`What this book is full of, on almost every page, are quotations. They are well chosen, trenchant, and presented in their original language and an English translation. The effect is to eavesdrop on a long, continuing conversation, the conversation that is the life of mathematics as discussed by leading mathematicians. Here they are caught saying interesting, insightful, provocative things. They are by no means confined to definitions and statements of theorems, they are allowed to tell you why they think something is important, charming, useful, how it was found, who is responsible.'
