I have decided to take whatever my disease can throw at me.

I don't envy or much respect people who are completely politicised.

Bertrand Russell used to employ the method of "evidence against interest"; in other words of deciding that a critique of capital punishment, say, carried more weight if it came from a prison governor. (My friend John O'Sullivan puts it like this: If the pope says he believes in God, he's only doing his job; if he says he doesn't believe in God, he may be on to something.)

Islam makes very large claims for itself. In its art, there is a prejudice against representing the human form at all. The prohibition on picturing the prophet - who was only another male mammal - is apparently absolute. So is the prohibition on pork or alcohol or, in some Muslim societies, music or dancing. Very well then, let a good Muslim abstain rigorously from all these. But if he claims the right to make me abstain as well, he offers the clearest possible warning and proof of an aggressive intent.

Chemotherapy isn't good for you. So when you feel bad, as I am feeling now, you think, 'Well that is a good thing because it's supposed to be poison. If it's making the tumor feel this queasy, then I'm OK with it.'

In one way, traveling has narrowed my mind. What I have discovered is something very ordinary and unexciting, which is that humans are the same everywhere and that the degree of variation between members of our species is very slight. This is of course an encouraging finding; it helps arm you against news programs back home that show seething or abject masses of either fanatical or torpid people. In another way it is a depressing finding; the sorts of things that make people quarrel and make them stupid are the same everywhere.

Evolution is, as well as smarter than we are, infinitely more callous and cruel, and also capricious.
