"Theory of everything" of Western civilization in the age of Capitalism and global shifts caused. Quigley can connect historical dots spanning centuries and presents his view with extreme lucidity, whether it's relation between Byzantine tradition of Russia and it's totalitarian tendencies in the 20th Century or between ancient German tribalism and modern Nazism, not to mention the more obvious ones such as impact of economy on politics, war or individual social classes. Before you try to reinvent the wheel by thinking about how modern society transforms traditional relations read this first. For all it's scope it's a page turner.
History of the past two centuries, has in the main been driven by the concealed ambitions of a controlling elite.
This book provides credible explanation of elite's perspective for control ,transforming the apparently random events of the past into a picture of directed and self serving, happenings. Providing a logical explanation of the motivations behind the actions that mold history.
Quigley's Tragedy and Hope is a very important historical work describing the intrigues of powerful financial and industrial interests aiming to dominate the world. His description of world-changing historical facts and events is without doubt one of his many strong points.
Among weak points are some important lacunae, e.g., the extensive chapter on international Socialism fails to investigate the links between the latter and the financial interests described earlier.
Another point is Quigley's personal interpretation of historical events, e.g., he attempts to explain social and political developments like the rise of German nationalism in terms of an alleged "German thirst for the coziness of a totalitarian way of life" that of course ignores the fact that nationalism - on the ascendance in most European countries at the time - was largely a reaction to internationalist movements like Socialism threatening the sovereignty and identity of all European nations.
I found that some of these points are helpfully addressed in The Milner-Fabian Conspiracy by Ioan Ratiu.
