I have always had great regard for this book as the one which relates the development of modern mathematical ideas in a readable fashion. --Michael F. O'Reilly, University of Minnesota in Morris<br> Outstanding scholarship and readability. One of only a couple of books available in English for in-depth historical studies at the fourth year/graduate level. --Charles V. Jones, Ball State University<br> The consistently high quality of presentation, the accuracy, the readable style, and the stress on the conceptual development of mathematics make [these volumes] a most desirable reference. --Choice<br> Without a doubt a book which should be in the library of every institution where mathematics is either taught or played. --The Economist<br> What must be the definitive history of mathematical thought....Probably the most comprehensive account of mathematical history we have yet had. --Saturday Review<br>
