He was one of those persons, certainly, but my sister, my grandmother and uncle who raised me, who taught me, by their actions, that it was good to be good, that it was nice to be nice, influenced me more than any other persons have since that time.

So Quigley taught a course called “The History of Civilizations,” and at the end, he said that the great gift of Western civilization to the human race was the idea of progress in a very specific way. He said it was the idea that the future can be better than the present and that every single person, not just the rulers, not just the elected leaders, not just the billionaires, every person has a personal moral obligation to make it so, to keep it going, to make the future better. And it resonated with me. I thought, “That’s the purpose of politics.” It made me really think even more than I had before that I might like a career in public service. It also made me aware of why in the aftermath of something like the 2008 crash you are going to have so much disorientation and anger and frustration because too many people have gotten up every day, and some still do, and looked in the mirror and thought all their tomorrows were going to be like yesterday. It’s the ultimate disempowerment. There’s nothing you can do for yourself, and even worse, for your family. It’s going to be all the same, and Quigley made us understand that our whole culture in Western civilization was designed to counter that, to believe that you personally could make a difference, and I never got over it.

I think I have been mentored by many extraordinary judges in my career, but there’s one in particular that probably changed the course of my life on the court. And that’s Justice John Paul Stevens and the one year we overlapped.

My first, most important mentor was Paulette Bates Alden, who taught at the University of Minnesota when I was a junior and senior there. I took my first fiction writing workshop from her. She was teaching in the MFA program and I was an undergrad student and such an upstart that I asked her to let me in the class. She was generous and great.

In fact, what I usually say to people, “Probably some of the most successful scientists are the ones that know how to deal with failure well.” Because it’s easy to feel good when you succeed. That’s an easy thing. But you’re probably going to fail in science a lot more than you succeed, so you really have to learn how to deal with it and not let it beat you.

A typical day is probably lots of meetings and stuff. But if it’s an idea that we’re developing, what might happen is I might talk to some of the people in the lab, maybe have them come in the office and brainstorm with them, and say, “Well, here’s a problem that we need to solve,” or need to solve better. So just as an example, when I had this idea that we could create better materials, I got about four or five people together with different backgrounds — chemistry, engineering, safety, toxicology — and we started putting chemical structures on the blackboard and say, “Well, this might work,” or “This might not be safe,” and ended up with certain structures that we thought would be good. And then, one of the guys would go out and try to make those structures, and we’d go from there.

I didn’t realize that scientists were like that, and that people were like that. I would have thought — and I like to hope — that I encourage people rather than discourage people. I think you can say no and still say, “Boy, that might be a tough problem, but if you really work at it maybe you’ll solve it,” rather than, “No, it will never happen.”
