Every president, Democratic or Republican, simply works on the supposition that it's better to keep jobs in America than let them go to Mexico.

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. When Obama wanted to bomb Syria, he drew our attention to the victims of chemical warfare. And in both of the Iraq wars, politicians said, "Look at the horrific things that are happening." I'm not a pacifist. I think the suffering of innocent people can be a catalyst for moral action. But empathy puts too much weight on the scale in favor of war. Empathy can really lead to violence.

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.

You might argue on utilitarian grounds that the best way for the world to work is for everybody to take care of themselves first. And people have made that argument. But I just think we would be so much better off if we could care for distant others even a little bit more.

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

I think there's some evidence that we're empathic by nature. There is some evidence from studies of babies and young children that they resonate with the pain of others, and there's some work by Frans de Waal that other primates also resonate with the pain of others.
