Authoritative, Compelling, provocative: internationally respected historian Felipe Fernandez-Armesto introduces you to the key historical and philosophical notions that have shaped our world since the dawn of civilization. Over 175 of the world's most pivotal ideas are crystallized and clearly explained -- from cannibalism to zen, from time to the unconscious, from logic to chaos theory. The author's wide-ranging and unashamedly personal analysis is accompanied by a stimulating mix of contemporary and historical images, bringing often hard-to-grasp concepts vividly to life. Chronologically Arranged, the format of this book nevertheless allows you to start at the beginning or dip in at any point. The connections between ground-breaking ideas are highlighted throughout, along with expert suggestions for thought-provoking further reading.
