J.M. Keynes’s method in the A Treatise on Probability, inexact measurement and approximation using non additive upper and lower probabilities, is a formal, inductive logic built on G. Boole’s original Boolean Algebra and Logic. It has nothing to do with "…a given list of possible behaviors. ” (Almeida, no date). Keynes’s approach uses intuition, induction, pattern recognition and analogy as a foundation, using different degrees of similarity and dissimilarity connecting the past to the future, to analyze and solve existing problems with major future implications. The researcher, using Keynesian induction and intuition, is able to discover relevant connections from the past that may very likely play a deciding role in unsolved problems extending and dealing with the future. A researcher does not create a solution out of nothing based on his imagining things about the future whimsically when he is daydreaming or sleeping and having dreams.
