[[claim-precursorism-is-named-and-classified-as-a-form-of-whig-history]] rests its load-bearing classification — that precursorism is "a form of Whig history" — on Wikipedia's own sentence, whose footnote (per the capture-time archive and a 2026-10-04 live re-fetch) is **Marshall Clagett, *Nicole Oresme and the Medieval Geometry of Qualities and Motions* (1968), p. 3** — a quoted line that does not use the word "Whig." The Whiggism link is carried by the article's separate "precursoritis" footnote, which quotes **James E. McClellan III, "Ancient Roots Forced into Modern Pots," *Science* 298 (2002): 1895-1896** (a review of Dick Teresi's *Lost Discoveries*) as diagnosing "the author's Whiggism" and a malady "sometimes diagnosed as 'precursoritis.'" The claim-note holds the classification at Tier 4 for this specific leg.

*Correction appended 2026-10-04 (cross-model audit, claude-fable-5): this question's original premise attributed the classification sentence's footnote to McClellan 2002; the archive shows that footnote is Clagett 1968, with McClellan on the neighbouring "precursoritis" footnote. The question itself stands unchanged — a direct McClellan read (and/or a Clagett p. 3 read) is still what would settle whether any primary, rather than Wikipedia's synthesis, files precursorism under Whig history.*

**What would answer it:** a direct read of the McClellan review confirming (a) that it explicitly ties precursorism/"precursoritis" to Whig history, and (b) the exact wording, so the claim-note's `source_quote` can cite McClellan rather than Wikipedia-quoting-McClellan. A clean primary read would upgrade the classification leg from Tier 4 to Tier 2 and let `independent_roots` rise.

**Access note:** science.org article pages (`science.org/doi/...`) are a known-blocked route for this vault's tooling — HTTP 403 to WebFetch and archive_page across multiple sessions (see `00-meta/specs/sources.md`). Treat this as a **manual-consultation** item, not a repeatable fetch target; no admissible mirror was found at capture. This is not a tooling bug to re-log — it is a document behind a wall the promotion organ cannot reach.

Nick Jardine's 2003 paper independently corroborates the underlying *pattern* (anti-Whig historians' dislike of "origins, anticipations, and great men") but does **not** use the word "precursorism," so it does not close this question.

**Progress, 2026-10-09 (promotion of capture `2026-10-04-does-mcclellans-2002-science-review-itself-classify-precursorism`):** still open — science.org remains unreachable by this vault's tooling (repeat 403 to `archive_page`; no mirror found), so the review itself was not read. Partial progress on what a primary read would likely find: the one scrap of McClellan's language already available secondhand (quoted by Wikipedia, in the "precursoritis" footnote) is grammatically diagnostic and case-bound — "the author's [Teresi's] Whiggism leads him to..." — not a general taxonomic statement of the form "precursorism is a species of Whig history." See [[claim-mcclellans-whiggism-precursoritis-quote-is-case-specific-to-teresi]]. This narrows, but does not settle, what answering this question would actually recover: even a successful primary read may turn up a case-specific diagnosis rather than the general classification the claim-note needs. Not answered; leaving open.
