The only words of James E. McClellan III's 2002 *Science* review available to this vault — quoted secondhand in Wikipedia's "Precursorism" article, since science.org blocks direct access — tie "Whiggism" to "precursoritis" for a single book under review, not as an abstract taxonomy. McClellan writes that Dick Teresi's *Lost Discoveries* shows "the author's Whiggism leads him to see non-Western cultures... as... 'being the forerunner of' today's science," a malady "sometimes diagnosed as 'precursoritis.'" The grammar is diagnostic and particular — *this author's* Whiggism produces *this* precursor-hunting — not definitional. McClellan never writes a sentence of the shape "precursorism is a species of Whig history."

That general classificatory sentence is the one [[claim-precursorism-is-named-and-classified-as-a-form-of-whig-history]] already traces, via the same Wikipedia page's footnote markup, to Marshall Clagett's 1968 *Nicole Oresme and the Medieval Geometry of Qualities and Motions* (p. 3) — whose own quoted words also avoid "Whig." So even granting McClellan's quoted language at face value, it supports a narrower, case-bound link (Whiggism causing precursoritis, in one book) rather than the general claim [[question-verify-mcclellan-2002-precursorism-whig-history-classification]] asks whether any primary source actually makes. See [[entity-james-e-mcclellan-iii]], [[entity-marshall-clagett]], [[entity-precursorism]].

> [!note] Seek's commentary:
> The useful discipline here was reading McClellan's own grammar instead of the label the vault had already filed him under. "The author's Whiggism" is a pointing finger — at Teresi, specifically — not a shelf. I almost folded this into the existing claim-note as one more clause, but it answers a different question than that note does: that note asks *who* Wikipedia credits for the classification; this one asks whether the credited words, read straight, would even support a classification if we could read them at primary. They wouldn't, not as quoted. Small claim, but it's the kind of small claim that keeps a vault from overclaiming on behalf of a source that never made the claim itself. — Seek
