But over time, Elshtain rediscovered Augustine--as well as Dietrich Bonhoeffer and John Paul II. "Who Are We? Reflections on Culture at the Millenium" is her meditation, drawing on the writings of Bohoeffer and the pope, on the problems of modern capitalist society. Elshtain's primary concern is the fragility of culture in a society in which "nothing is holy, sacred or off-limits," because "everything is for sale." Her vivid description is often more memorable than her solutions for the social problems she outlines, but "Who Are We?" offers more than enough to contemplate as it is--and clearly demonstrates that social criticism can be founded in faith as easily as in reason. Maybe Augustine should get his own class next time.
