There are currently several versions of Everett's relative state interpretation of quantum mechanics, responding to a number of perceived problems for the original proposal. One of those problems is whether Everett's idea is in accord with the standard 'probabilistic' interpretation implicit in the Born rule. I argue in defence of what appears to be Everett's original view on this. The contribution I aim to make is a more complete discussion of the central issues of the identity of objects and… Expand
Identity and uncertainty in Everett's multiverse
In the current debate on the concept of probability in the Everett interpretation of quantum mechanics Saunders and Wallace argue for a notion of pre-measurement uncertainty whilst Greaves andExpand
Multiplicity in Everett's interpretation of quantum mechanics
It is concluded that much remains to be done to clarify and specify Everett's approach to quantum mechanics, as the spectrum of opinions on various ontological questions raised byverett's approach is rather large. Expand
Remarks on Space-Time and Locality in Everett’s Interpretation
Interpretations that follow Everett's idea that (at some level of description) the universal wave function contains a multiplicity of coexisting realities, usually claim to give a completely localExpand
Spacetime in Everett's interpretation of quantum mechanics
Everett's interpretation of quantum mechanics was proposed to avoid problems inherent in the prevailing interpretational frame. It assumes that quantum mechanics can be applied to any system and thatExpand
Worlds in the Everett interpretation
This is a discussion of how we can understand the world-view given to us by the Everett interpretation of quantum mechanics, and in particular the role played by the concept of `world'. The viewExpand
Objective probability and the mind-body relation
Abstract Objective probability in quantum mechanics is often thought to involve a stochastic process whereby an actual future is selected from a range of possibilities. Everett's seminal idea is thatExpand
The ins and outs of Schrödinger's cat box: a response to Papineau
The so-called many-worlds or many-minds interpretations of quantum mechancis, derived from the work of Hugh Everett III (1957), continue to have a very mixed reception among the well-informed, partlyExpand
Modal Metaphysics and the Everett Interpretation
Recent work on probability in the Everett interpretation of quantum mechanics yields a decision-theoretic derivation of David Lewis’ Principal Principle, and hence a general metaphysical theory ofExpand
Everett and structure
I address the problem of indefiniteness in quantum mechanics: the problem that the theory, without changes to its formalism, seems to predict that macroscopic quantities have no definite values. TheExpand
Some Worlds of Quantum Theory
Abstract: This paper assesses the Everettian approach to the measurement problem, especially the version of that approach advocated by Simon Saunders and David Wallace. I emphasise conceptual, indeedExpand


'Many Minds' Interpretations of Quantum Mechanics
Seventy years after the discovery of modern quantum mechanics, there is still no consensus as to how the theory should be understood. The philosophies of Niels Bohr and of the logical positivists,Expand
"Relative State" Formulation of Quantum Mechanics
The task of quantizing general relativity raises serious questions about the meaning of the present formulation and interpretation of quantum mechanics when applied to so fundamental a structure asExpand

Comment on Lockwood
Sociologists hardly need reminding that over the last three to four years there has been considerable debate in Britain about the future, or lack of it, of class analysis, much of it conducted in theExpand
