The Emergent Multiverse is the most extensive, careful, and wide-ranging discussion of Hugh Everetts so-called Many Worlds interpretation of quantum theory in existence (at least on our branch of the multiverse), and is certain to become the locus classicus for all future discussions of the theory. Since the first obligation of a reviewer is to give guidance to potential readers, ... Read moreI will discharge that obligation first: if you have any interest in studying or trying to understand the Everett theory, you must get this book. You wont find a better discussion of both foundational issues and far-flung consequences of the theory anywhere. David Wallace has been brooding on the theory, and fielding objections to it, for over a decade. His considered views and responses are as careful and sophisticated as any on the market, and are equally attuned to physical and to philosophical issues.
Tim Maudlin, Nous
This book is an outstanding achievement. It presents the current state of the art in the Everett interpretation to a depth and level of sophistication that will be appreciated by the leading experts in the foundations of quantum theory (of whom Wallace is one)
and will educate them, and should chasten most of them. Yet, at the same time, the presentation is so clear and down-to-earth that this could serve as an introductory textbook for (say) undergraduates who are unfamiliar with any of the issues or even with quantum theory. This combination of relentlessly watertight argument with relentless common sense, however counter-intuitive the subject matter, is something Wallace is very good at. So much so that I think that even a philosophically-minded lay person, who would have to skip most of the technical discussion and equations, might nevertheless devour this book and learn a great deal from it

Nobody has done more to defend, clarify and advance the Everett interpretation over the past dozen years than Wallace, and this book is the culmination of his work on this area. As those who have read Wallace's articles will expect, it is an excellent book, and should be required reading for anyone interested in the foundations of quantum mechanics
Peter J. Lewis, Notre Dame Philosophical Reviews
The dialogic interludes are insightful and entertaining. The quotations at the beginning of each sectionare incredibly to the point...I recommend to everyone, especially to sceptics of the MWI to read this book: enjoy the brilliant and engaging style...
