Chapter 17
Appeal to tradition
-assumes that something old is automatically better than something new -its value should be based on its contributions to society, not its age
Slippery Slope
-assumes that taking a first step will inevitably lead to second and so on forth until disaster
Ad Hominem
-attacking the other person rather than dealing with the real issue in dispute
Appeal to novelty
-assumes that because something is new, it is therefore superior to something that is older
Bandwagon
-assumes that because something is popular, it is therefore good, correct, or desirable
Either-Or
-forces listeners to choose between two alternatives when more than two alternatives exist
Identify fallacies in reasoning through examples
-hasty generalization, false cause, invalid analogy, bandwagon, red herring, ad hominem, either-or, slippery slope, appeal to tradition, appeal to novelty,
Red Herring
-introduces an irrelevant issue in order to divert attention from the subject under discussion
Hasty generalization
-most common fallacy -occurrs when a speaker jumps to a conclusion on the basis of too few cases or on the basis of atypical cases
Reasoning from principles
-move from general to specific (used when trying to persuade an audience) -general principle to minor premise to final conclusion
Reasoning from specific instances
-progress from a number of particular facts to a general conclusion -beware of jumping to conclusions from insufficient evidence -sample of small instances needs to be large enough to justify your conclusion -instances are fair, unbiased, and representative -reinforce argument with statistics or testimony
Identify the types of reasoning through examples
-reasoning from specific instances, from principles, casual reasoning, analogical reasoning
Casual Reasoning
-someone tries to establish the relationship between causes and effects -used daily -beware of the temptation to attribute complex events to single causes
Analogical Reasoning
-speaker uses two similar cases and infers what it true for one case must be true for the other -used in persuasive speeches and can be used on both sides of an issue
False Cause
-the fact that one event occurs after another yes not mean that the first is the cause of the second, can be entirely coincidental
Identify methods for generating emotional appeal
-use emotional language, develop vivid examples, speak with sincerity and conviction
Invalid Analogy
-when two cases are being compared that are not essentially alike
