Towards a Unified Concept of Probability

Publisher Summary The main line of division of probability is between the concepts of subjective and objective probability. The chapter argues for a conception according to which subjective and objective probabilities derive from one prototypal concept. The chapter discusses the objective aspects of subjective probabilities. The strongest claim to objectivity is made in the non-deterministic framework of quantum physics, where the expected change is 0. The chapter discusses the usage of inner stability or, for short, stability, as a measure that increases as the expected change decreases. The chapter discusses internal and external change. Randomness properties are also discussed in the chapter.
