Transcript Logical Appeals

Rhetoric and Persuasive Rhetoric


Rhetoric: the art of communicating ideas.
Persuasive Rhetoric: reasoned arguments in
favor or against particular beliefs or courses
of action

Will engage both the mind and the emotions of
its readers or audience
 Writer needs to show that his or her position has a
firm moral basis.

Examples:
 Two wrongs do not make a right. Why then would
people advocate for the death penalty? If a society is
trying to show that murdering others is wrong, then
murdering one that commits a crime sets a lousy
example.
 What is the moral basis in the above argument?

and reasons

Logical Appeals
Emotional Appeals
Ethical Appeals


Provide rational arguments to support
writers’ claims
Example: “Declaration of Independence”
 Claim: All men are created equal
 Argument: King George has committed “injuries
and usurpations” that deny those in the colonies
their basic rights. Writers then list these injuries.
(The list of injuries is the logical appeal).

This appeal can be made in two different ways:
 Deductively: Writer begins with a generalization and
then proceeds to give examples and facts that
support this claim.
▪ General to specific
 Inductively: Writer begins with examples and facts
and the reader draws conclusions from them.
▪ Specific to general
 Is the Declaration of Independence inductively or
deductively reasoned?


Appeals to emotion are based on specific
examples of suffering or potential threats.
Often include “loaded language”, which is
language that is rich with connotations and
vivid images.
 Example: “Sinners in the Hands of an Angry God”
 Someone advocating against capital punishment
might detail a specific example of when someone
was exonerated from a crime after they were
already put to death.


Based on shared moral values.
Call forth the audience’s sense of right,
justice, and virtue.
 Two wrongs do not make a right. Why then would
people advocate for the death penalty? If a society
is trying to show that murdering others is wrong,
then murdering one that commits a crime sets a
lousy example.

Elevated Language
Rhetorical Questions
Repetition


Formal words and phrases can lend a serious
tone to a discussion.
Example:
 “The powerful empire of nature is no longer
surrounded by prejudice, fanaticism, superstition,
and lies. The flame of truth has dispersed all the
clouds of folly and usurpation.” – Olympe de
Gouges from “Declaration of the Rights of
Woman”



These are questions that do not require
answers.
Writers pose rhetorical questions to show
that their arguments make the answers
obvious.
Example:
 “Is life so dear, or peace so sweet, to be purchased
at the price of chains and slavery?” – Patrick Henry



Repeating a point or word that tells the audience
that it is especially important.
Parallelism is another form of repetition.
Rhythm of writing.
Example of parallelism:
 “We hold these truths to be self-evident: --That all
men are created equal; that they are endowed by
their creator with certain unalienable rights; that
among these are life, liberty, and the pursuit of
happiness.” – Thomas Jefferson from “Declaration of
Independence

Identify the problem that is addressed and the
solution that is proposed. Restate them in your
own words.
 Analyze the writer’s presentation of his
argument. What rhetorical tools does he use?
 Analyze the evidence used to support the
argument. What facts support the writer’s
opinion?
 Consider how the writer appeals to logic,
emotions, and ethics of his audience.
 Evaluate the credibility of Atticus. What
motivations might lie behind it?
