I guess what I'm trying to say is that whatever weirdness was going to be in there, I felt, had to be earned. And it had to be required by the emotional needs of the book.

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.

I've been reading about and writing about the Civil War period and it is so striking that slavery was never made right - [Abraham] Lincoln was killed, Reconstruction came along, and all of that inequity was frozen in place and carried forward rather smugly. So I think the burden is now upon us white people, to say that this systemic inequality offends us.

Err in the direction of kindness.

Now, we don't really believe these things - intellectually we know better - but we believe them viscerally, and live by them, and they cause us to prioritize our own needs over the needs of others, even though what we really want, in our hearts, is to be less selfish, more aware of what's actually happening in the present moment, more open, and more loving.

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.

The word 'funny' is a bit like the word 'love' - we don't have enough words to describe the many varieties.
