Abstract

This paper shows how Keynes provided a complete mathematical structure for his system of probability, which he called “approximation”, in the A Treatise on Probability, 1921.Keynes used the standard concept of conditional probability to duplicate many of Boole's problems. It is also demonstrated that he provided a solid mathematical structure for his non linear, non additive decision theory approach. We conclude that Keynes should be recognized as the founder of the modern non additive approach to probability.
