Georges Canguilhem's essay "L'Objet de l'histoire des sciences" ("The Object
of the History of Sciences") was delivered as a lecture to the Canadian
Society for the History and Philosophy of Science in Montreal on 28 October
1966 and first published two years later in *Études d'histoire et de
philosophie des sciences* (Paris: Vrin, 1968), pp. 9-23 — a dating given by
the anthology's own critical bibliography (compiled by Camille Limoges). A
section translated as "A History of Precursors," in the chapter "The History
of the History of Science" (*A Vital Rationalist: Selected Writings from Georges
Canguilhem*, ed. François Delaporte, trans. Arthur Goldhammer, Zone Books,
1994/2000), argues that treating an earlier figure as a precursor collapses
historical time into "the logical time of truth relations," producing what
Canguilhem names directly: "The result is the creation of an artifact, a
counterfeit historical object - the precursor." He defines the figure: "A
precursor, we are told, is a thinker or researcher who proceeded some
distance along a path later explored all the way to its end by someone
else."

Canguilhem's own cited lineage for this critique is entirely separate from
[[entity-herbert-butterfield|Butterfield's]]: he credits the diagnosis to the
American historian J.T. Clark's "precursor virus," invokes Alexandre Koyré's
parallel warning against the idea of a "forerunner" ("The notion of a
'forerunner' is a very dangerous one for the historian... no one has ever
regarded himself as the 'forerunner' of someone else"), and cites Louis
Dutens's 1776 *Recherches sur l'origine des découvertes attribuées aux
modernes* as an extreme case (crediting Hippocrates with knowing the
circulation of the blood). Across the three "Methodology" chapters read (pp.
25-55 of the translation), neither Butterfield, *The Whig Interpretation of
History*, nor the word "Whig" appears — a direct-reading finding scoped to
the chapters examined this session, not a claim about Canguilhem's whole
corpus.

This gives [[entity-precursorism|precursorism]] a second, textually
independent root: Canguilhem names and dates the same critique the vault
already has filed, via Wikipedia and [[entity-nick-jardine|Jardine]], under
[[claim-precursorism-is-named-and-classified-as-a-form-of-whig-history|Whig
history]] — but reaches it through Clark/Koyré/Dutens, not Butterfield. See
[[entity-georges-canguilhem]], [[entity-alexandre-koyre]],
[[moc-a-precursor-is-not-an-influence]]. Whether this independent strand is
also *earlier* than the Whig-history fusion is a separate question, addressed
in
[[claim-jardine-2003-dates-whig-fusion-to-1961-predating-canguilhem]] — the
answer there is no.
