The thought that my mother would suddenly be a foreigner would upset me very much.

Experience is the only real teacher and if you keep a diary you get three bites at educating yourself - when it happens, when you write it down, and when you reread it and realise you were wrong. Making mistakes is part of life. The only things I would feel ashamed of would be if I had said things I hadn't believed in order to get on. Some politicians do do that.

I do not share the general view that market forces are the basis for political liberty. Every time I see a homeless person living in a cardboard box in London, I see that person as a victim of market forces. Everytime I see a pensioner who cannot manage, I know that he is a victim of market forces

The nature of the economic system should be a matter for public choice, and free market capitalism should not be accepted without any discussion of the rich variety of alternatives ... Unlike civil laws, economic laws are imposed on people with all the authority of immutable laws of nature. But the economy is created by people, supported by government intervention, regulation, statute and subsidy, and implemented in such a way that it gives substantial wealth and power to a privileged few, while the majority face a life of relentless work, stress and periodic financial insecurity.

I try not to make political arguments personal. It doesn't help and it switches a lot of people off. The real questions: Will we have peace? Will we have justice? Will we have pensions? Will we have free education? Will we have public services? .... those are the sort of things which interest me. I don't think that having a go at individuals really helps get your point across apart from anything else.

If one meets a powerful person - Adolf Hitler, Joe Stalin or Bill Gates - ask them five questions: 'What power have you got? Where did you get it from? In whose interests do you exercise it? To whom are you accountable? And how can we get rid of you?' If you cannot get rid of the people who govern you, you do not live in a democratic system.

There is no connection between imperialism and democracy. I mean when we ran an Empire which we did when I was born, there was no democracy anywhere.
