We really have to think about aging because women are living longer than men. More of the people who need care are women. A lot of them are living alone, with no one to care for them, or they're shunted into institutions. I would like to see a sensible aging policy more like what the Nordic countries have. They're cutting back those programs, but there you can still have in-home nursing care. You don't have to rely on your children. I personally don't want to be a burden on my daughter.

There's a gap in perceptions between women and men. Women feel much freer than they did, but still, when alcohol is involved, especially, there's a lot of sexual assault, and a lot of confusion about that. So, we need to focus a lot more on what consent is and on the importance of affirmative consent.

People don't just want to feel satisfied. They actually want to act.

The humanities teach us the value, even for business, of criticism and dissent. When there's a culture of going along to get along, where whistleblowers are discouraged, bad things happen and businesses implode.

The great tragedy in the new feminist theory in America is the loss of a sense of public commitment.... Hungry women are not fed by this, battered women are not sheltered by it, raped women do not find justice in it, gays and lesbians do not achieve legal protections through it.

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.

Economists get impatient with philosophy. They are often trained as skilled mathematicians. They don't like going back to ordinary language and first principles.
