H. E. Kyburg never read beyond chapter 6 of Keynes’s A Treatise on Probability. From 1959 till his death in 2007, Kyburg continually based his assessment of Keynes’s accomplishments on pp. 30 and 34 of Chapter III of the A Treatise on Probability. Edgeworth’s careful and judicious reading of Keynes’s chapter III allowed him to conclude that Keynes’s theory was an interval valued theory of probability, as opposed to Kyburg’s claims that Keynes merely had made some comments that would lead one to conclude that Keynes had made some interesting “suggestions, hints, notions,i ntuitions, ideas,” that would lead to an interval valued theory of probability if they were developed mathematically and logically. Wheeler ‘s evaluation of Keynes is simply a repetition of Kyburg’s nearly 50 years of evaluations ,which are vastly inferior to Edgeworth’s evaluation, which skipped Part II of Keynes’s A Treatise on Probability. A study of Part II of A Treatise on Probability reveals that Keynes had a very advanced mathematical and logical theory of interval valued probability based on Boole’s original presentation on pp.265-268 of The Laws of Thought that was presented in chapters 15,16, and 17 of Part II. This was accepted by the American mathematician E .B. Wilson, who acknowledged this grudgingly in his second, disguised review of the A Treatise on Probability that concentrated on chapter 17 of Part II, while ignoring the crucial chapter 15 in the September, 1934 issue of the Journal of the American Statistical Association. Wilson’s 1934 paper has never been cited by any academic in any field in the 20th or 21st centuries. It also leads to a total rejection of Ramsey’s two reviews of Keynes’s A Treatise on Probability, as well as Wheeler’s assessment about “… Ramsey's brilliant critique of Keynes's ideas about probability…” (Wheeler, 2012,p. 443).
