 Once back in Cambridge, Ramsey settled down to teach, including a course on the foundations of mathematics, and to write the papers in philosophy, economics and mathematics for which he was to become famous. He started by completing “The Foundations of Mathematics”, which he had begun in Vienna, and “Universals”, both published in 1925. The former was intended to rescue logicism by remedying the defects Ramsey found in Principia Mathematica, whilst the latter was a development of the programme of logical analysis advertised in the Tractatus; they won Ramsey immediate éclat. But it was the following year in which Ramsey really struck out on his own, writing “Truth and Probability” (1926a) although he did not publish it, which started from Ramsey’s criticisms of Keynes and provides a subjective theory of probability and a pragmatic view of induction, and “Facts and Propositions” (1927a), initially inspired by his reading of Peirce and Russell’s Analysis of Mind (1921), in which Ramsey’s philosophy of mind and language began to have, as he put it, a distinctive ‘pragmatist tendency’ (1927a, 170). It was also the year that Ramsey began dedicated work on economics which resulted in the first of his seminal papers on economics, ‘A contribution to the theory of taxation’ (1927b), later followed by his ‘Mathematical Theory of Saving’ (1928a). Ramsey also wrote his influential paper, ‘On a Problem of Formal Logic’ (1930), which contains the mathematical results now called ‘Ramsey’s Theorems’. In 1927 Ramsey also began work on a book manuscript, On Truth ([OT]). During the last two years of his life, Ramsey wrote a number of philosophical notes and papers, including ‘Theories’ and ‘General Propositions and Causality’, both completed in 1929. They were published by Braithwaite (in [FM]), along with ‘Truth and Probability’, in a posthumous volume of Ramsey’s papers, The Foundations of Mathematics and other Logical Essays, whilst the manuscript on truth did not appear until 1991.
