Professor Neil Tennant has published his sixth book, which is entitled Changes of Mind: An Essay on Rational Belief Revision. Oxford University Press, which published the book in June, describes it as "the first logically precise, computationally implementable, book-length account of rational belief revision. It explains how a rational agent ought to proceed when adopting a new belief - a difficult matter if the new belief contradicts the agent's old beliefs."
