چکیده

Simon Saunders and David Wallace are attempting to use a modified form of David Lewis's analysis of personal fission to support the thought that prior to undergoing Everett branching an informed subject can be uncertain about which outcome s/he will observe. I argue that the seductive appeal of the idea is an illusion arising out of failure to distinguish between the provenance and reference of the relevant observers’ utterances.

1 Saunders and Wallace on Everett and Lewis Paul Tappenden 1 January 2008

Simon Saunders and David Wallace are attempting to use a modified form of David Lewis's analysis of personal fission to support the thought that prior to undergoing Everett branching an informed subject can be uncertain about which outcome s/he will observe. I argue that a central assumption of this seductive idea is questionable despite appearing innocuous and that at the very least further ar...

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 and Myrvold attempt to do without uncertainty altogether. Both these approaches are controversial and I suggest a middle way. I develop in detail an argument which Wallace has hinted at and Greaves has seen a...

Evidence and Uncertainty Everett ’ s Multiverse Paul Tappenden 1 12 December 2009

I endorse the view that it may be of no relevance to the acceptability of the Everett interpretation of quantum mechanics as a physical theory whether or not an informed observer can be uncertain about the outcome of a quantum measurement prior to its having occurred. However, I suggest that the very possibility of post-measurement, pre-observation uncertainty has an essential role to play in b...

Branching and Uncertainty

Following Lewis, it is widely held that branching worlds di¤er in important ways from diverging worlds. There is, however, a simple and natural semantics under which sentences uttered in branching worlds have much the same truth conditions as they do in diverging worlds. Under this semantics, whether branching or diverging, speakers cannot say in advance which branch or world is theirs. They ar...

Branching with Uncertain Semantics

In their paper ‘Branching and Uncertainty’, (Saunders and Wallace [2008]) aim to solve the so-called ‘incoherence problem’ commonly attributed to the Everett interpretation of quantum mechanics (EQM). The Everett interpretation posits a multiplicity of branching universes as a realistic reading of the evolution of the quantum state function. The ‘incoherence problem’ is, roughly, that our commo...
