As the English say, this book contains the "food for thought", ie the incitantes ideas. By necessarily well-argued, but ideas that we can not ignore and which we return, if only to refute them. Compared with other books of Todd, I found it neat months. The introduction, in particular, seems quite messy with the ideas expressed in half. For example, if you can not blaspheme his own religion, while this right is he extends the longstanding atheists? I much liked the suite, which is developing several ideas, which I list here some. First, the French having given more recently to Catholicism have a more unequal anthropological funds outside the Paris basin and the Mediterranean. Leaving religion, they replaced the belief by a strong investment in so-called "left parties", which made the policy of these unequal parties. Furthermore, to define their identity, these new non-believers need a religious frame of reference against which to fight. As Catholicism died, they took Islam (alive) as a reference point. Like the other books of Todd I read, I found the rather verbose presentation (but you have to justify the 18 euros, is not it?).
