Connection: Argument Structure ↔ Business Ethics

Ethical decision-making in business is, at its core, a reasoning problem. When a manager faces an ethical dilemma — a conflict of interest, a potential whistle-blower situation, a CSR trade-off — they construct an argument: “I should do X because of reasons Y and Z.” Whether that argument is sound determines whether the decision is genuinely ethical or just rationalized.

PHIL 252’s framework for evaluating arguments gives business ethics a rigorous backbone. An ethical decision isn’t just “what feels right” — it’s a conclusion that follows from acceptable, relevant, and sufficient premises.

From PHIL 252 — Argument Structure and Cogency

A cogent argument requires three things:

  1. Acceptable premises — the reasons given must themselves be credible
  2. Relevant premises — the reasons must actually bear on the conclusion
  3. Sufficient premises — the reasons must be strong enough to support the conclusion

An enthymeme is an argument with unstated premises. Much ethical rationalization works through hidden premises — “I deserve this bonus” implicitly assumes “people who work hard deserve financial rewards,” which is a premise that can and should be examined.

See Cogency and Enthymeme.

From ADMN 201 — Business Ethics

Business ethics are the individual standards that guide managers when rules don’t provide clear answers. Ethical failures often aren’t failures of knowledge — managers know insider trading is wrong — they’re failures of reasoning:

  • Motivated reasoning: building an argument backward from a desired conclusion
  • Rationalization: selecting only the premises that support what you already want to do
  • False relevance: citing irrelevant reasons to justify an action (“everyone does it”)
  • Insufficient grounds: concluding “this is acceptable” on the basis of “no one has complained yet”

All four are violations of cogency. A manager trained in argument evaluation is harder to rationalize past.

See BusinessEthics.

Why This Matters

Ethical Failure ModePHIL252 Diagnosis
”Everyone does it, so it’s fine”Appeal to common practice — irrelevant premise
”I’ll just do it once”Insufficient premise — frequency doesn’t change the ethical nature of the act
”They never explicitly said I couldn’t”Missing suppressed premise — acceptability ≠ ethical permissibility
”The benefits outweigh the costs”Requires evaluating whether the premise is acceptable — who counts as a stakeholder in the cost-benefit?

The most dangerous ethical arguments are cogent-looking but subtly flawed: the premises sound acceptable until examined closely.

Why Understanding Both Together Deepens Each

  • A PHIL 252 student who sees argument structure as purely abstract misses that ethics is its most consequential application domain.
  • A business ethics student who relies only on intuition has no method for diagnosing why a justification is wrong — they can feel it’s off but can’t argue back.

Together: the formal tools of argument evaluation give business ethics the precision it needs to be more than a feeling.
