The paper investigates the type of realism that best suits the framework of decoherence taken at face value without postulating a plurality of worlds, or additional hidden variables, or non-unitary dynamical mechanisms. It is argued that this reading of decoherence leads to an extremely radical type of perspectival realism, especially when cosmological decoherence is considered.

The paper discusses the physical role that the Bianchi identities play in general relativity and investigates whether these identities—qua part of a physical law—highlight some kind of a posteriori necessity in a Kripkean sense.

The paper considers a Humean reading of the laws of physics applied to the particular case of Bohmian mechanics. It is argued that this “Bohumian” strategy saves the letter but not the spirit of the Humean doctrine of supervenience. The conclusion is that the best defense for Bohumians is to question the fundamental existence of complex physical systems and their states by treating any reference to them as a convenient description of the underlying collection of Bohmian particles.

Furthermore, here are the two papers that paved the way to the present project:

The paper investigates whether the structure of Bohmian mechanics is compatible with the best-matching procedure, which lies at the heart of shape dynamics.

A follow-up paper in which the structure of a non-relativistic Bohmian theory based on best-matching is sketched, and its metaphysical consequences are discussed.
