Abstract

In this talk I attempt to explore two important aspects of modern philosophy of science. On the one hand, I discuss the general idea of a scientifically informed metaphysics; an up-to-date way to talk about existence, existents and their properties with special reference to scientific theories. On the other hand, I examine a methodological issue, the idea of theorem-proving philosophy: how to argue philosophically by means of mathematical theorems. The discussion is based on my paper (with A. Arageorgis): “On Particle Phenomenology without Particle Ontology: How Much Local Is Almost Local?” Foundations of Physics 43 (8):969-977 (2013). In this paper, we argue that the measurements local particle detections are supposed to simulate probe radically holistic aspects of relativistic quantum fields. We prove that in an axiomatic (Haag-Araki) quantum field theory on Minkowski spacetime, formulated in a Hilbert space , there is no positive observable, with norm less than or equal to 1, satisfying the conditions: (1) the expectation value of in the vacuum state is zero, (2) there is at least one vector state in in which the expectation value of is different from zero, and (3) there exists at least one spacetime region such that the non-selective measurement of leaves the expectation values of all observables in the local algebra of that region unaltered regardless of the state the system is in. The result reveals a tension between intuitions regarding localization and intuitions regarding causality: to save “particle phenomena” in the absence of particle ontology, one has to feign “particle” detectors with “good” properties as to locality but “bad” behavior as to causality.
