Abstract

Levi in this book develops the views on inductive logic which he put forward in 1967 in Gambling with Truth. He extends the account given there of inductive expansion and supplements it with an account of routine expansion and contraction with the aim of constructing a view of how revisions of bodies of knowledge should be evaluated. He is concerned to give an account of the revision of probability judgments and gives the contexts of specific enquiries an important place in critical appraisal of changes in cognitive commitment.
