"Decline of the West" is a comprehensive historical and philosophical work that explores the rise and fall of civilizations. The author argues that every civilization has a life cycle, from birth to maturity and finally to decline. He suggests Western civilization is in its final stage of decline, comparing it to the end phases of the Greco-Roman civilization. The book also introduces the concept of 'pseudomorphosis', where a civilization is so deeply influenced by a previous culture that it suppresses its own authentic culture.

This book is a critique of the Treaty of Versailles, written by a British economist who was part of the British delegation to the peace conference. The author argues that the harsh reparations and economic measures imposed on Germany after World War I were unfair and would lead to economic instability and another war. He suggests that a more just and economically sound approach would have been to rebuild Germany and integrate it into the global economy, rather than punishing it.
