NINTH PRINCIPIA INTERNATIONAL SYMPOSIUM Possible worlds and their applications in philosophy and the sciences The Ninth Principia International Symposium will be held in Florianopolis, Brazil, from August 17th to 20th, 2015, focusing on possible worlds and their applications in philosophy and the sciences. Possible worlds have been widely used in many areas of philosophy, in particular, in metaphysics, philosophy of language, philosophy of physics, and philosophical logic. We welcome contributions that address any aspect of the significance of possible worlds or that examine critically their use in philosophy or in the interpretation of the sciences. The eight previous symposia in this series have been devoted, respectively, to Principles in Philosophy and in the Sciences (1999), The Philosophy of Bertrand Russell (2001), The Philosophy of Willard van Orman Quine (2003), The Philosophy of Donald Davidson (2005), The Philosophy of Bas van Fraassen (2007), Charles Darwin and his impact on philosophy and science (2009), The Philosophy of Nelson Goodman (2011) and The Philosophy of Hilary Putnam (2013). This Symposium is being organized by the Epistemology and Logic Research Group (NEL-UFSC), in association with Principia, and supported by the Graduate Program in Philosophy and the Philosophy Department of Federal University of Santa Catarina (UFSC), Brazil.
