The study of questions and answers is challenging for various fields of theoretical linguistics, logic, analytical philosophy, and more recently computer science. Research into questions and answers addresses old and raises new and important questions about the semantics / pragmatics interface and about the dynamics of interpretation. This book brings together current work on the topic as it has been developed in Amsterdam, and congenial academic sites, over the past 15 years. Amsterdam is one of the breeding grounds for the formal study of logic and language, for dynamic semantics, and for the study of questions and answers. It covers the major issues of pragmatic/semantic investigation, including logical relations, context dependence, information structure, and more. It illustrates how semantic/pragmatic stance can be used for problems in other areas of linguistic theorising.

The integrated theory of dynamic interpretation set out here will be a surprise to advanced researchers in linguistics. It combines classical formal semantics and modern dynamic semantics without altering the fundamental paradigm. At the book’s core lies a pragmatically motivated notion of a dynamic conjunction of meanings, an idea that is worked out in full formal detail. This is applied to linguistic phenomena that involve anaphora, quantification and modality. The author demonstrates that in each area of application existing data can be neatly combined with new dynamic insights, but more importantly, there is a genuine further pay-off: the work generates treatments of phenomena that were not initially intended, with functional readings of pronouns and quantifiers, ‘Hob-Nob’ sentences, and insights into what we now call ‘Pierce’s Puzzle’. The outcome of a decade of work by the Amsterdam School of dynamic semantics, this volume condenses and reflects upon a vital body of research.

Presented in this book is a theory of concept formation and understanding that does not make use of a notion of an innate mental language as a means of concept representation. Instead, experimental concepts are treated semantically as stabilising structuring of growing sets of data, which are sets of experienced satisfaction situations for expressions, and theoretical concepts are based on coherent sets of general sentences held true. There are two kinds of structures to be established: general concepts by means of similarity sets under perspectives and historical concepts. This gives rise to a theory of understanding new situations and expressions by integrating new data into established sets of data salva stability, or by extending the conceptual structure in a metaphorical or metonymical way. The theory provides a way to understand what identity between propositional attitudes amounts to, especially how people can have more or less the same belief.

This book develops a view of logic as a theory of information-driven agency and intelligent interaction between many agents - with conversation, argumentation and games as guiding examples. It provides one uniform account of dynamic logics for acts of inference, observation, questions and communication, that can handle both update of knowledge and revision of beliefs. It then extends the dynamic style of analysis to include changing preferences and goals, temporal processes, group action and strategic interaction in games. Throughout, the book develops a mathematical theory unifying all these systems, and positioning them at the interface of logic, philosophy, computer science and game theory. A series of further chapters explores repercussions of the 'dynamic stance' for these areas, as well as cognitive science.

Dynamic Epistemic Logic is the logic of knowledge change. This book provides various logics to support such formal specifications, including proof systems. Concrete examples and epistemic puzzles enliven the exposition. The book also offers exercises with answers. It is suitable for graduate courses in logic. Many examples, exercises, and thorough completeness proofs and expressivity results are included. A companion web page offers slides for lecturers and exams for further practice.

The logical study of language is becoming more interdisciplinary, playing a role in fields such as computer science, artificial intelligence, cognitive science and game theory. This new edition, written by the leading experts in the field, presents an overview of the latest developments at the interface of logic and linguistics as well as a historical perspective. It is divided into three parts covering Frameworks, General Topics and Descriptive Themes. Completely revised and updated - includes over 25% new material Discusses the interface between logic and language Many of the authors are creators or active developers of the theories
