Why do cultures commit suicide? Why are we witnessing a new great extinction of peoples? Why is the economic crisis really a spiritual crisis? Probing the inner workings of civilization in a tour d'horizon of cultural decline, Spengler argues that Europe's postnational, secular dystopia is a death trap, that the onslaught of modernity has plunged Islam into an even greater crisis, and that the destiny of nations is decided in the human heart, by religion. Christian America, in spite of its follies and gullibility, has the spiritual strength to restore the faith of the West. This book presents, in one comprehensive volume, the wide scope of Spengler's theories on Christianity, Islam, America, the financial crisis, horror movies, modern art, Israel, Tolkien's Middle Earth, tribalism, the global balance of power, demography, and sex in the twenty-first century. These highly original essays may provoke you, even frighten you--but never bore you.
