Phonological Knowledge addresses central questions in the foundations of phonology and locates them within their larger linguistic and philosophical context. Phonology is a discipline grounded in observable facts, but like any discipline it rests on conceptual assumptions. This bookinvestigates the nature, status, and acquisition of phonological knowledge: it enquires into the conceptual and empirical foundations of phonology, and considers the relation of phonology to the theory of language and other capacities of mind. The authors address a wide range of interrelated questions, the most central of which is this: is phonological knowledge different from linguistic knowledge in general? They offer responses to this question from a variety of perspectives, each of which has consequences for how phonology andlanguage are conceived. Each also involves a host of further questions concerning the modularity of mind and of language; whether phonology should be included in the language faculty; the nature-convention debate; the content of phonological elements and its relation to phonetic substance; theimplications of sign languages for phonology; whether functional and variationist considerations are relevant in phonology; how phonological knowledge arises; and, not least, the data and methods appropriate for phonological inquiry. Phonological Knowledge is an important contribution to the most fundamental issues in phonology and the understanding of language. It will interest researchers in and advanced students of phonology, linguistic theory, and philosophy of language. In addition to the editors, the authors are Mary Beckman, Silvain Bromberger, Jennifer Fitzpatrick, Paul Foulkes, Mark Hale, Morris Halle, John Harris, Harry van der Hulst, Robert Ladd, G. Lindsey, Scott Myers, Janet Pierrehumbert, Charles Reiss, Shelley Velleman, Marilyn Vihman, and LindaWheeldon. By relating foundational questions of phonology to their larger linguistic, cognitive, and philosophical contexts this book will generate interest not only among phonologists and their advanced students, but also among all those concerned to understand the forms and functions of language.
