It is all too easy to mistake passion that can change its mind for fundamentalism, which never will.

It's very important to try to inculcate into children moral rules, such as "do as you would be done by."

Suffering is a byproduct of evolution by natural selection, an inevitable consequence that may worry us in our more sympathetic moments but cannot be expected to worry a tiger - even if a tiger can be said to worry about anything at all - and certainly cannot be expected to worry its genes.

We have seen that living things are too improbable and too beautifully 'designed' to have come into existence by chance.

You can't blame science for being used for evil purposes. What you can do is say, 'This is an exceedingly powerful tool.' And you want to make sure it is used for good purposes, not bad ones. That is a political decision.

The list of things about which we strictly have to be agnostic doesn't stop at tooth fairies and celestial teapots. It is infinite. If you want to believe in a particular one of them - teapots, unicorns, or tooth fairies, Thor or Yahweh - the onus is on you to say why you believe in it. The onus is not on the rest of us to say why we do not. We who are atheists are also a-fairyists, a-teapotists, and a-unicornists, but we don't have to bother saying so.

The other way is the multiverse way. That says that maybe the universe we are in is one of a very large number of universes. The vast majority will not contain life because they have the wrong gravitational constant or the wrong this constant or that constant. But as the number of universes climbs, the odds mount that a tiny minority of universes will have the right fine-tuning.
