This edited collection provides new perspectives on some metaphysical questions arising in quantum mechanics. These questions have been long-standing and are of continued interest to researchers and graduate students working in physics, philosophy of physics and metaphysics. It features contributions from a diverse set of researchers, ranging from senior scholars to junior academics, working in varied fields, from physics to philosophy of physics and metaphysics. The contributors reflect on issues about fundamentality (is quantum theory fundamental? If so, what is its fundamental ontology?), ontological dependence (how do ordinary objects exist even if they are not fundamental?), realism (what kind of realism is compatible with quantum theory?), indeterminacy (can the world itself exhibit ontological indeterminacy?). With contributions from both physicists (including Nobel Prize winner Gerard 't Hooft), science communicators and philosophers.

Autorentext

Valia Allori has studied physics and philosophy first in Italy, her home country, and then in the United States. She has worked in the foundations of quantum mechanics, with the aim of understanding how we can use our best physical theory to answer general metaphysical questions about the nature of reality. She has been a 2017-18 National Humanities Center Fellow and she is a Fellow of the John Bell Institute for the Foundation of Physics. She is currently Professor in the Philosophy Department of Northern Illinois University.
