6Building A Persuasive Speech
7Moving from analysis to proof
8Aristotle Greek teacher/scientist (384-322 B.C.)
- Student of Plato
- Teacher of Alexander the Great
- Author of over 170 works 30 of which survive
- His work, the Rhetoric, is widely regarded as the
most important work on persuasion ever published.
9Aristotle asked how do we come to believe
something or to believe we should act in a
certain way in the absence of knowing the truth?
- Ethos--ethical, credibility appeal
- Pathos--pathetic, emotional appeal
- Logos--logical, rational appeal
10Ethos
11Pathos
12Logos
13Three Types of Support Material
- Examples
- Statistics
- Testimony
14- Best when ethos, logos and pathos all work
together. - Easiest way to accomplish this?
- Include testimony and statistics and examples as
you build your case.
15Logos, Ethos and Pathos in the Bone Marrow Speech
- The statistics and other evidence in the problem
section help ground the logos/rational appeal of
the speech. - The fact that she is part of the registry, her
experience in the process of donating and her
evident research build the ethos/credibility
appeal. - The stories of need, the simplicity of the
process, the examples of lives saved, and the
you can make a difference appeal establish the
pathos/emotional energy of the speech.
16Logos, Ethos and Pathos in the Driving Age Speech
- Structure and evidence give a strong
logos/rational appeal. - Personal connection to tragedy, confidence in
delivery, adapting to audience give a strong
ethos/credibility appeal. - Personal story, translated numbers, intense
conclusion give a clear pathos/emotional appeal.
17The Building Blocks
- Strong Analysis Problem, Plan, Practicality
- Evidence / Supporting Material using Ethos, Logos
and Pathos - Statistics, Examples, Testimony
- Reasoning
- Principle
- Specific Instances generalization
- Analogy
- Causal
- Audience Connection
- With Content Mental Dialogue
- With Structure
- With Delivery
18Analyzing Bursting the Antibacterial Bubble
- Specific Purpose
- To persuade my audience that the federal
government and consumers must act to deal with
the problems created by the use of antibacterial
household problems. - Central Idea
- The use of antibacterial household products
is creating health and environmental problems
that require action by government and consumer
alike.
19Sample Speech on Antibacterials
- Attention
- Compares plotline of movie Boy in the Plastic
Bubble with the overuse of antibacterial
produces. - Credibility
- Studied antibacterial products in public health
class - Read research on the topic
- Topic revealed..yes
- Relating to the audience
- Before I learned more I used these products and
my survey shows that 70 of you do too. - Language use of you we ourselves
- Preview
- These products create more problems than they
solve. - Well look at some solutions.
20Building the Persuasive Speech
- I. Use of antibacterial products causes many
serious problems. - A. Their use is widespread.
- B. They are not effective.
- C. They increase the chance of getting sick.
- D. They harm the environment.
- II. The problems of antibacterial products can
be solved through actions by the federal
government and consumers. - A. Government must regulate antibacterial
products. - B. Consumers, you, should stop using
antibacterial products.
21Problem Issue Evidence
- Use of Antibacterials is widespread.
- Statistic
- Alliance for the Prudent Use of Antibiotics says
75 of liquid soaps and 33 of bar soap are AB. - Brief examples (shows products)
- Boston Globe reports other large items like
mattresses. - Testimony from New York Times the biggest
marketing coup since bottled water.
22Problem Issue Evidence
- Antibacterials are not effective
- Study by Elaine Larson, assoc. dean of the
Columbia School of Nursing shows statistical
evidence - Study by Eric Kupferberg, assoc. director of the
Harvard School for Public Health offers
testimony. - Dr. Larson testimony
- Cold and flu are from viruses not bacteria, so
these products cant prevent those diseases
23Problem Issue Evidence
- Antibacterials can increase illness.
- Testimony from Stuart Levy, prof. of microbiology
and medicine at Tufts. - Testimony from Dr. James Chin, research scientist
from South Wales. - Low dose exposure to bacteria and viruses keeps
us healthy. - Testimony from Dr. Myron Genel, Chair of the AMA
council on scientific affairs. - Antibiotic resistant bacteria are untreatable
24Problem Issue Evidence
- Antibacterials appear to harm the environment
- Testimony, Rolf Halden of Johns Hopkins reports
on antibacterials in the water supply. - Testimony U.S. Geological Survey reports
antibacterial chemicals in remote water. - These chemicals are known to pollute the water
supply, disrupt fish reproduction and growth.
