Certainly our cultural fallback position seems to be that our technologies will get us out of everything they have got us into. That looks like a magical thinking to me, but we don't really have a better idea.

We like to think that the fate of the Earth and the fate of human worlds are the same thing, but we're not as important as that.

We enjoy telling ourselves that we will soon be gods, masters of the planet, manipulating the genes of living creatures and rebuilding the world at a nano-level as we lie back in our hammocks, attended by our robot servants. I don't believe a word of it, and I'm not sure many of us do.

I do think that the legacy of the Norman conquest is still strong in Britain. Our hereditary monarchy, our established church, our ancient county structures, though hollowed out in many ways, are a direct result of what happened in 1066.

What does interest me is how difficult my culture seems to find it to look the dark side of life directly in the eye. It seems to me that if we look back at mediaeval culture, for example, we see a society which faces the reality of death and pain and limitation, because it has to. Our society, which is progressive and technological and seems to have a slightly fanatical utopian edge to it, gets very uncomfortable when anybody highlights the dark side of humanity, or the world we have built, or what we are doing to the rest of life on Earth.

The mountains and moors, the wild uplands, are to be staked out like vampires in the sun, their chests pierced with rows of five-hundred-foot wind turbines and associated access roads, masts, pylons, and wires.
