Aim of the workshop
The aim of the workshop is to illuminate the philosophy of quantum physics from different perspectives. It is intended as a forum for new approaches to the epistemological and ontological challenges suggested by quantum physics.


The workshop was carried out in an informal way, with emphasis on discussions. The program was decided spontaneously on site. Unsolved questions inspired an open working environment.


The Templeton Research Fellows Program at IQOQI Vienna is a new and world-wide unique scheme to bring together philosophers and scientists in an attempt to generate new philosophical approaches and foundations for modern science. A particular focus of the program is to provide a basis for the challenging epistemology suggested by quantum physics. This program of direct extended collaboration among philosophers and physicists challenges participants to generate new perspectives and interpretations of the world consistent with experimental findings, theoretical advances, and human experience.


Senior Fellows: The workshop brought together philosophers and physicists. Several speakers are international leaders in the philosophy of science.
