Spengler's new book "How Civilizations Die"

Reviewed at Forbes.

For Goldman demography is almost destiny.  He argues that demographics shed light on the rise and fall of nations, tribes, and civilizations... This leads him to one of his “universal laws,” namely, that “The history of the world is the history of humankind’s search for immortality.”  A large part of the book is about the intricate ways in which this law interacts with demographic changes, and sheds light on national/tribal destinies from antiquity to our days.
