Throughout the first half of this century, the history of phonology is the history of linguistics, inasmuch as it is in phonology where the foundations of linguistics are sought and where a degree of explicitness and rigor is reached that everyone has later taken for granted. exemplary Stephen Anderson, one of today's leading phonologists, provides in this book the chronicle of an exemplary scientific adventure and expounds with finesse and lucidity some basic questions that, raised by successive schools in different ways, are still relevant today. If anyone thinks of phonology as a set of recipes, he will be surprised at the depth of these questions, the intelligence that has gone into solving them, and the considerable implications they have for other aspects of human language and knowledge.
