Argument Analysis Procedure

The argument analysis procedure is a systematic, three-step method for evaluating extended arguments — particularly those found in everyday writing, speeches, and media. It applies the course’s theoretical tools (cogency conditions, fallacy categories, dialectical acceptability) to real, messy arguments.

How It Appears Per Course

PHIL 252

Chapter 20 capstone. The procedure is the practical integration of every tool covered in the course. It is what you use in the final project when analyzing a real media argument.

The Three Steps

Step 1 — Identify, Clarify, Distinguish

Clearly identify all the claims being put forward, clarify their meaning, and distinguish the conclusion from the premises.

• Use indicator words (therefore, because, since, thus) to locate the conclusion
• What is presented as the conclusion and what is actually argued for may differ (e.g., irrelevant thesis)
• Watch for lexical ambiguity and emotionally loaded premises
• If implicit premises exist, make them explicit
• Output: the argument in standard form

Step 2 — Evaluate Dialectical Acceptability

Analyze whether the premises are dialectically acceptable and relevant to the conclusion.

Premises must be:

• True or rationally likely (not circular, not ambiguous, not simply assumed)
• Dialectically acceptable: standing up to scrutiny by a reasonable, general audience — not just a specific group’s feelings
• Relevant to the conclusion (not appeal to emotion, not irrelevant thesis)

If the argument is circular, premises cannot offer rational support even when true. If premises appeal to emotion rather than reason, they fail dialectical acceptability regardless of their emotional force.

Step 3 — Evaluate the Logical Connection

Evaluate the logical connection between the premises and conclusion, looking for patterns such as fallacies.

Even if premises are acceptable, do they give sufficient rational grounds for the conclusion? Use fallacy categories as a diagnostic checklist:

• Expertise fallacies (Ch. 16): Is the connection legitimate authority, or just an appeal to status?
• Inductive/causal fallacies (Ch. 17): Is the causal claim adequately supported?
• Emotional bias fallacies (Ch. 15): Is the connection based on reason or on making you feel a certain way?

Cogency Conditions (Review)

An argument is cogent when all three conditions are met:

1. Premises are accepted or rationally acceptable to a reasonable audience
2. Premises make a rationally grounded connection to the conclusion (the truth of the premises genuinely bears on the truth of the conclusion)
3. Premises provide sufficient or strong rational grounds for the conclusion

Fallacies fail at one or more of these three conditions.

Walton’s Five Conditions for Fallacies

A fallacy is:

1. An argument (or at least something that purports to be an argument)
2. That falls short of some standard of correctness
3. Used in a context of dialogue
4. Has a semblance of correctness about it ← why they are dangerous
5. Poses a serious problem to the realization of the goal of the dialogue

Applied Example: St. Albert Gazette Letter

A letter arguing against senior funding cuts illustrates how to apply the procedure (Dayton & Rodier, pp. 290–94):

Claim	Identified Fallacy
Council “lacks common sense”	Abuse (ad hominem)
“Discussions with seniors”	Appeal to anonymous authority
Father was a political powerhouse	Equivocation (influence ≠ expertise) + anonymous authority
”Vote you out!”	Appeal to force + implicit Bifurcation
Traffic circle (2015) → senior cuts (2023)	Irrelevant thesis

The charitable reconstruction (Step 3 done right): A cogent argument can be built for the same conclusion using material inferences about the purpose of taxation and the distinct needs of seniors — showing the goal is valid even when the original argument is not.

Taking Cognitive Ownership

Critical thinking is not just following rules — it is exercising judgment and taking responsibility for evaluations made. Specifically:

• Be charitable: don’t dismiss arguments as cranky — take them seriously as claims for reasonableness
• Identify the strongest version of a fallacy, not just any version
• Ask: is there anything good in this argument? Can some parts survive?
• Recognize that evaluating an argument means taking it on as your own

Cross-Course Connections

Cogency — the three cogency conditions are the scaffold for Steps 2 and 3
MaterialInferences — Step 1 makes implicit material inferences explicit
FairCharacterization — charitable interpretation is built into Steps 1 and 3
CriticalThinking — this procedure is the operational application of critical thinking
ProfessionalEthics — the Potter Process (ADMN233) is a structurally similar four-step evaluation

Key Points for Exam/Study

• Three steps: (1) Identify/Clarify/Distinguish → (2) Dialectical Acceptability → (3) Logical Connection
• Step 2 tests PREMISES; Step 3 tests the CONNECTION between premises and conclusion
• Cogency = three conditions (acceptable premises + grounded connection + sufficient grounds)
• Walton’s 5 conditions define fallacies — the “semblance of correctness” is why fallacies are persuasive
• Fallacies are symptoms of bad reasoning — identify the strongest one, not just any
