All Probabilistic Methods Assume a Subjective Definition of Probability

"In previous publications on probability, I have followed I.J. Good in arguing that probability must be defined subjectively if we accept that the world is causally deterministic. In this article I go significantly beyond this position, arguing that we are forced to accept a subjective definition of probability if we use any probabilistic methods at all. In other words, all probabilistic methods tacitly assume a subjective definition of probability."
