I think we certainly benefit from social institutions which encourage us towards moral behavior. It's very important to have law. It's very important to have a moral education.

Science replaces private prejudice with public, verifiable evidence.

Everybody is an atheist in saying that there is a god - from Ra to Shiva - in which he does not believe. All that the serious and objective atheist does is to take the next step and to say that there is just one more god to disbelieve in.

Hence, at the moment of the creation of the universe, God could also have activated evolution, with full knowledge of how it would turn out, perhaps even including our having this conversation. The idea that he could both foresee the future and also give us spirit and free will to carry out our own desires becomes entirely acceptable.

Science has eradicated smallpox, can immunise against most previously deadly viruses, can kill most previously deadly bacteria. Theology has done nothing but talk of pestilence as the wages of sin.

Charles Darwin made arguably the greatest discovery any human has ever made. He was a man of great persistence. He wasn't probably a natural genius, he worked very hard - even though he was an invalid. He was a great family man, a very nice man. I think he was admirable in all sorts of ways.

Such is the breathtaking speciesism of our Christian-inspired attitudes, the abortion of a single human zygote can arouse more moral solicitude and righteous indignation than the vivasection of any number of intelligent adult chimpanzees! The only reason we can be comfortable with such a double standard is that the intermediates between humans and chimps are all dead.
