What does it mean to say that we live in a secular age? Almost everyone would agree that we--in the West, at least--largely do. And clearly the place of religion in our societies has changed profoundly in the last few centuries. In what will be a defining book for our time, Charles Taylor takes up the question of what these changes mean--of what, precisely, happens when a society in which it is virtually impossible not to believe in God becomes one in which faith, even for the staunchest believer, is only one human possibility among others.
