Rhetoric
Rhetoric
 Rhetoric is the art of using words to persuade in
writing or speaking
 All types of writing seek to persuade
 In writing arguments, consciously structure writing
using logical lines of reasoning such as order of
importance, chain of reasoning, cause & effect,
rebuttal, concession/refutation.
Purpose of using effective rhetoric
 This might be to:
 Support a cause
 Promote a change
 Refute a theory
 Stimulate interest
 Win argument
 Arouse sympathy
 Provoke anger
Audience
 Questions to ask oneself before writing:
 Who exactly is the audience?
 What do they know?
 What do they believe?
 What do they expect?
 How will the audience disagree with me?
 What will they want me to address or answer?
 Should I use language that is formal, factual, and objectiveor familiar, anecdotal, and personal?
Modes of Discourse
 Logos: logical appeals
 Pathos: emotional appeals
 Ethos: appeal to credibility/ethics
Logos
 You appeal to logos if you:
 Cite commonly held beliefs
 Allude to history, religious texts, literature, mythology
 Draw analogies/create metaphors
 Provide evidence
 Quote research
Pathos
 You appeal to pathos if you:
 Use language that involves the senses
 Include a bias or prejudice
 Include an anecdote
 Include connotative language
 Explore euphemisms
 Use description
 Use figurative language
 Develop tone
 Experiment with informal language

Logical Fallacies
 Do not claim too much
 Do not oversimplify complex issues
 Support your argument with concrete evidence and
specific proposals
Logical fallacies
 Ad hominem: “to the individual,” the target person’s
characteristics are attacked, instead of the argument
Logical fallacies
 Ad populum: “to the crowd,” a misconception that a
widespread occurrence of something is assumed to
make an idea true/right
Logical fallacies
 Begging the question: taking for granted something
that really needs proving
Logical fallacies
 Circular reasoning: trying to prove one idea with
another idea that is too similar to the first idea
 Logic moves backward in its attempt to move
forward
Logical fallacies
 Either/or reasoning: the tendency to see an issue as
having only two sides
Logical fallacies
 Hasty generalization: drawing a general and
premature conclusion on the basis of only one or two
cases
Logical fallacies
 Non sequitur: “it does not follow,” an inference or
conclusion that does not follow established premises
or evidence
Logical fallacies
 Post hoc: “after this, therefore because of this,”
assuming that an incident that precedes another is
the cause of the 2nd incident
Logical fallacies
 Propaganda: writing or images that seek to persuade
through emotional appeal rather than logical proof;
written or visual texts that describe or depict using
connotative words or images without justification
Modes of discourse
 Describe the variety, conventions, and purposes of
writing and speaking
Modes of Discourse
 Description: the traditional classification of
discourse that depicts images verbally and arranges
those images in a logical pattern
Modes of Discourse
 Narration: the classification of discourse that tells a
story or relates an event. Narration generally tells
what, when, and where it happened.
Modes of Discourse
 Exposition: one of the traditional classifications of
discourse that has a function to inform or to instruct
or to present ideas and general truths objectively.
Exposition can use:
Modes of Discourse
 Comparison: showing a subject more clearly by
showing how it is similar to something else
 Contrast: which ways the subject is unlike another
subject
 Cause and effect
Modes of Discourse
 Classification: one of the traditional ways of thinking
about a subject. Classification identifies the subject
as a part of a larger group with shared features
 Definition: places a subject into an appropriate
group and then differentiates the subject from the
other sections of the group. In prose, definitions are
often extended by illustrations and examples.
Classical Argumentative Scheme
 Pt. 1: Introductory Paragraph
 Catch interest
 Present the issue or topic with concrete image or anecdote
 Provide any relevant background information
 Define pertinent terms
 State claims
Classical Argumentative Scheme
 Pt. 2: Confirmation Paragraphs
 This is the most important and longest section of the argument
 It provides the reasons and evidence of a writer’s claim
 This section is the body of the essay that shows the logical
development of the argument
Classical Argumentative Scheme
 Pt. 3: Concession and Refutation
 This first briefly recognizes and then at length argues against
opposing viewpoints by finding weaknesses within the
opposing reasons, facts, testimony, or logical development.
 It is the “yes…but” part of the argument

It is the “yes…but” part of the argument
“Yes” is the concession
“But” is the refutation

This allows writers to grant validity to or acknowledge
opposing views
Ideas of concession often appear as subordinated thoughts in
dependent clauses of the sentence
Classical Argumentative Scheme
 Pt. 3: Concluding Paragraph
 Wrap up the argument
 Restate the claim
 Provide a new appeal to needs of values
 Enrich with additional commentary
 Voice a final plea for readers to take action or to change
thinking
 Refrain from repeating any information
