Abstract

In philosophy, probability is often understood as a sentence operator. We argue that instead one should understand probability as a function symbol added to a language, and probabilities should be assigned to objects which represent sentences. Moreover we shall argue that this should be done in a type-free manner. We mention some features of our approach, for example that Lewis' Principal Principle is inconsistent in this framework, and we shall discuss a construction of a possible world style semantics for the probability function symbol.
