"I wrote this book at a time when I was worried about the way things were going in this country four years ago. Too many people were afraid of their shadows; there was a threat of book burning. Many of the books were being taken off the shelves at that time. And of course, things have changed a lot in four years. Things are going back in a very healthy direction. But at the time I wanted to do some sort of story where I could comment on what would happen to a country if we let ourselves go too far in this direction, where then all thinking stops, and the dragon swallows his tail, and we sort of vanish into a limbo and we destroy ourselves by this sort of action."
