Works by and about Richard Jeffrey

Richard C. Jeffrey, tireless champion of (subjective) probability as "the very guide to life," taught philosophy at Princeton from 1974 until his retirement in 1999. This site collects Prof. Jeffrey's papers along with relevant work by friends and fellow travellers. The University of Pittsburgh hosts the Richard C. Jeffrey Papers archive with numerous manuscripts available online.

Brief Autobiography

Teenage logical positivism led me to Chicago for an MA with Carnap and, years later, to Princeton for a PhD with Hempel. My "radical probabilism'" grew out of that; see Probability and the Art of Judgment (1992). So did an earlier collaboration with Carnap; see Studies in Inductive Logic and Probability (1971, 1980). The Logic of Decision (1965, 1983, 1990) was the product of long labor (1960–4) followed by merciful midwifery (1964) of Bolker and Gödel. Formal Logic: Its Scope and Limits (1967, 1981, 1991) was inspired when Raymond Smullyan cleared up Evert Beth's "tableau" method for me, one day, on the street in New York. The "logic" half of Computability and Logic (1974, 1980, 1989) came into being when George Boolos joined in. By the 3rd edition that half had grown to two thirds. When George died in 1996 I edited his Logic, Logic, and Logic (1999) — with an extensive introduction by John Burgess. And when Hempel died in 1997 I edited his Selected Philosophical Essays (2000). I miss them sorely.
