I favor a form of cosmopolitanism that takes nations very seriously, particularly because of the role of national law in sustaining or, unfortunately, undermining human rights. Some cosmopolitans take the metaphor of global citizenship - the etymology of the word, after all, just comes from a Greek phrase meaning citizen of the world - to rule out taking national citizenship seriously. I think that's a big mistake. Why can't I be loyal to America and to humanity? After all, I can be loyal to America and to New York city!

But there's a more ordinary sense of resonableness, which involves not just logic but a sensitivity to other peoples real concerns, a desire to understand, even when you don't agree. Many people are reasonable in this way.I'm willing to think that the world will be made better by the conversations of reasonable people, even if there are unreasonable people and people who don't want to converse as well.

I started philosophy looking for answers. But along the way I came to prize exploring the questions. Progress in philosophy consists, I think, in a clearer delineation of the conceptual options, not in reaching determinate conclusions.

Plenty of people within the Moslem world are not engaged in a clash with te West and don't want to do so; and none of the terrorist acts was an attack by the Moslem world on the West. They were attacks by particular groups of Moslems on particular Western individuals or nations. If we allow ourselves to de driven to thinking of every Moslem as an enemy or every Westerner as a friend, for that matter in these circumstances, we'll have no basis for moving forward.

In life, the challenge is not so much to figure out how best to play the game; the challenge is to figure out what game you're playing
