Focusing on someones past words or actions instead of the truth of their current claims - hypocrisy
27
Ad hominem tu quoque example
"You can't tell me to not eat cheeseburgers, I saw you eating one last week!"
28
When is an ad hominem attack not fallicious?
If the attack they make is relevant to the argument
29
Legitimate ad hominem example
"You can't say that eating five cheeseburgers a day is healthy, you haven't been to medical school!"
30
Appeals to authority types | 2
* Legitimate * Illegitimate
31
What should legitimate appeals to authority contain? | 3
* Be making a claim within their area of expertise * Have sufficient expertise in a relevant subject * Be free of significant bias
32
Legitimate appeal to authority example
"As a mathematician, I think that maths is easy because it is straightforward and easy to learn"
33
Illegitimate appeal to authority definition
When a claim is accepted because a person asserts it to be true, but the person has no authority on the matter
34
Illegitimate appeal to authority example
"I am a mathematician, and I think that skechers are the only good shoe on the market"
35
Post hoc ergo propter hoc definition
When someone falsely assumes that because one event was followed by another it was caused by the first event - mistakes correlation with causation
36
Post hoc ergo propter hoc example
"I wore my blue socks and passed my driving test, so I passed my driving test because I wore my blue socks"
37
Appeals to emotion definition
When someone uses emotion in place of reason to attempt to win an argument - a form of manipulation
38
Appeals to emotion example
"You should give me that job promotion because I've just gotten a divorce, I've lost my house and I'm feeling really sad"
39
When is an appeal to emotion not fallicious?
When the emotion is relevant to the argument
40
What are the formal fallacies? | 2
* Denying the antecedent * Affirming the consequent
41
What are the antecedent and consequent in an argument?
If I have caffeine **(antecedent)**, I will be awake all night **(consequent)**
42
Denying the antecedent definition | 2
* An argument in the form: *If P, then Q. Not P, therefore not Q.* * This is the error of mistaking a sufficient condition for a necessary condition
43
Denying the antecedent example
"If I am in Paris, I am in France. I am not in Paris, so I am not in France."
44
Affirming the consequent definition | 2
* Any argument in the form: *If P, then Q. Q, therefore P* * This is the error of mistaking a necessary condition for a sufficient condition
45
Affirming the consequent example
"If I am in Paris, I am in France. I am in France, therefore I am in Paris"
46
What are the types of argument diagrams? | 3
* Linked arguments * Convergent arguments * Serial arguments
47
Linked argument definition
When all the premises are necessary (and linked to eachother) to establish the conclusion
48
Linked argument example
P1: Jeff goes to work everyday in his car (AND) P2: Jeff's car hasn't moved in a week (AND) P3: It hasn't broken down (THEREFORE) C: Jeff is dead
49
Convergent argument definition
When all premises independently support the conclusion
50
Convergent argument example
P1: Jeff has no lights on in his house, day or night (ALSO) P2: Jeff drives to work, and I haven't seen his car move in over a week (ALSO) P3: Jeff's mailbox is overflowing (THEREFORE) C: Jeff is dead
51
Serial argument definition
When all premises are necessary to support the conclusion, but one of them serves as an intermediate conclusion
52
Serial argument example
P1: Jeff has no lights on in his house, day or night (THEREFORE) P2: Jeff is either dead or on holiday (THEREFORE) P3: I should investigate further (THEREFORE) C: I will phone jeff's mobile or chap his front door
53
What is an analogical argument?
An argument that attempts to establish that two things are similar in some respect because they have some other feature in common
54
What is an inappropriate analogy / disanalogy?
An analogical argument that has significant and relevant differences which outweigh the similarities of what is being compared
55

* Lexical * Syntactic
56

What is syntactic ambiguity?
When a sentence has more than one possible meaning, which is confusing
58
What is confirmation bias?
Involves seeking evidence that confirms your belief and ignoring evidence that would disprove what you already believe
59

60
What features should a premise have to be acceptable? | 6
* Is known a priori to be true * Is known to be true or can be accepted as true * Is a matter of common knowledge * Is plausible to be true * Is unambiguous * Appeals to an appropriate authority
61
What features should a premise have to be relevant? | 4
* Provides some justification to support the conclusion * Gives support to another relevant premise * Contains an appropriate analogy * Attacks the claim rather than the person putting forward the claim
62
What is sufficiency?
Exactly what is needed - no more, no less
63
What makes premises sufficient to draw the conclusion?
If they meet the necessary conditions of being acceptable and relevant
