The attacks in January 2015 tore a veil. It took as icons of the Left, designers and journalists from Charlie Hebdo, are murdered by young men from immigrant become criminals in the name of exacerbated difference, namely radical Islam for that especially in the Left intellectual and media, we finally understand the importance of identity problems and dangers they convey. What the author, Laurent Bouvet, explains very well in this book published before the attacks is that for years the identity claims rose the Left, true to its tradition of "economy first," downplayed . If economic insecurity had precedence over cultural insecurity in the minds of voters then it is the Left Front that would advance or is the National Front, which has made these identity thematic her business, which collects more and more votes. The paradox is that at the same time, the Left having more or less renounced social transformation (European pressure forced), promoted societal and affirmation of minorities and particular cultural identities other than those of a true composite majority but relatively homogeneous culturally. Now this "central bloc" lived too, in a growing cultural insecurity. And this not only because of the immigrant presence or greater media visibility minority but simply because of the acceleration of technical progress in itself anxiety (Laurent Bouvet does not mention this important factor yet). The author does not merely a now widely shared observation, it offers at least if not solutions guidance and recommendations include emphasize what we have in common rather than our differences. With this in mind you probably do not it will be enough to upgrade secularism and republican pact, but necessary things may appear very abstract. It probably above all learn to love France, its language, its history and even geography (how many kids today are commonly they move to California or Thailand, which is a good thing, but do not know their own country and its riches?). Love your country and its culture is not being nationalistic and Laurent Bouvet reminds us that all borders as limits reassuring and do not imply necessarily fall but often curiosity elsewhere. The Right is currently paralyzed by the National Front and being absorbed by the boa, it is for men to measure their blindness Left and undertake the necessary course correction: give priority to the social on the societal, the living together in the sharing of universal values rather than affirming the particularities somehow reconnect with its foundations. This book is a good contribution to the awareness.
