When you're a child - and my understanding of it is very basic - but when you're a very young child, the stimuli around you prompt your brain to form synapses. Once they're there, they're there, but if they don't form by a certain age, they're not going to.

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 tend toward the pessimistic end of the spectrum, and unfortunately there's little in human history to convince me that pessimism is unwarranted.

I am not your God. Or if I am, I'm no God you can seek out for deliverance or explanation. I'm the kind of God who would eat you without compunction if I were hungry.

You wish they understood, as you do, that there is no escape and never was, that from the moment two cells combined to become one they were doomed. You wish they understood that there is joy in this fact, greater joy and love in just this one last moment than they experienced in the entirety of their lives. Because even in this last moment there is still Everything, whole galaxies and eons, the sum total of every experience across time, shrunk to the head of a pin, theirs for the asking, right here, right now. And so anything, anything, anything is possible.

On a micro level, if we're not terribly lucky, this sort of thing can happen to us quite frequently - the political becoming the personal in dramatic and irreparable ways. I remember the first time I went out into the desert, passing by all these mine fields and getting the history on them from my guide and realizing all these murderous mechanisms were real, were just sitting out there waiting for a victim, and some of them had been for sixty, seventy, eighty years.

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.
