Types of Evidence (3)

Test of Argument Worthiness
1. test of truthfulness of premises 2. test of logical strength 3. test of relevance 4. test of non-circularity
test of truthfulness of premises
test condition- reason is true in each of its premises, explicit and implicit
test of logical strength
condition- if the reason were true then the claim would be very true
test of relevance
truth of the claim depends on the truth of the reason; requires that the source's reason is the basis for the claim
test of non-circularity
truth of reason does not depend on the truth of the claim
If all reasons are true but claim is false
fails test of logical strength
if all reasons are true but it is not possible for claim to be false
argument passes logical strength test
Fallacies of Relevance (7)
appeals to ignorance appeals to the mob (bandwagon) appeals to emotion ad hominem attack straw man playing with words misuse of authority
appeals to ignorance
occur when absence of reason is used to reject the claim ex- Since there are not questions from the class regarding fallacies, then they must understand them.
appeals to the mob
error in reasoning to assume that because others are doing it or believe that it is correct
appeals to emotion
occurs when we rely upon an emotional response as the best guid for forming decision ex- Mom said there were starving children all over the world who would give anything for the pickled beets on my plate, so I gave in and ate them.
ad hominem attack
when someone is personally attacked rather than his or her ideas ex- After Sally presents an eloquent and compelling case for a more equitable taxation system, Sam asks the audience whether we should believe anything from a woman who isn't married, was once arrested, and smells a bit wei…
straw man
idea that refuting the weakest argument is enough and saying the entire claim should be denied when one person attributes to the other an argument that the other person did not say
playing with words
when an argument exploits problematic vagueness, ambiguity, stereotyping, donkey cart langued or slanted langue
misuse of authority
error in reasoning that occurs we we believe a claim because a powerful or respected person says it
Deductive Arguments
require that the conclusions are true if the reasons are true
Denying the consequent
#1: If A, then B #2: Not B Conclusion: therefore, A ex- if the gate is open then he'll go in he didn't go in then the gate wasn't open
Affirming the antecedent
#1: If A, then B #2: A Conclusion: then B ex- if you play with fire you'll get burned I played with fire you got burned
Disjunctive Syllogism
#1: Either A or B #2: Not A Conclusion: then B ex- either you go to the play or we see a movie we didn't go to the play then you saw a movie
Applying a Generalization
#1: every member of F is a member of G #2: X is a member of F Conclusion: so X is a member of G ex- every teacher is in the teacher's union she's a teacher then she's in the union
Applying an Exception
#1: every F is a G #2: X is not a G Conclusion: X is not an F ex- every song has a tune  chants don't have a tune then chants are not songs
The Power of Only
only is one of the most interesting words in our language extraordinarily
transitivity relationship
if x has a transitive relationship to y, and y has the same transitive relationship to z, then x has the same transitive relationship to z ex- The team with the best record is the Mountaineers. The team with the best record should win the trophy. So, the Mountaineers should win the troph…
reflexivity relationship
if x has a reflective relationship to y, then y has the same reflective relationship to x ex- Danielle is Carrie's sister. So Carrie is Danielle's sister.
Fallacies in Declarative Statements
affirming the consequent denying the antecedent
affirming the consequent
#1: if a, then b #2: a conclusion: b ex- if im in morgantown im in west virginia Im in west virginia therefore im in morgantown
denying the antecedent
#1: if a, then b #2: not a conclusion: not b ex- if im not in morgantown im not in west virginia im not in morgantown then im not in west virginia
fallacies when reasoning about classes of objects
false classification fallacies of composition and division
false classification
one feature can be true of one group without requiring that one group be apart of the other
fallacies of composition and division
attributes that apply to parts of a whole may not apply to entire division- occurs when we say what is true of the group is true of individuals composition- true about parts is true about whole
Fallacies of false reference
just because something is described in one way does not mean that the person knows same things described in another way
