“It seems to me something like this: every so often, perhaps once in a century, there’s a sort of act of faith. A well of faith fills up, and there’s an enormous heave forward in one country or another; and that’s a forward movement for the whole world – because it’s an act of imagination of what is possible for the whole world. Then the cruelty and the ugliness get too strong and the well runs dry. Then the well slowly fills again. And then there’s another painful lurch forward…because every time, the dream gets stronger. If people can imagine something, there’ll come a time when they’ll achieve it”.
