Good review in Globalethics.org on Prof. Kwame Anthony Appiah's new book entitled "Cosmopolitanism: Ethics in a World of Strangers". Prof. Appiah tries to define some values which should be universal - like obligations to others beyond the family circle, and taking seriously the value of a human life. And goes into distinctions between benign and malign forms of universalism. If the world is a global village, we are going to need discussions like this.
