Talk: Joshua Norton

The Geneva Symmetry Group, Beyond Spacetime, and the Space and Time After Quantum Gravity Project are happy to present

Joshua Norton (American University Beirut):
Incubating a future metaphysics: quantum gravity

Wednesday, 21 September, 18:00 (note the new starting time!)

Room L107 at 2, Rue De-Candolle

Anyone who wishes to attend this talk is welcome. The talk will be 2 Einsteins (out of 5).

Abstract: In this talk, I will argue that metaphysicians ought to utilize quantum theories of gravity (QG) as incubators for a future metaphysics. In §1, I will argue why this ought to be done. In §2, I will present case studies from the history of science where physical theories have challenged both the dogmatic and speculative metaphysician. In §3, I will present two theories of QG and demonstrate the challenge they pose to certain aspects of our current metaphysics; in particular, how they challenge our understanding of the abstract-concrete distinction. In this section I demonstrate how five different accounts of the distinction each fail to hold under the received interpretations of loop quantum gravity and string theory. The central goal of this talk is to encourage metaphysicians to look to physical theories, especially those involving cosmology such as string theory and loop quantum gravity, when doing metaphysics.
