I was brought up in a family which valued natural history. Both my parents knew the names of all the British wildflowers, so as we went walking the country, I was constantly being exposed to a natural history sort of knowledge.

I need to learn not to bend over backwards to be nice to faith-heads. Give these people an inch and they take a league. I think, as I did when I wrote The God Delusion, that the Roman Catholic Church is a disgusting institution, the second most evil religion in the world.

When I sign books, I get lines of people and what they usually say is: "Thank you. You have changed my life." I am really moved by that.

There is an anaesthetic of familiarity, a sedative of ordinariness which dulls the senses and hides the wonder of existence. For those of us not gifted in poetry, it is at least worth while from time to time making an effort to shake off the anaesthetic. What is the best way of countering the sluggish habitutation brought about by our gradual crawl from babyhood? We can't actually fly to another planet. But we can recapture that sense of having just tumbled out to life on a new world by looking at our own world in unfamiliar ways.

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.

A formative influence on my undergraduate self was the response of a respected elder statesmen of the Oxford Zoology Department when an American visitor had just publicly disproved his favourite theory. The old man strode to the front of the lecture hall, shook the American warmly by the hand and declared in ringing, emotional tones: "My dear fellow, I wish to thank you. I have been wrong these fifteen years." And we clapped our hands red. Can you imagine a Government Minister being cheered in the House of Commons for a similar admission? "Resign, Resign" is a much more likely response!

I think the world's always a better place if people are filled with understanding.
