Q

fundamental rules

1) golden rule

A

= each single argument really consists of two or more co-premises
- assumes that you need least 1 co-premise (minor premise) to bridge the gap between the major premise and the conclusion

Q

fundamental rules

2) rabbit rule

A

= each significant term that is part of the conclusion should also be part of one of the premises

  • rabbit cannot simply be pulled out of the magician’s hat; it can only be produced if it has been put there beforehand
  • ensures that there is a connection between the premise and the contention

Q
  1. inferential relationship

- inferential claim

A

= there must be a claim that the evidence or reasons support or imply something = claim that the passage expresses a certain kind of reasoning process

  • objective feature of an argument grounded in its language or structure
  • not always easy to detect occurrence of an inferential relationship between statements
  • -> mentally insert ‘therefore’

27
Q
  1. non-arguments

- simple non-inferential passages

A

= unproblematic passages that lack a claim that anything is being proved; no reason/premise to support the conclusion

28
Q

simple non-inferential passages

- warning

A

= form of expression that is intended to put someone on guard against a dangerous situation

29
Q

simple non-inferential passages

- piece of advice

A

= form of expression that makes a recommendation about some future decision

30
Q

simple non-inferential passages

- statement of belief/opinion

A

= form of expression about what someone happens to believe or think about something

31
Q

simple non-inferential passages

- loosely associated statements

A

= statements that lack a claim that one of them is proved by the others

32
Q

simple non-inferential passages

- report

A

= group of statements that convey information about some topic or event

33
Q
  1. non-arguments

- expository passages

A

= kind of discourse that begins with a topic sentence followed by one or more sentences that develop the topic sentence

34
Q
  1. non-arguments

- illustrations

A

= expression involving one or more examples that is intended to show what something means or how it is done

35
Q
  1. non-arguments

- explanations

A

= expression that purports to shed light on some event which is usually accepted as a matter of fact

  1. explanandum = statement that describes the event or phenomenon to be explained
  2. explanans = statement that purports to do the explaining
36
Q
  1. non-arguments

- conditional statements

A

=’if… then’ statement

37
Q

extended arguments

A

1) vertical pattern ≈ chain of reasoning
2) horizontal pattern ≈ composite/convergent argument
3) conjoint premises ≈ co-premises/dependent
4) multiple conclusions

38
Q

deduction

A

= an argument incorporating the claim that it is IMPOSSIBLE for the conclusion to be false, given that the premises are true; the conclusion is claimed to follow with strict certainty

39
Q

deduction

- indicator words

A

= necessarily, certainly, absolutely, definitely

40
Q

deduction

- argument forms

A
  1. argument based on mathematics (exception for statistics) = conclusion depends on some purely arithmetic or geometric computation
  2. argument from definition (definition of words or terms) = conclusion is claimed to depend merely on definition of some word/phrase in premise/ conclusion
  3. categorical syllogism = statements begin with ‘all’, ‘no’ or ‘some’
  4. hypothetical syllogism = have a conditional (if …then) statement for one or both of its premises
  5. disjunctive syllogism = have a disjunctive (either…or) statement
41
Q

validity

A

= determined by the relationship between premises and conclusion; whether the premises support the conclusion

42
Q

valid deductive argument

A

= argument in which it is impossible for the conclusion to be false given that the premises are true

43
Q

invalid deductive argument

A

= argument in which it is possible for the conclusion to be false given that the premises are true

44
Q

deduction

- truth

A
  • knowing the truth tells us nothing about validity
45
Q

deduction

- sound argument

A

= a valid + has all true premises (good argument)

- will have a true conclusion as well

46
Q

deduction

- unsound argument

A

= invalid + one or more false premises or both
- when one has a good argument (valid and true) but adds an unsound argument –> argument would be still unsound (such a premise should not be considered as part of the argument)

47
Q

induction

A

= an argument incorporating the claim is improbable that the conclusion is false given that the premises are true; if it is claimed to follow only probably

  • probabilistic reasoning
  • rely on the uniformity of nature (= future replicate the past)
48
Q

induction

- indicator words

A

= probably, improbably, plausible, implausible, likely, reasonable to conclude

49
Q

induction

- inductive argument forms

A
  1. predictions = from our knowledge of past to a claim about the future
  2. argument from analogy = depends on existence of an analogy, similarity between two things or state of affairs
  3. generalisation = from the knowledge of a selected sample to some claim about the whole group; statistics
  4. argument from authority = concludes something is true because a presumed expert or witness has said it is
  5. argument based on signs = from knowledge of a sign to claim about the thing or situation that the sign symbolises
  6. causal inference = from knowledge of a cause to a claim about an effect or vice versa
50
Q

strength/weakness

A
  • results from the probabilistic support the premises give to the conclusion
51
Q

strong inductive argument

A

= argument in which it is improbable that the conclusion be false given that the premises are true

52
Q

weak inductive argument

A

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

53
Q

induction

- cogent argument

A

= strong + all true premises

- premises must meet the total evidence requirement (= premises do not leave out important factors)

54
Q

induction

- uncogent argument

A

= do not meet the criteria for a cogent argument

- weak + one or more false premises + fails to meet the total evidence requirement or any combination

55
Q

difference between strong inductive + valid deductive arguments

A

1) if the conclusion of deductive arguments is true independently of the premises, the argument is still considered valid
2) if the conclusion of an inductive argument is probably true independently of the premises, the argument is weak

56
Q

valid argument form (deduction)

A

As are included in the Bs, Bs are included in the Cs –> then As must necessarily be included in the Cs

all A are B
all B are C
–> all A are C

57
Q

substitution instance

A

= uniformly substituting terms or statement in place of the letters in an argument form

  • every substation instance of a valid form is a valid argument –> NOT that every substitution instance of an invalid form is an invalid argument
  • counterexample = substitution instance having true premises and a false conclusion
58
Q

counterexample method

A

= isolate the form of an argument –> construct a substitution instance having true premises and a false conclusion

  • proves the form invalid, which in turn proves the argument invalid
  • -> must be known or suspected to be invalid
59
Q

multilayered arguments

A

= argument in which reasons/objections have drawn out new reasons/objections

60
Q

rebuttal

A

= when a reason is followed by an objection

1) counterargument to a premise
2) counterargument to a conclusion

61
Q

rebuttal

1) counterargument to a premise

A

= shows that the reason’s contention is false

- attacks content of the premise

62
Q

rebuttal

2) counterargument to a conclusion

A

= shows that the contention does not provide enough proof to support the conclusion
- attacks the argument (link between claim and reason)

63
Q

refutation

A

= counterargument is itself rejected within an argument

  • if the second objection correct –> ignore first objection
    1) refutation of a premise
    2) refutation of a conclusion
64
Q

complex arguments

- pyramid rule

A

= a well-structured argument has a pyramidal shape

  • the higher up the argument, the more general and abstract it should be
  • when two arguments are placed on the same level, they should have the same level of abstraction
65
Q

complex arguments

- MECE rule

A

= mutually exclusive, collectively exhaustive = there must be no overlap or gaps in any group of reasons/objections

1) mutually exclusive = within each group, the reasons/objections should be different from one another
2) collectively exhaustive = all conceivable arguments that are relevant to the claim are brought to bear, leaving no gaps in the argument tree
