This volume examines explicitly the question of how the semantics and pragmatics of a number of expressions might be responsibly discussed. In the past, the temptation has been for the expressions in question to be discussed either in terms of the semantics, or in terms of the pragmatics, but extremely rarely in terms of both. This book shows how revealing analyses for this interface can be provided for the expressions in question. In specially commissioned chapters from leading authors, the points of view represented include linguistics, logic, computational linguistics, and philosophy.
