Praise for Princeton's previous editions: "Enthralling... After reading it, we cannot see the past in the same comforting haze of age-old stories, faithfully and uncritically retold from teacher to pupil down the years... Invaluable for mathematics teachers at all levels."--New Scientist Praise for Princeton's previous editions: "What is valuable here is the unified approach that Joseph brings ... and the non-technical clarity that the attempt to reorder historical priorities and educate his readers out of their European prejudices requires."--Times Literary Supplement
