Prof. Carroll Quigley's Tragedy and Hope: A History of the World in Our Time was one of the most important historical and predictive works to appear in the 20th century. The book was also among the century's most misunderstood and under-appreciated works of historiography.
First published in 1964, the scope of Tragedy is enormous, with 1,348 pages providing important insights into the forces that have shaped Western civilization. Quigley divided these forces into six aspects: military, political, economic, social, religious and intellectual. These six aspects then "fall into the three major areas of: the patterns of power, rewards and outlooks."
