  1. LOGIC!

  2. How do we use logic to back up a claim? • Discuss your assigned question. State your position on the issue as a group and support with specific details. • What is the strongest motivator for us to do the work we do? • What is the biggest way that work shapes or influences our lives? • Which is the stronger motivator: internal factors or external ones? • Can America honestly be called “the land of opportunity”? Why or why not? • What about the claims and supports that you created and heard would you consider “logical”? • How do we define “logic”?

  3. LOGOS: Appealing to logic • Claims need support for an audience to trust you as a writer. • Two main types of support: • Hard evidence • Facts, Statistics, Surveys and Polls, Testimonies and Narratives • Reason and Common Sense • Drawing conclusions and making inferences • In the absence of hard evidence, reason and common sense can make an effective argument. • BUT a balance of both is likely to be more persuasive.

  4. Inductive vs. Deductive Reasoning • Inductive Reasoning: generalizing based on a number of specific examples. Specific to general • I get hives after eating crawfish • My mouth swells up when I eat clams • Shrimp triggers my asthma • Shellfish makes me sick • Deductive Reasoning: reaching a logical conclusion based on a general principle. General to specific • Shellfish makes me sick • Lobster is a type of shellfish • Lobster will make me sick
