CHAPTER 1: 1A RECOGNIZING FALLACIESKEY TERMS AND KEY IDEAS AND SKILLS
Key Terms Logic
Argument – premises, conclusions
Fallacy
Key Ideas and Skills Identify an argument’s premises and conclusions.
Recognize fallacious arguments, which contain logical flaws so that their conclusions are not well supported by their premises
1B: PROPOSITIONS AND TRUTH VALUESKEY TERMS
Key Terms Proposition
Truth values, truth tables
Negation: not p
Conjunction: p and q
Disjunction: p or q
Conditional: if p, then q
Logical equivalence
1B: PROPOSITIONS AND TRUTH VALUESKEY IDEAS AND SKILLS
Understand truth tables for negation, conjunction, disjunction, conditional.
Inclusive vs. exclusive: Inclusive (or) means either or both; exclusive or means one or the other, but not both
Variations on the conditional: if p, then q Converse: if q, then p
Inverse: if not p then not q
Contrapositive: if not q, then not p
1C: SETS AND VENN DIAGRAMSKEY TERMS
Key Terms: Set Categorical Propositions Venn diagrams
1C: SETS AND VENN DIAGRAMSKEY IDEAS AND SKILLS
Set Relationships Subsets, disjoint sets, overlapping sets
Four categorical propositions All S are P;
No S are P;
Some S are P;
Some S are not P
Uses of Venn diagrams Illustrating set relationships
Organizing information
ID: ANALYZING ARGUMENTSKEY TERMS
