I view this book as one that challenge you to expand your horizon of view, in this case about humankind and the set of rules we've been living in our social structures and systems. There are lots of arguments that are contrariety to each other, however it poked our mind to think deeper and broader about the subject.
There are plenty of points made very subjectively according to the writer's conception instead of factual premises. However it's still enjoyable and good especially for those who are relatively new to history and how it affect the current era.
