Which of Jevons's own logic texts supplies the 'p. 82'/'p. 83' conversion rules and the eight numbered 'rules of the syllogism' Aikins quotes in his 1902 Principles of Logic?
claim-aikins-1902-ch11-quotes-jevons-conversion-rules-verbatim-then-rejects-rule-following and claim-aikins-1902-ch16-footnote-quotes-jevons-eight-syllogism-rules-verbatim-then-rejects-them both rest, at Tier 1, on Aikins's own 1902 text quoting and citing Jevons by page number — that part is solid. What is not yet confirmed is which specific Jevons title and edition those page numbers (p. 82, p. 83, and the eight-rule list) belong to. The numbering and content strongly resemble Jevons's Elementary Lessons in Logic (1870), a widely reprinted textbook, but Jevons's own text was not fetched this session to check exact page correspondence.
What would resolve it: a direct read of a digitized Elementary Lessons in Logic (1870, or a later stereotyped reprint using the same pagination) at pp. 82–83 for the conversion rules and its syllogism-rules section for the eight-rule list, checked against Aikins's quoted wording and rule order. If the page numbers or wording don't match, the correct Jevons title/edition needs identifying (candidates: Elementary Lessons in Logic, The Principles of Science, Studies in Deductive Logic).
Why it matters: low-stakes for the claims already recorded (they describe what Aikins wrote, not what Jevons wrote), but load-bearing if a future note wants to compare Aikins's transcription against Jevons's original — e.g. to check for OCR drift, paraphrase, or a rule Aikins silently reworded.

Progress log
- 2026-10-01 — answered by claim-jevons-elementary-lessons-lesson-x-source-of-aikins-conversion-rule-citations, claim-jevons-elementary-lessons-lesson-xv-source-of-aikins-eight-syllogism-rules, and claim-jevons-elementary-lessons-1881-printing-toc-confirms-stable-pagination-since-1870. A direct read of Jevons's Elementary Lessons in Logic (1881 Macmillan 'New Edition', via Darwin Online) found Aikins's 'Jevons, p. 82'/'p. 83' and his eight numbered syllogism rules match, word for word and rule for rule, specific sentences in Lesson X (pp.81-87) and Lesson XV (pp.126-131) of that book, with the book's own table of contents independently confirming the pagination.
