Most of the intelligence out there must be artificial intelligence. We keep looking for critters like us living on a planet like ours, where in fact the majority of the intelligence out there is not biological. That would be my argument.

In archaeology, context is the basis of many discoveries that are imputed to the deliberate workings of intelligence. If I find a rock chipped in such a way as to give it a sharp edge, and the discovery is made in a cave, I am seduced into ascribing this to tool use by distant, fetid and furry ancestors.

Our brains are continuing to evolve, and perhaps a few tens of thousands of years from now, our descendants will walk around with five pound brains, allowing them insights that we can't imagine.

While it may be disappointing, I have to confess to people who ask for my insights on the meaning of it all that astronomy doesn't provide any clearly useful data on matters of sin and souls.

I have faith in God, and I have faith in the fairness of the American people.

Disappointment is inevitable. But to become discouraged, there's a choice I make. God would never discourage me. He would always point me to himself to trust him. Therefore, my discouragement is from Satan. As you go through the emotions that we have, hostility is not from God, bitterness, unforgiveness, all of these are attacks from Satan.

Part of what my work has always been about is to show that the apocalyptic character of the gospel makes the everyday possible. It gives us the time that lets us care for one another as we are ill, helps us care for one another as we experience broken relationships, and helps us take the time to worship God in a world of such violence.

My mode as a writer is to layer different perspectives: the scientific, the philosophical, the political, the journalistic. When you layer them, you get a really wholesome, interesting picture.
