This book has wonderful qualities that I am certain will be picked up by other reviewers. But I would like to add the following. This is the most profound examination of how nationality is enforced on a group of people, with the internal colonization process and the stamping out of idiosyncratic traits. As someone suspicious of government and state control, I was wondering how France did so well in spite of having a big government. This book gave me the answer: it took a long time for the government and the "nation" to penetrate the depth of deep France, "la France profonde". It was not until recently that French was spoken by the majority of the citizens. Schools taught French but it was just like Greek or Latin: people forgot it right after they finished their (short) school life. For a long time France's villages were unreachable.
A great book, a great investigation.
