Notice that all the traditional things philosophers do, looking for validity and soundness, promote civic friendship. That sounds pretty pie in the sky, yes, but I actually believe it.

The thing that I find so bad about anger is the desire for payback. Of course, it is very human to wish for revenge. Your mother has died in the hospital, and the first thought a lot of people have is, I'll sue the doctor. You feel helpless, and you think, I'm less helpless if I'm doing something active that makes someone else pay. And social media make it easy to inflict all kinds of pain on other people. But what good does it do?

I am a very big fan of the nation, actually. In Cicero's time, there was this idea that although we were members of the whole world of human beings, we also needed to connect our imaginations to a smaller unit. The smaller unit was something we knew we could live or die for, as Cicero died for the Roman republic.

As we tell stories about the lives of others, we learn how to imagine what another creature might feel in response to various events. At the same time, we identify with the other creature and learn something about ourselves.

The great philosophers of the past who wrote so beautifully - Rousseau, John Stuart Mill - had to write beautifully because they had to sell their work to journals. They had to sell books to the general public because they could not hold positions in universities. Mill was an atheist, and, therefore, could not hold a position in a university.

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

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.
