"[This book] proposes new foundations for the Bayesian principle of rational action, and goes on to develop a new logic of desirability and probabtility."—Frederic Schick, Journal of Philosophy

Studies in Inductive Logic and Probability, Volume II—edited by Richard C. Jeffrey—delivers the long-awaited completion of Rudolf Carnap’s “Basic System of Inductive Logic” and, with it, a definitive bridge between logical probability and modern Bayesian thought. Opening with the posthumous Part II of Carnap’s program—on attribute spaces, confirmation across predicate families, and the celebrated λ–γ systems—the volume traces how exchangeability, similarity, and proximity reshape predictive inference beyond the straight rule. Jeffrey’s editorial apparatus situates Carnap’s late revisions and includes the originally withheld §21, offering a rare window onto the extensions Carnap envisaged but did not live to finish.Surrounding this keystone are landmark contributions that push the program into contemporary terrain. Hintikka and Niiniluoto secure positive confirmation for universal generalizations; Kuipers maps neighboring approaches; de Finetti’s classic paper on partial exchangeability (in translation) anchors the treatment of analogy across families; Link and Diaconis–Freedman supply modern representation theorems; Fenstad reconnects logical languages with probabilistic semantics; and David Lewis’s “Principal Principle” reweaves objective chance into subjective credence. Capped by Douglas Hoover’s note on nonstandard measures, the collection is both capstone and launchpad—indispensable for philosophers of science, statisticians, and decision theorists who want Carnap’s foundations rendered in the idiom that now governs rational belief and inductive learning.This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1980.

Rudolf Carnap and Richard C. Jeffrey’s Studies in Inductive Logic and Probability, Volume I gathers seminal work charting Carnap’s late-career re-architecture of inductive logic. Moving beyond the single preferred c\*-method of Logical Foundations of Probability (1950), this volume documents the shift to a “continuum” of c-functions and then to a still broader framework sensitive to analogy and similarity, informed by de Finetti’s representation theorem and contemporary probability/statistics. Anchored by Carnap’s “Basic System” (presented here in detail) and complemented by foundational essays—including the programmatic “Inductive Logic and Rational Decisions”—the collection recasts logical probability in the idiom of events, models, and conditionalization, aligning formal inductive methods with Bayesian decision theory while distinguishing logical from statistical notions of information and entropy.Framed by Jeffrey’s editorial introduction and Carnap’s own historical notes, the book doubles as an intellectual roadmap through the 1950s–60s renaissance in formal epistemology: collaborations with John Kemeny, dialogue with Savage and Putnam, and the systematic adoption of mathematical tools that were absent from Carnap’s earlier work. For philosophers of science, statisticians, and decision theorists, Volume I offers both a definitive statement of Carnap’s mature foundations and a launch pad for the unfinished upper stories—issues of confirmation, learning from analogy, and representation—that Volume II continues. It’s essential reading for anyone who wants to see how inductive logic became conversant with modern probability while retaining a distinctly logical—normative—conception of rational belief.This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact.

Computability and Logic has become a classic because of its accessibility to students without a mathematical background and because it covers not simply the staple topics of an intermediate logic course, such as Godel's incompleteness theorems, but also a large number of optional topics, from Turing's theory of computability to Ramsey's theorem. This 2007 fifth edition has been thoroughly revised by John Burgess. Including a selection of exercises, adjusted for this edition, at the end of each chapter, it offers a simpler treatment of the representability of recursive functions, a traditional stumbling block for students on the way to the Godel incompleteness theorems. This updated edition is also accompanied by a website as well as an instructor's manual.

Richard Jeffreys new book, From Grace To Verse, From Verse To Song, presents the Church with many new inspired hymns and hymn texts. They are artfully crafted and deeply rooted in the gospel message of our Lord, Jesus Christ. Im certain that many new arrangements of his hymns and musical settings of his hymn texts will emerge into the Church as a result of this book. I believe that Richard Jeffreys first published collection of original hymns will stand alone as a literary work. It will be embraced by the Christian community for many years to come. Those who wish to read this book purely for enjoyment and spiritual inspiration will not be disappointed.Sister Sally A. Daley QMWithout music, a hymn is just poetry and without words a hymn is just musical notes - - but marry the two elements and you create something wonderful that did not exist before. Jaroslav Vajda From grace to verse, from verse to song, may each new hymn tune now proclaim, with all the angels and the saints, the glory of your holy name. From grace to verse, from verse to song, the power of your Spirit flows through melodies that have the power to crush the might of heavens foes.Richard C. Jeffrey
