The Harvard law professor Alan Dershowitz is now arguing for giving proper legal status to torture. "Torture is a matter that has always been unacceptable, beyond discussion. Let's not pretend, those days are passed. We now have ticking-bomb terrorists and it's an empirical fact that every civilised democracy would use torture in those circumstances." Dershowitz doesn't like the "surreptitious hypocrisy" that allows torture but pretends it doesn't. Look, he says, at the case of Khalid Sheikh Mohammed, the Al-Qaeda planner captured in 2003 in Pakistan. American interrogators subjected him to "water-boarding", effectively threatening him with drowning. This wasn't classified as torture because he wasn't hurt, but of course it was.
Dershowitz thinks a legal basis for torture would prevent abuses like the horrors perpetrated in Abu Ghraib prison in Iraq. If, for example, Tony Blair or George Bush had to sign a torture warrant, the whole business would be kept visible and legal. For Gray, torture represents obvious regress. Dershowitz partly agrees but argues that progressives must be ready to do deals. "Terrorism is a major step backwards in civilisation. Hitler was a major step backwards. Sometimes we have to step backwards too to combat such things. But progress happens in other areas. A generation now growing up may have to accept more security measures and less privacy, but in other areas like sexual conduct we are making progress. I don't think overall we are making a step back."
Progress, therefore, is faltering but, on aggregate, it moves in the right direction. Hitler was defeated and judicial torture may, in time, defeat terrorism. We just have to accept that three steps forward also involves two steps back. The point is to keep the faith.
But what if it is just faith? What if the very "fact" of progress is ultimately self-destructive? There are many ways in which this might turn out to be true. First, the human population is continuing to rise exponentially. It is currently approaching 6.5 billion, in 1900 it was 1.65 billion, in 1800 it was around a billion, in 1500 it was 500m. The figures show that economic and technological progress is loading the planet with billions more people. By keeping humans alive longer and by feeding them better, progress is continually pushing population levels. With population comes pollution. The overwhelming scientific consensus is that global warming caused by human activity is happening. According to some estimates, we will pass the point of no return within a decade. Weather systems will change, huge flooding will occur, and human civilisation if not existence will be at risk. This can be avoided if the US and China cut their carbon-dioxide emissions by 50% at once. This won't happen, as they are fighting an economic war with progress as the prize. There are many other progress-created threats. Oil is one diminishing resource, and fresh water is another, even more vital one. Wars are virtually certain to be fought to gain control of these precious liquids.
In addition, antibiotic drugs are currently failing through overuse. No new generation of medicines is likely to be available to replace them in the near future. People may soon be dying again from sore throats and minor cuts. The massive longevity increase in the 20th century may soon begin to reverse itself.
Joel Mokyr's response to all this is that our open-knowledge societies will enable these problems to be solved. John Gray replies: "This is faith, not science." We believe we can fix things, but we can't be sure. And if we can't, then the Earth will fix them herself, flicking the human species into oblivion in the process.
Of course, the end of the world has been promised by Jews, Christians, Muslims and assorted crazies with sandwich boards for as long as there has been a human world to end. But those doomsdays were the product of faith; reason always used to say the world will continue. The point about the new apocalypse is that this situation has reversed. Now faith tells us we will be able to solve our problems; reason says we have no answers now and none are likely in the future. Perhaps we can't cure cancer because the problem is simply beyond our intellects. Perhaps we haven't flown to the stars because our biology and God's physics mean we never can. Perhaps we are close to the limit and the time of plenty is over.
The evidence is mounting that our two sunny centuries of growth and wealth may end in a new Dark Age in which ignorance will replace knowledge, war will replace peace, sickness will replace health and famine will replace obesity. You don't think so? It's always happened in the past. What makes us so different? Nothing, I'm afraid.
WHY I AM SAVING THE WORLD
So, as a new Dark Age approaches, are you just going to carry on living your life as if nothing has changed? John-Paul Flintoff, for one, decided he couldn't bury his head in the sand. He explains how he went on a one-man crusade to show that humanity can adapt and survive
I had just dropped my daughter at the nursery when I began to save the world. I mention this detail because it's important to emphasise that Nancy loves her nursery. If she didn't, I wouldn't drive four miles from home — into London's congestion zone, at a cost of £8 a day. I wouldn't have found myself in Connaught Square that morning, fretting about newspaper stories suggesting the price of petrol was going up. I wouldn't have seen a woman sitting inside a peculiar car parked beside me. Nor would I have noticed, on returning to my VW Golf from the nursery, that the car had moved some yards away and the woman had disappeared.
Intrigued, I wandered over and scribbled in my notebook. When I got home I began to investigate what I had seen. It may seem grandiose to describe my actions that morning, and in the days that followed, as "saving the world". It may be factually incorrect, because I may not have averted global catastrophe after all. You decide — but first get your head round the following, rather terrifying background information. A barrel of oil contains the equivalent of almost 25,000 hours of human labour. A gallon of petrol contains the energy equivalent of 500 hours — enough to propel a three-ton 4x4 along 10 miles; to push it yourself would take nearly three weeks. To support economic growth, the world currently requires more than 30 billion barrels of oil a year. That requirement is constantly increasing, owing to population growth, debt-servicing, and the rapid industrialisation of developing countries such as India and China. But we are about to enter an era in which less oil will be available each year. And many believe that industrial society is doomed. Are we really running out?
