It's the hardening of these narratives that makes peace so difficult. If each side can see the narrative, the claims that the other has, then there is a much more likely possibility of making a resolution. But what I see is the opposite. There is a total disclaiming of the validity of the other side, and talk that I find really unsettling, the kind of chatter you get from ultra-right Israelis and Hamas is of annihilation. In that kind of dialogue, there's no way to move toward peace.

We hear a lot about theological justifications for the conflicts, but very little about the scientific evidence, which in no way supports them. The time period in which Moses was leading his people out of Egypt, into the Promised Land, the Promised Land was Egypt. We know that. Archaeological records are very clear. The Egyptians were avid bureaucrats even in those days and kept very scrupulous records. I think it's important for us to realize this conflict is built on a legend. It has no scientific support.

There are many countries where you can only believe more or you can believe less. But in the United States we have this incredible smorgasbord, and it really interests me why people are drawn to one faith rather than another, especially to a system of belief that to an outsider seems absurd or dangerous.

Scientology is probably the most stigmatized religion in America already.

I don't dispute Scientology can help people; I think that is a very important fact to keep in mind.

I grew up in the American South, the segregated South. Now we have a black man who is president. It was an age of apartheid, and now that's over. It was an age of two superpowers frozen in a cold war, and now that's resolved. So history marches on, except for this Arab-Israel conflict, which seems to have a claim on being eternal.

When I'm writing about complicated subjects, it usually involves a world. It could be the world of Scientology or the world of Al Qaeda, or the world of counter-terrorism.I look for emblematic beasts of burden - what I call "donkeys" - who can carry the reader through this world. They serve a different purpose. Donkeys are not especially interesting or likeable, but they are serviceable. They will take you into this world. The distinction I'm trying to make is: It's not about them. It's about the world.
