I kind of like social media, and I like hearing from people. I don't like the ugly stuff, but there are some people - smart people - who have a very different perspective, and I'll get a backlash from them. And this isn't necessarily a bad thing.

When people want to inspire you to turn against some group of people, they'll often use empathy.

I think we're going to care more about Americans than Africans. I don't think that's ever going to go away, and I don't think it's ever going to go away that people care more about their families than strangers, and their communities over other communities. But I think it would transform the world in such a good way if we could just acknowledge, at least intellectually, that an African life and an American life are the same.

My book is going to be called Against Empathy, which may give you a feeling for where my argument is going to go. Whenever I talk about this, I have to begin in the most boring of all possible ways: by defining my terms. By "empathy," some people mean everything that is good - compassion, kindness, warmth, love, being a mensch, changing the world - and I'm for all of those things. I'm not a monster.

I'm very interested in why we do good things, or bad things, and where moral judgments come from.

I draw a lot from Buddhism, which focuses on compassion and kindness, loving kindness, as they call it, but rejects empathy because it's a poor moral guide. And I think there's a lot of evidence suggesting that they're right.

It's hard to pull apart empathy from compassion. What is really clear is that we innately care for other people at least to some extent.
