Stories turn anonymous strangers into people who matter.

I have two teenage sons, and they're both surviving, thriving, and having a great time, and they're always on social media.

I think if we could turn the dial a bit, and try to take what the philosopher Henry Sidgwick called "the point of view of the universe", and look from above, and realize that we are not special, none of us are, I think it would just cause a transformation.

Individuals differ in how empathic they are. Some people would really flinch if they watched me hitting my hand with a hammer, and other people would just not care.

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.

This enthusiasm [for empathy] may be misplaced. Empathy has some unfortunate features – it is parochial, narrow-minded and innumerate. We’re often at our best when we’re smart enough not to rely on it.

We don't just respond to things as we see them, or feel them, or hear them. Rather, our response is conditioned on our beliefs, about what they really are, what they came from, what they're made of, what their hidden nature is.
