The thing that defines a species is that all members have the same addressing system for their DNA.

Each step is not too improbable for us to countenance, but when you add them up cumulatively over millions of years, you get these monsters of improbability, like the human brain and the rain forest. It should warn us against ever again assuming that because something is complicated, God must have done it.

My mind is open to the most wonderful range of future possibilities, which I cannot even dream about.

Religion ends and philosophy begins, just as alchemy ends and chemistry begins, and astrology ends and astronomy begins.

From my perspective, God cannot be completely contained within nature, and therefore God's existence is outside of science's ability to really weigh in.

It is absolutely safe to say that if you meet somebody who claims not to believe in evolution, that person is ignorant, stupid or insane (or wicked, but I'd rather not consider that).

People sometimes say that you must believe in feelings deep inside, otherwise you'd never be confident of things like 'My wife loves me'. But this is a bad argument. There can be plenty of evidence that somebody loves you. All through the day when you are with somebody who loves you, you see and hear lots of little tidbits of evidence, and they all add up. It isn't purely inside feeling, like the feeling that priests call revelation. There are outside things to back up the inside feeling: looks in the eye, tender notes in the voice, little favors and kindnesses; this is all real evidence.
