CATA 335 - ARGUMENTATION
A. MISSING GROUNDS -- circularity: 1. "begging the question"
(grounds = claim) Smith must be telling the truth
because he wouldn't lie. 2. circular definition "a cat is a feline animal." "synthesis is the act of
synthesizing" B. IRRELEVANT GROUNDS 1. evading the issue: a.
"red herring" We should not
support Greek Week because Greeks are hazers and sex abusers." "Genetic testing is genocide against
handicappers." b.
"straw man" The students
argued they should have the same parking rights as residents even though they
don't pay property taxes." c. slippery slope/extension "If we allow the Brady Bill waiting
periods for gun purchases, pretty
soon guns will be outlawed entirely." d. tu quoque "You did it too." 2.
appeal to tradition (unchallengeable authority): [religion, tradition, science, etc.] "It's God's will."
"The Bible says so."
"We must support the president.
He's right and knows best."
"Einstein was a Zionist so it must be right." 3. ad hominem (name calling, guilt by
assoc, motive) "commie, racist,
bigot, sexist, fascist", character attacks, motive attacks 4.
ad populi (to the people)
"America is a Christian nation; therefore ..." 5.
emotion/compassion - pity/fear
"People are suffering in this recession therefore we should have a
stimulus package." 6. shifting grounds / shifting the burden of
proof. "They have offered no good
reason not to adopt our policy." 7. two wrongs.
"It's only fair that white males get short changed after they've
done it to others so long." 8. ignorance (of counter evidence) "You don't see any elephants do
you?" "No one has ever been
able to show it's not a good idea/true." C. DEFECTIVE GROUNDS 1. hasty generalization: a. too few cases: "After one semester here I can tell the faculty are
unfriendly" b. unrepresentative cases: "Having seen INTERIORS and THE FRONT I
think Woody Allen movies are too grim." 2. accident (applying a rule as if it MUST
ALWAYS be used) "We can't fund
women's soccer because it's gender exclusive." D. UNWARRANTED ASSUMPTIONS 1. False cause a. post hoc ergo propter hoc "I got sick right after eating at the
cafeteria. It must be their food."
b. Single cause "Joining a fraternity CAUSES low grade points." 2. false analogy Roosevelt's garden hose. [metaphors are especially risky -- "war on drugs."] "Students are our customers." 3. poisoned well ("COMMON SENSE tells us
..." "INFORMED voters believe...") 4. dilemma/dichotomy ("either ‑
or") "Either you're for
affirmative action quotas or you're opposed to equal rights for
minorities." 5.
Composition / division E. Language Fallacies
