Book excerpt: The workings of Western intelligence in our day--whether in politics or the arts, in the humanities or the church--are as troubling as they are mysterious, leading to the questions: Where are we going? What in the world were we thinking? By exploring the history of four "cultures" so deeply embedded in Western history that we rarely see their instrumental role in politics, religion, education, and the arts, this timely book provides a broad framework for addressing these questions in a fresh way.
