Steven Pinker

Other people know that you know.

You know that other people know, et cetera.

Blushing, you feel the heat of the blood, the inside in your cheeks, knowing that other people can see the change in color from the outside, and they know that you know that you're feeling it, all the more so when they say, you're blushing.

Mm-hmm, yeah.

I've never had that problem.

That's not a black people.

That's why Stephen pointed at me.

Okay, so maybe you can, for instance, so Darwin worried about this because Darwin was a big proponent of universal emotions.

In fact, for him- He had a whole book on it.

The whole book on the expression of the emotions in animals and men.

Yes, yes.

And he used it, in fact, as an argument against the scientific racism of his day, which said the different races were independently... Evolved.

Evolved or created, one or the other.

Either one.

And he said that the similarity in facial expressions, in many other aspects of emotion, showed that we all descended pretty recently from a common ancestor.

Wow.

And his data, I mean, he was kind of an invalid, but he corresponded with...

colonial officers and missionaries and traders all over the world.

And he had them, gave them questionnaires to ask of their interactions with local people, which they then mailed back to him.

In fact, his, well, his book, this book that we're talking about was the first use of scientific photography, although not for cross-cultural studies because the missionaries didn't have cameras out there in the field.
