`For the immediate future, however, this book should be (possibly chained!) in every university and college library, and, yes, in the library of every school which is intent on improving its mathematics teaching.'The Americal Mathematical Monthly, December 1991 `This book should make interesting reading for philosophers of mathematics, if they want to observe how mathematical ideas really develop.'Advances in Mathematics, 86, 1991
