'In this thoroughly fascinating monograph, Alfred W. Crosby asks a fundamental question: How and why did it come to pass that Europeans, seemingly backward bumpkins in medieval times, became so successful as imperialists?' John Allen Paulos, LA Times 'The Measure of Reality has all the intellectual scope, vivid detail, imaginative interpretation and delicious wit that I expected from Crosby's ... Read moreearlier books. Here Crosby argues that Western Europeans were better imperialists than any humans before them in part because, from the thirteenth century onward, they thought about reality in quantitative terms and did so more consistently than other peoples. There is an important lesson here for today.' Joel E. Cohen, Rockerfeller University 'Crosby shows us how Europeans prepared for their world encompassing expansion after 1500 by learning how to measure, calculate and control the world around them by breaking reality into equal, arbitrary units. The Measure of Reality is a brilliant, provocative essay, as original and persuasive as his earlier Ecological Imperialism. A really significant little essay, full of new information and delightfully written as well.' William H. McNeill 'Western Europe did remake itself during that thousand years in a way that no other culture in the world did - or even attempted to do. And that is the transformation addressed in a very accessible and readable way by Crosby's stimulating, wide-ranging study of the intellectual development of the medieval West.'
