A Critical Survey of Recent Contributions
Published online by Cambridge University Press: 14 March 2022
It is the purpose of this paper to review the present status of discussion concerning the concept of probability. The exposition will consist of six sections: (1) A brief statement of the most important traditional views of the concept of probability: subjective and objective; (a) A brief criticism of two traditionally important conceptions: a priori probability and the Principle of Indifference; (3) A criticism of an outstanding example of the subjective theory of probability, the theory of F. P. Ramsey; (4) A criticism of the most widely known of the objective logical theories of probability, the theory of J. M. Keynes; (5) Some remarks concerning the results of the recent work of Reichenbach and von Mises with particular reference to clarification of the concept of probability; (6) A summary of the case for the frequency interpretation of probability, revealing its basic importance in the light of present evidence.

9 This geometric interpretation is in terms of measure as found in mengenlehre. This definition has been developed by Waismann and Wittgenstein. Given a defined class A, the measure mA of this class is a surface segment. Given another class B, having at least one element in common with A, then the probability of the occurrence of an event of B is the ratio of the measure of the conjunction of A and B to the measure of A.
