I just discovered that a new PDF version of Quigley's classic "Tragedy and Hope", is available for free download HERE Follow the link and be sure to download a copy to your computer in case it disappears again.
Here is an excerpt from the introduction by Michael L Chadwick.
"Tragedy and Hope: A History of the World in Our Time was published in 1966 and is
clearly one of the most important books ever written. Professor Quigley was an
extraordinarily gifted historian and geo-political analyst. The insights and information
contained in his massive study open the door to a true understanding of world history in
the nineteenth and twentieth centuries. In fact, if the scholar, student, businessman,
businesswoman, government official and general reader has not thoroughly studied
Tragedy and Hope there is no way they can understand the nineteenth and twentieth
centuries. It is a work of exceptional scholarship and is truly a classic. The author shouldhave received a Nobel Prize for his work".
