I just read an announcement for a new book: What Counts as Evidence in Linguistics, Edited by Martina Penke and Anette Rosenbach, and published this year by John Benjamins. According to the description of the book on the LingusitList, this book focuses on the innateness debate and shows how formal and functional approaches to linguistics have different perspectives on linguistic evidence. The three guiding questions for this volume are: What type of evidence can be used for innateness claims (or UG)?; What is the content of such innate features (or UG)?; and, How can UG be used as a theory guiding empirical research?
This book will be on my list of books to read after I finish my MA Thesis.
