Crafting an Argument
RHETORICAL STRATEGIES
Logos
• Effective presentation of the argument
• Quality of the thesis/claim, the
  evidence, and the organization
• Logos relies on logic or reason
• Depends on the use of inductive or
  deductive reasoning
Using Logic: Inductive Reasoning

• Scientific method
• Collect evidence on which to base a
  generalization
• Specific Examples- General Statement
• Most common
Using Logic: Deductive Reasoning

• More formal & complex
• Generalization- Specific Conclusion
• Syllogism
  – Major Premise
  – Minor Premise
  – Conclusion
Avoiding Logical Fallacies
•   Oversimplification
•   Generalization
•   Post Hoc
•   Circular Reasoning
•   False Analogy
•   Either/or thinking
•   Non Sequitur
•   Ad hominem
NAME THE LOGICAL
FALLACY!
Maple got a shock right
 after she came home
  from the hair salon.

      salon again.
Comparing high
school to a prison is
a(n) ______________
The president of a
 corporation praises his
employees’ productivity
but then claims that the

      than horror
 movies, dramas, other

    and foreign films.
We need to continue
  testing medicine on
animals. If we stop, we’ll
never again find another
   cure for a disease.
Ethos
• Based on the character, credibility, or
  reliability of the writer. Establish this by:
  – Using only credible, reliable sources and cite
    properly
  – Respecting the reader by stating the
    opposing position accurately
  – Establishing common ground with your
    audience.
  – Disclosing why you are interested in this topic
    or what personal experiences you have had
    with the topic
  – Organizing your argument in a logical, easy
    to follow manner
  – Proofreading the argument
Pathos
• Emotional appeal
• Appeals to an audience's needs,
  values, and emotional sensibilities.
• Sources:
  – Interviews
  – Anecdotes
ELEMENTS OF AN
ARGUMENT
Claims
•   Thesis Statement
•   Position that the writer will argue for
•   Appears in introduction
•   4 Types:
    – Claim of Fact
    – Claim of Value
    – Claim of Policy/Statement
    – Claim of Cause and Effect
Evidence
• Sources:
  – Facts & statistics
  – Examples & narratives
  – Quotations
• Criteria:
  – Accuracy: taken from reliable sources
  – Representation: reflect reality
  – Relevance: current
  – Adequacy: sufficient and appropriate
Assumptions
• Warrants/Bridges
• Connection between the evidence
  and the claims
Counterclaims & Rebuttals
• Consider and acknowledge well-
  known opposing arguments. Why?
• Offer evidence that either negates,
  disagrees, or weakens the
  counterclaim. Why?
PROCESS
Choosing a Topic
• Ask yourself:
  – Does the topic interest you?
  – Is this idea generally accepted?
  – Have you considered both sides?
  – Is it appropriate in scope?
     • If not, include specific
       information, connections, and reasons. Try it
       with these:
        – American high schools do not adequately prepare
          students for college.
        – The drinking age should be changed.
Considering the Audience
     What are the interests and values of your
                    audience?
     Has your audience already established a
                     position?
      What evidence or reasons will they find
                   compelling?
    What is the temperament of your audience?

•   Establish tone
•   Establish common ground with your audience
•   State positions that you have in common
•   Designate areas of mutual
    agreement/possible compromise
Organization
• Introduction:
   – Set the context by reviewing the topic in a general way.
   – Explain why the topic is important or why readers should
     care about the issue.
   – Present a clear, concise, and defined thesis statement.

• Body Paragraphs
   – Each paragraph should be limited to the discussion of one
     general idea
   – Must have some logical connection to the thesis statement
   – Explain how and why the evidence supports the thesis

• Conclusion
   – Restate why the topic is important, review the main
     points, and review your thesis.
   – Offer a suggestion for future research and/or implications
