All qualified physicists, biologists, cosmologists and geologists agree, on the basis of massive, mutually corroborating evidence, that the earth's age is at least four billion years.

There's a natural tendency for children to, in some sense, inherit the cultural values of their parents. I'm not against that, that's fine, that's wonderful. What I am against is labelling. Nobody ever labels a child a cricketer because his father is a cricketer, but they do label a child a Catholic because his parents are Catholic. I think it's more or less unique. Nobody ever labels a child a socialist or a conservative or a liberal because that's what their parents are.

We accept that people are irrational for good Darwinian reasons. But I don't think we should be so pessimistic as to think that therefore we're forever condemned to be irrational.

Barring a theoretical resolution, which I think is unlikely, you either have to say there are zillions of parallel universes out there that we can't observe at present or you have to say there was a plan. I actually find the argument of the existence of a God who did the planning more compelling than the bubbling of all these multiverses.

I do believe that nice religious people make the world safe for extremists by teaching us [...] that faith is a virtue, teaching us that there's something good about holding beliefs without any substantiating evidence. Once you buy into that, [...] then the door is opened to extremists who defend their extremism by saying, 'Oh well, it's my faith, you can't touch it, you can't criticise my faith, I don't even need to defend it because faith is faith.'

To me, the right approach is to say we are profoundly ignorant of these matters. We need to work on them. But to suddenly say the answer is God - it's that that seems to me to close off the discussion.

Indeed, organizing atheists has been compared to herding cats, because they tend to think independently and will not conform to authority. But a good first step would be to build up a critical mass of those willing to 'come out,' thereby encouraging others to do so. Even if they can't be herded, cats in sufficient numbers can make a lot of noise and they cannot be ignored.
