Here is a unique work of reference. Not only does it unite studies which explore the syntax and semantics of tense or modality, but it is the first book of its kind to embrace the interaction of tense and modality within a coherent generative model.

The relationship between formal logic and general philosophy is discussed under headings such as A Re-examination of Our Tense-Logical Postulates, Modal Logic in the Style of Frege, and Intentional Logic and Indeterminism.

The only book to investigate the parallel between what happens at other times and what happens in other possible worlds.

This book offers a new approach to the representation of meaning of temporally-located utterances and discourses. Temporality, the author suggests, should be taken to mean degrees of certainty, understood in turn as degrees of acceptability concerning the eventuality referred to in the speaker's utterance.

Timothy Williamson gives an original and provocative treatment of deep metaphysical questions about existence, contingency, and change, using the latest resources of quantified modal logic. Contrary to the widespread assumption that logic and metaphysics are disjoint, he argues that modal logic provides a structural core for metaphysics.

This comprehensive review and critical synthesis of research on modality focuses on formal theories within linguistics and related aspects of philosophical logic. It will be welcomed by students of linguistics at graduate level and above, as well as by researchers in philosophy, computational science, and related fields.

In this book, Kit Fine draws together a series of essays, three of them previously unpublished, on possibility, necessity, and tense.
