Yehoshua Bar-Hillel (1915-1975) was one of the leading intellectuals of Israel and of the world. His work ranged over mathematics, applied logic, communication theory, analytic philosophy, philosophy of science, and linguistics. Creative, patient, attentive, and critical, Bar-Hillel was a superb philosopher. In addition, how humane he was may be learned from the memorial tributes to him which initiate this volume. Bar-Hillel was born in Vienna, and came to Israel, then Palestine, in 1933. He took his M. A. (1938) and Ph. D. (1949) at the Hebrew University of Jerusalem, where his subsequent career continued, as Research Fellow (1949-53), Senior Lecturer in Philosophy (1953-58), Associate Professor of Philosophy (1958-61), and Professor of Logic and Philosophy of Sci ence (1961-75). He was often abroad as visiting professor (Berkeley, 1960- 61; Michigan, 1965; La Jolla, 1966-67; Konstanz, 1971; Berlin, 1972), or as a research scholar, notably at the M. lT. Research Laboratory for Elec tronics during the early 1950's. Bar-Hillel was the Secretary and guiding spirit of the Organizing Committee for the 3rd International Congress for Logic, Methodology and Philosophy of Science, held in Jerusalem in 1964. During 1966-68, he was President of the Division of Logic, Method ology and Philosophy of SCience of the International Union of History and Philosophy of Science, and in 1967 President of the International Union.

Noam Chomsky's work has had a decisive influence on the development of linguistics and more broadly on the study of mind and language. This book, which contains two new papers by Chomsky, assesses that 'Chomskyan Turn' in linguistics and the cognitive sciences. The articles by Chomsky, 'Linguistics and Adjacent Fields' and 'Linguistics and Cognitive Science', are particularly valuable both in reviewing the current state of the generative enterprise and in presenting his new 'functional' approach to principles of Universal Grammar. The chapters making up the second part of the volume explore different facets of Chomsky's contribution to linguistics and the adjacent fields of philosophy and psychology. Phonology is the topic of Bromberger and Halle's chapter; Hornstein's paper considers aspects of semantics and Kasher's, pragmatics. Other contributions centre on psychological issues raised by Chomsky's writing. Matthews discusses the psychological reality of grammars; Pylyshn, representational realism and Wexler, language maturation. The articles by Fromkin and by Newmeyer discuss the development of the generative tradition while Leiber considers aspects of 'Cartesian Linguistics'.
