Abstract

A clear, careful, thoughtful, critical survey introducing a wide range of ideas about many worlds and related interpretations. The book is particularly suited to those with some knowledge of quantum mechanics who prefer words to equations. At first sight, much of Barrett's concern is with theories which are clearly implausible, such as the “bare theory” or “Bell's Everett (?) theory”, but Barrett uses these theories skilfully as simple examples elucidating issues of wider significance. The book includes a detailed reading of Everett's own work and a non technical analysis of the Bohm interpretation
