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.

The cynic about human nature might say that religious morality is an effective way of keeping people in line. The threat of hell, the reward of heaven, but the rules of the holy books are out of date and often barbaric.

Imagine a crime series in which, every week, there is a white suspect and a black suspect. And every week, lo and behold, the black one turns out to have done it. Unpardonable, of course. And my point is that you could not defend it by saying: "But it's only fiction, only entertainment."

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.