???
25Plan Practicality Issue
- Federal legislation should regulate the use of
antibacterial products. - FDA regulates antibiotics by requiring
prescription from a doctor so they can regulate
this. - You should stop buying these products.
- Centers for Disease Control testimony says you
can keep germs away by using regular soap. - Study at U North Carolina found hand washing to
be more effective. - Sickbert-Bennet , public epidemiologist,
testimony that it is more practical since you
wash away germs rather than rubbing them into
your skin.
26Appeals in Antibacterial Speech
- Ethos
- Lots of testimony with clearly identified and
credible sources - Obvious personal concern
- Pathos
- Personal concern esp. antibiotic resistance and
environmental issue - throwing our money away
- Logos
- Central appeal of this speech
- Antibacterials cant kill the viruses that cause
disease dont work cause harms
27Patterns of Reasoning
28Read the following passage out loud.
- FINISHED FILES ARE THE RE-
- SULT OF YEARS OF SCIENTIF-
- IC STUDY COMBINED WITH
- THE EXPERIENCE OF YEARS.
29Reasoning deduction induction
- Deduction arguments that run from general to
specific they are characterized by necessity. - Induction arguments that run from specific to
general they are characterized by an inductive
leap.
30Classic form of Deduction the syllogism
- The U.S. Constitution guarantees citizens the
right to vote. - Women are citizens.
- The U.S. Constitution guarantees women the right
to vote.
31Induction Deduction
- Argument in yesterdays Daily that the Supreme
Court should rule that lethal injection is
inhumane. - Sodium pentothal wears off before death causing
extreme pain. - Trapped prisoner cannot speak.
- Texas has banned the use of these drugs to put
dogs and cats to sleep. - The example of Angel Diaz..took 37 min. and two
injections and he was conscious for 24 minutes. - And so lethal injection is not humane.
- INDUCTION
32Deduction or Argument from Principle
- There is no form of execution that can be made
humane. - Lethal injection is a form of execution.
- Lethal injection can not be made humane.
33The Enthymeme
- Assumes that the audience will supply a part that
is missing. - Shes a girl she cant throw the ball.
- Girls cant throw balls.
- Hes a man he wont stop to ask directions.
- Men wont stop to ask directions.
- The people of Iraq are intelligent people, they
support Democracy. - Intelligent people support Democracy.
34Enthymemes
- 16 year olds have undeveloped brains so they
cant judge risks. - People with undeveloped brains cant judge risks.
- By writing a letter to your representative, you
can help pass this law. - Writing letters leads to passing new laws.
35Beware the false principle
- The police say he committed the crime, so he
committed the crime. - stereotypes
- starting from principles that only those who
already agree with you would maintain.
36Inductive reasoning specific instances
- Otherwise known as generalization arguments.
- Surveys and studies are often grounded in
reasoning from specific instances. - Neilson ratings and representative samples
- composed of a cross-section of nearly 10,000
representative homes throughout the United
States
37Specific Instances Antibacterial Soaps
- Antibacterials are not effective
- Study Columbia School of Nursing shows people who
use are just as likely to get sick as those who
dont. - Testimony by Eric Kupferberg products dont
lower the of germs you encounter. - Dr. Larson testimony
- Cold and flu are from viruses not bacteria, so
these products cant prevent those diseases
38Specific Instances Teen Driving Speech
- There are too many car accidents, death and
injuries involving teen drivers. - National Hwy Safety Administration Info
- 7 of drivers, but are 14 of fatalities
- 3,657 teen drivers killed last year
- 2,384 teen passengers killed
- 2, 625 21 and older killed in accidents with teen
drivers - Insurance Institute for Highway Safety
- Teens have highest of crashes caused by
speeding, and driver error and the most single
car crashes - USA Today says 16 yr olds are 3 times more likely
to be in a fatal crash than older drivers.
39Beware the Hasty Generalization
- my friends and I watched violent cartoons and
never committed a crime, so . . . . - the two people I sat next to in lecture got Bs on
their speeches, so everybody but me got a B on
the speech. - but Mom, everybody else is going to the party!
