And when you try to live there, to live in a place where you're betraying yourself over and over, not only do you grow to resent the hell out of it, and resent the hell out of whomever you're betraying and censoring yourself for, but the very idea of your self begins slowly and inexorably to erode. Until you realize one day out of the clear blue that you have no idea who your self is, anymore.

I know well what faith really means to people in their daily lives, as there are many people in my family whose lives are permeated by their faith: it dictates the way they behave and sustains them in tough times, of which we've had too many lately.

One of the great things about the Bible, one of the things I think keeps people coming back to it, is that it's nothing if not perpetually topical. You don't have to dig too deeply into today's paper to find slaves and masters, evil authorities.

I think of this a lot in the terms of books. Of course there's a big to-do culturally about e-books versus print books, sales models. The paradigm has changed but my perspective on it is that there's not going to be another paradigm to alight on because everything will continue to evolve so quickly that our brains won't be able to keep up with it.

Oscar Pistorius is now infamous for reasons that I think everybody knows about, but when I hit on his story and put it in the book, what I found fascinating was a description, from one of the scientists who helped Pistorius, of what the Paralympics will become. Because they don't place any restriction on enhancements for athletes, in the very near future the Paralympics will bear a closer resemblance to NASCAR than to the traditional Olympics. There will be a human-machine melding that will result in crazy feats of athleticism.

People have invoked the ghost of Hemingway quite a few times in writing about the book. I could get into sticky territory here if I let myself go on about this subject. The more I hear it, the more it rankles, frankly.
