The crisis that we inherit when we come to power will be the occasion for fundamental change and not the excuse for postponing it

A faith is something you die for; a doctrine is something you kill for; there is all the difference in the world.

It is obvious I shall have to abandon my hopes of getting the Queen's head off the stamps.

I'm interested in language. We used to call it the War Office. Then it became the Ministry of Defence. We used to talk about the hydrogen bomb, now we talk about a deterrent. And the language is very cleverly constructed to give the impression that it's not what it is.

I was radicalised by being a minister. That's when I saw how the system really worked. And that is not a very usual process, but it certainly happened to me: it gave me a lot more experience, it helped me to understand where power really lay, develop strategies for undermining or changing it, and so on. But that isn't the norm. Mr Gladstone moved to the left as he got older, and one or two other people have, but normally you swing the other way.

When somebody comes up with a progressive idea, to begin with, you're mad, bonkers. Then if you go on, you're dangerous. Then there's a pause. Then you can't find anyone who can say they thought of it in the first place. That's how progress is made. This is why I do believe in the vote. In the end, all these people who've been tempted to the right realise the warning lights in their constituency are brighter than the bright lights from No. 10 offering them things.

I've made every mistake - but mistakes are how you learn.
