"...an essential book for linguistics students and researchers interested in the latest trends." The Linguist List “This book presents a highly innovative approach to the semantics of natural language. The authors manage with admirable ease to draw together insights from different fields and show how their theory can actually explain facts rather than simply assuming them. This is not a trivial achievement: to derive even the most simple sounding conclusion requires a lot of effort. This book is a truly intellectual book, written with love for the subject. I consider it a must for everyone who is interested in events or natural language semantics in general.” The Bulletin of Symbolic Logic “This fine book is a welcome addition to the Explorations in Semantics series. The coverage of the very complex literature in the area is very good. Content, style, and presentation are all excellent, and tutorial exercises of the kind appropriate for use as a basis for a graduate seminar are included.” Mark Steedman, University of Edinburgh “This elegant book redefines the traditional study of temporal reasoning. Merging insights from cognitive science, computer science, and linguistics, the authors propose an event calculus for natural language that is computationally tractable and logically appealing. This original synthesis of AI and linguistic semantics feels like a natural fit from the start.” Johan van Benthem, University of Amsterdam and StanfordUniversity “This volume helps to bring the study of tense and aspect, and the correlative study of events in linguistic semantics, within the purview of algorithmic conceptions of meaning, and other notions derived from abstract computer science. It will be an important companion to classical logical and syntactic studies, contributing to what we may hope will be an eventual unification of the computational and classical viewpoints.” James Higginbotham, University of Southern California "Michiel van Lambalgen and Fritz Hamm have written a magnificent book on semantics of temporal discourse in natural languages... Their book introduces and applies an important new tool of philosophical analysis, and thus should be available in any good, analytically oriented philosophical library." Erkenntnis
