The Measure of Reality: Quantification in Western Europe, 1250–1600

Western Europeans were among the first, if not the first, to invent mechanical clocks, geometrically precise maps, double-entry bookkeeping, precise algebraic and musical notations, and perspective painting. More people in Western Europe thought quantitatively in the sixteenth century than in any other part of the world, enabling them to become the world's leaders. With amusing detail and historical anecdote, Alfred Crosby discusses the shift from qualitative to quantitative perception that occurred during the late Middle Ages and Renaissance. Alfred W. Crosby is the author of five books, including the award-winning Ecological Imperialism: The Biological Expansion of Europe, 900-1900 (Cambridge, 1986)

Alfred W. Crosby is Professor of American Studies, History, and Geography at the University of Texas, Austin, and he has been a Visiting Professor at Yale and the University of Hawaii
