This is, in a sense, a book about the 'what not to do' lessons of the past 10,000 years. It is as much proscriptive as it is prescriptive yet at no point does Wright come across as preachy or imploring (not that both haven't been or won't be necessary). Rather, he makes a thoroughly compelling argument for the "long-term thinking" that is so obviously needed - and soon - if we are to survive as a species and as a planet.
Since finishing the book this morning I have noticed two things: I have begun to think more long-term about the things I do and the choices I make; and I have been making a mental list of the people that I want to read this book. Leaders in business and politics leap to mind, but failing that, I hope that you will. I don't think that you'll regret it.
