Evolution of Civilizations

The Evolution of Civilizations is a comprehensive and perceptive look at the factors behind the rise and fall of civilizations. Quigley defines a civilization as "a producing society with an instrument of expansion." A civilization's decline is not inevitable but occurs when its instrument of expansion is transformed into an institution - that is, when social arrangements that meet real social needs are transformed into social institutions serving their own purposes regardless of real social needs.Quigley, Carroll is the author of 'Evolution of Civilizations' with ISBN 9780913966563 and ISBN 0913966568.
