What makes the words we speak mean what they do? Possible-worlds semantics articulates the view that the meanings of words contribute to determining, for each sentence, which possible worlds would make the sentence true, and which would make it false. M.J. Cresswell argues that the non-semantic facts on which such semantic facts supervene are facts about the causal interactions between the linguistic behaviour of speakers and the facts in the world that they are speaking about, and that the kind of causation involved is best analyzed using David Lewis's account of causation in terms of...

In ordinary discourse we appear to ta1k about many things that have seemed mysterious to philosophers. We say that there has been a hitch in our arrangements or that the solution to the problem required us to examine all the probable outcomes of our action. So it would seem that we speak as if in addition to eloeks, mountains, queens and grains of sand there are hitches, arrangements, solutions, probiems, and probable outcomes. It is not immediately obvious when we must take such ta1k as really assuming that there are such to develop tests for things, and one of the tasks in this book is...

Semantic Indexicality shows how a simple syntax can be combined with a propositional language at the level of logical analysis. It is the adoption of such a base language which has not been attempted before, and it is this which constitutes the originality of the book. Cresswell's simple and direct style makes this book accessible to a wider audience than the somewhat specialized subject matter might initially suggest.

Adverbial modification is probably one of the least understood areas of linguistics. The essays in this volume all address the problem of how to give an analysis of adverbial modifiers within truth-conditional semantics. Chapters I-VI provide analyses of particular modifiers within a possible worlds framework, and were written between 1974 and 1981. Original publication details of these chapters may be found on p. vi. Of these, all but Chapter I make essential use of the idea that the time reference involved in tensed sentences should be a time interval rather than a single instant. The final...

Is what could have happened but never did as real as what did happen? What did happen, but isn't happening now, happened at another time. Analogously, one can say that what could have happened happens in another possible world. Whatever their views about the reality of such things as possible worlds, philosophers need to take this analogy seriously. Adriane Rini and Max Cresswell exhibit, in an easy step-by-step manner, the logical structure of temporal and modal discourse, and show that every temporal construction has an exact parallel that requires a language that can refer to worlds, and...
