23. Appealing to Audience Emotions

24. Appealing to Emotions • Fundamental to motivating an audience • Never a substitute for logical arguments and available evidence

25. Affective Language • Strong language that plays on emotions • Words must be chosen carefully

26. Identifying Shared Values • Show your audience that you share values • Show how your ideas relate to those values

27. Use Vivid Detail • Listeners respond to concrete examples better than abstractions • Speakers can reinforce ideas with vivid details

28. Use Visualization • Helps the audience to “see” • Stirs emotions • Gets audience to think more deeply • Help your audience visualize with a picture • Paint ‘word pictures’

29. Compare Unfamiliar to Familiar • Complicated and even controversial ideas can seem more familiar, and more acceptable

43. The Forms of Reasoning

44. Inductive Reasoning • Moves from a set of specific examples to a general conclusion • A number of representative examples makes the case • Claims must carefully qualified • Reservations may be needed • Can be strengthened with evidence

45. Deductive Reasoning • Draws a conclusion about a specific case based on generally accepted premise • Syllogism is a classic example • Usually we reason from qualified premises to probable conclusions

46. Deductive Reasoning • Premises often already accepted by audience • Speaker may assume the audience will fill in the missing premise • This is “rhetorical syllogism” or enthymeme

47. Causal Reasoning • From effect to cause, or cause to effect • At the heart of scientific investigation • Rarely simple • Reputable sources are important • Qualified due to complexity

48. Analogical Reasoning • What is true in one case will be true in another • Literal analogy compares similar examples • Figurative analogy is similar to metaphor; rarely proves anything • Should be qualified

49. How Patterns of Organization Connect Ideas

50. Chronological or Sequential • Good for step-by-step process or historical events • Begin with a specific point in time, move ahead or back from there
