The Evolution of Civilizations

Carroll Quigley was a legendary teacher at the Georgetown School of Foreign Service. His course on the history of civilization was extraordinary in its scope and in its impact on his students.

Quigley defines a civilization as "a producing society with an instrument of expansion."
