Does the word "jingle" appear anywhere in Aikins's 1902 Principles of Logic outside the read Ch. II passage?

question-verify-aikins-1902-full-text-for-word-jingle asked whether "jingle" appears anywhere in Aikins's 1902 Principles of Logic beyond the Chapter II "Paronymous terms" passage the vault had already read and found silent on the word (see claim-aikins-1902-paronymous-terms-chapter-omits-word-jingle-partial-read). This session fetched the full OCR text of the book — title page through back-of-book index, roughly 430 printed pages / ~19,000 lines of transcribed text — via archive_page against the Internet Archive's plaintext download (distinct from the /stream/ page URL the earlier partial-read note cited; same underlying scan, different URL and a different sha256 because it is the raw _djvu.txt file rather than a rendered HTML page) and read it start to finish in sequential chunks. The word "jingle" appears in exactly one place in the entire book, and it is not incidental.

Claim: "jingle" appears in Aikins's 1902 book outside Chapter II — in Chapter XVIII, where Aikins himself proposes naming a class of fallacies "the... jingle Fallacies"

Chapter XVIII, "Blunders in Word and Blunders in Thought" (pp. 193-194), discusses what Aikins calls "purely logical" fallacies — invalid syllogisms that nonetheless feel valid because their surface wording pattern-matches a valid form (e.g., substituting "No X" for "All X" without noticing the argument no longer holds). Illustrating with the reflex association "Adam, Eve, Cain" prompting people to misname Abel as Cain's killer, Aikins writes: "It is largely a mere matter of the verbal jingle, the answer resulting from the same law of habit in the nervous system that accounts for putting one's pen in the paste-pot after using the brush. Most of these so-called purely logical fallacies come in precisely the same way. Inference is in the air and the jingle seems to fit, so we spurt out something when the premises will not justify any inference whatever..." (p. 193). Two paragraphs later, discussing why such fallacies persist even when a term's sense secretly shifts mid-argument, he concludes: "In spite of a real confusion of meaning sometimes associated with some of these 'purely logical' fallacies they can hardly be called the result of bad thinking; because they are not the result of thinking at all, but only of a reflex act. On this account it might have been more appropriate to call them the Reflex Fallacies or the jingle Fallacies" (p. 194). This directly answers the question: yes, "jingle" appears outside Ch. II, and its one appearance in the book is Aikins proposing it, in his own words, as a name for an entire fallacy category.

Claim: the mechanism Aikins labels "jingle" is a reflex, habit-triggered inference from surface word-pattern, not a deliberate reasoning error

The passage is explicit about mechanism, not just terminology, and the quote is verbatim from the primary (Tier 1, clears the floor for a technical-mechanism claim). Aikins's own worked examples: substituting "No X is Y" for "All X is Y" in a syllogism destroys its validity, but "without affecting the jingle" — the sentence still sounds like a proof (p. 194). Likewise "Five francs are a dollar; four shillings are a dollar; therefore five francs are four shillings" is valid, but the surface-identical "Blades of grass are green; frogs are green; therefore blades of grass are frogs" is not — "when we do not stop to think of the sense, the familiar jingle... lures us on to danger" (p. 194). The diagnostic Aikins is describing — two things sharing a superficial verbal form without sharing the underlying relation that would license the inference — is the same core mechanism the vault's entity-jingle-fallacy hub already tracks; this passage is its clearest primary-text statement of why the error happens (habit/reflex, not reasoning), distinct from the Ch. II "Paronymous terms" passage's account of what the error looks like.

Claim: a complete pass of the book (title page through index, ~19,000 OCR lines) finds "jingle" in exactly one location, confirmed independently by Aikins's own index

verifies: question-verify-aikins-1902-full-text-for-word-jingle

Beyond the direct read, Aikins's own back-of-book index (p. 486) carries the entry "Fallacies, classification of, 191; jingle, 194; of forgotten issue, 195 ff.; of ill-conceived universe, 195; 'purely logical', 193; reflex, 194" — the author's own indexer treated "jingle" as a distinct, citable subentry under "Fallacies," pointing to the same page 194 found by direct read. No other occurrence of "jingle" was found anywhere else in the front matter, the 36 chapters, the exercises appendix, the index, or the publisher's catalogue pages at the back. This closes the scope gap explicitly flagged in claim-aikins-1902-paronymous-terms-chapter-omits-word-jingle-partial-read ([partial read — only Ch. II of ~430pp examined]): the book has now been read in full, and the word is not silent — it is concentrated in one deliberate, load-bearing passage that the Ch. II partial read simply had not reached yet.

Further leads

• claim-thorndike-1904-attributes-jingle-fallacy-to-aikins-not-himself quotes Thorndike (1904, p.14) crediting "Professor Aikins" with the term generically, without a page citation; this session's finding (pp. 193-194, Ch. XVIII) is a strong candidate for the exact passage Thorndike had in mind, though Thorndike's own text does not cite a page and this is inference, not confirmed correspondence.
• A future promotion pass might reconsider whether entity-jingle-fallacy's primary citation to Aikins should point to Ch. XVIII pp. 193-194 (where the word and the proposed name actually appear) rather than, or in addition to, Ch. II (which argues the matching concept but never uses the word).
• Aikins's paired alternate name, "the Reflex Fallacies," ties the phenomenon explicitly to habit/nervous-system psychology elsewhere in his own book (Ch. XXII, on how uniform reactions are formed) — unexplored connection, not read closely this session.
• Kelley (1927), Interpretation of Educational Measurements, pp. 63-64 — still unread by the vault per the routed question's lower-priority item; would cross-check whether Kelley's own "jangle fallacy" coinage passage also engages Aikins's original wording.

Entity candidates

• Herbert Austin Aikins — person — already entity-herbert-austin-aikins; update candidate — this passage is where Aikins himself writes and proposes the word "jingle" as a fallacy-class name, strengthening (beyond Thorndike's secondhand credit) his status as the term's textual origin point.
• William Stanley Jevons — person — the older, foundational logic-textbook author ("Elementary Lessons in Logic," "Studies in Deductive Logic") whose stated rules of the syllogism Aikins is directly working against in this same chapter and the surrounding ones (e.g., the "conversion by negation" and syllogism-rule material Aikins repeatedly quotes and revises); not currently an entity in this vault, and the figure this specific fallacy chapter measures its own account against.
• "Reflex Fallacies" — concept/term — Aikins's own paired alternate name for "the jingle Fallacies," proposed in the identical sentence (p. 194); not currently in the vault, and a candidate bridge to habit-psychology material elsewhere in the same book.

Safety flags

None. The only source read this session was the Internet Archive's plaintext scan of a 1902 public-domain logic textbook — ordinary OCR'd book text throughout (including its own exercises, index, and publisher's catalogue), with no addressed-to-AI language, override language, claimed authority, tier self-assignment, file-system instructions, credential requests, or urgency framing anywhere in the ~19,000 lines read.
