Reasoning Chapter 16

What is Reasoning? Reasoning is the process by which we come to understand something new, through analyzing and synthesizing what we already know. Sprague Chapter 16 21

What is Reasoning? ** This concept is the foundation for thoroughly developing a thesis...and for an audience’s critical evaluation of the content used to support your thesis. ** Sprague Chapter 16 22

Identify Where Reasoning is Needed to Link Points Evidence can lead to more than one claim People look for familiar patterns Sprague Chapter 16 23

Inductive Reasoning Collecting enough instances to establish a pattern or drawing inferences/conclusions from observations. Sprague Chapter 16 24

Inductive Reasoning Base inferences on sufficient and representative cases Recognize the degree of probability of your claim Demonstrate your cost-rewards analysis Sprague Chapter 16 25

Deductive Reasoning Making verbal statements, or premises, according to formal rules or reasoning from generalizations to specific conclusions. Sprague Chapter 16 26

Deductive Reasoning Finds the patterns in what you already know In a formal deductive syllogism, the major premise sets up an absolute relationship Sprague Chapter 16 27

Deductive Reasoning Probable premises can lead only to probable conclusions Lay out all the premises of a deductive argument Sprague Chapter 16 28

Causal Reasoning Is the backbone of all speeches that deal with policy and problem solving and is reasoning that one cause invariably leads to one effect Sprague Chapter 16 29

Causal Reasoning • Test the validity of your causal relationships • Do the alleged cause and alleged effect occur together? • Do the alleged cause and alleged effect vary together? Sprague Chapter 16 30

Causal Reasoning • Do not simplify the relationship • Some effects have multiple causes • Some cause are also effects • Explain your causal claims fully and fairly Sprague Chapter 16 31

Reasoning by Analogy When we reason by analogy, we compare two things that can be placed in the same category Sprague Chapter 16 32

Reasoning by Analogy Compares two things in the same category Be sure that the two cases are similar Sprague Chapter 16 33

Reasoning by Analogy • Do not confuse a literal analogy with a figurative analogy • Literal analogy compares the members of the same category • Figurative analogy compares the members of different categories Sprague Chapter 16 34

Avoid Common Reasoning Fallacies Ad hominem – attacking the person instead of the argument “Setting up a straw figure” – setting up a poor argument, attributing it to the other side, and refuting it. Sprague Chapter 16 35

Avoid Common Reasoning Fallacies Extending an argument to absurd lengths – goes beyond a reasonable interpretation of the original point Sprague Chapter 16 36

Avoid Common Reasoning Fallacies Slippery slope - false assumptions that if one takes a particular first step then they will automatically take other dangerous steps in the same direction. Sprague Chapter 16 37

Avoid Common Reasoning Fallacies Circular reasoning - assumes as one of its premises the very conclusion it sets out to establish Semantic fallacy – when meanings of word shift mid argument Sprague Chapter 16 38

Avoid Common Reasoning Fallacies False dichotomy – is reasoning based on an either-or statement when the two alternatives are not mutually exclusive Sprague Chapter 16 39

Avoid Common Reasoning Fallacies Faulty reversal of an if-then statement - affirming the consequent or denying the antecedent Sprague Chapter 16 40

Avoid Common Reasoning Fallacies • Hasty generalization - making a premature general conclusion • Confusing sequence with cause • Post hoc fallacy Sprague Chapter 16 41

Show How Your Reasoning Links Your Evidence to Your Claim Organize points to show the logical relationship Select language that shows the logical relationship Sprague Chapter 16 42

When we reason by -------, we compare two things that can be placed in the same category. analogy

Of the four patterns of reasoning, ------- is the simplest and most common, and consists of collecting enough instances to establish a pattern. Inductive reasoning

Among the various ‘reasoning fallacies,’ ----- is attacking the person instead of the argument Ad hominem
