Consider the argument: 'All selfish actions are wrong. Voting out of personal interest is selfish. Therefore, voting out of personal interest is wrong.' This argument is deductively valid. What should a holistic evaluator do next?
AAccept the conclusion, since validity guarantees it follows from the premises
BReject the argument because the conclusion sounds counterintuitive
CAsk whether the first premise is well-supported and whether 'selfish' is being used consistently — validity alone does not establish the truth of premises
DSearch for a formal logical fallacy, since the conclusion must be wrong
Validity only guarantees that the conclusion follows *if the premises are true* — it says nothing about whether the premises are actually true. The first premise ('all selfish actions are wrong') is a substantive and contested claim that requires independent support. Holistic evaluation begins where formal validity analysis ends: are the premises plausible? Are key terms used consistently? A valid argument built on unsupported premises is not a good argument.
Question 2 Multiple Choice
Which best describes what holistic evaluation adds beyond checking an argument's formal logical structure?
AIt replaces logical analysis with intuition and emotional judgment
BIt asks whether premises are actually true and well-supported, whether they genuinely bear on the conclusion being argued, whether key considerations have been omitted, and how the argument fares against its strongest competition
CIt focuses on identifying the single weakest premise and dismissing the argument on that basis
DIt evaluates only the persuasive force of the conclusion, independent of the premises
Holistic evaluation is additive — it builds on formal analysis rather than replacing it. The four additional dimensions are: premise truth/plausibility (are they actually true?), relevance (do they genuinely support *this* conclusion?), completeness (what's missing?), and dialectical context (how does this argument compare to alternatives?). A holistic evaluator doesn't just look for flaws to dismiss — they aim at a fair overall verdict on how much rational weight the argument deserves.
Question 3 True / False
A deductively valid argument with a false premise can still establish its conclusion.
TTrue
FFalse
Answer: False
Validity tells you that *if the premises are true, the conclusion must be true* — it is a conditional guarantee. If a premise is false, the conditional's antecedent is not met, and the argument does not establish its conclusion. This is the difference between validity and soundness: a sound argument is valid *and* has true premises. Holistic evaluation must therefore assess premise truth, not just logical structure.
Question 4 True / False
An argument can be formally valid, have premises that are individually true, and still fail to establish its conclusion — because a true premise may be irrelevant to what the conclusion is actually about.
TTrue
FFalse
Answer: True
Relevance is a distinct evaluative dimension. A premise can be true and the inference valid, yet the premise may be tracking a neighboring question rather than the actual conclusion. For example, 'violent crime rates have fallen for decades' is true, but as a premise for 'this new policing policy is working,' it may be irrelevant if the policy was implemented last month. Holistic evaluation asks: does this evidence actually bear on *this* conclusion, or on some similar-sounding claim?
Question 5 Short Answer
What does it mean for a premise to be 'relevant' to a conclusion? Give an example of an argument where a true premise fails this relevance test.
Think about your answer, then reveal below.
Model answer: A premise is relevant to a conclusion when it provides genuine evidence for or against the specific claim being argued — when accepting or rejecting the premise actually changes how much we should believe the conclusion. A premise fails relevance when it addresses a neighboring claim rather than the conclusion at hand. Example: 'Exercise improves cardiovascular health [true]. Therefore, you should join this gym [conclusion].' The premise is true, but it doesn't bear on whether *this gym* is worth joining — it would support the conclusion equally whether the gym were excellent or a scam. The premise tracks the general value of exercise, not the specific question of gym membership.
The relevance test forces evaluators to ask: would this premise still be true if the conclusion were false? If yes, the premise may not be providing real evidence for the conclusion. This is especially important in arguments that shift the question — technically addressing one issue while the audience is debating another. Spotting irrelevance requires holding the conclusion clearly in mind and asking whether each premise is genuinely connected to it.
