  Ramsey was a pragmatist about belief (Hookway 2005, 182ff; Dokic and Engel 2002, 2, 8, 55), although not about truth. He explicitly declares his pragmatism in ‘Truth and Probability’ (1926a) and also in ‘Fact and Propositions’ (1927a). In ‘Truth and Probability’ he explains his approach to rationality as ‘a kind of pragmatism: we judge mental habits by whether they work’ (1926a, [PP] 93–94). In ‘Facts and Propositions’, in contrast, the issue is meaning: ‘The essence of pragmatism I take to be this, that the meaning of a sentence is to be determined by reference to the actions to which asserting it would lead’ (1927a, [PP] 51). He attributes his pragmatism about meaning to the influence of Bertrand Russell. In fact, in The Analysis of Mind (1921), Russell explained the intentional properties of words through their causal history. As Acero (2005, 16) stresses, for Russell at that time, the meaning of a word was its use, and it seems to be this aspect of Russell’s philosophy of mind that Ramsey acknowledges as the source of his pragmatism about meaning in ‘Facts and Propositions’ (cf. Dokic and Engel 2002, 22). Sahlin (1990, 70) and Hookway (2005, 185–187) point out that Peirce must also have had an effect on Ramsey’s pragmatist views, since many themes in Peirce’s early works are detectable in Ramsey’s writings (Hookway 2005, 185–6). Recently, Misak (2016a) has tracked Peirce’s influence on Ramsey in full detail, using the entries on Peirce that Ramsey inserted into his diary. It is now clear that Ramsey read Peirce extensively and that the American philosopher deeply influenced Ramsey’s views on meaning, truth and probability (Misak 2016a, 157).
