Hypothetical frequencies as approximations
Hypothetical frequencies are great approximations (inexact descriptions of a target) but bad idealizations (separate models that bear analogies to the target).
Classical limits of Hilbert bimodules as symplectic dual pairs
Hilbert bimodules are morphisms between C*-algebraic models of quantum systems, while symplectic dual pairs are morphisms between Poisson geometric models of classical systems. …
An accuracy-based approach to quantum conditionalization
A core tenet of Bayesian epistemology is that rational agents update by conditionalization. Accuracy arguments in favour of this norm are well-known. Meanwhile, scholars working in …
One world is (probably) just as good as many
I argue that we can use symmetries of the quantum state space to derive chance values in the de Broglie–Bohm pilot-wave theory.
Two Forms of Inconsistency in Quantum Foundations
Recently, there has been some discussion of how Dutch Book arguments might be used to demonstrate the rational incoherence of certain hidden variable models of quantum theory. In …
Extensions of bundles of C*-algebras
Bundles of C*-algebras can be used to represent limits of physical theories whose algebraic structure depends on the value of a parameter. The primary example is the ℏ → 0 limit of …
Is the classical limit “singular”?
We argue against claims that the classical ℏ → 0 limit is “singular” in a way that frustrates an eliminative reduction of classical to quantum physics. We show one precise sense in …
Probabilism for stochastic theories
I defend an analog of probabilism that characterizes rationally coherent estimates for chances. Specifically, I demonstrate the following accuracy-dominance result for stochastic …
