In a good argument (such as the one that appears to be going on in the above cartoon), the other person listens carefully as we state our case, waiting to see if we really have solid evidence to support our point of view.

CHAPTER 9 Argument

Argumentation is a part of our everyday dealings with other people. It is also an important part of much of what we read. Authors often try to convince us of their opinions and interpretations.

CHAPTER 9 Argument

Very often the most important things we must do as critical readers are

Recognize the point the author is making.

Decide if the author’s support is relevant.

3 Decide if the author’s support is adequate.

A Good Argument

A good argument is one in which you make a point and then provide persuasive and logical evidence to back it up.

CHAPTER 9 Argument

Point: The Beef and Burger Shop is a poor fast-food restaurant.

This statement hardly discourages us from visiting the Beef and Burger Shop.

But suppose the it is followed by these reasons:

Here is a point.


CHAPTER 9 Argument

Point: The Beef and Burger Shop is a poor fast-food restaurant.


The burgers are full of gristle.

The roast beef sandwiches have a chemical taste.

3 The fries are lukewarm and soggy.

Clearly, these details provide solid support for the point. In light of these details, our mouths are not watering for lunch at the Beef and Burger Shop.

CHAPTER 9 Argument


Clear thinking in an argument means: making a point and providing support that truly backs up that point.

A valid argument may also be described as a conclusion supported by logical reasons, facts, examples, and other evidence.

CHAPTER 9 Argument


Point: There are certain creatures in particular that you would never want to bite you.

Here is another example.

A bite from the venomous king cobra can cause muscle paralysis and lead to respiratory failure in a matter of minutes.A lion’s bite is powerful enough to rip off your arm or take large chunks out of your body.

3 A crocodile’s jaws will snap closed like a steel trap, and if the crocodile then decides to roll, you can usually say goodbye to your arm, leg, or whatever is in its mouth.

With such solid support, you’re likely to agree that the king cobra, lion, and crocodile are especially scary biters and that a logical point has been made.

Valid Argument

To evaluate an argument . . .

. . . you need to recognize its point and support.

CHAPTER 9 Argument

The Basics of Argument: Point and Support / The Point and Supprt of an Argument

To see if a sentence is a statement of support, try inserting the word because in front of it. If the statement sounds right, it is probably a statement of support.

For example, we could say, “Because the burgers are full of gristle, because the roast beef sandwiches have a chemical taste, and because the fries are lukewarm and soggy, I’ve come to the conclusion that the Beef and Burger Shop is a poor fast-food restaurant.”

Noise, roaches, and an unresponsive landlord are three reasons that support the point—that it’s time to look for another apartment.

CHAPTER 9 Argument

Relevant Support

RelevantSupport

Support that really applies to

the pointis

Once you identify the point and support of an argument, you need to decide if each piece of evidence is relevant—in other words, if it really applies to the point.

CHAPTER 9 Argument

Point: You should lend me money this week.

Support: You didn’t lend me money last week when I needed it.

Problem: Last week is beside the point; the question is whether or not you should lend him money this week.

Not Relevant

In their enthusiasm for making an argument, people often bring up irrelevant support. For example, trying to persuade you to lend him some money this week, a friend might say, “You didn’t lend me money last week when I needed it.”

Relevant Support

CHAPTER 9 Argument

Relevant Support

Point: My dog Otis is not very bright.

A. He cries when I leave for work every day.

B. He’s five years old and doesn’t respond to his name yet.

Which of the statements below is relevant support for this point about Otis not being very bright?

CHAPTER 9 Argument

Relevant Support




Most dogs know their names, so Otis’s unfamiliarity with his own name reveals a weak memory, and memory is one aspect of intelligence.

CHAPTER 9 Argument

Relevant Support




Not Relevant

Even an intelligent dog might be sad when its companions leave the house.

CHAPTER 9 Argument

Relevant Support


C. He often attacks the backyard hedge as if it’s a hostile animal.

D. He always gets excited when visitors arrive.

Which of the statements below is relevant support for this point about Otis not being very bright?

CHAPTER 9 Argument

Relevant Support




The inability to distinguish between a bush and an animal—friendly or hostile—suggests a lack of analytical skills.

CHAPTER 9 Argument

Relevant Support




Not Relevant

Both bright and not-so-bright dogs are happy to see old and new human friends.

CHAPTER 9 Argument

Adequate Support

AdequateSupport

Support substantial enough to prove

the pointis

A valid argument must include not only relevant support but also an adequate amount of support—enough to prove the point

CHAPTER 9 Argument

Adequate Support

Point: Abortion is wrong.

Support: My sister had an abortion and has regretted it ever since.

Not Adequate

It would not be valid to argue “Abortion is wrong” if this were one’s only support. Such an important issue would require more support than the attitude and experience of a single relative.

CHAPTER 9 Argument

Adequate Support

Support:The first time I went to that beach, I got a bad case of sunburn.

The second time I went to that beach, I couldn’t go in the water because of the pollution.

The third time I went to that beach, I stepped on a starfish and had to go to the emergency room to have the spikes removed from my foot.

Read these three supporting reasons.

CHAPTER 9 Argument

Adequate Support




That beach is unsafe and should be closed.

I’ve had a string of bad experiences at that beach.

Beaches are not safe places.

A.

B.

C.

Which point do the above reasons adequately support?

We’re never going to get this planet cleaned up.D.

CHAPTER 9 Argument

Adequate Support







A.

B.

C.



Answer A is not adequately supported by three isolated instances; we’d need many more reports of dangerous conditions before considering having the beach closed.

Not Adequately Supported

CHAPTER 9 Argument

Adequate Support







A.

B.

C.



Answer C is even more poorly supported. We’d need many, many reports of dangerous conditions at beaches worldwide to come to this conclusion.



CHAPTER 9 Argument

Adequate Support







A.

B.

C.



Answer D is supported in part by the reference to pollution in the second statement of support, but the statements about sunburn and the starfish are not examples of pollution.

CHAPTER 9 Argument

Answer B is adequately supported by the three statements. They describe three bad experiences the speaker had at a particular beach.
