Objective Probabilities as a Guide to the World
Published: Philosophical Studies 95, 243-75, 1999
Abstract: According to principles of probability coordination, such as Miller's Principle or Lewis's Principal Principle, one ought to set one's subjective probability for an event equal to what one takes to be the objective probability of the event. For example, one should expect events with a very high probability to occur and those with a very low probability not to occur. This paper examines the grounds of such principles. It is argued that any attempt to justify a principle of probability coordination encounters the same difficulties as attempts to justify induction. As a result, no justification can be found.
