In this new edition, Arthur Fine looks at Einstein\'s philosophy of science and develops his own views on realism. A new Afterword discusses the reaction to Fine\'s own theory. \"What really led Einstein . . . to renounce the new quantum order? For those interested in this question, this book is compulsory reading.\"&;Harvey R. Brown, American Journal of Physics \"Fine has successfully combined a historical account of Einstein\'s philosophical views on quantum mechanics and a discussion of some of the philosophical problems associated with the interpretation of quantum theory with a discussion of some of the contemporary questions concerning realism and antirealism. . . . Clear, thoughtful, [and] well-written.\"&;Allan Franklin, Annals of Science \"Attempts, from Einstein\'s published works and unpublished correspondence, to piece together a coherent picture of \'Einstein realism.\' Especially illuminating are the letters between Einstein and fellow realist Schrödinger, as the latter was composing his famous \'Schrödinger-Cat\' paper.\"&;Nick Herbert, New Scientist \"Beautifully clear. . . . Fine\'s analysis is penetrating, his own results original and important. . . . The book is a splendid combination of new ways to think about quantum mechanics, about realism, and about Einstein\'s views of both.\"&;Nancy Cartwright, Isis
