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

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.

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 do not argue that nature is sacrosanct in the sense that we must never tamper with nature. That would disempower, really, all of medicine. That would mean that we can't combat dread diseases - malaria, polio, all of which are given by nature, if one thinks about it.

One of the ways in which parenting is a learning experience and an opportunity for moral growth is that we learn as parents that we don't choose the kind of child that we have.

What I really want for my children is that they be loved and that they be happy and that they lead a good life.

I'm a supporter of embryonic stem cell research. I do think there are very important moral and also religious questions at stake in the debate over embryonic stem cell research.
