Book excerpt: A brilliant account of religion's role in the political thinking of the West, from the Enlightenment to the close of World War II.The wish to bring political life under God's authority is nothing new, and it's clear that today religious passions are again driving world politics, confounding expectations of a secular future. In this major book, Mark Lilla reveals the sources of this age-old quest-and its surprising role in shaping Western thought. Making us look deeper into our beliefs about religion, politics, and the fate of civilizations, Lilla reminds us of the modern West's unique trajectory and how to remain on it. Illuminating and challenging, The Stillborn God is a watershed in the history of ideas.
