Book Description
The standard view of the economics profession is that Keynes was a brilliant, intuitive, nonrigorous innovator. These essays show that Keynes backed up his intuitions with a rigorous mathematical and logical supporting analysis, which has been overlooked.

Book Description
J M Keynes's A Treatise on Probability is built on the mathematical and logical foundations of G E Boole's 1854 The Laws of Thought. Boole introduced the first technical attempt (Adam Smith was the first to specify and solve two such indeterminate problems in The Wealth of Nations) at systematically solving indeterminate, probability problems (where, under uncertainty, relevant knowledge or evidence is missing) using interval valued probability. His systematic techniques were presented in chapters 16-21 of The Laws of Thought. Fisher's review of the A Treatise on Probability demonstrates an astounding degree of ignorance on his part. Fisher has no idea of what an indeterminate probability is. For Fisher, ALL probabilities MUST be point estimates. We will show that Fisher, a biologist wedded to the Limiting (Relative) Frequency interpretation of probability, had no idea about what Keynes was doing or talking about in Parts I-IV of the A Treatise on Probability. We will conclude that Fisher was foolish to attempt a review of the A Treatise on Probability knowing that he had not read Boole. This conclusion is then shown to apply to practically all modern, twentieth and twenty-first century writers on the A Treatise on Probability.

Book Description
C. D. Broad presents an excellent, overall view of how the A Treatise on Probability (1921) was written and constantly checked by internationally recognized and acclaimed philosophers and mathematical logicians, such as Bertrand Russell, Alfred North Whitehead, John Nevile Keynes, C. D. Broad himself, and especially William Ernest Johnson. Broad was the only reviewer to explicitly reveal the substantial role played by the applied mathematician and philosopher W. E. Johnson.Broad also carefully assessed Keynes's weight of the argument (evidence) criteria in Chapter 6 of the A Treatise on Probability, as did F. Y. Edgeworth. Neither of them found any errors.

Book Description
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).

Book Description
F. Y. Edgeworth made the only correct assessment of Keynes's Logical Theory of Probability in his A Treatise on Probability among philosophers in the 100 years between 1921 and 2020. The reason is that he actually read the entire book, with the exception of Part II, which he was able to assess through his very careful reading of Part I.The major problem confronting any philosopher, who wants to take into consideration the various different aspects of Keynes's A Treatise on Probability, is the unfortunate fact that there is no philosopher,with the one exception of Edgeworth (Bertrand Russell did not read Part V), who has read beyond chapters 1-4 plus some parts of chapter 6 of the A Treatise on Probability. This assessment includes every philosopher associated with SIPTA, as well as B. Koopman, I. J. Good, T. L. Fine, P. Suppes, H.E. Kyburg, I.Levi, S. Zabell, as well as younger philosophers, such as B. Weatherson, D. Rowbottom, R.Bradley, S. Bradley, J. Williamson, T. Siedenfeld, G. Wheeler, etc.The conclusion reached is that after 100 years there is only one sure path currently available to philosophers who want to know what it was that Keynes actually accomplished in the A Treatise on Probability-read and reread the two reviews made by Edgeworth. A reader is then in a good position to grasp what it was that Keynes had erected in 1921-the first mathematically and technically advanced interval valued approach to probability in history. Kyburg's claim, that he was the first to have put forth a detailed interval valued approach for a logical theory of probability, is simply a major oversight made by Kyburg.Edwin B. Wilson's conclusion, that Edgeworth was by the far the most qualified academic to review Keynes's A Treatise on Probability, still holds good 100 years after he published his reviews of Keynes's book.

Book Description
Arne Fisher attempted a cover up of an important footnote in chapter 29 of the A Treatise on Probability (1921), in which Keynes made it clear that he was not going to use the modern Method of Moments, which used a Moment Generating Function approach based on a Taylor Series expansion very similar to the Maclaurin Series, a special case of the Taylor series expansion, used by Keynes in chapter 17 of the A Treatise on Probability. Cumulants and semi-invariants, which A. Fisher claimed Keynes had no inkling of and did not understand, are simply terms used to describe particular parts of the Taylor series expansion carried out to provide the optimal estimate of a series using the Moment Generating Function technique. A. Fisher attempted to create the illusion that Keynes had made a number of very critical comments about the mathematical capabilities of Laplace, Bernoulli, and Poisson on pp. 358-361 of the A Treatise on Probability. These are figments of Fisher's own imagination. A. Fisher's “review” is really about one section of one chapter, chapter 29, sections 16-18, pp. 358-361, of the A Treatise on Probability. Nowhere in these pages will a reader find any such comments. A. Fisher, in his “review,” also sought to create the illusion that there were many mathematical errors in the A Treatise on Probability in these sections. In reality, there are no mathematical errors in these sections. Keynes simply used an older method of generating values for the Poisson distribution instead of using the most modern approach, the Method of Moments, which used the Moment Generating Function, with which Keynes was well acquainted with. A. Fisher gambled that no one reading his “review” would go back and check to see if his comments were correct. His gambit worked for nearly 94 years.

Book Description
Edgeworth's two reviews of the A Treatise on Probability, in Mind and The Journal of the Royal Statistical Society, demonstrated an understanding of many of the topics of Keynes' approach that was not achieved by any other reviewer, including the reviews made by B. Russell and C. D. Broad.Edgeworth covered and understood that interval valued probability was the most general representation of the probability relation for Keynes, that the weight of the evidence, was opposed to the weight of the argument, V, was an important breakthrough, along with Keynes' conventional coefficient of weight and risk, c.He recognized the connection between the "finite probabilities" of part III of the TP and interval valued probability, as well as the connection between them and Keynes' concepts of intuition, the logic of similarity-dissimilarity, resemblances, pattern recognition, and analogy. He understood the importance of being able to apply Chebyshev's Inequality in areas where Keynes had raised concerns about the effectiveness of the standard approach. Edgeworth's review is vastly superior to the reviews of Ronald Fisher and Arne Fisher, as well as to the reviews of E. Wilson, R. Pearl, or H. Jefferys.

Book Description
R. Pearl's attempt to review J M Keynes's A Treatise on Probability for Science is only a near fiasco compared with the failed attempt made by Ronald Fisher to review Keynes's book for the Eugenics Society. It provides the educated reader with minimal value. How this review made it through the referees, associate editors, and editors at the journal, Science, is a mystery worthy of investigation. Again, anyone attempting to read or review Keynes' A Treatise on Probability, without having any knowledge or familiarity of how J M Keynes made use in the A Treatise on Probability of George Boole's application of his logic to probability in chapters 16-21 of The Laws of Thought (1854), is foolish.
