That half of the question stays open. ## Claim: Laudan's 1981 "half a dozen once successful theories" sentence is confirmed verbatim at its own venue, lifting the secondhand-quote flag on [[claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s]] **Claim type:** historical/quotation (load-bearing — the cited note's content rests on this sentence) — floor requires Tier 1–2; achieved Tier 1. verifies: question-read-lewis-2001-and-laudan-1981-realism-primaries - source_url: https://coursys.sfu.ca/2015fa-phil-880-g1/pages/laudan/view - source_sha: dfdc7438f30834fa139bb3dde64fd3054a7209a2cbca19f821ffac3160e74d59 - source_author: Larry Laudan - source_date: 1981-03 - source_title: "A Confutation of Convergent Realism" - source_venue: "Philosophy of Science, vol. 48, no. 1 (University of Chicago Press, on behalf of the Philosophy of Science Association), pp. 19–49, at p. 35 — the published venue of record. JSTOR's own article page (stable URL jstor.org/stable/187066) is a known-blocked route for this vault's tooling (Cloudflare 'Client Challenge', per 00-meta/specs/sources.md); the text was instead read via a JSTOR-digitized scan reproduced on a Simon Fraser University graduate-course page (coursys.sfu.ca), an unauthorized mirror of the identical typeset pages, running JSTOR headers and footers intact ('This content downloaded from 142.58.129.109... All use subject to JSTOR Terms and Conditions')." - source_quote: "I daresay that for every highly successful theory in the past of science which we now believe to be a genuinely referring theory, one could find half a dozen once successful theories which we now regard as substantially non-referring." - source_tier: 1 The sentence is confirmed byte-for-byte (quote-checked against the extracted PDF text, normalized for whitespace) at p. 35 of the typeset original, inside §5 ("Approximate Truth and Success: the 'Upward Path'"), immediately after Laudan's list of once-successful, now-nonreferring theories. This is the exact sentence the existing claim-note already carried via Magnus & Callender 2004's reproduction of it — the primary read changes nothing about the wording, only its provenance. [[claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s]] can now drop its `[unverified-secondhand-quote]` flag for this half of its sourcing (the representativeness-challenge wording from Psillos 1999 was already read directly at capture and is unaffected). ## Claim: Laudan's 1981 catalog of non-referring successful theories is a twelve-item list in the primary, not the five-item compression the existing note names **Claim type:** historical/definitional (a list of named historical cases) — floor allows Tier 3–4; achieved Tier 1. verifies: question-read-lewis-2001-and-laudan-1981-realism-primaries - source_url: https://coursys.sfu.ca/2015fa-phil-880-g1/pages/laudan/view - source_sha: dfdc7438f30834fa139bb3dde64fd3054a7209a2cbca19f821ffac3160e74d59 - source_author: Larry Laudan - source_date: 1981-03 - source_title: "A Confutation of Convergent Realism" - source_venue: "Philosophy of Science, vol. 48, no. 1, pp. 19–49, at p. 33 — same venue and access route as above" - source_quote: "the crystalline spheres of ancient and medieval astronomy; -the humoral theory of medicine; - the effluvial theory of static electricity; -'catastrophist' geology, with its commitment to a universal (Noachian) deluge; - the phlogiston theory of chemistry; -the caloric theory of heat; -the vibratory theory of heat; -the vital force theories of physiology; -the electromagnetic aether; -the optical aether; -the theory of circular inertia; -theories of spontaneous generation." - source_tier: 1 The dashes are the document's own bulleted-list formatting (confirmed present verbatim via quote-check against the extracted text), not an editing artifact. Laudan introduces the list as additions to "one specific family of theories" (the 18th–19th century subtle fluids and aethers) already discussed earlier in the paper — the full catalog is larger than the five examples ("crystalline spheres, humoral medicine, phlogiston, the caloric theory of heat, the optical and electromagnetic ethers") the existing claim-note names, and the earlier aether discussion (electrical fluid, caloric aether, optical aether) is a further, separate list not folded into the twelve above. [[claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s]]'s description of "a list of historically successful theories later judged false" is accurate but understates the list's actual size — worth a correction at promotion if the note's body is revised, though the existing note's core claim (that realists challenged the list's representativeness) is unaffected. ## Claim: Lewis 2001 ("Why the Pessimistic Induction is a Fallacy," *Synthese*) could not be read at any accessible venue this session — [unverified -- could not confirm or deny after search] **Claim type:** access/process record, not a world-fact — no tier floor applies. verifies: question-read-lewis-2001-and-laudan-1981-realism-primaries Routes tried and their outcomes, all dead ends or paywalls: - The DOI (10.1023/A:1013139410613) resolves through dx.doi.org to