There's this thing called being so open-minded your brains drop out.

I've always been antagonistic to any naïve application of the selfish gene theory to politics. Some people have attempted to suggest that it means we are selfish or we should be selfish.

The feeling of awed wonder that science can give us is one of the highest experiences of which the human psyche is capable. It is a deep aesthetic passion to rank with the finest that music and poetry can deliver. It is truly one of the things that make life worth living and it does so, if anything, more effectively if it convinces us that the time we have for living is quite finite.

I am not absolutely positive there is no god. Only in the sense that I'm not absolutely positive there is no large china teapot in orbit in the solar system.

Science has taught us, against all intuition, that apparently solid things like crystals and rocks are really almost entirely composed of empty space. And the familiar illustration is the nucleus of an atom is a fly in the middle of a sports stadium, and the next atom is in the next sports stadium.

It's a horrible idea that God, this paragon of wisdom and knowledge, power, couldn't think of a better way to forgive us our sins than to come down to Earth in his alter ego as his son and have himself hideously tortured and executed so that he could forgive himself.

Our leaders have described the recent atrocity with the customary cliche: mindless cowardice. Mindless may be a suitable word for the vandalising of a telephone box. It is not helpful for understanding what hit New York on September 11. Those people were not mindless and they were certainly not cowards. On the contrary, they had sufficiently effective minds braced with an insane courage, and it would pay us mightily to understand where that courage came from. It came from religion.
