So there's much more to life than one's intelligence score. To be a decent human being. To have some character.

All of us know high-I.Q. people with whom we don't want to be in the same room.

I teach child development and social policy as an undergraduate course, and I tell my students, "Look, on any of these issues, if you don't want to work on it for thirty years, don't start."

I study children, and they're my subjects in my studies. They're my colleagues, really, all these little kids. And I owe them.

I don't think if you take somebody's temperature a lot that will make them well.

Kids do better, frankly [when the economy is strong]. Jobs make great years for kids.

I guess if you're doing God's work, whatever you do is in His name.
