"I think we live in a time of catastrophe. I don’t think that’s something specific, necessarily to how we live today. I think we’ve always had catastrophes in history—modern history and ancient human history. I think what’s different this time is how catastrophe is projected. And by that I mean it’s taken the form of spectacle almost. It’s very much image-based. And that’s very much a reflection of technology and the fact that we spend so much time watching television and our screens, whether it’s computer screens or our TV sets at home or movie theaters…The book is also about giving meaning to the improbable and being prepared for the improbable, whether that improbable is a catastrophic thing like the collapse of the World Trade Center, which was a horrific event, or falling in love."
