"The treatment of basic issues in epistemology is quite nicely done, and although the book is intended as an introduction, it is not confined to the coverage of elementary topics. Musgrave does devote a good deal of space to the discussion of such standard epistemological material as skepticism, but he also includes interesting, elegant, and informative summaries of problems and theories in logic, semantics, and the philosophy of mathematics. The book can be read profitably by anyone with an interest in epistemology and its history." Douglas M. Jesseph, Isis
