Connection: Rhetorical Appeals ↔ Argument Structure
The Link
Both ADMN 233 and PHIL 252 trace back to Aristotle, but from different directions. ADMN 233 asks: how do I use pathos, logos, and ethos to persuade? PHIL 252 asks: when does an appeal to emotion or authority become a fallacy? The same three appeals are the subject — one course teaches you to use them, the other teaches you to evaluate them critically.
From ADMN 233
The three rhetorical appeals are tools for constructing effective persuasive messages:
- Pathos (emotion) — the fastest way to get attention; leads the hook and introduction
- Logos (logic) — facts, data, expert opinion — supports the explanation and evidence sections
- Ethos (credibility) — established through expertise, qualifications, and presentation quality
The course recommends balancing all three: lead with pathos, establish ethos, support with logos. Over-reliance on any single appeal weakens the message.
From PHIL 252
PHIL 252 treats arguments as structures with premises and conclusions. Emotional and authority-based appeals are examined as potential informal fallacies:
- Appeal to Emotion — using emotional response as a substitute for evidence rather than as a supplement to it. Unit 9 (Ch.15) names the specific fallacious forms of pathos:
- Mob appeal (argumentum ad populum) — swaying belief via group identity, theatrical language, or special interests
- Appeal to pity (argumentum ad misericordiam) — evoking sympathy to cause assent to a claim
- Appeal to force or fear (argumentum ad baculum) — using threats to force acceptance of a conclusion
- Two wrongs make a right — justifying behaviour by claiming the other person would do the same
- Appeal to Authority (ad verecundiam) — citing an authority as proof rather than as evidence. Ethos supports credibility but does not replace a logical argument. (Unit 8 covers the specific fallacies of expertise: snob appeal, appeal to tradition, appeal to nature, appeal to ignorance.)
- Ad Hominem — attacking the person rather than the argument is a misuse of ethos: instead of building credibility, it tears down the opponent’s. Three forms: abuse, poisoning the well, tu quoque (all Ch.15).
- Red Herring / Distraction — emotional or irrelevant content that steers attention away from the actual argument’s merits. (Unit 7, covered in FalseCause.)
The key distinction: in PHIL 252, these appeals are fallacies when they substitute for reasoning. In ADMN 233, they are legitimate tools when they supplement sound reasoning.
Why This Matters
graph TD A[Aristotle's Rhetorical Appeals] --> B[ADMN 233 — Persuasive Communication] A --> C[PHIL 252 — Critical Thinking / Argument Analysis] B --> B1["Use all three to craft\neffective messages"] C --> C1["Identify when appeals\nreplace vs. support logic"] B1 --> D["Pathos hooks, logos convinces,\nethos lends credibility"] C1 --> E["Fallacy = appeal used as\nsubstitute for evidence"] D --> F[Stronger professional communication] E --> F
The same move can be legitimate persuasion or a logical fallacy depending on whether evidence is present. An effective professional communicator (ADMN 233 goal) should:
- Use pathos to engage — but back it with logos
- Cite authorities to lend credibility — but also provide independent evidence
- Recognise these structures when reading others’ arguments (PHIL 252 lens)
