After its publication in 1967, The Foundations of Scientific Inference  taught a generation of students and researchers about the problem of  induction, the interpretation of probability, and confirmation theory.  Fifty years later, Wesley C. Salmon’s book remains one of the clearest  introductions to these fundamental problems in the philosophy of  science. This anniversary edition of Salmon’s foundational work features  a detailed introduction by Christopher Hitchcock, which examines the  book’s origins, influences, and major themes, its impact and enduring  effects, the disputes it raised, and its place in current studies,  revisiting Salmon’s ideas for a new audience of philosophers,  historians, scientists, and students.
