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.

The irrationality of disgust suggests it is unreliable as a source of moral insight. There may be good arguments against gay marriage, partial-birth abortions and human cloning, but the fact that some people find such acts to be disgusting should carry no weight.

I think Americans are always going to care more about Americans than about Mexicans.

I argue that we should be kind, we should be compassionate, and we should definitely be reasonable and rational, but that empathy leads us astray.

Families survive the terrible twos because toddlers aren't strong enough to kill with their hands and aren't capable of using lethal weapons.

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.

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.
