It's a time when a lot of principle virtues are being tested. Do we still believe in the truth? Do we still believe in empathy? Do we still believe the protection of the weakest among us? These are yes or no questions, but the means of communication is all tied up with those virtues and you can't abandon those virtues as you pursue them.

I had to go in and do the work of toning [invented "historical" bits] down in order to make them fit [in Lincoln in the Bardo]. It's like if you're an actor and you're always overacting, well, you're a bad actor. But if you're an actor who subdues yourself to the extent that's necessary, then you're really acting.

It really strikes me how much of your energy in America, especially if you're from a working back-ground, is spent just keeping your head above water. It really saps your grace and your strength.

So many people mentioned this at these rallies. You go to these things and it's kind of like an oldies concert. I mean, it's not hostile.

What I regret most in my life are failures of kindness. Those moments when another human being was there, in front of me, suffering, and I responded . . . sensibly. Reservedly. Mildly.

Nothing will turn you into a Civil War buff like five years of reading. Some of the letters that people wrote from that time are so deep and so beautifully articulate. And you realize, especially with the stuff that's going on now in America, that it's always been chaos - people were disagreeing at least as much as they are now and 20,000 people would die in a day. It's the scale that's amazing, and also the proximity to our own time.

"Kindness" can mean a lot of different things. In this case, I felt I had to present his [Donald Trump's] supporters in as fair a light as possible - many of them hadn't been interviewed before and that entailed some interviewer-courtesy in the editing and so on.
