• 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.
