Chapter 16 details on speech to persuade
What modern scholars of persuasion
refer to as credibility, Aristotle referred to as ethos . According to your textbook, the two most
important factors affecting the credibility of a persuasive speaker are competence and character . Above all, a your credibility is affected by these two
factors: competence and character .
Initial credibility describes your
credibility before you begin to speak; in the persuasive speech listeners will
recall your previous displays of credibility— or not. Derived credibility is the credibility produced by
everything you say and do during the speech. Your terminal credibility describes your
credibility status at the end of your speech. Use Logos (the
name used by Aristotle for the logical appeal of a speaker) and Pathos
(
the name used by Aristotle for the emotional appeal of a speaker) throughout — you are appealing to our hearts
and minds, figuratively speaking.
When used in any speech, supporting
materials such as examples, statistics, and testimony are referred to as evidence . Your textbook presents four tips
for using evidence in a persuasive speech.
They
are as follows:
a. Use
specific evidence
b. Use novel evidence.
c. Use
evidence from credible sources.
d. Make
clear the point of your evidence.
Reasoning is a process of drawing a
conclusion based on evidence. According
to your textbook, the following statement is an example of causal reasoning that hedges the claim and
narrowly avoids what type of logical fallacy?
President John Kennedy was assassinated on November 22, 1963. The
Beatles hit the top of the charts for the first time less than a month later.
Can there be any doubt that the BeatlesÕ rise
to popularity was brought about partly by KennedyÕs death, which left a void in the hearts of AmericaÕs youth that was quickly filled by the dynamic
singing group?
According to your textbook, the following statement is an example
of the slippery
slope fallacy: You will be sorry if you allow employees to take time off to
aid sick family members. First they will want time off to help spouses and
children. Then they will skip work to help parents and grandparents. Before you
know it, they will be gone for nephews and cousins, and you wonÕt have anyone around to do their jobs.
According to your textbook, the
following statement is an example of analogical reasoning :School administrators in Long
Beach, California, report that school uniforms have reduced school crime by 36
percent, increased attendance by 22 percent, and decreased student suspensions
by 32 percent. If such a policy works in Long Beach, it can work in our school
district.
According to your textbook, the
following statement is an example of the
red
herring fallacy: I donÕt know why we are wasting time debating campaign finance reform
when more and more international terrorists are focusing
their attacks on the United
States.
According to your textbook, the
following statement is an example of reasoning from specific
instances . In Montana an infantÕs
under active thyroid went undiagnosed for three months because of a medical
laboratory testing error. In Louisiana a 26-year-old woman died because a
medical laboratory inaccurately analyzed a mole that had been removed from her
neck as non cancerous. And in California a teacher lost his life to a rare form
of pneumonia when a medical laboratory confused his test results with those of
another person. We can see, then, that inaccurate medical lab tests are a
problem throughout the US.
According to your textbook, the
following statement is an example of the
either-or fallacy: Our company has only two options—either to cut employee benefits or
to lay off large numbers of workers.
According to your textbook, the
following statement is an example of the
bandwagon fallacy: I think the governor has excellent ideas for prison
reform. After all, polls show that 70 percent of the state supports his
position.
Your textbook discusses three methods
of generating emotional appeal in a persuasive speech. The three methods are as
follows:
a. Use
emotional language.
b. Develop
vivid examples.
c. Speak
with sincerity and conviction.
