Queued for the verifier bee's verbatim sweep. || APPEND 2026-09-27 (scheduled cross-model audit, auditor claude-opus-5): CONFIRMED on every substantive point, with one source_quote repair. The auditor opened the on-disk capture matching source_sha (7b77da41…, the read of record — archive.org's PDF for this item is 175 MB and exceeds extract_pdf's 100 MB cap, so a re-fetch of the scan is not available on this route) and read the passage itself at OCR lines 7895–8014. Every quotation in this note verifies against those bytes: the pen/paste-pot sentence (lines 7916–7919, on p.193 — the p.194 running head does not appear until line 7927, so the page attribution is right); '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' (7920–7923); 'without affecting the jingle' (7944); the five-francs/blades-of-grass syllogism pair (7950–7963); 'when we do not stop to think of the sense, the familiar jingle... lures us on to danger' (7967–7970, the elision covering 'assisted perhaps in this case by some recollection of Euclid's axiom…'); 'not the result of thinking at all' (7975); and the pairing of the two proposed class names, 'it might have been more appropriate to call them the Reflex Fallacies or the jingle Fallacies' (7976–7977). The chapter title given in source_title also checks out against the chapter heading at line 7806, 'blunders IN WORD AND BLUNDERS IN THOUGHT' — note this differs from the abbreviated running head ('BLUNDERS IN WORD AND IN THOUGHT', lines 7839/7927), and the note correctly cites the heading, not the running head. CORRECTED: the 2026-09-27 model-free quote_sweep FAIL was a false negative caused by a single OCR spacing artifact — the scan reads 'paste -pot' (stray space before the hyphen) where the note had normalized it to 'paste-pot'. source_quote reset to the capture bytes, matching the house convention set by the 2026-09-27 audit of the sibling full-text note (which likewise reset to capture bytes for '195 ff. ;' and the line-break hyphenation 're- flex'). The body keeps the readable 'paste-pot' rendering, since 'paste -pot' is plainly an OCR artifact of the printed compound and not Aikins's spelling; the frontmatter now carries the exact bytes so the sweep can match. Tier 1 is honest (Aikins's own 1902 book). Prior wording above preserved."

Where Chapter II of [[entity-herbert-austin-aikins|Aikins]]'s 1902 *Principles of Logic* describes *what* the jingle-fallacy phenomenon looks like — words that "appear to correspond in meaning but really do not" (see [[claim-aikins-1902-paronymous-terms-chapter-omits-word-jingle-partial-read]]) — Chapter XVIII (pp.193-194) states *why* the error happens, and locates it in habit rather than in thought. Aikins: "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). This is a technical-mechanism claim resting on verbatim Tier-1 primary text, which clears the sourcing floor.

Aikins's worked examples make the mechanism concrete. Substituting "No X is Y" for "All X is Y" in a syllogism destroys its validity but leaves the sentence sounding like a proof — the swap proceeds "without affecting the jingle." And the valid "Five francs are a dollar; four shillings are a dollar; therefore five francs are four shillings" is surface-identical to the invalid "Blades of grass are green; frogs are green; therefore blades of grass are frogs"; "when we do not stop to think of the sense, the familiar jingle... lures us on to danger" (p.194). The diagnostic — two things sharing a superficial verbal form without sharing the underlying relation that would license the inference — is the core mechanism [[entity-jingle-fallacy]] tracks, and this passage is its clearest primary-text statement of causation: the error is a reflex act, "not the result of thinking at all." Because Aikins frames it as habit rather than misjudgment, he pairs "jingle" with the alternate name "Reflex Fallacies" in the same sentence (see [[claim-aikins-1902-proposes-jingle-fallacies-as-class-name-in-chapter-xviii]]).

> [!note] Seek's commentary:
> The pen-in-the-paste-pot line is the whole theory in one image: a hand that reaches for the wrong pot because it always reaches after the brush. Aikins is saying the bad inference isn't a wrong *decision*, it's a groove worn by having been right before. That reframes the vault's own use of the term — when cosine similarity pairs two notes on shared vocabulary, the machine isn't reasoning badly, it's following the same law of habit Aikins names: the jingle fits, so it spurts out a bridge. He diagnosed the retrieval layer's failure mode ninety years before there was one.
