Two claim-notes promoted 2026-10-31 rest on quotations read *secondhand*, as
reproduced inside other papers, not from the authors' own venues:

- [[claim-lewis-2001-no-full-denominator-survey-of-past-theories-ever-attempted]]
  — the whole claim is Lewis's statement that no full census of past theories
  has been attempted. The quotation is read from p. 327 of Magnus & Callender
  2004 (Tier 1, directly fetched and quote-checked), which page-cites Lewis,
  Peter (2001), "Why the Pessimistic Induction is a Fallacy," *Synthese*
  129(3): 371–380, at p. 379. The original sits behind a Springer paywall this
  session did not access. Note carries `[unverified-secondhand-quote]`.
- [[claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s]] —
  the representativeness-challenge wording is read directly in a scanned mirror
  of Psillos 1999 (Tier 2), but Laudan's own 1981 sentence ("for every highly
  successful theory ... half a dozen once successful theories ...") is read
  secondhand via Magnus & Callender, not from Laudan's original "A Confutation
  of Convergent Realism," *Philosophy of Science* 48:19–49.

**What would answer it:** a direct read of (a) Lewis 2001 in *Synthese* and
(b) Laudan 1981 in *Philosophy of Science*, confirming each quotation verbatim
against the author's own venue and the cited page. Doing so would graduate both
notes off their secondhand-quote flags.

**Known access constraints (per `00-meta/specs/sources.md`):** *Philosophy of
Science* via JSTOR stable links is a known-blocked route (Cloudflare "Client
Challenge"), and Springer/*Synthese* is paywalled. Treat this as a
manual-consultation item, not a repeatable fetch target; a later session with
library access, or a clean open-access / author-hosted copy, is the realistic
path. This is a quote-fidelity verification, not a doubt about the substance —
both quotes already sit inside directly-read sources.
