I am 60, and I am as much an internationalist as when I was younger, when I was a Marxist-Leninist. Internationalism is one of the rare pieces of that heritage to which I remain loyal. That is Barack Obama's strength. A politician has finally understood that politics is not only about the closing of a mine in Ohio-it is also about the will to reach out, to embrace the world of today's young Americans. That way, young Americans may eventually reconcile with politics.

I work even when I am on vacation. You know that line by Stéphane Mallarmé, "All earthly existence must ultimately be contained in a book"? I am the kind of person who finds life interesting only if it is translated into writing, if it is parsed into words.

It's true that in France there is always this ridiculous complex about money. Money is cursed, shameful, money disqualifies you . . . In America, even though it is a Protestant country, it's the opposite.

You can be horrified by the state of the prisons, the misery in certain neighborhoods of its cities, or their level of poverty. Anti-Americanism, by which I mean a hatred for America as such-its transformation into a metaphysical category, which incarnates all the evil in the world-is one of fascism's favorite themes. Look at writer and political theorist Charles Maurras in France. The philosopher Martin Heidegger in Germany. The radical Islamists of today!

The terrorists exist, and I think we must speak to them, not to establish a dialogue-since for serious terrorists that is unfortunately out of the question - but to learn how their brains work, to be better able to fight them.

The European Union should not be prescribing an identity. We know what that's like, when a government tells its people how it should look; what it should be doing. That's the first step towards totalitarianism.

France is a country where thinking is supposed to be furtive, invisible, almost clandestine. France is a country of cliques and sects.
