`Excellent introduction. Ideal for a first course in the subject.' Dr W.H. Newton-Smith, University of Oxford `A careful, clear, yet sophisticated introduction. It will meet the needs of able students with a particular concern for the physical sciences.' Barry Gower, Durham University `Clear, useful, accessible' M. Smithhurst, University of Southampton `splendid book. ... One of the book's many attractions is its balanced view of the relationship between physics and philosophy. ... Sklar's book is certainly serious; it is also genuinely introductory. ... this book is an expository tour de force.' Peter Lipton `Highly readable, informative and ... valuable ... a useful addition to a very good series, the Dimensions of Philosophy Series ... The main value of this volume is that it will provide an excellent introductory and intermediate textbook, which covers all of the key issues with which students must become familiar. The level of discussion of physical theory is ... clear and accurate throughout so that it will provide a stimulus for those students of physics who would like to know much more about the conceptual foundations of major branches of physical theory ... a superb teaching aid. Sklar has the merit of writing clearly, vigorously and with some wit, and this makes the volume very readable.' MIND
