Keynes, A Treatise on Probability (Macmillan, 1921) originally appeared in The Cambridge Magazine. Volume XI No. 1 (January 1922). pp. 3–5. It was listed but not reprinted in the posthumous collection of Ramsey's work. The Foundations of Mathematics and other Logical Essays, edited by Professor R. B. Braithwaite. (Routledge & Kegan Paul. 1931) and later re-edited by me as Foundations: Essays in Philosophy, Logic, Mathematics and Economics (Routledge & Kegan Paul, 1978). I knew of it. therefore. but had never read it. thinking it would have been superseded by Ramsey's comments on Keyne's theory in his ‘Truth and probability’ (Foundations, ch. 3), until Professor Braithwaite gave me his copy of it last week. I then realized that it contained important comments not contained in ‘Truth and probability’, and agreed with Professor T. J. Smiley's suggestion that it should be republished. In preparing it for the printers I have corrected some clear typing errors. altered the quotation marks to conform to modern conventions, and removed some inconsistencies in punctuation and the capitalization of initial letters. I have also, for the benefit of Keynes‘ readers, restored his symbolism, which Ramsey varied: except that I have used the tilde instead of an overbar for negation. For those unfamiliar with it, ‘ϕ(a)/S(a). h’, for example, means, in what is now a more common notation. p(ϕa/Sa&h), that is. the probability that a is ϕp, given h and that a is S. I should also add that ‘g(ϕf)’ is how Keynes writes that all ϕs areϕs fs. —D. H. Mellor, Darwin College.
