 (Anscombe [1959, 108], Geach [1950, 474–5; 1975, 143–4] and Dummett [1973, 63–4] have all criticised Ramsey’s argument here on the grounds that whilst a predicate may be negated a name may not – although see Anscombe’s ‘Retractation’ [1965]. Coming from a different direction, Simons [1991, 159], Dokic and Engel [2002, 40–1] and Lowe [2004, 307] argue that Ramsey was mistaken to think that ontological issues could ever be settled in logico-linguistic terms. MacBride [2005a,b] argues that the former criticisms miss their intended mark because Ramsey was committed to denying that negative predicates correspond to the constituents of atomic facts; whereas the latter criticisms miss their mark because Ramsey was in fact arguing that logical reflection fails to determine the nature of the atomic facts. Hochberg [2004, 197–9], Mulligan [2000], Simons [1992, 151–2] raise further difficulties for Ramsey’s initial argument that builds upon the equivalence of (3.1) and (3.2) but MacBride [2018, 207–10] argues that these criticisms rest upon a failure to appreciate the radical character of Ramsey’s challenge.)
