We have the power to defy the selfish genes of our birth and, if necessary, the selfish memes of our indoctrination. We can even discuss ways of deliberately cultivating and nurturing pure, disinterested altruism - something that has no place in nature, something that has never existed before in the whole history of the world. We are built as gene machines and cultured as meme machines, but we have the power to turn against our creators. We, alone on earth, can rebel against the tyranny of the selfish replicators.

Science is the disinterested search for the objective truth about the material world.

THE MAJORITY of children born into the world tend to inherit the beliefs of their parents, and that to me is one of the most regrettable facts of them all

The gravitational constant, if it were off by one part in a hundred million million, then the expansion of the universe after the Big Bang would not have occurred in the fashion that was necessary for life to occur. When you look at that evidence, it is very difficult to adopt the view that this was just chance.

It would be intolerant if I advocated the banning of religion, but of course I never have.

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.'

My last vestige of 'hands off religion' respect disappeared in the smoke and choking dust of September 11, 2001, followed by the 'National Day of Prayer,' when prelates and pastors did their tremulous Martin Luther King impersonations and urged people of mutually incompatible faiths to hold hands, united in homage to the very force that caused the problem in the first place.
