and what your position on the
issue will be. However, nothing is quite so boring as starting off with the words “In this essay, I shall
argue that X, Y, and Z,” and then going on to itemize everything you are about to say, and at the end
concluding with the words “In this essay, I argued that X, Y, and Z.” As a matter of style, you should let
the reader know what to expect without using trite phrases and without going on at length. However, you
should try to find an engaging way to state your position. For example, instead of “In this essay, I shall
discuss the rights of animals to inherit property from their masters,” you might begin, “Could your
inheritance wind up belonging to your mother’s cat?”

2. Stick to the issue. All points you make in an essay should be connected to the issue under
discussion and should always either (a) support, illustrate, explain, clarify, elaborate on, or emphasize
your position on the issue, or (b) serve as responses to anticipated objections. Rid the essay of
irrelevancies and dangling thoughts.
3. Arrange the components of the essay in a logical sequence. This is just common sense. Make a
point before you clarify it, for example, not the other way around.
When supporting your points, bring in examples, clarification, and the like in such a way that a
reader knows what in the world you are doing. A reader should be able to discern the relationship
between any given sentence and your ultimate objective, and he or she should be able to move from
sentence to sentence and from paragraph to paragraph without getting lost or confused. If a reader
cannot outline your essay with ease, you have not properly sequenced your material. Your essay might
be fine as a piece of French philosophy, but it would not pass as an argumentative essay.
4. Be complete. Accomplish what you set out to accomplish, support your position adequately, and
anticipate and respond to possible objections. Keep in mind that many issues are too large to be treated
exhaustively in a single essay. The key to being complete is to define the issue sharply enough that you
can be complete. Thus, the more limited your topic, the easier it is to be complete in covering it.
Also, be sure there is closure at every level. Sentences should be complete, paragraphs should be
unified as wholes (and usually each should stick to a single point), and the essay should reach a
conclusion. Incidentally, reaching a conclusion and summarizing are not the same thing. Short essays do
not require summaries.
Good Writing Practices
Understanding the four principles just mentioned is one thing, but actually employing them may be more
difficult. Fortunately, there are five practices that a writer can follow to improve the organization of an
essay and to help avoid other problems. We offer the following merely as a set of recommendations
within the broader scope of thinking critically in writing.
I’m for abolishing and doing away with redundancy.
—J. CURTIS MCKAY, of the Wisconsin State Elections Board (reported by Ross and Petras)
We ourselves are also for that too.
1. At some stage after the first draft, outline what you have written. Then, make certain the outline is
logical and that every sentence in the essay fits into the outline as it should. Some writers create an
informal outline before they begin, but many do not. Our advice: Just identify the issue and your
position on it, and start writing by stating them both.
2. Revise your work. Revising is the secret to good writing. Even major-league writers revise what
they write, and they revise continuously. Unless you are more gifted than the very best professional
writers, revise, revise, revise. Don’t think in terms of two or three drafts. Think in terms of
innumerable drafts.
Page 90

3. Have someone else read your essay and offer criticisms of it. Revise as required.
4. If you have trouble with grammar or punctuation, reading your essay out loud may help you detect
problems your eyes have missed.
5. After you are completely satisfied with the essay, put it aside. Then, come back to it later for still
further revisions.
Essay Types to Avoid
Seasoned instructors know that the first batch of essays they get from a class will include samples of
each of the following types. We recommend avoiding these mistakes:
The Windy Preamble. Writers of this type of essay avoid getting to the issue and instead go on at
length with introductory remarks, often about how important the issue is, how it has troubled
thinkers for centuries, how opinions on the issue are many and various, and so on, and so on.
Anything you write that smacks of “When in the course of human events …” should go into the trash
can immediately.
On Language
And While We’re on the Subject of Writing
Don’t forget these rules of good style:
1. Avoid clichés like the plague.
2. Be more or less specific.
3. NEVER generalize.
4. The passive voice is to be ignored.
5. Never, ever be redundant.
6. Exaggeration is a billion times worse than understatement.
7. Make sure verbs agrees with their subjects.
8. Why use rhetorical questions?
9. Parenthetical remarks (however relevant) are (usually) unnecessary.
10. Proofread carefully to see if you any words out.
11.
And it’s usually a bad idea to start a sentence with a conjunction.
This list has been making the rounds on the Internet.

