The understanding that women are not inferior across the world, it's something that you can get from school, not only from the book but also from chatting with other kids. It's a big impact. One of the curious things is that even when - and this we found from studies - the schools are doing pretty badly in terms of their education, about mathematics and literature and language, going to school transformed people because I think the action of schooling, the activity, is very important.

An Arab activist can take pride in the Arab heritage of mathematics and science or he can take pride in his religion, and there's pride to be taken in both. But one of them could be exploited much more easily and has been in the context of world conflict. And the other is very difficult to do on the grounds that science and literature and mathematics have been among the uniting factors in the history of the world.

While I am interested both in economics and in philosophy, the union of my interests in the two fields far exceeds their intersection.

There may be countries [where] there's no gender inequality in schooling, even in higher education, but [where there is] gender inequality in high business. Japan is a very good example of that. You might find cases in the United States where at one level women's equality has progressed tremendously. You don't have the kind of problem of higher women's mortality as you see in South Asia, North Africa, and East Asia, China, too, and yet for American women there are some fields in which equality hasn't yet come.

Your voice is much more articulate and people listen to you if you've been to school. In family decisions, not surprisingly, the biggest impact in reducing fertility is girls' education.

The increasing tendency towards seeing people in terms of one dominant ‘identity’ (‘this is your duty as an American’, ‘you must commit these acts as a Muslim’, or ‘as a Chinese you should give priority to this national engagement’) is not only an imposition of an external and arbitrary priority, but also the denial of an important liberty of a person who can decide on their respective loyalties to different groups (to all of which he or she belongs).

We need to ask the moral questions: Do I have a right to be rich? And do I have a right to be content living in a world with so much poverty and inequality? These questions motivate us to view the issue of inequality as central to human living.
