Connection: Rhetorical Appeals ↔ Argument Structure

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 (ad populum / appeal to fear / etc.) — using emotional response as a substitute for evidence rather than as a supplement to it. When pathos replaces logos entirely, the argument lacks rational support.
  • Appeal to Authority (ad verecundiam) — citing an authority as proof rather than as evidence. Ethos supports credibility but does not replace a logical argument.
  • Red Herring / Distraction — emotional or irrelevant content that steers attention away from the actual argument’s merits.

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

    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:

  1. Use pathos to engage — but back it with logos
  2. Cite authorities to lend credibility — but also provide independent evidence
  3. Recognise these structures when reading others’ arguments (PHIL 252 lens)
