Q

Deductive argument

A

Refers to an argument that claims that it is impossible for the conclusion to be false, given that the premises are true

–> based on facts/necessary reasoning

19
Q

Inductive argument

A

Refers to an argument that claims that it is improbable that the conclusion is false given that the premises are true

–> based on opinions/probabilistic reasoning

20
Q

Valid deductive argument

A

Suggests that the conclusion true given that the premises are true

e.g.: invalid = opposite

21
Q

Sound argument

A

Refers to a deductive argument that is valid + has all true premises

= good argument

e.g.: unsound argument = invalid + false premises

22
Q

When one has a good argument and adds an

unsound argument will the argument still be sound ?

A

Yes, because the premise should not be considered as part of the argument

23
Q

Strong inductive argument

A

Suggests that it is improbable that the conclusion is false given that the premises are true

24
Q

Weak inductive argument

A

Refers to an argument in which the conclusion does not follow probably from the premises even though it is claimed to

25
What is the difference between strong inductive + valid deductive arguments ?
1. If the conclusion of deductive arguments is true independently of the premises, then the argument is still considered valid 2. If the conclusion of an inductive argument is probably true independently of the premises, then the argument is weak
26
How do you know if an | inductive argument is strong ?
If it is more than 50% probable
27
Cogent argument
Refers to an inductive argument that is strong + has all true premises e.g.: uncogent= opposite
28
Counterexample method
Isolates the form of an argument, then constructs a substation instance having true premises + false conclusion --> proves the invalidity of any invalid argument but can't prove validity
29
Definiendum
Refers to the word/group of words that is defined
30
Definiens
Refers to the word/group of words that does the defining
31
Name the 4 different Deductive argument forms.
1. Argument based on mathematics 2. Argument from definition 3. Hypothetical syllogism - -> if .. then 4. Disjunctive syllogism - -> either .. or
32
Name the 6 different Induction argument forms.
1. Prediction 2. Argument from analogy - -> similarity of things 3. Generalization - -> sample is used to make claim about whole group 4. Argument from authority - -> expert as reference 5. Argument based on signs 6. Causal inference
33
Name the 2 different types of cognitive meaning.
1. Intensional meaning/Connotation - -> qualities, attributes of the term ex.: cats = furry, 4-legged, pet 2. Extensional meaning/Denotation - -> class members of the term ex.: cats = all cats in the world
34
Stipulation definition
Assigning a meaning to a word for the first time
35
Lexical defintion
Reporting the meaning that a word already has in a language
36
Precising definition
Reducing the vagueness of a word
37
Theoretical defintion
Assigning a meaning to a word by suggesting a theory that gives a certain characterization to the entities that the term denotes
38
Persuasive defintion
Engendering a favorable attitude toward what is denoted by the definiendum --> assigning an emotionally charged meaning to a word ex.: abortion means the ruthless murdering of innocent human beings
39
Multilayered arguments
Refer to arguments in which reasons or objects have drawn out new reasons or objections ex.: rebuttal, refutation
40
Rebuttal
When a reason is followed by an objection within an argument a) Counterargument to a premise b) Counterargument to a conclusion
41
Counterargument to a premise | Rebuttal
Showing that the reasons contention is false
42
Counterargument to a conclusion | Rebuttal
Showing that the contention doesn't provide enough proof to support the conclusion
43
Refutation
If an objection is followed by an objection within an argument a) Refutation to the premise b) Refutation to a conclusion
