If you look up at the Milky Way through the eyes of Carl Sagan, you get a feeling in your chest of something greater than yourself. And it is. But it's not supernatural.

By all means let's be open-minded, but not so open-minded that our brains drop out. -this quote is actually found in Carl Sagan's book The Demon Haunted World: Science as a Candle in the Dark, where he attributes it to engineer James Oberg, who says he stole it from someone else.

It is possible in medicine, even when you intend to do good, to do harm instead. That is why science thrives on actively encouraging criticism rather than stifling it.

Indeed, organizing atheists has been compared to herding cats, because they tend to think independently and will not conform to authority.

Not only is science corrosive to religion, but religion is corrosive to science. It teaches people to be satisfied with trivial non-explanations and blinds them to the wonderful real explanations that we have within our grasp.

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.
