CS 100 - Week 7 Lecture 1 - 10-2-12
* yes, an argument CAN contain multiple logical
fallacies;
* some distinguishing features between "look who's talking"
and "2 wrongs make a right"
..."look who's talking" always involves a charge of
hypocrisy or failing to practice what one preaches;
..."2 wrongs make a right" always involves attempting
to justify an apparent wrongful act
Scare Tactics
--------------
* the fallacy of scare tactics is committed when the
arguer threatens harm to a reader or listener
if he/she does not accept the arguer's conclusion,
AND this threat is irrelevant to the truth of the
arguer's conclusion.
Appeal to Pity
--------------
* the fallacy of appeal to pity occurs when an arguer
inappropriately to evoke feelings of pity or compassion
from the listeners/readers AND this appeal is
irrelevant to the truth of the arguer's conclusion.
Bandwagon argument
------------------
* a bandwagon argument in one that plays on a person's
desire to be popular, accepted, valued, cool, etc.
RATHER than appealing to logically relevant reasons or
evidence
Straw Man
---------
* the straw man fallacy is committed when an arguer
distorts an opponent's argument or claim to make
it easier to attack,
they give premises again this distorted claim that
ISN'T the actual opponent's claim,
and then claim their premises against the distorted
claim are reasons to reject the opponent's actual claim.
* ALWAYS involves misrepresenting another person's
argument or claim
Red Herring
-----------
* the red herring fallacy is committed when an arguer
tries to sidetrack his/her audience by raising an
irrelevant issue and then claims that the original
issue has been effectively settled by the irrelevant
diversion
BUT it hasn't been, really, because the diversion
was indeed not supportive one way or the other
to the original argument;
* ALWAYS involves changing or evading the issue
Equivocation
-------------
* words CAN have more than one meaning;
* the fallacy of equivocation is committed when a key word
is used in two or more senses in the same argument
AND the apparent success of the argument depends on
that SHIFT in meaning;
Begging the question
---------------------
* the fallacy of begging the question is committed when
an arguer states or assumes as a premise the
very thing he/she is trying to prove as a conclusion.
* two common forms:
...just restate the conclusion a little differently
as a premise;
...you circularly reason to it;
