Thomas More, Tommaso Campanella, Francis Bacon and Karl Marx all painted pictures of a future in which there is a strong sense of community, in which work is fulfilling and leisure is used wisely and creatively. Even Marx, who is remembered more for his economic and political theories, started out with a vision of everyday life in the communist society, where a person might "hunt in the morning, fish in the afternoon, rear cattle in the evening, criticise after dinner".

If idealism without a dose of reality is simply naive, realism without a dash of imagination is utterly depressing. If this really was the end of history, it would be an awful anticlimax. Look at the way we live now, in the west. We grow up in increasingly fragmented communities, hardly speaking to the people next door, and drive to work in our self-contained cars. We work in standardised offices and stop at the supermarket on our way home to buy production-line food which we eat without relish. There is no great misery, no hunger, and no war. But nor is there great passion or joy. Despite our historically unprecedented wealth, more people than ever before suffer from depression.

The major political parties are reduced to tinkering with the details of our current system. Their only objective seems to be: more of the same, only perhaps a little bit more cheaply. They have no grand vision.

It is this complacency, this lack of idealism, that is in part responsible for the repugnance with which Muslim extremists view western society. When George Bush speaks of exporting democracy to the Middle East, he should realise that liberal democracy on its own is a limp, anaemic idea. If the west is to provide a more inspiring ideal, then it is time we devoted more thought to the questions that Plato, More and Marx placed at the heart their utopias; the question of how to make work more rewarding, leisure more abundant, and communities more friendly.
