BHL and Houellebecq deliver through this book (which is easy to read) some of their flaws. Houellebecq reveals a megalomaniac overdue and BHL pretentious dandy in search of "performance". Without confessed is half redressed ... The rest contains many philosophical and literary references that those who have not read Nietzsche, Malraux, Baudelaire and Schopenhauer may not understand. It would be interesting that these two intelligent and educated men take advantage of this exchange to speak a little more about them and their disappointments with journalists to discuss their views on the world, humanity and its evolution. In short, to broaden the debate a bit.
