Preface Most of the papers in this volume originate from the workshop Vagueness in Communication that was held during the 2009 European Summer School in Logic, Language and Information in Bordeaux, France. Although vagueness has long since been an important topic in philosophy, logic and linguistics, some recent advances have made the functions of vagueness in natural language communication an exciting and timely research area. This renewed interest has a distinct cross-disciplinary character and has spawned many new research questions. The workshop brought together researchers whose work contributes to the cross-disciplinary line of inquiry, in particular by broadening the empirical base for the study of vagueness, by offering a synthesis of theories from different disciplines, and by addressing the pragmatics of vagueness. It thereby provided a forum for lively discussions on recent and on-going work. The workshop was organized by the four editors of the present volume and Manfred Krifka, who unfortunately could not participate in the editorship of this volume because of other commitments. We would like to thank all the workshop participants for their contributions to the success of the workshop and the quality of the papers in this volume. Specifically, we thank the Program Committee, Graeme Forbes, Peter Gärdenfors, Hans Kamp, Stefan Kaufmann, Chris Kennedy, Ewan Klein, Manfred Krifka, Manfred Kupffer, Louise McNally, Christian Plunze, Marieke Schouwstra, Markus Schrenk, Yoad Winter and Thomas Ede Zimmermann for their help in selecting suitable contributions. We would also like to acknowledge the additional referees that were willing to advise us and the authors on the papers for this volume: Marta Abrusan, Anton Benz, Chris Kennedy, Sveta Krasikova, Chris Potts, Diania Raffman, David Schlangen, Kristen Syrett and Frank Veltman. We would like to thank Matthias Daubitz for TEXnical and editorial support during the preparation of the final version of this volume. Rick Nouwen acknowledges support from the Netherlands Organisation for Scientic Research (NWO) for the Degrees Under Discussion project. Robert van Rooij is supported by the NWO for the On Vagueness And How to Be Precise project as well as the ESF VAAG project. thanks the German Research Foundation DFG for its financial support through grants SA/925-1 and SA/925-4, the latter within the Eurocores LogiCCC program as part of the research project VAAG. The completion of this volume was furthermore aided by a grant from the ESF within the Eurocores LogiCCC program for editorial support. November 2010 Rick Nouwen
