This book comprises all of John Bell's published and unpublished papers in the field of quantum mechanics, including two papers that appeared after the first edition was published. It also contains a preface written for the first edition, and an introduction by Alain Aspect that puts into context Bell's great contribution to the quantum philosophy debate. One of the leading expositors and interpreters of modern quantum theory, John Bell played a major role in the development of our current understanding of the profound nature of quantum concepts. First edition Hb (1987): 0-521-33495-0 First edition Pb (1988): 0-521-36869-3

### Reviews

"One of the leading expositors and interpreters of modern quantum theory, John Bell is particularly famous for his discovery of the crucial difference between the predictions of conventional quantum mechanics and the implications of local causality. This book includes all of John Bell's published and unpublished papers on the conceptual and philosophical problems of quantum mechanics." Astronomical Society of the Pacific

"...should be read by everyone interested in fundamental questions of nature." -American Journal of Physics
