1. Crafting an Argument

2. RHETORICAL STRATEGIES

3. 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

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

5. Using Logic: Deductive Reasoning
• More formal & complex
• Generalization- Specific Conclusion
• Syllogism
– Major Premise
– Minor Premise
– Conclusion

6. Avoiding Logical Fallacies
• Oversimplification
• Generalization
• Post Hoc
• Circular Reasoning
• False Analogy
• Either/or thinking
• Non Sequitur
• Ad hominem

compelling?
What is the temperament of your audience?
• Establish tone

agreement/possible compromise
