I’ve been emphasising here the small and the private, because essentially that’s what my work is about. One person writing in a quiet room, trying to connect with another person, reading in another quiet – or maybe not so quiet – room. Stories can entertain, sometimes teach or argue a point. But for me the essential thing is that they communicate feelings. That they appeal to what we share as human beings across our borders and divides. There are large glamorous industries around stories; the book industry, the movie industry, the television industry, the theatre industry. But in the end, stories are about one person saying to another: This is the way it feels to me. Can you understand what I’m saying? Does it also feel this way to you?

Although my years at Irvine were very productive, I missed not doing experiments myself because of the many responsibilities associated with a faculty position: teaching courses, supervising graduate students, meetings, etc. After spending seven years at Irvine as Assistant and then Associate Professor, I decided to move to a non-academic position. I joined the Molecular Physics and Chemistry Section at the Jet Propulsion Laboratory in 1982. I had a smaller group – only a few postdoctoral fellows – but I also had the luxury of conducting experiments with my own hands, which I enjoyed very much.

I looked straight across at the clock and I was disappointed with the time. I should have run under 49 and I didn't. And I knew I had a lot more in me.

What is rewarding about the priesthood is, one, that you have an incredible privilege of being privy to some of the most extraordinary things about people. I mean, as their parish priest, you visit people who are sick, say, on their death bed and they tell you things that they probably have not shared with any other person. You are privileged to bring the Holy Sacrament to people at a time when they are probably at their lowest. But you also have the privilege of meeting up with people at their moment of great joy, when they are getting married, or when they have a child baptized.

But my answer is this: inspiration is not the exclusive privilege of poets or artists generally. There is, has been, and will always be a certain group of people whom inspiration visits. It’s made up of all those who’ve consciously chosen their calling and do their job with love and imagination. It may include doctors, teachers, gardeners – and I could list a hundred more professions. Their work becomes one continuous adventure as long as they manage to keep discovering new challenges in it. Difficulties and setbacks never quell their curiosity. A swarm of new questions emerges from every problem they solve. Whatever inspiration is, it’s born from a continuous “I don’t know.”

All sorts of torturers, dictators, fanatics, and demagogues struggling for power by way of a few loudly shouted slogans also enjoy their jobs, and they too perform their duties with inventive fervor. Well, yes, but they “know.” They know, and whatever they know is enough for them once and for all. They don’t want to find out about anything else, since that might diminish their arguments’ force. And any knowledge that doesn’t lead to new questions quickly dies out: it fails to maintain the temperature required for sustaining life.
