Several of the essays in this volume were first presented at the conference “Wittgenstein, Philosophy of Mind, and Naturalism” held at the University of Bergen on June 12–13, 2015. The editors were co-organizers of this conference, and they would like to thank the Universitetsfond at the University of Bergen as well as the “Representationalism or Anti-Representationalism?” project at the Norwegian University of Science and Technology for the generous support that made this event possible. In addition, we would like to express our gratitude to Andrew Weckenmann and to co-editor Alexandra Simmons from Routledge for their help and patience throughout the process of putting this volume together. Thanks are also due to series co-editor Eugen Fischer for much guidance along the way. Finally, we would like to thank our contributors, whose hard work and philosophical acumen made this volume possible.
