If a theory of justice is to guide reasoned choice of policies, strategies or institutions, then the identification of fully just social arrangements is neither necessary nor sufficient.

Women's education has a much greater impact [on], for example, fertility. Men's education, if our studies are correct, ha[s] almost no impact on fertility. Women's do. So, by the way, as a man, it's not to the glory of men specifically that it's women's education that reduces child mortality.

It’s scandalous when one thinks about the people who live in a world in which they need not be hungry, in which they need not die without medical care, in which they need not be illiterate, they need not feel hopeless and miserable so much of the time, and yet they are.

South Korea at the end of the Second World War had a very low level of literacy. But suddenly, like in Japan, they determined they were going in that direction. In 20 years' time, they had transformed themselves. So when people go on saying that it's all because of perennial culture, which you cannot change, that's not the way the South Korean economy was viewed before the war ended. But again within 30 years, people went on saying there's an ancient culture in Korea that has been pro-education, which is true.

Each human being is a citizen of the world. We have many identities, of which one of the identities is our human identity. And that's something that the schools can provide, but that requires again a vision rather than being centers of hatred. It could be an enormous opportunity to give that mission.

I don't think poverty provides that much of an obstacle to education as one thinks. I think the bigger obstacle to education is the fact that it's a very hard thing to do for a first-generation schoolgoer. Because not to have parents at home who can help you, motivate you, is a problem even when the parents are in the abstract very keen on children being educated.

I think education has a bigger impact on the lives of people than absolutely anything else.