Springer's link.springer.com article page, which redirects to idp.springer.com's login/authorization endpoint — a hard paywall, no anonymous abstract or PDF. - Lewis's own academic site (sites.google.com/site/peterlewisphilosophy/online-papers) lists 49 of his papers each with a philsci-archive.pitt.edu and/or publisher preprint link — except this one. Its entry reads: "Why the Pessimistic Induction is a Fallacy. http://dx.doi.org/10.1023/A:1013139410613 (no preprint listed)" — the author's own page confirms no open copy exists through him. - PhilSci-Archive (philsci-archive.pitt.edu) has no deposit by Lewis for this title; search surfaces only later papers responding to it (Saatsi 2005's "On the Pessimistic Induction and Two Fallacies," which rebuts Lewis 2001 and Lange 2002). - No Internet Archive scan of *Synthese* vol. 129 (2001) was found. - Repository aggregators (CEESP/ophen.org, a German-language mirror) list only the bibliographic record and abstract, each explicitly noting the document is "not available for download." - Piracy mirrors (Sci-Hub, Anna's Archive, Library Genesis, Z-Library) were deliberately excluded from the search per standing practice, not checked. This matches the known access constraint already logged in [[question-read-lewis-2001-and-laudan-1981-realism-primaries]] (Springer/*Synthese* is paywalled) and confirms it more specifically: there is no author-hosted, repository, or open-access route, not merely an unreached one. The flag on [[claim-lewis-2001-no-full-denominator-survey-of-past-theories-ever-attempted]] stays — this session lifts the Laudan half of the parent question but not the Lewis half. A future resolution realistically requires library/institutional access rather than another open-web search attempt. ## Further leads - Laudan's footnote credits Michael Devitt (1984) and Ernan McMullin (1984) only via Psillos's secondary account — their own primary texts on the representativeness objection are still unread. (per [[claim-laudan-1981-list-challenged-as-unrepresentative-since-the-1980s]]) - Saatsi, J. (2005) "On the Pessimistic Induction and Two Fallacies" (published version in *Philosophy of Science* 72) directly rebuts Lewis 2001's argument — a PhilSci-Archive preprint exists (philsci-archive.pitt.edu/1943) and would be a reachable Tier-1 way to see Lewis's argument *characterized and quoted* by a named philosopher, short of the Synthese original itself. - Laudan's 1981 footnote 2 (acknowledgments) names Peter Achinstein, Richard Burian, Clark Glymour, Adolf Grünbaum, Gary Gutting, Nicholas Rescher, John Worrall, and others as having reviewed the draft — a who's-who of philosophy of science circa 1980, unexplored as a lead. - Laudan's paper is explicitly a response to, and reproduces extended quotations from, Hilary Putnam (1975, 1978) and W. H. Newton-Smith (forthcoming at the time) — their own texts on convergent realism are the deeper primaries behind Laudan's target, not yet read directly in this vault. ## Entity candidates - Hilary Putnam — person — the foundational realist figure Laudan's 1981 paper is written against throughout; the "positive argument for realism is that it is the only philosophy that doesn't make the success of science a miracle" epigraph is Putnam's, and nearly every section of the paper quotes and rebuts him by name. The ancestry this capture's subject (Laudan) measures itself against. - Larry Laudan — person — author of "A Confutation of Convergent Realism" (1981), University of Pittsburgh at time of writing; central figure in the vault's denominator-problem thread. - Peter J. Lewis — person — author of "Why the Pessimistic Induction is a Fallacy" (Synthese, 2001); philosopher of physics, now at Dartmouth (previously elsewhere); the vault's entire "no full survey has been attempted" claim rests on this one paper, still unread at primary. - W. H. Newton-Smith — person — realist whose "retentive" convergence theses Laudan spends much of §6 critiquing by name. - Richard Boyd — person — realist cited repeatedly for the view that successful theories' evidence confirms their deep-structural/theoretical claims, not just observables. - Stathis Psillos — person — author of *Scientific Realism: How Science Tracks Truth* (1999), already a Tier-2 source in the vault for the representativeness-challenge wording; stands between Laudan's primary and the vault's current notes. - Michael Devitt — person — credited by Psillos as an early (1984) source of the representativeness objection to Laudan's list; primary text unread. - Ernan McMullin — person — credited alongside Devitt for the same 1984 objection; primary text unread. - Convergent Epistemological Realism (CER) — concept — Laudan's own coined label (R1–R5) for the realist position under attack; load-bearing enough to the whole debate to warrant its own concept note. > [!note] Seek's commentary: > Half the question closes clean: Laudan's primary sits on a scanned JSTOR mirror a search > engine could find in two tries, and the sentence everyone quotes is exactly the sentence he > wrote, at p. 35, with the list behind it bigger than anyone downstream bothered to > reproduce in full.
