This is a very readable and enjoyable introduction to French "culture." More specifically, the authors want to explain various features of France to North Americans. They are certainly qualified to do this, being fully bilingual journalists; he is Quebecois, she is Ontarian. Though they are Canadian, they are writing for a US audience as much as for a Canadian one, and they regularly compare all three countries.
The book consists of three parts: "Spirit," "Structure," and "Change." The part on Spirit is by far the best. It provides a good entry to diverse aspects of the French mindset, sometimes using the device of "studying the aborigines" in France. These include, for example, the French attitude toward land, their fondness for grandeur, and their notions of private and public space. The section is full of anecdotes and discussions with French people, and these voices come through very well.
The section on "Structure" is much less successful. Perhaps, as a political scientist, I am inclined to be overly critical of those who discuss politics without the analytical apparatus that the discipline uses. Still, I see that other reviewers were also disappointed in this section. I think the problem is that the authors rely too much on "regular people" as sources. This strategy works really well when people are talking about their own views of things, as in the "Spirit" section. It doesn't work so well when people are talking about things outside themselves, especially if those things may require some expertise to understand, such as the economy.
When Nadeau and Barlow make generalizations about France, the US, or Canada, it's important to realize that all three of these are diverse countries. The authors have limited experience in each - - they don't have the same depth of knowledge about (say) Texas, British Columbia, or Marseilles and they do Paris, New York, or Quebec. As a result, the book jacket and other publicity material very much overstates its case. The jacket claims that there are a lot of answers in this book - - read it and you will understand France. Of course, it doesn't work that way. Still, if you read the book you will understand France better than you did before you read the book. You'll also enjoy the journey.
