"Nola and Sankey's Theories of Scientific Method provides a comprehensive and thoroughly excellent introductory textbook to the philosophy of science. The discussion is fresh and lively; and the focus upon the distinction between methods and meta-methods not only helps to situate some otherwise rather abstract issues and debates, it also adds a valuable extra dimension to some familiar themes." - Notre Dame Philosophical Reviews "This book fills a distinct gap. No other book adopts its comprehensive approach. The expositions of the topics covered are clear and accessible and the emphasis on 'meta' methodological issues is distinctive and useful." - Barry Gower, University of Durham
