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.
