582 Briefly Noted Flexibility Principles in Boolean Seman- tics: The Interpretation of Coordination, Plurality, and Scope in Natural Language Yoad Winter (Technion, Israel Institute of Technology) Cambridge, MA: The MIT Press (Current studies in linguistics, edited by Samuel Jay Keyser, volume 37), 2001, xi+297 pp; hardbound, ISBN 0-262-23218-9, $45.00 “Since the early work of Montague, Boolean semantics and its subfield of generalized quantifier theory have become the model- theoretic foundation for the study of mean- ing in natural languages. This book uses this framework to develop a new semantic theory of central linguistic phenomena in- volving coordination, plurality, and scope. The proposed theory makes use of the stan- dard Boolean interpretation of conjunction, a choice-function account of indefinites, and a novel semantics of plurals that is not based on the distributive/collective distinc- tion. The key to unifying these mechanisms is a version of Montagovian semantics that is augmented by flexibility principles: seman- tic operations that have no counterpart in phonology. “This is the first book to cover these ar- eas in a way that is both linguistically com- prehensive and formally explicit. On one hand, it addresses questions of primarily lin- guistic concern: the semantic functions of words like and and or in different languages, the interpretation of indefinites and their scope, and the semantic typology of noun phrases and predicates. On the other hand, it addresses formal questions that are mo- tivated by the treatment of these linguis- tic problems: the use of Boolean algebras in linguistics, the proper formalization of choice functions within generalized quanti- fier theory, and the extension of this the- ory to the domain of plurality. While pri- marily intended for readers with a back- ground in theoretical linguistics, the book will also be of interest to researchers and advanced students in logic, computational linguistics, philosophy of language, and ar- tificial intelligence.”—From the publisher’s an- nouncement Spatial Language: Cognitive and Com- putational Perspectives Kenny R.
