Any new financial order for the world must tackle the three chief challenges of our age.

Nature is not simply a technical or economical resource, and human beings are not mere numbers. To suggest that one can somehow align all the squabbling institutions of science, environmental management, government and diplomacy in an alliance of convenience to regulate the global climate seems to me optimistic.

Europe and North America, we are told, are less dependent on energy-intensive heavy industry than in the 1960s and 1970s. It seems we squeeze more GDP out of a barrel of oil than in those benighted days.

All UK nuclear power stations should be shut down without delay.

For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.

One of the consequences of the Iranian revolution has been an explosion of history. A country once known only from British consular reports and intrepid travelogues is now awash with historical documents, letters, diaries, grainy video, weblogs and secret police files of questionable authenticity.

In rising financial markets, the world is forever new. The bull or optimist has no eyes for past or present, but only for the future, where streams of revenue play in his imagination.
