We develop and defend the thesis that the Hilbert space formalism of quantum mechanics is a new theory of probability. The theory, like its classical counterpart, consists of an algebra of events, and...
Quantum Probability and Decision Theory, Revisited
Quantum Mechanics Everett Interpretation
2008/4/22
An extended analysis is given of the program, originally suggested by Deutsch, of solving the probability problem in the Everett interpretation by means of decision theory. Deutsch's own proof is disc...
Realism in the age of String Theory

2008/4/22
String theory currently is the only viable candidate for a unified description of all known natural forces. This article tries to demonstrate that the fundamental structural and methodological differe...
Explaining the Unobserved: Why Quantum Theory Ain't Only About Information
Quantum information Collapse theories Crucial experiments
2008/4/22
A remarkable theorem by Clifton, Bub and Halvorson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance...
Reality, measurement and locality in Quantum Field Theory
Quantum Field Theory Standard Model Correlations Locality
2008/4/22
It is currently believed that the local causality of Quantum Field
Theory (QFT) is destroyed by the measurement process. This belief
is also based on the Einstein-Podolsky-Rosen (EPR) paradox and on...
Relativity theory between structural and dynamical explanations
relativity spacetime explanation kinematics dynamics inertia
2008/4/22
In this review article I discuss Harvey Brown’s recent book Physical Relativity (OUP, 2005) by presenting and criticizing some of his main arguments in favour of a dynamical underpinning of rods contr...
What belongs to quantum theory is no more than what is needed for its derivation. Keeping to this maxim, we record a paradigmatic shift in the foundations of quantum mechanics, where the focus has rec...
SCIENTIFIC REALISM IN THE AGE OF STRING THEORY

2008/4/22
String theory currently is the only viable candidate for a unified description of all known natural forces. This article tries to demonstrate that the fundamental structural and methodological differe...
In this paper (which is, at best, a work in progress), I discuss different modes of scientific explanation
identified by philosophers
(Hempel, Salmon, Kitcher, Friedman, Hughes)
and
examine how w...
Sider's stage theory and expectancy prior to personal fission
Sider stage theory personal fission
2008/4/22
According to Sider’s stage theory a subject about to undergo personal fission should expect to experience each outcome simultaneously as distinct persons. How is the subject to make sense of this ? I ...
Simulation as an epistemic tool between theory and practice:A comparison of the relationship between theory and simulation in science and folk psychology
folk psychology
2008/4/21
In this paper I explore the concept of simulation that is employed by proponents of the so-called simulation theory within the debate about the nature and scientific status of folk psychology. Accordi...
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, indeed metaphysic...
Special Theory of Relativity and the Lorentz Force
Special Theory of Relativity Lorentz Trandformations
2008/4/21
Efforts to demonstrate that the application of Lorentz transformations leads to the form Y' = [Y - (v/c)N] (at least to the leading orders of approximation), which has been elevated to the criterion f...
String Theory - From Physics to Metaphysics

2008/4/21
Currently, string theory represents the only advanced approach to a unification of all interactions, including gravity. In spite of the more than thirty years of its existence, the sequence of metamor...
The Internal and External Problems of String Theory - A Philosophical View
String Theory Quantum Gravity Nomological Unification
2008/4/21
String theory is at the moment the only advanced approach to a unification of all interactions, including gravity. But, in spite of the more than thirty years of its existence, it does not make any em...
