I've seen [Lalla Ward] episodes of "Doctor Who." They're good, at least partly because the scripts were written by Douglas Adams.

In true natural selection, if a body has what it takes to survive, its genes automatically survive because they are inside it. So the genes that survive tend to be, automatically, those genes that confer on bodies the qualities that assist them to survive.

The fear of Hell is a very powerful motivation.

I'm easily persuaded that a really good novelist who gets inside somebody else's head could be serving a valuable purpose. I enjoy satirical novels that take a wry, humorous, ironic look at modern life.

It is a simple logic truth that, short of mass emigration into space, with rockets taking off at the rate of several million per second, uncontrolled birth-rates are bound to lead to horribly increased death –rates. It is hard to believe that this simple truth is not understood by those leaders who forbid their followers to use effective contraceptive methods. They express a preference for ‘natural’ methods of population limitation, and a natural method is exactly what they are going to get. It is called starvation.

It is immoral to brand children with religion. 'This is a Catholic child.' 'That is a Muslim child.' I want everyone to flinch when they hear such a phrase, just as they would if they heard, 'That is a Marxist child.'

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!
