He is one of the mouthpieces of the French Ruling Elite ; supposedly being a philosopher, he was a member of the "antitotalitarian left" in the 70's, and like his colleagues Finkielkraut and Glucksmann, has moved rightward ever since ; unlike them, he didn't campaign for Sarkozy (but he chronicles in the Right-wing news weekly Le Point)
He is more a essayist than a real philosopher, but his look (esthetically unbuttoned at the top shirt, long flowing hair), easy, "moral" discourse, make him a favorite in the media.
He is extremely ego centric (also from a wealthy family : he lives in hotels so he has a tenuous link to "reality"). He doesn't hesitate to use the system for personal publicity. He is sometimes a bit insightful, very often ridiculous. Un roi sans divertissement est un homme plein de misères
