Week 11: Week 11 — Argument I: Claim, Evidence, Warrant

1. Argument in rhetoric is not a quarrel but a structured attempt to persuade a specific audience through claims supported by evidence and connected by reasoning.
2. Stephen Toulmin's model identifies six components present in every real argument: claim, grounds, warrant, backing, qualifier, and rebuttal.
3. The claim is the central assertion the argument defends — it must be specific, debatable, and precise enough that someone could reasonably challenge it.
4. Grounds are the specific data, examples, and evidence offered in support of the claim. Without grounds, a claim is mere assertion.
5. The warrant is the unstated or stated assumption that makes the grounds relevant to the claim. It answers the question: why does this evidence support this claim?
6. Backing provides support for the warrant itself — when the warrant is contestable, backing establishes why the warrant should be accepted.
7. A qualifier acknowledges the conditions under which the claim holds — words like 'usually,' 'in most documented cases,' and 'with rare exceptions' make claims more defensible without weakening them.
8. Inductive reasoning moves from specific observations to a general conclusion. It produces probability, not certainty — a different sample might yield different results.
9. Deductive reasoning applies a general principle to a specific case. If the premises are true and the logic is valid, the conclusion follows necessarily.
10. The burden of proof falls on the party making the claim — they must provide sufficient grounds to support it. An extraordinary claim requires extraordinary evidence.
