Argumentation & Rhetorical Devices

← Back to Domain-Specific Families

Abstractions that name figures, fallacies, and moves within argument and rhetoric — rhetorical figures (antithesis, litotes, rhetorical question), informal fallacies that misdirect a dispute (false equivalence, tu quoque, special pleading, motte-and-bailey), and strategic argumentative postures such as concession, if-by-whiskey and rhetorical listening.

22 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Antithesis — Sharpen a contrast by fusing two primitives — parallel grammatical form and opposed content — so a matched syntactic frame delivers the opposition at a controlled, audible beat.
• Complex Question — Expose a question that smuggles a contested claim in as its presupposition, so every direct answer silently ratifies the claim and the only sound reply is to refuse the frame.
• Concession — Grant a peripheral or indefensible part of the opposing case while continuing to contest the rest, purchasing credibility through costly-looking admission and, if the granted claim was not load-bearing, harvesting narrowing, burden-shift, and board-clearing at once.
• Context Collapse — The communication condition in which multiple audiences with irreconcilable norms are co-present in one channel, so a single utterance cannot satisfy all at once — a structural failure of the channel, not the speaker's judgment.
• Fallacy of Four Terms — A purported categorical syllogism in which two premises contain four effective terms rather than one shared middle term and two extremes, so the conclusion's extremes are not inferentially linked.
• False Equivalence — The fallacy of treating two things as comparably weighted on the dimension a judgment turns on, when they in fact differ by an order of magnitude or by kind — by highlighting a genuine shared feature and suppressing the difference that actually controls.
• Hurford Disjunction — A natural-language disjunction whose alternatives stand in an entailment relation, creating a potential redundancy puzzle.
• If-by-Whiskey — Take no real position on a contested issue by splitting its loaded term into two opposite-valence conditionals, asserting an unobjectionable stance on each and indexing neither to the actual case — so every audience hears what it wants while the speaker commits to nothing.
• Irrelevant conclusion — Prove a sound argument for a proposition that is not the one at issue, then treat it as settling the contested claim — a relevance failure caught by restating the question before grading the answer.
• Kettle logic — A defensive pattern in which an arguer offers several mutually contradictory defenses at once — each sufficient alone but jointly self-undermining — so the scatter is itself evidence that none is relied upon and the aim is deflection by volume, not vindication.
• Label Ambiguity — Diagnose a headline accuracy figure as a blend of two measurements — model capability in the class interior where annotators agree, and mere adjudication agreement in the boundary zone where reasonable experts split — by stratifying metrics on the inter-annotator agreement rate.
• Litotes — Assert something by negating its contrary — 'not bad' for good, 'no small feat' for a substantial achievement — so the gap between the stated-weak negation and the conveyed-strong meaning does the work, typically intensifying under a culturally trained convention the audience must share.
• Motte-and-bailey fallacy — Maintain a strong controversial claim and a weak defensible one under the same label, advancing the strong claim when unchallenged but retreating to the weak one under fire and resuming the strong claim once the challenge passes — so the motte's successful defence is misread as vindicating the bailey.
• Okrent's Law — The pursuit of journalistic balance can create imbalance, because equal procedural treatment of unequal evidence presses belief toward the weaker side by a margin that grows with the evidence gap — a thumb on the scale, not its absence.
• Performative Contradiction — Expose a conflict between what an utterance asserts and a condition its very performance pragmatically presupposes.
• Relative Privation — The informal fallacy of dismissing a concern by pointing to a worse problem elsewhere, conflating severity-ranking with action-licensing — since ranking governs how much total attention a problem warrants, not whether it is eligible for any, unless the worse problem's resources are genuinely exclusive.
• Review — A structured evaluative artifact linking four slots — an identified evaluator, a bounded object under evaluation, a verdict, and a warrant — into a persisted, addressable record, so evaluative testimony becomes aggregable, citable, and revisable.
• Rhetorical Listening — Suspend rebuttal and parse another's discourse through three moves — what they claim as their stakes, what genuinely remains contested, and what your own position lets you hear — so an accurate hearing and a firm 'no' become compatible.
• Rhetorical Question — Use interrogative form to perform an assertion rather than seek information, leaving the answer for the audience to supply internally so their self-generated agreement does the persuading — a move whose success rides entirely on an accurate audience model.
• Special Pleading — The fallacy of exempting a favored case from a general standard the arguer just invoked, without a principled basis — a consistency violation under self-serving direction, exposed by asking whether the arguer would grant the same exception to an opponent.
• The Saying and the Said — A Levinasian distinction between language as pre-propositional ethical exposure to another and language as the necessary thematic content that identifies, communicates, and can also totalize.
• Tu Quoque — Catch the fallacy of rebutting a charge by alleging the accuser commits the same offence — substituting a verdict on the speaker's standing for a verdict on the speaker's claim — by asking whether the dispute was about a proposition's truth or the speaker's standing.
