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 wanted to be a scientist. My undergraduate degree is in biology, and I really did think I might go off and be some kind of a lady Darwin someplace. It turned out that I'm really awful at science and that I have no gift for actually doing science myself. But I'm very interested in others who practice science and in the stories of science.

There was a time when 'science' meant the systematic pursuit of knowledge through experimentation and observation. But it's rapidly becoming a synonym for progressive politics and materialist philosophy.

Those Dutchmen had hardly any imagination or fantasy, but their good taste and their scientific knowledge of composition were enormous.

Secretly, I'm a real big nerd. I'd rather stay home and play Scrabble than go to a Hollywood party, any day of the week. And I love reading about history and watching the Discovery Channel.
