The Year of Our Lord 1943: Christian Humanism in an Age of Crisis by Alan Jacobs. Very interesting book, with applications to the modern world and politics.
From the Amazon description:
By early 1943, it had become increasingly clear that the Allies would win the Second World War. Around the same time, it also became increasingly clear to many Christian intellectuals on both sides of the Atlantic that the soon-to-be-victorious nations were not culturally or morally prepared for their success. A war won by technological superiority merely laid the groundwork for a post-war society governed by technocrats. These Christian intellectuals-Jacques Maritain, T. S. Eliot, C. S. Lewis, W. H. Auden, and Simone Weil, among others-sought both to articulate a sober and reflective critique of their own culture and to outline a plan for the moral and spiritual regeneration of their countries in the post-war world.
