You'd like this book if you're a nerd. I'm a nerd. I am fascinated by studies that study the mechanisms of studying. Global conceptions of 1st/3rd world, ethnicity, difference, etc. are all mentally constructed, and this book explains the history of certain mental constructions and their implications.
I argue that the war in Iraq is possible because of our mental constructions of the "United States" and "Iraq"- one as a modern, white, developed country- and the other as poorer and back in time. This belief gives the USA the moral authority to invade- because, after all, the knowledge with in the USA is more advanced, and thus has the capability to deal with the primitive barbarity of less developed, third world peoples. This book gives countless insights to that idea.
However, it's technical and advanced- and will take a lot of time if you don't have a strong understanding of global history.
