It's ultimately the purpose of education to cultivate the love of learning for its own sake.

Economics has increasingly become the science of human behavior in general, and it's all the more unlikely to think that it can possibly be value-free - and, in fact, it isn't. Economics rests on un-argued assumptions that need to be examined.

I think part of being a parent, to love one's child, is to accept them as they come - not to see them as instruments of our ambition or as creatures to be molded, as if they were themselves commodities.

Today if you look at most economic textbooks, economics is not defined by subject matter. It's presented as a science of social choice that applies not only to material goods - not only to flat-screen televisions - but to every decision we make, whether it's to get married, or to stay married, whether to have children and how to educate those children, or how to look after our health.

In most of our lives, we are accustomed to aiming at mastery and control and dominion- - over nature, over our lives, over our jobs, over our careers, over the goods that we buy.

In some parts of the world, that sex selection for boys - and it's usually for boys - reflects sex discrimination against girls, and it leads to very large imbalances - in China, in Korea, in India - in the population between boys and girls, a vast disproportion of boys to girls, and it reflects really this discriminatory attitude toward girls.

Most economics that is taught in college and universities today projects itself as a value-neutral science. This claim has always been open to question, but I think it's especially in doubt today.
