  "status": "source_checked",
  "scope": "Claim-level traceability review of the article and matching data record. Checked the traditional epistemological setup; Mill's argument-from-analogy formulation and attribution/date; objections and replies concerning single-case generalization and checkability; best-explanation, criteria/Wittgensteinian, perceptual, and testimony-based approaches; skeptical, conceptual, and metaphysical distinctions; and extensions to animals, infants, noncommunicating people, and machines. The status records traceability to the consulted passages, not the truth of any disputed philosophical conclusion, an exhaustive history or literature review, or expert review.",
  "summary": "The article now presents Mill's argument as an influential formulation rather than an origin claim; explains both the single-case objection and replies; distinguishes epistemological, conceptual, and metaphysical questions; and describes best-explanation, criteria-based, perceptual, and testimony-based alternatives without presenting them as settled. It separates uncertainty about knowledge from denial of other minds. Animal/infant applications are grounded in the SEP discussion; noncommunication and machine examples are explicitly labeled as editorial teaching extensions. Relevant passages of the SEP entry were read. Mill's own passage was verified through the SEP's quotation and citation, not by reading the primary text passage itself.",

Sections 1 and 1.1 describe the setup, cite Mill's 1865 formulation, and discuss the single-case, logical-checkability, and first-premise objections alongside replies. Sections 1.2–1.4.1 describe best explanation, criteria/Wittgensteinian approaches, and disputed perceptual accounts. Section 4.1 situates Mill in earlier debates and discusses Reid and an arguably earlier formulation in Arnauld.",

The entry explicitly reports disagreement about the problem and its solutions; its account is not treated as consensus or as establishing that any one argument succeeds.
