Doubt, it seems to me, is the central condition of a human being in the twentieth century.

We live in an age where the rate of change has been colossal. Colossal. Almost every week there's some transformation of some kind, whether technological or political or scientific, whatever. And I think it's bewildering to human beings to live in a time when they can't take anything as fixed - when everything is shifting and changing all the time.

Unfortunately, the problem of the free speech argument is that you have to defend people you can't stand.

The response of anybody interested in liberty is that we all have a say and the ability to have an argument is exactly what liberty is, even though it may never be resolved. In any authoritarian society the possessor of power dictates, and if you try and step outside he will come after you.

A little bit of one story joins onto an idea from another, and hey presto, . . . not old tales but new ones. Nothing comes from nothing.

You've got a generation of young men - almost all are young men - in situations of great economic hardship, where they don't really have work. The chances of them making a decent life for themselves, of making a family, living in a kind of decent, happy way, are very, very remote. It's very hard for them to ever even have that as a dream, so when people are that deprived of the ordinary hope of human beings, it creates anger. And that anger can be channeled by unscrupulous persons, whether secular or religious leaders, and there's been a lot of that.

Children like being a little scared, but they don't want to be disturbed.
