On Two Wings: Humble Faith and Common Sense at the American Founding by Michael Novak
In this book, Novak probes the innermost convictions of Washington, Jefferson, Madison and the others who helped the American eagle take wing. He shows how they were able to find common ground by appealing to the God of the Hebrews. He traces what happened to this Hebrew metaphysics as the world of the founders became the world of modernity.
