The Metaphysics of Physics - Natural Philosophy

My collaborators and I pursue a methodology of philosophy of nature that considers physics and metaphysics as constituting a seamless whole - in contrast to both a neo-positivist metaphysics that seeks to read metaphysical consequences directly off from the formalisms of physical theories and a neo-rationalist a priori metaphysics based on conceptual analysis. In this spirit, we seek to formulate a minimalist fundamental ontology of the natural world that combines atomism with relationalism about space-time and ontic structural realism: there are particles in the guise of matter points, but all there is to them are the distance relations among them, with these distance relations individuating the matter points. All change is change of these distance relations. We set out to show that this fundamental ontology covers the whole of physics, from Newtonian mechanics to quantum mechanics and quantum field theory, arguing for the Bohmian approach in the quantum domain, because it constitutes the best solution to the quantum measurement problem. What changes in the transition from classical to quantum physics is not the fundamental ontology, but the dynamical structure, that is, the parameters and equations employed to represent the change in the distance relations in a manner that is both as simple and as informative as possible.

This research is done in cooperation with Dirk-André Deckert (mathematical physics, LMU Munich), inserted into the Bohmian mechanics research network and supported by the Swiss National Science Foundation (SNSF) and the Cogito Foundation.
