18
Q

Conjuncts

A

Evaluate each of the conjuncts separately.

Both of them must be true for the conclusion as a whole to be true.

19
Q

Disjuncts

A

On the inclusive interpretation, only one disjunct has to be true for a disjunction, as a whole to be true. If both disjuncts are false, the whole disjunction is false.

20
Q

Exhaustive

A

includes every possibility, complete.

21
Q

Non-exhaustive

A

not complete, partial.

22
Q

Exclusive

A

alternatives rule each other our, you can’t have both.

23
Q

Non-exclusive

A

ones that don’t rule each other out.

24
Q

Fallacy of false dichotomy

A

occurs when the premise(s) claims that a choice between two alternatives is exhaustive or exclusive, or both, when the choice is not.

25
Q

Reportative definition

A

reports the existing meaning of a term

ex: dictionary definitions

26
Q

Stipulative definition

A

words used in a very specific technical way.

ex: valid.

27
Q

Normative definition

A

deriving from a standard or norm.

28
Q

Broad

A

A definition is too broad if it includes things that it should not.

29
Q

Narrow

A

A definition is too narrow if it excludes things that it should not.

30
Q

Fallacy of Equivocation

A

when an ambiguous word or expression is used in 2 different senses in an argument… but the argument appears to suggest otherwise, simply in order to get to its conclusions.

31
Q

Slippery Slope Fallacy

A

occurs when an argument claims or assumes that taking a particular step will inevitably lead to a further, undesirable outcome.

32
Q

Fallacy of Hasty Generalization

A

when an argument concludes something about a group set on the basis of an inadequate sample size.

33
Q

Fallacy of Begging the Question (circular reasoning)

A

attempting to prove a conclusion by using that same conclusion as a premise (sometimes the conclusion is worded differently when its used as a premise, and sometimes its implicit).

34
Q

Fallacy of Composition

A

arguing or assuming that whats true of the parts must be true of the whole.

35
Q

Fallacy of Division

A

arguing or assuming that whats true of the whole must be equally true of the parts.

36
Q

Appeal to Popularity

A

arguing that a claim must be true simply because its a popular belief.

37
Q

Appeal to Common Practice

A

arguing that something should be done in a way simply because its commonly done that way.

38
Q

Appeal to Tradition

A

arguing that a claim must be true simply because its part of a tradition.

39
Q

Appeal to Ignorance

A

an argument which contains an inference, like this:
“We don’t know that P is true, therefore P is false”.
“We don’t know that P is false, therefore P is true”.

40
Q

Ad Hominen (to the person) Fallacy

A

rejecting a claim by criticizing the person who makes it rather than the claim itself.

41
Q

Types of Ad Hominen fallacies

A
  1. ) Character –> premise merely attacks the person.
  2. ) Circumstances –> premise merely points out something about the person’s circumstances.
  3. ) Tu Quoque –> premise merely point out that some claim is inconsistent with some thing else the speaker says or does.
42
Q

Six Basic Rules of Argument Evaluation

A

1) don’t criticize an argument by merely denying its conclusion
2) don’t accept an argument because you believe in the conclusion
3) Direct your criticisms at Individual premises
4) Make sure your criticisms of premise are substantial
5) Don’t accept the conclusions of competing arguments
6) Don’t merely object to intermediate conclusions of compound arguments

43
Q

Cases of conditionals

A

1) When an antecedent is true, the consequent is guaranteed to be true (can rephrase to make obvious)
2) When the antecedent is true the consequent is probably true (rephrase to make connection obvious)
3) When the antecedent is true, the consequent is neither guaranteed to be true nor probably true (should reject)
