Hubbard set up the Church of Scientology in Hollywood in 1954 for a reason. He understood that celebrity was increasingly a feature of American public life, and celebrities themselves were going to be worshipped as minor deities were in the ancient world. The idea was: if you could get them, think how many people would follow.

Chronology can be dangerous. You can get so linear that it becomes robotic for the reader.

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.

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.

I don't want to constantly be writing about terrorism and strife.

People often pulled into Scientology want to address personal problems in their life, and Scientology says we have technology that addresses these kinds of problems. Just focusing on the problems and trying to remedy them can be helpful.

Churches are tax exempt because they are supposed to provide a public good. To prove that good to the IRS, churches arent supposed to hoard their money. They are supposed to spend it on goods and services for the faithful. Under this pretense, the church has made massive investments in tax free real estate all over the world. And when it comes to labor costs, they are almost free.
