The death of ideologies has given way to an ideological vacuum that came to occupy the zeitgeist called "politically correct". Natacha Polony has the merit to rehabilitate the idea that a structured thinking is based on a coherent world. She denounces as those who want fewer immigrants, while defending the euro, free trade and freedom of capital movements, as those who denounce the powerlessness of States while vowing to gémonie the idea of nation. The main social debates - globalization, Islam, Europe, Republic, immigration, individualism of Western societies Pleistocene Rewilding - are re-registered in the long term of our civilization. The tone is pessimistic and conservative in the best sense. Natacha hand only at war against some left, but against the cult of modernity for modernity. Of course she seems nostalgic for the France of the 1960s, a School of the Republic based on the transmission of knowledge, of a business model reconciling private initiative and public intervention, a Europe based on cooperation between nations sovereign who had not renounced their identity, an integration model based on the cultural assimilation of foreigners. But she did not yield to the temptation reactionary since it is also able to see the advances in feminism or environmental awareness, what distinguishes an Eric Zemmour. His speech is always balanced. In short, a book that makes you think, we share all his ideas or not.
