This book has grown out of an introduction to logic for linguists in Swedish published by Studentlitteratur, Lund, 1971, a German translation of which appeared in 1973 (Niemeyer Verlag). All the chapters of the Swedish book have been revised and several additions (including the whole of chapter 8) have been made. The goal is still the same: to give linguists and others interested in language an orientation in logic which will enable them to understand how logical concepts are used (or could be used) in linguistic theory, in particular semantics.

We have benefited from suggestions and critical remarks made by several people. In addition to several generations of students at the Department of Linguistics in Göteborg, who have had to act as our guinea-pigs, we want to thank Claes Åberg, who has read the book in manuscript at various stages of its development, Michael Grabski, who translated the Swedish book into German and who suggested a number of changes, many of which have been incorporated into the present version, and John Lyons, an editor of this series. We are also grateful to Peter Hinst for a devastating review of the German version in Zeitschrift für Germanistische Linguistik, 3: 3 (1975), with which we partly agree.
