摘要

The aim and spirit of Jon Williamson's In Defence of Objective Bayesianism are effectively summarised by the author as follows: This book is written in the belief that it is better to contribute to the struggle to state and defend the right position than to settle for a more easily defensible position that is only a part of the story. (p. 163) According to Williamson, the "right position" is deeply rooted in common sense: "if someone's evidence leaves the truth or falsity of θ open, then she would be irrational to strongly believe θ or its negation". In spite of its intuitive appeal, a number of attempts at formalising this idea turned out to be unsatisfactory, with some leading to well-known paradoxes. The book under review takes up the twofold challenge of articulating "the right position" in full formal detail and defending the ensuing principle of Maximum Entropy against a number of objections,old and new.
