The urge to move is natural and understandable. As will be the case throughout your life, no matter how long or brief, the choice is, in the end, yours. Simply bear in mind that most every choice will have consequences, and in this instance those consequences would likely be quite grave.

I haven't written a whole lot of nonfiction, but what I have written leads me to believe that it's an entirely different muscle. The ongoing paradox is that sometimes it's harder to get to the emotional truth of something when you only have the facts at your disposal.

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'm definitely excited by big ideas, both in what I write and what I read. Most days, reality is so mind-numbingly dull that I don't understand why someone would write strictly realistic stories, given the almost limitless freedom fiction provides. I don't see the point of making believe if you're not going to actually make believe: hang your ass out in the wind, push at every boundary, make almost unreasonable demands on your reader's willingness to suspend disbelief. This is dangerous, and prone to failure, but that's part of what makes it fun.

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.

Singularity theory is something that I do believe will come to pass, sooner or later, although whether or not in our lifetime I don't know, and I'm not sitting around waiting for my father to be resurrected. Readers probably have the impression from the book that I'm a lot more a of a techno kook than I actually am. It became a convenient fulcrum in the story, sort of a kaleidoscope through which to address religious and spiritual questions.

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.