- which moves us toward the bandwagon fallacy
40Arguments from Analogy
- Figurative
- He wont make a good company president because
you cant teach an old dog new tricks - Literal
- Socialized medicine works in Canada, so
socialized medicine will work in the U.S. - both are grounded in the concept of similarity
41Figurative Analogies
- Useful for framing an argument
- Not useful as proof/evidence
- It doesnt really pass the test of similarity
- It is typically heard as pathos not logos
42Figurative Analogy
- Malcolm X on integrating the
- Civil Rights Movement
- "Its just like when youve got some coffee
thats too black, which means its too strong.
What do you do? You integrate it with cream, you
make it weak. But if you pour too much cream in
it, you wont even know you ever had coffee. It
used to be hot, it becomes cool. It used to be
strong, it becomes weak. It used to wake you up,
now it puts you to sleep." - "Message to the Grass Roots," speech, Nov. 1963,
Detroit (published in Malcolm X Speaks, ch. 1,
1965).
43Analogies can help prove claims
- When it comes to putting down cats and dogs,
Texas bans the use of the lethal injection drugs
used to execute death row inmates. - If such drugs are too inhumane to use on animals,
they are too inhumane to use on people. - The cases compared are literally similar.
44Analogies can help prove practicality
- We can solve the problems of antibacterial
products by government regulation. - The government already regulate antibiotics since
you need a prescription to get them. - So the government can regulate antibiotics in
consumer products.
45Analogies can help prove practicality
- We eliminated the half penny in 1857 without
harmful effect, so we can eliminate the penny
today.
46Weak Analogies?
- A ban on all alcohol use in the dorms will work
at ISU because such a ban worked at Luther
College. - The university shouldnt be able to tell me what
classes I have to take after all, the store
manager doesnt tell me what groceries to buy. - We praise the lives of soldiers who sacrificed
their lives for the sake of others, why cant we
celebrate embryos sacrificed in order to save the
lives of others?
47Causal Arguments
- The most challenging of the types of reasoning.
- We cant see causal relationships, we can only
infer them. - Examples
- cigarettes cause lung cancer
- Billing problems at bookstore cause overdraft
fees
48Causal Argument Challenges
- post hoc ergo propter hoc
- after this therefore because of this
- confusing a relationship in time with cause and
effect - seen in superstitions
- seen in just look what happened after we . . . .
arguments.
49Causal Argument Challenges
- multiple causation
- rainforest destruction is the cause of global
warming - T.V. is responsible for school violence.
- my printer problem caused me to be unable to do
my speech - correlation vs. causation
50Causal Reasoning
- Antibacterial Products
- Dr. Larson testimony
- Cold and flu are caused by viruses not bacteria,
so these products cant prevent those diseases - Chewing Tobacco
- causal chain Chewing tobacco contains grit and
sand, which wear away at teeth it also contains
sugar which wears away at teeth, leading to
cavities and then tooth loss. Loss of teeth in
turn can encourage gum disease, which can lead to
additional tooth loss.
51Tips for success in causal reasoning.
- use causal chains to help the audience see the
causal relationship. - use testimony of experts to support conclusions
- combine them with specific instances arguments
52Fallacies of Reasoning
- False principle
- Hasty generalization
- Weak (invalid) analogy
- Post Hoc or false cause
53Additional Fallacies
- Bandwagon
- Red herring
- Slippery slope
- Ad hominem
- Either-or
54Practice
55What kind of reasoning and how strong is it?
- According to a study by the American Medical
Association, men with bald spots have three times
the risk of heart attack as men with a full head
of hair. Strange as it may seem, it looks as if
baldness is a cause of heart attacks. - The U.S. Constitution guarantees all citizens the
right to bear arms. Gun control legislation
infringes on the right of citizens to bear arms.
Therefore, gun control legislation is contrary to
the Constitution.
56More practice
- If we encourage elementary school students to use
computers in class, they will spend less time
reading books. As a result, they will fall
behind in developing reading, writing and
thinking skills. Pretty soon well have a
generation of illiterates on our hands. - Raising a child is like having a pet--you need to
feed it, play with it, and everything will be
fine.
57More practice
- I dont see any reason to wear a helmet when I
ride a bike. Everyone bikes without a helmet. - There can be no doubt that the Great Depression
was caused by Herbert Hoover. He became
President in March 1929, and the stock market
crashed just seven months later.
58More practice
- Its ridiculous to worry about protecting
Americas national parks against pollution and
overuse when innocent people are being killed by
domestic terrorists. - I cant support Representative Freys proposal
for campaign finance reform. After all, he was
kicked out of law school for cheating on an exam.
