And the ideologies trailed after these impossible events like condemned prisoners, as ideologies do when they've had their day. Because they have no heart of their own. They're the whores and angels of our striving selves.

I think that most of my books are part of some process of self-education, often about the places I go to. Most of all, they are about the peculiar tension between institutional loyalty and loyalty to oneself; the mystery of patriotism, for a Brit of my age and generation, where it runs, how it should be defined, what it's worth and what a corrupting force it can be when misapplied. All that stuff is just in me and it comes out in the characters. I don't mean to preach, but I know I do, and I'm a very flawed person. It's quite ridiculous.

I don't think that there are very many good writers who don't live without a sense of tension. If they haven't got one immediately available to them, then they usually manage to manufacture it in their private lives.

It's part of a writer's profession, as it's part of a spy's profession, to prey on the community to which he's attached, to take away information - often in secret - and to translate that into intelligence for his masters, whether it's his readership or his spy masters. And I think that both professions are perhaps rather lonely.

I once heard someone say morality was method. Do you hold with that? I suppose you wouldn't. You would say that morality was vested in the aim, I expect. Difficult to know what one's aims are, that's the trouble, specially if you're British.

I think I'm in the same mood as ever, but in some ways more mature. I guess you could say that, at 65, when you've seen the world shape up as I have, there are only two things you can do: laugh or kill yourself.

It's easy to forget what intelligence consists of: luck and speculation. Here and there a windfall, here and there a scoop.
