‘Everybody knows what must be done if the world is to continue to be a liveable place, if our homes are not to be invaded by the sea, or by creatures like that spider. Everybody knows … and yet we are powerless, even the most powerful among us. We go about our daily business through habit, as though we were in the grip of forces that have overwhelmed our will; we see shocking and monstrous things happening all around us and we avert our eyes; we surrender ourselves willingly to whatever it is that has us in its power.’
