Our emotional life maps our incompleteness: A creature without any needs would never have reasons for fear, or grief, or hope, or anger.

When I came to Harvard, there were no tenured women except one, who was in a chair reserved for a woman. It's still an uphill battle, and I encountered great sexism in parts of my career, but I have to say that things are a lot better than they used to be. There are many women today doing wonderful work all over the academy.

There are no general-interest media that all of us can tap into. I'm not a good person to talk to about social media. I just avoid it. I'm suspicious also of the culture of venting. But the bigger question is, How can we in this media world have a genuine civic conversation? I mean, look at Franklin Roosevelt. He had these radio talks that all Americans listened to, and there was a common civic conversation that came out of it.

We have to change men's expectations, as they grow up, regarding their share of domestic work, of child care, but also of elder care, which is less pleasant and which men don't want to do.

I think the imagination helps us move out of the purely oppositional mentality and see the world in a richer and more variegated way.

The GDP approach doesn't address many aspects of human life: health, education, political liberty, religious liberty, employment opportunities. And these are not all that well correlated with gross domestic product. We also have to think about equality among groups. And freedom of speech and religion. China always ranks near the top of developing countries these days, but there are lots of things we might see as lacking in China.

Disgust relies on moral obtuseness. It is possible to view another human being as a slimy slug or a piece of revolting trash only if one has never made a serious good-faith attempt to see the world through that person’s eyes or to experience that person’s feelings. Disgust imputes to the other a subhuman nature. How, by contrast, do we ever become able to see one another as human? Only through the exercise of imagination.
