Parenthood is a school for humility. We can't choose the precise traits of our children, and that is morally important. It teaches us what William May, a theologian whom I greatly admire, calls "an openness to the unbidden."

It's true that to speak of an ethic of giftedness, which is very much the ethic that I deploy in raising questions about designer children and genetic engineering - an appreciation of the giftedness of the child or the giftedness of life does have religious resonance, because a great many religious traditions emphasize the sense in which the good things in life are not all our own doing; they are gifts from God.

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

The way things are does not determine the way they ought to be

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.

I think too often in our society parents, who may have good impulses, overreach and try to mold and shape and direct their child.

What intrigued me most was not the technology as such but the questions about the human goods, the fundamental human values and virtues that are raised by debates over biotechnology.
