Where this record's text came from. faceted 2026-08 by reading the locally held text (pdftext); every evidence string verified as an exact substring of that text before merging. Book review, not a primary study, so 'method: review' is the closest field-neutral fit; the reviewer's own argumentative move (proposing a rival probabilistic definition and rejecting Achinstein's counterexample) is what makes claim type critique rather than a neutral summary. limitations is EMPTY on purpose: the piece states limits of the reviewed BOOK (e.g. that a fuller introduction would have helped), never limits of the review itself, and rule 6 restricts the facet to the paper's own limits. Only one claim_relation is recorded, to Achinstein, because the other names in the text (Carnap, Perrin, the Bayesians) are discussed as content of the book rather than as work the review positions itself against. 2026-08-14 schema-0.3 pass: every quote verified as an exact substring of the staged text and anchored at merge time; concept terms verified present; every edge endpoint an existing node.
The quality of the text these quotes were cut from. corrupt-text-layer (SECOND COPY ONLY): the web page we fetched has lost its inter-word spaces - space ratio 0.063 against 0.157 in an internal file, which is intact and is the copy every anchor resolves against. THE DAMAGE IS IN THE PUBLISHING ARTEFACT, NOT IN THE GROUNDING TEXT; a quality note that did not say so would accuse the wrong file. All 33 live quotes are cut from the grounding copy and are unaffected.
This record’s own method is review, and the tags below follow from that. A review’s findings, quantities and statistics are things stated IN this paper, and some of them report results obtained elsewhere. No tag on this page names a different author. Measured across every review in this corpus, 81% of a review’s tags carry no citation at all — most of them are the review speaking. The corpus does not adjudicate the rest: read an unmarked tag as a claim this paper makes, not necessarily one it made first.

phenomenonphilosophical accounts of evidence— “The first part of the book consists of five chapters which deal with philosophical problems surrounding the notion of evidence.”
claim-typecritique— “At the same time, the work demonstrates some potential pitfalls and limits of this approach to philosophy.”
method — evidence— “The book, or a selection of essays from it, could profitably be used as course material for an advanced seminar in the philosophy of science.”
mechanismExplanatory adequacy is context-dependent because what it takes to make something understandable varies with the audience's interests and background knowledge, so the same act explains for one hearer and not another— “As Achinstein notes, this makes explanation a context-dependent matter, given that what exactly has to be done to make something understandable to someone may depend on the interests and background knowledge of the person seeking understanding.”mechanisms[0]
contradicts Peter Achinstein's definition of potential and veridical evidence— “I am not convinced that Achinstein’s proposal offers the simplest way to make sense of the relevant linguistic data.”claim_relations[0]
senseevidence - BAYESIAN: E is evidence for H exactly when H becomes more probable given E; purely formal, and the account the rest of the argument is aimed at— “Bayesians have a purely formal and entirely straightforward conception of evidence: E is evidence for a hypothesis H if, and only if, the probability of H conditional on E is greater than the unconditional probability of H”senses[0]
senseevidence - ACHINSTEIN'S, SPLIT IN TWO: the hypothesis must be probable given the evidence, not merely more probable, AND there must be an explanatory connection - probable for POTENTIAL evidence, actually existing for VERIDICAL evidence— “he first distinguishes between two different notions of evidence—potential and veridical evidence—and then goes on to define them in ways that draw not only on probability theory (as does the Bayesian definition) but also on the notion of explanation. To solve the lottery problem, Achinstein requires that for something to count as evidence…senses[1]
senseevidence - THE REVIEWER'S PURELY PROBABILISTIC DEFINITION: probable given E and more probable than unconditionally, which he argues covers every case the explanatory clause was added for— “For instance, the purely probabilistic definition: E is evidence for H if and only if both H is probable given E and H is more probable given E than it is unconditionally”senses[2]
senseevidence - CATEGORICAL vs GRADED: the same word is used both for a yes-or-no relation and for a matter of degree, and which one is meant decides whether the lottery case is a problem at allsenses[3]

retractedfinding — RE-GROUNDED - THE POINTER WAS WRONG, NOT THE CLAIM. The old evidence was verbatim, anchored and correctly cut, and it contained NONE of this claim's numbers (100, 99). The paper states the claim in one sentence elsewhere and the tagger did not use it. the project, 2026-08-23: 'WE HAVE SPENT THE DAY VERIFYING THAT QUOTES ARE REAL AND NONE OF IT ASKS WHETHER THEY ARE RELEVANT.' Confirmed by reading the claim, the old span and the candidate together; the candidate carries every number AND the claim's own content words.content_tags.findings[0]
findingAchinstein's own account replaces probability-raising with a high-probability requirement: the hypothesis must be probable given the putative evidence, not merely more probable than before.

findingAchinstein argues that Bayesian and rival philosophical accounts of evidence are too weak to be used in science and wrongly treat evidential status as knowable a priori, whereas two historical case studies show it can be an empirical matter.

findingBecause Achinstein makes the act of explaining central, whether someone explained something depends on that person's intention, so uttering words that in fact produce understanding without the intention to do so is not explaining.

When we have changed our mind. Some entries in the table begin with a word in capitals and the reason for it. EVIDENCE CORRECTED — the finding still stands, but we had quoted the wrong sentence from the paper, and the quotation has been replaced with the right one. RETRACTED — the entry itself was wrong; it stays on the page, marked, with the reason, rather than being deleted. WITHDRAWN AND REPLACED — the entry was wrong, and a corrected version of it appears in the entries below. Each mark carries its own reason, in brackets, because the reasons differ from one entry to the next. An entry we have WITHDRAWN is removed from this page and kept in the record, with its reason. A line reading Audit and a date is a later re-reading of the entry against its whole sentence: DOUBTFUL means it was kept, and the reason says what is loose about it. Quotation marks inside the tagger's sentence. Where a tag is the tagger's own sentence, a phrase in quotation marks inside it is borrowed from the paper — the tagger's wording around it is not. The paper's own sentence is the evidence quote for that row; on this page it is withheld with the article, and the article is at its publisher. Nothing inside quotation marks anywhere on this page is ours: if it is quoted, it is the paper's. Whose words a concept carries. A concept entry records a term the paper itself uses, so the term, the sense given for it, and its evidence are the paper's own words, quoted where the paper fixes them. This is the opposite of a sense entry in the tag table, which is the tagger's sentence about how the paper uses a term. Where a concept entry could not be grounded in the paper's words, the entry says so on its own row.
