TRENDS IN LINGUISTICS is a series of books that open new perspectives in our understanding of language. The series publishes state-of-the-art work on core areas of linguistics across theoretical frameworks as well as studies that provide new insights by building bridges to neighbouring fields such as neuroscience and cognitive science. TRENDS IN LINGUISTICS considers itself a forum for cutting-edge research based on solid empirical data on language in its various manifestations, including sign languages. It regards linguistic variation in its synchronic and diachronic dimensions as well as in its social contexts as important sources of insight for a better understanding of the design of linguistic systems and the ecology and evolution of language. TRENDS IN LINGUISTICS publishes monographs and outstanding dissertations as well as edited volumes, which provide the opportunity to address controversial topics from different empirical and theoretical viewpoints. High quality standards are ensured through anonymous reviewing.

In 1962 a mimeographed sheet of paper fell into my possession. It had been prepared by Ernest Adams of the Philosophy Department at Berkeley as a handout for a colloquim. Headed 'SOME FALLACIES OF FORMAL LOGIC' it simply listed eleven little pieces of reasoning, all in ordinary English, and all absurd. I still have the sheet, and quote a couple of the arguments here to give the idea. • If you throw switch S and switch T, the motor will start. There fore, either if you throw switch S the motor will start, or, if you throw switch T the motor will start . • It is not the case that if John passes history he will graduate. Therefore, John will pass history. The disconcerting thing about these inferences is, of course, that under the customary truth-functional interpretation of and, or, not, and if-then, they are supposed to be valid. What, if anything, is wrong? At first I was not disturbed by the examples. Having at that time consider able personal commitment to rationality in general and formal logic in par ticular, I felt it my duty and found myself easily able (or so I thought) to explain away most of them. But on reflection I had to admit that my expla nations had an ad hoc character, varying suspiciously from example to example.

Axiomatic functionalism is a highly distinctive and challenging approach in the European functionalist tradition, which has been developed over the last 50 years. It emphasises clarity and accuracy of theory and methods with philosophical awareness for the analysis of languages. Axiomatic Functionalism is even more relevant at a time when functionalism is widely adopted and speculative universalism is being refuted. This book gives a clear orientation in the Axiomatic Functionalist approach with a new introduction, recent previously unpublished work, the latest version of the theory, a reference bibliography, key previously published articles, and an assessment of the contribution of Axiomatic Functionalism. The book covers the key areas of theory, methods, grammar, phonology, and semantics. It provides clear perspectives on a wide range of fundamental and current issues in linguistics.

Elementary set theory accustoms the students to mathematical abstraction, includes the standard constructions of relations, functions, and orderings, and leads to a discussion of the various orders of infinity. The material on logic covers not only the standard statement logic and first-order predicate logic but includes an introduction to formal systems, axiomatization, and model theory. The section on algebra is presented with an emphasis on lattices as well as Boolean and Heyting algebras. Background for recent research in natural language semantics includes sections on lambda-abstraction and generalized quantifiers. Chapters on automata theory and formal languages contain a discussion of languages between context-free and context-sensitive and form the background for much current work in syntactic theory and computational linguistics. The many exercises not only reinforce basic skills but offer an entry to linguistic applications of mathematical concepts. For upper-level undergraduate students and graduate students in theoretical linguistics, computer-science students with interests in computational linguistics, logic programming and artificial intelligence, mathematicians and logicians with interests in linguistics and the semantics of natural language.

How might evidence of language use – writing and speech – be used as a way of studying language? Corpus linguistics is the study of linguistic data from a particular language or set of languages. It is a fast-moving approach to studying language, and there is still a degree of divergence in how research questions are approached using corpus data. This book uses a framework, based on the work of Karl Popper, to explore a number of fundamental issues in corpus linguistics. It critically evaluates how these issues are tackled, and proposes a set of best practices for future research. It spells out why using corpus data is valuable, what we can learn from using it, and how we may most effectively progress our understanding of language by using such data. It is essential reading for researchers and students of language in general, and of applied linguistics and English language in particular.
