The main objective of this volume is to honor Sir Harold Jeffreys for the major theoretical and applied contributions he made to Bayesian analysis. Leading
experts in this field, S. Geisser, I. J. Good, and D. V. Lindley review and comment on these contributions to Bayesian inference, statistics, and the philosophy of science. E. T. Jaynes provides an analysis of and solution to the Dawid-Stone-Zidek marginalization paradox with discussion by A. P. Dawid, M. Stone, and J. V. Zidek. Other leading Bayesians have articles in the volume dealing with theoretical and applied topics in Bayesian analysis as well. Sir Harold's article, "Some General
Points in Probability Theory," was written and included especially for this volume.