The Stream-of-Consciousness Ramble. This type of essay results when writers make no attempt to
organize their thoughts and simply spew them out in the order in which they come to mind.
The Knee-Jerk Reaction. In this type of essay, writers record their first reaction to an issue without
considering the issue in any depth or detail. It always shows.
The Glancing Blow. In this type of essay, writers address an issue obliquely. If they are supposed to
evaluate the health benefits of bicycling, they will bury the topic in an essay on the history of
cycling; if they are supposed to address the history of cycling, they will talk about the benefits of
riding bicycles throughout history.
Let the Reader Do the Work. Writers of this type of essay expect the reader to follow them through
non sequiturs, abrupt shifts in direction, and irrelevant sidetracks.
Persuasive Writing
The primary aim of argumentation and the argumentative essay is to support a position on an issue.
Good writers, however, write for an audience and hope their audience will find what they write
persuasive. If you are writing for an audience of people who think critically, it is helpful to adhere to
these principles:
1. Confine your discussion of an opponent’s point of view to issues rather than personal
considerations.
2. When rebutting an opposing viewpoint, avoid being strident or insulting. Don’t call opposing
arguments absurd or ridiculous.
3. If an opponent’s argument is good, concede that it is good.
4. If space or time is limited, be sure to concentrate on the most important considerations. Don’t
become obsessive about refuting every last criticism of your position.
5. Present your strongest arguments first.
There is nothing wrong with trying to make a persuasive case for your position. However, in this
book, we place more emphasis on making and recognizing good arguments than on simply devising
effective techniques of persuasion. Some people can be persuaded by poor arguments and doubtful
claims, and an argumentative essay can be effective as a piece of propaganda even when it is a rational
and critical failure. One of the most difficult things you are called upon to do as a critical thinker is to
construct and evaluate claims and arguments independently of their power to win a following. The
remainder of this book—after a section on writing and diversity—is devoted to this task.
Writing in a Diverse Society
In closing, it seems appropriate to mention how important it is to avoid writing in a manner that
reinforces questionable assumptions and attitudes about people’s gender, ethnic background, religion,
sexual orientation, physical ability or disability, or other characteristics. This isn’t just a matter of ethics;
it is a matter of clarity and good sense. Careless word choices relative to such characteristics not only
are imprecise and inaccurate but also may be viewed as biased even if they were not intended to be, and
thus they may diminish the writer’s credibility. Worse, using sexist or racist language may distort the
writer’s own perspective and keep him or her from viewing social issues clearly and objectively.
Page 92
2/9/2016 12:17 PM
But language isn’t entirely not a matter of ethics, either. We are a society that aspires to be just, a
society that strives not to withhold its benefits from individuals on the basis of their ethnic or racial
background, skin color, religion, gender, or disability. As a people, we try to end practices and change or
remove institutions that are unjustly discriminatory. Some of these unfair practices and institutions are,
unfortunately, embedded in our language.
“Always” and “never” are two words you should always remember never to use.
—WENDELL JOHNSON
Another tip on writing.
Some common ways of speaking and writing, for example, assume that “normal” people are all
white males. It is still not uncommon, for instance, to mention a person’s race, gender, or ethnic
background if the person is not a white male, and not to do so if the person is. Of course, it may be
relevant to whatever you are writing about to state that this particular individual is a male of Irish
descent, or whatever; if so, there is absolutely nothing wrong with saying so.
What day is the day after three days before the day after tomorrow?
Complicated, but neither vague nor ambiguous.
Some language practices are particularly unfair to women. Imagine a conversation among three
people, you being one of them. Imagine that the other two talk only to each other. When you speak, they
listen politely; but when you are finished, they continue as though you had never spoken. Even though
what you say is true and relevant to the discussion, the other two proceed as though you were invisible.
Because you are not being taken seriously, you are at a considerable disadvantage. You have reason to
be unhappy.
In an analogous way, women have been far less visible in language than men and have thus been at
a disadvantage. Another word for the human race is not “woman,” but “man” or “mankind.” The generic
human has often been referred to as “he.” How do you run a project? You man it. Who supervises the
department or runs the meeting? The chairman. Who heads the crew? The fore man. Picture a research
scientist to yourself. Got the picture? Is it a picture of a woman? No? That’s because the standard
picture, or stereotype, of a research scientist is a picture of a man. Or, read this sentence: “Research
scientists often put their work before their personal lives and neglect their husbands.” Were you
surprised by the last word? Again, the stereotypical picture of a research scientist is a picture of a man.
A careful and precise writer finds little need to converse in the lazy language of stereotypes,
especially those that perpetuate prejudice. As long as the idea prevails that the “normal” research
scientist is a man, women who are or who wish to become research scientists will tend to be thought of
as out of place. So they must carry an extra burden, the burden of showing that they are not out of place.
That’s unfair. If you unthinkingly always write, “The research scientist … he,” you are perpetuating an
image that places women at a disadvantage. Some research scientists are men, and some are women. If
you wish to make a claim about male research scientists, do so. But if you wish to make a claim about
research scientists in general, don’t write as though they were all males.

