4. Reading with Your Eyes and Your Brain
Skillful readers learn how to read persuasive or
opinionated text with a very critical eye. They
realize that the author’s purpose is to convince the
reader to believe what the author is saying and to
consider the arguments given as valid even if they
violate logical reasoning and lack supporting
evidence. The author’s motive may be to get the
reader to buy something, vote a certain way,
change an attitude, or behave differently.
5. • In order to avoid manipulation by the author,
good readers learn how to detect poor
reasoning and faulty arguments. They are
able to identify the various logical fallacies
such as begging the question, strawman,
overgeneralization, slippery slope, and
others. During this lesson, we will study
logical fallacies.
6. In order for an argument to present a strong,
logical position, specific evidence and
examples need to be provided.
7. Some authors use personal attacks on their
opponent in order to divert attention away
from issues that really matter.
8. The Personal Attack Fallacy
An Ad Hominem is a general category of fallacies in
which a claim or argument is rejected on the basis of
some irrelevant fact about the person presenting the
claim or argument. Typically, this fallacy involves two
steps. First, the character of the person making the
claim is attacked. Second, this attack is taken to be
evidence against the argument or claim the person in
question is making.
9. Aggression and personal attacks
are sometimes used to discredit
an opponents position on an issue.
10. How Does the Ad Hominem Fallacy Work?
A DOCTOR tells her patient to lose weight, and the
patient thinks: “If my doctor really believed that,
she wouldn’t be so fat.” A movie aficionado pans
the latest Tom Cruise flick because Cruise is a
Scientologist. A homeowner ignores a neighbor’s
advice on lawn care because the neighbor is a ...
you name it: Democrat, Republican, Christian or
atheist. These examples illustrate classic uses of
ad hominem attacks, in which an argument is
rejected, or advanced, based on a personal
characteristic of an individual rather than on
reasons for or against the claim itself.
11. Let’s Take a Closer Look
Putting the focus on the arguer or person being
discussed can distract us from the issues that
matter. Rather than concentrating on an
individual’s character, we should, in these
cases, be asking ourselves questions such as,
Is the doctor’s advice medically sound? Is the
Cruise film entertaining? Is the neighbor’s lawn
healthy? After all, determining the facts and
evidence that leads us to the truth is what
should matter.
13. The Strategy of Personal Attack
Attack the person in some way.
For example:
• Attack their expertise, questioning their qualifications
or experience
• Criticize their physical appearance or dress
• Comment on their inability to make a good argument
• Point out their junior or lower status
• Attack their values as being contrary to social norms
• Attack those who support them or agree with them
16. How could you possibly know
anything about this issue???
Use of marital status to invalidate an
opinion of someone of a different status,
e.g., “How can you make a decision
about someone having marital problems
if you’ve never been married yourself?”
Using gender as a means to devalue an
argument from an opposing gender, e.g.,
“This is a female issue. As a man, how
can you have an opinion about this?”
