Current textbooks in formal semantics are all versions of, or introductions to, the same paradigm in semantic theory: Montague Grammar. Knowledge of Meaning is based on different assumptions and a different history. It provides the only introduction to truth - theoretic semantics for natural languages, fully integrating semantic theory into the modern Chomskyan program in linguistic theory and connecting linguistic semantics to research elsewhere in cognitive psychology and philosophy. As such, it better fits into a modern graduate or undergraduate program in linguistics, cognitive science, or philosophy. Furthermore, since the technical tools it employs are much simpler to teach and to master, Knowledge of Meaning can be taught by someone who is not primarily a semanticist.
Tense is one of the central issues of linguistics, and has been the focus of much attention in recent years. In this book, Declerck offers a detailed discussion of the temporal structures that are expressed by the combination of tense forms with the conjunction when. He is able to develop and test his earlier model and in doing so reveals the close relation between the semantics of when and the English tense system. Included are a detailed functional typology of English when-clauses, a model of the English tense system, an analysis of the possible tense combination - both normal and special - in head clauses and when-clauses, a discussion of the many different temporal interpretations of when-clauses, and a treatment of the special class of "narrative when-clauses". The specific focus is on how situations are located in time sentences involving both a head clause and a when-clause.
According to Peter Ludlow, there is a very close relation between the structure of natural language and that of reality, and one can gain insights into long-standing metaphysical questions by studying the semantics of natural language. In this book Ludlow uses the metaphysics of time as a case study and focuses on the dispute between A-theorists and B-theorists about the nature of time. According to B-theorists, there is no genuine change, but a permanent sequence of events ordered by an earlier-than/later-than relation. According to the version of the A-theory adopted by Ludlow (a position sometimes called "presentism"), there are no past or future events or times; what makes something past or future is how the world stands right now.
