Nearly one hundred years after Keynes published his A Treatise on Probability in 1921,it appears that practically no philosophers have read Part II of the A Treatise on Probability in either the 20th or 21st centuries. This simply means that no modern day philosopher is in any position to...

J M Keynes's two logical relations of rational degree of probability, α, 0≤α≤1 and Evidential Weight of the Argument, w, 0≤w≤1, where w measures the degree of completeness of the evidence, can't be represented or associated with ordinal probability, although Keynes's theory of...

A major error in analyzing how Keynes operationalized his logical theory of probability in 1921 is to assume that Keynes's theoretical structure is presented by him at the end of Chapter III of the A Treatise on Probability on pp. 38-40, which contains a diagram on page 39 that Keynes himself...

There was a major change in both the tone and claims made about the scientific quality of Keynes's treatment of probability in the A Treatise on Probability in Ramsey's second review of the A Treatise on Probability in 1926 when compared to the earlier 1921 review. The tone became much more...
