The Demon in Democracy: Totalitarian Temptations in Free Societies, Ryszard Legutko, Encounter Books.

The book is written from a perspective of someone who after having lived for many years under communism and then for more than two decades under a liberal democracy has discovered that those two political systems have a lot in common, stem from the same historical roots in early modernity, and accept similar presuppositions about history, society, religion, politics, culture and human nature.
