Theoretical Philosophy Forum

Adrien Barton (Department of Philosophy, CEU, Budapest):

Rationality and observations in an Everettian universe

In order to solve quantum paradoxes, the contemporary Everett interpretation of quantum mechanics postulates a structure of the universe as a collection of splitting worlds. Still, it has sometimes been argued that this surprising description of reality should not lead to any difference in rationality or observational predictions, as compared with a unique, non-Everettian universe. In my talk, I will present a version of the contemporary Everett interpretation of quantum mechanics, in the continuation of Hilary Greaves’ approach. I will present and discuss thought experiments (quantum Sleeping Beauty, quantum suicide) which will show how rational decisions, epistemic evaluations and observational predictions can differ in Everettian and non-Everettian universes. This will bring up the question of scientific realism as a central issue.

The Forum is open to everyone, including students, visitors, and faculty members from all departments and institutes.
