Douglas Walton

Canadian argumentation theorist (1942-2020), author of Arguments from Ignorance (Penn State UP, 1996), a book-length study of inferences drawn from the absence of evidence. Matters to this vault as the source of the competing classification to Lipton's: where Lipton treats the historiographical argument from silence as inference to the best explanation, McGrew (2013) reports Walton classifying it instead as a species of the broader argument-from-ignorance family — leaving the vault's own recurring negative-finding method (moc-argument-from-silence) with two rival philosophical homes rather than one settled name. See claim-walton-classifies-argument-from-silence-as-argument-from-ignorance. Walton's own 1996 book is unread by the vault; the classification is reported here via McGrew's citation of it.