The rule to follow in all cases is this: Keep your writing free of irrelevant implied evaluation of
gender, race, ethnic background, religion, or any other human attribute.
Recap
This list summarizes the topics covered in this chapter:
Clarity of language is extremely important to the ability to think critically.
Clarity of language can often be lost as a result of multiple causes, including,
importantly, vagueness, ambiguity, and generality.
Vagueness is a matter of degree; what matters is not being too vague for the purposes
at hand.
A statement is ambiguous when it is subject to more than one interpretation and it
isn’t clear which interpretation is the correct one.
Some main types of ambiguity are semantic ambiguity, syntactic ambiguity, grouping
ambiguity, and ambiguous pronoun reference.
A claim is overly general when it lacks sufficient detail to restrict its application to
the immediate subject.
To reduce vagueness or eliminate ambiguity, or when new or unfamiliar words are
brought into play, or familiar words are used in an unusual way, definitions are our
best tool.
The most common types of definitions are definition by synonym, definition by
example, and analytical definition.
Some “definitions” are intended not to clarify meaning but to express or influence
attitude. These are known as rhetorical definitions.
Rhetorical definitions accomplish their ends by means of the rhetorical force (emotive
meaning) of terms.
Critical thinking done on paper is known as an argumentative essay, a type of writing
worth mastering, perhaps by following our suggestions.

A rough draft is due before Thanksgiving. The final version is due at the end
of the semester.
Exercise 3-6
Read the following passage, paying particular attention to the italicized words and
phrases. All of these expressions would be too imprecise for use in some contexts;
determine which are and which are not too imprecise in this context.
In view of what can happen in twelve months to the fertilizer you apply at any
one time, you can see why just one annual application may not be adequate.
Here is a guide to timing the feeding of some of the more common types of
garden flowers.
Feed begonias and fuchsias frequently with label-recommended amounts or
less frequently with no more than half the recommended amount. Feed roses
with label-recommended amounts as a new year’s growth begins and as each
bloom period ends. Feed azaleas, camellias, rhododendrons, and similar plants
immediately after bloom and again when the nights begin cooling off.
Following these simple instructions can help your flower garden to be as
attractive as it can be.
Exercise 3-7
Rewrite the following claims to remedy problems of ambiguity. Do not assume that
2/9/2016 12:17 PM

common sense by itself solves the problem. If the ambiguity is intentional, note this fact,
and do not rewrite.

Example
Former professional football player Jim Brown was accused of assaulting a
thirty-three-year-old woman with a female accomplice.
Answer
This claim is syntactically ambiguous because it isn’t clear what the phrase
“with a female accomplice” modifies—Brown, the woman who was attacked,
or, however bizarre it might be, the attack itself (he might have thrown the
accomplice at the woman). To make it clear that Brown had the accomplice, the
phrase “with a female accomplice” should have come right after the word
“Brown” in the original claim.

friend whom he has not seen in years walking in his direction with a little girl. They greet
each other warmly, and the friend says, “I married since I last saw you, to someone you
never met, and this is my daughter, Ellen.” The man says to Ellen, “You look just like

Classroom/Writing Exercise
This exercise is designed for use in the classroom, although your instructor may make a
different kind of assignment. Consider the often heard claim, “Homosexuality is not
natural.” Many people agree or disagree with this statement even though they have only
the most rudimentary idea of what it might mean. Discuss what you think might be meant
by the claim, taking note of any vagueness or ambiguity that might be involved.
Writing Exercises
Everyone, no matter how well he or she writes, can improve. And the best way to
improve is to practice. Since finding a topic to write about is often the hardest part of a
writing assignment, we’re supplying three subjects for you to write about. For each—or
whichever your instructor might assign—write a one- to two-page essay in which you
clearly identify the issue (or issues), state your position on the issue (a hypothetical
position if you don’t have one), and give at least one good reason in support of your
position. Try also to give at least one reason why the opposing position is wrong.
1. The exchange of dirty hypodermic needles for clean ones, or the sale of clean ones,
is legal in many states. In such states, the transmission of HIV and hepatitis from
dirty needles is down dramatically. But bills [in the California legislature] to

legalize clean-needle exchanges have been stymied by the last two governors, who
earnestly but incorrectly believed that the availability of clean needles would
increase drug abuse. Our state, like every other state that has not yet done it, should
immediately approve legislation to make clean needles available.

2. On February 11, 2003, the Eighth Circuit Court of Appeals ruled that the state of
Arkansas could force death-row prisoner Charles Laverne Singleton to take
antipsychotic drugs to make him sane enough to execute. Singleton was to be
executed for felony capital murder but became insane while in prison. “Medicine is
supposed to heal people, not prepare them for execution. A law that asks doctors to
make people well so that the government can kill them is an absurd law,” said
David Kaczynski, the executive director of New Yorkers Against the Death Penalty.
3.
Some politicians make a lot of noise about how Canadians and others pay much less
for prescription drugs than Americans do. Those who are constantly pointing to the
prices and the practices of other nations when it comes to pharmaceutical drugs
ignore the fact that those other nations lag far behind the United States when it
comes to creating new medicines. Canada, Germany, and other countries get the
benefits of American research but contribute much less than the United States does
to the creation of drugs. On the surface, these countries have a good deal, but in
reality everyone is worse off, because the development of new medicines is slower
than it would be if worldwide prices were high enough to cover research costs.
