Is "pluralism" a given, to be "dealt with" or "managed" -- or, is it a good thing in itself? The answer depends, I suppose, on what we mean by "pluralism." With the question in mind, here's an interesting essay by Peter Berger, in First Things, called "The Good of Religious Pluralism." (The essay summarizes Berger's recent book, The Many Altars of Modernity.) Here's a bit:
Secularization theory was not completely false; it was a massive exaggeration of what was a correct insight. It is beyond dispute that secular discourse, probably originating in modern science and technology, has transformed human life. (One such transformation: In premodern societies, almost half of all children died before age five; today most children, even in poor countries, live to adulthood.) The distinguished Canadian philosopher Charles Taylor wrote a big book with the title A Secular Age (2007). He gives a rich description of what he calls the "secular frame," a view of the world without religious transcendence. But he exaggerates the degree to which this discourse has pushed religion to the margins. We don't live in a secular age; we live in a pluralist age.
This pluralist age has important implications for religion, but they are different from those of secularity. We can speak of two pluralisms. The first concerns the fact that many religions and worldviews coexist in the same society. This is not unique to the modern era. The second kind of pluralism involves the coexistence of the secular discourse with all of these religious discourses. This pluralism, which is uniquely modern, has tended to accentuate the first kind, the pluralism of religions and worldviews. When I'm sick and my doctor is Jewish or Hindu, our shared secular vocabulary gives us a commonality that makes our religious differences something almost scandalous. How is it that we can agree on medical and other scientific or technical questions, yet not on ultimate matters?
There are some people who avoid the scandal of pluralism because they operate exclusively within a secular or a religious discourse (say, atheist Swedish sociologists, or Russian monks who practice the perpetual Jesus Prayer). However, most people of faith today manage to operate within both discourses. The question is not whether this can be done; we know that millions of people do it. The interesting question is how they do it.
