It is possible to enjoy the Mozart concerto without being able to play the clarinet. In fact, you can learn to be an expert connoisseur of music without being able to play a note on any instrument. Of course, music would come to a halt if nobody ever learned to play it. But if everybody grew up thinking that music was synonymous with playing it, think how relatively impoverished many lives would be. Couldn't we learn to think of science in the same way?

You can't even begin to understand biology, you can't understand life, unless you understand what it's all there for, how it arose - and that means evolution.

If God wanted to create life and create humans, it would be slightly odd that he should choose the extraordinarily roundabout way of waiting for 10 billion years before life got started and then waiting for another 4 billion years until you got human beings capable of worshipping and sinning and all the other things religious people are interested in.

The mob hysteria over pedophiles has reached epidemic proportions and driven parents to panic. Today's Just Williams, today's Huck Finns, today's Swallows and Amazons are deprived of the freedom to roam that was one of the delights of childhood in earlier times (when the actual, as opposed to the perceived, risk of molestation was probably no less).

No matter how much knowledge and wisdom you acquire during your life, not one jot will be passed on to your children by genetic means. Each new generation starts from scratch.

Religion: Together we can find the cure.

The true scientific understanding of the nature of existence is so utterly fascinating; how could you not want people to share it? Carl Sagan, I think, said 'when you're in love, you want to tell the world.' And who, on understanding a scientific view of reality, would not, as it were, fall in love and want to tell the world.
